Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 to 3 show a handrail support erecting structure according to a first embodiment of the present invention. In the figure, 1 is a parapet formed on the outer peripheral edge of the balcony, 6 is a built-in hole drilled in the upper surface of the parapet 1, and 4 is a parapet erected on the parapet 1 with its lower end buried in the built-in hole 6. This is the embedded anchor 4.
A screw 40 is cut into the upper end of the holder. The connecting member 5 according to this embodiment is constructed by connecting three piece members 50, 50, 50, and the central piece-like member 50 has an inner diameter approximately equal to the outer diameter of the embedded anchor 4 at the center thereof. An insertion hole 51 is bored. Further, on both side walls of this central piece-like member 50, substantially dovetail-shaped sliding protrusions 53 that fit into the dovetail grooves 52 of the other piece-like members 50, 50 are formed, so that they can be combined with each other. Each piece-like member 5
0, 50, and 50 are arranged so that their relative positions in the vertical direction can be changed. 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 FIG. 4, this handrail consists of a plurality of handrails between upper and lower chord members 71 and 72 below a handrail cap 70 constructed between the upper ends of handrail supports 3 erected at appropriate intervals. It is constructed by attaching a baluster unit 7 which is formed by erecting children 73, 73..., and first, as shown in FIGS. 1 and 2, a hole 6 is drilled in the parapet 1, This installation hole 6 is filled with epoxy resin 60 or mortar, and the embedded anchor 4 is installed vertically.
Next, when the connecting member 5 is inserted from the top of the embedded anchor 4, each piece-like member 50 slides against each other under its own weight, as shown in FIG. and is held on the upper surface of the parapet 1. In this state, as shown in FIG.
After driving a pin 54 through the sliding protrusion 53 from the side wall of the connector 5, the connecting member 5 is firmly fixed by tightening the tightening nut 41. After that, if necessary, as shown by the chain line 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 1, 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 addition, in order to avoid the need to cut the lower end of the handrail support 3 to match the inclination of the parapet 1, when the handrail support 3 is in a fixed state, there is an appropriate gap between the lower edge of the handrail support 3 and the top surface of the parapet 1. A distance h is provided. In the above embodiment, as shown in FIG. 1, fixing screws 30 are used to attach the lower chord member 72 constituting the baluster unit 7 and the bracket 31 for fixing the lower chord member 72 to the handrail post 3. Although the brackets 31 are fastened together, it goes without saying that the brackets 31 may be fixed separately, and by appropriately adjusting the connecting portion between the handrail support 3 and the connecting member 5, the brackets 31 can be fastened together as shown in FIG. Thus, changes in height H 1 and H 2 of the parapet 1 can also be accommodated. 6 to 8 show a second embodiment of the present invention,
The connecting member 5 is composed of two piece-like members 50, 50. That is, in this embodiment, a substantially dovetail-shaped sliding protrusion 5 is provided on one side wall of one piece-like member 50.
3 is provided in a protruding manner, and similarly to the first embodiment described above, it can be slidably fitted into the dovetail groove 52 of another piece-shaped member 50 and fixed using a pin 54 at an appropriate relative position. It's like that. In addition, the insertion hole 51 of the connecting member 5 in this embodiment is an ellipse whose short axis LS is approximately the same as the diameter of the embedded anchor 4 and whose long axis LL is slightly longer than the diameter of the embedded anchor 4. The installation position of the member 5 can be finely adjusted during the erection work. Furthermore, the sliding protrusion 5 of one piece-like member 50
As shown in FIG. 6 and FIG.
An adjustment bolt 57 passing through is screwed. Therefore, according to this embodiment, the connecting member 5 is attached to the embedded anchor 4 erected on the parapet 1.
After inserting the epoxy resin 6 into the gap between the embedded anchor 4 and the insertion hole 51 of the connecting member 5.
After filling with zero or mortar or the like and adjusting the position in the direction of the arrow in FIG. 6, fasten the tightening nut 41 to the embedded anchor 4 to fix one piece-like member 50, and then tighten the adjustment bolt 57. After sliding the bottom surface of the other piece-like member 50 to a position where it accurately contacts the top surface of the parapet 1, the pin 54 can be driven in to fix the connecting member 5 in a predetermined position.

As is clear from the above description, according to the handrail post erection structure of the present invention, a connecting member is fixed to one embedded anchor vertically installed on the parapet, and this connecting member is used to erect the handrail post. Since the lower end is fixed, there is no need to drive a plurality of metal members, ie, anchors, into the parapet as in the conventional case. 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, the connecting member is fixed on the top surface 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, and the overall can increase the strength of
