た。[Problems to be solved by the invention] Therefore, when an existing building is used, there is an inconvenience of having to move to another place until the new building is completed. There were many problems, such as not only being extremely expensive for building usage fees, but also not being able to perform sales normally until the settlement site was reached.
このような問題を解決する手段として、既設施設の上に

のであった。As a means for solving such a problem, it is disclosed in Japanese Examined Patent Publication No. 61-14302 that a frame is laid over an existing facility. In this case, a pillar erected on both sides of the existing facility. While installing rails on beams in the girder direction installed between them, it is necessary to assemble work gutters on the side of the existing facility, and at the work gantry, girders, girders, deck plates, temporary beams, etc. are united. After that, the units are sequentially sent out onto the rails to build a work floor over the entire upper part of the existing facility, and then a traveling crane is mounted on the work floor to construct the upper steel frame, which is extremely large-scale. Requires preparation and construction. Therefore, it was extremely difficult to adopt it in urban areas where existing facilities such as small and medium-sized buildings are densely packed.

供することにある。This invention was conceived in order to solve the above-mentioned conventional problems, and its purpose is to construct a rail or temporary beam by constructing a truss with a steel frame beam installed on an existing facility together with a column base. It is possible to span the frame more easily than before without using the existing structure, and it can be applied to existing small and medium-sized facilities in urban areas where the buildings are relatively dense, and it is easy to add a trace of the removal of existing facilities. To provide a new construction method over existing facilities.

When straddling the frame over the existing facility, a steel diagonal member is attached to the steel beam near the existing facility from the base of the column, and the steel frame is installed between the steel diagonal member and the column and above the steel beam and the upper layer. A diagonal member is placed between the beam and the upper and lower steel beams together with the column base to form a truss, and a truss beam with a large span of one layer is formed. It is in building.

To create. Next, as shown in FIG. 4, steel columns 14 and 14 are erected, joined to the intermediate steel beams 11 and 11 described above, and further steel beams 15 and 16 for each layer are erected to perform the lower-layer skeleton. . After the construction of steel beams, slabs and wall slabs will be constructed in sequence. When the skeleton of the pillars and beams is finished in a certain block, the diagonal members of the large span truss beams and the diagonal members of the columns are removed and used as members for constructing the frame of the existing building traces. The size and cross-section of the newly constructed part and the diagonal members are pre-aligned so that they can be diverted without processing. If alignment is not possible, some processing is performed before diverting.

［発明の効果］ この発明は上述のように、既存施設の上に新しい建物を
跨設してなることから、下記のごとき効果を奏する。[Effect of the Invention] As described above, the present invention has the following effects because a new building is laid over an existing facility.
○ 新築工事中でも既存施設をそのまま継続使用でき、
移転費用や建物の使用料を節減できる。○ Even during new construction work, existing facilities can be used as they are,
Relocation costs and building usage fees can be saved.
○ 既存施設の建替が後に生じたときには、既存施設を
撤去してその跡に増設を行えばよく、また先行構造物と
接続して一体化を図ることができる。○ When the existing facility is rebuilt later, the existing facility can be removed and added to the site, and it can be connected to the preceding structure for integration.
○ 増設に特別な手段を要せぬことから、更地から建築
を始める在来の建築と何ら変るところがなく、工期が特
に長くなるようなこともない。○ Since no special means is required for expansion, there is no difference from conventional construction that starts from a vacant lot, and the construction period will not be particularly long.
○ 架構の１層分をトラスとしてなるため、柱脚部のト
ラスと相俟って、既存施設上に跨設された大スパンのも
のでありながら堅牢である。-Because one layer of the frame is used as a truss, it is a large span spanning over the existing facility in combination with the truss of the column base, but it is robust.
○ トラス梁の上弦材となる上梁をＰＣ鋼材からなる型
鋼により構成し、また下弦材となる下梁にＰＣ鋼線を配
