Description

[Detailed description of the invention] Industrial field of application This invention relates to the structure of a three-dimensional truss that constitutes the roof of a building.

Problems to be Solved by the Invention In the past, various structures have been proposed in which the assembly members are made into units when assembling the structure of a space truss. For example, as shown in Japanese Unexamined Patent Publication No. 57-112537 (Japanese Patent Publication No. 58-54225), the applicant previously proposed that a single gusset plate was used to join the bundle material, chord material, and belly material around the joint part. We have developed a structure that can be kept compact. By the way, in the patent application filed on the same date (Japanese Patent Publication No. 1-32340), the applicant combined three equal-length members in an H shape to form a unitary member, and a large number of these unitary members were connected in series. We developed a framework for constructing a three-dimensional truss for a structure with a wickerwork shape. As a joint part of this structure, the means shown in the above-mentioned publication is applied, and the joint structure of the publication is such that two joining plates are attached to the tip of the belly material with a gap between them. In contrast, in this design, the gazette plate can be attached to the mounting plate from the outside, increasing the size of the unit member, and creating a three-dimensional truss that forms a rectangular, diamond-shaped, etc. lattice. This structure has been improved to a structure that can be joined rationally and efficiently.

Structure and Examples of the Idea The gist of this idea is to create an H
The unit members are combined in a shape to form one unit member, and this unit member is joined at each end and the center, and the connection at the center is made by mounting plates provided at the upper and lower ends of the bundles provided on the upper and lower chord members. This is a structure of a three-dimensional truss characterized by the fact that the end of the unit member and the end of another unit member are connected via a gazette plate.

The details will be explained below based on the illustrated embodiment.

The truss-shaped unit frame member 1 has an upper chord member 2a and a lower chord member 2.
b are connected by a frame member 3, and this unit frame member 1 is combined to form an H shape to form one unit member A.
and are joined at each end and center to form a three-dimensional structure, that is, a three-dimensional truss framework.

A bundle material 4 is provided in the center of this unit frame material 1, and upper and lower chord members 2 are provided at the upper and lower ends of the bundle material 4 via plates 5.
The bundle material 4 is fixed to a and 2b. Also, upper and lower chord materials 2
Mounting plates 6 are provided in a direction perpendicular to the upper and lower chord members 2a, 2b of the other unit frame members 1 through two gusset plates 7. It is joined.

Furthermore, a gusset plate 8 is provided spanning the adjacent upper and lower chord members 2a and 2b. Further, a filler plate is interposed between two gusset plates 7, and the end belly member 3 is attached to the gusset plate 7.

Effects of the invention This invention consists of the above configuration, and the unit members are H
It has a truss-like structure, and the unit members are joined at each end and center to form a three-dimensional structure, which allows the unit to be larger during erection, reducing the number of lifting members. This reduces assembly work at heights, improving safety and reducing work time. Further, at the joining portion of the unit members, mounting plates are provided at the upper and lower ends of the bundle material, gusset plates are applied from the sides to the mounting plates, and the bolts are tightened, thereby making it possible to join orthogonal unit members in a well-controlled and compact manner.
