Description

Technical Field

[0001] This invention relates to an easy-to-install steel structure connector, which is a connector used during the installation of steel structures. It belongs to the field of steel structure technology, and particularly relates to a connector that can solve the problems of unstable connection and difficulty in changing angle during the installation of steel structures. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of components such as beams, columns, and trusses made of steel sections and plates. These components are typically connected by connectors. Due to their light weight and ease of construction, they are widely used in large factories, stadiums, and high-rise buildings. In steel structures, connectors are a core component, directly affecting the structure's strength, stability, and durability. Traditional steel structure connections often use welding to connect concrete steel columns and beams. However, this method requires extensive welding processes and specialized equipment during on-site construction, resulting in high construction difficulty, long construction time, and difficulties in quality control. Furthermore, under long-term tension and compression of the steel beams, deformation or even breakage can easily occur at the contact points, affecting the overall stability of the steel structure. Existing connectors are mostly fixed structures and cannot be adjusted according to the bending or installation angle of the steel structure, affecting their usability.

[0003] Publication number CN110331786B relates to a steel structure connector, including an embedded frame, a snap-fit ​​base, a linkage inner column, a connecting frame, and a sealing rubber sleeve. The snap-fit ​​base is installed at the lower end of the embedded frame, and the linkage inner column is located in the middle of the snap-fit ​​base. The connecting frame is evenly embedded in the embedded frame, and the sealing rubber sleeve is located in the middle of the upper end of the embedded frame. This invention can solve the problems of structural fixation of commonly used connectors, the need for matching connectors to connect components or parts with different installation angles, the need to sequentially assemble different types of connectors before assembly, the large quantity to carry, and the inconvenience of missing some. Commonly used connectors are mostly integrally formed structures, requiring complete replacement when an assembled connector is damaged, which is cumbersome and time-consuming. Furthermore, this connector only supports the steel structure and cannot provide functionality for steel structures requiring angle changes, thus affecting its use. Summary of the Invention

This connector utilizes a pre-installed steel plate fixing plate and a connecting steel plate fixing plate connected by fixing bolts, and a rotating support body that rotates in a rotating body placement slot to adjust the installation angle.

Example 2

[0013] The difference between this embodiment and embodiment 1 is that: the main structural block (2) has a main structural block side plate threaded hole (14), the main structural block side plate threaded hole (14) is integrally formed with the main structural shell, the main structural block side plate threaded hole (14) is located on one side of the rotating body placement groove (12), the rotating support (1) has a rotating body side plate threaded hole (13) and is connected to the main structural block side plate threaded hole (14), and a fixing bolt (5) is placed between the main structural block side plate threaded hole (14) and the rotating body side plate threaded hole (13); in use, the fixing bolt (5) can be threaded through the main structural block side plate threaded hole (14) and the rotating body side plate threaded hole (13) to make a threaded connection, so that the rotating support (1) after the angle is adjusted is fixed by the rotating angle threaded hole (6) and the fixing bolt (5) for further fixing, thereby increasing the stability of the connecting parts; Example 3

[0014] The difference between this embodiment and embodiment 1 is that: a rubber pad (15) is placed on the connecting steel plate fixing plate (7). The rubber pad (15) has a rectangular structure and is fixedly connected to the connecting steel plate fixing plate (7). The rubber pad (15) has a threaded hole for fixing the connecting steel plate and is made of rubber material. In use, the rubber pad (15) can increase the friction between the connecting steel plate and the connecting steel plate, and at the same time, it can reduce the impact force on the connecting steel plate on the connecting steel plate fixing plate (7), prevent the impact force from being too large, and prevent damage to the connecting steel plate, thus affecting the use effect. The design of having an original steel plate placement groove (3) at one end of the main structural block (2) can limit the position of the original steel plate through the original steel plate placement groove (3), making it more stable to connect with the main structural block (2) and the original steel plate fixing plate (4), thereby increasing the stability of the connector. The design of the rotating body placement groove (12) at the other end of the main structural block (2) can limit the position of the rotating support (1) and prevent it from shifting when the angle is adjusted, which would cause the connection between the connecting steel plate and the original steel plate to be unstable and affect its use. The design of the rotating support (1) being made of stainless steel can increase the hardness and wear resistance of the rotating support (1) and extend its service life. The design of connecting the fixed rotating body threaded hole (11) and the rotating angle threaded hole (6) allows the fixed rotating support (1) to be fixed in the position of the rotating body in the rotating body placement groove (12) by threading the fixed bolt (5) through the fixed rotating body threaded hole (11) and the rotating angle threaded hole (6), making it more stable in use. The design of the original steel plate fixing plate (4) can extend the contact area between the main structural block (2) and the original steel plate through two symmetrically arranged original steel plate fixing plates (4), thereby fixing it by fixing bolts (5) and increasing the stability of the connecting parts. The original steel plate fixing plate (4) is designed to be made of stainless steel, which can increase the hardness and wear resistance of the original steel plate fixing plate (4) and extend its service life. The design of the connecting steel plate placement groove (8) can limit the position of the connecting steel plate through the connecting steel plate placement groove (8), preventing the connecting steel plate from shifting during use, resulting in poor stability and affecting use; The design of the connecting steel plate fixing plate (7) being made of stainless steel can increase the hardness and wear resistance of the connecting steel plate fixing plate (7) and extend its service life. The design of the connecting steel plate fixing plate (7) having a fixed connecting plate threaded hole (9) allows the connecting steel plate to be fixed by passing the fixing bolt (5) through the fixed connecting plate threaded hole (9), ensuring the stability of the connecting steel plate during use, thereby ensuring the stability of the connection between the original steel plate and the connecting steel plate. The purpose is to achieve the connection between the original steel plate fixing plate (4) and the connecting steel plate fixing plate (7) using fixing bolts (5), and to adjust the installation angle of the rotating support body (1) in the rotating body placement groove (12).
