BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hook metal piece used for fixing a roof panel to a body.

[0002]

2. Description of the Related Art As one of the methods for constructing a prefabricated house, a method for constructing a floor, wall, roof, etc. of the house using panels is known. This construction method is a floor panel, a wall panel, or a roof panel by forming a frame body by previously framing a wooden core material in a factory or the like and attaching a face material such as plywood to at least one surface of the frame body. It is a method of constructing a building by manufacturing etc. and assembling these panels at the construction site.

When the roof panel is constructed by the above-mentioned construction method, the roof panel is laid in order on the portion which becomes the roof on the skeleton constructed by assembling the wall panel, the floor panel and the like, and is fixed to the skeleton. When fixing the roof panel to the frame, the roof panel is fixed at the tip of the eaves with hook metal fittings to reinforce it so as to resist wind turbulence. 17 is a perspective view showing a conventional hook metal fitting 31, FIG. 18 is a sectional view showing a state where a roof panel is fixed by the hook metal fitting 31, and FIG. 19 is a sectional view taken along the line AA in FIG.
As shown in these figures, the hook hardware 31 is composed of a central shaft portion 32 and both foot portions 33, 33 integrally formed at both end portions of the central shaft portion 32 and bent in the same direction. Is formed in a substantially U-shape, and the tip end portions 34 of the both end legs 33 are formed in a battledore shape.

The hook metal fitting 31 having the above-described structure is manufactured by bending and pressing a metal round bar, and the central shaft portion 32 is formed by pressing so that the upper and lower surfaces thereof are parallel to each other. The both ends 33 are bent at right angles from the end of the central shaft 32, and the tip 34 is formed into a flat plate by press working. Further, the through hole 34 is formed in the tip portion 34.
a and 34a are formed, and the tip of the tip portion 34 is formed in a pointed shape.

The hook hardware 31 is, as shown in FIGS. 18 and 19, a face member 35a of the roof panel 35.
Is arranged so as to straddle the core member 35c of the roof panel 35 and the tip portions 34, 34 project toward the body side. Further, the projecting tip portions 34, 34 are attached to the outer wall of the body. It is fixed to the wall panel 36 by coming into contact with the constituent wall panel 36 and driving the screw nail 37 into the wall panel through the through hole 34a formed in the tip portion 34. Therefore, the roof panel 35
The core material 35c is held by the hook metal fitting 31, and the tip portions 34, 34 are fixed to the wall panel 36,
It is fixed to the wall panel 36 side by the hook hardware 31,
It is designed to withstand wind turbulence.

[0006]

However, the conventional hook metal fitting 31 has the following problems to be solved. That is, when the hook metal fitting 31 is attached to the roof panel 35, the central shaft portion 32 is located on the upper surface side of the roof panel 35, but on the upper surface of the roof panel 35, after the roof panel 35 is laid, Since roofing and roofing material for waterproofing are laid, if the amount of protrusion of the central shaft portion 32 from the upper surface of the roof panel 35 is large, the roofing and the laying of the roofing material will be hindered. Since it is necessary to press the round bar into a flat plate shape, this press work is not only time-consuming, but the center shaft portion 32 is damaged during the press work, resulting in a poor yield. Further, since the round bar of Muku is pressed, there is a problem that the load on the pressing machine is large, the pressing machine is easily damaged, and the life is shortened.

Further, in order to make the amount of protrusion of the central shaft portion 32 from the upper surface of the roof panel 35 as small as possible, the central shaft portion 32 is strongly driven into the upper surface of the roof panel 35,
The central shaft 32 is embedded in the roof panel 35, or the upper surface of the roof panel 32 is previously dug, and the central shaft 32 is housed in this dug portion. When the central shaft portion 32 is strongly driven, the roof panel 32 may be damaged. In this case, it takes time to repair the damaged portion, and in the latter case, it takes time to form the countersunk portion. is there.

Further, the tip end portion 34 of the hook metal fitting 31 is pressed into a flat plate shape in order to abut and fix it on the wall panel 36. However, this pressing work is troublesome, but when performing the pressing work. Since the tip portion 34 is damaged and the yield is deteriorated, and the Muku round bar is pressed,
There is also a problem that the load on the press machine is heavy, the press machine is easily damaged, and the life is shortened.

The present invention has been made in view of the above circumstances, and it is troublesome and damages occur in the material to reduce the yield. Further, the roof is not subjected to press working for shortening the life of the press, and further, the roof is not used. It is an object of the present invention to provide a hook metal product having a small amount of protrusion from the upper surface of a roof panel when attached to a panel, and a method for manufacturing the same.

[0010]

In order to achieve the above object, the hook metal member according to claim 1 of the present invention is formed by bending a metal strip plate, and has a flat central plate portion. The central plate portion is integrally formed on both sides and is formed in a substantially U-shape including both end legs bent in the same direction, and the both end legs have a V-shaped cross section. The V-shaped bent portion is formed by being bent inward, and the tip end portion of the V-shaped bent portion is further bent inward and overlapped.

According to a second aspect of the present invention, there is provided a hook metal article according to the first aspect, wherein a through hole is formed in the tip portion.

According to a third aspect of the present invention, there is provided a hook hardware according to the first or second aspect, wherein the tip of the tip portion is sharpened.

According to a fourth aspect of the present invention, in the hook metal article according to any one of the first to third aspects, the central plate portion is inclined with respect to a plane including both axes of both foot portions.

According to a fifth aspect of the present invention, in the method for manufacturing a hook metal article, a pair of V-shaped metal strips are bent to have a V-shaped cross section, leaving a central plate portion in the central portion in the longitudinal direction. The bent portions are formed, and then these V-shaped bent portions are bent at substantially right angles in the same direction from both edges of the central plate portion, and then the tip of the V-shaped bent portions is further bent. It is characterized in that the tip portion is formed by overlapping.

[0015]

In the hook hardware of claim 1, since the metal strip is formed by bending and the central plate portion is flat, when the hook hardware is attached to the roof panel, The amount of protrusion of the central plate portion from the upper surface of the roof panel is small, and it is not necessary to perform press working on the central side unlike the conventional hook hardware. Further, since the both-end legs are bent in a V-shaped cross section, the strength of the both-end legs in the axial direction is increased, and the hook metal fitting can be reliably driven in from the upper surface of the roof panel. Further, since the tip of the hook metal piece is formed by bending the tip of the V-shaped bent portion further inward and overlapping the tip end portion, the tip portion has a plate shape. In addition, there is no need to press the tip.

In the hook hardware of claim 2, since the through hole is formed at the tip end thereof, the roof panel can be easily and surely attached to the body by the hook metal by driving the nail through the through hole into the body. Can be fixed. In addition, by driving the nail that fixes the end of the hook metal object into the body through the through hole at right angles to the pulling direction of the hook metal object, the roof panel is agitated by wind and the force in the pulling direction acts on the hook metal object. Even so, the nail is hard to be pulled out, and therefore, the roof panel can be firmly fixed to the body against bending.

In the hook hardware of claim 3, since the tip of the tip is sharp, when the roof panel is fixed to the frame, the hook hardware is easily driven from the tip to the upper surface of the roof panel. Thus, it can be projected to the body side.

In the hook hardware of claim 4, since the central plate portion is inclined with respect to a plane including both axes of both foot portions, this inclination angle should be substantially equal to the roof inclination. Thus, when the hook hardware is driven into the roof panel, the central plate portion follows the upper surface of the roof panel. Therefore, the central plate portion can be housed with a smaller protrusion amount from the upper surface of the roof panel.

According to a fifth aspect of the present invention, there is provided a method of manufacturing a hook metal product, wherein a metal strip is bent into a V-shaped cross section, leaving a central plate portion at the center in the longitudinal direction. V-shaped bent portions are formed, then these V-shaped bent portions are bent at substantially right angles in the same direction from both edges of the central plate portion, and then the tip portion of the V-shaped bent portion is further bent. Since the tip is formed by bending and overlapping, it is possible to manufacture hook metal fittings simply by bending the strip, which is time consuming as in the past and yield is poor, and the life of the press machine is long. There is no need for press work that may shorten the length.
