Description

Technical Field

[0001] The utility model relates to an auxiliary component, in particular to a lossless auxiliary component for a main connecting piece of a steel structure, belonging to the technical field of steel structures. Background Art

[0002] Steel structure connection refers to the mutual connection between steel structure members or components. Steel structure connection is usually welded, bolted or rivet. Bolt connection is divided into ordinary bolt connection and high-strength bolt connection. Ordinary bolt connection was used the earliest, starting from the middle of the 18th century. Rivet connection began to be used in the 1920s. Weld connection appeared in the second half of the 19th century. When some steel structures are connected, they generally include steel pipes and I-beams. The application of such steel structures is also extremely extensive. When steel pipes and I-beams are connected, connecting components are needed;

[0003] However, the existing steel structure connection components cannot be used for fixed auxiliary connection of I-beam structures of different sizes, and therefore have certain limitations in use, poor size applicability, and reduced use effect and practicality. Utility Model Content

[0004] The utility model provides a non-destructive auxiliary component of a main connecting piece of a steel structure, which is used to solve the problems raised in the background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] The utility model discloses a non-destructive auxiliary member for a main connecting member of a steel structure, comprising an upper connecting member and a lower connecting member, wherein the upper connecting member is arranged above the lower connecting member, and the upper connecting member and the lower connecting member are fixedly connected by welding, a primary steel plate is fixedly installed on the front outer wall of the upper connecting member, a secondary steel plate is fixedly installed on the front outer wall of the lower connecting member, sub-steel plates are fixedly installed on the front outer walls of the primary and secondary steel plates by welding, an upper auxiliary splint is fixedly installed on the upper outer wall of the sub-steel plate by welding, and a lower auxiliary splint is fixedly installed on the lower outer wall of the sub-steel plate by welding.

[0007] Furthermore, in order to facilitate auxiliary clamping and fixing, two groups of symmetrically distributed clamping through holes are provided on the upper auxiliary clamping plate and the lower auxiliary clamping plate, and the clamping through holes are threaded through holes.

[0008] Furthermore, in order to ensure a normal clamping and fixing effect, a clamping screw pin matching the hole diameter and thread is arranged outside the clamping through hole.

[0009] Furthermore, in order to improve the compressive structural strength of the upper auxiliary splint and the lower auxiliary splint, the upper surface of the upper auxiliary splint and the lower surface of the lower auxiliary splint are both fixedly installed with triangular reinforcement ribs by welding, and one end of the triangular reinforcement ribs is welded and fixed to the corresponding sub-steel plate.

[0010] Furthermore, in order to facilitate the description of the size and shape of the upper connecting member and the lower connecting member, the upper connecting member and the lower connecting member both adopt a "concave" structural design, and side reinforcing plates are fixedly installed on the outer walls on both sides of the upper connecting member.

[0011] Furthermore, in order to improve the overall structural strength of the splint, the number of triangular reinforcing ribs on the upper surface of the upper auxiliary splint is not less than three.

[0012] Compared with the prior art, the utility model provides the following beneficial effects:

[0013] The utility model provides an upper auxiliary clamping plate and a lower auxiliary clamping plate on the upper connecting member and the lower connecting member. When the utility model needs to perform auxiliary connection on the I-shaped steel of the main connecting member of the steel structure, the I-shaped steel of the main connecting member can be placed between the upper auxiliary clamping plate and the lower auxiliary clamping plate. By providing clamping through holes and clamping screws on the upper auxiliary clamping plate and the lower auxiliary clamping plate, the clamping screws can be rotatably screwed into the clamping through holes. In this way, the I-shaped steel in the upper auxiliary clamping plate and the lower auxiliary clamping plate can be effectively clamped and fixed by the clamping screws provided above and below, thereby playing a role of lossless auxiliary connection.

[0014] Among them, the structural design of the clamping screw makes the utility model applicable to different sizes of I-shaped steel for auxiliary fixation, has a wider range of size application, reduces usage limitations, and thus improves the overall use effect and practicality of the utility model.

[0029] Working principle: The utility model is provided with an upper auxiliary clamping plate 7 and a lower auxiliary clamping plate 8 on the upper connecting member 1 and the lower connecting member 3.
