[Problems to be Solved by the Invention] However, conventionally, since the purlin of the roof panel is fixed to the truss upper chord member of the shed structure with bolts at a large number of points, a lot of man-hours are required for the bolt fastening work, and the roof is required. Since the bolts had to be tightened inside the hut after the panel had been hung up, the worker who had hung up on the roof then either went to the hut or made the worker wait in advance in the hut. I had to keep it.

Further, conventionally, since the purlins are simply fixed to the existing truss upper chords by bolts, it is necessary to separately connect the roof panels to each other. From this point as well, many roof construction works are required. It took a lot of work. The present invention is
In view of this situation, it is possible to reduce the work time by installing the roof panel on the roof structure without bolting work in the back of the shed, and at the same time connecting the roof panels to each other at the same time. To aim.

[Means for Solving the Problems] In order to achieve the above object,
The present invention has taken the following technical means. That is, the present invention comprises a roof panel in which a purlin is fixedly attached to the lower surface of a base plate, and a truss upper chord member in the roof flow direction which constitutes a shed structure, and the purlin is fixed so as to be orthogonal to the truss upper chord member. In the roof panel mounting structure, a locking member that locks the lower section of the purlin and restricts the downward movement of the purlin in the roof flow direction is provided on the truss upper chord member. It is characterized in that a connecting means for connecting the roof panel to the one roof panel on the downstream side in a flush manner is provided when the roof panel is hooked on the stop member.

Specifically, the purlin has a lateral flange portion at the bottom of its cross section, and the hooking member projects from the upper surface of the upper chord member of the truss with a hook portion directed upward in the roof flow direction. A portion is fitted between the hook portion and the upper surface of the truss upper chord member. Further, when the roof panel has a purlin at the lower edge of the base plate, the connecting means can be composed of a hanging bracket fixed to the side surface of the downstream roof panel purlin. In this case, the hanging bracket and the truss are connected. The flange portion of the purlin of the upstream roof panel is fitted between the upper chord member and the upper surface of the upper chord member.

As another connecting means, a connecting fitting having an upper hooking claw facing upward in the roof flow direction and a lower hooking claw facing downward in the same direction can be formed by projecting from the upper surface of the truss upper chord member. , The flange part of the purlin of the roof panel on the downstream side is fitted between the lower hook and the upper surface of the truss upper chord, and the flange of the purlin of the roof panel on the upstream side of the upper hook and truss upper chord It is fitted between the upper surface.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 show a first embodiment of the present invention. In FIG. 3, a plurality of beam members 2 made of H-shaped steel are laid in parallel with each other on the upper ends of a large number of large columns 1, and a plurality of trusses 3 are mounted on the beam members 2 in the longitudinal direction of the beam members 2. The shed assembly 4 is configured by arranging the rows in a row.

The truss 3 is framed in the form of an isosceles triangle from a horizontal lower chord member 5 and a truss upper chord member 6 which is inclined in the roof flow direction, and its construction surface is a large or small pillar member 7 provided in the middle of the lower chord member 5. And the lower chord member 5 and the truss upper chord member 6 are formed by joining the back sides of C-shaped steel to each other. The truss upper chord members 6 are I type, H type,

The roof panel 9 hung by the rope 13 is hung on the roof frame 4 as shown in FIG.
The purlin 11 is fixed so as to be orthogonal to the upper chord member 6 of the truss, and is connected flush with the adjacent roof panel 9, so that the roof surface of the building is built on the roof frame 4. In addition,
In the case of the present embodiment, since the hanging metal fitting 22 described later is fixed to the side surface of the purlin 11, it is not necessary to form the elongated hole 12 on the side where the hanging metal fitting 22 is provided.

In the illustrated roof panel 9, a waterproof sheet (for example, asphalt roofing) is provided on the upper surface of the base plate 10.
12A is laid, and a flat roof tile 13A is roofed on the waterproof sheet 12A. Therefore, when the roof panels 9 are connected flush with each other on the roof frame 4, the subsequent construction on the roof is only roofing at the joint portion of the roof panels 9.

The roof panel 9 has only the purlin 11 fixed to the lower surface of the base plate 10, or the waterproof sheet 12A.
The purlin 11 may be fixed to the lower surface of the base plate 10 having the above structure, but in that case, it is necessary to perform the construction of the waterproof sheet 12A and the roof tile 13A at the site after the panels are joined. The purlin 11 is made of C-shaped steel having a horizontal flange portion 15 at the upper and lower portions of its cross section, and a vertical lip portion 16 is formed at the tip of the flange portion 15. As the purlin 11, a member made of I-type or H-type steel or hard resin in addition to C-type steel can be adopted.
It suffices that a lateral flange portion 15 is formed on the lower portion of the cross section so as to hook the lower portion of the cross section.

A purlin 11 is provided on the upper surface of the truss upper chord member 6.

At this time, since the upper plate portion 19B of the hook portion 19 is inclined upward, the lip portion 16 of the purlin 11 can be easily fitted into the hook portion 19. Also, the upper plate portion 19
Since the upper end of the lip 16 is pushed down at the base of B,
After the roof panel 9 is attached, the purlin 11 is pressed against the upper surface of the truss upper chord member 6. The mounting plate portion 18 can be fixed to the upper surface of the truss upper chord member 6 by welding. However, when the mounting plate portion 18 is fixed by the bolts 20 as in this embodiment, for example, the bolt insertion holes of the mounting plate portion 18 are arranged in the roof flow direction. The long elongated hole has an advantage that the position of the hooking member 17 in the roof flow direction can be adjusted.

Further, in this embodiment, the hanging metal fitting 22 is fixed to the outer surface of the purlin 11 provided at the edge of the base plate 10, and the hanging metal fitting 22 locks the purlin 11 of the roof panel 9. A connecting means 40 is provided to connect the roof panel 9 to the roof panel 9 on the downstream side in a flush manner when the member 17 is hooked. This hanging bracket 22
Has a suspension plate 24 having an insertion hole 23 therein and provided upright at the center of a rectangular mounting plate 25. The mounting plate 25 is fastened to the side surface of the purlin 11 with bolts 26, whereby the suspension plate 24 is It is attached so as to project outward from the side surface of the purlin 11.

At the mounting position of the hanging metal fitting 22, the height from the lower edge of the mounting plate 25 to the lower surface of the purlin 11 is the purlin 11.
The height of the lip portion 16 is set to be the same as that of the lip portion 16. Therefore, when the upstream roof panel 9 is abutted against the existing downstream roof panel 9 as shown in FIG. 2A, it is fixed to the downstream roof panel 9 as shown in FIG. 2B. Attaching plate 25 of hanging metal fitting 22 and truss upper chord member 6
The lip 16 of the purlin 11 of the upstream roof panel 9 is fitted between the roof panel 9 and the upper surface of the roof panel 9 so that the roof panels 9 are connected flush with each other.

In the case of constructing a roof of a building using the mounting structure having the above structure, as shown in FIG. 1, first, the hook members 4 are attached to the upper surface of the truss upper chord member 6 at predetermined positions. The roof panel 9 is hung above, the purlin 11 is once placed on the truss upper chord member 6, and the roof panel 9 is slid to the downstream side in the roof flow direction.

Then, the lip portion 16 of the purlin 11 is fitted between the hook portion 19 of the hooking member 17 and the upper surface of the truss upper chord member 6, whereby the bolt fastening work in the attic which has been conventionally required. The roof panel 9 can be easily attached to the truss upper chord member 6 without performing the above. On the other hand, as shown in FIG. 3, the roof panel 9 is mounted from the downstream side in the roof flow direction. At this time, when the roof panel 9 to be mounted is connected to the existing roof panel 9 on the downstream side, As shown in (a), the purlin 11 of the existing roof panel 9 is abutted against the purlin 11 of the existing roof panel 9.

Then, as shown in FIG. 2 (b), the lip portion 16 of the purlin 11 of the upstream roof panel 9 is fitted between the mounting plate 25 of the hanging fitting 22 and the upper surface of the truss upper chord member 6. As a result, the roof panels 9 can be connected flush with each other at the same time as the truss upper chord member 6 is attached, and from this point as well, the labor can be reduced. Further, in this embodiment, the hanging metal fitting 22 is adopted as the connecting means 40, and the metal fitting 22 has not only the connecting function of the roof panel 9 but also the hanging function thereof, which is an advantage that the number of parts is reduced. There is also.

Next, FIGS. 5 and 6 show a second embodiment of the present invention. In this embodiment, the hook member 17 is the same as that of the first embodiment, but the connecting means 40 is a steel plate detachably attached to the truss upper chord member 6 unlike the case of the first embodiment. It is composed of a connecting metal fitting 27. As shown in FIG. 5, the connecting fitting 27 has hooking claws 28 and 29 formed by bending the upper center side and both sides in opposite directions, and a hooking recess 30 having a trapezoidal cut in the side center. The hooking concave portion 30 is attached to the truss upper chord member 6 by being hooked on the upper lip portion 31 above the cross section of the truss upper chord member 6.

At this time, one of the hooks (top hook)
28 is directed to the upper side of the roof flow direction, and the other hooking claw (lower hooking claw) 29 is directed to the lower side of the roof flow direction. From the upper surface of the truss upper chord member 6 of these hooking claws 28 and 29. The formation position of the hook recess 30 is set so that the height of the hook is the same as the height of the lip 16 of the upper chord member 6 of the truss.

Therefore, as shown in FIGS. 5 and 6, after the connecting metal fitting 27 is set so that the lower hook claw 29 is hooked on the lip portion 16 of the roof panel 9 on the downstream side, the roof panel 9 on the upstream side is set. By fitting the lip portion 16 between the upper hook 28 and the upper surface of the truss upper chord member 6, it is possible to connect the vertically adjacent roof panels 9 to each other so as to be flush with each other.

Incidentally, also in this embodiment, the hooking member 17
Since the roof panel 9 can be attached to the truss upper chord member 6 simply by hooking the purlin 11 to the truss upper chord member 6, the roof panel 9 can be easily attached to the truss upper chord member 6 without performing bolt fastening work in the attic which has been conventionally required. And the roof panels 9 can be connected flush with each other at the same time as the attachment to the truss upper chord member 6 by the connecting fitting 27.

Further, in the case of the present embodiment, it suffices to hook the connecting metal fittings 27 on both the truss upper chord member 6 and the purlin 11, and fixing work such as bolt fastening to the purlin 11 as in the first embodiment. Since there is no need to apply it, there is an advantage that the labor of processing the connecting means 40 is reduced. Next, FIG. 7 and FIG.
Shows a third embodiment of the present invention.

In this embodiment as well, the hook member 17 is the same as that in the first embodiment, but the connecting means 40 is different from the first and second embodiments in that one end surface of the roof panel 9 is different. And a connecting hole 33 formed in the other end surface of another roof panel 9 connected to the roof panel 9.
