For a large beam 51 made of H-shaped steel of a steel building, a plate 52 is provided between the upper and lower flanges 51a of the large beam 51, which is orthogonal to the web 51b and which is an upper and lower flange 51.
The upper and lower flanges 51 are oriented in the direction orthogonal to a and 51a.
a, 51a and the web 51b are joined by welding W, and the web 53b of the beam 53 is attached to the projecting plate portion 52b of the plate 52.
The small beam 53 may be connected to the large beam 51 via the plate 52 by joining the bolts 54 ...

た。In such a case, for example, conventionally, as shown in FIG. 3C, the upper and lower flanges 51 of the girder 51 are formed.
Welding W has been performed over the entire length of the three sides of the plate 52 facing the a, 51a and the web 51b.
【０００４】[0004]
【発明が解決しようとする課題】しかしながら、上記の
ように、プレート５２の三辺の略全長を溶接Ｗするので
は溶接長が非常に長くなってしまい、コストアップを招
くという問題がある。However, as described above, if the welding W is performed over substantially the entire length of the three sides of the plate 52, the welding length becomes very long, which causes a problem of cost increase.
【０００５】そこで、必要性のないあるいは少ない部分

るおそれがないではない。Therefore, it is conceivable to eliminate welding of unnecessary or small portions and give instructions to the welding operator by welding or the like so that welding can be performed for a minimum required length. The instructions alone do not prevent accidental welding of the parts that do not need to be welded or accidental welding of the parts that must be welded.

性を越えて大きなものになってしまうという問題もあっ
た。When the plate 52 is used for mounting the beam girder 53, the plate 52 is designed to be thick as a whole in order to secure the proof stress of the joint between the beam girder 51 and the beam girder 53. Therefore, there is also a problem that the total weight of the plate 52 exceeds the necessity and becomes large.

トの取付け構造によって解決される。SUMMARY OF THE INVENTION The above problem is that the plate is oriented between the upper and lower flanges of a steel beam having a web between the upper and lower flanges in a direction orthogonal to the web and orthogonal to the upper and lower flanges. In the structure for mounting a plate on a steel beam, the plate is welded to both sides facing the flange, and the side facing the web is provided with a notch in the middle thereof. This is solved by a structure for attaching a plate to a steel beam, characterized in that both portions sandwiching the notch are welded to the web.

ある部分のみを確実に溶接させることができる。In this mounting structure, since the plate is provided with a notch in the middle of the side facing the web, the notch is separated from the web when the plate is assembled to the steel material, The welding operator avoids the notch and performs welding. Therefore, the presence of this notch allows the welding length of the plate to be shortened and the cost to be reduced, and the welding operator can confirm the presence of the notch even if no special instructions are given. The portion to be welded and the portion not to be welded can be surely discriminated from each other, and the welding operator can surely weld only the portion to be welded.

ることができる。The plate is a plate for connecting the beam, and when the plate is locally reinforced by locally stacking a reinforcing plate on the region connecting the beam and integrally mounting it, the plate is a plate. The overall weight of can be reduced. That is, when the plate is composed of one piece, it is necessary to make the whole plate thicker in order to make the part connecting the beam beams of the plate thicker, but only the part connecting the beam beams is used by using the reinforcing plate. By locally thickening the reinforcing plate, other portions can be thinned, and the weight of the entire plate including the reinforcing plate can be reduced.

くつくということはない。The plate 2 of the plate 2 has a large beam 1
Between the upper and lower flanges 1a, 1a of the web 1 in a direction orthogonal to the web 1b and orthogonal to the upper and lower flanges.
It can be properly arranged in the inside surrounded by b and the upper and lower flanges 1a, 1a, and a notch 5 is provided in the middle of the side facing the web 1b. In the notch 5, the plate 2 has the web 1b.
It is designed to be separated from the surface. Since the plate 2 is processed with an eye tracer, etc.
However, even if the notch 5 is provided, the processing cost does not become particularly high.

It is arranged inside the web 1b of the girder 1 and the upper and lower flanges 1a and 1a. As shown in FIG. 1C, the upper and lower sides of the base plate portion 2a are welded to the upper and lower flanges 1a and 1a by welding. As for the side facing the web 1b, the upper and lower sides sandwiching the cutout portion 5 are welded W to the web 1b.

い。In this welding, the welding operator, due to the presence of the cutout portion 5 of the plate 2, is in a state of abutting with the web 1b at a portion facing the web 1b at both upper and lower sides sandwiching the cutout portion 5. This is naturally recognized, and only the upper and lower sides are welded W. The depth dimension of the notch portion 5 may be one for making the welding operator recognize that the notch portion 5 exists therein, but the welding cannot be performed even when trying to weld the web 1b. It is particularly preferable that the depth dimension is set as described above.

ことができる。As described above, in the plate mounting structure described above, since the plate 2 is provided with the notch 5 in the middle of the side facing the web 1b, the plate 2 is not attached to the girder 1 by not welding that part. The welding length of 2 can be shortened to reduce the cost, and moreover,
Due to the presence of the notch portion 5, it is possible for the welding operator to definitely distinguish the portion to be welded and the portion not to be welded, and it is possible to reliably weld only the portion that needs to be welded.

その軽量化を図ることができる。In the second embodiment shown in FIGS. 2A, 2B and 2C, the thickness dimension of the plate 2 is set smaller than that of the first embodiment, and the projecting plate of the plate 2 is set. The reinforcing plate 7 is locally overlapped in a range extending from the portion 2b to the base plate portion 2a on the base end side, and the reinforcing plate 7 is integrated with the plate 2 by welding W to locally reinforce the plate 2. As a result, the plate 2 and the reinforcing plate 7 can be compared with the case where the plate 2 having a thick wall size is used for connecting the beam 3 as in the first embodiment.
The weight of the whole plate including and can be reduced,
The weight can be reduced.

ことはいうまでもない。Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above-described embodiment, the structure for attaching the plate 2 to the girder 1 when the beam 3 is connected to the girder 1 via the plate 2 is shown. However, a plate is simply attached to the beam for reinforcement thereof. It may be used for a mounting structure when mounting by welding. Further, the steel frame beam is not limited to the H-shaped steel beam, and may be an assembled steel beam, a channel steel beam, or the like, as long as a web is provided between the upper and lower flanges. It goes without saying that it is good.
