この発明は、電車、バスなどの車体に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to vehicle bodies such as trains and buses.
いま、電車の車体を例にとれば、車体は、屋根
板、両長ケタ、両軒ケタ、両側板、両長土台、両
側ハリ、床板および前後板が相互に溶接されると
ともに、屋根板および両側板などは、さらに複数
枚の小巾の金属板を溶接することにより所定の形
態につくられる。バスの車体についてもこれと
ほゞ同様のことがいえる。 Now, if we take a train car body as an example, the car body has a roof plate, both long girders, both eave girders, both side plates, both long bases, both side ribs, floor plates, and front and rear plates welded together, and the roof plates and The side plates and the like are further made into a predetermined shape by welding a plurality of narrow metal plates. The same thing can be said about the body of a bus.
従来の車体は、上記のように非常に溶接箇所が
多いので、その製造が非能率的であるし、多くの
熟練溶接工を必要とした。 Conventional car bodies have a large number of welded parts as mentioned above, making manufacturing inefficient and requiring many skilled welders.
この発明の目的は、上記の問題点を解決すると
同時に、従来の車体では考えられなかつた遮音断
熱空気層形成用中空部を備えた屋根を一体的に有
する車体を提供することにある。 An object of the present invention is to solve the above-mentioned problems and at the same time provide a vehicle body that integrally has a roof provided with a hollow portion for forming a sound-insulating air layer, which has not been considered in conventional vehicle bodies.
この発明による車体は、上述の目的を達成する
ために、屋根、両側壁および底壁を一体的に備え
た角筒状の金属押出型材製本体と、金属押出型材
製本体に、その前後の開口部を塞ぐように溶接せ
られた金属製前後壁とよりなり、屋根に遮音断熱
空気層形成用中空部が備わつているものである。 In order to achieve the above-mentioned object, the vehicle body according to the present invention includes a rectangular cylindrical main body made of extruded metal material integrally equipped with a roof, both side walls, and a bottom wall, and an opening in the front and rear of the main body made of extruded metal material. It consists of metal front and rear walls welded together to close the roof, and the roof is equipped with a hollow part for forming a sound-insulating air layer.
この発明による車体は、上述のような構成を有
するので、角筒状の金属押出型材製本体と、金属
製前壁と、金属製後壁との３部材を溶接するだけ
で組立てられる。したがつて、車体の溶接箇所は
僅か２箇所のみになり、車体の製造が能率化する
うえに、熟練溶接工の数も少なくてすむ。また屋

影響を効果的に阻止することができるし、屋根自
体の自重を少なくし、両側壁への負荷を少くする
こともできこの中空部は本体の押出成形時に同時
にうることができる利点もある。さらに本体が金
属押出型材製であることから、長さ方向にのびた
所望厚肉部分や横断面凹凸部分などを任意にうる
ことができる。 Since the vehicle body according to the present invention has the above-described configuration, it can be assembled by simply welding three members: a rectangular cylindrical main body made of extruded metal material, a metal front wall, and a metal rear wall. Therefore, there are only two welding points on the vehicle body, which not only streamlines the manufacturing of the vehicle body, but also reduces the number of skilled welders. In addition, the roof itself has many hollow sections extending in the length direction that form sound-insulating air layers in parallel, effectively blocking noise from the roof side and the influence of outside temperature from entering the vehicle body. Moreover, the weight of the roof itself can be reduced, and the load on both side walls can be reduced.This hollow part also has the advantage of being formed at the same time as the main body is extruded. Further, since the main body is made of an extruded metal material, a desired thick portion extending in the length direction and an uneven portion in cross section can be formed as desired.

る。 The drawing shows the body of a train, which includes a main body 5 made of extruded aluminum in the shape of a rectangular tube integrally equipped with a roof 1, side walls 2, 3, and a bottom wall 4;
It consists of a main body 5 made of extruded aluminum material and front and rear walls 6, 7 made of aluminum plates welded so as to close the front and rear openings of the main body 5. A required number of sound-insulating, heat-insulating air layer hollow portions 8 are formed in parallel.

は、必要な補強などが施される。 The side walls 2 and 3 have downwardly extending portions 2a and 3a that extend downward by the portion where the conventional side stiffness exists.
is provided. The door-equivalent portion 9 and the window-equivalent portion 10 are punched out from both side walls 2 and 3 after the main body 5 is extruded. Further, the main body 5 and the front and rear walls 6, 7 are provided with necessary reinforcement.
本体５および前後板６，７にはアルミニウムが

トレーラなどの車体も基本的にこれと同様の構成
がとられる。 Although aluminum is used for the main body 5 and the front and rear plates 6, 7, steel and other metals can also be used. The one shown is the body of a train, but the body of a bus,
Vehicle bodies such as trailers basically have a similar configuration.
