[Technical field to which the device belongs]

 The present invention relates to a corrugated iron plate roof material for roof plates. More specifically, the roof plate installation structure is effective for preventing the roof plate from being distorted due to the vertical expansion and contraction of the roof plate and rupturing the fastening holes. It is about.

[0002]

[Prior art]

 Generally, when installing a corrugated roof plate made of iron, a tight frame is installed on the C-shaped beam, and a roof plate support part bent into a C-shape is arranged on this tight frame in the direction of the C-shaped beam. Place the connection edge of the roof plate on the roof plate support part, put the front connection edge of the post-construction roof plate on the rear connection edge of this roof plate, and fix the connection edge of each roof plate and the roof plate support part with bolts or screws. Doing is the usual method of constructing iron roof plates. Here, in order to prevent rainwater from entering the fastening holes, it is sealed with waterproof liquid, waterproof paint, shilling material and the like.

[0003]

[Problems to be solved by the device]

 However, after such a conventional iron corrugated roof plate is installed, there is an expansion and contraction action that expands or contracts in the vertical direction under the influence of changes in atmospheric temperature. Stretching in the width direction has no side effect if it is dealt with by expanding or shrinking wrinkles, but there was no way to deal with stretching in the vertical direction. Furthermore, since the tight frame and the roof plate support are fixed by installation, when the roof plate is expanded and contracted in the vertical direction, it was not possible to cope with the change. Side effects such as distortion of the roof panel of

Most of the connecting edges of the iron roof plate are bent in the corners of a trapezoid, and the top surface of the bent wrinkle is flat, and the connecting edge cuts the top surface of the wrinkle. Although it is formed by the method described above, it is slightly flat, but it is not a flat state in a strict sense, but is likely to be a partially distorted non-linear flat surface.

When the connecting edges of the roof plates thus deformed to have an incomplete flat surface are vertically overlapped and connected to each other, a space is not formed completely in some places like two plates of glass are overlapped with each other. Will slip. When a space is created at the connecting edge of the roof panel, water leakage may cause rust on the inner surface of the roof panel, which may cause fatal problems in durability.

Therefore, the object of the present invention is to install the corrugated roof plate so that the fixing screw hole does not burst even if the iron corrugated roof plate expands or contracts in the vertical direction due to temperature changes and the plate surface is not distorted. It is to provide a roof plate installation structure to obtain.

Another object of the present invention is to provide a roof plate installation structure that can easily, quickly and completely prevent water leakage at a roof plate connection portion without using a sealing material such as waterproof paint.

[0008]

[Means for Solving the Problems]

 The present invention comprises a roof plate fixing member including a supporting part, a guiding part and a roof plate supporting part, and a roof plate connecting edge protecting member including a connecting edge protection cap and a cap support. The roof plate support is configured to be loosely inserted into the support guide. Roof plate Since the support part is fixed to the roof plate with bolts or screws, when the roof plate expands and contracts in the vertical direction due to changes in atmospheric temperature, the roof plate expands and contracts because it moves on the support guide by the amount of expansion and contraction. Is free. Therefore, even if the roof plate expands and contracts, bolts or screws are inserted by moving the roof plate support part, which fixes the roof plate, in the expansion / contraction direction on the support guide, that is, in the vertical direction of the roof plate. The screw holes on the roof plate connection edge do not burst or distort.

In addition, according to the present invention, the cap fixing tool is placed on the exposed connection edge of the roof plate and then fixed together with the roof plate by bolts or screws, and the cap fixing tool is covered with the connection edge protection cap and engaged. Let When the connection edge protection cap is put on the connection edge of the roof plate, both the screw hole and the bolt or screw are blocked and are not exposed. This eliminates the need to take any additional sealing measures even if the connecting edges of the roof plates are not in close contact with each other, and the contact between the bolt or screw and water is eliminated, so that there is no concern about corrosion.

[0010]

[Embodiment of device]

 Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings prepared based on the preferred embodiments.

The support guide 1 is bent upward on both sides in the width direction to erect the upright locking steps 11, and the upper ends of the upright locking steps 11 are bent inward to horizontally lock the parts 12. And Here, the main roles of the upright locking step 11 and the horizontal locking portion 12 with respect to the roof plate supporting portion 2 are to prevent the roof plate supporting portion 2 from separating upward and to guide the movement in the vertical direction. . In order to more reliably perform this role, the space (S) formed by the upright locking step 11 and the horizontal locking portion 12 has a sufficient upward rib 22 formed at the wing end of the roof plate supporting portion 2. It is formed into a size that can be received by

The width of the horizontal locking portion 12 is such that the upward rib 22 is horizontally locked even when the roof plate supporting portion 2 inserted in the supporting portion guide 1 is biased to one side in the width direction. It is appropriate that the portion 12 cannot be detached upward by hanging on the portion 12. As a method of increasing the bending strength of the horizontal locking portion 12, it is possible to fold the free end portion of the horizontal locking portion 12 upward or downward to form the bending rib 13. In the drawings of this embodiment, the sheet is bent downward.

The support part guide 1 may be any of an injection molded product, an extruded product, and a bent part of an iron plate. However, in the case of an injection molded product, it is desirable to use a synthetic resin that is thick and has sufficient strength, and has heat resistance and cold resistance.

In the roof plate supporting portion 2, the ends of both side wings 21 that are inserted into the supporting portion guide 1 which is the base portion are bent upward in parallel with the vertical wall of the roof plate 2. The facing rib 22 is formed. Since the wing portion 21 and the upward rib 22 should be loosely inserted into the support portion guide tool 1, the bottom width including both wing portions 21 should be formed slightly smaller than the inner surface width of the support portion guide tool 1. The upward rib 22 is also formed to be slightly smaller than the upright locking step 11 of the support guide 1, so that it does not become too loose when it is inserted into the support guide 1, and a stable posture is maintained as much as possible. To do so.

Since the supporting part guide 1 and the roof plate supporting part 2 need only have such a length as to include a sufficient screw hole in the longitudinal direction thereof, the supporting part guide 1 and the roofing plate supporting part 2 may be manufactured in advance or shortened in advance. Cut and use.

The connecting edge protection cap 3 is formed by bending both side edges downward to form a bent portion 31, and forming inward steps 32 parallel to the length direction at the ends of the both bent portions 31. It is formed . The bent portion 31 covers the lengthwise edge portion of the cap support 4, and the inward step 32 enters below the both-side bent portions 41 of the cap support 4 and engages with the both-side bent portions 41 for connection. The edge protection cap 3 becomes stable. In order to prevent the substrate surface 33 of the connection edge protection cap 3 from being distorted, it is required to treat it as an arcuate surface as shown in the drawing rather than a flat surface.

The cap support 4 is fixed on the connection edge of the roof plate to support the connection edge protection cap 3, and folds for engaging and fixing the inward step 32 on both sides in the length direction. A bent portion 41 is formed, and a fastening hole 42 into which a bolt or a screw for fixing the roof plate is inserted is formed at the center of the plate surface.

Since the connection protection cap 3 should cover the entire connection edge of the roof plate so as to completely surround it, the connection protection cap 3 is formed to have a length equal to that of the roof plate and a size enough to completely cover the connection edge. . However, even if the cap support 4 is sparsely arranged on the connection edge of the roof plate, it is reasonably possible to stably support the connection edge protection cap 3, so it should be formed in advance shortly or used long. Can be cut and used.

FIG. 2 shows a state in which the corrugated roof plates 5a and 5b are constructed by using the support guide 1, the roof plate support 2, the connection edge protection cap 3 and the cap support 4.

As shown in the figure, a bolt 7 is fixed on a well-known tight frame 6 which is previously fixed on the C-shaped beam, and a fastening hole 14 of the support guide 1 is inserted into the upper end of the lead of the bolt 7. To do. Next, the upright locking steps 11 are placed upright so that they are aligned with the C-shaped beam, and the nut 8 is fastened from above to fix the support guide 1. The wing portion 21 of the roof plate supporting portion 2 is inserted into the supporting portion guiding tool 1. In this way, the roof plate support portion 2 becomes movable on the support portion guide tool 1 in the longitudinal direction of the support portion guide tool.

The front connection edge 51 of the pre-installed roof board 5a and the rear connection edge 52 of the post-installed roof board 5b are combined with the fastening holes 23 of the roof board support section 2 to form fastening holes, and the roof board support section is formed. The front connection edge 51 of the pre-constructed roof plate 5a is placed on 2. Then, the rear connection edge 52 of the post-construction roof plate 5b is placed on the front connection edge 51, the fastening holes of each connection edge are aligned with the fastening holes 23 of the roof plate support portion 2, and then the rear connection edge 52 is folded. The cap support 4 of the end piece is placed so that the end of the bent portion 41 faces downward, the fastening hole 42 is aligned with the fastening hole 23, and the bolt 9 is fastened 1 to connect the front connecting edge 51 and the rear connecting edge 52. Together with this, it is fixed to the roof plate support portion 2.

After the roof plates 5a and 5b and the cap support tool 4 are installed in this order, the cap support tool 4 is covered with the connection edge protection cap 3, and the inward step 32 is locked to the lower end of the bent section 41. By doing so, the construction of the connection edge protection cap 3 is completed.

The roof plate installed in this way expands and contracts vertically and horizontally depending on the seasonal temperature change. Especially, when the roof plate expands and contracts vertically, the roof plate support part 2 is pulled by the roof plate to guide the support part. It moves on the tool 1 in the length direction of the roof plate, that is, in the direction of the C-beam, and the bolt 9 follows it. At this time, the cap support tool 4 also slides in the connection edge protection cap 3 together with the roof plate. Since the roof plate 2 and the bolt 9 move in the vertical direction together with the roof plate in this manner, the screw holes of the roof plate do not burst and the connection edge is not distorted. Further, when the connection edge protection cap 3 expands or contracts, it slides by the cap support 4, so that the connection edge protection cap 3 also maintains the normal state in spite of the temperature change.

FIG. 3 shows a modification of the present invention. In the previous embodiment, the support guide 1 of the supporting portion 1 is directly contacted with the tight frame 6 and fastened with a short bolt 7, and the roof plate supporting portion 2 is raised. On the other hand, in the present embodiment, the roof plate support portion 2 is made low, and instead, the height of the shortage is replaced by the long bolt 7-1 for connecting and fixing the support portion guide 1 and the tight frame 6 to each other. Is.

[0025]

[Effect of device]

 As described above, according to the roof plate installation structure of the present invention, when the iron corrugated roof plate is vertically expanded and contracted due to temperature changes, the roof plate support moves vertically on the support guide. Therefore, the corrugated shingles can be installed so that the shingles for fixing the shingles do not burst, the connecting edges of the shingles are not distorted, and they are completely maintained.

Further, according to the present invention, the cap support installed on the connecting edge of the roof plate is simply covered with the connecting edge protection cap, so that the roof plate connecting portion can be easily, quickly and completely installed without a sealing material such as waterproof paint. Water leakage prevention work can be completed, and the cap support is exposed when the connection edge protection cap is removed upward, so maintenance and repair of the roof plate, connection edge protection cap, cap support, etc. is also very easy. Is.
