Abstract

The utility model discloses a prefabricated aerated concrete assembled heat preservation composite wall, including the aerated concrete board, rock wool sandwich layer, FRP fibre net cloth and exterior trim surface course. Trough of belt of aerated concrete board to closely laminate with the rock wool through epoxy. FRP fibre net cloth is pasted to rock wool sandwich layer one side, just FRP fibre net cloth pass through polymer mortar with the rock wool sandwich layer is closely laminated. The exterior trim surface course combine together with composite board through pasting with FRP net cloth. The utility model provides a prefabricated aerated concrete assembled heat preservation composite wall board has following advantage: the reduction improves wall body thermal insulation performance go along with sb. To guard him the prerequisite of the thickness of system panel as the frame under, has higher intensity simultaneously, can satisfy the requirement that system wind load and seismic action were gone along with sb. To guard him to the high level. The present invention is suitable for commercial production.

Description

Precast aerated concrete assembled heat insulation composite wall
Technical field
The utility model relates to constructional materials design field, is specifically related to precast aerated concrete assembled heat insulation composite wall.
Background technology
China's Development of High-rise Buildings is quick, its constructional materials adopts arrangement of reinforcement aerated concrete panel mostly, but, in traditional arrangement of reinforcement aerated concrete panel, reinforcing bar is less to aerating plate the shear contribution, so traditional arrangement of reinforcement aerating plate can only rely on improve thickness to ensure the shear resistance of aerating plate, but, thickening of body of wall also brings a lot of problem, such as reduces indoor effective area, brings inconvenience etc. to construction transport.
Not high and need the mode improving its thickness based on the above-mentioned intensity due to arrangement of reinforcement aerated concrete panel, use to us and bring problems, and China is high-rise and the fast development of super highrise building, be now badly in need of a kind of lightweight, high-strength, environmental protection, energy-conservation New Building Materials.
Utility model content
Technical problem to be solved in the utility model solves traditional high-rise exterior-protecting wall panel should have the basic demand that some strength meets wind load and geological process, meet the requirement that wall thermal insulating is energy-conservation again, wallboard too thickly can not affect the inside effective area etc. of house simultaneously.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is precast aerated concrete assembled heat insulation composite wall, it is characterized in that, comprises aerated concrete panel, rock wool sandwich layer, FRP fibrous mesh cloth and exterior trim surface layer.
Described FRP gas concrete composite plate, is characterized in that, the strength grade of described aerated concrete panel core is A3.5, and severe grade is B04, is furnished with reinforcing bar, and a trough of belt.
Described rock wool sandwich layer, is characterized in that, FRP fibrous mesh cloth is pasted in described rock wool sandwich layer side, and described FRP fibrous mesh cloth is fitted tightly by polymer mortar and described rock wool sandwich layer.
Described exterior trim surface layer, is characterized in that, described exterior trim surface layer combines with composite board by pasting with FRP grid cloth.
Described FRP fibrous mesh cloth adopts fiberglass gridding cloth.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the sectional view of Fig. 1;
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, the utility model provides a kind of precast aerated concrete assembled heat insulation composite wall, comprises aerated concrete panel core 1, rock wool sandwich layer 2, FRP fibrous mesh cloth 3 and exterior trim surface layer 4.
Aerated concrete panel core 1 one side with groove 5, and is fitted tightly by epoxy resin and rock wool sandwich layer 2.FRP fibrous mesh cloth 3 is pasted in rock wool sandwich layer 2 side, and FRP fibrous mesh cloth 3 is fitted tightly by polymer mortar and rock wool sandwich layer 2.Exterior trim surface layer 4 combines with composite board by pasting with FRP grid cloth 3.
The strength grade of aerated concrete panel core 1 is A3.5, and severe grade is B04, is furnished with reinforcing bar 6, the external surface of aerated concrete panel core 1 is provided with groove 5.In order to ensure better to contact bonding by epoxy resin with rock wool sandwich layer 2.
FRP fibrous mesh cloth 3 adopts fiberglass gridding cloth, its mesh size adopts 10mm × 10mm specification, every square heavy 125g, fabric width adopts 90cm, fiberglass gridding cloth has that intensity is high, alkali resistance good, can resist the corrosion of alkaline matter lastingly, composite plate novel under equality strength condition reduces to some extent than traditional arrangement of reinforcement plate thickness, is the desirable reinforcing material of combined wall board.
Prepare the method for precast aerated concrete assembled heat insulation composite wall, as shown in Figure 1 and Figure 2, the method comprises the following steps,
Step 1: make aerated concrete panel core.
Namely make trough of belt gas concrete plate prefabricated member as aerated concrete panel core, when making aerated concrete panel, be furnished with reinforcing bar.
Step 2: make rock wool sandwich layer.
Namely adopt prefabricated rock cotton board as rock wool sandwich layer.
Step 3: aerated concrete panel core 1 and rock wool sandwich layer 2 tight bond.
Clean to aerated concrete panel core 1 and rock wool sandwich layer 2 surface clean, smear epoxy resin adhesive for building in aerated concrete panel core 1 with groove face, by aerated concrete panel core 1 and rock wool sandwich layer 2 tight bond.
Step 4: rock wool sandwich layer 2, FRP fibrous mesh cloth 3 and exterior trim surface layer 4 three tight bond.
Clean to rock wool sandwich layer 2 and exterior trim surface layer 4 surface clean, and configure polymer mortar, polymer mortar Ying Suiyong is with joining; Scrape last layer polymer mortar on rock wool sandwich layer 2 surface, scrape area should slightly larger than the length of FRP fibrous mesh cloth 3 or wide, thickness unanimously should be about 2mm; After having scraped polymer mortar, should by placed on it for FRP fibrous mesh cloth 3, the flexure plane of FRP fibrous mesh cloth 3 is towards rock wool sandwich layer, execute trowelling from mediad surrounding to put down, make in screen cloth embedded polymer thing mortar, after surface dry, execute thereon again and smear one layer of polymeric mortar, thickness 1.0mm, one layer of polymeric mortar is scraped on finish coat 4 surface outside simultaneously, and by exterior trim surface layer 4 and FRP fibrous mesh cloth 3 tight bond.
Step 5: curing molding.
Use dryer to heat overall structure, accelerate solidifying of epoxy resin and polymer mortar, combining closely between guarantee combined wall board each several part.
Precast aerated concrete assembled heat insulation composite wall has the following advantages:
1) the utility model adopts FRP fibrous mesh cloth to replace traditional arrangement of reinforcement, decreases the thickness as framework retaining design sheet material;
2) the utility model adopts rock wool sandwich layer, improves wall insulation performance;
3) precast aerated concrete assembled heat insulation composite wall described in the utility model has higher intensity, can meet the requirement of high-rise retaining design wind load and geological process.
4) the utility model preparation technology is simple, does not need a large amount of skilled labors, thus greatly reduces cost of labor and fabrication cycle, is applicable to suitability for industrialized production.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or close technical scheme with the utility model, all falls within protection domain of the present utility model.
