この発明は地中連続壁を利用した建物およびその施工法
に関するもので、近隣の建物等と近接させて施工する場
合等に適用できる。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a building using an underground continuous wall and its construction method, and can be applied to cases where the building is constructed in close proximity to neighboring buildings, etc.
市街地等では土地の価格が高く、土地の有効利用が望ま
れること、さらに耐火建築の奨励、駐車場確保といった
ことから、地下1〜6階の鉄筋コンクリートビルが多く
建設されるようになってきている。In urban areas, land prices are high and effective use of land is desired, as well as the need to encourage fire-resistant construction and secure parking lots, so many reinforced concrete buildings with 1 to 6 floors underground are being constructed. .
しかし、基礎工事等における振動、騒音の問題や地盤沈
下による近隣建物への影響といったトラブルが多く、こ
れらを回避するため地中連続壁工法が利用される。However, there are many problems such as vibration and noise problems during foundation construction and the impact on neighboring buildings due to ground subsidence, and to avoid these problems, underground continuous wall construction method is used.
地中連続壁工法は低振動、低騒音の施工が可能であり、
壁体としての剛性も大きく、また施工時に他の構造物と
近接して施工でき、土地の有効利用が図れるといった利

街地工事を中心として施工実績が伸びている。The underground continuous wall construction method enables construction with low vibration and low noise.
It has the advantage of being highly rigid as a wall, and can be constructed close to other structures during construction, allowing for effective use of land. □This type of continuous underground wall construction method involves, for example, excavating using a multi-axis auger, injecting and stirring a hardening phase such as mortar to create a fill mortar wall, and then creating a fill mortar wall by applying stress to the H-section steel before hardening. There is a construction method such as inserting a wall, etc., which has high water-stopping properties and wall strength, and the cost is about the same as the method of burying sheet piles, so the construction results are increasing mainly in urban construction.

従って外壁間の距離りも決定されてしまう。この場合の
外壁間の距離りは地中連続壁1の壁厚や応力拐としての
H形鋼8の断面寸法等によっても多少異なるが、一般的
には70〜80cIL程度である。Continuous underground walls such as fill mortar walls use excavating machines such as auger machines during construction, so as shown in the off-line diagram and Figure 8, it is difficult to prevent walls from entering the ground from nearby existing buildings 9 and obstacles. Restricted by the distance to underground wall 1,
Therefore, the distance between the outer walls is also determined. The distance between the outer walls in this case varies somewhat depending on the wall thickness of the underground continuous wall 1, the cross-sectional dimension of the H-beam 8 as a stress relief, etc., but is generally about 70 to 80 cIL.
この発明では上述のように制約される外壁間の距離を狭
めるよう工夫し、さらに有効な土地利用を可能とするこ
とを目的としたものである。The purpose of this invention is to reduce the distance between outer walls, which is restricted as described above, and to enable more effective land use.

This pillow type 4 is housed.

することができる。In other words, the pillars of the underground part 2 of the frame are shaped to protrude outward from the outer wall surface, and therefore the pillars 10 of the above-ground part that are continuous with this can also be built closer to the site boundary line by the amount of the protrusion of the pillow type 4. The site can be utilized to the maximum extent even if there is a building to be built.

A panel-shaped connecting member 5 is built into the underground continuous wall 1 before hardening, and after hardening, a recess 3 is formed in the underground continuous wall 1 by recessing the built-in part side 5 and the frame side of the stand. , and the pillar wall 4 of the underground part 2 of the building frame can be constructed within the recess 3 .

できる。The built-in part *A5 is made by connecting webs of parallel H-beams 6 with a partition plate 7 such as a steel plate, and can be manufactured in advance at a factory. The structure side of the construction section 5 is excavated to the position of the partition plate 7, and the pillow type 4 protruding from the outer wall surface of the underground section 2 of the structure is housed. The pillars 10 above the ground can be constructed continuously, and the outer walls 11 can also be positioned on the outside accordingly, so that the building 9 that is close to the ground can be constructed in a continuous manner, compared to the conventional example shown in FIG.
The distance between the outer wall and the outer wall can be reduced by the amount of the protrusion of the pillow shape 4.
