Description

Prefabricated reinforced truss wall formwork

technical field

The utility model relates to a prefabricated reinforcement truss wall formwork, 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.

Contents of the invention

In order to overcome the above defects, the purpose of this utility model is to provide a prefabricated steel truss wall formwork that can effectively save timber resources and labor costs.

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

A prefabricated reinforced truss wall formwork, which includes concrete formwork on both sides of the load-bearing wall, and a steel bar flat mesh is arranged in the concrete formwork on both sides as structural reinforcement for the load-bearing wall and the concrete formwork;

The steel bar flat mesh on both sides is welded and connected by obliquely inserted steel bars to form a steel bar truss, and the steel bar flat mesh is bent out of the concrete formwork at both ends of the formwork;

One side of the concrete formwork is attached with an insulation board, and the outer side of the insulation board is attached with a concrete protective layer;

The concrete formwork, the insulation board body and the concrete protective layer are connected as a whole through the steel wire grid, and bayonets are provided at both ends of the concrete formwork. Bayonet for easy splicing.

The obliquely inserted reinforcement is "triangular" or "X".

The obliquely inserted connecting steel bar can be "triangular" or "X-shaped", in order to ensure that the formwork on both sides does not move relative to each other.

The wall formwork is a part of the load-bearing wall. When the wall is poured, it must bear the lateral pressure generated when the structural concrete is poured.

The thermal insulation board body is a building material with thermal insulation function, which may be an organic thermal insulation material or an inorganic thermal insulation material.

The beneficial effects of the utility model:

1. The utility model realizes free form support, form removal, and free of painting;

2. The utility model reduces fire hazards;

3. The utility model has the functions of heat preservation, waterproof, sound insulation, anti-crack and anti-seismic structure;

4. The utility model can reduce the consumption of traditional wooden templates;

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

detailed description

The utility model is described in detail below in conjunction with accompanying drawing:

A prefabricated reinforced truss wall formwork, which includes concrete formwork 1 on both sides of the load-bearing wall, and the concrete formwork 1 on both sides is provided with a steel bar flat mesh 2 as structural reinforcement for the load-bearing wall and the concrete formwork 1;

The reinforcement flat meshes 2 on both sides are welded and connected by oblique insertion of the reinforcement bars 3 to form a reinforcement truss.

One side of the concrete formwork 1 is attached with an insulation board body 4, and the outer side of the insulation board body 4 is attached with a concrete protective layer 5;

Concrete formwork 1, insulation board body 4 and concrete protective layer 5 are connected as a whole through steel wire grid 6, and bayonet 7 is provided at both ends of concrete formwork 1.

The obliquely inserted reinforcing bar 3 is a "triangular" or "X" type.
