Description

[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a flat roof tile fixture for fixing adjacent upper and lower flat roof tiles in a laying state and a flat roof tile laying method using the same.
[0002]
[Prior art]
Conventionally, as a method of fixing adjacent upper and lower flat roof tiles in the installed state, Japanese Patent Application Laid-Open No. 8-93141 states that “the same-stage joining portion of the crossing portion and the insertion receiving portion is approximately the thickness of one tile In the flat roof tiles that fit together, the hook receiving part is separated at the head side end of the insertion receiving part by a water guide and water return, and has a surface of the same level as the back of the roof tile. The roof tile has a back surface portion higher than the tile surface and has a locking projection that protrudes to the outside of the bottom of the tile body. "Locking wind-resistant thick flat roof tiles in which the locking projections of the tiles restrain the latch receiving portions of the upper tiles on the oblique side and prevent the swinging" are described.
[0003]
[Problems to be solved by the invention]
However, in the above-mentioned locking wind resistant thick flat roof tile, if it is installed in the same way as a general roof tile, the head side of the upper roof tile is fixed to the lower roof tile. Since the locking protrusion protrudes more, there has been a problem that the locking protrusion is liable to be damaged during the manufacturing process and the subsequent packing, transportation, and laying operations.
[0004]
[Means for Solving the Problems]
The present invention is based on the above-described prior art, and in view of the problem that the locking projection is easily damaged, the L-shaped nail that is driven into the roof base through the lower flat roof tile in the installed state, and the intermediate portion of the L-shaped nail Provided with a stopper that abuts the upper surface of the lower flat roof tile, and the upper locking portion formed by bending the L-shaped nail when the stopper is driven into the roof base is the upper flat roof tile in the installed state. The flat roof tile fixture is formed by placing the stopper on the lower portion of the external fitting tube to the L-shaped nail and surrounding the flange portion. A hole is penetrated and driven into the roof base, and the lower flat tile is fixed to the roof base, and the head side of the upper lap of the upper flat tile is locked to the upper locking portion of the flat tile fixing tool. By installing it, the top of the flat roof tile can be separated by a separate fixture. Both flat tiles and enables fixing, to solve the above problems.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a plan view showing a state in which a flat roof tile is installed using the flat roof tile fixing tool according to the present invention, and FIG. 2 is an enlarged view of an essential part of the XX cross section of FIG. is Ru enlarged view der the Y-Y cross section of FIG.
As shown in FIGS. 2 and 3, in the installed state, the flat roof tile is fixed by fixing the head side of the upper flat roof tile Wa by penetrating the bottom side of the lower flat roof tile W adjacent in the vertical direction into the roof base B. In the fixing metal fitting 1, the upper flat plate is bent at a right angle, and the lower flat plate is formed in the middle portion of the L-shaped nail 3 in which the upper receiving portion D of the upper flat roof tile Wa is formed. A stopper 4 that contacts the surface of the roof W is provided.
[0006]
Further, in the stopper 4, the locking part 2 in the L-shaped nail 3 is fixed at a position directly above the locking receiving part D, and this position is the type of the target flat roof tile W, Wa, Since it differs depending on the shape, the flat roof tile fixing fitting 1 that matches the shape is used.
As shown in FIGS. 2 and 3 , the stopper 4 is formed by providing a flange 9 around the lower portion of the outer fitting tube 8 to the L-shaped nail 3.
Specifically, the flange portion 9 is formed in a tapered shape by gradually expanding the diameter of the lower portion of the outer fitting tube 8.
The stopper 4 is preferably formed in a bowl shape so as to close the penetration portion 5 of the flat roof tile fixing bracket 1 (L-shaped nail 3) formed on the bottom side of the flat roof tile W below. Further, it is desirable to provide a waterproof packing 6 below the stopper 4.
[0007]
Further, in the flat portion of the flat roof tile W in the through portion 5 of the flat roof tile fixing bracket 1, it is a normal nail hole 7. However, although not shown, the through portion 5 may be formed separately from the nail hole 7. .
As the lock receiving portion D, as shown in FIG. 2 and 3, and the head side of the underlap portion UL above the flat roof tile Wa.
[0008]
Next, a method for installing a flat roof tile using the flat roof tile fixing bracket according to the present invention will be described.
First, the girder is driven by driving the flat roof tile fixing bracket 1 penetrating through the bottom portion 5 of the flat roof tile W placed on the roof base B until the stopper 4 comes into contact with the upper surface of the flat roof tile W. Repeat in the direction.
Next, the flat roof tile Wa is laid in the direction of the row so that the locking receiving portion D of the flat roof tile Wa to be installed is inserted between the flat roof tile W and the locking portion 2 of the flat roof tile fixing bracket 1. .
Then, the lower flat roof tile W is fixed to the roof base B by the flat roof tile fixing bracket 1, and the locking portion 2 is positioned immediately above the locking receiving portion D of the upper flat roof tile Wa, so that the flat roof tile Wa. Since the head side of the flat roof tile is also fixed, the flat roof tile Wa does not rise even in strong winds.
[0009]
【The invention's effect】
In short, the present invention is provided with a stopper 4 that abuts the upper surface of the lower flat roof tile W at the intermediate portion of the L-shaped nail 3 that passes through the lower flat roof tile W in the installed state and is driven into the roof base B. 4 so that the upper locking portion 2 formed by bending the L-shaped nail 3 in the state of being driven into the roof base B is positioned immediately above the underlap portion UL of the upper flat roof tile Wa in the installed state. Since it is provided, the lower flat roof tile W can be fixed to the roof base B with one flat roof tile fixing bracket 1, and the top side of the upper flat roof tile Wa can also be fixed. By fixing the head side of Wa, the constructed tile roof can be provided with a wind resistance function.
Furthermore, by providing the stopper 4, the locking receiving portion D of the upper flat roof tile Wa can be reliably inserted between the locking portion 2 and the lower flat roof tile W of the driven flat roof tile fixing bracket 1. Since the space is automatically formed, the installation work of the upper flat roof tile Wa can be performed without any trouble.
Since the stopper 4 is formed by surrounding the flange portion 9 around the lower portion of the outer fitting tube 8 to the L-shaped nail 3, the flange portion that actually functions as the stopper 4 depending on the length of the outer fitting tube 8. Since the position of 9 with respect to the L-shaped nail 3 is automatically determined, the positioning of the stopper 4 can be simplified, and the penetrating portion 5 can be closed by the flange 9.
[0010]
Further, since the stopper 4 is provided so as to close the penetrating portion 5 of the L-shaped nail 3 in the lower flat roof tile W, the roof base B is formed from the penetrating portion 5 of rainwater blown from between the upper and lower flat roof tiles W and Wa. Ru can be prevented from entering the.
Furthermore, since the packing 6 is provided at the lower part of the stopper 4, the packing 6 is in close contact with the upper surface of the lower flat roof tile W and closes the penetrating part 5, thereby preventing rainwater from entering the penetrating part 5 more reliably. Its practical effect is great.
