Description

[0001]
[Industrial applications]
The present invention relates to a tile fixing nail for fixing a tile to a tile crosspiece or the like.
[0002]
[Prior art]
As shown in FIG. 10, the tile fixing nail C of the conventional example has a hammering head 2 extending to the side of the pile portion 1, and a bent portion inclined downward at the tip of the hammering head 2. 4 is formed. As shown in FIG. 11, the upper surface 1a is inclined on the peripheral surface of the pile 1 so as to reduce the diameter in the driving direction of the pile 1, and the pile 1 is driven into the upper surface 1a. A circumferential groove 1c is formed that has a gap in the direction and faces the lower surface 1b that is substantially perpendicular to the driving direction and faces each other.
[0003]
In order to lay a tile using the above-described tile fixing nail C, the following procedure is performed. That is, as shown in FIGS. 12 and 13, first, the lower edge of the second roof tile D2 located above the first roof tile D1 is superposed on the surface side of the upper edge of the first roof tile D1. In this state, the tile fixing nail C is driven into the tile bar 5 located just below the overlapping portion of the first tile D1 and the second tile D2 from the upper right side of the overlapping portion, and at the same time, the tile fixing is performed. The hammering head 2 of the nail C is locked on the surface of the second roof tile D2. Next, a screw nail E is driven into the insertion hole 6 formed in the upper edge of the second roof tile D2. The above process is repeated from the eaves side to the ridge side.
[0004]
[Problems to be solved by the invention]
In the tile fixing nail C of the conventional example, the hammering head 2 can be driven into the roof 5 by hitting the hammering head 2 from directly above with a hammer or the like. The workability is excellent because it can be locked. However, if the blow with a hammer or the like is repeated, the hammering head 2 is bent downward and cannot be locked along the surface of the tile. Alternatively, there is a problem that the hammering head 2 breaks due to metal fatigue or the like. If such a problem occurs during the construction, the tile fixing nail C once driven into the tile bar 5 has to be extracted and a new tile fixing nail C must be re-punched, so that much labor and time are required. . In addition, if the hammering force of the hammer or the like is reduced, the time required for driving the tile fixing nail C becomes unnecessarily long.

[0010]
【Example】
Hereinafter, an embodiment of the tile fixing nail of the present invention will be described. The same components as those in the conventional example are denoted by the same reference numerals, and the description thereof will be omitted.
[0011]
As shown in FIG. 1, a tile fixing nail A according to a first embodiment of the present invention is configured such that a rear end portion of a pile 1 made of a steel wire having a circular cross section with a sharpened tip 1a is bent at a right angle. The hammering head 2 is thereby formed, and as shown in FIGS. 2 and 3, a protrusion extending in the projecting direction of the hammering head 2 is formed on the upper surface near the base end 2 a of the hammering head 2. Article 3 is provided. The ridge 3 is preferably formed integrally with the hammering head 2 without increasing the number of components, but may be formed by brazing a metal piece or the like. Further, the number, arrangement and the like of the ridges 3 are not limited to those shown in FIG. 3, but may be arranged on both sides of the hammering head 2 as shown in FIG. 4, for example.
[0012]
According to the roof fixing nail A configured as described above, since the ridge 3 acts as a reinforcing rib of the hammering head 2, the hammering head 2 is prevented from being bent by an impact of a hammer or the like. it can. Further, when the vicinity of the base end 2a of the hammering head 2 is hit with a hammer or the like, the ridge 3 is crushed first to reduce the impact and protect the vicinity 2a of the base end of the hammering head 2. The hammering head 2 can be prevented from breaking. Further, since the pile portion 1 and the hammering head 2 are integrally formed by bending a steel wire, manufacturing is extremely simple.
[0013]
Furthermore, since the ridge 3 is provided near the base end 2a of the hammering head 2 and not provided near the distal end 2b, the hammer or the like is used to drive the pile 1 into a tile bar or the like. The vicinity 2a of the base end of the batter 2 is located relatively higher than the vicinity 2b of the tip. For this reason, even if the hammer or the like is used with a slight inclination, it is possible to reliably hit only the vicinity 2a of the base end, so that there is no need for an operator or the like to pay attention not to hit the vicinity 2b of the tip carelessly. Therefore, if the tile is laid by using the tile fixing nail A, the work can be easily performed even at a high place where the scaffold is unstable.
[0014]
In the first embodiment, the ridge 3 is provided on the upper surface of the hammering head 2, but may be provided at the center of the lower surface of the hammering head 2 in the width direction as shown in FIG. Alternatively, as shown in FIG. 6, the hammering head 2 may be provided separately on both sides of the lower surface. In this case, when the hammering head 2 is hit with a hammer or the like as described above, the ridge 3 is crushed first to reduce the impact, and even if the hammer is used with a slight inclination, the hammering head is used. Although the advantage of being able to reliably hit only the base 2a near the base end 2 is lost, the advantage is obtained that the bending rigidity of the hammering head 2 can be improved without increasing the total length of the pile 1 by the rise of the ridge 3. Can be Further, by providing a circumferential groove 1c along the peripheral surface of the pile 1 as in the conventional example, the frictional force when the pile 1 is driven into a tile bar or the like is increased, and the pile 1 is easily pulled out. It may not be necessary.
[0015]
Next, as shown in FIG. 7 to FIG. 9, the roof fixing nail B of the second embodiment of the present invention The thickness T of 2a is increased in the driving direction of the pile portion 1 near the distal end 2b, and the width W of the proximal end 2a is smaller than the distal end 2b. The pile 1 and the hammering head 2 are integrally formed by bending the rear end of the pile 1 made of a wire having a circular cross section at a right angle, as in the first embodiment. .
[0016]
According to the tile fixing nail B configured as described above, a high strength can be secured against the impact received from the driving direction of the pile portion 1, so that the hammering head 2 is prevented from being bent by the impact of a hammer or the like. it can. In addition, even if the vicinity of the base end 2a of the hammering head 2 is repeatedly hit with a hammer or the like, the vicinity of the base end is not thinly crushed and the strength is not insufficient or the breakage does not occur. Further, since only the vicinity of the base end 2a of the hammering head 2 protrudes upward from the ridge 3, when the pile 1 is driven into a tile bar or the like as in the first embodiment, With respect to a hammer or the like, the vicinity 2a of the base end of the hammering head 2 is located relatively higher than the vicinity 2b of the tip. Therefore, there is no need for an operator or the like to pay attention so as not to inadvertently hit the tip 2b of the hammering head 2, and construction can be easily performed even at a high place where the scaffold is unstable.
[0017]
In the second embodiment, the vicinity of the base end 2a of the hammering head 2 is bulged upward, but may be bulged below the hammering head 2. In this case, even if the hammer or the like is used with a slight inclination, the advantage that only the vicinity 2a of the base end of the hammering head 2 can be reliably hit is lost, but the whole length 2a of the base 1 near the base of the pile portion 1 bulges. The advantage is obtained that the bending rigidity of the hammering head 2 can be improved without increasing the amount. Further, by providing a circumferential groove 1c along the peripheral surface of the pile 1 as in the conventional example, the frictional force when the pile 1 is driven into a tile bar or the like is increased, and the pile 1 is easily pulled out. It may not be necessary.
[0018]
【The invention's effect】
According to the tile fixing nail according to the first aspect, since the hammering head can be prevented from being bent or broken by an impact when hit with a hammer or the like, a new tile fixing nail is re-punched during construction. Saves time and effort. Further, by further increasing the hitting force of a hammer or the like, the time required for driving the tile fixing nail into the tile crosspiece or the like can be reduced. Further, when the vicinity of the base end of the hammering head is hit with a hammer or the like, the ridge is crushed first to reduce the impact and protect the vicinity of the base end of the hammering head. Further, since the pile portion and the hammering head are integrally formed by bending a steel wire rod, manufacturing is extremely simple. In addition, since the ridge is provided near the base end of the hammering head and not near the tip, when driving the pile into a tile bar etc. Since it is located relatively higher than the vicinity, even when a hammer or the like is used with a slight inclination, only the vicinity of the base end can be reliably hit and the construction can be easily performed.
[0019]
According to the tile fixing nail according to the second aspect, since high strength can be secured against the impact received from the driving direction of the pile, the hammering head is bent or broken by the impact when hit with a hammer or the like. This eliminates the need for reworking new tile fixing nails during construction and saves time and effort. Further, by further increasing the hitting force of a hammer or the like, the time required for driving the tile fixing nail into the tile crosspiece or the like can be reduced. Also, similar to the tile fixing nail of claim 1, the vicinity of the base end of the hammering head is relatively higher than the vicinity of the tip, so even if the hammer or the like is used with a slight inclination, the vicinity of the tip is not good. It is possible to hit only near the base end without hitting easily, and construction is easy.
