Description

本発明は、人通孔の形成方法、補強構造、補強方法、および人通孔金物に関し、特にコンクリート型枠にコンクリートを打設することで、耐力を備えた人通孔を基礎の立ち上がり壁部に形成する人通孔の形成方法、補強構造、補強方法、および人通孔金物に関する。 The present invention relates to a method for forming a passage hole, a reinforcing structure, a reinforcement method, and a passage hole hardware, and particularly by placing concrete in a concrete formwork, a passage hole having a bearing capacity is formed as a rising wall portion of the foundation. The present invention relates to a method of forming a passage hole, a reinforcing structure, a reinforcing method, and a passage hole metal fitting.

従来から、木造住宅は地面に近い床下部分から腐食や老朽化が進みやすく、地震や台風による倒壊被害を軽減するためにも、定期的な床下内部の点検が必要とされていた。床下の点検は通常、人が床下へ入り込んで床下の点検を行っている。 Traditionally, wooden houses are prone to corrosion and deterioration from the underfloor area near the ground, and regular inspections of the inside of the underfloor have been required to reduce the damage caused by collapses caused by earthquakes and typhoons. Underfloor inspections are usually carried out by people going under the floor to inspect the underfloor.

かつての木造住宅の和室の畳の下には、幅広のムク板が釘ドメされているだけであった。このため釘を外すだけで簡単に畳を取り外すことができるので、床下の点検には、畳を外すだけで、どこでも簡単に床下に入ることができる構造であった。 Under the tatami mats in the Japanese-style room of the old wooden house, only a wide muku board was nailed. For this reason, the tatami mats can be easily removed simply by removing the nails, so for underfloor inspections, the structure was such that the tatami mats could be easily removed anywhere.

近年では、和室の需要が減り、洋室の需要が増加している。これは日本人が床の上で座っての食事や、布団を敷いての就寝などの習慣が減り、日本人のライフスタイルが大きく変化しことによる影響が挙げられる。 In recent years, the demand for Japanese-style rooms has decreased, and the demand for Western-style rooms has increased. This is due to the fact that Japanese people have less habits such as eating while sitting on the floor and going to bed with futons, and the lifestyle of Japanese people has changed significantly.

このように、需要が増えている洋室では、床や廊下の表面にはフローリング材が利用されている。この敷設されたフローリング材を取り外して床下に人が入ろうとした場合、取り外したフローリングはが膨潤してしまうため、取り外したフローリング材を再利用することも難しい。 In this way, in Western-style rooms where demand is increasing, flooring materials are used on the floor and the surface of corridors. If a person tries to enter under the floor by removing the laid flooring material, the removed flooring will swell, and it is difficult to reuse the removed flooring material.

また床下の点検の都度、部分的にフローリング材を取り外し、その取り外した部分だけを張り替えても、フローリングの木目を合わせることが不可能であり、結局、床下の点検の度に、フローリング材を取り外して新しく張り替えるのは現実的ではない。 In addition, even if the flooring material is partially removed each time the underfloor inspection is performed and only the removed part is replaced, it is impossible to match the grain of the flooring. After all, the flooring material is removed every time the underfloor inspection is performed. It is not realistic to replace it with a new one.

一方で、増加傾向のある洋室には、床暖房機器を設置する住宅も増えている。このような床暖房機器を設置した洋室の床下には、温水式床暖房に必要な配管や電気式床暖房に必要な配線などが敷設されている。このような床暖房機器にも定期的なメンテナンスが必要であり、メンテナンス時には配管や配線が敷設された床下に人が入る必要がある。
ところが、床下には配管や配線があちこちに敷設されているため、洋室から床下に入るのは非常に困難を伴う。 On the other hand, in Western-style rooms, which are on the increase, the number of houses equipped with floor heating equipment is increasing. Under the floor of a Western-style room where such floor heating equipment is installed, piping required for hot water floor heating and wiring required for electric floor heating are laid. Regular maintenance is also required for such floor heating equipment, and it is necessary for people to enter under the floor where piping and wiring are laid during maintenance.
However, it is very difficult to get under the floor from a Western-style room because pipes and wiring are laid here and there under the floor.

そこで建物の下部構造である基礎の立ち上がり壁部に、あらかじめ人が通れる程度の人通孔を形成することで、床下の点検時など、容易に人が床下へ入れる構造が提案されている。しかし基礎の立ち上がり部に設けた人通孔による断面欠損により、構造的に弱体化してしまう。このため、鉄筋増強などの人通孔の周囲の補強は必至である。（たとえば、特許文献１、２参照）。 Therefore, a structure has been proposed in which a person can easily enter under the floor, such as when inspecting the underfloor, by forming a passage hole in the rising wall of the foundation, which is the lower structure of the building, in advance so that people can pass through. However, it is structurally weakened due to a cross-sectional defect due to a passage hole provided at the rising portion of the foundation. Therefore, it is inevitable to reinforce the circumference of the passage hole such as reinforcing the reinforcing bar. (See, for example, Patent Documents 1 and 2).

図１０は、鉄筋で人通孔の周囲を補強した従来の補強構造の一例を示す側面図である。
図１０に示すように、基礎の立ち上がり壁部１には、円形の人通孔２が形成されている。また人通孔２の周囲には、人通孔２の欠損を防止するための補強構造１０が形成されている。 FIG. 10 is a side view showing an example of a conventional reinforcing structure in which the periphery of the passage hole is reinforced with reinforcing bars.
As shown in FIG. 10, a circular passage hole 2 is formed in the rising wall portion 1 of the foundation. Further, a reinforcing structure 10 is formed around the passage hole 2 to prevent the passage hole 2 from being damaged.

補強構造１０は、人通孔２の左右縦方向にＸ字状に配筋された斜筋１１と、人通孔２を取り巻くように配筋された縦筋１２および横筋１３とが、人通孔２の上部および下部に配筋された主筋１４に緊結されている。 In the reinforcing structure 10, the diagonal bars 11 arranged in an X shape in the left-right vertical direction of the passage hole 2 and the vertical bars 12 and the horizontal bars 13 arranged so as to surround the passage hole 2 are arranged for communication. It is tied to the main bar 14 arranged in the upper part and the lower part of the hole 2.

図１１は、支柱枠で人通孔の周囲を補強した従来の補強構造の一例を示す側面図である。
図１１に示すように、基礎の立ち上がり壁部１には、円形の人通孔２が形成されている。また人通孔２の周囲には、人通孔２の欠損を防止するための補強構造２０が形成されている。 FIG. 11 is a side view showing an example of a conventional reinforcing structure in which the periphery of the passage hole is reinforced with a support frame.
As shown in FIG. 11, a circular passage hole 2 is formed in the rising wall portion 1 of the foundation. Further, a reinforcing structure 20 is formed around the passage hole 2 to prevent the passage hole 2 from being damaged.

補強構造２０は、人通孔２の左右縦方向にＸ字状に配置された平鋼からなる斜材２１と人通孔２の上部と下部に設置された山形鋼からなる横材２２とを備えている。この補強構造２０は、基礎立ち上がり壁部１の内部に埋設されることで、人通孔２の欠損を防止している。 The reinforcing structure 20 includes a diagonal member 21 made of flat steel arranged in an X shape in the left-right vertical direction of the passage hole 2 and a horizontal member 22 made of angle steel installed above and below the passage hole 2. I have. The reinforcing structure 20 is embedded inside the foundation rising wall portion 1 to prevent the passage hole 2 from being damaged.

図１１の補強構造２０は、図１０の鉄筋による人通孔の補強構造１０を、山形鋼や平鋼からなる支柱枠を人通孔２の周囲に配置することで、補強構造の剛性を強化したものである。しかし、これらの補強構造１０、２０では円形の人通孔２の周囲を鉄筋や支柱枠で補強しているため、人通孔２の大きさは必然と制限されてしまう。 In the reinforcing structure 20 of FIG. 11, the rigidity of the reinforcing structure is strengthened by arranging the reinforcing structure 10 of the passage hole by the reinforcing bar of FIG. 10 and the support frame made of angle steel or flat steel around the passage hole 2. It was done. However, in these reinforcing structures 10 and 20, since the periphery of the circular passage hole 2 is reinforced with reinforcing bars or support columns, the size of the passage hole 2 is inevitably limited.

このため図１０や図１１の人通孔２は円形となってしまい、人通孔２の上部および下部の横幅が狭くなってしまう。このため大きな基礎壁はともかく、円形の人通孔２は中小規模の基礎には不向きなことが多く、人が通りにくい形状となってしまっていた。
そこで人通孔２の大きさを必要十分に形成し、人が容易に通れるようにした人通孔が提案されている（たとえば、特許文献３参照）。 Therefore, the passage holes 2 in FIGS. 10 and 11 become circular, and the widths of the upper and lower portions of the passage holes 2 become narrower. For this reason, aside from the large foundation wall, the circular passage hole 2 is often unsuitable for small and medium-sized foundations, and has a shape that makes it difficult for people to pass through.
Therefore, a human passage hole has been proposed in which the size of the human passage hole 2 is formed to be necessary and sufficient so that a person can easily pass through the hole (see, for example, Patent Document 3).

図１２は、矩形の人通孔の周囲を補強した従来の補強構造を示す側面図である。
図１２に示すように、基礎の立ち上がり壁部１には、基礎の立ち上がり壁部１の上部が開放された矩形の人通孔３が形成されている。また人通孔３の周囲には、人通孔３の欠損を防止するための補強構造３０が形成されている。 FIG. 12 is a side view showing a conventional reinforcing structure in which the periphery of a rectangular passage hole is reinforced.
As shown in FIG. 12, the rising wall portion 1 of the foundation is formed with a rectangular communication hole 3 in which the upper portion of the rising wall portion 1 of the foundation is open. Further, a reinforcing structure 30 is formed around the passage hole 3 to prevent the passage hole 3 from being damaged.

補強構造３０は、人通孔３の上部に配筋される上端筋３１と、人通孔３の下部に配筋される腹筋３２および下端筋３３と、人通孔３の左右に配筋した斜筋３４と、上端筋３１、腹筋３２、下端筋３３、および斜筋３４を連結する肋筋３５とを備えている。 The reinforcing structure 30 has an upper end muscle 31 arranged in the upper part of the passage hole 3, an abdominal muscle 32 and a lower end muscle 33 arranged in the lower part of the passage hole 3, and reinforcements arranged on the left and right sides of the passage hole 3. It includes an oblique muscle 34, an upper end muscle 31, an abdominal muscle 32, a lower end muscle 33, and a rib muscle 35 connecting the oblique muscle 34.

このような補強構造３０により補強された矩形の人通孔３は、基礎立ち上がり壁部１の上部を開放するように形成することで、円形の人通孔２では狭くなっていた上部と下部の横幅が広くなり、人が通りやすい形状になっている。 The rectangular passage hole 3 reinforced by the reinforcing structure 30 is formed so as to open the upper portion of the foundation rising wall portion 1, so that the upper portion and the lower portion which are narrowed in the circular passage hole 2 are formed. The width is wide and the shape is easy for people to pass through.

このように人が通りやすいように基礎の立ち上がり壁部の上部を開放した矩形の人通孔３は、人通孔３の下部から隅部にかけて構造的な弱点となってしまうため、基礎立ち上がり壁部の長さ方向の一部を人通孔の幅だけカットして人通孔用の切り欠きを設け、その跡に形状寸法を合わせた軽量チャンネル製の枠組をセットし、アンカーボルト止めに固定した人通孔が提案されている（たとえば、特許文献４参照）。 In this way, the rectangular passage hole 3 in which the upper part of the rising wall of the foundation is opened so that people can easily pass through becomes a structural weakness from the lower part to the corner of the passage 3, so that the rising wall of the foundation A part in the length direction of the part is cut by the width of the passage hole to provide a notch for the passage hole, and a lightweight channel frame with matching shape and dimensions is set in the mark and fixed to the anchor bolt. Anchor holes have been proposed (see, for example, Patent Document 4).

図１３は、人通孔の周囲を補強した従来の補強構造の一例を示す側面図である。
図１３に示すように、基礎立ち上がり壁部１には人通孔４が設けられ、人通孔４の周囲に補強部材４０が取付けられている。 FIG. 13 is a side view showing an example of a conventional reinforcing structure in which the periphery of the passage hole is reinforced.
As shown in FIG. 13, a passage hole 4 is provided in the foundation rising wall portion 1, and a reinforcing member 40 is attached around the passage hole 4.

補強部材４０は、基礎立ち上がり壁部１に形成される人通孔４の両側に各々取り付けられる一対の側枠部材４１と、その一対の側枠部材４１の上部間に配置される上枠部材４２と、一対の側枠部材４１の下部間に配置される下枠部材４３と、一対の側枠部材４１に対し上枠部材４２及び下枠部材４３を各々位置調整可能にそれぞれ連結する連結部材とを備えている。 The reinforcing member 40 is a pair of side frame members 41 attached to both sides of a passage hole 4 formed in the foundation rising wall portion 1, and an upper frame member 42 arranged between the upper portions of the pair of side frame members 41. And a lower frame member 43 arranged between the lower parts of the pair of side frame members 41, and a connecting member for connecting the upper frame member 42 and the lower frame member 43 to the pair of side frame members 41 so that their positions can be adjusted. It has.

具体的には、連結部材は、側枠部材４１と上枠部材４２または下枠部材４３に少なくとも長孔４５を介して各々位置調整可能に重ねられる連結プレート４４と、側枠部材４１と上枠部材４２または下枠部材４３を長孔４５に各々通してそれぞれ固定するボルト４６及びナット４７とからなる。 Specifically, the connecting members include a connecting plate 44 which is vertically adjustable on the side frame member 41 and the upper frame member 42 or the lower frame member 43 via at least an elongated hole 45, and the side frame member 41 and the upper frame. It is composed of bolts 46 and nuts 47 for fixing the member 42 or the lower frame member 43 through the elongated holes 45, respectively.

しかし、この補強部材４０による人通孔補強構造によると、側枠部材４１の幅方向が調節可能とは言え、固定したときに基礎立ち上がり壁部１との間に隙間が生じるため、基礎立ち上がり壁部１と緊密に固定することが難しく、構造的に布基礎が連続して構築され難い問題があった。 However, according to the passage hole reinforcement structure by the reinforcing member 40, although the width direction of the side frame member 41 can be adjusted, a gap is generated between the side frame member 41 and the foundation rising wall portion 1 when the side frame member 41 is fixed. There is a problem that it is difficult to fix the cloth foundation tightly to the part 1 and it is structurally difficult to construct the cloth foundation continuously.

本発明はこのような点に鑑みてなされたものであり、住宅基礎の立ち上がり壁部に人が通り抜けることのできる必要十分な大きさを有し、かつ強度と施工のし易さを備えた人通孔を形成可能な人通孔の形成方法、補強構造、補強方法、および人通孔金物を提供することを目的とする。 The present invention has been made in view of these points, and is a person having a necessary and sufficient size for a person to pass through the rising wall of a housing foundation, and having strength and ease of construction.

以下、本発明の実施の形態を、図面を参照して詳細に説明する。
〔第１の実施の形態〕
図１は、第１の実施の形態に係る人通孔金物が人通孔を形成した後の状態を示す全体斜視図である。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[First Embodiment]
FIG. 1 is an overall perspective view showing a state after the passage hole hardware according to the first embodiment forms a passage hole.

図１に示すように、人通孔金物１００は、住宅基礎２００を形成する場合に、その住宅基礎２００の基礎立ち上がり壁部２１０に人通孔３００を形成するための装置である。また住宅基礎２００が形成された後に、人通孔金物１００は住宅基礎２００に埋設されたまま、人通孔３００の補強を担うための装置である。 As shown in FIG. 1, the passage hole hardware 100 is a device for forming a passage hole 300 in the foundation rising wall portion 210 of the housing foundation 200 when the housing foundation 200 is formed. Further, after the housing foundation 200 is formed, the communication hole hardware 100 is a device for reinforcing the communication hole 300 while being buried in the housing foundation 200.

人通孔金物１００は、枠体１１０および台形梁１２０で構成された枠型函体である。
枠体１１０は、短辺方向断面において上辺部が開放された「コの字」状に金属製の板材が接合された矩形状の枠体である。また枠体１１０は、住宅基礎２００の長手方向に沿って、枠体１１０の開放された開口部を上面にして、立ち上がり部壁部２１０に埋設されている。 The communication hole metal fitting 100 is a frame-type box body composed of a frame body 110 and a trapezoidal beam 120.
The frame 110 is a rectangular frame in which metal plates are joined in a “U” shape with an open upper side in a cross section in the short side direction. Further, the frame body 110 is embedded in the rising portion wall portion 210 along the longitudinal direction of the housing foundation 200 with the open opening of the frame body 110 as the upper surface.

枠体１１０は、２枚の側面板１１１と底面板１１２とを備えている。
側面板１１１は、形成される住宅基礎２００の基礎立ち上がり壁部２１０の厚さと同じ幅と、基礎立ち上がり壁部２１０に形成される人通孔３００の高さと同じ高さとで構成された金属製の板材である。 The frame body 110 includes two side plate 111 and a bottom plate 112.
The side plate 111 is made of metal and has the same width as the thickness of the foundation rising wall portion 210 of the housing foundation 200 to be formed and the same height as the height of the passage hole 300 formed in the foundation rising wall portion 210. It is a plate material.

材質は溶融亜鉛メッキ鋼板、ステンレス鋼板、樹脂コーティング金属板などの耐食性の強い金属を使用することで早期劣化などを防止することができる。枠体１１０を構成する２枚の側面板１１１は、基礎立ち上がり壁部２１０の長さ方向に対向するように、基礎立ち上がり壁部２１０の高さ方向に沿って設けられる。 Premature deterioration can be prevented by using a metal having strong corrosion resistance such as a hot-dip galvanized steel sheet, a stainless steel sheet, or a resin-coated metal plate. The two side plate 111s constituting the frame body 110 are provided along the height direction of the foundation rising wall portion 210 so as to face each other in the length direction of the foundation rising wall portion 210.

底面板１１２は、形成される住宅基礎２００の基礎立ち上がり壁部２１０の厚さと同じ幅と、基礎立ち上がり壁部２１０に形成される人通孔３００の幅と同じ長さとで構成された金属製の板材である。材質は側面板１１１と同様に溶融亜鉛メッキ鋼板などの耐食性の強い金属を使用することが望ましい。 The bottom plate 112 is made of metal and has the same width as the thickness of the foundation rising wall portion 210 of the housing foundation 200 to be formed and the same length as the width of the passage hole 300 formed in the foundation rising wall portion 210. It is a plate material. As the material, it is desirable to use a metal having strong corrosion resistance such as a hot-dip galvanized steel plate as in the side plate 111.

底面板１１２は基礎立ち上がり壁部２１０の長手方向に向けて水平に設置され、底面板１１２の短辺方向の両端部には、２枚の側面板１１１が垂直に固定される。これにより枠体１１０は、２枚の側面板１１１と底面板１１２とが短辺方向断面において上辺部が開放された「コの字」状に接合される。 The bottom plate 112 is installed horizontally toward the longitudinal direction of the foundation rising wall portion 210, and two side plate 111s are vertically fixed to both ends of the bottom plate 112 in the short side direction. As a result, in the frame 110, the two side plates 111 and the bottom plate 112 are joined in a "U" shape with the upper side open in the short side cross section.

台形梁１２０は、梁材として上面板１２１と２枚の台形フランジ板１２２とを備えている。
上面板１２１は、底面板１１２と同様に形成される住宅基礎２００の基礎立ち上がり壁部２１０の厚さと同じ幅と、基礎立ち上がり壁部２１０に形成される人通孔３００の幅と同じ長さとで構成された金属製のフランジ板材である。この上面板１２１は、短辺方向断面において上辺部が開放され「コの字」状に形成された枠体１１０の開口部を塞ぐように枠体１１０の天頂部に固定される。 The trapezoidal beam 120 includes a top plate 121 and two trapezoidal flange plates 122 as beam materials.
The top plate 121 has the same width as the thickness of the foundation rising wall portion 210 of the housing foundation 200 formed in the same manner as the bottom plate 112, and the same length as the width of the communication hole 300 formed in the foundation rising wall portion 210. It is a constructed metal flange plate material. The upper surface plate 121 is fixed to the zenith of the frame 110 so as to close the opening of the frame 110 formed in a "U" shape with the upper side open in the cross section in the short side direction.

台形フランジ板１２２は短辺方向断面が「コの字」状の形状をした板材である。この台形フランジ板１２２は、側面視で住宅基礎２００の長手方向に沿って、上面板１２１の長手方向の両側面に垂直方向に固定される。固定位置は、台形フランジ板１２２の側面視の長手方向両端部に近い台形ハンチが、上面板１２１と側面板１１１との接合部にかかるように、かつ台形フランジ板１２２の中央部底辺が、上面板１２１の底面と高さ方向が同等位置になるように取付けられ、長手方向側面視で台形アーチ状に構成される。 The trapezoidal flange plate 122 is a plate material having a "U-shaped" cross section in the short side direction. The trapezoidal flange plate 122 is vertically fixed to both side surfaces of the upper surface plate 121 in the longitudinal direction along the longitudinal direction of the housing foundation 200 in a side view. The fixed position is such that the trapezoidal haunch near both ends of the trapezoidal flange plate 122 in the longitudinal direction is applied to the joint between the top plate 121 and the side plate 111, and the bottom of the central portion of the trapezoidal flange plate 122 is on the top. The face plate 121 is attached so that the bottom surface and the height direction are at the same position, and is formed in a trapezoidal arch shape in the longitudinal side view.

これにより台形梁１２０は、単なる水平に繋いだ水平梁よりも断面係数が増加する。そのうえ、アーチ効果による変形減少も期待できる。また短辺方向断面も溝形に形成されるので、曲げ強度が増加する。なお、台形梁１２０の材質は枠体１１０と同質同効のものである。 As a result, the trapezoidal beam 120 has an increased moment of inertia of area as compared with a mere horizontally connected horizontal beam. In addition, it can be expected to reduce deformation due to the arch effect. Further, since the cross section in the short side direction is also formed in a groove shape, the bending strength is increased. The material of the trapezoidal beam 120 is the same as that of the frame 110.

以上のように構成された人通孔金物１００は、住宅基礎２００のコンクリート型枠組み立て時に、コンクリート型枠内の所定の位置に正確に設置または固定され、周囲の補強鉄筋に結束、または点溶接で接続されたうえ、そのままコンクリート打設時に埋め込まれる。なお、人通孔３００の開口面の周囲に、あらかじめ防水シールを施しておいてもよい。 The communication hole hardware 100 configured as described above is accurately installed or fixed at a predetermined position in the concrete formwork when the concrete formwork of the housing foundation 200 is assembled, and is bound or spot welded to the surrounding reinforcing reinforcing bars. After being connected with, it will be embedded as it is when placing concrete. A waterproof seal may be provided in advance around the opening surface of the passage hole 300.

脱型の後、形成された基礎立ち上がり壁部２１０に埋め込まれ一体化された人通孔金物１００は、２枚の側面板１１１、底面板１１２、上面板１２１が打設されたコンクリートと密着して人通孔３００の内側面を補強するので、耐久強度のある人通孔３００を形成することができる。 After the demolding, the through-hole metal fitting 100 embedded and integrated in the formed foundation rising wall portion 210 is in close contact with the concrete in which the two side plate 111, the bottom plate 112, and the top plate 121 are placed. Since the inner surface of the passage hole 300 is reinforced, the passage hole 300 having a durable strength can be formed.

このように形成された人通孔３００は、住宅基礎２００の長手方向に作用する応力を金属製の人通孔金物１００で負担し、基礎立ち上がり部壁部２１０上に固定される構造物の住宅土台４００が載荷された際にも、人通孔３００による空間部に起因する上部応力によって生じる住宅基礎２００の損傷を防止、抑制することができる。 The passage hole 300 formed in this way bears the stress acting in the longitudinal direction of the housing foundation 200 by the metal passage hole metal fitting 100, and is fixed on the wall portion 210 of the rising portion of the foundation. Even when the base 400 is loaded, it is possible to prevent and suppress damage to the housing foundation 200 caused by the upper stress caused by the space portion due to the passage hole 300.

基礎立ち上がり壁部２１０に、将来設置される住宅土台４００は、基礎立ち上がり壁部２１０の長手方向上部に沿って設置される。人通孔金物１００の上部には、住宅土台４００が対向した２枚の台形フランジ板１２２で形成された台形梁１２０の溝に、はめ込まれて設定される。 The housing base 400 to be installed on the foundation rising wall portion 210 in the future is installed along the upper part in the longitudinal direction of the foundation rising wall portion 210. The upper part of the communication hole hardware 100 is set by being fitted into a groove of a trapezoidal beam 120 formed by two trapezoidal flange plates 122 facing each other with a housing base 400.

また住宅土台４００は、住宅土台４００に設けたアンカーボルト孔４１０と、アンカーボルト１３１の位置に合わせて上面板１２１に穿孔されたボルト孔１２３とが合わせられ、アンカーボルト１３１によって結合される。 Further, in the housing base 400, the anchor bolt holes 410 provided in the housing base 400 and the bolt holes 123 drilled in the upper surface plate 121 according to the positions of the anchor bolts 131 are aligned and connected by the anchor bolts 131.

これにより、住宅土台４００と住宅基礎２００に固定された人通孔金物１００とが一体化されるため、住宅土台４００にかかる上部構造物に起因する応力を、住宅基礎２００と住宅基礎２００とに固定された人通孔金物１００とで支えることができる。結果、人通孔３００に過度な負担がかかることがなく、人通孔３００の欠損を防止することができる。 As a result, the housing foundation 400 and the communication hole hardware 100 fixed to the housing foundation 200 are integrated, so that the stress caused by the superstructure applied to the housing foundation 400 is applied to the housing foundation 200 and the housing foundation 200. It can be supported by a fixed through-hole hardware 100. As a result, the passage hole 300 is not overloaded, and the passage hole 300 can be prevented from being damaged.

このように形成された人通孔３００によって、基礎立ち上がり壁部２１０の上部を開放した形状としても人通孔３００を必要十分な大きさに保つことが可能になる。さらに開放した人通孔３００の上辺部を台形梁１２０で強化したことで、アーチ効果により構造的変形が抑えられ、人通孔３００の大きさを維持したまま人通孔金物１００が有する上面板１２１に対して、直接住宅土台４００を支えることが可能となる。 The communication hole 300 formed in this way makes it possible to keep the communication hole 300 in a necessary and sufficient size even if the upper part of the foundation rising wall portion 210 is opened. Furthermore, by strengthening the upper side of the opened passage hole 300 with the trapezoidal beam 120, structural deformation is suppressed by the arch effect, and the upper surface plate of the passage hole hardware 100 has while maintaining the size of the passage hole 300. It is possible to directly support the housing base 400 with respect to 121.

また人通孔金物１００は、上面板１２１と側面板１１１および底面板１１２に複数設けられたアンカー孔１１３に挿入されたアンカーボルト１３１によって、住宅基礎２００と強固に碇着され、上部荷重に起因する全応力を基礎全体で効率よく均一に負担できるので、全体的に基礎構造のバランスが向上し、上部構造物の安定に資することができる。 Further, the passage hole hardware 100 is firmly anchored to the housing foundation 200 by anchor bolts 131 inserted into a plurality of anchor holes 113 provided in the top plate 121, the side plate 111, and the bottom plate 112, and is caused by the upper load. Since the total stress to be applied can be efficiently and uniformly applied to the entire foundation, the balance of the foundation structure can be improved as a whole, which can contribute to the stability of the superstructure.

図２は、人通孔金物の組立詳細を示す斜視図である。
図２に示すように、枠体１１０は、アングルリブ１１４有する２枚の側面板１１１と、アングルリブ１１５を有する底面板１１２とからなっている。 FIG. 2 is a perspective view showing the assembly details of the human passage metal fitting.
As shown in FIG. 2, the frame body 110 includes two side plate 111s having angle ribs 114 and a bottom plate 112 having angle ribs 115.

アングルリブ１１４およびアングルリブ１１５は、側面板１１１および底面板１１２の座屈防止用の補強材であって、全体的に剛性を増し、組み立て時の歪みを防止するとともに、人通孔金物１００の水平、垂直を保ち、側面板の局部座屈を防ぎ、かつ人通孔金物１００と打設されるコンクリートとの碇着をよくするために設置されている。 The angle ribs 114 and the angle ribs 115 are reinforcing materials for preventing buckling of the side plate 111 and the bottom plate 112, and increase the rigidity as a whole to prevent distortion during assembly, and the through-hole hardware 100. It is installed to maintain horizontal and vertical, prevent local buckling of the side plate, and improve the adhesion between the through-hole hardware 100 and the concrete to be cast.

ここで、人通孔金物１００の底面部においては、底面板１１２の両端部の座屈防止と、圧密時の変形防止のために、底面板１１２の下面かつ底面板１１２の長辺方向の外側端部に、互いに向き合うようにアングルリブ１１５が溶着されている。 Here, in the bottom surface portion of the through-hole hardware 100, in order to prevent buckling of both ends of the bottom surface plate 112 and to prevent deformation during consolidation, the bottom surface of the bottom surface plate 112 and the outside of the bottom surface plate 112 in the long side direction. Angle ribs 115 are welded to the ends so as to face each other.

また同様に、人通孔金物１００の側面部においても、側面板１１１の座屈防止の補強のために、側面視で住宅基礎２００の長辺方向に対向する２枚の側面板１１１の外側かつ、側面板１１１の長辺方向の外側端部に、互いに向き合うようにアングルリブ１１４が溶着されている。 Similarly, also on the side surface portion of the passage hole hardware 100, in order to reinforce the buckling prevention of the side plate 111, the outside of the two side plate 111s facing the long side direction of the housing foundation 200 in a side view and The angle ribs 114 are welded to the outer ends of the side plate 111 in the long side direction so as to face each other.

図３は、人通孔金物の接合方法を示す分解図である。
図３に示すように、人通孔金物１００は、上面板１２１および台形フランジ板１２２からなる台形梁１２０と、２枚の側面板１１１および底面板１１２からなる枠体１１０とから組み立てられる。 FIG. 3 is an exploded view showing a method of joining the human passage metal fittings.
As shown in FIG. 3, the passage hole metal fitting 100 is assembled from a trapezoidal beam 120 composed of a top plate 121 and a trapezoidal flange plate 122, and a frame body 110 composed of two side plate 111 and a bottom plate 112.

枠体１１０と台形梁１２０との接合方法の一例を以下に示す。
枠体１１０を構成する側面板１１１と底面板１１２との接合は、側面板１１１の下端でアングルピース１１６を介して直角に取付けられる。また枠体１１０と台形梁１２０との接合は、側面板１１１の上端でアングルピース１２４を介して直角に取付けられる。 An example of a method of joining the frame body 110 and the trapezoidal beam 120 is shown below.
The joint between the side plate 111 and the bottom plate 112 constituting the frame body 110 is attached at a right angle at the lower end of the side plate 111 via the angle piece 116. Further, the joint between the frame body 110 and the trapezoidal beam 120 is attached at a right angle at the upper end of the side plate 111 via the angle piece 124.

これらの接合は、溶接または、あらかじめ設けられた取付穴ａに、取付ナット１１７、１２５、および取付ボルト１１８、１２６によって結合される。なお、取付ナット１１７、１２５は取付穴ａの位置に合わせて溶着してあるとよい。
また工期短縮のため、台形梁１２０の接合部を先に溶着しておくことも可能であり、工程上効率的である。 These joints are welded or joined to the pre-provided mounting holes a by mounting nuts 117, 125 and mounting bolts 118, 126. The mounting nuts 117 and 125 may be welded according to the position of the mounting hole a.
Further, in order to shorten the construction period, it is possible to weld the joint portion of the trapezoidal beam 120 first, which is efficient in the process.

アングルピース１１６は、底面板１１２の上面の短辺端部から側面板１１１の厚さだけ長辺方向内側に入った位置に互いに向き合う方向で溶着される。同様に、アングルピース１２４は、上面板１２１の下面の短辺端部から側面板１１１の厚さだけ長辺方向内側に入った位置に互いに向き合う方向で溶着される。 The angle piece 116 is welded in a direction facing each other from the short side end portion of the upper surface of the bottom plate 112 to a position inside the long side direction by the thickness of the side plate 111. Similarly, the angle piece 124 is welded in a direction facing each other from the short side end portion of the lower surface of the upper surface plate 121 to a position inside the long side direction by the thickness of the side plate 111.

また、側面板１１１と底面板１１２とが垂直に固定された側面の４カ所の隅部に金属製の板材を垂直三角形に加工したコーナーリブ１１９を溶着することで、人通孔金物１００の剛性をさらに増すことができる。 Further, by welding corner ribs 119 made by processing a metal plate material into a vertical triangle at four corners on the side surface where the side plate 111 and the bottom plate 112 are vertically fixed, the rigidity of the through-hole hardware 100 is obtained. Can be further increased.

また本実施例では、枠体１１０と台形梁１２０とを接合する際に、溶着または取付ナット１２５と取付ボルト１２６とで接合する例を挙げたが、工事現場の状況次第で、取付ボルト１２６を有する長ナットを用いると良い。また人通孔金物１００の外側に溶着し、人通孔金物１００の内側から取付ボルト１２６で固定することも選択できる。 Further, in this embodiment, when joining the frame body 110 and the trapezoidal beam 120, an example of joining by welding or joining the mounting nut 125 and the mounting bolt 126 has been given, but depending on the situation at the construction site, the mounting bolt 126 may be used. It is preferable to use a long nut that has. It is also possible to select by welding to the outside of the through-hole hardware 100 and fixing it from the inside of the through-hole hardware 100 with a mounting bolt 126.

これにより、人通孔３００を有する住宅基礎２００の形成後、何らかの事情により台形梁１２０を取り外す必要が発生したときに、人通孔金物１００の内側から緊結した取付ボルト１２６を取り外すだけで、容易に台形梁１２０を取り外すことが可能となる。 As a result, when it becomes necessary to remove the trapezoidal beam 120 for some reason after the housing foundation 200 having the passage hole 300 is formed, it is easy to simply remove the mounting bolt 126 tightly connected from the inside of the passage hole hardware 100. The trapezoidal beam 120 can be removed.

なお、２枚の側面板１１１と底面板１１２とには、あらかじめ所望の位置にアンカー孔１１３があけられている。これは人通孔金物１００を固定するために使用するものであり、固定方法については後述する。 Anchor holes 113 are previously formed at desired positions in the two side plate 111 and the bottom plate 112. This is used for fixing the through-hole hardware 100, and the fixing method will be described later.

図４は、基礎立ち上がり壁部に人通孔を形成するために、コンクリート型枠内に人通孔金物を設置した状態を示す斜視図である。
図４に示すように、人通孔３００を有する基礎立ち上がり壁部２１０を形成するための地業として割栗、目つぶし、突き固め、モルタル均しの後、コンクリート型枠６００の設置と配筋５００の組み立て、および人通孔金物１００の設置とが同時並行的に進められる。 FIG. 4 is a perspective view showing a state in which a passage hole hardware is installed in a concrete formwork in order to form a passage hole in the foundation rising wall portion.
As shown in FIG. 4, as the groundwork for forming the foundation rising wall portion 210 having the passage hole 300, after cracking, blinding, tamping, and leveling the mortar, the concrete formwork 600 is installed and the reinforcement 500 is arranged. Assembly and installation of the communication hole hardware 100 are carried out in parallel.

その間、人通孔金物１００がコンクリート型枠６００内の所定の位置に挟み込まれるように設置され、配筋５００の配筋時に、人通孔金物１００の枠体１１０が有する側面板１４１と底面板１４２から突き出ているアンカーボルト１３１とを結束させる。 During that time, the passage hole hardware 100 is installed so as to be sandwiched at a predetermined position in the concrete form 600, and when the reinforcement 500 is arranged, the side plate 141 and the bottom plate of the frame body 110 of the passage hole hardware 100 are provided. Bundling the anchor bolt 131 protruding from 142.

人通孔金物１００は配筋された配筋５００の端部に結線あるいは点溶接で固定され、人通孔金物１００の上面板１２１のコンクリート型枠６００の天端が一致するように設置され、配筋５００を囲うように、反対側の対向する型枠メタルフォーム６１０で人通孔金物１００を挟持するように止め金物で緊結して、人通孔金物１００の人通空間の開口部を塞ぐように設置される。 The passage hole hardware 100 is fixed to the end of the bar arrangement 500 by wire connection or spot welding, and is installed so that the top ends of the concrete form 600 of the top plate 121 of the passage hole hardware 100 coincide with each other. The opening of the communication space of the communication hole metal fitting 100 is closed by binding the communication hole metal fitting 100 with a stopper so as to sandwich the communication hole metal fitting 100 with the opposite formwork metal foam 610 so as to surround the reinforcing bar 500. Will be installed.

この時、枠体１１０の外側に沿わせた補助筋５１１を配筋し、突き出たアンカーボルト１３１との結束を密にすると、さらに人通孔金物１００と住宅基礎２００との碇着が強固となる。 At this time, by arranging auxiliary bars 511 along the outside of the frame body 110 and tightly binding the protruding anchor bolts 131, the anchorage between the human communication hole hardware 100 and the housing foundation 200 becomes stronger. Become.

基礎立ち上がり部壁部２１０の配筋５００は、人通孔３００が形成される位置を除いた部位に組み立てられ、人通孔金物１００を形成する枠体１１０の２枚の側面板１１１と上面板１２１から突き出た複数のアンカーボルト１３１と結束または点溶接のうえ、そのままコンクリート２１１を打設、硬化した後、人通孔金物１００を埋め込んだまま脱型すれば、完成した人通孔金物１００が現れる。 The reinforcement 500 of the wall portion 210 of the foundation rising portion is assembled at a portion other than the position where the passage hole 300 is formed, and the two side plates 111 and the top plate of the frame body 110 forming the passage hole hardware 100 are formed. After bundling or spot welding with a plurality of anchor bolts 131 protruding from 121, the concrete 211 is cast and hardened as it is, and then the die is removed while the human hole metal 100 is embedded, so that the completed human hole metal 100 can be obtained. appear.

図５は、設置されたコンクリート型枠の内部で人通孔金物が補助筋に固定された様子を示す図である。
図５に示すように、人通孔金物１００は、アンカーボルト１３１によって配筋５００に固定されている。 FIG. 5 is a diagram showing a state in which the passage hole hardware is fixed to the auxiliary bar inside the installed concrete formwork.
As shown in FIG. 5, the passage hole metal fitting 100 is fixed to the reinforcing bar 500 by the anchor bolt 131.

具体的には、人通孔金物１００が有する側面板１１１と底面板１１２とに、あらかじめ設けられたアンカー孔１１３にアンカーボルト１３１が人通孔金物１００の内側から外側に向かって差し込まれて側面板１１１と底面板１１２とに溶着される。 Specifically, the anchor bolts 131 are inserted into the anchor holes 113 provided in advance in the side plate 111 and the bottom plate 112 of the human passage metal fitting 100 from the inside to the outside to the side. It is welded to the face plate 111 and the bottom plate 112.

人通孔金物１００の周囲から突出、固定されたアンカーボルト１３１は、人通孔金物１００の周囲の配筋５００に結束あるいは点溶接で固定される。
例えば底面板１１２に形成されたアンカー孔１１３に溶着されたアンカーボルト１３１は、人通孔金物１００から下向きにアンカーボルト１３１が突出するように固定される。 Anchor bolts 131 protruding and fixed from the periphery of the through-hole hardware 100 are bound or spot-welded to the reinforcing bars 500 around the through-hole hardware 100.
For example, the anchor bolt 131 welded to the anchor hole 113 formed in the bottom plate 112 is fixed so that the anchor bolt 131 projects downward from the passage hole hardware 100.

また側面板１１１に形成されたアンカー孔１１３に溶着されたアンカーボルト１３１は、人通孔金物１００から水平方向にアンカーボルト１３１が突出するように固定される。そして、人通孔金物１００から水平方向に突出したアンカーボルト１３１は、人通孔金物１００の側面に水平方向に配筋された主筋５２０または補助筋５１１に結束線あるいは点溶接により固定される。 Further, the anchor bolt 131 welded to the anchor hole 113 formed in the side plate 111 is fixed so that the anchor bolt 131 protrudes horizontally from the passage hole hardware 100. Then, the anchor bolt 131 protruding horizontally from the through-hole metal fitting 100 is fixed to the main bar 520 or the auxiliary bar 511 horizontally arranged on the side surface of the through-hole metal fitting 100 by a binding wire or spot welding.

これにより人通孔金物１００は配筋５００に固定され、また人通孔３００の人通空間を覆うようにコンクリート型枠６００が挟み込んで設置されるので、人通孔金物１００をコンクリート型枠６００の内部に正確に固定することができる。 As a result, the passage hole hardware 100 is fixed to the reinforcing bar 500, and the concrete formwork 600 is sandwiched and installed so as to cover the passage space of the passage hole 300. Therefore, the passage hole hardware 100 is placed in the concrete form 600. Can be fixed exactly inside the.

図６は、コンクリート型枠内にコンクリートを打設した様子を示す図である。
図６に示すように、人通孔金物１００はコンクリート型枠６００に覆われているため、外観から人通孔金物１００は、人通孔金物１００が有する台形梁１２０しか見えていない状況である。 FIG. 6 is a diagram showing a state in which concrete is placed in a concrete formwork.
As shown in FIG. 6, since the communication hole metal fitting 100 is covered with the concrete formwork 600, only the trapezoidal beam 120 of the communication hole metal fitting 100 can be seen from the outside. ..

図７は、コンクリート硬化後にコンクリート型枠の撤去作業が人通孔まで進んだ様子を示す図である。
コンクリート型枠６００内に、人通孔金物１００が設置された基礎立ち上がり壁部２１０のうち、コンクリート２１１が流れ込まなかった人通孔金物１００の内側の人通空間はそのまま空間として残り、その空間部分の人通孔金物１００が人通孔３００として基礎立ち上がり壁部２１０に形成される。
また基礎立ち上がり壁部２１０に形成された人通孔３００には、脱型後、人通孔金物１００として、そのまま人通孔３００の側壁を形成する。 FIG. 7 is a diagram showing how the work of removing the concrete formwork has progressed to the passage hole after the concrete has hardened.
Of the foundation rising wall 210 in which the communication hole hardware 100 is installed in the concrete formwork 600, the communication space inside the communication hole hardware 100 from which the concrete 211 did not flow remains as it is, and the space portion thereof. The human passage hole metal 100 is formed in the foundation rising wall portion 210 as a human passage hole 300.
Further, in the passage hole 300 formed in the foundation rising wall portion 210, after demolding, the side wall of the passage hole 300 is formed as it is as the passage hole hardware 100.

本発明の人通孔金物１００は、それ自体で強度を有しており、基礎立ち上がり壁部２１０と人通孔金物１００とは密着しているので、基礎からの伝達応力に対して安全である。また人通孔金物１００が有するアングルリブ１１４、１１５によって、側面板１１１と底面板１１２の局部破壊に対する抵抗力が増す。 The through-hole hardware 100 of the present invention has strength by itself, and since the foundation rising wall portion 210 and the through-hole hardware 100 are in close contact with each other, it is safe against the transmission stress from the foundation. .. Further, the angle ribs 114 and 115 of the through-hole hardware 100 increase the resistance to local destruction of the side plate 111 and the bottom plate 112.

Therefore, the same components as those in the first embodiment will be designated by the same reference numerals, and the description thereof will be omitted as appropriate.

図８は、第２の実施の形態に係る人通孔金物の詳細を示す斜視図である。
図８に示すように、人通孔金物１００は、２枚の側面板１４１と底面板１４２と２枚の台形フランジ板１４３とからなる枠型函体１４０と、台形梁１２０を備えている。 FIG. 8 is a perspective view showing details of the through-hole hardware according to the second embodiment.
As shown in FIG. 8, the passage hole hardware 100 includes a frame-shaped box 140 composed of two side plate 141, a bottom plate 142, and two trapezoidal flange plates 143, and a trapezoidal beam 120.

台形フランジ板１４３は短辺方向断面が「コの字」状の形状をした板材であり、台形フランジ板１２２と同様の形状をしている。台形フランジ板１４３は、台形梁１２０が有する台形フランジ板１２２と台形フランジ板１４３とは上下対称に設けられる。 The trapezoidal flange plate 143 is a plate material having a "U-shaped" cross section in the short side direction, and has the same shape as the trapezoidal flange plate 122. The trapezoidal flange plate 143 is provided so that the trapezoidal flange plate 122 and the trapezoidal flange plate 143 of the trapezoidal beam 120 are vertically symmetrical.

台形フランジ板１４３は、側面視で住宅基礎２００の長手方向に沿って、底面板１４２の長手方向の両側面に垂直方向に固定される。固定位置は、台形フランジ板１４３の側面視の長手方向両端部に近い台形曲部が、底面板１４２と側面板１４１との接合部を覆うように、かつ台形フランジ板１４３の中央部底面辺が、底面板１４２高さ方向が同等位置になるように取付けられ、長手方向側面視で折板アーチ状に構成される。
これにより枠型函体１４０は、水平に繋いだ水平梁よりも断面諸係数が増加する。また短辺方向断面も溝形に形成されるので、曲げ強度が増加する。 The trapezoidal flange plate 143 is vertically fixed to both side surfaces of the bottom plate 142 in the longitudinal direction along the longitudinal direction of the housing foundation 200 in a side view. The fixed position is such that the trapezoidal curved portions near both ends in the longitudinal direction of the trapezoidal flange plate 143 cover the joint between the bottom plate 142 and the side plate 141, and the bottom surface side of the central portion of the trapezoidal flange plate 143 is located. , The bottom plate 142 is attached so that the height directions are the same, and is configured in a folded plate arch shape in the longitudinal side view.
As a result, the frame-type box 140 has more cross-sectional coefficients than the horizontally connected horizontal beams. Further, since the cross section in the short side direction is also formed in a groove shape, the bending strength is increased.

なお本実施例では、人通孔金物１００の上下が対称になるように構成したが、上下の台形フランジ板１２２、１４３を逆対称にし、台形の山が同方向になるようにして、対向する２枚の側面板１４１の下部側を短くし、代わりに側面板１４１に備えられたアングルリブ１４４を延長して脚部とすることで人通孔金物１００の水平安定性を保つように構成することも可能である。 In this embodiment, the upper and lower trapezoidal metal fittings 100 are configured to be symmetrical, but the upper and lower trapezoidal flange plates 122 and 143 are inversely symmetrical so that the trapezoidal peaks are in the same direction and face each other. The lower side of the two side plate 141 is shortened, and instead the angle rib 144 provided on the side plate 141 is extended to form a leg portion so as to maintain the horizontal stability of the passage hole hardware 100. It is also possible.

〔第３の実施の形態〕
次に、本発明の第３の実施の形態について説明する。本実施の形態の人通孔金物は、枠体１１０の形状が異なる以外は、第１の実施の形態で示した構成とほぼ同様である。このため、上記第１の実施の形態とほぼ同様の構成部分については同一の符号を付すなどして適宜その説明を省略する。 [Third Embodiment]
Next, a third embodiment of the present invention will be described. The through-hole hardware of the present embodiment is substantially the same as the configuration shown in the first embodiment except that the shape of the frame body 110 is different. Therefore, the same components as those in the first embodiment will be designated by the same reference numerals, and the description thereof will be omitted as appropriate.

図９は、第３の実施の形態に係る人通孔金物の詳細を示す斜視図である。
図９に示すように、人通孔金物１００は、台形梁１２０と、枠型函体１５０とを備えている。 FIG. 9 is a perspective view showing details of the through-hole hardware according to the third embodiment.
As shown in FIG. 9, the passage hole hardware 100 includes a trapezoidal beam 120 and a frame-shaped box 150.

枠型函体１５０は、短辺方向断面において上辺部が開放された「コの字」状に側面板１１１と底面板１１２とが接合された枠体１１０の角部を曲面加工したものである。
枠型函体１５０が有する側面板１５１は、側面板１１１と底面板１１２との位置に沿って曲面を有した一枚の金属板から加工さる。 The frame-shaped box 150 is a curved surface of a frame 110 in which a side plate 111 and a bottom plate 112 are joined in a "U" shape with an open upper side in a cross section in the short side direction. ..
The side plate 151 of the frame type box 150 is processed from a single metal plate having a curved surface along the positions of the side plate 111 and the bottom plate 112.

また側面板１５１の外側には、側面板１５１に沿って溶着された２本の平鋼リブ１５２が側面板１５に平行するように溶着されている。平鋼リブ１５２は、台形梁１２０と枠体１１０との接合の歪みを防止すると共に、人通孔金物１００の水平、垂直を保ち、側面板１５１の局部破壊を防止する。 Further, on the outside of the side plate 151, two flat steel ribs 152 welded along the side plate 151 are welded so as to be parallel to the side plate 15. The flat steel rib 152 prevents distortion of the joint between the trapezoidal beam 120 and the frame body 110, keeps the perforated hardware 100 horizontal and vertical, and prevents local destruction of the side plate 151.

これにより住宅基礎２００に形成される人通孔３００は人通孔金物１００によって完全に補強されるので、住宅基礎２００に形成される立ち上がり部壁部２１０下方向からの反力に対しても抵抗力のある人通孔３００を形成することが出来る。 As a result, the passage hole 300 formed in the housing foundation 200 is completely reinforced by the passage hole hardware 100, so that the rising portion wall portion 210 formed in the housing foundation 200 also resists the reaction force from below. It is possible to form a powerful human passage hole 300.

また人通孔金物１００と形成される人通孔３００の下部とが接する面を曲面にすることで、枠体１１０の下辺の隅角部が形成されないため、人通孔金物１００の下部にかかる応力が分散されるので、基礎立ち上がり壁部２１０への設置に際し、人通孔金物１００が安定しやすい。 Further, by making the surface in contact with the lower portion of the passage hole 300 formed with the passage hole hardware 100 curved, the lower corner portion of the lower side of the frame 110 is not formed, so that the lower portion of the passage hole hardware 100 is covered. Since the stress is dispersed, the passage hole metal fitting 100 is likely to be stable when it is installed on the foundation rising wall portion 210.

また人通孔金物１００の下部を曲面にすることで、形成される人通孔３００の下部隅部へ集中してしまう応力が曲面に沿って分散されるので、人通孔３００の欠損を防止することが出来る。 Further, by making the lower part of the passage hole hardware 100 curved, the stress concentrated on the lower corner of the formed passage hole 300 is dispersed along the curved surface, so that the passage hole 300 is prevented from being damaged. Can be done.

また人通孔金物１００の下部を曲面にすることで、コンクリート２１１の打設時の人通孔金物１００による抵抗が少なくなるので、打設したコンクリート２１１が人通孔金物１００の下側にも流動しやすく、ジャンカ（豆板）が出にくい。これにより、住宅基礎２００と人通孔金物１００とが一体化しやすくなる。 Further, by making the lower part of the through-hole hardware 100 curved, the resistance due to the through-hole hardware 100 at the time of placing the concrete 211 is reduced, so that the placed concrete 211 is also placed on the lower side of the through-hole hardware 100. It is easy to flow and it is difficult for junkers (bean plates) to come out. This makes it easier to integrate the housing foundation 200 and the human communication hole hardware 100.

なお、本実施例では、コンクリート２１１の打設前にコンクリート型枠６００の間に人通孔金物を設置し、コンクリート２１１を打設、またコンクリート２１１硬化後に耐力を備えた人通孔３００が形成される例を示したが、あらかじめ形成された基礎立ち上がり部壁部２１０に人通孔３００を形成し、その形成された人通孔３００に人通孔金物１００を嵌め込むことで、人通孔３００を補強するようにしてもよい。 In this embodiment, the passage hole hardware is installed between the concrete formwork 600 before the concrete 211 is placed, the concrete 211 is placed, and the communication hole 300 having a proof stress is formed after the concrete 211 is hardened. As shown in the example, the passage hole 300 is formed in the pre-formed foundation rising portion wall portion 210, and the passage hole metal 100 is fitted into the formed passage hole 300 to form a passage hole. The 300 may be reinforced.
