Description

  The present invention relates to a drilling jig for a lightweight cellular concrete (ALC) corner panel disposed at a corner in a building wall formed by a lightweight cellular concrete (ALC) panel.

  When building a wall body with an ALC panel in a building including medium- and low-rise houses, an ALC corner panel made of the same material as that of the panel is arranged at the corner to form the wall body. This is generally done (see FIG. 4).

  For example, in Patent Document 1, a hole-like member of such an ALC corner panel is perforated, a rod-shaped member having a flange is inserted into the hole and fixed, and the housing and the flange are fixed directly or indirectly. Discloses an ALC corner panel mounting structure in which a corner panel is mounted on a housing.

  Further, Patent Document 2 discloses a drilling device for an ALC corner panel, which is provided with a conveying means such as a conveyor and a punching means in which a drill for drilling is arranged for the purpose of accurately and easily performing the above-described drilling. It is disclosed.

Japanese Patent Laid-Open No. 10-338981 JP 2001-162615 A

  According to the apparatus described in Patent Document 2, it is possible to accurately perforate the ALC corner panel before carrying it into the construction site. However, especially in the construction of relatively small low-rise houses, it may be necessary to carry out the above drilling work manually in the construction site after carrying the ALC panel, which is a precast panel, into the construction site. Many.

  In manual drilling using a drill or the like for an ALC corner panel, the drilling position and direction are likely to vary. For example, when the vertical hole 51 shown in FIG. 3 is not formed perpendicular to the facet, the anchor inserted into the ALC corner panel 5 is inclined. Further, when the horizontal holes 52 and 53 are not formed perpendicular to the abdominal surface, that is, perpendicular to the vertical hole, the bolt inserted from the horizontal hole cannot be screwed into the anchor in the vertical hole 51. . When such a problem occurs, the opening diameters of the vertical holes 51 and the horizontal holes 52 must be widened, and in this case, the strength of the ALC panel mounting portion may be reduced.

  When it is necessary to manually drill the ALC corner panel in a construction site, etc., this drilling is performed manually without using a drilling device as disclosed in Patent Document 2. There has been a demand for means that can be performed with high accuracy while being possible.

  An object of this invention is to provide the means which can perform the drilling | piercing operation | work to the lightweight cellular concrete (ALC) corner panel in a construction site with high precision by manual operation.
