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. The technical requirements are very high; in addition, the prestressing purpose of the joint 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: 2110", 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 method of the "IMS" system, or at least it shows that it is not a perfect structural form, and it is an implementation technology that has not passed national approval; in application, it is difficult to construct on site—that is, it is not suitable for industrial construction and the cost is high. The production and implementation of standards that are not suitable for the market economy have been hindered, resulting in not many applications in the past 20 or 30 years.
[0006] (2) At present, the division and connection nodes of prefabricated floor slabs have the methods in the published patents ZL201722392098.3 and ZL2017111850923. Although it solves the principle of dividing and designing large assembly slab-column structures, it is difficult for prefabricated components and connection nodes and assembly sites In terms of construction, it is a conventional practice, with shortcomings, requiring a lot of support and installing formwork

Abstract

The invention discloses a plate-column structure assembly system, including column cap connecting plates with floor prefabricated components, no column cap connecting plates with floor prefabricated components, prefabricated column caps or pallets, columns, and connection nodes. The prefabricated column caps or pallets are inserted into the top of the columns. The end of length direction of the column cap connecting plates with floor prefabricated components is connected or shelved at the edge of the prefabricated column caps or pallets. The edge of the no column cap connecting plates with floor prefabricated components is directly shelved on the laminated layer which is on the side of the column cap connecting plates with floor prefabricated components. After the column cap connecting plates with floor prefabricated components, the no column cap connecting plates with floor prefabricated components, the prefabricated column caps or pallets and the joint surface of column top are formed, pouring concrete pouring trough and splicing into a whole closed slab bottom plane, an integral floor structure is formed through connection nodes. The plate-column structure assembly system also discloses floor prefabricated components and construction methods. The plate-column structure assembly system and floor prefabricated components and construction methods can reduce the support and template installation.

Description

technical field [0001] The invention relates to the field of concrete structures and prefabricated building structures, in particular to a slab-column structure assembly system, floor prefabricated components and a construction method. 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; The floor height is very economical in underground buildings and as multi-storey parking. The slab-column structure can be cast on site or prefabricated, and will have a large market space. [0003] Dismantling the building structure into components and assembly construction that can be factory produced, transported, easy to install, safe, reliable and economically reasonable is the key to the industrialization of construction - the prefabricated building. [0004] At present, ...
