Description

[Detailed description of the invention] (Industrial application field) This invention can be used for roofing panels for greenhouses, carports, eaves,
The present invention relates to a face plate fixture that is fixed to other mounting locations.

(Prior Art) When attaching a face plate, such as a corrugated plate made of synthetic resin, to a main building material, etc., hook bolts have generally been used. However, in order to attach the face plate using hook bolts, it is necessary to rotate the nuts of the core bolts, which takes time and effort, and depending on the tightening condition, it may loosen too much and come off, or it may loosen too much and cause damage. Especially in the case of corrugated sheets made of synthetic resin, which has a large coefficient of thermal expansion, dimensional fluctuations due to changes in temperature are more severe than expected, and even if the tightening of the hook bolts is not optimal during construction. Even if there is a change in temperature, an abnormally large force is applied to the hook bolt attachment part, leading to damage to the corrugated plate.

Therefore, a fixing tool that eliminates the above-mentioned drawbacks is disclosed in, for example, Japanese Utility Model Application Laid-open No. 55-145616. This fixing tool has one end curved in an arc shape, and the tip of the curved part is applied from the lower edge of one side of the purlin material, for example, a square crosspiece, and the curved part and the square crosspiece are fitted and fixed using elasticity. be.

(Problem to be solved by the invention) However, if the curved portion and the square crosspiece are simply fitted and fixed as described above, temporary negative pressure will be applied to the outer surface of the face plate during typhoons, etc., and this will be repeated. The fixing device may come off the crosspiece. Also,
In the curved part, since the gripping and fixing is done by point contact at the corner of the square crosspiece, the bonding force between the crosspiece and the fixture is weak, and it is easy to come off in the first place. Because it protrudes, it is easy for other objects to get caught on this tip, and if it gets caught, a downward force is applied, and the direction of this force is in the direction that the fixing device comes off, so it has the disadvantage that it can easily come off. Ta.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a fixture for a face plate that is easy to install, securely fixes the face plate to the square, and will not be damaged or come off due to temperature changes or typhoons.

(Means for Solving the Problems) In order to achieve this object, the present invention comprises a washer, and a hook made of spring material that is coupled to a square crosspiece, and the hook has a washer engaging head at one end. In addition, from the washer engaging head to the other end, the washer has a linear part, an elastic arc part, a hook part and a protruding part that are approximately shaped and come into close contact with three sides of the square crosspiece, and each of the above parts is on the same plane. A means for solving the above problem is provided by a face plate fixture, characterized in that the elastic arcuate portion and the protruding portion each protrude outwardly with the hook portion interposed therebetween.

(Function) Fluctuations in negative pressure during a typhoon cause repeated loads in the vertical direction to act on the surface of the face plate. At this time, a tensile force and an almost no-load state are applied to the fixture alternately. Furthermore, when the face plate expands and contracts due to changes in temperature, forces act from all directions orthogonal to the fixture.

Here, if the fixture is fixed without any deformation, the above force will not be absorbed and a reaction will act on the face plate, resulting in deformation of the face plate itself. If the face plate is a corrugated plate, forces acting in the direction of successive waves will change the height of the waves, and forces acting in a direction parallel to the waves will result in either tensile or compressive deformation.

The pressure during these deformations concentrates on the fixing hole in the face plate, which is the contact area with the fixing tool, and may even cause cracks around this hole.

According to the face plate fixing device of the present invention having the above structure, the entire body is made of spring material, and because of the presence of the circular arc portion, all that is required is to place the protruding portion against one corner of the square crosspiece and push the hook portion from the circular arc portion side. The hooks fit tightly into the three sides of the square crosspiece, making it easy to attach the face plate.

When the face plate attached in this way expands or contracts due to temperature changes, for example, the arcuate portion of the fixture absorbs and disperses the force caused by the expansion or contraction, preventing damage to the face plate. The strong elasticity of the hook portion ensures that the square crosspiece can be gripped as usual, and the hook portion will not come off the square crosspiece even if the arcuate portion is deformed.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

Fig. 1 is a side view showing an embodiment of the fixing device of the present invention, Fig. 2 is a partial side cross section showing how the corrugated plate is fixed by the fixing device, Fig. 3 is a perspective view of the same, and Fig. 4 is the same fixing. FIG. 5 is a perspective view of the washer used in the tool, and FIG. 5 is a perspective view of the same packing.

In the figure, 1 is a washer, 2 is a hook made of spring material (wire material such as stainless steel spring steel with a thickness of about 0.5 to 5 mmφ), 3 is a packing, 9 is a square crosspiece, and 10 is a wave shape made of synthetic resin. This is the face plate.

The washer 1 is curved in one diameter direction from the center hole so as to follow the wave shape of the face plate 10.

The hook 2 has a head 4 at one end of a straight portion 5, and an elastic circular arc portion 6 that is bent into an arc is formed following the straight portion 5, and the lower end of the circular portion 6 is connected to the straight portion 5. A straight portion 7-1 is formed on a substantially extended line of the straight portion 7-1. Further, a horizontal portion 7- which is orthogonal to this straight portion 7-1
2 is bent and the end of the horizontal portion 7-2 is further raised to form a rising portion 7-3. That is, the straight portion 7-1, the horizontal portion 7-2, and the rising portion 7-3 constitute a hook portion 7 that is shaped to be in close contact with a portion of three side surfaces of the square crosspiece 9. A protruding part 8 is formed from the upper end of the rising part 7-3, and is curved and protrudes downward from the horizontal. These arcuate portions 6, hook portions 7, and protrusion portions 8 are all on the same plane.

In such a configuration, the face plate fixture of the present invention has the following features:
A wave-shaped face plate 10 placed on a square crosspiece 9 is placed on the face plate 10, and the upper end head 4 of the straight part 5 of the hook 2, the washer 1, and the packing 3 are positioned, and the protruding part of the hook 2 is placed on the face plate 10. 8 to one corner of the lower part of the square crosspiece 9, and push it in from the rear to fix it as shown in FIG. That is, the hook part 7 is bent into a substantially shape through the elastic arc part 6 which is bent and protrudes outward (to the left in the figure) from the rear side surface of the square crosspiece 9 below the straight part 5. It is hooked from the rear side of 9 to the front side via the bottom side. . In this case, the face plate 10
A hole is drilled in the hole for the hook 2 to pass through, and a washer 1 and a gasket 3 are inserted into this hole from the top surface of the face plate 10.
A hook 2 equipped with a is inserted, the hole is sealed with a gasket 3, and the top is pressed with a washer 1 and a head 4. In addition, as the square crosspiece 9, C-shaped channel material, channel steel, square pipe, etc. are used. An arc-shaped elastic circular arc portion 6 bent rearward and laterally between the shaped hook portion 7 and the linear portion 5 acts to strongly elastically engage the hook portion 7 with the lower surface and front and rear side surfaces of the square crosspiece 9. has.

Furthermore, the presence of the elastic arc portion 6 absorbs forces in various directions caused by expansion and contraction of the face plate 10 due to changes in temperature, allowing deformation of the face plate 10 to some extent and preventing damage to the face plate. This also prevents the fixture from coming off the square crosspiece 9 due to the presence of the hook part 7. The one-dot chain line in FIG. 2 shows an example of the function of the circular arc portion 6. When the outside air rises and force acts in the direction of expanding the face plate (corrugated plate) 10 and increasing the wave height, the hook The circular arc portion 6 of No. 2 is elastically deformed in the direction of arrow A, allowing the change in the wave height. Also, when a force in a direction parallel to the waves is applied to the fixture, for example, the arc portion 6 changes elastically,
A portion of the washer 1 is movable in the direction of arrow B.

Furthermore, even if another object is caught on the protruding part 8 from above, the protruding part 8 is curved downward, so that it will not slide off and a large force will not be applied to the hook part 7 to remove it from the square crosspiece 9. Even if an object is caught on the protrusion 8 from below, there will be no problem since the force from below is in the direction of locking the hook 7 to the square crosspiece 9. Furthermore, since the hook portion 7 is shaped, the contact surface with the square crosspiece 9 is increased, and stable locking can be achieved. In addition,
In the drawing, since the face plate 10 is a corrugated plate, the washers and the packing are curved along the waveform, but if the face plate is a flat plate, the washers and the packing are also flat.

(Effects of the invention) As explained in detail above, according to the invention, since the roughly shaped hook part and the elastic arc part bent rearward and laterally are formed, the hook part has a strong elastic force on the square crosspiece. There is no risk that the hook part will come off the square crosspiece when it is engaged and caught on another object, and even if external force due to negative pressure or expansion/contraction is applied to the outer surface of the face plate, the circular arc Since this is elastically absorbed by the hook, the face plate will not be damaged and the hook will not come off the square crosspiece.
