  In the present invention, a cross member is attached to a scaffold for attaching a cross member such as a handrail, a crosspiece or a baseboard, which is a safety equipment of the scaffold, and the cross member is attached using the cross member attachment bracket. Related to the scaffolding.

  Conventionally, when a handrail is added to a scaffold in which a rectangular parallelepiped frame is formed by bracing with a gate-shaped building frame and a steel scaffolding board, a metal fitting attached to a pedestal (building land) of the building frame is known. (See Patent Documents 1 and 2).

  In addition, as disclosed in Patent Documents 3 and 4, a metal fitting to be attached to attach a baseboard to a side edge of a scaffold plate is also known.

  Further, Patent Document 5 discloses a metal fitting for newly attaching a crosspiece using an existing bracing.

  In other words, the existing building frame is provided with protrusions such as lock pins for attaching braces, but there are no extras other than bracing, so try to add cross members such as handrails and baseboards. In this case, it is necessary to newly mount a metal fitting for attaching the cross member.

  On the other hand, in order to improve the safety of the scaffold, there is a movement to regulate the addition of handrails, baseboards, crosspieces, etc. in addition to the braces and handrails conventionally attached.

  However, although the metal fitting disclosed in Patent Document 1 is configured to mount the metal fitting using a lock pin for bracing, the lower end of the long metal fitting is fixed to the pedestal by the fastening force of the fixing screw. Since it is configured, it is necessary to strongly tighten the fixing screw, which may damage the pedestal. Moreover, if the fixing screw is loosened, the lower end of the metal fitting may turn around the pedestal and rattle.

  In addition, the metal fittings disclosed in Patent Documents 2, 3, and 4 do not have a structure that suppresses the rotation of the metal fittings, and the play of the hole through which the lock pin is inserted is large, or the U-shaped clamping means is loose. Otherwise, there is a risk of rattling.

  Furthermore, since the metal fitting disclosed in Patent Document 5 is attached in the middle of the brace, a handrail or a baseboard cannot be attached at a position lower than the brace.

  Therefore, an object of the present invention is to provide a cross member mounting bracket that can be easily mounted and has excellent stability, and a scaffold to which the cross member is mounted using the cross member mounting bracket.

As shown in FIGS. 3 and 5, the gripping metal 181 is hooked on the horizontal member 12 of the lower building frame 10 to form an upper floor surface. In addition, as shown in FIG.3 and FIG.2, the two scaffold boards 18 and 18 from which width differs are spanned between the building frames 10 and 10 in parallel.

  Moreover, between the building frames 10 and 10 arrange | positioned at intervals at the long side, as shown in FIG. 2, the braces 13 and 13 are bridged in X shape. Further, below the braces 13, 13, the handrail 2 </ b> A and the baseboard 3 </ b> A as cross members are bridged between the building frames 10, 10 in parallel to the scaffolding plate 18 using the handrail skirting metal fittings 4, 4 </ b> A. .

  Further, as shown in FIG. 3, below the stiffeners 16, 16 of the building frame 10 arranged at the end in the long side direction of the scaffold 1, a cross member using handrail skirting metal fittings 4, 4 is used. The handrail 2 </ b> B and the baseboard 3 </ b> B are bridged between the pillars 11 and 11 in parallel with the horizontal member 12.

  In addition, although it named as handrail 2A, 2B here, what is called a crosspiece, such as a lower rail, is included in this handrail 2A, 2B.

  Further, as shown in FIG. 4, a lock pin 14 for attaching a lower end portion of the braces 13, 13 protrudes horizontally on the pedestal 11 toward the short side direction. That is, as shown in FIG. 3, the lock pins 14, 14 provided on the pedestals 11, 11 erected in parallel are each extended toward the inside of the building frame 10. Moreover, the upper end part of the braces 13 and 13 is attached to the lock pin 14A protruded from the upper part of the pedestal 11 as shown in FIG.

  At the tip of the lock pin 14 (14A), a triangular lock claw 141 that moves in and out by the biasing force of the spring is provided as a lock mechanism, and the hole at the end of the brace 13 is inserted into the lock pin 14. It is possible to prevent the dropout after installation.

  And the handrail skirting board metal fitting 4 of this embodiment is attached to this lock pin 14. As shown in FIG. 1, the handrail skirting metal fitting 4 includes a long plate-like main body 41, support holes 43 and 43 </ b> A drilled in the main body 41 for inserting the lock pin 14, and the main body 41, an engaging portion 42 provided at the lower end of the body 41, handrail mounting pins 44A and 44B as lateral member mounting pins protruding from the main body portion 41 for mounting the handrails 2A and 2B, and a baseboard protruding from the main body portion 41 Baseboard mounting pins 45A, 45B, 46A, and 46B as cross member mounting pins for mounting 3A and 3B are provided.

  1 is mounted on the right pedestal 11 shown in FIG. 3, and the handrail skirting metal fitting 4 mounted on the left pedestal 11 shown in FIG. The handrail mounting pin 44B and the baseboard mounting pins 45B and 46B protrude from the opposite side surface of the main body 41. Further, as shown in FIG. 2, only the handrail mounting pin 44 </ b> A and the baseboard mounting pins 45 </ b> A and 46 </ b> A are included in the main body 41. The handrail mounting pin 44B and the baseboard mounting pins 45B and 46B are omitted.

  As shown in FIG. 4, the main body 41 is a member extending along the pedestal 11, and the lock claw 141 and the brace 13 of the lock pin 14 to which the ends of the two braces 13 and 13 are attached. It is formed to a thickness that can be interposed between the two.

  In addition, two support holes 43 and 43A are provided here because the position of the lock pin 14 differs depending on the type of the building frame 10, and thus the handrail skirting metal fitting 4 (4A) has two types. It is possible to correspond to the height of the lock pin 14. Here, the support hole 43 is for a lock pin provided at a height of about 330 mm from the upper surface of the horizontal member 12, and the support hole 43A is a lock provided at a height of about 240 mm from the upper surface of the horizontal member 12. For pins.

  Further, an insertion port 47 is made to penetrate at a position facing the key lock 17 of the main body portion 41 so as to correspond to the building frame 10 of a type in which a protrusion such as the key lock 17 is provided on the pedestal 11. .

  Further, as shown in FIG. 1, the engaging portion 42 is a sliding member as a fixing means for suppressing the occurrence of relative displacement between the cover portion 421 formed in a gate shape and the cover portion 421 and the horizontal member 12 covering the cover portion 421. And a set bolt 422.

  The cover portion 421 is formed with three surfaces surrounding the upper surface and both side surfaces of the cylindrical horizontal member 12 in a gate shape, and the penetration direction of the cover portion 421 is the penetration direction of the support holes 43 and 43A. Becomes parallel.

  As shown in FIG. 5, when the handrail skirting metal fitting 4 is attached to the lock pin 14 of the pedestal 11, three orthogonal inner surfaces of the cover portion 421 come into contact with the horizontal member 12 at three locations. .

  Further, the non-slip bolt 422 is a means for adjusting the amount of protrusion of the cover portion 421 toward the inner surface side by rotation and suppressing the occurrence of relative displacement by pressing the tip against the side surface of the horizontal member 12. Here, since the cover portion 421 has a stable mounting performance that comes into contact with the horizontal member 12 at three locations, the pressing force by the anti-slip bolt 422 may not be so great.

  Further, the handrail mounting pins 44A and 44B protruding from above the support hole 43 of the main body 41 are protruded in two directions, that is, a through direction of the support hole 43 and a direction perpendicular thereto.

  The lock pin 14 to be inserted into the support hole 43 is originally provided for mounting the long side braces 13, 13, and is a handrail mounting pin protruding so as to be parallel to the lock pin 14. 44A is also used for attaching the handrail 2A on the long side.

  Further, the handrail mounting pin 44B protruding in a direction orthogonal to the handrail mounting pin 44A in the horizontal plane is used for mounting the handrail 2B on the short side. Further, a lock claw 141 similar to the lock pin 14 is provided as a lock mechanism at the tips of the handrail mounting pins 44A and 44B.

  And since these handrails 2A and 2B are bridge | crossed in the position lower than the cross | intersection part of the braces 13,13 or the wife handrail 15, the gap between the braces 13,13 or the wife handrail 15 and the scaffold board 18 may be interrupted. It is possible to prevent the worker from falling from the meantime. For example, the handrail mounting pins 44 </ b> A and 44 </ b> B are provided at a height of about 390 mm from the upper surface of the horizontal member 12.

  Moreover, as shown in FIG. 5, a pair of baseboard attachment pins 45A and 46A provided at intervals in the longitudinal direction (vertical direction) of the main body 41 are used for attaching the baseboard 3A on the long side. .

  Furthermore, the baseboard mounting pins 45B and 46B protruding in a direction orthogonal to the baseboard mounting pins 45A and 46A in the horizontal plane are used for mounting the baseboard 3B on the short side. Further, a lock claw 141 similar to the lock pin 14 is provided as a lock mechanism at the tips of these baseboard mounting pins 45A, 45B, 46A, 46B.

  Since these baseboards 3A and 3B are erected on the side edges of the scaffolding plate 18, it is possible to prevent materials, parts and the like on the scaffolding plate 18 from falling.

  Next, the effect | action of the handrail skirting board combined use metal fitting 4 of this Embodiment is demonstrated.

  The handrail skirting board / metal fitting 4 (4A) of the present embodiment configured as described above includes a support hole 43 through which the lock pin 14 is inserted, and a gate-shaped cover that covers the horizontal member 12 at the lower end of the main body 41. An engagement portion 42 provided with a cover portion 421 is provided.

  For this reason, if the cover 421 is placed on the horizontal member 12 and the handrail base metal fitting 4 is slid in the direction of the pedestal 11, the lock pin 14 protruding from the pedestal 11 is easily inserted into the support hole 43. Can be attached to.

  That is, the lock pin 14 is provided with a lock claw 141 that does not become a resistance when inserted in the direction of the pedestal 11 but serves as a stopper for movement in a direction away from the pedestal 11. By simply inserting the support hole 43 of the main body portion 41 into the lock pin 14, the handrail skirting metal fitting 4 can be attached to the scaffold 1.

  Further, as shown in FIG. 5, since the portal cover portion 421 is placed on the horizontal member 12 so as to straddle, it is orthogonal to both the longitudinal direction of the main body 41 and the axial direction of the horizontal member 12. The movement in the direction (the direction orthogonal to the axis in the horizontal plane of the horizontal member 12) is limited only by covering the horizontal member 12 with the cover portion 421.

  Furthermore, the movement of the engaging portion 42 in the axial direction of the horizontal member 12 can also be limited by turning and tightening the anti-slip bolt 422. With respect to the movement in this direction, the three contact points between the horizontal member 12 and the inner surface of the cover portion 421 also become a resistance, so that the force of pressing the tip of the anti-slip bolt 422 against the horizontal member 12 is large. The height does not need to be so large, and there is almost no possibility of damaging the horizontal member 12 by the force. The movement of the engaging portion 42 in the axial direction of the horizontal member 12 is also restricted by the gripping metal 181 of the scaffold plate 10.

  Further, the upper portion of the main body 41 is supported by the lock pin 14 through the support hole 43, and the lower end of the main body 41 is supported by the engaging portion 42 having excellent stability to be placed on the horizontal member 12. The handrail skirting board metal fitting 4 is hardly rattled after being mounted.

  Further, since the handrail mounting pins 44A and 44B and the baseboard mounting pins 45A, 45B, 46A and 46B are projected in two orthogonal directions, the handrail 2A is formed on the long side and the short side of the scaffold 1 in two directions. , 2B and baseboards 3A, 3B can be added.

  Further, by providing handrail mounting pins 44A and 44B on the upper portion of the main body 41 and providing baseboard mounting pins 45A, 45B, 46A and 46B near the lower end of the main body 41, two kinds of horizontal positions are provided. Material can be attached.

  Furthermore, if a plurality of support holes 43, 43A are provided at intervals in the longitudinal direction of the main body 41, the support holes 43, 43A should be mounted on various types of building frames 10 with different heights at which the lock pins 14 are projected. And versatility can be expanded.

  Moreover, if it is the structure which mounts the handrail skirting board metal fitting 4 together with the braces 13 and 13 attached to the lock pin 14, the rigidity as designed is obtained without changing the number and positions of the existing braces 13 and 13. Therefore, there is no possibility of reducing the rigidity of the scaffold 1 by adding handrails or baseboards.

  Furthermore, since the handrail mounting pins 44A and 44B are provided at positions different from the support holes 43 into which the lock pins 14 are inserted, the handrails 2A and 2B are newly provided at an arbitrary height different from the mounting position of the brace 13. Can be added.

  Hereinafter, a handrail-dedicated metal fitting 5 as a metal fitting for mounting a cross member in a form different from the above-described embodiment will be described with reference to FIGS. The description of the same or equivalent parts as those described in the above embodiment will be given the same reference numerals.

  The handrail fitting 5 of this embodiment has a rectangular plate-shaped main body 51, a support hole 53 drilled in the main body 51 for inserting the lock pin 14, and an engagement provided at the upper end of the main body 51. A portion 52, an auxiliary engagement portion 55 provided at the lower end of the main body 51, and a handrail mounting pin 54 as a cross member mounting pin that protrudes from the main body 51 and attaches the handrail 2A as a cross member. ing.

  On the front surface of the main body 51, a handrail mounting pin 54 protrudes upward in the direction perpendicular to the plane, and a support hole 53 is drilled in the lower part.

  As shown in FIG. 7, the lock pin 14 inserted through the support hole 53 is originally provided for mounting the long side braces 13, 13 and is parallel to the lock pin 14. The handrail attaching pin 54 protruding to the side is also used for attaching the handrail 2A on the long side of the scaffold 1.

  The engaging portion 52 is provided at the upper end portion of the main body portion 51 and is formed so as to surround the pedestal 11 together with the back surface of the main body portion 51. That is, a pair of upper end side plates 521 and 521 extend from the upper end side edge of the back surface of the main body 51 in the direction orthogonal to the back surface, and an openable and closable engagement bar 522 is bridged between the portions facing the main body 51. It is.

  The upper side plate 521 is a rectangular steel plate as shown in FIG. 8 and is longer than the sum of the thickness of the two braces 13 and 13, the diameter of the pillar 11, and the diameter of the engagement bar 522. ing.

  A hole 521a through which the engagement bar 522 is inserted is perforated at a position separated from the back of the main body 51 of the upper end side plate 521 by a length obtained by adding the thickness of the two braces 13 and 13 and the diameter of the pedestal 11. Has been.

  Furthermore, the engagement bar 522 is provided with, for example, locking claws 141 at both ends as a drop-off prevention mechanism. The engagement bar 522 is inserted from the hole 521a of one upper end side plate 521, and the other upper end side plate 521 is inserted. By projecting the tip provided with the lock claw 141 from the hole 521a, a rectangular frame surrounding the pedestal 11 is formed.

  The auxiliary engagement portion 55 is provided at the lower end portion of the main body portion 51 and is formed so as to surround the pedestal 11 in a substantially U shape in plan view together with the back surface of the main body portion 51. That is, as shown in FIG. 6, a pair of lower end side plates 551 and 551 extend from the lower end side edge of the back surface of the main body 51 in the direction orthogonal to the back surface.

  Since the upper side plate 521 and the lower side plate 551 are open as shown in FIGS. 6 and 8, even if the braces 13 and 13 are attached to the lock pin 14, they are shown in FIGS. Thus, the attachment can be performed without interfering with the handrail-dedicated metal fitting 5.

  As described above, the handrail metal fitting 5 of the embodiment includes the engaging portion 52 and the auxiliary engaging portion 55 at the end portion of the main body portion 51 in the vertical direction. The engaging portion 52 is formed so as to surround the leg column 11 in a square shape in a plan view, and the auxiliary engaging portion 55 is formed so as to surround the leg column 11 in a U shape in a plan view.

  That is, in addition to the support hole 53 through which the lock pin 14 is inserted, two places are engaged to suppress the rotation with respect to the pillar 11, and the upper end of the handrail dedicated bracket 5 is engaged to be separated from the pillar 11. Since it is blocked by the bar 522, the stability after mounting is excellent, and the occurrence of rattling can be suppressed.

  Further, since the engaging portion 52 is formed by an insertion-type openable / closable engaging bar 522 that does not use a bolt, there is no possibility that loosening occurs when the engaging portion 52 is tightened with a bolt.

  Furthermore, since the handrail bracket 5 is mounted together with the brace 13 and 13 attached to the lock pin 14, it is not necessary to change the number and position of the existing brace 13 and 13, and the rigidity of the scaffold 1 is reduced. There is no fear.

  Further, since the handrail attaching pin 54 is provided at a position different from the support hole 53 into which the lock pin 14 is inserted, the handrail 2A can be provided at an arbitrary height different from the attachment position of the brace 13.

  Furthermore, when the net for preventing the fall of the object is stretched on the scaffold 1, the fall of the object can be prevented without attaching the baseboards 3A and 3B. Therefore, by using the handrail bracket 5 having a simple configuration, Only the handrail 2A can be added easily and economically.

  Other configurations and operational effects are substantially the same as those in the above-described embodiment, and thus description thereof is omitted.

  The embodiments and examples of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to the embodiments and examples, and the gist of the present invention is not deviated. Design changes are included in the present invention.

  For example, in the said embodiment, although the support holes 43 and 43A were provided in two places, it is not limited to this, According to the height of the lock pin 14 of the building frame of the scaffolding with which mounting | wearing is assumed One or three or more locations may be used.

  In the above embodiment, the engaging portion 52 is provided at the upper end and the auxiliary engaging portion 55 is provided at the lower end. However, the present invention is not limited to this, and the support hole 53 through which the lock pin 14 is inserted is the main body portion 51. In the case of being provided at the upper portion, the engaging portion 52 may be provided at the lower end and the auxiliary engaging portion 55 may be provided at the upper end.

  Furthermore, in the said embodiment and Example, although the triangular-shaped lock claw 141 was demonstrated, it is not limited to this, It is attached to the side surface of the lock pin 14, and it is between an axial direction and an axial orthogonal direction. A well-known lock mechanism or prevention structure such as a rotary lock mechanism or an insertion-type retaining pin capable of stopping the pivotable pin in the direction perpendicular to the axis can be applied.

  In the above embodiment, the handrails 2A and 2B and the baseboards 3A and 3B are attached as the cross members by the handrail baseboard and metal fittings 4. Can also be attached.
