Fabricated integrated large plate

Abstract

The invention provides a fabricated integrated large plate and belongs to the field of fabricated buildings. The fabricated integrated large plate comprises a plurality of vertical precast slabs whichare vertically arranged, and every two adjacent precast slabs are connected through reinforcement. Compared with the prior art, the fabricated integrated large plate is more reasonable, better in intensity rigidity and waterproof effect and more convenient and efficient to manufacture, more materials are saved, and the cost is lower. According to the fabricated integrated large plate, battens arespliced in the vertical direction, for a residence and other buildings with the consistent floor height, a few of battens are used in specification, the production efficiency is high, and the cost islow. A fabricated integrated outer plate spliced through the fabricated integrated large plates can be flat in surface, plastering can be omitted, and therefore materials are saved, the constructionefficiency is high, and the cost is reduced. Further, the fabricated integrated large plates are hoisted together after outer wall decoration is completed in advance in a factory, the construction efficiency and the construction quality can be improved, and the cost is saved.

Description

technical field [0001] The invention belongs to the field of construction engineering, in particular to an assembled integral large slab. Background technique [0002] Prefabricated buildings meet the requirements of building industrialization and green environmental protection, especially the industrial policy of green buildings and building industrialization in my country, and the demand for prefabricated buildings is increasing. Prefabricated panels are one of the main contents of prefabricated buildings. [0003] Existing prefabricated exterior wall panels use slats, assembled large slabs assembled horizontally from prefabricated slats, and prefabricated concrete panels. Wall finish installation. Although the prefabricated exterior wall slats have the advantages of convenient manufacture and low cost, the assembled exterior walls have the disadvantage of cracking and leakage at the assembly joints, and have not been able to be popularized and used in residential and pu...

AI Technical Summary

Problems solved by technology

The technology of document 1 has relatively long upper and lower horizontal plates at the opening. When the length is greater than 1m, the holes reserved for the full-length rib insertion cannot be made by drilling, and only pre-embedded pipes can be used for lath production. The work efficiency is low and the cost is high. Therefore, in practice In use, no full-length ribs will be set in the upper and lower horizontal prefabricated slats of the opening, but this will result in a decrease in the overall structural rigidity (such as figure 1 shown)

[0010] 2. The modulus of the horizontal plate under the hole does not match, resulting in material waste

The standard requirement for the height under the window opening of the building opening is 950mm (900mm from the building surface to the window sill, and 50mm from the structural surface to the building surface), while the national standard specification for prefabricated slats is 600mm wide, using 600+350mm splicing, and the remaining 250mm The materials are difficult to use, resulting in a lot of waste of materials (such as figure 2 shown)

[0011] 3. The cost of upper and lower borders is high

[0012] 4. There are cracks in the board joints, which need to be waterproofed (such as image 3 shown);

[0014] 1. The seam of the splicing board is not glued, and it is easy to crack

[0015] 2. It is necessary to set the upper and lower borders. As mentioned in Document 1, the cost is high, the production is also troublesome, and the efficiency is low

[0016] 3. Setting the window reinforcement holes for filling adhesive can improve the problem of cracking of the panel joints, but the grouting process is complex, it is not easy to ensure full filling, the splicing panel joints are not sealed, and it is easy to leak grout, and the cost is high and the production efficiency is low

[0017] 4. In the case of setting a window hole in the middle of the board, only install the installation frame connected with the window around the hole, the window hole will weaken the strength of the composite wall panel, and the composite wall panel cannot meet the strength requirements, which is unsafe

[0018] 5. There is no solution for the gap in the combination board

In document 3, in order to improve the difficulty of grouting and improve the quality of grouting, multiple pressure grouting holes are set on the plate for multiple grouting, which further reduces the production efficiency

[0021] 2. No technical solution for opening holes or notches
