Description

The present invention relates to reinforcing metal fittings that reinforce the ridge envelope placed on the ridge of a building roof, and to a ridge structure and ridge construction method that use the same.

Ridge wrap is made by bending steel plates and is placed on the ridge of a building roof. Placing the ridge wrap on the ridge of a building roof prevents rain and other elements from entering through the ridge.

Generally, the ridge plaster is a long component with a mountain-shaped section at the top of the ridge, and is installed together with the crosspiece. The crosspiece is placed along the length of the ridge of the roof and is used to secure the ridge plaster. The ridge plaster is placed over the crosspiece that is placed along the ridge, and then secured in place with fasteners such as nails. However, the durability of the ridge plaster weakens when the nails rust or the crosspiece corrodes, which can result in the ridge plaster being blown away by the wind or other factors.

Therefore, it is thought that durability can be improved by making the ridge envelope have a strong structure. For example, it is thought that durability can be improved by attaching the safety fittings described in Patent Document 1.

JP 2005-336990 A

However, because the safety fittings in Patent Document 1 are for attaching a lifeline, they have a complex structure and are difficult to install. In addition, because the safety fittings in Patent Document 1 are for attaching a lifeline, there is no mention at all of improving the durability of the ridge envelope. Furthermore, the safety fittings in Patent Document 1 are arranged so that two crosspieces located on both the left and right sides of the ridge are covered by one safety fitting, but arranging them in this way requires small adjustments to the crosspiece arrangement, which is time-consuming.

Therefore, the present invention was made in consideration of the above problems, and one of the objects of the present invention is to provide a reinforcing metal fitting that can easily reinforce the ridge envelope. It is also an object of the present invention to provide a ridge structure and a ridge construction method that use the reinforcing metal fitting.

To achieve the above objective, the present invention has at least the following configuration or executes the following steps.

A reinforcing metal fitting according to one aspect of the present invention is a reinforcing metal fitting arranged between a cross plate and a ridge envelope arranged toward the longitudinal direction of the ridge of a roof, for reinforcing the ridge envelope, the reinforcing metal fitting comprising an upper plate arranged on the upper surface of the cross plate and a side plate arranged along the eaves side side of the cross plate, the angle formed by the upper plate and the side plate being 85° to 105°.
With this configuration, the ridge wrap can be easily reinforced. When fixing the ridge wrap, a fastener such as a nail is used to fasten the ridge wrap to the cross plate from the side of the eaves side of the cross plate, but by providing the reinforcing metal fitting according to the present invention between the ridge wrap and the cross plate, the fastening can be made more firmly, resulting in a stronger structure for the ridge wrap.

A reinforcing metal fitting according to one aspect of the present invention is a reinforcing metal fitting arranged between a cross plate and a ridge envelope arranged toward the longitudinal direction of the ridge of a roof, for reinforcing the ridge envelope, the reinforcing metal fitting comprising an upper plate arranged on the upper surface of the cross plate and a side plate arranged along the eaves side side of the cross plate, the angle formed by the upper plate and the side plate being 85° to 105°, the upper plate being provided with a short side plate which is shorter than the side plate and positioned opposite the side plate, the angle formed by the upper plate and the short side plate being 85° to 105°, and the side plate being provided with a base plate extending toward the eaves side.
With this configuration, the ridge wrap can be easily reinforced. When fixing the ridge wrap, a fastener such as a nail is used to fasten the ridge wrap to the cross plate from the side of the eaves side of the cross plate, but by providing the reinforcing metal fitting according to the present invention between the ridge wrap and the cross plate, the fastening can be made more firmly, resulting in a stronger structure for the ridge wrap.

More preferably, the upper plate has a first through hole for passing a first fastener for fastening the through plate and the reinforcing metal fitting.
With this configuration, the through plate and the reinforcing metal fitting can be more easily fastened together.

More preferably, a reinforcing plate having a second through hole larger than the first through hole is provided on the back side of the upper plate so as not to block the first through hole.
With this configuration, the strength of the reinforcing metal fitting can be further improved by the reinforcing plate. In addition, when a metal plate is folded to create the reinforcing metal fitting, the first through hole is not blocked even if the metal plate is folded slightly out of alignment. In addition, when the reinforcing metal fitting is fixed onto the through plate using the first fastener, if the reinforcing metal fitting is folded into two layers, the surface of the reinforcing metal fitting can be kept flat.

A ridge structure according to one aspect of the present invention is a ridge structure which uses reinforcing metal fittings arranged between a cross plate and a ridge envelope arranged toward the longitudinal direction of the ridge of the roof, to reinforce the ridge envelope, the reinforcing metal fittings comprising an upper plate which is arranged on the upper surface of the cross plate at the ridge of the roof, and a side plate which is arranged along the eaves side side of the cross plate, the angle formed by the upper plate and the side plate being 85° to 105°, the ridge structure comprising a ridge beam arranged in the longitudinal direction of the ridge, a roofing material, the cross plate arranged on the roofing material, the reinforcing metal fittings arranged on the cross plate, and the ridge envelope arranged on the reinforcing metal fittings, a first fastener is driven from the upper plate of the reinforcing metal fittings toward the cross plate to fasten the cross plate and the reinforcing metal fittings, and a second fastener is driven toward the eaves side side of the cross plate to fasten the ridge envelope, the reinforcing metal fittings, and the cross plate.
With this configuration, the ridge wrap can be more easily made into a stronger structure.

A ridge construction method according to one aspect of the present invention is a ridge construction method that uses reinforcing metal fittings that are placed between a cross plate and a ridge envelope arranged toward the longitudinal direction of the ridge of the roof, to reinforce the ridge envelope, wherein the reinforcing metal fittings comprise an upper plate that is placed on the upper surface of the cross plate at the ridge of the roof, and a side plate that is arranged along the eaves side side of the cross plate, and the angle formed by the upper plate and the side plate is 85° to 105°, and is characterized in that the method includes the steps of: placing the cross plate toward the longitudinal direction of the ridge of the roof; placing the reinforcing metal fittings from above the cross plate; placing the ridge envelope from above the cross plate on which the reinforcing metal fittings are arranged; driving a first fastener from the upper plate of the reinforcing metal fittings toward the cross plate to fasten the cross plate and the reinforcing metal fittings; and driving a second fastener into the eaves side side of the cross plate to fasten the ridge envelope, the reinforcing metal fittings, and the cross plate.
This configuration allows for a strong structure that can be deployed using simple construction techniques.

As described above, the present invention makes it possible to easily make the ridge wrapping at the ridge section stronger.

Each embodiment of the present invention will be specifically described below with reference to the drawings. Note that the embodiment described below is merely a specific example for implementing the present invention, and is not intended to limit the interpretation of the present invention. Note that in the following description, symbols and the like shown in the drawings may be added to facilitate understanding of the present invention, but the components of the present invention are not limited to those shown in the drawings, and should be interpreted broadly to the extent that a person skilled in the art can technically understand them.

Figure 1 shows a ridge structure using a reinforcing metal fitting 100 according to the present invention. The ridge structure comprises a ridge beam 10 arranged in the longitudinal direction of the ridge, a roofing material 20, a crosspiece 30 arranged on the roofing material 20, a reinforcing metal fitting 100 arranged on the crosspiece 30, and a ridge wrapper 40 arranged on the reinforcing metal fitting 100. In addition, the tip of the first fastener 50 is driven into the ridge beam 10, and the tip of the second fastener 60 is driven into the crosspiece 30.

The roofing material 20 is placed on top of the sheathing boards 70. The roofing material 20 is made of slate, but is not limited to this, and various roofing materials 20 such as galvalume steel sheet (registered trademark), zinc-calium steel sheet, asphalt shingle, and galvanized iron can be used as appropriate.

The crosspieces 30 are arranged in the longitudinal direction of the ridge of the roof, and are arranged separately on the left and right sides of the ridge peak. When the crosspieces 30 are arranged, the side closer to the eaves side is the eaves side 31, and the side closer to the ridge peak is the ridge peak side 32. The ridge peak refers to the peak of the mountain shape of the ridge envelope that has been arranged.

The crosspiece 30 is made of wood, but is not limited to this and may be made of resin.

A long screw is used as the first fastener 50, but this is not limited to this and long nails or the like may also be used. The first fastener 50 is hammered into place from above the reinforcing metal fitting 100.

Although a drill screw is used as the second fastener 60, it is not limited to this and nails, screws, etc. can also be used. The second fastener 60 fastens the ridge wrap 40, the reinforcing metal fittings 100, and the crosspiece 30. The second fastener 60 is driven from above the ridge wrap 40 toward the side surface 31 on the eaves side of the crosspiece 30.

The ridge wrapper 40 is long and has a mountain-shaped area at the top of the ridge. The ridge wrapper 40 has been treated with various coatings. The ridge wrappers 40 are arranged in succession along the length of the ridge, straddling the ridge beam 10, and are arranged to wrap around the two crosspieces 30 that are located on either side of the top of the ridge.

Next, the reinforcing metal fitting 100 according to the present invention will be described. FIG. 2 is a perspective view showing the reinforcing metal fitting 100 according to the present invention, and FIG. 3 is a view showing the plan, front, and side of the reinforcing metal fitting 100 according to the present invention. FIG. 2(a) is a perspective view showing the front side of the reinforcing metal fitting 100, and FIG. 2(b) is a perspective view showing the back side of the reinforcing metal fitting 100. The reinforcing metal fitting 100 includes an upper plate 110 arranged on the upper surface of the cross plate 30, and a side plate 120 arranged along the side surface 31 on the eaves side of the cross plate 30, and the upper plate 110 and the side plate 120 are formed at an angle of approximately 90° as θ1. Note that θ1 is preferably in the range of 85° to 105°. In addition, the upper plate 110 is provided with a short side plate 130 formed shorter than the side plate 120 at a position opposite the side plate 120, and the upper plate 110 and the short side plate 130 are provided at an angle of approximately 90° as θ2. It is preferable that θ2 is in the range of 85° to 105°. In addition, the other end 140 of the side panel 120, which faces the end where the upper panel 110 and the side panel 120 are connected, is provided with a bottom panel 150 in a direction extending toward the eaves.

The reinforcing metal fitting 100 is formed by bending, and the metal plate is doubled. The back surface formed by bending is the reinforcing plate 160. The surface of the upper plate 110 of the reinforcing metal fitting 100 has a first through hole 111 for passing the first fastener 50 for fastening the through plate 30 and the reinforcing metal fitting 100. In addition, the reinforcing plate 160, which is the back surface of the upper plate 110, has a second through hole 161 larger than the first through hole 111. This is because the second through hole 161 is made larger than the first through hole 111 in consideration of misalignment due to bending. With this structure, when the reinforcing metal fitting 100 is formed by bending, the first fastener 50 can be more reliably formed to pass through the first through hole 111 and the second through hole 161. The reinforcing plate 160, which is the back surface, may be formed by attaching another metal plate.

It is preferable that the reinforcing bracket 100 has the first through hole 111 and the second through hole 161, but it is possible to drive in a fastening device such as a nail even if they are not provided. However, if the first through hole 111 and the second through hole 161 are not provided, it will be time-consuming to drive in a fastening device such as a nail.

In addition, when actually installing, it is preferable to apply waterproof tape or the like to the reinforcing plate 160 on the back surface of the reinforcing bracket 100 before installation. Specifically, waterproof tape with adhesive layers on both sides is applied so as to cover the second through hole 161 of the reinforcing plate 160 before installation. In this case, when the first fastener 50 passes through the first through hole 111 and the second through hole 161, the first fastener 50 is screwed in while entangled with the waterproof tape, thereby improving waterproofing. Note that butyl tape with adhesive layers on both sides is preferable as the waterproof tape.

Figure 4 shows the state where the reinforcing metal fittings 100 are attached to the cross plate 30, and Figure 5 shows the state where the reinforcing metal fittings 100 are attached to the cross plate 30 and then the ridge wrap 40 is placed over it. After the reinforcing metal fittings 100 are placed to cover the cross plate 30, the first fastener 50 is driven into the top of the reinforcing metal fittings 100. The ridge wrap 40 is then placed over it, and the second fastener 60 is driven into the side surface 31 on the eaves side of the cross plate 30. If nails or the like were driven from above after the ridge wrap 40 is placed over it, rain or the like would get in through the nailed area and cause the ridge wrap 40 and cross plate 30 to deteriorate, so the first fastener 50 is driven into the cross plate 30 from above the reinforcing metal fittings 100. In addition, the second fastener 60 is driven through the ridge wrap 40 and into the eaves side surface 31 of the side panel 120, fastening the ridge wrap 40, the reinforcing metal fitting 100, and the crosspiece 30.

Also, as can be seen from FIG. 5, the bottom plate 150 of the reinforcing bracket 100 is not completely hidden by the ridge wrap 40, but rather protrudes from the ridge wrap 40. This is because the bottom plate 150 of the reinforcing bracket 100 is configured to protrude, which more reliably prevents rain and other elements from entering. If the bottom plate 150 were short and completely hidden by the ridge wrap 40, there would be a possibility that rain and other elements would sneak in through the bottom of the ridge wrap 40, but if the bottom plate 150 is configured to protrude, rain and other elements will flow toward the eaves side of the roof via the bottom plate 150.

Next, a ridge construction method using the reinforcing metal fittings 100 will be described. The sheathing boards 70 and roofing material 20 are installed on both sides of the ridge beam 10, and the crosspiece 30 is placed on the roofing material 20 in the longitudinal direction of the ridge of the roof. The crosspiece 30 is then fixed with nails or the like after being placed on both sides of the roof sandwiching the ridge beam 10. Then, waterproof tape is applied to cover the second through hole 161 of the reinforcing metal fittings 100, the reinforcing metal fittings 100 are placed to cover the crosspiece 30, and the first fastener 50 is driven from the top of the reinforcing metal fittings 100 toward the ridge beam 10. At this time, the first fastener 50 is driven so as to pass through the first through hole 111 and the second through hole 161 of the reinforcing metal fittings 100. The ridge wrap 40 is then placed so as to wrap both the crosspiece 30 and the reinforcing metal fittings 100, and the second fastener 60 is driven from above the ridge wrap 40 so as to penetrate the side panel 120 and fixed. When driving in the second fastener 60, drive it in so as to connect the ridge wrap 40, reinforcing metal fittings 100, and crosspiece 30.

Second Embodiment
Next, in a second embodiment of the present invention, a reinforcing metal fitting 200 of another form will be described. Fig. 6 is a perspective view showing the reinforcing metal fitting 200 of another form, and Fig. 7 is a view showing the plan, front, and side views of the reinforcing metal fitting 200 of another form. Note that the same reference symbols are used for Fig. 6 and Fig. 7, and detailed descriptions thereof will be omitted.

The reinforcing metal fitting 200 is arranged between the cross-piece 30 and the ridge wrap 40, which are arranged in the longitudinal direction of the ridge of the roof, to reinforce the ridge wrap 40. The reinforcing metal fitting 200 is equipped with an upper plate 110 arranged on the upper surface of the cross-piece 30, and a side plate 120 arranged along the side surface 31 on the eaves side of the cross-piece 30, and the upper plate 110 and the side plate 120 are formed at an angle of approximately 95° as θ3. Note that an angle of 85° to 105° is preferable for θ3. The reinforcing metal fitting 200 is formed by bending, and the metal plate is doubled. Note that the back surface formed by bending is the reinforcing plate 160. The surface of the upper plate 110 of the reinforcing metal fitting 200 has a first through hole 111 for passing a first fastener 50 for fastening the through plate 30 and the reinforcing metal fitting 200, and the reinforcing plate 160, which is the back surface of the upper plate 110, has a second through hole 161 larger than the first through hole 111. In addition, a third through hole 210 is provided in the side plate 120. After placing the reinforcing metal fitting 200 on the through plate 30, it can be fixed more firmly by driving a nail or the like into the third through hole 210.

In addition, the reinforcing metal fitting 200 of a different form can be used in the same way as the reinforcing metal fitting 100. Therefore, the ridge construction method according to the present invention can be carried out by using the reinforcing metal fitting 200 of a different form instead of the reinforcing metal fitting 100, and the ridge structure according to the present invention can also be constructed.

As described above, when the reinforcing metal fitting 100 according to the present invention is used, the strength of the ridge wrap 40 can be improved by more firmly fixing the cross plate 30 and the reinforcing metal fitting 100. On the other hand, when a different type of reinforcing metal fitting 200 is used, it can be easily placed by the cross plate 30 during construction, so a ridge construction method that can shorten construction time can be realized.

The use of the reinforcing metal fittings of the present invention makes the ridge wrap at the ridge section a stronger structure, and is particularly useful for ridge construction methods and ridge structures that use slate roofing materials.
