Description

A fireproof insulation formwork

technical field

The utility model relates to a fireproof and heat preservation formwork, in particular to a fireproof and heat preservation formwork used for heat preservation of cast-in-place concrete beams, columns, shear walls and floors, and belongs to the technical field of energy-saving building materials.

Background technique

The traditional method of building exterior wall insulation often has quality defects and problems such as hollowing, cracking, and falling off during actual use. In order to fundamentally solve the quality defects and problems of external wall insulation, self-insulation of building components is a general trend and is also guided by national policies. The filling part can be solved by self-insulation masonry. There are cold and heat bridge problems in the beams, columns and shear walls of the building, which can only be completed by external wall insulation and self-insulation pouring; the best solution is to use self-insulation Insulation free formwork.

In China, there are also some patents and literature introductions on the self-insulation-free formwork, and there are also some engineering practices. The main structure has two directions: one is that the organic thermal insulation material composite material is the thermal insulation core material. The thermal conductivity of the material is small, and the thermal insulation effect is good; the main disadvantage is that the thermal insulation material has a low fire rating. stress, and prevent cracking of the plastering layer; these measures have increased the difficulty of production of the thermal insulation formwork, increased the mass per unit area of the thermal insulation formwork, and increased the difficulty of installation. The second is that the inorganic rock and mineral wool fiber slats are used as the insulation core material. The outer side of the insulation material is grooved and embedded with reinforcing ribs to resist bending. The inner and outer sides are plastered with composite reinforced mesh mortar to protect the insulation material. The weight per unit area is heavy, the strength is low, the water resistance is poor, and the cohesion is small. The outer plastering layer is easy to crack due to the obvious difference in thickness and stress.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model provides a fire-proof and heat-preservation template with good cohesion, high strength, light weight and uniform thickness of the outer plastering layer.

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

A fire-proof and heat-preserving template, which is provided with a first outer alkali-resistant glass fiber mesh cloth, an outer polymer mortar layer, a second outer alkali-resistant glass fiber mesh cloth, and silicon non-combustible composite expansion according to the use state from outside to inside. Polystyrene foam insulation board, inner alkali-resistant glass fiber mesh cloth, inner polymer mortar layer.

In order to ensure the rigidity of the product, the mesh spacing of the alkali-resistant glass fiber mesh cloth is 4-8 mm, and the mass per unit area is 130-350 g/m ² .

In order to ensure heat preservation and product strength, the thickness of the silicon non-combustible composite expanded polystyrene foam insulation board is 30-150 mm, and the thickness of the polymer mortar layer is 3-8 mm.

In order to ensure the bulk density and strength requirements, the bulk density of the silicon non-combustible composite expanded polystyrene foam insulation board is 160-250 kg per cubic meter, and the compressive strength is greater than 0.15 MPa.

Preferably, the specifications of the fireproof and thermal insulation formwork are 1200mm-3000mm in length and 300mm-1200mm in width.

Compared with the prior art, the utility model has the following advantages:

1. The insulation core material of the fireproof insulation template is A-grade material. Compared with the common organic foam insulation board: the fire protection level is high, and it is not necessary to increase the thickness of the inorganic insulation layer and the thickness of the polymer mortar layer to meet the fire protection requirements, which is beneficial Reduce the quality per unit area of the template.

2. There is no need for prefabricated ribs to increase the rigidity of the product, and the structure is simple and easy for large-scale production in factories; the reinforced protective layer reinforced with alkali-resistant glass fiber mesh cloth has a uniform thickness and is not easy to crack.

3. Compared with the rock wool core self-insulation template: the silicon non-combustible composite expanded polystyrene foam insulation board has strong integrity, high strength, good cohesion, water resistance and weather resistance, and the template structure is simple, suitable for large-scale production and application.

The fireproof and thermal insulation formwork of the invention can be used for thermal insulation and fireproofing of concrete beams, columns and shear walls.
