A post-cast tool-type formwork with convenient assembly and disassembly

Abstract

The invention discloses a post-cast strip tool type template convenient to assemble and disassemble, and relates to a device for building construction. The post-cast strip tool type template comprises two template bodies at opposite positions, wherein a telescopic template supporting device is arranged between the backs of the two template bodies; the telescopic template supporting device comprises two pin roll supports, two supporting rods and two threaded sleeves; the two pin roll supports are respectively arranged at the backs of the two template bodies; a pin hole is respectively formed in the two pin roll supports; one ends of the supporting rods are respectively inserted into the two pin holes; the other ends, which are not inserted into the pin holes, of the two supporting rods are respectively provided with positive and negative threads; the two threaded sleeves respectively comprise a shaft sleeve provided with the threads and a fixed plate connected with the shaft sleeve; the two threaded sleeves are respectively connected with the ends, which are not inserted into the pin holes, of the two supporting rods through respective shaft sleeves; the fixed plates of the two threaded sleeves are butt jointed by a fixing device, so that the two supporting rods are connected between the backs of the two template bodies. The post-cast strip tool type template has the advantage that the template is easy to assemble and disassemble and can be used in a turning manner, the construction cost is reduced, the working efficiency is improved and the like.

Description

technical field [0001] The invention relates to a device for building construction, in particular to a formwork for pouring concrete. Background technique [0002] At present, in the design of cast-in-place reinforced concrete frames, considering the influence of temperature difference stress and uneven settlement of the foundation on the structure, most of them adopt indwelling post-casting strips, and indwelling post-casting strips are left on the foundation bottom plate and some positions that require waterproofing. Steel plate waterstop is also set in the middle, and this brings great difficulty to construction assembly and disassembly formwork, especially after foundation base plate 35 installs waterstop, cannot formwork removal at all. Such as Figure 14 As shown, during construction, double-layer steel wire mesh 33 or fast and easy closing nets are used on both sides of the reserved post-casting belt 30, and steel skeletons 32 and steel support 34 are added to the upp...

AI Technical Summary

Problems solved by technology

There are following deficiencies in the above prior art scheme: 1, no demolition process In order to achieve the purpose of no grout leakage and effective combination with post-pouring concrete, double-layer steel wire mesh is used to block, the steel skeleton adds steel support, and is welded on site. Fixed, troublesome construction, high labor intensity and low work efficiency; 2. The steel wire mesh and steel skeleton are buried in the concrete at one time, which wastes a lot of steel and increases the construction cost; Relatively poor, the geometry of the poured tape after indwelling is poor
