Adjustable reserved hole constructing mold and constructing method

Abstract

The invention discloses an adjustable reserved hole constructing mold and constructing method. The adjustable reserved hole constructing mold comprises an outer mold, a horizontal bottom plate and an upper covering plate, wherein the horizontal bottom plate is located at the bottom of the inner side of the outer mold, the upper covering plate is installed on the upper part of the outer mold in a covering mode, and the upper covering plate is a round covering plate; the outer mold comprises a vertical cylinder, a horizontal base plate and an annular covering opening; and an eccentric hole is formed in the horizontal bottom plate for passing through of installed pipelines. The adjustable reserved hole constructing method comprises the following steps of step 1, supporting formwork of a cast-in-place slab; step 2, surveying a line of the pipeline installing position; step 3, fixing of the outer mold; step 4, constructing of the cast-in-place slab; step 5, installing of the horizontal bottom plate; step 6, installing of the pipeline; and step 7, sealing and blocking of a hole opening. According to the adjustable reserved hole constructing mold and constructing method, design is reasonable, construction is simple and convenient, and the using effect is good; and the position of through-floorslab pipeline can be adjusted through the horizontal bottom plate with the eccentric holes to guarantee installing precision of the pipeline, and the problems, existing in current reserved hole construction, that working process is complex, potential safety hazards exist in high altitude formwork supporting, and sealing and blocking quality of the hole opening is hard to be guaranteed can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an adjustable construction mold for reserved holes and a construction method. Background technique [0002] With the rapid development of my country's construction industry, structural engineering is becoming more and more complex, and people's requirements for the quality, performance, and appearance of various electromechanical equipment and pipeline installations are also getting higher and higher. The construction of the reserved and pre-embedded stages in construction projects will directly affect the quality of the entire project, so it is particularly important to carry out accurate and scientific reservation and pre-embedded construction. Among them, reservation mainly refers to holes for heating energy and water supply and drainage pipes on walls and panels, and pre-embedding refers to buried pipes and wire boxes. [0003] The development trend...

Problems solved by technology

Nowadays, when carrying out the construction of the hanging hole, the traditional hanging hole construction method is mainly used, the construction efficiency is low and the construction quality is not easy to control; at the same time, there is also a method of using the hanging hole mold to carry out the hanging hole construction, but the actual construction process is complicated , There are potential safety hazards in high-altitude formwork, and the quality of hole sealing is difficult to guarantee, etc.

In addition, there is still a reserved hole construction mold based on UPVC pre-embedded casing. Although this mold has certain beneficial effects, its use range is relatively narrow, and it is limited to the use of UPVC pipes, and the later pipeline installation is more difficult. Large, it is easy to cause problems such as the socket depth of the pipe does not meet the standard requirements and does not meet the operating specifications, and it is difficult to realize the factory processing and standardized construction of the pipe installation
