Description

The present invention relates to an installation structure of a movable platform fence and the like.

The movable platform fence is a device that is installed at the end of the platform on the track side of the station platform and opens and closes the door according to the timing of getting on and off. There are various types of movable platform screen doors, but the sliding door type movable platform screen doors that slide and move the sliding door type movable door from the door pocket to move it back and forth are widely used. By installing a movable platform fence, it is possible to prevent the user from falling from the platform to the track side. Therefore, there are many cases where movable platform screen doors are installed not only in newly constructed stations but also on the platforms of existing stations.

By the way, the home fence has a considerable weight (for example, about 500 kg). Then, most of the weight acts locally on the floor surface of the platform through the standing portion (the door pocket portion corresponds to the sliding door type movable platform fence) erected on the platform. In addition, the lateral load created by installing a movable platform fence (for example, the load caused by leaning on a passenger, the wind pressure load when passing a train, the wind pressure load due to a meteorological phenomenon such as a typhoon, etc.) is also transmitted through the vertical part. It acts locally on the platform.

Various techniques have been proposed to deal with the increase in weight and lateral load associated with the installation of such movable platform fences. For example, Patent Document 1 proposes a method using a dedicated PC slab whose reinforcement arrangement and thickness are designed on the premise that the base plate for fixing the door pocket portion is fixed with bolts. Further, Patent Document 2 discloses a technique of fixing a concrete slab in which a portion for attaching a door pocket portion is prepared in advance on an embankment type platform with a lock bolt.

When installing additional movable platform fences, unlike installation on a new platform, there is a problem that special construction and labor are required, and there is a tendency to impair aesthetic harmony with existing equipment. May be a problem.
For example, when the method of Patent Document 1 is adopted for an existing platform, the upper part of the platform must be scraped by a considerable amount in order to install a PC slab. Further, since a plurality of PC slabs are continuously arranged at the end of the platform, reinforcement work for supporting the additional weight of the PC slab may be required in addition to the portion where the door pocket portion is installed. In addition, in order to maintain the aesthetic appearance, additional work such as laying tiles on the upper surface of the PC slab is required.

Further, when the method of Patent Document 2 is adopted, the concrete slab is installed only in the part where the door pocket portion is installed, so that the construction part for the entire platform can be relatively small as compared with the case where Patent Document 1 is adopted. Instead, local excavation of the platform will be essential.

Further, even when the method of Patent Document 2 is adopted, the platform to be installed must support the load including the weight of the concrete slab in addition to the weight of the movable platform fence, so that the reinforcement work There is no change in the point that is required.
As the load that the platform must support locally increases, the rock bolts that secure the concrete slab and similar structural elements are inevitably relatively large and numerous. Sometimes large diameter pipes have to be used as stanchions. On girder platforms, large diameter pipes will penetrate the end of the platform, which may require additional work to relocate cables and other equipment installed under the girder. In addition, since the construction site is limited, the appearance of the additional construction will be lost, and the sense of unity with the surroundings may be lost, which may spoil the aesthetic appearance of the entire platform.

It should be noted that such a problem is not limited to the sliding door type movable platform fence, but the same applies to the elevating type movable platform fence in which the elevating part provided with the movable fence and the rope-like elevating mechanism is fixed on the platform.

An object of the present invention is to provide a new technique for installing a movable platform fence on an existing platform.

The first invention for solving the above-mentioned problems is that the plate-shaped floor material laid on the foundation floor surface and the horizontal level are adjustablely installed in the recesses provided in the upper part of the plate-shaped floor material. It is a movable home fence installation structure including a base plate, a fixing portion for fixing the base plate and the plate-shaped floor material, and a standing portion of a movable home fence erected and fixed to the base plate.

According to the first invention, a recess is provided in a plate-shaped floor material to be laid as a new floor surface on the foundation floor surface, and a base plate is installed and fixed therein. Then, the erecting portion of the movable platform fence can be erected via the base plate.

According to the present invention, the weight of the movable platform fence is distributed and transmitted to the foundation floor surface of the platform via the base plate and the plate-shaped floor material. Therefore, the platform on which the movable platform fence of the present invention is installed need only be able to support this distributed load, and does not need to locally support a large load. If the installation destination is an existing platform, reinforcement work to locally support a large load (for example, reinforcement work such as installing a large-diameter pipe column through a girder platform as described above) becomes unnecessary. Adoption to existing platforms can also be done at low cost. In addition, the floor surface of the platform after the installation of the movable platform fence will be a new plate-shaped floor material, which is far more aesthetically pleasing than using a PC slab. In addition, additional work for aesthetic purposes, such as attaching tiles separately, may be performed, but it can be made unnecessary.

In the second aspect of the present invention, the base plate is temporarily connected to an adjuster bolt for adjusting the horizontal level and a jig for positioning the distance and height between the other base plate and the other base plate. It is a movable platform fence installation structure of the first invention which has a jig attachment part for detachably attaching.

According to the second invention, the plurality of base plates can be connected to each other via a jig, and the distance and height of the plurality of base plates can be appropriately adjusted. In particular, when a movable platform fence is additionally installed on an existing platform, appropriate installation work can be easily realized even if the existing platform cannot always maintain a flat floor surface.

A third invention is an intermediate plate-shaped flooring material laid between the plate-shaped flooring material on which the base plate is installed and the plate-shaped flooring material on which the other base plate is installed. The recess is not provided, and 2) an insertion hole for inserting the electric cable of the vertical portion and 3) an underfloor space communicating with the insertion hole for wiring the electric cable to the cable duct are formed. It is a movable home fence installation structure of the second invention further including an intermediate plate-shaped floor material having an underfloor space forming portion.

According to the third invention, in order to fix one standing portion, a plurality of plate-shaped flooring materials on which base plates are installed are installed at a distance, and an intermediate plate-shaped flooring material is also laid in the middle. By doing so, the appearance around the standing part can be unified.
In addition, since the electric cable can be routed to the cable duct using the underfloor space provided under the intermediate plate-shaped floor material, additional work such as providing a wiring space to the cable duct with the addition of the movable home fence Is no longer needed.

In a second or fourth aspect of the present invention, the upright portion is erected and fixed on the base plate and the other base plate in which the jig is mounted and positioned on the jig mounting portion. It is a movable platform fence installation structure of the third invention.

According to the fourth invention, one upright portion can be fixed to the platform with a plurality of plate-shaped flooring materials via a plurality of base plates. Since the weight of the movable platform fence can be distributed to a plurality of plate-shaped floor materials, it is possible to further reduce the reinforcement work associated with the additional installation of the movable platform fence from the viewpoint of load distribution.

A fifth invention is a fluid injection material in which the fixing portion is cured to closely fix the base plate and the plate-shaped floor material, and the base plate is vertically and vertically used to inject the injection material. It is a movable platform fence installation structure of any one of the first to fourth inventions which has a penetrating injection hole.

According to the fifth invention, the workability is excellent.

A sixth invention is the movable platform fence installation structure according to any one of the first to fifth inventions, wherein the upright portion is a door pocket portion that supports and opens and closes the door.

According to the sixth invention, it is possible to realize a sliding door type movable platform fence that exhibits the same effect as that of any one of the first to fifth inventions.

The seventh invention is a step of laying a plate-shaped floor material on the foundation floor surface, and installing a base plate whose horizontal level can be adjusted in a recess provided in the upper part of the plate-shaped floor material to adjust the horizontal level. This is a movable home fence installation method including a step of fixing the base plate and the plate-shaped floor material, and a step of erecting and fixing a standing portion of the movable home fence to the base plate.

According to the seventh invention, the same effect as that of the first invention can be obtained.

It has a nut 63 for tightening the retaining bolt 62 after level adjustment.

Further, in the above embodiment, the movable platform fence 10 is a sliding door type and the door pocket portion 13 is an upright portion, but the present invention can be similarly applied to an elevating type movable platform fence. In that case, the erecting portion corresponds to a portion that is erected and fixed on the upper surface of the platform 7 by incorporating an elevating door and a mechanism portion that elevates and lowers the cord-like body.

Further, in the above embodiment, an example in which a movable platform fence is installed along with the raising work of the existing platform is shown, but the plate-shaped floor material 30 is installed after scraping the upper surface of the existing platform 7. It is also possible to install a movable platform fence.

Further, in the above embodiment, the cable duct 42 is arranged under the Braille tile band 40, but it can also be provided under the platform 7. In that case, even if the through hole for passing the electric cable 16 from the platform to the bottom of the platform is not provided near the position of the insertion hole 34 provided in the intermediate plate-shaped floor material 30b, electricity is supplied via the underfloor space 9. The cable 16 can be arranged freely.
