3 operating process
3.1 Process flow:
Line positioning → check embedded parts and holes → spread coating moisture-proof layer → keel preparation and installation → binding panel
3.2 to find and crossed: wooden retaining wall, wooden child board installation, should be based on the design requirements, first find a good elevation, plane position, vertical size, the shell line.
3.3 Check the embedded parts and holes: After the bomb line check embedded parts, wood bricks are in line with the design and installation requirements, the main check arrangement spacing, size, location, meet the requirements of the staple keel; measurement of doors and windows and other hole location, Whether the size is Founder vertical, and design requirements are consistent.
3.4 Shop, coated with moisture-proof layer: the design of moisture-proof wooden retaining wall, wooden sub-board, the keel in the staple should be pressing the moisture-proof membrane, or in the staple before bunched damp layer construction.
3.5 keel preparation and installation:
3.5.1 Wood-framed keel:
3.5.1.1 Partial wood-framed keel: According to the size and height of the room, can be made into a dragon skeleton, the whole or sub-block installation.
3.5.1.2 full-height wood keel: first measure the size of the room, according to the four corners of the room and the location of the upper and lower keel, the four-frame keel to find bits, flat stapled, straight, and then keel spacing required by the design staple keel.
When the design element requirements, the general cross-keel spacing of 400mm, vertical keel spacing of 500mm. If the panel thickness of 15mm or more, the horizontal keel spacing can be expanded to 450mm.
Wood keel installation must find the side, looking straight, the gap between the skeleton and wooden bricks should be padded with wooden mats, each wooden pad with at least two nails nailed in the installation of the keel reserve when the published surface thickness.
3.5.2 Wood Cylinder Keel: According to the actual size of the hole, according to the design specifications of the cross-section of the skeleton material, one side of the bobbin skeleton can be divided into three prefabricated, one roof, one on each side. Each piece is generally two pole, when the cheese board width is greater than 500mm, the middle should be appropriate to increase pole. Transverse keel spacing of not more than 400mm; panel width of 500mm, the horizontal keel spacing of not more than 300mm. The keel must be securely fastened to the fixture and the surface should be flattened and flat, straight, and straight after installation. Preservative preparation and brushing methods should be consistent with the provisions of the relevant norms.
3.6 Stapling Panel:
3.6.1 panel color selection with grain: all approach the panel material, press the same room before use. Near the site of the amount of selection, so that after installation from the perception of grainy, color similar to the same.
3.6.2 Preparation of the cutting board: According to the rule of the keel, cut the board on the board, the original wood surface should be planed; the plywood and plywood should be planed and the facets should be shaved. When the panel is long-butted, it must be considered that the joint is located at the horizontal keel.
The back of the original timber panel should be done unloading slot, the general unloading force groove spacing of 100mm, slot width 10mm, groove depth of 4 ~ 6mm, to prevent distortion of the board surface.
3.6.3 Panel Mounting:
3.6.3.1 Before installing the panel, check the keel position, flatness, nail set, moisture proof construction requirements, etc., after installation.
3.6.3.2 After the panel is equipped with the test equipment, the size of the panel, the joint and the joint are completely suitable for construction, and the wood grain direction and color perception can still be installed.
3.6.3.3 Panel joints should be coated with glue and keel nail, solid nail panel specifications should be appropriate, nail length of about 2 to 2.5 times the thickness of the panel, nail from the general 100mm, nail cap should be smashed flat, and with the sharp red Sub-needle will be directed into the direction of the wood grain plate surface l ~ 2mm.
3.6.3.4 nail paste face: paste face material should be selected, pattern, color and frame material, panel approximation. Face size specifications, width, thickness should be consistent, then Gui-ping should be no error Cha.
