Post-pouring boundary beam integral type formwork structure and construction method thereof

Abstract

The invention discloses a post-pouring boundary beam integral type formwork structure and a construction method thereof. The post-pouring boundary beam integral type formwork structure comprises an upper supporting plate and a lower supporting plate, the upper supporting plate and the lower supporting plate are horizontally arranged, the upper supporting plate is used for being erected on a floor slab connected with an boundary beam to be poured, a supporting part is formed by the portion, overlapped with the floor slab, of the upper supporting plate, and the part overhung outside the floor slab forms a mounting part; a lifting ring is arranged on the upper side of the upper supporting plate; an integral boundary beam formwork is detachably mounted on the lower side of the mounting part; the lower supporting plate is used for being erected on the floor slab on the lower layer of the boundary beam to be poured, a first supporting rod is arranged on the upper side of the lower supporting plate, the upper end of the first supporting rod is connected with the lower side of the boundary beam formwork, and the lower end of the first supporting rod is connected with the lower supporting plate; and a pouring opening is further formed in the upper supporting plate and used for pouring concrete into the boundary beam formwork. The construction method is convenient and fast to construct, simple to operate, high in pouring quality, integrally hoisted, convenient to recycle and good in benefit.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a post-cast edge beam integral formwork structure and a construction method thereof. Background technique [0002] At present, the domestic traditional wooden formwork cast-in-place structure still occupies a large proportion. Side beams and formwork at side beam hanging formwork are often reinforced with wire-bound side beam reinforcement, especially for post-cast side beams, the structure of wire-bound side beam reinforcement has the following defects: (1) Disturbance is easily generated during the concrete pouring process, As a result, the steel bars of the side beams are displaced and the side molds are displaced, resulting in poor quality of concrete pouring of the side beams. The pouring height of the concrete slab cannot use matching slab thickness control parts, and the thickness control accuracy is low, which affects subsequent decoration and curtain wall ...

Problems solved by technology

Side beams and formwork at side beam hanging formwork are often reinforced with wire-bound side beam reinforcement, especially for post-cast side beams, the structure of wire-bound side beam reinforcement has the following defects: (1) Disturbance is easily generated during the concrete pouring process, As a result, the steel bars of the side beams are displaced and the side molds are displaced, resulting in poor quality of concrete pouring of the side beams. The pouring height of the concrete slab cannot use matching slab thickness control parts, and the thickness control accuracy is low, which affects subsequent decoration and curtain wall construction; (2) At the same time, the iron wire is used to tie the side beams, and the corrosion of the iron wires in the later period is likely to cause water seepage, and additional waterproof maintenance work is required in the follow-up; (3) The construction of the iron wire tie is simple, and it remains in the pouring body after the construction is completed, which cannot be recycled.
