Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for fixing conduits, and more particularly to a device for simultaneously fixing a plurality of conduits for passing electric wires or fluids to a grooved rail member.

[0002]

[Prior art and its technical problem]

 Buildings, structures, structures such as ordinary houses, shops, sales offices, warehouses, factories, railway stations, airport buildings, gymnasiums, various concrete or wooden buildings such as theaters, tunnels, underpasses, and viaducts. In various facilities such as railways, elevated roads, and bridges, various electric wires (wires or cables) for power supply, credit, and telephone are laid. As is well known, electric wires are covered with an insulating coating or a protective coating, but if they are stretched around the ceiling area, sidewalls, and floors of the above-mentioned buildings and facilities as they are, they may come into contact with equipment, earthquakes, etc. Alternatively, it may be damaged by being bitten by animals such as rats, it may be chemically adversely affected by contact with rainwater, raw concrete, mortar, etc., or it may be affected by electromagnetic waves. As a countermeasure, a conduit made of metal or the like is connected to form a conduit, and an electric wire is passed through this. Normally, pipes are circular pipes, and more than one pipe is often arranged in parallel.Therefore, in order to simplify the construction, generally, a grooved rail member is fixed on the ceiling, side wall, or floor of the pipe formation area. A method is adopted in which saddles are made by fixing them at intervals, and the conduits are passed orthogonally on the saddles, and fixed to the groove-shaped rail member with a fixing tool.

As shown in FIG. 15, the groove-shaped rail member 4 has a web (bottom wall) 4a and flanges (sidewalls) 4b and 4b rising from both ends thereof, and the flanges 4b and 4b from the upper end. Top walls 4c, 4c extending toward the center in the width direction are integrally formed, and the front ends of the top walls 4c, 4c are bent at right angles to form hanging walls 4d, 4d. The pair of hanging walls 4d, 4d Thus, the inlet groove 42 having a width W ₁ narrower than the inner width W of the flange is formed. As a fixture for fixing the conduit A to the groove-shaped rail member 4, conventionally, as shown in FIGS. 15 and 16, the lower end has hook portions 50, 50 for the hanging walls 4d, 4d, and the upper portion has A metal fitting B ₁ having a through hole 51 larger than the bolt shaft diameter, a metal fitting B ₂ having the same size and shape as the metal fitting B ₁ except that a screw hole 52 is formed in the upper portion, and a set of these metal fittings. A structure in which a bolt C that connects B ₁ and B ₂ at the upper portion is combined is used. However, in this structure, when fixing the conduit A, the metal fittings B ₁ and B ₂ are disassembled and put into the groove-shaped rail members 4 separately, and then the conduit A is sandwiched face to face and the bolts are clamped. It becomes the work of connecting by C. In addition, since the metal fittings have the same shape and the through hole 51 is formed in one of them and the female screw hole 52 is formed in the other, it is easy to mistakenly disassemble the two disassembled metal fittings B ₁ and B ₂ in the grooved rail member. , Frequent failures such as the bolt C is not tightened from the side of the metal fitting with the screw hole. Therefore, there is a problem that workability and work efficiency are extremely poor. In addition, since the part that sandwiches the conduit A from the left and right and that protrudes above the groove-shaped rail member is tightened, the lower parts of the metal fittings B ₁ and B ₂ will be opened by strong tightening, and a large operating force will be required for fixing. The power tends to be insufficient. Moreover, since the bolt projects in the longitudinal direction of the grooved rail member, it becomes difficult to rotate the bolt with a tool such as a screwdriver, and the order of fixing the conduits in the longitudinal direction of the grooved rail member is limited. For this reason, in particular, when a plurality of conduits are arranged and fixed in parallel to a groove-shaped rail member, conventionally, it is necessary to arrange independent metal fittings for each conduit and operate them separately. The problem is that the workability and work efficiency are poor, and it is difficult to bring the placement intervals L of the conduits close to each other or to fix them accurately at a fixed interval, and the resulting conduits are likely to be distorted. Could not be resolved. In addition, since the upper part of the metal fitting largely protrudes in the radial direction of the conduit, there is a problem in that the appearance is bad and the bolt may be injured by contact with fingers, etc., or the bolt may be easily rotated to the loose side.

The present invention was devised to solve the above-mentioned problems, and an object thereof is to provide a plurality of conduits in close contact with a grooved rail member for a saddle. Can be fixed accurately and surely at the intervals of the above, and this work can be performed easily and quickly.Also, protrusions such as screw shafts hardly appear outside the grooved rail member, and therefore the appearance is good. Another object of the present invention is to provide a device of this kind that does not damage the fingers and the like, or loosens the fixed state of the conduit due to careless rotation of the screw.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a device for fixing a conduit to a grooved rail for a saddle in which a wall having a web and flanges rising from both ends of the web is connected to a flange to form an inlet groove. One or more hugging curved portions are formed through the connecting portion on the hugging curved portion that is continuously provided to the slanted leg portion that has the locking portion for the end surface of the wall that forms the inlet groove, A fixture main body having a seat plate portion at the lower end of the final holding curved portion, a screw member having a shaft portion inserted through a through hole formed in the seat plate portion, and a screw member screwed to the shaft portion of the screw member to approximately 90 It has a structure in which it is provided with a blade plate for tightening that is rotatable up to a degree. In the present invention, the "conduit" includes various metal tubes such as iron-based and lead-based tubes, and various materials such as synthetic resin tubes typified by vinyl chloride. The present invention is also applicable to the case where a conduit for inserting various wires such as a liquid typified by water and a gas typified by fuel gas is fixed to the grooved rail member, in addition to a conduit for inserting a wire or the like. Applied to.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows an application example of the present invention, in which A is a conduit, which is sequentially connected by a threadless coupling D. E is the device of the present invention. The groove-shaped rail members 4 and 4 are fixed in parallel in advance at intervals shorter than the length of the conduit A (for example, 3 to 5 m) according to the pipeline design. This fixing method is arbitrary, and in the figure, in the ceiling area, a plurality of sets of hanging rods 53 and 53 are hung from the upper wall 54, and a groove shape is formed by the hanging rods 53 and 53 and nuts. The rail member 4 is connected and supported near both ends in the longitudinal direction. Further, on the side wall 55, the floor 56 and the like, the grooved rail members 4 and 4 are fixed by anchor bolts and nails 57 that penetrate the web. It goes without saying that this method may be adopted as a method for fixing the grooved rail member in the ceiling area. 2 to 5 show the device E of the present invention. The device E of the present invention is roughly divided into a fixture body 1 having a special structure as described below, a screw member 2 inserted through the fixture body 1, and a blade plate 3 disposed below the fixture body 1. First, the fixture main body 1 is formed by punching and pressing a metal strip such as an iron-based, aluminum-based, or copper-based strip, or by molding a synthetic resin material by compression molding or injection molding.

The fixture body 1 has a leg portion 11 that is narrower than the inlet groove 42 of the groove-shaped rail member 4 and extends long at an inclination angle of 20 to 40 ° with respect to a vertical plane. In the lower part of 11, there are formed left and right locking portions 13 1, 13 having a width capable of contacting the hanging wall end faces 40, 40 of the grooved rail member 4. The leg portion 11 is provided with a first hugging curved portion 10 having a curvature capable of contacting at least one-third or more of the circumference of the conduit A to be continuously fixed and a width wider than the inlet groove width. A connecting portion 6 having a required length is formed continuously on the holding curved portion 10 toward the front. At the other end of the connecting portion 6, a second holding curved portion 100 having a width wider than the entrance groove width is formed, like the first holding bending portion 10, and further the second holding portion is formed. A connecting portion 60 having a required length is continuously provided at the lower end of the bending portion 100 for the front. At the front end of the connecting portion 60, the third (final in this embodiment) hugging bending portion 101 similar to the above is formed. A seat plate portion 12 having a short projecting length is bent and formed in a substantially horizontal shape at the lower end of the final holding curved portion 101, and the seat plate portion 12 has a shaft portion diameter of a screw member described later. A larger through hole 15 is formed. In the illustrated example, an annular ridge 16 is formed around the through hole 15. Then, in order to prevent the seat plate portion 12 from falling below the inlet groove when it is mounted on the grooved rail member 4, the final holding curved portion 101 is required from the base end of the seat plate portion 12. Tapered edges 17, 17 having an inclination angle are formed.

FIGS. 6A to 6D show another embodiment of the fixture main body 1 according to the present invention. (a) shows a second (final) holding curve 100 formed on the first holding curve 10 following the leg 11 via the connecting portion 6, and this second holding curve 10 is formed. A seat plate portion 12 is provided so as to project from the descending end of the curved portion 100. (b) shows that the fourth (final) holding curve portion 102 is continuously provided from the lower end of the third holding curve portion 101 in the embodiment of FIGS. 3 to 5 through the connecting portion 61. The seat plate 12 is provided at the lower end of the seat plate 12. In (c), another connecting portion 62 and a hugging bending portion 103 are added in (b) to form five hugging bending portions. The present invention naturally includes a case where there are six or more holding curved portions. Further, in the above description, the connecting portions 6, 60, 61, 62 ... Are not necessarily required to have a linear shape, and may have a curved shape as representatively shown in (a). Further, each connecting portion may be configured so as to warp as it approaches the final holding curved portion. Further, the arc lengths of the holding curved portions 10, 100, 101 ... (The contact length with the circumferential surface of the conduit) do not necessarily have to be equal. That is, for example, the arc lengths of the first and last hug curves are increased, and the middle hug curves (100 in FIG. 3, 100, 101 in FIG. 6 (b), 100, 101, 102 in FIG. 6 (c)). ) The length of the arc may be reduced. This is easily accomplished by changing the curvature of the hug curve (the greater the curvature, the smaller the arc length). Further, when the width of the connecting portion is wider than the inlet groove width W _{1 of the} grooved rail member 4, the connecting portions 6, 60, 61, 62 are formed on the upper surface 43 of the grooved rail member 4 by the completion of the tightening by the blade plate 3. The height from the top surface of the holding curved portion should be set so that it does not touch. When the width of the connecting portion is narrower than the inlet groove width W ₁ of the groove-shaped rail member 4, the height may be increased so as to reach a size below the inlet groove 42 of the groove-shaped rail member 4. FIG. 6 (e) shows this example, and in this case, it is desirable to use an intermediate tightening mechanism described later together.

Next, in the screw member 2, the shaft portion 20 in which male screws are arranged in a row is inserted into the through hole 15 of the seat plate portion 12, and the head portion 21 is in contact with the seat plate portion 12. The screw member 2 may be a normal bolt type with a driver groove or a screw, or may be one having a function of preventing overtightening. That is, as an example thereof, as shown in FIGS. 3 to 5, a cross-sectional area is formed on the top surface of the angular head 21 on the shaft portion 20 so that the head portion 21 is broken when a predetermined torque is reached. An example is one in which a regulated cross-section reduction portion 22 is formed, and a second long head 23 having a vertically long flat shape is formed on the cross-section reduction portion 22. Next, the tightening vane plate 3 is arranged below the seat plate portion 2 and has a female screw hole 30 in the center thereof, and the shaft portion 20 is screwed into the female screw hole 30. The blade plate 3 has a shape other than a perfect circle, that is, a plane shape having a difference in length between a pair of opposing sides 31, 31 and the other sides 33, 33. FIGS. 7 (a) to 7 (c) show an embodiment of the vane plate 3. In FIG. 7 (a), the guide surfaces 32, 32 are provided at the diagonal corners of the pair of sides 31, 31 forming the maximum dimension l. Is absent. In this embodiment, by setting the pair of sides 31, 31 to be longer than the flange inner width W, the flange groove width in a considerable range can be dealt with. In (b), a pair of sides 31, 31 forming the maximum dimension is formed in the central portion, and guide standard surfaces 32, 32 are provided on both sides of the side 31. Since this embodiment has no turning direction, it is easy to handle. (c) It is a so-called propeller shape in which waves 35, 35 are formed symmetrically with respect to the internal threaded hole 30 and gradually increasing in the direction of rotation. In this embodiment, the blade plate 3 can be lifted with a small amount of rotation of the screw member 2, and a stronger tightening due to the spring effect can be obtained. The shape of the vane plate 3 is not limited to the above-mentioned embodiment. In short, when tightening, the blade plate 3 moves up and down along the lead of the shaft portion 20, and the upper surface abuts the end surfaces 40, 40 of the hanging wall of the channel member 4. Anything you can get. That is, for example, the guide surfaces 32, 32 and the sides 33 1, 33 are not necessarily linear and may be arc surfaces. Further, streaks or other friction coefficient increasing portions may be formed on the pieces (end surfaces) 31 on the maximum dimension side, or as shown by the phantom line in FIG. Knurls, corrugations, or other friction coefficient increasing portions 36 may be formed at least in the regions of the hanging wall that contact the end faces 40, 40.

The blade plate 3 may be simply screwed into the shaft portion 20, but a falling-out prevention mechanism may be provided so as not to fall off from the shaft portion 20 due to vibration or the like during transportation or a conduit fixing operation. 8 (a) to 8 (e) show the columns. In (a), an adhesive substance or an adhesive tape 24 is attached to the thread of the shaft portion 20. In (b), a cap 25 made of a soft material such as synthetic resin or rubber is fitted to the shaft portion. (c) is a ring (flange) 26 having an elastic tongue piece 260 fitted to the shaft portion. In (d), a hole 201 with or without a screw is formed in the shaft portion 20, and a fastener 27 having a protruding portion 270 is fitted therein. According to these embodiments, the blade plate 3 does not normally fall off, but can be removed from the shaft portion 20 if necessary. Therefore, a blade plate having a different size 1 can be exchanged, and one fixing tool body 1 can be applied to the groove-shaped rail member 4 having various inner flange widths W. In FIG. 8 (e), instead of the above, the shaft portion 20 itself is locally plastically deformed to form the protrusions 28, 28. In this case, the vane plate 3 cannot be replaced, but it can be securely removed. It can be stopped. In either case, the fall prevention mechanism is installed after the blade plate 3 is screwed through.

The above is the basic configuration of the present invention, but various other modes can be adopted. 9 to 14 show an example thereof. 9 to 11 show a mode in which the tightening mechanism 7 is arranged also in the connecting portions 6, 60, 61, .... The intermediate tightening mechanism 7 includes a boss hole 70 formed in the connecting portions 6, 60, 61, ..., a screw (or bolt) 200 having a shaft 205 that is inserted into the boss hole 70, and a rotation of the screw 200. And a vane plate 300 that rises along the axis 205 and is in pressure contact with the hanging wall end surfaces 40, 40 of the groove-shaped rail member 4. In FIG. 9, a male screw 202 having a diameter larger than that of the boss hole 70 is provided under the head portion, and a blade plate 300 is screwed into the male screw 202, and the boss hole 70 is provided at the lower end of the male screw 202 via a taper portion or a step portion 203. A thinner shaft 205 is formed. In the embodiment of FIG. 10, instead of the screw of FIG. 9, a deformed portion 204 having a non-circular cross section such as a polygonal shape or an oval shape is provided, and a blade plate 300 having a hole of the same shape is inserted into this deformed portion 204. The blade plate 300 is integrally rotated by the rotation of the screw 200, and the shaft 205 is formed below the deformed portion 204 via the tapered portion or the stepped portion 203. FIGS. 9 and 10 are effective when the connecting portion is formed at a deep position as shown in FIG. 6 (e). As a component independent of the fixture main body 1, the connection at a desired position requiring fixing is made. Partly used for selection. In some cases, the lower end protruding from the boss hole of the shaft 205 may be enlarged by caulking, but from the viewpoint of usability and man-hours, it is advantageous to use the attachment type as shown in the figure. FIG. 11 shows a configuration in which a shaft member 205 is inserted into the boss hole 70 by using a combination of a screw member attached to the seat plate portion 12 and a blade plate, and the blade plate 300 is screwed into the shaft portion below the connecting portion. .. This embodiment is used when the connection is shallow. The vane plate 300 shown in FIGS. 9 to 11 may be the one shown in FIGS. 7-A to 7-C. Further, the screw 200 may use the torque control screw shown in FIG.

FIG. 12 shows an embodiment in which a length adjusting mechanism 8 for varying the distance L between the holding curved portions is provided on at least one of the connecting portions 6, 60, 61 .... The length adjusting mechanism 8 is composed of connecting protrusions 6a and 6b, which are divided into two in the middle, bolts or screws 80, and nuts 81, and one of the connecting protrusions 6a has a bolt or screws 80. A through hole 600 for inserting the through hole is formed, and a long hole 601 is formed in the other connecting projection 6b. According to this mechanism, the nut 81 is loosened, one of the connecting projections 6a or 6b is slid, and then the nut 81 is tightened to form a connecting portion having a desired length. FIG. 13 shows that the fixing device main body 1 can be separated and integrated into a plurality by applying the connecting portion dividing method of FIG. In the illustrated example, it is divided into a front end body 1a, a rear end body 1b, and an intermediate body 1c, and the connecting protrusions 6a of the front end body 1a and the connecting protrusions 6a of the rear end body 1b have through holes 600,600. Is provided, and long holes (or through holes) 601 are provided in the connecting projections 6b, 6b at both ends of the intermediate body 1c, and the bolts or screws 80 and the nuts 81 are used for connection. If this mechanism is used, the number of fixed conduits can be arbitrarily changed by preparing an intermediate body 1c having various numbers of bending portions for holding. In FIG. 14, a hinge mechanism 9 is provided on the leg portion 11 of the fixture main body 1 to facilitate the fitting into the conduit A. This hinge mechanism 9 can be formed even if a butterfly plate, which is a separate component, is joined by welding or the like. However, in the case of metal, when the leg is punched out, a forked portion and corresponding projections are made, and they are curled to form a shaft hole, and then a pin is fitted. 9 to 14 may be applied individually or in combination of two or more kinds. In the other drawings, 5 is a reinforcing rib bulgingly formed on the fixture main body 1, and 14 is a conduit rib axis of the holding curved portions 10, 100, 10 ... for facilitating the setting of the interval between the guide tubes A. Is a center indicating portion provided on the outer surface of the matching portion of.

[0013]

[Operation of the embodiment]

 The method of use and operation of the present invention will be described. During construction, as shown in FIG. 1, the grooved rail members 4 and 4 are fixed in parallel at intervals shorter than the length of the conduit A (for example, 3 to 5 m). I'll do it. Then, the device E of the present invention is set on the grooved rail members 4 and 4. In this operation, the leg 11 is inserted so that the width direction of the leg 11 is parallel to the inlet groove 42 of the groove-shaped rail member 4, and the fixture is fixed so that the width direction of the leg after insertion is orthogonal to the groove-shaped rail member 4. All you have to do is rotate the whole body, so the set can be done with one touch. In order to fix the conduits A, A, A after they are hung on the groove-shaped rail members 4, first, while holding the leg portions 11 in the groove-shaped rail members 4 and 4, tilt the whole fixture main body 1 and hold it. The bending portions 10, 100, 101 ... Are opened laterally so that the conduits A, A, A are respectively located below the holding bending portions 10, 100, 101. The fixture main body 1 may be turned down so as to be parallel to the inlet groove 42. In this way, the conduits A, A, A are surrounded by the respective hugging curved portions 10, 100, 101 ... With the lower surface in contact with the upper surfaces 43, 43 of the groove-shaped rail member 4, and the engagement of the leg portion 11 is prevented. The stoppers 13, 13 are locked to the end faces 40, 40 of the hanging wall of the grooved rail member 4. On the other hand, the taper wires 17, 17 are appropriately separated from the groove entrance edges 41, 41 due to the displacement of the leg portion 11. Next, when the screw member 2 is rotated, since the pieces 31 and 31 on the maximum dimension side are parallel to the groove longitudinal direction at the beginning of rotation of the screw member 2, the blade plate 3 rotates together. Since the distance between the sides 31 and 31 is equal to or greater than the flange inner width W, the sides 31 and 31 come into contact with the flange inner surfaces 44 and 44 within 90 ° of rotation, and no further rotation occurs. Therefore, as the screw member 2 continues to rotate, the blade plate 3 does not rotate but rises along the shaft portion 20, and the upper surface 34 strongly contacts the hanging wall end surfaces 40, 40. As a result, the leg portion 11 is pulled upward, and the final holding curved portion (101 in FIG. 3) is pulled downward. As a result, a pulling action toward the middle occurs, and the conduit A is held near the connecting portion. By pressing the wall of the holding curved portion, the intermediate holding curved portion (100 in FIG. 3) is elastically deformed to the diameter reducing side through the connecting portion (60 in FIG. 3). As a result, the wrapping force of the intermediate holding bending portion is strengthened, and the conduits A, A, A are fixed as shown in FIGS. 3 to 5. If the conduit is made of synthetic resin, the hugging curved portion is closer to the outer circumference because it has elasticity. In any case, the present invention allows a plurality of conduits to be fixed at one time with a fixed and minimum necessary interval in one fixing operation. This is the state shown in FIG.

When the tightening mechanism 7 as shown in FIGS. 9 to 11 is used, the screw 200 is inserted using the boss hole 70 provided in the desired connecting portion 6, 60, 61 ... By rolling, the blade plate 300 ascends along the axis as in the case of the seat plate portion 12, and comes into pressure contact with the hanging wall end faces 40, 40. Therefore, even if the number of the holding curved portions is large, or even if there are a plurality of conduits having a slightly smaller diameter, they can be firmly fixed. 9 and 10 can be used regardless of whether the fixing work is completed or not completed. When the length adjusting mechanism 8 shown in FIG. 12 is used, the length of the connecting portion, and hence the interval of the hugging bending portion, can be changed at any time to meet the construction specifications or the changes. By providing the center display portion 14 of the holding curved portion, it is possible to easily determine the interval between the conduits without having to detect the conduit axis of each conduit. In the present invention, since the blade plate 30 is arranged below the seat plate portion, and the seat plate portion 12 supports the head of the screw member 2, the screw member 2 can easily and reliably apply the rotational torque. Can be given to. Further, the required projecting length of the seat plate portion 12 is short, so that the entire apparatus can be made smaller and more compact, and the interval between the conduits A, A can be reduced.

In the case where the screw member 2 has the second head portion 23 having a long flat shape on the head portion 21 via the cross-section reducing portion 22, the cross-section is obtained when the specified torque is reached. Since the reduced portion 22 breaks, there is no concern that the conduit A is subjected to excessive tightening force and is deformed or damaged. Moreover, since the loss of the second head 23 can be visually observed from the side surface of the groove-shaped rail member 4 or the like, it is possible to instantly determine whether or not the conduit fixing work is completed.

[Effect of the device]

 According to the present invention described above, the saddle type groove rail 4 for the saddle is provided with the web 4a and the flanges 4b, 4b rising from both ends of the web 4a and the flanges 4a, 4a having the walls forming the inlet groove 42 connected in series. In the device for fixing the conduit A, the fixture body 1 is connected to the holding curved portion 10 following the oblique leg portion 11 having the engaging portion 13 for the end face of the wall forming the inlet groove 42, and the connecting portion. One or more hugging curved portions 100 are formed through the through holes, and the seat plate portion 12 is provided at the lower end of the final hugging curved portion, and the through hole 15 formed in the seat plate portion 12 is provided with a shaft. Since the shaft portion of the screw member 2 having the portion inserted therein is provided with a blade plate 3 for tightening which is screwed into the screw member 2 and is rotatable up to about 90 degrees, each of the conduits A and A is held. If the main body 1 is laid down under the bending portions 10, 100 ... For the conduits A, A Surrounded by the holding curved portions 10, 100 at short intervals, the blade plate 3 also enters the inlet groove 42 of the groove-shaped rail member 4, and when the screw member 2 is rotated, the blade plate 3 automatically becomes the inlet groove. When the screw member 2 is orthogonal to each other and is subsequently rotated, the blade plate 3 is vertically moved and is brought into close contact with the bottom of the wall forming the inlet wall. As a result, the final holding curving portion 101 is pulled downward, and the intermediate holding curving portion is elastically deformed, and the winding force around the conduit is strengthened. Therefore, a plurality of conduits A, A can be firmly fixed at a minimum required interval by almost one-touch simple operation, and workability and work efficiency can be significantly improved. Even though it can be fixed, the number of parts is small, the structure is simple, and the excellent effect that work can be performed safely on the ceiling etc. without any trouble is obtained.
