Description

Technical Field

[0001] This utility model relates to the field of connecting component technology, specifically a high-strength connecting component between steel and concrete structures. Background Technology

[0002] Bolted connections are a common method of connecting steel structures to concrete components. They are characterized by convenient installation, simple construction, and high connection strength. Bolted connections generally use either ordinary bolts or high-strength bolts, the specific choice depending on the engineering design requirements. High-strength expansion bolts are a widely used connection component between steel structures and concrete components. They offer advantages such as high connection strength, simple construction, and wide applicability. The working principle of high-strength expansion bolts involves injecting an expansion agent into a closed channel; the expansion agent gradually expands with increasing pressure, forming a tight bond with the concrete. Welded connections are one of the highest strength connection methods. Their advantages include a simple connection structure and wide applicability. However, welding connections require professional workers and must be performed strictly according to regulations; otherwise, the quality of the connection will be affected.

[0003] In summary, all of the above-mentioned connecting components have the following disadvantages: Traditional connecting components have low strength, which leads to cracks or deformation at the connection points, reducing the stability of the connection between steel and concrete structures. Utility Model Content

[0004] The purpose of this utility model is to provide a high-strength connection component between steel structure and concrete structure, so as to solve the problem mentioned in the background art that the traditional connection component itself has low strength, which leads to cracks or deformation at the connection part and reduces the stability of the connection between steel structure and concrete structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength connection component between a steel structure and a concrete structure, comprising a support assembly, the support assembly comprising a base plate and a height plate, the middle of the top of the base plate being fixedly connected to the bottom of the height plate, a top plate being fixedly installed on the top of the height plate, a connection assembly being fixedly installed on one side of the top of the top plate, a purlin support plate being fixedly installed on the top plate through the connection assembly, purlin support pieces being threadedly connected to both sides of the purlin support plate, and angle plates being fixedly installed at the four corners of the top of the base plate; the connection assembly comprising a vertical plate and a triangular plate, the middle of one side of the vertical plate being fixedly connected to one side of the triangular plate.

[0006] Preferably, both of the aforementioned support components include an extension plate and an assembly plate. Each of the four corners of one side of the assembly plate is threaded with a fixing bolt. The assembly plate is fixedly connected to the side of the extension plate opposite to it by a fixing bolt located on one side, and the assembly plate is fixedly connected to the side of the support plate opposite to it by a fixing bolt located on the other side. When the user tightens the fixing bolt, the thread on the surface of the fixing bolt matches the thread on the inner wall of the support plate. The fixing bolt rotates and translates relative to the support plate, assembling the support component and the support plate together.

[0007] Preferably, the surface of the upright plate is threaded with four high-strength expansion bolts arranged in a rectangular shape. The upright plate is fixedly connected to the support plate by the high-strength expansion bolts. When the user tightens the high-strength expansion bolts, the threads on the surface of the high-strength expansion bolts match the threads on the inner wall of the support plate. The high-strength expansion bolts rotate and translate relative to the support plate, assembling the upright plate and the support plate together.

[0008] Preferably, the bottom end of the upright plate is fixedly connected to the top plate, and the connecting assembly is installed on the top plate through the upright plate.

[0009] Preferably, each of the four angle pieces is threaded with a first ordinary bolt, and each of the four angle pieces is fixedly mounted with a corner brace by the first ordinary bolt. When the user screws the first ordinary bolt, the thread on the surface of the first ordinary bolt matches the thread on the inner wall of the angle piece, and the first ordinary bolt rotates and translates relative to the angle piece, assembling the angle piece and the corner brace together.

[0010] Preferably, each of the four corner supports is threaded with a second ordinary bolt. Each of the four corner supports is fixedly connected to the opposite side of the two purlin supports by the second ordinary bolt. When the user screws the second ordinary bolt, the thread on the surface of the second ordinary bolt matches the thread on the inner wall of the purlin support. The second ordinary bolt rotates and translates relative to the purlin support, assembling the corner support and the purlin support together.

[0011] Preferably, several reinforcing plates are fixedly installed on both sides of the height plate. The installation of the reinforcing plates increases the connection area between the top plate and the bottom plate, thereby improving the compressive strength of the entire support assembly.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By setting up a purlin support, corner brace, and ordinary bolts, the three components form two sides of a triangle on both sides of the support component. They work together with the support component to form a stable triangle, enabling the entire connection structure to withstand greater loads and reducing the requirements for component cross-sectional dimensions. The bolted connection distributes stress evenly through pre-tightening force, reducing the risk of deformation, meeting people's usage needs, and improving the stability of the connection.
