Description

Half composite concrete wall construction method using composite connector {HALF-COMPOSITE WALL CONSTRUCTION METHOD USING CONNECTOR}

The present invention relates to a method for constructing a half composite concrete wall using a composite connecting material. More specifically, in the concrete wall of the heat dissipation structure (sandwich wall form) installed to form the insulation layer on the outer wall of the building, the composite connecting material which can greatly increase the bending rigidity of the wall as well as the efficiency of the energy loss blocking caused by the thermal bridge phenomenon. It is about a half composite concrete wall construction method.

In the existing concrete wall structure, for example, as shown in Figure 1a adopts a heat-insulating structure that installs the heat insulating material 10 on the inner side of the outer wall 40 of the building, the floor heating 20 is mainly dominated In Korea, the loss of heating energy flowing out to the outer wall 40 through the floor slab is pointed out as a problem.

Accordingly, the outer insulation structure, which is one of the element technologies for realizing zero energy and zero carbon building structures, which are being promoted nationwide for the purpose of preventing global warming, is formed through an outer wall through the floor slab 30 as shown in FIG. The heating energy transmitted up to 40 is blocked by the heat insulator 10 installed outside the outer wall 40 so that a high energy saving effect can be expected.

However, in the case of the external insulation structure, in order to install the heat insulating material 10 outside the outer wall, construction difficulties such as scaffolding for external work, additional construction of the protective finish material 50, and durability of the heat insulating material exposed to the outdoor environment Due to the problem in Esau, it has not yet reached the commercialization stage.

In order to selectively collect the disadvantages of the heat-insulating structure and the advantages and disadvantages of the external heat-insulating structure, a so-called interrupted heat inserting the insulating material 10 in the middle of the concrete walls 41 and 42 as shown in FIG. 1C. The concept of structural walls has been introduced.

That is, according to the method of attaching the wall of the sandwich panel form in which the insulation is formed between the walls as the outer wall.

According to such a concept, a number of techniques for manufacturing a wall of a heat dissipation structure composed of both concrete walls and insulation materials have been introduced.

For example, as shown in FIG. 1D, a synthetic concrete panel 60 is introduced.

A core member 61 provided at both sides of the mesh-type iron core 62 embedded therein so as to be exposed to the outside, and having a plurality of connecting sheath connectors 63 protruding from the surface thereof; It can be seen that the bonding member 64 is bonded to the protruding portion of the share connector 63 so as to be composed of a covering member 64 (both walls) attached to the surface of the core member 61.

That is, the sheath connector 63 is joined to each other by the cladding member 64 to act as a composite concrete wall so that the cladding member 64 behaves integrally, and the core member as a heat insulating material between the cladding member 64 ( 61) is formed to function as a wall of the interrupted heat structure.

However, the composite concrete wall, which is based on the integral behavior of the cladding member 64, has these iron cores and / or connectors 62 and 63 due to the requirement to connect or join the cladding members (both walls) to each other. There is a problem in that energy loss, that is, a heat bridge occurs through.

That is, the iron core and the connecting material of the wall installed in the composite concrete wall has a problem that acts as a cause of halving the advantages of the heat-disrupting structural wall proposed for the purpose of preventing the heating energy loss by the thermal bridge phenomenon.

In addition, in order to fundamentally exclude the thermal bridge phenomenon, the non-bearing wall, which is simply attached to both outer walls and a heat insulating material, that is, a non-synthetic wall formed of a heat dissipation structure, is economical due to the low structural performance due to the non-synthetic behavior of the outer wall and the heat insulating material. There was a problem of this deterioration.

That is, it was pointed out that the resistance against the bending moment due to the load acting on the wall is significantly lower than that of the composite concrete wall.

Therefore, in the concrete wall of the heat dissipation structure, there is a need for the development of technology for a new concept concrete wall that can have both the advantages of the composite concrete wall and the non-synthetic type.

FIG. 1E illustrates a method of constructing a wall on the exterior of a building, and a method of constructing a composite concrete wall 70 at a factory and constructing using a connecting steel not shown on the exterior wall of the building can be confirmed.

Therefore, the construction of the finished composite concrete wall had a disadvantage in that the construction of the large-scale composite concrete wall was not easy because the connecting steel had to bear all the load of the composite concrete wall.

Accordingly, the present invention uses a synthetic connecting material for the integral behavior (synthesis) of the outer wall in the heat dissipation structure, in particular, in order to minimize the thermal bridge phenomenon, the composite connecting material is a very low thermal conductivity FRP material or epoxy coated rebar In addition, by using the shape of the composite connecting material, the composite concrete wall not only having excellent thermal insulation performance but also structural performance is also manufactured as a half composite concrete wall and installed outside the building. The technical problem to solve the provision of the construction method of the half composite concrete wall using the finished composite connecting material.

The present invention

First, the composite concrete wall is composed of both walls, insulation and composite connecting material.

Therefore, the present invention is to produce a composite concrete wall using a synthetic connector in a particularly half way. That is, a half composite concrete wall is first manufactured in a factory using one side wall, an insulation material, and a composite connecting material, and after the half composite concrete wall is installed outside the building, the other side wall is constructed by using a formwork for final synthesis. Type concrete walls will be constructed.

Such composite concrete walls should be able to prevent thermal bridges and to be able to synthesize both walls.

Therefore, in order to minimize the thermal bridge phenomena transferred to the concrete wall in the wall of the heat dissipation structure, the connecting material connecting the two concrete walls is to be made of a synthetic connecting material using FRP material or epoxy coated rebar.

In particular, the thermal conductivity of FRP composite joints is about 2/1000 ~ 1/100 times smaller than the thermal conductivity of shear connectors made of steel used in the wall of the heat dissipation structure. There is an advantage that can minimize (thermal bridge phenomenon).

In addition, FRP composite connecting material itself has tensile strength equal to or higher than that of steel, and thus can exhibit sufficient mechanical strength necessary for the composite behavior of inner and outer walls, and thus significantly improved compared with conventional girder concrete walls. It is possible to express the equivalent bending strength while maintaining the insulation performance.

In addition, in order to economically and effectively prevent thermal bridges, the present invention was also able to use a synthetic connecting material coated with epoxy on the rebar.

In addition, the composite connecting member of the present invention is to be formed in the shape of a wave, rod, I or H, lattice in shape to ensure the composite capacity of the walls while ensuring sufficient bending rigidity of the finished wall. .

Particularly, the composite connectors formed by corrugation improved the flexural rigidity of composite concrete walls by enhancing the flexural rigidity of composite connectors. There is an advantage.

Furthermore, the waveform composite coupling member may be formed not only in a planar shape but also in a three-dimensional shape to further enhance the composite performance of the waveform composite connecting member.

Such a three-dimensional wave form composite connecting material has a further advantageous advantage to ensure the bending rigidity of the wall.

Second, in the installation method, the composite connecting member is installed in the longitudinal direction or the longitudinal direction of the composite connecting member disposed so as to extend from the inside of one wall to the inside of the other wall through the heat insulating material, so that both walls behave structurally integrally. Compared with the existing non-synthetic concrete walls, the flexural moment resistance can be increased by more than 50% ~ 70% due to the increased moment arm length by the composite connecting material while maintaining the equivalent thermal insulation performance. I did it.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

First, as shown in FIG. 2A, the half composite concrete wall 100 of the present invention is installed by using the connecting steel 310 shown in a simplified manner on the outer wall of the building 300.

Such a building may be divided into a slab 30 and a floor heating 20 formed on the slab 30.

In this case, the slab 30 may be classified into a precast method or a site casting method, but when the half composite concrete wall 100 is used as in the present invention, the slab 30 may be constructed in a site casting method.

In this case, the half composite concrete wall 100 is manufactured to include one side wall 110, a planar or three-dimensional composite connection material 200 and a heat insulator 130.

The half composite concrete wall 100 is a planar or three-dimensional composite connecting material 200 is used to look at the composite connecting material 200 first, and look at the method of manufacturing a half-synthetic concrete wall as follows.

That is, looking at the embodiments of the synthetic connecting material (200: 200a, 200b, 200c, 200d, 200e, 200f) used in the present invention.

First, the synthetic connection member 200 will be described based on the material side.

The present invention uses the composite connector 200 of the FRP material in order to synthesize the walls (110, 120) to structurally integrate with each other.

Since the composite connector 200 of the FRP material has a very low thermal conductivity than the steel, even if the walls (110, 120) are connected (bonded) there is an advantage that can minimize the thermal bridge phenomenon.

In addition, the synthetic connecting material 200 of the present invention is to use a reinforcing bar using an epoxy coated. Such a composite connection member 200 has the advantage that it is possible to produce economically while minimizing the thermal bridge phenomenon.

Synthetic connection member 200 in this material aspect will be described in detail below.

Next, look at the composite connecting material 200 on the basis of the shape side as follows.

That is, such a shape side is composed of a synthetic connecting member 200 of a planar shape and a three-dimensional shape, where the meaning of the planar shape means that it extends while forming one plane in the longitudinal direction.

First look at the composite connecting material (200; 200a, 200b, 200c, 200d, 200e) by the planar form.

As shown in FIG. 3a, expansion flanges 210a and 210b are formed at ends, and between the extension flanges 210a and 210b, a body portion 230a having a bar or bar shape having a circular or square cross section is formed. Synthetic reinforcement 200a may be used.

In the case of manufacturing this, for example, first, by using a FRP material to produce a bar (BAR) shaped body portion (230a), and the resin body impregnated a large number of linear FRP fibers 231a in the longitudinal direction of the body portion 230a outer peripheral surface After stacking, additional spiral FRP fibers 232a are laminated on the outer circumferential surface of the straight FRP fibers, and the expansion flanges 210a and 210b may be additionally mounted at the end of the trunk portion 230.

Alternatively, the expansion flanges 210a and 210b may be manufactured by laminating impregnated linear FRP fibers and spiral FRP fibers on the trunk portions formed at both sides thereof.

As described above, the direction in which the FRP fibers are deviated from each other or formed in an orthogonal shape is that the FRP fibers of each layer can secure the load resistance performance in one direction, so that the FRP fibers are stacked in different directions. This is to sufficiently secure the shear resistance performance of 200a.

The expansion flanges 210a and 210b may be formed in various shapes such as a circular shape, and the expansion flanges 210a and 210b may serve to completely fix both sides of the composite connection material inside the walls 110 and 120. .

That is, it is common to use a reinforcing bar in the conventional connecting material, but the reinforcing bar starts from the insulator and extends to the wall to synthesize both walls 110 and 120, but in this form, both walls are not sufficient to structurally integrate completely. This is, after all, nothing more than the binding of both walls and insulation.

Accordingly, the present invention allows one side of the composite connecting member 200a to be completely embedded in one side outer wall 110 to be fixed so that the synthetic connecting member 200a protrudes from the inside of the wall to the outside, and the other side of the other outer wall 120. By embedding and fixing in the interior, it can be said that there is a difference from the arrangement of the connecting material such as conventional reinforcing to sufficiently secure the composite effect of both walls.

In addition, as shown in FIG. 3B, expansion flanges 210a and 210b may be formed on both sides, and a planar synthetic reinforcement 200b may be used between the expansion flanges so as to form a body portion 230b. . This can be said to be manufactured in the form of I-shaped steel or H-shaped steel.

In the case of manufacturing this, the body portion 230a having a final predetermined thickness may be formed by first stacking, for example, using a FRP material in a plate shape, and then stacking a plurality of FRP materials in the plate shape.

The plate-shaped FRP material to be laminated is produced by laminating a plurality of straight FRP fibers (231b) in the longitudinal direction by resin impregnated to laminate a plurality of sheet-shaped body portion, the direction of arrangement of the FRP fibers of each layer is the longitudinal direction of the body portion, The plurality of longitudinal flanges 232b and 233b may be arranged in the longitudinal direction and the vertical direction, and the expansion flanges 210a and 210b may be additionally attached to the end of the body portion 230a.

Alternatively, the expansion flange may be manufactured by stacking the body parts formed on both sides while varying the arrangement of the resin-impregnated FRP fibers as described above.

Also, the direction in which the FRP fibers are shifted or formed in an orthogonal shape is that the FRP fibers in each layer can secure the load resistance performance in one direction, so that the stacking direction of the laminated FRP fibers is different from each other so that the shear resistance of the composite connector is different. The same is true to ensure sufficient performance.

The expansion flanges 210a and 210b may be formed in a rectangular plate shape.

Accordingly, the wall 100 according to FIG. 3B also allows one side of the composite connecting member 200b to be completely embedded in one outer wall to be fixed so that the FRP composite connecting member protrudes from the inside of the wall to the outside, and the other side of the inner connecting wall 200b. The same is true for embedding and fixing.

In addition, the planar composite connecting member 200 of the present invention may be used as a lattice-shaped composite reinforcement (200c) by manufacturing the FRP wire in the form of a lattice, such as wire mesh, as shown in Figure 3c, cut in a horizontal direction or inclined direction. have.

According to the method of manufacturing a composite reinforcement of the lattice form is produced by the method of impregnating and laminating the FRP fibers arranged in the direction orthogonal to each other, this type of FRP wire rods are arranged in both directions, also the shear of the FRP synthetic reinforcement It can be seen that sufficient resistance performance can be obtained.

In the case of the lattice-shaped synthetic reinforcing material (200c) is fixed by embedding both sides in the wall,

Also, one side of the composite connector of the present invention is completely embedded in one outer wall to be fixed so that the FRP composite connector protrudes from the inside of the wall to the outside, and the other side is embedded in and fixed to the inside of the other outer wall. It can be seen that the synthetic effect can be sufficiently secured.

In the following, the case of the composite connecting material in particular by the waveform composite connecting material looks at.

That is, as illustrated in FIG. 4A, a rod-shaped composite wave connecting member 200d having a triangular or trapezoidal shape in the longitudinal direction is formed continuously or spaced apart from each other.

The bent portion (B) is to be formed in advance in the form of the rod-shaped composite connecting material (200d) in advance to be formed naturally, and said bent portion (B) to say that the synthetic connecting material of the present invention is formed in a wave form Can be.

In this case, the corrugated composite reinforcement 200d may also use FRP material or epoxy coated rebar.

For example, the composite composite reinforcing material (200d) of the FRP material is first made of a rod (BAR) body portion 210d of the FRP material, a number of straight FRP fibers in the longitudinal direction of the body portion 220d on the outer peripheral surface of the body portion 210d (220d) The resin is impregnated and laminated, and the spiral FRP fibers 230d may be additionally laminated on the outer surface of the straight FRP fibers.

As described above, the extending directions of the FRP fibers are shifted from each other or formed in an orthogonal shape in order to sufficiently secure the shear resistance performance of the composite connecting material by differently stacking directions of the stacked FRP fibers.

Furthermore, epoxy 240d coated steel (250d) can be used as a corrugated composite reinforcement (200d), and since the reinforcing bars are easy to process, forming bends and impregnating the epoxy coated steel reinforcement in a manner to impregnate the epoxy composite wave 200d can be produced.

In addition, as shown in FIG. 4B, two curved rod-like composite connectors having a triangular or trapezoidal shape are continuously or spaced apart from each other. 200e is used.

In this case, the planar shape is also meant to extend while forming one plane in the longitudinal direction, it characterized in that the two waveform composite connecting material (200d) is formed to overlap each other.

When the two corrugated composite connecting members (200d) are overlapped and formed in this way, the self-strength of the corrugated composite reinforcing material (200e) becomes very large, and the synthesizing effect of both walls is enhanced to provide an effective composite concrete wall. The corrugated composite reinforcement (200e) is also the same can be used for FRP material or epoxy coated rebar.

Next look at the composite connecting material (200; 200f) by the three-dimensional form.

That is, the bent portion (B) including a triangular or trapezoidal shape as shown in FIG. 4C is continuous or spaced apart from each other in the form of a two-sided synthetic connecting member (200d) formed in a standing plane form each other and then the top of the bent portion A three-dimensional waveform composite connecting material 200f, which is inclined to each other and formed into a three-dimensional shape, is used.

Particularly, the reason why the three-dimensional shape is manufactured in this way is that the corrugated composite connecting member 200f acts as a triangular truss member to have more efficient bending moment resistance. The corrugated composite reinforcing member 200f is also made of FRP material or epoxy. It is the same that the coated steel can be used.

Next, look at the action of the composite concrete wall using the synthetic reinforcement. Of course, such a composite concrete wall will be based on the state installed in the final building.

Synthetic concrete wall 100 according to the present invention basically means that the heat insulating material is installed between the concrete wall by the interrupted heat structure, as shown in Figure 1c, means a wall made in a way to synthesize both walls,

The wall 100 according to the present invention is provided with one outer wall 110, the other outer wall 120 and the heat insulating material 130 is made of concrete or reinforced concrete.

In this case, the meaning of the one side and the other side is that the heat insulating material is disposed in the middle and the walls are formed to be spaced apart from each other when the wall is installed on the outside of the building, the wall facing the interior of the building becomes the inner wall, the outer wall is the outer wall Therefore, if the inner wall is referred to as one side of the outer wall is a name concept that the outer wall formed to be spaced apart from the inner wall is the other outer wall.

Accordingly, it can be seen that the one side and the other outer wall (110, 120) is manufactured as a composite concrete wall, and the one made of a member in the form of a panel having a constant cross-sectional area and thickness is used. This is because the wall needs to be manufactured to have a size necessary for the fabrication, transportation and installation of the wall.

For example, each wall has a thickness T in the horizontal direction, a height H in the longitudinal direction, and a length in the longitudinal direction L. FIG.

In this case, the present invention uses the composite connecting material 200 made of FRP material or epoxy coated reinforcing bars to synthesize the walls 110 and 120 structurally integrated with each other.

In particular, the composite connector 200 of the FRP material has a very low thermal conductivity than steel, so even if the walls (110, 120) are connected (bonded) it is possible to minimize the thermal bridge phenomenon,

Epoxy-coated steel can prevent thermal bridges and make economical composite connectors.

Furthermore, a heat insulating material 130 is formed between one side and the other outer wall (110, 120), the heat insulating material 130 may be used in the form of a heat insulating material easy to process, such as styropol, gel insulation like foam concrete May be filled between the walls.

Thus, in the case of using a styropole in the form of a plate, the insulation may be disposed in a space other than the space occupied by the corrugated composite connector, and the insulation of the gel form may be formed by filling the synthetic connector 200 so as to be filled.

Therefore, even when the wall 100 according to the present invention is manufactured in a synthetic type, it can be seen that the thermal bridge phenomenon can be minimized by the synthetic connecting material 200.

In addition, since the composite connecting material according to the present invention has a very high strength in itself, both ends are embedded and fixed in the wall to increase the strength of the wall itself, thereby increasing the mechanical strength of the wall 100. It can be seen that in the wall of the conventional heat dissipation structure, the structure is fundamentally different from the connecting material such as reinforcing bar which functions as a simple shear connecting material.

In addition, in the aspect of the waveform composite connector (200; 200d, 200e, 200f) in the shape of the meaning of the waveform means that a plurality of bent portions in the longitudinal direction are formed continuously or spaced apart from each other. It is possible to improve the rigidity of the composite connector itself by the characteristic features, FRP and epoxy-coated rebar is very effective in improving the bending strength of the wall 100, because its own strength is relatively large.

In addition, since the corrugated composite connection member 200 (200d, 200e, 200f) is installed as if sewing the heat insulating material 130 between both the walls (110, 120), it becomes very efficient in the positioning and integration of both walls and the heat insulating material.

First, the wall 100 using the composite connecting material 200 of the planar shape according to FIGS. 3A, 3B and 3C will be described in detail (it will be described with reference to FIG. 3A).

As shown in the left side of FIG. 5A, the wall of the present invention may be manufactured in a three-unit manner in which a heat insulating material 130 is formed between a pair of walls 110 and 120.

As shown in the right side of FIG. 5A, it can be seen that the wall of the present invention may be manufactured in a 5-unit manner in which a heat insulating material 130 is formed between three walls and intermediate walls 110, 120, and 140, respectively. It can be seen that can be produced in more than five units.

In this case, the planar composite connecting member 200 may be installed in the horizontal direction (T) so that a plurality of spaced apart in the vertical direction (H).

Next, looking at the wall 100 using the waveform composite connecting material 200 of the planar and three-dimensional shape according to Figures 4a, 4b and 4c in detail,

As shown in the left side of FIG. 5B, the wall of the present invention may be manufactured in a three-unit manner in which a heat insulating material 130 is formed between a pair of walls 110 and 120.

5b, it can be seen that the wall of the present invention may be manufactured in a 5-unit manner in which a heat insulating material 130 is formed between the three walls and the intermediate walls 110, 120, and 140, respectively. It can also be seen that it can be manufactured in more ways than a unit.

In addition, in the left view of FIG. 5B, the composite concrete wall 100 having the thickness T in the horizontal direction, the height H in the vertical direction, and the length in the longitudinal direction L may be respectively as shown in FIG. 4A. Waveform composite connector 200 is installed so as to extend in the longitudinal direction (L), it can be seen that a plurality of spaced apart from each other in the longitudinal direction (H).

On the other hand, in the left view of FIG. 5C, each of the composite concrete walls 100 having the thickness T in the horizontal direction, the height H in the longitudinal direction, and the length in the longitudinal direction L is the same as in FIG. 4B. It can be seen that the waveform composite connecting member 200 is installed to extend in the longitudinal direction (H), a plurality of spaced apart from each other in the longitudinal direction (L).

In particular, it can be seen that the waveform composite connecting member 200 as shown in FIG. 4B may be installed in the center and the right side of FIG. 5B.

In addition, in the case of Figure 5d it can be seen that the three-dimensional waveform composite connecting member 200 as shown in Figure 4c that can be installed to extend in the horizontal and vertical directions, respectively.

These various embodiments are ultimately due to the difference in the installation direction of the composite connecting member 200. In particular, the planar or three-dimensional waveform composite connecting member has a bent portion, so that it is continuous in the longitudinal direction as a whole, so Can be adjusted.

In addition, the wall 100 according to the present invention has 50% to 70% of the bending moment resistance due to the increased moment arm length by the corrugated composite connector in comparison with the non-synthetic concrete wall which does not synthesize the walls to prevent the thermal bridge phenomenon. It can be seen that it can be increased by more than%.

That is, in the case of the non-synthetic concrete wall (C), as shown in FIG. 6, since only the heat insulating material is disposed between the two walls and the composite connecting material is not provided, the two walls are not structurally integrated with each other.

The bending moment acting on the wall has a small resistance to the bending moment because its moment arm length (d1) is smaller than the thickness of each wall.

Since the bending moment acting on the composite concrete wall 100 according to the present invention is structurally connected to both walls by being integrated, the moment arm length d2 may extend from one side wall surface to the reinforcing bar position of the opposite wall. It can be seen that the resistance against the bending moment is greatly improved.

Thus, the wall 100 according to the present invention can be seen that it is possible to minimize the thermal conductivity while producing a composite type, and the moment arm length for the working load can be increased compared to the walls made of non-synthetic type wall It can be seen that it can significantly improve the resistance performance to the bending moment acting on.

Next, look at the manufacturing method of the composite concrete wall using the half-wave composite connector of the present invention.

The half composite concrete wall 100b may be manufactured in the field without forming the other side wall at the factory as compared with the full composite concrete wall 100a.

That is, the half-synthetic concrete wall 100 forms a wave composite composite material and insulation on one of the walls in the factory, and the other wall to form the final composite concrete wall 100 by concrete pouring by the formwork at the site Completely installed on the outer wall of the building.

Thus, an example of the method of manufacturing the half-composite concrete wall 100b will be described based on the waveform composite connecting member 200 shown in FIGS. 3A and 4A.

First, a case of using the waveform synthesis connector 200 shown in FIG. 3A will be described.

That is, as shown in FIG. 7a, the concrete 410 is poured into the wall formwork 310 to form one outer wall 110, and the one end a is embedded in the formwork from the inside of the wall. And, the other end portion (b) is set together with the composite connecting material 200 so as to protrude outward of one wall.

That is, the wall formwork 310 may be installed so as to be lying on the floor, it is possible to use steel formwork. The thickness of the formwork may be adjusted to match the wall thickness, and the overall shape may be manufactured so that the wall can be formed in the form of a panel.

Inside the wall formwork 310, for example, reinforcing bars or FRP reinforcing bars (other homogeneous materials are possible) are pre-arranged, and the wall 100 is made of concrete.

After setting the reinforcing bar and the composite connecting material 200 in the formwork 310 as described above, the concrete 410 is poured first, so that the synthetic connecting material 200 can be fixedly installed and poured and cured concrete. It can be seen that the synthetic reinforcement 200 of the present invention to protrude to the upper surface.

At this time, the arrangement of the waveform composite connecting member 200 is installed so that a plurality of longitudinal or spaced apart in the longitudinal direction while extending the longitudinal composite waveform composite connector 200 as shown in Figure 3a, 3b and 3c, or To extend in the longitudinal direction, it may be installed so that a plurality of spaced apart in the longitudinal direction.

Next, as shown in FIG. 7B, a heat insulating material 130 is formed between the top surface of the poured concrete 410 and the FRP composite connecting material.

As the heat insulator 130, a heat insulator is used rather than styropole. In particular, the heat insulating material of the gel form will be filled between the upper surface of the concrete 410 for the wall and the FRP composite connecting material is filled with a form or the like to be cured.

The mold for the final wall 310 is demolded to produce a half composite concrete wall 100.

Next, a case of using the waveform synthesis connecting member 200 according to FIG. 4A will be described.

That is, as shown in FIG. 8a, the concrete 410 is poured into the outer wall formwork 310 to form one outer wall 110, and the waveform is synthesized so as to protrude in the longitudinal or longitudinal direction from the inner side of the outer wall to the outside. The connecting member 200 is set together. (The composite connecting member 200 is based on the waveform composite connecting member 200a of FIG. 4A.)

That is, the wall formwork 310 may be installed so as to be lying on the floor, it is possible to use steel formwork. The thickness of the formwork may be adjusted to match the wall thickness, and the overall shape may be manufactured so that the wall can be formed in the form of a panel.

Inside the wall formwork 310, for example, the reinforcing wall for reinforcement in advance and it can be seen that the wall 100 is made of reinforced concrete.

After setting the reinforcing rod and corrugated composite connecting member 200 together in the form 310 as described above, the concrete 410 is poured first, so that the corrugated composite connecting member 200 can be fixedly installed, and then cured. It can be seen that the composite stiffener 200 of the present invention protrudes from the inside of the concrete 410 to the upper surface.

At this time, the arrangement of the waveform composite connecting member 200 is installed so that a plurality of longitudinal or spaced apart in the longitudinal direction while extending the longitudinal composite waveform composite connector 200 as shown in Figure 4a, 4b and 4c, or To extend in the longitudinal direction, it may be installed so that a plurality of spaced apart in the longitudinal direction.

Next, as shown in FIG. 8b, the insulation 130 is formed between the upper surface of the poured concrete 410 and the FRP composite connector.

As the heat insulating material 130, it is preferable to use a heat insulating material in a gel form rather than styropol. This is because in the case of the half-composite concrete wall 100b, the heat insulating material must be exposed to the outside to remain integrally attached to the concrete.

In particular, the heat insulating material of the gel form will be filled between the upper surface of the concrete 410 for the wall and the FRP composite connecting material is filled with a form or the like to be cured.

The mold for the final wall 310 is demolded to produce a half composite concrete wall 100.

Next, as seen in the interior of the building as shown in Figure 2b it can be seen that the half-synthesized concrete wall 100 is a waveform composite connecting member 200 is exposed. Accordingly, the present invention is to install the formwork 320 for forming the final other side wall 120 of the composite concrete wall (100).

Such formwork 320 allows the corrugated composite connecting material 200 to be embedded in the slab 30, while the internal reinforcing bars are also reinforced inside the formwork 320, and the concrete is poured into the formwork 320 to form a final composite. The concrete wall 100 is completed.

Therefore, when the composite concrete wall 100 is completed in the final building, the form 320 is removed as shown in FIG. 2C to complete the composite concrete wall 100 of the building exterior wall. In the final state, the final construction state of the composite concrete wall manufactured in the factory is the same,

Since the half composite concrete wall is not large in weight, when it is installed in a large size, it is possible to sufficiently solve the disadvantages due to work such as formwork 320 and concrete pouring.

At this time, as described above, the half composite concrete wall 100 is installed to be connected to the slab 30. The slab 30 is installed by the cast-in-place concrete, and then the half composite concrete wall 100 is installed. However, in the case of the slab by the in-site casting it is preferable to extend the reinforcement of the internal reinforcement of the inside of the slab 30 to the inside of the other wall 120 to be connected to the reinforcement of the inside of the other wall.
