Types, uses, and acceptance methods of woodworking materials:
Material types and uses:
Large core board (blockboard): thickness 18mm, thickness 15mm, do a variety of shapes, doors, door covers and so on. Most frequently used. 15mm is used on the door of the cabinet (a layer of 15mm plus two panels of 6mm = 2cm).
9 PCT board: thickness 9mm (generally less than 9mm), do door trim, cabinet back.
Panel: thickness 3mm. Used for veneer. There are many kinds, such as: black walnut, cherry wood and so on.
Australian pine board: The thickness of 3mm is affixed to the base board and the white paint lacquer is directly put on it.
Ou Song board: Thickness 18mm, do the grass-roots use (door cover, wardrobe, etc.), there are also people directly on the brush varnish.
Gypsum board: thickness: 9mm ceiling, and a variety of latex paint styling walls.
Cement pressure plate: thickness 9mm, used for stand-up tube.
Wooden keel: Specifications: 3*4 Most common. Do ceilings, wall shapes.
Light steel keel: According to the use of a variety of specifications, 38 main bones, 50 bones. Ceiling, covered pipe.
Wood lines: According to the use of a variety of specifications. General door line specifications: 1cm*5.5cm
White latex: The panel is attached to the base plate and glued.
Metal dressings: straight nails, nails, round nails, nails, nails, self-tapping and so on.
Basically eliminated materials: plywood, wood keel, all-purpose adhesive.
Acceptance notice:
Daixin brand, manufacturers. Thickness, etc. (Do not use thick plates for cabinet doors).
The thickness of the nine PCT board. Some PCT boards are as thin as 5mm.
Every time the material comes in, it must be inspected. There are many workers. The first time they pull the material is good, the second time they secretly pull some material and use it. You don't know.
Recommended Business:
New homes, home depots and other building materials supermarkets, Lianyi, jade and other wholesalers.
Ceiling construction methods, classification, comparison:
Wooden keel ceiling: keel brush fireproof coating twice, keel open, fixed with nails, each joint is fixed with two nails, made of 300 * 300 or 400 * 400 frame, install the top, (forbidden to use Rows of nails, nails fixed frame), adjust the height, low, straight, gypsum board after acceptance, use self-tapping fixed, self-tapping density: 20cm, the edge part should be dense.
Combination of wood keel and light keel: This practice is not recommended, and I personally feel that it is not as strong as a complete wood keel or a fully light keel. It is troublesome to adjust the straightness during construction.
Full use of light keel: Expansion screws, dowels, etc. are used to make the mounting stronger. Light keel has the characteristics of fire prevention, non-deformation, and firmness, and is widely used by most decoration companies. Whether it is a large area ceiling or a partial ceiling can use this method of construction.
Ceiling Precautions: The keel on the top surface and the wall surface should be fixed with wooden wedges and nails or fixed with expansion bolts. It is forbidden to use the nail (it is easy to fall down. When the gypsum board is installed, the joint between the gypsum board joint and the keel frame is staggered. The fixed gypsum board: It is fixed by self-tapping, but it does not agree with the use of shot nails (more or less nail holes are not easy. Brush anti-rust paint).
Classification of toilets and kitchen gussets and precautions:
Ordinary aluminum buckle plate: Metal texture, superior grade, yellowing resistance, fire resistance and so on.
Integrated ceiling: All electrical appliances and buckle board are in the same plane, neat and beautiful. Yuba can be installed separately.
Plastic gussets: Affordable, colorful, can pack Yang angle and launch riser. However, poor fire resistance.
Matters needing attention: The construction process is: Strike the line on the wall, install the edge strips, install the suspenders, keel holes on the top surface, and install the buckles. Pay special attention to the installation of the top boom, it is best to use expansion bolts, more secure. Before the construction, determine what electrical appliances are on the ceiling? It is best to take the exhaust pipe of the hood, water heater, and exhaust fan to the construction site and pre-install it on the gusset plate. Before installation, check the gussets for flatness (looking at the light), color difference, thickness, etc. After installation, check the buckling plate and check the gap between the ribs and the wall. Large fixtures cannot be placed directly on the gussets, and they should be fixed with a suspender. The edge strips are best secured with nails and are stronger than glue.
Door and window cover construction methods and other types of work with:
Construction method:
First check the width of the door hole to ensure that 800 doors can be installed (the bathroom is generally 700), measure the width of the door cover, blanking, nail base slats, blockboard door frame made of fixed on the base slats, find Vertical, horizontal, nailed nine PCT board (to do cut), plywood, install door line.
The original door frame is not dismantled, nails are bolted directly to the left and right of the original door frame, and panels and lines are installed. It is common in old houses with doors and frames. This method is relatively old and does not guarantee that the door is mounted on one side of the bedroom, but it is located in the middle of the door pocket. Most of the workers are now re-doing the door.
In some Guangxi carpenters, instead of using slats as base layers, they drilled holes directly into the walls, nailed wooden wedges, and the wooden wedges climbed above the wall, and then cut the wooden wedges directly to find vertical and horizontal levels. This method is quick to construct, saves material but does not have solid slats. Cooperation with other types of work:
Cooperation with the Mason: After the grass-roots layer is made, before the panels or lines are attached, the floor tiles will be put on the floor, and after the floor tiles are pasted, the panels and lines will be affixed. Advantages: Because there is a gap between the floor tile and the door cover, it is more ugly. If the final panel, line, can cover the gap, more beautiful.
With the painter's cooperation: after the door base is done well, some walls are not vertical and the door sleeve is not in a plane. After installing the door line, there is a gap between the wall and the door line, which is more ugly. Blocking is also easy to crack. The correct construction method is as follows: After the installation of the base layer of the door cover is completed, make a supplement to the non-vertical wall surface to ensure that the wall surface and the door cover are in the same plane.
The production methods of interior doors are classified and compared:
Empty core door:
1. Two layers of blockboard opening strips are used to make the frame, and the two sides are re-adhesive or Australian pine.
Features: poor sound insulation, uneven surface, light weight.
2. The single-layer large core board is opened and made into a frame, and the two sides are affixed with nine PCT boards and plywood, and the lines are closed.
The single-layer large core board opens up the three points of work, and the two sides are covered with five PCT boards and wooden lines.
Features: Sound insulation is better, the surface is more flat, not easily deformed.
Solid core door:
Two large core plates are pressed directly together (open expansion joints), plywood.
The sound insulation is the best and the weight is heavier. It is best to use three hinges and double groove.
Semi-finished door:
The standard size door (not painted), after buying back, do the door cover according to the size of the door, install the hardware, and then do the paint on the door.
Custom-made door. The construction party will make the door cover directly, after the door cover is done well, the size will be directly customized on the market.
Features: Fast construction, more shape and beautiful appearance. Small deformation.
Completely finished door:
For example, the bamboo doors of the stars, the paint doors of Panpan, the just-wood doors of Maxim, the solid wood doors of Huahe, and the paint-free doors.
Features: Rich shapes, good paint (production in dust-free workshops, no impurities), but the disadvantage is: there are gaps in all interfaces.
Shoe cabinet, entrance construction:
Shoe cabinet: Pay attention to the height of the owner, the size of the shoes, and determine the width of the shoe. Inside the partition can be made oblique (can put down big shoes). The interior of the shoe cupboard is more ash, and the inward slanted baffle, pay attention to leave a gap in it (gray can fall to the bottom). Some workers like to put wallpapers in the cupboards, but the wallpaper in the shoe cupboards (easy to dirty) is best. It is best to paint or plastic film. I personally lazy, do not like to open the shoes every day to open shoes, like to make an open space under the shoe, go home directly to the shoes off, rather than open the door.
Entrance: Many entrances and shoe cabinets are a unified body, which is the first form of home. The quality of the project is particularly important. The same can not be arrogant. In the construction should pay attention to the following points: Active and fixed comparison: If it is a small shoe, it can be made to be movable, in the future to home-like furniture, can be removed, more convenient. There is also a fixed type, in the wood when it is necessary to fix the shoe cabinet on the wall, in order to ensure that the gap between the shape and the wall and to ensure the top shape of the bearing. Function design of shoe cabinets and entrances: It is convenient to change shoes, have a drawer (put a key, and other small things), have an umbrella position, preferably have a mirror (you can look in the mirror when you go out), you can also set a Hooks hanging clothes, the elderly at home, but also set up a pier, do the shoes on the pier will be more convenient.
Construction methods and precautions for wardrobes and bookcases:
Wardrobe: The internal structure of the wardrobe is worthy of careful scrutiny. According to your own living habits, you can identify the various storage areas. The basic areas are: tops, coats, trousers, shoes, quilts, ties, shirts, and underwear. Do you need a drawer? Do you consider concealing the safe? Cabinets with doors, the construction of the door should be: a large core strip, two layers of pressure in the panel. The wrong construction is to paint the entire board directly or stick a panel (easy to deform). Buy Finished Sliding Door Cabinets: Pay attention to the space left for the slide rails, and the sides of the slides need to be painted. In addition, after ensuring the slide rail is installed, the drawer in the wardrobe can be pulled out freely (the drawer is slightly higher, and the lower rail of the sliding door should not be blocked). According to the size of the room, the size of the design cabinet, do not let the space is significantly suppressed. Sometimes, it is not necessary for the cabinet to be topped. It can be sealed with a plasterboard and used as a latex paint.
Bookcase: Above the bookcase, there should be enough space to put some small books and large books (some newspapers and magazines are relatively large). According to their own habits, determine whether the keyboard of the computer is on the desktop or the keyboard drawer? There are many electrical appliances near the study, it is best to install a socket, and then separate a row of plug. There should be a hole on the table, computer monitor line, keyboard line, speaker line, desk lamp line to go to the following.
Interior treatment of wardrobes, bookcases, shoe cabinets, etc.:
PVC film Zhengzhou decoration company commonly used method. Most of the colors are white, with good decorative; with a seal, the harmful gases in the large core board isolated; with a rational, you can use rags casually wipe.
wallpaper:
The basic cost is the lowest, the color is more, and the texture is soft. Disadvantages: Not scrubbing.
Painting Some workers have trouble figuring out that it is difficult to see if the cabinet is not painted or painted directly with some varnish. The best way is to put a varnish on the panel, which is beautiful and easy to handle. Of course, the cost will increase a lot. Or brush paint, do not paste the panel.
The interior of the shoe cupboard: the best paint, the shoes are dirty, the interior of the cabinet is also easy to be soiled, easy to understand after painting. Can also be attached to the PVC film, but also to scrub. Can't use wallpaper, it won't be clean after being dirty.
TV wall construction notes:
TV background wall: There are many methods for the production of TV background wall, plasterboard modeling, wooden paint modeling, glass, stone modeling, and wallpapering methods. It should be considered when making: the location of the wall-mounted TV (pre-embedded or solid ground) and sufficient sockets (suggestion: buried a thicker PVC pipe, all the wires can pass through the pipe to the TV below The cabinets are (DVD line, closed line, VGA line, etc.) Considering the position of the sofa, the position of the sofa is determined, the position of the television is determined, and the shape of the molding wall is determined by the size of the television. Part of the ceiling echoes, there are usually lights on the ceiling, so we must consider the shape of the wall and the lighting echo.When the woodworking TV wall, watching the air-conditioning outlet, do not put the air-conditioning socket to seal up, and to seal the socket also moved When modeling the wall surface, the thickness of the floor tiles and the height of the baseboard should be taken into consideration to coordinate each model. If there is no baseboard for the design, the panel and gypsum board should be installed after the construction of the floor tiles.
Other Modeling Walls: Bedside background wall: Pay attention to the return light lamp After installing the lamp, you cannot see the lamp in bed. Corridor side view wall: The styling should not affect the construction of the side door cover.
Partition construction and precautions:
Partition construction should consider whether there is sound insulation design. Partition wall with soundproof design: First light keel frame, up and down left and right roots (fixed with wooden wedges and nails), the main keel fixed to the world keel fixed using dowels, solid cross between the keels, clamping, through the owner or After inspection and acceptance by Party A, the gypsum board shall be sealed, and after the single-sided sealing is completed, the net keel frame shall be filled with sound insulation materials, and after acceptance, the gypsum board on the other side shall be sealed.
Some ground can not nail, how to fix the partition? The ground or floor heating and water pipelines that have been warmed to ground cannot be identified. The ground can not be used to punch the wooden wedge. How to ensure the firmness of the partition? The keel along the ground can be temporarily fixed with gypsum powder. After installation, the two sides of the keel should be affixed with tiles or wood floors, which can secure the partition card.
The partition can also be used: wood keel, gypsum board fixed. Some bricks are directly built and then plastered.
Precautions: Before installing the plasterboard, make sure that all circuits are properly installed. The gypsum board should be fixed with self-tapping, the density is not lower than 20cm, and the density at the edge is 15-17cm. Gypsum board joints should be left at 3mm gaps to prevent cracking. Gypsum board joints should be fixed to the keel, with transverse seams, and the keel frame should be transversely braced.
About the installation of gypsum board in ceilings and partitions:
Work before sealing gypsum board: after the concealment works before installation. Confirm that the circuit is completed and confirm that the frame is firm. Check the frame's elevation, size, and shape.
Combination with keel: Gypsum board joints should be staggered with the wooden keel frame joints. The joints should be on the keel frame and should not be temporarily connected with wooden keels. A 3cm gap should be left at the joints for crack prevention.
Use self-tapping: Self-tapping should be used. It is forbidden to use a large number of shot screws (small and dense nails, and it is not easy to do rust-proof treatment). The density of self-tapping (national standard): Peripheral density: 150-170mm, central 200mm. Self-tapping should be screwed into the gypsum board and lowered with the plasterboard surface.
Paint treatment: All self-tapping screws should be painted with anti-rust paint. After Party A's supervision and acceptance, it shall scrape the putty. All joints were filled with plaster and bandages were applied to prevent cracking.
The construction method of bag riser is classified and compared:
Brickwork: Constructed by a mason, before the tiling, built with red bricks and wrapped up the risers. Features are: sound insulation, strong, strong, not easy to deformation, not easy to fry after the completion of the magnetic sheet. Disadvantages: Relatively thick, taking up space.
Wooden keel plus cement pressure plate: The most previous construction method, the construction is the simplest and easy. Disadvantages: Wooden keel is easy to absorb water, mold, and cause deformation in the wet environment of the bathroom, so that the magnetic pieces can break. Remedy: After installation, waterproof the root of the riser before attaching the magnetic sheet to prevent ground water from flowing into the riser and immersing it into the wooden keel.
Lightweight keel plus cement pressure plate: Informal method: Use only three light keel and two cement pressure plates. The light keel does not form a frame, but plays a connecting role. This is not strong enough. But the provincial workers save material. Formal method: Use lightweight keel to make the frame. After inspection and acceptance by Party A, seal the cement pressure plate, hang the wire mesh, and finally mount the magnetic piece.
Features: not easily deformed, nowadays the company most commonly used technology.
Plastic buckle plate, plastic aluminum plate production: These two methods are suitable for home renovation finished, but also want to put up the riser. Because it doesn't need a magnetic patch, it's very convenient. Plastic gussets: wooden keel plus Yangjiao line, the buckle plate directly from the bottom up into the installation. Disadvantages: not beautiful. Aluminium plastic board: wood keel nailed nine PCT board, and then use adhesive to glue the aluminum plastic board, there are many colors, close to the magnetic film effect. Disadvantages: The angle of the aluminum-plastic panel is easily cracked, and a thicker plate should be used.
When the carpenter works with the wall in a plane, joint processing:
When the woodworker meets the wall and is in the same plane, if they are directly connected together, it takes a long time. Because they are different materials, there will certainly be cracks between them. How can this kind of crack be avoided? The correct construction method: In the meeting place, with a layering, pressing to the crevice, can solve this problem effectively. For example: When the side of the wardrobe is on the same plane as the wall, use a wooden wire to press it up, or use a gypsum board to press it up to make a latex paint, so that no cracks will occur.
Frequently seen places are shown below:
Entrance and wall in a plane closet and wall in a plane modeling wall and the original wall surface in a plane Note: When designing, try not to put different materials on the same plane, if you must be in the same plane, you should Design a batten and ensure the integrity of the batten, so that the batten is integrated into this element.
Carpentry hardware installation notes:
handle:
The two handles are at the same height, the same distance from the cabinet door.
The handle of the wardrobe is adjusted according to the height of the owner.
The handle of the cupboard is centered or installed under the door according to the lifestyle.
According to the styling, to buy the appropriate handle (embedded or convex?) The drawer inside the wardrobe is generally embedded.
lock:
Before the lock is installed, a key should be kept to prevent the worker from losing the key.
After the lock is installed, check: Is it firm? Is it damaged? Did you break the paint? Is it easy to close? Repeat the lock several times and close it several times to see if there are other problems.
Door hinge:
The solid core door is heavy and it is best to install three hinges.
The mounting hinges should be grooved on both sides of the door and door sleeve. Trough neatly.
The screws on the hinge should be original and should be full.
There should be no traces of paint on the hinges.
Cabinet door hinge:
It should be clean and tidy, no paint stains.
Hinge screws are full.
Check whether the height of the door is consistent with the up and down?
After the door is closed, it should be tight.
Slides:
Drawers should be easy to pull out and advance. If you feel heavy, there is a willingness that the workers are not installed.
Take the drawer down to see if the screw is full or not?
