[0138] (1) Project overview

[0139] (2) Application

[0140] Among the 11 bridges in this project, the Yongning River Bridge is a new bridge, which uses pre-tensioned prestressed concrete hollow slabs, 5 spans, and a span of 20m. The original design used traditional PTFE plate rubber for 0# and 5# Bearings, considering the shortcomings of traditional bridge PTFE plate-type rubber bearings, such as large installation position deviation and prone to safety accidents, with the consent of Party A, design and supervision units, the 0# and 5# bridges of this bridge were erected In the construction of the project, the corrugated PTFE plate rubber bearing of this construction method was adopted.

[0142] (1) Project overview

[0143] (2) Application

[0144] Among the two bridges in this project, the No. 6 River bridge project has a total length of 21.04m, a single hole, and a span of 16m. The upper structure of the bridge adopts 1×16m simply supported prestressed concrete hollow slab girder, and the lower part adopts light abutment and bored pile foundation. The pile foundation is connected to the abutment cover beam. In the original design, 32 traditional PTFE rubber bearings were used in the 1# abutment. After discussion, with the consent of Party A, the design and supervision unit, the corrugated PTFE rubber bearings were used instead.

Abstract

The invention discloses an installing method of a wave surface tetrafluorohydrazine plate rubber support one-way constraint prefabricated beam plate. Certain constraint force is exerted on a prefabricated beam in the installing process, and the disadvantages that due to omnibearing movement of the prefabricated beam, the installing position is uneasy to control and a slip accident easily occurs are avoided; the use of tetrafluorohydrazine plate rubber support silicone grease oil is guaranteed, longitudinal slide failure of the support is avoided, and the service life of the support is prolonged; in the later using process of a bridge, elastic constraint force is exerted on the prefabricated beam, part of impact force of a vehicle and seismic force can be buffered, and anti-impact and seismic performance of the bridge is improved. By means of the installing method of the wave surface tetrafluorohydrazine plate rubber support one-way constraint prefabricated beam plate, the installing efficiency and position accuracy of the prefabricated beam are improved, the service life of the support and the beam plate is prolonged, materials are saved, environmental pollution is reduced, the time in the installing process is greatly shortened, repeated use of a machine is reduced, and the installing method is significant in safety of the installing, constructing and operating stage of the prefabricated beam.

Description

technical field [0001] The invention relates to a method for installing a prefabricated beam plate with one-way restraint of a rubber bearing of a corrugated PTFE plate. Background technique [0002] The prefabricated beam-slab unidirectional restraint installation is a bridge erection method based on a new wave-surface PTFE plate rubber bearing. The wave-surface unidirectional PTFE plate support is composed of a corrugated stainless steel plate 1 and a wave-surface PTFE plate rubber figure 1 ), the corrugated stainless steel plate and the corrugated PTFE plate rubber support form a one-way sliding surface, and the gravity component of the prefabricated beam slab formed transversely through the wave surface of the support in the process of erecting the prefabricated beam slab transversely constrains the beam slab laterally. The position of the beam is controlled by the position of the trough of the support, which makes it easier to control the position of the falling beam du...
