Description

[Detailed description of the invention] (Industrial application field) This invention relates to a sliding platform for large MM objects.

(Prior Art and Problems) In recent years, all-weather roofed stadiums that cover the entire surface of the field have been attracting attention in architectural structures for athletic events such as baseball stadiums, which are large space structures.

However, since this type of stadium accommodates tens of thousands of spectators, special consideration must be given to ventilation. For example, if an air membrane structure is adopted, ventilation will be difficult due to the tightness of the interior. Becomes a female.

On the other hand, with conventional I-construction, which uses a fixed lath structure roof and a movable roof that opens and closes the central part of the roof, partially opening the roof depending on the weather, the above-mentioned ventilation problem does not occur. do not have.

However, the movable roof must be moved by some means, which causes the following problems because it is heavy.

As a general means of transportation, for example, tracks and wheels are usually used because they are simple, but with this means, the load is received by line contact between the tracks and the wheels, so the concentration of V7 weight becomes extremely large, making it difficult to move smoothly. There is a habit of using the term ``movement''.

Therefore, it is conceivable to provide a large number of wheels in order to distribute the load, but this would require more time for assembly and maintenance, resulting in a significant economic disadvantage.

This invention was made to solve these problems.
The object of the present invention is to provide a simple moving platform for large and small objects, which enables smooth movement by dispersing and receiving the load of manual objects with a relatively compact structure.

(Means for solving and overcoming the problems) In order to achieve the above object, the present invention provides a movable platform for large and small borrowed objects, such as a movable roof that partially opens and closes a dome roof, which is installed in the direction of movement of the movable platform. A rail with a circular cross section, a sliding plate that is substantially perpendicular to the rail and in contact with its outer periphery in a planar manner, and the sliding plate is held! It is characterized by comprising a frame on which the large and small hanging objects are placed.

(Embodiments and Effects) Below, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIGS. 1 to 5 show an embodiment of a large l fM sliding platform 10 according to the present invention.

The J moving table 10 shown in the figure is used, for example, in a retractable dome roof related to Japanese Patent Application No. 60-127089 filed by the present applicant, and will be explained using the dome roof of the same application as an example.

Figure 1 shows an overall plan view of the dome roof. In the figure, the periphery of the dome roof is a fixed roof 1, and a circular opening 2 in the center is connected to six petal-shaped movable roofs. roof 3a
It opens and closes at ~3F. C1 each petal-shaped roof 38~
1 In points (P1 to P6) of 3f are pivoted to the fixed roof 1 so that they can rotate in the direction of the arrow.

The movable platform 10 moves to the other vertices (Q,
~Qs) and the fixed roof 1, and the movable roof 38
Fixed roof 1 on fixed roof 1 along the moving direction of ~3f
Along the curved surface of and b, the pivot points P of the movable roofs 3a to 3f
, ~ A rail 12 with a circular cross section bent in an arc shape centered on P6 is laid, and a sliding plate 14 is attached to the outer circumferential surface of the rail 12 in a plane perpendicular to its longitudinal direction, and a sliding plate 12 is installed. 1
4 and an underframe 16 on which the movable roofs 3a to 3f are placed.

Furthermore, in this embodiment, the movable base 10 includes a pair of movable bases 10.10 having the same configuration arranged along the longitudinal direction of the rail 12, and a connecting fitting 11 and two bolts 13.137' [movable base 10.10]. i! attached to .10! ! Although the example is shown in which the table is connected by the connecting frames 15, 15, etc., it can also be constructed by one moving table 1o, or by using the above-mentioned connecting fitting 11.
Three or more movable platforms 10 may be connected together, for example.

As the rail 12, for example, a hollow steel pipe with a predetermined outer diameter is used due to its simplicity and ease of bending, and the sliding plate 14 is made of a member with a small friction coefficient such as a high molar or a differential. The rail 12 is formed into a band shape that covers approximately 1/3 of the outer peripheral surface of the rail 12.
Two sheets are arranged on each movable table 1o at predetermined intervals along the longitudinal direction.

The underframe 16 is supported by a pair of sliding legs 20° 20 that hold each sliding plate 14 with a protective plate 18 interposed therebetween, and by penetrating both ends of each sliding leg 20, 20. The main frame 22 has an inner shape with openings on the upper and lower surfaces, and a core plate holder 24 that covers the upper surface of the main frame 22. The sliding plate 14 and the protection plate 18 are interposed between this curved portion and the outer periphery of the rail 12.

There are two sliding legs 2 between the sliding legs 20 and the core plate holder 24.
Bin 2 is attached to the main frame 22 so that it spans between 0.20 and 0.20.
An equalizer 28 pivotally mounted at 6 is interposed,
B] The upper end of the lie 1128 is connected to the connecting frame 15 and the core plate holder 2.
The bolt 13 is in contact with the lower end of the bolt 13, which is attached through the bolt 4.

On the other hand, two coil springs 30 and 30 are interposed between the connecting frame 15 and the core plate holder 24, centering on the bolt 13.

A member not indicated by the reference numeral 32 in the figure is a plug attached to the end of the sliding leg member 20, and can slide in the direction of the arrow shown in FIG.

Furthermore, after bending the rail 12, for example, eaves concrete 34 can be poured into the inside of the rail 12 to increase the surface pressure strength. + with face plate 14? ! Further reduce gaps and improve corrosion resistance! Of course, it is also possible.

Now, in the movable table 10 configured as described above, the load placed on the connecting frame 15 is transmitted to the equalizer 28 via the bolts 13, divided by the equalizer 28, and then It is transmitted to the sliding face plate 14 via the moving leg (A20), and the sliding face plate 14 is in adhesive contact with the rail 12 on all sides.
This adhesive surface distributes the load and supports it.

Therefore, unlike conventional moving means, the load is not concentrated, and the sliding movement of the moving platform 10 can be smoothly performed even by manual operation.

In addition, two sliding face plates 14.14 are held by a swingable equalizer 28 and arranged in the longitudinal direction of the rail 12, and one sliding face plate 14.14 is placed on the right 4. Since the two movable platforms 10.10 are connected in the same way in the longitudinal direction, it is possible to absorb and cover even small horizontal displacements and relatively large horizontal displacements of the rails 12.

Further, between the connecting frame 15 and the thin cradle 24] the spring 3
0 is interposed, it is also possible to absorb the swinging displacement about the longitudinal axis of the rail 12.

In the above embodiment, two movable platforms 10.10 are installed on a -thread rail 12, but for example, a movable platform 10 may be individually installed on a plurality of rails 12 laid in parallel. It may be provided.

(Effects of the Invention) As described above in detail in the embodiments, in the moving platform according to the present invention, the load placed on the moving platform is distributed to the rail by the sliding face plate, so Excellent effects such as being able to easily slide large heavy objects even with a moving force can be obtained.
