Shear wall formwork inner stay and tie bar combined component and method

Abstract

The invention belongs to the technical field of building construction, and in particular relates to a combined member of a shear wall formwork inner stay and a tie bar, which includes a cement inner stay and a tie bar, and both ends of the tie bar are bent upwards to form a A hook, one end of which is a 90° hook, and the other end is a hook greater than 90° and less than 180°; the cement inner stay is a long strip structure, and a notch is provided on the upper surface of its two ends; The middle part of the tie bar is pre-buried in the cement inner stay, the hooks at both ends of the tie bar face upward and are located outside the notch of the corresponding end, and the hooks at both ends of the tie bar are connected to the upper part of the cement inner stay. Surfaces are angled at an angle. In the present invention, the cement inner stays and tie bars are made into one component to form a whole, which not only satisfies the function of formwork inner support and steel bar tie, but also reduces the space occupancy of the transverse member in the shear wall, and reduces the time when the vibrating rod is inserted. The obstruction reduces the difficulty of on-site construction; greatly saves labor and improves construction efficiency.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a combined component and method of internal stays and tie bars in a shear wall formwork. Background technique [0002] At present, in the existing shear wall structure process, the formwork installation adopts the fixing measures of pulling the tension screw outside and the cement inner stay inside, and the reinforcement on both sides of the shear wall adopts tie bars. During the concrete pouring and vibrating process, transverse members such as inner stays and tie bars seriously hinder the insertion of the vibrating rod, and when the vibrating rod touches the inner stay, it is easy to damage the inner stay, resulting in the loss of the inner part of the formwork. The support force causes the local forming size of the shear wall to be too small, which affects the construction quality. Contents of the invention [0003] In view of the above-mentioned t...
