Description

[Detailed description of the invention] The present invention relates to a handrail mounting structure, and in detail, the lower frame core 1a is formed into a U-shaped cross section with an open top surface, and the lower frame extensions 1
b is formed into a U-shaped cross section with an open bottom, and the lower frame extension 1b
The inner dimension W of the lower frame core 1a is approximately equal to the outer dimension W' of the lower frame core 1a, and the inner dimension height h of the lower frame stretcher 1b is smaller than the lower frame core 1.
The lower frame 1 is formed by lowering the external height h' of a, and covering the lower frame core 1a with a lower frame stretcher 1b having a handrail 6 integrally erected on the upper surface so as to be able to change the vertical sliding position, Installation of a handrail in which one side piece 4a is fixed to a mounting surface such as the side surface of the vertical frame 2 or the wing wall 3, and the other side piece 4b of the fixing hardware 4 is fixed to the inner surface of the end of the lower frame core 1a. It is related to the structure.

Conventionally, as shown in FIGS. 1 and 2, a square cylindrical lower frame 1' is butted against the side surface of the vertical frame 2 or the arm wall 3, and one side piece of the L-shaped fixing hardware 4' is attached. 4a' is fixed to the upper surface of the lower frame 1' with screws 5a', and the other side piece 4b' of the fixing hardware 4' is fixed.
was fixed to the side wall of the vertical frame 2 or the wing wall 3 with screws 5b.

Therefore, the fixing hardware 4' was exposed to the outside, resulting in an unsightly appearance.

Furthermore, the ends of the handrail bars 6 erected on the upper surface of the lower frame 1' were in the way, making it difficult to drive screws to attach the fixing hardware 4'.

Furthermore, due to assembly errors, it was not possible to change the length of the handrails used to support the cap, resulting in poor assembly performance.

The present invention was developed in view of the drawbacks of the conventional example of a diagonal top.The purpose of this invention is to prevent the fixing hardware from being exposed to the outside, give it an excellent appearance, and make it easy to fix the bottom frame with screws. Moreover, it is possible to change the substantial length of a handrail frame for supporting a hat due to assembly errors, and to provide a handrail mounting structure that is easy to assemble.

The present invention will be explained in detail below with reference to the accompanying drawings.

The handrail mounting structure of the present invention is implemented when installing the handrail 7 between the vertical frames 2 or between the vertical frames 2 and the wing walls 3 on a balcony A as shown in FIG. 7, for example,
The handrail 7 has a plurality of handrail bars 6 erected between a cap 8 and a lower frame 1.

That is, as shown in FIG. 3, the lower frame 1 is composed of a lower frame core 1a having an open top and a U-shaped cross section, and a lower frame extension 1b having a U-shaped cross section and an open bottom. The length of the core 1a is the same, and the inner width W of the lower frame stretcher 1b is the same as that of the lower frame core 1a.
The inner dimension height h of the lower frame core 1a is equal to the outer dimension width W', and the inner dimension height h of the lower frame core 1a is greater than the outer dimension height h' of the lower frame core 1b.
There is a distance l between the upper end of the lower frame core 1a covered with the lower frame core 1a and the ceiling surface of the lower frame stretcher 1b.

Moreover, a plurality of handrail bars 6 are integrally erected on the upper surface of the lower frame extension 1b, and a handrail 7 is constituted by integrally suspending a cap 8 on the upper end of the handrail bars 6.

Therefore, during construction, first, one side piece 4a of the L-shaped fixing hardware 4 as shown in FIG. As shown in FIG. 3, the inner surface of the lower frame core 1a is attached to the other side piece 4b of the fixing hardware 4 with screws 5b, and the lower frame stretcher 1b integrally provided with the handrail bar 6 etc. is attached to the bottom frame. The lower frame core 1a and the fixing hardware 4 are hidden by covering the child 1a, and the lower frame extension 1b and the lower frame core 1a are individually identified with screws or the like.

Of course, the cap 8 can also be attached to the vertical frame 2 and the wing wall 3 by appropriate means.

As described above, the present invention consists of a lower frame core with an open top surface covered with a lower frame stretcher to form a lower frame, and a fixing hardware with one side piece fixed to a mounting surface such as a side wall of a vertical frame or a wing wall. Since the other side piece is fixed to the inner surface of the end of the lower frame core, the fixing hardware is located within the lower frame and is not exposed to the outside, giving a clean appearance and a sense of luxury and high quality. There is an advantage that it can be done.

In addition, the lower frame is divided into a lower frame core and a lower frame extension with a handrail erected on the top surface, and the lower frame core is fixed to the mounting surface with fixing hardware, so the lower frame extension is fixed. The construction can be easily carried out since the handrails installed on the wall do not get in the way.

In addition, the outer height of the lower frame core is lower than the inner height of the lower frame nobutsu, and the bottom frame nobutsu, which has handrail bars integrally erected on the top surface, can be placed over the bottom frame so that the vertical slide position can be changed freely, giving the lower frame a shapely appearance. Therefore, in the standard installation state in which the lower edge of the bottom frame brace and the bottom surface of the bottom frame core are approximately aligned, the length of the handrail bar integrally erected on the bottom frame brace is set at a specific height. If it is not possible to reach the kasagi that is provided, slide the bottom frame nobutsu upwards relative to the bottom frame core to raise the handrail bar, or if the length of the handrail bar is long, it will hit the kasagi provided at a specific height. In some cases, by deeply covering the lower frame core with the lower frame core and lowering the handrail crosspiece, the handrail crosspiece can be brought into close contact with the capboard installed at a specific height. After attaching the frame core to the vertical frame or side wall, the height of the handrail bar can be adjusted, and the installation of the lower frame core to the vertical frame, etc. from the height of the handrail bar can be done in a timely manner. There is no need to take it out and install it with high precision, which has the advantage of greatly improving the ease of assembling the balcony.
