There is an official gazette. There, on the gate-shaped roof receiving frame fixed on the roof base material, the joining walls of adjacent folded roof materials are joined and supported, and a clip is press-fitted to this joint from above, and A long cap is press-fitted from above to join and fix the folded roof material.

[0003] Such a conventional type has a smaller load-bearing capacity and wind-proof strength than a work form in which the joints of the folded roof material are wound or bolted together. The application was limited. However, since the workability at the site is outstanding, it is being applied to a folded roof using a large folded roof material such as a gymnasium or a large warehouse.

[0004]

The rising dimension of a conventional folded roofing material for a light load is only about 5 cm, but that of a large folded roofing material is as large as 12 to 16 cm. Therefore, simply increasing the size of the light load roof receiving frame does not provide sufficient strength, and the legs of the roof receiving frame are buckled and deformed when a large load such as snow is applied.
Increasing the thickness and width of the steel sheet can improve the structural strength of the frame to some extent, but in this case, the cost of the raw material increases and the processing cost increases.

[0005] The roof receiving frame includes a frame body fixed to the roof base material, and a locking metal attached to the upper side of the frame main body. In many cases, the locking metal is mounted on the upper side of the frame main body. It was fixed with rivets. In the roof receiving frame with the riveting fasteners,
Each time the specification dimensions, such as the cross-sectional shape and thickness of the joint of the folded roof material, or the thickness of the backed insulation, change, a dedicated roof receiving frame with a different shape of the locking bracket must be prepared separately However, the manufacturing cost of the entire roof receiving frame is high, and the management becomes complicated.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a roof receiving frame for a large folded roof, which has a sufficient buckling strength without increasing material costs and processing costs. Another object of the present invention is to provide a roof receiving frame that can easily cope with changes in the cross-sectional shape and thickness of a joint portion of a folded roof material and can share a frame body.

[0011]

When each of the legs 8.8 is formed with the main leg 8a in the shape of a vault including the shoulder bulging wall 8d as a main portion, each leg 8.8 is formed.
, The buckling strength of the frame body 2 can be improved. The partial spherical shell-shaped inflatable wall 8d located on the upper part of the leg main wall 8a contributes to the enhancement of buckling and bending strength at the upper end of the leg main wall 8a, and the folded roof material 4

Just select the fastener 3 and the frame body 2
Can be shared.

In the roof receiving frame according to the fourth aspect, the leg portions 8.8 of the frame main body 2 are formed in a C-shaped cross section, as compared with a flat plate or a case where reinforcing ribs are additionally formed on a flat plate. This is because the second moment of area of No. 8 is made larger and the overall buckling strength is obtained accordingly. Since the processing range of the C-shaped cross section is limited to the upper and lower ranges of the two legs 8, 8, the bending between the base 7 and the legs 8 connected thereto can be easily performed. The reinforcing ribs 14 and 15 are provided on each leg 8.
In accordance with the enhancement of the buckling strength, the bending strength between the leg portion 8 and the base portion 7 or the shoulder portion 10 is ensured. Also in this case, since the locking fitting 3 is fastened and fixed to the upper side 9 of the frame main body 2 with the bolts 22 and the nuts 23, the locking fitting 3 can be easily attached to and detached from the frame main body 2.

[0014]

According to the present invention, the main legs 8a of the frame body 2 that are easily buckled are formed with the main legs 8a in the shape of a canopy, or the two legs 8.8 are formed in a C-shaped cross section. By increasing the second moment of area, sufficient buckling strength is obtained. Therefore, compared to the case where the conventional roof receiving frame is simply scaled up, a roof receiving frame for a large folded roof that can withstand a heavy load with a thinner material can be configured, and the material cost and processing cost increase. Therefore, a large roof receiving frame can be manufactured at low cost.

Since the latch 3 is removably fastened and fixed to the upper side 9 of the frame body 2 by using bolts 22 and nuts 23, the roof supports 4 corresponding to various folded roof materials 4 having different shapes and structures. The frame can be easily configured, and even after fixing the base part 7 to the roof base material 1 at the construction site as well as at the factory, the specifications of the folded roof material 4 can be changed simply by replacing the locking metal 3 Can respond quickly.

According to the roof receiving frame provided with the rotation preventing portion 20a and the locking portion 9a which are in contact with each other on the seat plate 18 of the locking metal member 3 and the upper side portion 9 of the frame body 2, respectively. Since the metal fittings 3 can be fastened and fixed in a state where the metal fittings 3 are positioned in an appropriate posture, the fitting 3 can be efficiently attached at a factory or a construction site. Detent part 20
Since the a and the locking portions 9a function as reinforcing members for the seat plate 18 and the upper side portion 9, respectively, the rigidity of the roof receiving frame can be increased in addition to the strength of the legs 8.8, and the robustness thereof can be improved.

Reinforcing ribs 14 and 15 are provided at the bent portions between the base portions 7 and the leg portions 8 and between the shoulder portions 10 and the leg portions 8, respectively, so that the structural strength at the bent portions is enhanced. Thus, the strength of the frame body 2 can be further improved. When a large load acts on the folded roof material 4 due to snow accumulation or the like, the shoulder 26 of the folded roof material 4 can be received by the shoulder inflated wall 8d and the shoulder portion 10 of the frame body 2, so that the folded roof material 4 Can be stably supported by the sturdy frame body 2. Thereby, it is possible to reliably prevent the folded roof material 4 from being deformed and the joint 25 from being disconnected.
