Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembly-type fixed body fixed to a structure using a rivet fired from a rivet driving machine.
In this specification, the term "stud" refers to a metal nail, a pin, or the like used for fixing a fixed body to a structure.

  For example, as shown in Patent Literature 1, a plurality of (usually two) suspension bolt fixing supports for suspending suspension bolts from a ceiling wall are used to ensure the reliability and stability of the fixing support. There are a large number of fixed bodies that are fixedly supported on the ceiling wall by using studs (metal screws), and are fixed to the structure using a plurality of studs. As described above, in the fixing of the fixed body using the plurality of tacks at a plurality of points, it is a normal design that a portion for securing the tack fixing portion is provided around the main body of the fixed body. There is a disadvantage that the size itself becomes larger than the size of the original functional unit.

  However, when the structure is not made of metal, that is, when the structure is made of concrete, wood, or the like, a crack is generated in a driving portion of the structure due to driving of the stud, and the crack reaches another stud portion. Sometimes. Due to the occurrence of this phenomenon, the fixing strength of the fixed object to the structure by the plurality of tacks is reduced.

  Hereinafter, the present invention will be described in more detail with reference to a plurality of examples.

In the bolt suspender S1 according to the _first embodiment of the present invention, as shown in FIGS. 1 to 10, the fixing pedestal V fixed to the concrete ceiling wall W and the tip of the suspension bolt B are screwed. A nut portion 23 is formed inside, and comprises an assembly main body A integrally assembled with the fixed base V. Both the fixing pedestal V and the assembly main body A are formed by injection molding of resin.

As shown in FIGS. 1 and 2, the fixed pedestal V has an outer diameter slightly smaller on the side of the assembly insertion opening 1 into which the assembly body A is inserted than on the side of the fixing plate 2. An outer peripheral wall portion 3 having a tapered cylindrical shape is provided, and a locked plate portion 4 into which an assembling claw 31 of the assembling main body A is inserted and locked is formed in an opposing portion on the outer peripheral surface of the outer peripheral wall portion 3. The flat wall-shaped relief wall portion 5 has a larger inclination angle than the outer peripheral wall portion 3 and is released outward from the outer peripheral wall portion 3 to protrude from the outer peripheral wall portion 3 and The outer peripheral wall 3 is formed over the entire height. A flat wall-shaped inner wall portion 7a is formed inside the escape wall portion 5 via an escape space portion 6, and the escape wall portion 5 and the inner wall portion 7a are formed in the width direction (the outer wall portion 3). Both ends in the circumferential direction) are connected by a connecting wall 8. Thus, the inner wall portion 7a arranged opposite are parallel to the axis C ₁ of the rivet insertion hole 15 to be described later. An end of each of the inner wall portions 7a on the side of the assembly insertion opening 1 is cut off, and an assembly claw insertion opening for inserting the assembly claw 31 of the assembly main body A into the relief space 6 is provided. It is 11. The mounting claw insertion opening 11 communicates with the lower end of the relief space 6.

  A cylindrical inner peripheral wall portion 7b is provided on the inner side of the outer peripheral wall portion 3 except for the inner wall portions 7a via a stolen space 12. The inner peripheral wall portion 7b is formed only between the fixed plate portion 2 and the intermediate portion of the outer peripheral wall portion 3 in the height direction, and the inner end of the inner peripheral wall portion 7b and the inner periphery of the outer peripheral wall portion 3 are formed. The surface is orthogonal to the surface via the step wall 13. A space formed by the inner wall 7a and the inner peripheral wall 7b of the fixed pedestal V and the relief wall 5 connected to the inner peripheral wall 7b is an insertion arrangement space 14 of the assembly main body A. .

  At the axial center position of the cylindrical inner peripheral wall portion 7b of the fixed plate portion 2, a rivet insertion hole 15 is formed so as to penetrate therethrough. Accordingly, when the fixing pedestal V is fixed using one stud N, the sleeve 16 through which the stud N is inserted is formed concentrically with the stud insertion hole 15. A plurality of rib pieces 17 are formed on the outer circumference of the sleeve 16 along the circumferential direction over the entire height, and a regulating wall 18 is provided outside the respective rib pieces 17 on the back surface of the fixed plate portion 2. When the rivet N is driven into the concrete ceiling wall W by the gas-fired rivet driving machine M, the sleeve 16 and each rib piece 17 are crushed and accommodated in the regulating wall 18. In addition, in FIG. 1 and FIG. 2, before fixing the fixing pedestal V to the concrete ceiling wall W with the studs N, 19 holds the fixing pedestal V so as not to be laterally displaced with respect to the concrete ceiling wall W. 5 shows a plurality of slip-off preventing projections formed to protrude from the upper surface of the fixed plate portion 2.

  As shown in FIGS. 5 and 6, the distal end portion of the firing cylinder 51 of the gas-fired riveting machine M is fitted to the outside of the plurality of rib pieces 17 provided outside the sleeve 16, whereby the firing is performed. Concentricity between the cylinder 51 and the sleeve 16 is ensured. The studs N supplied one by one to the firing cylinder 51 are inserted into the sleeve 16, and in this state, the impact force of the impact rod 52 slidably fitted inside the firing cylinder 51 causes the sleeve N to be pressed. The ribs 16 and the rib pieces 17 are integrally crushed and the studs N are driven into the concrete ceiling wall W. Here, the reason why the sleeve 16 is integrally provided on the back surface side of the fixed plate portion 2 is that the sleeve 16 and each rib piece 17 outside the sleeve 16 are crushed by the impact force of the impact rod 52 generated by the combustion pressure of the gas. When the impact force is directly applied to the fixed plate portion 2 without the sleeve 16, the fixed plate portion 2 is damaged or cracked, thereby fixing the fixed plate portion 2. This is to prevent the product value of the pedestal V from being lost.

  At the end of the outer peripheral surface of the outer peripheral wall 3 on the side of the fixed plate 2, a pair of flanges 10 separated by a pair of opposed relief walls 5 is formed to protrude outward. , Both ends of which are connected to the connecting wall 8. The upper end surfaces of the relief wall portion 5 and the connection wall portions 8 are arranged on the same plane as the upper surfaces of the fixing plate portion 2 and the pair of flange portions 10, and are used when fixing the fixing pedestal V to the concrete ceiling wall W. Is brought into close contact with the wall surface of the concrete ceiling wall W.

Further, as shown in FIG. 2A, the inner surface of each inner wall portion 7a is provided with an elastic piece of the assembly main body A so that the assembly main body A can be inserted and arranged in the insertion arrangement space 14 of the fixed base V. It is formed on the inclined surface 7a ₁ corresponding to the inclined with respect to the axis C ₂ of the nut portion 23 of 22. The inner end surface of the locked plate portion 4 is formed outside the elastic piece 22 of the assembly main body A when the assembly main body A is inserted into the insertion arrangement space portion 14 of the fixed pedestal V and assembled. assembled pawl 31 is in elastic contact, the elastic piece 22 in order to elastically deform, it is an inclined inner end face 4a inclined to the inclined face 7a ₁ and the same direction.

  Further, the pair of locked plate portions 4 of the fixed pedestal V is locked with the assembling claws 31 of the mounting body A, and the pair of locked plate portions 4 are attached to the outer peripheral wall of the fixed pedestal V by the outer peripheral wall. The escape wall portions 5 are disposed at the lower ends of the pair of escape wall portions 5 disposed so as to protrude outward from the portion 3 so as to be easily recognized from the outside. It becomes a recognition index of. For this reason, as shown in FIG. 7, the mounting body A screwed to the tip of the suspension bolt B against the fixed pedestal V fixed to the concrete ceiling wall W is pressed from directly below the fixed pedestal V. When assembling the fixed base V, the position of the locked plate portion 4 can be recognized by the position of each relief wall portion 5 which protrudes greatly to the outer peripheral wall portion 3 of the fixed base V. The assembly main body A can be easily assembled to the fixed pedestal V without rotating the assembly main body A with respect to the fixed pedestal V and searching for a locking position in the circumferential direction.

On the other hand, as shown in FIGS. 3 and 4, the assembling main body A is configured such that the small-diameter peripheral wall portion 21 a and the large-diameter peripheral wall portion 21 b are displaced in the axial direction and are integrated with each other on the outer peripheral surface of the peripheral wall portion 21. A pair of elastically deformable thick plate-like elastic pieces 22 are formed integrally with each other so as to protrude outwardly, and a cylindrical nut portion is formed inside the peripheral wall portion 21 so as to be concentric with the peripheral wall portion 21. 23 is formed integrally with the peripheral wall portion 21, and the assembly main body A is configured to be inserted into the insertion arrangement space portion 14 of the fixed pedestal V from the side of the small-diameter peripheral wall portion 21 a. Planar outer surface of the elastic piece 22, corresponding to the inclined surfaces 7a ₁ of the inner surface of the inner wall portion 7a of the fixing base V, is an inclined surface 22a which is inclined by the same angle. The half on the insertion side where the nut portion 23 is divided into two along the insertion direction of the assembling main body A is a small-diameter peripheral wall portion via a connecting plate portion 24 at a portion where a pair of elastic pieces 22 are arranged facing each other along the circumferential direction. An end of the nut 23 on the side opposite to the insertion side is connected to the large-diameter peripheral wall 21b by forming a digging space 25 outside the nut. An end surface of the nut portion 23 on the insertion side of the assembly main body A is disposed at the same position as one end surface of the peripheral wall portion 21. However, an end portion of the nut portion 23 on the side opposite to the insertion side of the assembly main body A is A guide surface 26 having a shape of a hollow inverted truncated cone that guides a distal end portion of the suspension bolt B screwed into the nut portion 23 is formed so as to greatly enter the other end surface of the peripheral wall portion 21. In FIG. 4, reference numeral 27 denotes a meat stealing space formed in a portion of the large-diameter peripheral wall portion 21b corresponding to an arrangement position of the small-diameter peripheral wall portion 21a along the radial direction.

Said portion of the pair of elastic pieces 22 in the large-diameter circumferential wall portion 21b is disposed, said that the larger cut away in a planar shape so as to be parallel to the axis C ₂ of the nut portion 23, cutout surface 28 Is formed, and a space between each of the notch surfaces 28 and each of the elastic pieces 22 is an elastic deformation space portion 29 that enables the elastic piece 22 to be elastically deformed. On the outer surface of each of the thick plate-like elastic pieces 22, an assembling claw 31 functioning as a locking claw is formed along the width direction of the elastic piece 22 (the tangential direction of the small-diameter peripheral wall portion 21a).

The end surface of the cylindrical nut portion 23 on the thread groove end side (the side opposite to the screwing start end side with respect to the suspension bolt B) is screwed (rotated in a screwed state) with respect to the nut portion 23. , that hanging bolt B in that the hanging bolts B proceeds in the direction of the axis C ₂₎ reaches the screw groove end portion, a plurality of sensing projections 32 to be sensed by the operator, screw groove of the nut portion 23 23a.

Next, with reference to FIGS. 5 to 10, with a lowering device S ₁ hanging bolts mentioned above, it will be described operation of supporting suspended bolts B suspended concrete ceiling wall W. First, as shown in FIGS. 5 and 6, when the fixing plate portion 2 of the fixing pedestal V is pressed against the wall surface Wa of the concrete ceiling wall W, a plurality of slip prevention projections 19 protruding from the upper surface of the fixing plate portion 2. All or a part of them enters into the gap of the concrete aggregate facing the wall surface Wa and does not laterally shift. In this state, as described above, when the stud N is impacted into the concrete ceiling wall W using the gas-fired stapler M, the cylindrical sleeve 16 and the plurality of rib pieces 17 on the outer peripheral surface thereof are formed. The crushed lumps 20 are housed inside the regulating wall 18 (see FIG. 8). Since the sleeve 16 and the plurality of rib pieces 17 on the outer peripheral surface thereof are crushed into a crushed mass 20, the impact force of the impact rod 52 on the fixed plate portion 2 at the time of driving the rivet N is reduced. As described above, the fixing plate 2 can be prevented from being damaged or cracked. The head Na of the stud N bites into the crushed mass 20 to be integrated.

  As a result, the fixing pedestal V is fixed to the concrete ceiling wall W by one stud N, and the driving of the stud N into the concrete ceiling wall W by the gas-fired stapling machine M pushes the concrete rapidly to the surroundings. The perimeter of the driven stud N is tightened by the reaction force that is inserted and the concrete tries to return to the original state, so that the stud N is fixed to the concrete with a large tightening force. The fixing pedestal V is held on the main body of the stud N by the head Na of the stud N. In addition, since it is fixed by one stud N, it is not affected by a crack generated in the concrete due to the driving of another stud N, and the fixing pedestal V is fixed to the concrete ceiling wall W by only one stud N. And can be fixed firmly. The fixing work of the fixing pedestal V to the concrete ceiling wall W is performed by an operator climbing on a stepladder.

  Next, the assembly body A is screwed to the tip of the suspension bolt B by relatively rotating the suspension bolt B and the assembly body A at hand of the worker. Here, when the suspension bolt B and the assembly main body A are relatively rotated, and the tip end of the suspension bolt B reaches the thread groove end side of the nut section 23 of the assembly main body A, the nut section 23 is rotated. The tip of the hanging bolt B being screwed into contact with one of the plurality of sensing projections 32 abruptly increases the force required for rotating the hanging bolt B. By recognizing that B has reached the screw groove end of the nut portion 23, the screwing operation of the hanging bolt B can be stopped. As a result, the mounting body A is attached to the tip of the suspension bolt B by screwing, without the suspension bolt B protruding greatly from the thread groove end side of the nut portion 23 of the mounting body A. For this reason, the protrusion length of the suspension bolt B from the thread groove end side of the nut portion 23 is longer than the limit value, and the suspension bolt B is fixed to the fixed base V fixed to the wall surface Wa of the concrete ceiling wall W. When the assembly main body A screwed to the distal end portion is pressed and assembled, a situation in which the assembly cannot be performed can be prevented in advance. The plurality of sensing projections 32 are destroyed by further screwing the suspension bolt B with respect to the assembly main body A with a large rotational force.

Next, as shown in FIG. 7 and FIG. 8, the worker D climbs up to the stepladder K while holding the hanging bolt B having the assembly body A screwed to the tip portion with one hand, and the concrete When the mounting main body A is pressed against the fixing pedestal V fixed to the ceiling wall W, each of the mounting claws 31 formed on the outer surface of each of the elastic pieces 22 of the mounting main body A is displaced. When it reaches the mounting claw insertion opening 11 in a state of being elastically deformed inward by being elastically in contact with the inclined inner end surface 4a of the locking plate portion 4, each of the mounting claws 31 is brought into the original shape by the elastic restoring force. And enters the lower end of the relief space 6 and is disposed between the opposed connecting wall portions 8 and above each locked plate portion 4, and in a state where the assembled body a is not rotated around the axis C ₂ of the nut portion 23, each of the engageable with each assembly pawl 31 A plate portion 4 are locked to each other. In addition, when assembling the assembly main body A to the fixed pedestal V, it is necessary to match the circumferential phases of the locked plate portion 4 of the fixed pedestal V and the assembly claw 31 of the assembly pedestal A. The worker can easily recognize from the appearance that each relief wall 5 of the fixed pedestal V protrudes largely outward with respect to the outer peripheral wall 3. It is easy. Thereby, the assembly main body A is housed in the insertion arrangement space portion 14 of the fixed pedestal V, and the assembly main body A is integrally assembled with the fixed pedestal V fixed to the concrete ceiling wall W. When the hanging bolt B is further rotated with respect to the assembling main body A after the assembling, all of the plurality of sensing protrusions 32 whose leading end surfaces of the hanging bolt B are in contact with each other are broken, and The hanging bolts B press the head Na of the studs N, and the respective mounting claws 31 of the mounting main body A press the upper surfaces of the respective locked plate portions 4 of the fixed pedestal V. The mounting main body A cannot move up and down with respect to the fixed pedestal V, and the mounting state of the two becomes strong.

In this way, the worker places the assembly body A screwed to the tip of the suspension bolt B directly below the fixing pedestal V previously fixed to the concrete ceiling wall W or in the vicinity thereof. The suspension bolts B are suspended from the concrete ceiling wall W only by pressing against the fixing pedestal V, and the suspension bolts B are fixed to the bolt holders fixed to the wall surface Wa of the concrete ceiling wall W as in the related art. Does not need to be directly rotated and screwed, so that the suspension bolt B can be easily suspended from the concrete ceiling wall W. It should be noted that before the mounting body A is pressed, the mounting position of the mounting body A with respect to the fixed pedestal V is not immediately below the fixed pedestal V, but is in the vicinity of the fixed pedestal V. of the inclined surface 22a of the outer surface, it is guided by the inclined surfaces 7a ₁ of the inner surface of the inner wall 7a of the fixing base V, that is housed within the insertion arrangement space portion 14 of the fixing base V, the assembled body a Since each of the mounting claws 31 provided on each of the elastic pieces 22 is locked to each of the locked plate portions 4 of the fixed pedestal V, the mounting by pressing the mounting body A against the fixed pedestal V is easy. . As shown in FIG. 9, in a state where the mounting main body A is mounted on the fixed pedestal V, the small-diameter peripheral wall portion 21a and the large-diameter peripheral wall portion 21b of the mounting main body A are respectively fixed to the fixed pedestal V The inner peripheral wall 7b and the outer peripheral wall 3 are accommodated and arranged inside, and the step between the small-diameter peripheral wall 21a and the large-diameter peripheral wall 21b is disposed immediately below the step wall 13 of the fixed base V. .

Then, as shown in FIG. 10, the pipe P ₁ is horizontally arranged at a portion close to the concrete ceiling wall W from a plurality of suspension bolts B suspended from the concrete ceiling wall W by the bolt suspenders S _1. Supported. The pipe P ₁ is supported on the lower end of the suspension bolt B via a pipe support 61 and a double nut 62. The fixing pedestal V constituting the bolt suspender S ₁ is fixed to the wall surface Wa of the concrete ceiling wall W with one stud N, and the suspending bolt B is suspended from the bolt suspender S ₁ . Since the fixing position along the circumferential direction of the fixing pedestal V fixed to the wall surface Wa by one stud N may be any position, the fixing operation of the fixing pedestal V to the wall surface Wa becomes easy.

  In the first embodiment, the entire assembly main body A is inserted and arranged in the insertion arrangement space portion 14 of the fixed pedestal V. Therefore, the assembly main body A itself constitutes an “insertion main body part” in claim 1.

Next, a description will be given of a wiring and piping material holder S2 according to a _second embodiment of the present invention with reference to FIGS. Wiring and piping material holder S ₂ consists of the fixed base V, and the holder body E to be assembled with respect to the fixed base V. The holder main body E is formed by bending a plate having a constant width into a U-shape by injection molding of a resin, so that a pipe insertion opening 41 is formed. A pair of elastic pieces 43 are formed to face each other, and a mounting claw 44 is formed outside the elastic pieces 43 over the entire width. Each elastic piece 43 is formed to be narrower than the holding body 42 and is integrally connected at the center of the holding body 42 in the width direction.

The holding body 42 has a shape in which the holding wall portions 42b are formed integrally with the opening of the semi-cylindrical portion 42a in parallel with each other, and the elastic pieces 43 integrally connected to the holding wall portions 42b. Are inclinedly arranged so that the width gradually decreases toward the pipe insertion opening 41. Therefore, the width U ₁ of the pipe insertion opening 41 is formed to be smaller than the width U ₂ of each holding wall portion 42b of the holding body 42, and the pipe P corresponding to the semi-cylindrical portion 42a of the holding body 42 from the pipe insertion opening 41. when inserting a _2, a pair of elastic pieces 43 is elastically deformed outward, after the pipe P ₂ is inserted into the holding member 42 is restored to the original shape.

Then, as shown in FIG. 12, the fixing base V is fixed to the wall surface Wa of the concrete ceiling wall W with only one stud N using the gas-fired stitching machine M in the same manner as in the first embodiment. after, while supporting the pipe P ₂ in the holder 42, the holder main body E directly under the relevant fixing base V, is pressed against the fixing base V. As a result, the pair of elastic pieces 43 of the holder main body E are inserted and arranged in the insertion arrangement space portion 14 of the fixed base V, and the pair of elastic pieces 43 of the holder main body E are slightly elastically deformed inward. Later, by restoring the original shape, each of the assembling claws 44 provided outside the pair of elastic pieces 43 of the holder main body E passes through the respective assembling claw insertion openings 11 of the fixed pedestal V, and the outer peripheral wall 3 And between the connecting wall portions 8 connecting the escape wall portion 5 and the outer peripheral wall portion 3 which are arranged to escape to the outside, and above the locked plate portion 4. The assembly claws 44 and the locked plate portions 4 are locked to each other. Thereby, the holder main body E is integrally attached to the fixed pedestal V fixed to the wall surface Wa without rotating relative to each other.

  In the second embodiment, the portion of the pair of elastic pieces 43 of the holder main body E inserted and arranged in the insertion arrangement space 14 of the fixed pedestal V constitutes the “insert main body”.

In each of the first and second embodiments, the number of the studs N for fixing the fixed pedestal V to the concrete ceiling wall W is only one, and is disposed at the center of the fixed plate portion 2 of the fixed pedestal V. Since the mounting main body A or the holder main body E is integrally mounted on the fixing pedestal V, the studs N are concealed inside, so that the appearance is improved and the bolt suspender having the fixing pedestal V is provided. the size of S ₁ or the wiring and piping material holder S ₂ is an inherently required size, it is not necessary to secure an extra space for placing the tacks N, bolt hanger device S ₁ or the wiring and piping material holder S ₂ does not increasing the size of the waste.

  In the first and second embodiments, the structure to which the assembly-type fixing body is fixed is a concrete ceiling wall. However, the structure can be fixed to a concrete side wall, a concrete floor wall, or the like.

Further, in the above Examples 1 and 2, the fixing base constituted by a single rivet N emitted from the gas combustion type tacker M, bolt hanger device S ₁ or the wiring and piping material holder S ₂ V Is fixed to the concrete ceiling wall W, but the target (base material) to which the assembly-type fixed body according to the present invention is fixed is not limited to the concrete wall, but is driven in relation to the base material. Provided that the required fixing strength of the studs can be ensured, the studs can also be fixed to a thin metal plate, brick, concrete block, or the like that constitutes the lightweight steel with one stud. In particular, when the object to be fixed is a thin metal plate, even if the rivet is driven, no crack is generated around the rivet, so that the fixing can be performed with only one rivet with a large fixing force.

As for the “assembly-type fixed body” that is fixed to a structure with one rivet, a fixing pedestal that is fixed to the structure with one rivet and an assembly that is integrally assembled to the fixing pedestal It is not limited to the bolt suspender S ₁ and the wiring / piping material holder S ₂ of the _first and second embodiments as long as it comprises a main body, and may be a fixed body for any use.

  In the first and second embodiments, the concentricity between the sleeve 16 of the fixed pedestal V and the firing cylinder 51 of the gas-fired stapler M is ensured by the plurality of rib pieces formed on the outer peripheral surface of the sleeve 16. 17 is used, but the firing cylinder 51 is externally or internally fitted to an annular regulating wall 18 provided on the outside of the sleeve 16 in the fixed plate portion 2 of the fixed base V, so that the firing on the sleeve 16 is performed. The concentricity of the cylinder 51 may be ensured.
