れる。Problems to be Solved by the Invention] However, according to the conventional upright structure shown in FIG. Since multiple fastening bolts (20, etc.) are used in close proximity to each other so that the handrail column 3 can absorb the necessary strength and obtain the necessary strength, the ends of the fastening bolts (20, etc.) are exposed to the outside of the parapet. As a result, expansion due to corrosion of the fastening bolts 20 and the like occurs at a close position, which poses a problem that there is a risk of destroying the concrete ground or mortar. Furthermore, as the number of fastening bolts 20 etc. driven into the parapeller l-1 increases, the probability of interference with the reinforcement arranged in the parapeller l-1 increases, making it difficult to obtain the strength of the column support member 2. There have been many problems in that drilling holes from the side of the parapet 1 is difficult, and the workability is also difficult. Furthermore, according to the conventional upright structure shown in FIG.
Since the column support member 2 is embedded in the parapet 1, there is a problem that rusting of the column support member 2 may induce cracks from inside the concrete or mortar. There have been many problems in that the welding work between the handrail support 3 and the handrail support 3 is extremely complicated, and it is impossible to replace the handrail support 3 again. The present invention has been made in order to solve the above-mentioned problems, and has little risk of inducing cracks in concrete or mortar, has sufficient installation strength, and can be easily removed. The purpose of this invention is to provide a simplified erection structure for handrail supports. [Means for Solving the Problems] According to the present invention, the above object is to provide a single embedded anchor installed vertically on a parapet 1'' as shown in FIG. 1 corresponding to the embodiment. 4, a connecting member 5 disposed on the upper surface of the parapet 1 and formed by connecting a plurality of piece-like members 50 to each other so as to be vertically slidable at the side wall portion is inserted, and this connecting member 5 connects the lower end of the handrail support 3. This is achieved by providing an erecting structure for the handrail support that is fixed to the handrail support.

6 is a built-in hole drilled on the top surface of this paravet l, 4
The lower end of the parapet 1 is buried in this built-in hole 6.
This figure shows an embedded anchor installed upright, and a screw 40 is carved into the upper end side of this embedded anchor 4. The connecting member 5 according to this embodiment includes three piece members 50
It is constructed by connecting ゜50.50, and the central piece-shaped part +
An insertion hole 5I having an inner diameter approximately equal to the outer diameter of the embedded anchor 4 is bored in the center of A50. Further, on both side walls of the central piece-like member 50, substantially dovetail-shaped sliding protrusions 53 are formed which fit into the dovetail grooves 52 of the other piece-like members 50, 50, so that they can be combined with each other. The respective piece-like members 50, 50.50 are arranged such that their relative positions in the vertical direction can be changed with respect to each other. Next, a procedure for installing a handrail on a parapet l using the handrail support erecting structure according to the present invention will be explained. As shown in FIG. 4, this handrail consists of handrail caps 70 installed between the upper ends of handrail supports 3 erected at appropriate intervals.
Below, there are a plurality of balusters 73. between the upper and lower chord members 71.72.
It is constructed by attaching a balustrade unit 7 formed by constructing a parapet 73. First, as shown in Figures 1 and 2, a hole 6 is drilled in the parapet 1, and the The filling hole 6 is filled with epoxy resin 60 or mortar, and the embedded anchor 4 is planted vertically. Next, when the connecting member 5 is inserted from the top of the embedded anchor 4, each piece-like member 50 is assembled as shown in FIG.
They slide against each other under their own weight and are held on the top surface of the parapet 1 in a state that matches the inclination angle of the top surface of the parapet 1. In this state, as shown in FIG. 3, after driving the pin 54 that passes through the sliding protrusion 53 from the side wall of the piece-shaped member 50 located on the outside, tightening is done by tightening the nut 41 (J
By doing so, the connecting member 5 is firmly fixed. After that, if necessary, as shown by chain lines in FIG. 2, mortar 10 or the like is applied to the contact area between the connecting member 5 and the upper surface of the parapet I, and the lower end of the handrail post 3 formed in a hollow shape is connected. It is sufficient to fit the connecting member 5 onto the outside of the member 5, and to connect and fix the connecting member 5 and the handrail support 3 using the fixing screws 30. In the above embodiment, as shown in FIG.
A lower chord member 72 constituting the baluster unit 7 using
Although the lower chord member 72 is collinear with the bracket 31 for fixing to the handrail post 3, it goes without saying that the bracket 31 may be fixed separately, and the handrail post 3 and the connecting member By appropriately adjusting the connecting portion with the parapet 5, it is possible to cope with changes H1 and H2 in the height of the parapet 1, as shown in FIG. 6 to 8 show a second embodiment of the present invention, in which the connecting portion H
'5 is constructed from two piece-shaped parts + I'50.50. In this example, one piece-shaped portion tl
A substantially dovetail-shaped sliding protrusion 53 is protruded from one side wall of the '50, and as in the first embodiment described above, it slides with the dovetail groove 52 of the other piece-shaped member 50. Fit freely, and as appropriate.
It is possible to fix it in a relative position using a pin 54. Furthermore, the insertion hole 51 of the connecting member 5 in this embodiment is
The short axis 7S is approximately the same as the diameter of the embedded anchor 4, and the long axis LL is slightly longer than the diameter of the embedded anchor 4.It is an ellipse whose short diameter 7S is slightly longer than the diameter of the embedded anchor 4. It is possible to adjust. Furthermore, as shown in FIGS. 6 and 8, a screw hole 55 is provided at the upper end of the sliding protrusion 53 of one piece-like member 50.
is formed, and an adjustment pole (5) passes through the support plate 56 placed on one end of the other piece-like member 50.
7 is screwed in. Therefore, according to this embodiment, after the connecting member 5 is inserted into the embedded anchor 4 erected in the parapet, the evoquino resin is inserted into the gap between the embedded anchor 4 and the insertion hole 5I of the connecting member 5. 60 or mortar, etc., and adjust the position in the direction of the arrow in Fig. 6, tighten the embedded anchor 4 (fasten the nut 4I to fix one piece-shaped part + A50, and then tighten the adjustment bolt 5
7 by tightening (', l) the other piece-shaped part t1
After sliding the bottom surface of the parapet 50 to a position where it accurately abuts the top surface of the parapet 1, the pin 54 can be driven in and the connecting member 5 can be fixed in place. [Effects of the Invention] As is clear from the above explanation, according to the handrail support erection structure according to the present invention, the connecting part side is fixed to one embedded anchor vertically installed on the parapet, and this Since the lower end of the handrail column is fixed to the connecting member, there is no need to drive multiple metal members, that is, anchors, into the parapet as in the past. Therefore, the probability of interference with the reinforcing bars inside the parapet is reduced, and work efficiency can be improved, and 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 place multiple exposed metal parts into the concrete ground, i.e., inside the parapet, so there is no need to place multiple exposed metal parts into the concrete ground, i.e., inside the parapet. It can be prevented. Furthermore, the connecting member (J) is fixed on the top of the parapet, and the load applied to the handrail is supported by the parapet and the embedded anchor, so the load on the embedded anchor can be reduced. The overall strength can be increased.
