Japanese Examined Patent Publication No. 6-63386

  In a building structure such as a stadium or a stadium, an event with a high attendance rate so that the spectator seats are full is not always held. If an event is held with the same ceiling height as an event with a high rate of attracting customers, when the event cannot be expected to have a high rate of attracting customers and there are few spectators, air conditioning will be applied to a wasteful space compared to the rate of attracting customers. Because it will perform ventilation and ventilation, usage efficiency such as utility costs will deteriorate.

  In the building structure 100 described in Patent Document 1 as described above with reference to FIG. 4, the membrane structure roof 101 only moves up and down depending on the weather, and the membrane structure roof depends on the rate of attracting customers. There is no study on raising and lowering 101. That is, as shown in FIG. 4 (a), it is possible to hold an event in which the audience seats are full in a state where the membrane structure roof 101 is fully lowered and the volume is minimized, and the rate of attracting visitors When is low, it is impossible to make the air volume further smaller than the state of FIG.

  Problem to be solved by the invention is providing the building structure provided with the roof which can be raised / lowered which can reduce a maintenance cost.

The present invention employs the following means in order to solve the above problems. That is, a building structure having a roof that can be raised and lowered according to the present invention includes a stepped floor portion inclined in a downward direction toward the front, a spectator seat provided on the stepped floor portion, and a roof that can be raised and lowered. When the roof is lowered, the lower surface of the lowered roof approaches a part of the spectator seat, and a part of the spectator seat is covered by the lower surface of the roof.
According to such a configuration, the building structure has a roof that can be raised and lowered, and when the roof is lowered, the lower surface of the lowered roof approaches a part of the audience seat, and a part of the audience seat is a roof. Since it is covered by the lower surface, the space above a part of this spectator seat is closed by the roof. As a result, during events with a low rate of attracting customers, the roof is lowered, and the lowered roof is positioned above some spectator seats to make it unusable, reducing the volume and increasing the rate of attracting customers. In such a case, it is possible to operate such that the roof is raised and all spectator seats can be used. That is, it is possible to change the volume according to the customer collection rate. Thereby, it becomes possible to reduce the maintenance cost of building structures, such as the utility cost required for air conditioning.
In addition, the number of spectator seats that can be used with the roof lowered is the number of spectators that can be used with the roof raised, and the number of spectators that can be used with daily roofing is not so high. The number can be the number of customers expected at large events such as world-class competitions where the frequency of holding is low and the rate of attracting customers is high. In such a case, it is possible to operate the building structure by lowering the roof at normal times, and to raise the roof only at a large event with a low frequency. Thereby, the height in normal time can be reduced as much as possible, and a building structure considering the landscape can be realized.
In addition, the normal roof requires a certain thickness, but for the part of the roof that is covered by the roof when the roof descends and corresponds to some spectator seats, the direction in which the roof descends forward rather than upward It is possible to increase the thickness downward along the stepped floor portion. Thereby, it becomes possible to make the height of the upper surface of a roof low, and it can implement | achieve the building structure which considered the scenery effectively.

In one aspect of the present invention, a part of the spectator seat is provided on the stepped floor portion on the outer peripheral side of the building structure, and the roof is the stepped floor portion provided with a part of the spectator seat. The lower surface on the outer peripheral side is formed to be inclined so as to correspond to the inclination.
According to such a configuration, since the lower surface of the roof is formed so as to correspond to the inclination of the stepped floor portion, the distance between the spectator seat and the lower surface of the roof when the roof is lowered can be reduced. Is possible. Therefore, it is possible to reduce the maintenance cost of the building structure such as the utility cost as described above, and to achieve the effect that the building structure considering the landscape can be realized more efficiently. Is possible.

In one aspect of the present invention, the roof has a truss structure.
According to such a configuration, it is possible to easily realize a roof structure that is thick in the downward direction along the stepped floor portion that is inclined in the downward direction toward the front.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the building structure provided with the roof which can raise / lower which can reduce a maintenance cost.

In the present embodiment, the competition execution unit 2 has a rectangular shape in plan view. The competition execution unit 2 may be, for example, a pool or a ground.

  The building structure 1 is provided with a stepped floor portion 3 provided in a step shape that is inclined in a forward direction, that is, in a direction descending in the direction of the competition execution portion 2 or the like, on the outside of the competition execution portion 2. Hereinafter, in the side view shown in FIG. 1 and the like, the direction on the competition execution unit 2 side is appropriately referred to as “front” and the opposite side is referred to as “rear” with respect to the stepped floor portion 3. The step floor portion 3 includes a front step floor portion 3A provided at a front position close to the competition execution portion 2, and a rear step floor portion 3B provided behind the front step floor portion 3A. On the step floor 3 (3A, 3B), a spectator seat 6 is provided as shown in FIG.

  As described above, since the competition execution unit 2 has a rectangular shape, the stepped floor portion 3 is provided along each side of the competition execution unit 2. That is, although not shown in FIG. 1, the stepped floor portions 3 are also installed at both ends in the paper depth direction in FIG. 1, whereby the competition performing portion 2 is surrounded by the stepped floor portion 3.

  The building structure 1 includes a roof 5. The roof 5 has a truss structure and is supported by support pillars 4 provided near or in the step floor 3. The lower surface 5a of the roof 5 includes a lower end surface 5b and an inclined surface 5c. The lower end surface 5b is the lower surface 5a of the roof located above the competition execution unit 2 and the front step floor 3A, and is a horizontal plane formed parallel to the ground. The inclined surface 5c is a lower surface located on the outer peripheral side of the roof 5 so as to surround the periphery of the lower end surface 5b, and is located above the rear stepped floor portion 3B. The inclined surface 5c is formed to gradually incline upward from the outer periphery of the lower end surface 5b toward the outside at an angle substantially equal to the inclination angle of the rear step floor 3B. Thereby, the roof 5 is a lower surface on the outer peripheral side so as to correspond to the inclination of the outer peripheral side stepped floor portion 3 of the building structure 1 provided with a part of the spectator seat 6, that is, the rear stepped floor portion 3B. The inclined surface 5c is formed to be inclined.

  As shown in FIG. 2, the support column 4 includes a support body 4 a having a lower end fixed in the vicinity of the stepped floor portion 3 or in the stepped floor portion 3, and a column 4 b. The support 4a has a larger cross-sectional shape than the support 4b, and the lower end of the support 4b is inserted into the support 4a through an opening (not shown) provided on the upper surface of the support 4a. The lower end of the column 4b is connected to the support 4a through a lifting device such as a hydraulic jack (not shown) inside the support 4a. The upper end of the column 4 b is joined to the lower surface 5 a of the roof 5. By operating the lifting device, the support column 4 b is lifted and lowered, so that the roof 5 can be lifted and lowered with respect to the stepped floor portion 3.

  The state in which the roof 5 is lowered is shown in FIG. 1 (a), FIG. 2 (a), and FIG. The roof 5 is lowered by the elevating device in the support column 4 when the column 4b is lowered in the support 4a. In this state, as a result of the roof 5 being lowered, the inclined surface 5c of the roof 5 is located immediately above the rear stepped floor portion 3B and the spectator seat 6 provided thereon. As described above, since the rear stepped floor portion 3B and the inclined surface 5c of the roof 5 have substantially the same inclination angle, the inclined surface 5c of the roof 5 includes the rear stepped floor portion 3B and the spectator seat 6 above it. It is located directly above these along the slope of. Thereby, the inclined surface 5c of the lower surface 5a of the lowered roof 5 is close to a part of the spectator seat 6, that is, the spectator seat 6 located on the rear stepped floor portion 3B, and a part of the spectator seat 6 is a roof. 5 is covered with a lower surface 5a.

  In the front of the rear stepped floor portion 3B, a closing membrane 7 at the time of lowering is provided between the upper surface of the stepped floor portion 3 and the lower surface 5a of the lowered roof 5 so as to block the rear stepped floor portion 3B and the competition implementation portion 2. Is provided. The descending closing membrane 7 is formed of a membrane material such as cloth or artificial fiber. When the roof 5 is raised, the closing membrane 7 is wound around a roller pipe (not shown) installed on the lower surface 5a of the roof 5, and when the roof 5 is lowered, the closing membrane 7 is pulled out from the roller pipe, It is installed by fixing the tip of the closing membrane 7 at the time of descending to the upper surface of the rear stepped floor 3B. The upper surface of the competition execution unit 2 and the front step floor 3A, the lower end surface 5b of the roof 5, and the closing closure membrane 7 form a roof lowering space S1 that encloses the competition execution unit 2 and the front step floor 3A. Yes.

  As particularly shown in FIGS. 2 and 3, the roof is formed to protrude further outward than the outer peripheral end surface 3 a of the rear stepped floor portion 3 </ b> B. The outermost peripheral end of the lower surface 5a of the roof 5 that protrudes outward from the outer peripheral end surface 3a of the rear stepped floor 3B is a protruding portion 5d that protrudes downward, and when the roof 5 is lowered, this protruding portion 5d. Thus, the space S3 between the rear step floor 3B and the inclined surface 5c of the roof 5 shown in FIG. 3 is closed from the outside of the outer peripheral end surface 3a of the rear step floor 3B.

  The state in which the roof 5 is raised is shown in FIGS. 1 (b) and 2 (b). The roof 5 is raised by the elevating device in the support column 4 when the column 4b is raised in the support 4a. In this state, as a result of the roof 5 rising, a space S <b> 4 is formed between the rear stepped floor 3 </ b> B and the spectator seat 6 provided thereon and the inclined surface 5 c of the roof 5.

  At the rear of the rear stepped floor portion 3B, a rising-time closing membrane 8 is provided between the upper surface of the rear stepped floor portion 3B and the inclined surface 5c of the raised roof 5 so as to shield the rear stepped floor portion 3B from the outside. Is provided. The rising closing membrane 8 is formed of a membrane material such as cloth or artificial fiber, like the falling closing membrane 7. The ascending closing membrane 8 is wound around a roller pipe (not shown) installed on the inclined surface 5c of the roof 5 when the roof 5 is lowered, and the ascending closing membrane 8 is drawn from the roller pipe when the roof 5 is raised. It is installed by fixing the tip of the closing membrane 8 when lifted to the upper surface of the rear stepped floor 3B. The competition execution section 2, the front step floor section 3A and the rear step floor section 3B, the lower end surface 5b and the inclined surface 5c of the roof 5, and the closing closing membrane 8 on the upper side of the competition execution section 2, the front step floor section 3A and the rear A roof rising time space S2 including the stepped floor portion 3B is formed.

  Next, the usage method of the roof 5 is demonstrated.

  In the case of holding a normal event where a high rate of attracting customers cannot be expected and there are few spectators, the roof 5 is operated in a lowered state as shown in FIG.

  When holding an event with a high attendance rate so that the audience seats are full, the roof 5 is moved from the lowered state to the raised state shown in FIG. First, the closing membrane 7 during lowering is wound around a roller pipe installed on the lower surface 5 a of the roof 5 and removed. Next, the elevating device of the support column 4 is operated to raise the column 4b, thereby raising the roof. Finally, the ascending closing membrane 8 is drawn out from the roller pipe installed on the inclined surface 5c of the roof 5, and the tip thereof is fixed to the upper surface of the rear step floor 3B.

  When an event with a low customer acquisition rate is to be held after an event with a high customer acquisition rate, the roof 5 is moved from the raised state to the lowered state by the following procedure. First, the closing closing membrane 8 is wound around a roller pipe installed on the inclined surface 5c of the roof 5 and removed. Next, the elevating device of the support column 4 is operated to lower the column 4b to lower the roof. Finally, the closing membrane 7 is pulled out from the roller pipe installed on the lower surface 5 a of the roof 5, and its tip is fixed to the upper surface of the stepped floor portion 3.

  Next, the action and effect of the building structure 1 including the roof 5 that can be moved up and down shown as the first embodiment will be described.

  The building structure 1 as described above includes the roof 5 that can be raised and lowered, and when the roof 5 is lowered, the lower surface 5a of the lowered roof 5, in particular, the inclined surface 5c is a part of the audience seat 6, that is, the rear stage. Since a part of the audience seat 6 is covered with the inclined surface 5c of the roof 5 close to the audience seat 6 located on the floor 3B, the space above the part of the audience seat 6 is closed by the roof 5. . As a result, in the event of a low attendance rate, the roof 5 is lowered, and the lowered roof 5 is positioned above some spectator seats 6 to make it unusable. In the event of a high event, the roof 5 is raised so that all the spectator seats 6 including the spectator seats 6 on the rear step floor 3B can be used. That is, it is possible to change the volume according to the customer collection rate. Thereby, it becomes possible to reduce the maintenance cost of the building structure 1, such as the utility cost required for air conditioning.

  In addition, the number of spectator seats 6 that can be used with the roof 5 lowered is set to the number of spectators that can be used in daily events that do not have a high rate of attracting customers, and can be used with the roof 5 raised. The number of spectator seats 6 can be set to the number of people expected in large events such as world-class competitions with a low frequency of holding and a high rate of attracting customers. In such a case, it is possible to operate the building structure 1 by lowering the roof 5 at normal times, and to raise the roof 5 only at a large event with a low frequency. Thereby, the height in normal time can be reduced as much as possible, and the building structure 1 in consideration of the landscape can be realized.

  Further, the normal roof 5 requires a certain thickness, but the roof 5 is covered with the roof 5 when the roof 5 is lowered, that is, the roof 5 corresponding to the spectator seat 6 located on the rear stage floor portion 3B. In the vicinity of the inclined surface 5c, which is a portion of the above, it is possible to increase the thickness of the roof 5 in the downward direction along the stepped floor portion 3 that inclines in the downward direction toward the front rather than in the upward direction. Thereby, it becomes possible to make the height of the upper surface of the roof 5 low, and the building structure 1 in consideration of the landscape can be effectively realized.

  Further, since the inclined surface 5c of the roof 5 is formed to be inclined so as to correspond to the inclination of the rear stepped floor portion 3B, the audience seat 6 when the roof 5 is lowered and the lower surface 5a of the roof 5, that is, the inclined surface 5c. It is possible to reduce the distance between Therefore, it is possible to reduce the maintenance cost of the building structure 1 such as the utility cost, and to achieve the above effect that the building structure 1 in consideration of the landscape can be realized. Can be played.

  Further, since the roof 5 has a truss structure, it is possible to easily realize the structure of the roof 5 that is thickened downward along the rear stepped floor portion 3B that is inclined downward. It becomes possible.

  In addition, the building structure provided with the roof which can be moved up and down according to the present invention is not limited to the above-described embodiment described with reference to the drawings, and various other modifications can be considered within the technical scope thereof. .

  For example, the building structure may be specialized for other specific competitions such as a baseball stadium and a skate rink, or may be used for other purposes.

Moreover, in the said embodiment, although the competition implementation part was rectangular shape, you may provide other shapes, such as circular and an ellipse.
In addition, in the above embodiment, the step floor portion is formed in a straight line in the direction along the end side because the end portion of the competition execution portion is linear, and therefore the audience seat is also in the horizontal direction. Although it is arranged in a straight line, if the competition implementation part is circular or elliptical and the edge of the competition implementation part is curved, the corrugated floor part is also formed in a curved shape corresponding to this, The spectator seats may be arranged in a curved line in the lateral direction so as to surround the competition execution section.
In addition, as long as the roof has a shape corresponding to the inclined shape of the rear stepped floor, the outer shape in plan view does not depend on the outer periphery of the competition execution portion or the stepped floor, and any shape It does not matter.

  Moreover, in the said embodiment, although the hydraulic jack was used as a raising / lowering apparatus, another apparatus may be sufficient.

  Further, in the above embodiment, a membrane material such as a closing membrane when descending, a closing membrane when rising is used as a member that shields the front and rear stepped floor portions or the rear stepped floor portion and the outside. Instead of this, a plate material may be used. In addition, when installing and removing the closing membrane, the closing membrane, etc. when descending, these membrane materials were pulled out from the roller pipe and wound, but this is not a limitation, and membrane materials cut into an appropriate shape are appropriately used. They may be transported from other locations.

  In addition to this, the configuration described in the above embodiment can be selected or changed to another configuration as appropriate without departing from the gist of the present invention.
