Abstract

The utility model relates to a cement slab, which is characterized in that inwards concave press lines and outwards convex press lines are uniformly distributed on the front of the slab, the press lines are square, circular, trapezoidal, triangular, etc., the back of the slab is provided with irregular concave-convex press lines, and the press lines of the utility model can be better bonded with facing materials together, the press lines can enhance the contact areas, the friction force, and bonding strength of the slab and the facing materials. When the utility model is used on a more moisture-conditioned area, the concave-convex press lines on the slab can make the facing materials on the slab easily fixed and not easily slid so as to enhance decoration quality and reach the purpose of a beautiful appearance.

Description

A kind of fibre reinforced cement flat board

The utility model relates to a kind of fibre reinforced cement flat board for building (hereinafter to be referred as cement board), particularly a kind of cement board that is used to fit up body of wall.

Now, the inside of building is modified with the outside cement board body of wall that uses, and adopts stickups such as ceramics, flag, to reach effect attractive in appearance more, this method of attaching must be earlier with surperficial plaster, stick with glue agent then ceramics or flag are fixed, but in the place of humidity, particularly bathroom, basement etc., the sticking strength of this kind ceramics, flag is lower, because surfacing is easily skidded, be difficult for fixing, thereby influence decoration quality.

The purpose of this utility model provides a kind of sticking strength height, the cement board that adhesion stress is strong, be difficult for skidding.

Cement board described in the utility model, its front is evenly distributed with and inwardly concaves or to the embossing of outer lug, dull and stereotyped reverse side is irregular concavo-convex embossing, positive embossing be lower than platen surface inwardly concave or to outer lug criss-cross or triangle or garden shape etc., dull and stereotyped density is greater than 1250 kilograms/meter ³

Adopt said structure, because dull and stereotyped density is bigger, its front has and is evenly distributed, inwardly concaves or to the criss-cross embossing of outer lug, when flat board contacts with the plaster face, the criss-cross embossing can increase friction dull and stereotyped and ceramics, flag, also increases bond area simultaneously, improves adhesion strength, make dull and stereotyped and the finish material bonding, thereby reach firm purpose.The utility model is especially moist local, and because of humidity is bigger, concavo-convex embossing on the flat board and finish material are more fixing, and bond together preferably, and the utility model is the cement board that a kind of suitable body of wall is modified.

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 is a front of the present utility model boss structure schematic diagram;

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

Fig. 3 is the structure sectional view of another embodiment of the utility model.

As shown in Figure 1 and Figure 2: there is the criss-cross embossing 2 that is evenly distributed in the front of the utility model flat board 1, and embossing 2 is to be lower than dull and stereotyped 1 plate face and to inwardly concave criss-cross, and dull and stereotyped 1 reverse side is irregular concavo-convex embossing 3.

As shown in Figure 3, the front of the utility model flat board 1 is evenly distributed with and is higher than the plate face and to the criss-cross embossing 2 of outer lug, dull and stereotyped 1 reverse side is irregular concavo-convex embossing 3.

The embossing in dull and stereotyped 1 front can be garden shape, trapezoidal, triangle, the polygon bodily form etc.Dull and stereotyped 1 density is 1250 kilograms/meter ³

Claims
