Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a wind-resistant tile that prevents a wind-up due to a strong wind such as a typhoon.
[0002]
[Prior art]
Conventionally, as a means to prevent the tile from blowing up due to strong wind blowing, it is fixed by nailed to a horizontal pier through a nail hole provided near the bottom of the tile, or a metal wire is stretched around the roof periphery, Construction such as fixing to the ground was done. Many improved methods that can omit this nailing and fixing method have also been proposed.
[0003]
For example, as shown in FIG. 6, when the bottom hook 13 of the lower roof tile 12 is brought into contact with the horizontal pier 11 on the rafter and then the upper roof tile 15 is placed on the top roof 15, The fixing bracket 16 is fixed to the pier 11 in advance, and the distal end bent portion 16a is rolled up in a state where it is inserted into the insertion portion 14 provided in the butt hook portion 13. (See Patent Document 1)
[0004]
Thus, since the distal end bent portion 16a of the fixing bracket 16 is inserted into the insertion portion 14 provided in the buttocks hook portion 13, the roof tile can be effectively prevented from being blown up by a strong wind or the like. However, in this conventional lifting method, there is a problem in reliability, for example, it takes time to attach a new fixing bracket 16 by nailing and the wind resistance effect is lost when the roof tiles are displaced up and down. In addition, although there is a thing with the crosspiece itself made of metal (refer to Patent Document 2), the principle of blowing up the roof tile is substantially the same as that of Patent Document 1.

And at least a part of the opening edge portion of the crosspiece member is cut out, and the engaging thick portion at the tip of the wind-proof tile retaining protrusion can be inserted into the groove portion from the cutout portion. In addition, the present invention is characterized in that, after the insertion, it is shifted in the lateral direction from the notched opening edge portion along the groove portion so that the opening edge portion of the crosspiece member can be locked in a retaining state. The wind-resistant roof tile according to the first invention of the present invention Can.
[0008]
[0009]
Furthermore, in the wind-resistant roof tile of the present invention, the wind-resistant roof tile is provided with a hook-shaped protrusion having a hook-like shape formed on the top of the bottom portion thereof, and the engagement back portion is provided on the back surface on the head side. When the hook-shaped projection and the engagement insertion portion are rolled with the wind-resistant roof tile, the engagement difference between the roof tiles of the tile-shaped projections of the roof tiles that are to be rolled down and the tiles of the tiles that are to be scratched upwards. More preferably, the embodiment is embodied in a form in which the upper roof tiles are inserted into the insertion portion and are engaged with each other so that the lower roof tiles are held downward.
[0010]
The above-mentioned problem is the method of hoisting the wind-resistant tile according to the first aspect of the invention, wherein the wind-resistant tile is removed from an opening edge portion in which a part of the crosspiece member having a groove portion prepared in advance as a roof base is cut out. After the engaging thickened portion of the retaining protrusion is inserted into the groove, the entire wind-resistant roof tile is shifted laterally along the groove from the notched opening edge and pulled out to the opening edge of the crosspiece member. The problem can also be solved by the wind-up tile roofing method according to the second aspect of the present invention, which is arranged in a stopped state.
[0011]
Further, in the wind-up method of the wind-resistant tile according to the first invention, the wind-resistant tile is prevented from being removed from an opening edge portion in which a part of the crosspiece member having a groove portion prepared in advance as a roof base is cut out. After the engaging thick part of the protrusion is inserted into the groove, the entire wind-resistant roof tile is laterally shifted from the notched opening edge along the groove , and is prevented from being removed from the opening edge of the crosspiece member. When the wind-resistant roof tile located on the upper side is rolled, the tip flange of the hook-shaped projection of the roof tile placed on the lower side is inserted into the engagement insertion portion of the roof tile placed on the upper side. Thus, the wind-up method of the wind-resistant tile according to the present invention, which is arranged in such a positional relationship that the upper tile is blown up so that the lower tile is held downward, can be solved.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Next, 1st, 2nd embodiment which concerns on the wind-resistant roof tile of this invention and its hoisting method is described, referring FIGS.
[0013]
(First embodiment)
First, the wind-resistant roof tile of the present invention is a clay roof tile provided with an underlap portion 21 and an overlap portion 22 on the left and right sides of the flat plate portion 23 as illustrated in FIG. The rear surface is provided with retaining protrusions 3 and 3 projecting downward (in FIG. 1, drawn in a shape projecting upward from the drafting convention). In the present invention, it is necessary to project at least one of the retaining projections 3.
[0014]
As shown in FIGS. 2 and 3, the retaining projections 3 and 3 are formed in the groove portion of the crosspiece member 4 that has a groove portion 41 that opens upward and has opening edge portions 42 and 42 narrower than the inside. 41 is formed so as to be able to run in the inserted state.
[0015]
Specifically, a portion 43 is formed by notching a part of the horizontal beam member 4 having such a groove 41 and exposing the inside, and first, as shown in FIG. If the retaining protrusion 3 is inserted, and then pushed inward as shown in (B), and further shifted in either the left or right direction as shown in (C), the tip of this retaining protrusion 3 The portion 31 is accommodated in the groove portion 41 in a state of being drawn between the opening edge portions 42 and 42.
[0016]
And in this invention, since the front-end | tip part 31 of this retaining projection part 3 is formed thickly and it is set as the engagement thick part 31a, it is in the retaining state in the opening edge parts 42 and 42 of the said horizontal crosspiece member 4. Even if the roof tiles are locked and blown by a strong wind, it is possible to effectively prevent vertical displacement as well as blowing up. In the case where a plurality of retaining protrusions 3 are provided so as to protrude, the engaging thick part 31a may be formed at least on one of them, and need not be formed on all of them. Further, as shown in FIG. 3, the engaging thick part 31a is formed on both sides of the distal end portion 31 of the retaining projection part 3, but it is only required to be formed on at least one side.
[0017]
Furthermore, since the position of the roof tiles is automatically determined depending on the position of the prefabricated horizontal beam member 4, it does not require any skill in lifting up, and the finished appearance is neatly arranged. Further, it is only necessary to fit the retaining projection 3 to the crosspiece member 4, and the conventional fixing nailing work is not necessary, which is effective in reducing the work man-hours and costs.
[0018]
Next, the wind-up method for wind-resistant tiles according to the present invention having the above-described configuration will be described. The outline of the procedure has already been described above, and the following procedure is characterized.
1) The crosspiece member 4 having the groove 41 as a roof base is previously disposed and prepared on a rafter or a field board (not shown). 2) Next, the tip end portion 31 having the engagement thick portion 31a of the retaining projection 3 of the wind-resistant roof tile is inserted into the groove portion 41 from a portion 43 where a part of the crosspiece member 4 is cut out. 3) Thereafter, the entire wind-resistant roof tile is shifted in the horizontal direction from the cutout portion 43 and disposed in the retaining state at the opening edge 42 of the crosspiece member 4.
In addition, in the figure, although the flat roof tile is illustrated, this invention is not limited to this.
[0019]
In the wind-resistant roof tile of the present invention, it is preferable to apply a long molding material made of a synthetic resin or aluminum alloy extruded material having a sufficient strength or a stainless steel plate bending material as the cross beam member 4. And soft materials are inappropriate. The synthetic resin referred to in the present invention is a term that includes a synthetic resin material in which an inorganic or organic filler (filler) is blended, and includes, for example, synthetic wood obtained by blending wood powder into a resin. is there.
[0020]
The portion 43 where at least a part of the opening edge of the crosspiece member 4 is notched is dimensioned so that the distal end portion 31 of the retaining projection 3 can be inserted into the groove, and is arranged at an appropriate interval. It is good to leave.
[0021]
Further, as the crosspiece member 4 used in the present invention, instead of the one opening edge 42 and the wall 43 notched as shown in FIG. 3, the opening edges on both sides of the opening as shown in FIG. What provided the notch part 44 which notched the parts 42 and 42 may be used. In this case, when the retaining protrusion 3 is fitted, only insertion and lateral movement are required, and there is an advantage that the mechanical strength of the crosspiece member 4 is not relatively lowered.
[0022]
Further, as the crosspiece member 4 used in the present invention, instead of the one opening edge portion 42 and the wall portion 43 as shown in FIG. 3, the opening edges on both sides of the opening as shown in FIG. A portion provided with a notch portion 45 in which one of the portions 42 and 42 is notched may be provided.
[0023]
In the case of the cutout portion 45, as shown in FIGS. 8 (A) and 8 (B), the tip end portion 31 of the windproof roof tile retaining projection portion 3 is inserted into the groove portion 41 therefrom. Next, the windproof roof tile is shifted in the horizontal direction while drawing the leading end portion 31 between the opening edge portions 42, 42 on both sides, thereby opening the edge portion 42 of the crosspiece member 4 as shown in FIG. The engaging thick part 31a of the distal end portion 31 is engaged with the front end portion 31 and can be arranged in a retaining state.
[0024]
In this case, when fitting the retaining protrusions 3, insertion and lateral movement are sufficient as in the case of FIG. 4, and there is an advantage that the mechanical strength of the crosspiece member 4 is not further reduced. In the example of FIG. 4, depending on the arrangement of a large number of cutout portions 44, the scoring protrusion 3 of the wind-resistant roof tile that has been rolled up coincides with another cutout portion 44 by chance, Although it is expected that there is a problem that the retaining state cannot be obtained, in the case of FIGS. 7 and 8, there is an advantage that such a situation does not occur. This is the same in the case of FIG.
[0025]
(Second Embodiment)
Next, a second embodiment of the present invention will be described.
The wind-resistant roof tile of the second embodiment is provided with the retaining projection 3 described in the first embodiment described above, and further has a tip on the top surface of the bottom portion 24 of the roof tile as shown in FIG. Is provided with a hook-like protrusion 5 (see (B) and (C) of FIG. 1), and an engagement insertion portion 6 is provided on the back surface on the head 25 side.
[0026]
And the hook-shaped projection part 5 and the engagement insertion part 6 are formed in the following positional relationships. That is, when the wind-resistant roof tile is rolled, as shown in FIG. 5 (A), the leading edge portion 5a of the hook-shaped projection portion 5 of the roof tile 2a to be wound downward is the top of the roof tile 2b to be wound upward. It is inserted in the engagement insertion part 6, and is arrange | positioned in the positional relationship which engages so that the lower roof tile 2a may hold down the blowing of the upper roof tile 2b below. For this purpose, it is most preferable in terms of production technology that the engagement insertion portion 6 is set on the back surface of the bent base portion 22a of the overlap portion 22, as shown in FIG.
[0027]
And the wind-resistant roof tile specifically comprised in this way can be lifted up with the following raising method. That is, first, similarly to the case of the first embodiment, the crosspiece member 4 having a groove portion prepared in advance as a roof base and the retaining projections 3 and 3 of the wind-resistant tile are fitted and arranged in a retaining state. However, at the same time, when the wind-resistant roof tile 2b located on the upper side is rolled, the engagement of the roof tile 2b of the roof-shaped projection 5 of the roof tile 2a wound on the lower side is pushed up. It is possible to adopt a rolling-up method in which the upper roof tile 2b is engaged so that the lower roof tile 2b is pulled down by being inserted into the joint insertion portion 6.
[0028]
The wind-resistant roof tile and its lifting method as in the second embodiment can enjoy the advantages of the first embodiment as described above, and the hook-like projections 5 of the lower roof tile 2a can be connected to the upper roof tile 2b. Since the lower roof tile 2a pulls the head side of the upper roof tile 2b and suppresses the wind-up by inserting and engaging with the insertion part 6, the wind resistance performance of the entire wind-resistant roof tile is improved. The advantage is obtained.
[0029]
As the position where the engagement insertion portion 6 is provided, in addition to the back surface of the bent base portion 22a of the overlap portion 22 shown in FIG. 1 (D), as shown in FIG. Although it can be assumed to be provided at the end, it can be said that it is a sub-optimal method because it can be easily blown from the overlap side by a strong wind as compared with the case where it is provided on the overlap side.
[0030]
As described above, the wind-resistant tile of the present invention has been described mainly from the viewpoint of preventing blowing-up in strong winds, but the present invention is not only excellent in wind-resistant performance, but the raised tile is also the foundation for vibrations in the event of an earthquake. Because it is strongly integrated with the material, it does not cause misalignment or fall off. As described above, the present invention can provide a wind-resistant roof tile that can exhibit excellent performance in both wind resistance and earthquake resistance, and a method for lifting it.
[0031]
【The invention's effect】
Since the wind-resistant roof tile and the method of raising the wind of the present invention are configured as described above, a reliable wind-resistant effect can be expected without adding new members and processes to the conventional lifting work. Fixed nailing can be omitted. In addition, the cost of roofing work can be reduced, and the durability of the finished roof is greatly improved. Therefore, the present invention has an extremely large industrial value as a wind-resistant roof tile and a method for lifting it that have solved the conventional problems.
