DETAILED DESCRIPTION

[0022] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0023] The present application embodiment discloses a beam steel structure. Figure 1 and Figure 2 A crossbeam steel structure includes a crossbeam body 1, which is an I-beam. The crossbeam body 1 includes an upper wing plate 2, a lower wing plate 3 and a web plate 4. Both ends of the web plate 4 are provided with a bending portion 5, which extends along the length direction of the web plate 4 and is formed integrally with the web plate 4. The bending portion 5 protrudes from the ends of the upper wing plate 2 and the lower wing plate 3, and the bending directions of the bending portions 5 at both ends of the web plate 4 are oppositely arranged along the thickness direction of the web plate 4; and after the two adjacent bending portions 5 of the two crossbeam bodies 1 are attached to each other, the two web plates 4 on the two crossbeam bodies 1 are coplanar.

[0024] A plurality of fixing holes 6 are also provided on the bending portion 5, and the plurality of fixing holes 6 on the two adjacent bending portions 5 of the two beam bodies 1 are arranged in one-to-one correspondence, a fixing bolt 7 is passed through the fixing hole 6 of one of the bending portions 5, and a nut is matched with the fixing bolt 7; a positioning structure for positioning the two is provided between a bending portion 5 on one beam body 1 and a bending portion 5 on another beam body 1.

[0025] After such arrangement, when the two beam bodies 1 are to be spliced, the two beam bodies 1 can be directly lifted to a horizontal level, and the two bent portions 5 at the two adjacent ends of the two beam bodies 1 can be made to fit together. Since the bent portions 5 extend along the length direction of the web 4, the two bent portions 5 at the two ends of the two beam bodies 1 can fit together more freely; then the orientation of the beam body 1 is adjusted, and the two bent portions 5 can be pre-positioned with the help of the positioning structure on the two adjacent bent portions 5, and finally the multiple fixing holes 6 on the two bent portions 5 can be more conveniently aligned, which facilitates the penetration and locking of the fixing bolts 7, thereby reducing the installation difficulty when the beam bodies 1 are spliced, and facilitating operations at high altitudes to improve construction efficiency.

[0026] In one possible embodiment, referring to Figure 1 and Figure 2 The positioning structure includes a plurality of positioning pins 81 and a plurality of positioning long holes 82. When the positioning pins 81 are fixedly connected to the bending portion 5 at one end of the beam body 1, the positioning long holes 82 are opened on the bending portion 5 at the other end of the beam body 1, and the positioning pins 81 are plugged and matched with the positioning long holes 82.

[0027] At the same time, when the two beam bodies 1 are completely spliced, the multiple positioning pins 81 on the two adjacent bending parts 5 are aligned one by one with the multiple positioning long holes 82. In addition, the positioning pins 81 are fixedly connected with an anti-slip block 83 whose size is larger than the width of the long hole. The anti-slip block 83 is arranged at the end of the positioning pin 81 away from the bending part 5, and a through hole 84 connected to the positioning long hole 82 is also opened on the bending part 5 where the positioning long hole 82 is opened. The through hole 84 is plugged and adapted with the anti-slip block 83. In the specific assembly, the beam body 1 should be adjusted so that the through hole 84 is located at the lower side of the long hole.

[0028] After such arrangement, when adjusting the positions of the two bending parts 5, first align the multiple positioning pins 81 on one bending part 5 with the multiple through holes 84 on the other bending part 5 one by one, and then affix the two bending parts 5 so that the anti-slip block 83 on the positioning pin 81 passes through the through hole 84, and then, lift up the bending part 5 with the positioning pin 81 so that the positioning pin 81 slides into the positioning long hole 82. On the one hand, the two bending parts 5 can be accurately fitted together, and on the other hand, the two bending parts 5 can be prevented from separating from each other after being fitted together. Therefore, with the help of multiple positioning pins 81 and positioning long holes 82, the positioning and limitation of the splicing of the beam body 1 can be played, thereby reducing the installation difficulty of the splicing of the beam body 1.

[0029] In another possible embodiment, referring to Figure 3 Specifically, the positioning structure is located on the side wall of the web 4 on the beam body 1 at one end of which the bending portion 5 is provided, and the positioning structure includes a socket 85 and a tenon 86 arranged on both sides of the web 4, and a slot 87 for the tenon 86 to be inserted is provided on the socket 85, the tenon 86 is fixedly connected to the end of the bending portion 5 away from the beam body 1, and the socket 85 is fixedly connected to the end of the web 4 close to the bending portion 5; and when the two beam bodies 1 are completely spliced, the tenon 86 on one beam body 1 is plugged and connected with the adjacent slot 87 on the other beam body 1, and the slot 87 on the beam body 1 is embedded in the tenon 86 on the other beam body 1. The free end of the tenon 86 is also provided with a reduced diameter portion 88.

[0030] After such arrangement, when adjusting the orientation of the two bending parts 5, the two beam bodies 1 are first aligned horizontally, and then the tenons 86 and slots 87 on the bending parts 5 of the beam bodies 1 are plugged into each other. This not only allows the two beam bodies 1 to be tightly connected together for pre-positioning, but also prevents the two beams from moving vertically and separating after the pre-positioning, thereby enhancing the stability of the structure of the two beam bodies 1 after pre-assembly.

[0031] Furthermore, in order to strengthen the protruding bent portion 5 of the web 4, refer to Figure 1 The side wall at one end of the bent portion 5 of the web 4 is also fixedly connected to a reinforcing plate 9 arranged along the length direction of the web 4. The specific connection method can be welding or bolting, and the width of the reinforcing plate 9 is equal to the width of the web 4 and the length is greater than the length of the bent portion 5.

[0032] After such arrangement, when the bending portion 5 is subjected to load and exerts shear force, a reinforcing plate 9 with the same width and longer than the bending portion 5 is installed on the side wall of one end of the bending portion 5 of the web 4. The reinforcing plate 9 disperses the pressure borne by the bending portion 5, and the arrangement of the reinforcing plate 9 strengthens the structure and further reinforces the bending portion 5, so that the bending portion 5 can play a stable and effective load-bearing role as much as possible.

[0033] The implementation principle of a beam steel structure in the embodiment of the present application is:

[0034] When splicing the two beam bodies 1, the two beam bodies 1 can be directly lifted to a horizontal level, and the two bent portions 5 at the two adjacent ends of the two beam bodies 1 can be placed against each other. Since the bent portions 5 extend along the length direction of the web 4, the two bent portions 5 at the two ends of the two beam bodies 1 can be placed against each other more freely; then the orientation of the beam body 1 is adjusted, and the two bent portions 5 can be pre-positioned by means of the cooperation of the locating pins 81 and the locating long holes 82 on the two adjacent bent portions 5 or the cooperation of the sockets 85 and the tenons 86, so that the multiple fixing holes 6 on the two bent portions 5 can be more conveniently aligned, which facilitates the penetration and locking of the fixing bolts 7, thereby reducing the installation difficulty when splicing the beam bodies 1, and facilitating operations at high altitudes to improve construction efficiency.
