BACKGROUND ART Traditionally, some buildings have had steel frames. This steel framework is equipped with an end plate at the end of the beam, which enables the beam to be bolted to the column, making it easy to connect the beam to the column at the construction site. Is there something that can be done?

3 to 5 show an example of a steel framework using end plates 30.

In the figure, an end plate 30 is welded to each end of each of the rods 2 to be joined to the pillar 1. Each end plate 30 is provided with a plurality of bolt insertion holes 31.

On the other hand, the column 1 consists of upper and lower column members IA and IB that are connected via connecting blocks 11 and 12. The joining block 11.12 is provided with a plurality of bolt holes 13 in each side wall corresponding to the positions of the bolt insertion holes 31 of the machined plate 30, and a tap plate 14 is disposed inside the joint block 11, 12. A plurality of tapped holes 15 are provided in the tap plate 14 at positions corresponding to the bolt holes 13 of the joining block 11.12.

The bolts 16 inserted through both the bolt insertion holes 31 of the end plate 30 and the bolt holes 13 of the joining blocks 11 and 12 are screwed into the threaded holes 15 of the tap plate 14, whereby the upper and lower joining blocks 11 ．． 12 are joined to each other, and the beams 2 are joined to the columns 1 to construct a steel framework.

In addition, when the vertical dimension of the tap plate 14 is shorter than the end plate 30, the bolts 16 at the uppermost and lowermost positions are screwed into nuts provided inside the joining block 11.12.

Some of these steel frame frames 2 have gusset plates 32 attached to both sides near the end on the column l side, and the cassette plate 32 has diagonal lines attached to the cassette plate 32 in order to strengthen the rigidity of the steel frame frame. The hook is connected to one end of the passed place 17.

[Problem to be solved by the invention]

In such a steel frame frame, the end plate 30 is
When welding to the end plate, the welding work must be carried out while maintaining the predetermined positional relationship between the thread 2 and the end plate 30, which poses a problem of making the welding work complicated.

In addition, when performing this welding work, the wire 2 and the end plate 3 are
There is also a problem that the positional accuracy between the rice cake 2 and the end plate 30 tends to be inaccurate because the positional relationship with the end plate 30 may deviate.

An object of the present invention is to provide a method for joining a kat and an end plate in a steel framework, which makes it possible to easily weld the end plate and the kat, and to make the positional relationship between the kat and the end plate accurate. It's about doing.

[Means to solve the problem]

The present invention provides a steel framework in which a cassette is joined to a column through an end plate and a brace is connected through a gusset plate, and after the gusset plate is joined to the end plate, the cassette plate is This is a work method for joining a casing and an end plate in a steel frame frame, which is characterized by placing a casing on top and welding the end plate and the casing.

[Function] According to the present invention, when welding the rice cake and the end plate, since the beam is supported by the cassette plate welded to the end plate, the positional relationship between the rice cake and the end plate can be accurately determined. This welding work can be performed while holding the

In addition, since the cassette plate is smaller and lighter than the beam, the cassette plate can be welded with high accuracy in height position relative to the end plate, and the cassette plate is placed on top of the cassette plate and the cassette is welded to the end plate. By doing so, it is possible to improve the positional accuracy of the rice cake and the end plate.

Embodiment 1: Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, the same symbols will be used for the same members as those already described, and the description thereof will be simplified or omitted.

In this embodiment, the end plates 30 and gasse bottom plates 32 in the steel framework shown in FIGS. 3 and 4 are replaced with the end plates 20 and cassette plates 22 shown in FIGS. 1 and 2.

In FIGS. 1 and 2, the end plate 20 is formed into a thick plate shape, and has a plurality of bolt insertion holes 2 on its surface.
A thin plate-like cassette plate 22 is horizontally welded to one surface of the cassette plate 22.The cassette plate 22 gradually becomes wider from the proximal end where it is welded to the end plate 20 toward the distal end. The widthwise dimension of the distal end is wider than that of the end plate 20. Both sides of the widened distal end protrude from both sides of the reel 2, and a place I7 is connected to each of the protruding parts. A connecting hole 23 is provided.

The casing 2 is made of steel and has an H-shaped cross section, and is placed on the gusset plate 22 and welded to both the end plate 20 and the gusset plate 22.

The beam 2 to which the end plate 20 and the gusset plate 22 are welded in this way is joined to the column 1 with the bolt 16 via the end plate 20, similar to the conventional example shown in FIGS. 3 to 5.

In this embodiment, the work of joining the rice cake 2 and the end plate 20 is performed in the following procedure.

First, the gusset plate 22 is welded to a predetermined position of the end plate 20, and assembled into a state where the cassette plate 2 can be placed as shown in FIG.
2 is smaller and lighter than the cassette 2, making the welding work easier, and the cassette plate 22 can be welded with high accuracy in height position relative to the end plate 20.

Next, the rice cake 2 is placed on the cassette plate 22 and the rice cake 2 is welded to the end plate 20. Here, although the beam 2 is welded to the end plate 20, it is supported by the set plate 22, so that the positional relationship between the beam 2 and the end plate 20 is accurate.

According to such an embodiment, the following effects can be obtained.

That is, when welding the wire 2 and the end plate 20,
Although it was welded to the end plate 20, since the set plate 22 supports the rice cake 2, this welding work can be performed while accurately maintaining the positional relationship between the rice cake 2 and the end plate 20. Welding work between the end plate 20 and the end plate 20 can be facilitated.

In addition, since the gusset plate 22 is smaller and lighter than the casing 2, the gusset plate 22 can be welded with high accuracy in height relative to the end plate 20. By welding to the end plate 20, the positional accuracy between the beam 2 and the end plate 22 can be improved, and the positional relationship between the beam 2 and the end plate 20 can be made accurate.

Note that the cassette plate 22 is not only connected to the cassette 2 but also to the end plate 20 by welding, so the frame including the cassette 2 connected to the place 17 is as follows.
The joint strength of the cassette plate 22 is improved, the connection strength of the place 17 can be improved, and therefore the rigidity of the frame can be improved.

It should be noted that the present invention is not limited to the above-described embodiments, but includes the following modifications and the like.

That is, the gusset plate 22 is not limited to one that protrudes from both sides of the rice cake 2, but may be one that projects only from one side of the rice cake 2. In short, it is possible to connect one or more places 17, and to place the beam 2 on. If possible, the shape and size are not limited.

Moreover, the cross section 2 is not limited to an H-shaped cross section, but may be a U-shaped cross section, and the cross-sectional shape is not limited as long as it can be joined to the pillar l via the end plate 20.

Furthermore, the pillar l is made of a plurality of pillar materials IA and IB connected to a joining block 11. Not limited to those added via 12,
It may be simply made of a single square piece of timber or the like, as long as the scallop 2 can be bolted to the side surface via the end plate 20.

Note that the position of the cassette plate 22 is not limited to the lower surface side of the rice cake 2, but may be placed on the upper surface side of the beam 2. In this case, after welding the end plate 20 and the casing 2, the casing 2 may be turned upside down.
