Description

【0001】
【産業上の利用分野】
本発明は、プレキャストコンクリート連結部材に係り、地下室の擁壁と建物の基礎とを連結する際に利用できる。
【0002】
【背景技術】
新しい居住方式の実現等の要望から地下室を備えた建物が増えている。
この建物の地下室をつくる際には、地下室用の縦穴を掘削し、そこに例えば現場施工、あるいは予め工場で型枠にコンクリートスラリーを打設して製造したプレキャストコンクリート(以下、PCという)製の擁壁を設けて地下室の外部を形成し、次いで擁壁外周の縦穴に土を入れ埋め戻し作業を行っている。
また、建物の基礎をつくる際には、根切り部に基礎用の型枠を設置するとともにこの型枠にコンクリートスラリーを打設し、あるいは、PC製の基礎材を配置して建物の基礎を施工している。
【0003】
【発明が解決しようとする課題】
しかし、従来の地下室と基礎との施工方法では、地下室用の縦穴の埋め戻し作業を行なわなくてはならないため、縦穴と基礎の根切り部の施工を同時進行しても、縦穴と基礎の境界部においては、地下室用の縦穴の埋め戻し作業を行なってから基礎を設けなくてはならず、施工期間が長くなるという問題があった。
【0004】
本発明の目的は、地下室と基礎との施工期間の短縮化が図れるようになるプレキャストコンクリート連結部材を提供することにある。
【0005】
【課題を解決するための手段】
本発明に係るPC連結部材は、地下室の擁壁と建物の基礎とを連結するプレキャストコンクリート製の連結部材であって、前記建物の基礎に連結される一端面の高さ寸法が当該基礎の高さ寸法と略同一とされ、前記地下室の擁壁に連結される他端面の高さ寸法が当該擁壁の高さ寸法と略同一とされ、下面の少なくとも一部が前記基礎側から前記地下室の擁壁側に下り勾配に傾斜した傾斜部とされ、この傾斜部が前記地下室の施工時における縦穴の斜面に対応した傾斜角度を有して形成されていることを特徴とするものである。
【0006】
このPC連結部材において、長手方向の両端部に、上下方向に延びて側方に開口した断面略コ字状のコンクリート充填部を形成してもよい。また、本発明において、地下室の擁壁側の水平な下面に他端面および傾斜部の下端同士を結ぶ水平部を形成し、この水平部に下方に延びる鉄筋部材を設けてもよい。
【0007】
【作用】
このような本発明では、PC連結部材を、その下面の傾斜部が地下室の縦穴の斜面に沿うように配置できるため、地下室の擁壁と基礎との間で、縦穴の埋め戻し作業を行わなくてもよくなり、その分の手間を省略でき、これにより、地下室と基礎との施工期間の短縮化が図れるようになる。
【0008】
本発明において、PC連結部材の長手方向の両端部にコンクリート充填部を形成した場合には、地下室の擁壁および基礎とにPC連結部材の両端部を当接した後、コンクリート充填部内にコンクリートスラリーを打設すれば、このスラリーがコンクリート充填部を通じて地下室の擁壁および基礎に絡み付いた状態で固化し、これにより、PC連結部材で地下室の擁壁および基礎とを容易かつ強固に結合できる。
【0009】
また、本発明において、地下室の擁壁側の水平な下面に下方に伸びる鉄筋部材を設けた場合には、PC連結部材を設置するとき、鉄筋部材を地下室用の縦穴の底部に配置した鉄筋と結合させることができるので、PC連結部材を安定した状態で固定できる。
【0010】
【実施例】
以下に本発明の一実施例を図面に基づいて説明する。
図1,2には、地下室2を備えた建物1が示され、この建物1の地下室2と基礎3とは、本実施例に係るPC連結板4で連結されている。このような地下室2の擁壁も基礎3を構成する基礎材も、本実施例ではPC製となっている。
【0011】
基礎3は、複数のPC基礎材20を建物1の間取り形状に対応させて形成されている。このPC基礎材20の両端部20Aは断面コ字状となっており、その内部がコンクリート充填部20Sとなっている。このようなPC基礎材20の両端下部は、根切り部の底に配置したPCレベル調整板23の上に載せられるようになっている。また、PC基礎材20の下部にはフーチン部20Cが形成され、側面には人通孔20Bが明けられている。
なお、図1では、PC基礎材20の大きさ等は異なっているが、それぞれの構造等はまったく同じなので符号は同一としてある。
【0012】
地下室2の擁壁として使用されるPC壁部材10〜14は、側面ほぼ長方形状に形成され、その両端部10A〜14Aは断面コ字状となっており、その内部はコンクリート充填部10S〜14Sとなっている。但し、PC壁部材12の一端部およびPC壁部材13の両端部にはコンクリート充填部が形成されていない。また、PC壁部材10〜14の側面には角形の人通孔10B〜14Bが明けられ、作業者はこの人通孔10B〜14Bから出入りできるようになっている。
【0013】
これらのPC壁部材10〜14の下面には、図示しないが複数本の鉄筋部材が埋設され、その先端は下方に突出している。これらの鉄筋部材は、地下室用の縦穴15にPC壁部材10を設置するとき折り曲げられており、かつ、縦穴15の底部に配置された多数の鉄筋16と結合されるようになっている。なお、PC壁部材10は縦穴15の底部に配置されたPCレベル調整板17の上に載せられるようになっている。
【0014】
前記PC連結板4は、図3にも示すように、上面40が直線状となっており、下面41は、一端面4Aの高さ寸法で所定寸法水平に延びた第1の下面41Aと、一端面4Aより高い他端面4Bの高さ寸法で所定寸法水平に延びた第2の下面41Bと、長手方向の途中においてこれらの第1,2の下面41A,41Bとを結ぶ傾斜部41Cとで形成され、PC連結板4全体形状はいわゆるハンチ状となっている。
【0015】
ここで、PC連結板4の一端面4Aの高さ寸法は前記基礎3の高さ寸法とほぼ同じで、他端面4Bの高さ寸法は前記擁壁としてのPC壁部材10〜13の高さ寸法とほぼ同じとなっている。そして、第1の下面41Aの先端は基礎3の前記レベル調整板23上に載せられ、第2の下面41Bの先端は地下室2のレベル調整板17に上に載せられるようになっている。
【0016】
このようなPC連結板4の長手方向両端部4Dは断面コ字状となっており、その内部はコンクリート充填部4Sとなっている。このコンクリート充填部4S内には、図3に示すように、例えば鉄筋30を梯子状に組んだ枠部材31が挿入されるようになっている。従って、このコンクリート充填部4S内に枠部材31を挿入した後、コンクリートスラリーを打設すれば、スラリーが枠部材31にも絡み付くため、スラリーの固化によって、PC連結板4と例えばPC壁部材10等との結合が強固となる。
なお、前記PC基礎材20、PC壁部材10〜14におけるコンクリート充填部20S、10S等の内部にも上記枠部材31と同様の枠部材が挿入されるようになっている。
【0017】
また、PC連結板4の側面には人通孔4Eが明けられている。
さらに、PC連結板4の前記他端部側4Bの下面には例えば2本の鉄筋部材42が埋設され、その先端は下方に伸びている。これらの鉄筋部材42は、PC連結板4を設置するとき折り曲げられ、かつ、図4に示すように地下室2用の縦穴15の底部に配置した鉄筋16と結合されるようになっている。
【0018】
このようなPC連結部材4の取り付けは次のように行われる。
すなわち、基礎3においては、根切り部21の底部に適宜捨てコンを打設し、その後、PC基礎材20のフーチン部20Cを捨てコンの上に載せるとともに、両端部をPCレベル板23の上に設置し、PC基礎材20と根切り部21の埋め戻し部22に土を入れ、埋め戻し作業を行う。
【0019】
基礎3の施工完了後に、PC連結板4をその一端面4Aを基礎3の所定位置のPC基礎材20に当接させるとともに、下面41の傾斜部41Cを縦穴15の斜面に沿わせて配置する。このとき、PC連結板4の鉄筋部材42を折り曲げ、かつ、縦穴15の底部の鉄筋16と絡ませるとともに結合させ、PC連結板4を固定する。
【0020】
次いで、縦穴15の底部のPCレベル板17上に、PC壁部材10〜14を設置する。このとき、基礎3側に位置するPC壁部材10をPC連結板4の他端面4Bと当接させるとともに、各PC壁部材10〜14の下面に伸びた鉄筋部材を折り曲げ、縦穴15の鉄筋16に絡ませて結合させる。
【0021】
この後、地下室2とPC壁部材10との間に配置されているPC連結板4のコンクリート充填部4S内に枠部材31を挿入するとともに、コンクリートスラリーを打設する。一方で、地下室2の縦穴15において、PCレベル板17から所定寸法厚さとなるようにコンクリートスラリーを打設し、地下室2の床面2Aを形成する。また、PC連結板4の傾斜部4Cの下部にもコンクリートスラリーを打設し、このスラリーでPC連結板4の傾斜部41Cのフーチン部18を形成する。
次いで、縦穴15の埋め戻し部19に土を入れ埋め戻し作業を行う。ただし、地下室2と基礎3との間の埋め戻し部19’には土を入れず、そのままの状態としておく。
【0022】
そして、このような基礎3の上に、例えばパネル工法による地上建物6を載せ、地下室2の上にも同様の地上建物7を載せ、これにより、前記地下室付き建物1を建てる。
なお、地下室2は図示しない階段等で地上建物7等と出入りできるようにして例えば居室等として使用してもよく、あるいは地上からスロープを形成して地下室2に行けるようにして車庫等に利用してもよい。
【0023】
前述のような本実施例によれば次のような効果がある。
すなわち、PC連結板4には傾斜部41Cが形成されており、この傾斜部41Cを地下室2用の縦穴15の斜面に沿わせて配置できるので、縦穴15はそのままでよく、言い換えれば、地下室2と基礎3との間の縦穴15での埋め戻し作業は行わなくてもよくなり、その分の手間を省略できるため、工期の短縮化が図れるようになる。
【0024】
また、PC連結板4の傾斜部41Cの下方には、現場でコンクリートスラリーが打設され、このコンクリートスラリーの部分がPC連結板4のフーチン部18となるので、PC連結板4の安定性が増す。
【0025】
さらに、PC連結板4の両端部4Dには、コンクリート充填部4Sが形成されており、両端部4DをPC壁部材10とPC基礎材20と当接させた後、コンクリート充填部4S内にコンクリートスラリーを打設すれば、スラリーが両部材に絡み付いた状態で固化するため、PC連結板4でPC壁部材10とPC基礎材20とを容易に結合することができる。その上、コンクリート充填部4S内には、枠部材31が挿入されるため、コンクリートスラリーが枠部材31にも絡み付き、これにより、PC連結板4とPC壁部材10およびPC基礎材20との結合がより強固となる。
【0026】
また、PC連結板4には人通孔4Eが形成されているので、作業者はこの人通孔4Eから入ることができ、これにより、地下室2と基礎3との間でも作業が可能となる。
【0027】
なお、本発明は前述の実施例に限定されるものではなく、本発明の目的を達成できる範囲であれば次に示すような変形例を含むものである。
例えば、前記実施例では、PC連結板4はPC基礎材20で構成された基礎3とPC壁部材10〜14からなる擁壁で構成された地下室2を連結するものであったが、これに限らず、現場施工の基礎と現場施工の擁壁とを連結する場合にも利用できるものである。
【0028】
また、前記実施例では、基礎3を形成した後でPC連結板4を基礎3の所定のPC基礎材20と当接させ、このPC連結板4と当接させてPC壁部材10〜14を設置していたが、これらの部材の設置の順序はこれに限らず、例えばPC壁部材10〜14を設置した後でPC連結板4を配置し、次いでPC基礎材20を設置して基礎3を形成してもよく、あるいは、PC基礎材20とPC壁部材10〜14とを設置した後、PC連結板4を嵌め込むようにして設けてもよい。
【0029】
【発明の効果】
以上で説明したように、本発明によれば、PC連結部材を、その下面の傾斜部が地下室の縦穴の斜面に沿うように配置できるため、地下室の擁壁と基礎との間で、縦穴の埋め戻し作業を行わなくてもよくなり、その分の手間を省略でき、これにより、地下室と基礎との施工期間の短縮化が図れるようになる。
【0030】
また、PC連結部材の長手方向の両端部にコンクリート充填部が形成されているので、地下室の擁壁および基礎とにPC連結部材の両端部を当接した後、コンクリート充填部内にコンクリートスラリーを打設すれば、このスラリーがコンクリート充填部を通じて地下室の擁壁および基礎に絡み付いた状態で固化し、これにより、PC連結部材で地下室の擁壁および基礎とを容易かつ強固に結合できる。

[Industrial applications]
The present invention relates to a precast concrete connecting member, and can be used when connecting a retaining wall of a basement to a foundation of a building.
[0002]
[Background Art]
Buildings with basements are increasing due to demands such as realization of a new living system.
When building the basement of this building, a vertical hole for the basement is excavated and precast concrete (hereinafter referred to as PC) manufactured there by, for example, on-site construction or by casting concrete slurry into a formwork in advance at a factory. A retaining wall is provided to form the exterior of the basement, and then soil is put into vertical holes around the retaining wall for backfilling.
Also, when building the foundation of a building, install a foundation formwork at the root cutting part and cast concrete slurry into this formwork, or place a PC base material to lay the foundation of the building. Has been constructed.
[0003]
[Problems to be solved by the invention]
However, in the conventional method of constructing the basement and the foundation, it is necessary to refill the vertical hole for the basement. In the part, there was a problem that the foundation had to be provided after the backfill work of the vertical hole for the basement was performed, and the construction period was prolonged.
[0004]
An object of the present invention is to provide a precast concrete connecting member capable of shortening the construction period between a basement and a foundation.
[0005]
[Means for Solving the Problems]
The PC connecting member according to the present invention is a connecting member made of precast concrete for connecting a retaining wall of a basement to a foundation of a building, and a height dimension of one end face connected to the foundation of the building is a height of the foundation. The height dimension of the other end face connected to the retaining wall of the basement is substantially the same as the height dimension of the retaining wall, and at least a part of the lower surface is at least partially An inclined portion inclined downwardly toward the retaining wall is formed, and the inclined portion is formed to have an inclination angle corresponding to the inclined surface of the vertical hole when the basement is constructed .
[0006]
In this PC connecting member, a concrete filling portion extending in the up-down direction and having a substantially U-shaped cross section may be formed at both ends in the longitudinal direction. Further, in the present invention, a horizontal portion connecting the other end surface and the lower end of the inclined portion may be formed on the horizontal lower surface on the retaining wall side of the basement, and a rebar member extending downward may be provided on the horizontal portion .
[0007]
[Action]
In the present invention, since the PC connecting member can be arranged so that the inclined portion of the lower surface is along the slope of the vertical hole of the basement, the work of backfilling the vertical hole is not performed between the retaining wall of the basement and the foundation. It is possible to shorten the construction period between the basement and the foundation, thereby reducing the time required for the work.
[0008]
In the present invention, in the case where concrete filling portions are formed at both ends in the longitudinal direction of the PC connecting member, after the both ends of the PC connecting member abut against the retaining wall and the foundation of the basement, the concrete slurry enters the concrete filling portion. When this is cast, the slurry is solidified in a state of being entangled with the retaining wall and the foundation of the basement through the concrete filling portion, whereby the PC connecting member can easily and firmly connect the retaining wall and the foundation of the basement.
[0009]
Further, in the present invention, when a reinforcing member extending downward is provided on the horizontal lower surface on the retaining wall side of the basement, when the PC connecting member is installed, the reinforcing member is disposed at the bottom of the vertical hole for the basement. Since the connection can be performed, the PC connecting member can be fixed in a stable state.
[0010]
【Example】
An embodiment of the present invention will be described below with reference to the drawings.

In this embodiment, both the retaining wall of the basement 2 and the base material constituting the base 3 are made of PC.
[0011]
The foundation 3 is formed so that a plurality of PC foundation materials 20 correspond to the floor plan of the building 1. Both ends 20A of the PC base material 20 have a U-shaped cross section, and the inside thereof is a concrete filling portion 20S. The lower ends of both ends of the PC base material 20 are placed on a PC level adjustment plate 23 arranged at the bottom of the root cutting portion. Further, a footing portion 20C is formed at a lower portion of the PC base material 20, and a through hole 20B is opened at a side surface.
In FIG. 1, although the size and the like of the PC base material 20 are different, since the respective structures and the like are completely the same, the reference numerals are the same.
[0012]
The PC wall members 10 to 14 used as retaining walls of the basement 2 are formed in a substantially rectangular side surface, and both end portions 10A to 14A have a U-shaped cross section, and the inside thereof has a concrete filling portion 10S to 14S. It has become. However, concrete filling portions are not formed at one end of the PC wall member 12 and at both ends of the PC wall member 13. In addition, rectangular human through holes 10B to 14B are formed in side surfaces of the PC wall members 10 to 14, so that an operator can enter and exit through the human through holes 10B to 14B.
[0013]
Although not shown, a plurality of reinforcing members (not shown) are embedded in the lower surfaces of the PC wall members 10 to 14, and the tips protrude downward. These reinforcing members are bent when the PC wall member 10 is installed in the vertical hole 15 for the basement, and are connected to a large number of reinforcing bars 16 arranged at the bottom of the vertical hole 15. Note that the PC wall member 10 is mounted on a PC level adjustment plate 17 disposed at the bottom of the vertical hole 15.
[0014]
As shown in FIG. 3, the PC connection plate 4 has an upper surface 40 formed in a straight line, and a lower surface 41 having a first lower surface 41A extending horizontally by a predetermined dimension at the height of one end surface 4A. A second lower surface 41B extending horizontally by a predetermined dimension at the height of the other end surface 4B higher than the one end surface 4A, and an inclined portion 41C connecting the first and second lower surfaces 41A and 41B in the middle of the longitudinal direction. The entire shape of the PC connecting plate 4 is so-called haunched.
[0015]
Here, the height dimension of one end face 4A of the PC connecting plate 4 is substantially the same as the height dimension of the base 3, and the height dimension of the other end face 4B is the height of the PC wall members 10 to 13 as the retaining wall. The dimensions are almost the same. The tip of the first lower surface 41A is placed on the level adjusting plate 23 of the foundation 3, and the tip of the second lower surface 41B is placed on the level adjusting plate 17 of the basement 2.
[0016]
Both ends 4D in the longitudinal direction of such a PC connecting plate 4 have a U-shaped cross section, and the inside thereof is a concrete filling portion 4S. As shown in FIG. 3, for example, a frame member 31 in which reinforcing bars 30 are assembled in a ladder shape is inserted into the concrete filling portion 4S. Therefore, if the concrete slurry is cast after the frame member 31 is inserted into the concrete filling portion 4S, the slurry also becomes entangled with the frame member 31, so that the solidification of the slurry causes the PC connecting plate 4 and the PC wall member 10 And the like.
A frame member similar to the frame member 31 is inserted into the concrete bases 20 and the concrete filling portions 20S and 10S of the PC wall members 10 to 14.

In addition, a through hole 4E is formed in a side surface of the PC connecting plate 4.
Further, for example, two rebar members 42 are buried in the lower surface of the other end 4B of the PC connecting plate 4, and the front ends thereof extend downward. These rebar members 42 are bent when the PC connection plate 4 is installed, and are coupled to the rebar 16 arranged at the bottom of the vertical hole 15 for the basement 2 as shown in FIG.
[0018]
The attachment of the PC connecting member 4 is performed as follows.
That is, in the foundation 3, a discarding concrete is appropriately placed on the bottom of the root cutting portion 21, and then the footing portion 20 </ b> C of the PC base material 20 is placed on the discarding concrete, and both ends are placed on the PC level plate 23. The soil is put into the backfilling part 22 of the PC base material 20 and the root cutting part 21 to perform the backfilling work.
[0019]
After completion of the construction of the foundation 3, the PC connecting plate 4 is arranged such that one end surface 4A thereof is in contact with the PC foundation material 20 at a predetermined position of the foundation 3, and the inclined portion 41C of the lower surface 41 is arranged along the inclined surface of the vertical hole 15. . At this time, the reinforcing bar member 42 of the PC connecting plate 4 is bent and entangled with the reinforcing bar 16 at the bottom of the vertical hole 15 so as to be connected thereto, thereby fixing the PC connecting plate 4.
[0020]
Next, the PC wall members 10 to 14 are installed on the PC level plate 17 at the bottom of the vertical hole 15. At this time, the PC wall member 10 located on the side of the base 3 is brought into contact with the other end surface 4B of the PC connecting plate 4, and the reinforcing member extending to the lower surface of each of the PC wall members 10 to 14 is bent to form the reinforcing bar 16 of the vertical hole 15.

Thereafter, the frame member 31 is inserted into the concrete filling portion 4S of the PC connecting plate 4 disposed between the basement 2 and the PC wall member 10, and concrete slurry is poured. On the other hand, concrete slurry is poured into the vertical hole 15 of the basement 2 from the PC level plate 17 so as to have a predetermined thickness, thereby forming the floor surface 2A of the basement 2. Also, concrete slurry is poured into a lower portion of the inclined portion 4C of the PC connecting plate 4 and the footing portion 18 of the inclined portion 41C of the PC connecting plate 4 is formed with the slurry.
Next, soil is put into the backfilling portion 19 of the vertical hole 15 to perform backfilling work. However, the soil is not put into the backfilling portion 19 'between the basement 2 and the foundation 3, and is left as it is.
[0022]
Then, on such a foundation 3, a ground building 6 by, for example, the panel method is mounted, and a similar ground building 7 is also mounted on the basement 2, whereby the building 1 with a basement is built.
The basement 2 may be used as, for example, a living room or the like by allowing access to the building 7 or the like by stairs or the like (not shown), or may be used as a garage by forming a slope from the ground so that the basement 2 can be accessed. May be.
[0023]
According to the above-described embodiment, the following effects can be obtained.
That is, the PC connecting plate 4 is formed with the inclined portion 41C, and the inclined portion 41C can be arranged along the slope of the vertical hole 15 for the basement 2, so that the vertical hole 15 can be left as it is, in other words, the basement 2 The backfill work in the vertical hole 15 between the base 3 and the base 3 does not need to be performed, and the labor for the backfill can be omitted, so that the construction period can be shortened.
[0024]
In addition, concrete slurry is cast on the site below the inclined portion 41C of the PC connecting plate 4 and the portion of the concrete slurry becomes the footing portion 18 of the PC connecting plate 4, so that the stability of the PC connecting plate 4 is reduced. Increase.
[0025]
Further, concrete filling portions 4S are formed at both end portions 4D of the PC connecting plate 4. After the both end portions 4D are brought into contact with the PC wall member 10 and the PC base material 20, concrete is filled in the concrete filling portion 4S. When the slurry is cast, the slurry is solidified while being entangled with both members, so that the PC wall member 10 and the PC base material 20 can be easily connected by the PC connecting plate 4. In addition, since the frame member 31 is inserted into the concrete filling portion 4S, the concrete slurry is also entangled with the frame member 31, thereby connecting the PC connecting plate 4 with the PC wall member 10 and the PC base material 20. Becomes more robust.
[0026]
In addition, since the PC connection plate 4 has the human through hole 4E formed therein, the worker can enter through the human through hole 4E, whereby the work can be performed between the basement 2 and the foundation 3. .
[0027]
The present invention is not limited to the above-described embodiment, but includes the following modified examples as long as the object of the present invention can be achieved.

【The invention's effect】
As described above, according to the present invention, the PC connecting member can be arranged so that the inclined portion on the lower surface thereof is along the slope of the vertical hole in the basement. It is not necessary to perform the backfilling work, and the trouble can be saved, thereby shortening the construction period between the basement and the foundation.
[0030]
In addition, since concrete filling portions are formed at both ends in the longitudinal direction of the PC connecting member, after the both ends of the PC connecting member abut against the retaining wall and the foundation of the basement, concrete slurry is poured into the concrete filling portion. If provided, the slurry solidifies in a state of being entangled with the retaining wall and the foundation of the basement through the concrete filling portion, whereby the PC connecting member can easily and firmly connect the retaining wall and the foundation of the basement with the PC connecting member.
