Description
Technical Field
The utility model relates to a formwork support technical field, concretely relates to formwork support system for movement joint both sides shear force wall.
Background
For the narrow space of the building concrete structure, such as the deformation joint in the double shear wall, because the space of the deformation joint is narrow, some template supporting pieces are required to be used for supporting when the shear wall is constructed, and therefore the width of the deformation joint is ensured. However, for the traditional formwork support piece, the batten or the foam material is mainly used for being clamped between the two inner side formworks, and the problem is that after concrete pouring of the shear wall is completed, self stress in the concrete curing process can generate expansion action on the side formwork, so that the side formwork is easy to expand, concrete overflows out of the side formwork and finally flows into a deformation joint. And under the two-way extrusion effect of both sides shear force wall, traditional flitch or extrusion molding cystosepiment are pressed from both sides tightly and are difficult for taking out, and foam or flitch occupy the space of movement joint, can influence the service function of follow-up movement joint.
Although, also there are some detachable strutting arrangement to place between two shear force walls among the prior art, provide the supporting role for the inboard template of shear force wall, follow-up dismantlement used repeatedly that also can realize strutting arrangement like this, chinese patent that publication number is CN106088581A discloses an adjustable template structure that building wall structure seam was pour and is used, solves the narrow and small template that causes in template supporting space and struts the difficulty and template and strut the technical problem that size precision is low, and technical scheme is: and an adjusting device is arranged between the two symmetrically arranged templates, and two ends of the adjusting device are respectively hinged with the two templates. The adjusting device comprises: the adjusting screw rod is a screw rod with reverse threads at two ends, the pair of mobile control plates are in threaded connection with two ends of the adjusting screw rod respectively, two ends of each mobile control plate are in hinged connection with the two supporting plates respectively, and the other ends of the two supporting plates are in hinged connection with the two templates respectively.
Although the adjusting device has a simple structure, the distance between the two templates is convenient and accurate to adjust, the two templates are mutually supported without other auxiliary supports, and the supporting and the dismounting are convenient. However, the wall height and the wall length of the shear wall are two to three meters long, and the width of the deformation joint is only about 200mm, so that the operation space is limited in the narrow space, workers cannot uniformly place the adjusting devices between the inner side forms of the two shear walls, and can only install and place the adjusting devices at the left side, the right side, the upper end and the lower end of the inner side form plates of the two shear walls.
SUMMERY OF THE UTILITY MODEL
To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: the utility model provides a template braced system for movement joint both sides shear force wall has solved the problem that the shear force wall inside form board established inefficiency, has the advantage that makes things convenient for the later stage to demolish, and repeatedly usable has practiced thrift construction cycle greatly.
In order to solve the technical problem, the utility model discloses a following technical scheme:
a template supporting system for shear walls on two sides of a deformation joint comprises two outer side templates positioned on the outer sides of the two shear walls and two inner side templates positioned on the inner sides of the two shear walls, wherein at least two vertical inflatable elastic bags are arranged between the two inner side templates along the length direction of the two inner side templates; the bag extends vertically along the height direction of the inner side template and is arranged at the same height with the inner side template; the two outer side templates are reinforced by penetrating a plurality of opposite pull rod, and the adjacent bags are arranged at intervals to be staggered with the opposite pull rod.
