Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a joining device at the intersection of lattice girders constituting floors and roofs of miscellaneous objects.

Problems to be Solved by the Invention The applicant has previously developed the use of lamellar lattice girders as floors or roofs of prefabricated buildings. By the way, in the lamellar structure, connecting members on both sides of a continuous member are positioned orthogonally or intersectingly. Although it is easy to pin-join a connecting member to a continuous member, this may result in insufficient rigidity of the lamellar structure. Therefore, there is a need for a rigid or nearly rigid bolt joint that can be easily assembled on site. This invention was developed to meet the above-mentioned needs.

Means for Solving the Problems This invention involves sandwiching the continuous members by end plates provided at the joints of the members to be connected, interposing spacers between the end plates, and tightening them with bolts and nuts inserted through the end plates. or a structure in which consecutive members are sandwiched by an end plate provided across the joints of the connecting members, and the end plate is tightened to at least one of the connecting members with bolts or nuts. This is a tensile bolt connection that provides a rigid connection.

Embodiment Fig. 1 shows a lamellar structure formed using a section steel according to the present invention. Each member is of equal length, but the member passing through the joint is a continuous member A, and the intermittent member is a member A. Let it be the member B to be connected.

In Fig. 2, the members are made of channel steel, and end plates 1 are fixed to each end of member B to be connected. Cylindrical spacers 2 are provided to protrude from the web of continuous member A as necessary. It sticks to the shape. When joining, the end plate 1
, 1 sandwich the continuous member A, and each end plate 1. A bolt 3 is inserted into the cylindrical spacer 2 and tightened with a nut 4.

In FIG. 3, the member is made of H-beam steel, and spacers 2 are provided on both sides of the continuous web of member A.

In FIG. 4, a plate-shaped plate 2' is used in place of the cylindrical spacer 2.

Figures 5 to 11 show other modified examples.
In FIG. 6, the spacer 2 also serves as an end plate. Moreover, the spacer 2 can also be provided above and below the flanges of the member B to be connected.

FIGS. 7 to 11 show still other modified examples, in which the spacer 2 can be provided projecting above and below the member B connecting the end plate 1, and a case where the spacer 2 is shaped like a plate is also shown. There is.

Figures 12 to 14 show other variations using end plates and bolts and nuts.

In Fig. 12-I, l, a plate-shaped end plate 1 is attached to the upper and lower flanges of a continuous member made of lip channel steel, and is placed astride the joint of the connecting members B, B, and this end One end of the end plate 1 is fixed to one of the connecting members by welding, and the other end of the end plate 1 is overlapped with the 7 langes of the other connecting member B and bolts 3. Tighten with nut 4.

13 shows the case where members A and B are made of channel steel, and FIG. 14 shows the case where both ends of the end plate 1 are tightened with bolts 3 and nuts 4.

Effects of the Invention The present invention has the above-mentioned configuration, and allows the continuous members made of intersecting section steel etc. and the connecting members to be butt-like and tension-bolted joined, making it easy to assemble on-site. It can be rigidly connected, and the lattice girder with a lamellar structure can be integrally constructed.
