Description

A kind of high-strength light composite board

The materials for wall of present architectural use, major part are " Qin brick and Han tiles " that has continued two thousand years.And it is played the light sound-insulation thermal insulation plate of substitution effect, mainly contain following several: TZH lightweight model, gypsum composite board, papery honeycomb composite plate, kinds such as steel wire net rack sandwiched plate and fibre reinforced cement hollowcore slab.It below is simple commentary to its pluses and minuses.

1, the compound model of TZH lightweight: this model is to be aggregate with Superlight ceramsites, pearl rock sand and cement, and it is reinforcing material that two faces add the peace glass fabric, and operation processing and fabricatings such as above moulding/demoulding form.The about 5CM of thickness of slab after the moulding, mass area ratio is every square metre of 40KG approximately.In practical application, because its flexural strength is poor, cause easily to fracture, and range of application is also more single, can only be applied to interior wall and cut off.

2, gypsum composite board: be to make skeleton with plaster strip formula lightgage steel joist, fill full acoustical and thermal material as mineral wool, glass wool and so in the skeleton gap, surface layer is composited with Thistle board or fiber reinforced gypsum board.This composite plate has tolerant noise-insulating warm-keeping and fireproof performance preferably, but water resistance is poor, weight per unit area big, function of use is more single, can only be used on the indoor partition.

3, in existing honeycomb panel sheet material, the laminboard layer honeycomb has aluminium matter honeycomb, papery honeycomb, frp honeycomb.Aluminium matter honeycomb and frp honeycomb generally only are applied on the aluminium alloys exterior wall cladding because it costs an arm and a leg and the processing technology difficulty.Behind the compound upper layer material of papery honeycomb, be mainly used on inner partition plate, door leaf, furred ceiling and the furniture.Its shortcoming of the sheet material that the papery honeycomb is combined into is that fireproof performance is poor, meets the high temperature carbonization of catching fire easily, meets water or makes moist softening easily and fall end intensity, is difficult for filling the tolerant noise-insulating warm-keeping material in the skeleton grid, and preventing destructing performance is poor.

4, steel wire net rack sandwiched plate: be to do core, do skeleton with the steel wire stringer for two, pass core and two facial bone framves weld, repave cement bonded sand oar surface layer and form with connector with foamed plastics or rock wool.Its weight per unit area is about 4KG/M before the sand oar that do not lay cement ²About.But its shortcoming be after will installing just bedding cement bonded sand oar and also complete the cement bonded sand oar after its weight be increased to 90KG/M ²About.

5, fibre reinforced cement hollowcore slab: be the inner partition plate of using often at present, it is to make with alkali resistant glass fiber cloth and cement etc., belongs to the inorganic wallboard of the hydraulicity.On the inner longitudinal direction of central layer, equidistantly have circular hole or square hole to alleviate panel weight.Percent opening on the longitudinal cross-section is about 28%～58.5% of sectional area.Its shortcoming is that weight per unit area is heavier, about 35.5KG/M ²～60KG/M ²Between, and intensity is also lower.

The purpose of this utility model is to provide a kind of high-strength light composite board.

The utility model by core skeleton, core fill out core material, surface layer constitutes, the core skeleton is spliced by the steel band of zigzag undulating shape, core is filled out in the space that core material is filled in the core skeleton, more compound upper layer around core.

Core is the functional material of acoustical and thermal, simultaneously its core skeleton that constitutes with thin steel band and surface material compound well after, form between two surface layers and support, be equivalent to numerous structural I-beam, make sheet material have extraordinary mechanical property by numerous regular hexagon honeycomb lattice.Compare with existing Light trabs, at identical sheet metal thickness, identical surface material and fill out under the condition of core material, have better resistance to compression, rupture strength, and range of application is also more extensive.

1, weight per unit area light specific gravity: with wide with 75MM.0.15MM the core skeleton that thick cold-rolled strip is made is an example, if inserts is selected self-extinguishment polystyrene foamed plastics for use, the core weight per unit area after making is at 4.5KG/M ²Below, adding two compound different surface materials, its weight per unit area is all light than existing Light trabs.

2, the resistance to compression of sheet material, rupture strength are higher.Because the compound good back of honeycomb skeleton and surface material forms the surface layer plate by numerous i beam braced structures, make sheet material that good mechanical property be arranged, form by the steel band structure owing to the honeycomb skeleton simultaneously, make it that good toughness and elasticity be arranged, aspect shockproof and the protecting against shock destruction superior performance is being arranged.

3, fill out core material and select variation: foamed plastics, heat insulating and sound insulating light materials such as cement expanded perlite, cement and expanded vermiculite, rock wool, glass wool all can be used to do the core material of filling out of sheet material core, and are more extensive to the selection of filling out core material than existing light weight board.

4, the selection of surface material can variation: since the core skeleton on filling various fill out core material after, the central layer dihedron has become very smooth face: can paste upward different surface layer plate of different surface materials or cast according to the difference of function of use.

5, the range of application of sheet material is more extensive: the honeycomb skeleton with cold-rolled strip is made can adapt to different needs according to different function of use fillings upward different inserts and compound different surface layer plate.It both can be used as frame construction inside and outside wallboard, building add a layer wall interior panel, door leaf etc., also be simultaneously the ideal material in one off houses, combination reassembling type house.

6, easier for installation quick: compare with existing Light trabs, because its weight per unit area is lighter relatively, convenient carrying and installation in work progress.Its installation effectiveness is more than ten times of masonry walls, has not only alleviated labour intensity and has improved efficiency, also can reduce random watt of the brickbat that is difficult to clear up simultaneously, and is quite favourable to civilized construction.
