[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in an embodiment of the utility model, a beam connection structure 300 is provided, which includes a first beam body 100, a second beam body 200, a connection structure 300 and a reinforcement structure 400, wherein the second beam body 200 is arranged on one side of the first beam body 100; the connection structure 300 includes a first connection portion 310 arranged at the end of the first beam body 100, a second connection portion 320 arranged at the end of the second beam body 200, and a plurality of fasteners 330, wherein the first connection portion 310 and the second connection portion 320 are abutted against each other, and each fastener 330 is arranged along the extension direction of the first beam body 100 and connects the first connection portion 310 and the second connection portion 320; the reinforcement structure 400 includes a plurality of first reinforcement members 410 arranged between the first beam body 100 and the first connection portion 310, and a plurality of second reinforcement members 420 arranged between the second beam body 200 and the second connection portion 320, wherein the first reinforcement members 410 and / or the second reinforcement members 420 are arranged alternately with the fasteners 330.

[0034] On the whole, when the inter-beam connection structure 300 is in use, the first beam body 100 and the second beam body 200 are connected by the connection structure 300 to form an integrated structure. By setting the first connection part 310 at the end of the first beam body 100 and the second connection part 320 at the end of the second beam body 200, the first connection part 310 and the second connection part 320 are used to improve the structural strength of the first beam body 100 and the second beam body 200 at the connection node, which is also beneficial to improve the docking efficiency between the first beam body 100 and the second beam body 200. The first connection part 310 and the second connection part 320 also provide installation positions for the fasteners 330, which improves the flexibility of the arrangement of the fasteners 330, helps to avoid the redundancy of the fasteners 330, thereby reducing manufacturing costs and improving economy.

[0035] Furthermore, by arranging each fastener 330 along the extension direction of the first beam body 100, when the first beam body 100 and the second beam body 200 are subjected to a shear force perpendicular to the beam body, the fastener 330 can be pulled along its axial direction, so that the fastener 330 can fully exert its anti-bending effect, thereby increasing the anti-bending bearing capacity at the connection nodes between the beams, so as to better meet the high bearing capacity requirements when assembling large-span beams in sections.

[0036] The utility model can be widely applied to assembled steel structure projects, significantly improves the bending resistance of connecting nodes between beams, and each component can be standardized and scaled, with high assembly efficiency and obvious social and economic benefits.

By staggered intervals between the first reinforcement members 410 and the fasteners 330, the structural strength between the first beam body 100 and the first connecting portion 310 can be strengthened in sections by using the adjacent first reinforcement members 410, which is beneficial to reducing the deformation of the first connecting portion 310 during use, thereby significantly improving the connection stability of each fastener 330.

[0038] In another embodiment of the present invention, the second reinforcement members 420 and the fasteners 330 are arranged at staggered intervals. By staggering the second reinforcement members 420 and the fasteners 330, the structural strength between the second beam body 200 and the second connecting portion 320 can be strengthened in sections by using the adjacent second reinforcement members 420, which is conducive to reducing the deformation of the second connecting portion 320 during use, thereby significantly improving the connection stability of each fastener 330.

[0043] Furthermore, the designer can adjust the number of beams according to the use requirements, and no specific limitation is made here. By using the beam connection structure 300, adjacent beams can be quickly connected at the use site to form beams of different lengths, thereby improving installation efficiency.

[0045] In a specific embodiment, the first end plate 311 and the second end plate 321 are configured to have the same shape and structure. When the first end plate 311 and the second end plate 321 are abutted and overlapped, the end of the first beam body 100 and the end of the second beam body 200 can be symmetrically distributed on both sides of the gap between the first end plate 311 and the second end plate 321, achieving a better positioning and docking effect.

[0046] Further, the projection of the end of the first beam body 100 in the extension direction of the first beam body 100 is located in the first end plate 311 and / or the projection of the end of the second beam body 200 in the extension direction of the second beam body 200 is located in the second end plate 321 .

[0049] Similarly, by making the projection of the second beam body 200 in the extension direction located within the second end plate 321, the size of the second end plate 321 is made larger than the end of the second beam body 200, so that the end of the second beam body 200 can be fully connected to the second end plate 321, thereby improving the connection strength between the second beam body 200 and the second end plate 321.

[0050] Furthermore, a plurality of fasteners 330 may be provided at the portions of the first end plate 311 and the second end plate 321 protruding from the beam body, thereby facilitating increasing the flexibility of arranging the fasteners 330 .

[0051] In order to further improve the bending resistance of the inter-beam connection structure 300, the size of the upper end and / or lower end of the first end plate 311 may be larger than the middle size of the first end plate 311, which is conducive to setting more fasteners 330 at the upper end and / or lower end of the first end plate 311.

[0052] Preferably, the size of the upper end and the lower end of the first end plate 311 are larger than the size of the middle part of the first end plate 311, and the upper end of the first end plate 311 and the lower end of the first end plate 311 are symmetrically arranged in the height direction, so that the upper end of the first end plate 311 and the lower end of the first end plate 311 can be provided with the same number of fasteners 330. In addition, the second end plate 321 is provided with the same shape as the first end plate 311, so as to meet the installation requirements of each fastener 330.

[0053] Designers can adjust the specific structures of the first end plate 311 and the second end plate 321 according to the use requirements, and no specific limitation is made here. Preferably, the first end plate 311 and the second end plate 321 are both configured in an I-shape.

[0054] In the implementation mode of the present utility model, Figure 3 and Figure 4In the illustrated embodiment, the fastener 330 includes a connecting bolt 331 and two connecting nuts 332 threadedly connected to the connecting bolt 331. The first end plate 311 and the second end plate 321 are both provided with a plurality of mounting holes for the connecting bolts 331 to pass through. The connecting bolts 331 are passed through the corresponding mounting holes and are fastened to the first end plate 311 and the second end plate 321 by the two connecting nuts 332.

[0055] Of course, in other feasible embodiments, designers can adjust the specific structure of the fastener 330 according to usage requirements. For example, the fastener 330 can be set as a connecting screw, etc., and no specific limitation is made here.

[0056] In the embodiment of the present invention, a plurality of connection bolts 331 are disposed at intervals around the end of the first beam body 100 , and connect the first end plate 311 and the second end plate 321 .

[0057] By arranging a plurality of connection bolts 331 at intervals around the end of the first beam body 100 , the connection bolts 331 can be distributed more evenly, which is beneficial to improving the connection reliability of the first end plate 311 and the second end plate 321 .

[0058] Designers can adjust the number and arrangement of the connecting bolts 331 according to usage requirements, and no specific restrictions are made here.

[0059] In the embodiment of the present invention, the first reinforcement member 410 includes a first stiffening rib, which is disposed along the extension direction of the first beam body 100 and connects the first beam body 100 and the first connecting portion 310 .

[0060] By arranging the first stiffening rib along the extension direction of the first beam body 100, when the first beam body 100 and the second beam body 200 are subjected to a shear force perpendicular to the beam bodies, the first stiffening rib can reinforce the first beam body 100 and the first end plate 311 along its axial direction, so that the first stiffening rib can fully play a reinforcing role, thereby improving the structural strength between the first beam body 100 and the first end plate 311.

[0061] Furthermore, the second reinforcement member 420 includes a second stiffening rib, which is disposed along the extension direction of the second beam body 200 and connects the second beam body 200 and the first connecting portion 310 .

[0062] By arranging the second stiffening ribs along the extension direction of the second beam body 200, when the first beam body 100 and the second beam body 200 are subjected to a shear force perpendicular to the beam bodies, the second stiffening ribs can reinforce the second beam body 200 and the second end plate 321 along their axial direction, so that the second stiffening ribs can fully play a reinforcing role, thereby improving the structural strength between the second beam body 200 and the second end plate 321.

[0063] In a specific embodiment, the first beam body 100 is an I-beam, and first stiffening ribs are provided on the upper and lower end surfaces of the upper plate of the first beam body 100, and first stiffening ribs are also provided on the upper and lower end surfaces of the lower plate of the first beam body 100.

[0065] In the embodiment of the present invention, each first reinforcement member 410 and each second reinforcement member 420 are symmetrically arranged with respect to the gap between the first connection portion 310 and the second connection portion 320 .

[0066] By symmetrically arranging the first reinforcement members 410 and the second reinforcement members 420, the first reinforcement members 410 and the second reinforcement members 420 can have the same reinforcement effect, so that the first beam body 100 and the first end plate 311 and the second beam body 200 and the second end plate 321 have the same structural strength, which reduces the difficulty of processing and manufacturing. In particular, when facing multiple sections of beam bodies, any two adjacent sections of beam bodies can be connected through the beam connection structure 300 without considering the position sequence of the beam bodies, which has better applicability.
