Description

A kind of PVC pipe material for perforation of building wall that is easy to wrap pearl cotton

technical field

The utility model relates to the technical field of building construction, in particular to a PVC pipe material for perforating a building wall that is easy to wrap pearl cotton.

Background technique

With the continuous development of society, the construction industry has developed vigorously. The embedded casing is the hole reserved for the pipe to pass through the wall, concrete beam, concrete wall, etc. during the construction process. It is suitable for civil air defense, underground engineering, Chemical industry, iron and steel, tap water, sewage treatment and other pipelines require strict waterproofing through walls. In order to facilitate the recycling of embedded casings, a PVC pipe for perforation of building walls that is easy to wrap pearl cotton will be used.

For this reason, the patent with the publication number CN210459973U relates to the technical field of construction equipment, and is specifically a kind of convenient embedded pipe, including the embedded pipe body, the outer ring of the embedded pipe body is covered with a plastic film layer, and the embedded The buried pipe body is pre-buried inside the pouring wall of the building, and a limiting ring is arranged at the outer ring of the left end of the pre-buried pipe body. Beneficial effects: In the utility model, a plastic film layer is set on the outer layer of the pre-embedded pipe body, and when a reserved hole is left for the building pouring wall, the pre-embedded pipe body can be taken out after the poured concrete is air-dried, which is convenient for recycling , which reduces the cost of building construction; the left end of the pre-embedded pipe body in the utility model is connected to the limit ring through the connecting ring, and the limit ring is attached to the left side of the building pouring wall, which realizes the purpose of limit, and the pre-embedded pipe body is in the It is not easy to move and fall out when the building is poured into the wall. After air drying, the pre-embedded pipe body can be taken out by pulling the pull ring on the limit ring, which is convenient and practical. The overall structure is simple, the production cost is low, and the use cost is reduced.

The above-mentioned pre-embedded pipe The pre-embedded pipe is coated with a plastic film layer on the outer ring, so that the pre-embedded pipe can be easily taken out from the building wall in the later stage. However, the plastic film layer has poor toughness. When pouring concrete, the concrete will cause damage to the plastic film layer. Scratches cause the plastic film layer to lose its isolation effect, and the plastic film layer is not easy to fix on the outside of the embedded pipe, causing the plastic film layer to fall off easily, which is time-consuming and labor-intensive during use, making its applicability low during use.
