Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a roof parapet wall stereotyped and stretchable template reinforcement device. Background Art

[0002] During the construction of housing projects, a high parapet is often set up on the roof. The roof parapet refers to the vertical dry hanging structure connecting the roof and the wall of the house. Because of its beautiful shape, it is also called the roof hanging line. It not only has a certain decorative effect, but also prevents rainwater from flowing into the room along the wall, playing a waterproof role. During the civil construction stage, the parapet of the cast-in-place structure needs to be constructed by throwing reinforcement, hanging formwork, and post-pouring on the roof structure board when pouring the roof structure concrete. The traditional roof parapet reinforcement method is to use wooden plywood as the formwork, wooden beams as the secondary keel, and steel pipes as the main keel, and connect the formwork, wooden beams, and steel pipes together through water stop bolts for reinforcement and fixation. After the above work is completed, since there is no support point for diagonal bracing reinforcement on the lateral side, it is necessary to set a large number of pre-buried steel bars or steel pipes at a certain distance on the roof structure board as diagonal bracing fixing points. Then use steel pipes to brace the parapet formwork for lateral reinforcement. The defects of the above approach are: the quality of reinforcement molding is poor, and the flatness of the wall facade is difficult to meet the requirements; the embedded steel bars or steel pipes need to be cut and processed later, and waterproof reinforcement treatment is required. If the treatment is not in place, the risk of roof leakage will increase. Utility Model Content
