In the decoration, you may encounter many kinds of plates, and there are so many kinds on the market. Most of them are used in outdoor and indoor decoration, and these materials are mainly divided into five types. Construction of wall decoration board and its material requirements: Dragon aggregate is generally dried with red pine, the moisture content is not more than 12%, and the material shall not have defects such as decay, joint scar, crackle, distortion and so on, and shall be treated with anticorrosion in advance. In creating a beautiful environment plays a very important role in a household products, according to its different functions, the decorative board will be divided into many categories specifically divided into which categories?Construction technology of decorative board wallAnd what is the process? In order to help you further understand the types of decorative boards andConstruction technology of decorative board wallNow let me reveal the answers for you one by one.
Construction technology of decorative board wall
1. Material requirements:
1.1 the tree species, specifications and material grades of wood shall meet the requirements of the design drawings and the "Code for Construction and acceptance of Wood structure Engineering".
1.2 Dragon aggregate is generally dried with Korean pine, the moisture content is not more than 12%, and the material shall not have defects such as decay, joint scar, crackle, distortion and so on, and shall be treated with anticorrosion in advance.
1. 3 15mm thick Blockboard is selected as lining board.
1.4 the panel is made of bamboo silk sound absorbing board.
1.5 excipients: adhesives, preservatives, latex, sodium fluoride (purity should be more than 75%, free hydrogen fluoride, its viscosity should pass 12 kilogram sieve); nails: the length specification should be 2-2.5 times the thickness of the panel.
2. main machines and tools
Small electric table saw, small electric table planer, electric drill, wood plane, large and medium-sized groove planer, wood saw, fine tooth knife saw, axe, hammer, flat shovel, punch, screwdriver, square, cutter, small steel ruler, ruler plate, line drop, ink bucket and so on.
3. Relevant conditions of construction operation.
3.1 wooden bricks or iron pieces shall be pre-embedded at the structural plane and through the beam at the entrance of the wooden wallboard.
3.2 the skeleton installation of the wooden wallboard should be carried out after installing the door window and windowsill board, and the nailing panel should be carried out after plastering the wall and the ground.
3.3 the drying of wood shall meet the prescribed moisture content, and the keel of the retaining wall shall be brushed with preservatives after planing.
4. Construction process:
5. Construction technical measures:
5.1 locating and springline: the elevation, plane position and vertical dimension of the wooden wallboard should be found in advance according to the requirements of the design atlas before installation.
5.2 check the embedded parts and holes: check whether the embedded parts, bricks or wedges meet the design requirements, and whether the spacing size and position meet the requirements of the fastening keel; measure whether the dimensions of doors, windows and holes are square, vertical and in line with the design requirements.
5.3 laying and coating moisture-proof layer: the wooden parapet wall and the wooden keel must be found and straightened when the design is moistureproof, the gap between the skeleton and the wooden brick should be padded with wood mat, each wooden brick should be nailed down with at least 2 nails, and the plate thickness should be reserved when the keel is nailed. The contact surface between the wooden keel and the wall shall be treated with anticorrosion, and the other three sides shall be treated with fireproof paint not less than three times.
Installation: after the keel installation, check the qualified installation of 15mm thick Blockboard as lining board, requiring the lining board to be nailed firmly, the fixed spacing of nails controlled in 200mm or so, the back brush fireproof paint, and the expansion gap between splicing boards should be reserved around 5mm to ensure the expansion of temperature changes.
5.5 installation panel:
Panel color selection pattern: before the panel comes into use, it is selected according to the dosage of the same room and adjacent parts, which is consistent with the wood grain and color after installation. Cutting board preparation: according to the keel ruler, larger than the keel spacing for cutting the board, according to the large surface should be clean (glued board is strictly prohibited side net), small face scraped straight. When preparing the long butt joint of the panel, it must be considered that the joint is located at the transverse brace, and the back of the plate should be made with a unloading groove to prevent the plate from twisting and deformation. generally, the spacing of the unloading groove is 100mm, the groove width is 10mm, and the groove depth is 6-8mm.
Panel installation: check the keel position, flatness, fastness of nailing, moisture-proof layer and other structural requirements before panel installation, and install after qualified; after the panel is equipped, the panel size, seam and joint structure are completely suitable, and only when the wood grain direction and color look and feel are good, can the formal installation be carried out. Panel joint installation should be glued and keel nailed firmly, nailed panel nail specifications should be appropriate, nail length of about 2-2.5 times the thickness of the panel, nail spacing is generally 100mm, nail cap should be smashed flat, and punch the nail cap along the wood grain direction into the panel 1-2mm; nail affixed to the face: paste material should be selected, pattern, color should be similar to frame material, panel. The size and thickness of the face should be the same, and the succession should be smooth and correct.
6. Quality standard
6.1 guarantee Project:
(1) Tree species, material grades, varieties of plywood, moisture content of wood, anticorrosion and fire prevention measures must comply with design requirements and construction codes.
(2) Blockwork and base or wood brick nails must be firm and not loose.
6.2 General projects
(1) production: correct size, straight and smooth surface, square edges, straight lines, no nail cap, no planer, plane mark, burr and hammer mark.
(2) installation: the position is correct, the cutting angle is neat, the intersection circle and seam are tight, straight and smooth, close to the wall, and the size of the wall is the same. Wood parapet wall, wooden tube board, face facing installation allowable deviation.
6.3 allowable deviation item item allowable deviation (mm) test method 1 upper mouth straight 3 pull 5m line ruler inspection 2 vertical 2 hanging wire drop ruler inspection 3 surface leveling 1.51m ruler inspection 4 seam strip spacing 2 foot inspection
7. Protection measures for finished products
7.1 after entering the market, the fine wood products should be stored in the indoor warehouse or shed, keep them dry, ventilated, and install the types and specifications of the products and store them horizontally. It is generally required to seal the varnish after passing the entrance inspection to ensure that the decorative panel will not be deformed.
7.2 batching shall be carried out on the operating platform, and the finished product shall not be operated directly on the ground without protective measures.
7.3 the protective cushion should be laid on the windowsill during the installation of the window cover. Do not stand directly on the windowsill to operate.
7.4 during the installation of the wallboard, a primer should be applied to prevent dryness or contamination.
7.5 in order to protect the finished products of cabinets from damage or pollution, especially at the entrances and exits, protective measures should be taken in time, such as installation of protective strips, corner plates, rubber film, special care, etc.
8. quality problems that should be paid attention to in construction.
Analysis of the causes of quality problems after installation, there are irregular patterns, uneven colors, uneven edges and corners, uneven surface, black lines at seams and lax seams, or pressing top strips of different thickness, uneven heights, crackles, etc., tube board, face plate cutting angle is not strict, not square.
The panel material is mixed, and the color and flowers are not matched before installation; when the glue of the plywood surface is permeated or pasted, the residual glue of the seam is not cleared, the black pattern will appear on the varnish. The door and window frame is not cut or slotted, so that the front of the tube board is directly affixed to the back of the door and window frame, which can not cover the gap, resulting in lax combination. The cross section of the top strip of the wooden wall skirt is small, and it is difficult to process it on the spot, or although the finished product is purchased, it is not selected, resulting in uneven thickness. At the same time, because the cross section of the pressing strip is too small, it is easy to nail when nailing. The 45 °angle of the tube board and the face is not cut accurately, and the fine planing or sandpaper brake is not used after sawing, resulting in lax and irregular cutting angles.
The moisture content of panel material should not be more than 12%. The thickness of plywood (slice or rotary) should not be less than 5mm, when thick wood is required to be mosaic, the thickness should be less than 15mm; when not required, the thickness should be not less than 10mm, but the back must be provided with deformation groove. The width of Qikou plate should not be greater than 100mm. The surface plate material should have a straight texture, uniform color and similar pattern. Sticking face strips requires clear and straight lines. When slicing is selected, try to align the pattern wood core. Generally large patterns are installed below; small patterns are installed on top to prevent inversion. The good color is used in the head-on, and the worse color is used in the lower back. The seam width between each grid of the surface layer is about 8mm. Metal strips can be added when the requirements are high. The longitudinal joint of the wooden parapet wall should be made at the top of the window or below the windowsill to avoid the sensitive range of line of sight. The panel should be designed to find straight adjustment before installation, and then formally installed. The top of the wooden wall skirt should be stretched and leveled. The wood crimping strip should be nailed together with the same thickness and similar color, and the shade angle joint adopts the connection method of 45 °upper part and lower half flat roof.
Surface layer bright nail defect: the hardwood decoration nail hole is too big. Face sticking, seam pressing, wall skirt top line and other end crackling and nail cap exposure and so on.
The nail cap is not flat enough, or the flat nail cap is nailed in across the wood grain. The iron punch is too thick or deviated. There is no wooden drill in front of the nail. At the seam of the panel, the large nail cap on the keel below should be smaller than the diameter of the nail, and the flat nail cap should lie in along the wood grain. The position of the nail should be nailed between two wooden tendons. The iron punch should be conical, not too sharp, but should be smaller than the nail cap. The nail cap rushes into the 1mm under the board. The panel wood is hard, so you should first use a wooden drill to draw a small eye, and then nail it. In the part of the nail, the nail should be raised, and the crackle should be glued with glue. After being consolidated, a wooden drill should be used to draw small eyes on both sides of the crack and fix it firmly. A large nail cap is exposed on the keel of the panel seam, which can be washed into the 10mm with an iron punch, and then patched with the same wood viscose.
