Description

  The present invention relates to a construction method for a multi-layer building in a limited area.

  The so-called "precast member method" is a precast manufacturer's standardized work flow and modularized molds that quickly and accurately produce precast members such as precast columns, precast beams and precast laminates. It is to carry out accurate transportation management by assembling precast members that have already been completed and constructing a building. The construction of the outermost structure and the top laminate (roof) on the opposite sides of the building is completed first in order to build the building faster and to fully utilize the building constructed using the precast member method. In the meantime, it becomes a space that is not affected by the weather, and furthermore, a hierarchy in the space between them is built, and at the same time, interior decoration, hydroelectric pipes, establishment of production facilities, etc. are enforced, effectively reducing construction work time Buildings for applications such as production, sales, and residence can be provided quickly.

  However, with the above-described conventional technology, when constructing in a limited area close to the area where the building density is high or cliffs, watersides, etc., it is difficult to obtain usable land and space other than the planned construction site, Compared with raw materials such as gravel, rebar, concrete, etc., already completed precast members cannot change the form and are heavy, so it is necessary to hang them with a highly reliable transport device, If the roof of the building is complete, the use of large grounded self-propelled suspension equipment is restricted, and under these circumstances it is necessary to consider the full use of leveling and the building construction steps .

Therefore, the present inventor considered that the above-mentioned drawbacks can be improved, and as a result of intensive studies, the present inventor has arrived at a proposal of the present invention that effectively improves the above-described problems by rational design.

[First Embodiment]
As shown in FIG. 1, the limited area 100 is set as leveling, and materials, equipment and generated waste necessary for leveling are taken in and out from the advancing side 120. In consideration of fluency, it is more preferable that the leveling work is performed in the direction away from the advance side 120, that is, from the depth side 130 in FIG.

  Next, as shown in FIG. 2, the precast pillar 210 is built in a predetermined position toward the direction along which the two long sides approach each other, that is, toward the center of the limited area 100, as shown in FIG. In addition, the precast beam 220 is built between the precast pillars 210 that have already been built, and the precast laminated board 230 is built between the precast beams 220, thereby forming the first-stage building structure 200. As shown in FIG. 4, such a first stage building structure 200 is constructed from one to several layers based on the design of the building. After that, as shown in FIG. 5, the roof layer of the building is constructed from the second-stage building structure 300 on the first-stage building structure 200 on each side. Considering the loadable weight of the first stage building structure 200, the precast column 210 and the precast beam 220 adopted by the second stage building structure 300 on the first stage building structure 200 are thinner and lighter steel columns 310, steel beams. It is preferable to employ 320. Therefore, in the present embodiment, the second-stage building structure 300 may be a steel building structure.

  As shown in FIG. 6, a horizontal structure 400 is constructed between the second-stage building structures 300 on both sides, and the horizontal structure 400 is connected horizontally to both sides of the frame body of the second-stage building structures on both sides.
