Described high strength gypsum plate comprises 2 combined type grid ribs layers 3,2 combined type grid ribs layers 3 are set in the top layer of the close first external surface 1a in gypsum board core 1 and the top layer of close second external surface 1b respectively, and become to be symmetrical arranged between the fibrous mesh cloth 31 of two combined type grid ribs layers 3.This symmetrically arranged advantage is: the uniform intensity distribution making high strength gypsum plate; The internal stress of the high strength gypsum plate caused by production technology is evenly distributed; Make the STRESS VARIATION of being heated of high strength gypsum plate even, thus high strength gypsum plate can be extended from the time being heated to cracking, meet fiery stability and fire endurance to improve.
See the embodiment shown in Fig. 2 to Fig. 5, each combined type grid ribs layer 3 comprises 3 layers of fibrous mesh cloth 31,3 layers of fibrous mesh cloth 31 represent with 31a, 31b and 31c respectively, the interlayer of each layer fibrous mesh cloth 31 adopts adhesive structure, in other words, fibrous mesh cloth 31a, there is not braiding relation between fibrous mesh cloth 31b and fibrous mesh cloth 31c.So-called adhesive structure comprises two kinds of modes: together with a kind of fibrous mesh cloth 31a, fibrous mesh cloth 31b and fibrous mesh cloth 31c are directly set in respectively by gypsum board core 1; Another kind is bonded together by slurry.Each layer fibrous mesh cloth 31 of front a kind of mode lays setting respectively in stacked mode, and namely fibrous mesh cloth 31a, fibrous mesh cloth 31b and fibrous mesh cloth 31c are deployed to respectively in the gypsum board core 1 of ot-yet-hardened on high strength gypsum board assembly line; Each layer fibrous mesh cloth 31 of a kind of mode then lays setting in stacked mode simultaneously, namely fibrous mesh cloth 31a, fibrous mesh cloth 31b and fibrous mesh cloth 31c are first by slurry bonding one-tenth combined type grid ribs layer 3, are then deployed in the gypsum board core 1 of ot-yet-hardened by combined type grid ribs layer 3 on high strength gypsum board assembly line.No matter adopt which kind of mode, the structure laid by stacked mode, combined type grid ribs layer 3 can be formed in gypsum board core 1, and described combined type grid ribs layer 3 is set in wherein by gypsum board core 1.Obviously, this combined type grid ribs layer 3 be set in gypsum board core 1 has the booster action of built-in muscle, although it may be in the top layer of the close first external surface 1a in gypsum board core 1 or the top layer of close second external surface 1b, but solidify the structure of bonding, make combined type grid ribs layer 3 still have the booster action of very strong built-in muscle.Should understand, the multiple combined type grid ribs layers 3 be set in gypsum board core 1 are structures of a kind of built-in muscle, its be different from completely be arranged on gypsum board core with docile or other modes surface on the structure of enhancement Layer, because the structure of this set enhancement Layer on the surface of gypsum board core is if not being set in gypsum board core, then it can not have the booster action of built-in muscle.Included by each combined type grid ribs layer 3 of the embodiment that Fig. 1 to Fig. 4 provides, the number of plies of fibrous mesh cloth 31 is 3 layers, but the number of plies of fibrous mesh cloth 31 included by combined type grid ribs layer 3 of the present utility model is 3 layers and is not limited to 3 layers, but, the too much number of plies can increase processing cost, and the very few number of plies effectively can not increase density, thus, preferred number of plies scope be 2 layers to the number of plies of in 10 layers, as: the number of plies of the fibrous mesh cloth 31 included by double-layer combined grid ribs layer 3 is 2 layers, the number of plies of the fibrous mesh cloth 31 included by three-layer combined grid ribs layer 3 is 3 layers, the number of plies of the fibrous mesh cloth 31 included by four layer composite grid ribs layers 3 is 4 layers, the number of plies of the fibrous mesh cloth 31 included by ten layer composite grid ribs layers 3 is 10 layers.
The size of mesh opening of each layer fibrous mesh cloth 31 of same combined type grid ribs layer 3 is equal, distance J between adjacent two warps of i.e. each layer fibrous mesh cloth 31 of same combined type grid ribs layer 3 is equal, and the distance I between adjacent two parallels is equal, such structure is conducive to the specification of unified fibrous mesh cloth 31.The warp of each layer fibrous mesh cloth 31 in each layer fibrous mesh cloth 31 of same combined type grid ribs layer 3 staggers setting mutually, and namely the warp of each layer fibrous mesh cloth 31 is not overlapping.The parallel of each layer fibrous mesh cloth 31 in each layer fibrous mesh cloth 31 of same combined type grid ribs layer 3 staggers setting mutually, and namely the parallel of each layer fibrous mesh cloth 31 is not overlapping.Obviously, described mutually staggering is arranged so that being evenly distributed of warp, parallel.But, the warp meeting each layer fibrous mesh cloth 31 staggers setting mutually, the parallel of each layer fibrous mesh cloth 31 staggers the structure arranged mutually, can also be in the following way, size of mesh opening in each layer fibrous mesh cloth 31 of same combined type grid ribs layer 3 becomes integral multiple relation, that is: the distance J between adjacent two warps of same layer fibrous mesh cloth 31 is equal, but become integral multiple relation between the distance between adjacent two warps of different layers fibrous mesh cloth 31, as fibrous mesh cloth 31a adjacent two warps between distance be fibrous mesh cloth 31b adjacent two warps between 2 times of distance, distance I between adjacent two parallels of same layer fibrous mesh cloth 31 is equal, but become integral multiple relation between the distance between adjacent two parallels of different layers fibrous mesh cloth 31, as fibrous mesh cloth 31a adjacent two parallels between distance be fibrous mesh cloth 31b adjacent two parallels between 2 times of distance.
The fiber type of described fibrous mesh cloth 31 preferably adopts fiber filament.Every root warp comprises at least one fiber filament, and namely every root warp is the fiber bundle comprising at least one fiber filament, or the single for being pooled capital by plurality of fibers long filament.Every root parallel comprises at least one fiber filament, and namely every root parallel is the fiber bundle comprising at least one fiber filament, or the single for being pooled capital by plurality of fibers long filament.The monofilament quantity of every root root warp or parallel can set according to the requirement of strength of grid ribs layer, but because combined type grid ribs layer 3 of the present utility model have employed the structure that overlapped way is composited, so the structure of the unlike existing fibrous mesh cloth of the intensity of combined type grid ribs layer 3, only depend on the warp of single fibrous mesh cloth and the monofilament quantity of parallel and density, but obtain the warp of combined type grid ribs layer 3 and the ideal density of parallel by the number of plies increasing fibrous mesh cloth 31, therefore, the structure of combined type grid ribs layer 3 of the present utility model, make the distribution density of the warp of fibrous mesh cloth 31 or the monofilament quantity of parallel and warp or parallel, can determine according to the woven performance of the stitchability of fiber and existing fiber weaving cloth equipment, make filametntary damage in the activities of woven shaped fibers grid cloth 31 minimum, the micro-crack that the fibre caused by weaving produces is minimum, make the existing equipment of weaving cotton cloth can give play to best woven performance, to guarantee product quality and the production efficiency of fibrous mesh cloth 31.Because combined type grid ribs layer 3 of the present utility model have employed the structure that overlapped way is composited, so the warp of combined type grid ribs layer 3 and the density of parallel not exclusively depend on the warp of fibrous mesh cloth 31 and the distribution density of parallel, but depend on fibrous mesh cloth 31 number of plies, therefore, the warp of combined type grid ribs layer 3 of the present utility model and the distribution density of parallel, the restriction of the warp of fibrous mesh cloth 31 and the distribution density of parallel can not be subject to, distance j between adjacent two warps of the combined type grid ribs layer 3 be namely associated with the distribution density of combined type grid ribs the layer 3 and distance i between adjacent two parallels can arbitrarily set as required, theoretically, distance j between adjacent two warps of combined type grid ribs the layer 3 and distance i between adjacent two parallels can be zero or negative value (namely overlapping situation), and distance J between adjacent two warps of the fibrous mesh cloth 31 and distance I between adjacent two parallels cannot realize the situation of zero or negative value, on the contrary, for meeting weaving, distance between adjacent two parallels of Distance geometry between adjacent two warps of existing fibrous mesh cloth can not be less than the magnitude of tens millimeters usually.
In order to high strength gypsum plate can be produced on conventional Thistle board production line equipment, the interlayer of each layer fibrous mesh cloth 31 of same combined type grid ribs layer 3 preferably adopts slurry bonded structure, described slurry adopts the one in starch slurry or PVA class slurry, because these slurries all have the adhesive property good with gypsum board core 1, each layer fibrous mesh cloth 31 of combined type grid ribs layer 3 can be made well to be set in top layer and the centre of gypsum board core 1.Starch slurry or PVA class slurry, can adopt the formula slurry used in gypsum board manufacture or procedure of fibre production, and it has good sizing technique performance.Described fibrous mesh cloth 31 is that at least one braiding in organic fiber, inorfil and metallic fiber material forms.As can be that any one material weaves separately, or two or three mixed weaving in organic fiber, inorfil and metallic fiber.
To sum up finding, because the utility model have employed the multi-layer combined grid ribs layer 3 be set in gypsum board core 1, and each combined type grid ribs layer 3 comprises the structure of multi-layer fiber grid cloth 31, so solve prior art can not meet the mechanical strength of gypsum plank as reinforcing rib problem with single grid cloth, when using equal number fibril, the mechanical strength of combined type grid ribs layer of the present utility model can improve several times relative to the mechanical strength of traditional single grid cloth.And, or because have employed the multi-layer combined grid ribs layer 3 be set in gypsum board core 1, and each combined type grid ribs layer 3 comprises the structure of multi-layer fiber grid cloth 31, high strength gypsum plate is made to further improve fire resistance, particularly meet fiery stability and fire endurance aspect of performance in reduction temperature distortion, lifting, all can obtain obvious effect.
