Abstract

The utility model provides a composite foam concrete insulation board, which is characterized in that a foam concrete layer and a cement mortar layer covered and combined on the foam concrete layer form an inner layer, the surroundings and the top surface of the inner layer are packed with a layer of latticed reinforced net, and the top surface of the inner layer is covered and combined with a cement mortar layer forming an outer layer. The composite foam concrete insulation board has the beneficial effects that the latticed reinforced net is embedded and combined in the original cement mortar layer, one surface of the latticed reinforced net and the cement mortar layer are combined in one, four side faces of the latticed reinforced net are packed with one part of four side faces of the cement mortar layer and four side faces of the foam concrete layer, and a connecting structure is arranged between the foam concrete layer and the cement mortar layer, so that the foam concrete layer is firmly connected with the cement mortar layer.

Description

The foam concrete composite insulation boards

Technical field

The utility model relates to building (energy-conservation) field of materials, relates in particular to a kind of building (roofing) thermal insulation sheet material.

Background technology

Foam concrete is good heat preserving and insulating material, durable, good stability, and also in light weight, but resistance to compression and rupture strength are lower, not wear-resisting, easy of crack, and water imbibition is higher, unsuitable direct heat preserving and insulating material as roofing.Common way is on foam concrete, to do one deck cement mortar to be used to improve intensity and wear-resisting, and is attractive in appearance.

But cement sand bed and foam concrete layer are bonding insecure, are easy to break away from or cracking, cause roofing heat-insulating layer damaged, reprocess so that architectural can not large-scale popularization or use.Tracing it to its cause is that the dry density gap of cement sand bed and foam concrete layer is excessive, and the prolongation property gap of the physical property of expanding with heat and contract with cold is excessive; Be laid on the roofing process sun on daytime in summer and be exposed to the sun, the evening temperature decline and the shrinkage in winter, levels breaks away from soon, or wash cement screed cracking, influences application life and workmanship.

Summary of the invention

The utility model provides a kind of foam concrete composite insulation boards, and purpose is to solve the prior art problem, provides a kind of cement sand bed firmly to be connected with the foam concrete layer, and promptly heat-insulation and heat-preservation has high strength again--and foam concrete composite insulation boards attractive in appearance.

The utility model technical scheme that adopts of dealing with problems is:

The foam concrete composite insulation boards; It is characterized in that: the cement sand bed that covers combination on foam concrete layer and the foam concrete layer constitutes internal layer; Said internal layer around and end face be enclosed with the latticed reinforcing network of one deck, the end face of internal layer covers and is combined with one deck and constitutes outer field cement sand bed.

Said latticed reinforcing network extends the bottom surface of parcel to said internal layer.

The beneficial effect of the utility model: be equivalent in original cement sand bed, be embedded and combined latticed reinforcing network; Latticed reinforcing network surface and cement sand bed be integrated latticed reinforcing network four sides parcel cement sand beds four sides a part and foam concrete layer four sides; Between foam concrete layer and cement sand bed, set up a kind of syndeton, thereby the foam concrete layer firmly is connected with cement sand bed.

Fig. 3 is the schematic cross-section of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

The concrete manufacturing process of the utility model: pour cement mortar in frame type die 100 earlier and form cement sand bed 1; Shake floating after; Put into the latticed reinforcing network 2 of wire lath or glass fiber reticular cloth material; The bottom surface of the latticed reinforcing network 2 of wire lath or glass fiber reticular cloth material is layered on the cement sand bed 1, and four sides erect the medial surface of the frame that is pasting frame type die 100, pour cement mortar again into and form cement sand bed 3; Shake floating--behind-the mortar, pour foam concrete again into and form foam concrete layer 4 to appointed thickness.The bottom surface of the latticed reinforcing network 2 of wire lath or glass fiber reticular cloth material just is combined in cement sand bed 1 and the cement sand bed 3 like this, the side in the process of setting of cement sand bed 3 and foam concrete layer 4 also strong bonded in the side of cement sand bed 3 and foam concrete layer 4.If the length of the side of the latticed reinforcing network 2 of wire lath or glass fiber reticular cloth material is longer; The outer bottom that can be when foam concrete layer 4 does not also solidify will not fold to foam concrete layer 4 than the side of the latticed reinforcing network 2 of long wire lath or glass fiber reticular cloth material makes 2 pairs of foam concrete layers of latticed reinforcing network 4 of wire lath or glass fiber reticular cloth material form six bread with cement sand bed 3 and wraps up in, strengthen firmness more.

Process the foam concrete composite insulation boards 10 of specification at last for (300mm-600mm) * (300mm-600mm) * (30mm-200mm).The Dimensions of foam concrete composite insulation boards 10 goods: 1 square metre of area in, 20 centimetres of thickness in.Foam concrete composite insulation boards 10 goods---surface configuration: square, rectangle, or polygon.The color of cement mortar: cement true qualities or colour.There are anti-skid design or plane in cement sand bed 1 surface.

This foam concrete composite insulation boards 10 has the cement sand bed 3 that covers combination on foam concrete layer 4 and the foam concrete layer 4 and constitutes internal layers 9; Said internal layer 9 around be enclosed with the latticed reinforcing network 2 of one deck (be wire lath or glass fiber reticular cloth) with end face; The top of internal layer 9 covers and is combined with one deck and constitutes outer field cement sand bed 1, and cement sand bed 1 is combined as a whole with cement sand bed 3.The cement sand bed 3 that covers combination on 2 pairs of foam concrete layers of the latticed reinforcing network of aforesaid way wire lath or glass fiber reticular cloth material 4 and the foam concrete layer 4 forms five bread and wraps up in.The latticed reinforcing network 2 of wire lath or glass fiber reticular cloth material can extend and wraps up to the bottom surface of foam concrete layer 4 bottom surface of internal layer 9 just, wraps up in thereby the cement sand bed 3 that covers combination on 2 pairs of foam concrete layers of the latticed reinforcing network of wire lath or glass fiber reticular cloth material 4 and the foam concrete layer 4 forms six bread.

Above-mentioned cement sand bed refers to: the concrete that adds sandstone material or inserts with Portland cement or special cement as main cementitious material.

Above-mentioned foam concrete (or claiming foam cement) refers to: use Portland cement, and special cement, the main cementitious material material (also can add other inserts) of conducts such as gypsum adds water and stirs, and introduces bubble.Solidify out into is cellular, and there is the light heat insulation material in cavity the inside.

The utility model realizes that to foam concrete and cement mortar five (or six faces) wrap up, carry secretly with glass fiber reticular cloth or wire lath; Cement sand bed and foam concrete layer are closely linked together, become an integral body; Improved whole compressive strength, effectively prevented the cracking of cement sand bed and leave with the foam concrete pull-up.Greatly improve the functional performance of product.

Claims
