Bookcase construction process and acceptance

First, the bookcase production process

Bookcase: There should be enough space above the bookcase. Put some small books and big books (some newspapers and pictures are bigger). According to your own habits, make sure the computer's keyboard is on the desktop or keyboard drawer?

1. If the length and height of the cabinet exceeds 2.4m, the horizontal plate of the vertical plate is overlapped with the two plates of the nine plates to ensure the consistency with the thickness of the large core plate.

2, the open structure board with a plane to the edge planing, and use sandpaper to get rid of burrs, in accordance with the drawings do a good job, with the code nails will be nine plywood nail back board (except for special circumstances).

3, when the cabinet line shuts the mouth and the side veneer, should pay attention to the height of the veneer on both sides of the cabinet and the height of several facing lines shuts the mouth to be consistent, in order to avoid from the side of the cabinet to have the height difference

4. The door frame is made of high-quality nine-kilo board 60mm strips with double-sided dislocations and the distance between the grooves is 150mm. The horizontal clearance distance of the nine PCT board is 200mm, and its interface gap is not more than 1mm. The two-sided slats shall be coated on both sides with opal white glue. Where the above conditions are not met, the woodworking class shall compensate the material.

5, door double-sided oil colored paint, double-sided pressure two-story plywood, no lines closed mouth.

6, the door outside the oil varnish, the outer side of the embossed panel and the three plywood, pressure inside the two-story plywood, outside the brush varnish, brush inside the paint (paste the glassy film after the internal varnish and then paste). Cover with lines.

7. The cabinet door is made of middle-inlaid glass, and paint is sprayed inside and outside. The inner and outer sides are hollowed out with the entire plywood.

8. The glass is embedded in the middle of the cabinet door, and the outer side is varnished. Then, the exterior panel and the three-plywood are used, and the inner surface is pressed by two-layer plywood (except for special design requirements).

9. Pressing and placing of the cabinet door: The cabinet door should be placed on a prefabricated platform, and the external pressure should be more than 100kg and the force should be even (you can consider using a simple fixture), and then turn over and press again in 3 days. The pressing time is 7 days or more in summer and 10 days or more in winter. On the lower bar, it indicates the time of pressing and flanging, and the door of the cabinet after pressing is not allowed to be tilted, and it must not be damped to avoid deformation.

10. When the cabinet is used as the partition wall, the back plate is made of nine plywood. The back of the cabinet must be made of 20 x 40mm wood to form a dragon frame with an interval of 300 x 300mm, and then the plasterboard should be flatly attached to the keel to fix the cabinet. The joints of the backboard must be misaligned with the gypsum board joints, unless otherwise required by the design (silica wool should be added) to ensure the protection against cracking and sound insulation

11, drawer practice: drawer with high quality 15 centigrade core board to do the box, 600 x 600 or less 5 plywood to do the floor (large with nine percent board to do the floor), 15 white wood line spell angle to receive four border mouth, with a large core board plus The veneer panel is used for the drawer surface (the seam cannot be seen on the side, and the seam between the drawer panel and the cabinet frame does not exceed 1mm). The varnish type closes with the corresponding line, the paint type does not need to close the line, the drawer width should be 25mm narrower than the structure, use three silent drawer rails, install with φ3×12 self-tapping screws, 12 drawers per drawer. If the drawer is a drawer in the cabinet door, the height is not increased below 30mm, no magnetic touch can be installed, the carpentry workshop is reworked, and the compensation material is provided. Before the acceptance of each drawer, the ash on the drawer track should be cleared and a little oil should be added to ensure the push and pull flexibility.
