Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a washer for fixing a deck such as a roof of a prefabricated roof or a roof in the construction field.
[0002]
[Prior art]
Recently, an uneven deck plate has been affixed to the roof or roof of a prefab, the top surface is covered with a heat insulating material, and a synthetic resin sheet is affixed to the surface, reducing weight and saving labor. .
[0003]
Then, in order to fix the heat insulating material or the synthetic resin sheet to the lower deck plate, the screw plate is screwed to the deck plate with a screw screw of a self-drilling screw through a slightly larger washer.
[0004]
In order to be screwed through the deck plate, washers are supplied one by one from a deck plate magazine in which a number of deck plates are stacked to the lower part of the screw bit of the washer mounting tool, and screwed into the washer fixing hole at the center of the washer. Screws are inserted and screwed into the lower deck plate.
[0005]
[Problems to be solved by the invention]
However, when the above-mentioned deck fixing washers are stacked, these washers overlap with almost no gap between the washers, and it is difficult to feed the stacked washers to the screw bit part of the automatic washer attachment with the feed claws. The washer was misfeeded.
[0006]
For this reason, although it is a washer attachment that can save labor at the corner, its performance cannot be fully exhibited, and improvement has been demanded.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention is a deck fixing washer for fixing to a deck plate such as a rooftop or a roof, and includes a gap between the stacked washers. Provided is a deck fixing washer characterized in that three or more protrusions are provided around the center washer fixing hole and the protrusions are arranged in a non-axisymmetric position. is there.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The deck fixing washer according to the present invention is a deck fixing washer for adhering to a deck plate such as a rooftop or a roof, and has a protruding portion that provides a gap between the laminated washers around the washer fixing hole in the center. Three or more are disposed, and the protrusions are disposed at non-axisymmetric positions .
[0009]
As shown in FIGS. 1 and 2, the deck fixing washer 1 is a metal or plastic disk or square plate with a diameter of 70 to 100 mm, and a washer fixing hole 2 is opened at the center thereof. It is provided with a flange 5 of the solid-titration, in a circular recess 3 and 4 and the peripheral edge of the reinforcing.
[0010]
The deck fixing washers 1 are stacked as shown in FIG. 3 and FIG. 4 and supplied one by one to the washer attachments 6. The deck fixing washers 1 are not in close contact with each other. There are three or more protrusions 7 that press the surface side of the deck fixing washer 1 almost uniformly around the washer fixing hole 2 with a press or the like so as to protrude to the back side so that a gap is formed in the washer fixing hole 2. .
[0011]
For example, as shown in FIGS. 1 and 2, the protrusion 7 has a non-axisymmetric position that is slightly shifted from the axially symmetric position such as a 120-degree angular gap with a radius R around the washer fixing hole 2 by x. The pitch circle diameters R at the axially symmetric positions are slightly changed because they are not fitted unless all the recesses 8 on the front side and the projections 7 on the back side of the laminated deck fixing washers 1 are exactly the same. It is preferable that a predetermined gap can be reliably generated between the deck fixing washers 1 as shown in FIG.
[0012]
The protruding amount of the protrusion 7 is preferably such that the deck fixing washer 1 having a thickness of about 1.0 to 3.0 mm is fed into the lower portion of the screw bit 10 with the feeding claws 9. If it is less than 1.0 mm, it is difficult to be hooked on the feed claw 9, and if it is more than 3.0 mm, the deck fixing washer 1 is bulky, which is not preferable.
[0013]
As the protrusion 7, a circular or hemispherical shape is preferable because it is easy to manufacture, but it can also be formed into a square shape or a notch shape, and three or more, preferably three are provided around the washer fixing hole. It is preferable that the deck fixing washer 1 can be supported at three points when the deck fixing washer 1 is overlapped, and a uniform gap can be generated around the deck fixing washer 1. However, in accordance with the above-mentioned gist of the present invention. The shape and quantity of the protrusions can be selected as appropriate.
[0014]
【Example】
FIGS. 1 to 4 show an embodiment of the present invention. From the axially symmetrical position of a 35 mm pitch circle around a washer fixing hole 2 in the center of a steel deck fixing washer 1 having a diameter of 85 mm. The protrusions 7 are formed by pressing at three points at non-axisymmetric positions shifted by 1.5 mm, which is half the diameter of the protrusion 7.
[0015]
Then, the deck fixing washers 1 with the 3 mm-diameter projections 7 protruding 1.5 mm on the back side are stacked as shown in FIG. 3 and mounted on the washer magazine 11 as shown in FIG. As a result, the deck fixing washers 1 were reliably fed one by one. 12 is a deck plate, and 13 is a heat insulating material such as urethane foam.
[0016]
In particular, as a result of projecting the projecting portions at non-axisymmetric positions, uniform gaps were generated between the stacked deck fixing washers, and this was practical.
[0017]
In addition, the number of the protrusions can be increased, the inner and outer doubles can be arranged, and theoretically, it is possible to completely avoid the protrusions on the back side from fitting into the recesses on the front side. .
[0018]
The above has described the disc-shaped deck locking washer, a square shape, can be applied similarly for those of other shapes, also can apply the roof or roofs, walls, and other deck plate mounting portion, further It can also be diverted to rooftops, roofs, wall surfaces, other lightweight concrete, and concrete foundations .
[0019]
【The invention's effect】
As described above, in the present invention, when stacking the deck fixing washers for fixing to the deck plate such as the rooftop or the roof, three or more protrusions are provided around the washer fixing holes in the center of the washer. Since the protrusions are arranged at non-axisymmetric positions, the front and rear deck fixing washers stacked via the protrusions are not in close contact with each other, and a uniform gap is provided between the washers. It is done. For this reason, by stacking and mounting on the washer magazine of the washer mounting tool, the deck fixing washers can be reliably fed one by one to the screw bit part of the washer fixing tool, on the deck plate such as the roof or roof. It can stick.
[0020]
In particular, press the front surface of the washer so that the protrusion protrudes from the back side, and the protrusion on the front side of the washer of this protrusion has a protrusion so that the protrusion of another washer will not enter the gap between the washers. By disposing the protrusions in a non-axisymmetric position, even if the protrusions are pushed out and protruded from the deck fixing washer with a press or the like, the protrusions on the back side are almost fitted into the recesses on the front side. It can be reliably avoided, and there is a uniform gap between the deck fixing washers to be stacked, and the deck fixing washers can be reliably fed one by one to the screw bit part of the washer fixing tool via the feed claws. it can.
[0021]
In addition, by projecting the protrusions in a non-axisymmetric shape slightly shifted from three or more axially symmetric positions to a height of 1.0 to 3.0 mm, before and after laminating as described above While the deck fixing washers are not in close contact with each other, the deck fixing washers can be uniformly stacked at the protrusions, and the deck fixing washers can be stacked without being too bulky.
