Embodiment Construction

[0010] Embodiments of the present invention: according to the specific conditions of old and new building foundations, according to the attached figure 2 Make a waterstop (1) according to the requirements. Clean the old concrete structural surface first, and chisel it slightly, and then paste one end of the waterstop (1) on the old concrete structural surface with waterproof structural adhesive. The other end of (1) is put in place, and the new structure is poured. After the expansion joint is removed from the formwork, lay the caulking material (4) on the top and bottom of the waterstop (1), put the expansion strip (2) on the water-facing surface of the caulking material (4), and finally place the expansion strip (2) Fill the caulking material (3) to form a complete expansion joint waterproof structure. Waterstop (1) is made of 3mm stainless steel plate, and expansion strip (2) is made of rubber, and this rubber has the performance of water swelling.

Abstract

The invention relates to a waterproof structure of new and old concrete construction interface flexible seam. Wherein, one end of waterproof band is adhered on the oil concrete surface, while another end is inserted into new construction; the waterproof band is around with stuffing material; and expansion bars are laid on the stuffing material; and the embedding material is laid on the expansion bars. The invention has better waterproof effect, to improve the construction quality, and it can be used in underground construction or ground construction that needing waterproof property.

Description

Technical field: [0001] The invention relates to a waterproof method and structure of concrete buildings. Background technique: [0002] In the transformation and expansion of concrete construction projects, it is often encountered that new concrete buildings are built next to the existing concrete projects, including the extension of buildings such as pit walls, corridors and floors. The expansion joint waterproof structure used at the junction of old and new buildings requires not only meeting the needs of expansion and contraction, but also meeting the needs of waterproofing. Since the expansion joints used in new construction in the past are pre-buried structures of buried waterstops, they cannot extend into the structure of old buildings, and cannot form effective waterproof structure nodes. As a result, the quality of buildings is often affected and left Unsafe hidden dangers, or even undue losses. Invention content: [0003] The object of the present invention is ...
