Description

  The present invention relates to a scaffolding plate for a temporary scaffold used in a temporary scaffold assembled at a construction site, for example, and more particularly to a scaffolding plate for a temporary scaffold that can be easily assembled.

  Conventionally, as disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2002-161635), Patent Document 2 (Japanese Patent Laid-Open No. 2015-140604), and the like, a temporary scaffold used at a construction site or the like is a horizontal round member on a column. Is constructed by building a scaffolding board on this horizontal round bar. This scaffold board is provided with latching hooks at both ends of the scaffold board body, and is latched by gripping the latching hooks from the upper side of the horizontal round member.

  The locking hook includes a hook portion for gripping the horizontal round member from the upper side and a locking piece attached to the hook portion so as to be able to advance and retract in order to prevent the scaffold plate from falling off. Then, after the hook part is gripped by the horizontal round member, the locking part is pulled out so that the hook part and the locking piece form an arc of 180 degrees or more, thereby preventing the locking hook from floating from the horizontal round member. Even when the scaffolding plate is pushed up from the lower side, the falling of the scaffolding plate is prevented.

  Similarly, Patent Document 3 (Japanese Patent Laid-Open No. 2008-8052) discloses a technique for preventing a locking hook from falling off, and includes a gripping portion having an opening that hooks a horizontal round member from above, and a part of the opening of the gripping portion. It has a retaining part that closes, and is configured to be able to switch between the locking hook and the horizontal round member by slidably configuring the retaining part to be detachable from the horizontal round member in the horizontal direction. Is disclosed.

  However, the scaffolding plates for the construction scaffold including the above-mentioned patent documents are configured so that the locking hooks provided on the scaffolding plate main body are locked from the upper side of the horizontal round member due to their structure. For this reason, when attaching the scaffolding plate to the horizontal round member, it is necessary to lift the scaffolding plate above the horizontal round member to be locked.

  This attachment work is usually performed on a scaffold board provided adjacent to the attachment position by an operator or on a scaffold board immediately below the attachment position. In this assembling work, the scaffolding board installation work on the adjacent scaffolding board is to attach the scaffolding board to the same height as the floor surface of the worker, so squatting on the neighboring scaffolding board. The work to move to the mounting position by holding one end of a long scaffolding board is a heavy burden on the operator, so it is substantially on the lower scaffolding board. In some cases, the work is carried out in a two-person posture with an auxiliary worker placed in the position, and the efficiency of the attachment work has deteriorated.

  On the other hand, the attachment work on the scaffold board immediately below the attachment position requires lifting the scaffold board to be attached once above the horizontal round member, and then attaching the locking hook to the horizontal round member. Since the distance between the horizontal round members at the mounting position is shorter than the distance between the hooks of the scaffolding plate, it is necessary to lift the scaffolding plate at an angle, and then hook the locking hook on the horizontal rounded material in a position that is difficult to see. . For this reason, there has been a problem that the burden of the attaching operation is heavy.

  Further, the removal of the scaffolding plate is required to be performed after pulling back the locking pieces provided at the four locations so that they can be removed. However, with the locking hooks of Patent Documents 1 and 2, Since the locking piece may move downward and move to the locking position due to vibrations, the removal work becomes complicated.

  Therefore, the technical problem to be solved by the present invention is to provide a scaffold plate for temporary scaffolding that can reduce the labor of assembly and removal work and facilitate these work.

  In order to solve the above technical problem, the present invention provides a scaffold plate for a temporary scaffold having the following configuration.

According to the second aspect of the present invention, the movable hook includes an upper hook that is gripped from an upper side of the horizontal round member and a locking piece that extends downward from the horizontal round member along the outer diameter of the horizontal round member. In a single shape,
The locking piece is configured such that, when the movable hook is in the retracted position, a tip end thereof is positioned outside the scaffold plate main body with respect to the upper hook. Provide scaffolding plates for temporary scaffolding.

According to a third aspect of the present invention, the movable hook includes a connecting leg having the rotation shaft provided at an intermediate position and pivotally attached to both side surfaces of the scaffold plate body,
The fixing mechanism provides a scaffolding plate for a temporary scaffold according to the first or second aspect, wherein the coupling leg and the scaffolding plate main body have fixing members that engage with each other.

  According to the fourth aspect of the present invention, the engaging member is disposed on the side surface of the scaffolding plate main body, and is disposed on the other end side of the connecting leg so as to be capable of moving forward and backward. A scaffolding plate for a temporary scaffold according to a third aspect is provided, which is composed of a fixing pin.

According to the fifth aspect of the present invention, the scaffold board main body is composed of a frame forming the outer shape of the scaffold board main body and a tread board member fixed to the upper surface of the frame.

  Hereinafter, a scaffold plate for a temporary scaffold according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a schematic configuration of a scaffold plate for a temporary scaffold according to the present invention. 2 is a perspective view from the back side of the temporary scaffolding scaffolding plate of FIG. FIG. 3 is an enlarged perspective view showing a state in which the scaffolding plate for temporary scaffolding in FIG. 1 is locked to the building frame for scaffolding. A temporary scaffolding scaffolding plate 1 shown in FIG. 1 (hereinafter sometimes abbreviated as a scaffolding plate) is a fixed hook as a locking plate provided at both ends of the scaffolding plate body 2 and the scaffolding plate body. 3. A movable hook 4 is provided, and the fixed hook 3 and the movable hook 4 are engaged with a horizontal round member 101 arranged opposite to the X direction of the scaffolding frame 100 to constitute a step board portion of the temporary scaffold. It is a member for.

  As shown in FIG. 3, the scaffolding frame 100 has struts 102 arranged in a lattice pattern at predetermined intervals in the longitudinal direction (X direction shown in the figure) and the short direction (Y direction shown in the figure). And a horizontal round member 101 is installed between columns adjacent in the X direction and the Y direction. In addition, as for the building frame 100 for scaffolds, the model, the connection structure of each part, etc. are arbitrary, and are not limited at all.

  As shown in FIG. 2, the scaffold board body 2 includes a frame 5 that forms the outer shape of the scaffold board 1, and a tread board member 6 that is provided along the upper surface of the frame. The frame 5 is formed by combining a U-shaped metal plate having a predetermined thickness into a rectangle to form a frame 5a, and has an intermediate member 5b extending in the X-axis direction at the center. The X-direction dimension of the scaffold board body 2 corresponds to the X-direction interval between the horizontal round members 101 determined to have a predetermined dimension, and is designed so that it is just fit between the horizontal round members 101. ing. On the other hand, the dimension of the scaffold plate body 2 in the Y direction may be configured such that a plurality of scaffold plates 1 can be arranged in the Y direction at intervals in the Y direction between horizontal round members.

  As shown in FIG. 4, the fixed hook 3 includes a hook portion 3 a and a connecting leg 3 b, and the scaffolding plate main body 2 is arranged such that the connecting leg 3 b is in a direction along the frame 5 of the scaffolding plate main body 2. It is fixed to one end of this with a fastening member (nut) 7. The fixed hook 3 is fixed to the inner surface of the frame 5 a of the frame 5.

  The hook portion 3a is configured to open downward so as to be gripped by the horizontal round member 101 from above, and includes an upper hook 8 that forms an arc upward from the connecting leg 3b, and an upper hook 8 that extends downward from the connecting leg 3b. And a locking piece 9 that forms a continuous arc.

  The upper hook 8 and the locking piece 9 continuously form an arc of about 180 degrees, and the radius is substantially the same as the outer radius of the horizontal round member 101. Further, the opening 10 of the hook portion 3a is opened obliquely downward and outward from the scaffold plate body 2 when viewed from the center of the arc. Therefore, as shown by the arrow 90 in FIG. 4, the horizontal round member 101 is held by the hook portion 3 a through the opening 10 from the lower outside of the scaffold plate 1. On the other hand, even after a force is applied to the horizontal round member 101 in a direction perpendicular to the horizontal round member 101, the anchor plate 9 prevents the scaffold plate 1 from falling off.

  As shown in FIG. 5, the movable hook 4 includes a hook portion 4a and a connecting leg 4b, and is fixed by a press-fitting member (rivet) 11a so that an intermediate position of the connecting leg 4b protrudes from an end of the frame 5. A pivotal support member (nut) 12 is pivotally attached to the attached mounting piece 11. The movable hook 4 is provided outside the side wall of the frame 5 and prevents interference with the fixed hook of the scaffolding plate continuously arranged in the X direction by making the mounting position of the fixed hook different from that of the Y direction. .

  The hook portion 4a has the same shape as the fixed hook, and includes an upper hook 13 that forms an arc upward from the connecting leg 4a, and a locking piece 14 that forms an arc continuous with the upper hook 13 downward from the connecting leg 4a. Provided, and an opening 15 is provided obliquely downward on the outside. Thereby, after the horizontal round member 101 is gripped, even if a force in a direction perpendicular to the horizontal round member 101 is applied to the scaffold plate 1, the locking piece 14 prevents the drop off.

  Therefore, after the horizontal round member 101 is gripped by the movable hook 4 and the fixed hook 3, the engagement by the hooks 3, 4 is configured not to be released unless it is lifted obliquely upward. That is, the scaffold board 1 of this embodiment attaches and detaches the scaffold board 1 from an oblique direction without attaching and detaching it from the direction perpendicular to the horizontal round material 101, that is, the vertical direction. And as above-mentioned, the movable hook 4 is comprised so that rotation is possible for the removal | desorption from the said diagonal direction.

  The movable hook 4 is rotatable around a rotation axis in the direction along the horizontal round member 101 around the rotation support member 12 used for pivotal attachment to the attachment piece 11. The movable hook 4 is movable between a locking position in which the connecting leg 4b shown in FIG. 5 faces the extending direction of the scaffold board body 2 and a retracted position in which the connecting leg 4b is substantially perpendicular to the scaffold board body 2. A zone. The state of the movable hook in the retracted position is shown in FIG.

  In the present embodiment, the movable hook 4 is configured such that the locking piece 14 extends below the horizontal position from the rotation support member 12 when in the locking position. With this configuration, the movable hook 4 is configured such that, in the retracted position, the locking piece 14 is positioned on the outer side of the scaffold plate body with respect to the rotating shaft and the upper hook 13.

  As shown in FIGS. 1 to 3, the movable hooks 4 are provided on both sides of the scaffolding plate body 2 in the Y direction. In order to rotate these hooks in conjunction with each other, a connecting member 4c is used to connect a pair of movable hooks. The connecting leg 4b is connected. The connecting member 4c is configured to be disposed on the back side of the scaffold board body 2 when the movable hook 4 is in the locking position (see FIG. 5).

  The connecting member 4c is provided with a fixing pin 17 as a fixing mechanism 16 for fixing to the scaffold board body 2. FIG. 7 is a partially enlarged perspective view schematically showing the configuration of the fixing mechanism when the movable hook of the temporary scaffolding scaffold plate is in the retracted position. FIG. 8 is a partially enlarged perspective view schematically showing the configuration of the fixing mechanism when the movable hook of the temporary scaffolding scaffold plate is in the locking position.

  The fixing pin 17 is supported so as to be able to advance and retreat by two receiving portions 18 arranged side by side on the facing surface 4d side of the tread body 2 of the connecting member 4c, and is urged by a spring member or the like to the frame side direction position. . The fixing pin 17 includes a fixing pin tip 17a protruding from the receiving portion 18 toward the frame 5 and a knob 17b formed by bending the rear end located at the center side of the frame 5 from the receiving portion 18 into an L shape. .

  When the fixed pin 17 is positioned above the lower wall 19 of the frame 5 a of the U-shaped frame 5 with the rotation of the movable hook 4, the fixed pin 17 is a recess defined by the lower wall 19 and the side wall 20 of the frame 5 a. The movable hook 4 is fixed at the locking position by engaging the tip 17a with the portion 21. As the movable pin 4 rotates from the retracted position to the locking position, the fixed pin 17 moves to the recessed portion 21 beyond the lower wall 19 of the frame 5a and retracts from the locking position. As a rotation suppression mechanism such as a ratchet that restricts the rotation of the movable hook 4 in the position direction, the tip 17a of the fixed pin 17 is formed on an inclined surface. Further, in order to release the fixing mechanism 16, the knob 17b of the fixing pin 17 may be pulled to move the tip 17a away from the frame 5a.

  Next, operation | movement of the scaffold board 1 concerning embodiment is demonstrated according to FIG. 9 thru | or FIG. The scaffold board 1 according to the present embodiment is operated by a worker on the floor surface immediately below the attachment position in order to obtain the attachment state shown in FIG. The worker lifts the scaffolding plate 1 so that the end on the fixed hook 3 side is upward, and locks the fixed hook 3 to the horizontal round member 101 from an oblique direction. As shown in FIG. 4 above, the hook portion 3a of the fixed hook 3 has an opening on the outside lower side and an opening 10 is provided at an oblique portion with respect to the center of the hook portion 3a. By moving the hook part 3 a to the horizontal round member 101 from the direction, the horizontal round member 101 can pass through the opening 10 and the hook part 3 a can grip the horizontal round member 101. For this reason, the opening 10 of the fixed hook is set to a position that allows the opening to pass through when the fixed hook 3 of the inclined scaffolding plate 1 is lowered in consideration of the inclination angle of the scaffolding plate 1 at the time of attachment. preferable.

  Next, in a state where the fixing mechanism 16 is released and the movable hook 4 is in the retracted position, the other end side (side on which the movable hook is provided) of the scaffold plate 1 is lifted. Since the fixed hook 3 is held by the horizontal round member 101 as described above, the other end side is lifted by rotating around the fixed hook 3 as a fulcrum. As shown in FIG. 9, when the movable hook 4 is in the retracted position, the tip of the locking piece 14 protrudes outward from the tip of the upper hook 13 of the hook portion 4 a and is in a position close to the horizontal round member 101. At this time, by constructing the scaffolding plate 1 so that the proximal end 101a of the horizontal round member 101 is positioned between the distal end of the locking piece 14 and the distal end of the upper hook 13, As shown in FIG. 10, the locking piece 14 contacts the horizontal round member 101.

  As shown in FIG. 10, when the scaffolding plate 1 is further lifted with the locking piece 14 in contact with the horizontal round member 1, the movable hook 4 rotates around the rotation support member 12 that is the rotation axis. In other words, the rotation support member 12 that is the rotation shaft is present at a position farther from the horizontal round member 101 side than the locking piece 14. Will move to the engagement position side. In addition, as described above, the hook portion 4a is opened at the lower outer side, and the opening 15 is provided at a portion obliquely below the center of the hook portion 4a, so that the upper hook 13 rotates obliquely from above. By moving, the horizontal round member 101 passes through the opening 15 and is held by the upper hook 13.

  Further, when the scaffold board 1 is lifted, the movable hook 4 becomes the locking position at the position where the scaffold board 1 is substantially horizontal, as shown in FIG. As described above, when the movable hook 4 rotates from the retracted position to the locking position, the fixing pin 17 moves over the lower wall 19 of the frame 5a to the concave portion 21 so that the movable hook 4 is automatically at the locking position. And the attachment of the scaffold board 1 to the scaffolding frame 100 is completed. Note that after the movable hook 4 is fixed by the fixing pin 17, the knob 17b of the fixing pin may be rotated as indicated by an arrow 91 and stored in the frame 5a.

  In addition, as described above, after the scaffolding plate 1 is attached to the horizontal round member 101, the scaffolding plate 1 is configured to be able to pass through the openings 10 and 15 only when moving to the oblique side. Even when an external force in the vertical direction to push up is applied, the fixed hook 3 and the movable hook 4 are not easily detached from the horizontal round member 101 by the locking pieces 9 and 14. In other words, the scaffold plate 1 is prevented from falling off the horizontal round member 101 due to the difference in angle between when the scaffold plate 1 is attached and after the attachment.

  Further, when the scaffold board 1 is removed from the scaffold building frame 100, the engagement of the fixing mechanism 16 is released by pulling the knob 17 b of the fixing pin 17 and removing the fixing pin from the recessed portion 21. Is movable, the movable hook 4 is moved to the retracted position, and the locking from the horizontal round member 101 is released. Thereafter, by lifting the fixing hook 3 side while the scaffolding plate 1 is inclined obliquely, the engagement of the fixing hook 3 is released and the removal of the scaffolding plate 1 is completed.

  As described above, according to the present embodiment, since the fixed hook 3 and the movable hook 4 are provided at both ends of the scaffold plate body, the movable hook 4 is moved to the retracted position for assembly, and the one end side The movable hook 4 can be locked to the horizontal round member 101 by locking the fixed hook 3 provided to the horizontal round member 101 and then lifting the other end of the scaffolding plate 1. Further, with the lifting operation, the movable hook 4 rotates from the retracted position to the locking position, and is further fixed at the locking position by the fixing mechanism 16. Therefore, it is not necessary to lift the entire scaffold plate for assembling, and the assembling work can be facilitated.

  The fixed hook 3 and the movable hook 4 form upper arcs 8 and 13 that form an arc upward with respect to the connecting legs 3a and 4a, and an arc that is continuous with the upper hooks 8 and 13 downward from the connecting legs 3a and 4a. Since the engaging pieces 9 and 14 are provided, the openings 10 and 15 exist at positions obliquely outward as viewed from the center of the arc, and the assembly to the horizontal round member 101 is performed from the oblique direction. On the other hand, after the scaffolding plate 1 is attached, the scaffolding plate 1 is disposed substantially horizontally, so that the locking pieces 9 and 14 of the fixed hook 3 and the movable hook 4 enter the lower side of the horizontal round member 101. For this reason, even when a vertical external force is applied from the lower side at the time of attachment, the locking pieces 9 and 14 do not remove the fixed hook 3 and the movable hook 4 from the horizontal round member 101, thereby ensuring safety during use. be able to.

  In addition, this invention is not limited to the said embodiment, It can implement in another various aspect. For example, the fixing mechanism is not limited to the above-described embodiment, and the configuration is particularly limited as long as the movable hook 4 at the locking position can be fixed to the scaffold plate body 2 and can be released by an easy operation. It doesn't matter.
