Abstract
The invention discloses a fireproof cement plate, and belongs to the field of building materials. The fireproof cement plate comprises a cement mortar outer layer and a cement mortar inner layer between which a cement cotton layer is arranged; a plurality of bulges are arranged at two sides of the cement cotton layer; the opposite sides of the cement mortar outer layer and the cement mortar inner layer are both provided with a plurality of grooves corresponding to the bulges on the cement cotton layer; the cement mortar outer layer is connected with a fireproof concrete layer. By the dual protection of the arrangement of the cement cotton layer between the cement mortar outer layer and the cement mortar inner layer and the connection of the fireproof concrete layer to the cement mortar outer layer, the fireproof and fire resistant properties of the cement plate are improved; by the clamping of the bulges on the cement cotton layer and the grooves in the cement mortar outer layer and the cement mortar inner layer, the cement cotton layer, the cement mortar outer layer and the cement mortar inner layer can be connected stably and firmly; especially when the cement plate is heated up, the structure change of the cement plate can be reduced so as to guarantee the stability.
Description
Technical field
The present invention relates to a kind of cement board, be specifically a kind of refractory cement plate, belong to building material field.
Background technology
Cement board is common constructional materials, and its easy construction, energy-conserving and environment-protective are promoted the use of widely in current building trade.In order to meet the fire prevention needs of specific buildings, at this type of constructure construction procedure usually with installing fire-proof cement plate, the extexine brushing fireprotection layer that existing fire-proof cement plate is typically employed in cement board realizes fire prevention, its flameproof effect is poor, structural stability is poor, if burning things which may cause a fire disaster can not be eliminated timely and effectively when fire occurs, the whole cement board of easy appearance falls apart phenomenon, easily causes fall injury accident.
Summary of the invention
Technical problem to be solved by this invention is to overcome prior art defect, provides a kind of fireproof performance good, well-set refractory cement plate.
In order to solve the problems of the technologies described above, refractory cement plate provided by the invention, comprise cement mortar skin and cement mortar internal layer, the cotton layer of cement is set between described cement mortar skin and cement mortar internal layer, the both sides of the cotton layer of described cement are provided with several projections, and described cement mortar opposite sides that is outer and cement mortar internal layer is equipped with several grooves corresponding with the cotton layer projection position of cement; Described cement mortar skin connects fire-resistant concrete layer.
Beneficial effect of the present invention is: (1), by arranging the cotton layer of cement between and cement mortar internal layer outer in cement mortar and being connected fire-resistant concrete layer at cement mortar skin and carrying out double protection, raising cement board fireproof performance; (2), by the projection on the cotton layer of cement engage with cement mortar skin and cement mortar internal layer upper groove, the connection between three can be made more firmly stable, particularly can reduce its structural change when cement board heat, ensure its stability.
The cotton layer of cement is rock wool, ceramic wool or resistance to guncotton and cement mortar mixture, can select, to ensure fire-resistant effect according to different needs.
The surface density of the cotton layer of cement is 160g/m
2, its fire-resistant effect is better.
The thickness of fire-resistant concrete layer is at least 1CM, arranges fire-resistant effect so more obvious.
Accompanying drawing explanation
Fig. 1 is refractory cement plated construction schematic diagram of the present invention;
In figure, the cotton layer of 1-cement mortar internal layer, 2-cement, 3-projection, 4-cement mortar skin, the fire-resistant concrete layer of 5-groove, 6-.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, refractory cement plate of the present invention comprises cement mortar internal layer 1, the cotton layer 2 of cement, cement mortar outer 4 and fire-resistant concrete layer 6.The upper surface of cement mortar internal layer 1 connects the cotton layer 2 of cement, and cotton layer 2 upper surface of cement connects cement mortar skin 4, and outer 4 upper surfaces of cement mortar connect fire-resistant concrete layer 6.
The cotton layer 2 of cement is rock wool and cement mortar mixture.The surface density of rock wool can regulate as required, and through comparing, the surface density of rock wool is 160g/m
2the fire resistance of cement board is better.
Cotton layer 2 two sides of cement are provided with several projections 3, between cement mortar internal layer 1 and cement mortar skin 4, side is in opposite directions provided with several grooves 5 corresponding with protruding 3 positions, protruding 3 snap in groove 5, the connection between three can be used more stable, thus make refractory cement plated construction more firm.
Fire-resistant concrete layer 6 is grouped into by each one-tenth of following weight portion: slag 20-30 part, bauxite 11-15 part, aluminate cement 17-23 part, flyash 15-20 part, water glass 11-15 part, silicon ash 10-16 part, melamine based water reducer 6-9 part.In order to ensure normal performance, the thickness of fire-resistant concrete layer 6 at least will ensure at more than 1CM.
The rock wool that it should be known that in above-mentioned rock wool and cement mortar mixture as those of ordinary skill in the art also can adopt ceramic wool or resistance to guncotton to substitute.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be considered as protection scope of the present invention.
