Description

Technical Field

[0001] The utility model relates to the technical field of connecting pieces, in particular to a steel structure connecting piece. Background Art

[0002] There are various types of steel structure connecting pieces. The common one is of a single-plate double-row perforated structure. This kind of steel structure connecting piece requires positioning and drilling, which is rather troublesome. Moreover, when installing and fixing bolts, the bolts or nuts need to be fixed to enable good bolt connection. Content of the Utility Model

[0003] The purpose of the utility model is to provide a steel structure connecting piece to solve the problems put forward in the above background art that the steel structure connecting piece requires positioning and drilling, and when installing and fixing bolts, the bolts or nuts need to be fixed to enable good bolt connection.

[0004] To achieve the above purpose, the utility model provides the following technical solution:

[0005] A steel structure connecting piece includes a connecting plate. Through grooves are symmetrically formed in the connecting plate, and clamping grooves are formed outside the through grooves on the connecting plate.

[0006] As a further description of the above technical solution:

[0007] Chamfers are arranged at the corner positions of the connecting plate.

[0008] As a further description of the above technical solution:

[0009] The chamfers are arc-shaped chamfers.

[0010] As a further description of the above technical solution:

[0011] Both ends of the through groove are arc-shaped.

[0012] As a further description of the above technical solution:

[0013] The end of the clamping groove is arc-shaped.

[0014] As a further description of the above technical solution:

[0015] The depth of the clamping groove is less than 5 mm.

[0016] Compared with the prior art, the utility model provides a steel structure connecting piece, which has the following beneficial effects:

[0017] 1. In the utility model, the original holes are changed into through grooves, so that the processing efficiency is higher, the materials are more saved, and at the same time, the normal hole installation is not affected;

[0018] 2. In the present utility model, a clamping groove is provided on the outer side of the through groove, which can limit the bolts to prevent them from loosening and facilitate bolt connection and fixation. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] LEGEND DESCRIPTION:

[0022] 1. Connection plate; 2. Through groove; 3. Clamping groove. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment:

[0025] Please refer to Figure 1 - Figure 2 , the present utility model provides a steel structure connector, including a connection plate 1, through grooves 2 are symmetrically provided on the connection plate 1, and a clamping groove 3 is provided on the connection plate 1 outside the through groove 2.

[0026] Specifically, as Figure 1 shown, chamfers are provided at the corner positions of the connection plate 1, and the chamfers are arc-shaped chamfers, which are beautiful in appearance and do not hurt people.

[0027] Specifically, both ends of the through groove 2 are arc-shaped.

[0028] Specifically, the end of the clamping groove 3 is arc-shaped.

[0029] Specifically, the depth of the clamping groove 3 is less than 5 mm.

[0030] Working principle:

[0031] Install bolts at the position of the through groove 2 of the connection plate 1. The width of the through groove 2 is the same as the diameter length of the original perforation, and the width of the clamping groove 3 is the same as the size length of the bolt head. Put the bolt down through the through groove 2 to align with the hole, and the bolt head is stuck in the clamping groove 3. In this way, only by rotating the nut can the bolt connection and fixation be completed, and because the bolt head is restricted, the bolt will not rotate and loosen after installation.

[0032] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
