Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a roof structure using a metal partition roofing material and its support structure, and more specifically, to a roof structure using a metal partition roofing material and a supporting structure thereof, and more specifically, to This invention relates to a roof structure that improves rain protection at the joint end and prevents the joint end from lifting off from the lower plate.

[Conventional technology]

Roofing with metal roofing materials (The challenge with roofing is to improve the rain protection
There is no lifting of the face plate from the lower plate such as wood wool board, and it reduces noise caused by rain, maintains fire resistance, and improves rigidity against loads, and has a design comparable to that of tiled roofs. It's about making it work.

In order to create a joint structure that improves rain protection, the inventor of the tree first raised the eaves side edge of the face plate, bent the horizontal part continuous to the raised edge inward, and to form a horizontal part and a holding part continuous to the front edge of the raised end, and form these face plates as a unit from the eave side to the ridge side to form the ridge side edge and eave side edge of each face plate, respectively. By aligning the horizontal parts, they are overlapped with a relatively large step, and on the inside of the overlapping surface,
The present invention proposes an invention in which the eave-side holding part at the edge of each horizontal part is wrapped around the ridge-side bending part to create a ribbed structure. With this structure, the joining surfaces of each face plate are joined at the falling and rising parts of the predetermined step, and a joining line is formed by overlapping the two in a floating state above the eaves side plate, so it is possible to avoid heavy rain. Even when rain is blown up by typhoons and other events, we have achieved a track record that there is no intrusion of rainwater from the bonded surfaces. In addition, the appearance is similar to that of a tiled roof due to the steps at the joints, and the layers are stacked with deep steps, and the steps are horizontally continuous straight lines or curves, so the design is different from that of conventional metal roofs. A much better effect was obtained.

[Problem that the invention seeks to solve]

However, in this structure, since the lower board is generally laid flat on the rafters, each face board has a step area slope rather than a vine root slope, and there is a problem with the wood quality that it floats up from the lower slope. In other words, if it is installed in a floating state, it will cause noise due to rain and deformation due to load.

As a countermeasure against this problem, a wedge-shaped cross section may be used depending on the uplift slope of the lower surface. However, in reality, such a shape is difficult to manufacture and is expensive. Moreover, the lower plate is not only a lining material, but also a strength member, a heat insulator, and a j! Needless to say, the wedge shape is not suitable for these purposes.

By the way, recently residential and large-scale i! In addition to simply insulating dyed textiles, we also have systems that circulate airflow inside and outside the building to optimally adjust the thermal Oa ring to save energy, structures that utilize the attic, and systems that extend to the apex of buildings. A structure with an atrium has been developed. In other words, there is a need for the support structure of the roof to not only function as a structural member in terms of strength, but also to have functions that are compatible with these structures.

Therefore, the purpose of this invention is to provide a robust roof structure with no gap between the face plate and the bottom plate, in addition to the advantages of the roofing material previously developed by the present inventors, such as improved rain protection and design effects. The object of the present invention is to provide a roof structure that supports the roof structure and is fully compatible with various advanced technologies.

[Means for solving problems]

In order to achieve the above object, the roof structure of the present invention includes a lower plate that is fixed to a roof support structure and is continuously stacked in a talin car shape from the eave side to the ridge side, and a stack of flagstones on each lower plate. A roof consisting of a metal face plate with a raised edge, the edge of the face plate on the eaves side is lowered, and the horizontal part continuous to the edge of the eaves is bent inward, while the edge of the face plate on the ridge side is raised. A horizontal part and a holding part are formed that are continuous with the front edge of the raised F end, and a
, overlap the ridge side edges and eave side edges of adjacent face plates with a thickness approximately equal to the thickness of the lower plate by matching the horizontal parts formed respectively, and on the inside of the overlapping surfaces, each horizontal part The front edge of the eaves side holding part is wrapped around the ridge side bending part to form a loose joint.

In addition, the roof support structure of the present invention includes a lower plate fixed on the roof support material and continuously stacked in a talin car shape from the eave side to the ridge side, and a metal plate with talcum laminated on each lower plate. A base plate consisting of a face plate, in which the eave side edge of the face plate is lowered, and a horizontal part continuous to the lowered edge is bent inward, while the ridge side edge of the face plate is raised, and the eave side edge of the face plate is raised, Forming a continuous horizontal part and a holding part on the front edge of the raised end,
At the overlapping edge of each bottom plate,! 4. Ridges of adjacent face plates [edges and eave side edges are overlapped with a thickness that is approximately τ equal to the thickness of the lower plate by matching the water parts formed respectively, and 1. By wrapping the eaves-side holding part at the leading edge of the roof into the ridge-side bending part. It is an A-bonded roof structure, and is characterized in that an air layer is formed between the base material laid on the main building and the base material laid under the face plate.

[Effect]

The lower plate has a uniform thickness and is flush with the surface of the face plate, so there is no lifting of the face plate, improving rigidity against loads and i! ! It provides sound and insulation properties, and the RI or rafters or both are lightweight, and can be freely used for wiring, piping, or air passages through the hollow holes.

There is a circular hole (2a) on the side of the rafter (2).
Lightening holes, that is, through holes formed by a combination of the long holes (2b) and the elongated holes (2b) are formed at appropriate regular intervals.

The rafters (2) are perpendicular to the rafters (2) and have a plurality of lower boards (4) that form the base material made of wood wool boards, etc. of the horizontal roofing material (3), which is elongated in the direction perpendicular to the plane of the paper, at the eaves. From the side to the ridge, they are stacked one on top of the other with a predetermined overlap margin (1), and the rear ends are fixed to the rafters (2 inches) with hangers (5).

A face plate (6) is closely fixed to the upper surface of each lower plate (4), and the edge of the eaves side of the eight-sided plate (8) is the light! Joint parts (7) and (8) that engage with each other are formed on the fi edge and the ridge side edge, that is, the rear edge, respectively, and these are connected from the eaves side to the ridge side, with each face plate (6) as one unit. They are connected sequentially.

This joint structure is shown in an enlarged view in Fig. 2. Among these, the tip joint part (7) connects the crown part (71) to the eave-side protruding end from the lower plate (4) of the face plate (6) slightly diagonally outward and downward. A hanging portion (72) that is bent to a predetermined length and the end thereof is bent downward.
, a water upper part (73) with the lower edge of the lower edge of the vertical part (72) bent inward, and an internal standing part (74) with the end of the horizontal part (73) bent upward. Standing part (74
) is bent at the top of the second horizontal part (75) facing further inward.
) and an engaging raised part (76) formed by bending the end of the water tube part (75) are continuously formed.

Further, the rear end joint portion (8) includes a rising portion (81) that abuts against the falling portion (72) at the rear end of the face plate (6).
) and the above-mentioned No. 1. The first horizontal part (82), the internal standing part (83) and the second horizontal part ( 84), a holding part (85) that is folded back in a substantially U-shape from the end of the second horizontal part (84) and surrounding the protrusion (76), and a curved end of the holding part (85). It consists of a segmented protrusion (86) formed therein.

The above-mentioned joints (7) and (8) are obtained by drawing both longitudinal ends of a long color steel plate, which is the material for forming the face plate (6), using a roll forming machine or the like.

The hanger (5) is a press-formed body of thick steel plate, and as shown in FIG. A horizontal part (53) extending horizontally at one end of the rising step wall part (52) and the first step wall part (52), and an insertion part (54) formed in a curve at the end of the horizontal part (53), respectively. It consists of a pair of reinforcing ribs (55) protrudingly formed at the corners of.

The height of the stepped wall portion (52) approximately corresponds to the thickness of the lower plate (4), and the horizontal portion (53) sets the overlapping margin (1) of the overlapping surfaces of each lower plate [4]. , furthermore, the insertion part (54) is connected to the holding part (85) and the division protrusion (8).
6), supporting the joint ends of the face plates (6).

In the above configuration, the main part of each face plate (6) is the lower plate (
4], only a narrow space is formed at the front edge of the joint end of the lower plate (4), and the thickness of the lower plate (4) that backs up the face plate is uniform, so it has high rigidity. It also has excellent heat insulation, sound insulation, and fire resistance properties.

Further, since the horizontal plane that is the abutting surface of the joints (7) and (8) has a two-step staircase shape, the path for rainwater to enter becomes even more maze-like, making it extremely difficult for rainwater to enter.

In addition, piping and wiring can be freely inserted into and pulled out from inside the rafter (2) through the circular hole [2a] or the long hole (2b), as well as through holes such as the circular hole (2a) or the long hole (2b). It can also be used as an air circulation hole, making it more compact in appearance.

Figure 5 shows a modification of the support structure in the built-in example, in which field materials (lO) made of fiberboard etc. are buried between the rafters (2) and supported on the main building (1). There is.

In this example, since the field material (1O) is porous, it functions as a shielding plate, and the first embodiment can further improve the heat insulation and sound insulation properties.

Fig. 6 shows an example of shape modification of the joint parts (7) and (8) of the face plate (6). In order to avoid confusion with the first embodiment, each part of the joint parts (7) and (8) is Let's explain by changing the sign.

The tip side joint (7) is the tip of the face plate (6) and the front side plate (
6), a first horizontal portion (72a) bent inward from the falling portion (71a), and a portion of water (72a) A rising part (73a) rising from the tip of the rising part (73a) and a rising part (73a) rising from the tip of the
The second horizontal part (74a) is bent horizontally at the tip of the second horizontal part (73a).
), and a retaining protrusion (75a) which is formed by bending the end of the second horizontal part (4a).

The rear end joint portion (8) includes a raised portion (81b) bent toward the back of the raised portion (73a), and a raised portion (81).
a U-shaped horizontal part (s2
b), and a segmented protrusion (84b) that is bent back from the distal end of the horizontal portion (82b) and formed in a curve at the distal end of a holding portion (83b) that surrounds the protrusion (7B).

According to this example, the first horizontal part (72a) of the joint (7)
Since is in contact with the surface of the face plate (6), rainwater easily enters the interior due to capillary action. However, the rainwater that has entered through here is trapped in the rectangular space (d) surrounded by the raised parts (73a) and (81b). It stops and there is no further intrusion, and it is properly discharged.

In this way, the joint part (?), (8) can have a large space in the middle part as described above in the step-like labyrinth shown in the first embodiment. In addition, even if it is not the illustrated example, the most effective water-stopping shape can be obtained by repeating experiments and the like.

Figures 7 (A) to (D) show examples of changes in the shape of the hat-shaped steel frame that constitutes the rafters (2); in (A), the flange is located at the lower part, contrary to the first embodiment. In CB), the base of the collar is constricted, and in (C), it is shaped like (
The arrangement is reversed to that in B), and in (D) the top has a two-step protruding shape. Various shapes other than those shown in the drawings can be selected depending on the required strength tonality and the relationship with the mating parts to be attached.

FIG. 8 shows a second embodiment of the present invention.
The same parts as in the embodiment are given the same reference numerals, and only the main parts will be explained.

In the figure, Njl(1) and the rafter (
2) A plurality of shielding plates (100) are interposed over the entire surface between the main building (1) and the rafters (2).
] With the shielding plate (100) in between, thread the bolt (101), screw in the nut (102), and tighten the shielding plate (100).
) is clamped and fixed between them.

Each shielding plate (100) is made of the same material as the base material, ie, the lower plate, such as the wood wool board, and functions as a strength member, as well as a heat insulating material, a sound absorbing material, or a fireproofing material.

Therefore, the lower plate [4] of the roof side (1) and the shielding plate (10
0), an airtight air chamber (103) is formed between the two, and the heat insulation and sound insulation effects are extremely high.
We are also looking forward to future system upgrades, such as creating part of the air flow path within the passive leaf system.

FIGS. 9 and 10 show a third embodiment in which the second embodiment of the edict is further expanded by 51 times. In fig.

The rafters (200) are made of hollow steel frames with a square cross section, and are parallel to the main building (1) and support the shielding plate (100) via poles (101) and nuts. Also,
On both sides of the rafter (200), hollow holes are formed by repeating circular holes (2QOa) and long holes (200b) at appropriate intervals.

Incidentally, the rafter (200) deviates from the definition of a rafter in terms of its original function, but instead, the upper part of the rafter (200) has a shielding function such as senna lily board, hard wood pieces, plywood board, etc. The base material (201) having the following properties is laid down and fixed, and these are used as rafters.The above-mentioned roofing material (3) is laminated in a clinker-like manner from the eaves side to the ridge side on the base material (201), and the rear edge is suspended. It is fixed by the child (5).

According to the above embodiment, double air chambers (202) and (203) are formed, and the insulation properties and j! ! Sound performance and fire resistance are improved, especially in the air chamber (
202) is a separate space for both the inside and outside, so by utilizing this, we can expect a new list of uses as described in the 752 embodiment.

In addition to the above, when the rafters (200) are installed in the same direction as the main building, this rafter has essentially the same effect as the main building, so by changing the direction of the base material (201) that is perpendicular to this, , the roof structure can also be made stronger.

Furthermore, the rafters (200) are not only parallel to the main building, but can also have a wide range of crossing angles, from diagonal to perpendicular, depending on the shape and structure of the roof.

〔Effect of the invention〕

As explained in detail in the following embodiments, in the roof structure of the present invention, the MOI of the lower plate constituting the roofing material is adjusted from the eaves side.
A face plate is closely laminated on the upper surface of each lower plate, and adjacent face plates are joined at the overlapped end edges of the lower plates by matching their vertical and vertical ends and joining them together. Because of this, it has perfect water resistance and has the advantage of being much less aesthetically pleasing, while also having the advantage of high strength and rigidity, and excellent heat insulation, sound insulation, and fire resistance. Furthermore, since the lower plate is a flat plate, manufacturing is easy and costs can be reduced.

In addition, with the roof support structure of this invention, wiring, piping, and ventilation can be carried out inside the hollow of the main building, the tree, or both, and these can be inserted and pulled out from any cutout hole, so wiring and piping under the ceiling can be carried out. This eliminates the clunky condition associated with this, and makes it easy to deal with spaces such as attics and atriums.

Furthermore, as shown in the example, if a shielding plate is inserted between the main building and the rafters, an air chamber is formed between the roofing material and the insulation, sound insulation, and fire resistance effects can be greatly improved. Can deal with air conditioning systems such as air cycle systems used.

It is clear from the above description that the above objects of the present invention are effectively achieved. In addition, since changes can be made to the above configuration without departing from the spirit and scope of Endpoint 1, the above description or all are examples of cars, and should not be interpreted in any limited sense. do not have.

The claims are intended to cover every feature of the invention and all matter of the scope of the invention which may be omitted as a matter of course.
