Abstract

The invention discloses a steel-wood combined formwork structure of shear walls on two sides of a deformation joint and a construction method of the steel-wood combined formwork structure. The construction method comprises the steps of constructing the shear wall on the first side of the deformation joint, binding the reinforcement structure of the shear wall on the second side, mounting a first formwork on the inner side of the reinforcement structure, fixing a plurality of nuts on the outer side of the first formwork and forming first diagonal pulling screw holes in the first formwork correspondingly to the nuts, mounting a second formwork on the outer side of the reinforcement structure and forming second diagonal pulling screw holes in the second formwork, putting fastening screws through the first and second diagonal pulling screw holes so that the first ends of the fastening bolts are screwed down with the nuts, fastening the second ends of the fastening bolts with the second formwork so that the first and second formworks are fastened to the two sides of the reinforcement structure, pouring concrete and stripping off the formworks. A one-way fastened formwork structure is formed on the inner sides of the shear walls at the deformation joint by use of the one-way fastening screws matched with the nuts, and therefore, the problem that the formworks cannot be supported and stripped on the inner sides of the walls of the deformation joint is solved. As a result, the rigidity of each formwork is improved, and the perpendicularity and the thickness uniformity of each wall of the deformation joint are greatly improved.

Description

The steel and wood composite formwork structure of a kind of deformation joint both sides shear wall and construction method thereof
Technical field
The present invention relates to a kind of construction of shear wall, particularly relate to steel and wood composite formwork structure and the construction method thereof of a kind of deformation joint both sides shear wall.
Background technology
For preventing building from occurring differential settlement, arrange through vertical clearance gap at difference place, building being divided several can the separate unit of free settling, and therefore in building, we can see various deformation joint.But deformation joint width is general, and only 100 ~ 150mm is wide, in narrow space place deformation joint, how the template of side is propped up, is torn open and just become a difficult problem, routinely a mold method, cannot prop up and tear open, and have to be discarded in seam.So not only cause waste, and affect the action effect of deformation joint.For not affecting the effect of deformation joint, generally do template with plastic foamboard, this material is not only expensive, and can only single use, causes very large waste.
The way of current routine is, as shown in Figure 1, adopt and fill with deformation joint 21 clear span with thick foamed material and combined plate in deformation joint 21, then utilize screw rod 22 through foamed material and combined plate, utilize the screw hole of the side shear wall 23 of having constructed to drawing the template 25 of reinforcing side to be built shear wall 24, finally at foamed material and concreting between combined plate and template 25, shaping and deformation stitches the shear wall of 21 both sides.
This method is foamed material and combined plate etc. due to what fill in deformation joint 21, and rigidity is inadequate, concrete placings and vibrate in process, lateral pressure is very large, thus causing the degree of gravity vertical forwall surface deviation of deformation joint both sides shear wall excessive, body of wall became uneven, after form removal, perception is very poor.In order to address this problem, we propose a kind of Novel steel wood gang form structure as the construction at deformation joint wall column side form.Thus improve stability, the reliability of two side templates, be also convenient to remove simultaneously.
