Abstract

A network gluten structure takes the resin matrix composite material of fiber-reinforced thermosetting resins as the raw material and is made through one-time molding; a plurality of horizontal reinforced ribs and vertical reinforced ribs are staggerly arranged on the same plane to form a plurality of matrix-like arranged grid-structures. The composite material takes thermosetting resins as the basic material and fibers as the reinforced material, then the fibers are firmly bound in the thermosetting resin basic material so as to form a network gluten structure; the best way is to arrange anti-slip structures with convex-concave stripes or granular lines on the surfaces of the ribs.

Description

Net muscle works

Technical field

The utility model relates to a kind of net muscle works, refers to a kind of being used on building, the civil structure especially, and unifies the body formed net muscle structure of forming by polymer matrix composites through repeat layer.

Background technology

Present common reinforced concrete structure, mainly be meant by in concrete, adding bar construction, to improve a kind of combined material of concrete mechanics character, but by the sea, the building of waterside, the chemical plant, under the erosion environment conditions such as Wastewater Treatment Plant, concrete can produce slight crack, cause the rebar surface oxide film to destroy, the corrosion reaction takes place, thereby surrounding concrete is produced swelling stress, cause concrete cracking, peel off, because corrosion makes reinforcing bar useful area area reduce, reinforcing bar and grip of concrete weaken, structural bearing capacity descends, and then bring out the crack of other form, and more quicken corrosion of steel bar, cause badly damaged phenomenons such as structural deterioration.

The above-mentioned existing structure of detailed sight is real not to be difficult to realize, in the reinforced concrete structure, the oxidation corrosion of reinforcing bar, it is the one of the main reasons of destroying its structural integrity, and in the reinforced concrete structure, extremely shown in Figure 6 as Fig. 4, its steel mesh reinforcement body 10a is by self vertical crossover setting of most reinforcement bar 11a, then with iron wire 13a colligation or folder is fixed or mode such as welding is fixed in addition, only according to the made reinforcing cage of above-mentioned construction compound mode, bar constructions such as steel mesh reinforcement, except that the oxidation corrosion, during assembling reinforcement in order to the fixing folder of reinforcing bar, iron wires etc. are tied up if the leakage of colligation node takes place, it is too many to thread off, the welding point bending, dislocation, weld seam has human factors such as damage, can cause the integrality of reinforced concrete structure badly damaged phenomenon such as to be destroyed equally.

The utility model content

The utility model main purpose provides a kind of net muscle works that is used on building, the civil structure and has high strength, light weight and corrosion resistance characteristic.

According to the utility model, a kind of net muscle works, be that to be that raw material is one-body molded be made for polymer matrix composites with the fibre strengthening thermosetting resin, it is characterized in that, have most laterally ribs of being crisscross arranged and most lengthways of rod to form most checkerwork cell structures with rectangular arrangement on same plane, And is provided with on-slip and constructs on this majority rib surface.

Wherein, this composite material be with thermosetting resin as base material and with fiber as strengthening material, these fibers firmly are combined in this thermosetting resin base material.

Wherein, this thermosetting resin is to be thermosetting resins such as unsaturated polyester resin, epoxy resin, phenolic resins, alicyclic vinyl.

Wherein, this fiber is to be glass fiber, carbon fiber, aramid fiber or hdpe fiber fiber.

Wherein this on-slip structure is striated or the graininess lines for concave-convex surface.

The beneficial effects of the utility model are:

Net muscle works of the present utility model, it is on being used in building, civil structure the time, has high strength, light weight and characteristic such as corrosion-resistant.

Description of drawings

Relevant further feature of the present utility model and function, after cooperating following drawings and Examples to be further described, the phase can make the auditor that more detailed understanding is arranged, wherein:

Fig. 1 is a stereogram of the present utility model.

Fig. 2 is a vertical view of the present utility model.

Fig. 3 is a side sectional view of the present utility model.

Fig. 4 is the schematic perspective view of known steel mesh reinforcement.

The specific embodiment

As shown in Figure 1 to Figure 3, the net muscle works of the utility model embodiment is that the polymer matrix composites with the fibre strengthening thermosetting resin are raw material, and laminated processing mode is one-body molded to be made through repeating; And this net muscle works 10 is to be crisscross arranged by the horizontal rib of majority 11 and most lengthways of rod 12 on same plane and one is formed, thereby on the body of this net muscle works, form most checkerwork cells with rectangular arrangement, and on this rib, be provided with the striated or the graininess lines of concave-convex surface, so that increase the usefulness that bonds between this net muscle works and the concrete structure.

Aforementioned composite material is to reach with fiber as strengthening material as base material with thermosetting resin, this thermosetting resin as base material can be thermosetting resins such as unsaturated polyester resin, epoxy resin, phenolic resins, alicyclic vinyl, and should can be fibers such as glass fiber, carbon fiber, aramid fiber, hdpe fiber as the fiber that strengthens material; By above-mentioned material under the drawing effect of pulling equipment, continuous fiber with the impregnation resin adhesive liquid, intersect at grade and draw lengthways of rod 11 and horizontal rib 12, and repeatedly repeated overlapping traction repeatedly laminated after, make these in this thermosetting resin base material, be possessed high strength and the slim and graceful fiber reinforced composite net muscle works of quality by combination (bind) firmly thereby form one as the fiber that strengthens material.

Aforementioned net muscle works of the present utility model and known bar-mat reinforcement are compared, and possess at least following advantage:

1, density is little, in light weight: the density of polymer matrix composites is 1/4～1/5 of iron and steel;

2, intensity height: polymer matrix composites are near the intensity of steel, its It is a lot of that specific strength (ratio of tensile strength and density) is higher than steel;

3, corrosion-resistant: the polymer matrix composites of different cultivars can be anti-The corrosion of various acid, alkali, salt and organic solvent, corrosion resistance surpasses reinforcing bar;

4, the material adhesion is strong: thermal coefficient of expansion is compared more with steel and is connect Nearly cement, with concrete stronger in conjunction with bond stress, and muscle arteries and veins surface Lines and coarse particles outward appearance, more can increase and xoncrete structure between Bond stress;

5, plasticity height: laminate structures design is good plastic because having The property, muscle arteries and veins thickness, cross sectional shape, net muscle spacing and works length and width etc. Specification all can be adjusted in manufacturing process, and is following on-the-spot to cooperate Actual demand during construction; And

6, one-body molded: as to repeat horizontal rib and longitudinal rib after laminated Bar, its interface point do not need as shown in Figure 2 at grade again to tie up The modes such as bundle, welding link, and the intensity of interface point is good than the reinforcing bar goods.
