Description

The present disclosure relates to a wedge binding scaffolding clamp used in constructing a wedge binding scaffold.

For example, at various building construction sites, civil engineering sites, etc., temporary scaffolding is constructed for workers, and then various operations are carried out. When constructing a temporary scaffold, for example, scaffold constituent members such as posts, cloth materials, cloth frames, and preceding handrail braces are used, and the cloth materials and the like are connected to the posts. As this connection structure, for example, a structure using a wedge fixed to the end of a cloth material so as to protrude downward and a pocket fixed to the outer peripheral surface of the support is known (for example, Patent Documents 1 to 3).

Patent Literature 1 discloses a clamp in which first and second clamping members that sandwich a column in the radial direction are rotatably connected. Each clamping member has a horizontal plate portion and a vertical plate portion. The horizontal plate portion has wedge insertion openings formed at intervals of 90 degrees, and the vertical plate portion has a wedge inserted into the wedge insertion opening. A convex portion is formed in contact with the side surface of the .

Further, the clamp disclosed in Patent Document 2 includes an upper plate portion and a lower plate portion, and cutout portions into which wedges are inserted are formed in the upper plate portion and the lower plate portion. Further, in this clamp, the upper plate portion and the lower plate portion are provided so that the inclined plate portion formed by the support is inclined along the side surface of the wedge.

Further, the clamp disclosed in Patent Document 3 forms a pocket into which a wedge can be inserted by bending a vertically extending plate.

By the way, in general, the wedge has a lower end that is thinner than its upper end in consideration of ease of insertion into the wedge insertion port. is inclined in a direction approaching the outer surface of the column as much as possible. On the other hand, in the clamp of Patent Document 1, the portion facing the side surface of the wedge is a vertical plate portion, and this vertical plate portion is parallel to the outer surface of the column. That is, the sides of the wedge and the vertical plate portion do not extend in the same direction. In Patent Literature 1, since the convex portion formed on the vertical plate portion contacts the side surface of the wedge, the vertical plate portion and the side surface of the wedge are in point contact, and the contact area is extremely narrow. Therefore, there is a possibility that the fixing strength of the wedge may be lowered.

Therefore, as in Patent Document 2, it is conceivable to provide an inclined plate portion inclined along the side surface of the wedge. However, since the inclined plate portion is made of a separate member from the upper plate portion and the lower plate portion, the number of parts increases and a welding process is required to weld the inclined plate portion to the upper plate portion and the lower plate portion. and the number of man-hours for manufacturing also increases.

In this regard, in the clamp of Patent Document 3, since the pocket is formed by a single vertically extending plate material, it is considered that the number of parts and manufacturing man-hours can be reduced compared to Patent Document 2. However, since the portion in contact with the support is also made of a plate material extending in the vertical direction, the contact area with the outer peripheral surface of the support increases, and as a result, there is a risk that the surface pressure will decrease.

The present disclosure is made in view of this point, and its purpose is to increase both the fixing strength of the wedge to the clamp and the fixing strength of the clamp to the support while reducing the number of parts and manufacturing man-hours. be.

In order to achieve the above object, in one aspect of the present disclosure, a wedge binding used in a wedge binding type scaffold constructed by inserting a wedge of a scaffolding component from above into a pocket provided on a post and fixing it A scaffolding clamp can be assumed. In the wedge binding scaffolding clamp, a first holding member and a second holding member that hold the support in a radial direction, and one end side of the first holding member and one end side of the second holding member are brought into contact with each other. a connecting member that connects the other end side of the first holding member and the other end side of the second holding member so as to be rotatable in a direction; one end side of the first holding member and one end side of the second holding member; and a fastening member that fastens them in a direction toward each other. The first holding member includes a first upper plate portion and a first lower plate portion that extend in the radial direction and are arranged with a space therebetween in the vertical direction, and abut on the outer peripheral surface of the support from one side in the radial direction. and a first vertical plate portion continuous from the radially outer end portion of the first upper plate portion to the radially outer end portion of the first lower plate portion, wherein the first upper plate portion, the second The first lower plate portion and the first vertical plate portion are integrally molded from one plate material. Further, the second holding member extends in the radial direction and is arranged with a space therebetween in the vertical direction, and a second upper plate portion and a second lower plate contact the outer peripheral surface of the support from the other side in the radial direction. and a second vertical plate portion continuous from the radially outer end portion of the second upper plate portion to the radially outer end portion of the second lower plate portion, the second upper plate portion; The second lower plate portion and the second vertical plate portion are integrally molded from one plate material. A plurality of the first upper plate portions are provided at intervals in the circumferential direction of the column, and a plurality of the first lower plate portions are provided at intervals in the circumferential direction of the column. A first pocket is formed between the first upper plate portions adjacent in the circumferential direction and between the first lower plate portions adjacent in the circumferential direction. A portion corresponding to the pocket has a flat plate shape that slopes along the side of the wedge opposite to the support and is in surface contact with the side .

According to this configuration, the first upper plate portion, the first lower plate portion, and the first vertical plate portion, which constitute the first clamping member, are integrally molded from a single plate material, and constitute the second clamping member. Since the second upper plate portion, the second lower plate portion, and the second vertical plate portion are integrally molded from one plate material, the number of parts is reduced, the welding process is unnecessary, and the manufacturing man-hours are reduced. is also reduced.

Further, when the first holding member and the second holding member are rotated in a direction in which the one end side of the first holding member and the one end side of the second holding member are separated from each other, the one end side of the first holding member and the second holding member are rotated. Since the distance from the one end side of is widened, it becomes possible to dispose the post between the first holding member and the second holding member. After arranging the post between the first holding member and the second holding member, the first holding member and the second holding member are arranged in a direction in which one end side of the first holding member and one end side of the second holding member approach each other. is rotated, the first upper plate portion and the first lower plate portion of the first clamping member and the second upper plate portion and the second lower plate portion of the second clamping member respectively move against the outer peripheral surface of the support column. They are in contact with each other from one side and the other side in the radial direction of the strut. The clamp is fixed to the post by fastening the one end side of the first clamping member and the one end side of the second clamping member with the fastening member so as to approach each other.

Since the first upper plate portion, the first lower plate portion, the second upper plate portion, and the second lower plate portion each extend in the radial direction of the support when fixed to the support, the contact area with respect to the support is reduced. , the surface pressure increases. Thereby, the first upper plate portion, the first lower plate portion, the second upper plate portion, and the second lower plate portion are firmly fixed to the column.

Here, in general wedges, the lower end is narrower than the upper end when the tip of the wedge in the insertion direction is the lower end. It is slanted in a direction approaching the outer surface.

When a wedge having the above shape is inserted into the first pocket of the clamp, the portion of the first vertical plate portion corresponding to the first pocket is inclined in the same direction along the side surface of the wedge, so that the wedge and the first vertical plate portion come into surface contact with each other, and the contact area between the two is widened. Therefore, the fixation strength of the wedge is increased.

In another aspect of the present disclosure, second pockets may be formed between the second upper plate portions adjacent in the circumferential direction and between the second lower plate portions adjacent in the circumferential direction. In this case, the portion of the second vertical plate portion corresponding to the second pocket may be formed to be inclined along the side surface of the wedge opposite to the support. As a result, the wedge inserted into the second pocket can also be firmly fixed. A third pocket and a fourth pocket may be provided.

Further, the width of the radially outer end portion of the first upper plate portion may be set wider than the width of the radially inner end portion of the first upper plate portion. In other words, the width of the radially inner end portion of the first upper plate portion can be made narrower than the width of the radially outer end portion of the first upper plate portion. It becomes even smaller, and the surface pressure can be further increased.

Further, the first vertical plate portion may be inclined at the same angle as the portion corresponding to the first pocket, except for the portion corresponding to the first pocket. As a result, the entire first vertical plate portion has a shape inclined at the same angle, which facilitates molding and improves moldability.

Further, the height of one of the first upper plate portion located at the end portion in the circumferential direction of the first holding member and the second upper plate portion located at the end portion in the circumferential direction of the second holding member can be set to be positioned below the other. As a result, at least a portion of the first upper plate portion overlaps the second upper plate portion in the thickness direction, thereby suppressing vertical displacement between the first holding member and the second holding member.

Further, the height of one of the first lower plate portion positioned at the end portion in the circumferential direction of the first holding member and the second lower plate portion positioned at the end portion in the circumferential direction of the second holding member may be set to be positioned below the other. As a result, at least a portion of the first lower plate portion overlaps the second lower plate portion in the thickness direction, so that the effect of suppressing vertical displacement between the first holding member and the second holding member is enhanced. Get even higher.

Moreover, the mutually facing edge portions of the first upper plate portions that are adjacent in the circumferential direction may constitute both width direction edge portions of the first pocket. According to this configuration, when the wedge is inserted into the first pocket from above, both sides of the wedge in the width direction come into contact with the edges of the first upper plate, so that the wedge can be positioned at a predetermined position.

As described above, the first upper plate portion, the first lower plate portion, and the first vertical plate portion of the first clamping member are integrally molded from one plate material, and the second upper plate portion, the first vertical plate portion, and the second clamping member of the second clamping member. Since the second lower plate portion and the second vertical plate portion are integrally molded from one plate material, the number of parts and manufacturing man-hours can be reduced. Further, since the first upper plate portion, the first lower plate portion, the second upper plate portion, and the second lower plate portion extend in the radial direction, the fixing strength of the clamp to the column can be increased. Furthermore, since the portion of the first vertical plate portion corresponding to the pocket is inclined along the side surface of the wedge, the fixing strength of the wedge to the clamp can be increased.
