Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a device for connecting left and right roofing materials when the roof of a building is laterally roofed.

<Prior Art> Many connecting devices have been proposed for connecting the side edges of left and right roof panels in horizontal roofs of buildings. For example, Japanese Patent Application Laid-Open No. 62-82156 discloses a waste board disposed on the lower surface of the connecting portion of the roofing material, and a receiving material positioned on the upper surface of the waste board to catch the lower surfaces of the side edges of the left and right roof boards. , a connecting device is described that includes a support member located on the upper surface of the receiving member and supporting the upper surfaces of the side edges of the left and right roofing members, and a cover member that adheres to the surface of the support member.

In addition to the above-mentioned connecting device, the positioning of waste boards and receiving materials in conventional horizontal roofs is achieved by placing the waste boards and receiving materials at the open end of the engaging part provided on the upper edge of the roofing material located on the eaves side. This was done by exposing the bent part of the material.

<Problems to be Solved by the Invention> Therefore, when positioning the scrap board, etc., if the bent part of the scrap board, etc. is brought into contact with the engaging part of the reference roofing material more strongly than necessary, the engaging part Since it is deformed, it will be in a position that is set back from the roofing material, and if it is not brought into complete contact with the roofing material, it will be in a position that protrudes from the roofing material. Moreover, since the position of the roofing material used as a reference is not accurate, the position of the waste boards etc. is not constant. Many gaps are created between the waste boards and the roofing material, and these gaps make it easy for rainwater to infiltrate. Therefore, in the conventional device, it is necessary to have a guide piece or other water return piece for guiding the rainwater that enters through the gap to the outside.

In addition, roof construction, including the installation of scrap boards as described above, requires many years of experience and skilled techniques, and in these days of severe labor shortages, there is a strong need for a connecting device that can be easily constructed by unskilled workers. ing.

Means for Solving the Problems> The present invention has been proposed in view of the above, and has an engaging portion bent toward the front side at the upper edge, and a locking portion bent toward the back side at the lower edge. In a horizontal roof constructed by sequentially laying roofing materials, a scrapboard is placed on the lower surface of the part that connects the roofing materials in the horizontal direction, and a scrapboard is placed on the top surface of the scrapboard and the side edges of the left and right roofing materials. It consists of a receiving material that receives the support material, a supporting material that is located on the top surface of the receiving material and supports the upper surfaces of the side edges of the left and right roofing materials, and a cover material that is attached to the supporting material. It is characterized by providing an attached part that covers the lower bent part of the waste board, and positioning the tip of the attached part by making it come into contact with the inner end of the engaging part of the lower roofing board when it is in the installed state. It is something to do. Further, a notch is provided in the center of the downstream end of the covering formed on the front edge of the cover material.

<Function> When in the installed state, the tip of the attached part of the front edge of the receiving material placed on the top surface of the scrap board is brought into contact with the far end of the engaging part provided on the upper level of the roofing material located on the lower side. By doing so, the position of the receiving material can be determined. In addition, the notch provided in the cover material facilitates drainage of water that has entered the connecting portion.

According to the illustrated embodiment, the second locking portion 25 is a deformed hole 26 opened at intervals corresponding to the locking protrusions 17 described above. This deformed hole 26 is a circular shape having an inner diameter larger than the outer diameter of the locking flange 17a so that the locking flange 17a of the locking protrusion 17 provided on the receiving member 6 as the first locking/disengaging portion 16 can pass therethrough. The deformed hole 26 communicates with a long hole 26b whose width is narrower than the outer diameter of the locking flange 17a so that the locking flange 17a can be locked. The protrusion 27 is formed at an appropriate location and protrudes downward. In other words, the deformed hole 26 is opened along the slope of the protrusion 27, so it is opened in an inclined shape. In addition, the long hole portion 26b
A tongue piece 29 is formed by providing a notch 28 on the side thereof, and this tongue piece 29 prevents the supporting member 7 from easily coming off from the receiving member 6. That is, since the locking projection 17 locks on the tongue piece 29, the support member 7 moves and the locking projection 17 locks into the deformed hole 2.
It never deviates from 6.

Further, this support member 7 has support pieces 30 extending laterally from the left and right sides of the groove portion 24, and the support pieces 30 are slightly bent downward and impact on the upper surface of the side edge of the roofing member 1. The roofing material 1 is supported over the entire length C in the depth direction of the roofing material 1. A polymeric piece 31 is provided on the lower edge of this support material 7, which can be bent downward and overlapped with the locking part 3 of the roofing material 1, and the upper edge is provided with a polymeric piece 31 that corresponds to the block 23 of the receiving material 6 as necessary. A shaped contact portion 32 is provided. Note that the overlapping piece 31 has a slight receding angle in the illustrated embodiment. Further, a small notch is provided near the lower end of the support piece 30, and a stopper portion 33 is formed to slightly protrude toward the lower surface side. This stopper portion 33 is a locking piece 3 provided on the cover material 8, which will be described later.
The front edge of No. 4 comes into contact to prevent removal. A notch 35 corresponding to a locking piece 34 of the cover material 8, which will be described later, is provided on the side of the lower end portion of the support piece 3o.

In the illustrated embodiment, a sealing material 36 made of an elastic material such as rubber is provided along the entire length of the lower surface of the support piece 3o to prevent rainwater from entering.

Incidentally, the insertion portion 40 and the stop portion 41, in which the locking piece 34 does not extend, are provided by cutting off the front end side and the rear end side of the locking piece 34. When this cover material 8 is attached to the support material 7, the front edge 34' of the locking piece 34 is locked to the cut edge 33' of the stopper portion 33 of the support material 7 described above.

Next, to explain the construction method, in order to construct a roof using the scrap board 5, support material 6, support material 7, and cover material 8 configured as described above, it is necessary to use a base material such as a field board (not shown in the figure). 1) Place the waste board 5 on top, and make the lower bent part 10 face the engaging part 2 of the roof material l located on the lower side of the slope (FIGS. 14 and 15). Then, the receiving material 6 is placed approximately in the center of this waste plate 5 and the receiving material 6 is positioned. That is, positioning is carried out by bringing the tip 20 of the attachment part 18 of the receiving material 6 into contact with the back end 21 of the engaging part 2 of the roofing material 1 located on the lower side of the slope (FIG. 1). In this way, even if the position of the waste board 5 is somewhat loose, the position of the roofing material 1 to be laid first can be accurately secured.

Then, the locking portions 3 of the left and right roofing materials l to be laid on the upper side of the slope
left and right roofing materials 1 so as to cover the lower bent portion 10 of the waste board 5.
Place the bottom side of the side edge on the surface of the receiving material 6 from the left and right (
Figure 15).

Next, the supporting material 7 is positioned on the surface of the support material 6 on which the side edges of the left and right roofing materials l rest, and the overlapping pieces 31 of the supporting material 7 are placed over the locking portions 3 of both roofing materials 1. By passing the locking protrusion 17 constituting the locking/disengaging means through the circular portion 26a of the deformed hole 26 and moving it toward the elongated hole portion 26b, the locking flange portion 17 is removed.
a to the side end of the elongated hole 26b (Fig. 9,
Figure 6). At this time, since the deformation hole 26 is opened in the protrusion 27, the protrusion 27 comes into pressure contact with the flat part 12 of the support material 6, and the support piece 3o of the support material 7 and the side edge of the roofing material 1 are connected to the roof. The material 1 is closely spaced over the entire length of the material 1 in the depth direction. In the illustrated embodiment, a block 23 is provided at the rear edge of the receiving material 6, so the engaging portion 2 of the roofing material 1 is inserted into the fitting groove 22 of this block 23.
to fit. Further, a sealing material 36 attached to the lower surface of the support member 7 is pressed against the upper surface of the roofing material 1 to reliably prevent rainwater from entering (FIG. 17).

As described above, according to this embodiment, not only can the horizontally elongated roofing material 1 be laid without moving it from side to side, but also it is extremely easy to fasten the support material 7, so that even an inexperienced worker can install it. It can be easily installed, and the working time can be significantly reduced.

Next, the cover material 8 is attached to the support material 7 fixed as described above.
The insertion portion 40 at the rear end of the cover material 8 is placed in the left and right notches 35 provided in the support material 7, and the locking piece 3 is attached.

Thereby, the cover material 8 is supported by the left and right locking pieces 34 sandwiching the support piece 30 of the support member 7. Then, when the cover material 8 is pushed in sufficiently, the adhered piece 37
covers the locking portion 3 of the roofing material 1, and the cut edge 33' of the cover material 8 is locked to a stopper portion 33 provided on the support member 7. Therefore, the roof material 1 will not be rolled up due to strong winds, and the cover material 8 will not fall off (FIG. 16).

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 embodiments described above, and any structure may be modified as long as it is within the scope of the configuration described in the claims. It can be implemented even if For example, the engaging part 2 or the locking part 3 provided on the roof material, or the attached part 18 provided on the receiving material 6
The shapes are not limited to the illustrated embodiments,
As long as they can be held together or in contact with each other, they can be configured in any suitable shape.

<Effects of the Invention> In summary, the present invention is constructed by sequentially laying roofing materials having an engaging portion bent toward the front side on the upper edge and a locking portion bent toward the back side at the lower edge. In a horizontal roof, a waste board is placed on the lower surface of the part that connects the roofing materials in the horizontal direction, a receiving material is placed on the top surface of the waste board and receives the side edges of the left and right roofing materials, and the receiving material is It consists of a support material located on the top surface and supporting the upper surfaces of the side edges of the left and right roofing materials, and a cover material attached to the support material, and a cover material attached to the front edge of the support material to cover the lower bent part of the scrap board. Since the tip of the adhered part is brought into contact with the inner end of the engaging part of the roofing board located below when it is installed, there is no possibility that the engaging part of the roofing material may be crushed. However, since there is no change in the position of the back end, the positioning of the support material using this back end as a reference point is stable, so the position of the support material and cover material relative to the roof material is also stable, and overall it is effective as a connecting device. The rain protection function can be improved. Moreover, since the receiving material that directly receives the roofing material is positioned, the arrangement of the waste boards can be relatively loose, making the construction easy and shortening the construction time. And, the present invention
Since many years of experience and skilled techniques are not required for construction, it is possible to provide a connecting device that can be easily constructed even by amateurs.

Further, by providing a notch in the center of the lower end of the covering piece formed on the front edge of the covering material, drainage of water that has entered the connecting portion can be facilitated without impairing the rain protection function.
