A fast and self-adaptive support device for small-tonnage bridges

Abstract

The invention discloses a fast and self-adaptive support device for small-tonnage bridges, relates to the technical field of bridge reinforcement, and solves the problem that currently used bridge support devices are mainly set up through splicing and assembly, which cannot be quickly supported and assembled. Supporting devices that can be self-expanded in other ways can only be applied to the problem of planar bridge structures. A fast and self-adaptive support device for small-tonnage bridges, including a bottom plate, a pressurizing device and a reinforcement device; both sides of the top of the bottom plate are fixed with bottom cushion seats, and the top of the bottom cushion seat is connected with a middle The pedestal, the top of the middle pedestal is connected with a top pedestal, the top of the top pedestal is connected with a top plate, and the support device can be self-adapted by being provided with a fixed seat and a sliding frame plate. The fixed seat and the sliding frame plate According to the shape of the bottom surface of the bridge, you can choose a vertical or low-angle movable deployment method to facilitate the assembly of the adaptive bridge.

Description

technical field [0001] The invention relates to the technical field of bridge reinforcement, in particular to a fast and self-adaptive support device for small-tonnage bridges. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to cross mountains, poor geology, or meet other traffic needs to make traffic more convenient. The buildings and bridges are generally composed of superstructure, substructure, bearings and auxiliary structures. [0003] After retrieval, for example, the patent No. CN108774957B discloses a support structure for bridge reinforcement, including a base plate, a reinforcement device, and a first support plate and a second support plate that are flexibly connected in an X shape. The left and right sides of the upper end of the base plate are r...

Problems solved by technology

[0007] The purpose of the present invention is to provide a fast and self-adaptive support device for small-tonnage bridges, to solve the problem that the currently used bridge support devices proposed in the above-mentioned background technology are mainly set by splicing and assembling, and cannot support and assemble quickly. Support devices that can be self-expanded by means of fork mechanisms can only be applied to plane bridge structures, and are not suitable for supporting bridges with inclined bottom surfaces.
