A plastic foam cement composite insulation board and its production and construction method

Abstract

The invention provides a plastic foam cement composite insulation plate directly laid on a building level surface, as well as a manufacture and construction method thereof. The plastic foam cement composite insulation plate comprises a plastic foam insulation bottom die and a bearing concrete structure which is poured on the plastic foam insulation bottom die, wherein a plurality of grooves which are staggered one another are formed in the upper surface of the plastic foam insulation bottom die; vertical ducts are formed in the joints of the plurality of staggered grooves and lead to the lower surface of the plastic foam insulation bottom die; and the diameters of the lower end parts of the vertical ducts are increased; and the bearing concrete structure comprises legs which are poured in the vertical ducts, ribs poured in the grooves and a surface layer poured on the upper surface of the plastic foam insulation bottom die. The plastic foam cement composite insulation plate is a novel construction material with waterproof and heat-insulation double functions, and has the advantages of light weight, good waterproof and heat-insulation effect, simple operation, low cost, low labor consumptionand the like.

Description

technical field [0001] The invention relates to the technical field of new building materials, in particular to a plastic foam cement composite thermal insulation board for direct laying on the building level and its production and construction methods. Background technique [0002] The floor level of the building (especially the top floor) has many functional requirements, such as waterproof, heat preservation and heat insulation, and the structure should be simple, easy to construct, light in weight, low in cost, etc. There are many structures, each with its own emphasis. For example, for surface waterproofing, the commonly used waterproofing materials are various kinds of waterproofing membranes, waterproofing coatings, waterproofing cement, etc. Waterproof membranes are generally hot construction, mostly baked by fire, the main disadvantage is that the bonding is not comprehensive, there are seams, and some special parts, such as corners, nozzles, etc. Not easy to repa...

AI Technical Summary

Problems solved by technology

Its shortcomings are that the strength is not high, the self-protection is not strong, and the anti-cracking effect is poor.

But whether it is a waterproof membrane or a waterproof coating, it can only function in waterproofing, and it cannot show its advantages in terms of heat insulation.
