Abstract
The utility model relates to a plaster plate, which is used as building materials. The utility model is provided with a penetrating middle hole, wherein, one side or both sides of the middle hole are provided with a sandwich layer which is composed of reed weaving nets. The utility model fundamentally eliminates harms which are generated by using glass fiber rope nets to workers' health. Because the reed weaving nets are used as the sandwich layer of the plaster plate, the bending strength of the plaster plate can be raised, and simultaneously, the manufacture cost of the plaster plate can be reduced.
Description
The utility model relates to the gypsum plank in the building material field, particularly has the gypsum lath of the interstitial hole of perforation.Specifically, the utility model relates to the gypsum plank of reed bar mesh grid as interlayer.
At present, building trade extensively adopts the constructional materials that gypsum plank is used as partition wall.For alleviating the needs of its deadweight and manufacturing process, this kind gypsum plank broad ways is arranged with the interstitial hole of some perforations, simultaneously, for preventing the gypsum plank fracture, improves its rupture strength, and this kind gypsum plank is provided with interlayer in the both sides of intermediate throughholes.Present employed interlayer all is the netting of weaving into glass cord.Glass fiber netting is the cost height not only, and glass fiber easily pollutes working environment, the plaster plate making workman works under this working environment all the year round, constantly sucks glass fiber and skin and often is subjected to being sticky with of glass fiber, healthy must suffering damage.In addition, glass fiber netting itself is soft, can not keep straight and upright under nature, and therefore the shape malleable, in the gypsum plank manufacture process, must be tightened glass fiber netting, and this has just brought technologic trouble.
The purpose of this utility model is to propose a kind of improved gypsum plank, overcomes in the gypsum plank manufacture process harm to working environment and the healthy generation of workman, reduces the manufacturing cost of gypsum plank, simplifies manufacturing process, improves work efficiency.
The utility model adopts the mesh grid of reed bar to finish above-mentioned purpose as the interlayer of gypsum plank.
According to the utility model, both sides at the gypsum plank interstitial hole, adopt the mesh grid of reed bar to replace the interlayer of glass fiber netting as gypsum plank, the mesh grid of reed bar is vertically to be split into reed rectangular, then, interlacing reticulates, and has certain rupture strength and bond strength for guaranteeing made gypsum plank, and the reed bar width of reed affair mesh grid and mesh size must correctly be selected.In addition, the length and width size of reed bar mesh grid interlayer should be respectively less than the length and width size of gypsum plank itself, and like this, interlayer wraps in the gypsum plank, and the reed bar can not stretch out from the edge of gypsum plank.Usually,, all be provided with the interlayer of this reed bar mesh grid, but if less demanding, and gypsum plank length hour, also can be only interlayer be set in a side of interstitial hole to the rupture strength of gypsum plank in the interstitial hole both sides of gypsum plank.
Discuss the utility model in detail below in conjunction with accompanying drawing, wherein:
Fig. 1 is the partial view of the reed bar mesh grid of amplification.
Fig. 2 is the viewgraph of cross-section of the utility model gypsum plank, has represented the position of reed bar mesh grid interlayer.
Fig. 3 is the vertical view of the utility model gypsum plank, and has represented along the section situation of A-A line among Fig. 2 in the mode of partial view.
With reference to Fig. 1, the mesh grid that is used as the gypsum plank interlayer forms with the braiding of reed bar.The reed wide material sources can be gathered materials on the spot, and reed are split into rectangular with common mode, and interlacing becomes netted, and the shape of mesh can be a rectangle, but select square usually.As the reed bar mesh grid of gypsum plank interlayer, the width S and the mesh size dimension L of reed bar there is certain requirement, this names a person for a particular job and is discussed in detail hereinafter.For preventing that the reed bar longitudinally or laterally is moved, can be coated with cementing agent at all or part of node place of reed bar mesh grid, perhaps use fine rule right-angled intersection bondage (shown among the figure 4,6 liang), make it to interfix, but this is optional, because as shown in the figure, and reed bar interlacing, be laminated, the result of pressing has stoped relatively moving between the reed bar to a certain extent.In addition, even if between indivedual reed bars several millimeters minute movement is arranged, also unlikely anti-folding or bond strength to gypsum plank produces very big influence, and most preferred embodiment of the present utility model is bondd or bondage at the node place at four angles of mesh grid and the some nodes place on the edge.Can prevent mutually moving between the reed bar so to a great extent, unlikelyly again make the braiding of reed bar net too loaded down with trivial details.
Gypsum plank is normally made with the mode of perfusion.Referring to Fig. 2 and Fig. 3, a side of gypsum plank is fluted 1, and opposite side has semicircular flanges 2, and in use, the groove of adjacent gypsum plank matches with tongue, forms the complete partition wall of surperficial driving fit.Be the deadweight that alleviates gypsum plank and the needs on the manufacturing process, the gypsum plank broad ways is arranged with some intermediate throughholes 3, and the interlayer 5 of reed bar mesh grid is usually placed in the both sides of through hole, shown in netted solid line among the figure.If the reed bar is long, stretch out the edge of gypsum plank, in the carrying and assembling process of gypsum plank, affect the reed bar easily to make to be on the gypsum plank edge gypsic horizon in the reed bar outside to peel off, therefore, the length and width size of reed bar mesh grid interlayer (M, N) should be less than the corresponding size of gypsum plank.Usually, the length and width size of mesh grid interlayer (M, N) is respectively less than 2-4 centimetre of gypsum plank length and width size.
In gypsum plank, reed bar mesh grid interlayer should with the gypsic horizon strong bonded, therefore, the width of reed bar and mesh size must correct be selected.The wide bond strength that can influence interlayer and gypsic horizon of reed bar width; The reed bar is narrow, and mesh grid interlayer itself lacks enough very tension force, then can influence the rupture strength of gypsum plank.Equally, the too small bond strength that also can influence interlayer and gypsic horizon of mesh is easily peeled off between interlayer and gypsic horizon, and therefore, the reed mat that does not have mesh of airtight braiding can not be as the gypsum plank interlayer; If but mesh is excessive, mesh grid interlayer itself also can lack enough very tension force, influences the rupture strength of gypsum plank like this.Among the embodiment of the present utility model, the reed bar width S of reed bar mesh grid interlayer is got the 2-6 millimeter, preferably the 3-4 millimeter; The mesh size dimension L of reed bar mesh grid interlayer gets 2-6 centimetre, preferably 3-5 centimetre.
The utlity model has significant advantage and higher economic benefit. At first, the material source of reed bar mesh grid is extensive, with low cost, compare reed bar mesh grid cost 40%-50% with glass fibre netting, secondly, owing to replaced glass fibre netting, fundamentally eliminated to the pollution of working environment with to plaster plate making workman's health hazard, simultaneously, can also simplify the manufacturing operation of plasterboard, be conducive to improve work efficiency; In addition, because the mesh grid of reed bar itself has certain very tension force, as behind the interlayer of plasterboard, improved the rupture strength of plasterboard. Failure test shows, the ultimate load when making the plasterboard fracture of interlayer with the mesh grid of reed bar is higher than the ultimate load that glass fibre netting is made the plasterboard of interlayer. Plasterboard of the present utility model can replace existing plasterboard with the glass cord net sandwich fully. Implement the utility model if produce the existing producer of plasterboard, utilize existing equipment to produce, needn't change equipment, need not equipment investment, can obtain great economic benefit.
