Description

[Detailed description of the invention] This invention relates to a roof draining device for prefabricated buildings, and involves joining a ridge roof plate that covers the ridge of the roof and eaves root plates that are connected to the lower parts of the left and right outer sides of the ridge roof plate. The purpose of this is to improve the drainage effect at the ridge and increase the strength of the joint between the ridge and the eaves.

An embodiment of the present invention will be explained with reference to the drawings.
Fig. 1 is a perspective view showing the entire structure of an assembled garage using the draining device of the present invention, with the left side roof panel omitted, and Figs. 2 and 3 illustrate the structure of its main parts. In the figure, reference numeral 1 is a corrugated roof plate for the eaves, 2 is a flat roof plate for the ridge, which is a transparent or opaque elastic plate curved in a semicircular shape, and 3 is a semicircular ridge. Frame, 4 is a roof beam, 5 is a grooved purlin installed on the inside near the ridge, 5' is a grooved purlin installed in the middle, 6 is a draining board, 7 is a ridge sill, 8 is a support sill, 9 is a girder Board 10 is a hidden end and rain gutter.

The roof structure in this embodiment is such that a semicircular ridge frame 3 is erected on the center top of each horizontally elongated trapezoidal roof beam 4 with the center top as the horizontal side. Groove-shaped purlins 5 on the inner side of the main building are constructed in the front-rear direction along the outer sides of both bases of the multiple ridge frames 3 installed in parallel, perpendicular to the roof beams 4, and parallel roofs are also installed between the groove-shaped purlins on both sides. A ridge frame of the same shape as the ridge frame 3 is erected between the beams, and an intermediate groove-shaped purlin 5' of the same shape is also erected in parallel to the outer middle part of the inner groove-shaped purlin 5, and each of the ridge frames The apexes are connected by a ridge 7, and the ridge frame group arranged in parallel is constructed by raising the ridge root in a semicircular shape from the eaves roots on both sides, and this semicircular raised ridge The roof is covered with flat roof plates 2 that are curved in a semicircle along the ridge frame 3, and on both sides of the ridge and at the eaves, inner groove-shaped matrices are placed on the downward slopes of the roof beams 4 on both sides. A house 5 has a corrugated roof board 1 installed through an intermediate channel-shaped main house 5', and the corrugated roof board 1 has a wide flat valley part 1a and a narrow peak part 1 on its surface.
b are alternately curved, and the crossbars 1c are attached in the horizontal direction at both upper and lower ends and the middle part of the back surface, perpendicular to the valleys and peaks, and upward along the upper edge of the valley. A folded upper piece 1d is formed, and the upper end crosspiece 1c and the intermediate crosspiece 1c are fitted into the respective grooves of the inner groove-shaped main house 5 and the intermediate groove-shaped main house 5'. By screwing on the upper part, the roof can be placed on both the main houses, and the upper folded piece 1d can be attached to the inner wall 5 of the inner groove-shaped main house 5.
It is arranged along the inside of the water section 5b extending diagonally upward along the ridge base from a.

Then, a draining plate 6 is placed and covered on the upper edge of the corrugated roof board 1, and the lower end of the draining plate 6 is bent diagonally downward, and a hanging piece 6a is formed with a large number of cut holes 6b. are arranged in rows, and the notch holes 6b of the hanging pieces are engaged with the peaks 1b of the roof board 1, and
Insert the comb tooth-shaped fragment part formed between each cut hole into the valley part 1a of the roof board, and connect the upper end part to the upper part of the water section 5b of the inner channel-shaped purlin 5 to the lower end of the raised ridge part. A locking piece 6d is attached to the draining plate in a parallel manner on the outer side of the upper surface of the rising piece 6c. is fixed by screwing onto the base of the ridge frame 3.

In addition, a transparent or opaque flat roof board 2 is pasted on each of the ridge frames erected in parallel in a semicircular manner along the top surface of the ridge frame, and the lower edges on both sides are attached to the upright side of the draining board 6. After inserting and locking into the gap between the piece 6c and the locking piece 6d, the roof board is pressed and screwed from the top surface of the same roof board toward the ridge frame 3 with a presser 8, thus covering the raised ridge part. This ridge roof plate 2 is divided into a plurality of front and rear pieces on each ridge frame and arranged in parallel, and the joints are connected by a presser 8.

In addition, at the eave end of the eaves root, the groove of the groove-shaped support 9a of the roof support part is formed to extend along the upper edge of the girder plate 9 screwed to the side end of each roof beam. A horizontal beam 1c at the lower end of the roof board 1 is inserted into the roof board 1, and a cover and rain gutter 10 is placed on the side end of the roof board.

In addition, the roof board 1 is fixed on the back side by sewing and screwing the upper and lower horizontal beams fitted into the grooves of the groove-shaped purlin or groove-shaped support in the horizontal direction together with the purlin or the support in a vault. However, its illustration is omitted.

Since the present invention has the above-described configuration, it has the following effects.

After fitting and screwing the crosspiece 1c on the back side of the upper end of the corrugated roof board 1 into the groove of the groove-shaped purlin 5 on the outside of the ridge, the folded-up piece 1d at the upper end of the roof plate is attached to the water section 5 on the side of the groove-shaped main house.
b, and a draining plate 6 is placed on the upper edge of the roof plate.
The cut holes arranged in the hanging piece at the lower end of the draining plate 6 are engaged with the peaks of the roof plate, and the pieces are inserted into the valleys of the roof plate, The upright piece 6c is arranged along the ridge base, and the ridge root board 2 is placed in the gap between the locking piece 6d attached on the upright piece and the upright piece.
Since the lower edge of the groove-shaped purlin 5 is inserted and locked,
The water interceptor 5b, the folding piece 1d at the upper end of the corrugated roof plate, the rising piece 6c at the upper end of the water-cutting plate 6, and the hanging piece 6a at the lower end can block moisture at the joints at each end, so that the connection between the ridge roof and the eave roof is The drainage effect at the joint part is good, and the folded piece 1d at the upper end of the valley of the eave root can block water blowing up from the outside and prevent water from leaking into the interior. Since various members such as the grooved purlin 5, the horizontal beam 1c on the back of the corrugated roof board, the folding piece 1d, and the draining board 6 are connected together, the roof joint is strong and can withstand strong wind pressure. A strong raised ridge roof can be constructed.
