Next, the second to fifth embodiments of the present invention will be described with reference to FIGS. 6A to 6D. In addition, another structure of the insertion member will be described with reference to FIGS. 7A and 7B. 6A is a schematic view showing a brace connection structure according to a second embodiment of the present invention, and FIGS. 6B to 6D are schematic views showing third to fifth embodiments modified from the embodiment shown in FIG. 6A, respectively. . 7A and 7B are perspective views showing another example of the insertion member.

When the second embodiment shown in Fig. 6A is compared with the first embodiment, the other components are the same except that the channel of the second embodiment is positioned horizontally. Therefore, the same reference numerals are given to the same components in the first embodiment, and description thereof will be omitted.

First, as shown in Figure 6a, the connecting member 120 with the rail member 125 is fixed to the end of the H beam 110, the rail member 125 is the upper and lower flanges 110F of the H beam 110 Respectively). Therefore, the channel 127 formed when the two connecting members 120 are in contact with each other is located in the horizontal direction.

In this way, the insertion member 130 is inserted into the channel 127 located horizontally, and the bolt 141 is inserted through and fastened and fixed with the nut 142.

As described above, in the second embodiment, since the channel 127 is formed in the horizontal direction, the insertion member 130 may be located inside the channel 127 even if the insertion member 130 does not have the locking plate 137. However, in order to easily adjust the insertion depth of the insertion member 130, the locking plate 137 may be continuously provided.

As in the second embodiment, in the case of the structure to insert the insertion member 130 in the horizontal direction, the rail member 125 of the connecting member 120 is located on the flange of the H-beam (110). Therefore, since the rail member 125 of the connecting member 120 is supported by the flange of the beam 110, its rigidity is further increased, and thus, there is an advantage that a large compressive strength can be exerted.

According to this structure, the insertion member 130 is easily inserted. Although not corresponding to the drawings, the width of the rail member 125 is also increased according to the tapered shape of the insertion member 130. The rest of the structure is the same as in the second embodiment of Fig. 6A.

Configuring the insertion member 130 in a tapered shape as in the fourth embodiment may be applicable to the case in which the insertion member 130 is vertically inserted as in the first embodiment shown in FIG. 4.

The fifth embodiment shown in FIG. 6D is also a modification of the second embodiment, in which the rail member 125 is formed in two pairs, and the insertion member 130 is separated into two accordingly. As such, when the insertion member 130 is separated into two narrow widths, the weight of the insertion member 130 is reduced to facilitate the operation. If the height of the H beam 110 is allowed, the rail member 125 may be formed in a plurality of pairs of two or more pairs, and the insertion member 130 may also be manufactured in a number corresponding thereto.

As in the fifth embodiment shown in FIG. 6D, a configuration in which the rail members 125 are formed in a plurality of pairs and correspondingly, the plurality of insertion members 130 is formed, provided that the width of the H beam 110 is allowed. The same applies to the case in which the insertion member 130 is vertically inserted as in the first embodiment illustrated in FIG. 4.

7A and 7B illustrate an example in which the insertion member 130 mentioned in the first and second embodiments can be used instead.

As shown in FIG. 7A, a handle 138 is formed at one end of the insertion member 130 in the direction in which the insertion member 130 is inserted into the channel 127 to facilitate the transfer of the insertion member 130. And, as shown in Figure 7b, to reduce the weight of the insertion member 130 can be formed hollow 139 in the fixing member 135.

[Example 6]

8 is a schematic diagram of a sixth embodiment of the present invention. In the sixth embodiment illustrated in FIG. 8, the one side connecting member 120 provided with the rail member 125 is fixed to the end of one H beam 110 like the other embodiments described above, but the other H beam ( 110, the connection member 120 is not installed at the end, the insertion member 130 is directly fixed.

That is, instead of installing the connecting plate 121 of the connecting member 120 at the end of the other H beam 110, one surface of the fastening plate 131 of the insertion member 130 is directly welded. The other fastening plate 131 of the insertion member 130 is inserted into the channel formed by the connecting plate 121 and the rail member 125 of the connecting member 120 is connected to both the H beam 110 and bolts The configuration of the fastening or the like is the same as in the other embodiments.

In the case of the sixth embodiment, since the insertion member 130 is already provided on one side H beam 110, there is an advantage that does not need to carry the heavy insertion member 130 separately.

As described in detail above, the brace connection structure of the present invention is welded and fixed to the beam in the field, by fastening and fastening with a bolt in the state connecting the two connecting members with the insertion member, it is possible to easily produce a brace of the desired length . Therefore, there is an advantage in that it is possible to manufacture a brace much easier than the work of fastening the bolt after the through-hole in the beam and the connecting piece as in the prior art.

In addition, the connection structure of the support beam of the present invention transmits the compressive force received by the H beam to the other H beam connected through the connection member and the insertion member fixed to the end of the support beam. In the conventional buttresses, the area in contact with each other is only the cross-sectional area of the buttresses, but in the present invention, since the rail member is in contact with the connecting plate and the insertion member, the area for transmitting force is larger than that of the conventional buttresses. Therefore, by distributing and transmitting the transmitted force, it is possible to prevent the buckling of the joint of the crutch by the compressive force.

In addition, in the case of the present invention, it is possible to easily recycle the brace.

Although the technical idea of the connection structure of the support beam of the present invention has been described above with the accompanying drawings, this is illustrative of the best embodiments of the present invention and is not intended to limit the present invention.
