Technical Field
[0001] This utility model belongs to the field of steel structure connection technology, and in particular relates to a connection structure for a steel structure cantilever sealing beam. Background Technology
[0002] Steel pipe beams are one of the core load-bearing components of steel structure residential buildings. They are usually made of round steel pipes, square steel pipes or H-beams and are connected to steel columns, steel trusses, etc. by welds to form the main load-bearing system of the building. Their design aims to utilize the high strength and lightweight properties of steel to meet the structural requirements of large span and high load-bearing capacity.
[0003] In existing technologies, when steel pipe beams of steel structure residential buildings cantilever in two directions to form an L-shape, they are often connected by direct welding. However, there is usually no positioning structure between the two beams, which makes the welding operation between the two beams inconvenient and difficult, thus reducing the efficiency of the connection work. Utility Model Content
[0004] This utility model provides a connection structure for a steel structure cantilevered sealing beam, aiming to solve the problem that in the prior art, when steel pipe beams of steel structure residential buildings cantilever in two directions to form an L shape, the connection is mostly made by direct welding, which makes the welding operation between the two beams inconvenient.
[0005] This utility model is implemented as follows: a connection structure for a steel structure cantilevered sealing beam includes a first cantilever beam and a second cantilever beam, both of which are open at both ends. One end of the first cantilever beam and one end of the second cantilever beam form a vertical angle. A flat plate and a U-shaped plate are respectively fixedly connected to the front and rear sides of one end of the inner wall of the second cantilever beam. The top and bottom ends of the first cantilever beam are respectively provided with a flat groove adapted to the flat plate and a U-shaped groove adapted to the U-shaped plate.
[0006] Preferably, a second positioning block is fixedly connected to the front side of one end of the inner wall of the first cantilever beam. When the bottom end of the flat plate contacts the top of the second positioning block, after the first cantilever beam and the second cantilever beam are spliced together, the top end of the flat plate is flush with the side wall of the first cantilever beam.
[0007] Preferably, a first positioning block is fixedly connected to the rear side of one end of the inner wall of the first cantilever beam. When the bottom end of the U-shaped plate contacts the top of the first positioning block, after the first cantilever beam and the second cantilever beam are spliced together, the top end of the U-shaped plate is flush with the side wall of the first cantilever beam.
[0008] Preferably, both the first cantilever beam and the second cantilever beam are coated with a primer layer, and the surface of the primer layer is coated with an anti-corrosion coating.
[0009] Preferably, the width of the flat plate and the U-shaped plate is smaller than the inner diameter of the first cantilever beam and the second cantilever beam.
[0010] Beneficial effects
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The connection structure of the steel structure cantilever sealing beam of this utility model involves embedding a flat plate and a U-shaped plate into the interior of the second cantilever beam and then welding them for fixation. Then, the U-shaped groove and flat groove on the first cantilever beam are respectively fitted onto the corresponding flat plate and U-shaped plate, allowing for insertion and positioning between the first and second cantilever beams. The width of the U-shaped plate and the flat plate is slightly smaller than the inner diameter of the first and second cantilever beams, facilitating assembly. Both ends of the first and second cantilever beams are open, facilitating installation and subsequent welding. The use of inserted flat plates and U-shaped plates, positioning, and then welding reduces welding requirements and facilitates welding operations between the first and second cantilever beams. The welding operation is less difficult, thereby improving the efficiency of the connection work. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0018] Please see Figure 1-3 This utility model provides a technical solution: a connection structure for a steel structure cantilevered sealing beam, including a first cantilever beam 1 and a second cantilever beam 2, both of which are open at both ends, with one end of the first cantilever beam 1 and one end of the second cantilever beam 2 forming a vertical angle.
[0019] A flat plate 5 and a U-shaped plate 3 are fixedly connected to the front and rear sides of one end of the inner wall of the second cantilever beam 2, respectively. The top and bottom ends of the first cantilever beam 1 are respectively provided with a flat groove 6 that matches the flat plate 5 and a U-shaped groove 4 that matches the U-shaped plate 3. The width of the flat plate 5 and the U-shaped plate 3 is smaller than the inner diameter width of the first cantilever beam 1 and the second cantilever beam 2.
[0020] After the flat plate 5 and U-shaped plate 3 are embedded into the interior of the second cantilever beam 2, they are welded and fixed. Then, the U-shaped slot 4 and flat slot 6 on the first cantilever beam 1 are respectively fitted onto the outside of the corresponding flat plate 5 and U-shaped plate 3, so that the insertion and positioning work between the first cantilever beam 1 and the second cantilever beam 2 can be carried out.
[0021] The width of the U-shaped plate 3 and the flat plate 5 is slightly smaller than the inner diameter of the first cantilever beam 1 and the second cantilever beam 2, which facilitates the assembly work. Both ends of the first cantilever beam 1 and the second cantilever beam 2 are open, which facilitates installation and welding.
[0022] By inserting a flat plate 5 and a U-shaped plate 3 for positioning and then welding, the welding requirements are reduced, which facilitates the welding operation between the first cantilever beam 1 and the second cantilever beam 2. The welding operation is less difficult, thereby improving the efficiency of the connection work.
[0023] Furthermore, a second positioning block 8 is fixedly connected to the front side of one end of the inner wall of the first cantilever beam 1. When the bottom end of the plate 5 contacts the top of the second positioning block 8, after the first cantilever beam 1 and the second cantilever beam 2 are spliced together, the top end of the plate 5 is flush with the side wall of the first cantilever beam 1.
[0024] In this embodiment, when the plate 5 is embedded inside the second cantilever beam 2, the second positioning block 8 facilitates the positioning of the insertion depth of the plate 5, which facilitates the subsequent welding work between the plate 5 and the first cantilever beam 1. After the connection between the first cantilever beam 1 and the second cantilever beam 2 is welded, the splicing surface between the plate 5 and the first cantilever beam 1 can be welded to increase the welding area, thereby improving the connection strength between the first cantilever beam 1 and the second cantilever beam 2.
[0025] Furthermore, a first positioning block 7 is fixedly connected to the rear side of one end of the inner wall of the first cantilever beam 1. When the bottom end of the U-shaped plate 3 contacts the top of the first positioning block 7, after the first cantilever beam 1 and the second cantilever beam 2 are spliced together, the top end of the U-shaped plate 3 is flush with the side wall of the first cantilever beam 1.
[0026] In this embodiment, when the U-shaped plate 3 is embedded inside the first positioning block 7, the first positioning block 7 facilitates the positioning of the insertion depth of the U-shaped plate 3, which facilitates the subsequent welding work between the U-shaped plate 3 and the first cantilever beam 1. After the connection between the first cantilever beam 1 and the second cantilever beam 2 is welded, the splicing surface between the U-shaped plate 3 and the first cantilever beam 1 can be welded to increase the welding area, thereby improving the connection strength between the first cantilever beam 1 and the second cantilever beam 2.
[0027] Furthermore, both the first cantilever beam 1 and the second cantilever beam 2 are coated with a primer layer 9, and the surface of the primer layer 9 is coated with an anti-corrosion coating 10.
[0028] In this embodiment, the primer layer 9 and the anti-corrosion coating 10 improve the corrosion resistance between the first cantilever beam 1 and the second cantilever beam 2, thereby extending the service life of the first cantilever beam 1 and the second cantilever beam 2, which is beneficial for building splicing and assembly work.
[0029] The working principle and usage process of this utility model are as follows: After the utility model is installed, the flat plate 5 and the U-shaped plate 3 are embedded into the interior of the second cantilever beam 2 and then welded and fixed. Then, the U-shaped slot 4 and the flat slot 6 on the first cantilever beam 1 are respectively fitted onto the outside of the corresponding flat plate 5 and U-shaped plate 3, so that the first cantilever beam 1 and the second cantilever beam 2 can be inserted and positioned. The width of the U-shaped plate 3 and the flat plate 5 is slightly smaller than the inner diameter of the first cantilever beam 1 and the second cantilever beam 2 to facilitate assembly. Both ends of the first cantilever beam 1 and the second cantilever beam 2 are open to facilitate installation and welding. By inserting the flat plate 5 and the U-shaped plate 3, positioning and then welding are performed, the welding requirements are reduced.
[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
