Description

The present invention relates to roof mounting hardware used to attach roofing materials to mounting parts such as roof underlayment.

A folded-plate roof is installed by attaching a roof mounting bracket called a tight frame to the roof base material, such as a steel frame, placed on the ceiling, and then attaching the folded-plate roof material to the top of this tight frame via a retaining clip.

A known conventional tight frame has legs at the bottom of a tall frame body for placing and fixing it on the roof base material, and a retaining clip fixing part at the top of the frame body for fixing the retaining clip that fastens the folded roof material.

Furthermore, this type of tight frame also has a simple structure that is constructed by bending a single metal plate of a specified shape (see, for example, Patent Document 1 below).

Publication No. 8-5217

The present invention relates to an improvement to roof mounting brackets constructed by bending a single metal plate, as described in Patent Document 1 above, and provides a roof mounting bracket with excellent practicality that can exhibit extremely high strength with a simple structure.

The gist of the present invention will be explained with reference to the attached drawings.

In a roof mounting bracket, a roof material support part 4 capable of supporting a roof material 5 is provided on an upper part of a bracket body 2 having a leg part 3 that is attached to a mounting part 1 such as a roof underlayment 1,
The metal fitting body 2 is composed of a single metal plate A, and this metal plate A is formed in a shape in which a front side plate portion 6 and a rear side plate portion 7 are bent in opposite directions to each other to form a substantially Z-shape in a plan view,
This metal fitting main body 2 relates to a roof mounting fitting characterized in that the lower end of the front side plate portion 6 and the lower end of the rear side plate portion 7 are bent horizontally, and both the front and rear horizontally bent lower ends are configured as the legs 3, and the lower end of an intermediate plate portion 8 located between the front side plate portion 6 and the rear side plate portion 7 is placed on both legs 3, so that the intermediate plate portion 8 is supported by both legs 3.

The roof mounting bracket according to claim 1 is characterized in that the bracket main body 2 is formed in an approximately Z-shaped configuration in a plan view, with the front plate portion 6 bent at a right angle to the intermediate plate portion 8, and the rear plate portion 7 bent at a right angle to the intermediate plate portion 8 in the opposite direction to the front plate portion 6 .

Since the present invention is configured as described above, the roof mounting bracket can be used to mount the roof material to the mounting section, and since the bracket body is constructed by bending a single metal plate, it is possible to easily design and realize a bracket body with legs that ensures stable installation to the mounting section (roof underlayment, etc.) and welding allowance using existing processing techniques such as metal press processing. In addition, since the bracket body is formed in a roughly Z-shape in plan view and has a reinforcing structure due to bending, it is able to demonstrate extremely high resistance to pressure applied from above the roof through the roof material, pressure applied from below the roof due to wind blowing up, and lateral pressure that tries to topple the bracket body, making it an extremely practical roof mounting bracket that can be used to construct a high-strength roof structure.

In addition, in the present invention, the lower end of the front plate portion and the lower end of the rear plate portion of the bracket main body are bent horizontally and both the front and rear horizontally bent lower ends are configured as the legs, thereby ensuring sufficient stability of installation to the mounting portion by both legs and also ensuring a sufficient welding allowance to the mounting portion, resulting in a roof mounting bracket with a more practical configuration.

In addition, in the present invention, the main body of the bracket is provided with a reinforcing structure in which the lower end of the intermediate plate portion is supported on the leg portion, resulting in a roof mounting bracket with an extremely practical configuration that can exhibit even higher resistance to deformation strength.

In the invention according to claim 2 , the roof mounting bracket has a structure that is even more practical, since the bracket body that reliably exerts the above-mentioned functions and effects can be easily designed and realized with a simple structure.

FIG. 1 is a perspective view showing the present embodiment. FIG. 11 is a perspective view showing the present embodiment from a different angle (rear side). FIG. 1 is a plan sectional view showing the present embodiment. FIG. 2 is an explanatory front view showing the present embodiment with a portion cut away and the cut-out portion enlarged. FIG. 2 is a development view showing a metal plate of the present embodiment. FIG. 2 is a schematic explanatory perspective view showing a state in which the present embodiment is used.

The optimal embodiment of the present invention will be briefly explained with reference to the drawings, showing the operation of the present invention.

In the roof mounting bracket of the present invention, the bracket body 2 is attached to a mounting portion 1 such as a roof underlayment 1 via the legs 3. When a roof material 5 is attached and supported to the roof material support portion 4 on the upper part of the bracket body 2 attached to this mounting portion 1, the roof material 5 is laid on the mounting portion 1 via this roof mounting bracket.

The roof mounting bracket of the present invention has the bracket body 2 made of a single metal plate A, and this metal plate A is not simply a flat plate, but has a front side plate portion 6 and a rear side plate portion 7 bent in opposite directions to form a roughly Z-shape in a plan view. Furthermore, the lower end of the bracket body 2 (metal plate A) is bent horizontally, and this horizontally bent lower end constitutes the leg portion 3.

Therefore, the metal fitting body 2 with the legs 3 can be easily designed and realized by processing a single metal plate A using existing processing techniques such as metal press processing.

The metal fitting body 2, which is bent in a roughly Z-shape when viewed from above, is a reinforcing structure with resistance to deformation caused by bending, and therefore has extremely high resistance (resistance to deformation) to loads (pressures) applied from above the roof through the roofing material 5, loads (pressures) applied from below the roof due to wind blowing upward, and lateral loads (pressures) that attempt to topple the metal fitting body 2. Therefore, a roof structure installed using this roof mounting metal fitting has high strength.

The metal fitting body 2 has a leg 3 formed by the horizontally bent lower end of the metal plate A, and the stability of the installation on the mounting part 1 is ensured via this leg 3, and this leg 3 can also be used as a welding allowance for the mounting part 1.

Specific examples of the present invention will be described with reference to the drawings.

The roof mounting bracket of this embodiment is applied to a system tight frame used for insulated folded-plate roofs, and has a roof material support part 4 capable of supporting and mounting a folded-plate roof material 5 on the upper part of the bracket body 2 equipped with legs 3 that are attached to a mounting part 1 (in this embodiment, the mounting part 1 will be referred to as the roof base material 1 in the following description) such as a roof base material 1 (steel frame), and furthermore, a joiner receiver 20 (see Figure 6) is provided on the lower side of this bracket body 2 via a mounting hole 21.

The insulated folded-plate roof using this system tight frame is described below. As shown in FIG. 6, a number of metal fittings 2 are fixed (welded) to the roof base material 1 at intervals in the left-right direction, which is the length direction of the roof base material 1, in an upright state via the legs 3. A T-shaped joiner 19 with an inverted T-shaped cross section is connected and supported to the joiner receiver 20 of each metal fitting 2 fixed at intervals. A thermal insulation material 9 is laid between adjacent joiners 19 at intervals in the left-right direction, and a folded-plate roof material 5 is fastened to the roof material support part 4 on the top of the metal fittings 2 via a retaining clip 11 to form a roof structure. In the following, in this embodiment, the direction corresponding to the length direction of the seam 10 of this insulated folded-plate roof is defined as the front-rear direction of this roof mounting metal fitting.

Although not shown, this embodiment can also be applied to tight frames that are not for systems or tight frames for eaves, and can also be applied to roof mounting brackets other than tight frames (for folded plate roofs).

Specifically, the metal fitting body 2 in this embodiment is composed of a single upright metal plate A that has a length in the vertical direction, and this metal plate A is formed so that the front side plate portion 6 and the rear side plate portion 7 are bent in opposite directions to each other, forming an approximately Z-shape in a plan view.

More specifically, the metal plate A is used in a predetermined vertically elongated expanded shape as shown in FIG. 5, and the front plate 6 is bent at a right angle to the intermediate plate 8 along the first vertical fold edge 12 in the leftward direction in FIG. 1, while the rear plate 7 is bent at a right angle to the intermediate plate 8 along the second vertical fold edge 13 in the opposite direction to the front plate 6 (the rightward direction in FIG. 1). As a result, the metal fitting body 2 is formed in a generally Z-shape in plan view, in which the front plate 6, which has a surface in the left-right direction, the intermediate plate 8, which has a surface in the front-to-back direction, and the rear plate 7, which has a surface in the left-to-right direction, are connected (connected) in the front-to-back direction, as shown in FIG. 3.

The metal fitting body 2 thus constructed is a reinforcing structure with deformation resistance strength due to bending, and therefore is not only extremely strong (deformation resistance strength) against loads (pressures) applied from above the roof through the roofing material 5, or loads (pressures) applied from below the roof due to wind blowing up, but is also extremely strong (deformation resistance strength) against lateral loads (pressures) that tend to topple the metal fitting body 2 (particularly the intermediate plate 8 can withstand loads (pressures) that tend to topple the metal fitting body 2 in the front-to-back direction, particularly the front plate 6 and rear plate 7 can withstand loads (pressures) that tend to topple the metal fitting body 2 in the left-to-right direction, and the entire metal fitting body 2 (the intermediate plate 8, front plate 6, and rear plate 7, which are connected in a roughly Z-shape in plan view) can withstand loads (pressures) that tend to topple the metal fitting body 2 in the front-left diagonal direction, front-right diagonal direction, rear-left diagonal direction, and rear-right diagonal direction).

In addition, the metal plate A constituting the fitting main body 2 is formed in a shape in which the lower end of the front plate portion 6 and the lower end of the rear plate portion 7 protrude downward further than the lower end of the intermediate plate portion 8 (see FIG. 5 ), and the lower end of this front plate portion 6 is bent horizontally rearward along a first horizontal folded edge 14, and the lower end of the rear plate portion 7 is bent horizontally forward along a second horizontal folded edge 15, so that both of these horizontally folded lower end portions are arranged side by side on the left and right sides of the intermediate plate portion 8, and these horizontally folded lower end portions arranged side by side on the left and right sides are configured as the legs 3.

Furthermore, the left and right legs 3 are butted at their respective parallel ends, and the lower end of the intermediate plate 8 is supported on both butted ends. In other words, as shown in FIG. 4, about half of the plate thickness of the lower end of the intermediate plate 8 (the left half in the figure) is placed and supported on the butted end of one leg 3A that is continuous (connected) with the front plate 6, and the other half of the plate thickness of the lower end of the intermediate plate 8 (the right half in the figure) is placed and supported on the butted end of the other leg 3B that is continuous (connected) with the rear plate 7. This reinforcing structure in which the intermediate plate 8 is supported by the legs 3 (3A and 3B) is configured to provide extremely high resistance (deformation resistance) to lateral loads (especially loads from the front and rear directions) that tend to topple the metal fitting body 2.

Although not shown, either the lower end of the front plate portion 6 or the lower end of the rear plate portion 7 may be bent horizontally and this horizontally bent lower end may be configured as the leg portion 3, or the lower end of the intermediate plate portion 8 may be bent horizontally and this horizontally bent lower end may be configured as the leg portion 3.

In addition, the metal plate A is formed in a shape such that the upper end of the front side plate portion 6 and the upper end of the rear side plate portion 7 protrude upward further than the upper end of the intermediate plate portion 8 (see Figure 5), and the upper end of the front side plate portion 6 is bent horizontally rearward at a right angle along the third horizontal fold edge 16, and the upper end of the rear side plate portion 7 is bent horizontally forward at a right angle along the fourth horizontal fold edge 17, so that both of these horizontally bent upper ends are configured as the roof material support portion 4.

In addition, the roof material support part 4A connected to the front side plate part 6 and the roof material support part 4B connected to the rear side plate part 7 are arranged at a higher position than the other roof material support part 4B by making the folding positions (the height of the third horizontal folding edge 16 and the fourth horizontal folding edge 17) different vertically. The roof material support part 4A at the higher position (one side) can directly support the underside of the peak part of the folded plate roof material 5 on its upper surface, and the roof material support part 4B at the lower position (the other side) has a mounting bolt 18 in an upright state, and the retaining clip 11 can be fixed to its upper surface by the mounting bolt 18 (the other roof material support part 4B is configured as a retaining clip mounting part 4B), and the folded plate roof material 5 can be indirectly supported on the roof material support part 4B via the retaining clip 11. The reference numeral 25 in the figure is a bolt hole for mounting the mounting bolt 18.

To explain this roof material support part 4 in more detail, one of the roof material support parts 4A is configured so that the edge on the side adjacent to the intermediate plate part 8 is supported on the upper end part of the intermediate plate part 8, and this roof material support part 4A is configured to exhibit high deformation resistance strength against the load (pressure) applied from above to the folded plate roof material 5.

The other roof material support part 4B has an edge formed on the side facing the intermediate plate part 8 as an uneven edge 22, and several (two in the drawing) support holes 24 into which the convex edge parts 23 are inserted are provided (formed through) at several places (two in the drawing) on the upper side of the intermediate plate part 8 corresponding to the multiple (two in the drawing) convex edge parts 23 of the uneven edge 22. For example, first, the upper end part of the rear side plate part 7 is bent along the fourth horizontal folded edge 17 to form the low-position (other) roof material support part 4B, and then the rear side plate part 7 is bent along the second vertical folded edge 13, so that the multiple convex edge parts 23 are inserted and supported in the multiple support holes 24, and this roof material support part 4B is configured to exhibit high deformation resistance strength against the load (pressure) applied from above and below to the folded plate roof material 5 via the retaining clip 11.

The present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
