ある。Scaffolding boards (fabric frames) that are used by straddling between scaffolding frames at construction sites, etc. are made of steel plates that have been processed and formed so that they do not slip on the walking side surface, and gripping metal fittings are provided at both side ends,
It is a structure that can be locked to a round frame (frame support) provided horizontally. When the scaffold plate is installed horizontally on a horizontal round frame, the grips are locked by the fitting recesses of the grips that face downward, but if they are left as they are, they will be blown away by strong cross winds. If the scaffolding plate is locked to the round frame, the engagement cam will naturally attach to the grip even if a light shock occurs when the scaffolding plate is locked to the round frame. Is configured so that the lower end of the engagement cam projects into the fitting recess, holds the round frame, and does not fly even if a force from below is applied. When the scaffolding plate is to be removed from the round frame, the operator lifts the lower end of the engagement cam of the gripping metal with a hand from under the scaffolding plate, and raises the engagement cam as it is. While holding it, he lifted the scaffolding board up and removed it from the round frame. Further, the shape of the gripping metal is such that a locking projection made of a rivet or the like is provided on the base of a semicircular fitting recess that fits in a round frame,
This is movably locked by a locking hole of the engaging cam. There are usually two holes on the upper and lower sides of the engaging cam. The upper hole is the locking hole, and the lower hole is the direction of the lower end of the engaging cam so that the lower end of the engaging cam projects to grasp the round frame. It is a guide hole that indicates.

全なつかみ金具を得ることを目的とする。However, with conventional grips, when removing from the scaffolding board,
If the operator does not continue to lift the cam of the gripping tool from under the scaffolding plate, the engaging cam will drop naturally and the fitting recess will be closed at the lower end of it, and the gripping tool cannot be removed from the round frame. There was a point. Therefore, if the length of the scaffolding board is normal, the gripping metal fittings at both ends of the scaffolding board cannot be pressed down, and if one operator wants to remove it, the engagement of the gripping metal fittings on one end side of the scaffolding board While lifting the compound cam, separate the gripping bracket from the horizontal round frame,
It had to be lifted without dropping it down to the other end of the scaffolding board, and the work of removing the grips on that side had to be done, which was extremely difficult and difficult work.
Therefore, normally, there is a problem that the scaffolding board must be removed by at least two workers who have persons at both ends of the scaffolding board. In addition, when the engaging cam is raised, the rivet, which is a locking rod, is reliably caught too far when the engaging cam is raised to open the fitting recess of the gripping metal. ,
There was a problem that the engagement cam did not fall down just after the shock. Therefore, if the scaffolding board is used in such a state, there is a high possibility that an accident may occur in which the scaffolding board is blown by being blown by the force of strong wind or the like, which is highly dangerous. In this device, the scaffolding plate can be easily removed from the horizontal round frame of the scaffolding frame by one person's work, and when the scaffolding plate is engaged with the horizontal round frame, the engaging cam surely falls down even with a light shock. An object of the present invention is to obtain a safe gripping metal fitting that securely grips a round frame by projecting the lower end portion into the fitting recess.

して形成した。In order to achieve this object, the present invention provides a holding metal fitting of a scaffolding plate, an engaging cam of which is projectable in a fitting recess of the holding metal fitting, and the engaging cam is movably locked to a locking projection. It has a locking hole that is a dogleg-shaped elongated hole that curves in a direction opposite to the semicircular bending direction of the fitting recess, and a guide hole that is slightly curved in a direction opposite to the dogleg shape of the locking hole. The shape of the locking hole is such that the lower end of the engagement cam locks in the locked state where it protrudes into the fitting recess, and the upper end of the engagement cam protrudes into the fitting recess when it is unlocked. An unlocking locking end that stops and a temporary locking part that locks in a temporary locking state in which the engagement cam does not project into the fitting recess are formed on the convex portion of the dogleg shape in the inward bending direction, and It was formed as a locking hole of an engaging cam having a concave portion adjacent to the locking portion.

The engagement cam has a locking hole for locking the locking projection. When the scaffold plate is engaged with the round frame, the holding metal of the scaffold plate locks the engagement cam with the locking projection at the lock locking portion at the upper end. At this time, the lower end portion of the engagement cam projects into the fitting concave portion and is in a locked state. When the scaffolding plate is to be removed from the round frame, it is locked to the locking projection by the temporary locking locking portion formed in the middle of the locking hole. At this time, neither the lower end nor the upper end of the engagement cam protrudes into the fitting recess. Therefore, in this state, the scaffolding plate engages with the round frame at the fitting recess of the gripping metal, while the engaging cam does not grasp the round frame at the lower end, so lift the scaffolding plate from below and remove it. You can Furthermore, when trying to engage the scaffolding plate with a horizontal round frame,
The locking hole of the engaging cam is locked to the locking projection at the unlock locking portion at the lower end. In this state, the upper end of the engagement cam projects above the fitting recess, and when the fitting recess engages the round frame, the protruding portion of the engagement cam is naturally pushed down and falls due to gravity. The lower end of the is projected into a locked state.

The holding metal fitting body 2 is made of a plate-shaped body such as a steel plate, and is made up of a connecting portion 20 connected to the main body of the scaffolding plate 5 and a fitting recess 21 that engages with the round frame 6 when it is bridged. . The fitting recess 21 has a shape in which the semicircular recess faces downward and the top of the recess faces upward when the scaffold plate is placed horizontally. In the middle part between the fitting recess 21 of the grip body 2 and the connection part 20,
A locking projection hole 22 and a conductive projection hole 23 are vertically formed so as to be adjacent to the fitting recess 21. The locking projection member 4 is a locking projection that fits into the locking projection hole 22.
40 and a guide projection 41 fitted in the guide projection hole 23. In this embodiment, the locking projection 40 and the guide projection 41 are formed by rivets, respectively, and the ends of the grip fitting body 2 are caulked and fixed. . The engagement cam 3 is a small piece formed of a plate-shaped body such as a steel plate, and has a crescent-shaped front shape with a slightly rounded front end, and the curved direction is a semicircular curvature of the fitting recess. Same as direction. When the engaging hole 3 and the guide hole 31 are formed in the engaging cam 3 and the engaging cam 3 is attached to the grip metal body 2 and the scaffolding plate 5 is placed horizontally, the engaging hole 30 is located above. The position. The locking hole 30 is a V-shaped long hole having a bent portion in the middle, and the bending direction is a semicircular shape of the fitting recess when the engagement cam 3 is attached to the grip body 2. It is the opposite direction to the curving direction. The bent portion is bent at a position slightly deviated to one side in the length direction of the locking hole 30, and the bending angle is about 30 °. This bent portion grips the engagement cam 3 and attaches it to the metal fitting body 2,
When the scaffolding plate 5 is placed horizontally on the round frame 6 etc., the locking holes 30
The position is slightly lower than the middle of. The locking hole 30
The upper end of the long hole is a semi-circular lock locking end 300, and the lower end of the long hole is a semi-circular unlock locking end 301,
An inner protruding portion in the bending direction of the bent portion is configured as the temporary locking portion 302. A concave portion 303 is formed slightly above the temporary locking portion 302 side of the locking hole 30 to make the projection angle of the temporary locking portion 302 slightly acute. The locking hole 30 is movably locked to a locking projection 40 that is fixed by crimping the end portion to the locking projection hole 22 of the grip body 2. In this embodiment, the thickness of the rivet of the locking projection 40 is about
6 mm, the width of the locking hole 30 is about 7 mm. Also, the locking hole 30

Up to 01 is about 10 mm. The guide hole 31 is slightly curved in the opposite direction to the locking hole 30. This curve has a shape in which the upper end portion and the lower end portion are bent with a short straight line portion in between. The guide hole 31 is movably locked to a guide projection 41 (about 6 mm in thickness) fixed by crimping the end to the guide projection hole 23 of the grip body 2. In this embodiment, the guide hole 31 has a width of about 7 mm and a length of about 2 mm.
It is 1 mm. Next, the operation of this invention will be described. When the scaffolding plate 5 is bridged over the horizontal round frame 6 or the like, the fitting recess 21 of the grip 1 is placed on the round frame 6 while engaging. When attempting to place this, that is, before engaging, it is in an unlocked state so that the lower end of the engagement cam 3 does not project into the fitting recess 21 (Fig. 3). In this unlocked state, the locking projection 40 is locked by the unlocking locking end portion 302 of the locking hole 30.
Is locked to. In the unlocked state, the upper end of the engagement cam 3 projects to the top of the fitting recess 21. At this time, since the locking hole 30 is locked to the locking protrusion 40 in a state of being slightly horizontal, it cannot be easily disengaged. Then, in this state, when the fitting recess 21 of the grip 1 is engaged with the round frame 6, the upper part of the round frame 6 is brought into contact with the upper end portion of the engaging cam 3 protruding to the top of the recess of the fitting recess 21. Since they collide with each other, the engagement cam 3 is impacted by the impact force, and the engagement protrusion 40 and the engagement hole 30
The unlocking lock end 302 of the lock is released, the engagement cam 3 naturally falls due to gravity, and the lock protrusion 40 locks to the lock lock end 300 at the upper end of the lock hole 30. , It will be locked. At this time, the engagement cam 3 is also engaged with the guide protrusion 41 together with the engagement protrusion 40, and the lower end portion of the engagement cam 3 is fitted according to the shape of the guide hole 31 also engaged with the guide protrusion 41. It projects below the fitting recess 21 as shown in FIG. Also, when trying to remove the scaffolding plate 5 from the horizontal round frame 6,

At this time, since it is included in the concave portion 303, it can be locked easily. In this state, neither the lower end nor the upper end of the engagement cam 3 protrudes into the fitting recess 21. Therefore, the scaffolding plate 5 is placed on the round frame 6 in the fitting recess 21 of the holding metal fitting 1, but the lower end of the engagement cam 3 does not grip the round frame 6, so that the scaffolding plate 5 is placed below the scaffolding plate 5. Can be lifted from and removed. In this state, the scaffolding plate 5 is put in this state and immediately lifted upward to remove it, so in consideration of the risk of forgetting in this state, it is easy to fall into the locked state immediately with a small impact. The lock will be released. The concave portion 303 has an effect that the engagement cam 3 can be easily dropped from the unlocked state to the locked state, and can be easily caught when the locked state is changed to the temporary locked state.
