The blocking plate 26 to close the bracket through-hole 115 in the position will have to be coupled.

16 is a perspective view showing another embodiment of the present invention pillar bracket, and FIG. 17 is a plan sectional view of the embodiment of FIG.

16 and 17, the pillar bracket of the present invention has a plurality of shaped steel material 11 is disposed on each corner of the column so as to be spaced apart from the column surface by a predetermined distance and the concrete 10 is filled with concrete 10 inside ) And a cross bracket (2) installed in the panel zone of the steel composite concrete column (1) to couple the beam (3) to the pillar, and the cross bracket (2) by interconnecting the adjacent section steel And a lower pedestal 12 and an upper pedestal 13, which are coupled to and supported at the lower and upper portions thereof, respectively, and the cross bracket 2 is disposed at the center of the pillar panel zone. The main bracket 21 is coupled to both sides of the phosphorus connecting member 23 and the connecting member 23 and protrudes to the outside of the pillar, and the lower and upper portions are coupled to the lower pedestal 12 and the upper pedestal 13, respectively. The main bracket 21 and They are bonded to each other both side surfaces and the upper protrusion and the lower pole to the outside of the connection member 23 so that the school song can be configured as a sub-bracket 22 to be coupled to each of the lower bases 12 and the upper bases (13).

The embodiment of the pillar bracket shown in FIGS. 16 and 17 is more suitable for an intermediate moment frame (IMF).

Figure 16 (b) is a perspective view showing in detail the remaining portion of the pillar bracket shown in Figure 16 (a) except for the steel, lower pedestal 12 and the upper pedestal (13).

As shown in FIG. 18, at least one or more of both ends of the main bracket 21 and the sub bracket 22 are formed to be inclined at an acute angle, and the joining plates 24 are respectively coupled to the inclined ends. The bonding plate 24 may be configured to protrude to the top of the upper flange.

The joining plate 24 may be coupled to both inclined ends or one of the inclined ends of the main bracket 21 and the sub bracket 22.

At this time, the end of the beam (3) also comprises an inclined surface so as to correspond to the bonding plate 24 of the main bracket 21 or the sub-bracket 22, the upper end of the beam (3) to the inclined end of the beam (3) It can be coupled to the bonding plate 34 to protrude a certain length.

The facing joining

plates

24 and 34 are fastened with tension bolts at the upper and lower flanges of the beam 3, respectively, to couple the bracket and the beam 3 to each other. When the lateral force is applied, tensile force may be generated in the lower portion of the

bonding plates

24 and 34. Therefore, when the lateral force is applied, a tension bolt for lateral force resistance is applied to the lower portion of the

bonding plates

24 and 34 which protrude a certain length to the lower end of the beam 3. The other part can be tightened preliminarily if necessary.

Since the surface where the main bracket 21 or the sub-bracket 22 and the beam 3 meet each other forms an oblique line, the shear force is well transmitted at the joint surface, and the number of bolts required at the time of joining because the bolt does not have to bear the shear force. Can be drastically reduced, so it is excellent in economy and construction.

In addition, since the

bonding plates

24 and 34 facing each other are completely in contact with each other, precise construction is possible without additional reinforcing plates.

A portion of the

joint plates

24 and 34 protruding to the top of the upper flange may later be buried in the slab concrete to serve as a shear connector.

Of course, when the bonding plate 24 is pre-coupled to the main bracket 21 or the sub bracket 22, the sub bracket 22 passes through the through hole 211 of the main bracket 21 so as to pass well. It should be formed smaller than the ball (211). Similarly, when the steel frame portion 11 is a steel tube, the joining plate 24 is smaller than the bracket through hole 115 so that the main bracket 21 or the sub bracket 22 can pass through the bracket through hole 115 well. It must be formed.

A pair of guide portions 25 may protrude from the front lower portion of the bonding plate 24 coupled to the main bracket 21 or the sub bracket 22 to be spaced apart from each other. At this time, the bottom of both sides of the bonding plate 34 coupled to the end of the beam 3 can form a chamfer so that the lower end of the bonding plate 34 of the beam 3 is inserted between the pair of guide portions 25. have.

The guide portion 25 and the chamfer are for accurately guiding the joining position of the main bracket 21 or the sub bracket 22 and the beam 3 at the time of construction, the beam 3 is left and right by the guide portion 25 It is possible to prevent the departure to both sides and to maintain the horizontal when moving the beam (3). The chamfered portion is caught in the upper portion of the guide portion 25 and the position of the beam 3 is fixed.

The guide portion 25 may be constituted by a bolt member that is coupled to the rear surface of the joining plate 24 and a pipe member that is threaded therein in a tubular shape and screwed to the protruding portion of the bolt member.

On the other hand, when the inclined surface is formed only at one end of the main bracket 21 or the sub-bracket 22, the other end of the main bracket 21 or the sub-bracket 22 of the main bracket 21 or the sub-bracket 22 It is possible to combine the bonding plate 24 in the vertical direction protruding to the upper flange (Fig. 8, 14, 15, etc.).

This eliminates the need for a separate welding operation in the field, and the TSC steel beam which can be integrated with the slab by filling the inside of the beam formed by bending the steel sheet to open the upper portion as shown in FIG. 10-0430317, etc.) can also be used as a beam.

Bonding plate 24 coupled to the other vertical end of the main bracket 21 or the sub-bracket 22 can also be combined with the bonding plate 34 of the beam 3 using a tension bolt, in this case conventional plate It is possible to reduce the number of bolts than the coupling by.

In addition, when the inclined surface is formed only at one end of the main bracket 21 or the sub-bracket 22, as shown in FIG. 14, the support plate 27 is provided at the lower end of the other end of the main bracket 21 or the sub-bracket 22. Can be combined. The support plate 27 fixes the position of the beam 3 by mounting the beam 3 on the top.

Instead of the support plate 27, as shown in FIG. 18, a pair of guide portions 25 are formed on the joining plate 24 coupled to the ends of the main bracket 21 or the sub bracket 22, and the beam 3 It is also possible to fix the position of the beam (3) by forming chamfers on both sides of the lower end of the bonding plate 34 coupled to the end of the.

Figure 19 is a side cross-sectional view showing a process in which the beam is bonded to the pillar using the pillar bracket of the present invention.

In (a) of FIG. 19, a vertical joining plate and an inclined joining plate 24 are coupled to ends of the main bracket 21 to which the beams 3 are coupled, and a pair of guides each on the front surface of each joining plate ( 25) was formed. The beam 3 positioned between adjacent pillars has a chamfered portion of the joining plate coupled to both ends thereof, which is fixed to the upper portion of the guide 25.
