Description

Technical Field

[0001] The utility model relates to the technical field of steel structure buildings, in particular to a truss dispersed web support structure based on a large-span steel structure building. Background Art

[0002] Steel structure trusses refer to trusses made of steel. Steel trusses are often used as the main load-bearing components in roof structures, crane beams, bridges and hydraulic gates of industrial and civil buildings. Various towers, such as mast towers, TV towers and transmission line towers, often use spatial steel trusses composed of three-sided, four-sided or multi-sided plane trusses.

[0003] At present, most of the steel structure trusses are installed in outdoor venues, with large spans and generally high heights, so they are easily affected by vibrations, which destroys the stability of the truss support. Therefore, a truss distributed web support structure based on large-span steel structure buildings is proposed. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies of the prior art, the utility model provides a truss-type distributed web support structure based on a large-span steel structure building, which solves the problems raised in the above-mentioned background technology.

[0006] (II) Technical solution

[0007] To achieve the above purpose, the utility model is implemented through the following technical solutions: a truss distributed web support structure based on a large-span steel structure building, including a truss, a distributed web provided in the truss, a base provided below the truss, a transverse plate provided on the base that can drive the truss to move up and down, an adjustment plate provided on the base that can drive the transverse plate to move up and down, a support structure connected to the adjustment plate and capable of supporting the distributed webs in the truss, and a buffer structure capable of buffering the up and down displacement of the adjustment plate provided in the base. The support structure can be used to support the truss and guide the wind blowing from the truss. The buffer structure is provided to cooperate with the support structure, and can absorb the shock waves caused by the wind, thereby helping to strengthen the connection strength, stability and safety of the truss.

[0008] Furthermore, the support structure includes a hollow tube, a support plate connected to the hollow tube is provided on the hollow tube, and a guide plate that can be connected to the hollow tube is provided on the outside of the truss, and the guide plate can be connected to the adjustment plate.

[0009] Furthermore, the guide plate is provided with a guide groove for guiding wind, the guide plate can be connected to the hollow tube by bolts, a vertical rod is provided below the guide plate and is hollowly mounted with the cross plate and connected to the adjustment plate, and the support plate can contact the web at the top of the truss.

[0010] Furthermore, the guide plates are symmetrically arranged on both sides of the truss, the uprights are symmetrically arranged on both sides of the truss, the uprights are linearly arrayed below the guide plates, the guide grooves are linearly arrayed in the guide plates, and the cross-sectional shape of the guide plates is similar to a "ㄑ" shape. This shape is used to guide the wind direction to move, and then the wind guided by the wind guide grooves interacts with the directly blowing wind, which can lead to partial cancellation of the wind, thereby reducing the overall wind speed or changing the wind direction.

[0011] Furthermore, a displacement bar capable of moving up and down along a slide groove of the base is provided in the base, a support rod capable of connecting with an adjustment plate is provided on the displacement bar, and a space is left between the adjustment plate and the cross plate.

[0012] Furthermore, an extension platform connected to the base is provided on the outside of the base, and a synchronous driving member that can be connected to the adjustment plate and can drive the adjustment plate to move up and down is provided on the extension platform, and a guide rod that can guide the up and down displacement of the adjustment plate is provided on the extension platform.

[0013] Furthermore, the synchronous driving member is a synchronous driving cylinder, the bases are symmetrically distributed below the adjustment plate, and the outsides of the two bases are provided with extension platforms connected to the bases.

[0014] Furthermore, the buffer structure includes a connecting rod, the connecting rod is provided with a telescopic hydraulic rod that can be connected to the adjustment plate, the connecting rod is provided with a ring that is hollowly arranged with the connecting rod, and the ring is provided with an adjustable telescopic rod that can be connected to the output end of the telescopic hydraulic rod.

[0015] Furthermore, the two ends of the connecting rod are respectively connected to two bases, the rings are symmetrically arranged at the two ends of the connecting rod, and the two ends of the connecting rod are hollowly sleeved with a first return spring connected to the ring and elastically returning. One end of the adjustable telescopic rod is connected to the output end of the telescopic hydraulic rod through a rotating shaft, and the other end of the adjustable telescopic rod is connected to the ring through a rotating shaft. The adjustable telescopic rod is hollowly sleeved with a long return spring that can be connected to the rotating shaft on the telescopic hydraulic rod and elastically returning. The output end of the telescopic hydraulic rod is hollowly sleeved with a short return spring that can be connected to the rotating shaft on the telescopic hydraulic rod and elastically returning.

[0016] Compared with the prior art, the truss-type distributed web support structure based on the large-span steel structure building has the following advantages:

[0017] 1. The support structure can not only strengthen the connection strength of the truss, but also further guide the direction of the wind. The wind guided by the wind guide groove can interact with the directly blowing wind, which can lead to partial cancellation of the wind, thereby reducing the overall wind speed or changing the wind direction, thereby improving the stability of the truss to a certain extent.

[0018] 2. With the cooperation of the buffer structure and the supporting structure, the wind is guided by the guide plate to move along the guide groove, so that part of the wind energy is guided to the adjustment plate, which will bring a certain downward pressure to the adjustment plate to a certain extent. At this time, the stable strength of the overall structure can be guaranteed, and the buffer structure can also absorb the shock waves generated by the adjustment plate and the overall structure when they are subjected to wind and other forces, thereby avoiding the overall structure from being affected by vibration.
