Stable supporting device for bridge

Abstract

The invention discloses a stable supporting device for a bridge. The stable supporting device comprises a supporting transverse plate. A supporting block is fixedly connected to the middle of the supporting transverse plate. Side supporting plates are symmetrically installed on the two sides of the supporting block. One end of each side supporting plate is rotationally connected with the supporting transverse plate through a pin shaft. Four hydraulic brackets are uniformly installed on the upper end surface of the supporting transverse plate. The upper end surfaces of the hydraulic brackets are connected with the lower end surfaces of the side supporting plates. The lower end surface of the supporting transverse plate is connected with a damping supporting body through a supporting platform. A bottom plate is fixedly connected with the lower end surface of the damping supporting body. Rubber pads are arranged on the upper end surfaces of the side supporting plates and the upper end surface of the supporting block. Pressure sensors are embedded in the upper end surfaces of the rubber pads. According to the stable supporting device for the bridge, the drawbacks that a traditional supporting frame cannot be used repeatedly and is inconvenient to assemble and disassemble are overcome; the stable supporting device can be adjusted according to the bottom surface slope of the bridge, so that the supporting force is more uniform, and certain damping capacity is achieved; and the supporting intensity can be measured in real time so as to improve the safety coefficient.

Description

technical field [0001] The invention relates to the technical field of bridge support, in particular to a bridge stability support device. Background technique [0002] With the continuous development of social economy and the continuous improvement of construction level, as well as the continuous increase of vehicles, large and small bridges have been built; in bridge construction and maintenance operations, support brackets are often used; traditional support frames are more It is made of steel pipes, such as scaffolding commonly used in construction. Due to the large number of pipe fittings in the scaffolding, it is difficult to build, the construction progress is slow, and a lot of manpower is required to complete the construction, which brings great difficulties to bridge construction and maintenance. This caused great trouble; although at present in the construction of bridges, large steel plates have been pre-embedded in the bridge piers, and after the triangular brac...

Problems solved by technology

[0002] With the continuous development of social economy and the continuous improvement of construction level, as well as the continuous increase of vehicles, large and small bridges have been built; in bridge construction and maintenance operations, support brackets are often used; traditional support frames are more It is made of steel pipes, such as the scaffolding commonly used in construction. Due to the large number of pipe fittings in the scaffolding, it is difficult to build, the construction progress is slow, and a lot of manpower is required to complete the construction, which brings great difficulties to the construction and maintenance of bridges. This caused great trouble; although at present in the construction of bridges, large steel plates have been pre-embedded in the bridge piers, and after the triangular bracket is assembled and welded under the bridge, the single-piece hoisting is in place and welded with the pre-embedded steel plates; although this method It can overcome the shortcomings of scaffolding such as difficulty in construction, slow construction progress, and the need for a lot of manpower to complete the construction. However, during the welding process of the triangular bracket, there are the following problems: high-altitude vertical welding, difficult to guarantee the quality of the weld, and potential safety hazards; The welding seam is long, the workload of high-altitude welding is heavy, and the installation period of the bracket is long; the bracket needs to be cut off from the embedded steel plate by gas welding when dismantling, which is difficult to remove, and the triangular bracket after gas welding is seriously damaged, so it is not suitable for repeated use , the turnover is poor, and the bracket investment is large; after the bracket is removed, it is difficult to handle the pre-embedded large steel plate, which affects the appearance quality of the bridge pier; the traditional support frame is poor in stability and cannot be adjusted according to the slope of the bridge bottom, and cannot be measured from time to time Support strength, there are safety hazards
