Abstract

The utility model discloses a foam concrete sandwich five-hole brick. A brick body consists of an outer wall (1) and an inner wall (2). Five sandwich cavities are defined by the outer wall and the inner wall; a large sandwich cavity (4) is arranged in the middle and the other sandwich cavities (3) are equal in size and are in central symmetry; and an inorganic heat preservation light material is added into the sandwich cavities to form a core layer. The manufacturing cost of building heat preservation can be greatly reduced due to a self-heat preservation function of the brick and the total manufacturing cost can be reduced by 30%. The foam concrete sandwich five-hole brick provided by the utility model has the advantages of low heat conduction coefficient which is less than 0.006 w/m.k and good heat preservation property. The brick provided by the utility model comprises the five sandwich cavities, and the sandwich cavity in the middle is larger with a hollow ratio of 57%. The foam concrete sandwich five-hole brick provided by the utility model has the beneficial effects of high strength and good bending resistance. The foam concrete sandwich five-hole brick provided by the utility model uses coal ash and foam concrete, which are full-inorganic materials, as a main raw material, so as to achieve the effects of fire protection and fire resistance.

Description

The sandwich five hole building blocks of foam concrete

Technical field the utility model relates to a kind of heat preservation construction material, is the sandwich five hole building blocks of a kind of foam concrete specifically.

Mostly the present insulation blocks of background technology is that periphery is a strength materials, and inside is heat insulating material, but hollow rate is not high, and improving like hollow rate influences its intensity, and the not high heat insulation effect of hollow rate is under some influence.

The purpose of summary of the invention the utility model is to provide a kind of foam concrete sandwich five hole building blocks, and it meets the requirements of simultaneously in intensity, and hollow rate is higher, improves heat insulation effect.

The technical scheme of the utility model is following:

The main body of this building block is made up of outer wall and inwall, and outer wall and inwall surround five sandwich chambeies, and a big sandwich chamber is established in the centre, and all the other four sandwich chamber equal and opposite in directions are centrosymmetric, and adds the inorganic heat preservation light material in the above-mentioned sandwich chamber and constitutes sandwich layer.

Above-mentioned outer wall and inwall are thickeied by end face to bottom surface gradually.

The above-mentioned sandwich chamber interior angle that outer wall and inwall surrounded is a fillet.

Above-mentioned inorganic heat preservation light material is foam concrete or foamed pearlite.

The advantage of the utility model is: 1, because this building block is a self-heat conserving, can significantly reduce the cost of building heat preservation.It is the structural meterials of building, is again heat insulating material, and this building block not only can replace common brick but also can replace being incubated the benzene plate, therefore, can reduce building heat preservation total cost about 30%.

2, coefficient of thermal conductivity is low, and heat insulating ability is excellent.5 sandwich chambeies of this building block, middle sandwich chamber is bigger, hollow rate 57%, sandwich layer adopts the air concrete for insulation main body, the hollow filling part of building block, and its coefficient of thermal conductivity is below 0.06w/mk.

3, intensity is high, and anti-bending strength is good.The compressive strength of this product sandwich layer is 0.15MPa, and the compressive strength of building block main body is 0.4MPa, and the entire compression strength character is good.

4, this product primary raw material is flyash and foam concrete, is the full-inorganic material, fire prevention, fire-resistant, and refractory temperature can reach more than 1000 ℃, and fire endurance surpassed 1.5 hours fire protection requirement greater than 2 hours.

Description of drawings Fig. 1 is the utility model cross-sectional view;

Fig. 2 is that the A-A of Fig. 1 is to view;

Fig. 3 is that the B-B of Fig. 1 is to view.

The specific embodiment is described further the utility model below in conjunction with accompanying drawing.

Can see this building block by Fig. 1-3; The main body of this building block is made up of outer wall 1 and inwall 2, and outer wall and inwall surround five sandwich chambeies, in the middle of bigger sandwich chamber 4 is located at; All the other four sandwich 3 chamber equal and opposite in directions are centrosymmetric, and add foam concrete in the above-mentioned sandwich chamber and constitute sandwich layer; The above-mentioned sandwich chamber interior angle that outer wall and inwall surrounded is a fillet 5; Above-mentioned outer wall and inwall are thickeied by end face to bottom surface gradually.
