However, according to the conventional standing structure shown in FIG. In order to obtain the required strength, multiple fastening bolts 20, etc. are used in close proximity to each other, so the end portions of the fastening bolts 20, etc. are driven into the parapet 1 with their ends exposed to the outside, resulting in the fastening being difficult. There is a problem in that expansion due to corrosion of the bolts 20 and the like occurs at close positions, which may destroy the concrete or mortar. Furthermore, as the number of fastening bolts 20 etc. driven into the parapet 1 increases, the probability that they will interfere with the reinforcement arranged inside the parapet 1 increases, making it difficult to obtain the strength of the column support member 2, and However, there were many problems in that the drilling work had to be done from the side of the parapet 1, making the work difficult. Furthermore, according to the conventional standing structure shown in FIG. 8, since the column support members 2 are embedded in the parapet 1, rusting of the column support members 2 may induce cracks from inside the concrete ground or mortar. There is a problem that parapet 1
There were many problems in that the work required for chiseling, curing, and welding between the post support member 2 and the handrail post 3 was extremely complicated, and it was impossible to replace the handrail post 3 again. The present invention has been made to solve the above problems, and has a method that reduces the risk of inducing cracks in concrete or mortar, provides sufficient installation strength, and simplifies the installation work. The purpose is to provide an upright structure for handrail supports.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is an explanatory view showing the upright structure of a handrail support according to the present invention. In the figure, 1 is a parapet formed on the outer peripheral edge of the balcony, 10 is a built-in hole drilled in the upper surface of this parapet 1, and 4 is a parapet whose lower end is buried in this built-in hole 10 and is erected on top of the parapet 1. This figure shows an embedded anchor 4, and a screw 40 is cut into the upper end side of this embedded anchor 4. As shown in FIGS. 1 and 2a, the connecting member 6 is a box-shaped body with an anchor insertion hole 60 formed in the center. After the embedded anchor 4 is inserted into the anchor insertion hole 60, the upper end is opened. Tightening nut 42
It is fixed to the embedded anchor 4 by tightening. In addition, as the connecting member 6, in addition to the one shown in FIG. 2a, as shown in FIG. 2b, two members 61,
62 connected together, or as shown in FIG. The position in the direction may be adjustable. On the other hand, the reinforcing member 5 is embedded by generating a moment XY that counteracts the bending moment Pl generated at the interface between the embedded anchor 4 and the parapet 1 when a force is applied in the direction shown by the arrow P in FIG. This is for reinforcing the anchor 4, and as shown in FIG. 1, a projecting piece-shaped pressure contact part 53 is formed on both outer sides, and an anchor insertion hole having a diameter approximately equal to the diameter of the anchor 4 is embedded in the center part. 50
It has a substantially I-shape in plan view. In this way, by applying a compressive load at point a in the figure and applying a tensile load to the embedded anchor 4, the embedded anchor 4 is made to work effectively in terms of strength. Moreover, if the distance X is made longer, the load Y becomes smaller, and the handrail support 3 and the embedded anchor 4 can be made more efficient in terms of load. Note that the top surface 51 and bottom surface 52 of this reinforcing member 5 are parallel in FIG. The intersecting plane has an intersecting angle θ matching this inclination angle. Next, a procedure for installing a handrail on the parapet 1 using the handrail support erecting structure according to the present invention will be explained. As shown in Figure 5, this handrail has three handrail supports.
A handrail unit 7, which is formed by installing a plurality of handrails 73, 73... between upper and lower chord members 71, 72, is attached below the handrail cap 70 installed between the upper ends. As shown in the figures and FIG.
Plant it vertically. Next, embedded anchor 4
After inserting the reinforcing member 5 and the connecting member 6 from the top, the reinforcing member 5 and the connecting member 6 are firmly fixed in a laminated state by tightening the tightening nut 42. After that, the lower end of the hollow handrail post 3 is fitted onto the connecting member 6, the connecting member 6 and the reinforcing member 5 are tightly attached, and the fixing screws 6
3 to connect and fix the connecting member 6 and the handrail support 3. In addition, in this embodiment, the fixing screw 63
The lower chord member 7 constituting the baluster unit 7 is
2 and a bracket 74 for fixing this lower chord member 72 to the handrail post 3 are fastened together, but it goes without saying that the bracket 74 may be fixed separately. and connecting member 6
By appropriately adjusting the connecting part with the parapet 1 , as shown in FIG.
It can also support H2 .

As is clear from the above explanation, according to the handrail support erection structure according to the present invention, the reinforcing member and the connecting member are fixed to one embedded anchor vertically installed on the parapet, and the connecting member Since the lower end of the handrail support post is fixed by the above, it is no longer necessary to drive a plurality of metal members, that is, anchors, into the parapet as in the past. Therefore, the probability of interference with reinforcing bars inside the parapet is reduced, and work efficiency can be improved.
Furthermore, the durability of the parapet can be improved and the area around the embedded anchor can be reinforced. In addition, unlike conventional methods, there is no need to drive multiple exposed metal members into the concrete ground, i.e., inside the parapet, so it is possible to prevent cracks in the concrete due to corrosion and expansion of metal members in close proximity to each other. can. Furthermore, a reinforcing member is placed on the upper surface of the parapet so as to abut the lower end of the pressure welding part formed on the outside of the parapet, and a single embedded anchor is inserted through the center of this reinforcing member and the connecting member positioned above the reinforcing member. At the same time, the handrail support is fitted onto at least the upper end side of the reinforcing member and the connecting member to bring the outer surface of the reinforcing member and the connecting member into close contact with the inner wall of the handrail support, thereby acting on the handrail support. In response to the load, the required strength of the handrail column can be obtained by receiving a compressive load at the lower end of the reinforcing member and a tensile load using the embedded anchor, increasing the overall strength. can be increased.
