Limiter for inner and outer formworks

Abstract

The invention discloses a limiter for inner and outer formworks. The limiter comprises a pair of limiting arms and a connecting piece, wherein each limiting arm is provided with a press block capable of rotating in the horizontal plane; each press block has a longitudinal contact surface contacted with the side surface of a formwork; each limiting arm is provided with a connecting part connected with the connecting piece; the two limiting arms are arranged oppositely, the connecting parts of the two limiting arms are simultaneously detachably connected with the connecting piece, and during use, the two opposite press blocks clamp the inner and outer formworks respectively to limit the inner and outer formworks. The limiter for the inner and outer formworks has the advantages of high universality, capacity of repeated circulating use and convenience in mounting and dismounting while limiting the inner and outer formworks, and further, the limiter has an auxiliary function of keeping the whole shape of each formwork, does not have disturbance on concrete when dismounted, and facilitates finished product protection.

Description

technical field [0001] The invention belongs to the field of concrete structure construction, and in particular relates to a device for limiting the position of internal and external formwork. Background technique [0002] In the construction of concrete structures, for the limit of the inner and outer molds that are poured at the same time as the cast-in-place concrete slab, there are currently no finalized products and relatively fixed construction techniques, which mainly rely on the skills and experience of skilled workers. The common practice is to use nails to pull wooden strips or use iron wires to tie knots. [0003] The technical defect of above-mentioned common way is: [0004] First, depending on the experience of workers, it is often difficult to effectively control the quality of concrete molding, and at the same time, the effect is slow; [0005] Second, the deflection of the demolition is likely to be detrimental to the protection of the finished cast-in-pla...

Problems solved by technology

[0004] First, depending on the experience of workers, it is often difficult to effectively control the quality of concrete molding, and at the same time, the effect is slow;

[0005] Second, the deflection of the demolition is likely to be detrimental to the protection of the finished cast-in-place concrete structure, ranging from missing edges and corners to cracks;

[0006] Third, it causes waste of turnover materials
