Description

[Detailed description of the invention] The present invention is applicable to roof structures in areas where different types of roof plates are connected to a base roof plate, such as a daylighting area formed in the main roof surface of a factory, warehouse, or arcade. The purpose is to provide a roof structure that has a relatively flat roof surface, is completely waterproof, and is easy to construct.

A roof of a different type on the base roof plate is used to form a roof for daylighting in the main roof surface, or to close an opening made in the main roof surface due to renovation, demolition of a part of a building, etc. In order to connect the boards, conventionally, the different types of roof boards are connected using a flat roof structure using many members.
The connected roof panels of different types protrude from the main roof surface, resulting in a structure that not only looks bad but also tends to have incomplete water blocking, making it relatively easy to replace the connected roof panels of different types. Even if there were, the structure itself for connecting to the base roof plate would be extremely complicated and require a lot of man-hours, as well as being heavy.

The present invention provides a roof structure free from the above-mentioned drawbacks by adopting the structure described in the claims of the utility model registration.

The configuration of the present invention will be described below with reference to the illustrated embodiments.

In Figure 1, a daylighting area 4 is formed on a part of a raw roof board 2 which is a folded corrugated plate forming the main roof surface 1, and a base roof board 2 which is a transparent synthetic resin corrugated board and a roof board 3 of a different type. This is an example of a roof structure.

As shown in FIG. 2, an opening 5 is formed in the base roof plate 2 at a portion where a daylighting portion is to be formed. As shown in FIG. 2, the left and right side edges 6, 7 along the opening 5 are formed into bulge portions 8, 9 extending in the inclination direction SS over the entire length of the opening 5.

In the illustrated example, the peaks of the base roofing board 2, which is a folded corrugated board, are left as they are.
By leaving it in place, it becomes the bulging strip.

Connecting fittings 10.1 of the roof panel 3 are attached to the bulging strips 8, 9.
1 is placed and fixed.

FIG. 2 shows the connecting portion between the bulging strip 9, the connecting fitting 11, and the roof panel 3, and the connecting fitting 10 side is also connected with the same structure in a symmetrical arrangement.

The main body part 12 of the connecting fitting 11 is placed on the bulging part 9 and fixed thereto, and the main body part 12 has a downward cross-section in the shape of a parenthesis, and one side thereof has the following shapes.
An upper piece 14 is located on the same plane as the top surface 13 of the main body part 12 and extends toward the bulging strip part 8 on the other side, and an upper piece 14 extends integrally from the main body part 12 below the upper piece 14. A lower piece 15 is provided.

As shown in FIG. 3, a hollow portion 16 is formed on the lower surface of the tip of the upper piece 14, and water-stopping scales 17 made of synthetic rubber or the like are fitted into this portion.

Further, the lower piece 15 is provided with a groove 18 at its base, and the upper piece 14 and the lower piece 15 are integrated to form a gripping edge having a Y-shaped cross section.

The above-mentioned connecting fittings 10.11 are formed to be slightly longer than the both side edges 6, 7 of the above-mentioned opening 5, and are at the ends 10' of the Kinoshita.

11' is located on the main roof surface 1.

In the embodiment shown in FIG. 1, the main roof surface 1 corresponding to the ends 10', 11' is formed by a separate member 19 shown in FIG.
In this example, the member 19 includes a flat surface 20 that covers a partially cut out portion of the peak of the base roof board 2 made of a folded corrugated plate, and a peak 21 that is fitted into the peak that continues to the cut out portion. , a fitting portion 22 , 23 that fits into the above-mentioned bulging strips 8 and 9 , a lid piece portion 24 that seals the valley of the base roof board 2 , and a standing wall portion that rises from the rear end edge of the flat surface 20 . 25, and a waterproof packing 25' made of foamed synthetic resin that is adhered and fixed to the upper surface of the waterproof packing 25'.As shown in FIG. On the flat surface 20, the ends 10' and 11' of the aforementioned connecting fittings 10° 11 are located, and on the waterproof gasket 25' on the upper surface of the vertical wall section 25, different types of roof panels 3 are placed as described later. The lower edges 3' of the wood are brought into close contact.

The upper piece 14 and the lower piece 15 form a clamping edge with a Y-shaped cross section. Between the connecting fittings 10 and 11, a horizontal bar 26 is inserted between the connecting fittings 10 and 11. A roof board 3 such as a corrugated board is inserted and fixed.

The horizontal beam 26 in the illustrated example has a cross-sectional shape as shown in FIG. Connection fitting 10
．． 11, and the roof board 3 is watertightly inserted and supported between the upper surface of the horizontal beam 26 and the water-stop scales 17 on the lower surface of the lower end of the upper piece 14 of the connecting fitting 10.11. There is.

The underwater edge 3' of the roof board 3 is in close contact with the upper surface of the vertical wall portion 25 of the flat surface 20 of the member 19, which is a part of the main roof surface 1, via a waterproof gasket 25'.

The edge portions of the roof board 3 and the connecting fittings 10.11 on the water side are covered with a cover 31 having a flat U-shaped cross section and extending from below the board 30 to a position covering the edge.

Reference numeral 32 in FIG. 1 indicates waterproof scales. Since the roof structure according to the present invention has an inclined configuration, the opening above the water is covered by the cover 31.
There is no risk of water intrusion due to the presence of the opening, and the upper part of the connection fitting and the roof plate are in close contact with the left and right edges of the opening, so that water can be sufficiently blocked. The grooves guide water to the main roof surface under the tree and prevent it from flowing indoors.

In addition, the presence of waterproof gaskets in the opening below the water completely prevents rainwater from blowing in.

In addition, the upper piece of the connecting fitting that forms the clamping edge is located in the same plane as the top surface of the main body, and this clamping edge allows
Since the different types of roof panels to be connected are fixed, the roof surface formed by the connected roof panels and the main roof surface can be made to exist approximately in the same plane.

The roof board to be connected to the above-mentioned connection fittings may have its bottom edge extended to the eaves, and the above-water edge may also be extended to the board, and in this case, it can be easily waterproofed by using waterproof packing. It can be called a structure.

The present invention has the structure 9 described in detail above, and connects the roof surface made of different types of roof sheets to the main roof surface made of plain roof sheets using a conventional bulging method using beams, rods, etc. Compared to the structure, it can be connected while maintaining a relatively flat external shape that hardly bulges, giving a good appearance, and being completely water-blocking, preventing water from flowing indoors.
Construction is also simple, such as fixing the connecting fittings, which are integrated single parts, inserting and fixing the roof panels to be connected, and interposing waterproof gaskets, which can significantly reduce the number of parts and man-hours. In addition to the connection fittings, there are
Beams, rods, etc. are completely unnecessary, making the structure extremely simple and lightweight.
