DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure for metal shingles, and more particularly, to a structure for connecting a metal shingle with straightness in the direction of a ridge in a wing eaves direction while easily performing a construction for achieving a straightness in a ridge direction. Dramatically enhances the watertightness of the connection points, and
The present invention relates to a technique for easily laying a new metal shingle while leaving an existing roof as it is, and making it possible to easily replace the roof.

[0002]

2. Description of the Related Art Conventionally, when a metal shingle is connected in a direction orthogonal to the direction of the roof eaves, a tight frame b is attached to a purlin a as shown in FIG. 8a, the metal roof shingle 1a is attached, and the connection part 1c of the adjacent metal roof shingle 1b is covered.
a and 1b are connected.

[0003]

However, in such a configuration, it is difficult to mount the tight frame b in a straight line with the purlin a, and the tight frame b is In many cases, when the tight frame b is displaced with respect to the direction perpendicular to the eaves direction, the metal shingle 1a
It is difficult to construct the building with linearity in the direction of the eaves. In addition, the tight frame b is spaced apart in the direction of the eaves, so that it is difficult to increase the connection strength of the metal shingles 1a, 1b, and furthermore, it is easy for rainwater to easily penetrate from the connection portion of the metal shingles 1a, 1b. It is.

[0004] On the other hand, when a conventional roof tile roof is replaced with a metal roof, the existing roof material is peeled off, and the number of steps required to replace the roof is greatly increased, and the cost is significantly increased. Had become. The present invention is intended to solve such a problem, and it is possible to easily perform the construction for obtaining linearity in the direction of the eaves in the case of laying a metal shingle while improving the connection strength and the watertightness of the connection portion. It is an object of the present invention to provide a connection structure of a metal roof shingle which can be greatly increased, and a new metal shingle can be easily laid while keeping an existing roof as it is, and the roof can be easily replaced. I do.

And an upright vertical part 22, and the outer surface of the vertical part 22 is the receiving surface 6. At the upper part of the vertical portion 22, an elastic receiving piece 5a bent inward into a substantially U-shape is formed.

Thus, the metal rafters 2 having a substantially inverted U-shaped cross section are arranged on the roof base 9 at an interval in a direction perpendicular to the direction of the eaves. In the embodiment, it is mounted on an existing roof plate). Next, the receiving surface 6 of the connection piece 5 of the metal roof plate 1 is brought into contact with the receiving surface 4 of the metal rafter 2. On the centering groove 7 formed on the top surface of the metal rafter 2, suspenders 8 are placed at intervals in the direction of the eaves. Further, the cap support piece 11 is engaged with the centering groove 13 of the suspender 8 and the cap support piece 11 is placed on the suspender 8. Next, a bolt 23 having a drill portion at its tip is screwed into the metal rafter 2
The suspension 8 and the cap support piece 11 are attached to the fin.

In this case, the elastic receiving piece 5a of the metal roof plate 1 is held by the holding portion 10 of the hanging member 8, and the left and right receiving surfaces 4, 4 of the metal rafter 2 are placed on the receiving surfaces of the metal roof plate 1, 1. The metal rafters 2 and the metal roofing plates 1 and 1 are positioned by bringing the metal rafters 6 and 6 into contact with each other, and the metal roofing plates 1 and 1 are connected to the metal rafters 2. next,
The elastic displacement piece 12a of the cap 12 is elastically contacted with the lower surface side of the elastic receiving piece 5a of the metal roof plate 1, and the lower end of the cap 12 is elastically contacted with the gentle inclined portion 21, and the main part of the cap 12 is supported by the cap. The cap 12 is received by the support portion 18 of the piece 11 and the cap 12 is
It is attached to.

In this manner, the receiving surfaces 6, 6 of the metal roof plates 1, 1 are brought into contact with the left and right receiving surfaces 4, 4 of the metal rafter 2 having a substantially inverted U-shaped cross section, so that the metal rafter 2 and the metal rafter 2 The positioning is performed with respect to the roof slats 1 and 1, and the positioning of the plurality of suspensions 8 arranged at intervals in the ridge eaves direction in the centering groove 7 formed on the top surface of the metal rafter 2. The metal rafters 2 are positioned with respect to the metal shingles 1, 1 and the hangers 8. Therefore, if the metal rafters 2 are installed with linearity in the direction of the eaves, the metal roof plates 1, 1
Can be connected in a straight line,
1 can be easily performed in a linear manner, and the metal roof plate 1 can be firmly attached to the metal rafter 2.

Further, the suspension 8 is fitted into the centering groove 7 of the metal rafter 2 and the cap supporting piece 11 is fitted into the centering groove 13 of the suspension rafter 2. The centering can be performed based on the metal rafters 2. By attaching the cap 12 to the cap support piece 11, it is possible to easily perform the construction in which the cap 12 is straightened in the direction of the eaves.

Also, the elastic receiving piece 5a of the metal roof plate 1 is held by the holding portion 10 of the hanging member 8, and the receiving surface 6 is changed to the receiving surface 4 of the metal rafter 2.
The elastic receiving piece 5a is further pressed against the cap 1.
The elastic displacement piece 12a presses the connection piece 5 by the elastic displacement piece 12a and presses the receiving surface 6 against the receiving surface 4 by pressing the receiving surface 6 of the metal roof plate 1 with the receiving surface of the metal rafter 2 4, the connection strength of the metal shingles 1, 1 is increased. At the same time, the watertightness of the connection point is greatly improved. In this case, a drainage space S is formed between the elastic displacement piece 12a of the cap 12 and the connection piece 5 of the metal roof plate 1, and prevents rainwater from flowing up the connection piece 5 to the connection point. To prevent infiltration of rainwater.

In the present embodiment, a new metal roof plate 1 is laid on an existing roof. That is, a metal rafter 2 having a substantially inverted U-shaped cross section is attached to the roof bar 14 of the existing roof to cover the roof bar 14, and the roof is fixed to the roof base 9 from the existing roof as it is. The metal roof boards 1 and 1 can be connected to the metal rafters 2 and the roof can be easily replaced, and the replacement cost can be reduced.

[Second Embodiment] FIG. 4 is an overall sectional view of a second embodiment. However, the basic configuration of this embodiment is the same as that of the embodiment shown in FIG. 1, and the common parts are denoted by the same reference numerals and description thereof is omitted. In the present embodiment, the cap 12 is formed in an arc shape. In this case, the cap 12 resiliently contacts the holding portions 10 of the suspender 8 while being supported by the support receiving pieces 18 of the cap support piece 11, thereby increasing the support force of the cap 12. The cap support piece 11 is a square cap 1.
