Description

Composite steel wire rack hollow sandwich wallboard

The utility model relates to a kind of Light trabs for building.

At present, the domestic and international innovative panellised wall-steel wire net rack foam battenboard that uses, because of its lightweight, high-strength, fire prevention, protection against the tide and sound insulation, but batch production is prefabricated, and on-the-spot lapping construction is convenient to be waited good combination property and obtains extensive use.

Although its title and the trade mark are different, (as Taibai panel, leisure plate, 3D plate, the plate of comforming ...), its basic structure all is main central layer by light material, three-dimensional steel wire net rack and cement screedn constitute, the many short steel wires that pass the foam central layer are made support bar, weld mutually with steel fabric sheet at its two ends, forms the three-dimensional net rack sandwich structure, and surperficial coated is with cement screedn.The foam central layer is clamped in the steel wire net rack and plays the heat-insulation and heat-preservation effect, and steel wire net rack play fixed supporting role to central layer, and hangs cement mortar by its holder when plastering, and forms the body of wall of building.

Since fault of construction, their ubiquity some shortcomings:

Dust difficulty when 1, plaster in the scene, metope is prone to the hollowing crackle, influences workmanship.

Because foam central layer any surface finish and not absorbing water, dust difficulty when cement mortar is smeared in spray, building-site is normal a large amount of " land ash " to occur, has both caused waste of material, influences programming again, and occurs quality problems such as wall degree hollowing crackle easily.

2, wallboard manufacture energy consumption height, steel content height, cost height.

For the ease of dust, require the size of mesh opening of steel wire net rack the smaller the better, cause the pad of rack a lot, for example the pad of Taibai panel reaches 1600/m ², just wallboard manufacture efficient is low, the energy consumption height, and the unit area steel content is higher.

3, the on-the-spot required associate member kind of overlap joint of installing of wallboard is many, and consumption is big, and complex operation has improved construction costs.

Goal of the invention of the present utility model is exactly the defective that exists at above-mentioned prior art, and a kind of improvement project of proposition makes Light trabs further perfect under the situation that keeps original advantage.Change the steel fabric sheet structure, reduce the steel amount of closing, reduce the energy consumption and the cost of wallboard manufacture, simplify installation accessories kind and quantity, make prefabricated wallboard scene overlap joint is installed easily, improve work efficiency, the assurance workmanship.

Of the present utility model by following measure enforcement:

Steel fabric sheet 1 is steel wire 6, the 7 and 8 crisscross combined type net laminated structures that constitute by different-diameter, thicker wire 6 is welded into framework and fine wire 7 is welded into planar steel wire screen, with the screen cloth be combined into composite steel wire mesh sheet of finer wire 8 braiding, the end of thicker wire 6 is welded with for the steel plate piece 9 that welding usefulness is installed again.

Central layer 2 is multi-level hollow panel-type constructions, in the middle of the two-layer light weight board 10, by multi-level support bar 3 and in length and breadth spacer bar 11 form panel-type construction, the cavity of sash is an air chamber 12, the effect of air chamber is to improve protection against the tide, sound insulation, the heat-proof quality of wallboard, and can reduce the cost of wallboard.

Support bar 3 is the cross concrete members 15 by band positive stop lug boss 17; with laterally through and the steel wire 16 that clads in concrete member 15 form; steel wire 16 two ends stretch out with steel fabric sheet 1 in 6 welding of corresponding steel wire; form the three-dimensional grid structure of load; 16 protections of 15 pairs of steel wires of concrete member and booster action; simultaneously positive stop lug boss 17 is embedded in two sides light weight board 10 and 11 of parting beads in length and breadth, and its horizontal both arms stretch in the sheet material 10, not only play spacing but also play the reinforcing rib effect to plate core 2.

The external surface of the contact cement mortar of sheet material 10 spreads all over concave-convex thing 13, is the alternating expression mosaic bonding with sheet material 10 after making the cement coated, to solving the difficult and wall skin hollowing of dust fabulous effect is arranged; At the external surface of sheet material 10, also have many C type mosaic grooves 14 simultaneously, improved the intensity of wallboard corresponding to steel wire 6.

Facts have proved that technique scheme has reached the goal of the invention of expection satisfactorily.With like product relatively except that still having its total superperformance, also increased new advantage:

1, integrated cost descends significantly

Because adopt the combined type net chip architecture of thickness steel wire collocation, unit area steel wire content can descend 45%, central layer adopts the gridiron structure of hollow, and foam board saves 20%, and energy consumption reduces, and the integrated cost that body of wall is produced in batch production can reduce about 30%.

2, the central layer surface spreads all over the concave-convex thing, is convenient to inlay mortar, and the adhesive property of cement sand bed and central layer is improved, and has solved construction quality common faults such as the difficult and common wall skin hollowing of dust when plastering, crackle.

3, install firmly, the situ wet workload is little, and installation rate is fast, and expense is low.

Performances such as 4, bending resistance, resistance to compression, heat insulation, fire prevention, protection against the tide, sound insulation all are better than prior art.

Further set forth below in conjunction with drawings and Examples.

Fig. 2 is the partial sectional view of Fig. 1.

Among the figure, the 1st, clad steel silk screen sheet, the 2nd, the hollow central layer, the 3rd, support bar, the 4th, lightweight concrete screed, the 5th, the fibre reinforced cement surface layer, the 6th, the thicker wire in the steel fabric sheet, the 7th, fine wire, the 8th, fiber knitted net, fiber can be a finer wire, nylon yarn or glass fiber etc., the 9th, steel plate piece for welding, the 10th, light weight board, for example plastic foamboard etc., the 11st, be clipped in the spacer bar in length and breadth between two-layer sheet material, the 12nd, air chamber, the 13rd, the concave-convex embedding groove, the 14th, C shape mosaic groove, the 15th, the concrete member, the 16th, thicker wire, 15 and 16 form support bar 3, the 17th, the positive stop lug boss on the concrete member 15.

Embodiment:

It shows that by Fig. 2 structure makes sheet material 10 and spacer bar 11 with polystyrene foam plate, and the member 15 that concrete is prefabricated is made the central layer 2 of inner band gridiron structure.

Make framework by thicker wire 6, fine wire is made the truss bar, lays finer wire net 8 again, is welded into steel fabric sheet 1.

Two steel fabric sheets 1 are clamped in the centre from both sides with central layer, and the end of the thicker wire 16 that will stretch out and steel wire 6 welding become composite steel wire rack sandwiched plate.

Surface spraying or smear last layer concrete screed 4, the cement surface layer strengthened of coated one deck fiber again after doing.

The cross section on vertical two limits of finished product wallboard is stairstepping or ligulate.

Composite steel wire rack hollow sandwich wallboard can be made the size of 2400 * 1200 * 80mm commonly used, 3000 * 1200 * 80mm or other client needs.

Can be widely used in framework goes along with sb. to guard him the interior exterior wall surfaces of wall that exterior wall, internal partition wall, building connect layer and can directly spray various coating, paste various ornament materials such as wallpaper, mosaic and ceramic tile, result of use satisfaction, economy, society and obvious environment benefit.
