Description

Grooved non-detachable steel wire grid insulation formwork

technical field

The utility model relates to a thermal insulation formwork of a grooved non-dismantling steel wire net frame, which belongs to the field of building materials.

Background technique

At present, the reinforced concrete structure construction technology commonly used in my country's construction industry has a large amount of wood used, and the high loss of formwork cannot be recycled; while the current traditional external wall insulation technology has cumbersome procedures, and the strength of Taibo board and Shuleshe board is not enough. Various disadvantages of insufficient adhesion.

Contents of the invention

In order to overcome the above-mentioned defects, the purpose of this utility model is to provide a steel wire grid insulation formwork with grooves, which can effectively save wood resources and labor costs, and achieve the purpose of heat preservation and the same life span of buildings

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

A thermal insulation formwork with grooves for a non-dismantling steel wire grid, which includes a thermal insulation board with grooves, a plurality of grooves evenly distributed on its surface, rough surface of the thermal insulation board, and evenly dense bumps on both sides of the surface, to strengthen the thermal insulation board and concrete Excellent adhesion, and has the function of sound insulation and sound absorption. There are splicing buckles around the insulation board;

Steel wire mesh sheets are arranged on both sides of the insulation board, and the outer steel wire mesh sheet and the inner steel wire mesh sheet form a network frame by obliquely inserting connecting ribs.

The shape of the groove is trapezoidal or square.

The acute angle formed by the obliquely inserted connecting ribs ranges from 45° to 90°; the obliquely inserted connecting ribs are distributed in a figure-of-eight shape, or in an X-shaped distribution.

The obliquely inserted connecting bars of the utility model can limit the movement of the insulation board and ensure the thickness of the concrete protective layer on the outer side of the insulation board; the outer steel wire mesh sheet of the utility model is also used as the structural steel bar of the concrete outer protective layer.

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 sheets on both sides are used as the structural reinforcement of the outer concrete protective layer to effectively restrain the deformation of the outer concrete protective layer.

The grooves on the insulation board are to reserve welding space for the steel wire grid, so that the steel wire grid can be welded close to the surface of the insulation board, further reducing the thickness of the insulation wall.

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.

Beneficial effects of the utility model:

1. The utility model realizes the use of the insulation board as a formwork without dismantling;

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 make the thickness of the thermal insulation wall only equivalent to 50% of the traditional wall.

Detailed ways

The following structural drawings 1, 2, and 3 describe the utility model in detail:

A self-removable thermal insulation formwork with grooves, which includes a thermal insulation board 1 with grooves, a plurality of grooves 4 are evenly distributed on the surface, the surface of the thermal insulation board 1 is rough, and bumps 5 are uniformly densely distributed on both sides of the surface, and the reinforced thermal insulation board and The cohesion of concrete, and has the function of sound insulation and sound absorption. Splicing buckles are arranged around the insulation board 1 . Steel wire mesh sheets 2 are arranged on both sides of the insulation board, and the outer steel wire mesh sheet and the inner steel wire mesh sheet form a stable grid frame by obliquely inserting connecting ribs 3 . The oblique insertion of the connecting rib 3 of the utility model can limit the movement of the insulation board 1 and ensure the thickness of the outer concrete protective layer of the insulation board 1; the outer steel wire mesh sheet 2 of the utility model is simultaneously used as a structural steel bar for the outer concrete protection layer.
