Description

本発明は、支持器具及びロッドを支持する方法に関する。 The present invention relates to a support device and a method of supporting a rod.

ロッドを対象物に定着させるための定着具が開発されている。特許文献１には、定着具の一例について記載されている。定着具は、ソケット及びウェッジを有している。ソケットは、内壁面を有している。ロッドは、ソケットの内壁面によって囲まれた領域を通過している。ソケットの内壁面は、ソケットの前方に行くほど直径が小さくなるように形成された円錐面をなしている。ウェッジは、ロッドの外周面とソケットの内壁面の間に位置している。ウェッジがソケットの前方に向けて移動することで、ウェッジがロッドの外周面とソケットの内壁面の間に強固に食い込む。これらの作用でロッドへの強い引張力に対し、耐えることが出来る。 Fixing tools have been developed to fix the rod to the object. Patent Document 1 describes an example of a fixing tool. The fixture has a socket and a wedge. The socket has an inner wall surface. The rod passes through an area surrounded by the inner wall of the socket. The inner wall surface of the socket has a conical surface formed so that the diameter becomes smaller toward the front of the socket. The wedge is located between the outer peripheral surface of the rod and the inner wall surface of the socket. As the wedge moves toward the front of the socket, the wedge firmly bites between the outer peripheral surface of the rod and the inner wall surface of the socket. With these actions, it can withstand a strong tensile force on the rod.

For example, the push member 250 may be a bolt, more specifically a perforated bolt. The push member 250 (bolt with a hole) may be screwable into the opening 252.

基材２４０は、第１固定具２１０及び第２固定具２２０が収容部材２３０の空間２３２内に収容された状態で、収容部材２３０に支持器具２０の前後方向に可動に取り付けられている。基材２４０は、取り付け具２６０によって、収容部材２３０に可動に取り付け可能になっている。取り付け具２６０は、ネジ２６０ａ、ナット２６０ｂ及び弾性体２６０ｃを含んでいる。ネジ２６０ａは、基材２４０の前方から、基材２４０の開口２６２、第１固定具２１０の凸部２１４の開口２６４及び収容部材２３０の開口２６６を順に貫通して位置させることができる。ナット２６０ｂは、弾性体２６０ｃが収容部材２３０及びナット２６０ｂの間に位置するように、収容部材２３０の後方からネジ２６０ａに取り付け可能になっている。弾性体２６０ｃの変形によって、基材２４０は、支持器具２０の前後方向に移動することができる。 The base material 240 is movably attached to the housing member 230 in the front-rear direction of the support device 20 in a state where the first fixing tool 210 and the second fixing tool 220 are housed in the space 232 of the housing member 230. The base material 240 can be movably attached to the accommodating member 230 by the attachment 260. The fitting 260 includes a screw 260a, a nut 260b and an elastic body 260c. The screw 260a can be positioned so as to penetrate the opening 262 of the base material 240, the opening 264 of the convex portion 214 of the first fixture 210, and the opening 266 of the accommodating member 230 in this order from the front of the base material 240. The nut 260b can be attached to the screw 260a from the rear of the accommodating member 230 so that the elastic body 260c is located between the accommodating member 230 and the nut 260b. Due to the deformation of the elastic body 260c, the base material 240 can move in the front-rear direction of the support device 20.

弾性体２６０ｃは、コイルスプリングにしてもよい。弾性体２６０ｃ（コイルスプリング）は、ネジ２６０ａの周囲を巻くように位置させることができる。弾性体２６０ｃは、図２に示す例に限定されるものでない。 The elastic body 260c may be a coil spring. The elastic body 260c (coil spring) can be positioned so as to wind around the screw 260a. The elastic body 260c is not limited to the example shown in FIG.

支持器具２０は、複数の取り付け具２６０（例えば、図１及び図２に示すように、２つの取り付け具２６０）を備えていてもよい。取り付け具２６０の数は、図１及び図２に示す例に限定されない。 The support device 20 may include a plurality of attachments 260 (for example, two attachments 260 as shown in FIGS. 1 and 2). The number of fixtures 260 is not limited to the examples shown in FIGS. 1 and 2.

基材２４０は、押し部材２７０によって第１固定具２１０及び第２固定具２２０の前方に向けて移動可能になっている。押し部材２７０は、支持器具２０の前後方向に沿って第１固定具２１０及び第２固定具２２０の前方に向けて基材２４０を押す。押し部材２７０は、収容部材２３０の後方から収容部材２３０の開口２７４を貫通して配置させることができる。言い換えると、収容部材２３０は、押し部材２７０を案内するためのガイドとして機能している。基材２４０を支持器具２０の前方に向けて押すことで、定着具の締め部材（例えば、後述する図５に示す締め部材１２０）を定着具の前方に向けて押し込むことができ、ロッドを締め部材によって締め付けることができる。 The base material 240 is movable toward the front of the first fixture 210 and the second fixture 220 by the push member 270. The pushing member 270 pushes the base material 240 toward the front of the first fixture 210 and the second fixture 220 along the front-rear direction of the support device 20. The push member 270 can be arranged from behind the accommodating member 230 through the opening 274 of the accommodating member 230. In other words, the accommodating member 230 functions as a guide for guiding the pushing member 270. By pushing the base material 240 toward the front of the support device 20, the tightening member of the fixing tool (for example, the tightening member 120 shown in FIG. 5 described later) can be pushed toward the front of the fixing tool, and the rod is tightened. It can be tightened by a member.

基材２４０は、板形状、より具体的には、円板形状にしてもよい。基材２４０の形状は、図２に示す例に限定されない。 The base material 240 may have a plate shape, more specifically, a disk shape. The shape of the base material 240 is not limited to the example shown in FIG.

押し部材２７０は、例えばネジにしてもよい。押し部材２７０（ネジ）をねじ込むことで基材２４０を第１固定具２１０及び第２固定具２２０の前方に向けて押すことができる。 The push member 270 may be, for example, a screw. By screwing the pushing member 270 (screw), the base material 240 can be pushed toward the front of the first fixture 210 and the second fixture 220.

押し部材２７０の先端及び基材２４０の間には、緩衝部材２７２を配置してもよい。押し部材２７０の先端が基材２４０を直接接触すると、基材２４０が押し部材２７０の先端によって損傷するおそれがある。緩衝部材２７２によって、押し部材２７０の先端及び基材２４０の接触による基材２４０の損傷を低減することができる。緩衝部材２７２はなくてもよい。 A cushioning member 272 may be arranged between the tip of the pushing member 270 and the base material 240. If the tip of the pushing member 270 comes into direct contact with the base material 240, the base material 240 may be damaged by the tip of the pushing member 270. The cushioning member 272 can reduce damage to the base material 240 due to contact between the tip of the push member 270 and the base material 240. The cushioning member 272 may be omitted.

支持器具２０は、複数の押し部材２７０（例えば、図１及び図２に示すように、４つの押し部材２７０）を備えていてもよい。複数の押し部材２７０は、実質的に回転対称に配置してもよい。この場合、複数の押し部材２７０によって基材２４０に与えられる力の分布のばらつきを低減することができる。押し部材２７０の数及び配置は、図２に示す例に限定されない。 The support device 20 may include a plurality of push members 270 (for example, four push members 270 as shown in FIGS. 1 and 2). The plurality of push members 270 may be arranged substantially rotationally symmetrically. In this case, it is possible to reduce the variation in the distribution of the force applied to the base material 240 by the plurality of pushing members 270. The number and arrangement of the pushing members 270 are not limited to the example shown in FIG.

押し部材２７０は、収容部材２３０を貫通して配置されていなくてもよい。例えば、押し部材２７０は、収容部材２３０の外側に配置されていてもよい。 The push member 270 may not be arranged so as to penetrate the accommodating member 230. For example, the push member 270 may be arranged outside the accommodating member 230.

The second pushing member 250b pushes the second fixture 220 from a direction different from that of the first pushing member 250a. In the example shown in FIG. 4, the second pushing member 250b pushes the second fixture 220 from the direction opposite to that of the first pushing member 250a. In this way, the push member 250 can be rotated along the direction D1.

押し部材２５０が第２固定具２２０を押す態様は、図４に示す例に限定されない。一例において、単一の押し部材２５０のみによって第２固定具２２０を押してもよい。他の一例において、３つ以上の押し部材２５０によって第２固定具２２０を押してもよい。いずれの例においても、押し部材２５０を方向Ｄ１に沿って回転させることができる。さらに他の一例において、第２押し部材２５０ｂが第２固定具２２０を押す方向は、第１押し部材２５０ａが第２固定具２２０を押す方向に対する逆方向以外の方向であってもよい。 The mode in which the pushing member 250 pushes the second fixture 220 is not limited to the example shown in FIG. In one example, the second fixture 220 may be pushed by only a single push member 250. In another example, the second fixture 220 may be pushed by three or more pushing members 250. In either example, the push member 250 can be rotated along the direction D1. In still another example, the direction in which the second pushing member 250b pushes the second fixture 220 may be a direction other than the direction opposite to the direction in which the first pushing member 250a pushes the second fixture 220.

図３及び図４に示す構成によれば、第２固定具２２０を回転させることで、複数のロッドをそれぞれほぼ等しい力でまとめて締め付けることができる。したがって、定着具に設けられた複数のロッドを簡易に支持することができる。 According to the configurations shown in FIGS. 3 and 4, by rotating the second fixture 220, the plurality of rods can be collectively tightened with substantially the same force. Therefore, it is possible to easily support a plurality of rods provided on the fixing tool.

さらに、図３及び図４に示す構成によれば、複数のロッドを第１固定具２１０及び第２固定具２２０によって締め付けながら、基材２４０（図１及び図２）によって定着具の締め部材（例えば、後述する図５に示す締め部材１２０）を押すことができる。したがって、定着具の前後方向に複数のロッドを揃えながら、締め部材によって複数のロッドを締め付けることができる。 Further, according to the configurations shown in FIGS. 3 and 4, the fixing member (FIG. 1 and FIG. 2) of the fixing tool is used while tightening the plurality of rods by the first fixing tool 210 and the second fixing tool 220. For example, the tightening member 120) shown in FIG. 5 described later can be pressed. Therefore, it is possible to tighten the plurality of rods by the tightening member while aligning the plurality of rods in the front-rear direction of the fixing tool.

図５は、定着具１０に設けられたロッド３０を支持する方法の一例を説明するための図である。 FIG. 5 is a diagram for explaining an example of a method of supporting the rod 30 provided on the fixing tool 10.

まず、図５を用いて定着具１０を説明する。 First, the fixing tool 10 will be described with reference to FIG.

定着具１０は、筒状部材１１０及び複数の締め部材１２０を備えている。 The fixing tool 10 includes a tubular member 110 and a plurality of tightening members 120.

図５は、定着具１０の複数の締め部材１２０が支持器具２０の基材２４０によって筒状部材１１０の前方に向けて押し込まれる前の状態を示している。定着具１０の複数の締め部材１２０を押し込むことで、ロッド３０を複数の締め部材１２０によって締め付けることができ、ロッド３０を定着具１０に固定することができる。 FIG. 5 shows a state before the plurality of tightening members 120 of the fixing tool 10 are pushed toward the front of the tubular member 110 by the base material 240 of the support device 20. By pushing the plurality of tightening members 120 of the fixing tool 10, the rod 30 can be tightened by the plurality of tightening members 120, and the rod 30 can be fixed to the fixing tool 10.

筒状部材１１０は、内側面１１２を有している。筒状部材１１０の内側面１１２は、筒状部材１１０の内部空間を画定している。ロッド３０の軸方向（図５における定着具１０及び支持器具２０の前後方向）に垂直な断面における筒状部材１１０の内部空間の面積は、定着具１０の後方から前方に向かうにつれて減少している。 The tubular member 110 has an inner side surface 112. The inner side surface 112 of the tubular member 110 defines the internal space of the tubular member 110. The area of the internal space of the tubular member 110 in the cross section perpendicular to the axial direction of the rod 30 (the front-rear direction of the fixing tool 10 and the supporting device 20 in FIG. 5) decreases from the rear to the front of the fixing tool 10. ..

筒状部材１１０は、剛性材料（例えば、金属）からなっている。したがって、筒状部材１１０は容易に変形しない。 The tubular member 110 is made of a rigid material (for example, metal). Therefore, the tubular member 110 is not easily deformed.

複数の締め部材１２０は、複数の第１締め部材１２０ａ及び第２締め部材１２０ｂを含んでいる。図５における定着具１０及び支持器具２０の前後方向から見て、複数の第１締め部材１２０ａ（例えば、４つの第１締め部材１２０ａ）は、第２締め部材１２０ｂの周囲に位置している。各第１締め部材１２０ａ及び第２締め部材１２０ｂの間には、ロッド３０が位置している。 The plurality of tightening members 120 include a plurality of first tightening members 120a and a second tightening member 120b. When viewed from the front-rear direction of the fixing tool 10 and the support device 20 in FIG. 5, the plurality of first tightening members 120a (for example, four first tightening members 120a) are located around the second tightening member 120b. A rod 30 is located between the first tightening member 120a and the second tightening member 120b.

図５に示すように、ロッド３０及び第１締め部材１２０ａの間及びロッド３０及び第２締め部材１２０ｂの間には、充填剤１３２が設けられていてもよい。ロッド３０は、充填剤１３２に覆われていてもよい。充填剤１３２は、接着剤として機能してもよい。この場合、充填剤１３２によってロッド３０を第１締め部材１２０ａ及び第２締め部材１２０ｂに接着させることができる。 As shown in FIG. 5, a filler 132 may be provided between the rod 30 and the first tightening member 120a and between the rod 30 and the second tightening member 120b. The rod 30 may be covered with a filler 132. The filler 132 may function as an adhesive. In this case, the filler 132 can bond the rod 30 to the first tightening member 120a and the second tightening member 120b.

第１締め部材１２０ａは、外側面１２２を有している。第１締め部材１２０ａは、外側面１２２が筒状部材１１０の内側面１１２に対向するように位置している。筒状部材１１０の内側面１１２及び第１締め部材１２０ａの外側面１２２の間には、焼き付き防止剤が設けられていてもよい。 The first tightening member 120a has an outer surface 122. The first tightening member 120a is positioned so that the outer surface 122 faces the inner surface 112 of the tubular member 110. An anti-seizure agent may be provided between the inner side surface 112 of the tubular member 110 and the outer surface 122 of the first tightening member 120a.

締め部材１２０は、弾性材料（例えば、樹脂）からなっている。したがって、締め部材１２０は、筒状部材１１０よりも変形しやすい。 The tightening member 120 is made of an elastic material (for example, resin). Therefore, the tightening member 120 is more easily deformed than the tubular member 110.

複数の締め部材１２０が定着具１０の前方に向けて押し込まれると、第１締め部材１２０ａは、筒状部材１１０によって締め付けられる。このようにして、第１締め部材１２０ａからロッド３０に向かう方向に力が加わり、ロッド３０は、締め部材１２０によって締め付けられる。したがって、ロッド３０を定着具１０に強固に固定することができる。 When the plurality of tightening members 120 are pushed toward the front of the fixing tool 10, the first tightening member 120a is tightened by the tubular member 110. In this way, a force is applied in the direction from the first tightening member 120a toward the rod 30, and the rod 30 is tightened by the tightening member 120. Therefore, the rod 30 can be firmly fixed to the fixing tool 10.

次に、ロッド３０を支持する方法及びロッド３０を定着具１０に固定する方法を説明する。 Next, a method of supporting the rod 30 and a method of fixing the rod 30 to the fixing tool 10 will be described.

ロッド３０は、樹脂、例えば、ＦＲＰ（Ｆｉｂｅｒ−ＲｅｉｎｆｏｒｃｅｄＰｌａｓｔｉｃｓ）からなっている。 The rod 30 is made of a resin, for example, FRP (Fiber-Reinforced Plastics).

まず、ロッド３０を定着具１０に設ける。具体的には、複数の締め部材１２０の間（第１締め部材１２０ａ及び第２締め部材１２０ｂの間）にロッド３０を通す。 First, the rod 30 is provided on the fixing tool 10. Specifically, the rod 30 is passed between the plurality of tightening members 120 (between the first tightening member 120a and the second tightening member 120b).

次いで、第１固定具２１０及び第２固定具２２０を一方向（図５における前後方向）に並べて、第１固定具２１０の第１開口２０２及び第２固定具２２０の第２開口２０４にロッド３０を通す。 Next, the first fixture 210 and the second fixture 220 are arranged in one direction (front-rear direction in FIG. 5), and the rod 30 is placed in the first opening 202 of the first fixture 210 and the second opening 204 of the second fixture 220. Through.

ロッド３０を第１固定具２１０の第１開口２０２及び第２固定具２２０の第２開口２０４に通す前にロッド３０をロッド３０の軸方向（図５における前後方向）に引っ張ってもよい。これにより、ロッド３０にプレテンションを与えることができる。ロッド３０は、様々な方法、例えば、油圧、空圧又はガス圧によって引っ張ることができる。ロッド３０を引っ張ることで、ロッド３０の撓みを抑えることができる。 The rod 30 may be pulled in the axial direction of the rod 30 (the front-rear direction in FIG. 5) before passing the rod 30 through the first opening 202 of the first fixture 210 and the second opening 204 of the second fixture 220. As a result, the rod 30 can be pretensioned. The rod 30 can be pulled by various methods, for example hydraulic, pneumatic or gas pressure. By pulling the rod 30, the bending of the rod 30 can be suppressed.

次いで、第２固定具２２０を第１位置（図３）から第２位置（図４）にかけて、方向Ｄ１（図４）に沿って回転させる。 Next, the second fixture 220 is rotated along the direction D1 (FIG. 4) from the first position (FIG. 3) to the second position (FIG. 4).

このようにして、ロッド３０を支持器具２０によって支持することができる。 In this way, the rod 30 can be supported by the support device 20.

次いで、支持器具２０の基材２４０によって定着具１０の複数の締め部材１２０を押す。複数の締め部材１２０が定着具１０の前方に向けて移動すると、ロッド３０が複数の締め部材１２０によって締め付けられる。 Next, the base material 240 of the support device 20 pushes the plurality of tightening members 120 of the fixing tool 10. When the plurality of tightening members 120 move toward the front of the fixing tool 10, the rod 30 is tightened by the plurality of tightening members 120.

このようにして、ロッド３０を定着具１０に固定することができる。 In this way, the rod 30 can be fixed to the fixing tool 10.

ロッド３０を定着具１０に固定した後、支持器具２０は、取り外してもよい。 After fixing the rod 30 to the fixing tool 10, the support device 20 may be removed.

上述した方法によれば、定着具１０に設けられたロッド３０を支持器具２０によって簡易に支持することができる。 According to the method described above, the rod 30 provided on the fixing tool 10 can be easily supported by the support device 20.

さらに、上述した方法によれば、支持器具２０によって定着具１０の前後方向に複数のロッド３０を揃えながら、複数の締め部材１２０によって複数のロッド３０を締め付けることができる。 Further, according to the method described above, the plurality of rods 30 can be tightened by the plurality of tightening members 120 while the plurality of rods 30 are aligned in the front-rear direction of the fixing tool 10 by the support device 20.

図６は、図４の変形例を示す図である。 FIG. 6 is a diagram showing a modified example of FIG.

支持器具２０は、加圧器３５０を備えていてもよい。加圧器３５０は、第２固定具２２０が回転するように、第２固定具２２０を加圧することができる。図６に示す例において、加圧器３５０は、第２固定具２２０の第１面２２２ａ及び第２面２２２ｂを加圧している。 The support device 20 may include a pressurizer 350. The pressurizer 350 can pressurize the second fixture 220 so that the second fixture 220 rotates. In the example shown in FIG. 6, the pressurizer 350 pressurizes the first surface 222a and the second surface 222b of the second fixture 220.

加圧器３５０は、第２固定具２２０を加圧するための様々な装置を含んでいてもよく、例えば、油圧発生器、空圧発生器又はガス圧発生器を含んでいてもよい。例えば、第２固定具２２０に大きな圧力を加える必要がある場合、加圧器３５０は、油圧発生器を含んでいてもよい。 The pressurizer 350 may include various devices for pressurizing the second fixture 220, and may include, for example, a hydraulic pressure generator, a pneumatic generator or a gas pressure generator. For example, if a large pressure needs to be applied to the second fixture 220, the pressurizer 350 may include a hydraulic pressure generator.

以上、図面を参照して本発明の実施形態について述べたが、これらは本発明の例示であり、上記以外の様々な構成を採用することもできる。 Although the embodiments of the present invention have been described above with reference to the drawings, these are examples of the present invention, and various configurations other than the above can be adopted.
