Building cornice double-water-drip-line formwork and construction method thereof

Abstract

The invention relates to the field of architectural engineering construction, and particularly discloses a building cornice double-water-drip-line formwork and a construction method thereof. The building cornice double-water-drip-line formwork comprises a building outer cornice formwork body, and is characterized in that a groove is formed in the bottom formwork edge of the building outer cornice formwork body, and an aluminum alloy bar is arranged in the center of the groove. According to the building cornice double-water-drip-line formwork and the construction method thereof, working procedures are simple, the technology is easy to grasp, two small working procedures are added in the formwork assembling process, the occupied time is not large, and due to the fact that the formwork and a structural part are cast in situ through one-time forming, the phenomena of disengaging and cracking in a later period can be avoided.

Description

(1) Technical field [0001] The invention relates to the field of building engineering construction, in particular to a formwork with double driplines at the cornice of a building and a construction method thereof. (2) Background technology [0002] At present, there are generally two ways to drip water from the eaves of construction projects: rear drip line and cast-in-place drip line. In the structural construction stage, the stereotyped hole formwork is used, and the position of the drip line is calculated, and the drip line and the door and window openings are poured together as a cast-in-place drip line. There are three methods for the post-drip line: (1) flat drip line, using mortar in the A 4cm wide and 1cm thick drip line is wiped out at the bottom of the cornice; (2) the slope drip line (commonly known as the eagle beak), the method is basically the same as the flat drip line, but the shape is different; (3) the sticky drip groove is used at the bottom of the cor...

Problems solved by technology

[0004] (1) This method of second-time sticking and wiping the drip line on the concrete structure in the later stage is relatively cumbersome in construction

First of all, a series of treatments must be carried out on the base surface of the structure, such as surface cleaning, "texturization treatment" or slurry removal, and then start to wipe the drip line and glue the drip tank. Workers work for half a day. The entire substation has hundreds of windows, dozens of canopies, and hundreds of meters of overhanging eaves that need to be dripped. This method consumes a lot of workers and time.

[0005] (2) The process is difficult to control

The drip line is made at the bottom of the structure, and it is constructed on the back during the sticki
