Description

[Detailed Description of the Invention] The present invention relates to a handrail attachment device, and particularly to a device for attaching a new handrail using the supports of an existing handrail.

When installing a new handrail using the supports of an existing handrail, it is known that the new support is fitted to the existing support and upper and lower chord members are connected to the new support.

However, with this mounting structure, it is necessary to manufacture and prepare a new support with a size and shape that matches the size and shape of the existing support, which is disadvantageous in terms of cost, and there is a gap between the existing support and the new support. This is likely to occur, so caulking is required, and furthermore, it is necessary to drill tapped holes in the existing pillars to secure the new pillars.

In summary, with a mounting device that fits and secures a new post into an existing post, the dimensions and shape of the new post are limited by the dimensions and shape of the existing post, and the work of installing a new handrail is extremely troublesome. There are other defects.

The present invention was developed in view of the above circumstances, and its purpose is to make it possible to install a new support using an existing support with a simple installation process, and to also enable the size and shape of the new support to match the dimensions and shape of the existing support. It is an object of the present invention to provide a handrail mounting device which is not limited by the following.

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 is an overall front view, in which the lower part of an existing column 1 is buried and fixed in the frame A, a new column 2 is attached to the existing column 1, and an upper chord member 3 and a lower chord member are attached to the new column 2. 4. The cap 5 is attached, and the stand 6 is attached between the upper and lower chord members 3 and 4, and the stand 6 is attached between the cap 5 and the lower chord 4 to form the new handrail B. .

The existing pillar 1 has front and rear walls 1a, 1 in the prospective direction.
b and the left and right walls 1c, 1d in the viewing direction form a rectangular cross-sectional shape, and a pair of left and right mounting bodies 10, 10 are attached to the left and right walls 1c, 1d in the vertical direction.

The mounting body 10 is a thin plate-like body, and one side 11 in the viewing direction is a flat surface, and the other side 12 has a concave portion 13 formed in the longitudinal direction, and both end surfaces 14, 14 in the viewing direction are formed. Narrow fitting grooves 15, 15 are formed in the longitudinal direction, and an inner wall portion 15a constituting the fitting groove 15.
are tongue-shaped and bent diagonally inward, and have sawtooth locking concave and convex portions 16 formed on their inner surfaces, and a pair of upper and lower horizontal holes 17 penetrating through both side surfaces 11 and 12, respectively. It has been formed.

In the left and right walls 1c and 1d of the existing support column 1, holes 18 are formed to match the horizontal holes 17, respectively.

The newly installed support columns 2 have a pair of support bodies 2 in the projected direction.
0, 20, the support body 20 is made by bending a plate-like long material to match the size and shape of the existing support column 2, and has a substantially U-shaped cross section with the intermediate wall 21 and the bent walls 22, 22 on both sides. The tip ends of both side bent walls 22, 22 have a plate thickness that fits into the fitting groove 15, and the inner surface 22a thereof has a sawtooth engagement uneven portion that engages with the locking uneven portion 16. 23 are formed respectively.

Then, install the mounting bracket 3 for the upper and lower chord members 3 and 4.
0 and 31 vertical pieces 30a and 31a are fitted into the recessed parts 13 and 13 of the pair of mounting bodies 10 and 10,
The bolts 40 are inserted through the horizontal holes 32, 33, the horizontal holes 17, and the holes 18, and the nuts 41 are tightened to attach the pair of left and right mounting bodies 10, 10 and the mounting bracket 30 to the left and right walls 1c, 1d of the existing column 1. , 31 are tightened and fixed.

Further, the pair of support bodies 20 have their both side bent walls 22, 22 fitted into the fitting grooves 15, 15 of the pair of left and right mounting bodies 10, 10, and the inner wall portion 15a.
is displaced outward, and the locking concavo-convex portion 16 and the engaging concavo-convex portion 23 are engaged and fixed to be attached to the existing support column 1. In other words, it is fitted and press-fitted into the fitting groove 15.

Note that the upper and lower chord members 3, 4 are provided with retaining plates 42,
They are connected to each other via screws 43, and the cap plate 5 is attached to the horizontal piece 34a of the mounting bracket 34, which is bolted in the same way as described above.
3 and is in contact with the upper surface of the upper cover 50.

The upper cover 50 includes a horizontal plate 51 that abuts between the upper end surfaces of the pair of support bodies 20, 20, a bent piece 52,
52, and the bent pieces 52, 52 are screwed to the bent wall 22 of the support body 20 to close the upper openings of the existing support 1 and the new support 2.

Therefore, the new support support 2 can be attached using the existing support support 1, and the new support support 2 is made up of a pair of support bodies 20, 20, and the support body 20 is a long plate-shaped body that is bent. Bending walls 22, 22
The fitting grooves 15, 1 of the pair of left and right mounting bodies 10, 10
5, the dimensions and shape of the new strut 2 are not limited to the dimensions and shape of the existing strut 1, and the long plate-like body can be folded to match the dimensions and shape of the existing strut 1. Since all you have to do is bend it, it is easier to manufacture and the cost is lower.

Further, the support body 20 is connected to the fitting groove 15 of the mounting body 10.
Since it is installed by fitting and crimping inside, it can be installed without troublesome work such as fixing with screws, making the installation work easy.

Furthermore, since a part of the support body 20 can be brought into contact with the existing support column 1, there is no need for caulking.

In addition, it is only necessary to form a hole 18 in the existing column 1 through which the bolt 40 that fixes the mounting body 10 is inserted, and there is no need to form a tapped hole or the like, so there is no need to perform troublesome tapped hole machining when installing a new column. ,
Installation work becomes easier.

Further, since the inner wall portion 16a of the mounting body 10 is displaced to press and engage the locking uneven portion 16 and the locking uneven portion 23, the mounting strength of the support body 20 is increased.

The present invention is as described above, and the new support support 2 can be installed using the existing support support 1 with simple installation work, and the dimensions and shape of the new support support 2 are not limited to the dimensions and shape of the existing support support 1. do not have.
