What is the method of Chinese ceiling construction

One, group lattice cement lattice

Group lattice cement lattice can be assembled by single or multiple lattice elements.

The installation method of group lattice is as follows:

1.Measurement and pre-arranging. Field measurement of the proposed installation of lattice parts and the actual size of the lattice, and then pre-arranged according to the design pattern, adjust the seam.

2. Pulling line, positioning. According to the position of the lattice after adjusting the seam vertical and horizontal line, with a level ruler and line hammer verification, to achieve horizontal and vertical, in order to ensure that the position of the lattice is accurate.

3. Splicing, anchoring. With 1:2 cement mortar bottom-up lattice masonry block by block, adjacent lattice blocks with steel pins inserted into the diameter of 16-20mm holes, and then cement mortar solid, the whole piece of lattice around the wall, columns, beams, should be firmly connected through the anchors.

4. Surface finishing. In addition to brushed stone, terrazzo lattice without finishing, other cement products lattice spelling, anchoring is completed, according to the design requirements of paint.

Two, precast concrete vertical lattice

Precast concrete vertical lattice by the upper and lower ends of the beams (slabs) fixed to the ground and the prefabricated reinforced concrete vertical boards and installed between the vertical boards of the flower decorations.

Precast concrete vertical lattice installation method is as follows:

1. Anchor preparation. Structure construction should be based on the vertical board interval size of pre-buried iron or reserved groove, if the vertical board is ready to insert between the flower decorations, must also be pre-buried in the board anchors or leave a groove. If the design is fastened with expansion bolts or nails, it is not necessary to bury the pieces and leave grooves during the construction of the structure.

2. In the upper and lower structural surface pop-up vertical board in place control line, the vertical board in the installation position, with the line drop hanging straight and temporarily fixed, upper and lower ends according to the design of the anchoring method to determine the firm connection.

3. Insert flower decoration. According to the design elevation pull horizontal line, according to the line to install the vertical board between the decoration. Connection can be used to insert bar connection, screw connection or welding, etc., but if the use of decorative pre-bar inserted into the groove of the connection method, the middle of the decoration should be in place at the same time with the vertical board.

4.hook seam coating. The gap between the vertical board and the main structure, the gap between the flower decoration and the vertical board with 1:2-1:2.5 cement mortar hook solid, and then according to the design requirements of the paint.

Three, wood lattice

1. Anchoring preparation. Structural construction, according to the design requirements in the wall, columns, beams and other parts of the wall, accurately buried wood brick or metal pre-embedded parts.

2. Workshop pre-installation. Small wood lattice should be pre-assembled in the carpentry shop; large wood lattice should also try to improve the degree of pre-assembly, reduce the site production process. The wood should be dried as required.

3. On-site installation. Wooden lattice assembly should be mortise and tenon joints to ensure that the gap is tight. If connected with metal parts, must be surface treatment, screw caps and iron parts shall not be exposed.

4. sanding and finishing. After installation, the surface scraping putty, sandpaper polishing, painting.
