BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a process diagram of a method of manufacturing a dual precast member.
8 is a side view of the FRP connecting member.
9 and 10 are perspective views of the supporting member.
11 is a sectional view of the prefabricated house.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1 and subsequent drawings, the dual precast member 100 according to the present invention basically comprises a first member 110 formed in a plate structure by concrete embedded with a steel frame assembly 111; A second member 120 formed in a plate structure by concrete and spaced apart from the first member 110; And an FRP connecting member 130 having both ends embedded in the first member 110 and the second member 120 so as to connect the first member 110 and the second member 120 7).

Since the FRP material of the FRP connecting member 130 has a high strength and a very low thermal conductivity, the FRP connecting member 130 is formed of a material having a high rigidity, Heat and noise can be effectively prevented from being transmitted to the second member 120.

The method of manufacturing the dual precast member 100 according to the present invention is performed by the following process.

A supporting member 140 detachably coupling the FRP connecting member 130 is prepared and a supporting member 140 is installed on the bottom plate of the first molding 10 (Fig. 1).

The reinforcing bar assembly 111 is installed on the upper part of the support member 140 (FIG. 2).

The FRP connecting member 130 is installed on the supporting member 140 (Fig. 3).

The support member 140 and the reinforcing bar assembly 111 are buried and the first member 110 is formed by placing the concrete in the first formwork 10 so that the end of the FRP connecting member 130 is exposed upwardly 4).

The first die 10 is turned upside down on the second die 20 so that the end of the FRP connecting member 130 faces downward and is positioned in the inner area of the second die 20 (Figure 6) .

The second member 120 is formed by pouring concrete into the second mold 20 so that the end of the FRP connecting member 130 is embedded (FIG. 6).

The first mold 10 and the second mold 20 are demolded (Fig. 7).

The support member 140 is separated from the first member 110, and the separated site is filled with filler and closed.

That is, this is an efficient manufacturing method for constructing a structure in which the first member 110 and the second member 120 made of concrete are coupled with each other with the FRP connecting member 130 interposed therebetween, .

The FRP connecting member 130 includes a bar-shaped main body; An attachment (131) formed at both ends of the body; A plurality of projections 132 protruding outwardly along the longitudinal direction on the outer circumferential surface of the main body can be easily assembled to the support member 140 and the reinforcing bar assembly 111, (Fig. 8). In addition, it is possible to perform stable settlement with concrete by using the above-mentioned method.

When the protruding portion 132 has a ring-like structure, the above effect can be further increased.

When the projecting portion 132a of the plurality of projecting portions 132 that is in contact with the surface of the first member 110 or the second member 120 is formed thicker than the other projecting portion 132, And the embedding depth of the FRP connecting member 130 can be easily confirmed, which is advantageous in terms of workability.

The supporting member 140 is configured to detachably connect the FRP connecting member 130 to allow the FRP connecting member 130 to be disposed at a predetermined position during the pouring of the concrete and to remove the FRP connecting member 130 after the concrete curing do.

For this, a body 141 formed by a flexible material and having a cutout 142 for mounting an end of the FRP connection member 130 in the core part is formed; And a form fitting portion 143 formed on the body portion 141 so as to be detachably coupled to the first formwork 10 (Fig. 9).

That is, when the body portion 141 is formed of a rubber material or the like and the cut portion 142 is formed in the body portion 141 in a "+" shape or the like, the FRP connecting member 130 is cut into the cut portion 142 As shown in Fig.

When the supporting member 140 is provided with the supporting plate 144 formed with the form fitting part 143 at the lower part and the body part 141 is formed in a hollowed hemispherical structure at the upper part of the supporting plate 144, The effect can be obtained more stably (Fig. 10).

The double precast member 100 according to the present invention can be applied to a wall-mounted structure, a slab, or the like in a prefabricated house.

When the double precast member 100 is installed as a wall, the first member 110 is disposed toward the inside of the building and the second member 120 is disposed toward the outside of the building, thereby obtaining an effective heat insulating structure .

When the dual precast member 100 is installed as a slab, the first member 110 is disposed to face upward and the second member 120 is disposed to face downward, (Fig. 11).

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It is to be understood that both the technical idea and the technical spirit of the invention are included in the scope of the present invention.
