Description

Shielding spool slot for electrical system

Technical Field

The utility model relates to a shielded wire tube groove specifically is a shielded wire tube groove for electrical system, belongs to building application technical field.

Background

The prefabricated concrete technology is a technology for designing and building a concrete structure type house building in a field assembly mode after pouring, curing and forming concrete components in a factory. Compared with the traditional cast-in-place building, the fabricated building has the advantages of high industrialization degree, easy guarantee of construction quality, short construction period, high economic benefit, small influence of climate and the like, and has no problems of water consumption, energy consumption, material waste, much waste discharge and the like caused by field construction. Over the years, fabricated buildings have been heavily supported by national policies because of their unique advantages.

In the existing production process of the precast concrete member, the template is generally dismantled after the casting is finished, so that the labor cost is increased and the material waste is caused. Along with the technical progress, the disassembly-free integrated pouring template can be used for replacing the traditional template, after the template is built and formed, the template is fixed by the connecting rod piece, pouring and maintenance are carried out until the requirement is met, at the moment, the template, the wall body and the connecting rod piece pre-embedded in concrete form a whole, and the template, the wall body and the connecting rod piece are not required to be disassembled, so that the technology of the steel bar template integrated assembled wall body is realized. The technical scheme reduces the construction process, reduces the cost, avoids material waste and meets the national requirements of energy conservation and emission reduction. On the other hand, the disassembly-free integrated pouring template has a large workload when installing concealed and embedded electrical pipelines, electrical boxes and electrical boxes, and the wire pipes, the electrical boxes and the electrical box molds (wood boxes) need to be processed and fixed on the steel bars respectively. This results in a longer period of time for manufacturing and installing the wall.

In addition, when the steel bar formwork integrated assembly type wall is transported to a site for installation, pre-buried electrical pipelines and electrical boxes are easily damaged (flattened, bent, crushed or displaced by steel bars) during installation of the wall, so that strong or weak current lines cannot pass through the line pipes in later electrical threading construction. Even if the installation is finished, when carrying out the concrete and pouring, pre-buried electric pipeline, electric box also receive the damage easily.
