Abstract

The invention provides a foam concrete composite board for a fireproof isolation belt. The foam concrete composite board is composed of two foam concrete panels and a polyurethane foam sandwich, wherein sections of the two foam concrete panels are L-shaped; the two L-shaped foam concrete panels can be closed to form a mold cavity provided with a closed end, and polyurethane foam can be poured into the mold cavity to form the foam concrete composite board for the fireproof isolation belt; and the foam concrete panels are made of one of a pulverized fuel ash foam concrete sheet material, a slag foam concrete sheet material, a polystyrene granule light-weight foam concrete sheet material, an expanded perlite foam concrete sheet material and s fiber-reinforced foam concrete sheet material. The composite insulation board has the advantages of excellent fireproof performance, light weight, thermal insulation, low cost and good durability, can be produced into composite boards of different volume weights, and is applicable to the fireproof isolation belt for an external wall of a building.

Description

The foam concrete composite plate is used in a kind of fire barrier
Technical field
The invention belongs to building material field, particularly use the foam concrete composite plate in a kind of fire barrier.
Background technology
Existing insulating board for building is main with organic polyphenyl plate, and its fire line is poor, has potential safety hazard.In the practice of construction process, the fire barrier need be set, traditional fire barrier material mainly is rock wool, inorganic heat insulation mortar, gather phenol formaldehyde foam etc., these materials exist cost an arm and a leg, disadvantages such as construction technology complicacy or durability deficiency.
Utility model patent 200820104071.6 has related to a kind of polyurethane hard bubble sandwiched integral heat preservation light wall board; The polyurethane hard bubble sandwiched layer of cast one deck makes the integral heat preservation wallboard between two-layer concrete light wall panel; But when this patented product was applied to the fire barrier, the sandwich hard polyurethane foam contacted burning things which may cause a fire disaster easily and the composite plate fire line is descended.
Summary of the invention
The objective of the invention is the problem that exists to present fire barrier material, the spy develops a kind of foam concrete composite plate, and it has fire prevention, light weight, insulation, inexpensive characteristics, can be used as the external wall fire barrier.
Technical scheme of the present invention: prefabricated different unit weight (150-700kg/m 3) foamed concrete plate, fixing two sheet materials make " L " type foamed concrete plate closed mutually; Form the die cavity of end sealing; Polyurethane A, B component directly are sprayed in the die cavity after mixing, serial chemical reaction take place generate hard-foam polyurethane, composite plate is a sandwich structure.
Advantage of the present invention is: the composite plate panel is the inorganic non-combustible material, and composite plate one end adopts the foam concrete sealing, does not directly contact burning things which may cause a fire disaster, and whole fireproof performance is good; Have light weight simultaneously, insulation is with the characteristics of major structure of construction with the life-span; And easy construction, can make composite plate and the fine stickup of body of wall with cement mortar.
Description of drawings
Fig. 1 is a schematic perspective view of the present invention;
Fig. 2 is the sectional drawing of Fig. 1.
Among the figure: 1 foamed concrete plate, 2 hard-foam polyurethanes.
The specific embodiment
As shown in the figure, foam concrete composite plate of the present invention comprises that foamed concrete plate and polyurethane foam constitute, and two " L " type foamed concrete plates are panel, and sandwich is a hard-foam polyurethane.Directly be sprayed at the middle fire barrier that can make sandwich structure of two foamed concrete plates that fix after polyurethane A, B component are mixed and use the foam concrete composite plate.
Embodiment 1: foamed concrete plate unit weight is 150kg/m 3, sandwich die cavity thickness is 20mm, the composite plate general thickness is 50mm.
Embodiment 2: foamed concrete plate unit weight is 300kg/m 3, sandwich die cavity thickness is 30mm, the composite plate general thickness is 50mm.
The foregoing description is merely one of preferred embodiment of the present invention, is not to limit protection scope of the present invention with this, so: all equivalences of doing according to structure of the present invention, shape, principle change, and all should be covered by within protection scope of the present invention.

Claims (4)

1. the foam concrete composite plate is used in a fire barrier, and it is to be made up of foam concrete panel of two " L " types and polyurethane foam sandwich.
