Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention has an extremely simple structure, can be constructed in a watertight manner, can be constructed easily and inexpensively, and can be used to install horizontal roofing sheets at the lower part of the ridge. This invention relates to a ridge repair structure for horizontal roofs that can cope well with thermal expansion and contraction in the longitudinal direction.

[Conventional technology and its problems]

Conventionally, when repairing the ridge part of a horizontal roof, a ridge wrapping material or the like is attached, but the structure is generally complicated and the construction is troublesome. In addition, there were drawbacks such as spoiling the aesthetic appearance. Additionally, there were drawbacks such as strong wind and rain at the point where the ridge was dropped off, and poor watertightness. In addition, there was also the drawback that the roof panels could not cope well with thermal expansion and contraction in the longitudinal direction of the horizontal roof panels at the point where the ridge fell.

[Means to solve the problem]

Therefore, the inventor worked diligently to solve the above problem.
As a result of repeated research, the present invention has been applied to the lower ridge of a horizontal roof, which is constructed by engaging the inner engaging part and the outer engaging part of the horizontal roof plate. Cut the ends of the roof panels to form an appropriate distance that is approximately parallel to each other, and fold the locking pieces upward from the opposite ends of the main panels. While inserting and locking the locking edges on both sides of the landing ridge joint plate with the locking edges folded downward at least in part into the locking pieces on the left and right sides of the space, the landing ridge joint plate is used near the space. By configuring the locking points to allow expansion and contraction of the horizontal roof panels, watertight construction is possible with an extremely simple configuration, and construction is simple and inexpensive. The above-mentioned problem can be solved by being able to cope well with thermal expansion and contraction in the longitudinal direction of the horizontal roof board at the point where the ridge is to be lowered.

This is placed on the structural member 1 so as to face the slope direction of the roof (including cases where it is slightly shifted from the slope direction), and the supporting members 2 are placed at appropriate intervals (approximately 30 cm to approximately 1 cm).
A large number of them are attached, except m). A base plate 3 such as a board or a heat insulating plate is laid between the supporting members 2, 2. A double supporting member 2 is provided at the lowering point of the roof. A base board 3, such as a heat insulating board, is also laid between the support material 2 at the ridge drop point and the support material 2 in the general part. As shown in FIG. 2, the cross-section of the ridge descending area is configured to slope downward on both sides with the double support members 2 and 2 as boundaries. The double supporting members 2, 2 may be integrally formed using separate members.

A is a metal roofing board for horizontal roofing, which has an appropriate length or length in the longitudinal direction, and this roofing board A for horizontal roofing has an appropriate length or length in the longitudinal direction.
When viewed as a cross section perpendicular to the longitudinal direction, the engaging portion 5 is formed on the inner side upward from one side (above the water side) of the main plate 4, and the engaging portion 5 is formed on the inner side downward from the other side (underwater side) of the main plate 4. An outer engaging portion 6 facing towards is integrally formed. This outer engaging portion 6 is configured to appropriately engage with the inner engaging portion 5 of the horizontal roofing plate A at the lower end. The main plate 4 is bent from one side to a flat part, a gently sloped part, and a flat part, and the horizontal roofing plate A, which is composed of the main plate 4, an inner engaging part 5, an outer engaging part 6, is a single metal plate. are bent as appropriate and integrally formed. A heat insulating material such as foamed synthetic resin is adhered to the lower surface of the horizontal roofing board A as required. Reference numeral 7 denotes a hanger, and a mounting portion 7b is integrally formed outward from the lower end of a locking portion 7a having a mountain shape or the like.

The horizontal roofing board A is placed on the support material 2 so that its longitudinal direction is perpendicular (including substantially perpendicular) to the longitudinal direction of the supporting material 2, and the inside of the horizontal roofing board A is The engaging portion 5 is a locking portion 7a such as a mountain shape of the hanger 7.
At the same time, the attachment part 7b of the hanger 7 is fixed to the supporting material 2 with fixing tools such as rivets and drill screws, and then the outside of the horizontal roofing board A on the upper side (water side) of this step is fixed. The engaging part 6 is engaged with the inner engaging part 5 of the horizontal roofing board A of the lower tier, and this is successively repeated on the water side to form the roof. At the point of descent from the ridge, this is formed symmetrically, as shown in FIGS. 1 and 2. At this time, the ends of the opposing horizontal roofing plates A and A at this ridge landing point are cut at an appropriate angle θ (for example, an angle of about 30 degrees to about 60 degrees) when viewed from above (Fig. 1, (Refer to FIG. 5), thereby, the opposing cutting portions of the ridge drop portion are formed at appropriate intervals so as to be substantially parallel when viewed in plan.

Then, the locking pieces 4a, 4a are folded upward from the ends of the main plates 4, 4 of the opposing horizontal roof panels A, A, respectively.

Reference numeral B designates a joint plate for getting off the ridge, in which locking edges 8a, 8a are folded downward from both sides of the main joint plate 8 in the width direction, at least in a part of the longitudinal direction of the sides, and the main plate 8 of the joint A bent portion 9 that engages with the outer engaging portion 6 is provided at the front end, and a rising piece 10 is provided at the rear end of the joint main plate 8. The length of the joint main plate 8 in the front-rear direction and the shape seen from the side of the main plate 8 are as follows:
It is approximately the same as the other parts, and is formed symmetrically. In reality, the joint plate B for descending ridge has a shape that is slightly curved compared to the bent state of the main plate A of the roof plate A for horizontal roofing, and when placed on the roof plate A for horizontal roofing, It is often formed to be more closely attached due to the springback phenomenon within the elastic limit.
Specifically, as shown in FIG. 3, from both sides of the joint main plate 8 in the width direction, relatively wide locking edges 8a, 8a are formed downwardly by folding over the entire longitudinal direction of these sides. Alternatively, as shown in FIG. 4, wide locking edges 8a, 8a are folded downward from both sides of the joint main plate 8 in the longitudinal direction of the sides, and A relatively narrow folded edge 8b is formed on the lower side between the locking edges 8a, 8a.

As shown in FIGS. 1 and 2, the mounting structure of the connecting point of the connecting plate B for the connecting plate B is as shown in FIGS. 1 and 2. It is inserted and locked into the locking pieces 4a, 4a of the opposing main plates 4, 4 of the horizontal roof plates A, A, and at the same time, the joint main plate 8 of the joint plate B for the roof roof is inserted and locked.
The space between the adjacent horizontal roof panels A and A and the locking pieces 4a and 4a on the left and right sides are covered, and the locking points are designed to prevent expansion and contraction of the horizontal roof panels A. configured to be acceptable. That is,
A space is secured in which the horizontal roofing board A can be thermally expanded and contracted in the longitudinal direction. Then, the bent portion 9 at the front end of the joint plate B for descending ridge is engaged with the outer engaging portions 6, 6 of the adjacent horizontal roof plates A, A, and further,

〔Effect of the invention〕

In the present invention, in a descending ridge of a horizontal roof that is constructed by engaging the inner engaging portion 5 and the outer engaging portion 6 of the horizontal roofing plate A, the horizontal roof plate The roofs A and A ends are cut to form a substantially parallel appropriate interval, and the main plates 4, 4 facing each other are
A joint for getting off the roof in which the locking pieces 4a, 4a are each folded upward from the end, and the locking edges 8a, 8a are folded downward from both sides of the joint main plate 8 in the longitudinal direction at least in part of the longitudinal direction of these sides. Locking edges 8a, 8 on both sides of plate B
A is inserted and locked into the locking pieces 4a, 4a on the left and right sides of the above-mentioned interval part, and the vicinity of the interval part is covered with the joint plate B for getting off the ridge, and the locking part is attached to the horizontal roof board A. By configuring the structure to allow expansion and contraction, firstly, the connection point can be constructed watertight with an extremely simple structure, secondly, the connection point can be installed easily and quickly, and thirdly, the connection point can be installed easily and quickly. It can cope well with thermal expansion and contraction in the longitudinal direction of the architectural board A for horizontal roofing, and has the fourth effect of being strong and having a good architectural appearance.

To explain these in detail, first, while inserting and locking the locking edges 8a, 8a on both sides of the joint plate B for getting off the ridge into the locking pieces 4a, 4a on the left and right sides of the above-mentioned interval, the joint plate for getting off the ridge. B covers the vicinity of the gap, and the locking point is configured to allow expansion and contraction of the horizontal roof board A, and the connecting point of the ridge was cut in cross section (see Figure 2). A hollow part is formed in the side part by the side part in the width direction of the main joint plate 8 of the joint plate B for getting off, the locking edge 8a, the end of the main plate 4, and the locking piece 4a, and the tip of the locking edge 8a Even if rainwater enters from the side, it is blocked by the locking piece 4a, and furthermore, the existence of the hollow part prevents the rainwater from capillary phenomenon and allows the rainwater to flow down to the bottom side.
It is possible to provide a ridge repair structure for horizontal roofs with extremely excellent watertightness (rain closure). Even with such a configuration, the configuration is simple and the construction is simple and quick since the connecting plate B for the egress ridge is simply locked to the locking piece 4a of the main plate 4. There are some advantages to doing so.

Furthermore, at the connection part of the lower ridge, by covering the main plates 4 and 4 ends of the horizontal roofing panels A and A, the horizontal roofing panels A are made of a highly elastic material (copper, etc.). Even if the temperature difference in the area where the horizontal roofing board A is installed is large, the horizontal roofing board A will be able to maintain the thermal expansion and contraction that occurs in response to the outside temperature in the longitudinal direction at the above-mentioned intervals. can be absorbed and
In particular, the joint main plate 8 of the joint plate B for the lower ridge is not fixed to the end of the horizontal roofing plate A on either side of the gap, and is free, so that No thermal stress is generated on the horizontal roof panels A, A, and even the entire horizontal roof, and in particular, almost no deformation strain occurs in the main plate 4 of the horizontal roof panels A exposed on the outer surface. This makes it possible to create a strong connection structure in which almost no deformation strain occurs even when subjected to external forces such as earthquakes, and it is possible to prevent the conventional reduction in strength due to strain generation and the plate rattling phenomenon.

Also, the locking edges 8a, 8 on both sides of the joint plate B for getting off the ridge
By inserting and locking a into the locking pieces 4a, 4a on the left and right sides of the space, the joint plate B for getting off the roof can be made strong without coming off even in strong winds and rain. In particular, if it is constructed using the joint plate B for getting off as shown in Fig. 4, and only a part of it is locked, insertion and locking can be done extremely efficiently, and as shown in Fig. 3, When the locking edge 8a is provided over the entire length of the ridge joint plate B, this locking edge 8a and the locking piece 4a
The whole part is locked, making it extremely difficult to dislodge, making it extremely strong. By constructing the roof in this way, the ridge of the horizontal roof has a continuous step pattern similar to that of the general area, and the architectural beauty can be improved.
