Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a scaffolding plate mounting metal fitting for construction work, and comprises a metal arm fitting that can be easily and directly attached to a pillar during construction work, and a metal arm hooked on this.

[0002]

[Prior art]

 Conventionally, this kind of scaffolding plate mounting bracket 1 is known to have various structures, but the one as shown in FIG. 6 requires labor and time to adjust the bracket due to the size of the pillar or the like. In addition, the metal fittings were large and difficult to handle.

Further, the one as shown in FIG. 7 is a system in which the support receiver is attached to the pillar with nails and the support body is inserted, but the pillar may be damaged. Moreover, it was difficult to position the support receiver when the scaffold plate was mounted horizontally.

[0004]

[Problems to be solved by the device]

 The problem to be solved is that the conventional scaffolding plate mounting bracket 1 is large and difficult to handle, and if the support receiver is attached to the pillar with nails or the like, the pillar may be scratched or it is difficult to position the support receiver. there were.

[0005]

[Means for Solving the Problems]

 Therefore, in this plan, the metal fittings are small, lightweight, and easy to handle.The metal fittings are separated into the arm fittings, and the fitting method of the arm fittings to the pillar is lightweight, high strength, and familiar with the square pillar. It is secured by using a good synthetic fiber belt.

In addition, a belt having a buckle at one end is provided at the scaffolding plate mounting portion of the armor to fix the scaffolding plate to prevent the scaffolding from rising.

【Example】

 An embodiment of the present invention will be described below. It is composed of a bracket attachment 2 that is fastened and fixed to a column, and a bracket 4 that is inserted into a slit 23 of the attachment bracket 2. Consists of a main body 21 having a U-shaped cross section and a fastening member 3, and the main body 21 has a U-shaped cross section, and has notches 22 having a width corresponding to the pillars on the upper and lower surfaces thereof. A pair of vertically elongated slits 23 are provided from the upper part of the front surface to the central portion, and hooks 24 are provided at one outer ends of the slits 23, and a through hole 25 for a fastening bolt 31 is provided at the other end. A safety piece 26 having a U-shaped cross-section is rotatably mounted on the front center upper part of the main body 21 by a shaft 27. In addition, even a thin iron plate can be squeezed for strength, and U-shaped ribs on both sides. Is provided.

The fastening member 3 includes a fastening belt 34 made of narrow weave made of synthetic fiber and having an engaging ring 35 at one end and a fastening bolt 31 at the other end via a mounting ring 33. Is. The engagement ring 35 of the fastening member 3 engages with the hook 24 described above, and the fastening bolt 31 penetrates the hole 25 and is screwed with the rear fastening nut 32.

The arm 4 has a substantially square pipe shape on the base end side, and has a shape in which the lower side is largely cut off from the lower center portion toward the tip side, and the base end portion has the slit 23. The armrest hook 41 to be inserted is provided, and the scaffolding plate fixing piece 42 and the scaffolding plate mounting belt 5 are provided on the upper surface of the armrest.

The scaffolding plate mounting belt 5 is a narrow woven belt made of synthetic fiber, and has a buckle 6 sewn at one end thereof. The belt 5 is inserted into the upper surface of the arm 4 in a loop and fastened with a buckle 6.

Next, the attachment method will be described with reference to FIG. 4. First, the notch 22 of the main body 21 of the arm mount attachment 2 is applied to a predetermined position of the pillar, and the engagement ring 35 at one end of the fastening belt 34 is attached to the hook 24. Engage. Then, turn the tightening nut 32 with a wrench etc. to tighten it and attach firmly.

Next, the arm 4 is attached, but the safety piece 26 is rotated by a finger, the arm hook 41 is inserted into the slit 23, and when lowered, the hook 41 is fitted to the main body 21. it can. After that, when the finger is released from the safety piece 26 that was held by the fingers, the safety piece 26 rotates and stops toward the lower side, and even if the arm 4 is lifted, the lower end of the safety piece 26 and the upper surface of the arm 4 are stopped. Does not come in contact with and come off.

Next, the scaffold plate is placed on the upper surface of the arm 4 and fastened and fixed by the scaffold plate mounting belt 5. At this time, do as shown in Fig. 5, but if one of them is lowered, loosen the tightening nut 32 and raise the main body 21 of the arm mount fixture 2 along the pillar to easily set it almost horizontally. can do. Similarly, the opposite can be easily set.

[0014]

[Effect of device]

 Therefore, since the arm mount fixture 2 has a U-shaped cross section and a notch 22 having a width slightly larger than the width of the column in the center of the upper and lower surfaces, the arm mount fixture 2 is resistant to a lateral load. Fixture 2 does not twist. Furthermore, by inserting the arm hooks 41 of the arm 4 into the slits 23 provided at appropriate positions on the front, the arm 4 can be easily attached to the arm attachment 2, and the scaffold plate can be easily attached and detached. It can be done efficiently.

Further, if a large number of arm mount fixtures 2 are attached to the pillar, by mounting the armrests 4 as needed, the work can be carried out extremely efficiently when the scaffold plate is moved. .

Moreover, since the arm attachment 2 has two slits 23, the arm 4 is sandwiched in conformity with the slit 23, so that the arm 4 can be displaced left and right. It can be attached tightly to the arm mount fixture 2.

Then, even if an operator rides on the end of the scaffold plate attached by the scaffold plate attachment belt 5 provided on the armrest 4 and one of the armrests 4 floats up, the armature 4 is attached to the lower end of the safety piece 26. The upper surface of the base end does not come into contact with each other, and the arm member 4 does not come off from the arm member attachment 2. Further, from this fact, the entire length of the scaffold plate can be effectively used.
