Framework for in-situ casting, preparation method and wall body made of framework

Abstract

The invention belongs to the technical field of frameworks for in-situ casting, preparation methods of the frameworks, and buildings made of the frameworks, and discloses a framework for in-situ casting, a preparation method and a wall body made of the framework. The framework is characterized by comprising a first film shell located on the outermost side, and a first keel comprising at least twoparallel sticky planes is arranged on the inner side face of the first film shell; a second keel comprising at least two parallel sticky planes is arranged on the inner side of a heat-insulating board, and a second film shell is arranged on the inner side of the second keel; an inner pull rod and an outer pull rod which are mutually connected are arranged between the first film shell and the second film shell; fixed bases are arranged on the positions close to the lower portions of the outer sides of the first film shell and the second film shell, and a first supporting frame is arranged on the outer side face of the first film shell; and a second supporting frame is arranged on the inner side face of the second film shell. After supporting is completed, only direct casting is needed, machining and mounting are convenient, a large number of templates are saved, and the construction cost is greatly reduced; and after forming, the working procedures of wall plastering and concrete curingare omitted, the cost is saved, and production of building waste is reduced.

Description

Technical field [0001] The invention belongs to the technical field of a cast-in-place framework, a preparation method thereof and a building made of the framework, and in particular relates to a cast-in-place framework, a preparation method and a wall made of the framework. Background technique [0002] At present, the construction of cast-in-place frames and construction projects in China adopts the formwork system to support the cast-in-place. The use of the above-mentioned casting methods has the following defects: First, more materials and accessories are used, including all-steel molds, steel-wood molds, and multi-layer boards. Molds, plastic films, aluminum alloy molds, etc., and accessories such as tension bolts, etc. According to the actual situation of the project before the construction period, the materials used are complicated, the quantity is huge, the material consumption is large, the capital investment is large, and the cost is high; second, the construction proce...

[0002] At present, the construction of cast-in-place frames and construction projects in our country adopts the formwork system to support cast-in-place. The above-mentioned pouring method has the following defects: First, there are many materials and accessories, such as all-steel formwork, steel-wood formwork, and multi-layer wood formwork. mold, plastic film, aluminum alloy mold, etc., and accessories include pull bolts, etc., before the construction period, according to the actual situation of the project, the materials used are complicated, the quantity is huge, the material consumption is large, the capital investment is large, and the cost is high; second, the construction process is complicated , the construction process increases, resulting in a large investment in human resources, high labor intensity, slow construction period, and high labor costs

Because concrete leakage is difficult to be effectively maintained in the natural environment, the strength of concrete is difficult to guarantee, and it is labor-intensive; third, most of the traditional external wall insulation is connected to the wall by sticking nails, and the surface is 3-6mm Thick mortar protective layer. Practice has proved that due to the influence of wind, sun, rain and other natural environments, the thermal insulation layer and protective layer in this technology generally crack and fall off in a short period of time, which affects the thermal insulation effect. and the service life, the insulation layer is mostly made of polystyrene board, which is a flammable material. During the construction period, the exposed
