Description

[Detailed Description of the Invention] The present invention relates to a connecting structure of metal roofing plates, and more specifically, the cross section at the connecting part of the roofing plate is connected to the bottom side at the engagement part of the lower end of the metal roofing plate covered on the upper side. The present invention relates to a structure in which a locking portion provided above a roofed metal roof plate is wrapped around, and a connecting structure of metal roof sheets fixed to a roofing board via a mounting piece extending upward from the locking portion.

Figure 1 shows a conventionally known metal roof board, with a mounting piece attached to the top end to give it the appearance of a tiled roof.
At the same time, a fold-shaped locking part 2 provided at the lower part of the mounting piece 1 and protruding upward is provided with a bending line 3 at approximately the midpoint of the vertical length of the hipped roof board, and the bending line 3 A cross section U having an insert piece 6A inside the inclined surface 4 with a bending line 5 as a boundary from the inclined surface 4.
It has a striking cross-sectional shape from the engaging portion 6 which is bent into a letter shape.

When a roof is covered with metal roofing sheets having the above-mentioned structure, the connecting portion between the upper roofing sheet and the lower roofing sheet forms as shown in FIG.

That is, the structure is such that the engaging part 6 of the metal roofing plate P1 placed on the upper side wraps around the locking part 2 of the metal roofing plate P2 placed on the lower side, and the bracket attachment piece 1 is attached via the fastener 7. Field board 8
It becomes a fixed structure.

However, in the above-mentioned metal roof panel connection structure, when the metal roof panel repeatedly expands and contracts in the length direction due to temperature changes, the attachment piece 1
Since the metal roof plate is thin, the fastening hole formed by the fastening tool 7 of the mounting piece 1 expands, and the fastening tool 7 does not perform the fastening role at all, resulting in the problem of the metal roof sheet being blown away during strong winds. .

In this invention, a fixing member for the mounting piece, which is made of an extruded aluminum profile, for example, is attached to the mounting piece from above to ensure firm fixation to the roofing board using a fastener, and the expansion and contraction of the metal roof board due to temperature changes is achieved. To provide a connection structure for metal roof panels that is improved so that the fixation of the mounting piece to the sheathing board can be ensured for a long period of time while suppressing expansion and contraction as much as possible even when the metal roof panels are moved.

Below, a third embodiment of the metal roof plate connection structure of the present invention will be described.
This will be explained with reference to the figures.

In the connection structure according to the present invention, the connecting part of the roof plate or the engaging part 6 of the metal roof plate P□ placed on the upper side wraps around the locking part 2 of the metal roof plate P2 placed on the lower side.

Roof plate P1. P2 has a bottom shape made of a metal plate such as a thin aluminum plate or a galvanized iron plate, and the locking part 2 is provided at the lower part of the mounting piece 1 provided at the upper end of the roof plate P2, and is raised upward and has a rounded cross-sectional shape. It has a hanging shape,
The engaging portion 6 is formed by rolling the lower end of the roof plate P1 inward and bending the rolled portion into a U-shaped cross section so as to have an insertion piece 6A, and the insertion piece 6A is It is inserted into the inside of the stopper 2 so as to be slightly bent.

In order to firmly fix the mounting piece 1 to the roofing board 8 as the metal roof plate repeatedly expands and contracts due to temperature changes, a fixing member 9 made of a somewhat thick aluminum extrusion is placed on the top surface of the mounting piece 1. Then, it is fixed to the roofing board 8 using fasteners 7 such as nails, screws, and anchor ports.

This fixing member 9 has a lower half that enters the inside of the engaging portion 6 and presses the locking portion 2 from the outside to prevent the locking portion 2 from curling up. 4 is provided in combination with a support portion 92 which has the role of supporting from the inside so that it does not dent due to external force.

This fixing member 9 may have any structure as long as it has the strength to at least overlap the mounting piece 1 from above and firmly fix the mounting piece 1 to the sheathing board 8 via the fastener 7.

In addition, in the drawing, 10 is a roofing paper, and 11 is a rafter.

Next, to explain the construction order for creating a connected structure of metal roof plates having the above-mentioned configuration, the roofing board 8 is laid on the rafters 11, the roofing paper 10 is further laid on the roofing board 8, and the metal roofing board is placed on the roof. The roofing is done on top of the printing paper 10.

The metal roof plates P are successively installed from the lower side of the roof to the upper side.

Specifically, once the arbitrary metal roofing board P2 is installed, the fixing member 9 is placed on the mounting piece 1, and the suspender-shaped presser part 91 is fitted so as to press the locking part 2. and fix it to the roof board 8.

Thereafter, the metal roof plate P1 may be placed over the metal roof plate P1 so as to wrap around the locking portion 2 of the metal roof plate P2.

FIG. 4 shows a connecting structure of metal roof panels according to another embodiment of the present invention. It has a mounting piece 1 on the metal roof plate P1, and the locking part 2 is connected to the engaging part 6 of the metal roof plate P1.
There is no change in the basic structure in that it is wrapped in .

The fixing member 9 is fixed to the roofing board 8 with a fastener 7, with a hanger-shaped holding part 93 deformed according to the cross-sectional shape of the locking part 2 and an L-shaped support part 94 attached thereto.

As explained above, the metal roof plate connection structure of the present invention is such that the engaging part at the lower end of the metal roof plate placed on the upper side wraps around the locking part at the upper end of the metal roof plate placed on the lower side. Since the connecting part is fixed to the roofing board via a fastener with a fixing member attached to the mounting piece extending above the locking part, the metal roofing board does not expand or contract due to temperature changes. However, the fixing member and fasteners ensure that the mounting piece is securely fixed to the roofing board over a long period of time, which eliminates the emergency situation where the metal roofing board is blown away by strong winds.

Further, when the fixing member is shaped like a hanger or a groove as in the embodiment, it is possible to prevent the locking portion of the connecting structure from turning up and also to prevent the raised slope from being dented by external force.
