The small protrusions 17 and 17 for reinforcement which straddle them are provided in the. As is apparent from FIG. 2, the frame member 1 is a metal frame body 1A whose entire surface is coated with a synthetic resin, and a synthetic resin coating layer is shown by reference numeral 1B.

The synthetic resin that covers the surface of the metal frame body 1A includes vinyl chloride resin and nylon resin.
The resin coating thickness is preferably 0.4 mm or more.

The frame members 1 are used as one pair facing each other symmetrically.

Next, referring to FIG. 2, a case will be described in which the outer roof 4 is heat-insulated on the inner roof 2 using the frame F composed of the pair of frame members 1, 1 described above.

A color steel plate or a galvanized steel plate is used for the roof plate 21 of the inner roof 2, and the tops of the mountain-shaped portions between the ends of the roof plate 21 are fixed to the base material M such as a beam or a purlin material. Suspended 23 mounted on folded roof roof frame 22
The fastener coupling portion 25 has a cylindrical head portion 25a and a flat neck portion 25b.

The pair of frame members 1, 1 are arranged so as to face each other symmetrically and are arranged on both sides sandwiching the neck portion 25b of the above-mentioned fastening coupling portion 25, and the frame members 1, 1 arranged as such.
The plate-shaped leg portion 51 of the suspension 5 is sandwiched between the rising portions 11 and 11 of the suspension 5, and the bolt insertion hole 53 formed in the leg portion 51 and the two bolt insertion holes 15 of the rising portions 11 and 11 described above. , 16 of the upper bolt insertion holes are aligned,
A bolt 61 is inserted into each of 53, 15, 15 and the bolt
The nut 62 is screwed into the 61. The suspension 5 is attached to the rising portions 11, 11 by tightening the bolt 61 and the nut 62. In addition, the bolt 61A is also inserted into the bolt insertion holes 16 and 16 on the lower side.
Nut 61B is screwed into the
The neck portion 25b of the fastener coupling portion 25 is clamped by the clamping portions 13 and 13 of the pair of frame members 1 and 1 by the clamping force with the.
The lower bolt 61A and the nut 61B are the frame member 1,
It is not indispensable because it can be omitted if the rising portions 11, 11 of 1 are short. In this state, frame members 1,1
The covering portions 12, 12 cover the upper surface of the head portion 25a of the fastening coupling portion 25. In this case, the posture of the frame F is more stable if the cover portions 12, 12 are engaged with the head portion 25a from above, but this need not always be the case, and the cover portion 12 is simply used. , 12 may cover only the head 25a. The upper ends of the protruding portions 13c, 13c of the holding portions 13, 13 are opposed to the lower surface of the head portion 25a of the fastening coupling portion 25. With this configuration, the roof plate 41 of the outer roof 4 described later
Even if the frame F is pulled upward as in the case where the frame F receives an upward wind pressure, the projecting portion 1 of the holding portions 13, 13
A situation in which the frame F is lifted up by the 3c and 13c being caught on the lower surface of the head portion 25a of the fastening coupling portion 25 is prevented.

In particular, when the outer roof 4 receives a strong wind pressure from diagonally above, the upper end of the projecting portion 13c of the one frame member 1 is located at the corner entry corner where the neck portion 25b of the lower surface of the head portion 25a of the fastener coupling portion 25 intersects. At the abutment, due to this abutment, the swelling portion 13a, the return portion 13b, and the holding portion 13 formed in the protruding portion 13c with a large bending stiffness and having a groove shape in cross section do not easily deform and sufficiently resist the wind pressure load. Frame F is head 25a
You can prevent it from leaning around.

And the roof plate of the outer roof 4 consisting of three mountains on its head 52
The tops of the chevron parts between the ends of 41 are fastened together. The top of the mountain portion of the middle portion of the roof plate 41 may be fastened and coupled to the tubular portion 52. A folded plate-shaped color steel plate is used for the roof plate 41 of the outer roof 4, and therefore, the fastening connection portion 54 thereof has a cylindrical head portion 54a and a flat neck portion 54b. Further, the support portions 14, 14 of the frame members 1, 1 correspond to the shoulder portions 42, 42 of the roof plate 41 adjacent to the fastening coupling portion 54, and the support portion 1
The shoulders 42, 42 are supported by 4, 14. In addition,
Although there is no inconvenience if the shoulder portions 42, 42 are lifted from the support portions 14, 14, the shoulder portions 42, 42 are not supported.
If it is in a state of supporting it by hitting, it will not only reliably maintain the coupling state of the fastener coupling portion 54, but also the roof plate.
The connection state between 41 and the suspension 5 becomes stable.

In FIG. 2, reference numeral 26 denotes a roof support hood 22 and a hanger 23.

According to the roof structure described with reference to FIG. 2, the synthetic resin coating layer 1B of the frame members 1 and 1 is interposed between the inner roof 2 and the outer roof 4 and they are not connected by a metal member. It becomes difficult for heat to be transferred between the outer roof 2 and the outer roof 4, and a heat insulating effect is exhibited. Further, the space S between the inner roof 2 and the outer roof 4 also exhibits a heat insulating action, but if a heat insulating material is loaded in the space S, the heat insulating action is further improved.

[Advantage of the Invention] Since the roof support frame of the invention of the first aspect has a structure which itself exhibits a heat insulating function, it does not use a separate component such as a block made of synthetic resin, but an inner roof and an outer roof. There is an effect that it becomes possible to insulate and construct.

In addition, the sandwiching part is formed with a groove shape in cross section that is difficult to deform at the bulging part, the return part and the projecting part, and the upper end of the projecting part is opposed to the lower surface of the head part of the fastening coupling part of the inner roof. Even when the roof receives a strong wind pressure obliquely from above, the frame does not tilt around the head and the outer roof can be supported stably and strongly at all times.

According to the invention of the second claim, since the frame and the bolt and the nut exhibiting the cross-sectional function are used only for the heat insulation of the inner roof and the outer roof, the construction is more difficult than the conventional construction. Not only is it simple, but the number of parts is drastically reduced, and the size and weight of the structure for supporting the outer roof can be reduced. At the same time, the cost can be reduced easily. .

Also, the bolt heads and nuts are pressed against the synthetic resin coating layer on the surface of the frame body, so that the locking effect can be achieved without the need to use washers, and the synthetic resin coating layer on the surface of the frame body has an inner roof. It is easy to adapt to the surface of the fastening joint part of the, and to the surface of the leg part of the suspension of the outer roof, and it can be closely polymerized with them without gaps, and a strong pressure-contact clamping state without rattling can be maintained for a long time. Furthermore, the fastening connection portion and the leg portion of the suspension can be pressed and clamped without scratches on their respective surfaces, which is also advantageous in preventing rust generated from these flaws.
