That is, instead of placing the entire slab at a time, the temporary slab 200 and the main body slab are separately laid so that the temporary slab 200 is utilized as a supporting structure for installing the main body slab 300.

Hereinafter, reference is made to the thickness of the pavement of the pavement slab 200 and the construction necessary for the structurally stable composition of the pavement slab 200 and the body slab 300.

A part of the structure of the lower structure 100 is formed into a composite structure for the structurally stable synthesis of the temporary slab 200 and the main body slab 300.

That is, the lower structure 100 includes a column 110, a steel composite member 120 having both ends connected to the column 110, and a deck plate 130 mounted on the steel composite member 120 (FIG. 4) The steel composite beam 120 includes a lower steel plate 121, a first angle 122 coupled to the upper surface of the lower steel plate 121, a second angle 123 coupled to the upper portion of the first angle 122, And a reticle member 124 connecting the first angle 122 and the second angle 123 (FIG. 3).

In this case, it is preferable that the temporary slab 200 in the first step S100 is installed lower than the upper surface of the second angle 123 and the deck plate 130.

The lower or entire portions of the lower steel plate 121, the first angle 122 and the resty member 124 of the steel composite member 120 are embedded in the temporary slab 200, The upper portion of the first slab 124 and the second angle 123 are embedded in the main body slab 300.

Therefore, the steel composite beam 120 serves as a composite member of the temporary slab 200 and the main body slab 300.

The lower structure 100 according to an embodiment of the present invention is coupled to an upper portion of the upper side 131 and an upper portion of the upper portion 131 coupled to the upper surface of the deck plate 130, And may further include a cast iron rope 400 (Fig. 4). It is preferable that the cast iron 400 is embedded in the main body slab 300.

In this case, the structural stability of the transfer mat can be ensured and the composite force of the slab 200 and the main body slab 300 can be increased.

The lower surface of the temporary slab 200 and the lower surface of the main body slab 300 in the formation of the temporary slab 200 and the main body slab 300 according to an embodiment of the present invention may include a deck plate 130 and a lower steel plate 121 And the side surfaces of the temporary slab 200 and the main body slab 300 are formed by using the gantry 500. In this case,

That is, the temporary slab 200 and the main body slab 300 are formed by using the gantry 500 used for the reference layer construction, without using a separate form to form the transfer mat.

As a result, it is possible to eliminate the use of a separate member, thereby reducing the cost of the member, lowering the difficulty of site construction, and quickly performing the construction progress.

According to the present invention, since the gantry 500 can be directly applied to the reference layer construction of the wall-like structure 2 formed on the transfer mat after completion of the construction of the transfer mat, the efficiency of the work performance can be obtained .

In addition, it is also possible to install the deck plate 130 vertically to replace the gantry 500.

According to an embodiment of the present invention, in forming the side surfaces of the temporary slab 200 and the main body slab 300 using the gantry 500, the gantry fixing portion 600 may be provided to fix the position of the gantry 500, Can be formed on the upper surface of the temporary slab 200.

More specifically, when the temporary slab 200 is installed and cured, a ring-shaped fixed gantry 600 is installed on the upper surface of the temporary slab 200 at a predetermined distance from a position where the gantry is to be installed, After the curing is completed, it is possible to fix the gantry 500 to the correct position by connecting and fixing the gantry 500 and the gantry fixing part 600 using a wire member.

According to one embodiment of the present invention, in the formation of the temporary slab 200 and the main body slab 300, the deck plate 130 and the stopper (not shown) coupled to the gantry 500 510) (Fig. 6).

The stopper 510 is coupled along the direction of the gang 500 and the deck plate 130 and is bent at an angle depending on the angle formed by the gang 500 and the deck plate 130, .

In this case, the stopper 510 and the gantry 500 are bolted to each other to release the bolt connection after the curing of the temporary slab 200 and the main body slab 300 so that the gantry 500 can be separated desirable.
