Embodiment 1

[0030] like figure 1 The shown shear wall formwork and the pull screw, including shear wall plate 1, inner wall plate 2, outer formwork 3, pull screw 4, lock nut 5 and plastic sleeve 6;

[0031] Among them, the shear wall panel 1 is a concrete structure; the inner formwork 2 is the inner support formwork during the pouring construction of the shear wall panel 1; the outer formwork 3 is the outer support wall panel during the pouring construction of the shear wall panel 1; The screw 4 is provided with an external thread, and the pulling screw 4 penetrates through the shear wall panel 1, the inner wall panel 2 and the outer wall panel 3, and the two ends of the pulling screw 4 are threadedly connected with a locking nut 5; The pitch is consistent with the pitch of the paired screw 4. During operation, the position and spacing of the template are fixed by connecting the two ends of the paired screw 4; the plastic sleeve 6 is sleeved on the outside of the paired screw 4, and the l...

Abstract

The invention provides a method for sealing high-rise shear wall external wall upstream face pulling screw holes. PVC plastic conical plugs are additionally arranged, the PVC plastic conical plugs areused in the external wall shear wall pulling screw holes and inserted into the pulling screw external holes for sealing, then a foaming filler is injected from the positions, located on the inner side of a shear wall, of the pulling screw holes, and then the shear wall pulling screw holes are sealed by means of combination of inside and outside. It is ensured that the outer ends of the pulling screw holes are tightly filled with the tail ends of the PVC plastic conical plugs and the tail ends of the PVC plastic conical plugs are completely attached to a shear wall external wall, and meanwhile, conical plug anti-slip layers can effectively adhere to cement mortar. The method for sealing the high-rise shear wall external wall upstream face pulling screw holes is simple to implement and convenient to operate, leakage situation due to the high-rise external wall is greatly reduced, the maintenance cost is reduced, the construction quality is improved, and the method solves the problem ofexternal wall seepage due to poor sealing of the pulling screw holes, rough and uneven external wall ends of the pulling screw holes or aging of foaming materials caused by a conventional screw hole sealing method.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a method for plugging the water-facing pull screw holes of an outer wall of a high-rise shear wall. Background technique [0002] At present, in the construction of concrete structure pouring, it is basically shear wall and frame structure, but in civil buildings, there are many shear wall structures. In the process of formwork support, shear wall involves a large number of tension screw construction. After the shear wall board is poured and the formwork is removed, there will be a large number of screw holes in the inner and outer walls. At present, the screw holes in the inner wall are generally sealed with mortar during the plastering process, and the screw holes in the outer wall are both The injection of foaming filler is used as a plug. [0003] However, the density of the foamed material is low and the structure is fragile, and the external wall seepage c...
