Straw-steel fabricated wall connection device and connection node method

Abstract

The invention relates to a straw-steel fabricated wall connecting device and a connecting joint manufacturing method. At present, demands of people for office buildings and housings are increased yearby year, the form of construction is mostly reinforced concrete, the construction process is cumbersome, the destructiveness is high, and demolition objects are difficult to reuse. The straw-steel fabricated wall connecting device comprises a fabricated wall (11). The fabricated wall is divided into a left side wall body (1) and a right side wall body (2). The left side wall body is welded to twosliding self-locking structures. The right side wall body is welded to three sliding self-locking structures (3). The middles of the left side wall body and the right side wall body are provided withgrooves A (7) and convex parts A (8). The interior of each sliding self-locking structure is provided with sliding hollow metal (4). The side edge of each sliding hollow metal is provided with a sliding way (5) and a groove B (6). The upper edge of each sliding hollow metal is provided with a convex part B (12).

Description

Technical field: [0001] The invention relates to a straw-steel assembled wall connection device and a connection node method. Background technique: [0002] With the development of the times and the progress of society, people's demand for office buildings and residences is also increasing year by year. At present, most of the buildings are in the form of reinforced concrete, but this traditional structure requires a lot of manpower and material resources for construction. At the same time, the construction process is relatively cumbersome, and most of the demolition is based on blasting, which is relatively destructive. It is difficult to reuse the demolished objects, and the waste of resources is serious. Therefore, new prefabricated structures emerge in due time. Simple and fast, easy to dismantle and recyclable, and many other advantages have emerged and flourished in today's construction industry.

[0002] With the development of the times and the progress of society, people's demand for office buildings and residences is also increasing year by year. At present, most of the buildings are in the form of reinforced concrete, but this traditional structure requires a lot of manpower and material resources for construction. At the same time, the construction process is relatively cumbersome, and most of the demolition is based on blasting, which is relatively destructive. It is difficult to reuse the demolished objects, and the waste of resources is serious. Therefore, new prefabricated structures emerge in due time. Simple and fast, easy to dismantle and recyclable, and many other advantages have emerged and flourished in today's construction industry

[0003] Although the development of prefabricated walls is very rapid at present, there is still the problem that the wall and the overall structure cannot form a unified system, and the main reason is that the joint connection method is not reasonable enough. Most of the current joints are connected by bolts, welding Such forms not only make the splicing operation more complicated, but also its stability, seismic performance, and integrity are not good enough, which can easily cause problems such as cracking and deformation of the prefabricated wall. At the same time, the existing node connection form is difficult to apply to high-rise buildings.

[0004] The splicing of current prefabricated buildings not only includes horizontal ordinary splicing, but also L-shaped, cross-shaped, and T-shaped splicing. The traditional method is mostly to use transfer components and bolts to connect. However, the integrity of the wall, earthquake resistance, stability and other performances are poor, and it is still not suitable for buildings with high strength requirements.
