Multipurpose mold plate for cast-in-situ concrete

Abstract

A multipurpose mold plate for cast-in-situ concrete comprises an upper sealing cover plate (1), a periphery panel (2), a lower sealing cover plate (3), a supporting middle axis rod (4), scissor rods (5), clamping openings (6) and supporting edge rods (7). The multipurpose mold plate is characterized in that firstly, every two rods form one scissor rod (5); secondly, the two or more sets of scissor rods (5) are connected with the two ends of the supporting middle axis rod (4) to form an I-shaped framework; thirdly, the I-shaped framework and the supporting edge rods (7) are assembled into a box-shaped framework through the clamping openings (6); and fourthly, the box-shaped framework, the upper sealing cover plate (1), the periphery panel (2) and the lower sealing cover plate (3) are connected to be folded into an integrated hollow body in a sealed mode. The multipurpose mold plate for the cast-in-situ concrete has the advantages of being easy to install, high in production efficiency, low in construction cost, high in shock resistance, crack resistance, pressure resistance and overall hardness and the like and is a ribbed slab, a solid large plate, a bridge engineering plate, an assembly type folding plate and the like capable of adapting to modern architectures and mechanized production.

Description

technical field [0001] The invention relates to a pre-set formwork used in cast-in-place floor and bridge engineering construction, and a cast-in-place concrete multipurpose formwork. Background technique [0002] At present, cast-in-place concrete floors are widely used, and the application number is 200610008747.7, which is a utility model technology disclosed as "a membrane shell component". The wall and the lower base plate form a hollow body, which is characterized in that there is a light material block in the cavity enclosed by the upper plate, surrounding side walls and lower base plate to form a solid whole with the upper plate, surrounding side walls and lower base plate. However, when this type of membrane shell component is applied to the floor, the membrane shell cannot be accurately arranged at the middle layer of the floor, which affects the construction quality of the floor. However, the strength of the outer surface of this type of membrane shell member is ...

Problems solved by technology

However, when this kind of membrane shell component is applied to the floor, the membrane shell cannot be accurately arranged in the middle layer of the floor, which affects the construction quality of the floor

However, the strength of the outer surface of this type of membrane shell member is not enough. Even if cement or cement mortar or cement fiber or cementitious material reinforcement or net is used, the outer surface will still be damaged during actual handling, stacking, transportation, installation and construction. It is easy to be damaged, and in severe cases, the appearance of the internal solid lightweight material components will be damaged, and the impact resistance is not ideal
