Description

  The present invention relates to a renovation metal fitting having a slate-spared structure.

  In factories and the like, relatively inexpensive slate-fired structures have been used for roofs and outer walls. As conventional slate, asbestos slate using asbestos and cement as a raw material is common. When such a slate-rolled structure becomes obsolete, asbestos is harmful to the human body, so that the outside of the slate-fired structure is covered with a steel plate or the like without breaking the slate.

  Patent Document 1 discloses a repair metal fitting used for such an application. The repair metal fitting shown in the above-mentioned document 1 is modified by utilizing the fact that the tip of the hook bolt for fixing the existing slate thatched roof to the structural material of the main building protrudes from the outer surface of the slate thatched roof. Pass the bolt insertion hole of the locking tool provided on the bracket through the bolt tip, and lock the repair piece by locking the locking piece formed in the bolt insertion hole to the screw thread on the outer periphery of the bolt tip. It is mounted on a thatched roof. A plurality of refurbishment brackets are installed at intervals, and hanging lumber is spanned between the refurbishment brackets, and a new roofing material is hung and fixed so as to cover the slate thatched roof.

  By the way, as described above, the above-mentioned conventional repair metal fittings are mounted through the bolt insertion holes at the tip of the hook bolt protruding from the outer surface of the slate thatched roof, but this tip has been used for many years. As a result, it is rusted, chipped, or brittle, so that there is a problem that it takes time for mounting and it is difficult to mount securely.

  Therefore, the present invention solves such a problem, and renovates the building slate-fired structure that is quickly and surely mounted using the shaft part excluding the tip of the hook bolt used in the building slate-fired structure. It aims at providing metal fittings.

  In order to achieve the above object, in the first device, a repair metal fitting (1) used for repairing a building slate-fired structure in which a slate plate (2) is fixed to a building structure material (5) by a bolt member (3). A flat substrate (11), a striking portion (12) bent at one side edge of the substrate (11), and the other side edge of the substrate (11) opposite to the one side edge. And a notch groove (13) having a width slightly smaller than the shaft diameter of the bolt member (3), formed in the direction of one side edge.

  In this first device, the open end of the notch groove of the repair fitting is made to coincide with the shaft portion excluding the tip of the bolt member from the lateral direction, and the notch groove is hit by hitting the striking portion of the repair fitting in this state. The shaft portion of the bolt member is relatively press-fitted inside. As a result, the repair metal fitting is reliably and quickly attached to the shaft portion of the bolt member. In this case, it is preferable that the portion where the repair metal fitting is mounted is a portion closer to the bolt head than the nut mounted on the shaft portion. This is because rust is hardly generated even after many years of use. Further, according to the present invention, it is possible to easily manufacture a repair metal fitting by simply forming a beating portion on one side edge of the flat substrate and forming a notch groove on the substrate surface from the other side edge. Such a repair metal fitting is lightweight, and the workability is good because the operator can carry it in a compact state in which a plurality of repair metal fittings are stacked.

  In the second device, the striking portion (12) is formed by bending one side edge of the substrate (11) into a substantially U shape, and the outer surface of the standing wall (121) is used as a striking surface (121a). .

  According to the second device, the rigidity of the substrate, that is, the entire repair metal fitting is improved by the striking portion bent and formed in a substantially U shape.

  The reference numerals in the parentheses indicate the correspondence with specific means described in the embodiments described later.

  As described above, according to the modified metal fittings of the building slate-fired structure of the present invention, the modified metal fittings can be quickly and reliably attached to the shaft portion excluding the tip of the hook bolt used in the building slate-fired structure, As a result, the renovation work for installing a new roofing material or outer wall material covering the existing slate-fired structure can be efficiently performed.

It is a top view of the repair metal fitting which shows one Embodiment of this invention. It is sectional drawing of the repair metal fitting along the II-II line | wire of FIG. It is a perspective view which shows mounting | wearing of the repair metal fitting to the front-end | tip shaft part of a hook bolt. It is sectional drawing of the building slate-sparing structure in the state which attached the repair metal fitting to the hook bolt. It is a perspective view of the hook bolt with which the repair metal fitting was mounted and fixed. It is a perspective view of the state which fixed the hanging lumber to the repair metal fitting.

  FIG. 1 shows a plan view of the modified metal fitting, and FIG. 2 shows a cross-sectional view thereof. The repair metal fitting 1 includes a rectangular plate-like substrate 11, and a striking portion 12 is bent along one side edge of the substrate 11. An example of the thickness of the substrate 11 is 1.2 mm for the roof and 0.5 mm for the outer wall. The striking portion 12 is formed by bending one side edge of the substrate 11 into a substantially U-shaped cross section having a standing wall 121 and a lateral wall 122, and the outer surface of the standing wall 121 is a striking surface 121a. The striking portion 12 having a U-shaped cross section also exhibits an effect of increasing the rigidity of the substrate 11.

  A notch groove 13 is formed in the center on the other side edge of the substrate 11 opposite to the one side edge. The notch groove 13 has one end opened to the other side edge of the substrate 11 and the other end extending in a certain length toward the one side edge of the substrate 11. The notch groove 13 has a constant width d slightly smaller than the shaft diameter of a hook bolt described later, and the groove width is gradually increased outward at the open end.

  When repairing a slate-spared structure of a roof or an outer wall using such a modified bracket 1, the modified bracket 1 is attached to a hook bolt as a bolt member fixing a slate plate to a structural material of a building. Do. As shown in FIG. 3, for example, in this embodiment, the modified metal fitting 1 is laterally applied to the shaft portion excluding the tip portion 31 of the hook bolt 3 protruding on the outer surface of the peak portion of the slate plate 2 which is corrugated in this embodiment. By aligning the open end of the notch groove 13 and hitting the striking surface 121a of the repair fitting 1 with a metal hammer or the like in this state, the shaft part of the hook bolt 3 is relatively press-fitted into the notch groove 13. Do.

  As shown in FIG. 4, the shaft portion 33 of the hook bolt 3 to be relatively press-fitted is located between the washer 42 and the packing 43 on the bolt head 32 side below the nut 41 attached thereto. Is good. The shaft portion 33 below the nut 41 is often free from rust even after many years of use, so that a sufficient press-fitting strength can be obtained, and a relatively light striking force can be obtained due to the gap generated between the washer 42 and the packing 43. Thus, the shaft 33 can be easily press-fitted into the notch groove 13 of the repair fitting 1. In addition, in FIG. 4, the code | symbol 5 is the structural material of the building in which the hook bolt 3 is latched.

  In this way, as shown in FIG. 5, after mounting a plurality of repair fittings 1 at appropriate intervals on the shaft portion (FIG. 4) of the hook bolt 3 protruding from the peak portion of the corrugated slate plate 2, these are attached. For example, the hanging lumber 6 (FIG. 6) having a hat-shaped cross section is arranged so as to be connected, and this is fixed to the substrate surface 11 of each repair fitting 1 with a screw screw or the like. A plurality of hanging timbers 6 are provided in parallel on the structure of the slate thatched roof and the outer wall using the modified metal fittings 1, and then a new roofing material and outer wall material are hung on the hanging timber 6 so as to cover the slate thatching structure Hand it over and fix it with screw screws. In this embodiment, since the peak portion of the corrugated slate plate 2 having a slate-rolled structure is close to the back of the hanging wood 6 (see FIG. 4), external pressure is applied to a new roofing material or outer wall material covering the slate plate 2. Even when is applied, the hanging wood 6 is supported in contact with the back of the slate plate 2 and exhibits sufficient strength.

  Even if the position of the shaft portion 33 of each hook bolt 3 is slightly deviated from the straight line, the relative approaching amount of the shaft portion 33 into the notch groove 13 is adjusted by adjusting the striking force to the repair fitting 1. By doing so, the mounting position of the repair fitting 1 can be adjusted, so that the hanging lumber 6 can be fixed to a predetermined position of the substrate 11 of each repair fitting 1 (FIG. 1). Further, if the repair metal fitting 1 having a relatively thin plate thickness as compared with the roof is used on the outer wall of the slate roof, the straight state of the hanging lumber 6 is maintained by appropriately deforming the substrate 11 of the repair metal fitting 1. The appearance of the new outer wall material covering the slate plate 2 can be prevented from being deteriorated. Instead of fixing the hanging lumber 6 on the substrate 11, it may be fixed on the lateral wall 122 of the striking portion 12.
