BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a girder of the present invention; FIG. 1 is a perspective view of a crossing jig in a horizontal cutting beam, and FIG. 2 is a front view of a crossing jig in a horizontal cutting beam.

The horizontal beam 1 comprises a beam 2 and a jig 3 for crossing. The horizontal beam 1 is formed by connecting several beam members 2 made of H-section steel, and an intersection jig 3 is bolted to the intersection of the orthogonal beams.

As shown in FIGS. 1 and 2, the crossing jig 3 has wide members 4 facing each other at appropriate intervals connected by upper and lower connecting members 5 and 6, and an orthogonal cut beam is inserted between them. A through hole 7 large enough to pass through is formed.

The lower connecting member 6 is formed integrally with the wide member 4 or is welded to the wide member 4, while the upper connecting member 5 is fixed with bolts 8 so that it can be freely removed. . Therefore, when the upper connecting member 5 is removed, the orthogonal cut beam 9 can be inserted into the through hole 7 as shown in FIG.

The height of the orthogonal beam 9 is the same as that of the horizontal beam 1.
However, when the height of the orthogonal beam 9 is lower or higher than that of the horizontal beam 1, the height and size of the upper connecting member 5 are changed.

Hereinafter, an embodiment of a method for erection of a girder using the above-mentioned horizontal girder will be described with reference to FIGS. Further, only the configuration different from that of the above-described embodiment will be described with different reference numerals. First, as shown in FIG. 3A, the horizontal beam 1 is installed and fixed to the bracket 11 of the column 10.

Next, as shown in FIG. 2B, the upper connecting member 5 of the intersection jig 3 is removed to open the through hole 7,
Here, orthogonal cut beams 9 having the same height as the horizontal cut beams 1 are inserted.

Next, as shown in FIG. 3 (3), the removed upper connecting member 5 is attached to the
Of the upper and lower connecting members 5 and 6
Welded to Then, the vibration-preventing angle 12 is sandwiched between the flanges 14 of the orthogonally cut beam with a vice 13 or the like, and the orthogonally cut beam 9 is fixed to the horizontal cut beam 1, and the horizontal cut beam 1 is preloaded by the jack 15.

After preloading the horizontal beam 1 in this way, as shown in (4) of the figure, the swing angle 12 is removed from the upper and lower connecting members 5 and 6, and the swing angle 12 is moved up and down. It is sandwiched between the connecting members 5 and 6 with a vise 13 or the like. Then, the horizontal cut beam 1 is fixed to the orthogonal cut beam 9, and the orthogonal cut beam 9 is preloaded by a jack (not shown). When this preloading is completed, as shown in FIG. 4, the horizontal beam 1 and the orthogonal beam 9 are combined with a vice 13 so as to be integrated, or they are fastened to each other with an auxiliary plate 13a and bolts 13b. .

In this way, the horizontal beam 1 and the orthogonal beam 9 are used.
As shown in FIG. 5, the cut beams 16 at the same level are installed between the retaining walls 17.
At the same time, the belly 18 is also attached at the same level, so that the fired material 19 is also erected horizontally, and
Is simplified.

When the height of the orthogonal beam 9 is lower or higher than that of the horizontal beam 1, the height of the upper connecting member 5 is adjusted and the bridge is installed in the same manner as described above. Also, if a thermometer or the like is set on the upper connecting member 5, only the member can be used as a measuring unit material, and the trouble of directly mounting at the current position can be omitted, and the precision can be improved because the mounting can be performed at the factory. Measurement management is also simplified.

[0022]

According to the present invention, the beams in different directions can be installed at the same level by inserting the orthogonal cut beams into the through holes of the intersection jig.

By removing the upper connecting member, the orthogonal cut beam can be easily inserted into the through hole of the intersection jig.

The beam can be easily installed.

Since the beams in different directions can be erected at the same level, the bulging is also at the same level, and the configuration of the entering corner is simplified.

It is possible to reduce the height of the retaining ridges and to omit the work of erection of the cutting beams.

Since the beams in different directions can be installed at the same level, the working space can be greatly expanded.

Since the space between the entrance gantry and the cutting beam is increased, the slope of the entrance slope can be made gentle.

Since the space between the cutting beam and the floor to be built is increased, workability is improved.
