Description

Insulating brick

Technical field

The utility model relates to a kind of insulating brick.

Background technology

The plate brick of at present city and farm building great majority employing deadweight and hollow brick mix builds a wall with cement, perhaps build a wall with steel concrete, even cob wall is also being continued to use in some remote districts.With the body of wall that the deadweight brick is done, its heat-insulating property extreme difference increases wall weight, in order to increase its heat-insulating property, can only increase thickness of wall body or do external thermal insulation system, increases cost, has reduced the building effective area, the waste resource.

The utility model content

For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of insulating brick, and this insulating brick is from light, high, the good heat insulating of intensity.

For realizing above-mentioned target, the utility model adopts following technical scheme: a kind of insulating brick, it is characterized in that described insulating brick comprises skin and the composite cement foam inner cord that is made of hollow brick, and described insulating brick is Z-type.

Further, the aforementioned hollow brick is concrete hollow block.

Insulating brick of the present utility model has following characteristics:

(1) from heavy and light, can alleviate wall weight;

(2) intensity is high, can increase safety factor;

(3) owing to adopt the Z-shaped structure, reduce heat transfer, improved heat-insulating property;

(4) reduce cost;

(5) increased the effective area of building.

Description of drawings

Fig. 1 is the sectional drawing of insulating brick;

Fig. 2 is the schematic diagram of Z-type hollow brick.

The implication of Reference numeral among the figure:

1, insulating brick, 2, skin, 3, internal layer.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is done concrete introduction.

As shown in Figure 1, Fig. 1 has shown the sectional drawing of insulating brick.Insulating brick 1 comprises skin 2 and internal layer 3.Wherein, skin is hollow brick, and as shown in Figure 2, this hollow brick is Z-type, and internal layer 3 is the composite cement foam plate, and it is made of the composite foamed slurry of inorganic pottery sand cement.Specifically, insulating brick of the present utility model is to inject the composite foamed slurry of inorganic pottery sand cement in the Z-type hollow brick, forms behind setting and harden, and therefore, insulating brick is the Z-type structure also, thereby has reduced heat transfer, has improved heat insulation effect.

The hollow brick that adopts is A level incombustible material, and the composite foamed slurry of inorganic pottery sand cement is A level incombustible material.Wherein hollow brick is concrete hollow block.

The composite foamed slurry of inorganic pottery sand cement that adopts is by quick hardening sulphoaluminate cement, flyash, and pottery sand, hydrogen peroxide, the silicon ash, the PP fiber, hydrophober, the materials such as calcium stearate form.With cement, flyash, silicon ash are as cementitious material, and pottery sand is as cage construction, and hydrogen peroxide plays foaming effect, and the PP fiber plays the cracking resistance effect, and hydrophober improves impervious rate, and calcium stearate plays the blowing promotor effect.Dry density is 250Kg/m3-300Kg/m3 behind the slurry setting and harden, and coefficient of thermal conductivity is 0.06-0.08w/(m. k).

The composite foamed slurry of inorganic pottery sand cement accounts for 80%-90% of cumulative volume in the insulating brick, and hollow brick accounts for 10%-20% of cumulative volume.

Claims (2)

1. an insulating brick is characterized in that, described insulating brick comprises skin and the composite cement foam inner cord that is made of hollow brick, and described insulating brick is Z-type.

2. insulating brick according to claim 1 is characterized in that, described hollow brick is concrete hollow block.
