本発明は、設備用基礎及び設備用基礎の施工方法に関する。 The present invention relates to a facility foundation and a facility foundation construction method.
従来、所定の設備機器を支持する基礎として特許文献１に開示されている発明が知られている。 Conventionally, the invention disclosed in Patent Document 1 is known as a basis for supporting predetermined equipment.
この特許文献１に開示された機械基礎は、受板にアンカーボルト用の穴を設け、当該穴にねじ側を上方に突出させてアンカーボルトを挿通し、当該受板の上下でねじ部に螺着したナットでアンカーボルトを受板に定着し、基礎コンクリートを、その上面を受板の上面のレベルと一致させて受板とアンカーボルトを囲んで打設することとしている。 The machine foundation disclosed in Patent Document 1 is provided with a hole for an anchor bolt in a receiving plate, a screw side is protruded upward in the hole, an anchor bolt is inserted, and a screw portion is screwed up and down the receiving plate. The anchor bolt is fixed to the receiving plate with the attached nut, and the foundation concrete is placed around the receiving plate and the anchor bolt so that the upper surface of the foundation concrete coincides with the level of the upper surface of the receiving plate.
具体的には、上述した機械基礎は、受板とアンカーボルトを囲んで基礎コンクリートを打設したものであり、アンカーボルトを定着した受板は上面を除いて基礎コンクリートに固定されるので、地震時や稼動時に基礎の上部に載置された機械が振動した場合でも、基礎コンクリートによって振動が阻止される為、基礎コンクリートのひび割れを防止することができるものである。 Specifically, the above-mentioned machine foundation is constructed by placing foundation concrete around the receiving plate and anchor bolt, and the receiving plate to which the anchor bolt is fixed is fixed to the foundation concrete except for the upper surface. Even when the machine placed on the upper part of the foundation vibrates during operation or operation, since the vibration is blocked by the foundation concrete, cracking of the foundation concrete can be prevented.
ところで、上述した機械基礎上に所定の機械を載置する場合、先ず上述した基礎を形成した後、コンクリートを打設することが必要であり、当該打設後のコンクリートに機械の重量を負担させる為、コンクリートが硬化した後でなければ機械を載置することができないという問題があった。型枠等を形成し、コンクリートの養生を行った後、機械の載置を行う為には通常２日以上の日数を要するものであった。又、主にコンクリート部に機械の重量を負担させるものである為、一定水準のワーカビリティやフィニッシャビリティが要求されるものであり、コンクリートの品質管理が煩雑なものであった。 By the way, when placing a predetermined machine on the above-described machine foundation, it is necessary to first cast the concrete after the above-mentioned foundation is formed, and the concrete after the placement bears the weight of the machine. Therefore, there has been a problem that the machine can only be placed after the concrete has hardened. After forming the formwork and curing the concrete, it usually takes two or more days to place the machine. Moreover, since the weight of the machine is mainly borne on the concrete part, a certain level of workability and finishability is required, and the quality control of the concrete is complicated.
そこで本発明はこの様な実情に鑑みてなされたものであり、極めて容易に設置することができ、コンクリートの品質管理を容易にすることができ、さらに高強度を有する設備用基礎を提供することを目的とする。 Accordingly, the present invention has been made in view of such circumstances, and can provide a foundation for equipment that can be installed very easily, can easily control the quality of concrete, and has high strength. With the goal.
上述した課題を解決する為に、本発明に係る設備用基礎は、所定の設備を支持する設備用基礎であって、前記設備を設置しようとする領域に所定の間隔を持って載置され、前記設備を固定する、少なくとも２つのベース部材と、前記ベース部材を連結する連結部材とを備え、前記ベース部材を用いてコンクリートの流出を防ぐ枠を形成し、前記枠内にはコンクリートが充填されることを特徴としている。 In order to solve the above-mentioned problems, the foundation for equipment according to the present invention is a foundation for equipment that supports predetermined equipment, and is placed at a predetermined interval in an area where the equipment is to be installed. The frame includes at least two base members for fixing the equipment and a connecting member for connecting the base members, and forms a frame for preventing the outflow of concrete using the base member, and the frame is filled with concrete. It is characterized by that.
この構成によれば、ベース部材が設備の重量を負担することとなる為、コンクリートの硬化を待つことなく設備を載置することができる。さらに連結部材を用いて２つのベース部材を連結することによって、２つのベース部材の距離を保つことができ、２つのベース部材によって形成される枠の形状を一定に保つことができる。また、コンクリートに設備機器の重量を負担させない為、煩雑なコンクリートの品質管理を行う必要は無い。 According to this configuration, since the base member bears the weight of the equipment, the equipment can be placed without waiting for the concrete to harden. Further, by connecting the two base members using the connecting member, the distance between the two base members can be maintained, and the shape of the frame formed by the two base members can be kept constant. In addition, since the concrete does not bear the weight of equipment, there is no need to perform complicated concrete quality control.
さらに、前記連結部材は棒状の部材であって、前記枠内に形成され、前記連結部材に生じたせん断力を、前記設備を設置しようとする領域を形成する土台に伝達するものであることが好ましい。すなわち、設備用基礎に水平方向に外力が加わった場合でも、設備用基礎全体が水平方向に移動することを防止することができる。 Further, the connecting member is a rod-shaped member, and is formed in the frame, and transmits the shearing force generated in the connecting member to a base forming a region where the facility is to be installed. preferable. That is, even when an external force is applied to the facility foundation in the horizontal direction, the entire facility foundation can be prevented from moving in the horizontal direction.
さらにまた、前記ベース部材はブロック状に形成され、前記ベース部材の上面に、前記所定の設備を固定する固定部材を備えることが好ましい。ベース部材をブロック上に形成することによって、容易にベース部材を製造することができる。また、ブロック部材の上面に固定部材を備えることによって、ベース部材に所定の設備機器を強固に固定することができる。 Furthermore, it is preferable that the base member is formed in a block shape and includes a fixing member for fixing the predetermined equipment on the upper surface of the base member. By forming the base member on the block, the base member can be easily manufactured. Further, by providing the fixing member on the upper surface of the block member, it is possible to firmly fix the predetermined equipment to the base member.
この様な構成を有する設備用基礎は、極めて容易に設置することができ、コンクリートの品質管理を用意に行うことができ、さらに高強度を有するものである。 The foundation for facilities having such a configuration can be installed very easily, can be prepared for quality control of concrete, and has high strength.
以下、本発明を適用した具体的な実施の形態について図面を参照しながら詳細に説明する。 Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.
本発明に係る設備用基礎は、例えば２つのベース部材を用いて基礎の形状を決定し、生コンクリートをベース部材の間に流入することで形成される。基礎の上部に所定の設備機器を載置するとき、当該設備機器の下部に形成された支持部がベース部材の上面に形成されたレールに差し込まれる様にベース部材の間隔を調整し、当該設備機器を載置するものである。すなわち、生コンクリートの硬化を待たずして設備用基礎に所定の設備機器を載置することができるものである。 The equipment foundation according to the present invention is formed, for example, by determining the shape of the foundation using two base members and flowing ready-mixed concrete between the base members. When placing predetermined equipment on the upper part of the foundation, the interval between the base members is adjusted so that the support part formed on the lower part of the equipment is inserted into the rail formed on the upper surface of the base member. Equipment is to be placed. That is, a predetermined equipment can be placed on the equipment foundation without waiting for the ready-mixed concrete to harden.
先ず、本発明に係る設備用基礎の第１の実施の形態について詳細な説明をする。図１は、設備用基礎を示す斜視図であり、図２は設備用基礎の上面図であり、図３はＡ‐Ａ´断面の断面図である。 First, the first embodiment of the equipment foundation according to the present invention will be described in detail. FIG. 1 is a perspective view showing an equipment foundation, FIG. 2 is a top view of the equipment foundation, and FIG. 3 is a cross-sectional view taken along the line AA ′.
設備用基礎は、２つのベース部材１と、２つのベース部材１を連結する連結部材としてのアンカーボルト２と、アンカーボルト２に生じたせん断力を、設備を設置しようとする領域を形成する土台に伝達する伝達部材としての異型鉄筋３と、ベース部材１と共にコンクリートの流出を防ぐ枠を形成するプレート４と、設備をベース部材１の上面に固定する固定部材としてのレール５によって構成されている。 The base for equipment includes two base members 1, anchor bolts 2 as connecting members for connecting the two base members 1, and a base that forms shearing force generated in the anchor bolts 2 in an area where equipment is to be installed. It is constituted by a deformed reinforcing bar 3 as a transmission member that transmits to the base plate, a plate 4 that forms a frame that prevents outflow of concrete together with the base member 1, and a rail 5 as a fixing member that fixes the equipment to the upper surface of the base member 1. .
ベース部材１は、上部に所定の設備機器が載置される部材であり、例えばコンクリート等をブロック状に形成することで構成されている。又、ベース部材１の寸法は、例えば１２０ｍｍ×１８０ｍｍ×７００ｍｍ程度である。設備基礎においては、２つのベース部材１が、設備を設置しようとする領域Ｐ、すなわちユーザが設備の設置を望む位置に所定の間隔を以って載置される。このとき、それぞれのベース部材１の長手面が平行に、且つ対向する様にベース部材１を載置する必要がある。又、レベラー等を用いてベース部材１が設置面に対して水平に設置されることが好ましい。尚、本実施の形態に於いては説明の便宜上、それぞれのベース部材１を形成する面の内、互いに対向する長手面を内側長手面１０とし、さらに設備用基礎は土の上に載置するものとする。 The base member 1 is a member on which predetermined equipment is placed on the upper portion, and is configured by, for example, forming concrete or the like in a block shape. The size of the base member 1 is, for example, about 120 mm × 180 mm × 700 mm. In the equipment foundation, the two base members 1 are placed at a predetermined interval in a region P where the equipment is to be installed, that is, a position where the user desires to install the equipment. At this time, it is necessary to place the base member 1 so that the longitudinal surfaces of the respective base members 1 are parallel and face each other. Moreover, it is preferable that the base member 1 is installed horizontally with respect to the installation surface using a leveler or the like. In the present embodiment, for convenience of explanation, out of the surfaces forming the respective base members 1, the opposing longitudinal surfaces are the inner longitudinal surfaces 10, and the equipment foundation is placed on the soil. Shall.
さらにベース部材１内部には、アンカーボルト２及びプレート４をそれぞれ固定するための六角長ナットが形成されている。これらの六角長ナットは、ベース部材１を養生する際に、それぞれの六角長ナットの端部が内側長手面１０表面に形成される様に形成されている。アンカーボルト２を固定する為の六角長ナット６ａは、例えば１つのベース部材１の内側長手面１０の高さ方向の中心線に沿って等間隔に３つ形成されている。ベース部材１を土に載置するとき、対向する六角長ナット６ａが同一の直線状に配列されている必要がある。アンカーボルト２をベース部材１に固定するとき、これら対向する２つの六角長ナット６ａにアンカーボルト２の端部をそれぞれ遊挿し、固定する。さらに、ドーナッツ状のユニクロナット６ｂを用いてアンカーボルト２を固定することで、基礎をより強固に形成することができる。プレート４を固定する六角長ナット７は、内側長手方向面１０の両端部近傍にそれぞれ２箇所形成されており、所定のボルト８を用いて２枚のプレート４をそれぞれ固定する。すなわち、２つのベース部材１と２枚のプレート４を用いて、後述するコンクリートの流出を防ぐ枠を形成する。 Further, a hexagonal long nut for fixing the anchor bolt 2 and the plate 4 is formed inside the base member 1. These hexagonal long nuts are formed so that the end of each hexagonal long nut is formed on the surface of the inner longitudinal surface 10 when the base member 1 is cured. For example, three hexagonal long nuts 6a for fixing the anchor bolt 2 are formed at equal intervals along the center line in the height direction of the inner longitudinal surface 10 of one base member 1. When the base member 1 is placed on the soil, the opposing hexagonal long nuts 6a need to be arranged in the same straight line. When the anchor bolt 2 is fixed to the base member 1, the end portions of the anchor bolt 2 are loosely inserted into the two opposing hexagonal long nuts 6a and fixed. Furthermore, the foundation can be more firmly formed by fixing the anchor bolt 2 using the donut-shaped UNIQLO nut 6b. Two hexagonal nuts 7 for fixing the plate 4 are formed in the vicinity of both end portions of the inner longitudinal surface 10, and the two plates 4 are fixed by using predetermined bolts 8. That is, the frame which prevents the outflow of the concrete mentioned later is formed using the two base members 1 and the two plates 4.
アンカーボルト２は、例えば３／８×３００の全ネジボルトを用いることが好ましい。このアンカーボルト２の両端を、先述した六角長ナット６ａにそれぞれ差し込むことで、２つのベース部材１に固定され、２つのベース部材１を連結する。２つのベース部材１を、アンカーボルト２を用いて連結することによって設備用基礎の水平方向の強度を高めることができる。 As the anchor bolt 2, it is preferable to use, for example, a 3/8 × 300 full screw bolt. By inserting both ends of the anchor bolt 2 into the hexagonal long nut 6a described above, the anchor bolt 2 is fixed to the two base members 1, and the two base members 1 are connected. By connecting the two base members 1 using the anchor bolts 2, the horizontal strength of the facility foundation can be increased.
異形鉄筋３は、アンカーボルト４に加わるせん断力を、設備を設置しようとする領域Ｐに伝達するものであり、例えば直径１０ｍｍの異形鉄筋である。又、異形鉄筋３の一端は鉤型に形成されており、アンカーボルト４の中心部近傍に引っ掛け、他端は土に埋め込まれている。このとき異形鉄筋３の根入れ深さは、例えば３００ｍｍ程度であることが好ましい。 The deformed reinforcing bar 3 transmits a shearing force applied to the anchor bolt 4 to a region P where the facility is to be installed, and is, for example, a deformed reinforcing bar having a diameter of 10 mm. Further, one end of the deformed reinforcing bar 3 is formed in a bowl shape, hooked in the vicinity of the center portion of the anchor bolt 4, and the other end is embedded in the soil. At this time, the depth of penetration of the deformed reinforcing bar 3 is preferably about 300 mm, for example.
プレート４は、例えば厚さ１０ｍｍ程度の樹脂板、又は厚さ２ｍｍ程度のステンレス板等によって構成されており、ダンプレートの長手方向の長さは、先述したベース部材１の間隔と同一であることが必要である。さらに先述の様に、プレート４の両端部は、所定のボルトを用いてプレート４と２つのベース部材１を固定することができる様に形成されている。 The plate 4 is made of, for example, a resin plate having a thickness of about 10 mm or a stainless plate having a thickness of about 2 mm, and the length of the damper plate in the longitudinal direction is the same as the interval between the base members 1 described above. is required. Further, as described above, both ends of the plate 4 are formed so that the plate 4 and the two base members 1 can be fixed using predetermined bolts.
レール５は、例えば幅２０ｍｍ程度のアルミ製のレールであり、レール５の長さはベース部材１の長手方向の長さと略同一であることが好ましい。レール５は、ベース部材１の上面の長手方向の中心線に沿って固定されており、六角長ナット６及び六角長ナット７と同様に、ベース部材１を養生するときに埋め込むことが好ましい。レール５は、それぞれのベース部材１に形成されることとなるが、レール５及び所定のボルト等を用いて設備機器をベース部材１に固定することができる。 The rail 5 is, for example, an aluminum rail having a width of about 20 mm, and the length of the rail 5 is preferably substantially the same as the length of the base member 1 in the longitudinal direction. The rail 5 is fixed along the longitudinal center line of the upper surface of the base member 1 and is preferably embedded when the base member 1 is cured, like the hexagonal long nut 6 and the hexagonal long nut 7. The rails 5 are formed on the respective base members 1, but the equipment can be fixed to the base members 1 using the rails 5 and predetermined bolts.
図４ａ及び図４ｂは、設備用基礎上に、所定の設備機器を載置する工程を示した斜視図である。先述した方法で２つのベース部材１、アンカーボルト２、異形鉄筋３、及びプレート４を設置した後、生コンクリート１１を先述した枠内部に流入させ、設備機器１２の脚部１２ａを、例えばボルト等を用いてベース部材１に固定させる。このとき、枠に流入させた生コンクリート１１の硬化を待つことなく設備機器を載置することができる。 4a and 4b are perspective views showing a process of placing predetermined equipment on the equipment foundation. After the two base members 1, the anchor bolt 2, the deformed rebar 3 and the plate 4 are installed by the above-described method, the ready-mixed concrete 11 is caused to flow into the above-described frame, and the leg portion 12a of the equipment device 12 is, for example, a bolt The base member 1 is fixed using At this time, the equipment can be placed without waiting for the ready-mixed concrete 11 flowing into the frame to harden.
この様な設備用基礎は、設置場所に於いて施工を行う為、運搬等を容易に行うことができ、且つ、枠内に流入させたコンクリートの硬化を待つ必要が無い為、短時間で施工を完成させることができるものである。 Since such a foundation for equipment is installed at the installation location, it can be easily transported, etc., and it is not necessary to wait for the concrete that has flowed into the frame to be cured. Can be completed.
本発明の発明者等による実験では、本発明に係る設備用基礎は、施工開始から約３０分程度で、十分な強度を有する基礎を完成させることができるものである。さらに、発明者等による実験ではレール５は、最大で１９．５ｋＮの引抜強度を得ることができたものである。 In experiments by the inventors of the present invention, the foundation for facilities according to the present invention can complete a foundation having sufficient strength in about 30 minutes from the start of construction. Furthermore, in experiments by the inventors, the rail 5 has a maximum pulling strength of 19.5 kN.
以下、本発明に係る設備用基礎の第２の実施の形態について詳細な説明をする。第２の実施の形態に係る設備用基礎は、第１の実施の形態に係る設備用基礎と同一の構成を有する箇所がある為、その点については詳細な説明を省略し、差異のある箇所について詳細な説明を行う。 Hereinafter, the second embodiment of the facility foundation according to the present invention will be described in detail. Since the equipment foundation according to the second embodiment has the same configuration as the equipment foundation according to the first embodiment, a detailed description thereof is omitted and there is a difference. A detailed description will be given.
図５は、第２の実施の形態に係る設備用基礎の斜視図である。第２の実施の形態に係る設備用基礎は、２つのベース部材１と、アンカーボルト２と、異形鉄筋３と、プレート４と、レール１５ａ、１５ｂとによって構成されている。２つのベース部材１、アンカーボルト２、異形鉄筋３、及びプレート４の構成については第１の実施の形態に於いて詳細な説明を行った為、省略する。 FIG. 5 is a perspective view of the equipment foundation according to the second embodiment. The equipment foundation according to the second embodiment includes two base members 1, anchor bolts 2, deformed reinforcing bars 3, plates 4, and rails 15a and 15b. Since the configuration of the two base members 1, the anchor bolt 2, the deformed reinforcing bar 3, and the plate 4 has been described in detail in the first embodiment, a description thereof will be omitted.
２つのベース部材１の上面にはそれぞれレール１５ａ及びレール１５ｂが形成されている。第１の実施の形態に於いては、それぞれのベース部材１の上面に形成されたレールは、略平行に形成されているものとして説明を行ったが、第２の実施の形態に於いては、それぞれのベース部材１の上面に形成されているレール１５ａ及びレール１５ｂは、互いに直交する様に形成されている。すなわち、一方のレール１５ａを一方のベース部材１の長手方向に対して平行に形成し、他方のレール１５ｂを他方のベース部材１の見付方向に対して平行に形成する。 Rails 15a and 15b are formed on the upper surfaces of the two base members 1, respectively. In the first embodiment, the rails formed on the upper surfaces of the respective base members 1 have been described as being substantially parallel to each other. However, in the second embodiment, The rail 15a and the rail 15b formed on the upper surface of each base member 1 are formed to be orthogonal to each other. That is, one rail 15 a is formed in parallel to the longitudinal direction of one base member 1, and the other rail 15 b is formed in parallel to the direction in which the other base member 1 is found.
レール１５ａ及びレール１５ｂを互いに直交する様に形成することによって、第１の実施の形態に係る設備用基礎と同様の効果を得られると共に、上部に載置する設備機器の脚部の幅に関わらず本発明に係る設備用基礎を用いることができる。具体的には、レールを平行に形成した場合、設備機器の脚部の間隔と、２本のレールの間隔が同一であることが必要であったが、レールを互いに直交する様に形成することによって、脚部の間隔に関わらず設備機器を載置することができる。 By forming the rail 15a and the rail 15b so as to be orthogonal to each other, it is possible to obtain the same effect as that of the facility foundation according to the first embodiment, and to relate to the width of the leg of the facility device placed on the upper portion. The equipment foundation according to the present invention can be used. Specifically, when the rails are formed in parallel, it is necessary that the distance between the leg portions of the equipment and the distance between the two rails be the same, but the rails are formed so as to be orthogonal to each other. Thus, the equipment can be placed regardless of the distance between the leg portions.
以下、本発明に係る設備用基礎の第３の実施の形態について詳細な説明をする。第３の実施の形態は、第１の実施の形態乃至第２の実施の形態に係る設備用基礎を施工する方法に関するものである。尚、第３の実施の形態に係る設備用基礎の施工方法の詳細な説明に於いては、説明の便宜上、第１の実施の形態に係る設備用基礎を用いて説明を行うが、第２の実施の形態に係る設備用基礎を用いるものであっても良い。さらに、本実施の形態に於いては、説明の便宜上、土の上に設備用基礎を載置することとするが、例えばコンクリートの地面等に載置するものであっても良い。 Hereinafter, the third embodiment of the foundation for equipment according to the present invention will be described in detail. 3rd Embodiment is related with the method of constructing the foundation for facilities which concerns on 1st Embodiment thru | or 2nd Embodiment. In the detailed description of the construction method for the facility foundation according to the third embodiment, the facility foundation according to the first embodiment will be described for convenience of explanation. The equipment foundation according to the embodiment may be used. Furthermore, in this embodiment, for convenience of explanation, the foundation for equipment is placed on the soil, but it may be placed on concrete ground or the like, for example.
図６は、設備用基礎の施工工程の一部を示す要部斜視図であり、図７は、施工完了後の設備用基礎の断面図である。 FIG. 6 is a perspective view of a principal part showing a part of the construction process of the equipment foundation, and FIG. 7 is a cross-sectional view of the equipment foundation after the construction is completed.
先ず、第１の施工工程として、領域Ｐに所定の大きさ及び深さを有する穴２１を形成する。穴２１は、載置される設備用基礎２０の枠より小さい開口を有するものである。穴２１の深さは例えば開口から７０ｍｍ程度である。 First, as a first construction step, a hole 21 having a predetermined size and depth is formed in the region P. The hole 21 has an opening smaller than the frame of the equipment base 20 to be placed. The depth of the hole 21 is, for example, about 70 mm from the opening.
次に、第２の施工工程として、穴２１を囲う様にして設備用基礎２０を載置する。このとき、設備用基礎２０によって形成される枠内に、穴２１の開口が完全に露出する様に載置されることが好ましい。又、全ての異形鉄筋３は、穴２１の内部に収容される様に載置されることが好ましい。 Next, as a second construction step, the facility foundation 20 is placed so as to surround the hole 21. At this time, it is preferable that the hole 21 is placed in a frame formed by the equipment base 20 so that the opening of the hole 21 is completely exposed. Moreover, it is preferable that all the deformed reinforcing bars 3 are placed so as to be accommodated in the hole 21.
次に、第３の施工工程として、穴２１及び枠によって形成された１つの空間に、生コンクリートを流し込む。 Next, as a third construction step, ready-mixed concrete is poured into one space formed by the hole 21 and the frame.
その後、第１の実施の形態に於いて説明を行った方法で、設備用基礎２０の上部に所定の設備機器を載置する。 Thereafter, predetermined equipment is placed on the upper part of the equipment base 20 by the method described in the first embodiment.
この様な工程によって設備用基礎を形成することによって、コンクリートを領域Ｐを形成する土内部まで流し込む為、より強固な基礎を形成することができる。 By forming the foundation for equipment by such a process, since concrete is poured into the soil forming the region P, a stronger foundation can be formed.
