Construction Method of Prefabricated Steel Tube Concrete Frame-Shear Wall Structural System

Abstract

The invention discloses a construction method of a prefabricated concrete filled steel tubular frame-shear wall structure system. The construction method comprises the steps that firstly, required components are prefabricated, a foundation is processed and the foundation and a ground ring beam are poured according to the design construction drawing requirements; then prefabricated concrete filledsteel tubular frame columns are installed in place, and prefabricated concrete shear wall panels are assembled in a mortise-tenon joint mode; then concrete filled steel tubular beams and the concretefilled steel tubular frame columns are connected according to a proposed method, prefabricated concrete floor slabs are overlapped on the concrete filled steel tubular frame beams, gaps of clamping joints between all the prefabricated parts and a wall are filled with foamed neoprene in a sealing mode; and finally, a structure of which the concrete filled steel tubular beams and columns are wrappedwith the wall is formed, and excellent integrity is achieved. The construction method of the prefabricated concrete filled steel tubular frame-shear wall structure system integrates the advantages ofa concrete filled steel tubular structure and a shear wall structure, realizes building industrialization and green construction, is beneficial to reducing construction cost, improving construction efficiency, reducing material consumption and reducing environmental pollution, and provides guarantee for the green construction.

Description

technical field [0001] The invention belongs to the research field of building industrialization technology, and in particular relates to a construction technology of an integrally assembled steel pipe concrete frame structure, which is suitable for buildings such as low-storey buildings and large-span industrial plants. Background technique [0002] The industrialization of construction refers to the process of transforming the traditional construction production mode into an industrialized production mode. Its basic connotation is based on the concept of green development, supported by technological progress, and information management. The whole process of project design, development, production and management forms an integrated production chain. Specifically, it is to replace the scattered, low-level, and inefficient handicraft production methods in the traditional construction industry through modern manufacturing, transportation, installation and scientifically manage...

AI Technical Summary

Problems solved by technology

At present, the development hotspots of the industry mainly focus on prefabricated concrete shear wall residences, steel structures and wooden structures. The development of frame structures and other types of prefabricated structures is not balanced, and cannot support the healthy development of the entire precast concrete industry.

At present, most of the domestic prefabricated shear wall houses are connected by bottom vertical reinforcement sleeve grouting or grout anchor lap connection, and the technical treatment of edge components is cast-in-place. There are still few studies on other technical systems, and further research should be strengthened.

[0010] Second, the basic research on prefabricated structures is insufficient

[0011] Third, the support of standards and norms is not enough

Due to the lack of basic research and sufficient engineering practice in the technical standards of construction industrialization, many technical standards are still blank and urgently need to be supplemented.

[0012] Fourth, there are misunderstandings in people's cognition

Since our country has suffered many earthquake disasters in the past two decades, prefabricated houses have caused great losses to people's property in the disaster. Many people mistakenly think that prefabricated houses are prefabricated houses, which makes it difficult to promote prefabricated houses.
