Embodiment 1

[0088] Please refer to the attached Figure 1~3 , with Figure 1~3 The elevation view, installation front view and left view of a simply supported bridge telescopic device with multi-directional rotation at both ends provided in Embodiment 1 of the present application. As shown in the figure, the bridge telescopic device in Embodiment 1 includes a movable end The expansion plate 1 and the fixed end expansion plate 2, one end of the movable end expansion plate 1 and one end of the fixed end expansion plate 2 are connected with the balance weight 4 through the horizontal limit column 3, and the other ends are arranged alternately at the fixed end. 4 on;

[0089] The balance weight 4 is fixedly connected with the movable displacement mechanism 5;

[0090] The movable displacement mechanism 5 is fixedly connected with the pre-installed component 6;

[0091] An elastic support 7 is provided at the edge between the balance weight 4 at the fixed end and the pre-installed assembly ...

Embodiment 2

[0114] In the drawings used in Embodiment 2, the same reference numerals as in Embodiment 1 still use the definitions in Embodiment 1.

[0115] Exemplary, such as Figure 13 Shown is the installation front view of a simply-supported bridge expansion device provided by Embodiment 2 of the present application that can rotate in multiple directions. For the sake of simplicity, only the differences between Embodiment 2 and Embodiment 1 will be described below.

[0116] Exemplary, such as Figures 14 to 16 Shown are the front view, left view and front view of the pre-installation assembly 6 at the movable end and the pre-assembly assembly 6 at the fixed end. As shown in the figure, the difference from Embodiment 1 is that the upper end of the vertical plate 602 snaps into the cover plate 601 is inserted into the groove on the bottom surface, and the lower end is inserted into the groove on the top surface of the bottom plate 603 .

[0117] Anchor assembly 604 includes several suc...

Abstract

The invention discloses a simply-supported bridge telescopic device with multi-directional rotation at both ends, which comprises a telescopic plate connected with a balance block by rotation of a horizontal limiting column to realize the horizontal rotation of the telescopic device, and the movable displacement mechanism is fixed to the balance block connection, to prevent overturning caused by the rotation of a single fulcrum, the pre-installed component is fixedly connected to the movable displacement mechanism, the first movable gap is set between the telescopic plate and the pre-installed component, and the edge between the fixed end balance weight and the pre-installed component is provided The elastic support forms a complete support path with the upper structure, realizes the multi-directional displacement of the fixed end, and at the same time avoids the phenomenon of vehicle jumping caused by the fulcrum effect when the vehicle passes by and the additional force of the horizontal limit column. When the end of the expansion plate falls back, It forms a smooth transition surface with adjacent structures to ensure the driving safety of the vehicle; the invention also provides an installation method for simply supported bridge telescopic devices that can rotate in multiple directions at both ends, and the pre-assembly and modular sequential installation methods greatly facilitate On-site construction and installation is conducive to later maintenance and repair.

Description

technical field [0001] The present application relates to the field of bridge structure construction, in particular to a simply supported bridge telescopic device and an installation method with both ends capable of rotating in multiple directions. Background technique [0002] In order to meet the needs of bridge deck deformation, bridge expansion devices must be installed at the bridge joints, and the bridge expansion devices must meet the following basic functions: [0003] ① Bearing function, the bridge telescopic device must be installed at the gap between the beam ends to form a continuous bearing surface to ensure the smooth passage of vehicles. [0004] ②Displacement function, the bridge expansion device must adapt to the expansion and contraction displacement of the beam body caused by temperature changes, shrinkage, creep and load. [0005] ③Anchor function. The bridge expansion device is installed in the later stage of the project and must be reliably anchored wi...
