Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roof structure, and more particularly to a strong roof structure that has a simple structure and is easy to construct.

A typical example of the roof structure of a wooden house is one in which rafters and shedding boards are installed between the main building and the roofing material, and in the case of a concrete house, concrete is poured into the roof. be.

These roof structures are not easy to construct and install.
The inventor has focused on the problems of these conventional roof structures, and proposes this invention for the purpose of eliminating these problems. By fixing hangers and roof panels made of metal materials, especially light alloy materials, to the main building, a roof structure that is lightweight, robust, and easy to construct is provided.

The roof structure according to the present invention can be fully utilized in ordinary roof structures. On the other hand, because the space of houses is limited due to site constraints, so-called flat roofs, which are useful as balconies, drying clothes, or play areas, are being reconsidered.
There are many examples of houses adopting flat roofs.

However, when trying to adopt a flat roof for a house,
Construction of a flat roof is not easy because the above-mentioned roof construction method is applied. In addition, since loads are constantly applied to the roof surface of flat roofs, conventional construction methods require roof reinforcing materials to withstand this load, making construction even more difficult and sometimes causing damage due to partial loads. The conversion of the roof structure to a dome roof according to the present invention eliminates the above-mentioned drawbacks, and makes it possible to provide a roof structure that is easy to construct, robust, and has an excellent appearance.

Further, the roof structure according to the present invention has the advantage that it can be easily applied to a snow melting structure. A preferred embodiment of the invention will now be described.

A plurality of hangers 2 are spaced apart and fixed to the upper wall surface of a main building 1 arranged on the roof with wood screws or the like.

As shown in FIG. 2, the hanger 2 has a bottom wall 3 and a pair of side walls 4 that extend upwardly from both sides of the bottom wall, and extend inward from the upper part of the side wall 4. The stepped portion 5 is formed. The hanger 2 is formed from a metal plate, and is fixed to each main house 1 using wood screws or the like from the bottom wall 3 so that the centers of the opposite side walls 4 are aligned. FIG. 3 shows the roof panel 6.

A plurality of spaced apart grooves 8 are formed between the side edges T and 7' of the roof panel 6. The side wall 9 defining the groove 8 has a shape that follows the inner side of the side wall 4 of the hanger 2, and has a shape that follows the step portion 5 of the hanger 2.
It has a portion 10 that engages with. The opposite side wall 9 is the bottom wall 11'
This makes them integrally connected. The groove 8 of the roof panel and the center of the groove of the hanger are made to coincide with each other. By pushing the groove 8 of the roof panel into the inside of the hanger 2 from above the hanger 2 fixed to the main building, the hanger 2 and the roof panel 6 are
and can be detachably attached. The end groove formed in the left weave 7 of the roof panel 6 has a portion 10 on one side wall 9 that engages with the side wall step 5 of the hanger 2, and a portion 10 on the other side wall 1.
2 is made to stand upright at a position corresponding to the center of the groove of the hanger 2. An inwardly bent portion 13 is formed at the top of this upright side wall 12 . The end groove formed at the right side end 7' of the roof panel 6 is symmetrical with the end groove formed at the left side end 7. A bend 14 is formed that snaps into the bend. Adjacent roof panels 6 are joined together by snapping both side walls together. In this way, a plurality of roof panels can be easily connected. After the roof panel 6 is attached to the hanger 2, a cap 15 is detachably attached to the upper end of the groove 8 of the roof panel.

The cap 15 is attached to the stepped portion 10' of the groove side wall 9 of the roof panel 6.
The cap 15 has an engaging end 16 and a portion 18 that seats on the flat surface 17 of the side wall 9, and when the cap 15 is pushed into the groove 8, the end of the cap engages with the step of the groove and the groove is closed. 8.A sealing material 25 is provided at the contact part between the cap and the roof panel to prevent rainwater from flowing into the premises.When attaching the hanger 2 to the main building i, use a flat or round head. When using screws, it is recommended to pass a recess 18J for the screw head in the groove bottom wall 11 of the roof panel 6 in the longitudinal direction (fifth
(see figure).

For the purpose of preventing dew, that is, preventing fog, the roof panel 6
The inner surface of the hanger 2 may be molded, for example, from a metal plate to which a stripe prevention material such as a foamed polyethylene sheet is adhered. Furthermore, if heating fluid is to be passed through the lower part of the roof panel 6 in order to enhance the snow melting effect, a metal plate may be placed on top of the main building. Additionally, a rug such as artificial grass is placed on top of the roof panel to avoid direct transmission of solar heat to the roof panel. Using the cap 15, the handrail support 19 can be easily installed on the roof structure.

A base plate 20 is arranged so as to extend along the cap or into an adjacent cap, the plate 20 is fixed to the cap 15, and the channel material is attached with the plate 201 spaced apart. Fix the support 19 such as a handrail post to one channel material 2, and
Attach the lower end of the support body 23 to 2. The support body 23 is disposed obliquely with respect to the column 19, and its upper end is fixed to the column to reinforce the column. Thus, by installing handrails around the roof,
The roof surface can be used safely and maintains its aesthetic appearance. The upper ends of the struts are preferably connected by an integral rod. In the example shown in FIG. 8, the cap protrudes above the plane of the roof panel 6.

In this case, rainwater or the like that has entered the hanger 2 for some reason can be caused to flow back onto the roof panel 6 without lifting the cap 15. Additionally, it is a good idea to place insulation on the underside of the roof panel. As is clear from the above, according to the present invention, the roof can be constructed with a simple structure that does not use roofing boards or rafters, and by fixing the hangers to the main building and subsequently snapping the roof panels and caps. , on-site work becomes extremely easy.

In addition, since it is made of metal, it is strong and has excellent corrosion resistance, and it is easy to attach accessories. Furthermore, according to the present invention, the joining portions of adjacent roof panels are joined to the hangers while supporting the respective upright side walls and locking the bent portions and the single bent portions, so that both roof panels can be connected together. It can be fastened accurately and stably with simple work. Since the present invention has a configuration in which the roof panel groove is iron-coupled with the hanger, the intermediate portion of the roof panel can be easily supported.
