Description

[Detailed explanation of the idea]

[Industrial Field of Application] This invention relates to handrails attached to balconies, for example, and particularly to improving the mounting strength thereof. [Prior art] Fig. 4 is an explanatory diagram of a conventional handrail attachment part.
In the figure, 2 is a weir wall, 4 is an attachment member attached to the upper part of this weir wall, and 6 is a handrail body attached to this attachment member. The mounting member 4 consists of a base 8 having a substantially U-shaped cross section and a support 10 vertically mounted on the base.
It is attached by fitting over the top of the body and fixing it with bolts and nuts 12. The conventional handrail is constructed as described above, and when a load is applied in the direction of tilting down the handrail body 6, the handrail body 6
Since it is supported by the weir wall 2 via the mounting member 4, the handrail body 6 does not fall down. [Problems to be solved by the invention] In the conventional handrail as described above, safety was ensured as long as the load applied to the handrail body 6 did not exceed a predetermined value. The purpose of this invention is to obtain a handrail that further ensures safety even if the load applied to the handrail body exceeds the above-mentioned predetermined value. [Means for solving the problem] The handrail according to this invention is constructed by arranging reinforcing bars in the weir wall so as to pass through them upward, and attaching a mounting member to the upper surface of the weir wall by welding to the reinforcing bars. The handrail body is attached to this attachment member by welding. [Function] In this invention, the mounting member is attached to the upper surface of the weir wall by welding to the reinforcing steel, and the handrail body is further welded and attached to the mounting member, so that the load applied in the direction of tilting the handrail body is not guaranteed in the conventional method. Even if the handrail exceeds a predetermined value, the handrail body will be prevented from falling down to a value greater than or equal to this value. [Embodiment] Figures 1A and 1B are explanatory diagrams showing an embodiment of this invention, in which 2 is a weir wall erected at the edge of a balcony, and 14 is a weir wall vertically extending through the weir wall. A plurality of reinforcing bars are arranged, 4 is a mounting member attached to the upper surface of this weir wall, and 6 is a handrail body erected via this mounting member. The mounting member 4 consists of a base plate 8 and a column 10 mounted perpendicularly to the base plate.
are welded and fixed to the reinforcing bars 14, as shown in FIG. 1B. The handrail body 6 is erected by inserting a column 10 into a support 16. In the handrail configured as described above, the weir wall 2
The reinforcing bars 14 placed inside increase the strength of the weir wall 2. Therefore, even if the load applied in the direction of tilting the handrail main body 6 exceeds a predetermined value guaranteed conventionally, the handrail main body 6 will be prevented from falling to a value equal to or higher than this value. Experimental examples Handrail A explained in the prior art, handrail B explained in the embodiment of the present invention, handrail C having a structure of another embodiment of the present invention shown in FIG. 5, and still another structure of the present invention shown in FIG. Regarding the handrail D of the structure of the example,
A destructive experiment was conducted using the method shown in Figure 2. In the figure, 18 is an anchor as a type of reinforcing bar, 20
is a reinforcing pipe, 22 is a hydraulic jack, 24 is a load detector, 26 is a displacement measuring device, 28 is a mounting base, and in the weir wall 2, handrails A, B, and C are ALC boards, and handrail D is
consists of RC blocks. As a result of the above experiment, the relationship between the load and displacement of each handrail is as shown in Figure 3, and the breaking load of each handrail is

[Effect of idea]

As explained above, this invention is designed so that even if the load applied in the direction of tilting the handrail body exceeds a predetermined value that is conventionally guaranteed, the handrail body will be prevented from collapsing until it exceeds this value. Furthermore, it has the effect of ensuring its safety.

[Brief explanation of the drawing]

Fig. 1 is an explanatory diagram showing one embodiment of this invention, Fig. 1A is the state before installation, Fig. 1B is the state after installation, Fig. 2 is an explanatory diagram showing the experimental method, and Fig. 3 Figure 4 is a graph showing the load-displacement curve.
The figure is an explanatory diagram of a conventional handrail, and FIGS. 5 and 6 are explanatory diagrams of a handrail having a structure that constitutes another embodiment of this invention. In the figure, 2 is a weir wall, 4 is a mounting member, 6 is a handrail body, 8 is a base plate, 10 is a pillar body, 14
is a reinforcing bar, and 16 is a support. Note that the same reference numerals in each figure indicate the same or corresponding parts.
