Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing.

[0019] Such as figure 1 and figure 2 As shown, it is a shear wall formwork male corner tensioning device provided by the embodiment of the present invention, which includes a horizontal back flute 1 and a tension screw device 2, and the horizontal back flute 1 includes two mutually perpendicular flute bodies 3 , so that the horizontal back corrugated 1 is L-shaped, and the two corrugated bodies 3 are respectively fixed on the aluminum alloy templates on both sides of the male corners, and a steel plate seat 4 is fixedly installed on the ends of the two corrugated bodies 3 close to the male corners. The pull screw device 2 includes a screw 5 and a circular washer-type hexagonal nut 6. The screw 5 is sequentially interspersed in two steel plate seats 4 to connect the two steel plates, and a circular washer-type hexagonal nut is respectively arranged at both ends of the scre...

Abstract

The invention discloses a shear wall mold board external corner counter-pulling device which comprises a horizontal back strip and a counter-pulling screw device. The L-shaped horizontal back strip includes two strip bodies vertical to each other. The two strip bodies are fixed on the mold boards on two sides of an external angle. A steel plate seat is fixed at one end, close to the external angle, of each of the two strip body. The counter-pulling screw device comprises a screw and circular gasket type hexagonal nuts. The screw sequentially penetrates the two steep plate seats to connect the same. The circular gasket type hexagonal nuts for locking the mold boards on two sides of the external angle are disposed at two ends of the screw. By the shear wall mold board external corner counter-pulling device, mold expansion and mud leakage can be avoided, the shear wall concrete external corner is enabled to be angular, smooth and free of mold expansion, and concrete waste during construction is reduced greatly.

Description

technical field [0001] The invention relates to a device for pulling a pair of external corners of a formwork for a shear wall. Background technique [0002] Usually, in the process of using aluminum alloy formwork for shear wall concrete pouring, the external corners of the shear walls are often not reinforced firmly, resulting in mold expansion and grout leakage at the external corners of the poured shear wall structure, and waste Lots of concrete material. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a shear wall external corner pull-up device that can strengthen the external corner formwork and effectively improve the quality of concrete pouring. [0004] The technical solution adopted in the present invention is: a shear wall formwork external angle anti-tension device, which is characterized in that it includes a horizontal back flute and an anti-tension screw device, the horizontal back flute is L-shap...
