Description

TECHNICAL FIELD

[0001] The utility model relates to building steel structure technical field, concretely is a steel structure connecting piece for building. BACKGROUND

[0002] Building steel structure is a building structure form with steel as the main load-bearing material. It is mainly composed of square tubes, steel columns, steel trusses and other components made of shaped steel and steel plates, and is connected together through welds, bolts or rivets to form a stable overall structure.

[0003] In the existing building structure, the connection between square tube steel beams and I-beam steel beams is common in the steel structure connection structure. Currently, I-beams are mostly connected to square tubes through L-shaped plates, supplemented by multiple external bolts and rivets for fixation. The installation requires many parts and takes a relatively long time, affecting the assembly efficiency of the steel structure.

[0004] Therefore, we propose to design a steel structure connecting piece for building. SUMMARY

[0008] A trihedron is arranged at the corner between the square tube and the outer wall of the I-beam, and a locking bolt is arranged at the bottom of the trihedron and the side close to the square tube.

[0009] As a preferred scheme of the steel structure connecting piece for building, the length of the inner positioning plate is half of the length of the outer positioning plate, the length of the inner positioning plate is shorter, and the length of the outer positioning plate is longer, which exceeds the depth of the inner positioning plate, to ensure the structural stability of the bolt fixation between the end of the outer positioning plate and the I-beam.

Compared with the traditional multi-bolt fixing structure, this device adopts a combination of plug-in and bolt fixing method. The internal fixing is achieved by plugging in the inner positioning plate, and the external fixing is achieved by bolting the outer positioning plate, which saves half of the bolt installation time and improves the work efficiency of steel structure connection.

[0012] As a preferred embodiment of the steel structure connector for building described in this utility model, a triangular side is provided on one side of the three-sided body, and two three-sided bodies are provided. Limiting posts and limiting grooves are respectively provided on the sides of the two three-sided bodies that are close to each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model effectively shortens the connection time between square tubes and I-beams by using a combination of positioning frame and three-sided body, and by using plug-in connection and a small number of bolts for fixing. At the same time, it improves the connection strength and stability between the two.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Please see Figs. 1-3 This utility model provides a steel structure connector for building, including a square tube 1, an I-beam 2 on the outside of the square tube 1, a positioning frame 3 fixedly connected to the side of the square tube 1 near the I-beam 2, a positioning groove 4 corresponding to the positioning frame 3 is opened at the end of the I-beam 2, the positioning frame 3 includes two outer positioning plates 301, and an inner positioning plate 302 is provided at the center between the two outer positioning plates 301.

[0024] The positioning groove 4 corresponds to and fits with the inner positioning plate 302, which plays a positioning role when the square tube 1 and the I-beam 2 are connected, making it easy for the two to be quickly installed in place when they are docked.

[0025] The two outer positioning plates 301 are respectively attached to the two sides of the outer wall of the I-beam 2. The two outer positioning plates 301 are fixed to the two sides of the I-beam 2 by bolts. Compared with the traditional multi-bolt fixing structure, this device adopts a combination of plug-in and bolt fixing method. The internal fixing is achieved by plugging in the inner positioning plate 302, and the external fixing is achieved by bolting the outer positioning plate 301. This saves half of the bolt installation time and improves the operation efficiency of steel structure connection.

[0026] In this embodiment, the inner positioning plate 302 is half the length of the outer positioning plate 301. The inner positioning plate 302 is shorter, while the outer positioning plate 301 is longer, exceeding the depth of the inner positioning plate 302, in order to ensure the structural stability of the bolt fixation between the end of the outer positioning plate 301 and the I-beam 2.

[0027] A three-sided structure 5 is provided at the corner between the outer walls of the square tube 1 and the I-beam 2. Locking bolts 6 are provided at the bottom of the three-sided structure 5 and on the side closest to the square tube 1.

[0028] A triangular edge is provided on one side of the trihedron 5. There are two trihedrons 5. Limiting posts 7 and limiting grooves 8 are respectively provided on the side of the two trihedrons 5 that are close to each other. The limiting posts 7 and limiting grooves 8 are matched and fit together. Two trihedrons 5 are provided at the corner between the square tube 1 and the I-beam 2. The setting of the limiting posts 7 and limiting grooves 8 facilitates the combination of the two trihedrons 5 and enhances the connection stability between the square tube 1 and the I-beam 2.

[0029] When prefabricating square tube 1 and I-beam 2, a positioning frame 3 is pre-set on the outside of square tube 1, and the outer positioning plate 301 and inner positioning plate 302 are welded and fixed to the outside of square tube 1 as a whole. A positioning groove 4 is opened at the end of I-beam 2.

[0030] During installation, the positioning groove 4 of the I-beam 2 is directly inserted into the inner positioning plate 302. At this time, the outer positioning plate 301 is attached to both sides of the outer wall of the I-beam 2. The outer positioning plate 301 and the I-beam 2 are connected and fixed by bolts. By combining insertion and a small number of bolts, the connection time of the square tube 1 and the I-beam 2 is effectively shortened, while the connection strength and stability between the two are improved.

[0031] When the external load on the I-beam 2 is large, a trihedron 5 can be installed on the outside of the square tube 1 and the I-beam 2. The two sides of the trihedron 5 are fixed to the square tube 1 and the I-beam 2 respectively by the locking bolts 6.

[0032] If the width of the I-beam 2 is large, the two trihedrons 5 can be assembled and fixed. There are corresponding limiting posts 7 and limiting grooves 8 between two adjacent trihedrons 5. The limiting posts 7 and limiting grooves 8 can be inserted and fitted to each other to facilitate quick assembly and fix them to the square tube 1 and the I-beam 2.

[0033] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
