Description

A kind of without cold bridge assembled composite thermal-insulation external wall panel

Technical field

This utility model relates to building board technical field, is specifically related to a kind of without cold bridge assembled composite heat preserving external wall Plate.

Background technology

In recent years, China advocates architectural industrialization, spread assembled arthitecutral structure energetically, wherein assembles with steel construction Formula building system is one of Main System.Steel construction assembled architecture, is with shaped steel, light steel as structure, be prefabricated in the factory Novel light sheet material is the building gone along with sb. to guard him, and can realize component, component prefabrication, at the scene assembling construction.The speed that builds a house is fast, joint About floor space, scene does not has or few wet trade, does not pollute and rubbish, the development trend of building after being.

Tradition can be used for the sheet material of partition wall, has hollow stripe board, EPS cement composite board (two-sided composite calcium silicate plate) two kinds Main material.Hollow profile board cost is low, the fluting that cannot punch, bulk strength are poor；EPS cement composite board cost is high, good integrity, Can be punched fluting.Both the above sheet material is generally used for interior wall partition, thickeies EPS cement composite board and can be used for exterior wall.

There is a common disadvantage in above sheet material, it is simply that material thermal conductivity is the highest, and when using as exterior wall, outside is necessary Do heat-insulation layer construction again, have a large amount of wet trade, with fabricated construction objective contradiction, therefore can not meet exterior wall assemblingization requirement.

In recent years having the bar shaped sheet material of another kind of composite heat-insulating layer, with EPS as core, hexahedro parcel foam cement is formed compound Sheet material, bonding for strengthen between two-sided foam cement, reserve some holes in core plane, foam cement is in core thickness side Post, two sides foam cement before and after pulling is connected to being formed.This sheet material has tenon mouth (male and female groove) about plate width direction, in order to adjacent Two boards splices not crack.Because there being heat-insulation layer, this sheet material can be used as exterior wall, but after installing, the foam cement of stitching portion, thickness If the dry cement in degree direction connects post is the formation of the cold bridge inside and outside body of wall.The formation of cold bridge, can at indoor/outdoor temperature-difference relatively Time big, plate surface can form condensation, destroys decorative layer, even causes and come off.This have the plate construction of cold bridge, piece side Formula, makes this sheet material be difficult to promote, is not suitable for assembling type buildings, it would be highly desirable to improve.
