Description

Technical Field

[0001] The present application relates to the technical field of steel trestle installation structures, and in particular to a steel trestle sliding support structure. Background Art

[0002] A steel trestle is a temporary bridge with a simple structure that is easy to build and dismantle. It is usually used to solve short-term traffic problems. For example, in the application of shallow silos, a steel trestle is erected between two adjacent groups of shallow silos, making it easier for workers to move between the two adjacent groups of shallow silos via the steel trestle.

[0003] In the application of existing steel trestles in shallow silos, the steel trestles usually include a bridge body and two sets of fixed supports; among them, the two sets of fixed supports are respectively fixedly set on the side close to each other of two adjacent shallow silos, and both ends of the bridge body are respectively fixedly set on the top of the two sets of fixed supports by welding / bolt connection, so that the two sets of fixed supports form a supporting effect on the bridge body, making it convenient for workers to move between the two adjacent shallow silos through the bridge body.

[0004] However, due to factors such as foundation settlement / shallow silo structure deformation, tensile / compressive stress may be generated on the bridge body between two adjacent groups of shallow silos. Although the bridge body made of steel structure has certain tensile / compressive deformation characteristics, the tensile / compressive deformation process will also cause the stability of the bridge structure to decrease, thereby reducing the service life of the steel trestle.

[0022] The following is combined with Figures 1 to 4 This application is described in further detail.

[0023] The application discloses a steel trestle sliding support structure.

[0024] Reference Figure 1 The steel trestle sliding support structure includes a shallow circular silo 1 and a steel trestle 2, that is, the steel trestle 2 is specifically used in the shallow circular silo 1, which makes it convenient for staff to move and carry out work between two adjacent groups of shallow circular silos 1 through the steel trestle 2.

[0025] There are two groups of shallow silos 1, which are arranged at intervals. The interval between the two groups of shallow silos 1 is slightly smaller than the overall length of the steel trestle 2. The steel trestle 2 is connected between the two groups of shallow silos 1 in a slightly inclined arrangement.

[0026] Reference Figure 2-4 The steel trestle 2 specifically includes a first fixed support 21, a second fixed support 22 and a bridge body 23; wherein the first fixed support 21 and the second fixed support 22 both adopt the steel frame bracket structure in the existing technology as the fixed support, which is fixed to the top of the shallow silo 1 by partially embedded / explosive bolts, etc. Specifically, the first fixed support 21 and the second fixed support 22 are respectively fixed on the side close to each other on the top of the two groups of shallow silos 1; the bridge body 23 adopts the steel frame bridge structure in the existing technology, and the bridge body 23 is arranged slightly inclined. The end of the bridge body 23 with a relatively low height is fixedly provided with a connecting support 24 by welding. The connecting support 24 is fixedly provided on the top of the first fixed support 21 by welding / bolt connection. The end of the bridge body 23 with a relatively high height is fixedly provided with a sliding support 25 by welding. A connecting component 3 and a limit component 4 are provided between the sliding support 25 and the second fixed support 22 to provide a relative sliding space between the sliding support 25 and the second fixed support 22.

[0027] By connecting the components 3 and the limiting components 4, a relative sliding space is provided between the sliding support 25 and the second fixed support 22. If there is a slight change in the distance between two adjacent groups of shallow silos 1 due to factors such as foundation settlement / structural deformation of the shallow silo 1, the relative sliding between the sliding support 25 and the second fixed support 22 can reduce the tensile / compressive stress on the bridge body 23, and minimize the reduction in structural stability of the bridge body 23 due to tensile / compressive deformation, thereby increasing the service life of the steel trestle 2.

[0028] In addition, a polytetrafluoroethylene plate 5 is provided between the sliding support 25 and the second fixed support 22. Two groups of polytetrafluoroethylene plates 5 are configured, and the two groups of polytetrafluoroethylene plates 5 are superimposed on each other and arranged between the sliding support 25 and the second fixed support 22. When the bridge body 23 is subjected to vibration, the polytetrafluoroethylene plate 5 can effectively isolate the vibration transmission.

[0029] In this embodiment, there are four groups of connecting components 3 arranged between the sliding support 25 and the second fixed support 22. The four groups of connecting components 3 are distributed in a rectangular array, and the four groups of connecting components 3 all pass through the second fixed support 22, the polytetrafluoroethylene plate 5 and the sliding support 25 in sequence.

[0030] The connecting assembly 3 specifically includes a connecting screw 31, a connecting gasket 32 and a connecting nut 33; wherein, the second fixed support 22 is penetrated by a circular connecting hole 34, and the polytetrafluoroethylene plate 5 and the sliding support 25 corresponding to the connecting hole 34 are penetrated by strip holes 35 extending along the length direction of the bridge body 23. The connecting screw 31 penetrates the connecting hole 34, two groups of strip holes 35 and the connecting gasket 32 from bottom to top in sequence, and the connecting nut 33 is threadedly connected to the connecting screw 31 to make the connecting gasket 32 fit the sliding support 25.

[0031] In this embodiment, there are two groups of limit assemblies 4 disposed between the sliding support 25 and the second fixed support 22 . Both groups of limit assemblies 4 are fixedly disposed on the second fixed support 22 , and the two groups of limit assemblies 4 slide and fit with both sides of the sliding support 25 , respectively.

[0032] The limiting component 4 specifically includes a fixing portion 41 and a limiting portion 42; wherein, the fixing portion 41 is fixedly arranged on the top of the second fixed support 22 by welding, and the limiting portion 42 is integrally formed and vertically fixed on the side of the fixing portion 41 close to the sliding support 25, and the limiting portion 42 is slidably fitted with the sliding support 25, and at the same time, the limiting portion 42 is fitted with the polytetrafluoroethylene plate 5.

[0033] The sliding support 25 is limited in the vertical direction by four groups of connecting components 3, and the sliding support 25 is limited in the width direction of the bridge body 23 by two groups of limiting components 4, so that the bridge body 23 can only have a slight sliding freedom along its length direction. The specific sliding depends on the length of the strip hole 35, so that a relative sliding space is provided between the sliding support 25 and the second fixed support 22 through the connecting components 3 and the limiting components 4.

[0034] In this embodiment, the sliding support 25 specifically includes a base plate 251, a vertical plate 252 and a horizontal plate 253. The above-mentioned strip hole 35 is provided at the position of the base plate 251 corresponding to the connection hole 34. The vertical plate 252 and the horizontal plate 253 are both integrally formed and vertically fixed on the side of the base plate 251 away from the second fixed support 22, and the vertical plate 252 and the horizontal plate 253 are arranged perpendicular to each other and integrally formed. The bridge body 23 is welded and fixed on the end of the vertical plate 252 and the horizontal plate 253 away from the base plate 251.

[0035] In this embodiment, the bridge body 23 is arranged at an angle, and the angle between the bridge body 23 and the horizontal plane is between 4-8 degrees. Specifically, the angle between the bridge body 23 and the horizontal plane is 6 degrees.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be covered within the scope of protection of the present application.
