Horizontal joint connecting node of assembled prefabricated structure wallboard unit

Abstract

The invention discloses a horizontal joint connecting node of an assembled prefabricated structure wallboard unit. The horizontal joint connecting node is characterized by comprising an upper end combination surface of a prefabricated structure wallboard unit under a floor, a lower end combination surface of the prefabricated structure wallboard unit on a floor and an end combination surface of aprefabricated horizontal component, which are connected with each other, a conventional rib arranged in a horizontal groove, and an upper end combination surface reserved connecting reinforcement of the prefabricated structure wallboard unit under the floor, a lower end combination surface reserved connecting reinforcement of the prefabricated structure wallboard unit on the floor and a reserved connecting reinforcement of the prefabricated horizontal component, which are connected with each other, and post-cast concrete cast in the horizontal groove; and the post-cast concrete of the horizontal joint connecting node is leveled with or under a floor structure surface. The horizontal joint connecting node has such advantages as convenient scene construction, safety, reliability and the sameperformance of cast-in-place structures, and realizes structural design principles of strong nodes and weak components.

Description

technical field [0001] This invention is a divisional application of an invention patent application with the application number 201610625071.X and the application date on July 29, 2016, and the title is "an assembled prefabricated structural wall panel unit and its connection nodes". Concrete structure, specifically related to the horizontal seam connection nodes of prefabricated structural wall panel units. Background technique [0002] As a structural form in line with industrial production methods, prefabricated concrete structures have the advantages of fast construction speed, low labor intensity, less noise pollution and wet work, and easy control of product quality. Prefabricated building construction can effectively save resources and energy, improve the utilization rate of materials in achieving building energy conservation and structural performance, reduce the number of on-site construction labor, reduce construction waste and reduce the adverse impact of constru...

Problems solved by technology

[0008] (3) The technology of using auxiliary material steel plate or section steel for connection, such as "A Connection Node of Prefabricated Concrete Shear Wall Structure Wall Panel Members" disclosed in the patent document with the authorized announcement number CN 202561554 B, which has a certain length of connection The profiled steel should be placed in the center of a closed rectangular stirrup cage with a spacing of less than 300mm, and the periphery and both ends are hindered by prefabricated components or reserved steel bars, making construction very difficult, and there is no explanation on how to deal with the profiled steel at the intersection of the wall; another example: Authorized announcement number CN 204174785 U's patent literature discloses "a prefabricated wall panel unit upper and lower connection structure", the steel plate connection is a point connection; the two technical solutions disclosed above do not provide the connection method at the edge member of the shear wall, No comprehensive joint connection technology is proposed, nor is the seismic structural principle of "strong joints, weak members"

[0009] (4) There are still some that only solve the local connection technology, and the practicability may be limited by relevant specifications, such as the "U-shaped closed rib connection structure of the horizontal joint of the assembled shear wall structure" disclosed in the patent document of the authorized announcement number CN 102168455 B. Whether the steel bar connection method meets the relevant national regulations on the tension of the steel bar, whether it is seismically resistant, does not provide the connection method at the edge members of the shear wall, and does not achieve the earthquake-resistant building structure principle of "strong nodes, weak members"

[0015] (2) There are only partial connection technologies for node connections, and the seismic design principles of "strong nodes and weak components" are not well realized for connection nodes;

[0016] (3) The connection nodes require the use of section steel auxiliary connection, because entering the section steel structure and adding factors to solve the increase in the connection between the section steel and the concrete structure have to be dealt with, and the production process cannot be truly simplified;

[0017] (4) The on-site construction technology and procedures are not simple enough, and formwork needs to be installed on the post-cast concrete part, which has not realized "complex production factoryization, simple labor on-site activities"

[0018] (5) The connection of prefabricated concrete structures does not achieve the same structural performance as that of cast-in-place concrete structures, which affects the scope of application of prefabricated buildings and severely restricts the promotion of building industrialization to a larger proportion.
