Description

A steel grid reinforced rock wool composite thermal insulation formwork

technical field

The utility model relates to the field of building materials, in particular to a steel grid frame reinforced rock wool composite thermal insulation template.

Background technique

With the implementation of building energy-saving policies and building fire protection codes, the rapid development of wall insulation materials has been promoted. The cast-in-place concrete composite thermal insulation formwork has been widely used in my country because of its simple construction process and the same lifespan as the building. Polyurethane rigid foam board, polystyrene foam board, phenolic plastic foam board and other organic insulation materials have been widely used in building insulation templates because of their excellent thermal insulation performance, but organic insulation materials are flammable. Materials, which have the possibility of causing fire, often cannot meet the requirements of the current fire protection codes for building design. Insulation materials such as expanded perlite insulation board, foamed cement insulation board, and inorganic material-wrapped polystyrene particle insulation board can meet the requirements of Class A non-combustible material standards for combustion performance classification, and have also been applied in building insulation templates, but due to their The thermal insulation performance is poor, and often cannot meet the requirements of the current building design thermal insulation performance. Therefore, the preparation of building thermal insulation formwork with good thermal insulation performance and Class A fire protection is a technical problem that needs to be solved urgently.

Contents of the invention

Aiming at the deficiencies of the prior art, the utility model provides a steel grid frame reinforced rock wool composite thermal insulation template, which not only meets the requirements of the current national standard for thermal insulation and fire prevention, but also has high structural strength and is easy to manufacture.

The utility model is realized through the following technical scheme. It provides a steel grid frame reinforced rock wool composite thermal insulation formwork, which includes an upper grid frame, a middle grid frame and a lower grid frame fixedly connected together, and an upper grid frame and a middle grid grid. The rock wool board between the frames, one side of the rock wool board is provided with an outer mortar protective layer that consolidates the middle grid frame and the lower grid frame together, and the other side is provided with an inner mortar layer that consolidates the upper grid frame together. Mortar protective layer.

This scheme uses rock wool board as heat insulation material, which has high heat insulation performance and belongs to A-class fireproof and heat preservation material. The grid frame of each layer is fixed with the rock wool board through the inner mortar protective layer and the outer mortar protective layer. , forming an overall thermal insulation formwork, by setting the middle grid, the lower grid is in the middle of the outer mortar protection layer, and the rock wool board is located in the middle of the thermal insulation formwork, which ensures the strength of the structure, and by setting the middle and lower grids , greatly reducing the difficulty of production.

Preferably, an S-shaped steel wire welded to the middle grid is provided between the upper grid and the lower grid, and the arc top of the S-shaped steel wire is welded to the upper grid. This preferred scheme utilizes S-shaped steel wires to securely connect the upper, middle and lower three-layer network frames into one, and welds the arc tops of the S-shaped steel wires to the upper-layer network frame, which has high structural strength and is convenient for welding construction.

Preferably, the distance between the middle grid and the lower grid is 3-8mm. The distance setting of this preferred solution not only ensures that the lower network frame is in the middle of the outer mortar protection layer, but also avoids the influence of the installation due to the excessive weight of the outer mortar protection layer.

Preferably, the rock wool board is placed on the middle grid, and the distance between the rock wool board and the upper grid is 3-8mm. The middle grid is used to support the rock wool board, which avoids the displacement of the rock wool board when forming the inner mortar protective layer. There is a gap of 3~8mm between the rock wool board and the upper grid, so that the upper grid is in the inner mortar The middle part of the protective layer, so that the connection between the upper network frame, the rock wool board and the inner mortar protective layer is more firm.

The beneficial effects of the utility model are: using the rock wool board as the thermal insulation material, the thermal insulation and fireproof performance grades are high, the rock wool board and each network frame are firmly connected as one through the inner mortar protective layer and the outer mortar protective layer, and by setting The middle grid makes the lower grid in the middle of the outer mortar protection layer, and the rock wool board is located in the middle of the thermal insulation formwork, which ensures the strength of the structure, and by setting the middle and lower grids, the manufacturing difficulty is greatly reduced.

Detailed ways

In order to clearly illustrate the technical features of the solution, the solution will be described below through specific implementation modes.

As shown in Figure 1, a steel grid reinforced rock wool composite thermal insulation formwork includes an upper grid 3, a middle grid 7 and a lower grid 8 fixed in one, and a grid between the upper grid 3 and the middle grid 7. Between the rock wool board 4, the distance between the middle grid 7 and the lower grid 8 is 8mm, and the S-shaped steel wire 5 welded with the middle grid is arranged between the upper grid 3 and the lower grid 8, and the S The arc top of profile steel wire 5 is welded with upper grid frame 3 .

Two S-shaped steel wires are arranged on each thermal insulation formwork, which are respectively located in the middle of the formwork and at one end. Rock wool boards are arranged on both sides of the middle S-shaped steel wires. Put several rock wool boards together and form the interior with mortar. 1. When installing the outer mortar protective layer, there are S-shaped steel wires on both sides of each rock wool board to limit the position and prevent it from moving.

The rock wool board 4 is placed on the middle grid frame 7, and the distance between the rock wool board 4 and the upper grid frame 3 is 8 mm, and the middle grid frame 7, the lower grid frame 8 and the mortar The outer mortar protection layer 6 consolidated together is provided with the inner mortar protection layer 1 which consolidates the upper network frame 3 and the mortar together on the other side.

When the thermal insulation formwork of the utility model is installed, the upper grid frame is opposite to the precast wall, and due to the penetrability of the rock wool board, it can be fixed with penetrating bolts, which is very fast and convenient. This thermal insulation template uses rock wool board as heat insulation material, which has high thermal insulation and fireproof performance. By forming the inner and outer mortar protective layers, each layer of grid frame and rock wool board are fixed as a whole to form an overall thermal insulation template. By setting the middle layer The net frame makes the lower net frame in the middle of the outer mortar protective layer, which ensures the strength of the structure, and greatly reduces the difficulty of production by setting the middle and lower net frames.
