Problems solved by technology

The conventional construction technology of using PVC pipes or wooden boxes to leave holes, due to the insufficient strength of the mold itself, the holes are prone to deformation, and the reuse rate is low. At the same time, it is difficult to ensure the verticality and forming quality of the reserved holes for pipes , after the hole is formed, it needs to be punched and repaired, which has a great impact on the progress and quality of the project

Embodiment Construction

[0010] Below in conjunction with accompanying drawing and embodiment the technical solution of the present invention is further described:

[0011] like figure 1 As shown, the present invention provides a mold for forming reserved holes for floor sewer pipes, which includes a frustum-shaped metal barrel 2 placed above the floor template 1 and a handle 3 fixed on the upper part of the metal barrel 2. The contact area between the handle 3 and the hand is It can be as large as possible, and the material can be metal strips or ropes. It is mainly for the convenience of drafting. The inner wall of the metal barrel body 2 is welded with a circle of metal ring-shaped ribs 4. The cross-section of the metal ring-shaped ribs 4 is L-shaped. Increase the strength of the metal barrel 2 to avoid deformation during pouring of concrete or daily extrusion and bumping, thereby ensuring the regularity of the holes in the metal barrel 2. The upper opening area of ​​the metal barrel 2 should be la...

Abstract

The invention relates to a building construction tool, in particular to a mould for a floor sewer line reserved hole. The mould comprises a circular truncated cone-shaped metal barrel body arranged above a floor formwork and a handle arranged at the upper part of the metal barrel body, wherein a metal ring-shaped reinforcing rib is arranged on the inner side wall of the metal barrel body; the area of the upper opening of the metal barrel body is greater than that of the bottom of the metal barrel body; a disc-shaped magnet is arranged at the bottom of the metal barrel body; the edge of the magnet is propped against the side wall at the bottom of the metal barrel body; a round metal plate attracted to the magnet is arranged below the floor formwork; a laser radiation lamp is hung in the center of the round metal plate. The mould adopting the technical scheme has high strength and can guarantee the perpendicularity and the quality of the reserved hole.

Description

technical field [0001] The invention relates to a construction tool for construction, in particular to a mold for forming reserved holes for floor sewer pipes. Background technique [0002] In order to facilitate water supply and drainage in different floors of the building, it is necessary to carry out pipeline construction on the building. In order to install the pipeline, it is often necessary to reserve pipeline installation holes during the pouring process of the building. Since the pipeline needs to pass through many different floors, the pipeline The verticality control and forming quality control of reserved holes before installation is a very important process, which directly affects the quality of subsequent pipeline installation and the quality and safety of building structures. The conventional construction technology of using PVC pipes or wooden boxes to leave holes, due to the insufficient strength of the mold itself, the holes are prone to deformation, and th...
