Abstract
The utility model discloses a light insulating fireproof sandwich wall slab, which belongs to building materials. Two flat grids of the utility model are symmetrical in a longitudinal direction; every two corresponding vertical wires are respectively welded with the grid center points of the flat grids by W-shaped reinforcing bars; the salient points of every two adjacent reinforcing bars, which are staggered with each other, are welded with the flat grids; a sandwich layer is an integral insulating asbestos board. The utility model has the advantages that the structure is reasonable, the utility model is convenient for construction, the utility model has a fireproof function, and the cost is low.
Description
The utility model relates to a kind of light heat insulation fire prevention sandwich wall board, belongs to constructional materials, is applicable to the interior exterior wall of non-bearing of highrise building.
At present, the existing light wall board that used of China's building trade, but do not possess the insulated fire function, Chinese patent 92204172.5 discloses a kind of Light trabs, and the connecting steel wire of its sine wave shape is given prominence to gauze wire cloth, the surface is difficult for plastering, interlayer filling foamed plastics or foaming magnesia lath, not only globality is poor, easy anti-halogen or cause the wall skin to come off, and fireproof performance is bad, the cost height.
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of light heat insulation fire prevention sandwich wall board is provided, and is rational in infrastructure, is convenient to construction, and overall performance is good, insulated fire.
The purpose of this utility model is achieved in that two flat graticule mesh symmetry up and down, and the reinforcing rib by W shape between the vertical hair of per two correspondences is welded as a whole, and interlayer is whole heat-preservation cotton plate.
Compared with prior art, advantage of the present utility model is:
1, the break of W shape reinforcing rib does not exceed flat graticule mesh, is convenient to spraying or plasters easy construction;
2, interlayer is the cotton plate of integral heat insulation, the good integrity of wallboard, insulated fire, low price.
The explanation of accompanying drawing drawing:
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with drawings and Examples in detail the utility model is described in detail:
Two flat graticule mesh (1) are symmetry up and down, reinforcing rib (2) by W shape between the vertical hair of per two correspondences (5) is welded as a whole, interlayer (3) is whole heat-preservation cotton plate, each break (4) of W shape reinforcing rib (2) respectively with the grid of flat graticule mesh (1) in spot welding, and the break (4) of whenever adjacent two reinforcing ribs (2) interlaces, with flat graticule mesh welding, leave the gap between interlayer (3) and two flat graticule mesh (1).
Softening point of the present utility model is 900-1000 ℃, and the normal temperature coefficient of thermal conductivity is 0.0321W/m, and the insulation rate reaches more than 95%, and sound insulation can not burnt under 750 ℃ of conditions greater than 40 decibels.
Claims (3)
1, a kind of light heat insulation fire prevention sandwich wall board comprises flat graticule mesh, reinforcing rib and interlayer, it is characterized in that flat graticule mesh is two symmetries up and down, and the reinforcing rib by W shape between the vertical hair of per two correspondences is welded as a whole, and interlayer is whole heat-preservation cotton plate.
2, light heat insulation according to claim 1 fire prevention sandwich wall board, each break that it is characterized in that reinforcing rib respectively with the grid of flat graticule mesh in spot welding connect, the break of every adjacent two reinforcing ribs interlaces, with flat graticule mesh welding.
3, light heat insulation fire prevention sandwich wall board according to claim 1 is characterized in that leaving the gap between interlayer and two flat graticule mesh.
