Water blocking type house expansion joint structure

Abstract

The invention discloses a water blocking type house expansion joint structure. The water blocking type house expansion joint structure comprises a top cover piece, and a containing groove is formed ina roof; the top cover piece comprises an upwards-raised corner plate and two flat pressing plates; an expansion joint is formed between two adjacent house single bodies, the upwards-raised corner plate is located above the expansion joint, and the vertical projection of the expansion joint is located in the range of the vertical protection of the upwards-raised corner plate; the top cover piece further comprises two vertical limiting plates, the flat pressing plates are located between the vertical limiting plates and the upwards-raised corner plate, and the vertical limiting plates are connected with the flat pressing plates; and the lower ends of the vertical limiting plates are located in the containing groove, and transverse expansion gaps are formed between the vertical limiting plates and any groove inner side wall of the containing groove. The water blocking type house expansion joint structure has the beneficial effects that the structure is reasonable, rain sheltering and water proofing protection of the expansion joint between the house single bodies can be achieved effectively, the situation that rainwater enters a house can be avoided, thermal expansion and cold contraction adaptability is high, and the structure is stable; and temporary protection structures such as an elastic sealing plate are arranged, so that the water blocking type house expansion joint structure still has the temporary waterproof effect when an external waterproof structure loses efficacy.

Description

technical field [0001] The invention belongs to the technical field of rainproof structures in substations, and in particular relates to a water-retaining type house expansion joint structure. Background technique [0002] In the substation, some housing buildings are relatively long, which will be composed of multiple continuously arranged housing units, and there will be expansion joints between the housing units (adapting to thermal expansion and contraction), and because there are electrical equipment inside the housing unit, Rainwater must not enter during operation, so there must be a water-retaining structure inside and outside the expansion joints of the house to prevent rainwater from flowing into the house from the expansion joints and affecting the operation of electrical equipment. The current water-retaining structure is mainly water-retaining strips. The traditional water-retaining strip manufacturing process is to first install wooden boards for fixing on both...

AI Technical Summary

Problems solved by technology

In actual use, due to long-term rain erosion, the internal fixing boards rot, causing the water retaining strips to fall off, easily leading to failure of the water retaining structure, and even damage to the electrical equipment in the house
