Description
Technical field
The utility model relates to building thermal insulation material, particularly a kind of large scale cracking resistance foam cement single face composite insulation boards.
Background technology
What the external wall heat insulating material for external mainly used at present is polystyrene foam plate, polyurethane foam board, polystyrene extruded sheet etc.The high insulating effect of this type organic insulation material but fireproof performance is poor, initiation fire easily, and discharge dense smoke and toxic gas in the combustion process, can cause casualties.
The foaming cement thermal insulation plate has lightweight, fire-resistant, advantages such as coefficient of thermal conductivity is low, inorganic material good endurance, is a kind of desirable building thermal insulation material.But it is big that its significant disadvantage is exactly a shrinkage factor, very easily causes body of wall appearance cracking; Secondly the water absorption rate of foaming cement thermal insulation plate is big, has reduced heat-insulating property; Moreover the mechanical strength of foaming cement thermal insulation plate is low, and is damaged easily in transportation, work progress.The method that at present the foaming cement thermal insulation plate is used for external wall outer insulation is, adopt undersized foam cement plate (250mm * 300mm) be pasted on exterior wall, foaming cement thermal insulation plate monolithic is done insulation layer or finish coat after pasting again, long in time limit, construction quality is poor.
The utility model content
The purpose of the utility model is to solve the deficiency that above-mentioned prior art exists, and provides that a kind of cracking resistance is good, good waterproof performance, high insulating effect and construction quality is high, the fast large scale cracking resistance foam cement single face composite insulation boards of speed of application.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is following: large scale cracking resistance foam cement single face composite insulation boards; It is characterized in that it comprises large-sized foam cement thin plate and the unidimensional and bonding all-in-one-piece panel with the foam cement thin plate; The foam cement thin plate is of a size of 300 ~ 600mm * 600 ~ 900mm, and thickness is 20 ~ 40mm, and dry density is 100 ~ 300 ㎏/m
- 3, its drying shrinkage value is controlled in the 0.9mm/m; Described foam cement thin plate forms polylith foam cement platelet through dividing slot; The foam cement platelet is of a size of 200 ~ 300mm * 200 ~ 450mm, divides slot wide 1 ~ 2mm, divides little 1 ~ 3 mm of depth ratio foam cement gauge of sheet of slot; Dividing the slot degree of depth is 19 ~ 39mm; Still linking to each other with the bottom that guarantees the foam cement thin plate, do not cut at the end (promptly not cutting apart fully), is to prevent that counter plate from causing damage on the one hand; Prevent on the other hand to reduce water resistance because of panel destroys.
The utility model utilizes the thin characteristic of foam cement lamella thickness, guarantees that thin plate shrinks more even along thickness direction.Though the foam cement thin plate is thinner, its heat-insulating property can satisfy the requirement of exterior wall external (or interior) thermal insulation technology of China Xia Redong cryogenic region fully.Large-sized foam cement thin plate is divided into polylith foam cement platelet, is used to reduce the shrinkage stress of foam cement thin plate, and make shrinkage stress be lower than tensile strength, prevent that the foam cement thin plate from producing shrinkage crack.
When constructing at the scene, the product of the utility model is pasted on outer (or interior) surface of external wall, thereby has formed large scale cracking resistance foam cement single face compound insulation system.Panel has waterproof action, guarantees the heat-insulating property of foam cement thin plate.
Described panel is Cement fibre panel or inferior light metal decking, and Cement fibre panel employing cement mortar and foam cement thin plate are bonding, and inferior light metal decking employing chemical bonding agent and foam cement thin plate are bonding.Have anchor hole on described foam cement platelet and the panel.
The thickness of panels such as Cement fibre panel, inferior light metal decking and the bending rigidity that modulus of elasticity will guarantee panel are enough big, and the flexural deformation that the foam cement thin plate is shunk cause is in tolerance band.
The described foam cement composite insulation boards of the utility model is packed, is transported and construct by being of a size of 300 ~ 600mm * 600 ~ 900mm, to reduce breakage, guarantees construction quality, improves construction speed simultaneously.
Adopt bondingly entirely between large-sized foam cement thin plate and the panel, can require on-site cutting to become the sheet material of different size dimensions based on the building exterior wall heat preserving structure to guarantee this composite insulation boards.
The composite insulation boards of the utility model has that cracking resistance is good, the spy of good waterproof performance, high insulating effect; During application, have construction quality height, the fast advantage of speed of application; The foam cement thin plate of large scale cracking resistance foam cement single face composite insulation boards system is thinner, but its heat-insulating property can satisfy the requirement of the exterior wall of China Xia Redong cryogenic region external (or interior) thermal insulation technology fully.
Below in conjunction with the Figure of description and the specific embodiment the utility model is described further.
