A prefabricated concrete box girder comb plate fixing device

Abstract

The invention discloses a fixing device for fixing a comb plate to a precast concrete box beam. The fixing device disclosed by the invention comprises a comb plate body, a limiting device, a fixing device, a box beam surface layer reinforcing bar and a box beam mold plate, wherein the comb plate body consists of a comb plate surface plate and reinforcing plates; the comb plate surface plate comprises a horizontal plate and a vertical plate which are welded in an L shape; the bottom edge of each reinforcing plate is fixed to the horizontal plate, and a side edge of each reinforcing plate is fixed to the vertical plate; a plurality of U-shaped grooves are formed in the vertical plate; fixing platforms are fixedly arranged on the horizontal plate; after the box beam surface layer reinforcing bar penetrates through the U-shaped grooves for banding, a pressing strip penetrates through fixing holes to be arranged on the upper surface of the comb plate body in a pressing manner, and is in bolt fixation through the fixing hole formed in each fixing platform and the corresponding through holes formed in the pressing strip; a fixing device is arranged on the limiting device; and one end of the fixing device is arranged on the other side edge of each reinforcing plate in a clamping manner to fix the comb plate body, and the other end of the fixing device is fixed on the box beam mold plate through the limiting device. Through the adoption of the fixing device disclosed by the invention, the comb plate is horizontally and vertically fixed, and the fixing stability and the fixing reliability of the comb plate are strengthened.

Description

technical field [0001] The patent of the invention belongs to the field of concrete prefabricated component production, and specifically relates to a prefabricated concrete box girder comb plate fixing device. Background technique [0002] With the advancement of construction industrialization, municipal components have been vigorously developed, and various production processes have also been updated in the production process. [0003] At present, most of the precast concrete box girders have the problem of inner mold floating in the production process. With the inner mold rising, a series of production problems will occur. If the surface layer of steel bars floats up, it will lead to the separation between the comb plate and the box girder formwork. , so that concrete leaks between the gaps, resulting in quality problems and waste of materials. [0004] In the original production process, the comb plate is positioned. The first method is to weld the comb plates to the pr...

Problems solved by technology

However, when removing the comb plate, sometimes the comb plate will be deformed because the welding point is too strong, and the welding point will also vibrate when the concrete is poured, resulting in concrete leakage
