Description

A kind of novel high-strength heat preserving high-sound insulation high combined wall board

Technical field

The utility model belongs to constructional materials, is mainly used in the sound insulation of building partition thermal insulation, is a kind of novel high-strength heat preserving high-sound insulation high combined wall board.

Background technology

China is carrying out walling reform and building energy conservation at present, and four municipalities directly under the Central Government and provincial capital with good conditionsi require to reach the standard of building energy conservation 65%.Along with the deep development of China's walling innovation with building energy conservation, and people are to the raising of dwelling environment comfort level requirement, to the raising day by day of buildings exterior-protected structure thermal insulation and energy-conservation requirement, both at home and abroad circummure protection structure and material property inside and outside the building are all paid much attention to and developed very fast.Many new external-wall heat-insulation materials and combined wall board have appearred.The external-wall heat-insulation material that generally uses is at present pasted polyphenyl plate (EPS) and extruded sheet (XPS) as the skin surfaces externally and internally, its coefficient of thermal conductivity is lower, can reach 0.04w/ (mk) but poor with the metope bonding force, easily playing drum comes off, the job practices complexity, the cost height, maximum shortcoming is not prevent fires, disaster hidden-trouble is very big, and China's highrise building breaking out of fire in 2007 to 2008 is 990 more than according to statistics.Occurred polyurethane heat insulation material afterwards, and though added fire retardant, belonged to organic combustible material together, and can not thoroughly solve the problem that the building fire prevention is not fired, still more complicated, particularly price are wanted 200 to 500 yuan for high 1 square metre with the building sticking construction.Have and make on the building that combined wall board is directly installed on frame construction, to inject steel form moulding be wallboard as polyphenyl plate fritter bar and cement mortar are mixed, this wallboard after after a while since polyphenyl plate for the organic material cement mortar be inorganic material both can not be firm bonding, produce and separate, wallboard is destroyed.And polyphenyl plate is an organic material, in case breaking out of fire, the toxic gas that the polyphenyl plate burning produces can make the people suffocate in one minute even be dead.Also having a kind of combined wall board outside of cement foaming material is thin-walled concrete duricrust, cement foamed heat insulating material is equipped with in the inside, cement foamed heat insulating material is that inorganic material can not burnt, even breaking out of fire can not produce toxic gas yet; thin-walled concrete shell and cement foamed heat insulating material are all the mutual adhesive property of cement-based material and well can produce and separate; cement foamed heat insulating material good heat insulating; but intensity is limited; shell strengthens with concrete; this composite plate is heavier, transportation, installation process labor strength are bigger.Also having a kind of combined wall board in addition, is to pour into granular polystyrene and cement mortar mixture in the middle of doing shell with calcium silicate board, insulation and soundproof effect are preferably arranged, but granular polystyrene belongs to organic material, still has disaster hidden-trouble.In sum: scientific and reasonable, economic, construction simply reaches the standard of building energy conservation 65%, uses the method for paste heat-preserving plate and make light lath for building partition wall with above-mentioned heat insulating material all not ideal.

The utility model content

The purpose of this utility model is to resolve the defective that light lath for building partition wall exists, satisfy the standard-required of building energy conservation 65%, provide a kind of compactness good, intensity is good, good heat insulating, light weight, surface density meets the industry new standard, soundproof effect is good, and it is little to do shrinkage value, the novel high-strength heat preserving high-sound insulation high combined wall board that fire prevention is not fired.

To achieve these goals, the technical solution adopted in the utility model is: a kind of novel high-strength heat preserving high-sound insulation high combined wall board, it is characterized in that doing shell body by foaming concrete inorganic heat insulation plate and calcium silicate board forms, described foaming concrete inorganic heat insulation plate is clipped in the hard shell body that is made of calcium silicate board and concrete.

The inorganic heat insulation plate that foaming is good is in advance put into punching block, and clamp with calcium silicate board top and bottom, bonding with cement mortar between calcium silicate board and the foaming concrete inorganic heat insulation plate.Leave a fixed gap apart from the punching block limit all around, with mortar or fine-stone concrete, this novel high-strength heat preserving high-sound insulation high combined wall board of pour-shapings such as haydite concrete.Can be according to the difference in China area, as: the Xia Redong cryogenic region, severe cold and cold district can be made different-thickness, its intensity must satisfy the requirement of strength of wallboard, the heat insulating material of interior folder is divided by cement, and flyash is the main outer also high heat insulating material of available other good heat insulating of foaming concrete inorganic heat insulation plate.Shell concrete part can be joined fine steel rib or steel fabric sheet, and fiberglass gridding cloth is made a kind of combined wall board of high strength heat preserving high-sound insulation high like this.

Compare with existing various light lath for building partition wall, the utlity model has following advantage:

1. the thin-wall shell made from calcium silicate board can guarantee the intensity that wallboard is required.In light weight, surface density is far below industry standard.

2. accompany light heat insulation materials such as foaming concrete inorganic heat insulation plate in the calcium silicate board hard shell body, have the intensity height, good heat insulating.
