Description

[Detailed Description of the Invention] This invention relates to a roof structure in which extruded aluminum is used as the main member in the bay window.

Since bay windows are generally quite long and protrude, it is not possible to construct a roof board with a single sheet of aluminum extruded section due to the technical limitations on the forming width, and with a standard bay window, the roof board is made up of two sections. Must be configured. However, when two sections are assembled together, rainwater will inevitably enter through the joints due to capillary action unless the sections are carefully filled with caulk. Furthermore, even if a caulking material is used, its effectiveness will eventually diminish due to peeling and cracking due to vibration, shrinkage due to drying, etc.

From the above point of view, the purpose of this invention is to make it possible to drain the rainwater to the outside without any problem, assuming that rainwater enters through the joint between two sections.

Next, an embodiment of this invention will be described based on the drawings.

First, I will explain the general structure of bay window A.
The mounting members 3, 3 of the bay window A are fixed to the outer surfaces of the columns 2, 2 on both sides of the house opening 1, the bay window front frame 5 into which the shoji 4 fits is provided at the front end, and the vertical frame 6 of the bay window front frame 5 and the mounting members Upper and lower arms 7 and 8 are sandwiched between the bolts 9 and nuts 10 inserted through the arms 7 and 8.
The arms 7 and 8 are fastened together, and a roof R is formed at the upper end, and a base plate 11 is fitted at the lower end, 12 is a joist, and 13 is a bottom cover.

The roof R has an overall structure including a mounting member 3, two front and rear roof plate members 14, 15, a bay window upper frame 16,
It is assembled by a ceiling board 17, a ceiling board hanger 18, a plurality of brackets 19, an upper arm 7, and a side board 20, among which the ceiling board 17, the brackets 19,
Extruded aluminum members are used for members other than the side plates 20.

The bay window front frame 5 is assembled by sandwiching an upper frame 16 and a lower frame 22 between the left and right vertical frames 21, 21, and screwing screws into the screw pockets 23 from the vertical frames 21, 21. The upper frame 16 is a horizontal upper wall 2.
Inner and outer walls 25 and 26 and engaging rails 27 and 28 for the inner and outer shoji 4 are vertically provided on the inner and outer walls 25 and 4, and a hook-shaped hook 29 with a forward tip is protruded from the rear end. A ceiling hanging groove 30 is provided at the lower end, and a drain hole 31 that opens between the outer shoji engagement rail 28 and the outer wall 26 is provided in the upper wall 24, and both ends 32 of the upper wall 24 are vertically It abuts against the upper end surface 33 of the frame 6 so that the upper surface is uniform. The vertical frame 6 has a main body 34 formed into a cylindrical shape with a square cross section, and has a hollow portion 35 that extends upwardly and downwardly.

Next, the rear roof plate member 15 of the roof R has an attachment piece 36 to the house H erected at the rear end, and a connecting piece 37 that extends to and hooks onto the upper frame 16 on the lower surface near the front end. Attachment pieces 38 and 39 of the bracket 19 are vertically provided at the rear end and the middle part. Further, a protrusion 40 is vertically provided near the tip of the connecting piece 37, and the connecting piece 37 has a lower part inclined forward lower than the proximal end, and a higher forward slope near the inclined upper end. Piece 4
1 is provided in a protruding manner, a hooking portion 42 is formed diagonally downward at the upper end of the inclined piece 41, and an engaging piece 43 for engaging with the hooking piece 29 of the upper frame 16 is provided at the lower end.

The front roof board member 14 is provided with a gutter-shaped hooking part 44 that passes under the rear roof board member 15 and hooks with the protrusion 40 at the rear end, and a sloped piece 41 is provided near the rear end.
An overlapping piece 45 is provided protrudingly to be joined to the lower surface of the overlapping piece 4.
5 is formed with an engaging groove 46 that is hooked onto the hook portion 42 of the inclined piece 41. Also, this front room root board member 1
A reversing piece 47 that bends downward is provided at the front end of the reversing piece 4, and the tip of the reversing piece 47 is hung on the front end of the upper frame 16 to bring it into close contact with the upper wall 24, and the tip 48 is further curved up.

Therefore, the joint part of the front and rear roof plate members 14 and 15 has a hollow part 61 due to their joint, but if rainwater enters and accumulates in this hollow part 61, the water will freeze during the severe cold season and expand when it freezes. The joint may be damaged. In order to prevent this, a drainage hole 62 is provided by cutting out the inclined piece 41 and the overlapping piece 45. However, it is also possible to construct the side plate 20 so that the water accumulated in the hollow portion 61 is discharged from the side to the outside by means such as making holes in the side plate 20.

The bracket 19 is made by pressing an iron plate, and is formed into a substantially triangular shape, and has bending pieces 49 and 50 that bend in the same direction at a wide base end and a narrow tip at the top and bottom. The rivets 53 are screws. In addition to the hanging piece 54, the ceiling plate hanger 18 is also formed with a presser foot 55, a mounting piece 56, and a screw pocket 57.

The side plate 20 is in contact with the side surface of the upper arm 7, the side surface of the upper end of the front vertical frame 6, and the end surfaces of the front and rear roof plate members 14, 15, and is fixed with screws 58, 59. It is a screw pocket.

In the above configuration, among the front and rear roof plate members 14 and 15 that constitute the upper surface of the roof R, the rear roof plate member 15 not only has the mounting piece 36 nailed to the house H, but also is lowered by the support of the bracket 19. It is kept as if it were not. Further, the front roof plate member 14 has a hook portion 44 hooked on the lower surface protrusion 40 of the rear roof plate member 15, and the rear roof plate member 15
An engaging groove 46 is engaged with a downwardly directed hooking portion 42 . In other words, since the front roof board member 14 is connected to the rear roof board member 15 at two points, the load can be stably received there. Moreover, due to the form of the connection, the rear end and the overlapping piece 45 are connected to the rear roof board member 15. Pressure is applied to the surface by a load. Therefore, the front and rear roof plate members 14,1
Although the structure prevents rainwater from entering through the joint where the parts 5 are joined, even if rainwater enters the hollow part 61, it will escape through the drainage hole 62, pass through the connecting piece 37, and flow onto the upper frame 16. However, at the front end of the upper wall 24, the tip 48 of the inverted portion 47 of the front room root board member 14 is curved upward, and rainwater is blocked by it.
It flows down from the drain hole 31 provided in the upper wall 24 (arrow P). Furthermore, since the upper wall 24 is continuous with the vertical frame 6 at the point where the hollow portion 35 thereof opens, there is also a path for rainwater to fall into the hollow portion 35 and be discharged to the outside from the lower end (arrow Q). By the way, the drain hole 31 is provided in the upper wall 24 of the upper frame 16 on the outer wall 2.
6 and the engagement rail 28 of the outer shoji 4, rainwater flowing down from the drain hole 31 is inevitably drained to the outside. Moreover, since the drain hole 31 is shielded from stormy winds by the outer wall 26, the drain hole 31
Rainwater is drained smoothly from 1, and there is no risk of rainwater entering inside bay window A.

However, the location where the drain hole 31 is provided is not limited to the above-mentioned location;
3 and 64 are notched at the ends for drainage, so if the rainwater is transmitted through the vertical frame 21 and is led to the lower frame 22, the drainage hole 31 is located inside the engagement rail 28.
may be provided.

In the roof structure of the bay window according to this invention, the roof plate is made up of a combination of two front and rear roof plate members, and has a seam on the top surface, but the front end of the rear roof plate member is connected to the upper frame of the front frame of the bay window. We installed a connecting piece that protrudes from the top wall, so even if rainwater enters through the joint, it will flow down the connecting piece and onto the top frame.
Since rainwater is drained to the outside from the drain hole provided on the top wall, it is possible to take all possible measures to prevent rain from leaking into the bay window. Moreover, the rear roof board member is supported by the upper frame by this connecting piece, and since an inverted part that hangs on the upper frame is provided at the front end of the front roof board member, the stability of the combination of both the front and rear roof board members is ensured. There are remarkable effects such as:
