Description

DETAILED DESCRIPTION OF THE INVENTION <<Industrial Application Field>> The present invention relates to the roof structure of a building, and more particularly to a movable roof moving mechanism for a retractable roof having a movable roof that can be partially opened and closed depending on the weather.

<<Prior Art and Problems>> As is well known, structures used for athletic events such as baseball stadiums and track and field stadiums do not have roofs attached to them. This is intended to allow athletic competitions to be held in as natural a environment as possible, but if it rains or it rains during a competition, the competition must be suspended or canceled.

Therefore, all-weather stadiums have recently been proposed, and for example, air membrane structures are attracting attention. However, the air membrane structure has the following problems.

In other words, an air membrane structure consists of a roof made of a membrane material made of synthetic resin, etc., and pressurized air that is slightly higher than atmospheric pressure is sealed inside. In order to prevent leakage to the outside, the entrance/exit structure becomes complicated.

Furthermore, not only does lighting and ventilation inside the stadium become difficult, but the purpose of the event is lost if the competition is held or watched in a natural environment.

Therefore, the applicant of this application has developed a retractable roof that can partially open and close the roof depending on the weather, allowing natural lighting and ventilation on sunny days, and allowing athletics to be held even on rainy days. -79099 (see Japanese Patent Application Laid-Open No. 62-236939)).

In this development, we not only opened and closed the roof, but also expanded the aperture ratio of the opening, and also reduced the weight of the movable roof and shortened the distance it moved, thereby reducing the load on the motor that powers it. In order to shorten the time it takes to open and close the roof, consideration has been given to ensuring a large opening while reducing the size of the movable roof. in particular,
For a fixed roof that is fixedly installed on a side wall erected on the ground and has an opening formed therein, a plurality of movable roofs are arranged on the fixed roof in multiple layers and mutually slidably movable, Each of these movable roofs is configured to slide toward the opening and cover the opening so that it can be opened and closed freely.With this configuration, the size of the opening can be secured large, and each movable roof can be slid toward the opening. The size of can be reduced.

By the way, in the above proposal, when moving the movable roof from the fixed roof into the opening, in order to guide and support the movement of the movable roof toward the opening, a guide is provided that extends and can be freely stored within the opening. A beam is installed. In particular, in the above proposal, this guide beam is arranged completely separately from the movable roof, and is configured so that it can be extended or retracted by rotating and moving within the opening. Instead of using such a large-scale method, other methods can also be considered in which the guide beams can be extended and retracted in a way that takes into consideration the moving operation of the movable roof. That is, it is conceivable that the movable roof be moved at the same time as the guide beam is extended and retracted. Furthermore, when providing a guide beam with a new configuration that also takes into account the movement of the moving roof, consideration must be given to how best to connect the moving roof onto the guide beam.

This invention was made in view of the above-mentioned conventional problems, and its purpose is to develop a new guide beam that can perform the extension and retraction operation of the guide beam together with the moving operation of the movable roof, and to develop a new guide beam suitable for this purpose.

The guide beam 5 is a hollow cylindrical body with a square cross section, and includes an outer beam material 5a having a large hollow cross section and a middle beam material 5 having successively smaller hollow cross sections.
(b) It consists of an inner beam material 5c, and the beam material with a smaller cross section is inserted into and removed from the hollow part of the beam material with a larger cross section, so that the whole structure is expandable and retractable.
The outer beam material 5a having the largest cross section is
The outer wall 1 is connected to the main pillar (not shown) and the upper end of the outer wall 1 to form an arch-shaped cantilever frame structure.
A pair of annular beams 7 are arranged inside and outside along the circumferential direction of the
are connected and supported in a state extending radially inward from the outer wall 1, and the fixed roof 3 is constructed on the outer beam members 5a of these guide beams 5 and the annular beam 7.

The middle beam material 5b and the inner beam material 5c include steel wires attached to a single power source such as a motor that is driven to rotate in forward and reverse directions by electricity, compressed air, etc.
A chain or the like is connected, and when the power source is started, the middle beam 5b and the inner beam 5c are synchronously moved forward and backward into and out of the outer beam 5a, and thereby the guide beam 5 can extend into the opening 20.

Of course, the middle beam members 5b and the inner beam members 5c may be provided with power sources separately and connected to wires, chains, etc., and the beam members 5b and 5c may be driven independently. On the other hand, each of the movable roofs 4a,
The wheels 17a, 17b provided on the wheel 4b are driven by an electric motor or the like, and the wheels 17a, 17b are
The guide beam 5 may be configured to extend and contract by each of the movable roofs 4a and 4b that are moved by the drive.

The middle beam material 5b of the guide beam 5 configured in this way
and the tip of the inner beam 5c (the side end of the opening 20)
Each has an upper and lower moving roof 4a, 4b.
The inner ends of the two are connected via a connecting device 6.

And the middle beam material 5b and the inner beam material 5c are the outer beam material 5a.

The details of the connecting device 6 are shown in FIG. 4, and the connecting device 6 has a frame 8 that allows
It is fixedly installed on each tip of the middle beam member 5b and the inner beam member 5c. The underframe 8 attached to each of the beams 5b and 5c includes a rectangular bottom plate portion 8a and a set of vertical wall portions that integrally project upward from a pair of opposing side edges of the bottom plate portion 8a. 8b, and a side plate 11 that is detachably attached to the other pair of side edges via bolts 11a and surrounds the bottom plate part 8a together with the pair of vertical wall parts 8b, and the bottom plate part 8a is a horizontal sliding surface. Further, each of the pair of vertical wall portions 8b has a guide recess 10 formed between the side plates 11 along the longitudinal direction of the vertical wall portion 8b at the corner with the bottom plate portion 8a. And the bottom plate part 8a of this underframe 8
is provided with a sliding plate 12 whose flanges formed at both end edges are engaged with guide recesses 10 of the vertical wall portion 8b and which slide on the sliding surface 9 while being guided by the guide recesses 10. Furthermore, within the underframe 8, a spring 13 is interposed between the sliding plate 12 and each side plate 11 along the sliding direction of the sliding plate 12.
It is configured to buffer and absorb the movement while allowing the sliding movement of 2. The vertical wall portions 8b of the underframe 8 are arranged in parallel in the direction of expansion and contraction of the guide beam 5, and the sliding plate 12 slides when it comes into contact with another adjacent movable roof 4, and buffers the impact. It is designed to have a function of preventing the guide beam 5 from being applied directly to the guide beam 5 side.

A rotating base 14 is fixed to the upper surface of this sliding plate 12. A column 15 is provided in the pivoting base 14 so as to be rotatably fitted thereinto. A swing base 16 is provided at the top of the support column 15 so as to be swingable around a horizontal axis using a pin support structure and coupled to each of the movable roofs 4a and 4b.

The coupling device 6 uses the sliding plate 12, the support column 15, and the swing base 16 to allow the slide plate 12 to horizontally slide the guide beam 5 in the axial direction, to horizontally pivot around the support post 15, and to the swing base. The platform 16 is allowed to swing in the vertical direction to allow various relative displacements between the guide beam 5 and the movable roof 4. Therefore, even if the guide beam 5 shakes, the movable roof 4 can be prevented from swinging.

Now, according to the above configuration, in rainy weather or in summer, the upper and lower movable roofs 4a and 4a of the movable roof 4,
4b is moved to the opening 20 and closed, and the movable roof 4 and fixed roof 3 form a dome-shaped roof, which can prevent rainwater from entering and block sunlight. When the weather is sunny or during the middle of the season, the movable roof 4 can be replaced with the fixed roof 3.
It moves upward and opens the opening 20, allowing athletics to take place under the sky.

Further, since the movement of the movable roof 4 utilizes the expansion and contraction motion of the guide beam 5, when the opening 20 is opened, the guide beam 5 is not present in the opening 20, giving a great sense of openness.

In particular, in this embodiment, a novel guide beam 5 can be obtained which allows the movable roof 4 to be moved by the extending and retracting operation of the guide beam 5 which is driven to expand and contract.

In addition, it is possible to buffer shocks caused by various relative movements between the movable roof 4 and the guide beam 5 and the contact between the movable roof 4 and other movable roofs 4 adjacent to each other, and this shock is directly applied to the guide beam 5 side. This can be prevented.

In the above embodiment, a circular sports stadium is illustrated, but other shapes, such as an ellipse or a polygon, can of course be applied.

Furthermore, the movable roof 4 is configured not only to be moved in the diametrical direction above the fixed roof 3 as in the above embodiment, but also to be moved below the fixed roof 3 or to be stored inside the fixed roof 3. You may.

<<Effects of the Invention>> As explained in detail in the embodiments above, according to the present invention, each guide beam 5 is inserted into and removed from the small diameter inner beam members 5b and 5c inside the large diameter outer beam member 5a. By making the whole part expandable and retractable, the opening 20

Since this is provided, it is possible to obtain a novel guide beam 5 in which the movable roof 4 can be moved by the extension and retraction operation of the guide beam 5 by the expansion and contraction drive.

Further, an underframe 8 attached to the guide beam 5 allows the coupling device 6 to be moved relative to the guide beam 5 and the movable roof 4 by horizontal sliding movement, horizontal rotation movement, and vertical swinging movement. , a sliding plate 12 slidably provided on the underframe 8, and a sliding plate 12
This structure is made up of a pivoting pedestal 14 provided on the pivot pedestal 14, a support 15 rotatably provided on the pivot pedestal 14, and a swinging base 16 that is swingably supported by the support 15 and coupled to the movable roof 4. , moving roof 4 and guide beam 5
It is possible to buffer shocks caused by various relative movements between the movable roofs 4 and the contact between the movable roof 4 and other movable roofs 4 adjacent to each other, and to prevent this shock from being applied directly to the guide beam 5 side.

Further, since the guide beam 5 and the movable roof 4 are not completely integrated, they can be handled separately by releasing the connection by the connecting device 6, which saves time and effort in constructing the guide beam 5. This has various effects such as making partial repairs and transportation easier.
