Abstract

The invention relates to a prefabricated bridge steel bar positioning device and method. The positioning device comprises a support, a cover body, a clamping block and a fixing device, wherein a groove is formed in the support, the clamping block is arranged in the groove, a steel bar penetrates through the support and the cover body and is clamped by the clamping block, and the fixing device is used for fixing the support and the cover body. According to the technical scheme, a plurality of steel bars can be quickly and conveniently fixed or the fixing can be quickly and conveniently cancelled, and the positioning device is repeatedly assembled, disassembled and used, so that the cost and the working hours are saved.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a prefabricated bridge structure, and in particular to a prefabricated bridge reinforcement lifting positioning device and positioning method. Background technique [0002] With the development of the economy, more and more bridges are being built at the crossings of rivers, mountainous areas, and highways. In the past, bridges were generally constructed by cast-in-place methods. This method has great requirements on the surrounding environment and is easily affected by construction. Conditional restrictions. [0003] In recent years, the fully prefabricated production mode of bridge component factories has been widely used. In the design of fully prefabricated assembled bridges, the prefabricated pier columns are mostly connected on site through the reserved steel bars at the top of the pier columns and the embedded sleeves at the bottom of the prefabricated components of the...
