AI Technical Summary

Technical Problem

The dry moisture-proof layer of the existing building exterior wall is an integrated structure. Once moisture is absorbed in a certain place, it will cause large-scale infiltration. The water-absorbing place cannot be replaced, causing the wall to become moldy and corroded.

Method used

It adopts a fireproof board frame structure, including a moisture-proof frame, a waterproof layer and a protective plate. Through the design of staggered air holes and waterproof strips, combined with a moisture-proof membrane and a fire-proof mortar layer, a multi-layer protection is formed. The lime board can be replaced separately, and the thermal insulation single board forms a whole under the partition of the fire-proof mortar layer. The protective plate is wavy to accelerate evaporation.

Benefits of technology

It improves the waterproof, moisture-proof and fire-proof performance of the exterior wall, prevents water vapor penetration, reduces the possibility of moisture, prevents the insulation board from cracking, and improves the overall structural strength and fire-proof performance.

Abstract

The utility model relates to the technical field of building outer walls, and discloses a waterproof and moistureproof building outer wall protection structure which comprises a fireproof plate frame, a moistureproof frame is fixedly arranged on the front side of the fireproof plate frame, a moistureproof assembly is arranged in the moistureproof frame, a waterproof layer is fixedly arranged on the front side of the moistureproof frame, and a protection plate is fixedly arranged on the front side of the waterproof layer. By means of the design of the wavy end faces of the protection plates, the flow speed of wind on the surfaces of the protection plates can be increased, evaporation of rainwater is accelerated, the waterproof effect is improved in cooperation with the waterproof layer, meanwhile, the lime plates are used for absorbing moisture entering the interior through the front-back staggered air holes of the moisture-proof frame, and the moisture-proof effect is improved. Partition is formed among the lime plates through the waterproof strips, the possibility that the outer wall is affected with damp is reduced, and the waterproof and moisture-proof performance of the outer wall is effectively improved.
