Description

Inter-column shear wall reinforcing system for assembly type formwork and construction method Technical Field The invention relates to the technical field of constructional engineering, in particular to an inter-column shear wall reinforcing system for an assembly type template and a related construction method. Background In the current construction site shear wall pouring, assembled templates, such as aluminum templates, plastic templates and other new material templates, are often adopted. The formwork system generally comprises a panel and a reinforcing and supporting system, and has the advantages of convenience in construction, high construction efficiency, reusability of the formwork and the like, and relates to the height drop of a construction working surface. In actual construction, casting of the inter-column shear wall is often encountered. In the pouring of such components, a reliable restraint system cannot be formed by a reinforcing support system (such as a back rib, a counter-pulling screw, an inclined support and the like) in the area of the wall form, so that a reliable restraint is formed by the back rib and a column hoop by means of a column, and the form is prevented from being exploded during pouring. In the above operation, since the cross-section width of the columns is generally larger than the thickness of the shear wall between the columns, the back edges need to be connected in a horizontal direction and connected in a corner (external corner and internal corner) during construction. At present, for splicing connection, groove-type node plates are often connected by opposite-pull screw extrusion passing through the groove-type node plates, most of the groove-type node plates are connected in a single-point mode, back edges are easy to be connected at splicing positions along the wall surface direction, so that deviation is caused in flatness of the wall surface, for external corner connection, a back edge right angle welding or opposite-pull screw mode is adopted, a right angle fixer is needed to be welded on the back edge when the opposite-pull screw is adopted, for internal corner connection, a direct welding mode is adopted, and the secondary utilization rate of the back edges is reduced. In addition, in the process of pouring the inter-column shear wall, the pouring speed of the shear wall is faster than that of the layer of building plates, so that after the pouring of the inter-column shear wall is finished, the process of pouring the upper layer of shear wall is required to be carried out after the pouring of the upper layer of building plates is finished, and the quick construction on site is not facilitated. Based on the method, in order to overcome the defects that the connection construction of a reinforcing system is complex and the pouring dependence of the construction process on the floor slab is strong when the inter-column shear wall is constructed by adopting the assembly type template at present, the inter-column shear wall reinforcing system facing the assembly type template and the related construction method are provided.
