Description

[Detailed description of the invention] This invention relates to a sunroom that is connected to the outside of a building.

Conventionally, this type of sunroom using aluminum alloy shapes and steel shapes has been implemented in general houses, etc., but most of them have a depth of around 1 cm, and the aluminum alloy shapes used for them are Shaped steel rafters are also uniformly mass-produced products that are designed to be strong enough to fit a depth of about 1 ken, so if a sunroom with a large depth is created according to the resident's wishes, a new one is required. Strong rafters had to be prepared separately, which was economically disadvantageous.

This project provides a sunroom with a large depth dimension that allows the use of conventional, inexpensive mass-produced rafters. It is formed by an external roof part having a roof part, and each end of both roof parts in the step part is supported by a reinforcing member supported in the sunroom. Embodiments of the present invention will be described below with reference to the drawings.

In Figures 1 and 2, a sunroom S connected to the outside of a building F consists of a wall part 1 made of a frame material supporting a transparent glass plate, left and right end side walls 2 and 3, and a roof part 4. , the roof section 4 has a short building side roof section 5 which is fixed at one end to the outside surface of the building and extends outward with a downward slope, and a position below the lower end of the roof section 5 in the inclination direction with an appropriate step. and a long external roof part 6 that extends outward from the roof part 6 at a downward slope. The upper end portion of the outer roof portion 6 in the slope direction is supported by a reinforcing structure within the sunroom S.

As shown in the fourth and fifth figures, the building side roof part 5 is made of short horizontal frame members 7 and 8 made of aluminum alloy shapes and a short vertical frame member 9 obtained by cutting from a conventional vertical frame member having a length of 1. , 10 in a unit frame framed by glass 1
The roof units 5' are formed by watertightly fitting the roof units 5', which are adjacent to each other in the left and right direction, and are connected by screws 12. A vertically long roof unit 6' is formed by fitting a glass 17 into a unit frame framed by short horizontal frame members 13, 14 having the same cross-sectional shape as 8 and vertical frame members 15, 16 made of conventional vertical frame members having a length of one room. …
are connected in the same way as the building side roof part 5.
The vertical frame members of each roof unit are connected to the vertical frame members of the adjacent roof unit by screws 12 to form roof rafters.

The roof support structure at the roof step is as follows. In the sunroom S, the first, second,
3. As shown in Figure 3, section steel columns 18, 18 are vertically erected at positions close to the inner surfaces of both gable side walls 2, 3 below the stepped portion, and I-shaped columns are installed at the upper ends of the columns 18, 18. Both ends of the steel reinforcing cross member 19 are supported and fixed in a horizontal state, and at both ends of the reinforcing cross member 19, there are braces 20, one end of which is fixed to the building F.
The other end of 20 is fixed. Anchors 21 are welded onto the reinforcing cross members 19 set in this way at positions corresponding to the respective roof units 5' of the building side roof 5 as shown in the fourth figure, and connecting pieces 22 welded to these anchors are welded to the reinforcement cross members 19. The horizontal frame members 8 on the lower side in the inclination direction of each roof unit 5' are fixed to... with screws 23..., and each roof unit 6' of the external roof part 6 is fixed to the outer side of the reinforcing horizontal member 19. Anchors 24... are respectively welded to positions corresponding to..., and the horizontal frame member 13 on the upper side in the inclination direction of each roof unit 6' is locked to the connecting piece 25... welded to these anchors.
As a result, the lower end in the inclination direction of each roof unit 5' of the building-side roof part 5 and the upper end in the inclination direction of each roof unit 6' of the external roof part 6 are in a state in which there is a vertical step between them. It is supported by the reinforcing cross member 19. 26 is the building side roof part 5 at the step part.
It is a closing plate extending over the entire length of the roof that closes between the lower end and the upper end of the external roof 6, and its upper side is attached to the horizontal frame member 8 of each roof unit 5' with screws 27.
..., and the lower side portions are fixed to the horizontal frame members 13 of each roof unit 6' through brackets 28 with screws 29. 30 is a caulking material.

The other embodiment shown in FIGS. 6 and 7 includes a building side roof portion 5a consisting of relatively vertically elongated roof units 5'a, and roof units 6'a, which are approximately the same length as the roof portion 5a.
This is an example in which the external roof part 6a consisting of a roof part 6a is supported by a reinforcing horizontal member 19a with a step. The horizontal frame members 8a of each roof unit 5'a are fixed to the connecting pieces 22a which are welded to the anchors 21a, respectively, with screws 23a, while the anchors 24a which are welded to the outer surfaces of the support bases 41a are A C-shaped locking portion 43a in the cross section is attached to each welded connecting piece 25a.
The support frame 42a... having the arch-shaped overlapping portion 44a is fixed with screws 45a..., and is attached to the horizontal frame member 13a... of the roof unit 6'a...
A shape locking portion 46a and an arcuate overlapping portion 47a are respectively formed, and while the locking portion 46a is locked to the locking portion 43a, the overlapping portion 47a is overlapped with the inside of the overlapping portion 44a, and the upper and horizontal portions of the wall portion 1a are A C-shaped locking portion 49a and an arc-shaped overlapping portion 50a are formed in the cross section of the frame 48a, and the horizontal frame member 1 of the roof unit 6'a...
A C-shaped locking portion 51a and an arc-shaped overlapping portion 52a are formed in the cross section of each of the locking portions 49.
a, 51a are engaged, and the overlapping portions 50a, 52a are overlapped. The other structure is substantially the same as the above example. In this example, various inclination angles can be set by swinging the external roof part 6a about the locking parts 43a, 46a, 49a, and 51a.

The building side roof part may also have a structure with a freely tiltable structure similar to the above-mentioned external side roof part 6a.

According to this sunroom with great depth,
By using mass-produced rafters that are designed to be strong enough to accommodate conventional depths of about 1 ken, it is now possible to provide sunrooms with wide roofs that are 1 ken or more deep at low cost, making it more economical. This is particularly advantageous, and since the roof is formed with a step difference between the building side roof and the exterior side roof, the glass on both roofs are not connected in the direction of inclination and can be installed separately. Another advantage is that the glass can be easily installed and replaced.
