Description

[Detailed description of the invention] [Field of industrial application] This invention is a folded plate mounting structure, in particular, a folded plate mounting structure that can securely contact the panel support frame and the inverted L-shaped hanging plate. It is related to the disclosure of the structure.

[Prior art and its problems] The conventional installation of this type of folded plate was
Folded plates with grooves were attached to hanging plates fixed to the roofs, walls, etc. of buildings, and then tightened with bolts.

However, since such a method requires bolt holes, it has the disadvantage of preventing the intrusion of rainwater and the like.

In addition, there is a structure in which a hanger with a generally circular head section is closely fitted into the edge of the folded plate having grooves with an approximately circular cross section, and the hanger is tightened and fastened. Although it is easy to attach the folded plate to the hanger, it has the disadvantage that if a dimensional error occurs between the hanger and the folded plate, a gap will be created between the two, and they will easily come off due to a tensile force in the vertical direction.

[Means for Solving the Problems] This invention was devised in view of the above-mentioned inconveniences, and the trapezoidal peaks and the inverted trapezoidal valleys are continuous. In a folded plate structure consisting of a panel receiving frame 3 and a folded plate 1 having peaks and valleys of the same shape as this frame 3 and mounted on top of the frame 3, the frame 3 has a rising plate at its peak. A substantially inverted L-shaped hanger board 2 is erected, consisting of a portion 2b and a horizontal plate portion 2a that is bent laterally at the upper end of the rising plate portion 2b. The top part is open downward, and one side wall 1'c is connected to the other side wall 1'c.
A groove portion 1b having a width larger than the rising width of c is formed in the length direction of the peak by bending the folded plate 1 upward,
Lower end bent portion 1 of side walls 1c, 1'c of this groove 1b
d, 1'd and the top side end 1f of the mountain part,
The portion between the bent portions 1g and 1'g of the frame 3 is a plate portion that is in close contact with the top of the mountain portion of the frame 3, and the bottom width of the groove portion 1b is equal to the horizontal plate portion 2 of the hanging plate 2.
In addition, the rising width of one side wall 1c of the groove portion 1b is the rising width of the rising plate portion 2b of the suspender plate 2, and the rising width of the other side wall 1'c of the groove portion 1b is The width is set to be sufficient to extend diagonally from the tip of the horizontal plate portion 2a of the suspension plate 2 to reach the base of the rising plate portion 2b of the suspension plate 2, and the bottom surface of the groove portion 1b is The side wall 1'c of the groove portion 1b, which is in close contact with the upper surface of the horizontal plate portion 2a of the child plate 2 and has a large rising dimension, is bent toward the base of the rising plate portion 2b via the tip of the horizontal plate portion 2a of the suspender plate 2. This provides a folded plate mounting structure in which the lower end bent portion 1'd of the side wall 1'c having a large upright dimension is resiliently abutted against the base side of the hanging plate 2.

[Example] Hereinafter, details of a typical example of the folded plate mounting structure according to this invention will be explained with reference to the drawings. 2 is a hanging plate having a substantially inverted L-shaped cross section that fits into a groove 1b formed in the folded plate 1, and 3 is a panel receiving frame that serves as a beam frame to which the folded plate 1 is mounted. This is what is shown.

The top of the trapezoidal peak in the folded plate 1 is provided with a bent protrusion 1a that protrudes upward in the longitudinal direction of the peak. The groove portion 1b is configured toward the protrusion direction,
At the peaks located at both ends of the continuous peaks,
Engagement portions 1e and 1'e for connecting and fixing the folded plates 1 are provided.

The suspension plate 2 includes a rising plate portion 2b and a horizontal plate portion 2 bent laterally at the upper end of the rising plate portion 2b.
The lower end of the rising plate part 2b is fixed to a panel support frame 3 attached to a frame 5 such as a beam or rafter with bolts 4, nuts 4', etc. It is something that

The groove portion 1b is composed of a side wall 1c having the same size as the rising plate portion 2b of the hanger plate 2, and a side wall 1'c having a rising width longer than this side wall 1c. 1'c indicates bent portions 1 at both lower ends of the groove 1b when the hanging plate 2 is inserted into the groove 1b and folded toward the hanging plate 2 using a seamer or the like.
d, 1'd and the top side end 1f of the mountain part,
The folded plate 1 is adjusted in advance so that the folded portions 1g and 1'g with respect to the folded plate 1'f are at the same horizontal level via the suspension plate 2.

In this way, one side wall 1'c of the groove 1b in the folded plate 1 with the hanger plate 2 interposed therein is bent using a hand tool or a seamer, etc., and the folded plate 1 and the hanger plate 2 are integrally fixed. It is something to do.

[Function] Fig. 1 shows the state before the folded plate 1 is attached to the suspender plate 2 having a substantially inverted L-shaped cross section.
By operating this folded plate 1 so that the hanging plate 2 fits into the groove 1b and tightening the side wall 1'c of the groove 1b having a large rising dimension, the second
As shown in the figure, the folded plate 1 can be brought into close contact with the hanging plate 2 and the panel receiving frame 3.

At this time, the bent side wall 1'c is pushed upward by the stress of the restoring force directed toward the panel receiving frame 3, and with this pushing up force, the hanging plate enclosed in the groove 1b is 2
is pressed against the bottom of the groove 1b and the side wall 1c,
The folded plate 1 and the hanging plate 2 are crimped together.

[Effects of the invention] With such a structure, this invention corrects the inconveniences in the previous example, and improves the dimensions of the side wall 1'c and the rising plate 2b of the hanging plate 2 projected on the panel receiving frame 3. It is possible to easily accommodate changes in dimensions and errors by adjusting the folded dimensions of the side wall 1'c, thereby improving the fastening strength, and since there is no bolt hole, water infiltration is prevented. It can also be expected to improve durability.

Furthermore, the width of the horizontal plate portion 2a of the suspension plate 2 is approximately equal to the bottom width of the groove portion 1b, so that when the side wall 1'c is pushed toward the suspension plate 2, the wobbling of the folded plate 1 is prevented. In addition to effectively preventing the hanger plate 2 from falling down in cross-section L
The shape improves the grip of the hanging plate 2 on the folded plate 1, increases the engagement strength, and eliminates the fear that the folded plate 1 will separate from the hanging plate 2.
