Abstract
The utility model discloses a light-weight and high-strength concrete formwork made of composite materials, which comprises two fiber cloth layers. A sandwich layer is disposed between the two fiber cloth layers, a core material and a web made of composite materials are disposed in the sandwich layer, enclosing case frame is disposed on the peripheral edge of the sandwich layer, mounting holes are arranged on the enclosing case frame, and the enclosing case frame and the fiber cloth layers are integrally connected, so that the concrete formwork made of the composite materials is formed. Compared with other existing formworks, the light-weight and high-strength concrete formwork made of the composite materials has the greatest advantages that the concrete formwork is light in weight and high in strength, concrete construction speed can be obviously increased, construction expense can be saved, and the light-weight and high-strength concrete formwork is also applicable to concrete construction under special conditions.
Description
Technical field
The utility model relates to a kind of construction formwork, particularly relates to a kind of lightweight, high-strength composite material concrete blinding, and it can be widely used in building trade and other civil engineering field.
Background technology
At present, the concrete blinding that generally uses of building trade has wooden agglutination formwork, bamboo plywood form, steel form etc.Adopt wooden agglutination formwork and bamboo plywood form fluid concrete, shortcoming such as that its template ubiquity is easily deformable, do not grow application life, the concrete quality of cast is limited; And adopting the steel form fluid concrete, steel form can't satisfy the requirement of complicated concrete component for template, and steel form weight is big, will increase construction cost during use.In addition, owing to wood, bamboo resource lack day by day, not only the production of wooden agglutination formwork and bamboo plywood form, cost of manufacture increase day by day, nor are beneficial to ecological environmental protection.
Summary of the invention
To the deficiency of above-mentioned prior art, the purpose of the utility model provides a kind of lightweight, high-strength composite material concrete blinding, and this template can be widely used in building trade and other civil engineering field.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of lightweight, high-strength composite material concrete blinding comprise the bilaminar fiber layer of cloth; Be provided with laminboard layer between the described bilaminar fiber layer of cloth; In laminboard layer, be provided with core and composite material web, be provided with at the periphery of laminboard layer and enclose gridiron, be provided with installing hole on the gridiron enclosing; Enclose gridiron and the fiber layer of cloth fuses, form the composite material concrete blinding.
Preferably, described fiber layer of cloth, the resin that is adopted is epoxy resin or phenolic resins.
Preferably, described core is polyurethane foam, polyvinyl chloride foam or carbon foam.
Preferably, the angle of described composite material web and fiber layer of cloth is 30 ° to 60 °
Compared with prior art, adopt the template of composite material manufacturing to have the following advantages:
1, the composite material template has the characteristics of high strength, high rigidity.The panel of composite material template adopts the fiber layer of cloth of high strength, high elastic modulus, obtains bigger second moment of area by light-weight filler again simultaneously, can make the composite material template obtain bigger compressive strength and rigidity, makes template not yielding;
2, composite material template fiber layer of cloth and core bond performance are good, be difficult for to take place that panel and core are peeled off and the phenomenon of flaking, and can obviously improve the resistance to compression and the shear resistance of core, and the holistic resistant behavior of composite material template is significantly improved;
3, the composite material template has the characteristics of light weight.Adopt this template to carry out concrete construction, constructor's formwork and form removal can be hand-manipulated, do not take plant equipment, saved machinery expenses, and formwork and form removal speed are obviously accelerated, and improved work efficiency, have saved the engineering time;
4, composite material template good corrosion resistance is applicable to the construction of special concrete.With cloth and the panel that encloses the gridiron formation, can prevent the corrosion of all kinds of chemical agent effectively, go for the concrete construction under the specific condition;
5, the thermal and insulating performance of composite material template is very good, is applicable to the concrete construction of concreting in cold-weather or extremely frigid zones.The core that this template is related all is the non-conductor of heat, and this makes template possess good thermal and insulating performance.In the winter time or when extremely frigid zones carries out concrete construction; If adopt the composite material template to construct, because the thermal and insulating performance of template is very good, the heat in the time of can effectively keeping the concrete hydrating reaction; Guarantee concrete normal curing, be very beneficial for the concrete construction under the low temperature;
6, not only to have enough to meet the need access times height, long service life, cost of manufacture low for the composite material template, and field machining is convenient, compliance is strong, it is convenient to repair;
7, the demould time of composite material template is fast, easy to maintenance.Can the artificial demoulding during concrete demoulding, can not use engineering machinery auxiliary, stripping rate is fast, and demoulding rear pattern plate is easy to maintenance, just can clean template with simple tool.

The specific embodiment
To combine accompanying drawing that the utility model is described further below.
Referring to Fig. 1 to Fig. 3, the lightweight of the utility model, high-strength composite material concrete blinding comprise bilaminar fiber layer of cloth 1; Be provided with laminboard layer between the described bilaminar fiber layer of cloth 1; In laminboard layer, be provided with core 11 and composite material web 12, be provided with at the periphery of laminboard layer and enclose gridiron 2, be provided with installing hole 21 on the gridiron 2 enclosing; Enclose gridiron 2 and fuse, form the composite material concrete blinding with fiber layer of cloth 1.Described fiber layer of cloth 1, the resin that is adopted is an epoxy resin.Described core 11 is a polyurethane foam.Described composite material web 12 is 45 ° with the angle of fiber layer of cloth 1.
In the use,, be connected into type through the installing hole 21 that encloses on the gridiron 2 with the template of the utility model, mounting reinforcing steel bars in the groove that forms, and fluid concrete 3 gets final product.Certainly, during template construct, laying direction and the kind and the number of plies etc. of the layout of the kind of core 11 and height, the shape of enclosing gridiron 2 and size, installing hole 21 and aperture, fiber layer of cloth 1 all can be adjusted as required flexibly, specifically just do not give unnecessary details at this.
The above-mentioned a kind of embodiment that is merely the utility model not in order to restriction the utility model, any modification of being done within all spirit at the utility model and the principle, is equal to and replaces and improvement etc., all should be included within the protection domain of the utility model.
