Diagonal Bracing Reinforced Steel Frame-Shear Wall Assembled Large-Space Residential System

Abstract

The present invention provides a large-space residential system with reinforced steel frame-shear wall assembled by diagonal bracing, which is composed of a vertical stress system and a horizontal stress system. The cast-in-place shear wall at the position of the household wall and the integrated exterior wall including the steel frame structure with diagonal braces, the horizontal stress system is the SPD floor. The residential system of the present invention breaks through the shortcomings of the traditional shear wall structure with many internal load-bearing walls and limited functional layout of the building space. The large space of changing room type greatly reduces the number of prefabricated components, which facilitates the standardized design, production and construction of prefabricated components. Reduce the cost of component manufacturing, realize engineering applications, and promote the development of prefabricated housing in China.

Description

technical field [0001] The invention relates to a prefabricated residential system, in particular to a steel frame-shear wall prefabricated large-space residential system. Background technique [0002] At present, although the country is making unprecedented efforts to promote industrialized housing, the results are still insignificant, and there is a huge contrast between the results and the goals: the goal is to give full play to the advantages of high efficiency and low cost in industrialized production, improve construction efficiency, and reduce material consumption and construction costs; the result is that the construction process Significant increase, the degree of mechanization of component manufacturing is not high, the consumption of materials increases instead of falling, and the construction cost increases significantly.

[0002] At present, although the country is making unprecedented efforts to promote industrialized housing, the results are still insignificant, and there is a huge contrast between the results and the goals: the goal is to give full play to the advantages of high efficiency and low cost in industrialized production, improve construction efficiency, and reduce material consumption and construction costs; the result is that the construction process Significant increase, the degree of mechanization of component manufacturing is not high, material consumption increases instead of falling, and construction costs increase significantly

Judging from the current status of the development of prefabricated residential buildings, there are still the following problems: 1) The design has not yet been standardized and modularized. Only when the design is standardized and modularized can the standardization of components and the development of industrialization of production be driven; 2) There are many prefabricated building systems, and a relatively complete and unified standard system has not yet been formed; 3) The components have not yet formed industrialized production, and the production of components has not achieved mass, assembly line, and mechanized production, but only the manual work on site. The manual operation and labor-intensive production characteristics have not been significantly improved. On the contrary, due to the increase in the production, transportation and installation links, the construction cost has been significantly increased, resulting in insurmountable contradictions; 4) Insufficient production capacity of prefabricated components, especially instantaneous production capacity Insufficient, there is no standardized product in China's real estate market, which belongs to private customization, and the instantaneous production capacity of components is insufficient; 5) The level of construction mechanization is not enough. Most of the current prefabricated structures are partially prefabricated, and the combination of prefabrication and cast-in-place cannot be avoided. It is still necessary to improve the level of construction mechanization and reduce the complexity of on-site construction technology and construction quality problems caused by dry and wet cross operations; 6) The cost is high, and the current cost of prefabricated buildings is higher than that of cast-in-place structures

However, such structural systems (especially high-rise residential buildings) often have small building bays, which is not conducive to sustainable utilization such as post-construction renovations, and cannot meet the individual needs of residential use.

In addition, when designing and constructing high-rise shear wall structure residences in an industrialized way, it often encounters low standardization of prefabricated components (building flat and many types of facades), high component production costs (low mold utilization rate), and difficult installation (sets) The number of cylinder connections is much larger than that of the frame structure) and other issues
