[0001]

[Industrial applications]

 The present invention relates to a lattice beam.

[0002]

[Prior art]

 Conventionally, a thing as shown in FIG. 5 is provided as the last beam A. In this lattice beam A, a lattice member 4, a connecting plate 6 and an end plate 3 are installed between an upper chord member 1 and a lower chord member 2 which are arranged so as to face each other. Are connected and fixed to each other. When the connecting plate 5 is provided with connecting holes 5 at predetermined intervals along the longitudinal direction, and another lattice beam B is installed so as to bridge between the adjacent lattice beams A as shown in FIG. In this case, the end plate of another lattice beam B is joined by bolts and nuts using the connecting hole 5 of the connecting plate 6, whereby another lattice beam B can be installed between the adjacent lattice beams A. It is like this. In this case, the outer wall may be set back depending on the construction site. In this case, another lattice beam B is installed at the connecting positions at predetermined intervals as shown by the solid line in the figure. Since it is displaced from the position of the connecting plate 6 that is present, it becomes impossible to join the lattice beams A and B to each other using the connecting plate 6 that is installed in advance. For this reason, in the conventional case, after the accurate positioning is performed at the construction site, the connecting plate C is separately disposed between the upper chord member 1 and the lower chord member 2, and the end portion of the connecting plate C is welded. The upper chord member 1 and the lower chord member 2 are fixed by welding so as to correspond to each other.

[0003]

[Problems to be solved by the device]

 However, in the conventional example as described above, the welding work must be performed after the positioning of the connection plate C is accurately performed at the construction site during the connection work of the lattice beam. There was a problem that it took time to position the wire and route the welding cable, which made connection work troublesome. In addition, when welding, it is necessary to be careful of fires, which is a troublesome work.

The present invention is intended to solve the above-mentioned problems, and it is an object of the present invention to provide a lattice beam capable of easily attaching a connecting plate and adapting to various outer wall setback dimensions. To do.

[0005]

[Means for Solving the Problems]

 In the present invention, in order to achieve the above object, an end plate 3 is installed between the opposite ends of an upper chord member 1 and a lower chord member 2 which are arranged so as to face each other. Are connected to each other by a lattice member 4 and have connecting holes 5 at predetermined intervals along the longitudinal direction of the upper chord member 1 and the lower chord member 2 so as to extend between the upper chord member 1 and the lower chord member 2. 6 is installed, a connecting piece 7 is projected from the inner surface of the end plate 3 substantially parallel to the connecting plate 6, and a supporting piece 8 is projected from the inner surface of the end plate 3 so as to be orthogonal to the connecting plate 6. A connection plate 10 having a plurality of connection holes 9 at predetermined intervals along the longitudinal direction is arranged along the lower portion of the upper chord member 1, and is a plurality of beams A at predetermined intervals along the longitudinal direction.

Is provided. Connecting pieces 6b project from the upper and lower ends of the main body 6a having the connecting holes 5, and the upper and lower connecting pieces 6b are fixed to the inner surfaces of the wall pieces 1a and 2a of the upper chord member 1 and the lower chord member 2. A connecting plate 6 is attached between the upper chord member 1 and the lower chord member 2. Here, the connecting piece 6b is protruded from the end of the main body 6a so as to be recessed from the main body 6a by one step, and the connecting piece 6b is fixed to the inner surface of the upper chord member 1 or the lower chord member 2 to oppose the upper chord member 1 The outer surface of the main body 6a is flush with the outer surfaces of the wall pieces 1a, 2a of the upper chord member 1 and the lower chord member 2 in the state of being arranged between the lower chord member 2 and the lower chord member 2. Here, as an arrangement state of the connection plate 6, for example, when the length dimension of the lattice member 4 is 3600 mm, it is laid between the upper chord member 1 and the lower chord member 2 at a 900 mm pitch.

As shown in FIG. 1 and FIG. 5, the lattice member 4 is mounted between the end plate 3 and the connecting plate 6 or between the adjacent connecting plates 6 by attaching the end plate 3 or the connecting plate 6 to each other. It is installed diagonally between the upper chord member 1 and the lower chord member 2 so as not to overlap at a position. The connecting plate 10 mounted along the lower portion of the upper chord member 1 between the end plate 3 and the connecting plate 6 is provided with connecting holes 9 at predetermined intervals over the entire length as shown in FIGS. The main body is constructed by projecting a connecting piece 10b connected to the connecting plate 6 from one end of the main body 10a and projecting a connecting piece 10c connected to the connecting piece 7 from the other end of the main body 10a.

Another lattice beam is installed between A. 12 is a pillar.

When the outer wall is set back, the connection position of another lattice beam B to the lattice beam A is displaced from the position of the connection plate 6. In this case, the connection plate 10 is bolted. It is attached to the lattice beam A by joining, and another lattice beam B is attached via the connection plate 10. That is, when the attachment position of another lattice beam B is located on the front side of the position of the connection plate 6 in FIG. 4, the connection between the end plate 3 and the connection plate 6 is performed as shown in FIG. The plate 10 is attached by bolt connection, and another lattice beam B is bolted to the lattice beam A through the connection hole 9 of the connection plate 10 as shown by the solid line in the figure. Reference numeral D in FIG. 1 denotes a joint portion formed by bolts and nuts. Further, when the attachment position of another lattice beam B is located behind the position of the connecting plate 6, as shown in FIG. Then, another lattice beam B is bolted to the lattice beam A through the connection hole 9 of the connection plate 10 'as shown by the chain double-dashed line in the figure.
