Description

  The present invention relates to a saddle for corrugated slate refurbishment, and more particularly to a saddle used for refurbishing corrugated slate provided as a roofing material or an outer wall material to support a new exterior material.

  Corrugated slate as an exterior material is widely used on the roofs and outer walls of buildings such as factories and warehouses. For example, a corrugated slate used as a roofing material is placed on the upper surface of a purlin girder constituting a roof via a laying member, and hook bolts that are hooked on the purlin girder at predetermined intervals are the slate. These are supported and fixed by screwing nuts into male screw portions that extend upward through the tops.

  The roof covered with the corrugated slate is appropriately repaired by being damaged or deteriorated over time. As a conventional means for repairing the roof, the corrugated slate to be replaced is superposed and adjacent to the corrugated slate. Remove all hook bolts supporting other corrugated slate from the purlin, remove the corrugated slate to be replaced, and install a new corrugated slate. And, by opening a through hole for inserting a hook bolt in an appropriate place of a new waveform slate, and hooking the nut after engaging the lower part of the hook bolt inserted into the through hole on the purlin girder The new waveform slate is supported and fixed. However, in this means, there is a problem that a part of the old slate that is damaged or dust when removing the slate falls into the building from between each of the main purlins and soils the floor surface. Further, as described above, it is pointed out that the new slate requires a lot of manpower and construction costs because it takes time to newly open a through hole for inserting the hook bolt.

  Therefore, as a means for solving this problem, for example, there is a “double thatched roof structure” shown in Patent Document 1. In the roof structure of this patent document 1, as shown in FIG. 6, the flat part 14 which provided the through-hole part 12 which accept | permitted insertion of the hook volt | bolt 10 latched to the main house girder 32, and this flat part 14 of A saddle 19 comprising skirt portions 16 extending from both sides is used. Then, after inserting the male screw portion 10 a provided on the upper portion of the hook bolt 10 into the through-hole portion 12 of the saddle 19, the saddle 19 is straddled over the angled portion 18 a of the corrugated slate 18. The composite bolt 20 having a female screw portion 20a formed therein and a male screw portion 20b formed outside is screwed into the male screw portion 10a of the hook bolt 10 protruding upward from the saddle 19. The saddle 19 is fixed in a state where the lower edge 16 a of each skirt portion 16 of the saddle 19 is in contact with the corrugated slate 18. Then, a new metal roof material 22 is disposed from above the composite bolt 20, and a nut 28 is attached to a portion where the composite bolt 20 protrudes from a through hole 22 a provided in the metal roof material 22 via a packing 24 and a washer 26. By screwing, the new metal roof material 22 is fixed to the upper surface of the corrugated slate 18 so as not to fall off.

According to the double-strung structure of Patent Document 1, since the existing hook bolt 10 is used, there is no need to drill the corrugated slate 18 and almost no scraping or noise is generated when the insertion hole is opened. There is an advantage that construction can be done without doing.
JP 2002-155600 A

  As described above, in the double-strung structure of Patent Document 1, when the saddle 19 is attached to the corrugated slate 18, the composite bolt 20 is screwed and fixed to the male thread portion 10a of the hook bolt 10 inserted through the through hole portion 12. There is a need to. However, the work of screwing the composite bolt 20 onto the male threaded portion 10a on a roof with high and unstable scaffolding is very complicated and dangerous, and is a factor that reduces the efficiency of renovation work. It was. Further, when the length of the hook bolt 10 protruding from the through-hole portion 12 of the saddle 19 is short, the amount of the hook bolt 10 and the composite bolt 20 to be screwed is insufficient, and the fixing force of the saddle 19 is reduced. There was also a drawback. In addition, when the male screw portion 10a is rusted or distorted due to deterioration over time, the composite bolt 20 may not be screwed. Especially on roofs that require refurbishment, the hook bolt 10 may rust and become candle-like, and the conventional composite bolt 20a may not be screwed at all. That is, in the conventional fixing structure of the saddle 19, there is a problem that the work of repairing the wave slate 18 cannot be performed depending on the protruding amount and state of the hook bolt 10.

  In view of the above-mentioned problems inherent in the prior art described above, the present invention has been proposed to suitably solve this problem, and can be easily and reliably fixed to a waveform slate, and an existing hook. An object of the present invention is to provide a saddle for corrugated slate repair that can be fixed even if the protruding amount of the bolt is short.

In order to overcome the above problems and achieve the intended purpose, the saddle for waveform slate repair according to the present invention is:
A saddle used to support the exterior material fixed to the outside of the corrugated slate when renovating to arrange a new exterior material outside the corrugated slate,
A flat portion that has an opening set to an inner diameter larger than the outer diameter of an existing hook bolt that protrudes outward from the chevron portion of the corrugated slate, and supports the exterior material;
A support portion that extends obliquely outward on both sides of the flat portion and abuts on both sides of the corrugated slate chevron when the hook bolt is inserted through the opening;
A pair of first engaging pieces that are concentric with the opening and extend inward of the opening, and the pair of first engaging pieces are spaced apart from each other in the circumferential direction and face the flat portion. A pair of second engagement pieces that are shorter than the respective first engagement pieces and extend inward of the opening, and the open ends of these four engagement pieces are elliptical in diameter smaller than the outer diameter of the hook bolt. Define the through hole,
When the hook bolt is inserted into the through hole, the open end of the first engagement piece engages with the hook bolt, and the open end of the second engagement piece is lower than the first engagement piece. It is characterized by being configured to be engaged with the hook bolt and fixed to the corrugated slate.

  According to the saddle for waveform slate repair according to the present invention, it can be fixed to the waveform slate simply by pushing in the saddle without using a fixing member such as a bolt as in the prior art. It becomes extremely easy. As a result, the work efficiency can be improved and the cost for repairing the waveform slate can be reduced. Further, since the protrusion amount of the hook bolt is sufficient to allow the first engagement piece and the second engagement piece to be engaged, even if the protrusion amount of the hook bolt is short, the fixing force of the saddle is reduced, The problem that it cannot be fixed can be avoided. Furthermore, even if the male thread portion of the hook bolt is rusted or slightly deformed, the saddle can be securely fixed. In particular, even for a hook bolt that rusts in a candle shape, the first and second engagement pieces are hard to rust on the surface and engage with the inside of the hook bolt, so that the saddle can be securely fixed.

  Next, a saddle for waveform slate repair according to the present invention will be described below with reference to the accompanying drawings with a preferred embodiment. The example shows the case where the saddle of the present invention is used when repairing the corrugated slate installed on the roof of a warehouse or factory, etc., but the corrugated slate as the outer wall material forming the outer wall of the warehouse or the like is repaired. In this case, the saddle of the present invention can be used. Moreover, in the following description, the same code | symbol shall be attached | subjected about the same member demonstrated by the prior art.

  In the saddle 40 for corrugated slate repair shown in the embodiment, for example, as shown in FIG. 1, a separate metal roof material (exterior material) 30 is newly provided on the existing roof using the corrugated slate 18. Used in the renovation method to install and make double structure. A hook bolt 10 is inserted into the corrugated slate 18 through a through-hole drilled in the top of the chevron 18a. The hook bolt 10 is bent at an acute angle with a lower end portion locked to a purlin (structure material) (not shown), and an upper portion provided with the male screw portion 10 a extends above the corrugated slate 18. Has been placed. The corrugated slate 18 is supported and fixed to the purlin girder by screwing the nut 34 into the male screw portion 10a.

  As shown in FIG. 1, a saddle 40 bent into a cross-sectional mountain shape having a flat portion 42 is disposed on a male screw portion 10 a of a hook bolt 10 that supports and fixes the corrugated slate 18. The flat portion 42 is set to have a width that can substantially cover the vicinity of the top portion of the mountain-shaped portion 18a, and an elliptical (oval-shaped) through-hole portion 44 through which the hook bolt 10 is inserted at a substantially central portion thereof. Is provided. A pair of skirt portions (support portions) 46 and 46 are provided on both sides of the flat portion 42 in the longitudinal direction so as to extend obliquely downward (outward) from each other. In the present invention, the elliptical shape that is the shape of the through-hole portion 44 is not limited to a strict ellipse, but is a concept including a shape such as an elliptical shape or a track shape having a parallel portion.

As shown in FIG. 2A, the through-hole portion 44 is separated from the open ends 48a, 48a of the pair of first engagement pieces 48, 48 in the circumferential direction. The pair of second engagement pieces 50, 50 that are shorter than the first engagement piece 48 are defined in an elliptical shape by the open ends 50a, 50a. In the embodiment, a thin plate-like metal plate separate from the saddle 40 is punched, and four elastically deformable parts including a pair of first engagement pieces 48 and 48 and a pair of second engagement pieces 50 and 50 are possible. An engagement piece is formed, and an elliptical through hole 44 is formed by the open ends 48a, 48a, 50a, 50a of the engagement pieces 48, 48, 50, 50. The plate-like piece 52 formed with these engagement pieces 48, 48, 50, 50 is opened in the flat part 42 of the saddle 40 and has an opening 54 set to an inner diameter larger than the outer diameter of the hook bolt 10. It is joined in a state corresponding to. That is, as shown in FIG. 2B, the first engagement pieces 48 extend in the minor axis direction of the elliptical through hole 44 and face each other across the center of the opening 54. And extends inward of the opening. The second engaging pieces 50, 50 are set to have a dimension l ₂ shorter than a dimension l ₁ of the first engaging piece 48. Both the second engagement pieces 50, 50 are provided to face each other with the center of the opening 54 interposed therebetween, and extend in the long axis direction of the through hole 44 toward the inside of the opening. The opening dimension (the inner diameter of the major axis and the inner diameter of the minor axis) of the through hole portion 44 defined by the first and second engaging pieces 48, 48, 50, 50 is larger than the outer diameter of the hook bolt 10. The first and second engaging pieces 48, 48, 50, 50 are elastically deformed to engage with the hook bolt 10 when the hook bolt 10 is inserted into the through hole 44. ing. The through hole 44 is defined to be concentric with the opening 54.

  That is, when the saddle 40 is pushed in and inserted into the through hole 44 of the hook bolt 10, as shown in FIGS. 3 (a) and 3 (b), the first and second engaging pieces 48, 48, 50, 50 Are elastically deformed by the hook bolt 10, and the respective open ends 48a, 48a, 50a, 50a are engaged with the male screw portion 10a. At this time, the engagement position of the first engagement piece 48 (see FIG. 3A) is higher than the engagement position of the second engagement piece 50 (see FIG. 3B). Is located. That is, by providing a difference in the length dimension of the first engagement piece 48 and the second engagement piece 50, the portion engaged with the hook bolt 10 is shifted up and down, and the two-stage engagement structure has a difference in height. Has been achieved. In the embodiment, the height difference between the engagement positions of the first and second engagement pieces 48 and 50 is set to be about 5 mm.

  The plate-like piece 52 described above may be any material as long as it is a metal material. However, considering weather resistance, workability, elasticity, etc., titanium or tough stainless steel is particularly suitable as the material. is there. Further, for the punching process for forming the first and second engagement pieces 48, 50, for example, a plurality of (18 in the embodiment) small holes are formed by a turret punch on a titanium standard plate, The plate-like piece 52 is formed by cutting into square pieces with a shear (shearing machine). Further, the through-hole portion 44 is formed, for example, by slightly shifting a circle formed by two punches. However, the method of forming the first and second engaging pieces 48 and 50 and the through hole 44 is not limited to the method using a turret punch, and may be formed by other methods.

  A skirt portion 46 extending obliquely downward from both edges of the flat portion 42 is configured to straddle so as to cover substantially the entire chevron 18a when the saddle 40 is seated on the corrugated slate 18. . And the edge parts 46a and 46a of both the skirt parts 46 and 46 contact | abut to the both sides which pinch | mount the mountain-shaped part 18a in the waveform slate 18, and are supporting the metal roof material 30 mentioned later. As shown in FIG. 1, on the saddle 40 attached to the corrugated slate 18, a channel material 56 having a required U-shaped cross section extends in a direction intersecting with the extending direction of the mountain-shaped portion 18 a of the corrugated slate 18. It is arranged to exist. In this state, the channel member 56 and the saddle 40 are fixed by screwing the tapping screw 58 into the flat portion 42 of the saddle 40 through the channel member 56. In addition, the newly laid metal roof material 30 is a folded plate formed by forming a plurality of trapezoidal peak portions 60, 60, and a valley portion 62 that contacts the channel material 56 between the peak portions 60. , 62 are formed. Then, the metal roof material 30 is arranged on the channel material 56 fixed to the saddle 40, and the tapping screw 64 is screwed into the channel material 56 via the valley portion 62 of the metal roof material 30, so that these metal roof material 30 and The channel material 56 is fixed. In addition, about the cross-sectional shape of the metal roof material 30, it is not necessarily limited to an Example, For example, conventionally well-known roof materials, such as a cross-sectional wave shape thing and a rectangular shape, are used. In addition, as shown in FIG. 1, the heat insulating effect in the building after the repair may be improved by interposing a heat insulating material 66 between the metal roof material 30 and the channel material 56. That is, the heat insulating material 66 is disposed on the channel material 56, the metal roof material 30 is further installed thereon, and these are fixed by the tapping screw 64.

(Operation of Example)
Next, the operation of the saddle 40 for modifying the waveform slate according to the embodiment will be described below together with the procedure for modifying the waveform slate. First, the hook bolt 10 faces the through hole 44 of the saddle 40 and the saddle 40 is pushed downward. Then, since the opening dimension of the through-hole portion 44 is set smaller than the outer diameter of the hook bolt 10, the first and second engagement pieces 48 and 50 are elastically deformed upward by the hook bolt 10. . Then, the saddle 40 is pushed in until the skirt portion 46 comes into contact with the middle of the corrugated slate 18, and the saddle 40 is straddled across the chevron 18a. At this time, as shown in FIGS. 3 (a) and 3 (b), the first engagement pieces 48, 48 are engaged on the upper side of the hook bolt 10, and the second engagement pieces 50, 50 are engaged with the hook bolt 10. The saddle 40 is fixed in a stepped engagement structure that is engaged at the lower side and has a height difference with respect to the hook bolt 10. Therefore, the saddle 40 is securely engaged with the hook bolt 10 and firmly attached to the corrugated slate 18.

  Next, the channel material 56 is positioned on the saddle 40 so as to extend in a direction intersecting with the extending direction of the mountain-shaped portion 18 a in the corrugated slate 18. In this state, the tapping screw 58 is screwed into the saddle 40 via the channel material 56, and the channel material 56 is fixed on the saddle 40. Further, the metal roof material 30 is placed on the channel material 56 fixed to the saddle 40, and the valley portion 62 of the metal roof material 30 is brought into contact with the channel material 56. In this state, the metal roofing material 30 is fixed onto the channel material 56 by screwing the tapping screw 64 into the channel material 56 via the valley portion 62. Further, when the heat insulating material 66 is laid between the metal roof material 30 and the channel material 56, the heat insulating material 66 is disposed on the channel material 56 before the metal roof material 30 is fixed, and from above. The metal roof materials 30 are arranged and fixed with tapping screws 64. Thereby, it becomes possible to improve the heat insulation effect in the building after repair.

  That is, according to the saddle 40 for wave slate repair according to the embodiment, it is possible to fix the corrugated slate 18 to the corrugated slate 18 by simply pushing it in, without using a fixing member such as a bolt as in the prior art. Therefore, the mounting work on the waveform slate 18 becomes extremely efficient, the time required for the repair is shortened, and the repair cost of the waveform slate 18 can be reduced. Even if the protrusion amount of the hook bolt 10 is short, the first engagement pieces 48 and 48 and the second engagement pieces 50 and 50 are reliably engaged, so that the fixing force of the saddle 40 is reduced or the saddle 40 is reduced. Can be avoided. Furthermore, since the saddle 40 of the embodiment can be fixed simply by being pushed in, even if the hook bolt 10 is rusted or slightly deformed, the saddle 40 can be easily attached to the corrugated slate 18.

  In the saddle 40 of the embodiment, the first and second engagement pieces 48 and 50 and the through hole portion 44 are formed in the plate-like piece 52 and welded to the flat portion 42. The first and second engagement pieces 48 and 50 and the through hole 44 may be formed directly on the flat portion 42 of the saddle 40. Moreover, the repair method using the channel material 56, the metal roof material 30, etc. which were shown in the Example shows one example, and can be repaired by other methods. For example, in the embodiment, the metal roof material 30 is installed on the saddle 40 via the channel material 56, but the metal roof material 30 may be directly fixed to the saddle 40.

(Change example)
In the saddle 40 according to the above-described embodiment, the plate-like piece 52 is bonded to the surface side of the flat portion 42, but the plate-like piece 52 may be bonded to the back side of the flat portion 42. That is, as shown in FIG. 4, in the saddle 41 according to the modified example, when the plate-like piece 53 is joined to the back surface of the flat portion 42 and the hook bolt 10 is inserted into the opening 54, the plate-like piece 53 is It is configured to contact the nut 34. Further, when the hook bolt 10 is made to the opening 54, the first engagement pieces 49, 49 and the second engagement pieces 51, 51 face outward through the opening 54, The open ends 49 a, 49 a, 51 a, 51 a of the first and second engagement pieces 49, 49, 51, 51 are engaged with the hook bolt 10.

  That is, the saddle 41 according to the modified example is provided with the plate-like piece 53 on the back side of the flat portion 42, so that the first and first plates are compared with the case where the plate-like piece 52 is joined to the surface of the flat portion 42 as in the embodiment. The amount of protrusion of the hook bolt 10 from the nut 34 necessary for the engagement of the two engaging pieces 49 and 51 can be shortened by the thickness of the flat portion 42. In other words, even with the hook bolt 10 slightly protruding from the nut 34, the saddle 41 according to the modified example can be fixed. Incidentally, as shown in FIG. 4, the shortest distance from the nut 34 to the front end portion 49a of the first engagement piece 49 is about 4 mm, and the shortest distance from the nut 34 to the front end portion 51a of the second engagement piece 51 is about It is set to 2 mm. Therefore, in this case, if the protruding amount of the hook bolt 10 from the nut 34 is about 5 mm, the saddle 41 according to the modified example can be engaged and fixed. However, the shortest distance between the tip end portions 49a and 51a and the nut 34 when the first and second engaging pieces 49 and 51 are engaged is not limited to the above value, and may be changed as appropriate according to the embodiment. That's fine. In addition, about the other structure in the saddle 41 concerning a modification, since it is the same as that of the saddle 40 shown in the Example, description is abbreviate | omitted.

  Here, the hook bolt 10 rusts due to deterioration over time, and a candle-like rust 70 may be formed on the surface of the hook bolt 10 as shown by the broken line in FIG. However, even in such a hook bolt 10, the candle-like rust 70 is formed only on the surface of the hook bolt 10, and the inside thereof still has rigidity in many cases. Accordingly, in the saddle 41 according to the modified example, the first and second engaging pieces 49 and 51 are hard to be rusted on the surface 70 and firmly engaged with the inside of the hook bolt 10 having rigidity, thereby the saddle. 41 secure fixation is achieved. The same can be said for the saddle 40 according to the embodiment described above. Note that the plate-like piece 53 provided in the saddle 41 according to the modified example has an elliptical through hole 45 with a major axis set to 5.91 mm and a minor axis 4.5 mm, for example, as shown in FIG. The turret punch defines first and second engaging pieces 49, 49, 50, 50 and a through hole 45 by a total of 23 small holes. That is, in the saddle 41 according to the modified example, the ratio (ellipticity) of the minor axis to the major axis of the through hole 45 is set to about 0.76. However, the value of the ellipticity can be appropriately changed within a range of 0.6 to 0.85, for example.
