[0002] Steel structures are made of steel and are one of the main types of building structures. They are primarily composed of components such as steel beams, steel columns, and steel trusses made from sections of steel and steel plates. Crossbeams are placed transversely, perpendicular to the longitudinal beams, and are often arranged along the short axis of the building. To achieve load-bearing properties, these beams are assembled for ease of use. However, in existing technologies, when installing assembled crossbeams on steel structures, the crossbeam mounting plates need to be aligned with the fixing holes on the steel structure to secure the crossbeams. However, during installation, the crossbeams tend to move horizontally, making it difficult to align the crossbeams with the fixing holes on the steel structure, making it difficult to quickly install the crossbeams. Summary of the Invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art that the beam is easy to move in the horizontal direction, making it inconvenient to align the beam with the fixing holes on the steel structure and inconvenient to quickly install the beam, and to propose an assembled large-section steel structure beam.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1

[0026] Reference Figure 1-4 , an assembled large-section steel structure crossbeam, comprising a first beam body 1, two symmetrically arranged second beam bodies 2, two symmetrically arranged first mounting plates 3, two symmetrically arranged guide mechanisms 5 and a support mechanism 6, wherein:

[0027] The two ends of the first beam body 1 are inserted into different second beam bodies 2, and two symmetrically arranged first mounting plates 3 are fixedly connected to different second beam bodies 2. The first mounting plate 3 is used to install and fix the second beam body 2. The second beam body 2 and the first mounting plate 3 are an integral structure. A mounting hole 4 is opened on the first mounting plate 3, and the mounting hole 4 is convenient for fixing the first mounting plate 3 by bolts. Two symmetrically arranged guide mechanisms 5 are connected to different second beam bodies 2. The guide mechanism 5 is used to guide and limit the first mounting plate 3 when it is installed, so that the first mounting plate 3 is quickly aligned with the fixing hole on the steel frame. The support mechanism 6 is fixedly connected between the two symmetrically arranged second beam bodies 2, and the support mechanism 6 is used to support the connection between the first beam body 1 and the second beam body 2;

[0028] The guide mechanism 5 includes a clamping seat 51, a fixing rod 52, a second mounting plate 53 and two symmetrically arranged rollers 54. The clamping seat 51 is fixedly connected to the bottom end of the second beam body 2. The clamping seat 51 is used to connect the fixing rod 51. One end of the fixing rod 51 is clamped to the clamping seat 51. The fixing rod 51 is used to fix the second mounting plate 53. The other end of the fixing rod 52 is fixedly connected to the second mounting plate 53. The second mounting plate 53 is used to mount the rollers 54. The two symmetrically arranged rollers 54 are connected to the second mounting plate 53.

[0029] The support mechanism 6 includes two symmetrically arranged groove frames 61 and a support plate 62. The two symmetrically arranged groove frames 61 are connected to different second beam bodies 2. The groove frames 61 are used to connect the support plates 62. The support plates 62 are used to support the connection between the first beam body 1 and the second beam body 2. The support plate 62 is connected between the two symmetrically arranged groove frames 61.

[0030] Working process: After the two ends of the first beam body 1 are inserted into different second beam bodies 2, the support plate 62 is connected between two symmetrically arranged groove frames 61 to fix the first beam body 1 and the second beam body 2, and the fixing rod 52 is clamped on the base 51. The second mounting plate 53 is located on the outside of the steel frame, and the roller 54 contacts the surface of the steel frame. When the second beam body 2 moves in the vertical direction, the roller 54 rolls on the surface of the steel frame, and the second beam body 2 is guided and limited by the fixing rod 52, so that the second beam body 2 will not move in the horizontal direction. The second beam body 2 drives the first mounting plate 3 to move in the vertical direction, which is convenient for quickly aligning the first mounting plate 3 with the fixing hole on the steel frame, thereby speeding up the installation of the beam.

[0031] Example 2

[0032] When the first mounting plate 3 is fixed by bolts, there is a gap between the bolts and the mounting hole 4. Water will flow into the gap between the bolts and the mounting hole 4 and corrode the mounting hole 4. Figure 1-4 As another preferred embodiment of the present invention, on the basis of embodiment 1, it further includes a sealing mechanism 7, the sealing mechanism 7 includes a fixing ring 71 and a sealing ring 72, the fixing ring 71 is fixedly connected to the first mounting plate 3, the fixing ring 71 is used to install the sealing ring 72, the fixing ring 71 is located on the outside of the mounting hole 4, the sealing ring 72 is connected to the fixing ring 71, the sealing ring 72 is a rubber ring, which is fixed by bolts, and the sealing ring 72 is located between the fixing ring 71 and the bolts, thereby sealing the gap between the fixing ring 71 and the bolts, thereby preventing water from entering the mounting hole 4.

[0033] Example 3

[0034] Since the first beam body 1 and the second beam body 2 are hollow structures, when the first beam body 1 is inserted into the second beam body 2, the connection between the first beam body 1 and the second beam body 2 is relatively fragile. When the beam is subjected to pressure, the connection between the first beam body 1 and the second beam body 2 is easy to bend. Figure 1-5 As another preferred embodiment of the present invention, on the basis of Example 1, it further includes a reinforcement mechanism 8, the reinforcement mechanism 8 including a first fixing frame 81, a second fixing frame 82, a first connecting rod 83 and a fixing nut 84, the first fixing frame 81 and the second fixing frame 82 are fixedly connected to different second beam bodies 2, the first fixing frame 81 is used to fix the first connecting rod 83, one end of the first connecting rod 83 is fixedly connected to the first fixing frame 81, the other end of the first connecting rod 83 passes through the second fixing frame 82, and the other end of the first connecting rod 83 is fixedly connected to the fixing nut 84, the fixing nut 84 is used to fix the first connecting rod 83, a plurality of first connecting rods 83 are provided and are evenly spaced along the length direction of the first fixing frame 81, and the first connecting rods 83 are connected by the first fixing frame 81 and the second fixing frame 82. After the crossbeam is subjected to pressure, the first connecting rod 83 supports the first beam body 1 and the second beam body 2, reduces the pressure on the connection between the first beam body 1 and the second beam body 2, thereby making it less likely for the first beam body 1 and the second beam body 2 to bend.

[0035] Example 4

[0036] Since the first beam body 1 is plugged into the second beam body 2, there is a gap between the first beam body 1 and the second beam body 2. Moisture gas will enter the first beam body 1 through the gap between the first beam body 1 and the second beam body 2, causing corrosion inside the first beam body 1. Figure 1-4 As another preferred embodiment of the present invention, on the basis of Example 1, it further includes an anti-corrosion mechanism 9, the anti-corrosion mechanism 9 includes a fixed block 91, a second connecting rod 92, a mounting block 93, a groove 94 and a hygroscopic filler layer 95, the fixed block 91 is fixedly connected to the first beam body 1, the fixed block 91 is used to fix the second connecting rod 92, one end of the second connecting rod 92 is fixedly connected to the fixed block 91, the second connecting rod 92 is used to connect the mounting block 93, the other end of the second connecting rod 92 is fixedly connected to the mounting block 93, the groove 94 is opened on the mounting block 93, the groove 94 is used to install the hygroscopic filler layer 95, the hygroscopic filler layer 95 is arranged on the groove 94, the hygroscopic filler layer 95 is located at the connection between the first beam body 1 and the second beam body 2, the hygroscopic filler layer 95 is a hygroscopic cotton filler layer, and the hygroscopic filler layer 95 is used to dry the gas entering the first beam body 1.
