Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a rail attachment structure for attaching a horizontal rail such as a balcony handrail to a support.

[Prior art]

Conventionally, when installing the upper and lower horizontal bars of handrails, etc., as shown in Figure 3, attach the mounting angle b to the support post a, tighten and fix it with the bolt c, and then attach the support piece d that extends laterally from the mounting angle b. Generally used is a structure in which a handrail plate e, which is a horizontal beam, is placed on the rail and fixed by tightening with bolts f and nuts g.

[Problems to be solved by the idea]

The conventional method of mounting an angle using the general bolt and nut described above is not only unstable as it involves tightening only one bolt, but also requires the installation work to involve inserting and tightening the bolt into an insertion hole drilled in the support. It is time consuming, cumbersome, and expensive.

[Means for solving problems]

In order to eliminate the above-mentioned problems, the present invention provides a suitable fixing fitting in the lower slit of the column, which has slits arranged at intervals on the upper and lower sides, and connects the hook from the mounting angle located in the upper slit to the lower edge of the slit. At the same time, insert the lower part of the mounting angle between the support provided on the fixing bracket and the rising piece that stands up with a gap, and lock it by the hook part and the fixing bracket, and then attach it to the mounting angle. To provide a crosspiece mounting structure in which the crosspiece is attached by tightening the horizontal crosspiece with bolts and nuts on a laterally protruding support plate provided.

〔Example〕

Reference numeral 1 denotes a support column, and slits 2 and 3 are provided at intervals above and below the crosspiece attachment portion of the support support 1. The lower slit 2 is bent to fit the width of the support 1 to form a shape 4a, and both ends of this are further shaped into an L shape to fit the slit 2, and a lower part 5a of a mounting angle 5, which will be described later, is formed between the lower slit 2 and the support 1. A gap m large enough for insertion is provided, and the fixing metal fitting 4 bent upward is fitted. A locking pawl 4c is provided at the tip of each upwardly bent piece 4b of the fixture 4. The mounting angle 5 is a receiving plate 5b that extends laterally to the outside of the intermediate portion.
and a locking hook piece 5 on the inside that approximately matches the plate thickness of the support post 1.
When the mounting angle 5 is lowered along the support 1 with the locking hook piece 5c positioned inside the upper slit 3, the locking hook piece 5c positioned inside the slit 3
c is lowered along the slit 3 to lock the locking hook piece 5c to the lower edge 3a of the slit 3, and the lower part 5a of the mounting angle 5 is moved between the upwardly bent piece 4b of the fixing bracket 4 and the support 1. At the same time, the locking claw 4c at the tip of the bent piece 4b is engaged with a recess 5d provided in the lower part 5a of the mounting angle 5. Reference numeral 6 denotes a crosspiece such as a handrail, and the crosspiece 6 is placed on a receiving plate 5b projecting from the mounting angle 5 and is secured by tightening and fixing the receiving plate 5b, the crosspiece 6, bolts 7, and nuts 8.

[Function and effect of the idea]

As is clear from the above structure, the fixing metal fitting 4 is fitted into the lower slit 2 of the support 1 which has slits 2 and 3 cut at the top and bottom so as to fit into the slit 2, and is further fitted into the upper slit 3 along the support 1. Position the locking hook piece 5c on the inside of the mounting angle 5, and then lower the mounting angle 5 along the support 1, and connect the lower part 5a of the mounting angle 5 to the upwardly bent piece 4b of the fixing bracket 4 and the support 1. A recess 5 provided at the bottom of the mounting angle 5 by inserting it into the gap m between the
d and the locking claw 4c provided on the upwardly bent piece 4b are engaged and locked, and furthermore, the locking hook piece 5C positioned inside the upper slit 3 is locked to the lower edge of the slit 3 by lowering the mounting angle 5. Then, the crosspiece 6 is mounted on the receiving plate 5b of the fixed mounting angle 5, and the crosspiece 6 is fixed to the receiving plate 5b with the bolts 7 and nuts 8.

As mentioned above, the present invention is a fixing device that is bent into a shape that fits into the lower slit of the support column, which has slits at the upper and lower sides at intervals, and the end portion is bent upward with an insertion gap between it and the support column. Insert the metal fittings into the upper slit, and position the hook piece of the mounting angle, which has a receiving plate projecting laterally on the outside and a locking piece approximately matching the support plate thickness on the inside, and attach the hook piece to the upper slit. At the same time, insert and lock the lower part of the mounting angle between the upwardly bent pieces of the support and the fixing bracket, and then place the crosspiece on the receiving plate of the mounting angle and fix it with the tightening bracket. The mounting angle is secured in two places by a fixing fitting fitted to the support and a hook piece attached to the lower edge of the slit of the support, instead of tightening the conventional bolt at one place. Compared to mounting, it is stable without loosening or shifting, and it can be installed with one touch, so it is easier to install than by inserting and tightening the bolt while searching for the insertion hole. It also has the advantage of being cheaper than using bolts.
