Description

Demolition-free precast concrete frame column formwork

technical field

The utility model relates to a demolition-free prefabricated concrete frame column template, which belongs to the field of building materials.

Background technique

The number of construction projects in our country is constantly increasing. This is mainly to provide residents with a more comfortable living environment. In the case of construction, wood formwork is one of the necessary accessories, which mainly plays a role in the construction of buildings. to a certain fixation.

Wooden formwork has been used as a building formwork for a long time. It is mainly suitable for top formwork, wall formwork, beam and column formwork, balcony formwork, and super-bright clear-faced concrete formwork without mat patterns for various high-rise buildings.

At present, the wood formwork commonly used in my country's construction industry has the disadvantages of using a large amount of wood and not being environmentally friendly.

Utility model content

In order to overcome the above-mentioned defects, the purpose of this utility model is to provide a prefabricated concrete frame column formwork without dismantling, which can effectively save timber resources and labor costs.

In order to achieve the above object, the utility model adopts the following technical solutions:

A demolition-free prefabricated concrete frame column formwork, which includes a surrounding concrete protective layer, the upper and lower ends of the concrete protective layer are provided with bayonets, the interior of the concrete protective layer is equipped with a steel wire flat mesh, and several meshes are evenly distributed on one side of the surface. Trapezoidal round platform.

The steel wire mesh sheet inside the concrete protective layer is used as the structural reinforcement of the outer concrete protective layer, which effectively restrains the deformation of the outer concrete protective layer.

The enclosed concrete protective layer not only bears the lateral pressure generated when the main body of the structure is poured for the stressed layer of the prefabricated formwork, but also can be used as the plastering layer on both sides of the wall, eliminating the construction process of plastering and plastering the wall .

The bayonet joints at the upper and lower ends of the concrete protective layer are convenient for the splicing of each unit.

The beneficial effects of the utility model:

1. The utility model realizes free from mold removal and painting;

2. The utility model reduces fire hazards;

3. The utility model can reduce the amount of traditional wooden formwork, and make the structural floor have the function of heat preservation.

4. The utility model realizes factory production, which is convenient and fast, and greatly shortens the construction time.
