Description

[Detailed description of the invention] This invention relates to an improvement of a horizontal place mounting device.
More specifically, the beams 2 are constructed between the plurality of square pillars 1 so that the planar shape becomes a polygon of quadrilateral or larger, and the mounting surfaces are attached to the opposing inner corners 3 of the square pillars 1 located diagonally. 4
are fixed to each other, and a tensioning tool 6 is placed between the mounting bracket bodies 5 located on the diagonal line.
This relates to a horizontal place mounting device that includes a horizontal place mounting device.

In the conventional example, as shown in FIGS. 1 and 2, it was not possible to attach the horizontal place, which is the tensioning tool 6, directly to the prism 1, so the flange 7 on the lower side of the beam 2 was placed close to the prism 1. The end of the tensioning tool 6 was bolted to the portion.

Now, if the distance between the mounting position of the tensioning tool 6 and the prism 1 is e, and the angle between the tensioning tool 6 and the beam 2 is θ, then the tensioning tool 6 has a T
In addition to the tensile force, when a tension force of
A moment of inθ×e is applied.

Furthermore, since the tension T acts as a concentrated stress on the flange 7 of the beam 2, there is a drawback that local deformation of the flange 7 is likely to occur.

The present invention was made in view of the drawbacks of the conventional example,
The purpose of this invention is to connect mounting brackets whose mounting surfaces are fixed to opposite inner corners of diagonally located prisms and are bent in a substantially dogleg shape so that they can be pulled together using a tensioning tool. This allows direct horizontal force (
To provide a horizontal place mounting device which can apply tension T) to a square column, prevent excessive moment from being applied to the corner column, eliminate stress concentration on the flange of a beam, and prevent local deformation.

The present invention will be described in detail below according to illustrated embodiments.

The mounting bracket main body 5 is composed of a place connection part 8 and a column connection part 9, as shown in FIG.

The column connection part 9 is a rectangular plate bent into a dogleg shape, and has a bolt hole 10 bored at its tip, and a plate-shaped place connection part 8 protruding from its protruding corner 11. , a round hole 12 is bored at its tip.

The tensioning tool 6 has a connecting plate 14 welded to both ends of a bar 13, and the central part of the bar 13 is connected with a screw and nut so that the length of the tensioning tool 6 can be expanded and contracted. A round hole 15 for attachment is bored at the tip of 14.

Mounting plates 16 are welded to both ends of the beam 2, and a large number of bolt holes 10 are bored in the mounting plates 16.

In this embodiment, however, four square columns 1 are erected, and mounting plates 16 are bolted to the sides of the square columns 1, and beams 2 are constructed between the square columns 1 so that the planar shape is rectangular. That's how it is.

Next, the mounting bracket body 5 is installed from above the mounting plate portion 16 of the two mutually orthogonal beams 2, and the bolt 17 is inserted through the mounting plate 16.
Screw the mounting bracket body 5 onto the prism 1 using the steps.

Furthermore, the connecting plate 14 of the tensioning tool 6 is pivoted to the brace connecting part 8 of the pair of mounting bracket bodies 5 arranged diagonally with bolts and nuts, and then the screw at the center of the bar 13 is The length of the bar 13 is shortened at the part and the nut part, and the tensioning tool 6 is
Make sure to hold it.

In this case, the tension T is applied at an angle of 45° to the bolt 17, so the bolt 17 and the threads of the nut hole will not be crushed by the tension, and the bolt 17 will not loosen or fall off. It is.

As mentioned above, in the present invention, beams are erected between a plurality of erected prisms so that the planar shape becomes a polygon of quadrilateral or larger, and the inner corners of the diagonally located prisms face each other. Since the mounting bracket bodies, whose mounting surfaces can be concavely bent into a substantially dogleg shape, are fixed to each other, and the tensioning tool is attached between the mounting hardware located on the diagonal line, the horizontal force (tension T) applied to the tensioning tool is is now applied directly to the prism, and there is no need to apply an extra moment as in the conventional example, which has the advantage of allowing the prism to flow smoothly in the horizontal direction. Since it is not connected to the flange of the beam, horizontal force is not locally concentrated on the flange, causing local deformation.
