Description

  The present invention is used to attach two upper and lower building outer wall materials to the base material of a building in a direction where the upper and lower sides are in contact with each other. It is excellent in load-bearing characteristics, has low material costs, and has excellent workability. It relates to mounting brackets.

As a metal fitting to be attached to the base material of a building in a direction in which two upper and lower building outer wall materials are faced up and down, the applicant has previously applied the fastening metal fitting and utility model registration No. 3153299 described in Utility Model Registration No. 3125473. The fastening bracket described in the Gazette was proposed.
Since these fasteners have a shallow depth in the front-rear direction, the space formed between the building outer wall material and the base material is narrow and air-permeable when the building outer wall material is attached to the front of the base material. It was inferior, and it was easy to become an environment where the base material and the inner wall of the building were easily corroded by moisture due to condensation.
For this reason, a mounting bracket (fastening bracket) having a deep depth in the front-rear direction has been proposed (Patent Documents 3 and 4). In these mounting brackets, since the horizontal portion 15 is deep in the front-rear direction, a part along both edge portions of the panel end facing portion 3 is partially attached to the left and right side plates in order to prevent warping and deformation due to load applied from above. It is reinforced by entering into a notch groove formed in the part.

Utility Model Registration No. 3125473 Utility Model Registration No. 3153299 JP 2008-261125 A JP 2009-138446 A

However, the above-described reinforcement by the mounting brackets described in Patent Documents 2 and 3 are both left and right edge portions such as the horizontal portion 15 and the panel end facing portion 3 in the notch grooves formed in the left and right side plate portions. Therefore, the horizontal portion 15 and the panel end facing portion 3 are supported by the notch groove with a short length.
For this reason, the horizontal part 15 and the panel edge facing part 3 cannot be supported deeply and stably in the lateral direction. When this notch groove is formed long, the strength of the left and right side plate portions decreases, so that only a short notch groove can be formed.
In order to reduce the material cost, if the plate thickness of the mounting bracket is to be suppressed to 1 mm or less, for example, about 0.8 mm, the lower edge portion of the notch groove, the support portion for the horizontal portion 15 and the panel end facing portion 3 Therefore, the horizontal portion 15 and the panel end facing portion 3 could not be sufficiently supported and reinforced.
In addition, the mounting brackets described in each of the above patent documents have dimensions that can be engaged and supported at desired locations on the upper edge of the building outer wall material. However, in the building outer wall material that is a ceramic product, When the craftsman raises the building exterior wall by hand, the mounting bracket is attached to the building exterior wall material. It may fall off from the upper edge, which has reduced workability.
