Abstract
The utility model relates to a building material, in particular to a fire barrier and an isolation beam for external wall thermal insulation, which comprise an insulation board, a composite silicate insulating paste layer, a reinforcing mesh and a facing agent layer. The composite silicate insulating paste layer is coated on the periphery of the insulation board by using the insulation board as a base, the reinforcing mesh is compounded inside the composite silicate insulating paste layer, and the facing agent layer is coated outside the reinforcing mesh. Compared with the prior art, the fire barrier and the isolation beam have the advantages that the fire barrier horizontally disposed on a building external wall and the isolation beam disposed at a window can achieve effective fire prevention and isolation performances and provide the buildings with safety performance, and the barrier and the isolation beam which are not combustible can achieve the purpose of fire spread prevention, and have better insulation effect, and are substantially same with external wall insulation materials such as EPS, XPS and PU in effect.
Description
Technical field
The utility model relates to a kind of constructional materials, is used for isolation strip, isolation beams that skin has insulation and fire-proof function.
Background technology
In the prior art, the structure that skin generally adopts is: be coated with the agent of one deck facing in warming plate outside, reach insulation, function attractive in appearance.But, this external wall structure isolation features of not preventing fires.Particularly at present owing to the wilderness demand of rapid economic development, civilian construction, if the building breaking out of fire, because exterior wall is not provided with fire barrier, isolation beams, when fire took place, the intensity of a fire can be from place on fire rapid spread, and consequence is hardly imaginable.
At the problems referred to above, the Ministry of Public Security, national house and town and country construction portion have issued [2009] No. 46 files of public logical word, about printing and distributing the notice of " civilian construction outer heat preservation system and decoration of exterior wall fire prevention temporary provisions ".Clearly stipulated the combustibility of wall heat insulation material in the file, and emphasized that skin must be provided with horizontal fire barrier, window is provided with the fire prevention isolation beams.
Therefore, for passing through logical [2009] No. 46 files of word of public affairs that plan is carried out the Ministry of Public Security, national house and town and country construction portion, improve the fire prevention isolation performance of skin, change the structure of existing external-wall heat-insulation material, it is imperative making it to increase the fire prevention isolation features.
Summary of the invention
The purpose of this utility model provides a kind of exterior-wall heat insulation fire barrier, isolation beams, and the isolation strip is horizontally set on skin, at window isolation beams is set and can plays effective fire prevention isolation performance, and the security performance of building is provided.
For achieving the above object, the utility model is achieved through the following technical solutions:
Exterior-wall heat insulation fire barrier, isolation beams comprise warming plate, composite heat-insulating silicate cream layer, are base-material with the warming plate, scribble composite heat-insulating silicate cream layer around warming plate.
Described composite heat-insulating silicate cream layer inside is compounded with reinforcing mat.
Scribble facing agent layer in the reinforcing mat outside.
Described warming plate is a phenolic foam board.
Compared with prior art, the utility model has the advantages that:
The isolation strip is horizontally set on skin, isolation beams is set, can play effective fire prevention isolation performance, the security performance of building is provided at window.Isolation strip, isolation beams itself have noninflammability, thereby can reach the purpose that stops fire spreading; Also have heat insulation effect preferably simultaneously, basic identical with common external-wall heat-insulation material such as EPS, XPS, PU effect.

Fig. 2 is the sectional drawing of the utility model exterior-wall heat insulation fire barrier, isolation beams.
Among the figure: 1-facing agent layer 2-reinforcing mat 3-composite heat-insulating silicate cream layer 4-warming plate
The specific embodiment
See Fig. 1, Fig. 2, exterior-wall heat insulation fire barrier, isolation beams, the isolation strip is horizontally set on skin and plays buffer action, and isolation beams is arranged on the window exterior wall.Isolation strip, isolation beams structure are identical, comprise warming plate 4, composite heat-insulating silicate cream layer 3, reinforcing mat 2, facing agent layer 1, described warming plate 4 is a phenolic foam board, its coefficient of thermal conductivity is 0.03W/mk, wide 300-800mm, thick 30-200mm, long 500-3000mm, with warming plate 4 is base-material, around warming plate 4, scribble composite heat-insulating silicate cream layer 3, be compounded with one deck reinforcing mat 2, scribble facing agent layer 1 in reinforcing mat 2 outsides in composite heat-insulating silicate cream layer 3 inside, facing agent layer thickness is 1-2mm, is made by sandstone, cement, wood fibre.
Described composite heat-insulating silicate cream is the commercially available prod, and its constituent is sepiolite, eakleite, shepardite, perlite microballon, glass fiber, cement, and above composition mixes to scale.
The construction of exterior-wall heat insulation fire barrier, isolation beams is simple, and is identical with benzene plate, extruded sheet job practices, adopt the heat insulating material cementing agent directly be bonded in exterior surface of wall get final product interior exterior surface of wall and the exterior-wall heat insulation fire barrier structure that is combined into one.This isolation strip is horizontally set between each layer of building, plays the effect that fire prevention is isolated.
