  However, as shown in Patent Document 2, the number of pressing members is a plurality that is used alternately and exchanged, and the parapet is attached together with the second contact member provided in the first downward extending portion. When the pressing member to be clamped is used alternately and replaced, the position of the pressing portion by the pressing member is shifted before and after replacement, and the parapet is stable between the pressing member and the second contact member. In order to be able to pinch, it is required to be able to pinch the parapet stably with a load that is not offset.

  The object of the present invention is to use a pressing member and an abutment member to separate the standing wall-like material both before and after replacement, even if a plurality of pressing members that press the standing wall-like material such as a parapet are replaceably provided. It is to provide a stanchion that can be stably pinched with a load that is not shifted.

  The stanchion according to the present invention includes a cross section that crosses above a standing wall-like object of a structure in the thickness direction of the standing wall-like object, an upward extending part that has a length extending upward from the transverse part, and the crossing. A length extending downward from the first portion, and a length extending downward from the transverse portion, and a first downward extending portion facing one of the surfaces on both sides in the thickness direction of the standing wall-like object. A second downwardly extending portion facing the other of the surfaces on both sides in the thickness direction of the standing wall-like object, and the upper extending portion includes An attachment portion for attaching a handrail member having a length extending in the longitudinal direction is provided, and a first contact member that contacts the upper surface of the standing wall-like object is provided in the transverse portion, and the first downward extension is provided. A second abutting member that abuts against the one surface of the standing wall-like object is provided at the protruding portion. In a stanchion in which a pressing member that presses the other surface of the standing wall-like object is provided in the second downward extending portion, the thickness direction of the standing wall-like object from the second contact member as the pressing member One first pressing member that is disposed at a position apart from the second abutting member and whose longitudinal and vertical positions are the same as or substantially the same as the second contact member. And two second pressing members arranged at symmetrical positions around the first pressing member in a plane parallel to the other surface of the standing wall-like object, The one pressing member and the two second pressing members can be selectively advanced and retracted toward the standing wall-like object.

  In the stanchion according to the present invention, one first pressing member and two second pressing members can be selectively advanced and retracted toward the standing wall-like object. The other surface of the object can be pressed, and thus maintenance work such as painting work can be carried out also on the place pressed by the pressing member.

  The first pressing member is disposed at a position away from the second abutting member in the thickness direction of the standing wall-like object, and the longitudinal and vertical positions of the standing wall-like object are the second abutting positions. Since it is arranged at the same position or substantially the same position as the member, when the standing wall-like object is clamped by the first pressing member and the second contact member, the standing wall-like object is stabilized by a load that is not offset. And can be pinched. Further, two second pressing members are pressed against the other surface of the standing wall-like object next to the one first pressing member, and the standing wall-like object is formed by the second pressing member and the second contact member. When sandwiched, the two second pressing members are arranged in symmetrical positions around the first pressing member in a plane parallel to the other surface of the standing wall-like object. Even when the standing wall-like object is pinched by the second pressing member and the second contact member, the standing wall-like object can be stably pinched by a load that is not offset.

  In the present invention, as described above, in order to selectively advance and retract one first pressing member and two second pressing members toward the standing wall-like object, for example, the first pressing member is used. The two second pressing members are attached to the distal end portion of the rod-shaped member having a length extending from the second downwardly extending portion toward the standing wall-like object, and both ends of the intersecting member arranged perpendicularly to the rod-shaped member. The rod-like member may be attached to the portion, and the rod-like member may be advanced and retracted toward the standing wall-like object with respect to the second downwardly extending portion, and the cross member may be caused to advance and retreat with respect to the rod-like member toward the standing wall-like object.

  In addition, the first pressing member is attached to the tip end portion of the rod-shaped member having a length extending from the second downward extending portion toward the standing wall-like object, and the two second pressing members are perpendicular to the rod-shaped member. The rod-shaped member is attached to both ends of the intersecting member arranged in a crossing direction, and the rod-shaped member can be advanced and retracted toward the standing wall-shaped object with respect to the second downwardly extending portion. When it is possible to advance and retreat, the cross member may be rotatable around the rod-shaped member.

  According to this, by the rotation of the cross member around the rod-shaped member, the arrangement position of the two second pressing members with respect to the one first pressing member is changed in the left-right direction or the vertical direction, which is the longitudinal direction of the standing wall-like object. In addition, it is possible to arbitrarily set in the inclined direction inclined with respect to these directions, and the two second pressing members can be arranged at positions appropriately corresponding to the above-described maintenance work or the like.

  In order to allow the rod-like member to advance and retreat toward the standing wall-like object with respect to the second downwardly extending portion, for example, the rod-like member is a male screw rod, and the male screw rod is rotated with respect to the second downwardly extending portion. By doing so, the rod-shaped member may be moved back and forth toward the standing wall-shaped object with respect to the second downwardly extending portion. Further, in order to allow the cross member to move forward and backward with respect to the bar-like member, the cross member is provided with a through portion through which the male screw rod passes, and the through portion is moved along the male screw rod. Thus, the cross member may be moved forward and backward with respect to the rod-shaped member toward the standing wall-like object. Further, before and after the penetration part, the nut is screwed onto the male threaded rod, and after the penetration part is moved along the male threaded rod, the cross member is moved to the male threaded rod by tightening the penetration part with these nuts. It may be possible to fix it impossible.

  Further, as described above, two second pressing members are attached to both ends of the intersecting member that is arranged perpendicularly to the rod-shaped member, and the other surface of the standing wall can be pressed by these second pressing members. In order to do so, both end portions of the cross member may be bent portions bent toward the standing wall-like object, and two second pressing members may be attached to the tip portions of these bent portions.

  In the present invention described above, the upper extension part and the second lower extension part can be arranged in an arbitrary positional relationship in the length direction of the transverse part.

  As an example, the work target area where the work is performed by attaching the handrail member to the attachment portion provided in the upward extension portion is from the other surface of the standing wall-like object, In the case where the region is on the side opposite to the one surface side, the upper extension portion is disposed directly above or substantially above the second lower extension portion.

  According to this, the handrail member attached to the attachment portion of the upward extension portion is disposed at a position opposite to the one surface of the standing wall-like object with respect to the other surface of the standing wall-like object. Therefore, in a work area that is in front of the standing wall-like object, work such as maintenance work can be performed while ensuring safety.

  Further, in the case where the upper extension portion is arranged directly above or substantially above the second lower extension portion in this way, a fitting member is fitted to the outer periphery of the crossing portion, and the second member extends from the fitting member. (2) The lower extending portion may be extended downward, the upper extending portion may be extended upward from the fitting member, and the position of the fitting member in the transverse portion may be adjustable in the length direction of the transverse portion.

  According to this, the upper extension portion can always be arranged directly above or substantially directly above the second lower extension portion, and the position of the fitting member in the transverse portion is determined in the length direction of the transverse portion. By adjusting to, it becomes possible to cope with standing wall-like objects having different thickness dimensions.

  The stanchion according to the present invention described above can be applied to any standing wall-like object, and this standing wall-like object may be a parapet of a building, a beam of a building or a steel tower, a bridge, a bridge girder, or the like. Therefore, the structure in which the stanchion according to the present invention is used may be a building, a steel tower, a bridge, or the like.

  According to the present invention, even when a plurality of pressing members that press the standing wall-like object such as a parapet are replaceably provided, the standing wall-like object is offset by the pressing member and the contact member both before and after the replacement. It is possible to obtain an effect that the pinching can be stably performed with a load having no load.

  In FIG. 8, the first pressing member 31 is separated from the inner surface 2B of the parapet 2 by retreating the shaft portion 30B of the male screw rod 30 from the parapet 2 by the reverse rotation operation of the rotation operation portion 30A. The state in which the two second pressing members 33 are brought into contact with the inner surface 2B of the parapet 2 by advancing the crossing member 32 toward the parapet 2 along the shaft portion 30B of the male screw rod 30 is shown. .

  Also at this time, the first contact member 21 provided in the crossing portion 11 contacts the upper surface 2C of the parapet 2, and the second contact member 23 provided in the first downward extending portion 13 is It abuts against the outer surface 2A of the parapet 2.

  For this reason, the two second pressing members 33 are brought into contact with the inner surface 2B of the parapet 2 by advancing the crossing member 32 toward the parapet 2 along the shaft portion 30B of the male screw rod 30 as described above. When these second pressing members 33 press the inner surface 2B, the parapet 2 is sandwiched between the second abutting member 23 and the two second pressing members 33, and this is also the case. The stanchion 10 according to the form is fixed to the parapet 2.

  For this reason, in the present embodiment, one first pressing member 31 and two second pressing members 33 are alternately exchanged so that the inner surface 2B of the parapet 2 can be pressed. As shown in FIG. 1, a handrail member of a handrail pipe 3 is bridged over a stanchion 10 which is fixed to the parapet 2 at intervals, for example, an inner surface 2B of the parapet 2. As shown in FIG. 7, the first press member 31 presses the inner surface 2 </ b> B of the parapet 2, as shown in FIG. 7.

Since the nut is a wing nut 35 that allows the operator to advance the cross member 32 with a large pressing force, pressing the two second pressing members 33 against the inner surface 2B of the parapet 2 This can be done with a large pressing force.

  Particularly in the present embodiment, as described above, the arrangement position of the first pressing member 31 provided at the distal end portion of the shaft portion 30B of the male screw rod 30 is provided in the first downward extending portion 13. It is a position away from the second abutting member 23 in the thickness direction of the parapet 2, and the arrangement position of the first pressing member 31 in the longitudinal direction and the vertical direction of the parapet 2 is the same position as the second abutting member 23. Alternatively, since the positions are substantially the same, when the parapet 2 is clamped by the second abutting member 23 and one first pressing member 31, the parapet 2 can be stabilized with a load that is not offset. Can be pinched. Further, as described above, the two second pressing members 33 attached to both ends of the cross member 32 are centered on the first pressing member 31 in a plane parallel to the inner surface 2B of the parapet 2. Therefore, even when the parapet 2 is clamped by the second abutting member 23 and the two second pressing members 33, the parapet 2 is stably clamped with a load that is not offset. Can be pressed.

  Further, in the present embodiment, since the shaft portion 30B of the male screw rod 30 passes through the penetration portion 32A of the cross member 32, the cross member 32 can be rotated around the shaft portion 30B. The fact that the two second pressing members 33 press the inner surface 2B of the parapet 2 means that the two second pressing members 33 are moved in the longitudinal direction of the parapet 2 as shown by the solid line in FIG. It can be performed even if it is arranged in a certain left-right direction, and as shown by the two-dot chain line in FIG. 3, it can also be carried out by arranging the two second pressing members 33 ′ in the vertical direction. Since the two corresponding second pressing members 33 can be arranged by appropriately selecting corresponding positions, maintenance work can be easily performed.

  Further, the work area of the maintenance work performed using the stanchion 10 according to the present embodiment is opposite to the side of the outer surface 2A of the parapet 2 from the inner surface 2B of the parapet 2 shown in FIG. This area is the floor of the rooftop 1 that is the area in front of the parapet 2 and the inner surface 2B of the parapet 2.
