A hanger mounting structure that allows quick and strong installation, and also allows for easy confirmation of the position of the locking hole even when the roofing material is laid on a metal support material, and has good installation workability. Regarding.

[Prior Art and Problems] The applicant has already developed and implemented various types of horizontal roofing enclosures such as roofs or walls, but the hangers to which the horizontal construction boards are attached are made using drill screws, rivets, bolts, etc. Generally, they were attached using fasteners such as nuts. The hangers must be attached to each metal support material (metal taruki) in the longitudinal direction of the long horizontal building boards, and depending on the construction site, there may be an extremely large number of them, making construction cumbersome. In addition, the strength of the horizontal roofing enclosure against negative pressure (wind pressure) is greatly influenced by the strength of the hanger attachment, so the hanger must be firmly attached. Furthermore, as shown in Fig. 10, roofing material b is generally laid on top of the heat insulating material and metal support material a, which is the base of the horizontal construction board, but in this case, , its metal support a
If only the locking hole c is provided in the roofing material B, the position of the locking hole c cannot be seen from above after the roofing material b is laid, and the locking hole c cannot be seen from above using the pitch fitting d.
I was checking the pitch. In this case, only one piece of roofing material b can be laid in the direction above the water, which is extremely inefficient, and although not shown, it is the same material as the metal support material a, or it is made of the same material as the metal support material a. Pitch scales of the same length and with marks placed at the locking hole positions were used, but since they are long, they are cumbersome to carry and handle, and have the disadvantage of significantly reducing construction efficiency. It was hot.

[Means to solve the problem]

Therefore, as a result of intensive research to eliminate the above-mentioned drawbacks, the inventor has developed the present invention by providing a pair of elastic locking pieces on the lower side of the bottom attachment part of the hanger.
The locking piece is formed from a hanging portion and a folded edge, and a plurality of pairs of locking holes are bored at predetermined intervals in the longitudinal direction of the top surface of the metal support, and the inner edge of the pair of locking holes is is raised in an inclined shape to form an inclined projecting piece, and the pair of locking pieces of the hanger are inserted into the pair of locking holes of the metal support, and the bottom mounting part and the tip of the folded edge are connected to each other. By clamping the top surface and fixing the hanger to the metal support, it is easy to attach the hanger to the metal support by simply inserting and driving without using any fasteners. In addition, it can be installed quickly and firmly, and furthermore, even when the roofing material is laid on a metal support material, the position of the locking hole can be easily confirmed, which improves installation workability. It has solved its shortcomings and achieved its purpose.

b, 3b, and the top surface 4 of the metal support member B
A plurality of pairs of locking holes 5, 5 are bored at predetermined intervals in the longitudinal direction, and the inner edges of the pair of locking holes 5, 5 of the metal support member B are raised in an inclined shape to form an inclined protrusion 6. ，
6, insert the pair of locking pieces 3, 3 of the hanger A into the pair of locking holes 5, 5 of the metal support member B, and insert the pair of locking pieces 3, 3 of the hanger A into the ends of the bottom mounting portion 2 and the folded edge 3b. By clamping the top surface 4 and fixing the hanger A to the metal support B, firstly, the hanger A can be attached to the metal support B without using any fasteners. It can be easily and quickly installed by simply inserting and pouring.Secondly, it can be installed firmly.Thirdly, even when the roofing material 11 is laid on the metal support material B, the locking holes 5, 5 can be easily and quickly installed. This has the effect of making it easier to confirm the position of the parts and improving installation workability.

To explain this effect in detail, first, when attaching the hanger A to the metal support B, the pair of locking pieces 3, 3 of the hanger A are inserted into the pair of locking holes 5, 5 of the metal support B. 4, the locking piece 3 consisting of the hanging portion 3a and the folded edge 3b narrows against elasticity, and the inclined projections on both sides of the locking holes 5, 5 tighten. 6, 6 are driven with a hammer or the like, and at the same time, the folded edges 3b, 3b are completely inserted, and immediately after the insertion is completed, the folded edges 3b are expanded to the old position, and the folded edges 3b, 3b are completely inserted. The top surface 4 of the metal support member B is sandwiched between the upper end and the lower surface of the bottom mounting portion 2, and the ends of the inclined protrusions 6, 6 are hammered with a hammer or the like to form the inclined protrusions. The hanging portions 3a of the locking pieces 3, 3 at the ends of the pieces 6, 6,
3a is pressed and held in a riveting state, and the hanger A is firmly attached to the metal support member B. No fastening devices such as nuts are required at all, and the attachment can be made extremely simple. Therefore, it is necessary to attach a hanger A to each metal support member B in the longitudinal direction of the horizontal building board 7, which is longer than before, and depending on the construction site, the hanger A may be
requires extremely large quantities, but
By using the method of the present invention, the installation of the hanger A becomes simple and quick, the construction efficiency of the horizontal roofing enclosure is dramatically improved, and parts such as fasteners are not required.
These functions work synergistically, and there is an advantage that the horizontal roofing enclosure can be provided at a low price.

Moreover, the locking piece 3 has a hanging portion 3a and a folded edge 3.
b, and after completing the installation of the hanger A, the folded edge 3
b, the upper end, and the lower surface of the bottom mounting portion 2 to sandwich the top surface 4 of the metal support member B, and the locking piece 3 is fixed by driving the slanted protruding piece 6 with a rivet. Therefore, even if negative pressure (wind pressure) or the like is applied, it is possible to attach the hanger A extremely firmly.

Furthermore, in the present invention, since the slanted protrusions 6, 6 protrude upward from the locking holes 5, 5, even if the roofing material 11 is laid, the slanted protrusions 6, 6, as shown in FIG. At this point, the roofing material 11 becomes slightly bulged, and the positions of the locking holes 5 and 5 can be visually seen, and the hanger A can be attached very easily.
This has the great effect of doubling the installation efficiency. Therefore, as shown in FIG.
If roofing material b is laid on top and only the locking hole c is provided in the metal support material a, the position of the locking hole c cannot be visually seen from above after roofing material b is laid. During installation, check the pitch of the locking hole c using the pitch fitting d.
In this case, only one piece of roofing material b can be laid in the direction above the water, which is extremely inefficient, or the locking hole is made of the same material or the same length as the metal support material a. Using pitch scales with marks on their positions had the disadvantage of being cumbersome to carry and handle due to their long length, and resulting in a significant drop in construction efficiency.However, the present invention eliminates these problems. All deficiencies can be resolved.

As described above, in the present invention, the roofing material 11
Even if it is laid down, there is an advantage that the installation workability, strength, etc. of the hanger A can be extremely improved.
