Description

  The present invention relates to a baseboard to be attached to a scaffolding plate of a framework scaffold installed at a construction work site or the like.

  In a high place work on a scaffolding plate of a framework scaffolding installed at a construction work site or the like, parts such as bolts, metal fittings and tools placed by the operator may be accidentally dropped.

  In the construction industry, etc., there are many occupational accidents due to crashes and falls from high places. This time, in order to strengthen measures to prevent crashes from scaffolds, etc., crashes from scaffolds, construction passages and work platforms A part of the occupational safety and health regulations regarding the preventive measures, etc. has been revised and will come into effect on June 1, 2009.

  The contents are enhancements such as measures to prevent the fall from the scaffold, and the following measures to prevent the fall are necessary depending on the type of scaffold. Even in the framework scaffolding, in order to prevent a fall from the gap at the bottom of the cross brace, in addition to the cross brace, it is mandatory to install "Mr. Shimo" or "Nagashi", or "Handrails" It is done.

  Even in the framework scaffolding, it has been conventionally done to attach a baseboard to the side edge of the scaffolding board, but there is no fixed attachment method, for example, a strip-like board material in the form of a dam plate on the side edge of the scaffolding board They are standing and tied to the support of the framework scaffolding with wires and wires.

  However, in such a method, it took time and labor to attach and remove the baseboard, and the workability was not good.

Then, there exists a thing shown in the following patent document 1 as a baseboard which eliminates this inconvenience and is attached to a scaffold board in one touch. This is because the set fitting is pivotally mounted on the outer surface side of the baseboard body so as to be swingable between a vertical posture and an inclined posture in which the lower portion protrudes outward, and a plurality of projections projecting downward from the lower surface of the baseboard body An upright bracket, and the set bracket is biased to the vertical posture side by a spring force, and has an inwardly engaging portion at a lower portion protruding downward from the baseboard body in the vertical posture, and the upright bracket Is inserted into the attachment hole in the side edge of the scaffolding plate from above, and the side edge is fitted between the lower surface of the baseboard body and the locking part of the set fitting.
Japanese Patent No. 3439684

  In the above prior art, the baseboard can be attached in a one-touch manner, but the baseboard is directly fixed to the scaffolding plate with a set bracket, and the set bracket only holds the scaffold plate from the outside in the vertical direction. For this reason, if the lower side of the set fitting is pushed by some external force, it may be easily removed even during work, and it is necessary to make a mounting hole in the scaffold plate.

  In recent years, due to the revision of the Occupational Safety and Health Rules, it was obliged to install a baseboard with a predetermined height or higher with respect to the scaffolding plate of the frame scaffolding. Productivity is not good.

  The present invention eliminates the inconvenience of the conventional example, and can easily fix the baseboard to the scaffolding board with a simple structure. After the fixing, there is no risk of detachment even if an external force is applied, and the mounting can be performed with one touch. Thus, the present invention provides a baseboard for a scaffold board that can be easily applied to a ready-made scaffold board.

  In the first aspect of the present invention, a downward vertical hook as a fixing member to the pipe of the scaffolding and a horizontal hook project in the length direction of the baseboard body on the outer surface side of the end portion of the baseboard body, The gist of the hook is that it can be slid horizontally by a slide rod.

  According to the first aspect of the present invention, the baseboard body is locked and fixed to the horizontal pipe and the vertical pipe, which form a scaffold by the vertical hook and the horizontal hook, respectively. Therefore, the baseboard body is not fixed directly to the scaffolding plate, but is also fixed in two directions, the horizontal and vertical directions. Further, since it is locked by the hook, it is difficult to come off by an external force and is securely fixed. . Moreover, since it is only necessary to attach the hook, it can be easily done with one touch.

  Furthermore, in the present invention, when the vertical hook and the horizontal hook are provided, it is important that the horizontal hook can be laterally slid by the slide rod. If both are fixed, it is difficult to align and difficult to hang simultaneously on the horizontal pipe and the vertical pipe forming the scaffold, but this is facilitated by making the horizontal hook slidable. If the vertical hook is hung first and the baseboard body is laid down, the horizontal hook can be easily hung on the vertical pipe.

  According to the second aspect of the present invention, the vertical hook and the horizontal hook are formed in a U-shaped notch in the plate-like body, and are formed so that the protruding step is opposed to the inner periphery of the notch. The gist is that a narrow portion is provided at the entrance.

  According to the second aspect of the present invention, the vertical hook and the horizontal hook are formed in the U-shaped notch in the plate-like body, and the protruding step is formed on the inner periphery of the notch, Since the narrow part is provided at the notch entrance, the horizontal hook is hooked to the horizontal pipe and the horizontal hook is hooked to the vertical pipe. The pipe is difficult to come out in the narrow part. Detachment prevention is obtained.

  Furthermore, this protruding step hardly causes any trouble when a horizontal pipe or a vertical pipe is inserted into the U-shaped notch.

  The gist of the present invention described in claim 3 is that the horizontal hook is attached to the baseboard body by a spring member so as to be able to protrude and retract.

  According to the third aspect of the present invention, since the horizontal hook is attached to the baseboard body by the spring member so as to be able to protrude and retract, the horizontal hook can be stored in the baseboard body and becomes an obstacle when the vertical hook is locked to the horizontal pipe. There is nothing.

  According to a fourth aspect of the present invention, the baseboard body is formed by bending the upper end of the vertical plate into an L-shape facing downward and providing a horizontal projecting piece facing inward at a slightly upper portion of the lower end to place the baseboard on the scaffolding plate. The gist of this is

  According to the fourth aspect of the present invention, since the bent portion from the upper end of the baseboard body and the horizontal projecting piece at the lower end protrude in opposite directions on the outer side and the inner side, respectively, the baseboard main body is stacked when stored. When stacking alternately, it can be stacked horizontally without waste.

  As described above, the baseboard for a scaffold board according to the present invention has a simple structure in which a hook is attached to the baseboard body, and the baseboard is fixed to the scaffold board because it is hooked to the pipe of the scaffold. Compared to the case, it can be fixed securely. After fixing, there is no risk of disengagement even if an external force is applied, and it can be easily attached with one touch, and can be easily implemented on a ready-made scaffolding plate.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view showing an embodiment of a baseboard for a scaffold board according to the present invention, FIG. 2 is a side view of the main body of the baseboard, and the baseboard 1 of the present invention is attached to a scaffold board 3 of a frame scaffold. As a basic structure, vertical ends that are respectively hooked to the horizontal pipe 4 and the vertical pipe 5 of the frame scaffolding in the length direction of the baseboard body 2 at both ends of the baseboard body 2 constituted by a belt-like plate body. The hook 6 and the horizontal hook 7 were protruded and attached.

  As shown in FIG. 2, the baseboard body 2 is a scaffolding plate as a horizontal protruding piece 2a by bending the upper end of a strip-shaped metal plate made of a steel plate or the like into an outward L-shape and bending the upper part of the lower end horizontally inward. It was set as the mounting part to 3.

  As shown in FIGS. 1 and 3, the vertical hook 6 is formed by forming the tip of the plate-like body 6 a into a downward U-shaped notch and hooking the notch on the horizontal pipe 4 of the frame scaffold from above. It formed in the stop part 6b.

  The U-shaped notch of the vertical hook 6 is formed so that the protruding step 13 is opposed to the inner periphery of the notch, and the narrow portion 14 is provided at the notch entrance.

  The inner side from the protruding step 13 has a circumferential surface that is more than a semicircular circumference of the horizontal pipe 4, and the step of the protruding step 13 has an inclination that leads from the outside to the narrowed portion 14 toward the outer opening. Let

  The vertical hooks 6 are attached to the left and right ends of the baseboard body 2 and project oppositely from the end portions of the baseboards 1 that are continuously connected. The vertical hooks 6 project from the adjacent baseboards 1. As shown in FIG. 3, the projecting positions are varied within the horizontal width direction of the baseboard body 2 so that they do not collide with each other.

  Specifically, the vertical hook 6 is formed in an inclined portion 6c in which the base portion of the plate-like body 6a is abutted against the baseboard body 2 and fixed with a bolt, and a protruding portion from the baseboard body 2 is bent obliquely outward. Further, the latching portion 6b is formed in the vertical plate-like portion at the tip, and in this case, the width of the inclined portion 6c is made different between the left and right of the baseboard body 2.

  In the case shown in FIG. 3, the oblique portion 6 c is 15 mm on the right side of the baseboard body 2, but is 20 mm on the left side. As a result, the vertical hooks 6 protruding from adjacent baseboards 1 to be connected can be mutually inserted and can be hooked on the same horizontal pipe 4.

  The horizontal hook 7 is attached to the baseboard body 2 at a position above the vertical hook 6, and a first example is shown in FIGS. 4 to 7. The horizontal hook 7 is provided with a horizontal U-shaped notch at the tip of the plate-like body to form a hooking portion 7a for the vertical pipe 5, and the plate-like body on which the locking portion 7a is formed is slid by welding or the like. Fix to 8.

  Like the vertical hook 6, the horizontal hook 7 also has a U-shaped notch formed with a protruding step 13 facing the inner periphery of the notch, and a narrow portion 14 is provided at the notch entrance.

  The inner side from the projecting step 13 has a circumferential surface that is more than a semicircular circumference of the vertical pipe 5, and the step of the projecting step 13 has an inclination that leads from the outside to the narrow portion 14 toward the outer opening. Let

  In the vicinity of the rear end of the slide rod 8, a locking recess 8a for the leaf spring 11 described later is provided.

  The means for attaching the slide rod 8 to the baseboard body 2 is a horizontally long U-shape in which a mounting plate 9 is fixed to the outer surface of the baseboard body 2 with bolts, and a band plate member is bent on the outer surface of the mounting plate 9. The support member 10 is fixed by welding or the like. In this case, the support member 10 is longer than the attachment plate 9, and the rear portion of the support member 10 protrudes rearward from the attachment plate 9.

  The support member 10 is formed with insertion holes for the slide rods 8 at the rising portions at both ends of the U-shape. As a result, the slide rod 8 is slidably supported by the support member 10.

  A leaf spring 11 is attached to a gap formed outside the mounting plate 9 on the inner surface side of the rear portion of the support member 10. The leaf spring 11 protrudes rearward from the support member 10, and a 90-degree bent portion toward the outside is formed in a mountain shape on the protruding portion, and the bent portion is a latch provided on the slide rod 8. It becomes the latching protrusion 11a to the recessed part 8a.

  In order to attach the baseboard 1 to the scaffold board, as shown in FIG. 2, the baseboard 1 is disposed on the side edge of the scaffold board 3, and the horizontal protrusion 2a is placed on the scaffold board 3, as shown in FIG. The hook 6b of the vertical hook 6 is hooked from above on the horizontal pipe 4 constituting the frame scaffold. In this case, the vertical hooks 6 project from the opposing scaffolding plates in a face-to-face relationship between the continuous scaffolding plates, but the vertical hooks 6 project in a misplaced manner as described above. It does not hit and is hooked on the same horizontal pipe 4 in parallel.

  In this state, since the hooks 6b are formed downward in the vertical hook 6, there is no possibility that the vertical hook 6 is detached from the horizontal pipe 4 when the load of the baseboard body 2 is applied.

  If the horizontal pipe 7 or the vertical pipe 6 gets in the way when the vertical pipe 6 is locked, the slide rod 8 can be slid backward along the support member 10 against the elasticity of the leaf spring 11 to hang it. The stop 7b is immersed in the baseboard body 2.

  In this way, when the horizontal hook 7 is pulled out from the baseboard body 2 and the latching portion 7a is inserted into the vertical pipe 5 and latched, the baseboard body 2 has already been locked with the vertical hook 6 on the horizontal pipe 4. However, it is possible to move the horizontal hook 7 to the vertical pipe 5 without obstructing the baseboard 2 by tilting the baseboard body 2 at an angle. If the baseboard body 2 is set up vertically at a place, it is possible to easily and quickly lock the baseboard body 2.

  When the vertical hook 6 is attached to the horizontal pipe 4 as described above, the horizontal hook 7 is then pulled out from the baseboard body 2 and the latching portion 7a is inserted into the vertical pipe 5 and latched. In this state, the locking protrusion 11a of the leaf spring 11 is elastically fitted into the locking recess 8a formed on the slide rod 8, and the horizontal hook 7 is fixed to the baseboard main body 2 at that position, from the vertical pipe 5. There is no fear of coming off.

  In this way, the vertical hook 6 and the horizontal hook 7 are fixed to the horizontal pipe 4 and the vertical pipe 5 of the frame scaffolding, whereby the baseboard 1 is disposed on the side edge of the scaffold plate.

  When the skirting board 1 is not used, the skirting board main body 2 is horizontally lowered and stacked as shown in FIG. In this case, the baseboard body 2 in the up-and-down position is stacked upside down so that the horizontal protrusions 2a protrude upward and downward. Thereby, it is stacked in a stable state without generating a useless space and without causing a lateral shift.

  In addition, the engagement between the leaf spring 11 and the slide rod 8 is such that the end of the slide rod 8 is in contact with the slope of the mountain of the leaf spring 11 in addition to providing the locking recess 8a in the slide rod 8 as described above. Also good.

That is, the end of the slide rod 8 gets over the leaf spring 11, and the slope of the mountain of the leaf spring 11 pushes the end of the slide rod 8. Even in this way, the slide rod 8 can be fixed by the urging force of the leaf spring 11.

  FIGS. 9 to 12 show a second example of the means for attaching the horizontal hook 7 to the baseboard body 2. Instead of the leaf spring 11 of the first example described above, the coil spring 12 is moved within the range of the support member 10. And a ring as a stopper 8 b was attached to the rear end of the slide rod 8. Other configurations are the same as those in the first example.

  As a result, as shown in FIG. 9B, the slide rod 8 and the horizontal hook 7 are urged in the protruding direction by the extension force of the coil spring 12, and the horizontal hook 7 protrudes from the baseboard body 2 so that the latching portion 7a is vertical. The pipe 5 is pressed and hooked.

  In this state, the horizontal hook 7 is applied with the pressing force in the direction of the vertical pipe 5 by the coil spring 12 as described above, so that the horizontal hook 7 does not come off the vertical pipe 5.

  Even when the horizontal hook 7 is not hooked to the vertical pipe 5, the horizontal hook 7 is urged by the coil spring 12 in the direction of protruding from the baseboard body 2, but after the slide rod 8 A stopper 8b is provided at the end, and as shown in FIG. 12, this abuts the outside of the support member 10, so that the slide rod 8 does not come out of the support member 10.

  In order to immerse the horizontal hook 7 in the baseboard body 2, the horizontal hook 7 may be pushed in against the elasticity of the coil spring 12.
