Construction method of foundation beam side facade waterproof structure

Abstract

The invention discloses a construction method of a foundation beam side facade waterproof structure. The construction method comprises the steps that the construction is carried out after excavation of a foundation beam groove is completed, foundation cushion layers are poured at the bottom and the tops of the two sides of the foundation beam groove, and grooves are formed in the two ends of eachbottom foundation cushion layer; cement board blank films are placed in the grooves; waterproof rolls are laid on the inner side walls, the tops and the bottom plate foundation cushion layers of the cement board blank films; grid cloth is laid on the waterproof roll layer on the side wall of a foundation beam on each side, and the two ends of the grid cloth are in lap joint with the waterproof roll layers; and mortar is smeared into the grid cloth, the fullness of the mortar is 100%, and finally the grid cloth and the mortar plaster are combined to form the foundation beam side facade waterproof protection layer. The problems that the cross section of the beam is reduced, and pouring construction and beam bottom plate concrete light receiving construction are inconvenient are effectively solved. The construction method of the foundation beam side facade waterproof structure is convenient to construct, high in applicability, firm, stable and not prone to falling off or cracking, simplifies the structure and procedures, saves the cost, and can guarantee the quality and construction safety at the same time.

Description

technical field [0001] The invention relates to a construction method for a waterproof structure of a beam, in particular to a construction method for a side elevation waterproof structure of a cement board of a foundation beam. Background technique [0002] In recent years, with the rapid development of urban construction, underground structures in housing construction have become more and more common, and higher and higher requirements for waterproofing have been put forward. At present, in the common construction technology of waterproof protective layer in China, the protective layer of waterproof layer on both sides of the beam is protected by cement board, such as figure 1 As shown, the traditional construction process is: after the excavation of the foundation beam groove is completed, the foundation cushion is poured at the bottom of the foundation groove and the tops on both sides; cement slab tires are respectively placed in the grooves 2 at both ends of the founda...
