Description

Technical Field

[0001] The utility model relates to the technical field of steel structure connection, in particular to a telescopic steel structure connector. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates. Welds, bolts or rivets are usually used to connect between the components or parts. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields.

[0003] A steel structure connector refers to the connection part between the components in a steel structure. Through the high-strength materials of the steel structure, sufficient strength and stiffness are generated at the connection part, so that the entire structure can generate and transmit corresponding forces and bending moments, thus having strong seismic resistance and stability. The significance of steel structure connection is that it can ensure that the steel structure is not easily deformed or damaged when subjected to external forces or earthquakes, and ensure the safety and stability of the building. In addition, rigid connection can also ensure the integrity of the steel structure and enhance the bearing capacity and flexural resistance of the steel structure.

[0004] The inventor found the following problems in the process of realizing the utility model: 1. Due to the influence of temperature, the deformation of the steel structure combined with the existing connectors caused by the change of air temperature cannot be withstood by it; 2. The connector cannot meet the stability of the structure. When the steel structure deforms, it cannot meet the requirements of its deformation. It can only mechanically connect the steel structures together and cannot adapt to the deformation generated by it. Moreover, when the external force disappears, the connection part cannot return to the original state. Content of the Utility Model

[0005] The purpose of the utility model is to provide a telescopic steel structure connector to solve the problems put forward in the above background technique. To achieve the above purpose, the utility model provides the following technical scheme: A telescopic steel structure connector, including a chute steel pipe, a pulley is slidably connected inside the chute steel pipe, a limit channel steel is slidably connected inside the chute steel pipe, a fixed steel plate is welded on one side of the limit channel steel, a steel connection plate member is welded on one side of the fixed steel plate, a movable rod is hinged on one side of the fixed steel plate, a positioning rod is inserted inside the movable rod, a telescopic spring is inserted on one side of the positioning rod, and a connection steel plate is welded at one end of the positioning rod.

[0006] Further preferably, an empty groove is opened inside the chute steel pipe, and the pulley is in contact with both ends of the empty groove.

[0007] Further preferably, empty grooves are formed on both sides of the limit channel steel, and the inner part of the empty groove of the limit channel steel is attached to the surface of the pulley, and the bolt holes distributed coaxially are all the same size as the bolt holes inside the chute steel pipe.

[0008] Further preferably, the steel connection plates are symmetrically distributed about the center line of the fixed steel plate.

[0009] Further preferably, the movable rod includes four steel brackets with the same size and structure, one end of the steel bracket is fixed on the fixed steel plate, and the other end of the steel bracket is in the shape of a round hole and is sleeved on the positioning rod.

[0010] Further preferably, both the telescopic spring and the movable rod are sleeved on the positioning rod.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, the addition of the slide rail enables the steel structure connecting piece to be adjusted correspondingly according to the changes required by the structure of the steel structure itself to meet the required use conditions, and it is convenient to bear and adjust the force generated transversely, so that it reaches the acceptable standard, and has the ability to maintain its original balanced state, that is, it has sufficient stability to ensure that it will not be unstable and damaged under different use conditions, always maintaining the integrity of the steel structure, so that it will not affect the steel structure and has a longer service life.

[0013] In the present utility model, the movable rod and the telescopic spring in the front part of the connecting piece enable the connection part of the steel structure to have the functions of extension and resilience. When the steel structure is subjected to external pressure, it can adjust the length of the connecting piece to adapt to different deformations caused by structure or temperature changes, and after these external factors disappear, it can return to the initial state. It can effectively improve the service life of the steel structure, improve the load-bearing capacity of the steel structure, thereby realizing the telescopic control of the steel structure, and effectively avoiding the damage and destruction of the steel structure.
