AI Technical Summary
Under the action of external forces such as wind loads or earthquakes, the steel corridors of existing industrial plants will produce vertical displacement differences, resulting in the left and right simple supports being unable to withstand vertical loads, which may lead to damage to the connection structure.
A high-altitude steel corridor of industrial factory buildings with bidirectional sliding support is designed. The two ends of the steel beam are overlapped on the cow legs, and a simple support at the left end and a bidirectional sliding support are provided. The bidirectional sliding support is vertically moved through the connecting beam, and the concrete baffle prevents slipping out.
Through the vertical movement of the bidirectional sliding support, the load caused by vertical displacement difference can be adapted to prevent damage to the connecting corridor structure, and at the same time ensure the stability of the connecting structure.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building corridors, and particularly relates to an industrial plant high-altitude steel corridor with a bidirectional sliding support. Background Art
[0002] In industrial parks, concrete factories are often connected by corridors due to functional requirements. The span is generally between 15m and 20m. Due to the high height, the locations where structural columns can be set are usually in fire escapes. Generally, a simply supported steel beam + reinforced truss floor deck structure is adopted. This form is convenient for high-altitude lifting and construction, and no high-altitude formwork is required. The two ends of the steel beam are supported on the corbel supports reserved for the structural columns of the concrete factory.
[0003] Conventional treatment of steel beam supports Figure 1 As shown, it includes a left-end simple support 20, a right-end simple support 30 or a horizontal sliding support. However, under the action of external forces such as wind loads or earthquakes, a vertical displacement difference will occur between these two monomers. Since the left and right simple supports cannot withstand the vertical load, their connection structure may also be damaged in this case. Utility Model Content
[0004] The utility model provides an industrial plant high-altitude steel corridor with a bidirectional sliding support, which solves the problems in the prior art.
[0005] The technical solution of the utility model is achieved in this way:
[0006] A high-altitude steel corridor of an industrial plant with a bidirectional sliding support comprises a steel beam arranged between two plants and a structural column for overlapping the steel beams. There are two groups of steel beams, which are arranged parallel to each other. Corbels are fixedly connected to the side walls of the structural columns, and the ends of the steel beams are overlapped on the upper ends of the corbels. Supports are also arranged between the steel beams and the corbels for sliding of the steel beams. The supports comprise a left-end simple support arranged on one side of the steel beam and a bidirectional sliding support on the other side. A connecting beam is also arranged perpendicular to the steel beam, and the bidirectional sliding support is also movably sleeved on the connecting beam to achieve vertical movement.
[0007] Furthermore, both ends of the connecting beam are cantilevered 500 mm.
[0008] Furthermore, concrete baffles are fixedly connected to both ends of the connecting beam to prevent the bidirectional sliding bearing from falling off the connecting beam.
[0009] Furthermore, the thickness of the concrete baffle is 300 mm.
[0010] Furthermore, the bidirectional sliding support includes a vertical support portion slidably connected to the connecting beam.
[0011] After adopting the above technical solution, the beneficial effects of the utility model are:
[0012] 1. In the utility model, by providing a two-way sliding support, the original right-end simple support is replaced with a two-way sliding support with a connecting beam, so that it can move in the vertical direction, thereby adapting to the load caused by the vertical displacement difference and preventing the connection structure of the corridor from being damaged.
[0013] 2. In the utility model, a connecting beam is provided, and the connecting beam is cantilevered 500mm outside, so that the bidirectional sliding support can slide freely in the vertical direction. At the same time, a concrete baffle is provided at the end of the connecting beam to prevent the bidirectional sliding support from sliding out of the range of the corbel.

[0019] 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 of 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.
[0020] Example: Figure 2-3As shown, an industrial plant high-altitude steel corridor with a bidirectional sliding support includes two parallel steel beams 10, and the two ends of the steel beam 10 are respectively fixedly connected between the two plant buildings. Figure 2 As shown, a structural column 70 is arranged on the side of the factory building, a corbel 80 is fixedly connected to the side wall of the structural column 70, and the steel beam 10 is overlapped at the upper end of the corbel 80. A support is arranged between the steel beam 10 and the corbel 80 for the steel beam 10 to slide. The support is divided into a left end simple support 20 on one side and a bidirectional sliding support 40 on the other side;
[0021] The left-end simple support 20 and the bidirectional sliding support 40 are both provided with an upper sliding support and a lower support fixedly mounted on the upper end of the corbel 80, so that the left and right ends of the steel beam 10 can slide horizontally and can adapt to lateral loads under special circumstances;
[0022] like Figure 3 As shown, the bidirectional sliding support 40 is also provided with a connecting beam 60, and the upper sliding support is also movably connected to the connecting beam 60, so that the sliding effect along the connecting beam 60 can be achieved. Figure 1 In the existing high-altitude steel corridor of an industrial plant, a right-end simple support 30 is arranged at the other end of the steel beam 10, and the bidirectional sliding support 40 can not only realize the lateral movement of the right-end simple support 30, but also can move vertically along the connecting beam 60. When encountering a vertical load caused by wind load or earthquake, the bidirectional sliding support 40 can move in the vertical direction to adapt to the vertical load;
[0023] The above structure can satisfy the horizontal sliding condition without limiting the relative movement in the vertical direction, and can avoid the connection damage caused by collision. In addition, the sliding support of the connecting beam 60 is added, and both ends of the connecting beam 60 are cantilevered 500mm, so that the bidirectional sliding support 40 can slide freely in the vertical direction.
[0024] In addition, Figure 3 As shown, in order to prevent the bidirectional sliding support 40 from sliding out of the range of the corbel 80 and also meet the requirements of the maximum offset distance of the vertical relative movement of the concrete structures at both ends, 300m concrete baffles 50 are provided at both ends of the connecting beam 60 to provide a second line of defense to further prevent the steel beam 10 from falling.
[0025] Therefore, when faced with vertical displacement differences, it can withstand the vertical loads caused by the displacement differences and ensure the stability of the connection structure.
[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
