Description

TECHNICAL FIELD The present invention relates to a prefabricated building such as a prefabricated sunroom.

2. Description of the Related Art As an awning device for an assembled sunroom, there is known an awning device having a winding shaft rotatably arranged inside a rear portion of a roof and a awning sheet wound around the winding shaft. . Further, as a heat retaining device for an assembly type sunroom, there is known one having a winding shaft rotatably arranged inside a rear portion of a roof and a heat retaining sheet wound around the winding shaft. The awning sheet is a colored sheet and the heat insulation sheet is a transparent sheet. Generally, sunshades are used in the summer and heat retaining devices are used in the winter. In the conventional sun protection device and heat retention device, both devices have to be replaced in the summer and winter, and the replacement work is troublesome.

An object of the present invention is to provide a transparent prefabricated building that solves the above problems.

Means for Solving the Problems In a prefabricated building according to the present invention, a winding shaft is rotatably mounted inside a front part and a rear part of a transparent roof,
The front end of the combined sheet consisting of the heat insulating sheet and the sunshade sheet with the end portions connected to each other is wound around the front winding shaft, and the rear end of the combined sheet is wound around the rear winding shaft. Is longer than the distance between the two winding shafts.

When the sunshade is required, the heat insulating sheet is wound around the take-up shaft, and the sunshade sheet is stretched between the take-up shafts. On the other hand, when heat retention is required, the shade sheet is wound around the winding shaft, and the heat retention sheet is stretched between the winding shafts.

Embodiment Hereinafter, referring to the drawings, the present invention can be applied to a vertical wall of an existing house.
An example in the case of being applied to a prefabricated sunroom connected to the house by contacting the outer surface of (W) will be described.

The roof (1) of the prefabricated solarium has a rear frame member (2) fixed to the wall (w) of an existing house and a front frame member (3) having a gutter (3a).
, Both side members (4), a plurality of first reinforcing members (5) which are retained by the rear frame member (2) and the front frame member (3), both side members (4) and the first member adjacent thereto. A plurality of second reinforcing members (6) which are fixed to the reinforcing member (5) and between the adjacent first reinforcing members,
Between the rear frame member (2) and the front frame member (3) and both side members
A plurality of transparent plates (7) are provided between (4) and the adjacent first reinforcing member (5) and between the adjacent first reinforcing members (5).

A first winding device (10) extending in the left-right direction is attached to the rear surface of the front frame member (3). On the wall (w), the rear frame member (2)
A second winding device (20) extending in the left-right direction is attached to the lower side of the. Each winding device (10) (20) has a tubular casing (1) having sheet winding / feeding ports (11a) (21a) facing each other.
1) (21) and a winding shaft (12) (22) arranged in the casing (11) (21) and rotatably attached to the casing (11) (21)
It has and.

Then, the joining sheet (30) consisting of the heat insulating sheet (31) (shown by a broken line) and the awning sheet (32) (shown by a solid line), to which the end portions are connected, is the sheet winding / winding sheet for the casing (11) (21). The winding shafts (12) and (22) are passed over the feeding ports (11a) and (21a). That is, the front part of the binding sheet (30) is the first winding shaft.
The rear part of the coupling sheet (30) is wound around the second winding shaft (22) on the (12). The front end of the joining sheet (30) is fixed to the first winding shaft (12), and the rear end thereof is fixed to the second winding shaft (22). The front and rear lengths of the heat insulating sheet (31) and the shade sheet (32) are longer than the distance between the winding shafts (12) and (22). As the heat retaining sheet (31), for example, a transparent vinyl chloride sheet is used. As the shade sheet (32), for example, a colored polyester sheet is used.

When it is necessary to keep the sunroom warm, the sunshade sheet (32) may be wound around the second winding shaft (22) as shown in FIG. 1 so that the heat insulating sheet (31) is stretched. When it is necessary to shade the sunroom, as shown in Fig. 2, the first winding shaft
Wind the heat insulation sheet (31) around (22) and shade the sheet (32)
It should be in a stretched state. When neither heat retention nor awning is required, the binding sheet (30) may be wound around one of the winding shafts (12) (22).

Effect of the Invention In the prefabricated building according to the present invention, it is possible to easily switch between the heat insulation sheet and the shade sheet.
