However, the channel of the basic unit of the building has a U-shaped channel in order to prevent corrosion of the foundation joint due to rain and to improve the appearance of the building. The vertical flat back surface is directed outward, and the surface to be connected to the foundation bolt is fixed to the foundation. For this reason, since the connecting position of the channel and the foundation bolt at the lower part of the building is not visible from the outside, the positioning must be performed under the floor. Therefore, work was difficult and dangerous.

Conventionally, when a lower channel of a building is connected to a foundation bolt, a method is used in which a round hole formed in the channel is passed through the foundation bolt and nuts are tightened. Not only requires strict precision in the position of the bolt holes, but also requires a great deal of labor for alignment, and furthermore, since such complicated work is performed under the floor, the work efficiency has been significantly reduced. .

Accordingly, a first object of the present invention is to facilitate alignment of a foundation bolt with a bolt hole of a lower channel of a building, and to perform connection / disassembly work of the foundation bolt and the channel from outside the building. It is to provide a building channel member.

In order to solve the above problem, the present inventor has formed an L-shaped notch along an angle of a channel and connected the base to a base bolt through a connection fitting having a long bolt hole. However, if a notch is formed at the angle of the channel, there is a problem that the channel may be bent from the notch depending on how to handle the channel.

Accordingly, a second object of the present invention is to provide a method of handling a channel that does not damage the channel during transportation or the like even if an L-shaped notch is formed in the angle of the channel.

[0008]

In order to achieve the first object, a channel member for a building according to the present invention is connected to a lower part of a building and is fixed to a building foundation via a foundation bolt. A connection fitting for connecting the channel body to a foundation bolt, wherein the channel body has a notch having an L-shaped cross section along a bottom plate and a side plate of the channel body at a connection portion to the foundation bolt. And a pair of bolt holes facing the left and right side plates sandwiching the cutout portion of the channel body, and the connecting fitting has an elongated hole through which the base bolt is passed in the longitudinal direction. In addition, a bolt hole corresponding to the bolt hole of the side plate of the channel body is provided at both ends in the longitudinal direction.

In order to achieve the second object, the method for handling a channel member according to the present invention is characterized in that a connecting fitting is detachably connected to a bolt hole of the channel body via the bolt hole when the channel member is carried. Thus, the L-shaped notch of the channel body is reinforced with the connecting metal.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings. The channel member for a building according to the present invention includes a metal channel main body 2 made of steel or the like fixed to a foundation 1 of a building, and a connection fitting 4 for connecting the channel main body 2 to a mounting bolt 3 of the foundation 1. Have been.

As shown in FIG. 1, the channel main body 2 of the embodiment shown in FIG. 1 has a basic basic unit (division unit) of the building on the upper plate 2a with the opening side of the U-shaped steel material facing the inside of the building. 5 is assembled to connect the bottom plate 2b to the bolt 3 of the foundation 1. Accordingly, the channel body 2 is fixed to the foundation 1 such that the flat vertical side surface 2c appears outside the building.

As shown in FIGS. 1 and 2, the channel main body 2 is provided with an L-shaped notch 2d having a predetermined width along an angle between the bottom plate 2b and the side plate 2c at a position where the channel body 2 is attached to the foundation bolt 3. It is formed. The notch 2d can be formed by cutting the L-shaped angle portion of the channel main body 2 by a predetermined width as shown in FIG. 3, but may be formed by other known means.

As shown in FIG. 2, the channel body 2 is
Further, a pair of bolt holes 6, 6 for temporarily fixing the connection fitting 4 are formed near both side edges of the notch 2d. The bolt holes 6, 6 may be located at any positions as long as they are near both side edges of the notch 2d. However, in order not to hinder the work of attaching the channel body 2 to the foundation 1, the notch of the side plate 2c is required. It is desirable to form it on the portion 2d (1).

The connection fitting 4 is made of a steel plate longer than the notch width W of the notch 2d, and the base 1 extends in the longitudinal direction.
Slot 7 for passing the foundation bolt 3 of
Bolt holes 8, 8 corresponding to the bolt holes 6, 6 of the channel main body 2 are formed outside both ends of the long hole 7.

When the channel main body 2 of the present invention connected to the lower part of the building is fixed to the foundation 1, the following procedure is taken. That is, in the present invention, since the L-shaped notch 2d is formed in the bottom plate 2b and the side plate 2c of the channel body 2 connected to the lower part of the building, the building basic unit 5 lifted by a crane or the like is used as the base 1 When lowering to the fixing position, the bolt of the base 1 and the L-shaped notch 2d of the channel body 2 are viewed from the outside through the side plate notch 2d (1) of the L-shaped notch 2d to see the fixing position of the base 1. Perform position adjustment. Next, the base bolt 3 is passed through the long hole 7 of the connection fitting 4, and both ends of the connection fitting are cut at the bottom plate cutout 2 d of the cutout 2 d.
The connection member 4 is arranged so as to be engaged with both side edge plates in (2) and the connection member 4 is tightened with a nut. Thus, the channel body 2 of the building basic unit 5 is fixed to the foundation 1.

When the channel body 2 is removed from the foundation 1 for dismantling the building, a tool can be inserted through the opening of the channel side plate 2c of the cutout 2d and dismantled in the reverse operation step. In this case, the opening width and opening height of the notch 2d (2) formed in the side plate 2c of the channel main body 2 are set to dimensions that allow the above-described joining and dismantling work from outside the building.

If the L-shaped notch 2d is formed in the long and thin channel body, the channel body may bend at the notch 2d during transportation. Therefore, until the channel main body 2 is set at the predetermined mounting position of the foundation 1, the bolt holes 6, 6 formed at both end edges of the notch 2d of the channel main body 2 are provided with the bolt holes 8, both ends of the connecting fitting 4, 8 are connected by bolts and nuts, and the notch 2d of the channel body 2 is reinforced by the connection fitting 4.

In addition, by attaching the connection fitting 4 to the notch 2d, not only reinforcement but also a channel member composed of the channel main body and the connection fitting 4 is integrally conveyed.
