Embodiment 1 FIG.
1 is a cross-sectional view showing a basic structure of a movable home fence apparatus 1 according to Embodiment 1 of the present invention.
The movable platform fence device 1 is installed along a side edge on the platform 4 and forms a fence with a train that stops at a fixed position on a track that extends to the side of the platform 4. The safety of passengers is ensured.
The platform 4 is formed in a substantially T-shaped cross section supported on the standing leg portion, and the side edge portion of the platform 4 protrudes to the line side extending to the side of the platform 4.
The platform 4 includes a slab portion 6 made of reinforced concrete and a panel portion 5 bonded to the upper surface of the slab portion 6 by a mortar portion 7 and embedded with anti-slip and tiles.

  The movable platform fence device 1 is composed of a door pocket fence and an openable / closable entrance door that appears and disappears along the side edge of the platform 4 from the door fence. The movable platform fence device 1 is provided with rectangular legs 2 at the lower portions on both the left and right sides of the door pocket fence when the track side is viewed from the platform 4 side. The movable platform fence device 1 is fixed to the platform 4 by screwing four mounting bolts 3 (two on the track side and two on the non-track side) to the pair of leg portions 2 respectively.

Mounting holes 8 are formed in the platform 4 corresponding to positions where the respective mounting bolts 3 are screwed. The depth of the mounting hole 8 penetrates the panel portion 5 and the mortar portion 7 from the upper surface and reaches the back of the slab portion 6, and has a strength that the platform 4 can withstand the load in the plane direction on the movable home fence device 1. The depth to be secured.
For example, when the thickness of the panel portion 5 is 30 mm and the thickness of the mortar portion 7 is 10 mm and the depth capable of securing the strength required for the slab portion 6 is 70 mm, the depth of the mounting hole 8 is 110 mm.
An adhesive female thread anchor (hereinafter abbreviated as female thread anchor) 10 shown in FIG. 2 is fixed and embedded in the mounting hole 8 with a filler 9.

The internal thread anchor 10 includes a cylindrical anchor body 30 having an internal thread 14 formed on an inner wall surface, and a disk-shaped receiving plate 13 secured to the upper portion of the anchor body 30 by caulking or the like (which may be welded or bonded). And. The depth of the female screw 14 is not necessarily required up to the lower end portion of the anchor main body 30.
The support plate 13 supports the load of the movable home fence device 1 and, when the leg portion 2 of the movable home fence device 1 is fixed to the platform 4 using the mounting bolt 3, the fastening force of the mounting bolt 3 is a panel.

When the filler 9 is solidified and the fixing portion 11 of the female screw anchor 10 is bonded to the slab portion 6 of the platform 4, the center line of the through hole of the leg portion 2 of the movable platform fence device 1 and the center line of the female screw hole 14 of the female screw anchor 10 are obtained. The movable home shelf device 1 is placed on the platform 4 so that.
Thereafter, the mounting bolt 3 penetrating the through hole of the leg portion 2 is screwed into the female screw hole 14 to fix the movable home shelf device 1 on the platform 4.

Thus, it is not necessary to process the fitting groove from which the panel portion 5 and the mortar portion 7 of the platform 4 are removed and the through-hole penetrating the slab portion 6 as in the prior art, and it is easy to use an electric drill or the like The mounting hole 8 can be formed in a short time, and the movable home fence apparatus 1 can be easily and quickly installed on the upper surface of the platform 4.
Further, the receiving plate 13 of the female screw anchor 10 is separated from the upper surface of the panel portion 5 of the platform 4, and the load of the movable home fence device 1 and the load when the leg portion 2 is tightened with the mounting bolt 3 are It is received by the receiving plate 13. Therefore, since the load after the movable platform fence apparatus 1 is installed on the platform 4 is not applied to the panel unit 5, it is possible to prevent the panel unit 5 from being broken or peeled off from the mortar unit 7. it can.

Furthermore, there is a case where the work until the female screw anchor 10 is inserted due to the work time during construction and the work of attaching the leg 2 of the movable home fence device 1 to the female screw anchor 10 with the mounting bolt 3 are performed on different days. is there.
Even in such a case, the female screw anchor 10 can be cured so that only a thin disc-shaped receiving plate 13 protrudes from the upper surface of the panel portion 5 of the platform 4 and hardly causes a step. Extra work such as installing an enclosure around the anchor 10 to prevent the passenger from approaching is not necessary, and it is possible to suppress the occurrence of a trip or fall of the passenger during commercial operation during curing.

  Further, since the lower space of the platform 4 is not related to the installation work of the movable platform fence device 1, it can be constructed even when there is a reinforcing steel material, a rack, a cable, or the like in the lower space of the platform 4.
