Description

TECHNICAL FIELD [0001] The present invention relates to a method for constructing a deck plate using an adhesive type insulation material,

The present invention relates to a method of constructing a deck plate using an adhered thermal insulation material, and more particularly, to a method of effectively preventing the occurrence of winter season disaster by suppressing heat loss of a concrete structure by using a deck plate having a heat insulating material, To a method of constructing a deck plate which can be reused and is economical.

Concrete can be manufactured by curing a concrete mixture containing an appropriate mix of cement, sand, gravel and water, and is used as an important material in civil engineering or building structures because it can withstand natural winds such as water, fire, and earthquakes.

These concrete are produced in a batch plant and then transported to a concrete truck called a concrete mixer, and then poured and cured in a concrete structure. The batch plant is to weigh the amount of concrete dough one time, put it into the mixer, discharge the completely mixed concrete, and then insert the new concrete dough.

When concrete is poured, hydration is accompanied by hydration. Hydration is a phenomenon in which a solute molecule or an ion attracts several water molecules around it to form a single molecule group. Therefore, Hydration heat is generated in the process.

The heat of hydration raises the internal temperature of the concrete structure, resulting in a temperature difference between the inside and the outside of the concrete structure, which is a cause of the temperature cracking.

Such temperature cracks necessarily occur at the time of curing because the internal temperature rises due to hydration heat and the temperature difference between the inside and the outside of the concrete structure becomes 30 ° C or more.

In addition to the temperature cracks due to the temperature difference between the inner and outer surfaces of the cracks, there is also a shrinkage crack due to the drying and shrinking of the outer surface of the concrete structure during the curing process.

On the other hand, deck plates are also used for the convenience of the concrete slab construction. However, the construction using the conventional deck plate has a problem that it is vulnerable to the East Sea when it is poured or cured in the winter season because the characteristics of the substructure of the deck plate are not considered sufficiently. In this connection, Fig. 1 shows a frost damage which can be generated in a concrete structure due to a decrease in the temperature of the winter season.

Generally, since the deck plate is made of steel, there is a problem that it is difficult to maintain the temperature of the winter concrete because of high heat conductivity. In addition, since the thickness of the concrete applied to the deck plate is relatively thin (10 cm to 15 cm), it is vulnerable to frost damage.

In order to solve such a problem, conventionally, during the longevity as shown in FIGS. 2A and 2B, or by turning the jet heater, the winter is maintained. However, this method has a disadvantage that the risk of fire is large, there is a fear of suffocation, the problem of environmental pollution due to the excessive emission of carbon dioxide, and troublesomeness due to the use of additional equipment are still present.

Accordingly, it is possible to simplify the work during the curing of the concrete, so that the work can be simply performed. Further, it is required to develop a method for constructing the deck plate which is economically advantageous because it can be continuously reused even after curing is completed.

Hereinafter, a method of constructing a deck plate using the adhered thermal insulation material proposed by the present invention will be described in detail with reference to the drawings.

3 is a flowchart for explaining a deck plate construction method according to an embodiment of the present invention. However, the steps shown in FIG. 3 are not essential, so a deck plate construction method having more steps or fewer steps may be implemented. Also, the steps shown in FIG. 3 are interdependently linked, and it is possible that each step may be implemented separately or integrally as shown in FIG.

Referring to FIG. 3, first, a concrete structure is installed by installing a concrete (S10), and a deck plate is installed on a ceiling portion of the concrete structure (S20).

The deck plate may be a flat deck plate or a concave-convex deck plate. In this regard, Figs. 4A and 4B show one embodiment of a deck plate which can be applied to the present invention.

The planar deck plate 10 of FIG. 4A is generally formed in a planar shape, and its size is formed corresponding to the size of the ceiling portion of the concrete structure.

The concavo-convex deck plate 12 of FIG. 4B has a shape in which the protruding surface 14a protruding downward and the recessed surface 14b of the drawn-in shape are periodically repeated. The protruded surface 14a and the recessed surface 14b are formed along the longitudinal direction of the uneven deck plate 12 and are arranged side by side. The projecting surface 14a and the drawing surface 14b are connected to each other by an inclined surface 14c.

Next, in order to conserve the concrete structure, a heat insulating material is attached to the lower part of the deck plate using the attaching means (S30), and then the concrete structure is cured (S40).

The present invention can use a styrofoam (20) or a corrugated cardboard (22) as a heat insulating material. Since such a heat insulating material is easily obtainable from around us, the curing can be performed at a much lower cost than the conventional one.

Further, since the present invention does not use any separate equipment for disposing the heat insulator, it is possible to reduce the complexity of the facility, and it is possible to detach and attach the heat insulator so that the insulator can be continuously used.

5a and 5b show an embodiment in which a heat insulating material is attached to a planar deck plate which can be embodied according to the present invention, In which the heat insulating material is attached.

5A and 5B, when the flat deck plate 10 is used, the heat insulating materials 20 and 22 having a planar shape are attached.

6A and 6B, when the uneven deck plate 12 is used, the heat insulating members 20 and 22 made of a concavo-convex shape corresponding to the uneven deck plate 12 are attached . That is, the irregular-shaped heat insulators 20 and 22 have a shape in which protruding portions protruding downward and protruding recessed portions are periodically repeated.

As one example of the styrofoam 20 that can be used as a heat insulating material, a heat-resistant styrofoam heat insulating material can be used. Styrofoam is very weak in heat, so it melts early in the event of a fire and not only serves as a medium to spread the fire, but also can cause serious injury due to toxic gas generated during combustion.

In order to solve this problem, the present invention can use the heat styrofoam heat insulation material. The heat-styrofoam heat insulating material is produced by mixing porous mineral particles having a large number of pores on the surface and inside thereof, such as zeolite, bentonite, pearlite, illite, etc., with expanded polystyrene particles and compression- . These styrofoam heat-insulating materials have the effect of absorbing the toxic gas generated by the styrofoam combustion when the fire occurs and the porous mineral particles mixed in the styrofoam thermal insulation material significantly reduce the toxic gas emission, and the porous mineral particles absorb the styrofoam- It is possible to prevent fire propagation by the styrofoam melt.

Therefore, the porous mineral particles used in the present invention have many pores formed on the surface and inside thereof such as zeolite, bentonite, perlite, and ilite generated by the action of volcanic clusters, and toxic gases generated by styrofoam combustion It can be used if it can absorb the melt. These porous mineral particles do not inhibit the adiabatic effect peculiar to the styrofoam insulation due to the pores therein.

In forming the flame-retardant styrofoam heat-insulating material of the present invention, it is preferable that the porous mineral particles and the expanded polystyrene-based particles are mixed at a volume ratio of 1000: 1 to 1000: 800 in consideration of a desired effect of the present invention, , And even more preferably in a volume ratio of 1000: 10 to 1000: 100. The average particle diameter of the porous mineral particles used in the present invention is preferably 80 to 200 mesh, in consideration of mixing dispersibility with the expanded polystyrene particles and flame retardancy.

On the other hand, an example of a corrugated cardboard 22 usable as a heat insulating material is shown in Figs. 7A to 7D. 7A to 7D are corrugated cardboard structures applicable to the deck plate construction method of the present invention.

FIG. 7A shows a double faced corrugated fibreboard as a corrugated cardboard which can be applied to the present invention.

As shown in FIG. 7A, the double-sided corrugated cardboard can be constructed by inserting a corrugated sheet 26 between a surface liner 24a and a backside liner 24b, which are a pair of liner spaced apart at a predetermined interval have.

The corrugated cardboard 26 may have a corrugated shape having a plurality of corrugations, and corrugated cardboard may be manufactured by attaching a corrugated cardboard to the liner using an adhesive. However, the shape of the corrugation sheet applicable to the present invention is not limited to this corrugated shape, and corrugated sheets having different shapes may be used.

The liner imparts resistance to mechanical impact and weather conditions, and the corrugation can provide thickness to the corrugated cardboard and provide relative resilience to compression upon impact while increasing robustness and flexibility.

As an example of the corrugated cardboard applicable to the present invention, the corrugation 26 may be formed of a multi-layer structure or more to increase the rigidity of the corrugated cardboard.

It is also possible to implement a corrugated cardboard having various rigidity by changing the material of the front liner 24a or the back liner 24b.

As another example of the corrugated cardboard applicable to the present invention, the corrugation 26 may have a waveform having a small size of 0.7 to 1.0 mm.

In the case of forming the corrugation waveform to be small in this way, the contact area between the corrugation of the corrugation 26 and the liner is narrowed, and the heat transfer area is narrowed at the time of heat transfer.

That is, the heat transfer from one liner to the other liner is delayed and the thermal conductivity is lowered, so that the heat of hydration of the concrete structure can be more efficiently preserved.

The upper surface of the surface liner 24a may be coated with a waterproof coating solution to protect the concrete structure against external weather changes.

When the liner and the corrugated paper 26 are made transparent, the transparency of the light is increased. When the liner and the corrugated paper 26 are made of black, the heat collection effect is enhanced. On the other hand, since it has the effect of heat reflection when it is used by treating it with silver foil, it is more advantageous in the construction of concrete in the middle.

On the other hand, FIG. 7B shows a single faced corrugated fibreboard having the simplest configuration as a corrugated board which can be applied to the present invention.

As shown in FIG. 7B, the one-side corrugated cardboard can be constructed by attaching one surface liner 24a to one side of the corrugated paper 26 formed in a bony shape.

Meanwhile, FIG. 7C shows a double wall corrugated fiberboard as a corrugated board applicable to the present invention.

As shown in FIG. 7C, the double-sided double-sided cardboard can be formed by attaching the single-sided cardboard of FIG. 4B to the double-sided cardboard of FIG. 4A.

In other words, corrugated sheets 26 of corrugated shape may be inserted between the three liners 24a, 24b and 24c spaced apart at a predetermined interval.

Here, the corners of the corners can be classified into A, B, C, and E according to the purpose. A, B, and C are mainly used for external packaging, and A and E are used for inner packaging, and E-bone can be used mainly for individual packaging. Table 1 below shows the characteristics according to the type of bone.

Type of goal Height of bone (mm) Number of bones (per 30 cm) A goal 4.5-4.8 34 ± 2 B Goals 2.5 to 2.8 50 ± 2 C goal 3.5 ~ 3.8 40 ± 2 E goal 1.1 to 1.4 93 ± 5

The corrugated paper 26 of the double-sided corrugated cardboard is generally formed by combining the A and B bones. In addition to the AB bones, a combination of AA, AC, AE, BC, and BE can also be used .

AA is a double-sided double-sided corrugated cardboard having high vertical compressive strength and is mainly used for packing heavy or destructible products, and is also used for concrete curing of the present invention to provide high rigidity.

On the other hand, FIG. 7D shows a triple wall corrugated fiberboard as a corrugated board applicable to the present invention.

As shown in FIG. 7D, the triple corrugated cardboard can be formed by attaching the single-side corrugated cardboard of FIG. 7B to the double-sided corrugated cardboard of FIG. 7C.

In other words, corrugated sheets 26 of a corrugated shape may be inserted between the four liners 24a, 24b and 24c spaced apart at a predetermined interval.

Triangular corrugated boards are also used in combination with wood, and are usually used in combination with AAA, AAB, and AAC.

The triple corrugated cardboard has been developed for converting a wooden box or a heavy box into a corrugated board, and has strong pressure resistance and weather resistance, and is excellent in heat insulation and airtightness. Packing of more than 100kg is also possible. Therefore, it can be used for concrete curing requiring high heat insulation and rigidity.

On the other hand, the corrugated cardboard which can be applied to the present invention is preferably waterproof corrugated cardboard. The above waterproof corrugated cardboard can be conformed to the Korean Industrial Standards KS T 1012 standard of the Agency for Technology and Standards of the Ministry of Commerce, Industry and Energy.

Waterproof corrugated cardboard can be divided into three types according to waterproof performance: water-repellent, water-resistant and water-resistant cardboard.

Water repellent corrugated paper refers to corrugated paper that has been surface-treated to prevent water from penetrating into water droplets when water is dropped for a short period of time.

A corrugated cardboard is a corrugated cardboard that is processed so that it does not pass through water even if it is in contact with water for a long time.

Corrugated cardboard is a corrugated cardboard liner, corrugated cardboard corrugated paper, adhesive or corrugated cardboard corrugated cardboard so that its strength will not drop if it is flooded for a long time.

The deck plate construction method of the present invention can select the corrugated cardboard properties (rigidity, heat insulation performance, order performance) suitable for the ambient temperature or the concrete curing environment such as the target structure.

Further, where the temperature difference between the inside and outside is expected to be very large, it is possible to use double or triple corrugated cardboard having high heat insulation performance, or to apply corrugated paper multiple layers.

Meanwhile, the heat insulating material applicable to the present invention can be used by adhering the styrofoam 20 and the corrugated cardboard 22. Since the heat insulating material has an air layer, the heat insulating effect and the moisture-proofing effect are improved, and consequently, condensation and moisture can be prevented from permeating through.

Specifically, a corrugated cardboard 22 made of plastic is adhered tightly to the surface of the styrofoam 20 having an appropriate size and thickness by an adhesive to form a heat insulating material. The corrugated cardboard 22 has a styrofoam 20 The upper and lower portions of the styrofoam 20 are formed by bending a horizontal fixing piece respectively attached to upper and lower surfaces of the corrugated cardboard 22, The insertion groove into which the vertical fixing piece is fitted can be formed.

The upper and lower surfaces of the styrofoam 20 are respectively provided with insertion grooves for respectively fitting upper and lower vertical fixing pieces of the plastic corrugated cardboard 22 to prevent the vertical fixing pieces from protruding from the back surface of the styrofoam 20 . The upper and lower portions of the corrugated cardboard 22 are integrally bent and integrally formed with upper and lower surfaces of the styrofoam 20, respectively. The upper and lower portions of the corrugated cardboard 22 are bent at right angles to the edges of the corrugated cardboard 22, The upper and lower horizontal fixing pieces and the vertical fixing pieces prevent the styrofoam 20 from falling or prevent the corrugated cardboard 22 from being opened.

In addition, a plurality of grooves may be formed on the mounting surface of the corrugated cardboard 22 so as to allow the adhesive to penetrate. These grooves serve to attach the styrofoam 20 even more firmly.

Since the horizontal fixing piece, the vertical fixing piece and the groove are formed in the corrugated cardboard structure, the heat insulating material can prevent the styrofoam from falling off or the corrugated cardboard being worn out. In addition, since the air layer is formed through the plurality of hollow portions formed at appropriate intervals in the inside of the plastic corrugated cardboard 22, the heat insulating effect and the moisture-proofing effect of the heat insulating material are improved.

On the other hand, in the method of constructing the deck plate of the present invention, the double-sided tape 30, the magnet 32, the fixing core 34 and the like can be used as the attachment means. 8A and 8B show an example of attaching a deck plate and a heat insulating material using a double-sided tape, FIGS. 9A and 9B show an example of attaching a heat insulating material and a deck plate using magnets, An example of attaching a deck plate and a heat insulating material using a core material is shown.

8A and 8B, the double-sided tape 30 can be disposed on the upper surface of the heat insulating material. The double-sided tape 30 can adhere the lower surface of the deck plate to the upper surface of the heat insulating material and, if desired, separate the heat insulating material from the deck plate.

9A and 9B, the magnet 32 can be disposed inside the heat insulating material. The magnetic force generated by the magnet 32 can adhere the deck plate to the heat insulating material and can easily separate the heat insulating material from the deck plate if desired.

The magnet 32 may be disposed inside the corrugated cardboard 22, as shown in Fig. 9B. It is possible to provide a hollow space for disposing the magnets 32 by removing the back liner 24b and a part of the corrugation 26 while leaving the surface liner 24a as it is. The magnet 32 can be fixed by arranging the magnet 32 inside the hollow space without a separate structure.

10 shows a bottom perspective view. Referring to FIG. 10, when the uneven deck plate 12 is used, the fixing core 34 can be used as an attachment means. The fixing core (34) is configured such that both tip ends thereof are inserted into the inclined surface (14c) of the uneven deck plate (12). In other words, one proximal end of the fixing core 34 is inserted into a first inclined face connecting the first protruding face, which is one of the plurality of protruding faces, to the first pulling face, and the other distal end of the fixing core 34 is inserted into the first And is inserted into the second inclined surface connecting the projecting surface and the second drawing surface.

The fixing core 34 is designed so that the heat insulating material can be easily attached to the irregular deck plate 12 and the plurality of fixing core members 34 are spaced apart from one another on each of the protruding faces 14a, Can be improved.

Meanwhile, it may further include a step of installing the supporting member 40 after the step S30. In this connection, Figs. 11A and 11B show a structure for supporting a heat insulator using a supporting member.

Referring to FIG. 11A, it is preferable that the first portion of the heat insulating material, which is brought into contact with the upper end of the support member, has a material having higher rigidity than the other portions. This is to prevent the upper end (42a) of the support member (40) from being damaged or damaged.

11A, a part of the heat insulating material corresponding to the protruding surface 14a of the irregular deck plate 12 may be made of the foamed foam 20 while using the corrugated cardboard 22 as the heat insulating material .

The upper portion 42a of the support member 40 is raised to the upper side and the upper portion 42a of the support member 40 is brought into contact with the first portion having greater rigidity. .

When the upper end 42a of the support member 40 is directly contacted with the corrugated cardboard 22, pressure may be applied to the corrugated cardboard 22 at the contacting portion to cause deformation. However, when the contacting portion is the styrofoam 20, Is minimized and reusable.

When the curing is completed, the elevating portion 42 is lowered and the heat insulating material adhered to the deck plate can be removed. In the deck plate construction method of the present invention, since the heat insulating material is detachable, the heat insulating material separated after curing can be used again in the curing process of other concrete structures.

According to the method of constructing the deck plate of the present invention, since the lower part of the deck plate is insulated by the heat insulating material, it is possible to prevent the frost damage which occurs in the winter season and to reduce the temperature cracking according to the decrease in temperature difference inside and outside of the concrete. The degradation phenomenon can be prevented. In addition, since it can replace the existing curing method for lignite, there is no risk of fire or pollution, and it is very economical because a lot of lignite is unnecessary. In addition, since the heat insulating material can be attached and detached without any additional process such as perforation of the nut, there is no fear of leakage or corrosion of the nut portion, and the cost and time for the additional process are reduced. In addition, since a partially rigid heat insulating material is used, the heat insulating material can be prevented from being damaged, and thus it can be reused many times and cost can be reduced.

The present invention can also be embodied as computer-readable codes on a computer-readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may be implemented in the form of a carrier wave (for example, transmission via the Internet) . The computer readable recording medium may also be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner. In addition, functional programs, codes, and code segments for implementing the present invention can be easily inferred by programmers of the technical field to which the present invention belongs.

In addition, the above-described method and apparatus using the same may be applied to a case where the configuration and method of the embodiments described above are not limitedly applied. As shown in FIG.
