Description

  The present invention relates to an eaves-inspection walkway, and more particularly, to a technique for installing a walkway as an inspection space in an eaves-end portion of a corrugated slate roof.

Corrugated slate plates have been widely used as roofing materials for large buildings such as factories, warehouses, and gymnasiums, and various techniques for repairing the entire roof without removing old slate plates have been put into practical use. Yes.
For example, in Patent Document 1 below, a clamp fitting is driven in between a washer of a hook bolt protruding on the surface of a slate roof and a slate plate, and then a plurality of metal plate roof materials are covered on the slate roof. A roof repair method is disclosed in which these are screwed to a clamp fitting.

  In the case of this roof repair method, it is basically necessary to cover the entire slate roof with a new metal plate roofing material, so there is no need to interrupt the use of the building, and the metal plate roofing material is an existing one that protrudes from the roof surface. Since it is engaged with the hook bolt via the clamp fitting, there is an advantage that it is not necessary to perform drilling or the like on the slate roof.

By the way, since the slate roof itself has not deteriorated, it is not necessary to carry out a full repair as described above, but there is a desire to form a work space by laying a metal plate roof material on a part thereof. Yes.
For example, in order to check an outdoor unit of an air conditioner installed on the roof of a building, a metal plate roofing material is installed on the eaves portion of the corrugated slate roof and used as a walkway.

In this way, there is no doubt that higher safety is ensured compared to the situation where workers are standing on a fragile corrugated slate roof or on a slippery rain gutter for inspection.
However, if a metal plate roofing material is laid on a part of an existing slate roof, rainwater intrudes from between the metal plate roofing material and the slate plate, rusting the clamp fittings, or hooks generated by driving the clamp fittings. There is a concern that water leaks indoors through the gap between the bolt and the slate plate.

  For this reason, in the following Patent Document 2, as shown in FIG. 12, the clamp fitting 38 is covered with a plurality of vertical base materials 14 arranged in a direction parallel to the wave rows of the slate plate 34, and at the rear end thereof. The curved portion 32 formed by pressing (see FIG. 13) is inserted into the gap 51 at the overlapping portion between the slate plate 34a on the eaves side and the other slate plate 34b arranged on the upper side. (See FIG. 14), a technique for fixing the walkway material 16 on each vertical base material 14 is disclosed.

  In the case of this prior art, the clamp fitting 38 engaged with the hook bolt 36 is covered with the vertical base material 14, and the curved portion 32 of the vertical base material 14 is inserted into the gap 51 between the slate plates 34a and 34b. Therefore, even if it rains, it is blocked by the vertical base material 14, and the clamp fitting 38 is not directly exposed to rainwater. For this reason, it is possible to effectively avoid rusting of the clamp fitting 38 or leakage of water indoors through the hook bolt 36.

Japanese Patent Laid-Open No. 10-219936 JP 2006-125206 A

  However, in the technique of Patent Document 2, the curved base 32 formed at the rear end of the relatively long vertical base material 14 is pressed into the gap 51 between the slate plates 34a and 34b. Since the main body side is fixed to the slate plate 34a with the tex screw 52, a large repulsive force (force to jump up) is generated in the curved portion 32 of the vertical base material 14 by the principle of the lever.

As a result, cracks 90 and breakage 92 are likely to occur at the end of the slate plate 34b (FIG. 14), and this may lead to water leakage as well as loss of aesthetics.
Further, the vertical base material 14 needs to have a certain thickness (for example, 1.2 mm) in order to secure the function of supporting the walkway material 16, but this thickness becomes a wrinkle, and the gap 51 between the slate plates 34a and 34b. It was also pointed out that it was difficult to insert into the.

  The present invention has been devised to solve such problems, and covers a part of the slate roof with a metal plate roof material without causing rusting of clamp fittings by rainwater or leakage of water into the room. An object of the present invention is to provide a technique capable of forming a work space, avoiding cracks and breakage of a slate plate, and improving workability.

  In order to achieve the above object, the eaves inspection walkway according to claim 1 is for eaves inspection having a structure in which a corridor made of a metal plate roof is attached to the surface of a slate roof in which a plurality of corrugated slate plates are arranged. A plurality of clamp fittings engaged with existing hook bolts protruding outward from the top of the slate plate, and a plurality of vertical bases arranged in a direction parallel to the wave rows of the slate plate. Material, and a plurality of insertion members connected to the rear end of each vertical base material, the vertical base material is an upper plate, both side plates, and a storage space surrounded by these upper plates and both side plates, The insertion member includes a lower surface opening, and the insertion member includes an upper plate, both side plates, a storage space surrounded by the upper plate and the both side plates, a lower surface opening, and a curved portion formed on the rear end side. Cover the bottom opening of the vertical base material to the clamp bracket. Thus, the clamp metal fitting is disposed in the storage space, and the upper surface of the clamp metal fitting and the upper base plate of the vertical base material are screwed together, and the curved portion of the insertion member is connected to the eaves edge. The slate plate on the side and the other slate plate disposed on the upper side of the slate plate are inserted into the gap between the overlapping portions. The rear end of the vertical base material is disposed in the storage space, and the space between the upper base plate of the vertical base material and the upper plate of the insertion member is screwed, and the walkway material is disposed on the vertical base material. It is characterized by being screwed between the two.

  Further, the eaves inspection walkway according to claim 2 is the eaves inspection walkway according to claim 1, wherein the walkway material is made of a corrugated steel plate, and the row of waves intersects the longitudinal direction of the vertical base material. It is characterized by being arranged on the vertical base material in the orientation.

  The eaves inspection walkway according to claim 3 is an eaves inspection walkway having a structure in which a corridor material made of corrugated steel plates is attached to a surface of a slate roof in which a plurality of corrugated slate plates are arranged. A plurality of clamp fittings engaged with existing hook bolts protruding outward from the top, a plurality of vertical base materials arranged in a direction parallel to the wave rows of the slate plate, and after each vertical base material A plurality of insertion members connected to the ends, and a plurality of horizontal base materials arranged in a direction intersecting with each vertical base material and fixed thereto, the vertical base material comprising an upper plate and both sides A plate, a storage space surrounded by the upper plate and both side plates, and a lower surface opening, and the insertion member includes an upper plate, both side plates, and a storage space surrounded by the upper plate and both side plates, A lower surface opening and a curved portion formed on the rear end side, By covering the lower opening of the vertical base material on the clamp fitting, the clamp fitting is disposed in the storage space, and the upper surface of the clamp fitting and the upper plate of the vertical base piece are screwed together. The curved portion of the insertion member is inserted into a gap between overlapping portions of the slate plate on the eaves side and another slate plate disposed on the upper side of the eaves side. By covering the upper base plate of the vertical base material, the rear end of the vertical base material is arranged in the storage space, and the upper base plate of the vertical base material and the upper plate of the insertion member are screwed. The corridor material is characterized in that the row of waves is arranged on the horizontal base material in a direction parallel to the longitudinal direction of the vertical base material, and is screwed between the two.

  The eaves inspection walkway according to claim 4 is the eaves inspection walkway according to claims 1 to 3, and a drainage ridge portion is formed on each side edge of the vertical base material. It is characterized by.

  In the eaves inspection walkway according to the present invention, the vertical base material that supports the walkway material covers the clamp fitting engaged with the hook bolt, and the rear end of the vertical base material is covered by the insertion member. In addition, since the curved part of the insertion member is press-fitted into the gap with the slate plate located in the upper stage, even if it rains, it is blocked by the insertion member and the vertical base material, and the clamp fitting is directly exposed to rainwater There is no. For this reason, it can avoid effectively that a clamp metal fitting rusts with rain water, or leaks indoors along a hook bolt.

  Moreover, since the insertion member inserted into the gap of the slate plate and the vertical base material that supports the walkway material are separated as separate members, the repulsive force applied to the lower end of the slate plate located in the upper stage is also dispersed and Reduced.

Further, the vertical base material needs to have a certain thickness in order to support the walkway material, but the insertion member does not need to withstand a large load, and thus can be made thinner.
As a result, it becomes easy to insert into the gap between the slate plates, and the workability can be improved.

FIG. 1 is a perspective view showing the overall configuration of a first eaves-inspection walkway 10 according to the present invention, in which a plurality of vertical base materials 15 installed on an eaves portion of a slate roof 12 and each vertical base material 15 are shown. A plurality of insertion members 60 connected to the rear end side and a plurality of walkway materials 16 attached on the respective vertical base materials 15 are provided.
The walkway material 16 is made of a corrugated steel plate.

  The slate roof 12 is formed by arranging a plurality of slate plates on the roof roof and fixing them via hook bolts 36. The slate roof 12 is formed on the upper end side of the slate plate 34a arranged on the eaves side of the roof. Each slate plate is positioned so that the lower end sides of the slate plate 34b arranged in the upper stage overlap with a certain width.

  The vertical base material 15 is made of a metal material that is not easily rusted, such as stainless steel. As shown in FIG. 2, the vertical base material 15 has a relatively long length including an upper plate 20, a first side plate 22, and a second side plate 24. It consists of a rod-shaped member.

  A first flange portion 26 is formed on the end side of the first side plate 22 so as to be folded back upward. In addition, a second flange portion 28 that is folded back upward is also formed on the end side of the second side plate 24.

A storage space 30 surrounded by the upper plate 20, the first side plate 22, and the second side plate 24 is formed inside the vertical base material 15.
A lower surface opening 31 is formed between the first side plate 22 and the second side plate 24.

  The insertion member 60 is made of a rust-resistant metal material such as stainless steel, and as shown in FIG. 3 (a), a connecting portion 61 having a shape similar to that of the vertical base material 15 and a curved portion 62 having a cross-sectional wave shape. It has.

FIG. 3B shows a material 63 for forming the insertion member 60.
The material 63 has a shape and dimensions similar to those of the vertical base material 15 except that the length dimension is relatively short.

First, the material 63 includes an upper plate 64, a first side plate 65, and a second side plate 66.
In addition, a first flange portion 67 that is folded back upward is formed on the end side of the first side plate 65.
A second collar portion 68 that is folded back upward is also formed on the end side of the second side plate 66.

A storage space 69 surrounded by the upper plate 64, the first side plate 65 and the second side plate 66 is formed inside the material 63.
A lower surface opening 70 is formed between the first side plate 65 and the second side plate 66.

Then, by applying a pressing process (drawing process) to the rear end portion of the material 63, a bending portion 62 for insertion is formed, and the insertion member 60 is completed.
The curved portion 62 has a shape corresponding to one wave of the slate plate 34.
Further, a portion of the material 63 other than the curved portion 62 serves as the connecting portion 61.

  FIG. 4 shows an installation method of the vertical base material 15. First, a clamp is applied to the hook bolt 36 protruding from the top of the corrugated slate plate 34 a arranged on the eaves side of the slate roof 12. The metal fitting 38 is engaged (FIG. 4 (a)).

The clamp fitting 38 is a box having a trapezoidal cross section that is open at the front end side and the rear end side. As shown in FIG. 5, the bottom face 40 has a guide notch 46 that extends from the front end opening 42 to the rear end opening 44. Is formed.
The notch 46 includes an inverted triangular portion 46a on the front end opening 42 side, a circular portion 46b in the middle, and a rectangular portion 46c on the rear end opening 44 side.

By inserting the inverted triangular portion 46a of the notch 46 of the clamp fitting 38 into the back side of the nut 48 and the washer 50 screwed to the tip of the hook bolt 36 and driving it from the side with a hammer, the clamp fitting 38 is hook hook bolt 36 is engaged.
At this time, the hook bolt 36 is accommodated in the circular portion 46b of the notch 46.

Next, the lower surface opening 31 of the vertical base material 15 is placed on the clamp fitting 38 and introduced into the storage space 30 (FIG. 4B).
Then, the space between the upper plate 20 of the vertical base material 15 and the upper surface 54 of the clamp fitting 38 is fixed by the text screw 52.
As shown in FIG. 6, a washer 50 is arranged between a nut 48 screwed to the tip of the hook bolt 36 and the top of the slate plate 34, and a packing 56 and a slate fixed to the back surface of the washer 50. The bottom surface 40 of the clamp fitting 38 is sandwiched by the top of the plate 34.

FIG. 1 shows an example in which one vertical base material 15 is fixed to a slate plate 34a at two locations by using two clamp fittings 38.
However, the number of fixed portions between the vertical base material 15 and the slate plate 34a is not particularly limited.

  Next, as shown in FIG. 7, after inserting the curved portion 62 of the insertion member 60 into the gap 51 at the overlapping portion between the slate plate 34a on the eaves side and the other slate plate 34b arranged on the upper side thereof Then, the connecting portion 61 is placed on the vertical base material 15, and the overlapping portion of both is fixed via a plurality of text screws 52.

Next, a plurality of walkway materials 16 are placed on the upper plate 20 of the plurality of vertical base materials 15.
At this time, the row of waves formed on each corridor 16 is arranged in a direction (lateral direction) orthogonal to the row of waves formed on the slate plate 34.

Then, as shown in FIG. 6, the tex screw 52 is inserted into the screw hole of the wave washer 58 disposed on the top of the walkway material 16 and is screwed to the upper plate 20 of the vertical base material 15.
As a result, the walkway material 16 is firmly fixed to the vertical base material 15.

  In the case of the first eaves inspection gallery 10, the clamp fitting 38 engaged with the hook bolt 36 is covered with the vertical base material 15, and the insertion member 60 connected to the rear end of the vertical base material 15 is provided. Since the curved portion 62 is press-fitted into the gap 51 between the slate plate 34a on the eaves side and the slate plate 34b positioned one level higher than the slate plate 34a, rainwater can be removed by the vertical base material 15 and the insertion member 60 even if it rains. And the clamp fitting 38 is not directly exposed to rainwater.

For this reason, it is possible to effectively prevent the clamp fitting 38 from being rusted by rainwater or leaking indoors through the hook bolt 36.
The rainwater that has fallen on the vertical base material 15 and the insertion member 60 is transported to the lower side of the slate roof 12 through the first ridge part 26 and the second ridge part 28 of the vertical base material 15 and collected in the rain gutter 62. It is done.

  In the case of the first eaves-inspection walkway 10, since the wave trains of the walkway materials 16 are arranged in the horizontal direction and these act as a scaffold, there is also an advantage that the operator can easily climb the hill.

As shown in FIGS. 12 and 13, in the prior art, the rear end side itself of the vertical base material 14 is processed into a corrugated shape, and the curved portion 32 is inserted into the gap 51. Is added to the slate plate 34b.
On the other hand, the first eaves inspection walkway 10 is divided into a relatively long vertical base material 15 that supports the walkway material 16 and a relatively short insertion member 60 that is inserted into the gap 51. Accordingly, the repulsive force of the bending portion 62 applied to the slate plate 34b is also dispersed / reduced.
For this reason, it is possible to prevent the slate plate 34b from being cracked or damaged.

Further, by using the insertion member 60 and the vertical base material 15 as separate members as described above, the insertion member 60 can be made of a thinner material.
For example, the thickness of the vertical base material 15 is 1.2 mm, which is sufficient to support the walkway material 16, while the insertion member 60 is formed of the material 63 having a thickness of 0.5 mm.
As a result, there is an advantage that the curved portion 62 can be easily inserted into the narrow gap 51.

  FIG. 8 is a perspective view showing the entire configuration of the second eaves inspection corridor 71 according to the present invention, in which a plurality of vertical base materials 15 installed on the eaves portion of the slate roof 12 and the vertical base materials 15 are shown. A plurality of insertion members 60 connected to the rear end side, a plurality of horizontal base materials 72 mounted on each vertical base material 15, and a plurality of walkway materials fixed on each horizontal base material 72 Has 16.

The corridor 16 is made of corrugated steel plate similar to the above, but the wave train formed on each corridor 16 is arranged in a direction (longitudinal direction) parallel to the wave train formed on the slate plate 34. The
Further, in the case of the first eaves inspection walkway 10, the walkway material 16 is directly fixed to the upper plate 20 of the vertical base material 15, whereas in the case of this second eaves inspection walkway 71, It is characterized in that each gallery material 16 is fixed on a horizontal base material 72 fixed on the vertical base material 15.

  In addition, since the structure and installation method of the vertical base material 15 and the insertion member 60 are the same as the case of the first eaves-inspection walkway 10, the following will focus on the characteristic parts of the second eaves-inspection walkway 71. explain.

First, the horizontal base material 72 is made of a metal material that does not easily rust, such as stainless steel. As shown in FIG. 9, the horizontal base material 72 is a relatively long material including an upper plate 74, a first side plate 76, and a second side plate 78. It consists of a rod-shaped member.
A first edge 80 bent in the horizontal direction is formed on the end side of the first side plate 76. Further, a second edge 82 bent in the horizontal direction is formed on the end side of the second side plate 78 on the outer side.

  As shown in FIG. 9, the horizontal base material 72 is placed on the upper plate 20 of the vertical base material 15 in a direction orthogonal thereto, and the first edge 80 and the second edge are interposed via the text screw 52. The part 82 is screwed to the upper plate 20 of the vertical base material 15.

Next, as shown in FIG. 8, a plurality of walkway materials 16 are placed on a pair of horizontal base materials 72.
At this time, the wave trains of the respective walkway materials 16 are arranged in a direction orthogonal to the longitudinal direction of the lateral base material 72.

Next, as shown in FIG. 10, the tex screw 52 is inserted into the screw hole of the wave washer 58 arranged at the top of the corridor 16 and is screwed to the upper plate 74 of the lateral base material 72.
As a result, the walkway material 16 is firmly fixed to the lateral base material 72.

  FIG. 8 shows an example in which each walkway material 16 is supported by two horizontal base materials 72 arranged in parallel at a predetermined interval, but three or more horizontal base materials 72 are installed. However, it may be configured such that each gallery member 16 is fixed thereon.

In the case of the second eaves inspection gallery 71 as well, the clamp fitting 38 engaged with the hook bolt 36 is covered by the vertical base material 15, and the insertion member 60 connected to the rear end of the vertical base material 15. The curved portion 62 is press-fitted into the gap 51 between the slate plate 34a on the eaves side and the slate plate 34b positioned one level higher than the slate plate 34a, so that even if it rains, the vertical base material 15 and the insertion member 60 The clamp metal fitting 38 is not directly exposed to rainwater.
For this reason, it is possible to effectively prevent the clamp fitting 38 from being rusted by rainwater or leaking indoors through the hook bolt 36.

Further, since the function of the conventional vertical base material 14 is divided into the vertical base material 15 that supports the walkway material 16 and the horizontal base material 72 and the insertion member 60 that is inserted into the gap 51, in addition to the slate plate 34b, The repulsive force of the curved portion 62 is also dispersed and reduced. As a result, it is possible to prevent the slate plate 34b from being cracked or damaged.
Thus, by using the insertion member 60 and the vertical base material 15 as separate members, the insertion member 60 can be made of a thinner material.

  In addition, the second eaves inspection gallery 71 has an advantage that it can be used as a part of a new roof as it becomes necessary to repair the entire slate roof 12 with corrugated steel in the future. .

Furthermore, since the lateral base material 72 is arranged on the back surface of the walkway material 16, and the walkway material 16 is screwed to the horizontal base material 72, the walkway material 16 can be fixed at an arbitrary pitch. Is possible.
That is, if the walkway material 16 is directly fixed to the vertical base material 15 without providing the horizontal base material 72, the fixing location is limited to the position where the vertical base material 15 exists.

In the above description, the corrugated steel plate is used as the corridor material 16, but a flat metal plate may be used as the corridor material 16.
Further, in the above, an example in which the upper plate 20 of the vertical base material 15 is formed in a flat plate shape is shown. However, as shown in FIG. 11, as shown in FIG. A base material 15 can also be used. In this case, although not shown, it is desirable to adopt the insertion member 60 having a plurality of concave grooves formed on the upper plate 64.
