A plugging device for reserved openings of water supply and drainage sleeve pipes on structural roofs for urban construction projects

Abstract

The invention provides a plugging device for the reserved opening of the water supply and drainage casing on the structural roof used in urban construction projects, relates to the technical field of sealing devices, and solves the problem of the existing plugging device for the reserved hole of the water supply and drainage casing, which is usually used during construction. It is troublesome to install the sleeve socket at the time, which is not conducive to the disassembly of the plugging device and the laying of the water pipe in the later stage, and the connection between the water supply and drainage pipe and the plugging nozzle is relatively poor in airtightness, and it is easy to be corroded during long-term use, and internal water seepage occurs The problem of the situation includes the plugging sleeve, the plugging sleeve is a cylindrical through-cavity structure, and the top of the plugging sleeve is welded with a closed nozzle. In the present invention, since the bottom end of the fixed ring is provided with four slots, when the fixed ring and the connecting ring are in a connected state, the inserting plate is slid into the slot and locked by the fixing bolt, and by installing the fixing ring and the connecting ring, The plugging casing and the water supply and drainage casing are firmly connected, effectively preventing the plugging casing and the water supply and drainage casing from loosening, and ensuring the stability of the structure.

Description

technical field [0001] The invention belongs to the technical field of plugging devices, and more specifically relates to a plugging device for openings reserved for water supply and drainage sleeve pipes on structural roofs for urban construction projects. Background technique [0002] With the development of the construction industry, there is a trend of stereotyped and industrialized tools in the construction process. In the construction stage of the main body of the building, in order to install the indoor water supply and drainage pipes later, the water supply and drainage pipes must be pre-embedded before concrete pouring. The reservation and pre-embedding of pipelines are particularly important. The positions of reserved holes and pre-embedded casings must be accurate, and no leaks or burials are allowed. [0003] For example, the invention of application number: CN201910630541.5 belongs to the field of building construction, and specifically relates to a plugging de...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a plugging device for openings reserved for water supply and drainage casings on structural roofs for urban construction projects, to solve the problem that the connection structure of the existing plugging devices for reserved holes for water supply and drainage casings is not easy. Operation, usually the installation of socket joints during construction is cumbersome, which is not conducive to the disassembly of the plugging device and the laying of water pipes in the later stage, and the connection between the water supply and drainage pipes and the plugging nozzle is relatively poor in airtightness, and it is easy to be damaged during long-term use. Corrosion, leading to loose joints and internal water seepage
