本発明は、既存の施設の上部に、工事期間中、
既存施設の操業を中断することなく、しかも、周
囲の建物等によつて大きな制約を受けることな
く、多層階建築物を構築できる安全性、経済性に
優れた多層階建築物の構築方法を提案するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for installing a
We propose a method for constructing multi-story buildings that is safe and economical, allowing for the construction of multi-story buildings without interrupting the operation of existing facilities and without being severely restricted by surrounding buildings. It is something to do.
例えば、既存の工場の規模を、１〜２階建から
多層建へと拡大する場合、既存の工場を解体して
新築していたのでは、解体に要する費用がコスト
増となるばかりでなく、工事期間中、工場の操業
が行なえないので、経済性の面でのロスが膨大な
ものとなる。 For example, when expanding the size of an existing factory from a one- to two-story building to a multi-story building, demolishing the existing factory and building a new one would not only increase the cost of demolition, but also increase the cost of demolition. During the construction period, the factory will not be able to operate, resulting in huge economic losses.
従つて、既存工場の多層化による工場規模の拡
大を図るにあたつては、既存の工場をそのまま残
し、これを取り囲むように多層階の工場を増築す
ることが望ましく、より現実的でもある。 Therefore, when expanding the scale of an existing factory by making it multi-layered, it is desirable and more practical to leave the existing factory as it is and build a multi-story factory around it.
しかし、工場建屋の多くは、屋根構造が多層階
建築物を構築する際の作業床として利用できるよ
うな耐力を備えておらず、殊に、折版屋根やスレ
ート葺の屋根の場合には、鉄骨類は勿論、ボルト
１本落としても、屋根を突き破る可能性があり、
安全確保が非常に困難である。 However, the roof structure of many factory buildings does not have enough strength to be used as a working floor when constructing multi-story buildings, especially in the case of folded roofs or slate roofs. Dropping a single bolt, let alone a steel frame, could pierce the roof.
It is extremely difficult to ensure safety.
また、既存の工場を取り囲む状態に増築するの

囲の敷地が十分に利用できる場合であれば、大型
クレーンを使用できるが、周囲の敷地に余裕のな
いケースが多い。 Additionally, since the extension will surround the existing factory, the building will have a large span, and since a multi-story building will be constructed above the existing factory, the overall ground clearance will be high compared to the number of additional floors. Lifting steel frames from around the existing factory would require a large crane with a large working radius and lifting height, which would be disadvantageous in terms of cost. Additionally, if there is sufficient land around an existing factory, large cranes can be used, but in many cases there is not enough space around the existing factory.

点に特徴がある。 The present invention solves the above-mentioned problems by effectively utilizing the so-called traveling method, which is a known method for constructing steel roofs for large spaces such as gymnasiums, and a small crane that can travel on the roof. This method has been developed to construct a new multi-story structure that can be constructed by erecting columns at specified intervals on both sides of an existing facility, and installing rails on beams in the direction of the girder installed between these columns. On the other hand, a work gantry is assembled on the outside of one side of the existing facility in the girder direction, and the girders, small beams connecting the girders, deck plates or keystone plates, temporary support beams, etc. assembled on the work gantry are assembled on the outside of one side of the existing facility in the girder direction. Slide the new unit a predetermined distance along the rail, then assemble a similar unit on the empty work platform and add it to the previously slid unit, slide these by the width of the added unit, and hereafter refer to the unit as follows. Assembling, adding to the previous unit, and sliding are repeated in order to construct a working floor that spans the entire upper part of the existing facility.Next, reinforcement is placed and concrete is placed on this working floor to construct a concrete floor. However, after that, a traveling crane mounted on the concrete floor is used to erect the upper steel frame, which is unique in that a multi-story building is constructed on top of the existing facility.

It is configured to slide at a position several millimeters (for example, about 5 mm) lower than the original position. Therefore, when fixing the work floor C, simply lift one end of each girder by a few millimeters by using a jack to remove the reaction force from the beam 3, and the bolt holes provided in the girder and the joint web plate 17 can be connected. The heights can be matched, and in this state, the two are joined via the splints 19a and 19b, and the rail 4 can be easily extracted from the notch 18. After removing the rail 4, the notch 1
The girder and the joint web plates 17 are joined together via the splint plate 19c that closes the joint part 8.
