The beneficial effects of the utility model are：
(1) a kind of prefabricated combined wall board of the utility model, by using light quality, the better foam coagulation of heat-insulating property
Soil replaces a part of conventional concrete, so as to reducing the dosage of concrete so that new prefabricated combined wall board dead weight is small, protects
Warm nature can be good, and compared to traditional precast concrete wall panel, reduces production cost.
(2) a kind of prefabricated combined wall board of the utility model, exterior wall are directly laid with using ceramic tile, need not alien invasion later stage dress
Processing is repaiied, the concrete surface of interior wall is bright and clean smooth, and the later stage can not reprocess and directly use, and due to the utility model
The lighter weight of combined wall board so that lifting is more convenient, and anti-seismic performance is good, and construction and installation are simple, saves the time, and then can
Efficiency is improved in terms of production and construction two, reduces cost.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, including concrete 1, reinforcing bar is provided in concrete 1 for a kind of prefabricated combined wall board of the utility model
Mesh sheet 2,1 lower surface of concrete are connected with foam concrete 4 by fiberglass gridding cloth 3, and 4 lower surface of foam concrete passes through
Crack resist at mortar 5 is connected with ceramic tile 6.
The setting of fiberglass gridding cloth 3 can effectively prevent concrete 1 and crack with foam concrete 4, and crack resist at mortar 5 is arranged on
It can effectively prevent ceramic tile 6 between foam concrete 4 and ceramic tile 6 and foam concrete 4 crack, ceramic tile 6 is avoided to come off.
Wherein, the compression strength of concrete 1 is more than 60MPa, and bending strength is more than 6MPa, and tensile strength is more than 2MPa, stream
Dynamic degree is not less than 240mm.
Concrete 1 is used as self-compacting concrete, and compression strength, bending strength, tensile strength and mobility are above-mentioned
In the range of, the physical property that can cause the combined wall board of the utility model is more preferable, intensity higher.
Gap between concrete 1 and reinforced mesh 2 is not less than 10mm.
Gap between concrete 1 and reinforced mesh 2 is too small, and concrete 1 vibrates leakiness, there are gap, to concrete 1
Intensity damage it is larger.
The thickness of foam concrete 4 is 80mm~120mm, density 200kg/m3~400kg/m3, to ensure that this practicality is new
The heat transfer coefficient of the prefabricated combined wall board of type is in 0.1~0.6W/ (m2K within the scope of).
The thermal conductivity factor of foam concrete 4 is 0.0563W/ (m2·K)。
The thickness of crack resist at mortar 5 is not more than 5mm.
The thickness of crack resist at mortar 5 is excessive, intensity can be caused to decline rapidly, ultimately results in effect of anti-cracking decline.
A kind of production method of prefabricated combined wall board of the utility model is as follows：
Step 1：Punching block platform, formwork are cleaned, and tile mold, the porcelain that will be impregnated in advance are placed in punching block platform upper surface
Piece 6 is put into tile mold, is then uniformly paved crack resist at mortar 5, and thickness is no more than 5mm；
Step 2：Foam concrete 4 is processed into suitably sized, be positioned on crack resist at mortar 5, and by glass fibre
Grid cloth 3 is positioned over above foam concrete 4；
Step 3：Reinforced mesh 2 is positioned over by support on fiberglass gridding cloth 3, while pre-buried lifting embedded part,
Then casting concrete 1 is sufficiently vibrated；
Step 4：Receipts surface treatment is carried out to the surface of concrete 1 so that 1 any surface finish of concrete is smooth；
Step 5, form removal, prefabricated combined wall board complete, as shown in Figure 1.
The wall face of the prefabricated combined wall board prepared through above-mentioned steps is as shown in Figure 2.
The quality of the unit wall of the prefabricated combined wall board of the utility model is 300kg/m2~400kg/m2, heat transfer coefficient
In 0.1W/ (m2K)~0.2W/ (m2K), the unit wall quality compared to traditional sandwich wallboard is 550kg/m2~
600kg/m2, heat transfer coefficient is 0.28W/ (m2K)~0.29W/ (m2K), the quality of unit wall and heat transfer coefficient are all big
It is big to reduce so that the prefabricated combined wall board quality of the utility model is more preferably light, and heat insulation effect is more preferably.
By the above-mentioned means, a kind of prefabricated combined wall board of the utility model, by using light quality, heat-insulating property is more preferable
Foam concrete replace a part of conventional concrete, so as to reduce the dosage of concrete so that new prefabricated composite wall
Small, the good heat insulating of plate dead weight, and exterior wall is directly laid with using ceramic tile, and the processing of alien invasion later stage finishing is not required, interior wall mixes
Solidifying soil any surface finish is smooth, and the later stage can be used directly, and the manufacture craft of the combined wall board of the utility model is simple, quality compared with
Gently so that lifting is more convenient, and anti-seismic performance is good, and construction and installation are simple, saves the time, and then can be from production and construction two
Aspect improves efficiency, reduces cost.
