Description

Metal Tile {A METAL TILE FOR ROOFING}

The present invention relates to a metal tile and a frame for fixing the metal tile, and more particularly, in the metal tile covering the entire roof by partially overlapping the edges of the metal tile, the metal groups overlap each other. The connecting parts are interconnected by a predetermined tensile force to enhance the binding force and watertight action between the metal groups by tension, and the fastening means (nail, screw or rivet) for fixing the overlapping metal groups to the upper hook is provided The upper surface of the metal tile and the upper surface of the upper hook for supporting the metal tile can be connected so that the exterior of the metal tile can be beautifully exposed so as not to be exposed to the outside, and the rain water can not be introduced between the fastening portions of the nails, screws or rivets. It is supported on the bottom of the connection part of the tile uniformly so that it can be installed on the upper hook, that is, the metal tile. Even if the above movement step on the associated worker relates to a metal-based and the hook for fixing so that it does not dent the metal tile or distorted.

Knees are widely used in modern buildings because of their excellent texture, color or physical properties, long life, and ease of processing.

Metallic tiles are manufactured by press molding thin-walled sheet metal materials such as copper, titanium zinc (ZINC), aluminum, stainless steel, and galvalume with a press, so they are easily wrinkled under low pressure. It has the disadvantage of losing or crushing.

As an example of a metal tile, a metal tile having a certain size, as identified in Korean Utility Model Registration No. 20-0244537 (Registration Date: Aug. 17, 2017), may be applied to a roof to prevent rainwater from penetrating or entering the building. In the installation of the metal tile as a whole, it is characterized in that it is installed in such a way as to partially overlap the edge portion of the metal tile.

In addition, a metal device has been developed in which a bent part of the metal part is bent by being bent to be covered by the other part of the metal part, and then the folded part is fixed to the hook by nails, screws, or rivets.

For example, in the Korean Utility Model Registration No. 20-244537 (August 17, 2001) "Metal flat plate", as shown in Figs. 1A and 1B, the metal plate and the body (1a) (1b) is lowered to one side. Although the bent part 1c is formed to be the inclined surface 1f, and the other upward bending part 1d is extended and the nailing part 1g which formed the nail part 1g is proposed, the downward bent part 1c ), The bent shape is formed into a cross-section of approximately 'c' shape, and the upwardly bent portion 1d must be folded (1e) a thin metal tile to hang the downwardly bent portion 1c. Many and complicated, and also because of the folding (1e) of the upward bent portion (1d) there is a factor of unnecessary waste of the metal groups (1a, 1b).

In particular, when the price of the raw material such as copper (Cu) is a high price of the raw material, by forming the folded portion (1e) of the up-bending part, the manufacturing cost is increased due to unnecessary waste of the material, as well as a decrease in productivity due to processing In addition, there is also a problem that often occurs when the metal groups fall in the wind when a natural disaster such as typhoon due to the watertightness and bonding of the connection portion is not strong when connecting the two metal groups through the downward and upward bent portion.

On the other hand, with the metal tile as described above, the upper hanger is first fixed to the roof (concrete slab) surface with screws or pieces or anchor bolts, and then the upper metal hanger is fixed with nails, screws or rivets.

An example of a metal hanger for fixing a current metal fixture is currently published Korean Patent Publication No. 2000-0073147 (published date: 12/05/200, metal structure and installation method) and registered utility model No. 20-0183999 (registration date) 20/20/200 watertightly designed metal fittings and fixtures).

Looking at the conventional metal tile installation structure and installation method, as shown in Figure 2a first fixed the steel truss (1) to the roof of the building and then the cross section on the steel truss (1) do not have the c-shaped iron (2) (P1) or by fixing with screws or welding, and placing the bent upper edge 3a1 of the lower metal tile 3a on the c-shaped iron 2, and placing the lower edge 3b1 of the other metal tile 3b on it. After the part is folded, the overlapped part is fixed to the c-shaped iron (2) using a nail (P1) or a screw or rivet.

However, there is a problem that the gap T occurs between the U-shaped iron 2 and the metal device in the metal device installation structure and installation method.

As described above, the gap T is cut to a predetermined length of the steel 2 having a c-shaped or rectangular cross section and attached to the steel truss 1 or the roof surface, so that the bottom surface of the steel is attached to the ground side by side. There is no choice but to be caused by the difference between the placement angle of the upper surface of the steel and the installation angle of the metal device.

When the gap T is fixed to the U-shaped hardware 2, the worker presses on the connection portion of the metal device nested on the U-shaped steel 2 so that the thickness T is increased by the load of the operator. The problem of crushing or sinking of the thin metal tile is often caused. Also, when the metal tile is screwed to the hardware (2) with screws or rivets, the metal tile is pressed toward the gap (T) by the fastening force. It is rugged, and the head of nails, screws, or rivets is exposed to the outside of the metal tile, so the appearance of the metal tile is not good.

In addition, since it is difficult to flatten the metal tile once it is crushed or recessed, the metal tile should be surrounded so as not to be crushed or crushed when attaching the metal tile, so the workability is not good and the work efficiency is also lowered.

As described above, the above-mentioned Utility Model No. 20-0183999 has been proposed to improve the installation structure of the existing metal machine, and the Utility Model No. 20-0183999 supports the bent portion with the metal machine as shown in FIG. 2B. And a metal truss (1) fixed to the roof for fixing, a bottom plate fixed by screwing on the steel truss (1), and a step length (5a, 5b) provided on the upper part of the bottom plate having different lengths ( It is characterized by consisting of a fastener (5) having a drainage channel (6) between the step (5a, 5b) for draining the rainwater when the rainwater flows in between the connection portion with the metal device while supporting the connection portion of the 3a, 3b) There is this.

However, in the above-described conventional fastener 5, the head of the nail P1 fastened to the joints 5a and 5b of the metal parts 3a and 3b is exposed to the outside, which is not good in appearance and time elapses. Rain water may flow between the fastening surfaces of the nails P1, and when the worker steps on the connecting portions of the metal tiles 3a and 3b, the stepping force may be applied to the surfaces of the metal tiles 3a and 3b by the load pressure. The edge lines of 5a, 5b may be slit, and sometimes the metal surfaces 5a, 5b may be torn.

Therefore, the problem with the metal device and the upper hook posted in the above-mentioned registered utility model No. 20-0183999 is that the connection part between the metal device is crushed or dent when the worker steps on the metal device at the time of attaching the metal device. It is still not resolved.

In addition, Korean Patent Application Publication No. 10-1998-0040853 (published date: 1998.08.17) In the method of constructing a metal tile, in order to fix an upper hook to a concrete slab for fixing a tile, the tile hook hanger (acts like a hook) It is proposed to easily install the same structure as the slope of the concrete slab, attach the lateral lobster to the closing member, and then attach the metal tile on the lateral member, but this also does not solve the problem as described above effectively. have.
