Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a movable roof in an existing outdoor facility such as a baseball field stadium without interrupting utilization of the facility.

[0002]

[Prior Art] Existing baseball fields, soccer stadiums,
In other stadium facilities, for example, apart from things like Korakuen Stadium and Fukuoka Dome Stadium, it is generally an outdoor facility. It is easily affected.

Therefore, it has been proposed to renew such an existing outdoor stadium facility as a large-scale structure having a retractable roof structure. The open / close type is used because a feeling of opening, which is an advantage unique to conventional outdoor facilities, can be obtained when the roof is opened.

However, in constructing a roof on this existing facility, the following various problems occur.

[0005]

First of all, the portion to which the roof is hung and the facility around the roof are construction areas, and the facilities cannot be used during the construction period. In addition, temporary construction will be quite large because an extremely large roof is hung on a vast area.

Further, in order to make the roof movable, the construction period is extended due to the complexity of construction, the influence on the use of the facility is increased, and the use of the facility becomes impossible for a certain period of time.
The construction work itself, which causes this, becomes a negative factor.

[0007] For example, in professional baseball, 4
The pennant race will be held from October to October, and the off-season will be from 11 to March, so it would be good if the facility use was temporarily suspended during this off-season (about 5 months), and rapid construction could be done during that period. It is not realistic because it hangs a very large roof like.

The present invention has been made in view of the above problems, and an object thereof is to make it possible to carry out roofing work all year long while sufficiently ensuring safety and comfort for users. A method for constructing a moving roof for an outdoor facility is provided.

[0009]

In order to achieve the above object, the invention according to claim 1 of the present invention is supported outside an existing outdoor facility and covers the upper portions of the left and right wings of the outdoor facility. The first step of erection of a pair of fixed roofs, the fixed roof is used as a gantry, and one or a plurality of movable roof steel frames are sequentially assembled on the upper part of the fixed roof, and both ends of the movable roof are installed outside the existing outdoor facility. And a third step of laying a roof membrane while deploying the movable roof steel frame along the guide rail.

Therefore, according to the present invention, once the fixed roof is completed, the movable roof construction can be sequentially performed on the upper portion of the fixed roof as a gantry, so that the facility is not occupied by temporary construction and the like The construction work can be continued while ensuring sufficient safety.

According to a second aspect of the present invention, the first and third steps are performed during the non-use season of the outdoor facility, and the second step is continuously used during the non-use season. By performing it during the season, each process can be linked to the usage period and non-use period of the facility.

According to the third aspect of the present invention, since the existing outdoor facility is a baseball field, for example, a process procedure adapted to a pennant race such as professional baseball and off season can be provided.

[0013]

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

1 and 2 show the concept of the method of the present invention. In the figure, the existing baseball stadium 1 subject to renovation work has a gate 2 in the center of the outfield, and passengers who pass through the gate 2 as indicated by the arrow in the figure are designated while walking on a smooth continuous slope from the outfield seat side. It is a building that can be moved to the designated seats.

The left and right wings of the baseball field 1 are continuous to the outfield side and the infield side respectively, and a pair of leg portions 3 at both ends thereof.
, A pair of fixed roofs 4 fixedly installed on the outer side of the baseball field 1, and a middle movable roof 5 and an upper movable roof 6 having substantially the same area as the fixed roofs 4 are stacked on each fixed roof 4. It

A pair of legs 7 and 8 on both sides of each movable roof 5 and 6 are provided with guide rails 9 provided on a ground surface portion outside the baseball field 1 and a support frame 11 arranged outside the infield side. By moving the movable roofs 5 and 6 from the state shown in FIG. 1 along the guide rails 9 and 10 toward the center of the baseball stadium 1 and aligning them at the center, , The baseball field 1 as shown by the broken line in FIG.
Can cover the entire top of the.

In the fully open state, the upper parts of the left and right wings of the baseball field 1 are basically covered by the area of the fixed roof 4, but basically, the outdoor facility has a feeling of openness. Even in the fully closed state, as shown by the arrow, the left and right wings can fully see the outside scenery and nature. Further, the legs of the roofs 4, 5, and 6 are sufficiently high so that even if the entire baseball field 1 is covered, the surrounding visibility can be sufficiently secured.

FIG. 3 is a process explanatory view showing an example of the construction procedure of the present invention, and construction is carried out sequentially from the left side in the figure.

This construction schedule is linked to the professional baseball schedule. For example, assuming that the construction will start in 1996, the base construction will be carried out during the latter half of September and October during the opening of the pennant race. Construction, construction of various materials and equipment, etc., and construction permit approval will be made to the extent that they will not affect the facilities at Site 1.

Next, during the five months from November 1996 to March 1997, which is the first off-season period, the steel roof erection work for the fixed roof 4 and the movable rail skeleton work are performed.

First, in parallel with the skeleton construction that constitutes the support portion of the fixed roof 4, a temporary gantry for the fixed roof construction is assembled, and when this is completed, the steel erection work for the fixed roof 4 is performed, and , As the construction progresses, fall prevention curing is done.

After the steel frame construction is completed, the temporary gantry is removed, and the middle stage support for drop curing is set. Further, in the ground surface portion, support ground construction for the movable rail portion (outfield side) and construction of the support frame 11 (infield side) are performed in the next process.

After the completion of this first construction, the pennant race was resumed from April 1997, and users could safely watch the game under the fixed roofs 4 located on both left and right wings, and as a franchise baseball stadium. Can be used.

During this pennant race period, movable roof steel frame erection work and movable rail and trolley installation work are carried out.

First, on the steel frame which constitutes the fixed roof 4, a steel frame erection which constitutes the movable roofs 5 and 6 is performed by using this as a gantry. In parallel with this, the rail support frame 1 in the infield and outfield
Rail installation work will be performed on 1 and the ground. Each time a movable roof steel frame is completed, a trolley is set on each rail and support reshuffles are performed. Of course, this construction schedule is carried out according to the game schedule, and the construction can be progressed by choosing the day and time when there is no game. At the beginning of November when the pennant race is almost complete, the movable roof 5 The steel frames forming the frames 6 and 6 are moved from the stacked state.

The second season off after the end of the pennant race is November, and in March of the following year, a roof membrane is first laid on the upper part of the upper movable roof steel frame, and when the upper movable roof 6 is completed, it is moved. Then, when the middle stage movable roof 5 is completed by exposing the surface of the middle stage movable roof steel frame and stretching the roof membrane,
This is moved to expose the surface of the fixed roof steel frame, and a roof membrane is stretched to complete the fixed roof 4. After that, system adjustment and confirmation for finishing work and roof drive will be performed, and completion and delivery will be performed. Therefore, when the Pennant Race is held in April, you can enjoy the opening game with the newly refurbished dome roof stadium.

FIGS. 4, 5 and 6 show the morphological change of the stadium after completion.
As shown in Figure 4, by leaving the movable roofs 5 and 6 on the fixed roof 4, the vertical and horizontal front and rear surfaces of the baseball field are fully opened, and you can enjoy the scenery open to the outdoors while enjoying the game contents. You can also

In the case of a rainy game or rain during the game, the movable roofs 5 and 6 are sequentially turned as shown in FIG. 5, and the movable roofs 6 are placed on the upper center line of the baseball field 1. The entire baseball field 1 can be covered by matching with.

During the turning of the movable roofs 5 and 6, it is necessary to prevent an accidental contact with the visitors due to the turning motion at the location where the rails for moving the movable roof located on the surface of the outfield are placed. There is. Therefore, in the present invention, as shown in FIG. 7, the rail 9 is arranged above the underground continuous wall 20 pre-installed in the ground E and in the underground, and the legs 7 and 8 are movable. While supporting and fixing, the leg portion 7 is supported by the pair of bridges 21 arranged on the ground surface portion.
A method is adopted in which the periphery of 8 is allowed to pass and the bridge 21 is flipped up during a moving operation.
The flipped-up bridge 21 can sufficiently secure safety as a closed road for people who enter and leave the baseball field 1.

It is needless to say that the present invention can be applied not only to existing baseball fields, but also to soccer fields, athletic fields, and other existing outdoor facilities used for sports competitions in general.

[0031]

As is apparent from the above description, in the method of constructing the movable roof for the existing outdoor facility according to the present invention, once the fixed roof is completed, this is used as a gantry and is sequentially placed on top of it. Because movable roof construction can be implemented,
The facility will not be occupied by temporary work, and the work can be continued while ensuring sufficient safety for users.
