PURPOSE:To increase a strength by a method wherein a part of the lateral side of the L-shaped metallic fitting, attached to the rectangular wall of the outer box of a collector, is cut and raised to form a heat collecting panel supporting piece while the transversal side thereof is utilized as a metallic back plate fitting for a wire securing fitting. CONSTITUTION:The main body 6 of a metallic corner fitting 13 is formed by a longitudinal side 4 and the lateral side 5 while the upper half of the end of the lateral side 5 is cut and raised horizontally toward the inside thereof to form the heat collecting panel supporting piece 7. The supporting piece 7, the lateral side 5 and the longitudinal side 4 are bored with a bolt hole 9 for securing the heat collecting panel 8, the bolt hole 10 for securing the outer box of the collector and the bolt hole 11 for securing the wire securing fitting 12 respectively while the metallic corner fitting 13 is attached to a rectangular wall frame 2 to secure the heat collecting panel 8 and the wire securing fitting 12 rigidly. No obstructive structure is existing at the corner of the outer box, therefore, the longitudinal and lateral sides may be made into any desired size to increase the strength thereof and multiple functions may be provided to only one part. |
