Description

  The present invention relates to a scaffold fixture that is engaged with a veranda end to fix a scaffold.

A scaffold for the construction worker is constructed when the construction of the upper part of the building is performed. In order to prevent the scaffold from falling over, the scaffold is fixed to the building.
Such fixation is often performed by penetrating the concrete surface of the building with the pipe connected to the scaffold as an anchor.
However, it is troublesome to penetrate the anchor into the concrete surface, and it is also necessary to refill the hole for the anchor after the construction is completed. Moreover, sufficient strength may not be able to be obtained by deterioration of the concrete of the part which penetrates an anchor.

In order to improve the problem of the anchor described above, a clamp has been engaged with a handrail portion of a building or a raised portion of a veranda. The handrail part of the building and the raised part of the veranda are close to the front, upper part and rear part, so clamps are applied to these three surfaces, and the clamps are crimped to the front part and the rear part with bolts etc. Supporting force is obtained by friction with the building (concrete surface).
However, since the clamp is hung only on the three surfaces, the clamp may move upward and come off, which is not necessarily safe enough.

In order to improve the above-mentioned problem of the clamp, Patent Document 1 discloses that one side of the clamp is extended downward and bent to be arranged under the end of the veranda and then extended upward from the end of the veranda. A clamp having a contact member (contact member) is disclosed. This clamp has no possibility of moving upward and coming off.
However, the clamp disclosed in Patent Document 1 has the following problems and is not suitable for use at a construction site. (1) In a state immediately after the clamp is hung on the end of the veranda, the contact member is at least the length of the margin of the rear end of the veranda end of the clamp with respect to the lower end of the end of the veranda (considered to be 100 mm or more). Only below. It takes time to move the contact member by this length. This is because the bolt is rotated and moved in order to maintain the support strength of the contact member. (2) The operation of moving the contact member is performed on the scaffold. It becomes work on the scaffold before it is completely fixed. As described above, this operation takes time, and therefore it is not always preferable.

It maintains the strength of fixing the scaffolding with a connecting rod.
The “upper side” does not have to be directly above the clamp body, and may be directly above as shown in FIG. 5A or may be on the upper side as shown in FIG. . What is necessary is just to set it as the location which does not interfere with another member.

  ADVANTAGE OF THE INVENTION According to this invention, it can provide the scaffold fixing tool by the clamp which does not move and move out upwards, Comprising: A thing which can be installed in a short time can be provided. Furthermore, what can be installed on the veranda instead of on the scaffolding can be provided according to the implementation form of the device.

FIG. 1 is a diagram illustrating a scaffold fixture. Example 1 FIG. 2 is a diagram illustrating an installation procedure of the scaffold fixture. Example 1 FIG. 3 is a diagram showing a scaffold fixture. (Example 2) FIG. 4 is a diagram showing an installation procedure of the scaffold fixture. (Example 2) FIG. 5 is a diagram showing a connecting rod. (Example 3)

FIG. 1 is a diagram illustrating a scaffold fixture. The figure is a cross-sectional view, showing the components inside the clamp. The veranda end 1 has a rear part 11, an upper part 12, a front part 13 and a lower part 14. The clamp body 2 is hung on the rear part 11, the upper part 12 and the front part 13.
The sliding bar 3 is connected to the front side of the clamp body 2 and is fixed by a nut 31. The sliding bar 3 passes through the hole of the support 4 and has a screw thread that becomes a bolt in the vicinity of the hole of the support 4. A nut that fits the bolt is provided as the position adjusting mechanism 5. The position adjustment mechanism 5 can adjust the vertical position of the support 4 to engage the support 4 with the lower part 14 of the veranda end 1.
A catch bolt 6 is provided on the rear side of the clamp body 2. A connecting rod 7 for connecting a scaffold is provided on the front side of the clamp body 2.

In order to provide the position adjustment mechanism on the upper side of the clamp body, a part of the structure is a scaffold fixture different from that of the first embodiment. Other portions are the same as those in the first embodiment, and detailed description thereof is omitted.

FIG. 3 is a diagram showing a scaffold fixture. The figure is a cross-sectional view, showing the components inside the clamp. A hole is provided on the front side of the clamp body 2, and the sliding bar 3 penetrates the hole and is exposed on the upper side of the clamp body 2. A position adjusting mechanism 5 that is a nut is provided in the exposed portion.
FIG. 4 is a diagram showing an installation procedure of the scaffold fixture. The figure is not a sectional view but a side view of the scaffold fixture. The support 4 and the sliding bar 3 rotate as a unit with respect to the clamp body 2. Using this fact, the clamp body is hung on the end of the veranda as shown in (a), and the support 4 is engaged with the lower part of the end of the veranda as shown in (b). Can be used to install scaffolding fixtures.
The operation of the position adjusting mechanism 5 and the operation of rotating the support 4 and the sliding bar 3 (rotating with the upper end of the sliding bar 3) can be performed on the veranda. A scaffolding fixture can be safely installed.

  In this embodiment, the strength of the connecting rod is obtained. Portions other than the connecting rod are the same as those in the first and second embodiments, and detailed description thereof is omitted.

  FIG. 5 is a diagram showing a connecting rod. As shown in (a), the holder 8 is provided on the upper part of the clamp body 2 and the connecting rod 7 is held. A hole is provided in the connecting rod 7 and a pin 9 is inserted. The connecting rod 7 is stably fixed by the pin 9 and is not rotated by the holder 8 with respect to the pin 9.

  When the connecting rod of the present embodiment is used for the scaffold holder of the second embodiment, the sliding bar 3 and the connecting rod 7 may be located at different positions as shown in (b).

  It is a scaffold fixing tool by a clamp that does not move and move upward, and can be installed in a short time, and can be installed on a veranda instead of on a scaffold. It can be used by many construction contractors.
