Assembled board-column structure floor slab, dividing method thereof, and floor slab unit components

Abstract

The invention discloses an assembled board-column structure floor slab, a dividing method thereof, and floor slab unit components. The assembled board-column structure floor slab comprises the multiple prefabricated floor slab unit components comprising adjacent column connection board belts, or the assembled board-column structure floor slab comprises the multiple prefabricated floor slab unit components comprising the adjacent column connection board belts, and the multiple conventional prefabricated floor slab unit components. The adjacent column connection board belts in the prefabricated floor slab unit components comprising the adjacent column connection board belts are long-strip-shaped belt boards integrally stretching across every two adjacent columns. The connection line of section centroids of the two adjacent structure columns connected through each adjacent column connection board belt serves as a reference line of the adjacent column connection board belt, and the width of each adjacent column connection board belt is larger than or equal to the longest side length of the connection sides of the two adjacent structure columns connected through the adjacent column connection board belt. The adjacent column connection board belts are provided with direct-through bottom reinforcing bars in the span direction. By the adoption of the technical scheme, cost can be reduced, construction is convenient, and safety and reliability of the board-column structure of the prefabricated floor slab can be improved at the same time.

Description

technical field [0001] The invention relates to a prefabricated assembled concrete structure and a method in the field of building industrialization, in particular to an assembled slab-column structure floor, a division method thereof, and a floor unit component. Background technique [0002] Since prefabricated buildings conform to the production method of environmental protection and energy saving, the country has proposed a development goal of making prefabricated buildings account for 30% of new buildings in about 10 years; It has the advantages of reducing the storey height, and has good economy in underground buildings and multi-storey parking garages. If the slab-column structure can be prefabricated, it will also have a large market space. [0003] Dismantling the building structure into components that can be produced in factories, transported, and installed easily, and that are safe, reliable, and economically reasonable is the key first step in the industrializati...

Problems solved by technology

In this form, the compressive stress of the friction force comes from the post-tensioned prestressed steel strands on site. Because of the special requirements of the connection, the construction process of the prestressed steel strands is cumbersome and difficult, which is very difficult for the construction personnel. The technical requirements are very high; in addition, the prestressing purpose of the node tension is for the connection, and additional stress is generated on the original assembled components, which not only increases the design difficulty but also affects the project cost; and when using the "IMS" system , prestressed friction joints not only need to meet the relevant regulations of reinforced concrete structures, but also meet the requirements of "Technical Regulations for Integral Prestressed Prefabricated Slab-Column Structures CECS52: 2010", which is only an association standard regulation, not a national standard. From On the other hand, it indirectly shows that there are some problems in the connection me
