[Detailed description of the invention]

[0001]

[Industrial application field] The present invention is intended for use in assembling temporary scaffolds and the like at a construction site.
The present invention relates to a fastening device suitable for fastening a horizontal member such as a beam receiving beam and the like, and relates to a Japanese Utility Model Application No.
64539 relates to an improvement.

2. Description of the Related Art A fastening device disclosed in Japanese Utility Model Laid-Open Publication No. Hei 1-64539 is provided with two ends of a horizontal member at a peripheral portion of a fitting body provided with a through hole for a pillar such as a temporary scaffold at the center. Four supporting arms are protruded at appropriate intervals, and a center portion of each arm is formed so as to provide a fastening hole for fastening both ends of the horizontal member with a lock and a wedge.
In use, a temporary scaffold or the like is pierced through a penetration hole of the tie fitting and fixed at appropriate intervals along the longitudinal direction by a welding means or the like, and the temporary scaffold or the like is assembled at a building site. At this time, erection columns with the tie ties fixed at appropriate intervals along the longitudinal direction are erected at appropriate intervals along the outer wall surface of the building at the construction site, and horizontally at the same height of each of these columns. Both ends of the horizontal member are supported between the arms of the opposing fastening members via lock fittings, and wedges are inserted into the fastening holes of each arm and the locking fittings so as to be fastened to each other.

[0003]

[Problems to be Solved by the Invention] However, when assembling a temporary scaffold or the like at a construction site, since the thickness of each arm of the bracket main body is thin, rattling occurs between the arm of the bracket main body and the lock bracket. There is a possibility that the wedge may be loosened even by the vibration, and the state where the horizontal member is tightly connected to the arm of the bracket main body is unstable. In addition, when supporting the lock members at both ends of the horizontal member to the arm of the metal member main body, if the horizontal member is slightly inclined, it is difficult to guide the lock metal member to the arm of the metal member main body, and the arm and the lock metal member are not connected to each other. Rattling is likely to occur between the horizontal members, and the horizontal member cannot be stably connected to the arm of the bracket main body. Furthermore, since the metal fittings are integrally formed, there is a problem that the metal fittings are difficult to form, are not suitable for mass production, and are expensive.

Therefore, the present invention has been devised in order to solve the above-mentioned problem, and the wedge is not loosened by a slight vibration as in the prior art, and the horizontal member is stably attached to the arm of the bracket main body. Even if the horizontal member is slightly inclined, the horizontal member can be stably connected to the arm of the bracket main body without rattling. Furthermore, the formation of the bracket main body is simplified, and mass production is possible and inexpensive. It is intended to provide a tying member for a horizontal member such as a temporary scaffold.

In order to achieve the above-mentioned object, a metal member having a central portion provided with a through-hole for a column such as a temporary scaffold is provided at a peripheral portion of a metal member for supporting both ends of a horizontal member. of
One or a plurality of arms are protruded, and a thick binding portion bulging in the vertical direction is provided at a base end side of the arm, and a proximal end of the binding portion is provided at a distal end of the binding portion. A guide portion for guiding both ends of the horizontal member which is gradually inclined toward the tip from the upper and lower surfaces of the portion is provided, and a portion extending from a part of the binding portion to the tip of the guide portion is provided with both ends of the horizontal member. A lock hole and a binding hole for binding with a wedge are provided, and the metal fitting body is composed of an upper binding plate and a lower binding plate, and the upper binding plate and the lower binding plate formed separately are connected to each other. It is formed so as to be superposed and joined by projection welding or the like.

The metal fitting body is composed of an upper binding plate and a lower binding plate, and the upper binding plate and the lower binding plate formed separately are overlapped and joined by projection welding or the like. May be formed.

[0007]

With the above-mentioned technical means, in use, the lock fittings at both ends of the horizontal member are supported by the binding portion of the arm of the fitting body during use, and wedges are inserted into the binding holes of the binding portion and the lock fitting. When the arm is tied together, rattling between the arm tying portion and the lock fitting can be prevented. Also, when supporting the lock fittings at both ends of the horizontal member at the binding part of the arm of the fitting body, even if the horizontal member is slightly inclined, the locking fitting is guided by the binding part of the arm of the fitting body, and the guide part is easily guided. Be supportive.

[0015]

According to the present invention, one or more supporting members for supporting both ends of a horizontal member are provided at the peripheral portion of a metal fitting body having a through hole for a pillar such as a temporary scaffold at the center as described above. An arm is protruded, and a thick binding portion bulging in the vertical direction is provided on the base end side of the arm, and the distal end of the binding portion is provided with a distal end from the upper and lower surfaces of the proximal end of the binding portion. A guide portion for guiding both ends of the horizontal member which is gradually thinned toward is provided, and at a portion extending from a part of the binding portion to the tip of the guide portion, both ends of the horizontal member are locked with a metal fitting and a wedge. It is configured to provide a tightening hole for tightening, and in particular, a horizontal member is formed at the base of the arm of the metal fitting main body by swelling up and down in the vertical direction to increase the wall thickness. Support the lock fittings at both ends, insert wedges into the fastening holes of the binding part and the lock fittings. When tied, it is possible to prevent rattling between the joint of the arm and the lock fitting, so that the wedge does not loosen due to some vibration as in the past, and the horizontal member is stably attached to the arm of the fitting main body. You can be tied to.

Moreover, the guide member is gradually inclined from the upper and lower surfaces of the base portion of the fitting portion toward the distal end at the distal end portion of the binding portion of the fitting body, so that the horizontal member is provided at the binding portion of the arm of the fitting body. When supporting the lock fittings at both ends, even if the horizontal member is slightly inclined, the lock fitting can be easily supported at the binding portion of the arm of the fitting main body with the guide part as a guide. Even if it is inclined, the horizontal member can be stably connected to the arm of the bracket main body without rattling.

Further, by providing a binding hole at a portion extending from a part of the binding portion of the metal fitting body to the distal end of the guide portion, when the wedge is inserted into the binding hole of the arm, the wedge is moved from the proximal end to the distal end. Because of the progressively thinner as we go to the side,
The wedge is supported at three points, the upper and lower two points on the binding part side of the binding hole and the one point on the guide part side, so that wedge rattling can be prevented, wedges do not loosen with slight vibration, The horizontal member can be more stably tied.

Further, the metal fitting body is composed of an upper binding plate and a lower binding plate. The upper binding plate and the lower binding plate formed separately are overlapped and joined by projection welding or the like. With such a configuration, the metal fitting body can be easily formed, can be mass-produced, and can be provided at low cost.
