Aluminum alloy formwork top plate water supply and drainage reserved hole mold and construction method thereof

Abstract

The invention provides an aluminum alloy formwork top plate water supply and drainage reserved hole mold and a construction method thereof. The construction method comprises the following steps that S1, a reserved hole center point is positioned; S2, an embedded pipe and a square pipe tangent to the inner wall of the embedded pipe are manufactured; S3, the square tube is positioned and fixed; S4,a hole is formed in the center line of the square tube; S5, a nut is welded to the position, corresponding to the open hole, of the upper portion of the square pipe, an tie rod is screwed into the nutin a threaded connection mode; S6, the embedded pipe is positioned and placed to enable the inner wall of the embedded pipe to be tangent to the square pipe; S7, a baffle plate is arranged at the opening end of the embedded pipe, a through hole penetrating through the tie rod is formed in the baffle plate; S8, the baffle plate is fixed to the tie rod through the nut, correction is carried out while fixing is carried out; S9, concrete is poured, the tie rod is corrected in real time; and S10, after the concrete reaches the required strength, the formwork is removed, and the embedded pipe is recycled. The aluminum alloy formwork top plate water supply and drainage reserved hole mold and the construction method thereof are simple, practical, capable of effectively improving the constructionaccuracy of the water supply and drainage preburied hole and improving the engineering quality, good in using effect and capable of being used and popularized.

Description

technical field [0001] The invention relates to a construction technology for reserved holes for water supply and drainage, in particular to a die for reserved holes for water supply and drainage on an aluminum alloy formwork roof and a construction method thereof. Background technique [0002] With the development of my country's reform and opening up and the improvement of domestic living standards, people's requirements for living conditions are getting higher and higher, and residential land is getting less and less. many. For civil construction projects, the development brought about by the rapid expansion of its scale is becoming a thing of the past, and construction companies in the traditional construction industry are facing fierce market competition. Construction quality is an important indicator for assessing a construction enterprise. The importance of quality has been highlighted, and aluminum alloy formwork is favored by construction enterprises for its many ad...

AI Technical Summary

Problems solved by technology

[0003] The following problems will be encountered when the aluminum alloy formwork is used for the construction of reserved holes for water supply and drainage: 1. The construction period is affected due to the slow installation of the reserved casing

2. The reserved bushing is installed incorrectly or shifted after installation, which will affect the later installation

3. It is difficult to fix the position of the water supply and drainage hole by the aluminum mold, and it cannot be reused

4. The traditional construction method will damage the aluminum mold, the hole is not easy to seal, and the grout will leak during concrete pouring, which will affect the concrete forming in the later stage, and the traditional method of reserving holes for fixed water supply and drainage pipes on the wooden formwork cannot be applied to the aluminum mold

The construction method of the log formwork is to use multi-strand wires and iron nails to fix the reserved iron pipes on the wooden formwork. The iron nails cannot be easily nailed into the aluminum alloy formwork, and it is difficult to remove the formwork separately after fixing.

5. If the casing is directly embedded, due to the large number of floors, the aluminum mold changes on some floors, the embedded position is not accurate, and the vertical accuracy requirements are higher when the water supply and drainage pipes are installed in the later stage, so the control is more difficult. The cost of later rework is high and the rework is difficult

6. During the concrete pouring process, the concrete is easy to enter the reserved hole for pre-embedding, which will affect the later installation
