Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a truss support unloading device. Background Art

[0002] With the gradual development of building construction, long-span trusses are used more frequently. Due to the long length and large mass of long-span trusses, in order to facilitate the construction of trusses, in actual construction, trusses are generally spliced in segments. To facilitate the construction of trusses, a relatively common existing truss construction method is to use a hoisting device to hoist the segmented trusses onto the corresponding support frames and complete the welding of the segmented trusses in a stable support state.

[0003] After 5 bays of long-span trusses are welded, unified unloading is required, that is, the support frames are removed to release the support for the trusses. However, directly removing the support frames easily causes the long-span steel trusses to get out of control during unloading, thus triggering accidents. Summary of the Utility Model

[0027] In the prior art, large-span trusses are generally assembled by splicing in sections. The section trusses are hoisted onto the corresponding support frames by hoisting equipment, and the welding of the section trusses is completed in a stable support state. After 5 bays of the large-span truss are welded, unified unloading is required, that is, the support frames are removed to release the support for the truss. However, directly removing the support frames easily causes the large-span steel truss to get out of control during the unloading process, thus triggering accidents.

[0028] Therefore, this embodiment provides a truss support unloading device, which will not cause the large-span steel truss to get out of control during the process of removing the support frames and releasing the support for the truss, and has relatively high safety.

[0029] Please refer to Figures 1-3 , a truss support unloading device includes a support assembly and an unloading assembly, wherein the support assembly is used to support the truss 10, and the unloading assembly is arranged between the support assembly and the truss 10 for buffering and unloading to prevent out-of-control unloading.

[0030] The support assembly includes a support frame 11 and a support platform 12, wherein the support frame 11 is arranged on the roadbed box, and the support platform 12 is arranged on the top of the support frame 11.

[0031] Furthermore, guy ropes 20 can be connected to the top of the support frame 11, and the other ends of the guy ropes 20 are used to connect to the bottom of another adjacent support frame 11 to stabilize the support frame 11 and withstand the tensile force of the wind or the vertical wind load.

[0032] Optionally, please refer to Figure 2 and Figure 3 , guy ropes 20 can also be connected to both the top and bottom of the support frame 11. The other end of the guy rope 20 connected to the top of the support frame 11 is used to connect to the bottom of another adjacent support frame 11, and the other end of the guy rope 20 connected to the bottom of the support frame 11 is used to connect to the top of another adjacent support frame 11 to further stabilize the support frame 11 and improve the ability to withstand the tensile force of the wind or the vertical wind load.

[0033] Preferably, in this embodiment, a tightener 30 is installed on the guy rope 20. By pulling the wire winding wrench of the hand-operated ratchet tightener, the guy rope 20 is tightened. After the guy rope 20 is firmly clamped, the guy rope 20 can be slowly tightened to keep the guy rope 20 in a taut state, so that it can play the role of stabilizing the support frame 11 normally.

[0034] Furthermore, the support frame 11 includes a standard section 111 and a non-standard section 112. It should be noted that the height of the non-standard section 112 is determined according to actual needs, and the height of the non-standard section 112 is less than that of the standard section 111.

[0035] There are multiple standard sections 111, and the multiple standard sections 111 are connected in sequence from bottom to top in the vertical direction. When the height cannot meet the requirements at this time and exceeds the required height after connecting another standard section 111, the non-standard section 112 is connected to the topmost standard section 111 to control the height of the support frame 11 to meet the actual needs. The support platform 12 is arranged on the top of the non-standard section 112 to facilitate the installation of the unloading assembly.

[0036] Further, the unloading component includes an unloading member 21 and a jack 22. Specifically, the bottom of the unloading member 21 is fixedly provided on the support platform 12, and the top of the unloading member 21 abuts against the truss 10. The unloading member 21 is divided into several cutting segments along its height direction. During the unloading process, starting from the top, one cutting segment is cut each time to achieve hierarchical unloading of the truss 10. In addition, the jack 22 is arranged on the support platform 12 and abuts against the truss 10 to buffer when the truss 10 suddenly loses support, thereby realizing unloading buffering.

[0037] Optionally, the unloading member 21 is welded to the support platform 12.

[0038] For the truss support unloading device provided in this embodiment, an unloading member 21 and a jack 22 are arranged between the support platform 12 and the truss 10. Starting from the top, one cutting segment is cut each time to hierarchically unload the support of the support frame 11 for the truss 10. The truss 10 drops slightly, and the jack 22 is adjusted in real time to abut against the truss 10 until after cutting a plurality of cutting segments, the truss 10 is completely separated from the unloading member 21 and there is no out-of-control situation. At this time, the unloading jack 22 is removed, and further the support frame 11 is removed to complete the unloading process.

[0039] Further, the length and width of the unloading member 21 are 150 mm, and the height is 500 mm. The height of the cutting segment is 3 - 6 mm. In this embodiment, the height of each cutting segment is 5 mm.

[0040] Further, the support component further includes two limit columns 13. The two limit columns 13 are both arranged on the support platform 12, and the truss 10 is limited between the two limit columns 13. The limit of the truss 10 is completed by arranging the limit columns 13.

[0041] Specifically, first, one of the limit columns 13 is arranged on the support platform 12, the truss 10 is erected on the support platform 12 and abuts against the one limit column 13 to realize the positioning of the truss 10. Further, the other limit column 13 is arranged on the support platform 12 and abuts against the opposite side of the truss 10. The truss 10 is clamped between the two limit columns 13, thereby realizing the limit of the truss 10.

[0042] Preferably, the two limit columns 13 are both welded to the support platform 12.

[0043] A truss support unloading device provided in this embodiment first installs the support frame 11, the support platform 12, the unloading member 21, the jack 22 and one of the limit columns 13 in place, hoists and positions the truss 10. After the truss 10 abuts against the limit column 13 and is installed in place, the other limit column 13 is then installed in place. After 5 bays of the truss 10 are welded, unified unloading is carried out. The cutting sections are cut sequentially from top to bottom to achieve hierarchical unloading, and the height of the cutting section is 5 mm. It should be noted that after each cutting section is cut, the jack 22 is used for slow unloading until the truss 10 is completely separated. After it is stable, the support frame 11 is removed uniformly.

[0044] A truss support unloading device provided in this embodiment is convenient for on-site construction, installation and demolition, and can effectively prevent the large-span truss 10 from getting out of control during unloading, making it more stable and reliable during unloading.
