Description
本開示は、基礎・土間一体打ち構造及び基礎・土間一体打設工法に関する。 This disclosure relates to a foundation/slab integrated construction structure and a foundation/slab integrated construction method.
従来、布基礎と、布基礎に隣接する土間・コンクリートとを一体に打設する基礎・土間一体打ち構造及び打設工法が知られている（特許文献１）。
この種の打設工法では、土間の内部の盛土の、布基礎側の縁に沿って、捨て型枠を設けることにより、盛土を土留めするのが一般的である。
Conventionally, a foundation/floor integrated construction structure and construction method have been known in which a continuous foundation and a concrete floor adjacent to the continuous foundation are poured together (Patent Document 1).
In this type of pouring method, it is common to retain the embankment by providing a temporary formwork along the edge of the embankment inside the earthen floor on the side of the spread footing.
しかしながら、従来の技術では、土間の盛土に転圧を掛ける際に、捨て型枠が移動又は変形し、布基礎の断面形状に影響を与える可能性がある。
そこで、本開示の目的は、上述した従来の技術が有する課題を解消し、捨て型枠の移動又は変形を抑えて、布基礎の断面形状に影響を与えない、基礎・土間一体打ち構造及び打設工法を提供することにある。
However, with conventional techniques, when compacting the embankment of the earth floor, the temporary formwork may move or deform, which may affect the cross-sectional shape of the continuous footing.
Therefore, the object of the present disclosure is to provide a foundation/floor integrated pouring structure and pouring method that eliminates the problems associated with the above-mentioned conventional technologies, suppresses movement or deformation of the temporary formwork, and does not affect the cross-sectional shape of the slab footing.
本開示は、盛土に沿う捨て型枠と、前記捨て型枠の前記盛土と反対側に位置する布基礎とを備え、少なくとも前記布基礎のベース部と、前記布基礎に隣接する土間・コンクリートとを一体に打設する基礎・土間一体打ち構造において、前記捨て型枠は、複数の堰板と、堰板同士を平面視環状に結合する結合板と、を備え、前記結合板は、前記堰板の側面に結合され、かつ平面視環状に枠組みして構成されることを特徴とする。 捨て型枠は、堰板同士を平面視環状に結合する結合板を備えるため、土間の盛土に転圧 を掛ける場合に、捨て型枠が移動又は変形するのを抑制し、布基礎の断面形状に影響を与 えることを抑制できる。また結合板は、平面視環状に結合されるため、縦の支保工を用いた場合と比較して、横方向だけで補強でき、布基礎のベース部の断面形状への影響を抑えることができる。
The present disclosure provides a foundation-slab integrated pouring structure comprising a temporary formwork that follows the embankment and a slab located on the opposite side of the slab from the embankment. At least the base of the slab and the slab/concrete adjacent to the slab are poured together. The slab comprises a plurality of sheathing plates and connecting plates that connect the sheathing plates to each other in a circular shape in plan view . The connecting plates are connected to the sides of the sheathing plates and form a circular frame in plan view . Because the slab comprises connecting plates that connect the sheathing plates to each other in a circular shape in plan view, the slab is prevented from moving or deforming when the slab is compacted, minimizing the impact on the cross-sectional shape of the slab. Furthermore, because the connecting plates are connected to each other in a circular shape in plan view, reinforcement is provided only horizontally compared to the case of using vertical shoring, minimizing the impact on the cross-sectional shape of the slab base.
前記結合板は、前記堰板の上部を平面視環状に結合してもよい。
堰板の上部を結合するため、布基礎のベース部に結合板が残ることがなく、布基礎の断面形状に影響を与えることを抑制できる。
The connecting plate may connect the upper portions of the dam plates in a ring shape in a plan view.
Since the upper part of the weir plate is connected, no connecting plate remains at the base of the slab, which reduces the impact on the cross-sectional shape of the slab.
前記結合板は、前記堰板の側面に配置され、前記結合板と前記堰板とをボルトで結合してもよい。
結合板は、堰板の側面に配置されるため、結合板と堰板とをボルトで結合するための施工性が向上する。
The connecting plate may be disposed on a side surface of the dam plate, and the connecting plate and the dam plate may be connected to each other with bolts.
Since the connecting plate is placed on the side of the dam plate, workability is improved for connecting the connecting plate and the dam plate with bolts.
前記結合板は、前記堰板の側面に配置され、前記結合板の係合部を前記堰板の天端に係合させて、前記結合板と前記堰板とを結合してもよい。
結合板の係合部を堰板の天端に係合させるだけで、結合板と堰板とを結合できるため、結合板と堰板とを結合する施工性が向上する。
The connecting plate may be disposed on a side surface of the dam plate, and an engaging portion of the connecting plate may be engaged with a top edge of the dam plate to connect the connecting plate and the dam plate.
The connecting plate and the dam plate can be connected simply by engaging the engaging portion of the connecting plate with the top end of the dam plate, which improves the ease of construction when connecting the connecting plate and the dam plate.
盛土に沿う捨て型枠の複数の堰板同士を結合板により平面視環状に結合し、前記捨て型枠の前記盛土と反対側に布基礎を配置し、少なくとも前記布基礎のベース部と、前記布基礎に隣接する土間・コンクリートとを一体に打設してもよい。
堰板同士を結合板により平面視環状に結合するため、盛土に転圧を掛ける場合、捨て型枠の移動又は変形が抑制され、布基礎の断面形状に影響を与えない。
Multiple weir plates of a temporary formwork that runs along the embankment can be connected together in a ring shape in plan view using connecting plates, and a strip footing can be placed on the opposite side of the temporary formwork from the embankment, with at least the base of the strip footing and the earthen floor/concrete adjacent to the strip footing being poured together.
The weir plates are connected to each other by connecting plates in a ring shape when viewed in plan, so when the embankment is compacted, movement or deformation of the temporary formwork is suppressed, and the cross-sectional shape of the slab footing is not affected.
前記結合板は、前記堰板の上部を平面視環状に結合してもよい。
堰板の上部を結合するため、布基礎のベース部に結合板が残ることがなく、布基礎の断面形状に影響を与えることを抑制できる。
The connecting plate may connect the upper portions of the dam plates in a ring shape in a plan view.
Since the upper part of the weir plate is connected, no connecting plate remains at the base of the slab, which reduces the impact on the cross-sectional shape of the slab.
本開示では、捨て型枠は複数の堰板同士を平面視環状に結合する結合板を備えるため、土間の盛土に転圧を掛ける際に、捨て型枠の移動又は変形が抑えられ、布基礎の断面形状への影響を抑えることができる。また結合板は、平面視環状に結合されるため、縦の支保工を用いた場合と比較して、横方向だけで補強でき、布基礎のベース部の断面形状への影響を抑えることができる。 In this disclosure, the temporary formwork is equipped with connecting plates that connect multiple dam panels together in a circular shape when viewed from above, which prevents the temporary formwork from moving or deforming when compacting the embankment on the floor, minimizing the impact on the cross-sectional shape of the continuous footing. Furthermore, because the connecting plates are connected in a circular shape when viewed from above, reinforcement can be provided only in the horizontal direction compared to when vertical shoring is used, minimizing the impact on the cross-sectional shape of the continuous footing base.
以下、図面を参照して本開示の実施の形態について説明する。
図１は、基礎・土間一体打ち構造１を示す。
一体打ち構造１は、住宅や商工業施設等となる建物に適用される。一体打ち構造１は、捨て型枠２と、布基礎３と、盛土４の上面を覆う土間・コンクリート５とを備える。布基礎３は、プレキャストコンクリート６とベース部７からなり、ベース部７は盛土４の上面を覆う土間・コンクリート５と一体に打設される。
Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.
FIG. 1 shows a foundation and floor integrated construction structure 1.
The cast-in-place structure 1 is applied to buildings such as residential buildings and commercial and industrial facilities. The cast-in-place structure 1 comprises a temporary formwork 2, a continuous footing 3, and a concrete slab 5 covering the top surface of the embankment 4. The continuous footing 3 is made up of precast concrete 6 and a base 7, and the base 7 is cast integrally with the concrete slab 5 covering the top surface of the embankment 4.
図２、図３は、捨て型枠２の一例を示す。
捨て型枠２は、複数の押出成形セメント板（堰板 ＥＣＰ；Ｅｘｔｒｕｄｅｄ ｃｅｍｅｎｔ ｐａｎｅｌ）１１と、押出成形セメント板１１を結合する結合板１２とにより構成される。
押出成形セメント板１１は軽量で高い剛性をする。堰板にはＡＬＣ材（Ａｕｔｏｃｌａｖｅｄ Ｌｉｇｈｔｗｅｉｇｈｔ ａｅｒａｔｅｄ Ｃｏｎｃｒｅｔｅ）なども適用できる。
2 and 3 show an example of the disposable formwork 2. FIG.
The temporary formwork 2 is composed of a plurality of extruded cement panels (ECPs) 11 and connecting plates 12 that connect the extruded cement panels 11 together.
The extruded cement board 11 is lightweight and highly rigid. ALC (Autoclaved Lightweight Aerated Concrete) material can also be used for the dam board.
押出成形セメント板１１は、図３に示すように、横方向に実（不図示）により結合され、平面視矩形状に枠組されて、布基礎３の内側に配置される。
図１に示すように、押出成形セメント板１１の上部１１Ａは、布基礎３のベース部７の上面７Ａよりも上方に突出している。
結合板１２は山形鋼であり、該上部１１Ａの側面１１Ｂにボルト１３で結合される。結合板１２は、図３に示すように、複数本の山形鋼材１２ａ～１２ｅを平面視環状に枠組して構成される。山形鋼材１２ａ～１２ｅは連結片１４で連結される。
結合板１２の結合は、一つの押出成形セメント板１１に対し１本のボルト１３で結合する。結合の施工性が向上する。なお一部破線Ｌで示すように、対向する押出成形セメント板１１同士を一本のボルト１３で結合してもよい。
As shown in FIG. 3, the extruded cement boards 11 are joined together laterally by means of screws (not shown), framed in a rectangular shape in plan view, and placed inside the continuous footing 3.
As shown in FIG. 1 , an upper portion 11</b>A of the extruded cement board 11 protrudes above an upper surface 7</b>A of the base portion 7 of the continuous footing 3 .
The connecting plate 12 is an angle iron, and is connected to the side surface 11B of the upper portion 11A with bolts 13. As shown in Figure 3, the connecting plate 12 is formed by arranging a plurality of angle irons 12a to 12e in a ring-like frame in a plan view. The angle irons 12a to 12e are connected by connecting pieces 14.
The connecting plates 12 are connected with one bolt 13 per extruded cement board 11, improving workability of the connection. As shown by the dashed line L, opposing extruded cement boards 11 may also be connected with one bolt 13.
本構成では、結合板１２は、押出成形セメント板１１の上部１１Ａの側面１１Ｂにボルト１３で結合したため、少なくとも布基礎３のベース部７には入らない。
そのため、布基礎３の断面形状に影響を与えることがない。また、結合板１２は、環状に枠組されるため、縦の支保工を用いた場合と比較し、横方向で補強でき、布基礎３のベース部７の断面形状に影響を与えることがない。
本実施の形態では、布基礎３の強度が確保される。
In this configuration, the connecting plate 12 is connected to the side surface 11B of the upper portion 11A of the extruded cement board 11 with bolts 13, and therefore does not enter at least the base portion 7 of the continuous footing 3.
Therefore, it does not affect the cross-sectional shape of the continuous footing 3. Furthermore, because the connecting plate 12 is framed in a ring shape, it can be reinforced in the horizontal direction compared to when vertical shoring is used, and the cross-sectional shape of the base portion 7 of the continuous footing 3 is not affected.
In this embodiment, the strength of the continuous foundation 3 is ensured.
図４Ａ～図４Ｃは、基礎・ 土間一体打ち構造１の施工手順を示す。
まず、図４Ａに示すように、地盤上面レベルＧＬ下に布基礎３を配置する根切り凹部８を掘削する。根切り凹部８に隣接して残る盛土４の縁に沿って捨て型枠２を配置する。捨て型枠２の下端部は、根切り凹部８に埋設する。
根切り凹部８にベース部７を打設する基礎型枠１５を設置する。また、基礎型枠１５と捨て型枠２との間に、プレキャストコンクリート６を配置する。
4A to 4C show the construction procedure for the foundation and floor integrated construction structure 1.
First, as shown in Figure 4A, a recess 8 for placing the continuous footing 3 is excavated below the ground surface level GL. A temporary formwork 2 is placed along the edge of the remaining embankment 4 adjacent to the recess 8. The lower end of the temporary formwork 2 is buried in the recess 8.
A foundation formwork 15 is installed in the excavation recess 8 to pour the base portion 7. In addition, precast concrete 6 is placed between the foundation formwork 15 and the temporary formwork 2.
つぎに、図４Ｂに示すように、盛土４の上に土間・コンクリート５を打設する。土間・コンクリート５は、布基礎３のプレキャストコンクリート６と捨て型枠２と基礎型枠１５との間に打設し、布基礎３のベース部７をプレキャストコンクリート６と一体打設する。コンクリートの養生後に、図４Ｃに示すように、基礎型枠１５を脱型し、成形された布基礎３の土間・コンクリート５とは反対側の空間に土を埋め戻す。 Next, as shown in Figure 4B, the concrete floor 5 is poured on top of the embankment 4. The concrete floor 5 is poured between the precast concrete 6 of the strip footing 3, the temporary formwork 2, and the foundation formwork 15, and the base portion 7 of the strip footing 3 is poured integrally with the precast concrete 6. After the concrete has cured, as shown in Figure 4C, the foundation formwork 15 is removed, and soil is backfilled into the space on the opposite side of the formed strip footing 3 from the concrete floor 5.
本実施の形態では、盛土４に沿う捨て型枠２の複数の押出成形セメント板１１同士を、結合板１２により平面視環状に結合し、捨て型枠２の盛土４と反対側に布基礎３を配置し、プレキャストコンクリート６と、ベース部７と、布基礎３に隣接する土間・コンクリート５とを一体に打設する。そのため、土間の盛土４に転圧を掛ける場合、捨て型枠２が移動又は変形するのを抑制し、捨て型枠２が膨らむことがなく、布基礎３の断面形状に影響を与えることを抑制できる。
この場合、結合板１２は、押出成形セメント板１１の上部１１Ａの側面１１Ｂに平面視環状に結合することが望ましい。
In this embodiment, multiple extruded cement boards 11 of the temporary formwork 2 that runs along the embankment 4 are joined together in a ring shape in plan view by connecting plates 12, a strip footing 3 is placed on the side of the temporary formwork 2 opposite the embankment 4, and the precast concrete 6, base 7, and the floor concrete 5 adjacent to the strip footing 3 are poured together. Therefore, when compacting the floor embankment 4, the temporary formwork 2 is prevented from moving or deforming, and the temporary formwork 2 does not expand, thereby preventing any impact on the cross-sectional shape of the strip footing 3.
In this case, it is desirable that the connecting plate 12 be connected to the side surface 11B of the upper portion 11A of the extruded cement board 11 in a ring shape when viewed from above.
図５Ａ～図５Ｃは、別の施工手順を示す。
この基礎・土間一体打ち構造１は、まず、図５Ａに示すように、地盤上面レベルＧＬ下に布基礎３を配置する根切り凹部８を掘削する。
根切り凹部８に隣接して残る盛土４の縁に沿って捨て型枠２を配置する。捨て型枠２の下端部は、根切り凹部８に埋設する。根切り凹部８に、基礎型枠１５の他に布基礎３を打設する基礎型枠１６、１７を配置する。
捨て型枠２の形態は、上記実施形態と同じである。
5A-5C show another construction procedure.
In this integrated foundation and floor construction 1, first, as shown in FIG. 5A, a root-cut recess 8 in which the continuous footing 3 is to be placed is excavated below the ground surface level GL.
A temporary formwork 2 is placed along the edge of the remaining fill 4 adjacent to the excavation recess 8. The lower end of the temporary formwork 2 is buried in the excavation recess 8. In addition to the foundation formwork 15, foundation formworks 16 and 17 for pouring the strip footing 3 are placed in the excavation recess 8.
The form of the disposable formwork 2 is the same as that of the above embodiment.
つぎに、図５Ｂに示すように、布基礎３の基礎型枠１６、１７内にコンクリートを打設すると共に、盛土４上にも土間・コンクリート５を打設する。コンクリートの養生後に、図５Ｃに示すように、基礎型枠１５、１６、１７を脱型し、成形された布基礎３の土間・コンクリート５とは反対側の空間に土を埋め戻す。
本実施形態では、プレキャストコンクリート６を用いることなく、土間・コンクリート５と共に、ベース部７、起立部９を備える布基礎３を一体に打設できる。
Next, as shown in Figure 5B, concrete is poured into the foundation formwork 16, 17 of the strip footing 3, and the concrete floor 5 is also poured on the embankment 4. After the concrete has cured, the foundation formwork 15, 16, 17 are removed, and the space on the opposite side of the formed strip footing 3 from the concrete floor 5 is backfilled with soil, as shown in Figure 5C.
In this embodiment, the strip footing 3 having the base portion 7 and the rising portion 9 can be poured together with the floor/concrete 5 without using precast concrete 6.
いずれの施工手順の場合も、結合板１２は、押出成形セメント板１１の上部１１Ａの側面１１Ｂにボルト１３で結合したため、布基礎３のベース部７に入らない。
そのため、布基礎３の断面形状に影響を与えることがない。
結合板１２は、環状に枠組されるため、縦の支保工を用いた場合と比較し、横方向で補強でき、布基礎３のベース部７の断面形状に影響を与えることがない。
In either construction procedure, the connecting plate 12 is connected to the side 11B of the upper part 11A of the extruded cement board 11 with bolts 13, and therefore does not enter the base part 7 of the continuous footing 3.
Therefore, the cross-sectional shape of the continuous foundation 3 is not affected.
Because the connecting plate 12 is framed in a ring shape, it can be reinforced horizontally compared to when vertical supports are used, and does not affect the cross-sectional shape of the base portion 7 of the continuous footing 3.
図６Ａ～図６Ｃは、別実施の形態を示す。
捨て型枠２の押出成形セメント板１１は、上記実施の形態と同様に、横方向に実（不図示）により結合され、平面視矩形状に枠組され、布基礎３の内側に配置される。
結合板１２は押出成形セメント板１１の側面１１Ｂに配置される。
結合板１２はフック状の係合部１２Ｆを備え、係合部１２Ｆを押出成形セメント板１１の天端１１Ｃに係合させて、結合板１２と押出成形セメント板１１とを結合する。
この実施の形態では、フック状の係合部１２Ｆを押出成形セメント板１１の天端１１Ｃに引っ掛けて係合できるので、図２、図３に示すようにボルト１３で結合する場合に比べて、施工性が向上する。
6A to 6C show another embodiment.
As in the above embodiment, the extruded cement boards 11 of the temporary formwork 2 are joined together horizontally with screws (not shown), framed into a rectangular shape in plan view, and placed inside the continuous footing 3.
The connecting plate 12 is placed on the side 11B of the extruded cement plate 11.
The connecting plate 12 has a hook-shaped engaging portion 12F, and the engaging portion 12F is engaged with the top end 11C of the extruded cement board 11 to connect the connecting plate 12 and the extruded cement board 11.
In this embodiment, the hook-shaped engaging portion 12F can be hooked onto the top end 11C of the extruded cement board 11, thereby improving workability compared to when the board is connected with a bolt 13 as shown in Figures 2 and 3.
図７Ａ～図７Ｃは、さらに別実施の形態を示す。
結合板１２は、押出成形セメント板１１の天端１１Ｃに配置される。
結合板１２は、複数枚の平板状の部材１２Ｘ～１２Ｚからなり、これらを連結片１４で連結し、平面視環状に枠組されて構成される。
いずれの実施の形態でも、捨て型枠２は、複数の押出成形セメント板１１同士を平面視環状に強固に結合する結合板１２を備えるため、盛土４に転圧を掛け、或いは、土間・コンクリート５を打設する場合、内部の盛土４が捨て型枠２により土留めされ、捨て型枠２には土圧によるはらみが生じない。
7A to 7C show yet another embodiment.
The connecting plate 12 is placed on the top end 11C of the extruded cement plate 11.
The connecting plate 12 is made up of a plurality of flat plate-like members 12X to 12Z, which are connected by connecting pieces 14 and framed in a ring shape in plan view.
In either embodiment, the temporary formwork 2 is equipped with connecting plates 12 that firmly connect multiple extruded cement boards 11 together in a ring shape when viewed from above, so that when the embankment 4 is compacted or the floor concrete 5 is poured, the internal embankment 4 is retained by the temporary formwork 2, and the temporary formwork 2 does not bulge due to earth pressure.
本実施の形態では、捨て型枠２は、複数の押出成形セメント板１１と、押出成形セメント板１１同士を平面視環状に結合する結合板１２と、を備えるため、盛土４の転圧に耐えかつ安価な材料で盛土４を土留めでき、施工性に優れる。
また、押出成形セメント板１１の上部を平面視環状に結合するため、土間の盛土４に転圧を掛ける際に、捨て型枠２の移動又は変形が抑えられ、布基礎３の断面形状に影響のない、一体打ち構造１となる。
さらに、区画ごとに施工することにより、残土を場外に排出する必要がなく、施工が簡単で、施工コストを低減できる。
In this embodiment, the temporary formwork 2 comprises a plurality of extruded cement boards 11 and connecting plates 12 that connect the extruded cement boards 11 together in a ring shape when viewed from above, so that the embankment 4 can be retained using inexpensive materials that can withstand the compaction of the embankment 4, and is easy to install.
In addition, since the upper part of the extruded cement board 11 is joined in a ring shape when viewed in plan, movement or deformation of the temporary formwork 2 is suppressed when compacting the floor embankment 4, resulting in an integral cast-in-place structure 1 that does not affect the cross-sectional shape of the slab footing 3.
Furthermore, by carrying out construction in sections, there is no need to remove the surplus soil from the site, making construction easier and reducing construction costs.
本実施の形態では、基礎・土間一体打ち構造１は、プレキャストコンクリート６を用いて、布基礎３のベース部７と、盛土４の上面を覆う土間・コンクリート５と、を一体に打設するので、基礎・土間一体打ち構造１を安価に施工できる。
基礎・土間一体打ち構造１において、布基礎３のベース部７の一側面の型枠を、盛土４の土留に用いる捨て型枠２が兼ねるため、コンクリート打設後の布基礎３のベース部７の脱型が不要になる。また、布基礎３にプレキャストコンクリート６を用いた場合、その成形のための基礎型枠１６、１７が不要になり、脱型が不要となる。これにより、一体打ち構造１を、施工性よく、安価にかつ精度良く施工できる。
In this embodiment, the foundation and floor integrated structure 1 is constructed by using precast concrete 6 to integrally cast the base 7 of the strip footing 3 and the floor concrete 5 covering the top surface of the embankment 4, so that the foundation and floor integrated structure 1 can be constructed inexpensively.
In the cast-in-place foundation and slab integral structure 1, the temporary formwork 2 used for retaining the embankment 4 also serves as the formwork for one side of the base portion 7 of the strip footing 3, eliminating the need to strip the base portion 7 of the strip footing 3 after pouring the concrete. Furthermore, if precast concrete 6 is used for the strip footing 3, the foundation formwork 16, 17 for forming it is not required, and stripping is also not required. This allows the cast-in-place structure 1 to be constructed easily, inexpensively, and with high precision.
