Description

[Detailed description of the invention] [Industrial application field] This invention has a stop mechanism using only a threaded portion, and allows construction boards, etc. to be attached at a certain height (depth) or interval. Furthermore, the present invention relates to a fixing device that allows for orderly attachment of inner side architectural boards that are tilted and deformed at overlapping points, and that can be easily penetrated even through insulation materials such as rock wool provided between upper and lower architectural boards. .

[Conventional technology and its problems]

Conventionally, a heat insulating envelope such as a double roof or wall is constructed by sandwiching a relatively elastic heat insulating material between the inner building board and the outer building board. However, if you tighten it from the outside construction board to the main building or rim with a general drill screw (fixing tool), etc., the tightening point of the outside construction board will become dented, resulting in a poor appearance. Not only that, but it also had the disadvantage of halving the insulation performance of the recessed areas.

In addition, if you try to fix a part of an outer enclosure such as a roof or wall where peaks and valleys are continuous without a metal fitting with a drill screw (fixing tool), etc., as shown in Figure 5, the lower part of the overlapping part will appear. The problem was that the ridges of the bolts were tilted and deformed, making it impossible to tighten them or making it impossible to secure them in a watertight manner.

In addition, a heat insulating material such as rock wool provided between the upper and lower construction boards has the disadvantage that the fixing tool cannot be easily penetrated.

[Means to solve the problem]

Therefore, in order to solve the above problem, the inventor conducted extensive research and came up with the idea: a drill part is provided at the lower end of the shaft part, a right-hand thread part is screwed above this part, and the right-hand thread part A guide piece that can be broken off with an appropriate force is provided protrudingly on the circumference of the shaft part between the and the drill part,
By using this fastener, a left-hand threaded portion is threaded substantially continuously above the right-hand threaded portion, and an upper right-hand threaded portion is threaded onto the upper portion of the shaft portion. For constructing a heat insulating envelope such as a double roof or wall in which a relatively elastic heat insulating material is sandwiched between the inner building board and the outer building board. Even if these are tightened all at once from the outside side, the screw part alone has a stop mechanism, and construction boards, etc. can be attached at a certain height (depth) or interval, and the construction on the outside side. The tightening parts of the construction boards do not dent, giving an elegant appearance and improving insulation performance.Furthermore, the construction boards on the inner side, which are tilted and deformed at overlapping parts, can be corrected and installed in an orderly manner.Furthermore, Even when the heat insulating material is rock wool or the like, the fixing tool can be penetrated satisfactorily, thus solving the above problem.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 6.

A is a bolt-shaped fastener that can be drilled,
Commonly known as a drill screw, it is composed of a shaft part 1 and a bolt head 2, and the lower tip of the shaft part 1 has a drill part 1a for drilling holes. A right-hand threaded portion 1b is threaded on the periphery, and a left-hand threaded portion 1c is threaded on the upper side of the right-hand threaded portion 1b and substantially continuous therewith. Further, an upper right-hand threaded portion 1d is screwed onto the upper portion of the shaft portion 1. The right-hand threaded portion 1b is a tatsupin screw, the left-hand threaded portion 1c serves as a rotation stopper, and the upper right-hand threaded portion 1d serves to pull up the plate material.
In some cases, the screw pitch is larger than the pitch of the screw, or the height of the screw thread is increased.

Reference numeral 1e denotes a guide piece, which is placed at an appropriate position on the periphery of the shaft portion 1 between the drill portion 1a and the right-hand threaded portion 1b, so that the guide pieces are approximately
They are protruded as a pair, 180 degrees apart. The guide piece 1e has a thin wall thickness, and before the right-hand threaded portion 1b of the fixing member A is screwed onto the structural member 3 such as the purlin or the rim, the guide piece 1e has a thin wall thickness, and the guide piece 1e has a small wall thickness, and the right-hand threaded portion 1b of the fixing member A is screwed onto the structural member 3 such as the purlin or the trunk rim. As shown by the respective dotted lines, when an appropriate force is applied, the guide pieces 1e, 1e break and disappear. Specifically, when the drill portion 1a penetrates into the structural member 3 and then the guide piece 1e starts to come into contact with the structural member 3, the guide pieces 1e, 1e are damaged.

4 in the figure is a corrugated construction board;
As shown in FIG. 6, there are peaks 4 on both sides of the valley 4a.
b and 4b are integrally formed, and are made of a metal plate having an appropriate length or length in the longitudinal direction. If the bottom of the valley portion 4a is wide, one or more intermediate peak-like portions 4c may be formed as needed, as shown in FIG. In addition, the architectural board 4
A heat insulating material of an appropriate thickness is pasted on the back side of the board, if necessary. Reference numeral 5 is a plate-shaped heat insulating material such as foamed synthetic resin, rock wool, glass wool, or wood wool board, which is a relatively elastic material. 6 is a washer, 7 is a gasket, and 8 is a head gasket made of synthetic resin, etc., which prevents damage such as scratches to the top surface of the washer 6 due to burrs on the bottom surface when the bolt head 2 of the fixture A rotates. It's for a reason.

[Effect]

First, to describe the installation of the heat insulating envelope as shown in FIG. 4, an inner construction board 4 is placed on the structural member 3, and a relatively elastic A heat insulating material 5 made of foamed synthetic resin or the like is laid down, and the outer construction board 4 is placed on top of this. Then, the drill part 1a of the fixing tool A of the present invention is brought into contact with the bottom surface of the valley part 4a of the outer building board 4, and the fixing tool A is rotated to penetrate the heat insulating material 5.

At this time, the guide pieces 1e, 1e move around the fixing tool A of the heat insulating material 5, and penetrate the lower inner construction board 4, and then penetrate the structural material 3 with the drill part 1a. A hole is bored, and then the guide pieces 1e, 1e are inserted into the metal structural member 3.
If it hits the top surface, it will not be able to penetrate inside and will break off and disappear. Then, by further rotating the fixing tool A, screwing the right-hand threaded part 1b into the structural member 3, and further rotating it, this time the left The threaded part 1c is the structural material 3
It bites into the already formed screw thread, stopping the rotation and making it impossible to tighten, completing the installation of the heat insulating envelope.

Also, to describe the installation of the outer enclosure as shown in FIGS. 5 and 6, a building board 4 is placed on the structural material 3, and the peak part 4b of the building board 4 is The crests 4b of the construction boards A are overlapped, and then the fixing tool A of the present invention is inserted while rotating from the appropriate position at the top of the overlapped part of the ridges 4b, 4b of the construction boards 4, 4, and the drill part 1a is used to tighten the structure. A through hole is drilled in the material 3, the guide piece 1e hits the top surface of the structural material 3 and breaks, and by further rotation, the right-hand threaded portion 1b is screwed into the structural material 3, and at this time, the polymerization occurs. The lower ridge 4b of the location is tilted and deformed as shown in Fig. 5, but as it rotates further, the upper right-hand threaded portion 1d causes the ridge 4b to rise and come into close contact with the outer ridge 4b. At the same time, the left-hand threaded portion 1c bites into the already formed screw thread of the structural member 3, stopping the rotation and making tightening impossible, completing the installation of the heat insulating envelope.

Also, to describe the installation of the outer enclosure as shown in FIGS. 5 and 6, a construction board 4 is placed on the structural material 3, and the peak part 4b of the construction board 4 is The peaks 4b of the construction boards A are overlapped, and then the fixing tool A of the present invention is inserted while rotating from the appropriate position at the top of the overlapped location of the peaks 4b, 4b of the construction boards 4, 4, and the drill part 1a is used to tighten the structure. A through hole is drilled in the material 3, the guide piece 1e hits the top surface of the structural material 3 and breaks off, and by further rotation, the right-hand threaded portion 1b is screwed into the structural material 3, and at this time, the polymerization occurs. As shown in FIG. 5, the ridge 4b on the lower side of the location is tilted and deformed, but when it rotates further, the ridge 4b rises due to the action of the upper right-hand threaded portion 1d, and the ridge of the outer building board 4 4b, and at the same time, the left-hand threaded portion 1c bites into the already formed thread of the structural member 3, and rotation stops and tightening becomes impossible, completing the installation of the outer envelope.

[Effect of idea]

In the present invention, a drill portion 1 is provided at the lower end of the shaft portion 1.
a, a right-handed threaded portion 1b is screwed above this, and a guide piece 1 is provided on the circumference of the shaft portion 1 intermediate the right-handed threaded portion 1b and the drill portion 1a, and is detachable with an appropriate force.
e, a left-hand threaded portion 1c is threaded substantially continuously above the right-hand threaded portion 1b, and an upper right-hand threaded portion 1d is threaded onto the upper portion of the shaft portion 1. , by using this fixture A, the first
A heat insulating envelope such as a double roof or wall is installed in which a relatively elastic heat insulating material 5 is sandwiched between the inner building board 4 and the outer building board 4. However, even if these are tightened at once from the outside side, the fixing device A becomes unable to rotate at a certain height (depth) or interval, and the building board 4 on the outside side does not dent, causing the appearance to deteriorate. can be made elegant, and in turn can have good heat insulation performance.Secondly, the mountain portion 4b of the outer enclosure
It is possible to prevent the slope deformation of the peak portion 4b below the overlapped portion of the heat insulating material 5, and thirdly, the insulation material 5 can be penetrated very efficiently.

To explain these effects in detail, first, even if they are tightened at once from the outside with the fixing tool A so as to sandwich the heat insulating material 5, which has relatively elasticity, the right-hand threaded portion 1b will not attach to the structural material 3. It rotates while biting in, but when the left-hand threaded part 1c, which is substantially continuous with the right-hand threaded part 1b, starts to bite into the structural material 3, the left-hand threaded part 1c acts to remove all the threads that have already been formed. None, with this kind of reaction force, fixing device A
The rotation of the board 4 stops, and even a person without any skill can no longer dent or distort the outer building board 4, and the mounting part becomes flat.
It has the advantage of being tidy and having a good appearance.

In addition, in the past, the insulation material 5 in the dented area was tightened.
As the thickness becomes thinner, this becomes a cold bridge point and deteriorates the insulation performance. However, by using the fixing device A of the present invention, there will be no dents like this, and good insulation can be achieved at any location. performance.

In this way, it has an extremely simple structure in which the left-hand threaded portion 1c is simply screwed into a fixing tool called a general drill screw, and it has a stop mechanism, and its handling is as simple and quick as before. It can be provided at low cost.

In addition, since the upper right-hand threaded portion 1d is provided, the peak portion 4b of the building board 4 (lower position) on the inner surface side of the overlapping location
is tilted and deformed as shown in FIG. 5, but when it is rotated further, the peak part 4b of the inner building board 4 acts as if it were a nut that does not rotate due to the rotational action of the upper right-hand screw part 1d. As shown in FIG. 6, the sloped and deformed ridges 4b rise and come into close contact with the ridges 4b of the outer building board 4, allowing for extremely orderly roofing and ensuring watertightness at the fixed points. Can be done well. Further, even if the periphery of the fixing tool A at the attachment point of the building board 4 on the outer surface side of the heat insulating envelope is recessed as shown in FIG. 4, the roofing can be done in a flat and orderly manner in the same manner as described above.

In this way, with the present invention, the height (depth) or spacing can be regulated by the anti-rotation action of the left-hand threaded portion 1c, and the synergistic effect is that deformation and denting can be prevented by the upper right-hand threaded portion 1d. As a result, extremely orderly roofs, walls, etc. can be constructed even with thin architectural boards 4.

Furthermore, if the heat insulating material 5 is made of a relatively hard material such as rock wool, it would normally be difficult to insert any type of fastener, but the fastener A of the present invention has the following features: Right thread part 1b and drill part 1a
A guide piece 1e, which can be broken off with an appropriate force, is provided protrudingly on the circumference of the shaft part 1, which is intermediate between the two. The insulation material 5 can be inserted while stirring,
This has the effect of making it extremely efficient to penetrate the heat insulating material 5.
