この発明は、競技場、演技基等の大屋根を開閉できるよ
うにした開閉式屋根における鉄骨トラスの支承装置に関
するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a support device for a steel truss in a retractable roof of a stadium, performance stadium, etc., which can be opened and closed.
従来、長大スパンの鉄骨骨組の開閉式大屋根のトラスは

用の車輪等の移動機構が取付けられた構造のものが知ら
れている。Conventionally, in the case of a large retractable roof truss with a long span steel frame, one end of the truss 21 has a fixed support 22, as shown in FIG.
The other end is a movable support 23 to prevent distortion due to expansion and contraction of the length of the truss caused by its own weight and temperature changes, and in addition, the lower part of these supports 22 and 23 is used to open and close the roof. A structure in which a moving mechanism such as wheels for moving is attached along a rail 24 is known.

重、雪荷重または温度変化等によって生じるトラスの長

が、地震の場合、他端は可動支承となっているため地震
による水平力を伝達せず一端の固定支承のみで地震力を
負担しなければならずトラスの両端で均等に地震力を負
担して処理することができず耐震安全性が低くなるとい
う問題点があった。In the conventional steel truss structure, expansion and contraction in the longitudinal direction of the truss caused by the truss's own weight, suspension load, snow load, temperature change, etc., does not affect the lower structure because the other end is a movable support. However, in the case of an earthquake, since the other end is a movable support, the horizontal force due to the earthquake is not transmitted, and the earthquake force must be borne only by the fixed support at one end, so it is distributed equally at both ends of the truss. There was a problem in that the seismic safety was lowered because it was unable to bear and handle the seismic force.
この問題をなくすためにトラスの両端を共に固定支承と
した場合、地震力は両端で半分ずつとなってバランスよ
く負担するので耐震安全性は高くなるが、自重、つり荷
重、雪荷重または温度変化等によるトラスの長手方向の
変位を逃すことができずトラスにひずみを生じ移動機構
に無理な力が加わり車輪とレールとが円滑にかみ合わず
走行できなくなる場合を生ずる問題点があった。In order to eliminate this problem, if both ends of the truss are fixedly supported, the seismic force will be borne in half at both ends and will be borne in a well-balanced manner, increasing seismic safety. There is a problem in that the displacement of the truss in the longitudinal direction due to such factors cannot be relieved, causing distortion in the truss and applying unreasonable force to the moving mechanism, resulting in the wheels and rails not meshing smoothly and making it impossible to run.
この発明は、鉄骨トラスの長手方向の変位を逃がしてト
ラスのひずみを生じることがないようにするとともに、
地震力はトラスの両端に均等に負担させて耐震安全性を
高めた開閉式屋根の鉄骨トラスの支承装置を得ることを
課題とするものである。This invention prevents distortion of the truss by escaping displacement in the longitudinal direction of a steel truss, and
The objective is to obtain a support device for a steel truss with a retractable roof that increases seismic safety by applying the seismic force evenly to both ends of the truss.
前記の課題を解決するためこの発明は、鉄骨トラス１の
一端を固定支承２を介して、また他端を鉄骨トラス１の
移動方向Ａと直交する長手方向の変位を許す可動支承４

承４として速度比例型粘性ダンパーを用いた開閉式屋根
における鉄骨トラスの支承装置の手段を講じるものであ
る。In order to solve the above problems, the present invention provides a movable support 4 that allows one end of a steel truss 1 to be displaced via a fixed support 2 and the other end of the steel truss 1 in a longitudinal direction perpendicular to the moving direction A.
The present invention is mounted on the moving mechanism 3 via the movable support 4, and uses a speed-proportional viscous damper as the movable support 4 to provide a support device for a steel truss in a retractable roof.
この発明の作用を実施例を参照して説明する。 The operation of this invention will be explained with reference to Examples.
鉄骨トラス１はその一端を固定支承２によって固定され
ているので、自重、吊り荷重、雪荷重または温度変化等
による長時間をかけて生ずる長さ方向の長さの変化は他
端の変位として表われるが他端には可動支承４として速
度比例型粘性ダンパーが使用されているので長時間をか
けた緩速度での変位では粘性体１９の粘性せん断力の値
は著しく小さいため鉄骨トラス１の移動機構には何等の
影響を与えないように自由に移動することができる。Since one end of the steel truss 1 is fixed by a fixed support 2, changes in length in the longitudinal direction that occur over a long period of time due to its own weight, suspension load, snow load, temperature change, etc. are expressed as displacement at the other end. However, since a speed-proportional viscous damper is used as the movable support 4 at the other end, the value of the viscous shear force of the viscous body 19 is extremely small during displacement at a slow speed over a long period of time, so the movement of the steel truss 1 is prevented. It can be moved freely without affecting the mechanism in any way.
しかし、地震時においては地震振動がきわめて短時間で
高速であるので他端の可動支承４として速度比例型粘性
ダンパーにおける粘性体１９の粘性せん断力の値は著し
く大きくなるため鉄骨トラス１の他端における長手方向
の変位を許されない。However, during an earthquake, the seismic vibration is extremely short and high-speed, so the value of the viscous shear force of the viscous body 19 in the velocity proportional viscous damper as the movable support 4 at the other end becomes extremely large. No longitudinal displacement is allowed.
そのため両端が固定支承と同様に働き地震力は鉄骨トラ
ス１の両端で均等に１／２ずつ負担され耐震安全性を高
めることができる。Therefore, both ends act like fixed bearings, and the seismic force is borne equally by 1/2 at both ends of the steel truss 1, improving seismic safety.

It is structured like this. Further, the base portion 1b at the right end of the steel truss 1 is attached to the shaft 5 via the movable support 4, and engages with the pinion 12 in the same way as the right end.

The support plate 13 that supports the base 1b has a protrusion 14 that engages with the base 1b on the upper part of the support plate 13, and a base plate 16 of the casing 15 fixed to the rack 5 is provided on the lower side of the protrusion 14. 13 is attached as a cover body thereof, and extends downwardly from both sides of the support plate 13, and has a space between it and the base plate 16 of the casing 15. A large number of thin plates 18 are mounted between the arms 17 with a space between them. The casing 15 is filled with a butane-based polymer compound 19 as a viscous material, allowing displacement when the displacement speed of the steel truss 1 is low, and inhibiting the displacement when the displacement speed is high. This constitutes a velocity proportional viscous damper with a function that does not allow this.

The thin plates 18a may be stacked and fixed in multiple stages so as not to contact the thin plates 18a.
