Abstract

The invention discloses an L-shaped opening permanent beam formwork. The present invention includes an L-shaped upper template body and an L-shaped lower template body. Limiting holes are provided at both ends of the bottom surface of the L-shaped upper template body, and a bottom surface of the L-shaped lower template body is provided with a limiter hole matched with the limiting holes. Limiting key, a group of occlusal holes are arranged in the middle of the bottom surface of the L-shaped upper template body, and a group of occlusal keys matched with the occlusion holes are arranged in the middle of the bottom surface of the L-shaped lower template body. The L-shaped lower template body The upper part is provided with a slurry tank, and the screw rods pass through the screw holes on the side walls of the L-shaped upper template body and the L-shaped lower template body and are fixed by nuts. The invention can improve the unfavorable factors of the traditional formwork, improve the durability of the structure, effectively reduce the space occupied by the formwork, and reduce the transportation cost.

Description

Technical field: [0001] The invention belongs to the technical field of building construction, and in particular relates to an L-shaped open-type permanent beam formwork, specifically an L-shaped high-durability permanent beam formwork mainly used in hydraulic structures, harbor and sea structures, industrial and civil buildings, etc. The beam composite formwork is used as a formwork in the pouring stage, and it also serves as the protective layer of the beam and participates in the structural work after the pouring is formed. Background technique: [0002] In the field of building construction, the pouring of reinforced concrete beams usually relies on wood formwork or steel formwork. Wooden formwork is low in cost, light in weight, and easy to install and construct, but its turnover rate is low, its life is short, and it is difficult to recycle and reuse, which brings a burden to the environment. The turnover rate of steel formwork is high, the quality of concrete forming...
