Embodiment Construction

[0046] see figure 1 and figure 2 , the pier column in this embodiment is a prefabricated pier column 2, and the top of the prefabricated pier column 2 has a protruding pier column embedded steel bar 15, and the pier column pre-embedded steel bar 15 is evenly distributed in a circular shape on the top of the prefabricated pier column 2, Form a pier column pre-embedded steel bar ring with a radius of r; the cover beam is a prefabricated cover beam 22, and the two ends of the prefabricated cover beam 22 are pre-embedded with a cover beam pre-embedded sleeve 19, and the cover beam pre-embedded sleeve 19 can use steel corrugation The corrugated pipe structure can further enhance the bonding firmness between the pre-embedded steel bar 15 of the pier column and the pre-embedded sleeve 19 of the cover beam. On the top of the prefabricated cover beam 22, there is a vertical grouting channel 17 and the steel bar connection sleeve. 19 are connected; the prefabricated cover beam pre-emb...

Abstract

The invention discloses a capping beam mounting method for mutual constraint of adjacent pier columns in a prefabricated bridge. The capping beam mounting method comprises steps of arranging a cappingbeam formwork according to a capping beam form, respectively and fixedly arranging limiting steel rings at two ends of a rectangular frame, and vertically arranging steel bar sleeves in the limitingsteel rings; in the installation process, hoisting a bent cap formwork at the tops of every two adjacent prefabricated pier columns, and inserting pier column embedded steel bars protruding out of tops of the two prefabricated pier columns into the steel bar sleeves at two ends of the bent cap formwork in a one-to-one correspondence mode; limiting the two adjacent prefabricated pier columns in thebent cap formwork; The method is advantaged in that construction efficiency of bent cap installation can be remarkably improved, and the engineering quality is guaranteed.

Description

technical field [0001] The invention relates to the construction field of prefabricated and assembled bridges, and more specifically aims at the installation and construction method of pier columns and cover beams of prefabricated and assembled bridges in highway bridge engineering. Background technique [0002] Fully-fabricated bridges are becoming the development trend of bridge construction today. By factory prefabricating components such as pier columns and cap beams, and realizing prefabricated construction on site, the level of mechanized operation can be significantly improved, and the construction progress can be accelerated while improving quality. At the same time, the improvement of construction efficiency of fully prefabricated bridges can greatly reduce the interference to existing traffic, which is conducive to environmental protection. [0003] For the installation and construction of prefabricated assembled pier columns and cover beams in highway bridge engin...
