Abstract

The patent is a precast concrete wall guide bracket, and the technical field of the precast concrete wall guide bracket is the construction industry and civil engineering major. The prefabricated guide wall support solves the problems that a concrete floor slab does not have a supporting point at a guide wall hanging mould, an inserted steel support is left after being dismantled after the support is dismantled, and a hole of 2.5cm2 is left at the junction of a cast-in-place plate surface and the guide wall. The original process has the problems that the holes are poured for the second time, impurities are easy to enter the holes, the holes cannot be cleaned up, the number of the holes is large, and the like, and the holes cannot be repaired effectively. The water leakage phenomenon of the concrete structure floor is caused, the appearance is very poor, in the decoration process, the decoration wall, the ground and the like are seriously polluted, and the normal use function of a user is influenced. The precast concrete guide wall bracket not only solves the quality problems, but also saves labor cost to a great extent, improves work efficiency and reasonably utilizes concrete excess materials. The method effectively ensures the structural quality, improves the construction speed and is widely applied to all projects of newly-developed similar construction processes.

Description

Precast concrete wall guide support
Technical Field
The patent relates to a precast concrete guide wall bracket, which is particularly suitable for a tunnel formwork construction process and a construction process needing to pour a guide wall, a ridge platform and an upper reversed beam in advance.
Background
The tunnel formwork construction process of Turkish introduced by International engineering company of middle iron construction group, Allan and Liya division is completed in the construction process of a matched inserted steel guide wall bracket, pouring is completed and the design requirements are met, after the bracket is disassembled, a 2.5cm2 hole is left in a cast-in-place floor slab, the hole needs secondary pouring, impurities easily enter the hole, the hole cannot be cleaned completely, the number of the holes is large, and the like, so that effective repairing cannot be achieved. Causes water leakage of the concrete structure floor, has poor appearance, causes serious pollution to the ground engineering of the lower floor wall in the process of decoration and fitment and influences the normal use function of users.
Disclosure of Invention
The precast concrete wall guide support replaces the original inserted section steel wall guide support, effectively prevents that the structural floor from leaking, avoids later stage decoration and finishing engineering to receive the pollution, improves the service function. The concrete support is manufactured as shown in the attached drawing 11, labor cost and material cost are saved to a great extent, construction speed is improved, working procedures are reduced, and waste of concrete excess materials is avoided. Can bring good economic effect for the project.
Drawings
The patent is further explained with reference to the drawings and the implementation effect.
FIG. 1 is a grid plate of a single-sided bracket guide wall mold, FIG. 2 is a grid plate of a double-sided bracket guide wall mold, FIG. 3 is a plastic sleeve between grids, FIG. 4 is a guide wall mold bottom mold, FIG. 5 is a guide wall mold side wall plate, FIG. 6 is a mold grid, a screw, a plastic sleeve, a bottom plate combination, FIG. 7 is a single-sided bracket guide wall mold assembly drawing, FIG. 8 is a double-sided bracket guide wall mold assembly drawing, FIG. 9 is a single-sided bracket guide wall mold assembly drawing, FIG. 10 is a double-sided bracket guide wall mold assembly drawing, FIG. 11 is a double-sided bracket precast concrete guide wall bracket, FIG. 12 is a precast concrete guide wall bracket installation solid picture, FIG. 13 is a precast concrete guide wall bracket installation solid picture after the mold is disassembled
Detailed Description
And (3) after the assembly of the figures 2 to 6 is completed, obtaining the double-side support concrete guide wall mould, as shown in figure 10, after the inside and the outside are uniformly coated with the release agent, pouring the rest concrete by using the structure, vibrating the surface, covering the surface with a plastic film, and curing before final setting (normally 8 to 12 hours). After the pouring is finished for 24 hours, the mould is removed, and the 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, numbering in batches with different specifications and sizes, performing standard curing for 28 days, and transporting to a construction site to be installed together with a guide wall template after the same-condition curing test block meets the design strength requirement as shown in figure 12; after the pouring is finished, after the strength of the maintenance test block meets the design requirement and the formwork is removed under the same condition, the picture of the concrete structure ceiling is shown in figure 13, and the requirement of the fair-faced concrete can be met; and the board surface of each layer of structure adopts a quota getting mode, so that the mistaking and the waste are avoided. And after the pouring is finished, carrying out water storage acceptance inspection on the support part of the precast concrete guide wall. The concrete structure floor is guaranteed to have the self-waterproof function.
