Description

Technical Field

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

[0002] A steel structure hoop is a metal device used for connecting, strengthening or supporting steel structure components. It is usually designed in a circular or semi-circular shape and can tightly "hold" columns, pipelines or other structural components with circular or square cross-sections. The hoop can be fixed to the target structure by bolts, welding or other fastening methods during installation.

[0003] For example, the existing Chinese patent (CN221143080U) discloses a hoop connection component for steel structures, which consists of two steel hoops and twenty stiffening plates, and the two are welded together; there are holes on both sides of the steel hoop, and high-strength large hexagon head bolts are installed therein, and the two steel hoops are connected by the high-strength large hexagon head bolts; a high-temperature resistant structural adhesive is coated on the inner layer of the steel hoop. The hoop connection component for steel structures of the utility model has a simple composition, reasonable design, convenient use, relatively high strength and a certain margin, improving the reliability of the overall connection of the structure; and it is convenient for processing and manufacturing.

[0004] However, during the use of the hoop in the above technical solution, the bolts on both sides need to be tightened to lock the hoop to the steel structure. During the installation process of the hoop, a large number of bolts need to be installed, increasing the complexity of the installation and not facilitating the quick locking of the hoop. Content of the Utility Model

[0005] The purpose of the utility model is to provide a new type of steel structure hoop to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A new type of steel structure hoop, including: semi-circular steel plates and flanges. There are two semi-circular steel plates, and flanges are provided at one end of both semi-circular steel plates. A shaft sleeve is fixed on the outer wall of one of the semi-circular steel plates, and a rotating shaft is fixed on the outer wall of the other semi-circular steel plate. The two semi-circular steel plates are rotationally connected through the shaft sleeve and the rotating shaft. A U-shaped groove is opened in the middle of one end of the flange, and a locking bolt is connected between the flanges. One end of the locking bolt is rotationally connected to one of the flanges, and the nut of the locking bolt abuts against the other flange. A strip-shaped groove is opened inside the semi-circular steel plate, and a connecting bolt is slidably arranged inside the strip-shaped groove. One end of the connecting bolt is provided with a movable clamping plate, and the other end is provided with a connecting seat.

[0007] Further, elastic cushion blocks are arranged between the strip-shaped grooves on the inner wall of the semi-circular steel plate, and one side of the elastic cushion block protrudes from the movable clamping plate.

[0008] Further, the connecting seat is in the shape of a hollow shell, and the outer wall of one side of the connecting seat fits the outer wall contour of the semi-circular steel plate.

[0009] Further, a limit pin is provided on one of the flanges. The limit pin is located on the flange near the nut end of the locking bolt, and the limit pin is located at the open end of the U-shaped groove.

[0010] Further, a fixed shaft is provided inside one of the U-shaped grooves, and one end of the locking bolt is connected to the flange through the fixed shaft.

[0011] Further, there are four connecting seats, and the four connecting seats are evenly arranged circumferentially on the outside of the hoop.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] By providing the semi-circular steel plate, the movable clamping plate and the connecting bolt, the present utility model realizes that when the new steel structure hoop is used, through the shaft connection between the two semi-circular steel plates of the hoop, the hoop can be quickly opened and closed, clamped on the outside of the steel structure, and through the rotational connection between the locking bolt and the flange, the two flanges of the hoop can be quickly locked by the locking bolt, fixing the hoop on the steel structure to realize the quick disassembly and assembly of the hoop. Finally, the limit pin limits one end of the locking bolt to ensure the stability of the hoop.

[0014] During the process of clamping the hoop on the steel structure, the connecting seat provided on the hoop is used for connecting the hoop with other structures. When it is necessary to adjust the position of the connecting seat during the use of the connecting seat due to different installation positions of the hoop, the nut on the connecting bolt can be loosened so that the connecting seat can slide in the strip-shaped groove, thereby adjusting the position of the connecting seat to ensure that the hoop can be smoothly connected and fixed with other steel structure components.
