Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a horizontal frame mounting device that can mount horizontal frame members off-center to a mounting plate for mounting horizontal frame members pre-installed on a lattice beam such as a second floor beam.

For example, in a partially one-story two-story building with a prefabricated structure, horizontal members 3 such as the main building are attached at right angles to the second-story beam using lattice beams 2, as shown in Figure 4. At this time, for example, in order to form a flat roof with a gentle slope B different from the standard slope A, for example, the spacing between the mounting plates is different from the standard position a defined by the reference module shown by the dashed line in the figure. It is necessary to install a purlin in a solid line position with a wide width, and in this case, a new lattice beam must be manufactured each time, or mounting plates can be installed in various positions in advance, and a lattice beam with an extremely wide mounting plate must be prepared. This is extremely complicated and expensive in terms of design, production, and management.

The object of the present invention is to provide a horizontal member mounting device for mounting horizontal members off-center using upside-down mounting fittings, and one embodiment thereof will be described below with reference to the drawings.

In FIGS. 1 and 2, a horizontal member attachment device 1 of the present invention is for attaching a horizontal member 3 to a lattice beam 2 via attachment fittings 4, and the lattice beam 2 has an upper chord member 5 and a lower chord member 6. A mounting plate 8 having an outer surface flush with the side surface C and having bolt holes 7 arranged in parallel in multiple stages is installed at a predetermined position of the reference module between the upper and lower chord members 5 and 6 and facing each other on both sides thereof. be done.

The mounting bracket 4 has an upper piece 9 and a vertical piece 10 bent at right angles to each other.
The upper piece 9 is placed on the upper surface of the upper chord member 5, and in this embodiment, the other end of the upper piece 9 is bent downward, and the bent piece 11 allows The upper chord member 5 can be inserted into the upper chord member 5.

The vertical piece 10 has a mounting part 12 whose inner surface is in contact with the mounting plate 8 and is mounted thereon, and a lattice beam 2 which is divided into the thickness of the mounting part 12 and does not collide with the mounting plate 8 and the upper chord member 5.
Four parts 13 that fit inward are provided, and through holes 14 are formed through the mounting part 12 and the recessed part 13 at equal intervals to the mounting plates 1-8.

For example, a purlin can be formed by the horizontal member 3 using a hanging beam, and a mounting hole 16 whose hole center coincides with the through hole 14 is bored in the end play I.15.

However, in the horizontal member mounting device 1 of the present invention, the upper piece 9 of the mounting bracket 4 is placed on the upper chord member 5, and the mounting portion 12 of the vertical piece 10 is mounted on the mounting plate 8 using bolts 19 and nuts 1 to 20. The mounting bracket 4 is fixed to the ratchet beam 2 by screwing.

At this time, the recess [3] which is lower than the mounting part 12 by the thickness of the plate is flush with the outer surface of the mounting plate 8, and therefore the horizontal member 3
The end play river without shortening or changing its overall length.
15 can be screwed into the recess 13.

As shown in the diagram above, the device of the present invention can mount the horizontal members 3 off-center with respect to the mounting plates 8 that are spaced apart in units of reference modules, and is particularly suitable for installing the horizontal members 3 of main buildings etc. with different roof slopes. It can be used for installation, without the hassle of forming a large mounting plate in advance or changing the mounting position for each roof slope.
In addition to eliminating costs and facilitating inventory management, the upper piece 9 is placed on the upper chord member 5, so it can bear a large vertical force.

As shown in FIG. 3, when the upper chord member 5 is provided with an angle upper stand 22 for attaching the panel, the upper piece 9 is set to be less than half the middle dimension of the upper chord member.
