Deformation joint shear wall template structure and template supporting construction method Technical Field The application relates to the field of building construction, in particular to a deformation joint shear wall template structure and a template support construction method. Background Shear walls are also known as wind-resistant walls, shock-resistant walls or structural walls. Wall bodies in houses or structures mainly bear horizontal load and vertical load (gravity) caused by wind load or earthquake action, and prevent structural shearing (shearing) damage. The building often deforms under the action of external factors, resulting in cracking or even destruction. The deformation joint is a reserved structural joint for the situation, and is a generic term of an expansion joint, a settlement joint and a shockproof joint. The shear wall is generally a reinforced concrete structure, and when the shear wall is cast, the formwork needs to be supported. The template structure of the shear wall mainly comprises a template, a wood beam, a steel pipe, a split bolt component and a steel pipe connecting fastener, wherein the wood beam and the steel pipe are arranged on one side of the template far away from a pouring area, the template comprises an inner template corresponding to the indoor side of the shear wall, an outer template corresponding to the outdoor side of the shear wall and an edge template corresponding to the corner side of the shear wall, the inner template and the outer template are fixed in a split mode by the split bolt component, and the edge template is fixed after the steel pipe corresponding to the edge template is connected with the steel pipe corresponding to the inner template and the outer template by the steel pipe connecting fastener. When the deformation joint of the shear wall is narrow and the shear wall is poured, the installation difficulty of the wood beams and the steel pipes on the back of the side template close to one side of the deformation joint area of the shear wall is high, and sometimes the condition that the wood beams and the steel pipes cannot be simultaneously placed in the deformation joint area exists, so that the support and fixation work of the side template of the shear wall to be poured is difficult to carry out, the side template of the shear wall close to the deformation joint area is easy to have the condition of poor support and design, and the pouring construction quality of the shear wall is influenced. Disclosure of Invention In order to solve the problem that a template of a shear wall close to a deformation joint area is difficult to support and fix, the application provides a deformation joint shear wall template structure and a template supporting construction method. The deformation joint shear wall template structure and the template support construction method provided by the application adopt the following technical scheme: The deformation joint shear wall template structure comprises templates, wherein the templates jointly surround to form a pouring area, each template comprises an inner template, an outer template, a second side template and a first side template, the first side template corresponds to the area where the deformation joint is located, the templates surround to form the pouring area, the surfaces of the templates, which deviate from the pouring area, are defined to be back surfaces, the back surfaces of the inner template and the outer template are respectively provided with a plurality of wood beams and a plurality of groups of steel pipes, the steel pipes are located on one side, far away from the pouring area, of each group of steel pipes, the number of the steel pipes is two, the steel pipes on the back surface of the inner template are parallel to each other, each group of steel pipes on the back surface of the inner template respectively correspond to one group of steel pipes on the back surface of the outer template, the corresponding two groups of steel pipes are jointly connected with a plurality of pull bolt assemblies, the back surface of the first side template is provided with a pressing plate, the steel pipes on the back surface of the inner template are in threaded connection with nuts, the steel pipes on the back surface of the outer template are in threaded connection with nuts, and the nuts are used for pressing the side edges of the pressing plate.
