Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a member for renovating an outer wall of a building. 2. Description of the Related Art Conventionally, a commercially available lightweight steel frame material has been used as an outer wall base material for repairing an outer wall of an existing building with a dry-type exterior material, and has a long trunk edge and an L-shape. The long body edge is provided with fixing holes at a predetermined pitch in advance, and the angle pieces are fixed to the existing wall at the same pitch, and the body edge is attached to this to form the base What to do. Met. On the other hand, if the existing wall is made of reinforced concrete in this series of operations, the anchor bolts for fixing the angle pieces may unfortunately hit the internal rebar, and in this case, the anchor bolts are shifted without stopping. However, the conventional fuselage had the disadvantage that the mounting holes had to be reworked and the construction was time-consuming. In order to solve the above-mentioned drawback, the present invention fixes the anchor bolts without shifting the position of the anchor bolts from a predetermined pitch without re-drilling the mounting holes on the body edge side. The task is to be able to do so. Accordingly, in the present invention, three continuous holes are provided by adding mounting holes to the body edge side at positions 20 mm to 80 mm apart from each other at a predetermined pitch in the front and rear by 20 mm to 80 mm. It is intended to solve the above problems. FIG. 1 is a schematic view showing a state of a renovation work of an outer wall using an outer wall base rim, which is an embodiment of the present invention. The fixing member is a so-called angle piece obtained by processing an equilateral angle steel, and the body green is made of the same equal angle angle steel. The existing walls are made of reinforced concrete and have been damaged and stained over many years. Since it is fully anticipated that the anchor bolt will hit the internal rebar, a plurality of mounting holes in the body edge are provided in advance near a predetermined pitch as shown in the figure. As a construction method, first, the fixing member is fixed in advance with an anchor bolt, and then the body edge is brought into contact with the fixing member and joined with a bolt or the like to form a base. Because the existing wall is made of reinforced concrete, unfortunately the anchor bolts may hit the reinforcing steel inside the concrete. In this case, the anchor bolt can be fixed without any trouble by once pulling out the anchor bolt, shifting the position in accordance with the fixing hole provided in advance in the vicinity, and rehitting. As described above, the outer wall base rim according to the present invention is provided with mounting holes before and after a predetermined pitch, so that even if the anchor bolt hits the internal rebar, the mounting hole is re-drilled again. It can be installed without any trouble, and there is an effect that work is not delayed.

Claims (1)

(57) [Claims for utility model registration] In the exterior wall renovation work, in which a new exterior material is constructed on the exterior wall of an existing building, an L-shaped cross section is attached to one side of the equilateral mountain steel, which is the base hull used. The mounting holes for the vertical side of the angle piece fixing member are provided at a predetermined pitch in advance, and holes are provided at positions 20 mm to 80 mm apart before and after the pitch, so that three mounting holes are provided for each pitch. The outer wall base rim characterized by being lined up.
