Description

[Technical field]

[0001] The present invention relates to a rod-shaped body clamping device that is used to clamp a portion of a rod-shaped body, such as a hanging bolt shaft, in the axial direction to attach itself or another member to the rod-shaped body or to hold the rod-shaped body.

[0002] First, several "technical terms" used in this specification that are not considered to be "general technical terms" are defined. "Screwed" means that the thread of the male screw member and the root of the female screw member are locked together, and the male screw and female screw members are connected to each other. "Screwed" and "retracted" mean that when the male screw member and the female screw member are rotated relative to each other in a screwed state, the two members move closer to each other, while the two members move farther away from each other, and "screwed" is a compound term made up of "screwed" and "retracted". Furthermore, "screwed rotation" means that at least one of the male screw member and the female screw member that are screwed together is rotated. [Background technology]

[0003] Patent Document 1 discloses a rod-shaped body clamp that can be attached to a hanging bolt shaft and is used to install and fix various installation objects to the hanging bolt shaft or to fix the end of the hanging bolt shaft to a wall surface, etc., but the rod-shaped body clamp is designed to be capable of clamping only a bolt shaft with one specific type of outer diameter.

[0004] The majority of bolt shafts used as suspension bolt shafts, etc. have a diameter of 3 / 8 inch or 1 / 2 inch, and bolt shafts of other diameters are also sometimes used. The rod-shaped body clamping tool in Patent Document 1 can only clamp one type of bolt shaft with a specific outer diameter, so for bolt shafts with a different outer diameter, it was necessary to prepare a different rod-shaped body clamping tool corresponding to the different outer diameter.

[0005] In addition, the rod-shaped body clamping device disclosed in Patent Document 1 has a rectangular attachment plate for fixing to various installation bodies or wall surfaces, and when clamped (attached) to the suspension bolt shaft, the arrangement direction of the attachment plate with respect to the suspension bolt shaft is mutually perpendicular and invariable. Therefore, it is not possible to accommodate changes in the arrangement direction of the attachment plate with respect to the suspension bolt shaft, and it is necessary to prepare a separate rod-shaped body clamping device with an attachment plate that can be arranged in a different direction with respect to the suspension bolt shaft.

[0006] On the other hand, as shown in Patent Document 2, there are also bolt shafts that are installed parallel to a ceiling surface or a side wall surface, and in order to fix bolt shafts with different installation directions to the ceiling surface, etc., it was necessary to prepare multiple rod-shaped body clamping devices with different arrangement directions of the attachment plate portion.

[0007] [Patent Document 1] JP 2022-30353 A [Patent Document 2] JP 2020-156251 A Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention has an objective of providing a rod-shaped body clamping device that clamps a rod-shaped body to attach other members thereto or holds the rod-shaped body, and that can be used for rod-shaped bodies of different diameters or orientations. [Means for solving the problem]

[0009] The invention of claim 1 to solve the above problem is as follows: A rod-shaped body clamping device comprising a first member having a first threaded portion and a second member having a second threaded portion that can be screwed into the first threaded portion, the first and second members being screwed together to clamp a rod-shaped body disposed between the first and second members, The first member has a plurality of upright portions whose upright direction is the screw advance / retract direction with respect to the second member, and between the plurality of upright portions, one or a plurality of rod-shaped body arrangement spaces are formed in which one rod-shaped body can be arranged with an axial direction intersecting with the upright direction of the upright portions, and the first screw portion is composed of a screw groove formed discontinuously across the plurality of upright portions, the second member includes a pressing body that moves integrally with the second member in response to the screwing movement of the second member in a relatively free-wheeling state without following the screwing rotation of the second member when the second member screw-retracts relative to the first member, and a clamping portion provided on the first member and the pressing body moved by the screwing movement of the second member can clamp a rod-shaped body arranged in the rod-shaped body arrangement space; one or more rod-shaped body arrangement spaces are provided so that both of the two types of rod-shaped bodies, large diameter and small diameter, can be clamped; When there is one rod-shaped body arrangement space, it is possible to select and arrange either a large-diameter rod-shaped body or a small-diameter rod-shaped body, When the rod-shaped body arrangement spaces intersect with each other, it is possible to select and arrange either a large-diameter rod-shaped body or a small-diameter rod-shaped body in different rod-shaped body arrangement spaces, or it is possible to select and arrange either a large-diameter rod-shaped body or a small-diameter rod-shaped body in the same rod-shaped body arrangement space, The rod-shaped body arranged in the rod-shaped body arrangement space is held in a clamped state between the clamping portion of the first member and the pressing body provided on the second member due to the relative screwing movement between the first member and the second member.

[0010] According to the invention of claim 1, when there is one rod-shaped body arranging space, either a rod-shaped body having a large diameter or a rod-shaped body having a small diameter is selected and placed therein. When there are a plurality of rod-shaped body arranging spaces intersecting with each other, either a rod-shaped body having a large diameter or a rod-shaped body having a small diameter is selected and placed in different rod-shaped body arranging spaces, or either a rod-shaped body having a large diameter or a rod-shaped body having a small diameter is selected and placed in the same rod-shaped body arranging space. The first threaded portion of the first member consists of a discontinuous screw groove formed across multiple upright portions, and when the first threaded portion and the second threaded portion of the second member are screwed together and the first and second members screw forward relative to each other, the pressing body, which rotates freely relative to the second member and moves together with the second member in response to the screw forward and backward movement of the second member, and the clamping portion of the first member are relatively close to each other, and the pressing body presses the rod-shaped body arranged in the rod-shaped body arrangement space of the first member, and the rod-shaped body is held in a pressed state between the pressing body provided on the second member and the clamping portion of the first member.

[0011] Therefore, according to the invention of claim 1, a plurality of types of rod-shaped bodies with different outer diameters can be clamped by the same rod-shaped body clamping tool by selecting and arranging rod-shaped bodies with large or small diameters in the same rod-shaped body arranging space, or by selecting and arranging rod-shaped bodies with large and small diameters in a plurality of rod-shaped body arranging spaces that intersect with each other. Also, when a plurality of rod-shaped body arranging spaces that intersect with each other are formed in the first member, it is possible to clamp the rod-shaped bodies with different arrangement directions relative to the rod-shaped body clamping tool by arranging the rod-shaped bodies in different rod-shaped body arranging spaces.

[0012] The invention of claim 2 is characterized in that, in the invention of claim 1, at least one of the one or more rod-shaped body arrangement spaces is continuously formed with a large diameter clamping portion having an arc-shaped cross-section that follows the outer surface of the large diameter rod-shaped body, and a small diameter clamping portion having an arc-shaped cross-section that follows the outer surface of the small diameter rod-shaped body, forward of the large diameter clamping portion along the screw-on direction of the second member.

[0013] According to the invention of claim 2, in at least one of the one or more rod-shaped body arrangement spaces, a large diameter clamping portion having an arc-shaped cross-section along the outer surface of the large diameter rod-shaped body and a small diameter clamping portion having an arc-shaped cross-section along the outer surface of the small diameter rod-shaped body are formed in this order along the screwing direction of the second member relative to the first member, so that large and small diameter rod-shaped bodies can be stably held in the same rod-shaped body arrangement space without being misaligned in the radial direction.

[0014] The invention of claim 3 is the invention of claim 1 or 2, wherein the pressing body has a large diameter pressing surface and a small diameter pressing surface for pressing the large diameter rod-like body or the small diameter rod-like body arranged in the rod-like body arrangement space of the first member, the large diameter pressing surface and the small diameter pressing surface are provided so as to cross each other and extend along the axial direction of each rod-like body, A feature of this embodiment is that it is possible to select whether the large diameter or small diameter pressing surface of the pressing body is used to press a large or small diameter rod-shaped body placed in the rod-shaped body placement space of the first member.

[0015] In the invention of claim 3, the pressing body is rotatable relative to the second member and is connected to the second member so as to be able to move integrally with the second member in the screw-forward and backward directions. The pressing body has a large diameter pressing surface and a small diameter pressing surface which press a large diameter rod-shaped body or a small diameter rod-shaped body arranged in the rod-shaped body arrangement space of the first member, and these surfaces extend along the axial direction of each rod-shaped body, crossing each other. Therefore, by selecting either the large diameter pressing surface or the small diameter pressing surface of the pressing body in accordance with the diameter of the rod-shaped body arranged in the rod-shaped body arrangement space of the first member, the rod-shaped body arranged in the rod-shaped body arrangement space of the first member is clamped between the clamping portion of the first member and the pressing body of the second member regardless of its diameter.

[0016] The invention of claim 4 is characterized in that, in the invention of claim 3, the large diameter pressing surface and the small diameter pressing surface of the pressing body can be selected or changed only when the first member and the second member are released from the screw engagement.

[0017] According to the invention of claim 4, only when the screw engagement between the first member and the second member is released, i.e., only when the first member and the second member are disassembled, can the pressing body connected to the second member be allowed to rotate freely relative to the second member, thereby making it possible to select and change the respective positions of the large diameter pressing surface and the small diameter pressing surface of the pressing body relative to the first member. Therefore, after carefully checking the diameter of the rod-shaped body placed in the rod-shaped body arrangement space of the first member, either the large diameter pressing surface or the small diameter pressing surface of the pressing body corresponding to the diameter of the rod-shaped body is selected, and with the position of the pressing body in the free-wheeling direction corrected so that the selected large diameter or small diameter pressing surface is positioned directly above the rod-shaped body arranged in the rod-shaped body arrangement space of the first member, the first threaded portion of the first member and the second threaded portion of the second member are screwed together, and the first and second members are screwed forward relatively, so that the rod-shaped body is clamped between the large diameter or small diameter pressing surface of the pressing body corresponding to the diameter of the rod-shaped body arranged in the rod-shaped body arrangement space of the first member and the clamping portion of the first member.

[0018] The invention of claim 5 is characterized in that in the invention of claim 3, the pressing body has a use inhibiting portion that inhibits use of the large diameter pressing surface.

[0019] One type of rod-shaped body is a bolt shaft, and the majority of these bolt shafts have a diameter of 3 / 8 inch (3 / 8 inch) or 4 / 2 inch (1 / 2 inch), with 3 / 4 inch bolt shafts being used more frequently than 4 / 4 inch bolt shafts. For this reason, in the invention of claim 5, if a use inhibiting section is provided on the large diameter pressing surface of the pressing body corresponding to the 4 / 4 bolt shaft, which is a large diameter rod-shaped body that is used less frequently, the reflex effect will be that the small diameter pressing surface, which is used more frequently, will inevitably be used, and this will prevent mistakes in selecting the large and small diameter pressing surfaces provided on the pressing body at the construction site, improving construction efficiency.

[0020] The invention of claim 6 is characterized in that in the invention of claim 1 or 2, at least one of the clamping portion and the pressing body has an arc-shaped small diameter pressing surface that fits along the outer surface of the small diameter rod-shaped body.

[0021] According to the invention of claim 6, at least one of the clamping part and the pressing body has an arc-shaped small diameter pressing surface along the outer surface of the small diameter rod-like body, so that when the clamping part of the rod-like body arrangement space of the first member and the pressing body connected to the second member are in a state of preparation for clamping the small diameter rod-like body, a part of the outer peripheral surface of the circular cross section of the small diameter rod-like body is partially fitted into the arc-shaped small diameter pressing surface provided on at least one of the clamping part and the pressing body, so that the small diameter rod-like body is prevented from moving in the radial direction. As a result, the clamping state of the small diameter rod-like body by the clamping part of the first member and the pressing body of the second member is stabilized. The reason why the small diameter pressing surface is selected is that the small diameter rod-like body is used more frequently than the large diameter rod-like body.

[0022] The invention of claim 7 is characterized in that, in the invention of claim 1 or 2, the first member has a regulating portion that abuts against the upright portion in the upright direction or from both sides of the rod-shaped body while one of the large diameter rod-shaped body or the small diameter rod-shaped body is clamped between the clamping portion and the pressing body, thereby regulating radial movement of the rod-shaped body.

[0023] According to the invention of claim 7, when a large diameter rod-shaped body or a small diameter rod-shaped body is clamped, a regulating portion is provided that abuts against the rod-shaped body in the upright direction of the upright portion or from both sides of the rod-shaped body to regulate radial movement of the rod-shaped body. Therefore, the rod-shaped body is clamped between the clamping portion of the first member and the pressing body of the second member in a state in which radial movement is restricted, thereby stabilizing the clamped state.

[0024] The invention of claim 8 is the invention of claim 1 or 2, wherein the rod-shaped body arrangement space is formed by intersecting two or more rods so that the rod-shaped body can be clamped by any of the large diameter rods and the small diameter rods extending in different axial directions in an arranged state, The at least two rod-shaped body arranging spaces are characterized in that they are positioned on the screw rotation axes of the first threaded portion and the second threaded portion.

[0025] According to the invention of claim 8, since two or more rod-shaped body arrangement spaces are formed to intersect, the rod-shaped body clamping tool can clamp the rod-shaped body in different arrangement positions. Furthermore, since at least two of the rod-shaped body arrangement spaces are located on the screw rotation axis of the first threaded portion and the second threaded portion, a clamping force (pressing force) acts directly on the rod-shaped body, so that the clamped state of the rod-shaped body is stabilized.

[0026] The invention of claim 9 is a rod-shaped body clamping tool comprising a first member having a first threaded portion and a second member having a second threaded portion that can be screwed into the first threaded portion, the first and second members being screwed together to clamp a rod-shaped body disposed between the first and second members, The first member has a plurality of upright portions whose upright direction is the screw advance / retract direction with respect to the second member, and one or more rod-shaped body arrangement spaces are formed between the plurality of upright portions in which the rod-shaped body can be arranged with an axial direction intersecting the upright direction of the upright portions, and the first screw portion is composed of a screw groove formed discontinuously across the plurality of upright portions, the second member includes a pressing body that moves integrally with the second member in response to the screwing movement of the second member in a relatively free-wheeling state without following the screwing rotation of the second member when the second member screw-retracts relative to the first member, and a clamping portion provided on the first member and the pressing body moved by the screwing movement of the second member can clamp a rod-shaped body arranged in the rod-shaped body arrangement space; The rod-shaped body arrangement space is characterized in that two or more rod-shaped body arrangement spaces are formed so that the rod-shaped bodies can be arranged in any arrangement state in at least two directions in which the axial directions intersect.

[0027] According to the invention of claim 9, the position of the rod-shaped body holder relative to the rod-shaped body can be changed by selecting the rod-shaped body arrangement space in which the rod-shaped body is arranged.

[0028] The invention of claim 10 is the invention of any one of claims 1, 2 or 9, wherein the first member has a pair of support arms extending in opposite directions to form a fixing portion to which another member is fixed, The device is characterized in that two rod-shaped body arrangement spaces are formed so that the rod-shaped body can be attached thereto with the direction in which the pair of support arms extend and two different directions that intersect with this direction as the axial direction of the rod-shaped body.

[0029] According to the invention of claim 10, by selecting a plurality of rod-shaped body arrangement spaces, arranging the rod-shaped body, and attaching a rod-shaped body clamping device to the rod-shaped body, it is possible to arrange a pair of support arms parallel to the rod-shaped body or to arrange them crosswise. Effect of the Invention

[0030] According to the present invention, by selecting and placing rod-shaped bodies of large or small diameter in the same rod-shaped body arrangement space, or by selecting and placing large and small diameter rod-shaped bodies in multiple intersecting rod-shaped body arrangement spaces, it becomes possible to clamp multiple types of rod-shaped bodies with different outer diameters using the same rod-shaped body clamping device, and when multiple intersecting rod-shaped body arrangement spaces are formed in the first member, it becomes possible to clamp the rod-shaped bodies in different arrangement directions relative to the rod-shaped body clamping device by placing the rod-shaped bodies in different rod-shaped body arrangement spaces.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] The present invention will be described in more detail below with reference to the best embodiment. Figures 1 to 8 show the case where a small diameter bolt shaft B1 of 3 is fixed vertically to a fixed plate E using a rod-shaped body clamping tool A. The rod-shaped body clamping tool A is characterized in that it can select and clamp either one of the small diameter and large diameter bolt shafts B1, B2 of 3 and 4 different outer diameters, and also select and clamp one of two mutually orthogonal directions (mostly two directions, vertical and horizontal) with respect to the arrangement direction of the small diameter and large diameter bolt shafts B1, B2. The rod-shaped body clamping device A is composed of a holding member S that holds each bolt shaft B1, B2, and a female threaded cap member F that is screwed into the holding member S, and a pressing member P for pressing the small diameter or large diameter bolt shaft B1, B2 held by the holding member S against the holding member S is connected to the female threaded cap member F so that it can rotate freely without following the screw rotation of the female threaded cap member F when the female threaded cap member F is screwed into the holding member S.

[0033] 2, the retaining member S has a total of four male threaded portions 2 separated from one another and erected at regular intervals in the circumferential direction in the longitudinal center of a rectangular thick plate-shaped base 1, and first and second bolt shaft arrangement spaces 3, 4 are formed along mutually perpendicular directions between adjacent male threaded portions 2. That is, the first and second bolt shaft arrangement spaces 3, 4 are spaces for respectively arranging small and large diameter bolt shafts B1, B2 in the vertical and horizontal directions, and are formed along the width and longitudinal directions of the rectangular thick plate-shaped base 1, respectively. The four male thread portions 2 are formed from four remaining portions by removing solid portions from a solid cylinder to form the first and second bolt shaft arrangement spaces 3, 4, and therefore the outer circumferential surface of each male thread portion 2 is formed as an interrupted curved surface having a circular cross section centered on the screw rotation axis C [see Figs. 1, 3(b), 4 and 13], and a trapezoidal male thread portion 5 is formed in a discontinuous manner on the outer circumferential surface to be screwed into a trapezoidal female thread portion 21 formed on the inner circumferential surface of a housing portion 22 of a cap-shaped female thread cap member F described later. The four male thread portions 2 are formed integrally with the upper surface of a divided base portion 6 formed in the longitudinal center of the base 1 across the entire width, and the first and second bolt shaft arrangement spaces 3, 4 are also formed in the divided base portion 6.

[0034] As shown in Figures 1, 2 and 16, the female thread cap member F comprises a short cylindrical accommodating portion 22 having a trapezoidal female thread portion 21 formed on its inner surface which screws into the trapezoidal male thread portion 5 formed on the outer circumferential surface of each male thread standing portion 2 of the retaining member S, and a top plate portion 23 formed integrally and continuously with one axial end of the accommodating portion 22, with the portion opposite the top plate portion 23 being open.

[0035] As shown in Figures 2, 3, 14 and 17, the pressing member P is integrally formed with an accommodated portion 31 that is accommodated in the accommodating portion 22 of the female thread cap member F and a pressed female thread portion forming portion 32 that is exposed from the accommodating portion 22 of the female thread cap member F in the accommodated state, and a divided holding member arrangement space 33 is formed on the sides of the integrally formed accommodated portion 31 and the pressed female thread portion forming portion 32 over the entire height to enable arrangement of each male thread standing portion 2 and each divided base portion 6 of the holding member S that is divided into four parts along the circumferential direction, so that as shown in Figures 14 and 17, each shape when viewed from above and from the bottom is cross-shaped. In the press female thread forming portion 32 of the pressing member P, a small diameter press female thread portion 34 and a large diameter press female thread portion 35 are formed perpendicular to each other in a state where the female thread tube is split in half in a cross-sectional view, and in a state where the pressing member P is connected to the female thread cap member F, the large diameter press female thread portion 35 on the side closer to the female thread cap member F is formed continuously over the entire axial length, while the small diameter press female thread portion 34 on the side farther from the female thread cap member F is formed in a state where the central portion in the axial direction is missing. On the surfaces corresponding to the half-split surfaces of the small diameter press female thread portion 34 and the large diameter press female thread portion 35, two pairs are arranged opposite each other at both ends of each half-split female thread portion, sandwiching the half-split female thread portion, so that a total of eight positioning projections 36, 37 are projected from the half-split surfaces of the half-split female thread portions (see Figs. 2 and 17). The positioning protrusions 36, 37 are formed on the half surfaces of the small diameter press female thread portion 34 and the large diameter press female thread portion 35. The total of eight positioning protrusions 36, 37 are on the same circumference with respect to the screw rotation axis C of the female thread cap member F, and the positions of the protruding tips are arranged at the same position along the screw rotation axis C.With this structure, the trapezoidal male thread portion 5 of each male thread standing portion 2 of the holding member S is screwed into the trapezoidal female thread portion 21 of the female thread cap member F, and as the female thread cap member F rotates to screw forward relative to the holding member S, before the pressing member P reaches the forward end, the total of eight positioning protrusions 36, 37 of the pressing member P engage with the total of eight positioning recesses 11, 12 formed in the holding member S at positions corresponding to the total of eight positioning protrusions 36, 37 of the pressing member P [see Figures 9(b) and 10(a)], so that the pressing member P can be positioned in two different positions obtained by rotating the pressing member P by 90° relative to the holding member S.

[0036] Each of the three components, the retaining member S, the female screw cap member F and the pressing member P, is formed by injection molding of resin, and the general relationship between each of the three components is as described above. Below, we will explain in detail each of the components S, F and P, focusing on the parts not described above.

[0037] In the retaining member S, first and second bolt shaft arrangement spaces 3, 4 are formed between adjacent male thread standing portions 2 so as to be perpendicular to each other, and a small diameter clamping portion 7a (7b) and a large diameter clamping portion 8a (8b) having a partially arc-shaped cross section are continuously formed at the bottom of each bolt shaft arrangement space 3, 4, so that a circumferential portion of each of the small diameter and large diameter bolt shafts B1, B2 of thirds and fourths can be arranged in a partially fitted state. That is, the small diameter clamping portion 7a (7b) is formed at the bottommost portion of each of the first and second bolt shaft arrangement spaces 3, 4 so as to have a semicircular arc-shaped cross section, and the large diameter clamping portion 8a (8b) is formed so as to be continuous with the small diameter clamping portion 7a (7b) and to have a separated arc-shaped cross section at a position spaced from the bottommost portion, and is divided into two. The small diameter clamping portion 7a formed in the first bolt shaft arranging space 3 and the small diameter clamping portion 7b formed in the second bolt shaft arranging space 4 are formed at the same position in the direction along the screw rotation axis C of the female thread cap member F. Similarly, the large diameter clamping portion 8a formed in the first bolt shaft arranging space 3 and the large diameter clamping portion 8b formed in the second bolt shaft arranging space 4 are also formed at the same position in the direction along the screw rotation axis C of the female thread cap member F. In this way, by allowing either one of the small diameter bolt shafts B1, B2 and the large diameter bolt shafts B2 to be selectively arranged at the bottoms of the first and second bolt shaft arranging spaces 3, 4 arranged orthogonally to each other, it is possible to hold two types of bolt shafts B1, B2 of small diameter and large diameter by the same rod-shaped body clamping tool A. In addition, the arrangement direction of each bolt shaft B1, B2 can be selected and held in either one of two mutually perpendicular directions.

[0038] In order to hold the small or large diameter bolt shafts B1, B2 with the holding member S and the pressing member P connected to the female thread cap member F so as to be rotatable freely, the bolt shafts B1, B2 held by the small diameter clamping portion 7a (7b) or the large diameter clamping portion 8a (8b) of the holding member S are pressed by the small diameter pressing female thread portion 34 or the large diameter pressing female thread portion 35 of the pressing member P. As shown in Figs. 5(b) and 9, on the end faces of the holding member S facing the mutually orthogonal large diameter clamping portions 8a, 8b, two pairs are formed, one pair being a set, at both ends in the axial direction in a state in which the large diameter clamping portions 8a, 8b are sandwiched between the large diameter clamping portions 8a, 8b, corresponding to the total of eight positioning protrusions 36, 37 of the pressing member P, so that a total of eight positioning recesses 11, 12 into which the total of eight positioning protrusions 36, 37 are inserted and fitted are formed.

[0039] A total of four arc-shaped upper end surfaces 6a remain on the outside of the lower end of each male thread standing portion 2 at the upper end of the divided base portion 6 of the holding member S, and as shown in Figure 10 (a) , when the trapezoidal female thread portion 21 of the female thread cap member F is screwed into each trapezoidal male thread portion 5 of each male thread standing portion 2 of the holding member S, and the female thread cap member F is screwed into the holding member S, the open side end face 22a of the accommodating portion 22 of the female thread cap member F approaches the upper end face 6a, and is pressed by the open side end face 22a, thereby determining the screwing end of the female thread cap member F and preventing the screwing from loosening, a pressurized protrusion 13 for preventing loosening is formed along the width direction of the base 1. A similar pair of anti-loosening pressed projections 24 (see FIG. 16(a)) are also formed on the open end surface 22a of the accommodating portion 22 of the female screw cap member F. Here, when the anti-loosening pressed projection 13 goes over the anti-loosening pressed projection 24 by screwing, a clicking sensation is obtained due to the resistance, and it is possible to understand (sense) that the locking has been moved to the tightening completion position, and insufficient tightening of the female screw cap member F can be prevented. In addition, the upper end surface 6a of the portion of the holding member S where one of the pair of anti-loosening pressed projections 13 is formed is extended in the longitudinal direction of the base 1 to form a base extension portion 14, and the upper end surface of the base extension portion 14 is formed with a screw pilot hole 15 into which a reverse rotation prevention screw 71 (see FIG. 1) is screwed to prevent the female screw cap member F from rotating in the retracting direction due to loosening due to loosening when the female screw cap member F is screwed into the holding member S to the maximum extent. In addition, in the base 1 of the holding member S, a large number of elongated screw through holes 16 are formed along the longitudinal direction of the base 1 at predetermined intervals along both the longitudinal direction and the width direction of the base 1.

[0040] Therefore, when viewed in a plane as shown in Figure 10(a), the retaining member S has a shape symmetrical with respect to each axis of the small diameter bolt shaft B1 arranged in the small diameter clamping portions 7a, 7b of the first and second bolt shaft arrangement spaces 3, 4, except for the base extension portion 14 and the pair of anti-loosening pressure-receiving protrusions 13.

[0041] As shown in Figures 13 to 16, in order to connect the pressing member P to the female thread cap member F so that the pressing member P can rotate freely while the accommodated portion 31 of the pressing member P is accommodated inside the accommodating portion 22 of the female thread cap member F, a stepped engagement hole 25 is formed in the center of the top plate portion 23 of the female thread cap member F for engaging with an engagement ring body 38 formed on the upper end of the accommodated portion 31 of the pressing member P. Two pairs of fingertip hook plates 26 are formed on opposing portions of the outer circumferential surface of the accommodating section 22 of the female thread cap member F, for hooking a person's fingertips to increase the rotational force when the female thread cap member F is screwed into the holding member S, and two adjacent fingertip hook plates 26 are connected by a connecting plate 27 having the open end face 22a and the back surface flush with each other, and a number of anti-slip ridges 28 are formed between adjacent fingertip hook plates 26 on the outer circumferential surface of the accommodating section 22 in the axial direction of the accommodating section 22. The fingertip hook plates 26 abut against the head of the reverse rotation prevention screw 71 screwed into the screw pilot hole 15 of the base extension section 14 of the holding member S, thereby preventing the female thread cap member F from loosening.

[0042] 12 to 15 and 17, a total of four divided holding member arrangement spaces 33 are formed on the sides of the pressing member P so that the male thread standing portions 2 and the divided base portions 6 of the holding member S can be arranged in a housed state, and the pressing member P has a cross shape in both plan and bottom views, and is composed of an accommodated portion 31 accommodated in the accommodation portion 22 of the female thread cap member F and a pressing female thread portion forming portion 32 arranged exposed to the accommodation portion 22. The small diameter and large diameter pressing female thread portions 34, 35 are formed in a split state opening on the lower surfaces of the small diameter and large diameter female thread forming block portions 41, 42 arranged orthogonally to each other on the surface of the accommodated portion 31 opposite to the engagement ring body 38. The small diameter press female thread portion 34 is formed in a state of protruding downward from the small diameter female thread forming block portion 41, while the large diameter press female thread portion 35 is formed inside the large diameter female thread forming block portion 42. The reason why the small diameter and large diameter press female thread portions 34, 35 formed in the pressing member P are arranged at different positions along the screw rotation axis C of the female thread cap member F is to enable small and large diameter bolt shafts B1, B2 with different outer diameters to be arranged in the first and second bolt shaft arrangement spaces 3, 4, respectively, and to enable the same pressing member P to press the bolt shafts B1, B2 with different outer diameters.

[0043] That is, as shown in Fig. 7(a), the apexes of the small diameter bolt shaft B1 arranged in the small diameter clamping portion 7a (7b) and the large diameter bolt shaft B2 arranged in the large diameter clamping portion 8a (8b) of the same first or second bolt shaft arranging space 3, 4 have a difference in distance (H0) along the direction of the screw rotation axis C of the female thread cap member F. Correspondingly, the small diameter press female thread portion 34 and the large diameter press female thread portion 35 formed in the small diameter and large diameter female thread forming block portions 41, 42 are formed at positions where the small diameter press female thread portion 34 is formed downward in the height direction by the distance (H0) relative to the large diameter press female thread portion 35, so that the small diameter and large diameter bolt shafts B1 and B2 arranged in the same first or second bolt shaft arranging space 3, 4 can be pressed by the same pressing member P.

[0044] Another major feature of the present invention is that it is possible to grip two types of bolt shafts B1, B2 with different outer diameters by the same rod-shaped body clamping tool A, and therefore the installer must select the circumferential position of the pressing member P relative to the holding member S according to the small-diameter and large-diameter bolt shafts B1, B2 to be clamped. On the other hand, the frequency of use of the 3 / 10 and 4 / 10 bolt shafts B1, B2 is much higher than that of the 4 / 10 large-diameter bolt shaft B2. Therefore, when the 3 / 10 small-diameter bolt shaft B1 is placed in the holding member S, only the small-diameter pressing female thread portion 34 of the pressing member P corresponding to the 3 / 10 small-diameter bolt shaft B1 is selected and used, and when the large-diameter pressing female thread portion 35 is mistakenly selected, the pressing member P cannot be set on the holding member S. That is, the use inhibiting rod portion 43 is erected at the axial end of the large diameter press female thread portion 35 in the large diameter female thread forming block portion 42 of the pressing member P so as to enter the female thread space portion. Therefore, when the large diameter press female thread portion 35 of the pressing member P is set to the holding member S in which the small diameter bolt shaft B1 of 3 is arranged, the use inhibiting rod portion 43 becomes an obstacle and the setting is impossible. At this point, the installer realizes that the selection of the small diameter press female thread portion 34 and the large diameter press female thread portion 35 is incorrect, and rotates the pressing member P by 90° relative to the holding member S and resets it. In addition, since the use inhibiting rod portion 43 can be broken off, when the large diameter press female thread portion 35 of the pressing member P is necessary to clamp the large diameter bolt shaft B2 of 4, the use inhibiting rod portion 43 is broken off.

[0045] In addition, when the rod-shaped body to be clamped is a bolt shaft, as shown in Fig. 4, in a state where the bolt shaft is clamped between the holding member S and the pressing member P, the male threads of the clamping portion of the bolt shafts B1, B2 along the circumferential direction are partially screwed with the female threads of the small-diameter and large-diameter pressing female threads 34, 35 of the pressing member P, so that the clamped bolt shafts B1, B2 do not shift in the axial direction, but if the clamping pressure is insufficient, there is a risk that the bolt shafts B1, B2 may rotate with respect to the rod-shaped body clamping tool A. For this reason, as shown in Fig. 15, a stepped screw through hole 44 penetrating the large-diameter pressing female thread 35 is formed in the center of the accommodated portion 31 of the pressing member P, and the rotation prevention pressing screw 72 (see Fig. 6) inserted into the screw through hole 44 presses the surfaces of both the small-diameter and large-diameter bolt shafts B1, B2 to prevent their rotation. Since the small diameter press female thread portion 34 has its center missing, the anti-rotation press screw 72 inserted into the screw-through hole 44 can press against the surface of the small diameter bolt shaft B1 held in the small diameter press female thread portion 34 through the missing portion.

[0046] Next, with reference to Figs. 1 to 8, a case will be described in which the rod-shaped body clamping tool A is used to clamp and fix a third small diameter bolt shaft B1 to a fixed plate E while maintaining the verticality. First, as shown in Fig. 2, the rectangular base 1 of the holding member S is arranged horizontally or vertically and fixed to the fixed plate E via a plurality of fixing screws 73. In the example of Fig. 2, the base 1 is arranged horizontally, but if there are obstacles on both sides, even if the base 1 is arranged vertically, the third small diameter clamping portion 7b formed at the bottom of the second bolt shaft arrangement space 4 will be arranged vertically, so that the third small diameter bolt shaft B1 can be arranged vertically. In this state, as shown in the left half of Figures 3 and 7(a), when the small diameter bolt shaft B1 is set in the small diameter clamping portion 7a at the bottom of the first bolt shaft arrangement space 3 of the retaining member S, approximately half of the small diameter bolt shaft B1 in cross section is inserted and fitted into the small diameter clamping portion 7a, and the small diameter bolt shaft B1 is set so that it cannot move in the groove width direction of the small diameter clamping portion 7a.

[0047] As shown in FIG. 2, the pressing member P is connected to the female thread cap member F so as to be rotatable freely with the accommodated portion 31 of the pressing member P accommodated in the accommodation portion 22 thereof, and therefore the circumferential position of the pressing member P relative to the female thread cap member F is determined so that the small diameter pressing female thread portion 34 of the pressing member P is arranged vertically. In this state, when the small and large diameter pressing female thread portions 34, 35 of the pressing member P are pressed against the male thread standing portions 2 of the holding member S, the small and large diameter female thread forming block portions 41, 42 of the pressing member P are inserted into the first and second bolt shaft arrangement spaces 3, 4 of the holding member S, making it impossible for the pressing member P to rotate relative to the holding member S. As the female thread cap member F rotates, the trapezoidal female thread portion 21 of the female thread cap member F and the trapezoidal male thread portion 5 of each male thread standing portion 2 screw together, and the female thread cap member F screws forward relative to the holding member S. Just before the female thread cap member F reaches the screw end, the total of eight positioning protrusions 36, 37 formed on the female thread cap member F are inserted and fitted into the total of eight positioning recesses 11, 12 of the holding member S, respectively, and the position along the circumferential direction of the pressing member P relative to the holding member S is determined.When the female thread cap member F reaches the screw end in this state, a pair of anti-loosening pressed protrusions 24 formed on the open side end face 22a of the female thread cap member F and a pair of anti-loosening pressed protrusions 13 formed on the upper end face 6a of the divided base portion 6 of the holding member S are pressed against each other's opposing surfaces, increasing the rotational resistance of the female thread cap member F and making it unable to rotate. As a result, the screw-in end position of the female thread cap member F is determined, and the rotational resistance makes it impossible for the female thread cap member F to rotate in the reverse direction. The male threaded portion of a predetermined length of the vertically arranged small diameter bolt shaft B1 and the female threaded portion of the small diameter pressing female threaded portion 34 of the pressing member P are partially screwed together, so that the small diameter bolt shaft B1 is prevented from moving axially relative to the rod-shaped body clamping device A, and the small diameter bolt shaft B1 is held in a clamped state between the small diameter clamping portion 7a of the holding member S and the small diameter pressing female threaded portion 34 of the pressing member P.

[0048] Furthermore, by screwing the anti-reverse rotation screw 71 into the screw hole 15 of the base extension portion 14 of the holding member S, the fingertip hook plate portion 26 of the female thread cap member F abuts against the head of the screw, preventing the female thread cap member F from rotating reversely and loosening. Furthermore, as shown in Figure 5, by pressing the surface of the small diameter bolt shaft B1 with the anti-rotation pressing screw 72 inserted into the screw through hole 44 of the pressing member P, rotation of the bolt shaft B1 can be prevented.

[0049] Next, to fix the large diameter bolt shaft B2 (which is a quarter of the bolt) vertically to the fixed plate E, as shown in Figures 18 to 20, compared to the above case in which the small diameter bolt shaft B1 (which is a third of the bolt) is fixed, the pressing member P connected to the female thread cap member F so as to be able to rotate freely is rotated 90° in either direction relative to the large diameter pressing female thread portion 35 to position the large diameter pressing female thread portion 35 vertically, and the use-preventing rod portion 43 provided at one axial end of the large diameter pressing female thread portion 35 is broken to make it possible to position the large diameter bolt shaft B2 in the large diameter pressing female thread portion 35. Therefore, in the same manner as in the case of the small diameter bolt shaft B1, a part of the large diameter bolt shaft B2 arranged vertically is set in the large diameter clamping part 8a at the bottom of the second bolt shaft arrangement space 4 of the holding member S, and the female thread cap member F is rotated to screw the trapezoidal female thread 21 into the outer trapezoidal male thread 5 of each male thread standing part 2 of the holding member S, and a part of the large diameter bolt shaft B2 is pressed and clamped by the large diameter clamping part 8a of the holding member S and the large diameter pressing female thread 35 of the pressing member P, so that the large diameter bolt shaft B2 is fixed vertically to the fixed platen E via the rod-shaped clamping tool A. In FIG. 5(b), the eight positioning protrusions 36, 37 formed on the pressing member P and the eight positioning recesses 11, 12 formed on the holding member S are fitted to each other with their fitting positions changed.

[0050] In addition, to clamp and fix one end of a small diameter bolt shaft B1 that is arranged horizontally, as shown in Figure 21, one end of the small diameter bolt shaft B1 is set in the small diameter clamping portion 7b formed horizontally at the bottom of the second bolt shaft arrangement space 4 of the holding member S that constitutes the rod-shaped body clamping device A, whose base 1 is fixed horizontally to a fixed plate E, and the small diameter pressing female thread portion 34 of the pressing member P is arranged horizontally relative to the female thread cap member F (the state shown in Figure 20), and the female thread cap member F is screwed into each male thread standing portion 2 of the holding member S, so that one end of the small diameter bolt shaft B1 is clamped and fixed between the holding member S and the pressing member P.

[0051] Similarly, when the large diameter bolt shaft B2 is set in the large diameter clamping portion 8b of the second bolt shaft arrangement space 4 of the retaining member S, and the large diameter pressing female thread portion 35 of the pressing member P is arranged horizontally relative to the female thread cap member F (as shown in Figure 2), the female thread cap member F is screwed into each male thread standing portion 2 of the retaining member S, and one end of the horizontally arranged large diameter bolt shaft B2 is clamped and fixed between the retaining member S and the pressing member P.

[0052] Furthermore, as shown in FIG. 22, when one end of the horizontally arranged small diameter bolt shaft B1 is positioned in the recessed corner 74 of the wall body K, the base 1 of the holding member S is fixed vertically at the recessed corner 74, and one end of the small diameter bolt shaft B1 is clamped and fixed to the rod-shaped body clamping tool A, while the other end is clamped and fixed to the rod-shaped body clamping tool A with the base 1 arranged horizontally. This allows the end of the horizontally arranged small diameter bolt shaft B1 to be positioned up to the portion close to the recessed corner 74 of the wall body K.

[0053] In the above embodiment, the small diameter clamping portion 7a (7b) and the large diameter clamping portion 8a (8b) are formed continuously along the screw rotation axis C of the female thread cap member F at the bottom of the first and second bolt shaft arrangement spaces 3, 4 formed perpendicular to each other in the retaining member S, and two types of pressing female threads 34, 35 for small and large diameters are provided on the pressing member P which is connected to the female thread cap member F so as to be able to rotate freely, and one of the two types of pressing female threads 34, 35 of the pressing member P corresponding to the diameter of the bolt shaft B1 (B2) on which the retaining member S is arranged is selected, thereby making it possible to clamp two types of bolt shafts B1, B2 of small and large diameters in different directions using the same rod-shaped body clamping tool A. However, various forms such as the small diameter clamping portion and the large diameter clamping portion provided in the rod-shaped body clamping tool can be considered, as follows.

[0054] In the above embodiment, a single bolt shaft arrangement space is simply formed in the retaining member, and clamping portions for small and large diameters are provided at the bottom of the space in succession along the direction of the screw rotation axis of the female thread cap member. The arrangement direction of the bolt shaft can be changed by rotating the rod-shaped clamping device itself to change the fixed arrangement position relative to the fixing member, thereby clamping two types of bolt shafts, small and large diameter B1, B2, in different directions.

[0055] In addition, first and second types of bolt shaft arrangement spaces perpendicular to each other are formed in the retaining member, and only a small diameter clamping portion and a large diameter clamping portion are formed at the bottom of these spaces.The arrangement direction of the bolt shafts can be changed by rotating the rod-shaped body clamping device itself to change the fixed arrangement position relative to the fixed member, thereby clamping two types of bolt shafts, small and large diameter B1, B2, in different directions.

[0056] Furthermore, the above object can be achieved by forming a clamping portion for the bolt shaft at the bottom of two types of bolt shaft arrangement spaces that are formed intersecting each other in the retaining member, with the main purpose being to change the arrangement direction of the bolt shaft.

[0057] In the above embodiment, a small diameter clamping portion 7a (7b) having a semicircular cross section and a large diameter clamping portion 8a (8b) having an interrupted arc cross section are formed continuously along the direction of the screw rotation axis C at the bottom of each of the first and second bolt shaft arrangement spaces 3, 4 which are perpendicular to each other, and the small diameter clamping portion 7a (7b) or the large diameter clamping portion 8a (8b) are partially fitted into the small diameter clamping portion 7a (7b) or the large diameter clamping portion 8a (8b), thereby restricting the radial movement of the bolt shafts B1, B2. However, the radial movement of the bolt shafts B1, B2 can also be restricted by the following configuration.

[0058] 23 shows another example of restricting the movement of the bolt shafts B1, B2 in the radial direction. The clamping block body 51 has a bolt shaft arrangement space 52 capable of clamping and fixing both the small-diameter and large-diameter bolt shafts B1, B2, and a small-diameter clamping portion 54a having an arc-shaped cross section is formed at the bottom of the bolt shaft arrangement space 52, into which a part of the small-diameter bolt shaft B1 is fitted. Similarly to the pressing member P, the pressing member P' has small-diameter and large-diameter block portions 55, 56 formed perpendicularly, and each block portion 55, 56 has a small-diameter pressing female screw portion 55a and a large-diameter pressing female screw portion 56a, respectively. In order to allow the block portions 55, 56 to be inserted into the bolt shaft arrangement space 52 without any gaps, the inner width of the bolt shaft arrangement space 52 and the outer width of each block portion 55, 56 are both "W", which is slightly larger than the outer diameter of the large-diameter bolt shaft B2.

[0059] Therefore, when the small diameter bolt shaft B1 is held, as shown in Fig. 23(a), when the small diameter block portion 55 of the pressing member P' is moved closer to the clamping block body 51 in a state in which the small diameter bolt shaft B1 is partially fitted into the small diameter clamping portion 54a at the bottom of the bolt shaft arrangement space 52, the small diameter block portion 55 is fitted into the bolt shaft arrangement space 52 of the clamping block body 51, and the small diameter bolt shaft B1 is clamped between the small diameter clamping portion 54a of the clamping block body 51 and the small diameter pressing female thread portion 55a of the small diameter block portion 55, thereby restricting radial movement. On the other hand, when the pressing member P' is rotated 90° relative to the clamping block body 51 to hold the large diameter bolt shaft B2, the large diameter bolt shaft B2 is inserted and arranged in the bolt shaft arrangement space 52 of the clamping block body 51, as shown in Fig. 23(b), thereby restricting radial movement of the large diameter bolt shaft B2. In this state, when the large diameter block portion 56 of the pressing member P' is moved closer to the clamping block body 51, the large diameter block portion 56 is fitted into the bolt shank arrangement space 52 of the clamping block body 51, and is clamped between the large diameter clamping portion 54b at the bottom of the bolt shank arrangement space 52 and the large diameter pressing female thread portion 56a of the large diameter block portion 56 with its radial movement restricted. When the large diameter bolt shaft B2 is placed in the bolt shank arrangement space 52, a part of its bottom enters the small diameter clamping portion 54a in a non-fitted state.

[0060] Figure 24 shows another example of restricting radial movement of the bolt shafts B1, B2, and the same parts as those in the example shown in Figure 23 are designated by the same reference numerals with an "'" added. The only difference from the example shown in Figure 23 is that the bottom of the bolt shaft arrangement space 52 does not have a concave clamping portion but is a flat clamping surface 58, but the small and large diameter bolt shafts B1, B2 are clamped and fixed in a state where their radial movement is restricted.

[0061] FIG. 25 shows a principle diagram of an example in which round bars D1, D2 with different diameters and smooth outer circumferential surfaces are clamped and fixed while restricting their radial movement. The inner width of the round bar arrangement space 61 of the holding member S" and the outer width of the pressing member P" are both "W", which is slightly larger than the outer diameter of the large diameter round bar D2. An arc-shaped clamping portion 61a is formed on the bottom surface of the round bar arrangement space 61 into which a portion of the small diameter round bar D1 is fitted, and a fitting pressing recess 62a with an arc-shaped cross section into which a portion of the large diameter round bar D2 can be fitted is formed on the surface of the pressing member P" facing the holding member S". Therefore, when the small diameter round bar D1 is set at the bottom of the round bar arrangement space 61, a part of the round bar D1 is partially fitted into the clamping portion 61a. In this state, when the tip of the pressing member P″ is inserted and fitted into the round bar arrangement space 61 of the holding member S″ and the small diameter round bar D1 is pressed by the fitting pressing recess 62a formed on the tip surface of the pressing member P″, the tip of the pressing member P″ is fitted into the round bar arrangement space 61 without any gaps, and the round bar D1 is held by the pressing member P″ in a state where radial movement is restricted. The large diameter round bar D2 is clamped and fixed between the clamping portion 61a of the holding member S". On the other hand, when a large diameter round bar D2 is set at the bottom of the round bar arrangement space 61, the radial movement of the round bar D2 is restricted, and in this state, when a pressing member P" is inserted and fitted into the round bar arrangement space 61 of the holding member S", a part of the round bar D2 fits snugly into the fitting pressing recess 62a at the tip of the pressing member P", and the large diameter round bar D2 is clamped and fixed between the fitting pressing recess 62a of the pressing member P" and the clamping portion 61a of the holding member S".

[0062] FIG. 26 shows a principle diagram of another example in which round bars D1, D2 with different diameters and smooth outer circumferential surfaces are clamped and fixed while restricting radial movement, and parts equivalent to those in the principle diagram shown in FIG. 25 are indicated with the same reference numerals followed by "'" and are only illustrated, and only the different parts will be described. The parts different from the principle diagram shown in FIG. 25 are that the bottom of the holding member S" maintains a flat shape and forms a flat clamping portion 61b, and that the tip of the pressing member P" is formed with a fitting pressing recess 62b with a semicircular cross section corresponding to the outer diameter of the small diameter round bar D1. The principle in which the small and large diameter round bars D1, D2 can be clamped and fixed while restricting radial movement is the same as the example shown in FIG. 25.

[0063] In the above embodiment, a bolt shaft is used as an example of a rod-shaped body, but the rod-shaped body clamping device according to the present invention can clamp general rod-shaped bodies other than bolt shafts and round bars with smooth outer circumferential surfaces. The cross section of the rod-shaped body is not limited to a circular shape, and it can clamp and fix even rectangular shapes, 3mm or 4mm rebars.

[0064] In addition, while the above embodiment is an example of clamping and fixing rod-shaped bodies of different diameters, it is also possible to configure the device to accommodate only changes in the placement posture or orientation of the rod-shaped bodies, without accommodating different diameters.
