Description

Technical Field

[0001] This utility model belongs to the field of steel structure exterior technology, specifically relating to an adjustable connection structure for steel structure exteriors. Background Technology

[0002] Steel structures refer to structural systems assembled from steel components such as steel beams, steel columns, and steel pipe trusses. They are often used to construct houses, outdoor elevators, or canopies. To improve the aesthetics and lighting capabilities of steel structures, existing technologies typically involve installing glass panels on the outside of the steel structure. When installing glass panels, it is necessary to weld the connecting claws to the outer surface of the steel structure. However, when the welding position of the connecting claws deviates, it is not easy to adjust them.

[0003] Chinese patent CN221823172U discloses a glass curtain wall connector. This design includes a connector body with connector arms on its side walls and connector heads at the top of the arms. An adjustment mechanism is located in the middle of the connector body. The adjustment mechanism includes an adjustment groove, a fixing bolt, an adapter, a limiting groove, and limiting teeth. The adjustment groove is vertically shaped, and the fixing bolt is inserted through it. The adapter is threaded onto the fixing bolt. The limiting groove is located on the side of the connector body facing the adapter, and the limiting teeth are located on the side of the adapter facing the connector body, engaging with the limiting groove. This design utilizes the fixing bolt to push the connector body to press the adapter, allowing for fine-tuning of the connector body's installation position.

[0004] When using the above solution, the adapter needs to be fixedly connected to the main structure. However, the installation angle of the adapter is difficult to control. When the length direction of the limiting tooth is tilted to the horizontal plane, the main body of the connecting claw cannot rotate relative to the adapter, so the installation angle of the connecting claw cannot be adjusted, which may have an adverse effect on the installation of the glass plate. Utility Model Content

[0005] The present invention aims to provide an adjustable connection structure for steel structure external mounting to solve the problem that the installation angle of the main body of the connecting claw cannot be adjusted in the above-mentioned solutions.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable connection structure for steel structure exterior is installed on the main body of the steel structure. It includes a connecting claw body and an adjustment component. Connecting arms are spaced apart on the side wall of the connecting claw body. Connecting heads are provided at the ends of the connecting arms. Clamping components are provided on the connecting heads. A first through groove is opened on the front side of the connecting claw body. A first limiting tooth is spaced apart on the rear side wall of the connecting claw body. The adjustment component includes a movable seat and a fixed seat. A first limiting groove is spaced apart on the front side of the movable seat. A first bolt threaded into the movable seat passes through the first through groove. A second limiting tooth is spaced apart on the rear side wall of the movable seat along its circumference. The fixed seat is fixedly installed on the main body of the steel structure. A second limiting groove is spaced apart on the front side of the fixed seat along its circumference. A second bolt threaded into the fixed seat passes through the movable seat along its axial direction.

[0008] The principle and effects of this technical solution:

[0009] During installation, firstly, the fixed seat is welded to the outer wall of the main steel structure. Then, the second bolt is passed through the movable seat and threaded into the fixed seat. The movable seat is rotated until the length of the first limiting groove is parallel to the horizontal plane. Then, the second bolt is rotated further, causing the bolt cap to push the movable seat against the fixed seat and the second limiting tooth to engage in the corresponding second limiting groove. The first bolt is passed through the first through groove and inserted into the movable seat. After moving the connecting claw body up and down to the appropriate position according to the predetermined installation position, the first bolt is rotated further, causing the bolt cap to push the connecting claw body against the movable seat and the first limiting tooth to engage in the corresponding first limiting groove.

[0010] With the above settings, the movable seat can be rotated after the fixed seat is fixed on the steel structure body, which facilitates the rotation of the connecting claw body, reduces the installation accuracy requirements of the fixed seat, and thus reduces the construction difficulty. Furthermore, the movable seat and the connecting claw body can be fixed separately after the movable seat is rotated to the appropriate position and the connecting claw body is moved to the appropriate height, thereby improving the stability and safety of the device during use.

[0011] In this utility model, the front side of the movable seat is provided with a first screw hole along its axial direction, the threaded section of the first bolt is fitted into the first screw hole, the end wall of the first screw hole is provided with a through hole, the front side of the fixed seat is provided with a second screw hole, the second bolt passes through the through hole and is fitted into the second screw hole.

[0012] In this invention, a second through groove is provided on the front side of the connector.

[0013] In this invention, the length direction of the second through groove is perpendicular to the length direction of the first through groove.

[0014] In this utility model, the clamping assembly includes a threaded rod, a connecting shaft is fixedly provided at the front end of the threaded rod, a first clamping plate is fixedly provided at the front end of the connecting shaft, a second clamping plate is threaded onto the external thread of the connecting shaft, the threaded rod passes through a second through groove, and nuts are respectively fitted on the front and rear sides of the outer side wall of the threaded rod to the connector.

[0015] The principle and effects of this technical solution:

[0016] When installing the glass plate, pass the connecting shaft through the pre-drilled hole in the glass plate, then put the second clamping plate on the connecting shaft, and clamp the glass plate with the first and second clamping plates. Then put the nut on the threaded rod and rotate the nut to move it to the appropriate position. Pass each threaded rod on the glass plate through the corresponding second through groove and make the nut abut against the connector. Then put another nut on the threaded rod on the back side of the connector. After moving the glass plate along the length of the second through groove to the appropriate position, continue to rotate the other nut until the two nuts press the connector tightly.

[0017] The above settings allow for adjustment of the distance between the connecting shaft and the connector, thereby allowing for adjustment of the installation distance between the glass panel and the main steel structure.

[0018] In this invention, a washer is fitted onto the front side of the first bolt outside the connector claw body, and a washer is fitted onto the threaded rod between the nut and the connector. This arrangement increases the contact area between the first bolt and the connector claw body, and between the nut and the connector, thereby improving the tightness and effectiveness of the connection.

[0019] In this invention, a sleeve is fixedly provided on the outer periphery of the front side of the fixed base, and the movable base is inserted into the sleeve. This design prevents the second bolt from being subjected to excessive shear force, thereby preventing bending deformation and improving the stability and safety of the device during use.
