Assembled type hollow grid plate floor system

Abstract

The invention discloses an assembled-type hollow grid plate floor system. The assembled-type hollow grid plate floor system is characterized in that the floor system structure comprises shearing force prefabricated components (1) and prefabricated slabs (2); the shearing force prefabricated components (1) are connected and fixed with each other to form a shear key (3) grid rib; the shearing force prefabricated components (1) comprise shear keys (3) and lower rib branches (4); the shear keys (3) are vertically arranged; one end of each lower rib branch (4) is connected with the lower part of each shear key to form an integral body; the end part of the other end of the lower rib branch (4) is provided with a connection reserving device (5); the lower rib branches (4) of the shearing force prefabricated components (1) connect with each other through the connection reserving devices (5); the prefabricated slabs (2) are alternatively arranged; four corners of the prefabricated slabs (2) are fixed on the shear keys (3) of the shearing force prefabricated components (1) respectively; and the gaps between the prefabricated slabs (2) are sealed by cast-in-situ concrete grouting. The assembled-type hollow grid plate floor system has a very important role to the safety control of architectural structure; and the structure is not immediately damaged when a geological disaster, for example, an earthquake which exceeds intensity of design grade happens, so that people have enough time to be transferred.

Description

[technical field] [0001] The invention relates to a prefabricated floor, especially an assembled hollow grid plate floor. [Background technique] [0002] With the rapid development of my country's economic construction, most of the public and industrial buildings in the basic construction have a span of 18m ~ 30m, and the load is 3kN / m 2 ~5kN / m 2 The vast majority of these buildings are single-storey, and more than 90% of these buildings are single-storey, which takes up a lot of land and also reduces the area of ​​forests and green areas year by year. Why not use long-span multi-storey buildings? The key lies in long-span buildings. How can the cover structure meet the technical requirements of "safety, rationality, opportunity and economy". With the rapid increase in the unit price per mu of land, it is not only expensive to rebuild a single floor. From the analysis of the rational use of land resources in my country, the research and development of new floor structures ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a new floor structure technology for multi-storey and large-span public and industrial buildings, so as to solve the problem of "too high building cost" that has plagued engineers and users for a long time. Multi-storey long-span buildings find a new structure with simple construction, low cost, and can save a lot of urban construction land
