Abstract

The utility model relates to a dismantling-free prefabricated formwork shell insulation wall formwork, which belongs to the technical field of building materials. It includes a concrete formwork prefabricated in the factory. One side of the formwork is equipped with a steel wire grid insulation board, and the other side is equipped with a steel wire flat mesh. There is a concrete grid, so that the formwork on both sides forms a closed whole, and its interior is equipped with steel wires, which serve as the structural reinforcement of the concrete grid.

Description

Demolition-free prefabricated formwork insulation wall formwork

technical field

The utility model relates to a thermal insulation exterior wall formwork of a prefabricated formwork without dismantling, 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, and it is mainly suitable for applications such as 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 defects, the purpose of this utility model is to provide a prefabricated prefabricated formwork thermal insulation exterior wall template that can effectively save timber resources and labor costs, and achieve the purpose of thermal insulation and the same lifespan as the building.

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

A prefabricated formwork insulation wall formwork without disassembly, which includes a prefabricated concrete formwork, one side of the concrete formwork is provided with a steel wire grid insulation board, and the other side of the concrete formwork is provided with a steel wire flat mesh;

The surface of the prefabricated concrete formwork is evenly distributed with trapezoidal circular platforms, and concrete grids are arranged at both ends of the concrete formwork, so that one side of the concrete formwork and the other side of the concrete formwork form a closed whole. The interior is furnished with steel wires that serve as structural reinforcement for the concrete grid.

The steel wire grid insulation board on one side of the formwork plays the role of thermal insulation and waterproof and is used as a non-demolition formwork as the main body of the structure. The steel wire flat mesh inside it has been plastic-treated 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 trapezoidal circular platform on the surface of one side of the formwork is the stressed steel bar of the main body of the limiting structure to ensure the thickness of the protective layer of the stressed steel bar.

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

The concrete protection layers on both sides are not only the stress-bearing layers 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 plastering layers on both sides of the wall, eliminating the need for wall plastering and plastering construction craft.

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.
