Description

[Detailed description of the invention] [Industrial field of application] The present invention is based on the invention by arranging roofing boards adjacent to each other on the left and right, each of which has an elastic sheet attached to the back side for heat insulation, waterproofing, etc. This invention relates to an improvement in the connection structure of horizontal roofing boards, in which a scrap board is applied to the back side of the end and a decorative cover is applied to the front side.

[Conventional technology]

As this type of connection structure for horizontal roof panels, the one described in Japanese Utility Model Publication No. 3867/1983 is known.
In this conventional structure, as shown in FIG.
The decorative cover attachment part c was fixed to the intermediate part in the width direction of the waste plate a, and the entire left and right side pieces d, d of the decorative cover attachment part c were formed parallel to the waste plate a. Then, as shown in FIGS. 9 and 10,
Groove e formed between waste plate a and left and right side pieces d, d
With the end of the roof plate f... with the elastic sheet h... pasted on the back surface inserted into..., folded piece g... of decorative cover b is inserted between the left and right side pieces d, d and the roof plate f...
It was configured to be inserted from the front between...

[Problem that the invention attempts to solve]

However, in the above structure, when the end of the roof plate f... is inserted into the groove e..., the roof plate f... and the left and right side pieces d, d are brought into close contact by the elastic restoring force of the elastic sheet h... Therefore, it was extremely difficult to fit the folded pieces g of the decorative cover b, resulting in poor workability.

That is, since there is no gap for inserting the folded piece g... between the roof plate f... and the left and right side pieces d, d,
While pushing down the roof plate f... with one hand or the end of the folded piece g of the decorative cover b against the elastic restoring force of the elastic sheet h on the back of the roof plate, the folded piece g of the decorative cover b is pressed down on both the left and right sides d. , d and the roof plate f... from the front requires a troublesome operation, especially when pushing down the roof plate f... with one hand and fitting it from the front of the decorative cover b with the other hand. There was also the risk of injury by hitting one hand on top of the roof panel f with the tip of the decorative cover b. In addition, the elastic sheet h... is formed in such a structure that it is already compressed to some extent when the end of the roof plate f... is inserted into the groove e... between the waste plate a and the left and right side pieces d, d. A considerable amount of pressing force is required to push down the roof plate f, and since the distance i between the top plate of the decorative cover b and the folded piece g is relatively narrow, if the roof plate f is pressed down too strongly, the decorative Even when the tip of the surface plate of the cover b hits the front end of the left and right pieces d, d and the folded piece g cannot be fitted, and the amount of pushing up of the left and right roof plates f does not match, the left and right pieces d, Since the distance between d and the surface of the roof plate f is not parallel, either the surface plate of the decorative cover b or the folded piece g hits one side piece d, making it impossible to fit the folded piece g. . In other words,
In the above conventional structure, the two roof plates f located on both sides of the decorative cover attachment part c are simultaneously moved on both sides against the elastic restoring force of the elastic sheet h attached to their back surfaces. Since it was necessary to move the decorative cover b along the decorative cover attachment part c while pushing down evenly by a predetermined amount, the number of decorative covers used per building usually ranged from tens to hundreds. Because of this, the installation work is very troublesome and requires great skill.

In view of the above-mentioned conventional drawbacks, the present invention provides a horizontal roof board connection structure with good workability in which the elastic restoring force of the elastic sheet does not interfere with the work of attaching the decorative cover.

[Means for solving problems]

In order to achieve the above object, the present invention provides the connection structure for the horizontal roof boards mentioned at the beginning, in which the front end bending the portion upward to form a guide piece, forming folded pieces on the left and right edges of the decorative cover, and placing the folded pieces of the decorative cover between the left and right sides of the decorative cover mounting portion and the roof board. The decorative cover is fitted into the decorative cover mounting portion.

The structure is such that a gap larger than the plate thickness is formed.

At least one side piece 14 (upper plate part of the first metal fitting C ₁ ) is provided with an appropriate distance outward from the bottom surface of the groove 12 (for example, 5 mm in consideration of thermal expansion of the roof plate 1).
It is set to a certain degree. ) A plurality of stopper pieces 15 at distant positions for limiting the insertion depth of the roof sheet 1 and forming a gap S ₁ inward from the edge of the roof sheet 1 to absorb thermal expansion of the roof sheet 1. It is formed by cutting and raising the ... downward. These stopper pieces 1
5... is configured to be pressed and deformed by the edge of the roof sheet 1 when the roof sheet 1 expands in the lateral direction.

In the figure, 16 is a sealing rubber gasket attached to the positioning protrusion 8, and 17 is a roof base such as rafters and roofing boards.

The connection structure of the above-mentioned horizontal roof panels will be explained in the order of construction as follows.

First, among the left and right adjacent roof panels 1..., the end of one of the roof panels 1 is inserted into the groove 12 of the first metal fitting C ₁ fixed to the scrap board A. Place the roof board 1 on the roof base 17 with the roof board 1 inserted to the position where it hits ..., and connect the engaging part 2 to the locking part 3 of the previously covered roof board 1.
After hanging it, fix it to the roof base 17 using a hanger (not shown).

Next, with the second metal fitting C ₂ fitted to the end of the other roof sheet 1 on the side to be connected until the bottom of its groove 13 hits the edge of the roof sheet 1, the roof sheet 1 is attached to the Place it on the top surface of plate A. in this case,
The second metal fitting C ₂ is placed with a gap S ₂ of an appropriate distance (for example, about 5 mm) formed between the second metal fitting C _{1 and the first metal fitting C 1} . This is to absorb the thermal expansion of the roof board ₁ fitted with the second fitting C2.

In this state, the engaging portion 2 of the roof sheet 1 is hooked onto the locking portion 3 of the previously covered roof sheet 1 located below the slope, and attached to the roof base 17 via the hanger. Fix it.

After that, the folded pieces 9 at both ends of the decorative cover B are attached to the left and right side pieces 14 of the decorative cover mounting portion C formed by the first metal fitting C ₁ and the second metal fitting C ₂ and the roof plate 1.
...Insert the downward bent portion 10 and the upward bent portion 11 between the left and right roof panels 1 from the front, respectively.
externally and internally fitted into the engaging part 2 and the locking part 3,
The connection of the roof panels 1 at this part is completed. In this case, the guide pieces 14a of the left and right pieces 14 are bent upward in advance, and the folded pieces 9 are placed between the roof panels 1 and the guide pieces 14a.
Since the structure is configured to form a gap larger than the plate thickness of the decorative cover B, even if the roof plate 1 is pushed up into a state in close contact with the side pieces 14 due to the elastic restoring force of the elastic sheet 4, the decorative cover B The tips of the folded pieces 9 can be inserted under the guide pieces 14a.
Then, the tips of the folded pieces 9 are connected to the guide pieces 14a.
...All you have to do is insert it under the cover B.
It can be easily fitted by pushing it backwards. Furthermore, when the decorative cover B is fitted, the guide pieces 14a come into pressure contact with the back surface of the decorative cover B due to their elastic restoring force, so that wobbling of the decorative cover B is effectively prevented.

Thereafter, by repeating similar operations, the roof sheets 1 are laterally installed one after another.

In this case, the first metal fitting C ₁ fixed to the waste board A will be fitted to the end of the roof board 1 which is fixed to the roof base 17 from now on, but the dimensions of the waste board A are Since it is small and lightweight, this fitting operation is relatively easy.

In particular, since the second metal fitting C ₂ is simply fitted onto the end of the next roof plate 1 and placed on top of the fixed scrap plate A, it is not necessary to use the conventional method. This is much easier than lifting a long roof board and inserting the end of the roof board into a narrow gap in an already fixed shingle.

Therefore, the construction can be carried out easily, safely and quickly by one person without the need for a skilled person.

FIG. 7 shows another embodiment of the invention. In this embodiment, in a structure similar to the conventional structure shown in FIGS. 9 and 10, the front end portions of the left and right side pieces 14 of the decorative cover mounting portion C fixed to the waste plate A are used to extend the entire width in the left and right direction. A folded piece 9 of the decorative cover B is formed between the guide piece 14a and the roof plate 1 which is bent upward over the entire length and inserted into the grooves 12 and 13. It is distinctive in that it is constructed to form a void. In addition, the standing piece 7 for draining at the rear end of the waste board A is the locking part 3 of the left and right roof boards 1...
..., and the rear edges of the decorative cover B are configured to fit inside the locking portions 3 of the left and right roof panels 1.

FIG. 8 shows another embodiment of the present invention, in which the left and right side pieces 14 of the decorative cover mounting portion C...
It is characterized in that a protrusion protruding forward is provided at the front end of the guide plate 14a, and the protrusion is bent upward to form the guide pieces 14a. In the drawing, the decorative cover attachment part C is fixed to the waste plate A as in the embodiment shown in Fig. 7, but as in the embodiment shown in Figs.
It may be constructed of a first metal fitting _C1 fixed to the scrap plate A and a second metal fitting _C2 not fixed to the waste plate A.

[Effect of idea]

The present invention has the above-mentioned structure, and the front ends of the left and right sides of the decorative cover attachment part are bent upward to form guide pieces, so that the left and right sides and the roof plate are connected to the back side of the roof plate. Even if they are in close contact due to the elastic restoring force of the elastic sheet attached to the roof, there is a gap at the position of the guide piece, so even if the roof board is not pushed down against the elastic restoring force of the elastic sheet, The tip of the folded piece can be easily inserted below the guide piece. All you have to do is insert the tip of the folded piece under the guide piece and then push the decorative cover backwards.
Since it can be easily fitted, workability is improved.

In particular, as in the first embodiment, the decorative cover mounting portion is provided with a first metal fitting having a substantially U-shaped cross section and having a groove into which an end of one roof plate is fitted, and which is fixed to the waste plate; If it is composed of a second metal fitting which has a substantially U-shaped cross section and has a groove into which the end of the other roof plate fits, and which is not fixed to the waste plate, as in the conventional case,
This eliminates the troublesome work of lifting a roof board and inserting its end into the already fixed waste board, further improving workability.
