Assembled concrete wall waterproof structure

Abstract

The invention relates to assembled building water prevention, in particular to an assembled concrete wall waterproof structure. A plurality of prefabricated plates spliced into a wall are included. Waterproof layers are arranged at the positions of transverse joints and vertical joints of the prefabricated plates. Each waterproof layer sequentially comprises a seal glue isolation layer and a sealglue layer from the interior of the corresponding joint to the exterior of the corresponding joint, wherein the seal glue isolation layer is composed of at least one flexible strip, the flexible stripis extruded by the inner wall of the corresponding joint and embedded in the corresponding joint and extends along the corresponding joint. The transverse joints are each of a reverse bridge structure. A waterproof layer is arranged between the first top end and the first bottom end. Cavities are reserved behind the seal glue isolation layers in the vertical joints, and a vertical water discharging channel is formed by the cavities. A gap gradually narrowed from exterior to interior is formed between the first bottom end and the first top end, wherein the first bottom end is obliquely arranged. According to the waterproof structure, later frequent maintenance is omitted, a large number of maintenance materials are saved, construction waste generation is reduced, and the requirements of existing assembled buildings for economy, environment protection and energy saving are well met.

Description

technical field [0001] The patent of the invention relates to the waterproofing of prefabricated buildings, in particular to a waterproof structure of prefabricated concrete walls. Background technique [0002] Prefabricated buildings can save a lot of resources, be economical and environmentally friendly, and meet the characteristics of green buildings. They have also been paid more and more attention, and a relatively mature construction system for the main structure of prefabricated concrete buildings has gradually formed. However, to achieve the functional integrity of prefabricated concrete buildings, there is another important part - the waterproofing of the exterior walls of prefabricated concrete buildings. [0003] At present, in the main structure of prefabricated concrete buildings, the peripheral retaining wall usually adopts connection methods such as cast-in-place node connection and sleeve grouting connection, in which the prefabricated slab and the cast-in-pl...

AI Technical Summary

Problems solved by technology

[0003] At present, in the main structure of prefabricated concrete buildings, the peripheral retaining wall usually adopts connection methods such as cast-in-place node connection and sleeve grouting connection, in which the prefabricated slab and the cast-in-place node are horizontally continuous to form vertical joints, and the prefabricated slab is connected through sleeve grouting Form horizontal seams, such a large number of seams make it difficult to guarantee the waterproofing of building exterior walls

At the same time, the non-repairability of composite thermal insulation exterior wall panels also greatly increases the difficulty of leakage control of the exterior walls of prefabricated concrete buildings, which cannot meet the current economic, energy-saving and environmental requirements.
