[Detailed Description of the Invention] The present invention enables the construction of a multi-story building on top of an existing facility without interrupting the operation of the existing facility during the construction period and without being subject to major restrictions from surrounding buildings, etc. This project proposes a method for constructing multi-story buildings that are safe and economical.

例えば、既存の工場の規模を、/〜−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シでなく
、工事期間中、工場の操柴が行なえないので、経済性の
面でのロスが膨大なものとなる。
For example, when expanding the scale of an existing factory from a /~- story to a multi-story building, it would be foolish to demolish the existing factory and build a new one, which would increase the cost of demolition. Since the factory cannot be operated during the construction period, there will be huge economic losses.

従って、既存工場の多層化による工場規模の拡大を図る
にあたっては、既存の工場をそのまi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
シ現夾的でもある。
Therefore, when attempting to expand the scale of an existing factory by making it multi-layered, it is desirable and practical to leave the existing factory as it is and build a multi-story factory surrounding it.

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. Not only steel frames, but also bolts or books that fall can break through the roof, making it extremely difficult to ensure safety.

In addition, since the extension will surround the existing factory, it will not be a large-span building, and since a multi-story building will be constructed above the existing factory, the overall ground clearance will be low compared to the number of additional floors. Lifting steel frames from one area of an existing factory requires a large crane with a large working radius and lifting height, which is disadvantageous in terms of cost. Additionally, if the Naruto site of the existing factory is available, large cranes can be used, but in many cases there is not enough space for one area.

The present invention solves the above-mentioned problems by effectively utilizing the so-called traveling method, which is a known method for bridging steel roofs of large spaces such as gymnasiums, and a small crane that can travel on the roof. This is the book that developed the method for constructing a new multi-story structure, in which pillars are erected at predetermined intervals on both sides of an existing facility, and rails are installed on beams in the direction of the girders that are built between these pillars. On the other hand, a work gantry is assembled on the outside of the side of the existing facility in the direction of the girder, and the girder, the small beam connecting the girders, the deck plate or the Keeneton plate, and the temporary support girder are assembled on the work gantry. Slide the same unit a predetermined distance along the rail,
Next, assemble a similar unit on the empty work platform and add it to the unit F that was slid earlier, slide these by the width of the added unit, and then assemble the unit, add to the previous unit, and slide it. #Repeat in order to construct a working floor covering the entire upper part of the existing facility, then construct a concrete floor by placing and pouring concrete on this working floor, and after that, It is unique in that the upper steel frame will be erected using the existing lanes, and a multi-story building will be built on top of the existing facility.
