Abstract

The utility model relates to a light sandwich partition wall plate which is made from inorganic cementitious materials. The utility model is characterized in that a joining hole 4 is arranged at the light filling material layer of the middle of the utility model, the inner part of the joining hole 4 is filled with the cementitious material 4a (keel), and the cementitious material 4a is combined with cementitious material plates 1, 3 to form an integrative structure; thus, the utility model has the advantages of light specific gravity, high intensity, water resistance, fire prevention, thermal insulation, sound absorption, cheap price and beautiful appearance. The utility model is the most ideal partition wall plate of the building.

Description

Light sandwich plate

The utility model relates to a kind of lightweight made from cement inorganic material and cuts off wallboard.

Similar partition wallboard in the prior art, having a kind of is to use metallic framework, wherein accompanies foamed plastics such as polyamine fat, polyethylene, reaches the lightweight partition wallboard that house Co., Ltd produces as Beijing hundred million profits, though its intensity height, it costs an arm and a leg, uses inconvenience (mud is smeared at the scene of need).The low-cost light internal wall dividing plate that has deep blue Nan County, Hebei Tie Dong magnesite product factory to produce, its structure are to be bonded with yellow plate paper etc. between the two-layer cementitious materials as filling spine material, but its proportion is bigger, and intensity is not high, complex process.Retrieve at the problems referred to above, do not find the technical solution relevant as yet with the present invention.

The purpose of this utility model is exactly to solve the shortcoming that exists in the prior art, thus design a kind ofly promptly take into account price, make light specific gravity, intensity height, technology simply cut off wallboard again.

The purpose of this utility model is achieved in that

Form sandwich dividing plate by plate and one deck lightweight filler that two-layer cement inorganic material is made, be provided with connection holes in the lightweight filler, irritating in the hole has above-mentioned cement inorganic material to form keel, two agglutination material flitch are combined as a whole, in order to increase the intensity of dividing plate, on the agglutination material flitch, be shaped on the reinforcement convex tendon.

Described cement inorganic material mainly contains various cement, gypsum, magnesia and composition thereof etc.; Described light filler mainly contains polyurethane foamed plastic, polyethylene foams, wooden saw foam etc.; Described reinforcement convex tendon promptly can be located on the face that touches with the light filler knot, also can be located on the external surface.About connection holes, its shape and distributed quantity can determine that key is the bulk strength that promptly will guarantee plate, makes it in light weight again according to concrete needs, and the technician that this point is general can accomplish well.

Owing to adopted technique scheme, make that the reduction of the utility model price, proportion reduce, intensity increases, good integrity, fire prevention, waterproof, thermal insulation, sound absorption qualities all belong to superior, and have excellent decoration, are to cut off the Wall plate at present ideal building light-weight.It can also be as the sheet material of objects such as prefabricated house, door-plate, workbench, beat insulating sound insulating board.

For the utility model is described better, following routine accompanying drawing provides a most preferred embodiment of the present utility model.

Description of drawings:

Fig. 1 is a profile stereogram of the present utility model;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 has the dividing plate generalized section of strengthening convex tendon.

As shown in Figure 1, the flat board made from cement or magnesia 1, accompany the light filler layer made from polyethylene foams 2 between 3, it also can be made into and dull and stereotyped 1, the plate of 3 identical sizes, its plane is provided with connection holes 4, as dotted line among Fig. 1 is represented, its distribution can be an ancient unit of weight cloth, cementitious materials pours in the connection holes with dull and stereotyped 1,3 joining situations as shown in Figure 2, promptly pave the plate slurry during fabrication earlier and form dull and stereotyped 3, put light filler layer 2, bonding with its flat board 3, then slip is poured into from connection holes, layer stone slurry forms flat board 1 thereon at last, like this flat board 1, the 3 keel 4a that formed by the slip in the connection holes 4 link up.In order to gain in strength, can be provided with along the dividing plate length direction and to strengthen convex tendon 5, as shown in Figure 3.

Claims (2)

1, a kind of lightweight sandwich panel, it is characterized in that plate and one deck light filler that it is made by two-layer cement inorganic material form, light filler is provided with connection holes, pours into above-mentioned cementitious materials in the hole and forms keel, two agglutination material flitch are combined as a whole, and light filler is clipped in the middle.

2, filled board according to claim 1 is characterized in that being shaped on the agglutination material flitch reinforcement convex tendon.
