Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a horizontal roof that is made of metal plates from the eaves to the ridge. This is a horizontal roof in which the connecting part of the roofing material that has the joint part is supported by side pieces provided on the waste board.

<Prior art> A base member is provided on the back side of the roofing material that has a locking part on the front edge and an engaging part on the rear edge, and the waste board is stored in the gap between the connecting parts of the roofing materials that are adjacent to each other on the left and right. A horizontally thatched roof is known, for example, from Japanese Patent Laid-Open No. 63-315756.

That is, in the horizontal roof, the width of the base member is made shorter than the width of the roofing material, and a gap is created at the back end of the roofing material where the base member is not present. At the same time, a support member having a cross-sectional shape with an opening on the side is attached to the waste board by placing the base plate part and the support plate part, and the side opening of this support member is installed. The side edges of the roofing material adjacent to the roofing material are inserted, and further members are attached to the supporting material.

By the way, in the case of a horizontal roof, since the locking parts and the engaging parts of the vertically adjacent roofing materials are engaged with each other, the overall slope of the roof such as roof boards and rafters and the slope of each roofing material are different. The slope is different. Therefore, a space having a triangular cross-sectional shape is created between the roofing board or the like and the roofing material or base member.

This space reduces the strength of the roof shingles, and if deformation occurs due to lack of strength, especially at the joints that connect the left and right roof shingles, that is, the waste shingles, this can lead to serious problems such as rainwater infiltration.

Therefore, conventional methods have been used to deal with the decrease in strength caused by the space, such as by arranging back-up material in a rib shape that corresponds to the shape of the space, or by increasing the strength of the waste board and using the reinforcing effect of the waste board. There is.

<Problem to be solved by the invention> However, installing a dedicated back-up material not only takes time and effort to install, but also increases the weight of the roof and increases raw material and construction costs. On the other hand, even if sufficient strength is given to the waste boards and the reinforcement effect of the waste boards is expected, if a worker climbs onto the roof surface for inspection etc. after the construction of the M-root and steps on it, etc. There is a risk of deformation if a concentrated load is applied to the waste plate part.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and the invention described in claim (1) is a horizontally elongated device having a locking portion on the front edge and an engaging portion on the rear edge. The roofing material is horizontally thatched, and the waste boards are placed inside the joints of the adjacent roofing materials on the left and right, and the retaining part of the roofing material located on the upper level, which is the one building side, is used for the roof located on the lower level, which is the eaves side. In a horizontal roof that is engaged with the retaining part of the roofing material, a fitting piece corresponding to the engaging part of the roofing material is provided on the front edge of the scrap board, and a vertical piece corresponding to the engaging part of the roofing material is provided on the rear edge. A side piece whose lower side slope corresponds to the slope of the base is provided on both sides of the waste board, and a water return means is provided on the upper surface along the slope direction of the roof, and the lower edge of the side piece of the waste board is provided. The connecting portion of the roofing material is placed on the base, and the connecting portion of the roofing material is positioned on the upper surface of the wasteboard, so that the connecting portion of the roofing material is supported by the side pieces of the wasteboard.

Moreover, the invention described in claim (2) is one in which (11 legs have legs extending from the lower edges thereof to make surface contact with the base.

According to the invention described in claim (1), the slope of the side piece provided on the side edge of the waste board absorbs the difference in slope angle between the roofing material and the roof base, and the roofing material is It can be supported by the side pieces. Moreover, according to the invention described in claim (2), the load applied to the waste board can be dispersed and supported by the legs extending from the lower edges of the side pieces and making surface contact with the base.

The double water return means (18.18") provides good rain protection.

It should be noted that in FIGS. 4 to 8, unexplained symbols have the same structure as the embodiment shown in FIGS. 1 to 3, and therefore their explanation will be omitted.

Although the present invention has been described above with reference to the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, and can be carried out as appropriate without changing the configuration described in the claims. For example, the locking part and the engaging part may have a configuration other than that shown in the drawings, as long as they can engage the roofing materials located above and below, and the legs may extend inwardly or outwardly. Alternatively, it may extend in both directions. Further, the water returning means may have any configuration as long as it can drain rainwater that enters from the connecting portion of the roofing material to the upper surface of the roofing material located below.

<Effects of the Invention> In summary, the present invention provides a side piece corresponding to the slope of the base on the side edge of the pile board so as to absorb the difference between the slope of the base of the roof and the slope of the roofing material. The connecting parts of the materials can be supported with scrap boards.

Therefore, the strength against the load of the roofing material can be increased without separately arranging supporting members, and it is possible to provide a horizontal roofing M-root that is inexpensive and has sufficient strength without requiring much effort in laying. . According to this roof, even if a concentrated load is applied, such as when a worker steps on the connecting part of the roof material, it will not deform. Furthermore, since the legs extend from the lower edges of the side pieces, the load can be dispersed to the base, making it possible to withstand the load caused by a worker standing on it, the load caused by accumulated snow, etc. Furthermore, since the lower edges of the side pieces do not damage the base or peel off the paint, rust and corrosion are prevented and durability is improved.

Further, according to the present invention, there is no need to provide a separate member to support the roof material, so there is no increase in the weight of the roof due to the provision of the separate member. Therefore, there is no need to increase the strength of the roof frame of buildings such as beams and purlins (it can be installed on top of conventional roof frames, and has extremely high practical value).

Furthermore, the waste board is placed on the base at a constant slope by the side pieces,
Since the roofing materials are laid on these waste boards, the inclination of each roofing material is constant based on the inclination of the waste boards, and the slope of the roof is uniform, resulting in an extremely good appearance.
