AI Technical Summary
In traditional construction, the fixing method of reserved holes in cast-in-place structure pipelines is likely to lead to bias, concrete edge loss, unsolidity of back casting gaps and hidden dangers. In addition, manual secondary grooves are required during the decoration and decoration stage, which wastes labor and affects the molding effect.
The embedded structure of electromechanical reserved pipe holes is adopted, including embedded tools and multiple connecting fixing parts. The embedded tool is in a trumpet-like structure and is fixed with the floor bottom mold by self-tapping bolts to form a small and large trumpet-shaped reserved hole. The structure is easy to take out after the concrete is poured, and the post-pouring gap is designed as an inverted trapezoid for compact casting, and is filled with waterproof grooves during the decoration and decoration stage.
During the construction stage, this structure ensures the verticality and molding quality of the reserved holes, avoiding the hidden dangers of concrete edge loss and angle loss and leakage; during the decoration stage, waterproof construction is simplified, the demand for manual grooves is reduced, and construction efficiency and molding effect are improved.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of building electromechanical construction, in particular to a pre-buried structure of an electromechanical reserved pipe hole of a cast-in-place structure pipeline reserved hole. Background Art
[0002] During the main structure construction phase of the building project, when installing and pre-buried rigid pre-buried sleeves that penetrate vertically through the floor slab, the conventional rigid pre-buried sleeves use cylindrical sleeves 20, which are fixed to the floor slab bottom membrane 30 under the cast-in-place floor slab 10 by iron wires, nails, etc. Figure 1 shown.
[0003] The prior art pre-embedding method has the following problems: Figure 2 As shown:
[0004] 1. Traditional pre-embedding uses iron wire, nails and bottom formwork for fixing; this fixing method is prone to disturbance and deviation during concrete pouring;
[0005] 2. After the concrete is poured, the traditional pre-embedded method requires knocking the sleeve and pulling it out after it is separated from the concrete contact surface; the overall sleeve is not easy to remove, and the knocking process can easily cause the concrete to be chipped and cornered, seriously affecting the molding quality of the reserved hole.
[0006] 3. After the formal pipe is installed in the later stage in the traditional reservation method, the post-cast gap 50 between the reserved hole and the formal pipe 40 is small, and the upper and lower widths of the post-cast gap 50 are consistent. It is not easy to pour dense concrete during post-casting, resulting in leakage hazards.
[0007] 4. During the decoration stage, the root of the pipe is a waterproof reinforcement part, which requires manual secondary grooving to meet the waterproof construction requirements. Manual secondary grooving seriously wastes labor and has poor molding effect. The grooving process is prone to cause accidental damage to the pipe.
[0008] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.
