A steel bracket connecting fastener

Abstract

This utility model discloses a steel support frame connecting fastener, comprising: a pin for hinged cross bracing; a locking buckle for locking onto a steel column, the locking buckle having a strip-shaped adjustment hole extending horizontally; an ear seat connected to the locking buckle, one end of the ear seat having a hinge hole and the other end having a bolt hole; a bolt for fastening the connection; and a washer plate disposed between the ear seat and the locking buckle. This utility model provides a steel support frame connecting fastener that is manufactured in a factory and installed on-site. When erecting a steel support frame, the cross bracing is installed on-site, usually by welding: on-site welding easily causes air pollution and consumes manpower and resources, resulting in certain economic losses. This new steel support frame connecting fastener solves these problems by using a welding-free method.

Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a steel bracket connecting fastener. Background Technology

[0002] The erection of temporary steel scaffolding is widely required in fields such as bridge engineering and building construction. In traditional construction, steel columns and cross braces are typically connected by on-site welding, which has the following drawbacks:

[0003] Environmental pollution: Welding exhaust and welding slag pollute the construction environment;

[0004] Waste of resources: Dismantling requires damaging the welding points, resulting in damage to the base material, making it difficult to reuse;

[0005] Inefficient: Welding operations rely on manual labor, which is time-consuming and labor-intensive, increasing construction costs.

[0006] Therefore, there is an urgent need for a weld-free, reusable fastener to improve construction efficiency and reduce resource consumption. Utility Model Content

[0012] The ear seat connected to the latch has a hinge hole at one end and a bolt hole at the other end;

[0013] Bolts used for fastening connections;

[0014] A pad is provided between the ear seat and the buckle.

[0015] As a further technical solution of this utility model: the buckle is U-shaped or L-shaped, and is fastened to the connecting ear plate on the outside of the steel column by the bolt passing through the mounting hole of the buckle, or directly hugs the outer wall of the steel column.

[0016] As a further technical solution of this utility model: the bolt hole of the ear seat is provided in correspondence with the strip-shaped adjustment hole of the buckle, and the bolt passes through the bolt hole of the ear seat and the strip-shaped adjustment hole of the buckle, so that the ear seat can move laterally along the strip-shaped adjustment hole.

[0017] As a further technical solution of this utility model: the pad is a rectangular or circular metal plate with countersunk holes on the surface for engagement with bolts.

[0018] As a further technical solution of this utility model: the end of the cross brace is provided with a connecting hole that cooperates with the pin, and the pin passes through the connecting hole of the cross brace and the hinge hole of the ear seat.

[0019] As a further technical solution of this utility model: the length of the strip-shaped adjustment hole of the buckle is 5000±10mm, allowing the lateral adjustment range of the ear seat to be not less than 50mm.

[0020] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0021] Weld-free construction: The entire process uses bolts and pins for connection, avoiding on-site welding pollution and improving construction safety;

[0022] Reusable: The components are undamaged after disassembly and can be reused multiple times, reducing costs;

[0023] Easy installation: Installation errors can be compensated by adjusting the position of the ear mounts, improving assembly efficiency;

[0024] Load distribution: The pad increases the contact area, improving the stability and fatigue resistance of the connection. Attached Figure Description

[0032] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] Example 1, such as Figure 1-6 As shown, a steel bracket connecting fastener includes components such as a pin, a locking buckle, an ear seat, a bolt, and a pad.

[0034] The two locking buckles are connected by four bolts and seven steel columns.

[0035] The three ear seats are connected by four bolts, six washers, and two locking buckles.

[0036] The 5 cross braces are connected to the 3 ear seats via a pin, and the 3 ear seats can move laterally through the strip hole on the 2 locks, thereby reducing the installation error of the 3 ear seats and the 5 cross braces.

[0037] The working principle is as follows:

[0038] Steel support frame connecting fasteners are manufactured in the factory and installed on-site. During steel support frame construction, cross braces are typically installed on-site using welding. However, on-site welding easily pollutes the air and is costly in terms of manpower and resources, resulting in economic losses. This paper proposes a steel support frame connecting fastener that solves these problems by using a welding-free method. In this fastener, the locking buckle 2 is locked to the steel column 7 via bolts 4, the lug 3 is connected to the locking buckle 2 via bolts 4 and a washer 6, and the cross brace 5 is connected to the lug 3 via a pin 1. This eliminates welding points during steel support frame assembly, allows for reuse after installation and disassembly without damage, reduces resource waste, and improves the project's economic efficiency.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment have been appropriately combined to form other embodiments that are easy for those skilled in the art to understand.
