The holes 731 may serve as a shear connector embedded in the slab concrete.

Since the bottom plate 71 of the beam can be seated on the upper portion of the receiving plate 30 protruding outward than the engaging plate 12 when the beam 7 is joined to the beam connecting bracket 1 , A difference in thickness may occur in the upper portion of the receiving plate 30 between the engaging plates 12 by the thickness of the bottom plate 71. An auxiliary plate 40 of a certain thickness is additionally installed on the upper portion of the receiving plate 30 between the adjacent connecting plates 12 between the pair of bonding modules 10 of the bracket 1 for beam- So that the difference in thickness from the bottom plate 71 can be overcome.

The coupling of the beam connecting bracket 1 and the beam 7 is carried out by connecting the coupling plate 12 of the beam connecting bracket 1 and the side wall 72 of the beam 7 to the joint plate 8, And the like can be coupled by various known methods such as bolts and the like.

8 is a perspective view showing a modified example of a beam used in the column-to-beam connection structure using the beam-splicing bracket of the present invention.

The shear restraint plate 73 of the beam 7 can be combined with one sheathed shear restraint plate as shown in FIGS. 5 and 6, A plurality of spacers may be provided.

At least one compression stiffener 74 connecting the shear restraint plates may be additionally provided when a plurality of shear restraint plates 73 are spaced apart at predetermined intervals, And may be joined to the upper surface (outer side) or the lower surface (inner side) of the shear restraining plate by various known methods such as welding.
