Sealing waterproof device of building

Abstract

The invention relates to the technical field of sealing and waterproofing, in particular to a sealing and waterproofing device for a building. The device comprises a pair of telescopic devices, cylinders are arranged in the telescopic devices, rubber sleeves are arranged on the outer sides of the cylinders, baffles are symmetrically and fixedly installed on the inner walls of the cylinders, first guide rollers are rotatably installed between the two baffles, a pair of openings are formed in the outer sides of the cylinders, and the two first guide rollers are connected through a rubber belt. Rotary switching of the shielding rubber belt used for shielding the water stop belt can be achieved, so that the face, making contact with sunlight, of the rubber belt can be continuously switched, the situation that one position of the rubber belt makes contact with the sunlight for a long time can be avoided, and then the service life of the rubber belt is prolonged; and impurities falling on the surface of the rubber belt can be cleaned while the rubber belt is switched, so that the situation of impurity accumulation can be avoided, the situation that use of the telescopic device is affected due to excessive impurity accumulation is avoided, and the telescopic device is worthy of popularization and use.

Description

technical field [0001] The invention relates to the technical field of sealing and waterproofing, in particular to a sealing and waterproofing device for buildings. Background technique [0002] Bridges belong to a class of buildings. Expansion joints will be reserved during the construction of bridges, which means to prevent the building components from cracking or damaging the structure due to climate temperature changes (thermal expansion, cold contraction). A structural joint is set at an appropriate position in the direction of the construction joint of a structure, and an expansion joint device will be set at the expansion joint. [0003] In order to waterproof the pier column below the expansion joint, a sealing waterproof device is usually installed at the expansion joint device. The existing waterproof waterproof device is composed of a water stop belt and a rubber belt arranged above it to protect the water stop belt. The rainwater is shielded by the waterstop, an...

Problems solved by technology

[0003] In order to waterproof and seal the abutment column below the expansion joint, a sealing and waterproof device is usually installed at the expansion joint device. The existing sealing and waterproof device is composed of a waterstop and a rubber belt arranged above it to protect the waterstop. The rainwater is blocked by the waterstop to realize the sealing and waterproofing of the pier and abutment columns below. The rubber belt can be used to shade the waterstop and block impurities, so as to realize the protection of the waterstop and prolong its service life. However, the existing When the sealing and waterproof device is in use, the rubber belt is fixed, so that one part of the rubber belt will continue to be exposed to the sun, which is easy to age, and the impurities accumulated on the surface of the rubber belt cannot be cleaned, which will cause the accumulation of impurities to block the telescopic device and affect its performance. The use of the situation arises
