Problems solved by technology

[0002] There are many construction methods for the current roof anti-leakage protective layer, such as the three-oil two-felt method and the concrete grid method. Take out wooden strips or metal strips in the expansion joints between the squares, fill them with fine sand first, and then fill them with sealant. Although these two methods have a certain anti-leakage effect, the common disadvantage is that the construction method is complicated. , high cost

Embodiment Construction

[0006] The construction method of the present invention is 1., at first to the cement cover board that needs to be constructed and the wall joints in the following 13-26 centimeters, the board joints are filled with cement mortar, and the proportioning ratio of its cement and mortar is 1: 2; 2. Construct the roof protective layer on the cement cover plate after the caulking, and its material ratio is the concrete protective layer made of 1 part of cement, 2 parts of large sand, and 3 parts of 0.5 centimeter stones, the thickness is 8-10 centimeters, and its flatness is The middle high side is low, with a slope of 3-6 degrees. ③. Within 5-48 hours after the protective layer is completed, draw a number of main expansion joints on the upper surface of the protective layer corresponding to the cement cover and the wall, and then take the average number between the main expansion joints to draw auxiliary joints. For expansion sutures, the distance between various expansion sutures ...

Abstract

The invention provides a method for constructing a roof intrusion-proof protective layer. The construction method comprises the following steps that: (1) a cement cover board to be constructed and the following wall slot with a depth of ranging from 13 to 26 centimeters and a board slot are infilled with cement mortar; (2) the cement cover board is used to construct the roof protective layer with a planeness of high middle and low side and with a gradient of ranging from 3 to 6 degrees; (3) within 5 to 48 hours after the protective layer is made, a plurality of main dilatation joint lines are marked out on the upper surfaces of the cement cover board and the protective layer corresponding to a wall body, each main dilatation joint line is averaged to mark out auxiliary dilatation joint lines and then a cutting machine is used to cut V-shaped grooves with a depth of 4 to 6 centimeters along the main dilatation joint lines and the auxiliary dilatation joint lines, the width of an upper opening of the V-shaped groove is 1 centimeter; (4) the bottom of each V-shaped groove is filled with fine sand, a layer of waterproof fluid sealant with a thickness not less than one centimeter is stuck on the fine sand, and an upper edge of the V-shaped groove had better be provided with a slightly hollow part. The construction method of the invention is easy and simple to operate, good in effect, long in age limit and easy to popularize.

Description

Technical field: [0001] The invention relates to a roof covering layer, in particular to a construction method of a roof anti-leakage protective layer with simple process, low cost and good waterproof effect. Background technique: [0002] There are many construction methods for the current roof anti-leakage protective layer, such as the three-oil two-felt method and the concrete grid method. Take out wooden strips or metal strips in the expansion joints between the squares, fill them with fine sand first, and then fill them with sealant. Although these two methods have a certain anti-leakage effect, the common disadvantage is that the construction method is complicated. , High cost. Invention content: [0003] The purpose of the invention is to design a construction method of the roof protective layer with simple process, low cost and good anti-leakage effect. [0004] The technical solution of the present invention is accomplished in the following manner, and it is cha...
