Description

  The present invention relates to a mounting structure for a scaffolding connection for an outer wall made of an ALC panel.

  When constructing an outer wall of a building using an ALC panel, an external scaffold is generally used around the building. When connecting such a scaffold to a building frame, a single pipe or the like is used to attach the scaffold beforehand. However, as the construction of the wall progresses, these single pipes are removed, the hardware for anchoring the scaffold is attached to the building frame, and the anchor member for anchoring the anchor is screwed onto the bracket using the anchor for anchoring. Must be connected to the building frame.

  Conventionally, for example, as shown in FIG. 3, a long nut (4) is welded to a base steel material such as an L-shaped angle (3) for attaching an ALC panel (1) to a building frame (2), and a scaffolding connection (7) The anchor link (7) is attached by screwing the male screw (9) of the anchor portion (8) of the anchor portion (8) onto the long nut (4) or the like.

  In addition, in addition to the dedicated hardware (10) for connecting the scaffolds shown in FIG. 4, there is a case where the scaffolding is connected to the building frame using dedicated members shown in Patent Document 1 and Patent Document 2.

  Some of these long nuts and dedicated members are present at the horizontal joints of the upper and lower ALC panels, extending from the indoor side of the ALC panel to the outdoor side during or after the construction. When the movement of the ALC panel is not assumed as in the insertion muscle construction method, there is no problem even if they project to the outdoor side, but in recent years, the construction method that allows free movement of the ALC panel, such as the rocking construction method. The long nut that protrudes and is fixed to the horizontal joint of the ALC panel obstructs the free movement of the ALC panel during construction or after construction, or the ALC panel is moved by the movement of the ALC panel. There is a problem of causing damage.

  Since the gap between the indoor side surface of the ALC panel and the base steel material such as an L-shaped angle is generally about 6 mm, as shown in FIG. 5, the hexagonal height is smaller than the gap so as to fit in the gap. It is conceivable that the nut is welded to a base steel material such as an L-shaped angle, and the anchor portion connecting the scaffolding from the outdoor side of the outer wall is fixed to the hexagon nut. However, such a thin hex nut has a problem that there is a problem in safety because the fitting length between the anchor portion and the hex nut is short and strength cannot be expected.

On the other hand, in Patent Document 3, a connecting bolt is attached to a beam using a through hole provided in advance on a vertical surface of a beam that is a building frame, and a scaffolding link is attached to a nut attached to the outdoor side of the connecting bolt. The connection is described. However, due to the mounting height, vertical joints between the ALC panels are passed, and in that case, there is a problem that it is necessary to make holes in the joints between the ALC panels.

  The anchor joint can be connected and fixed to the building frame by inserting the anchor portion of the scaffold joint into the through hole and screwing and fixing it to the nut.

  In this case, it is preferable to further include a nut welded to the outdoor side of the vertical surface of the base steel material and having a height smaller than the gap width between the ALC panel and the base steel material.

  In addition, the attachment structure of the scaffolding connection according to another aspect of the present invention includes an anchor part that is inserted into a horizontal joint part of the ALC panel and has an external thread part at the tip, and the ALC panel is attached to the building frame. A through hole is provided on the vertical surface of the base steel material to be attached to the ALC panel at the same level as the horizontal joint portion of the ALC panel, the male screw portion is inserted into the through hole, and the base steel member is inserted into the male screw portion. A nut is screwed from the inside, and a nut having a height smaller than the gap width between the ALC panel and the base steel material is screwed from the outdoor side of the base steel material, and both nuts are vertical surfaces of the base steel material. The scaffold tether is fixed to the base steel material by sandwiching. In such a case, it is preferable that both nuts are detachably fixed to the base steel material by spot welding or the like.

  The attachment structure of the scaffolding connection of the present invention does not hinder the free movement of the ALC panel such as rocking or sliding, so that the scaffolding connection is used without causing damage to the ALC panel during and after construction. External scaffolding can be connected to the building frame.

  An embodiment of the present invention will be described with reference to the drawings.

  The attachment structure of the scaffolding tie of the present invention has an L-shaped angle (3) which is a base steel material for attaching the ALC panel (1) to a beam (2) which is a building frame, and a vertical surface of the L-shaped angle (3). , A through hole (3a) provided at the same level as the horizontal joint of the ALC panel (1), communicated with the through hole (3a), and welded to the indoor side of the vertical surface of the L-shaped angle (3) Has a hex nut (5).

  The said through-hole (3a) should just be provided in the same level as the horizontal joint part of ALC panel (1), and is generally provided in base steel materials, such as L-shaped angle (3). The size of the through hole (3a) is such that the anchor portion (8) of the scaffolding joint (7) can be inserted and the hexagon nut (5) can be fixed around the through hole by welding. That's fine. Moreover, the hexagon nut (5) should just be provided with the height (length of an axial direction) which can fix a scaffolding joint (7) to base steel material reliably, and it is preferable that height is 10 mm or more. Long nuts and cap nuts may also be used.
