At this time, the neighboring double wall PCs 100 are arranged in parallel on a virtual line as shown in FIG. 1 and FIG. That is, the angle formed by one of the double wall PC 100-1 and the other double wall PC 100-2 is 180 °.
When the double wallpapers 100 are arranged in the horizontal direction, the connecting and joining units 200 and 200 'are inserted into the spaced spaces of neighboring double wall PCs 100. The connecting joint units 200 and 200 'are lowered to the upper side of the double wall PCs 100 and inserted into the spaced spaces of the double wall PCs 100. The connecting joint units 200 and 200 'are previously manufactured in a modularized state and transferred to the construction site. Thus, the connecting joint units 200 and 200' can be inserted only by lowering the double wall PCs 100 from the upper side to the lower side.
When the connecting and connecting units 200 and 200 'are inserted into the spacing spaces of the double wall PCs 100, the connecting and connecting unit 200 according to an embodiment of the present invention includes the adjacent connecting units 200 and 200' And is inserted into the spacing space of one of the double wallpapers 100 and the spacing space of one of the double wallpapers 100 at the same time.
3, the fastening member 260 of the connection and connection unit 200 'is connected to the adjacent double wall PCs 100' To be spaced apart from the adjacent double wall PCs 100 so as to pass between the adjacent double wall PCs 100 '.
The coupling nuts 263 and 265 of the fastening member 260 are rotated so that the first and second wafers 110 and 110 are inserted into the spacing spaces of the adjacent double wallets 100, And the second month PC 130 are tightened.
When the concrete is poured into the spaced apart spaces of the double wall PCs 100 after the connecting and connecting unit 200 'is inserted into the double wall PC 100 adjacent to the fastening member 260, Thereby preventing the first month PC 110 and the second month PC 130 from being opened.
When the connecting joint units 200 and 200 'are inserted into the spacing spaces of the neighboring double wall PCs 100 and between the first wall plates 110 of neighboring double wall PCs 100, And the shielding member 10 is sandwiched between the second month PCs 130. As shown in FIG. 1, in an embodiment of the present invention, the shield member 10 is formed to have a length corresponding to the height of the double wall PCs 100, and between the first wall PCs 110, And are sandwiched between the second month PCs 130.
However, as shown in FIG. 3, in another embodiment of the present invention, the fastening members 260 are spaced along the height direction of the double wall PCs 100, so that the fastening members 260 are spaced apart from each other The shielding member 10 is formed so as to correspond to the shielding member 260 so that the shielding member 260 is disposed between the first wallcapes 110 and between the second wallcapes 130. [ 10 are inserted. The shielding member 10 prevents concrete from leaking between adjacent double wall PCs 100 when the concrete is poured into a spaced space of the double wall PCs 100 in a process to be described later.
Next, the concrete is poured into the spaced apart spaces of the double wall PCs 100. The poured concrete is also bonded to the connection and connection units 200 and 200 and is also bonded to one of the double wall PC 100-1 and the other double wall PC 100-2. That is, the neighboring double wall PCs 100 are not only joined by the laid concrete but also joined by the connecting and joining units 200 and 200 'inserted into the spacing spaces of the neighboring double wall PCs 100, The fixing force is further improved.
3, when the poured concrete is cured in the spaced apart spaces of the double wallets 100, the fastening nuts 263 and 265 of the fastening member 260 are removed, A part of the second reinforcing bars 261 protruding outside of the first reinforcing bars 100 is also cut and removed.
9, the method of joining double wall PCs according to another embodiment of the present invention includes steps of fabricating double wall PCs 100 '(step S205), moving the double wall PCs 100' (Step S215) of inserting the connection joint unit 300 into the spacing space of the double wall PCs 100 and placing the concrete in the neighboring double wall PC 100 ' (Step S220). The step of fabricating the double wall paper 100 'is the same as the step of fabricating the double wall paper 100 in the above-mentioned embodiment, and a description thereof will be omitted.
In the step of arranging the double wallpapers 100 'in the horizontal direction (step S210), when the double wallpapers 100' are arranged in the horizontal direction, as shown in FIG. 5, the double wallpapers 100 ' 100 'are arranged orthogonally, that is, the neighboring double wall PCs 100' at an angle of 90 degrees. After the double wallpapers 100 'are arranged orthogonally, the connecting and joining units 300 are inserted into the spacing spaces of the neighboring double wallets 100' at the same time, 300 are inserted so as to pass between the adjacent double wall PCs 100 '. The fastening member 340 is fastened to both sides of the fastening rod 341 by fastening nuts 343 and 345 in the same manner as the tightening member 260 described above, The first month PC '110' and the second month PC '130' are not opened.
When the connection and connection unit 300 is inserted, concrete is poured into the spacing spaces of the double wall PCs 100 'to join the double wall PCs 100'. Of the double wall PCs 100 'by the tightening member 340 even if concrete is poured into the spacing spaces of the double wallets 100' Is prevented.
As described above, the neighboring double wallets 100 'are joined by the poured concrete, but the concrete may be adhered not only to the neighboring double wallets 100' but also to the connecting and joining unit 300 , The bonding fixing force of the adjacent double wall paper 100 'is improved, and an effect of more firmly bonding can be expected. When the adjacent double wallets 100 are joined to each other, the reinforcing rods 341 protruding outward from the fastening nuts 343 and 345 of the fastening member 340 and the double wallets 100 ' Some are cut and removed and then finished.
While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
