本発明は、例えば体育館等大空間の鉄骨造屋根
を架構するのに適用される鉄骨トラス・トラベリ
ング工法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steel truss traveling construction method that is applied to constructing a steel roof of a large space such as a gymnasium.
従来、上述鉄骨造屋根を架構する為の工法とし
ては、大型クレーンを建物内部に入場させ、屋根
下全面に大掛りな仮設支保工と、作業足場を組立

め鉄骨を地組し、これを吊り上げ、又は押し上げ
て架構するところのリフトアツプ・ブツシユアツ
プ工法が知られている。 Conventionally, the construction method for constructing the above-mentioned steel roof is to bring a large crane into the building, erect large-scale temporary support and work scaffolding under the roof, and then assemble the steel frame on the work scaffold. The lift-up and push-up construction methods are known, in which steel frames are assembled in advance on the ground and then hoisted or pushed up to construct the frame.
しかし、前者によると、クレーン及び足場除去
后はコンクリート打ちが不可欠となるからアリー
ナ床にダメ工事ができると共に、大空間を足場組
みすることは経費が膨大となるだけではなく、そ
の組立、解体に要する労力、時間も膨大なものと
なり、為に、工期が著しく長びき、かつ、コスト
高となる欠点がある。 However, according to the former, concrete pouring is essential after the crane and scaffolding is removed, which can damage the arena floor, and erecting scaffolding in a large space not only incurs enormous costs, but also involves the assembly and dismantling of the scaffolding. The amount of labor and time required is enormous, resulting in an extremely long construction period and high costs.
又、後者によると、トラスが非立体である場
合、又体育館のようにギヤラリーが迫り出した建
物である場合、更に躯体が鉄骨の柱ではなくRC
柱である場合では、アリーナ床上での鉄骨地組が
困難であり、又、鉄骨支持の反力点を確保し難い
点で、当該工法は採用し得ない場合もある。 Also, according to the latter, if the truss is not three-dimensional, or if it is a building with a protruding gear rally like a gymnasium, the frame is not made of steel columns but RC.
In the case of columns, it is difficult to assemble the steel frame on the arena floor, and it is also difficult to secure a reaction force point for supporting the steel frame, so this construction method may not be possible.
又、従来上述工法の難点に鑑みてなされたもの

ベリング工法は本願人において開発され、すでに
特許出願されている。 In addition, this was done in view of the drawbacks of the conventional construction methods mentioned above.In most cases, such as gymnasiums with large steel roofs, the grounds around the building can be fully utilized; The belt conveyor assembly process for assembly and delivery is highly accurate and safe, the construction can be completed with only slight changes to the original design of the steel truss, and temporary construction costs are low. From this perspective, the applicant has developed a steel truss traveling construction method that can take advantage of these uses, and a patent application has already been filed.

比較して仮設足場の縮少、工費の節減、定位置同
一作業の繰返しによる安全性及び施工精度の向
上、工期短縮等を計り得る点で十分に効果的であ
るといえる。 In other words, this method involves setting one side of a large space within the capacity of a crane from outside the building as a steel frame assembly zone, assembling one unit of the roof steel frame truss, and attaching a center hole type jack and roller for traction to this unit. , put it on the rail installed in advance on the beam in the direction of the girder and slide it by one unit width, then assemble the next unit in the empty steel frame assembly zone and add it to the above unit, slide it in order,
Since a large space steel roof is constructed by assembling and adding units, compared to the conventional construction method mentioned above, it reduces the need for temporary scaffolding, reduces construction costs, and improves safety and construction accuracy by repeating work in the same position. It can be said that it is sufficiently effective in terms of improvement and shortening of construction period.

の定着作業が煩雑となる問題点がある。 However, even in such a construction method, since a climbing jack is used as a device for moving the unit, there are problems with the fixing method, the erection of the rod, and the cost of reinforcing the reaction force. Attach the “locomotive style” on the rails.
In order to move the units, it is necessary to jack up all the units at the same time after towing, remove the rails and wheels, and then lower and fix them, which poses the problem of complicating the work of fixing the units.

得ることを目的とするものである。 Therefore, as a result of studies in view of the above-mentioned problems with the steel truss traveling construction method, the present invention has been developed by setting one side of a large space within the capacity range of a crane from outside the building as a steel frame assembly zone, and placing one unit of the roof steel truss. A traveling traction device with a jig and a cylindrical moving shoe are attached to this unit, and a traveling rail and a reaction rail are installed in parallel on the beam in the girder direction. Using force, engage the above-mentioned traveling rail and slide it by two unit widths, then place the second unit in the empty space, connect both units with a steel member, and assemble a total of three units. Slide the 2 unit width again and proceed in the same manner sequentially to erect the steel truss, and then fix the moving shoe to the traveling rail so that it can rotate and prevent axial movement. The main idea is that after the slide is completed, it can be fixed as it is and can be supported by a pin, which can further reduce construction costs, improve safety and construction accuracy, and shorten construction time. The purpose is to

る。 As explained above, the steel truss according to the present invention
According to the traveling construction method, when constructing a steel frame roof A in a large space, the unit 1 with the mobile shoe 14 attached is assembled on the ground and lifted up with a crane or the like, and the upper end of the gable side of one side of the frame is lifted. This was placed on the traveling rails 6, 6 that had been laid in advance on the beams 5, 5 in the girder direction, and the moving shoes 14 were engaged with them, and they were placed in parallel on the beams 5, 5 together with the traveling rails 6. The reaction force is absorbed by the reaction rail 8 with the reaction pin 7, and the unit 1 is slid by the traveling traction device 15 connected to the front part of the unit 1, and this and the next unit placed thereon are assembled on the scaffold 3 only on the gable side. Steel frame member 4...
Since the units are assembled by connecting them with each other, and the steel roof A is constructed by connecting them in the same way as above by sliding two unit widths one after another, the temporary shoring and scaffolding can be made wider than in the conventional example. In addition, since there is no need to leave unsatisfactory construction work behind the crane and scaffolding on the arena floor, it goes without saying that it is possible to significantly reduce construction costs and shorten the construction period. Especially when using the present invention, it is possible to Since the support pin as the column base is used as the moving shoe 14,
Wheels are no longer required, so the work of removing wheels and rails after sliding the unit can be omitted, and once sliding is complete, all units in the frame can be fixed in the same position without the need to raise or lower them, thereby reducing fixing work. It is easy to use, and it also makes it easier to move the shoe 1.
4 has a cylindrical shape, so the contact area with the running rail 6 is small and it is advantageous for sliding, so safety and movement accuracy (construction accuracy) can be significantly improved compared to conventional construction methods of this type, and the reaction force can be further reduced. Since there is no need for rods and reaction force reinforcement work, there are notable advantages such as the ability to save labor and reduce costs for the moving frame.
