Description

The present invention relates to a fixing bracket for a hanging bolt and a structure using the bracket.

In reinforced concrete structures such as buildings, decorative panels that make up the ceiling surface of the room are attached at intervals from the ceiling surface. In the attic space between the ceiling surface and the decorative panel, cables for electricity and communication, ducts for air conditioning, air conditioning equipment, lighting equipment, etc. are arranged. For these cables, ducts, equipment, etc., a large number of hanging bolts suspended from the concrete ceiling surface are provided, and the hanging bolts are stretched between the hanging bolts. In the case of a new structure, the decorative panel for the ceiling may not be attached, but it will be aerial work on the stepladder scaffolding. In the case of an existing structure, since a decorative panel for the ceiling is attached, the work is performed in a narrow space behind the ceiling between the concrete ceiling surface and the decorative panel. Therefore, a metal fitting that can be attached to a hanging bolt with one touch has been desired.

Utility Model Registration No. 3135385 Gazette

Therefore, as a result of repeated diligent research, the prototype metal fitting 200 shown in FIG. 11 was produced based on an idea. The metal fitting 200 is composed of a support member 20, a pair of screwing members 122a and 122b fixed to the support member 20, and a hanging jig 26. On the inner surface of the screwing members 122a and 122b, a female screw 28 to be screwed with the male screw 18 formed on the shaft portion 16 of the hanging bolt 14 is formed. Further, a hanging jig 26 is provided on the side surface of the support member 20. The metal fitting 200 is slanted with respect to the suspension bolt 14, and after passing the shaft portion 16 of the suspension bolt 14 through the gap between the screwing member 122a and the screwing member 122b, the metal fitting 200 is passed through the shaft portion 16 of the suspension bolt 14. The female screw 28 of the screwing members 122a and 122b and the male screw 18 of the hanging bolt 14 are screwed together so as to be screwed together. By suspending a duct or the like on the suspension jig 26 using a wire or the like, a reversing force is applied to the metal fitting 200 against the suspension bolt 14 (directions in which the screwing members 122a and 122b each press the shaft portion 16 of the suspension bolt 14). The force of) is applied, and the screw becomes tight.

However, when a duct or the like is suspended from the metal fitting 200 and a force is applied to the hanging jig 26 from the bottom to the top, the metal fitting 200 becomes slanted with respect to the suspension bolt 14 and the screwing member. I noticed that there is a problem that the female screw 28 of 122a and 122b and the male screw 18 of the hanging bolt 14 are disengaged and the metal fitting 200 falls off from the hanging bolt 14. It is very dangerous for the metal fitting 200 to suddenly come off when the metal fitting 200 is used to prevent the operator from falling. Further, when the metal fitting 200 is used for installing ducts, pipes, and wiring, if it is unexpectedly removed, there is a problem that the work must be redone. Therefore, after attaching the metal fitting 200 to the hanging bolt 14, the present invention has been further studied in order to prevent the metal fitting 200 from being removed unless the operator intentionally removes the metal fitting 200.

In addition, when the inventor of the present application conducted a prior application search before filing an application, Patent Document 1 was found. It can be said that the embodiment shown in FIGS. 1 and 2 of Patent Document 1 has substantially the same basic configuration as the metal fitting 200, but the problem of the present inventor has not been solved at all.

An object of the present invention is to provide a fixing bracket for a hanging bolt that can be attached to the hanging bolt with one touch and cannot be easily removed from the hanging bolt.

In order to solve the above-mentioned problems, the hanging bolt fixing bracket according to the present invention can be fixed to any part of the hanging bolt having a male screw formed on the shaft portion suspended from the structure. The metal fitting is provided with a support member having a longitudinal direction along the suspension bolt and an inner surface at a position separated from the support member in the longitudinal direction along the male screw formed on the shaft portion of the suspension bolt. A contact member that is arranged in a direction in which the inner surfaces face each other and is arranged at a position that is spaced apart from the diameter of the hanging bolt, and has a female screw that can be screwed with the male screw on either or both of the inner surfaces. The support member is provided with a lock mechanism for locking the suspension bolts arranged between the facing inner surfaces of the contact members so as not to be slanted.

In such a fixing bracket for a hanging bolt, the locking mechanism allows the shaft portion of the hanging bolt to enter and locks the fitting, and the shaft portion of the hanging bolt can be discharged by releasing the lock by an external force.

Further, in the fixing bracket for the suspension bolt, the lock mechanism is formed vertically to the J-shaped member and a J-shaped member having a parallel portion for guiding the suspension bolt and a bottom portion on which the suspension bolt is placed. Engagement between a rotating shaft portion, an inclined end surface that can rotate around the rotating shaft portion and guides the hanging bolt to the parallel portion, and a hanging bolt located at the bottom of the J-shaped member. A rotating member having an end portion and an urging means for urging the rotating member around the rotating shaft portion are provided.

Further, in the fixing bracket for the suspension bolt, the lock mechanism is formed of a member having a spring property in whole or in part, and includes an inclined portion and a storage portion which are expanded and stored by the shaft portion of the suspension bolt. is there.

Further, in the hanging bolt fixing bracket, the locking mechanism is at a position facing the inner surface of at least one of the contact members, and is a protrusion that can protrude from the back surface of the support member and returns to the back surface side by an external force. To prepare the body.

It is a structure using the fixing bracket for hanging bolts described in any of the above.

According to the fixing bracket for hanging bolts according to the present invention, the contact member having the female screw formed on at least one inner surface is arranged on the support member by shifting the position in the axial direction (longitudinal direction) so as to face the inner surface. ing. Since the two contact members are arranged so as to have at least a width (distance) through which the shaft portion of the suspension bolt can pass, they are beveled between the two contact members at an angle with respect to the shaft portion of the suspension bolt. After passing the shaft, raise the hanging bolt fixing bracket vertically so as to be parallel to the hanging bolt. By this operation, the male screw of the hanging bolt and the female screw of the contact member are screwed together, but the shaft of the hanging bolt is further locked by the lock mechanism, and the fixing bracket for the hanging bolt becomes slanted with respect to the hanging bolt. There is no such thing. Therefore, since the fixing bracket for the hanging bolt does not come off carelessly from the hanging bolt, work for ducts, piping, wiring, etc. in narrow places such as the ceiling can be performed with confidence, and workability is dramatically improved. Improve. Moreover, since the fixing bracket for the hanging bolt can be fixed to the hanging bolt with one touch, the workability is further improved.

(Hanging bolt)
As shown in FIGS. 1 and 2, the hanging bolt fixing metal fitting (hereinafter referred to as “the main metal fitting”) 10 according to the present invention is attached to an arbitrary position of the hanging bolt 14 suspended from the structure 12. The structure 12 is often a reinforced concrete structure such as a building or a tunnel, but the structure 12 is not limited thereto. The hanging bolt 14 has a male screw 18 formed on the entire surface of the shaft portion 16. The effective diameter of the suspension bolt 14 is set according to the weight of the object to be suspended. When the suspension bolt 14 is used in a high humidity environment, stainless steel or steel with plating or rust prevention treatment is selected, and a steel material is usually used. One end of the hanging bolt 14 is bent into a U-shape or an L-shape to be embedded and fixed in concrete, and the other end is hung downward.

(Fixing bracket for hanging bolts)
The metal fitting 10 includes a support member 20, a pair of contact members 22a and 22b, a lock mechanism 24, and a hanging jig 26.

(Support member / contact member)
The support member 20 has a U-shape in a plan view. The U-shaped inner diameter of the support member 20 is such that when the paired semi-cylindrical contact members 22a and 22b are arranged so as to face each other with the suspension bolt 14 sandwiched between them, the contact members 22a and 22b The contact members 22a and 22b are set to a width that can be accommodated and a length that allows the contact members 22a and 22b to be arranged at intervals in the longitudinal direction.

The contact members 22a and 22b have a female screw 28 formed on the semi-cylindrical inner surface that comes into contact with the shaft portion 16 of the suspension bolt 14, and are screwed with the male screw 18 of the suspension bolt 14. The abutting members 22a and 22b are arranged in a direction in which the inner surfaces of the support member 20 having female screws 28 formed on one side end and the other side end face each other, and the abutting member 22a and the abutting member 22b are in the axial direction. It is arranged with a gap 30 in between. The gap 30 is adjusted so that the female screw 28 of the abutting member 22a and the female screw 28 of the abutting member 22b can both be screwed into the male screw 18 of the hanging bolt 14. The contact members 22a and 22b and the support member 20 are joined by welding so that they do not separate even when a corresponding load is applied.

The gap 30 between the abutting member 22a and the abutting member 22b is set to a width through which the shaft portion 16 of the hanging bolt 14 can pass, as shown in FIG. 1A in the oblique direction. However, it is preferable that the corners of the contact members 22a and 22b are chamfered 32 and the contact members 22a and 22b are arranged close to each other to make the metal fitting 10 compact as a whole. After the shaft portion 16 of the suspension bolt 14 is diagonally arranged in the gap 30 between the contact member 22a and the contact member 22b (the metal fitting 10 is diagonally arranged with respect to the suspension bolt 14), the contact member 22a, The metal fitting 10 is rotated clockwise so that the female screw 28 of 22b and the male screw 18 of the shaft portion 16 of the hanging bolt 14 are screwed together. At this time, a step 34 is formed so that the shaft portion 16 of the suspension bolt 14 does not interfere with the side surface of the support member 20.

(Lock mechanism)
A lock mechanism 24 is provided at the lower end of the support member 20. The lock mechanism 24 includes a J-shaped member 36, a shaft portion 38 formed perpendicularly to one end of the J-shaped member 36, a rotating member 40 that rotates around the shaft portion 38, and a rotating member 40. It is configured to include an urging means 42 for urging. The J-shaped member 36 is fixed to the support member 20 and the abutting member 22 fixed to the support member 20 by welding or the like. As shown in FIGS. 1 (b) and 2 (b), the J-shaped member 36 emplaces the parallel portion 44 that guides the shaft portion 16 of the suspension bolt 14 and the shaft portion 16 that has been guided by the parallel portion 44. It has an arcuate bottom 46. Therefore, the shaft portion 16 of the suspension bolt 14 is restricted from moving to both sides so as to be guided by the parallel portion 44 of the J-shaped member 36, enters the inside, reaches the bottom portion 46, and stops. The shape of the bottom portion 46 is formed to be larger than the diameter of the female screw 28 of the contact member 22b.

The rotating member 40 that rotates around the rotating shaft portion 38 provided on the J-shaped member 36 has an inclined end portion 48 formed so as to close the parallel portion 44 and a hanging bolt that is stationary on the bottom portion 46. It includes an engaging end portion 50 that is engaged with the shaft portion 16 of 14, and a handle 52 that is manually rotated by an operator. In FIG. 2B, the rotating member 40 is urged by the urging means 42 so as to rotate in the clockwise direction, and is stopped by contacting a part of the J-shaped member 36. There is. Therefore, when the shaft portion 16 of the suspension bolt 14 is brought into contact with the inclined end portion 48 of the rotating member 40 and pushed, the rotating member 40 is rotated counterclockwise against the urging means 42. When the shaft portion 16 of the suspension bolt 14 reaches the bottom portion 46 and stops, the inclined end portion 48 of the rotating member 40 is disengaged from the engagement with the shaft portion 16 of the suspension bolt 14, and is returned to the original position by the urging means 42. The engagement end 50 is engaged with the shaft 16 of the suspension bolt 14. Next, when the operator puts a finger on the handle 52 and rotates the rotating member 40 counterclockwise, the engaging end portion 50 is disengaged from the shaft portion of the hanging bolt 14, and the metal fitting 10 is disengaged. Can be moved diagonally with respect to the hanging bolt 14 and can be removed. The recess 54 formed in the J-shaped member 36 is formed to increase the angle at which the rotating member 40 can be rotated.

(Hanging jig)
As shown in FIG. 1A, a hanging jig 26 is fixed to the side surface of the support member 20 by welding or the like. The hanging jig 26 in this embodiment is used for suspending a duct, wiring, or the like by passing a wire or the like through a large opening 56. The hanging jig 26 is provided at a position where the abutting member 22a and the abutting member 22b are respectively pressed against the shaft portion 16 of the hanging bolt 14 when a load is applied to the hanging jig 26. The screwing between the female screw 28 of the contact members 22a and 22b and the male screw 18 of the shaft portion 16 of the suspension bolt 14 becomes more reliable.

(How to use this metal fitting)
The metal fitting 10 according to the above configuration is attached to a hanging bolt 14 previously installed on the ceiling or the like. Bring the metal fitting 10 to a predetermined position of the hanging bolt 14 to which the metal fitting 10 is to be attached, and apply the metal fitting 10 to the shaft portion 16 of the suspension bolt 14 at an angle. At this time, the shaft portion 16 of the suspension bolt 14 is pushed into the gap 30 between the contact member 22a and the contact member 22b of the metal fitting 10 while adjusting the tilt angle. After confirming that the shaft portion 16 of the suspension bolt 14 has entered the gap 30, the metal fitting 10 is rotated in the vertical direction along the shaft portion 16 of the suspension bolt 14. By this operation, the shaft portion 16 of the suspension bolt 14 and the inclined end portion 48 of the lock mechanism 24 of the metal fitting 10 come into contact with each other, the rotating member 40 is rotated, and the shaft portion 16 of the suspension bolt 14 has a J shape. It reaches the bottom 46 of the member 36. At this time, the female screw 28 of the contact members 22a and 22b of the metal fitting 10 and the male screw 18 of the shaft portion 16 of the suspension bolt 14 are screwed together, and the shaft portion 16 of the suspension bolt 14 is rotated by the lock mechanism 24. It is engaged and locked with the engaging end 50 of the moving member 40. Therefore, even if a force is applied to the metal fitting 10 from all directions, the lock is released and the metal fitting 10 is not dropped from the hanging bolt 14. If the position of the metal fitting 10 is to be slightly moved up and down, the metal fitting 10 can be moved up and down by rotating the metal fitting 10 with respect to the hanging bolt 14. Further, when it is desired to change the position significantly or to remove it, the handle 52 formed on the rotating member 40 of the lock mechanism 24 is rotated so as to be lifted, and the engaging end portion 50 and the shaft portion 16 of the suspension bolt 14 are rotated. By disengaging the engagement with the metal fitting 10, the metal fitting 10 can be immediately removed from the suspension bolt 14.

(effect)
Since this operation can be performed with one touch with one hand, workability is greatly improved even in a narrow space such as the ceiling.

(Other embodiments)
Next, another embodiment according to the present invention will be described. In the following description, the same configurations as those in the above embodiment may be omitted by the same reference numerals.

(Other Embodiment 1)
As shown in FIG. 3, the metal fitting 58 may integrally form the support member 60, the contact members 62a and 62b, and the hanging jig 64. In this case, the metal fitting 58 cuts out a metal block to form a pilot hole in the portion to be the contact members 62a and 62b, and then screw a female screw into the pilot hole. After that, the portion where the gap 66 is formed and the portion of the female screw are cut open so as to be the contact members 62a and 62b. Further, the hanging jig 64 is also integrally formed by cutting. Further, as a locking mechanism, when the metal fitting 58 is attached to the suspension bolt 14, it is arranged at the position of the support member 60 in contact with the shaft portion 16 of the suspension bolt 14, in other words, so as to abut on the inner surface of the contact member 62b. A male screw 68 is inserted at the position of the support member 60 sandwiching the shaft portion 16 in between. That is, after the suspension bolt 14 is screwed into the contact members 62a and 62b of the metal fitting 58, the male screw (projection) 68 is screwed in, and the shaft portion 16 of the suspension bolt 14 is screwed into the shaft portion 69 of the male screw 68. Hold it down so that it does not move in the direction perpendicular to the axis. The metal fitting 58 can be easily removed from the hanging bolt 14 by retracting the male screw 68 so as not to protrude from the support member 60.

In such an embodiment, the male screw 68, which is a locking mechanism, may be used as a slide member (projection), and a resistance member made of rubber, resin, or the like may be provided at a contact portion between the slide member and the support member 60. That is, when the metal fitting 58 is attached to the suspension bolt 14, the slide member is pushed against the resistance force of the resistance member, and the suspension bolt 14 is placed between the shaft portion of the slide member and the contact member 62b of the metal fitting 58. The shaft portion 16 is sandwiched and fixed. Further, when removing the metal fitting 58 from the suspension bolt 14, the slide member can be pulled out so as not to protrude from the support member.

Although it takes time to perform processing such as cutting, the metal fitting 58 is attached to the support member 60 so that the female screw of the contact member 62a and the female screw of the contact member 62b are aligned with each other. Eliminates the hassle of joining.

(Other Embodiment 2)
Next, as shown in FIG. 4, in the metal fitting 86, the support member 88 and the hanging jig 26 are integrally formed of the steel plate by laser machining, punching, etc. at the same time, and the support member 88 is contacted with the contact member. The 90a, 90b and the lock mechanism 24 may be fixed by welding. The abutting members 90a and 90b include a pilot hole in a metal block of a quadrangular prism, tapped on a female screw 28 that can be screwed into a male screw 18 of a hanging bolt 14, and then include an axial center of the female screw 28. Manufactured by cutting on a flat surface. The obtained contact members 90a and 90b are arranged at predetermined positions of the support member 88 and welded and fixed. Further, the lock mechanism 24 has the same configuration as that shown in FIGS. 1 and 2 and is assembled in advance and fixed to the support member 88 by welding or the like.

The metal fitting 86 thus obtained has a smaller number of parts and man-hours for processing as compared with the embodiment shown in FIG. 1 and the like, and can be obtained at low cost. However, the action and effect of the metal fitting 86 is exactly the same as that of the above embodiment.

(Other Embodiment 3)
Further, as shown in FIG. 5, it is also possible to use the hook 92 as a hanging jig. The support member of the metal fitting 94 may be fixed to the side surface of the hook 92 by welding or the like, or the contact members 90a and 90b and the lock mechanism 24 may be directly fixed to the side surface of the hook 92 as the support member. The hook 92 is preferably provided with a chain block (not shown). In this case, if there is no metal fitting for hooking the hook 92 and there is only a hanging bolt 14, the chain block can be attached to the hanging bolt 14 by using the metal fitting 94. The metal fitting 94 is not limited to the hook 92, and the metal fitting 94 may be formed on the side surface of, for example, a C-can.

(Other Embodiment 4)
Further, the hanging jig attached to the metal fitting is not limited to the shape shown in FIG. 1 and the like. For example, as shown in FIG. 6, the hanging jig 80 is provided with a bolt hole in a metal plate 81 integrally formed with a J-shaped member 36 of the lock mechanism 24, and a bolt 82 is passed through the bolt hole with a nut 84. It shall be a screwed configuration. A duct, piping, or the like is attached to the lower end of the bolt 82, and the height is adjusted by loosening the nut 84 and adjusting in the vertical direction.

(Other Embodiment 5)
Further, as shown in FIGS. 7 and 8, L-shaped steel 98 can be used as a support member for the metal fitting 96. Contact members 90a and 90b are fixed to one end of the L-shaped steel 98, and a lock mechanism 100 is provided at the other end. The lock mechanism 100 has a pedestal 104 having a semi-circular inner surface 102 that receives the shaft portion 16 of the suspension bolt 14, and a male screw 106 at one end and a J-shape at the other end in a hole penetrating the pedestal 104. A pressing member 110 on which the pressed pressing portion 108 is formed is provided. A female screw may be formed on the inner surface 102 of the cradle 104.

The metal fitting 96 passes the suspension bolt 14 through the gap 112 between the contact member 90a and the contact member 90b at an angle with respect to the suspension bolt 14, and then passes the L-shaped steel (support member) 98 through the suspension bolt 14. The suspension bolt 14 is sandwiched between the abutting member 90a and the abutting member 90b. Next, the tip end side of the suspension bolt 14 is moved onto the pedestal 104 of the lock mechanism 100, and the shaft portion 16 of the suspension bolt 14 is placed on the inner surface 102. After that, the shaft portion 16 of the suspension bolt 14 is pressed against the inner surface 102 by tightening the nut 112 provided on the male screw 106 by the pressing portion 108 of the pressing member 110. As a result, the metal fitting 96 does not come off from the hanging bolt 14 unless the nut 112 is loosened.

The L-shaped steel (support member) 98 of the metal fitting 96 is provided with a member 114 having a hook shape as shown in FIG. 7 and a U-shaped metal fitting 116 as shown in FIG. 8, and a plurality of pipes or wirings are provided. Can be added.

(Other Embodiment 6)
Next, as shown in FIG. 9, the metal fitting 70 has a configuration in which the female screw 28 is formed only on, for example, the contact member 72a of the contact members 72a and 72b, and the female screw is not formed on the contact member 72b. It is also possible to do. In the above-described embodiment, the female screw 28 is formed on each of the contact members 22a and 22b in order to suspend a heavy object, but in the case of a lightweight object, a female screw is formed on one of the contact members 72a. It may just be formed. The hanging force of the metal fitting 70 is determined by the shearing force of the surface (screwed surface) where the male screw 18 of the hanging bolt 14 and the female screw 28 of the contact member 72a are screwed together. That is, if the area of the semi-cylindrical screw surface is large, the shearing force is large and the hanging force is also large. When the weight of the duct or pipe suspended by the metal fitting 70 is small, for example, the female screw 28 is formed only on the contact member 72a, so that the suspension force can be sufficiently withstood. In this way, for example, by forming the female screw 28 only on the contact member 72a and not forming the female screw on the contact member 72b, the contact member 72b can be formed on the female screw 28 of the contact member 72a. It is not necessary to match the pitch, and the manufacturing cost of the metal fitting 70 can be reduced.

In the metal fitting 70, the hanging force can be increased by increasing the length of the contact member 72a, that is, increasing the length of the female screw 28 of the contact member 72a. Further, since the contact member 72b on which the female screw is not formed only acts to press the shaft portion 16 of the suspension bolt 14, the length may be short. The shaft portion 16 of the suspension bolt 14 is supported by the contact member 72a, the contact member 72b, and the engaging end portion 50 of the lock mechanism 24, and the metal fitting 70 is perpendicular to the axis of the suspension bolt 14. The length of the contact member 72b does not matter as long as it does not move. Further, the female screw may be provided on the contact member 72b without forming the female screw on the contact member 72a.

(Other Embodiment 7)
As for the lock mechanism, when two contact members are brought into contact with the shaft portion 16 of the suspension bolt 14 in the directions facing each other, the shaft portion 16 may be locked by the lock mechanism at the same time and can be alternately supported at three points. The locking mechanism is not limited to the above-described embodiment, and may be configured as shown in FIG. 10, for example. That is, the lock mechanism can be configured by a grip member 74 made of spring steel at one end of the support member 20. The grip member 74 is integrally formed with a grip portion 75 that grips the shaft portion 16 of the suspension bolt 14, and an inclined portion 76 that guides the shaft portion 16 to the grip portion 75 and spreads the grip portion 75. It is configured to include a fixing portion 77 for fixing the 75 and the inclined portion 76 to the support member 20. The fixing portion 77 is preferably fixed to the support member 20 by welding. It is preferable that the shaft portion 16 does not easily come out from the grip portion 75 after the grip portion 75 grips the shaft portion 16 of the suspension bolt 14. Although not shown, for example, it is possible to connect the two inclined portions 76 with a wire or the like to prevent them from expanding, or to make a hole in the connecting portion between the inclined portion 76 and the fixing portion 77 and fasten them through the wire. preferable.

(Other Embodiment 8)
A structure can be made by using the above-mentioned various metal fittings. That is, it is possible to lay ducts, wirings, pipes, etc. arranged on each floor of a building or tunnels of various sizes. By using this metal fitting, the work efficiency of the laying work can be improved, the work schedule can be shortened, and the cost associated with the construction of the structure can be reduced as a whole.
