Abstract
The utility model relates to a concrete structure, in particular to a fiber reinforcement multi-layer cement plate. The fiber reinforcement multi-layer cement plate comprises a cement pressing plate and reinforcement fiber grid cloth. The reinforcement fiber grid cloth is adhered between layers of the cement pressing plate. The cement pressing plate has 2-3 layers, and the reinforcement fiber grid cloth has 1-2 layers. The fiber reinforcement multi-layer cement plate combines common advantages of the cement pressing plate and the reinforcement fiber grid cloth, has high tensile strength and pressive strength and good bending resistance and shock resistance, and the fiber grid cloth can effectively prevent cracks in the cement pressing plate from being caused and developing. Under a large impact load effect, the reinforcement fiber grid cloth can dissipate impact energy to a large degree and improve the shock resistance of the fiber reinforcement multi-layer cement plate, even if under the condition that the cement pressing plate cracks, the reinforcement fiber grid cloth can also guarantee the integration of the fiber reinforcement multi-layer cement plate. The fiber reinforcement multi-layer cement plate can be custom made and cut according to use requirements and can improve construction speed.
Description
Technical field:
The utility model relates to concrete structure, specifically is a kind of fiber-reinforced multi-layer cement board.
Background technology:
At present, fibre reinforced composites with its excellent mechanical property and adapt to the modern project structure to stride greatly, towering, heavily loaded, demand that lightweight develops, just be applied to more and more widely receive Structural Engineering circle extensive concern in all kinds of civil engineerings.
Fibrous composite is of a great variety, and commonly used have carbon fiber, glass fiber, basalt fibre and an aramid fiber.Have advantages such as light weight, high-strength, high-elastic mould, high temperature resistant, acid-alkali-corrosive-resisting because of it, how be widely used in reinforcing, the reinforcement fields of civil engineering with the form of boundling or fabric.
Paper-faced gyp composite plate, calcium silicates light composite board, string lightweight composite plate, cement increased pressure board all are to mix the composite board that processes by multiple materials such as fibrous material, cement; The interpolation of fibrous material has obviously improved the mechanical property of sheet material; But because fibrous material is whole blending, mostly fibrous material is the inferior grade fiber, and sheet metal thickness is thinner relatively; Lack due structural, therefore only for the sheet material of safeguarding that is used for the non-bearing requirement; The glass fiber reinforced plastic light composite board then is through fibre-reinforced compound sandwich sheet material; The sandwich structure of self has improved the plate construction performance greatly, and the also corresponding mechanical property that improves sheet material of fibrous material can be applicable to load-bearing sheet material; But its manufacturing technology is complicated, and processing cost is higher.
The utility model content:
The utility model is intended to solve the above-mentioned problems that existing fiber reinforced composite board exists; And provide a kind of can the implementation structure mechanical property excellent, be easy to make, be convenient to processing, can be widely used in the building structure; Can be separately use, also can be used as the fiber-reinforced multi-layer cement board that the base plate of panel or the reinforced concrete slab of sandwich wall, floor uses as bearing plate.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of fiber-reinforced multi-layer cement board comprises cement increased pressure board, fortifying fibre grid cloth, and the interlayer of said cement increased pressure board is bonded with the fortifying fibre grid cloth through cementing agent.
Further, the interlayer of said layer 2-3 cement increased pressure board is bonded with 1-2 layer fortifying fibre grid cloth through cementing agent.
The cement increased pressure board is to add the sheet material that is pressed into through press, has advantages such as lightweight and good insulation, protection against the tide, sound insulation, fire prevention, is usually used in the partition wall and the furred ceiling of building construction.But the flexural strength and the shock resistance of cement increased pressure board 1 are relatively poor, can not stand bigger load, or brittle fracture very easily takes place when standing to bend load; The fortifying fibre grid cloth has the advantage of high strength, high elastic modulus, light weight; And high temperature resistant, acid-alkali-corrosive-resisting, caking property are strong; Generally be used for the reinforcing of body of wall or decorate use; The appearance of body of wall crackle and the development in crack be can effectively prevent, structure bearing capacity and deformation performance improved.The said fiber-reinforced multi-layer cement board of the utility model forms cement increased pressure board and the superimposed bonding of fibrous mesh cloth, therefore combines the common advantage of cement increased pressure board and fibrous composite.
Compared with prior art, the utlity model has higher tension, compressive strength and excellent bending resistance, shock resistance, fibrous mesh cloth can effectively prevent the generation and the development in crack in the cement increased pressure board; Under the greater impact load action; The fortifying fibre grid cloth impact energy that can dissipate largely; Improve the shock resistance of fiber-reinforced multi-layer cement board; Even under the situation that the cement increased pressure board breaks, the fortifying fibre grid cloth can also guarantee the globality of fiber-reinforced multi-layer cement board.The utility model can carry out specification customization and cutting according to instructions for use, can improve speed of application.The utility model can be widely used in the building structure, can use as bearing plate separately, also can be used as the panel of sandwich wall, floor or the base plate of reinforced concrete slab and uses.
Description of drawings:
Fig. 1 is the fiber-reinforced multi-layer cement board structural representation that is made up of individual layer fortifying fibre grid cloth.
Fig. 2 is the fiber-reinforced multi-layer cement board structural representation that is made up of two-layer fortifying fibre grid cloth.
Among the figure: 1-cement increased pressure board, 2-fortifying fibre grid cloth.
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is detailed.
Referring to Fig. 1, Fig. 2, the said this fiber-reinforced multi-layer cement board of the utility model is formed through the cementing agent bonding by layer 2-3 cement increased pressure board 1 and 1-2 layer fortifying fibre grid cloth 2.
The mesh of conventional fortifying fibre grid cloth 2 is generally 5mm * 5mm and two kinds of 4mm * 4mm (also can weave voluntarily by different mesh specifications according to actual demands of engineering), and width is generally 1m-2m, and length is generally 50m-300m; The thickness of cement increased pressure board 1 is 4mm-30mm.In the actual production, should confirm the thickness and the stickup number of plies of cement increased pressure board 1 according to the instructions for use of fiber-reinforced multi-layer cement board.
The production process of the utility model is:
By designing requirement (planar dimension of general fiber-reinforced multi-layer cement board is: width 0.6m～1.2m, length 1.8m～7.2m) cut out cement increased pressure board 1 carries out purified treatment with cement increased pressure board 1 surface, removes floating dust and outstanding hard impurity;
2. evenly smear cementing agent on cement increased pressure board 1 top layer of handling well;
3. the smooth paving of the fortifying fibre grid cloth that will cut out 2 is at cement increased pressure board 1 surface layer, and stretch-draw is even all around;
4. the cement increased pressure board of the upper strata being handled well 1 covers on the good fortifying fibre grid cloth 2 of paving;
5. according to the bonding number of plies of instructions for use, successively process according to above sequence of construction, and carry out pressurized treatments, until reaching requirement adhesion strength standard.
