Abstract
The utility model relates to a new external thermal insulating wall. A thermal insulating layer (2), a protective layer (3), and a decorative facing layer (4) are orderly arranged on the outer side of a wall basal layer (1) from inner to outer. A building thermal insulating anchor bolt (6) embedded inside the protective layer (3) penetrates the protective layer (3) and the thermal insulating layer (2) to be fixedly connected with the wall basal layer (1). The thermal insulating layer (2) is a polyurethane horniness foam plastic which is generated by the in-situ reaction of the high activity polyether polyatomic alcohol modified from low molecule polyatomic alcohol and isocyanate with higher-NCO content. The protective layer (3) is composed of a netted sheet material (5) which is pressed and embedded between two anti-crack mortar layers, and the anti-crack mortar of the anti-crack mortar layers is composed of polymer emulsion or glue powder, cement, sand, polypropylene fibers, and other accessory materials. The decorative facing layer (4) is paint or a face brick. The new external thermal insulating wall has a few hierarchy structure, good integrality, and good external thermal insulation.
Description
Technical field
The utility model relates to a kind of external heat insulating wall of new generation, is specially adapted to the building of Xia Redong cryogenic region.
Background technology
The waterproof of building and insulation are two big hot issues of builing industry.Traditional constructional materials performance is single, is difficult to take into account water resistance and heat-insulating property.In recent years Yan Zhi a kind of polyurethane heat insulating wall, it is to make insulation layer with polyurethane rigid foam plastic, particularly the polyurethane rigid foam plastic of in-situ spraying can seal the hole of body of wall basic unit, has improved water resistance, has good thermal insulation property again.But based on the body of wall basic unit of inorganic material and polyurethane rigid foam plastic based on organic material, poor adhesive force, surface layer is easy to crack, during especially for the wall face, the polyurethane rigid foam plastic planeness of in-situ spraying is difficult to control, thus the adhesive power and the quality of influence outside finish coat.For addressing the above problem, the someone adopts in body of wall basic unit and applies polyurethane primer, or applies the interfacial agents layer, with the combine firmness of raising polyurethane rigid foam plastic with body of wall basic unit; In addition,, smear polymers anti-cracking mortar again and be pressed into alkali resistant glass fibre open weave cloth,, certain effect is also arranged preventing cracking though solved insulation layer planeness problem at the polyurethane rigid foam plastic external surface increase leveling layer of spraying.But the wall body structure level is too much, and it is loaded down with trivial details to construct, and cost is improved.
Summary of the invention
The purpose of this utility model is to provide a kind of external heat insulating wall of new generation, and is simple in structure, easy construction, and good integrity, waterproof thermal-insulated effective.
Realize the technical scheme of the object of the invention: a kind of external heat insulating wall of new generation, the outside in body of wall basic unit has insulation layer, topping and finish coat from inside to outside successively, is embedded in the building heat preservation crab-bolt in the topping, run through topping and insulation layer, basic unit fixedlys connected with body of wall; Described insulation layer is the polyether polyol with high activity by the low molecular polylol modification, the polyurethane rigid foam plastic that generates with the higher isocyanates real-world effectiveness of-NCO content; Described topping is to press the mesh sheets of burying to constitute by two-layer anticracking grout interlayer, and its anticracking grout is made up of polymer emulsion or rubber powder, cement, sand, polypropylene fibre and other auxiliary material; Described finish coat is coating or face brick.
In the above-mentioned external heat insulating wall, the coating that constitutes described finish coat is weather-proof elastomeric propylene acids exterior wall coating material; The face brick that constitutes described finish coat is of a size of 95 * 45 * 7mm.So more help overcoming problems such as the finish coat that causes because of variation of ambient temperature is out of shape, ftractures, comes off.
In the above-mentioned external heat insulating wall, the mesh sheets that constitutes topping is braid or wire lath sheet.
In the above-mentioned external heat insulating wall, the surface finish of body of wall basic unit is ± 5mm and drying more to help the formation and the adhesive fastness of insulation layer.
The body of wall basic unit of above-mentioned external heat insulating wall is reinforced concrete wall, solid brick body of wall, hollow brick wall or air-entrained concrete building block body of wall.
Technique effect of the present utility model: the external heat insulating wall of adopting technical solutions of the utility model has following advantage: 1. owing to be polyether polyol with high activity with the low molecular polylol modification as the polyurethane rigid foam plastic of insulation layer, generate with-NCO content higher isocyanates real-world effectiveness, formed foamed plastics, its abscess is fine and closely woven evenly, bond firmly with body of wall basic unit, need not in body of wall basic unit, to apply polyurethane primer or interfacial agents earlier as articulamentum, so reduced the layer of structure of external heat insulating wall, construction is simple; 2. contain an amount of polymer emulsion or rubber powder, cement, sand, polypropylene fibre etc. as the anticracking grout of topping, has coupling bridge formation function, need not to smear the coupling screed, just insulation layer and finish coat can be connected as a single entity, the mesh sheets that constitutes topping simultaneously becomes globality and the crack resistance that its skeleton has improved topping; 3. the building heat preservation crab-bolt has the mechanical anchor effect, because it is buried by anticracking grout, not only thoroughly stop heat bridge phenomenon, and avoided phenomenons such as each interlayer cracks, shelling, hollowing, further guaranteed the globality and the outer heat insulating effect of the utility model external heat insulating wall.
Description of drawings
Fig. 1 is the structural representation of the utility model external heat insulating wall.
The specific embodiment
External heat insulating wall of the present utility model, the outside in body of wall basic unit 1 has insulation layer 2, topping 3 and finish coat 4 from inside to outside successively, is embedded in the building heat preservation crab-bolt 6 in the topping 3, runs through topping 3 and insulation layer 2, fixedlys connected with body of wall basic unit 1; Described insulation layer 2 is the polyether polyol with high activity by the low molecular polylol modification, the polyurethane rigid foam plastic that generates with the higher isocyanates real-world effectiveness of-NCO content; Described topping 3 is to press the mesh sheets 5 of burying to constitute by two-layer anticracking grout interlayer, and its anticracking grout is made up of polymer emulsion or rubber powder, cement, sand, polypropylene fibre and other auxiliary material; Described finish coat 4 is coating or face brick.
