Description

Technical Field

[0001] The invention relates to the field of building structures, in particular to a connecting device for a corrugated steel plate enclosure structure and a prefabricated concrete column. Background Art

[0002] Traditional precast concrete columns are mostly used in frame structure factories, and the outer wall enclosure structure of the frame structure is generally designed as a brick wall. Due to the functional characteristics of the frame structure, the precast concrete columns are set up in large sizes in height and span. Therefore, the traditional brick wall maintenance structure has the following disadvantages: First, a large number of ring beams and structural columns need to be added to ensure the overall stability of the wall, and the construction process is cumbersome; second, during construction, double rows of ground scaffolding need to be set up on both sides of the wall to provide a construction work surface and a construction material stacking area, and the working environment is dangerous and complicated; third, vertical transportation of construction materials is troublesome and the work efficiency is low; fourth, the overall construction economic benefits are poor. The corrugated steel plate maintenance structure has the characteristics of convenient construction, short cycle, high degree of mechanization, beautiful appearance, and low construction cost. Since the traditional precast columns are not equipped with embedded plates and other connectors, it is imperative to invent a connection device between the corrugated steel plate enclosure structure and the concrete precast column. Summary of the invention

[0003] In view of the above situation, in order to solve the defects of the prior art, the purpose of the present invention is to provide a connection device between a corrugated steel plate enclosure structure and a precast concrete column, which can effectively solve the problems of the prior art such as dangerous and complex working environment, low work efficiency and poor overall construction economic benefits.

[0004] The technical solution solved by the present invention is to include a hoop and a purlin support plate. The hoop is composed of a support member, two connecting members and a backing member. Connecting plates are welded at both ends of the connecting member. The support member and the backing member are fixedly connected together by connecting bolts to form a rectangular hoop to surround the concrete column. A purlin support plate that is clamped on and parallel to a side plate is welded between the two side plates of the support member, and purlins are fixedly connected to the purlin support plate.

[0005] The present invention has a simple structure, reasonable design, easy manufacture, high operability and low construction cost. It effectively solves the connection problem between concrete columns and corrugated steel plate maintenance structures. Hoops are installed on traditional concrete columns, and the number and positions of the hoops are arranged according to design specifications and usage requirements. It is an innovation in the connection device between the corrugated steel plate enclosure structure and the precast concrete column. BRIEF DESCRIPTION OF THE DRAWINGS

Connecting plates 2-1 are welded at both ends of the connecting member 2. The support member 1 and the backing member 3 are fixedly connected together by connecting bolts 4 to form a rectangular hoop surrounding the concrete column 6. A purlin support plate 5 clamped on and parallel to one side plate is welded between the two side plates of the support member 1, and a purlin 7 is fixedly connected to the purlin support plate 5.

[0016] In order to ensure the use effect, the support member 1 is provided with first elongated bolt holes 1-1 at both ends of the side plates perpendicular to the purlin support plate 5, and the support member 1 is fixedly connected with the connecting member 2 through the connecting bolts 4 passing through the first elongated bolt holes 1-1.

[0017] The connecting plate 2 - 1 is provided with a circular bolt hole, and is fixedly connected to the supporting member 1 and the backing member 3 by connecting bolts 4 passing through the circular bolt holes.

[0018] The backing member 3 is provided with second elongated bolt holes 3-1 at both ends of one side plate, and is fixedly connected to the connecting member 2 by connecting bolts 4 passing through the second elongated bolt holes 3-1.

[0019] The length of the connecting member 2 is shorter than the cross-sectional length of the concrete column 6 .

[0020] The support member 1, the connecting member 2 and the backing member 3 are all L-shaped steels or angle steels or channel steels formed by splicing two steel plates into one body.

[0021] The purlin supporting plate 5 is provided with purlin mounting bolt holes 5 - 1 , and the purlin 7 is fixedly connected to the purlin supporting plate 5 via connecting bolts 5 - 2 passing through the bolt holes 5 - 1 .

[0022] The purlin support plate 5 is formed by welding a rectangular steel plate and a triangular steel plate perpendicular to the rectangular steel plate. The triangular steel plate is provided with a rectangular groove that is clamped on a side plate of the support member 1.

[0023] There are at least four purlin mounting bolt holes 5-1 symmetrically arranged.

[0024] The use of the present invention is to make a rectangular hoop with steel plates, angle steels or channel steels, the hoop is connected to the precast concrete column 6, the purlin support plate 5 is welded on the hoop, and finally the corrugated steel plate maintenance structure is connected to the purlin support plate 5 on the hoop through the purlin 7 to complete the construction. The hoop 5 is connected to the precast concrete column 6 through friction, and the size of the friction force is adjusted by the connecting bolts 4 and the connecting parts 2. The size of the steel plate, angle steel or channel steel used in the hoop can be verified and adjusted according to the weight of the corrugated steel plate maintenance structure. The spacing between the hoop meets the design requirements and can also be adjusted according to the size and position of the windows and door openings.
