The composite panel 200 includes a connecting ring 70 for connecting to the lifting device 300 and a supporting member 75 for connecting to the inclined support 80. Preferably, the connecting ring 70 and the supporting member 75 are installed in the projection 66 formed to protrude on the rear surface of the thin panel 65.

Next, a process of constructing the outer wall by the built-up method using the composite panel 200 will be described with reference to FIGS. 19 and 20. Composite panel 200 is to use the shear connector 40 of FIG.

First, the composite panel 200 is manufactured. The composite panel 200 may be manufactured by a factory manufacturing method or a field manufacturing method. There is only a difference between a factory manufacturing method and an on-site manufacturing method whether the bed is in a factory or on site.

After manufacturing the formwork, the reinforcing bar 60 is placed in the formwork. Meanwhile, the shear connector 40 is installed on the metal vertical member or the horizontal member, and the vertical member 21 and the horizontal member 25 are combined to manufacture the metal skeleton panel 20. Subsequently, the reinforcing bar 60 installed in the formwork is connected with the shear connector 40 and the concrete-based material is poured. Concrete-based material is preferably cast so that the flange 23 is exposed to the outside, the reason has been described above.

The manufactured composite panel 200 is moved by a lifting device 300, for example, a crane, and is erected on a completed floor of the building. The connecting ring 70 of the composite panel 200 is used to connect the lifting device 300 and the composite panel 200 to move, and the support member 75 moves the composite panel 200 to the inclined support 80. It is used to support and stand on the floor.

Since the composite panel 200 is relatively lighter than the conventional precast panel, the composite panel 200 may be manufactured to a larger size when using the same lifting apparatus 300. In addition, the outer wall corresponding to a width of up to about 10m and the height of a middle-rise building, which is about 4-5 floors, can be manufactured and constructed with a single composite panel 200. The advantage is that it can be minimized.

In this way, the composite panel 200 is used to preferentially make the remaining outer wall except for one side of the outer wall of the building. 20 shows that three surfaces are preferentially made among the four surfaces of the outer wall of the building.

Then, the composite panel 200 is fixed using an anchor (not shown). The anchor is embedded in the bottom in advance and then inserted into the through hole (not shown) of the lowermost horizontal member 25.

Alternatively, the anchor may be fixed to the lowermost horizontal member 25. That is, the bottom surface may be drilled using a drill and an adhesive anchor may be installed, the bottom surface may be drilled with a small hole, and the anchor may be typed, or the anchor may be directly typed on the bottom surface.

When the anchor is constructed, a metal plate (not shown) having a washer function is installed between the anchor head and the horizontal member 25 so that the compressive force of the anchor can be transmitted to the horizontal member 25.

After the anchor construction is completed, the main structure (not shown) is installed in the interior surrounded by the composite panel 200 and combines the main structure and the composite panel 200.

When the composite panel 200 is installed in close contact with the steel pillars or cheolgolbo of the main structure, the composite panel 200 and the main structure can be coupled by direct welding. In addition, the combination of the composite panel 200 and the main structure may be made by a bonding bolt method or an anchor bolt method used in the curtain wall method. Bonding bolt method is a method of integrating the composite panel 200 and the main structure with a variety of connecting hardware and long binding material, anchor bolt method is to combine the composite panel 200 after the purchase of the anchor bolt in the concrete main structure That's the way.

When the coupling of the main structure and the composite panel 200 is completed, the composite panel 200 is installed on one side where the composite panel 200 is not installed. Installation of the composite panel 200 on one side may be made by a built-up method or a cladding method.

Meanwhile, a process of constructing the outer wall by the cladding method using the composite panel 200 will be described with reference to FIGS. 19, 21, and 22.

In the cladding method, the main structures 400 and 410 are first constructed, and then the composite panel 200 is coupled to the main structures 400 and 410. The manufacturing process of the composite panel 200 has been described above.

As shown in FIG. 21, when the above method is applied to a low-rise building, the large composite panel 200 is continuously installed on the main structure 400 to complete the outer wall. On the other hand, as shown in Figure 22, when the method is applied to a high-rise building, the composite panel 200 corresponding to the height of the floor is continuously installed on the main structure 410 to complete the outer wall.

In the cladding method, the combination of the composite panel 200 and the main structures 400 and 410 may apply a method of combining the composite panel 200 and the main structure in the above-described built-up method.
