Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a wall-connecting anchor for fixing scaffolding used in wooden buildings to the frame.

[Prior Art] In wooden buildings, scaffolding on one side is usually temporarily installed to ensure safety when working at heights. 1st side scaffolding is 5th
As shown in the figure, after the vertical members 15 and the horizontal members 16 are assembled in the shape of a parallel cross, a connecting plate 18 is used to connect the vertical members 15 or the horizontal members 16 and the pillars 17 of the frame. The connecting plates 17 are nailed with nails 19 or bound with wire or the like.

[Problems that the invention aims to solve] However, with conventional connecting boards that are tied together with nails or wire and fixed on both sides, the nails and wire tend to loosen during work, making it difficult to secure the scaffolding. It was. In addition, this connecting board can be used for underlayment,
It had to be removed from the frame before mortar could be applied. As a result, work such as laying the base and applying mortar had to be carried out in unstable conditions.

The purpose of the present invention is to provide a reusable wall anchor that ensures the safety of scaffolding.

[Means for Solving the Problems] In order to achieve the above object, the wall connecting anchor of the present invention is an anchor that is fixed to the frame of a wooden building and can be reused even after fixing. A plate that is fixed to an arbitrary position on the skeleton by bolting, a support tube that is welded from the front or side of the plate toward the outer wall forming surface and that can be screwed to the scaffold wall connection end, and a scaffold wall connection. and a protective member that is attached to the support tube that is exposed after removal.

[Operation] The plate is fixed to the frame, and the scaffold wall connecting end is screwed to the support cylinder welded to the plate, so the scaffold and the frame are connected and fixed, and the scaffold is stabilized.

Additionally, after construction is complete, remove the scaffolding wall connections, expose the front part of the support tube to the outside wall, and leave it covered with protective material in preparation for reuse when re-assembling scaffolding, etc. I can do it.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view showing the state in which the wall connecting anchor of the present invention is used.
2 is a wall connecting anchor, 3 is a wall connecting member, and 4 is a scaffolding material.

The wall connecting anchor 2 is a plate 5 that is fixed to the pillar 1, which is the frame part, with bolts or nails 6.
and a polygonal or cylindrical support cylinder 7 welded to the plate 5. A female threaded portion 8 is formed inside the support tube 7 as shown in FIG. On the other hand, the wall joint 3 that connects the scaffolding material 4 and the main body part is a turnbuckle, and the main body 3a
A clamper 3c for gripping the scaffolding material 4 is attached to the tip of the screw rod 3b screwed to one end,
A male threaded rod 3d is attached to the other end to be screwed into the female threaded portion 8 of the support tube.

In this way, the scaffolding material 4 is fixed to the pillars 1 of the frame section by the anchors 2 via the turnbuckle-type wall connections 3. Since the support tube 7 of the wall connecting anchor 2 and the wall connecting male screw rod 3d are screwed together, they do not loosen easily and the scaffolding is stabilized.

After the construction is completed using the scaffolding and constructing the base 9, mortar 10, etc. as shown in Figure 2, the scaffolding material 4 is dismantled, but the anchor 2 can be removed by simply turning the male screw rod 3d and removing the wall connection 3. Leave it fixed to pillar 1. The tip of the support tube 7 of the anchor 2 is made to protrude slightly from the outer wall, and is covered with a cap (protective member) 11 to prevent rainwater from entering.

If you leave the wall-connecting anchors 2 in the frame after the construction is completed, you can quickly screw together the wall-connecting male screw rods 3d when scaffolding is needed again, such as when re-forming a wall or roof. Therefore, the scaffolding material 4 can be assembled stably.

Although the embodiments of the present invention have been described above with reference to the drawings, the wall connecting anchor of the present invention is not limited to the illustrated example. For example, in the embodiment, the support tube 7 is welded from the side surface of the plate 5 toward the outer wall forming surface, but the support tube 7 may be welded to the front surface of the plate 5 as shown in FIG. Further, the support tube is not limited to a rectangular tube shape, but may have another shape such as a cylindrical shape.

[Effects of the invention] As mentioned above, the wall-joining anchor of the present invention can fix the scaffold to the frame without loosening during use by screwing the scaffold wall-joining end to the support tube. . Additionally, since there is no need to remove wall anchors when laying the base and installing mortar, the scaffolding can be firmly fixed to the frame and stabilized until construction is complete. Therefore, the workers can work safely and are not distracted by the scaffolding, so they can concentrate on their work and improve their work efficiency. In addition, since a protective member is attached to the support tube after the scaffold wall connections are removed, it is possible to reuse the anchors left in the frame during re-forming after construction is completed.
