In this open state, the last glass plate 12 is similarly fitted from the indoor side to the upper and lower frames 5 and 7 in a blunt manner, and then the movable side frame member 18 is superposed on the fixed side frame member 17. By entering and moving, the outdoor side of the glass side edge portion fitting groove 9 is closed, and the side edge portion 12d of the glass plate 12 is fitted in the fitting groove 9, and the movable side frame member is in this fitted state. Claim that 18 is screwed to fixed side frame member 17 2 according to the mounting method of the handrail according to.

According to claim 3 , the glass mounting frame 14 and the aluminum joint frame 13 are fitted with watertight packings 19 and 20 for holding the outer peripheral edge of the glass plate 12 in a watertight manner, and the inner peripheral edge of the glass plate 12. The handrail attachment method according to claim 2 or 3, wherein caulking materials 21 and 22 for watertight sealing the portion are filled or applied.

  According to the first aspect of the present invention, the handrail main body is formed by setting up the handrail struts 1 on the parapet P of the veranda at predetermined intervals in the longitudinal direction and bridging the handrail heads 2 over the upper ends of these handrail struts 1. In the handrail attachment device formed by forming glass 3, a glass attachment frame 14 made up of glass upper frame 5, glass lower frame 7, and left and right glass frames 10, 11 is integrated with the outdoor side of handrail main body 3. Alternatively, the glass upper frame 5 is formed with a glass upper edge fitting groove 4 in communication with the glass upper frame 5 over substantially the entire longitudinal direction of the handrail body 3, and the glass lower frame 7 has the glass upper edge. A glass lower edge fitting groove 6 corresponding to the fitting groove 4 is formed in communication, and glass side edge fitting grooves 8 and 9 are formed in the left and right side frames 10 and 11. Edges 12a and 12b are the glass upper edge fitting groove 4 and the glass. The left and right side edge portions 12c and 12d of the glass plate 12 at both ends are fitted into the glass side edge portion fitting grooves 8 and 9 of the left and right side frames 10 and 11, respectively. As a result, a plurality of glass plates 12 are attached to the glass mounting frame 14 continuously in substantially the entire region of the handrail main body 3 in the longitudinal direction of the outdoor side. Since it is covered with the glass plate 12 provided continuously over substantially the entire longitudinal direction of the main body 3, the appearance is very good, and the glass plate 12 prevents the entry of wind and rain into the indoor side. You can open the room even when it rains.

  Moreover, since the glass plate 12 is attached to the glass mounting frame 14 by the fitting method as described above, the glass plate 12 is attached to the glass mounting frame 14 from the indoor side by a so-called annealing method. Since a scaffold for attaching the glass plate 12 to the outdoor side of the handrail main body 3 is not necessary, the construction cost is reduced accordingly.

  Moreover, since the aluminum joint frame 13 is arranged between the plurality of glass plates 12 adjacent to each other, the aluminum unique appearance is exhibited as compared with the case where the conventional rubber joint material is filled. The appearance of the finding surface of the handrail main body 3 is also good from this surface.

  Furthermore, the aluminum joint frame 13 is attached to the handrail body 3 so as to engage the side edges 12c and 12d of the glass plate 12, and the upper, lower, left and right four-week edges of the glass plate 12 are connected to the glass mounting frame 14. Since the aluminum joint frame 13 is engaged and held, only the upper and lower edges of the glass plate are engaged and held by the upper and lower frames, and a conventional rubber joint material is filled between the adjacent glass plates. Compared to the above, the attachment strength of the glass plate 12 to the glass attachment frame 14 is high, the durability against wind pressure is good, and if it is turned, the glass plate 12 can withstand wind pressure even if the wall thickness is thin. The glass plate 12 can be stably attached to the glass mounting frame 14.

In addition, since the glass plate 12 can be fitted and attached to the glass mounting frame 14 provided on the handrail main body 3 from the indoor side by a blunting method, a scaffold for attaching the glass plate to the outdoor side of the handrail main body is provided. There is no need to assemble, and the construction cost is reduced accordingly.

  Moreover, the aluminum joint frame 13 is used as a joint material between the adjacent glass plates 12 of the plurality of glass plates 12, and the aluminum joint frame 13 is made of aluminum on the locking claws 15 provided on the handrail support column 1. Since the latching claw 16 provided on the joint frame 13 is slid from one side in the longitudinal direction of the handrail main body 3 and is locked to the handrail main body 3, the aluminum joint frame 13 is also easily from the indoor side. It can be attached to the base plate, and no scaffolding is required. In this regard, in the past, joint materials made of rubber-based seal materials have required filling or coating work from the outdoor side to the joints of each glass plate, and a scaffold for the work has been required.

  By the way, after the upper and lower edge portions 12a and 12b of the glass plate 12 are fitted into the glass upper and lower edge portion fitting grooves 4 and 6 of the glass mounting frame 14 in a blunt manner, this is slid to one side, The front side edge 12c of the glass plate 12 is fitted into the glass side edge fitting groove 8, and subsequently, the plurality of glass plates 12 are arranged in order, and the upper and lower edges 12a, 12b thereof are glass upper and lower edge fitting grooves 4. , 6, and the glass mounting frame 14, and a plurality of glass plates 12 are continuously connected to the upper and lower glass edges 12 a and 12 b of the upper and lower frames 5, 7. Even if it can be fitted to the glass mounting frame 14 by being fitted to the glass mounting frame 14, the upper and lower edges 12a and 12b of the last glass plate 12 are tried to be fitted into the glass upper and lower edge fitting grooves 4 and 6. For example, as it is, the rear edge 12d of the glass plate 12 is connected to the side frame 11 of the glass mounting frame 14. It will not be able to fit in collision.

Therefore, in claim 2 , among the left and right side frames 10 and 11 forming the glass side edge fitting grooves 8 and 9, the glass side on which the rear end side edge 12d of the last glass plate 12 is fitted. The movable side of the side frame 11 that forms the edge fitting groove 9 can be moved back and forth from the fixed side frame member 17 and the fixed side frame member 17 so as to overlap the fixed side frame member 17. The frame side member 18 is formed, and the movable side frame member 18 is moved backward from the fixed side frame member 17 to the one side to open the outdoor side of the glass side edge fitting groove 9. Similarly, the glass plate 12 is fitted between the upper and lower frames 5 and 7 in an obtuse manner from the indoor side, and then the movable side frame member 18 is moved into the fixed side frame member 17 so as to overlap the glass. The outdoor side of the side edge portion fitting groove 9 is closed, and the fitting groove 9 is made of glass. 12 side edge portions 12 d can be fitted without colliding with the side frame 11, and then all the glass plates 12 are made of glass by screwing the movable side frame member 18 to the fixed side frame member 17. The mounting frame 14 can be fitted from the indoor side without hindrance by the dull method.

According to claim 3 , the glass mounting frame 14 and the aluminum joint frame 13 are fitted with watertight packings 19 and 20 for holding the outer peripheral edge of the glass plate 12 in a watertight manner, and the inner peripheral edge of the glass plate 12. Since caulking materials 21 and 22 for watertight sealing of the parts are filled or applied, rainwater enters the indoor side from between the glass mounting frame 14 or the aluminum joint frame 13 and the glass plate 12. There is nothing.
