Description

  In the present invention, in a building frame scaffolding in which cloth plates are arranged in parallel between the horizontal members on the upper edge of the building frame standing up at a predetermined interval, the cloth plates adjacent in the width direction move away from each other. The present invention relates to a metal plate stopper for a building scaffold to prevent.

  2. Description of the Related Art In general, a building frame scaffold is widely used in which a gate-shaped building frame is faced up in parallel and a pair of cloth boards are arranged in parallel between the horizontal members on the upper edge of the building frame. The cloth board used for this building frame scaffold has a rectangular shape as a whole, and hook metal fittings project from the four corners in the length direction. The hook fitting is formed with a concave portion in which the horizontal member of the building frame fits on the lower side, and the cloth board is stretched by fitting the horizontal member of the building frame into the concave portion of the hook fitting.

  In this way, if the cloth plates that are adjacent to each other in the width direction spanned across the building frame are displaced to the side away from each other, the material or equipment may be dropped from the gap or the operator may be caught in the gap. There is a risk of serious accidents.

  For this reason, conventionally, in order to prevent the cloth plates adjacent in the width direction from separating, a method of binding adjacent cloth plate hook metal fittings with a number wire has been used for a long time.

  However, the fixing work using the number wires must be performed manually, which takes time and increases the cost and the construction period. In addition, once used, the wire must be disposed of, which places a burden on the environment. Furthermore, the binding allowance easily jumps out to the upper and lower parts of the cloth board, and there is a possibility that clothes or the like may be caught on it or the operator's body may be damaged.

In order to solve such a problem, leg portions for preventing spread between adjacent hook fittings are provided on the lower surface of the plate covering the upper side of the hook fitting portion engaged with the horizontal member of the building frame. A cloth board slip prevention tool has been developed (for example, Patent Document 1).
Japanese Patent No. 4068632

  The above-mentioned conventional cloth plate displacement prevention bracket has four cloth plates hanging on one horizontal member, that is, a total of four cloth plates arranged in the width direction on both sides of one horizontal member. There is a problem that it cannot be used in a building frame scaffolding that is fixed at the same time and only two cloth plates are spanned between a pair of building frames.

  In addition, since the plate covers the top of the hook metal fitting, the upper surface of the scaffold is raised accordingly, it is easy to trip when walking, there is a problem with safety, and the shape is large and inconvenient to carry when attaching and detaching Furthermore, coupled with the fact that the locking mechanism is complicated, there has been a problem that the manufacturing cost has to be high.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional problems, and is intended to provide a cloth plate stopper for a building frame scaffold that can be used for a wider range of members at a lower cost and can be easily attached and detached. .

  In order to solve the conventional problems as described above and achieve the intended purpose, the feature of the device according to claim 1 is that two cloth boards having a rectangular shape having hook metal fittings protruding at four corners are provided. The displacement of the building frame scaffolding prevents the displacement of the both fabric boards of the building frame scaffolding configured by engaging the hook metal fittings with the horizontal members on the upper edge of the building frame and supporting them in parallel with each other. A fastener, which is formed entirely of an elastic metal linear material, and integrally includes a straight horizontal portion and a pair of legs bent at both ends thereof, the both legs being The lower end side is inclined toward the side closer to each other, and the outer sides of the hook metal fittings are elastically formed by the both leg portions with the horizontal portion straddling the upper surfaces of the hook metal fittings adjacent to each other of the two cloth boards. It is in the cloth board slip prevention metal fitting of the building frame scaffold comprised so that it may pinch | interpose.

  The feature of the invention described in claim 2 is that, in addition to the structure of claim 1, the tip of the linear material constituting the legs is folded upward and inward on the opposite surface side of the lower ends of the both legs. The ring-shaped locking projection is integrally formed, the leg portion is in a state where the horizontal portion is in contact with the upper surface of the hook metal fitting, and the lateral protruding top of the locking projection is the lower edge of the hook metal fitting. There is a length to the bottom.

  In the present invention, the entire cloth plate displacement prevention metal fitting is formed of an elastic metal linear material, and has a straight horizontal portion and a pair of leg portions bent at both ends downward, and the both legs. The lower end side is inclined toward the side closer to each other, and the horizontal portion is straddled on the upper surface of the hook metal fittings adjacent to each other on the two cloth boards, and the both leg metal parts The outer side is elastically pinched, so the shape is very simple, easy to manufacture, convenient to carry when attaching and detaching, and the hook metal fittings can be clamped by both legs. It can be easily removed by pulling out from the upper side, and in the mounted state, the outer side of the hook metal fitting is sandwiched by both legs, so it does not fall off easily, and the thickness of the linear material is the hook. Money Since only projects to the upper surface, nor dangerous to walk.

  In the present invention, on the opposite surface side of the lower ends of both legs, a ring-shaped locking projection formed integrally by folding the tip of the linear material constituting the legs upward inwardly, By setting the leg portion to a length in which the laterally projecting top portion of the locking convex portion extends below the lower edge of the hook metal fitting while the horizontal portion is in contact with the upper surface of the hook metal fitting, The resistance force when external force in the direction of disengagement is large, the anti-separation effect in the mounted state can be increased, and the tip of the linear material constituting both legs is rounded to the inside of both legs Since it does not protrude to the outside, safety for workers is high. Furthermore, during the mounting operation, the inside of the tip end portions of both leg portions has a circular curve, which makes it easy to insert the hook metal fitting.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 shows an example of a cloth plate misalignment fitting according to the present invention. The cloth plate misalignment fixture A is formed by cutting and bending a steel elastic linear material as a whole, and includes a straight horizontal portion 1 and a pair of leg portions 2 having both ends bent downward. , 2 and the whole is formed in a downward U-shape.

  Both leg portions 2 and 2 are inclined in the direction in which the tip ends approach each other, and at the lower end thereof, the tip of a linear material is bent into a shape of a substantially circular ring on the opposite side of the legs, that is, inside. The locking projections 3 and 3 are integrally formed. The front end of the linear material constituting the locking projection 3 is a linear portion 4 along the leg 2.

  As shown in FIGS. 2 and 3, the cloth plate misalignment fitting A is assembled by engaging the hook fittings 11, 11 of the cloth plates 10, 10 adjacent in the width direction with the horizontal member 12 of the building frame. It attaches to the base part of the hook metal fittings 11 and 11 of the mutually adjacent position of both the cloth boards 10 and 10 with respect to a building frame scaffold, and as shown in FIG. The distance L1 between the two bases is formed to be longer than the full width L2 of the hook metal fittings 11 and 11 in the close arrangement described above.

  Further, the lengths of both the leg portions 2 and 2 are formed such that the entire engaging projections 3 are positioned below the lower edge of the hook metal fitting 11. In addition, the length which the horizontal direction protrusion top part 3a of the engagement convex part 3 becomes below the lower edge of the hook metal fitting 11 should just be sufficient.

  The cloth plate misalignment metal fitting A configured as described above is attached by extending the ends of both leg portions 2 and 2 wider than the entire width of the hook metal fittings 11 and 11 and pressing them down on the outer side surfaces of the hook metal fittings 11 and 11. With the horizontal portion 1 straddling the hook metal parts 11, 11, the engaging convex parts 3, 3 are brought under the lower edge of the hook metal part 11. As a result, as shown in FIG. 3, the engaging projections 3 and 3 move in the direction approaching each other under the hook metal parts 11 and 11 due to the elasticity of the legs 2 and 2, and both hooks are held in a state where they are prevented from coming off. The metal fittings 11 and 11 are prevented from shifting in the separating direction.

  The cloth plate slip-off preventing metal fitting can be easily removed by pulling up the horizontal portion 1 using a tool such as a bar because the engaging convex portion is a ring shape having a substantially circular shape.

  In the above example, one horizontal member 10 of the building frame is supported by one end of each of the two cloth boards 10 from both sides, and four hook fittings 11 are provided at one place in the horizontal member length. In this case, the interval L1 between the leg bases is between the two hook metal fittings 11 and 11 on the approaching side of the cloth plates 10 and 10 adjacent to each other in the width direction. It is formed to be larger than the full width L2 in the state where the hook metal fitting 11 of the cloth board 10 on the opposite side of the building frame horizontal member is interposed.

  In addition, the distance L1 between the leg bases is such that the hook metal fittings on the opposite side of the horizontal member 12 are not sandwiched between the close hook metal fittings 11, 11 of the cloth boards 10, 10 adjacent in the width direction. In the erected building frame scaffolding, the length is made to correspond to the entire width of the two hook fittings 11 and 11 that are close to each other and are to be prevented from shifting.

It is a front view which shows an example of the cloth board slip prevention metal fitting which concerns on this invention. It is a top view which shows the use condition of the cloth board slip prevention metal fitting shown in FIG. It is a longitudinal cross-sectional view same as the above.
