Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, and in particular to load-bearing beams and installation structures. Background Technology

[0002] As the main beam of the bridge support system, the load-bearing crossbeam is used to bear the load of the upper truss beam and transfer the entire upper load to the columns. Its safety and reliability are of paramount importance. Due to the large load it bears, a single I-beam section beam usually cannot meet the requirements. At present, the load-bearing beam of the support often adopts double or triple I-beam section box beams, and the I-beams are spliced ​​together by welding. Due to the limitations of raw materials and transportation size, the longest single beam can reach 12m. However, in actual use, the length requirements of the load-bearing beam are diverse, and the existing rated size is difficult to meet the requirements. Therefore, cutting and welding are required in the actual construction process, which increases the difficulty of welding, the degree of danger, and the welding quality cannot be guaranteed.

[0003] There are still many problems with the welding method. When the load-bearing beam is very long, it is not possible to lift the whole beam at once on site. It is necessary to lift it into place in sections and then weld it to extend it. At this time, the load-bearing beam is in the air. When the load-bearing beam is no longer in use and needs to be dismantled and transported, it is necessary to cut the load-bearing beam at high altitude and then dismantle it in sections and lift it down. The whole process is difficult to operate, inefficient, has a lot of material waste, and the construction quality cannot be guaranteed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a prefabricated load-bearing beam to overcome the shortcomings of the existing technology.

[0005] The technical solution adopted by this utility model is as follows: a load-bearing beam, including a crossbeam, one end of which is provided with a male connector and the other end of which is provided with a female connector, the male connector and the female connector are convex and concave, and the male connector and the female connector are respectively provided with mounting holes; one end of the crossbeam is provided with a protrusion extending outward, and the other end of the crossbeam is provided with a recessed notch; the upper and lower surfaces of the male connector and the upper and lower surfaces of the female connector do not exceed the upper and lower surfaces of the crossbeam.

[0006] The crossbeam has a male connector and a female connector at one end and a male connector and a female connector at the other end. The male connectors and female connectors at both ends of the crossbeam are respectively corresponding and located on the same axis.

[0007] The crossbeam has a protrusion extending outward and a recessed slot at each end, with the protrusion and slot corresponding to each other and on the same axis.

[0008] The crossbeam includes an upper flange, a lower flange, a web plate located in the middle of the upper flange and the lower flange and fixedly connected to the upper flange and the lower flange, and end plates respectively located at both ends of the web plate.

[0010] The protrusion and the gap are respectively provided on the upper wing plate or the lower wing plate.

[0011] The upper wing plate and the lower wing plate extend beyond the end plate but do not exceed the center of the mounting hole of the male connector or connector.

[0012] An installation structure for a load-bearing beam includes two or more load-bearing beams connected sequentially. After the male and female connectors are mated, they are inserted into the mounting holes using pins, with the protrusions within the gaps.

[0013] When the protrusion and the void are matched, the mounting holes of the male connector and the female connector are aligned.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 3As shown, the load-bearing beam described in this embodiment includes a crossbeam 1. One end of the crossbeam 1 is provided with a male connector 2, and the other end of the crossbeam 1 is provided with a female connector 3. The male connector 2 and the female connector 3 are convex and concave, and each of the male connector 2 and the female connector 3 is provided with a mounting hole 0, preferably two mounting holes. One end of the crossbeam 1 is provided with a protrusion 11 extending outward, and the other end of the crossbeam 1 is provided with a recessed slot 10. The upper and lower surfaces of the male connector 2 and the upper and lower surfaces of the female connector 3 do not exceed the upper and lower surfaces of the crossbeam 1. In this embodiment, the load-bearing beam has a female connector 3 and a male connector 2 at both ends, and also a protrusion 11 and a slot 10 at both ends. When the two load-bearing beams are joined, the female connector 3 and the male connector 2 are convex and concave, and the protrusion 11 falls into the slot 10, which is also convex and concave. At the same time, the mounting hole 0 of the female connector 3 corresponds to the mounting hole 0 of the male connector 2. At this time, inserting a pin into the mounting hole 0 can achieve extended assembly. The upper and lower surfaces of the male connector 2 and the female connector 3 do not exceed the upper and lower surfaces of the crossbeam 1. When the two load-bearing beams are joined together, the surface of the load-bearing beam is aligned with the crossbeam 1.

[0020] In a preferred embodiment, one end of the crossbeam 1 is provided with a male connector 2 and a female connector 3, and the other end of the crossbeam 1 is also provided with a male connector 2 and a female connector 3. The male connectors 2 and female connectors 3 at both ends of the crossbeam 1 correspond to each other and are on the same axis. In this embodiment, both ends of the crossbeam 1 are provided with male connectors 2 and female connectors 3, and the male connectors 2 and female connectors 3 at both ends of the crossbeam 1 correspond to each other and are on the same axis. Therefore, when two load-bearing beams are joined together, it is not necessary to distinguish between the front and back to achieve a mating connection.

[0021] In a preferred embodiment, the two ends of the crossbeam 1 are respectively provided with an outwardly extending protrusion 11 and an inwardly recessed slot 10, with the protrusion 11 and slot 10 corresponding to each other and located on the same axis. In this embodiment, the protrusion 11 and slot 10 are on the same axis, resulting in a neat appearance after installation.

[0022] In a preferred embodiment, the crossbeam 1 includes an upper flange 12, a lower flange 13, a web 14 located in the middle of the upper flange 12 and the lower flange 13 and fixedly connected to the upper flange 12 and the lower flange 13, and end plates 15 respectively disposed at both ends of the web 14. The male connector 2 and the female connector 3 are respectively fixedly connected to the end plates 15. In this embodiment, the end plates 15 provide a large installation area for the male connector 2 and the female connector 3, and the female connector 3 and the male connector 2 are stable and have good strength after installation.

[0023] In a preferred embodiment, reinforcing plates 16 are provided on both sides of the web plate 14, and the reinforcing plates 16 are fixedly disposed between the upper wing plate 12 and the lower wing plate 13.

[0024] In a preferred embodiment, the protrusion 11 and the notch 10 are respectively provided on the upper wing plate 12 or the lower wing plate 13. The protrusion 11 and the notch 10 are formed on the upper wing plate 12 or the lower wing plate 13, and are in a visually observable position during assembly. They serve as guides for the male connector 2 and the female connector 3 to mate, making installation convenient.

[0025] In a preferred embodiment, the upper wing plate 12 and the lower wing plate 13 extend beyond the end plate 15 but do not exceed the center of the mounting hole 0 of the male connector 2 or the connector. In this embodiment, the upper wing plate 12 and the lower wing plate 13 cover part of the connector. After the two load-bearing beams are joined together, the two ends of the upper wing plate 12 or the lower wing plate 13 on the two load-bearing beams are spliced ​​together, thereby covering the connector.

[0026] An installation structure for load-bearing beams includes the aforementioned load-bearing beams, with two or more beams connected sequentially. After the male connector 2 and female connector 3 are mated, a pin 5 is inserted into the mounting hole 0, and the protrusion 11 is within the gap 10. Preferably, when the protrusion 11 and the gap 10 are mated, the mounting holes 0 of the male connector 2 and the female connector 3 are aligned. That is, when the protrusion 11 and the gap 10 are mated, excluding the assembly gap, the two mounting holes 0 are concentric. At this point, the pin can be installed, and the alignment and installation of the male connector 2 and female connector 3 can be achieved by observing the positions of the protrusion 11 and the gap 10.
