Embodiment Construction

[0025] figure 1 and figure 2 It is respectively the schematic diagram of the end of the expansion device of the bridge under two different situations of double-slope cover plates (2) being placed on the top and placed below. In practical application, when the double-slope cover plate (2) is placed on top, the setting of the waterstop (3) refers to the comb-tooth bridge telescopic device, and this figure only shows the approximate position of the waterstop. When the double-slope cover is lowered, the telescopic panel is tilted to achieve the purpose of water resistance and waterproofing. In this manual, for the convenience of understanding, the non-warped head is taken as an example for illustration.

[0026] figure 1 The situation where the double-slope cover plate of the present invention is placed on top is shown. This setting method is suitable for motor vehicle lanes, where a large number of heavy-duty vehicles pass, and has the advantage of a simple structure and a l...

Abstract

A double-slope bridge telescopic device, the vehicle load is transmitted to the beam body through the cooperation between the slopes on both sides of the bottom of the double-slope cover plate and the slope at the top angle of the beam end. During the displacement process, the top surface of the bridge telescopic device is basically flush with the bridge deck, and is waterproofed through the water stop belt or the telescopic panel. The telescopic panel is formed by solidifying rubber strips and pearl cotton strips along the bridge direction. The bridgewise width of adjacent pearl cotton strips is less than two-thirds of the bridgewise width of the rubber strips. When the expansion panel is used in the double-slope bridge expansion device, the two sides of the bottom surface of the expansion panel are respectively sealed and fixed with the top surfaces of the beams on both sides of the expansion joint, and the middle part of the expansion panel is sealed and fixed with the cover plate along the length direction of the double-slope cover plate. It is a bridge telescopic device with simple structure, low cost, shallow burial without burial, good waterproof performance, easy expansion and contraction, easy installation, easy maintenance, and comfortable driving.

Description

technical field [0001] The invention relates to a bridge expansion device, which is especially suitable for expansion joints with an expansion range of 80 mm to 400 mm. Background technique [0002] For expansion joints with an expansion range of 80mm to 400mm, there are basically three types to choose from: modular type, comb type and rubber type bridge expansion device. The modular reserved groove requires a deep depth, and the position of the displacement control box must be reserved, which does not conform to the design trend of shallow burial, and its structure is complex. The problem of comb teeth lifting and broken teeth is frequent. At the same time, due to the unreasonable design of the modulus type and the comb type, the anchoring system is frequently damaged, and the manufacturing cost remains high. The rubber-type bridge expansion device has high expansion and contraction friction, difficult installation, poor waterproof performance, fragile anchors, and diffic...
