Description

Demolition-free precast concrete thermal insulation frame column formwork

technical field

The utility model relates to a demolition-free prefabricated concrete thermal insulation 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.

Contents of the invention

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

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

A demolition-free prefabricated concrete thermal insulation frame column formwork, which includes a thermal insulation board body, a concrete protective layer on the outside of the thermal insulation board body, the thermal insulation board body and the outer concrete protective layer are connected through a steel wire grid, and the three are bonded to form a whole ;

The two ends of the outer concrete protective layer are equipped with bayonet joints, and the outer concrete protective layer and the "U-shaped" concrete protective layer are connected through the bayonet joints to form a prefabricated outer frame formwork for the frame column. The "U-shaped" concrete protective layer is equipped with a steel wire flat Net, one side of the surface evenly distributed several trapezoidal circular frustums.

The thermal insulation board is placed between the steel wire mesh sheets on both sides to play the role of thermal insulation and waterproof, and is used as a non-demolition formwork for the main body of the structure.

The steel wire mesh sheet inside the outer concrete protective layer is used as the structural reinforcement of the outer concrete protective layer, which can effectively restrain the deformation of the outer concrete protective layer, and has been plasticized to play the role of heat insulation.

The unevenness on the insulation board is to strengthen the bonding force between the concrete and the insulation formwork.

The two ends of the obliquely inserted connecting ribs are welded together with the steel wire mesh, which increases the integrity of the steel wire mesh frame and effectively limits the movement of the insulation board.

The outer concrete protective layer and the "U-shaped" concrete protective layer are not only the stressed layer of the prefabricated formwork, but also bear the lateral pressure generated when the main body of the structure is poured, and can also be used as the whitewash layer on both sides of the wall, eliminating the need for wall Plastering, whitewashing construction process.

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 insulation layer of the utility model is isolated from the outside world, which ensures the durability of the insulation material;

4. The utility model has the functions of heat preservation, fire prevention, weather resistance, waterproof, sound insulation, crack resistance, and structure shock resistance.

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

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