Construction method of pipe gallery and formwork assembly for pipe gallery construction

Abstract

The invention discloses a pipe rack construction method. A template assembly provided with a bottom plate and a template assembly for pouring of a pipe rack wall and a top plate are included. The template assembly provided with the bottom plate comprises bottom plate inner side templates and bottom plate outer side templates, and the bottom ends of the bottom plate inner side templates are higher than the bottom ends of the bottom plate outer side templates, and a pipe rack bottom plate is poured to the position near the bottom ends of the bottom plate inner side templates from the part between the bottom plate inner side templates. The bottom plate side wall is poured to the position near the top ends of the bottom plate inner side templates and the top ends of the bottom plate outer side templates from the part between the bottom plate inner side templates and the bottom plate outer side templates. The pipe rack wall is poured from the position above wall side wall templates. A top plate is poured from the position above a top plate template. A template assembly for pipe rack construction comprises a bottom plate template assembly and a wall and top plate template assembly. The bottom ends of bottom plate inner side templates are higher than the bottom ends of bottom plate outer side templates. The wall and top plate template assembly comprises wall side wall templates connected with the upper ends of the bottom plate inner side templates or the upper ends of the bottom plate outer side templates, and the top plate template connected with the upper ends of the wall side wall templates.

Description

technical field [0001] The invention relates to the field of pipe gallery construction, in particular to a construction method for a pipe gallery; the invention also relates to a formwork set for the construction of a pipe gallery. Background technique [0002] During the construction of the pipe gallery, wooden formwork or aluminum alloy planks are usually used for construction. Wood formwork is used for construction, and the molding effect is poor. Aluminum alloy formwork is used for construction. Because most of them are tie rod systems, on the one hand, the cost of waterproof tie rods is high, and on the other hand, cement is easy to enter the tie rod sleeves, making it impossible to take out the tie rods. In addition, the back corrugation of the tie rod system is heavy, and the labor intensity of the workers is high during the construction of the super high-rise corridor; in addition, the lower end of the side wall formwork of the pipe gallery is generally fixed to the...

Using wooden formwork for construction, the molding effect is poor

Aluminum alloy formwork is used for construction. Because most of them are tie rod systems, on the one hand, the cost of waterproof tie rods is high;

In addition, the back corrugation of the tie rod system is heavy, and the labor intensity of the workers is high during the construction of the super high-rise corridor; in addition, the lower end of the side wall formwork of the pipe gallery is generally fixed to the bottom plate by diagonal supports, and the upper end is connected to the top plate by a splayed formwork , the oblique support installation is troublesome, and the eight-character corner formwork is generally completed by welding, the process is complicated, and the strength is insufficient

The span of the pipe gallery is relatively large, and the existing construction methods and formwork cannot guarantee the strength
