Description

Assembled grout leakage prevention steel template for concrete structure pouring Technical Field The utility model belongs to the technical field of building construction, and particularly relates to an assembled grout leakage preventing steel template for concrete structure pouring. Background The template is a temporary supporting structure and is manufactured according to design requirements, so that the concrete structure is molded according to the specified position and geometric dimension, and the correct position of the concrete structure is maintained. The template engineering is carried out to ensure the concrete engineering quality and construction safety, accelerate the construction progress and reduce the engineering cost. In the prior art, for concrete column pouring construction, a wood formwork is usually selected for supporting so as to pour concrete into a required column pile structure. The method has the following problems that 1) the wooden templates are extremely complex to set up and disassemble, the time consumption is long in the practical process, the turnover performance is poor, the construction period and the cost reduction are not facilitated, obvious challenges and constraints are formed for construction efficiency, cost control and building quality guarantee, 2) gaps are formed between the wooden templates and the ground, in the use process, the poured concrete flows out from the gaps to the outside, namely, slurry leakage or slurry leakage occurs, so that the appearance quality of a column formed by the concrete is poor, 3) the wooden templates are weaker in structural integrity and are greatly influenced by environmental factors, the size of the wooden templates is changed along with the change of humidity and temperature, the problems of deformation, warping and the like occur in the use process, and the dimensional accuracy and the surface flatness of the concrete structure are further influenced. The steel template is a building template made of steel materials as main materials, has the characteristics of high strength, high rigidity, good dimensional stability, good reusability and the like, and can better replace a wood template to a certain extent for application in building engineering. However, in practical application, the existing steel forms still have a lot of defects, and the most obvious problem is that the existing steel forms are complex in structure, large in space required by support and too high in requirements on bearing capacity and stability of a support system. For example, chinese patent document CN111561152B discloses a concrete preparation pouring steel form, and in order to meet the requirements for supporting bearing capacity and stability, the steel form adopts a mode of clamping a side support plate, an inclined support plate and an abutting plate to support a hexagonal building support, and no relative movement occurs among the side support plate, the inclined support plate and the abutting plate, so that the supporting effect on the building support is increased. Therefore, the complexity of the formwork is increased and the cost of the mould is increased due to the additional supporting mechanisms, and a certain construction space is occupied, so that the formwork is difficult to be applied to some construction sites with limited construction space. Another chinese patent document CN111519894B discloses a steel form for concrete pouring enclosure support, which aims to solve the problems that the joint of the steel form cannot be locked into a whole when the enclosure support at the joint of the existing steel form is used, so that the steel form can incline or deflect when concrete is poured in the steel form, the stability of the steel form is poor, the joint position of the steel form can displace to a certain extent, the forming effect of the support column of the building is poor, and the like. The horizontal baffle, the longitudinal baffle, the corner plate, the supporting platform, the inclined strut and the side supporting mechanism are arranged, the corner plate is of an L-shaped structure, the corner plate is located on the outer side of the overlapping position of the horizontal baffle and the longitudinal baffle, the front side of the right end of the corner plate is connected with the upper end of the inclined strut, the lower end of the inclined strut is mounted on the supporting platform through a hinge, the supporting platform is mounted on the ground through an expansion bolt, the left end and the rear end of the corner plate are uniformly distributed with the side supporting mechanism, and the side supporting mechanism is mounted between the corner plate and the supporting platform. The steel form structure is also extremely complex and also requires a certain supporting space. In addition, the existing steel template still has the phenomena of easy mold expansion and slurry leakage, and because the steel is made of steel m
