JP2013104265A - Fixture for batten seam roof - Google Patents

Abstract

PROBLEM TO BE SOLVED: To facilitate fitting and obtain sufficient fixing force by solving various problems when a waterproof sheet is fixed to a roof with batten seams, for example, a problem that the waterproof sheet and a fixing plate are bonded (as well as fusion bonding) and the sheet is hardly considered to peel there, but the screwed fixing plate may fall, namely, how hard to blow the sheet depends upon the fixing force of screws 56 to a cover material 53, including the contradiction that while large force is needed to widen and fit the cover material when the cover material is made thick and work becomes difficult, the fixing force with the fixing plate decreases when the cover material is made thin.SOLUTION: The fixture is used while extending across two riser parts of metal plates of a roof with batten seams, and comprises an outer member which has side face parts folded at both ends of a plane part to be sectioned substantially in a channel shape, and also has folded-back parts at both ends of the side face parts, and a reinforcing inner material used while inserted into the outer member.

Description

  The present invention relates to a roof tile roof fixture.

  Blasting is one method of using a metal plate to cover a roof. It is common to strike a beam on the back plate at regular intervals in the direction of the flow of the roof, lay a metal plate on the back plate, and cover the metal plate on the beam. This pier is called a wand.

  Compared to a flat roof that does not use a rod, the expansion and contraction of the metal plate due to temperature changes can be absorbed between the rods. Further, if the distance is set to a dimension equal to or less than the width of the metal plate, the joint in the flow direction of the metal plate is eliminated, and the rain finish is excellent.

When fixing a tarpaulin to the roof of this tiled bar, in general, in order to flatten the whole, a heat insulating material (foamed plastic board) is fitted (laid) on the part other than the tiled bar, and the tiled bar part does not protrude. Like that.
Then, a plastic sheet such as vinyl chloride is placed on the whole and firmly fixed. In order to prevent the plastic sheet from flying even in a typhoon, it must be fixed with a certain level of strength.

The fixing method is to cover and fix the cover plate on the rising part of the groove plate from above, and fix the cover material and the fixing plate (usually a circular one coated with a solvent that dissolves the plastic sheet) with screws. In general, the fixing plate and the plastic sheet are bonded (fused).
Referring to FIG. 5, the rising portions 52 of the groove plate 51 face each other to form a goby portion. Among these facing parts, there are things that have a hanger and a cap, and things that have wood in it. The cover material 53 is placed over the rising parts facing each other. The cover member 53 is fixed by a restoring force in the arrow direction 54 of the cover member 53. In other words, when fitting, it is necessary to overcome the restoring force and spread the cover material 53 to cover the rising portion 52.

  A fixing plate 55 is placed on the cover material 53 and fixed with screws 56 from above. For this reason, the fixing plate 55 is usually provided with a hole through which a screw passes in advance. The screw 56 is called a drill screw, and the tip part is a drill for making a hole in a metal. Nut is not used. The fixing plate 55 is generally laminated with the same plastic sheet. Then, a plastic sheet 57 is laid on the entire upper surface and fixed to the fixing plate 55. For fixing the plastic sheet 57 and the fixing plate 55, there are a method in which the plastic sheet is melted with a solvent, a method in which the plastic sheet is applied with heat or high frequency, a method in which the plastic sheet is attached with a hot melt adhesive, and the like.

  At this time, the plastic sheet and the fixing plate are bonded (fused together), and it is unlikely that the plastic sheet is peeled off at this portion, and the sheet is peeled off because the fixing plate fixed with screws is removed. That is, the difficulty of being blown off is the fixing force of the screw 56 to the cover material 53.

  In such a conventional material, when the cover material is made thick, a large force is required when the cover material is expanded and fitted, and the work becomes difficult, and when the cover material is made thin, the fixing force with the fixing plate is reduced. Therefore, it has been desired to be easily fitted and have a sufficient fixing force.

  In view of the above situation, the present inventor has completed the waterproof sheet fixing lower material of the present invention as a result of earnest research, and the feature thereof is that two of the metal plates on the roof of the roof tile roof. An external part having a side part that is bent at both ends of the flat part so that the cross section is substantially U-shaped, and has a folded part that is bent at both ends of the side part. It is in the point comprised from the material and the reinforcement inner material used by inserting inside the outer member.

  The two rising portions of the metal plate are usually portions where the rising portions of the metal plate called groove plates are adjacent.

The outer member of the present invention may be the same as the above-described general cover member, and has a bent shape with a U-shaped cross section. That is, it is composed of one plane part, two side parts, and two folded parts. The folding part does not have to be strictly folded as long as the functions described later can be achieved. A thing that can be swollen and locked even if it is not bent, a curved part, or the like may be used.
The material may be normal, stainless steel, tinplate, or other metal plate.

  The angle between the flat surface portion and the side surface portion in the outer member of the present invention is preferably 75 degrees to 85 degrees. This is because it is difficult to fit at 75 degrees or less, and it is easy to come off at 85 degrees or more. The length of the side surface portion (distance from the flat surface portion to the folded portion) is 15 to 30 mm, preferably 18 to 25 mm.

  The length of the outer member is free and is usually about 5 to 20 cm, but there is no problem even if it is longer depending on the crosspiece (rise portion) of the rod. However, if it is too long, it will be difficult to fit. A hole through which the fixing screw passes is provided.

  What is necessary is just to select the width | variety of an external material suitably with the width | variety of the standing | starting-up part of a rod (the width of a goby). According to the inventor's experiment, three types of widths of 50 mm, 60 mm, and 72 mm were applicable to most of Japan.

The flat part of the external material may be laminated with the same plastic as the waterproof sheet on the surface. The thickness of the laminate is about 0.1 to 0.7 mm.
Further, a solvent may be applied.

  The tip of the side part of the external material is a folded part, and the angle of folding is free and may be caught by the rising part. Usually, it is about 20 to 60 degrees. Although the length of this folding | turning part is also free and should just be caught, it is about 5-15 mm normally.

  As described above, the outer member is preferably thicker from the viewpoint of strength (fixing strength of the fixing plate), and thinner from the viewpoint of easy fitting. Usually, strength is not obtained at a thickness of 0.5 mm, and it is difficult to fit at a thickness of 0.8 mm. However, in this invention, since intensity | strength is ensured with the reinforcement inner material mentioned later, it may be thin. Therefore, 0.8 mm or less is sufficient, and further 0.5 mm or less may be used. However, it is not limited to them.

The reinforcing inner material inserted and used inside the outer member described above is the first point of the present invention, whereby the fixing strength is improved.
The reinforcing inner material may be a simple plate or may have a U-shaped cross section (shape like a channel). The thickness is a problem of strength, but is preferably 0.5 to 1.2 mm, more preferably 0.8 to 1.0 mm. The material may be a metal like the outer member.

  The fixing strength of the external material is whether or not the screw can be removed from the external member, and is the ease of deformation of the screw hole. As described above, this is due to the thickness of the outer member. In the present invention, since there is a reinforcing inner material that is positioned below the outer member and is fixed through with the same screw, the screw must be removed from both the outer member and the reinforcing inner material to be removed. In terms of strength, the total thickness of the outer member and the reinforcing inner material corresponds to the thickness of the conventional one (of course, one piece).

  Therefore, the thickness of the reinforcing inner material is not particularly limited, but is about 0.5 to 1.2 mm, preferably 0.8 to 1.0 mm.

As described above, this reinforcing inner material is also preferably U-shaped in cross section (preferably an angle of 80 to 95 degrees). When the U-shape is formed in this manner, the outer member is spread when inserted into the inner side and the lower side (tip side) of the outer member. When the external material is spread out, it becomes easy to fit the rising part of the external member.
The size of the reinforcing inner material can be inserted into the outer member, and is preferably smaller than the planar portion of the outer member and larger than the planar size formed by the tip portion of the side surface portion.

  The reinforcing inner member is preferably inserted in advance into the outer member, but instead of being inserted into the outer member, the reinforcing inner member may be placed on the tile rod in the field and the outer member may be fitted thereon.

  The present invention is a waterproof sheet fixing lower material, in the roof to be used, whether there is a cap on the goby portion, whether the goze portion is filled with plastic heat insulating material or wood, etc. It is irrelevant whether it is put. It is a fixing tool for fixing the surface sheet, and there may or may not be others.

The present invention has the following effects.
(1) Since the reinforcing inner material is present, the fixing strength is increased even if the outer member is thin.
(2) Since the external material can be made thin, it is easy to fit.
(3) When the side surface portion of the outer member is expanded by the reinforcing inner material, the fitting is easier.
(4) When the reinforcing inner material has a U-shape, the side surface portion is more easily spread and the expanded state is stabilized until it is fitted.

It is a perspective view which shows one example of the lower material for fixing the waterproof sheet of the present invention. It is a perspective view which shows the other example of this invention waterproof sheet fixing lower material. It is sectional drawing which shows the use condition of this invention waterproof sheet fixing lower material. It is sectional drawing which shows the use condition of this invention waterproof sheet fixing lower material. It is sectional drawing which shows a prior art example.

Hereinafter, the present invention will be described in more detail with reference to embodiments shown in the drawings.
FIG. 1 is a perspective view showing an example of the lower sheet 1 for fixing a waterproof sheet according to the present invention, which includes an outer member 2 and a reinforcing inner member 3. The outer member 2 in this example includes a flat surface portion 4, a side surface portion 5, and a folded portion 6.
The reinforcing inner material 3 is a rectangular plate, and the length L1 in the width direction is slightly shorter than the width L2 of the flat portion 4 and longer than the tip separation distance L3 of the side portion. Thus, if it becomes longer than L3, the separation distance of a side part (folding part) will be enlarged, and it will become easy to fit in the gob part (rise part) of a brick rod.

FIG. 2 is the same as FIG. 1 except that the reinforcing inner member 3 is formed in a U-shape on the side surface, and is more easily fixed at the lower position. That is, it is easy to spread and fix the side surface portion outward.

FIG. 3 shows an example in which the example of FIG. 2 is used as in the conventional example of FIG. In this state, it is not yet fitted, and it can be seen that the side surface portion of the outer member is opened and can be easily fitted. FIG. 4 shows a state where the waterproof sheet fixing lower material is fitted, the fixing plate 55 is placed and tightened with the screws 56, and the plastic sheet is placed thereon, proceeding from FIG.

Next, the strength of the base material for fixing the waterproof sheet of the present invention in the above example was examined. The results are shown in Table 1. The experiment was performed by changing the thickness of the outer member and the thickness of the reinforcing inner material. First, the fixed load is a necessary force when the outer member is fitted into the rising portion, and indicates that the larger the value is, the harder the fitting is. The anchor pull-out load is a necessary force for pulling out the screw. The presence or absence of deformation at 10 kN is the presence or absence of deformation of the outer member when the screw is pulled with a force of 10 kN.

  From Table 1, all the screws were not removed at 10 kN, so there is no problem in these examples. However, from the presence or absence of deformation at 10 kN and the ease of fitting, the outer member thickness 0.5 mm, the combination of the reinforcing inner material thickness 1.0 mm, or the outer member thickness 0.8 mm, the reinforcing inner material thickness 0.8, Or a combination of 1.0 mm seems most suitable.
