Slab joint rubber strip waterproof device of assembled building precast concrete slab

Abstract

The invention relates to a slab joint rubber strip waterproof device of an assembled building precast concrete slab, wherein the precast concrete slab comprises a first plate and a second plate arranged adjacently. The waterproof device is arranged at the slab joint between the first plate and the second plate, a first through groove is formed in the slab joint side of the first plate, a second through groove is formed in the slab joint side of the second plate, the first through groove and the second through groove are oppositely arranged and constitute an assembly area of the waterproof device, and the waterproof device forms at least two waterproof structures from the initial end to the tail end. The waterproof structure further comprises a first section bar and a second section bar assembled in the first through groove and the second through groove respectively, and a waterproof rubber strip matched with the first section bar and the second section bar, the waterproof rubber stripdeforms after extruding the section bars to form a waterproof barrier of the waterproof structure. Compared with the prior art, the device disclosed by the invention has the beneficial effect of effectively improving the waterproof performance of the precast concrete slab, thereby improving the quality of the precast concrete slab.

Description

technical field [0001] The invention relates to a waterproof device for a rubber strip for a slab seam, in particular to a waterproof device for a rubber strip for a slab seam of a prefabricated concrete slab in an assembled building. Background technique [0002] A building assembled from prefabricated parts on the site is called a prefabricated building. The curtain wall is the outer wall enclosure of the building. It is not load-bearing and hangs up like a curtain, so it is also called "curtain wall". A light wall with a decorative effect commonly used in buildings. The curtain walls of prefabricated buildings often use precast concrete slabs. However, after the precast concrete slabs are installed, there are often gaps between the slabs, which can easily lead to water leakage, reduce the life of the curtain wall, and cause the curtain wall to be easily damaged or even fall off. [0003] At present, in the usual design and construction, in order to achieve the purpose of...

Problems solved by technology

The curtain walls of prefabricated buildings often use prefabricated concrete slabs. However, after the precast concrete slabs are installed, there are often gaps between the slabs, which can easily lead to water seepage, reduce the life of the curtain wall, and cause the curtain wall to be easily damaged or even fall off.

[0003] At present, in the usual design and construction, in order to achieve the purpose of waterproofing the board seams, the traditional design is to reserve 15mm board seams, fill the board seams with foam rods, and use weather-resistant sealant glue technology, but this method is easy to cause board surface pollution. The glue surface is uneven, time-consuming and labor-intensive
