[0002] The H-shaped steel is an economic section high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structural weight, and has been widely used in steel structure buildings.

[0003] However, in the prior art, according to the requirements of on-site construction, when using steel beams, butt joint devices are often required. Currently, during butt joint, the position of the steel beam is usually manually adjusted for butt joint installation. However, due to the large weight of the H-shaped steel beam, on the one hand, manual adjustment is very laborious, and there is a situation where repeated adjustment is required to ensure the accuracy of the butt joint position. Therefore, the operation is relatively inconvenient. At the same time, the structures and functions of some butt joint devices are relatively single, so it needs to be solved.

However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0034] Embodiment 1, as Figures 1-4 shown, the present utility model provides a docking limit mechanism for a steel beam, including: a docking frame 1 and two mounting frames 2; two groups of sliding grooves 101, opened on the surfaces of the symmetric positions of the docking frame 1; further including: two groups of I-shaped blocks 204, both fixedly installed on the symmetric positions of the surfaces of the two mounting frames 2, and a plurality of I-shaped blocks 204 are slidably embedded on the surfaces of the sliding grooves 101; two limit grooves 201, opened on the surfaces of the two mounting frames 2, a bidirectional lead screw 202 is movably embedded inside the two mounting frames 2, and two mounting openings 106 are opened on the surfaces of the symmetric positions of the docking frame 1.

[0035] In this embodiment, when in use, through the mounting openings 106 opened on the surface of the docking frame 1, the mounting openings 106 are sleeved on the outer surface of the I-shaped steel beam, and are quickly guided in cooperation with the guiding grooves 2032. At the same time, the bidirectional lead screw 202 inside the inner wall of the mounting frame 2 is rotated to drive the load-bearing plate 203 to move and contact the inner walls on both sides of the steel beam to position it. At the same time, the limit block 2031 is movably embedded inside the limit groove 201 to prevent tilting during movement. At the same time, the mounting frame 2 fixes the I-shaped block 204. The fastening bolt 2042 is threadedly embedded inside the inner wall of the I-shaped block 204, and one end is embedded inside the reserved hole of the steel beam to further strengthen the fixation, without the need to adjust the position of the steel beam, reducing the workload and having a simple operation.

[0036] Embodiment 2, a bearing plate 203 is sleeved on the surface threads at the symmetric positions of two bidirectional lead screws 202. Multiple bearing plates 203 are evenly divided into groups of two on average. On one side surface of two groups of bearing plates 203, a limit block 2031 is fixedly installed. On the surface at the center of two groups of bearing plates 203, a guiding groove 2032 is formed. One end of multiple limit blocks 2031 is slidably embedded in the inside of the limit groove 201. Through holes 2041 are formed on the surface at the center of multiple I-shaped blocks 204. Tightening bolts 2042 are threadedly embedded on the surface of multiple I-shaped blocks 204. Positioning holes 102 are formed on the surface at the symmetric positions of the docking frame 1. Multiple groups of springs 103 are fixedly installed on the outer surface at the symmetric positions of the docking frame 1. One end surface of multiple groups of springs 103 far from the docking frame 1 is fixedly installed with a connecting frame 104. At the symmetric positions of the surface of multiple connecting frames 104 close to the docking frame 1, positioning pins 105 are fixedly installed. One end of multiple positioning pins 105 is movably embedded in the inside of the positioning hole 102. Multiple positioning pins 105 are evenly divided into groups of two on average.

[0037] In this embodiment, both ends of the spring 103 are respectively connected to the surfaces of the docking frame 1 and the connecting frame 104, providing a resetting ability for the connecting frame 104. When the connecting frame 104 is pulled, the positioning pin 105 on the surface moves inside the positioning hole 102 for limiting work. At the same time, when the positioning pin 105 disengages from the inside of the through hole 2041, the I-shaped block 204 slides inside the limit groove 201, changing the depth of the steel beam embedded in the docking frame 1.

At the same time, the bidirectional lead screw 202 on the inner wall of the rotating mounting frame 2 drives the load-bearing plate 203 to move, contact with the inner walls on both sides of the steel beam, and position it. At the same time, the limiting block 2031 is movably embedded in the limiting groove 201 to prevent tilting during movement. At the same time, the mounting frame 2 fixes the I-shaped block 204. The fastening bolt 2042 is threadedly embedded in the inner wall of the I-shaped block 204, and one end is embedded in the reserved hole of the steel beam to further strengthen the fixation. There is no need to adjust the position of the steel beam, which reduces the workload and is simple to operate. In addition, both ends of the spring 103 are respectively connected to the surfaces of the docking frame 1 and the connecting frame 104, providing a reset ability for the connecting frame 104. When the connecting frame 104 is pulled, the positioning pin 105 on the surface moves in the positioning hole 102 for limiting work. At the same time, when the positioning pin 105 disengages from the through hole 2041, the I-shaped block 204 slides in the limiting groove 201 to change the depth of the steel beam embedded in the docking frame 1, and then the I-shaped block 204 is fixed by the positioning pin 105, which is convenient to adjust the installation distance during installation and improves the applicability of docking.
