Abstract

The patent is a precast concrete guide wall bracket, and the technical field that it is located is the civil engineering specialty of building industry. The prefabricated guide wall bracket solves the problems that a concrete floor slab is not provided with a supporting point at a guide wall position of a hanging die, an inserted steel bracket is left behind after the bracket is removed, a 2.5cm < 2 > hole is left behind at the junction of a cast-in-situ plate surface and the guide wall, and the like. The prior art has the problems that the holes are poured for the second time, sundries are easy to enter the holes, the holes cannot be cleaned up, the number of the holes is large, and the like, and the effective repair cannot be realized. The water leakage phenomenon and the poor look and feel of the concrete structure floor slab are caused, and in the decoration process, the floor of the decoration wall and the like are seriously polluted, and the normal use functions of users are influenced. The precast concrete guide wall bracket not only solves the quality problem, but also saves labor cost to a great extent, improves work efficiency and reasonably utilizes concrete excess materials. The method effectively ensures the structure quality, improves the construction speed, and is widely applied to all projects of newly opened similar construction processes.

Description

Precast concrete guide wall bracket

Technical Field

This patent is a precast concrete guide wall support. The method is particularly suitable for a tunnel template construction process and a construction process requiring advanced pouring of guide walls, sill and upper counter beams.

Background

In the construction process of introducing Turkey tunnel templates by International engineering company of China railway construction group, aber and Liya company, pouring is completed and meets design requirements in the construction process of a matched plug-in steel guide wall bracket, after the bracket is removed, 2.5m2 holes are left on a cast-in-place floor slab, secondary pouring is needed for the holes, sundries are easy to enter the holes, the holes cannot be cleaned up, the number of the holes is large, and the like, so that effective repair cannot be achieved. The floor slab with the concrete structure is leaked, the appearance is extremely bad, and in the process of decoration and fitment, the floor engineering of the lower wall is seriously polluted, and the normal use function of a user is influenced.

Disclosure of Invention

The prefabricated concrete guide wall bracket is manufactured to replace the original inserted section steel guide wall bracket, so that the structural floor slab is effectively prevented from leaking water, pollution to later-stage decoration and fitment engineering is avoided, and the use function is improved. The concrete bracket is manufactured, and in the use process, labor cost and material cost are saved to a great extent, the construction speed is improved, the working procedures are reduced, and the waste of concrete excess materials is avoided. Can bring good economic effect for projects. The wall body and the plate surface thickness can be controlled by placing the guide wall side templates, and the guide wall side templates are poured in a concrete structure without dismantling, so that the concrete floor achieves the effect of self-waterproofing.

Detailed Description

After the template is assembled, a bilateral bracket concrete guide wall mold is obtained, as shown in fig. 10, after the inner side and the outer side are uniformly coated with release agents, the residual concrete is poured by using a structure pouring, the receiving surface is vibrated, the receiving surface is covered by a plastic film, and curing is carried out before final curing (normal 8 hours to 12 hours). After pouring is completed for 24 hours, the die is disassembled, and a precast concrete guide wall bracket is obtained as shown in fig. 11; placing the precast concrete guide wall bracket into a standard curing room for curing, placing different specifications and sizes in batches for standard curing for 28 days, and transporting to a construction site to be installed together with the guide wall template when the curing test block under the same conditions meets the design strength requirement as shown in fig. 12; after pouring is completed, after the strength of the same-condition maintenance test block meets the design requirement, removing the mold, forming a concrete structure ceiling picture as shown in fig. 13, and meeting the requirements of bare concrete; each layer of structure plate surface adopts a limit picking mode, thereby avoiding erroneous picking and waste. And after pouring, carrying out water storage acceptance inspection on the prefabricated concrete guide wall bracket. The concrete structure floor slab is guaranteed to have a self-waterproof function.
