Description

本発明は、建物のエントランス庇や外部階段等の比較的荷重負担の少ない平面的な張出部を支持する基礎の構造に係り、当該基礎構造において必要な基礎梁と杭との配置方法と配置構造に関するものである。   The present invention relates to a structure of a foundation that supports a flat overhanging portion with relatively little load load such as an entrance fence of a building or an external staircase, and a layout method and arrangement of foundation beams and piles necessary for the foundation structure. Concerning structure.

従来、図４に示すように、エントランス庇２０は、庇の建物２１から突出した先端の両隅に２本の柱２２で支持される。そして、前記庇２０を囲うように基礎梁２３が四辺周囲に配置される。前記柱２２の直下に杭２４が設けられるものが知られている（特許文献１参照）。   Conventionally, as shown in FIG. 4, the entrance fence 20 is supported by two pillars 22 at both corners of the tip protruding from the fence building 21. And the foundation beam 23 is arrange | positioned around four sides so that the said cage | basket 20 may be enclosed. There is known one in which a pile 24 is provided directly below the pillar 22 (see Patent Document 1).

特開平６−３３０５３２号公報JP-A-6-330532

しかし、従来の建物の張出部を支持する基礎梁と杭との配置方法によれば、四辺周囲に配置した基礎梁の先端側の２個所に柱を設けたので、その柱直下に杭を設けるようにしていることから、杭の本数が２本となっている。これでは、荷重負担が少ないにもかかわらず杭本数が多くなっている。また、杭の支持層の深度が深い場合には、２本分の杭のコストが嵩むことになり、必要支持力に対するコストが高くなるという課題がある。本発明に係る建物の張出部を支持する基礎梁と杭との配置方法と配置構造は、このような課題を解決するために提案されたものである。   However, according to the arrangement method of the foundation beam and the pile supporting the overhanging part of the conventional building, the pillars are provided at the two positions on the tip side of the foundation beam arranged around the four sides. Since it is provided, the number of piles is two. In this case, the number of piles is increased although the load burden is small. Moreover, when the depth of the support layer of a pile is deep, the cost of two piles will increase and there exists a subject that the cost with respect to required support force becomes high. The arrangement method and arrangement structure of the foundation beam and the pile supporting the projecting portion of the building according to the present invention have been proposed in order to solve such a problem.

本発明に係る建物の張出部を支持する基礎梁と杭との配置方法の上記課題を解決して目的を達成するための要旨は、建物の張出部を支持する基礎梁と杭との配置方法において、前記基礎梁のうち建物側から突出させる基礎梁を交差させて配置し、当該基礎梁同士が交差する個所の直下に支持用の杭を配置することである。
前記基礎梁は、平面視してＸ型，Ｖ型，Ｕ型若しくはＷ型に配置して交差させたことを含むものである。
また、建物の張出部を支持する基礎梁と杭との配置構造の要旨は、建物の張出部を支持する基礎梁と杭との配置構造において、前記基礎梁のうち建物側から突出させる基礎梁を交差するように配置して形成され、当該基礎梁同士が交差する個所の直下に支持用の杭が形成されていることである。 The gist for solving the above-mentioned problem of the method of arranging the foundation beam and the pile supporting the overhanging part of the building according to the present invention is as follows. In the arrangement method, the foundation beams that protrude from the building side of the foundation beams are arranged so as to intersect with each other, and a supporting pile is arranged immediately below the portion where the foundation beams intersect.
The foundation beam includes an X-type, a V-type, a U-type, or a W-type when viewed from above and crossed.
Further, the gist of the arrangement structure of the foundation beam and the pile supporting the overhanging portion of the building is that the arrangement structure of the foundation beam and the pile supporting the overhanging portion of the building is projected from the building side of the foundation beam. It is formed by arranging the foundation beams so as to intersect with each other, and a supporting pile is formed immediately below the place where the foundation beams intersect.

本発明の建物の張出部を支持する基礎梁と杭との配置方法と配置構造によれば、杭の本数が従来例に比較して減少することになる。よって、躯体コスト，工期，掘削土量の低減が図れる。負担荷重と杭支持力とのバランスが良くなる。特に地盤が悪く基礎が深い場合には、杭１本のコストが嵩むので、低減効果が増すものである。
庇エリアなどの張出部の中心付近で杭が荷重を受けることになり、床の沈下対策としても有効になる等と言う数々の優れた効果を奏するものである。 According to the arrangement method and the arrangement structure of the foundation beam and the pile supporting the projecting portion of the building of the present invention, the number of piles is reduced as compared with the conventional example. Therefore, it is possible to reduce the frame cost, construction period, and excavated soil volume. The balance between the burden load and pile support force is improved. Especially when the ground is bad and the foundation is deep, the cost of one pile increases, so the reduction effect increases.
The pile will receive a load near the center of the overhanging area such as the dredging area, and it has many excellent effects such as being effective as a countermeasure against floor settlement.

本発明に係る建物の張出部を支持する基礎梁と杭との配置方法は、図１に示すように、建物１の張出部用基礎２における建物側から突出した基礎梁３，…と杭４との配置方法において、前記基礎梁３を平面視してＸ型に配置して、その基礎梁３，３同士が交差する個所の直下に支持用の杭４を配置することである。   As shown in FIG. 1, the arrangement method of the foundation beam and the pile supporting the projecting portion of the building according to the present invention is the foundation beam 3 projecting from the building side in the projecting portion foundation 2 of the building 1. In the arrangement method with the pile 4, the foundation beam 3 is arranged in an X shape in a plan view, and the support pile 4 is arranged immediately below the place where the foundation beams 3 and 3 intersect each other.

前記張出部用基礎２は、建物１から平面的に突出する上部庇５の下位置における地盤部分である。前記基礎梁３は、建物１から突出して上部庇５を支持する柱６，６との間に設けられる基礎梁である。また、前記柱６，６間の基礎梁は符号７で示している。   The overhang portion foundation 2 is a ground portion at a position below the upper eaves 5 protruding in a plane from the building 1. The foundation beam 3 is a foundation beam provided between the columns 6 and 6 that protrude from the building 1 and support the upper eaves 5. The foundation beam between the columns 6 and 6 is denoted by reference numeral 7.

更に、前記柱６は、上部庇５の先端部側において支持するように配設されているものである。こうして、前記杭４を、予め前記基礎梁３，３の交差する点の位置に構築する。その後、基礎梁３，３をＸ型状に形成するものである。そして、地盤を基礎梁３，３の間に埋戻してその上に土間コンクリートを形成する。また、柱６、６と上部庇５とを現場コンクリート打ち、若しくは、プレキャストコンクリート製，鉄骨製の柱等を建て入れなどして構築する。   Further, the column 6 is disposed so as to be supported on the tip side of the upper flange 5. In this way, the pile 4 is constructed in advance at the position where the foundation beams 3 and 3 intersect. Thereafter, the foundation beams 3 and 3 are formed in an X shape. And the ground is backfilled between the foundation beams 3 and 3, and soil concrete is formed on it. Further, the pillars 6 and 6 and the upper frame 5 are constructed by in-situ concrete casting, or by precast concrete or steel frame pillars.

前記杭４を構築する際に、地盤が軟弱であったりして基礎が深いときにはコストが嵩むことになるが、図１に示すように、本発明に係る方法では１本の杭４で済むので、従来例に比較してコストが低減される。このような配置方法により、図１に示す基礎梁と杭との配置構造ができ上がる。Ｘ（クロス）型の基礎梁３，３により、庇下を車寄せとして利用する場合には、繰り返しの活荷重に対する沈下防止としても作用して効果的である。   When the pile 4 is constructed, the cost increases when the ground is soft and the foundation is deep. However, as shown in FIG. 1, the method according to the present invention requires only one pile 4. The cost is reduced as compared with the conventional example. By such an arrangement method, the arrangement structure of the foundation beam and the pile shown in FIG. 1 is completed. When the armpit is used as a carriage by the X (cross) -type foundation beams 3 and 3, it acts effectively as a settlement prevention against repeated live loads.

図２に示すように、建物の張出部を支持する基礎梁と杭との配置方法の他の実施例として、前記基礎梁のうち建物側から突出させる基礎梁３，３を平面視してＶ型に配置して、その突出させた基礎梁３を平面視してＶ型に配置し、その基礎梁３，３同士が交差する個所の直下に支持用の杭４を配置するものである。実施例１のＸ型からの発展形となっている。その他、前記基礎梁３，３は、上記実施例１，２において直線状にＸ型，Ｖ型に配置するだけに限らず、平面視してＵ型若しくはＷ型に配置したり、その他に曲線状のＸ型やＶ型，Ｕ型，Ｗ型等に配置したりして交差させる配置も含むものである。この配置構造も上記実施例１と同様の効果を奏するものである。   As shown in FIG. 2, as another embodiment of the method of arranging the foundation beam and the pile supporting the projecting portion of the building, the foundation beams 3 and 3 that protrude from the building side of the foundation beam are viewed in plan view. The base beam 3 is arranged in a V shape, arranged in a V shape in plan view, and a supporting pile 4 is arranged immediately below the location where the foundation beams 3 and 3 intersect each other. . This is a development from the X type of the first embodiment. In addition, the foundation beams 3 and 3 are not limited to being linearly arranged in the X-type and V-type in the first and second embodiments. This includes arrangements such as X-type, V-type, U-type, W-type, etc. This arrangement structure also has the same effect as the first embodiment.

図３（Ａ），（Ｂ）に示すように、建物１におけるセットバックに、鉄骨造の下屋部分８が有る場合にも、図３（Ｃ），（Ｄ）に示すように、基礎梁３，３を平面視して直線状のＸ型，Ｖ型，Ｕ型若しくはＷ型、その他に、曲線状のＸ型やＶ型，Ｕ型，Ｗ型等に配置し交差させて配置して、杭４を１本にするものである。このように、本発明の配置方法を適用することが可能である。この場合にも、上記実施例１，２と同様の作用・効果を奏するものである。   As shown in FIGS. 3 (A) and 3 (B), even in the case where the set-back in the building 1 has the steel-structured lower part 8, as shown in FIGS. 3 (C) and (D), the foundation beam 3 and 3 are arranged in a straight X-type, V-type, U-type or W-type in a plan view, and in a curved X-type, V-type, U-type, W-type, etc. The pile 4 is made into one. Thus, it is possible to apply the arrangement method of the present invention. Also in this case, the same operation and effect as the first and second embodiments are exhibited.

本発明に係る建物の張出部を支持する基礎梁と杭との配置方法と配置構造は、比較的荷重負担の小さい突出物を支持する場合の基礎部分に広く適用することができてコスト低減をもたらすものである。   The arrangement method and arrangement structure of the foundation beam and the pile supporting the projecting portion of the building according to the present invention can be widely applied to the foundation portion in the case of supporting the projecting object having a relatively small load burden, thereby reducing the cost. It is what brings.
