Embodiment 1

[0024] First carry out the construction of the foundation beam structure. In the construction of the foundation beam structure, grooves 3-1 are arranged on both sides of the foundation beam cushion 3, and the bottom of the cement board formwork 2 is inserted in the groove 3-1 and the bottom side of the cement board formwork The top of the wall is on the inner edge of the groove to control the positioning of the bottom of the cement board form. The construction steps of the groove are as follows: before the initial setting of the concrete of the foundation beam cushion 3, the wooden strips are pressed, so that the elevation of the upper surface of the wooden strips is consistent with the concrete elevation of the foundation beam cushion 3, and the release agent is applied on the wooden strips for removal. . After the initial setting of the concrete on the cushion of the foundation beam, lift out the reserved wooden strips, clean up the sawdust, and form the groove 3-1.

Abstract

The invention discloses a floor slab waterproof protective layer construction method. First, foundation beam structure construction is conducted. In the foundation beam structure construction, grooves are formed in the two sides of a foundation beam cushion layer. Bottoms of two cement slab templates are respectively inserted in the groove in the corresponding side. The construction steps after the foundation beam structure construction is finished are as following: (1) detaching inner supporting wood beams; (2) laying waterproof roll layers so as to form side wall waterproof roll layers, a foundation beam cushion layer waterproof roll layer and a base plate cushion layer waterproof roller layer; (3) respectively installing fixing cement slabs on the inner side wall of the side wall waterproof roller layers on the left side and the right side; (4) forming an inner support; (5) pouring foundation beam waterproof protection layer concrete on the foundation beam waterproof roll layer, and pouring base plate waterproof protection layer concrete on the base plate cushion layer waterproof roller layer. The vertical face water protection layer formed by the adoption of the method is firm, stable, and not easy to come off, and plays an effective role in protecting the waterproof layer in base plate construction.

Description

technical field [0001] The invention relates to a construction method for a foundation waterproof protection layer, in particular to a construction method for a foundation beam cement board waterproof protection layer. Background technique [0002] With the continuous rapid development of the social economy, all walks of life are sparing no effort to increase speed, maintain quality, and reduce costs, especially in the construction industry. In the past foundation projects, the traditional brick tire formwork construction technology was adopted, which required a large labor input, high labor costs, and technical intervals in wet operations such as plastering, which resulted in extended construction periods; the foundation beams and caps were protected by traditional plastering for the waterproof protection layer. Ash (concrete), etc., are easy to crack and fall off, resulting in damage to the waterproof layer and affecting the waterproof quality. Cement board has good machi...
