Description

Deck plate with eco-friendly insulation {DECK PLATE WITH ECO-FRIENDLY HEAT INSULATOR}

The present invention relates to a deck plate equipped with an eco-friendly insulating material, and more particularly, an eco-friendly insulating material that can reduce the cost of manufacturing the insulating material and prevent environmental pollution caused by waste treatment by including the insulating material manufactured by recycling waste materials. It relates to a deck plate equipped with.

In general, a concrete structure is a composite structure in which concrete as a compression member and reinforcing bars as a tension member are used together. After a formwork is installed, reinforcing bars are placed, and then the concrete is poured, curing and dismantling the formwork.

In such a conventional concrete structure, a formwork is installed with plywood, square materials, etc. to pour concrete, and after reinforcing reinforcing bars, etc. in the formwork, the process of pouring and curing the concrete and dismantling the formwork is required. there was.

As a way to solve this problem, a truss girder deck plate that can support the weight of concrete that is erected between beams, which is a structure for constructing a concrete structure, and the concrete poured on it and the concrete itself generated during the curing of the concrete is proposed. has been

Compared to conventional reinforced concrete structures such as wooden formwork, deck plate has the function of omitting temporary posts until concrete is cured, and the thin plate steel plate attached to the lower part of the truss girder acts as a formwork, allowing time to assemble and dismantle separate formwork. It takes advantage of being there.

If a truss girder deck plate is used, concrete is poured and cured after the deck is installed, then the formwork is dismantled and a separate insulation is installed later. There were problems such as being longer.

In order to solve the above-mentioned problems, a deck in which a truss gunner is combined with a truss gunner on the upper plate and a thermal insulation material on the lower part is integrated, and the deck is being developed.

However, buildings with a certain standard such as apartments, villas, townhouses, high-rise buildings, and factory buildings, where insulation deck plates can be used, do not generate harmful gases in case of fire and have high chemical and physical strength and durability, so they are non-combustible and have a long lifespan. Or a flame-retardant thermal insulation material is required.

Styrofoam (EPS), urethane, glass fiber, etc. are used as thermal insulation materials that have been conventionally used to satisfy the above-mentioned characteristics. As a result, there is a problem in processing.

In the case of incineration, not only the problem of air pollution arises due to soot, odor and toxicity generated during incineration, but also the cost burden for incineration treatment is large due to its flame retardant properties. There is another method of compression and landfilling, but this also does not rot, so there is a problem that causes secondary pollution or lack of landfill sites, causing serious environmental pollution.

For this reason, a recycling method has been proposed. In the case of waste Styrofoam, a number of methods such as crushing and using it on sludge such as cement and gypsum are known, but they are not universalized.

In particular, in the case of waste glass fiber, once it is formed, it is not melted by heat, so recycling is very limited.

In addition, it is difficult to recycle waste materials such as waste wood, waste urethane, waste tires and waste fibers that are discarded after being used as building materials, and incineration or landfill causes environmental pollution and pollution, which is a big problem. However, there is currently no proper recycling method.

Therefore, there is a need for a deck plate including an eco-friendly insulating material that can recycle waste materials that have been difficult to recycle in the past.

Each may be welded to form a triangular cross-sectional shape.

The upper reinforcing bar 11 and the lower reinforcing bar 12 may be composed of deformed reinforcing bars having irregularities formed on the surface so that the poured concrete can be easily attached. And, the upper reinforcing bar 11 may be composed of a nominal dimension of 10 to 14 mm, the lower reinforcing bar 12 may be composed of a nominal size of 10 to 14 mm, and the lattice reinforcing bar 13 has a diameter of 5 mm to 7 mm. can

The types and sizes of the upper reinforcing bars 11, lower reinforcing bars 12, and lattice reinforcing bars 13 described above may be changed and combined according to required physical properties such as tensile strength, yield strength and elongation required in the part used.

The plate 20 supports the load of the concrete poured on the deck plate 100 provided with the eco-friendly insulation material and serves to prevent the concrete from leaking to the outside. In order to perform this role, the plate 20 is composed of a galvanized steel sheet having a thickness of 0.5 mm to 0.7 mm and may be formed in a rectangular plate shape. The plate 20 may be formed by combining a plurality of steel plates. Here, the plurality of steel plates constituting the plate 20 may be combined in a form in which both ends are bent in order to prevent the concrete from leaking to the outside.

In addition, the plate 20 may be coated with a ceramic coating agent to prevent corrosion during the curing process of the concrete. Here, the ceramic coating agent may include an organic resin, silicone acrylate, and polysilsesquioxane, and specifically may be constituted of an organic-inorganic composite coating agent represented by the following [Formula 1].

[Formula 1]

These ceramic coatings can be cured using a radiation source such as ultraviolet (UV) or electron beam radiation, and curing of the radiation-curable compound can occur due to free radical polymerization or other reactions involving the radiation-curable compound.

Here, the organic resin may be composed of a thermosetting resin or a thermoplastic resin to improve the adhesion of the plate 20, specifically, a silicone resin, a melamine resin, an acrylic resin, a phenoxy resin, a thermoplastic polyester, polyamide, vinyl It may be composed of any one of leadene resin, polyurethane, polyolefin, polysulfide rubber, nitrile rubber, and epoxy resin. The above-mentioned organic resin is usually a thermosetting resin composition, and the type thereof is not limited.

Silicone acrylate serves to secure nonflammability, acid resistance and scratch resistance, and can be synthesized by silanizing silica sol and silica. In addition, silicone acrylate can be synthesized by hydrolysis and condensation of a plurality of silanes.

Polysilsesquioxane is denoted as (RSiO1.5)n and is a compound containing one or more siloxane bonds (Si-O-Si). can have a structure. In this case, R may be composed of hydrogen, alkyl, alkylene, allyl, allylene, or a functional alkyl, alkylene, allyl, or allylene derivative.

Preferably, the polysilsesquioxane used in the ceramic coating agent of the present invention may be composed of polyhedral oligomeric silsesquioxane having one or more reactive functional groups substituted and having a cage structure. Here, the polyhedral oligomeric silsesquioxane having one or more functional groups substituted and having a cage structure may include 8 to 20 silicon atoms in a molecule.

In addition, a reactive functional group may be substituted in at least one of the silicones of the polyhedral oligomeric silsesquioxane having a cage structure, and a non-reactive functional group may be substituted in silicones in which the reactive functional group is not substituted.

As a reactive functional group is substituted in at least one of the silicones of the polyhedral oligomeric silsesquioxane having a cage structure, mechanical properties of a coating film or binder resin formed during photocuring of the ceramic coating agent can be improved.

In addition, by substituting a non-reactive functional group for the remaining silicones in which the reactive functional group is not substituted, the frequency or probability of exposing the siloxane bond (-Si-O-) to the outside can be greatly reduced, thereby increasing compatibility with other organic materials. .

In the mixing step (S200), each waste material pulverized through a grinder is put into a mixing tank, and the pulverized waste material inside the mixing tank is mixed with each other by rotational force.

The adhesive coating step (S300) is a step in which waste materials are mixed in a mixing tank to form a mixture, and an adhesive is sprayed onto the mixture, so that the mixture and the adhesive are coated in a predetermined ratio.

In this case, the mixing ratio of the mixture and the adhesive is 80 to 99% by weight of the mixture, and 1 to 20% by weight of the adhesive, so that a properly dried mixture can be formed. In order to maintain an optimal state capable of viscous deformation so that the mixture is easily recycled, the ratio of the mixture to the adhesive may be adjusted according to the type of waste material.

Here, as the adhesive, an adhesive such as urethane or an epoxy component may be used.

The mold inserting step (S400) is a step of inserting the adhesive-coated and dried mixture to be uniformly dispersed in the mold of a certain standard, and the press-compressing step (S500) is to compress the mixture to a certain thickness using a press. It is a step to

Here, the mixture inserted into the mold may be pressed at a pressure of 8 to 10 kg/cm 2 by a press, and may be thinly compressed into a plate form constituting 20 to 80% of the initial volume.

The high-temperature aging and chemical reaction step (S700) is a process of aging and chemically reacting the mixture supplied with dry steam at a high temperature (90~130℃) for a predetermined time (2~10 minutes) to form a bulk insulation board. is a step

The board detachment step (S800) and the board drying step (S900) are steps of demolding the insulation board from the mold and then drying the insulation board in a drying device or drying room (60 to 70° C.) for a certain period of time to generate microwaves.

Finally, the board cutting step ( S1000 ) is a step of cutting the insulation board according to the size of the plate 20 using a cutter.

The heat insulating material 30 manufactured through the above-described manufacturing method may be bonded to the lower portion of the plate 20 through the fixing member 31 . Here, the fixing member 31 serves to prevent separation of the insulator 30 due to the load applied from the upper side of the plate 20 . In order to perform this role, the fixing member 31 may be formed of a fastener made of metal, plastic, or the like.

On the other hand, Figure 3 is shown as a configuration in which the fixing member 31 penetrates and fixes the plate 20 and the heat insulating material 30, but this does not limit the content of the present invention and the fixing member 31 performs the above-described role. Note that it is sufficient to perform and there are no special configuration restrictions.
