Assembled type steel frame concrete box type unit structure system and construction method thereof

Abstract

The invention discloses an assembled type steel frame concrete box type unit structure system and a construction method thereof. The structure system comprises a foundation and an overground structure connected with the foundation; the overground structure comprises at least an upper-layer structure and a lower-layer structure which are vertically spliced through a steel frame; the steel frame is a groove-type horizontal steel frame which is preset on the spliced position of upper-layer and lower-layer wall face components and is embedded along the inner side of the bottom of the upper-layer wall face component in a through mode; a bottom vertical throwing rib of the upper-layer wall face component penetrates through the steel frame to be fastened through an upper flange plate sleeve; and a top vertical throwing rib of the lower-layer wall face component penetrates through the steel frame to be fastened through a lower flange plate sleeve. Box-type structure units of each layer of structure are connected into a whole in a mortise-tenon joint mode. The construction method of the structure system comprises the steps of designing and prefabricating of the box-type structure units, conveying of the box-type structure units to a site to be connected with a cast-in-situ part, connection between the box-type structure units, and the like. The assembly level of a building structure is improved, detachable connection is achieved, the construction speed is increased, and the wet construction on the site is reduced.

Description

technical field [0001] The invention belongs to the field of building structure systems, in particular to an assembled steel frame concrete box structure system and a construction method thereof. Background technique [0002] At this stage, our country has entered the 13th Five-Year Plan, and environmental and energy issues have become increasingly prominent, which has threatened our future generations. As a traditional industry in my country, residential construction has been in the extensive production stage for a long time, and the consumption of energy and raw materials is too large. Now, the construction method of prefabricated concrete structure is used to solve the problem of low industrialization, low labor productivity and low technical content of traditional cast-in-place construction methods. , Single structural form, poor building quality and functions, especially the seismic safety and comfort of residential structures need to be improved. However, the existing ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a prefabricated steel frame concrete box-type unit structure system and its construction method, to solve the problem that the existing prefabricated concrete structure system has relatively many wet operations on site, and the connection can only be installed without damage to the structure. It also solves the technical problems of dismantling under the circumstances of the existing prefabricated concrete structure, which has a single function of the building's functional partition, the insulation layer needs to be constructed separately, the energy saving efficiency is low, the double walls between adjacent boxes waste materials, and the joints of the structure Technical problems that cannot guarantee tightness
