Description

Polyurethane composite thermal insulation template

Technical field:

The utility model relates to a kind of building exterior wall heat preserving board technology field, specifically a kind of polyurethane composite thermal insulation template, is mainly used in insulation and the template of building concrete exterior wall.

Background technology:

At present, External Thermal Insulation Technology for External product mainly contains: polyphenyl plate, composite polyurethane plate thin plastering series of hard bubbling, polyurethane in-situ spraying smears heat preservation slurry series, smears heat preservation slurry (glue powder polyphenyl particle, perlite) series, compound heat preservation die plate series etc.Certain defect is more or less all there is in above-mentioned technical products in production, material, construction, Construction quality and safety, construction period, cycle lie etc., for thin-coat plaster series, to smear heat preservation slurry series substantially superseded, only has in-situ spraying polyurethane to smear heat preservation slurry and compound heat preservation die plate series is available.

Current polyphenyl plate, the composite polyurethane plate construction that hard bubbles are mainly outer sticky: its construction technology: exterior wall smears leveling mortar, cementing agent, warming plate (polyphenyl plate or the composite polyurethane plate that hard bubbles), mechanic anchor, polymer mortar, alkali resistant glass fibre open weave cloth.Security performance (wind suction prevention) and poor durability, the quality problems such as easily occur crack, come off, cycle lie only has 25 years, and outside finish can only do coating ornamental surface, can not furring brick.Due to employing is to the construction wearing cotton dress insulation after building, need the equipment such as scaffold, hanging basket, carry out high-altitude dangerous operation, efficiency is low, long in time limit, is subject to weather influence, owing to being all high-altitude manual work, workman's technical level, sense of responsibility all have influence on construction safety and quality, and safe mass is difficult to control, and easily causes safe mass hidden danger to engineering.

Current polyurethane in-situ spraying heat preservation construction technique is: levelling, the alkaline-resisting grid cloth of in-situ spraying polyurethane, interfacial agents, heat preservation slurry, polymer mortar.The comparatively outer subsides warming plate of security performance (wind suction prevention), waterproof and durability is good, but insulation layer thickness is difficult to control, and slurry leveling layer easily occurs the quality problems such as crack, and cycle lie only has 25 years, and outside finish can only do coating ornamental surface, can not furring brick.Adopt the construction to wearing cotton dress insulation after building equally, need the equipment such as scaffold, hanging basket, and carry out high-altitude dangerous operation, efficiency is low, long in time limit, is subject to weather influence, it is all high-altitude manual work, workman's technical level, sense of responsibility all have influence on construction safety quality, and safe mass is difficult to control, and easily causes safe mass hidden danger to engineering.

Chinese patent: the patent No.: 200920240787.3, denomination of invention: compound heat preservation die plate and concrete one-off construction outer wall heat preservation system, in actual product manufacturing process, life cycle of the product long (28 days), take a large amount of mould bases, maintenance place, owing to adopting artificial turnover panel technique, labour intensity is higher, cost of production is high, in maintenance with deposit in process yielding.In this product work progress, due to its weight large (35kg/ ㎡), be unfavorable for a dead lift, install and use, use cost is high.

Chinese patent: the patent No.: 200910229395.1, denomination of invention: compound heat preservation die plate and concrete one-off construction outer wall heat preservation system and construction technology, in practice of construction process, there is the deficiency of two aspects: one is the composite panel adopted, its fragility is large, the cracky when installing fixing and concrete construction, is not suitable for exterior sheathing; Two is that composite panel is smooth, although be provided with hole in interior plate face, be difficult to ensure that concrete can enrich hole, add the durability that bonds between compound heat preservation die plate and concrete exist whether with the uncertainty of concrete structure with the life-span, simultaneously because outer panel face is smooth, plaster to plate face and bring difficulty of construction, add the hidden danger of quality such as floated coat hollowing, crack.

Utility model content:

The purpose of this utility model is the deficiency solving above-mentioned prior art, and a kind of polyurethane composite thermal insulation template is provided, bonding mainly in the current outer haftplatte thin-coat plaster heat preservation technology of solution between insulation layer and concrete is insecure, poor durability, on-the-spot polyurethane coating is good in conjunction with firm waterproof, but coating thickness and heat preservation slurry cracking difficulty control, long in time limit, climate impact is large, the problems such as complex process, efficiency are low, construction safety difficult quality controls, exterior trim surface layer is limited.

The technical solution of the utility model is: polyurethane composite thermal insulation template, and its special character is, comprises insulation layer, inner side composite bed and outside composite bed; Alkali-resisting fiberglass mesh is established in described inner side composite bed; Establish Alkali-resisting fiberglass mesh in described outside composite bed, fixing rib in length and breadth inside it, the two one-tenth is integrated, and the surfaces externally and internally of described insulation layer adheres to inner side composite bed and outside composite bed respectively, and rib is positioned at insulation layer in length and breadth.

Compared with the prior art polyurethane composite thermal insulation exterior sheathing described in the utility model has following good effect: 1, realize building energy conservation and structure-integrated, meet building energy conservation and property indices requirement; 2, as novel wall compound heat preservation die plate, the requirement of template property indices is met; 3, life cycle of the product is short, from heavy and light (being less than 20kg/ ㎡), can reduce labour intensity, and improve work efficiency, construct more convenient, cost is lower; 4, by factorial praluction, outward appearance physical dimension is accurate, and product quality is secure, depositing, transport, unsuitable buckling deformation in work progress, ensure that plate surface evenness, verticality, plate face leveling mortar thickness can be reduced, meet the requirement of green building material-saving, environmental protection; 5, solve to the way of wearing cotton dress insulation after building from construction, reach insulation and external wall protection body same life-span, improve in composite bed production technology, structure structure, material selection etc. simultaneously, solve the production existed in current compound heat preservation die plate and concrete one-off construction outer wall heat preservation system and the defect existed in constructing.
