Abstract
The utility model discloses a prestressed composite floor made of a cement base material. The prestressed composite floor comprises a cement base body, wherein a decoration layer and a wear-resistant surface layer are arranged on the cement base body, and a moisture-proof bottom layer is arranged below the cement base body. The prestressed composite floor is characterized in that multiple layers of prestressed nets are arranged in the cement base body in parallel; mortises matched with link buckles are formed in the periphery of the cement base body; the prestressed nets are medium-alkali or alkali-free glass fibermesh fabrics; the mortises in the periphery of the cement base body are in inverted-cone double-hook shape; the link buckles are upper and lower pairs of double side wings, and sawtooth-shaped barb bite marks are arranged on the upper and lower pairs of double side wings. The prestressed composite floor can meet the requirements of mechanical properties and has the advantages of reasonable structure, convenience in flooring, long service life, environment friendliness and the like.
Description
Technical field
The utility model relates to architectural decoration material field, is a kind of cement matrix prestressing force composite floor board.
Background technology
Current composite floor substrate is all to adopt natural wood materials particle together with organic gel gel material after mix, then it is compressing to pass through high temperature.This composite floor board exists that fire prevention, protection against the tide, water resistance are poor, the shortcoming such as coefficient of thermal conductivity is relatively little, and particularly the harmful substance contents such as formaldehyde and benzene in organic gel is higher, in use harmful in process of production.Just there will not be above problem as floor base material with inorganic silicate cement material, but again because the fragility of material own is large, at the bottom of rupture strength, crooking ability is poor, the mortise on floor becomes mouthful rate lower, even if become mouthful, when mounted also can splitting.The problem that how to solve prior art is the difficult problem of this area always.
Summary of the invention
The purpose of this utility model is, solve this area and want to solve always, but a unsolved difficult problem still provides one can meet mechanical characteristic requirement, rational in infrastructure, mat formation conveniently, and long service life, the cement matrix prestressing force composite floor board of environment-friendly type.
The purpose of this utility model is realized by following technical scheme: a kind of cement matrix prestressing force composite floor board, it is characterized in that, it comprises cement matrix, on cement matrix, be provided with decorative layer and wear-resistant coat, below cement matrix, be provided with moistureproof bottom, the some layers of prestressed net that be arranged in parallel in described cement matrix, are provided with and the sunk coak that links buckle and match in the surrounding of described cement matrix.
Described prestressed net is middle alkali or alkali-free glass fibre grid cloth.
The surrounding sunk coak of described cement matrix is reverse taper double hook shape.
Described link buckle is upper and lower two pairs of double side wings, on upper and lower two pairs of double side wings, is equipped with zigzag barb bite mark.
Cement matrix prestressing force composite floor board of the present utility model is on cement matrix, to be provided with decorative layer and wear-resistant coat, below cement matrix, be provided with on the basis of structure of moistureproof bottom, the some layers of prestressed net that be arranged in parallel in cement matrix, prestressed net is middle alkali or alkali-free glass fibre grid cloth; So be only called prestressed net, middle alkali or the alkali-free glass fibre grid cloth of using in advance external force stretch-draw, after cement matrix intensity reaches design load, disconnect stretch-draw, grid cloth will apply compressive stress to cement matrix, the tensile stress producing under service load effect can be partly or entirely offset in the size of this stress and distribution, thereby make structure in service load, be unlikely to cracking, reduce the width of crack developing, and improve crack resistance and the rigidity of member, effectively utilize high this feature of cement material compressive strength, increased the application life on floor; Owing to being provided with in the surrounding of cement matrix and the sunk coak that links buckle and match, the surrounding sunk coak of cement matrix is reverse taper double hook shape, link buckle is upper and lower two pairs of double side wings, on upper and lower two pairs of double side wings, be equipped with the structure of zigzag barb bite mark, can realize three-dimensional pulling force connects, stressed even, bonding strength is high.

Fig. 3 is link cards buckle structure schematic diagram.
In figure: 1 sunk coak, 2 prestressed nets, 3 cement matrixes, 4 decorative layers, 5 wear-resistant coats, 6 moistureproof bottoms, 7 link buckles.
Detailed description of the invention
The utility model is described in further detail to utilize the drawings and specific embodiments below.
With reference to Fig. 1-3, a kind of cement matrix prestressing force composite floor board of the present utility model, comprise: cement matrix 3, on cement matrix 3, be provided with decorative layer 4 and wear-resistant coat 5, below cement matrix 3, be provided with moistureproof bottom 6, the some layers of prestressed net 2 that be arranged in parallel in cement matrix 3, are provided with and the sunk coak 1 that links buckle 7 and match in the surrounding of cement matrix 3.Prestressed net 2 is middle alkali or alkali-free glass fibre grid cloth.The surrounding sunk coak 1 of cement matrix 3 is reverse taper double hook shape.Link buckle 7 is upper and lower two pairs of double side wings, on upper and lower two pairs of double side wings, is equipped with zigzag barb bite mark.Link buckle 7 adopts plastic warp mould molding.The patterned paper of the middle alkali of prestressed net 2 or alkali-free glass fibre grid cloth, decorative layer 4, the alundum (Al2O3) of wear-resistant coat 5; The PVC of moistureproof bottom is commercially available prod.Cement matrix 3 comprises the cement mortar of making after cement, sand and water mix, and cement adopts inorganic silicic acid salt cement, and sand adopts river sand, and its proportioning is prior art.
Some layers of prestressed net 2 in cement matrix 3 are in the time that cement matrix 3 is produced, in advance at middle alkali or the alkali-free glass fibre grid cloth of mould higher slice stretch-draw 3 × 3mm or 2 × 2mm, the surrounding of middle alkali or alkali-free glass fibre grid cloth is executed respectively 200N ~ 500N pulling force and is fixed, be divided into 4 ~ 5 layers, each layer of grid cloth spacing distance is 2 ~ 3mm, inject the modified cement mortar mixing in advance, cement matrix 3 thickness of making are 10 ~ 12mm.Surrounding at cement matrix 3 is outputed respectively sunk coak 1, and sunk coak 1 is reverse taper double hook shape, and inside dimensions is greater than side dimension, as shown in Figure 1 the link when facilitating Floor Covering.Coordinating the assembled link buckle 7 of cement matrix prestressing force composite floor board is upper and lower two pairs of double side wings, on upper and lower two pairs of double side wings, be equipped with zigzag barb bite mark, fluting two-way plastic rises by plug for upper and lower two pairs of double side wings, and there is a zigzag fashion barb bite mark, can realize three-dimensional pulling force connects, make stressed more evenly, bonding strength is higher.
