Description

  The present invention relates to a method for reinforcing an outer wall panel for reinforcing an outer wall panel used in a structure such as a multi-story parking lot.

  An outer wall panel made of a slate material or the like is used for an outer wall of a structure such as a multi-level parking lot. Between the adjacent outer wall panels (joint), a caulking material for waterproofing was filled, and the outer wall panel was fixed to the body edge fixed to the steel frame from the outside by screws.

  For example, when about 10 years have passed since the construction, the caulking material filled in the joints deteriorates over time, and the caulking material is cracked and the like, resulting in a decrease in waterproofness. Due to the deterioration of the waterproof property, water penetrates into the structure from between the outer wall panels, causing corrosion on the trunk edge. If the trunk edge is corroded, the screws for fixing the outer wall panel will not work, the outer wall panel may be separated from the trunk edge, and the outer wall panel may fall due to strong wind.

  Therefore, it is necessary to reinforce the outer wall panel in order to prevent the outer wall panel from falling against the structure in which the body edge is corroded.

  Conventionally, a temporary scaffold was built on the entire outer surface of the structure, the caulking material was repaired, the reinforcing material was applied to the corroded trunk edge, the screws were re-applied, and then the outer wall panel was repainted. We were reinforcing. However, it took a lot of money to set up a temporary scaffolding, and the construction was long.

The reinforcing member 1 is, for example, an iron plate, and extends in the left-right direction (width direction, horizontal direction) from the storage portion 2 formed inside by being bent in a convex shape and the edge of the storage portion 2. The protruding flange portions 3 and 3 are formed.

  The width of the storage portion 2 is wider than the width of a trunk edge 4 (see FIG. 3) described later. The depth of the storage portion 2, that is, the height from the lower surface of the flange portion 3 to the bottom surface of the storage portion 2 is equal to or substantially equal to the height of the trunk edge 4.

  The flange portions 3 and 3 are provided with through holes 5 at predetermined locations, for example, at two locations. A fixing member 6 to be described later is inserted into the through hole 5.

  2A and 2B show the fixing member 6, respectively. The fixing member 6 includes a shaft 8 having a screw portion 7 formed on the base end side, and a shaft attached to the tip of the shaft 8 (left side with respect to the sheet surface in FIGS. 2A and 2B). It consists of a stop piece 9.

  The locking piece 9 is rotatably provided via a pin 11 and has a groove (not shown) in which the shaft 8 can be accommodated. In the state where the shaft 8 is housed in the groove, as shown in FIG. 2A, the shaft 8 and the locking piece 9 are arranged on a substantially straight line, and the fixing member 6 has a rod shape.

  Further, the locking piece 9 is provided eccentrically with respect to the shaft 8, and when the fixing member 6 has a rod shape as shown in FIG. It is located on the tip side from the pin 11. Accordingly, when the locking piece 9 is freely rotated, as shown in FIG. 2B, the locking piece 9 rotates by its own weight, and the fixing member 6 becomes T-shaped.

  Next, the reinforcement of the outer wall panel using the reinforcing member 1 and the fixing member 6 will be described with reference to FIGS. In FIG. 3, the upper side with respect to the paper surface indicates the outside of the structure, and the lower side with respect to the paper surface indicates the inside of the structure. In FIG. 5, the right side with respect to the paper surface indicates the outside of the structure, and the left side with respect to the paper surface indicates the inside of the structure.

  The trunk edge 4 extends in the vertical direction and is fixed to a structure, for example, a wall steel frame (not shown) of a multilevel parking lot. An outer wall panel 12 made of the slate material or the like is fixed to the body edge 4 with screws 13 at predetermined positions, for example, two places on each of the left and right sides. A joint 14 is formed between the adjacent outer wall panels 12 and 12.

  A convex aluminum joiner 15 is fitted into the joint 14 from the inside over the entire length of the joint 14. The joint 14 is filled with a caulking material 16 from the outside.

  Corrosion of the trunk edge 4 occurs particularly at a position where the joint 14a extending in the vertical direction intersects with the joint 14b extending in the left-right direction, and in the vicinity thereof, at and around the insertion position of the screw 13. easy. Therefore, in the present embodiment, the reinforcing member 1 is attached with the intersecting position and the peripheral portion of the joint 14a extending in the vertical direction and the joint 14b extending in the left-right direction as reinforcing positions. . Hereinafter, a method for attaching the reinforcing member 1 will be described.

  First, the reinforcing member 1 is placed on the trunk edge 4 so that the trunk edge 4 is accommodated in the accommodating portion 2 at the reinforcing position. Next, a hole is drilled in the outer wall panel 12 from the inside through the through hole 5 by a drill.

  After drilling the hole in the outer wall panel 12, the fixing member 6 is inserted into the through hole 5 and the hole in the outer wall panel 12 in a state where the fixing member 6 is in a rod shape as shown in FIG. insert. Note that, when the state shown in FIG. 2A is turned upside down, the rod shape is maintained by the action of gravity, so that the work becomes easy.

  After inserting the fixing member 6 until the locking piece 9 is completely exposed to the outside of the outer wall panel 12, the shaft 8 is rotated to the state shown in FIG. 9 rotates by its own weight, and the fixing member 6 becomes T-shaped as shown in FIG.

  In a state where the locking piece 9 rotated by its own weight is in contact with the outer wall panel 12, a nut 17 is screwed onto the screw portion 7 and tightened with a required torque, so that the outer wall panel 12 becomes the flange portion. 3 and the locking piece 9 are clamped. At this time, since the depth of the storage portion 2 is equal to or substantially equal to the height of the trunk edge 4, the storage portion 2 and the trunk edge 4 are in close contact, and the trunk edge 4 is the reinforcing member. 1 and the outer wall panel 12 are inserted. Accordingly, the reinforcing member 1 reinforces the trunk edge 4 and the reinforcing member 1 itself is fixed to the outer wall panel 12. Further, the outer wall panel 12 is fixed to the trunk edge 4 via the reinforcing member 1.

  Therefore, by attaching the reinforcing member 1, the outer wall panel 12 and the trunk edge 4 are brought into close contact with each other, and the reinforcing member 1 supplements a portion where the strength of the trunk edge 4 is reduced, so that the outer wall panel 12 is reinforced.
