Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roofing device having a folded plate structure, in particular, a long steel plate previously developed by the inventor, which is bent in the longitudinal direction into a chevron with a trapezoidal cross-section, and both hems are symmetrically bent. It extends horizontally to form an engaging edge, and both of these engaging edges are bent downward parallel to the oblique side of the trapezoidal chevron to form a diagonal piece to form a basic roof member. Two roof members are installed as a set of three in opposite directions at intervals, and one roof member is placed between the adjacent engaging edges and the diagonal piece of this roof member, and this is attached to both engaging edges. A block roof member is constructed by placing the diagonal pieces so as to cover them and combining the engaging edges and the diagonal pieces to form a pile of folded plate structures. After that, the adjacent engaging edges and diagonal pieces of each block roof member are placed so as to cover both engaging edges and diagonal pieces of the downward facing roof member, and each engaging edge and diagonal piece are applied. This relates to the improvement and creation of a roofing device in the form of a folded structure in which blocks are combined in tandem.The improvement is that in order to increase the strength against long roof members, roofing devices are installed at required intervals (standard 2m intervals) on block roof members. It incorporates a large number of reinforcing materials made of angle materials.

This reinforcing material is the lower part of the block roof member and is
A shape in which each trapezoidal chevron receiving frame of each roof member, each inner engaging edge, a receiving frame that simultaneously receives the adjacent interval, and a receiving frame that receives the outer engaging edge of the trapezoidal chevron are bent on a line, that is, It is constructed in a shape that matches the shape of the cross section of the two roof members excluding the diagonal pieces, and when this reinforcing material is attached to the block roof member, bolts are installed at positions that match the through holes, and the through holes are The roof members and reinforcing members are tightened with bolts, and the reinforcing members between adjacent blocks are connected with connecting rods before the final installation process of the roof members, and after the roof members are installed. It is what it is.

Therefore, since each block roof member is reinforced with a large number of reinforcing materials in the longitudinal direction, its strength is further increased in terms of structural mechanics. can be implemented.

In the present invention, a long steel plate is bent into a trapezoidal chevron cross section, and both skirts are symmetrically extended horizontally to form an engaging edge.
The basic roof member is constructed by bending both engaging edges downward parallel to the oblique sides of the trapezoidal chevron to form a diagonal piece. It cannot be used as a roof, but by bending the diagonal pieces downward parallel to the oblique sides of the trapezoidal chevron, it is possible to assemble a block roof member that forms a single pile of folded plate structures as a set of three pieces. Moreover, by assembling such a block, a long steel plate is bent into a trapezoidal chevron shape as in the past, and both skirts are symmetrically extended horizontally to form an engaging edge, and this engaging edge end is bent upward. Unlike roofing that is done by overlapping two-dimensional roofing, such as roofing with bent and slanted roof members, the depth of the mountain is doubled and the pitch of the mountain is also larger, so it is possible to create a large roof. As a result, the joints of the roof members are located in the middle of the mountain, unlike the conventional joints where the joints are at the bottom of the valley, reducing the risk of rain leaks and water leaks due to melting snow in snowy regions. All of that has disappeared.

In addition, as mentioned above, since the block roof member is made up of a set of three basic roof members and forms one pile of the folded plate structure, it is not only superior in strength to conventional products, but also
Furthermore, the engagement edge of the inverted roof member located below the block roof member and the reinforcing member formed by bending it in a line as a receiving frame shaped to receive the adjacent interval part and both trapezoidal and chevron parts, etc., are used to make many holes in the longitudinal direction. Insert the reinforcing material bolts into the provided through holes and tighten them together with nuts.Furthermore, each block roof member is connected with its own reinforcing material by connecting rods, and this reinforcing material is inserted at intervals of 2 m along the length. Since it is attached in the same direction, the mechanical strength of the structure is further increased.

Furthermore, if vertical ribs are provided on both hypotenuses of a trapezoidal chevron to further increase its strength, it is possible to construct a large deck that requires almost no beams or supports even with a 60m span roof, making it ideal for gymnasiums, factories, etc. It is extremely practical for roofing.

In addition, the strength of the block roofing material that forms one pile of the folded plate structure is further increased by reinforcing materials as described above, so if one block roofing material is installed during roofing work, it will become necessary for the next block roofing material. Because it can be used as a scaffold,
Unlike traditional roofing work, there is no need to assemble scaffolding, which has the advantage of streamlining the work.Also, since the reinforcing material can be hidden in the attic even if it falls, it has a good appearance. In addition, there is no risk of corrosion, and furthermore,
This reinforcing material can also be used as is for attaching lighting equipment.
