[0005]

According to a first aspect of the present invention, there is provided a beam joining structure having an inverted L shape including a beam having an upper flange, a horizontal piece and a hanging piece, wherein the horizontal piece is joined to the upper flange of the beam. It has a mounting bracket, a beam cover that covers the front surface of the beam with the front surface of the hanging piece as a contact surface, and a connecting beam whose base is joined to the hanging piece via the beam cover.

According to the first aspect of the present invention, the structure of the beam is simplified by using a mounting member for attaching the connecting beam as a separate member from the beam. Also, since the mounting bracket is joined to the upper flange of the beam, it can be used for beams having different vertical dimensions. Further, since the mounting bracket comes into contact with the beam cover, the beam cover is not dented. According to a second aspect of the present invention, in the first aspect, the connecting beam has an end plate hanging downward at the base, and a lower portion of the end plate and a hanging piece of the mounting bracket are joined via a beam cover. It is characterized by the following.

According to the beam joining structure of the second aspect, in addition to the function of the first aspect, the lower part of the end plate is joined to the hanging piece of the mounting bracket, so that the joining operation can be easily performed from below the connecting beam. Can be.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a cross-sectional view of an outdoor corridor of an apartment house, 10 is a building body,
11 is an outdoor corridor. 12 is an outer wall panel on the first floor of the building main body 10, 13 is an I-shaped steel beam provided along the outdoor surface of the building, 14 is an outer wall panel on the second floor supported by the support hardware 15 on the beam 13, 16 Is a ceiling on the first floor, and 17 is a floor on the second floor. Reference numeral 18 denotes an outdoor floor of the outdoor corridor 11, reference numeral 19 denotes a connecting beam for supporting the outdoor floor 18, reference numeral 28 denotes a corridor beam provided along the outer edge of the outdoor corridor 11 and connects the tip of the connecting beam 19, reference numeral 20 denotes a handrail, Reference numeral 21 denotes a corridor curtain panel.

Next, referring to FIG. 2 and FIG.
9 will be described. Reference numeral 22 denotes a column to which both ends of the beam 13 are fixed. First, the mounting bracket 23 is joined to the beam 13. The mounting bracket 23 includes a horizontal piece 23a and a hanging piece 23b.
And is formed in an inverted L-shape. And mounting bracket 2
3 is placed on the upper surface of the upper flange 13a of the beam 13 via the support hardware 15, and bolts are inserted into bolt insertion holes (not shown) provided in the horizontal piece 23a, the support hardware 15, and the upper flange 13a. 26 and the upper flange 13a
Fasten to the nut welded to the lower surface.

Furthermore, the hanging piece 2 of the mounting bracket 23
The beam cover 24 covering the front surface of the beam 13 is brought into contact with the front surface of the beam 3b, and the end plate 25 welded to the base of the connecting beam 19 is fixed to the hanging piece 23b via the beam cover 24. That is, bolt insertion holes 25a, 24a, and 23c are provided in the end plate 25, the beam cover 24, and the hanging piece 23b.
Nuts 29 (FIG. 1) are welded to the back surface of the hanging piece 23b in advance, and these bolt insertion holes 25a,
The bolt 27 is inserted through the nuts 24a and 23c and fastened to the nut 29.

According to the beam joining structure having the above-described structure, the structure of the beam 13 is simplified by using the mounting bracket 23 for mounting the connecting beam 19 as a separate member from the beam 13.
Cost can be reduced. In addition, since the mounting bracket 23 is joined to the upper flange 13a of the beam 13, it can cope with various beams 13 having different vertical dimensions. Moreover, if the upper flange is provided, the mounting bracket 23 can be joined to a beam having a cross-sectional shape other than the I-shape.

Further, since the mounting bracket 23 comes into contact with the beam cover 24, the beam cover 24 is not dented. further,
The lower part of the end plate 25 is attached to the hanging piece 23b
Therefore, the joining operation can be easily performed from below the connecting beam 19. The horizontal piece 2 of the mounting bracket 23
3 a may be attached to the lower surface of the upper flange 13 a of the beam 13. Further, in the above embodiment, the outdoor corridor 11 of the apartment house is used.
However, the same structure can be applied to a connecting beam for supporting a balcony floor in a general house.

[0013]

According to the first aspect of the present invention, the structure of the beam is simplified by using a mounting member for mounting the connecting beam as a separate member from the beam. Also, since the mounting bracket is joined to the upper flange of the beam, it can be used for beams having different vertical dimensions. Furthermore, since the mounting bracket will hit the beam cover,
The beam cover does not dent.

According to the beam joining structure of the second aspect, in addition to the effect of the first aspect, since the lower portion of the end plate is joined to the hanging piece of the mounting bracket, the joining operation can be easily performed from below the connecting beam. Can be.
