Description

  The present invention relates to a scaffolding skirting board, and more specifically, a scaffolding width that is installed upright on a side edge of a scaffolding plate in a temporary scaffolding in order to prevent an operator from falling down or dropping tools and the like. Regarding wood.

  In order to strengthen measures to prevent the fall from temporary scaffolding in the construction industry, etc., part of the Occupational Safety and Health Rules was revised regarding measures to prevent the fall from temporary scaffolding. It became obligatory to install skirting boards around the board (floor material).

  Conventionally, for safety measures, a baseboard was also installed around the scaffolding plate in the temporary scaffolding, but in many of the installation methods, the baseboard made of a plate material was used to construct the temporary scaffolding ( It was tied to a pedestal with a wire (thick wire). Therefore, the installation work is extremely troublesome, it takes work time, and there is a risk that the baseboard will come off if the tightening of the number wire is insufficient, and the number wire is cut when the scaffold is dismantled, so it becomes chips, There was a problem that it could not be used repeatedly. Therefore, in recent years, various scaffolding baseboards for solving these problems have been proposed.

  FIG. 4 is a diagram for explaining the scaffolding skirting disclosed in the following Patent Document 1, and (a) is a perspective view showing a state before the scaffolding skirting is installed on the scaffolding board. And (b) is a perspective view showing a state after the scaffolding skirting board is installed on the scaffolding board. In addition, in FIG. 4, although the one end side of the scaffolding baseboard is shown, the other end side is also the same structure.

  In the figure, reference numeral 60 denotes a scaffolding skirting board. The scaffolding skirting board 60 has a skirting board body 61 installed upright on the side edge of the scaffolding board 51. At each of the front and rear ends, an end cap 62, an out guide 63 supported by the outer end surface of the scaffolding plate 51, a catch guide 64 hooked to the horizontal member 52 of the scaffolding frame, and the catch guide 64 Locking means 65 is provided that engages and locks the horizontal member 52.

  The catch guide 64 is pivotally supported by the end cap 62 so as to swing in the front-rear direction in a suspended state, and the lower end hooking portion 64 a thereof is in contact with the front and rear end surfaces of the scaffold plate 51 at a position close to the inner surface of the scaffold plate locking hook 53. It is inserted between the scaffolding frame and the horizontal member 52, and is locked to the horizontal member 52 by the lock means 65.

  The locking means 65 includes a lock pin 67 that is attached to the end cap 62 so that the catch guide 64 can be moved forward and backward from the catch guide 64 at a position below the pivot 66 of the catch guide 64, and the catch guide 64 is always unlocked. The lock pin 67 has a bent portion 67a at the rear end, and pushes the lock pin 67 forward against the urging force of the spring 68. After the catch guide 64 is engaged with the horizontal member 52 of the scaffold for the scaffolding, the lock pin 67 is rotated by a required angle, and the rear end bent portion 67a is engaged with the stopper 69 to thereby catch the catch guide. 64 is locked.

  However, since the scaffolding skirting board 60 described in Patent Document 1 has a large number of components, the manufacturing cost is high, and the lock pin 67 is operated to lock the catch guide 64 and to release the lock. Was cumbersome. Further, since the end caps 62 are provided so as to cover both side end surfaces of the skirting board main body 61, even when a member having a substantially U-shaped cross section is used for the skirting board main body 61, When stacking a plurality of skirting boards during transportation, the end cap 62 becomes an obstacle and cannot be stacked compactly (with the U-shaped concave surfaces engaged with each other), resulting in a bulky problem. It was.

FIG. 1 is a view showing a scaffolding baseboard according to an embodiment, (a) is a front view seen from the outer surface side, (b) is a rear view, and FIG. 2 (a) is a right side view. FIG. 2 (b) is a left side view.

  In the figure, reference numeral 1 denotes a scaffolding baseboard that is hooked on a horizontal member constituting a temporary scaffold and is installed upright on a side edge of a scaffolding plate that is installed between the horizontal members. The scaffolding skirting board 1 includes a baseboard body 2 formed to have a predetermined length and width according to the distance between the horizontal members constituting the temporary scaffold, and a locking hook for the scaffolding plate laid between the horizontal members. In order to be hooked on the horizontal member in a state where the frame is sandwiched, latching members 11A and 11B having a pair of latching pieces 12 respectively attached downward from both ends of the baseboard body 2 are provided. .

  The skirting board body 2 is a member (C) in which substantially L-shaped folded walls 2b and 2c to the outer surface side are formed on the upper and lower end portions of the standing face plate 2a having a predetermined length and width using aluminum, a steel plate, or the like. And a substantially L-shaped cutout portion 3, 4 is formed at the lower part of both ends. The length L of the skirting board main body 2 is set to be shorter by about 4 mm to 9 mm than the center axis distance La (see FIG. 3) between the horizontal members. For example, when the prescribed center axis distance La is 1829 mm, the corresponding length L of the baseboard body 2 is set to 1825 mm.

  The latching members 11A and 11B are made of aluminum, steel plate or the like, and a pair of latching pieces 12 are spaced from the lower end of a substantially rectangular mounting plate 13 attached to the end of the upright plate 2a (ie, adjacent scaffolding plates). ) Is provided so as to be integrally formed in a downward substantially U-shape (bifurcated shape).

  One latching member 11A rotates to a latching position for latching the latching piece 12 on the horizontal member and an open position for releasing the latching piece 12 latched on the horizontal member from the horizontal member. It is pivotally attached to the skirting board body 2 and is attached in a state where the latching piece 12 is urged by the tension spring (elastic member) 20 in the direction of the latching position (arrow B direction).

  That is, a bolt hole (not shown) into which the bolt 21 is inserted is formed at a position above the center of the left end portion of the standing surface plate 2a when viewed from the back, and is positioned below the center of the left end portion of the standing surface plate 2a when viewed from the back. A long hole 5 for defining a range in which the latch member 11A is pivoted between the latch position and the open position with the bolt 21 as the pivot center is formed at the upper position of the notch 3). The mounting plate 13 of the member 11A is pivotally attached to the outer surface side end portion of the upright plate 2a by bolts 21 and nuts 22 and is slidably engaged along the long holes 5. The nut 24 is coupled so that the rotation range of the latching member 11A is restricted.

  Further, one end side of a tension spring 20 that biases the upper end of the mounting plate 13 inward is locked to the spring locking portion 14 formed at the upper end of the mounting plate 13 of the latching member 11A. The other end side is locked in a locking hole 6 formed in the standing surface plate 2a. The locking hole 6 is preferably formed at a position above the center of the upright plate 2a so that the angle formed by the attachment plate 13 of the latching member 11A and the tension spring 20 is about 90 °.

For example, the tension spring 20 has a wire diameter of about 2 mm, a winding number of around 17, a coil outer diameter of about 15 mm, a length of about 50 mm, and a spring constant (k). A tension coil spring designed to be about 1.27 to 1.50 (N / mm) may be employed. The spring constant (k) is a proportional constant obtained by dividing the load P (N) by the elongation (displacement δ) (mm) when a load is applied to the spring, that is, k = P / δ (N / mm). ) Indicates a constant that can be expressed.
By using the tension spring 20 having the above-described spring constant, attachment and detachment can be performed with a force that does not burden the operator, and the scaffolding skirting board 1 is horizontally mounted using the elastic force of the spring. It becomes possible to attach to the stable standing state between materials.

  The other latching member 11B is fixed to the skirting board main body 2. That is, a bolt hole (not shown) into which bolts 25 and 26 for fixing the mounting plate 13 of the latching member 11B are inserted at the upper position and the lower position from the center of the right end of the upright face plate 2a in the back view. The mounting plate 13 of the latching member 11B is fixed to the outer surface side end of the upright plate 2a by bolts 25, 26 and nuts 27, 28 mounted in these bolt holes. In addition, the method of crimping using the rivet other than the said method can apply the method of adhering the latching member 11B to the baseboard main body 2. FIG.

  An inclination guide portion 12a is formed at the lower end portion of each of the engagement pieces 12 of the engagement members 11A and 11B, and an engagement portion 12b having a substantially arc shape is formed on the upper end portion of the inclination guide portion 12a. . Further, the upper end portion of the inclined guide portion 12 a is formed so as to be located inward from the upper end portion of the arc of the hook portion 12.

  Next, a procedure for attaching the scaffolding skirting board 1 according to the embodiment between the horizontal members of the temporary scaffolding will be described. FIGS. 3A to 3C are diagrams for explaining a procedure for attaching the scaffolding baseboard according to the embodiment between the horizontal members of the temporary scaffolding, as viewed from the outer surface side of the baseboard body 2. FIG.

  In the figure, 40a and 40b indicate horizontal members constituting the temporary scaffold, and 41a, 41b and 41c in the figure indicate scaffold plates. Although the overall structure of the temporary scaffolding is not shown, in general, a large number of building frames, in which horizontal members are horizontally stretched between a pair of left and right pedestals, are arranged horizontally or vertically at predetermined intervals. In addition to being arranged side by side, scaffolding plates are bridged between the horizontal members of adjacent building frames, and braces are provided between corresponding pedestals of adjacent building frames.

3 (a) to 3 (c) show a case where the scaffolding skirting board 1 is attached next to the scaffolding skirting board 1A having the same structure that has been previously attached.
First, as shown to Fig.3 (a), the latching | locking part 12b of the latching piece 12 of one latching member 11B fixed to the baseboard main body 2 is made into the latching hook 42 of the scaffolding boards 41a and 41b. It is hooked on the horizontal member 40a in a state where it is sandwiched (stretched). Next, the inclined guide portion 12a of the latching piece 12 of the other latching member 11A is placed on the horizontal member 40 with the locking hooks 42 of the scaffolding plates 41b and 41c being sandwiched (stradded).

  Since the length L of the baseboard body 2 is set to be about 4 mm to 9 mm shorter than the distance La between the central axes between the horizontal members 40a and 40b, as shown in FIG. Even in a state where 2 is tilted obliquely, it is possible to prevent contact with or interference with the scaffold baseboard 1A that is installed next to it.

  Next, when the baseboard body 2 on the side of the latching member 11A of the scaffolding baseboard 1 is pushed downward with a required force, as shown in FIG. 3B, the latching piece of the latching member 11A While the 12 inclined guide portions 12a are pressed against the horizontal member 40b, the latching member 11A rotates in the direction of the open position (direction of arrow A) against the tensile force of the tension spring 20. To go.

  And when the upper end part of the inclination guide part 12a of the latching piece 12 of the latching member 11A is pushed further down beyond the side top part of the horizontal member 40b, the latching member 11A is pulled by the tensile force of the tension spring 20. As shown in FIG. 3 (c), the latching portion 12b of the latching piece 12 is latched in a pressed state on the horizontal member 40b and attached. Is completed.

  Further, when removing the scaffolding skirting board 1 attached between the horizontal members 40a and 40b, an operation of pulling up the hanging member 11A side of the skirting board main body 2 with a required force or more may be performed. When the operation of pulling up the latch member 11A side of the skirting board body 2 is performed, the latch member 11A starts to rotate in the direction of the open position (arrow A direction) against the tensile force of the tension spring 20, and the latch The upper end portion of the inclined guide portion 12a of the latching piece 12 of the member 11A moves further upward beyond the side top of the horizontal member 40b, and the latching piece 12 of the latching member 11A is detached from the horizontal member 40b. . If it pulls up upwards in that state, the baseboard 1 for scaffolding can be removed from between the horizontal members 40a and 40b.

  According to the scaffolding skirting board 1 according to the above-described embodiment, one of the hooking members 11A can rotate the hooking piece 12 between the hooking position and the opening position (in the directions of arrows B and A). 2, and the latching piece 12 is urged by the tension spring 20 in the direction of the latching position (arrow B direction). Moreover, the inclination guide part 12a is formed in the lower end part of the latching piece 12 of 11 A of latching members, and the upper end part of the inclination guide part 12a is located inward rather than the circular arc upper end part of the latching part 12b. .

  Therefore, the latching member 11A can be latched only by pressing the inclined guide portion 12a of the latching piece 12 of the latching member 11A pivotally attached to the baseboard body 2 from above (see FIG. 3). The piece 12 automatically rotates in the direction of the open position (arrow A direction), and then the locking portion 12b is hooked to the horizontal member 40b by the urging force of the tension spring 20 in a pressed state. The skirting board 1 can be attached to the horizontal members 40a and 40b in a stable state without any looseness by one touch. Moreover, when removing, the latching piece 12 of 11 A of latching members is made into the urging | biasing force of the tension | pulling spring 20 only by lifting up the baseboard body 2 by the side of the latching member 11A pivotally attached to the skirting board main body 2. FIG. Accordingly, the latching portion 12a can be easily detached from the horizontal member 40b by rotating in the direction of the open position (arrow A direction), and the working efficiency can be further enhanced. In addition, the number of components to be formed is small, the fabrication thereof is easy, the production cost can be suppressed, and an inexpensive scaffolding skirting board can be provided.

  Further, the skirting board main body 2 is configured by a member having a substantially C-shaped cross section in which folded walls 2b and 2c are formed on the upper and lower ends of the standing surface plate 2a, and the mounting plate 13 of the latching member 11A is It is pivotally attached to the outer surface side end portion of the upright plate 2a in which the long hole 5 is formed, and is coupled to the engagement shaft engaged with the long hole 5 so that the upper end of the mounting plate 13 is spring-engaged. The part 14 and the upright plate 2a are connected via an extension spring 20 so as to urge the upper end of the mounting plate 13 inward. Therefore, when the scaffolding skirting boards 1 are stacked at the time of storage and transportation, the outer surface side (concave surface) of the skirting board main body 2 faces each other and is compactly bulky in a state where the folded wall portions 2b and 2c are engaged with each other. They can be overlapped without any other, storage space can be reduced, transportation costs can be reduced, and light weight and excellent handling can be achieved.

  In addition, since the length of the baseboard body 2 is set to be 4 mm to 9 mm shorter than the center axis distance La between the horizontal members, as shown in FIG. The latching portion 12b of the latching piece 12 of one latching member 11B is latched to the horizontal member 40a, and the inclined guide portion 12a of the latching piece 12 of the other latching member 11A is applied to the horizontal member 40b. Even in a state where the baseboard body 2 is tilted obliquely, it is possible to prevent contact with or interference with the scaffold baseboard 1A already installed next to the baseboard body 2.

  Therefore, in order to avoid contact and interference with the existing baseboard 1A for the scaffolding when attaching to or removing from the scaffolding, the latching position of the latching piece 12 of the latching member 11B is set to the axis of the horizontal member 40a. The work and trouble of shifting in the direction can be eliminated, and the workability at the time of attachment and removal can be further enhanced. Moreover, the space | interval with an adjacent baseboard can be made narrower than 10 mm.

  In the above embodiment, only one of the latching members 11A is pivotally attached to the skirting board body 2 and the latching piece 12 is urged toward the latching position by the tension spring 20. As described above, in another embodiment, the latching members 11A and 11B on both sides are pivotally attached to the skirting board body 2 in the same manner as the latching member 11A described above, and the latching pieces are latched by the tension spring 20. 12 may be configured to be biased in the direction of the latching position.
