Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a prefabricated house having a novel roof structure in which a ventilation window or a daylight window is formed at the top of the roof, or solar cells are arranged.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Fig. 1 shows an embodiment of the present invention in which trapezoidal trusses are used for all of the trusses 1 for constructing the roof, and a ridge part 2 in the shape of a triangular prism, for example, is attached to the upper side 1a of the truss 1. It is mounted so that its axis coincides with the column direction. The ridge part 2 is constructed by connecting a plurality of small triangular trusses with horizontal beams. In this case, the width of the lower side 2a of the ridge part 2 is the same as that of the trapezoidal truss 1.
It is desirable that the length of the upper side 1a be equal to the length of the upper side 1a. In addition, the ridge part 2 is attached to the upper side 1 of the trapezoidal truss 1.
A can be attached to the lower chord part 2a of the ridge part 2 by connecting the lower chord part 2a of the ridge part 2 to the upper chord part 1a of the trapezoidal truss 1 with bolts and nuts.

However, in such prefabricated houses,
Since the top of the roof protrudes, it is possible to effectively concentrate sunlight when placing solar cells on the left and right slopes 2b and 2c of the ridge part 2, and it is effective when pasting a transparent glass plate. It is possible to construct a daylighting skylight that allows for natural light. Furthermore, by configuring the skylight so that it can be opened and closed, it can also be used as a ventilation window. Furthermore, the internal space of this ridge part 2 can also be used, for example, as a storage space. FIG. 2 is a diagram showing a state in which solar cells are arranged on the slopes 2b and 2c of the ridge part, or a skylight for daylighting or ventilation is constructed. Reference numeral 3 in the figure indicates roofing material covered on the left and right hypotenuses 1b, 1c of the trapezoidal truss.

3a, b and 4a, b respectively show other embodiments of the present invention, and FIGS. 3a and 4a are both schematic configuration diagrams showing the relationship between the roof truss and the ridge parts. , FIG. 3b, and FIG. 4b are both schematic perspective views showing the completed state. In these figures, the same reference numerals are given to the same constituent members as those in the embodiment shown in FIG. 1.

Figures 3a and b are examples where a semi-cylindrical truss is used as the ridge part 2, and Figures 4a and b are examples where a trapezoidal truss is used only for a part of the roof, and a triangular prism-shaped truss is used on the upper side of the trapezoidal truss. An example in which the ridge part 2 is attached as a crown is shown. In each of these embodiments, all or part of the roof top protrudes due to the presence of the ridge part 2, so the protruding part can be used to effectively collect sunlight, light, ventilate, etc. can.

As described above, in the prefabricated house according to the present invention, a trapezoidal truss is installed on at least a part of the roof, and a triangular prism-shaped or semi-cylindrical ridge part is placed on the upper side of the trapezoidal truss, and its axis line and girder row direction coincide with each other. At the same time, a solar cell and a skylight for lighting or a skylight for ventilation are provided on the outer surface of the ridge part, so if a solar cell is installed on the outer surface of the ridge part, can effectively concentrate sunlight and maximize its effect. Therefore, it can contribute to resource saving. In addition, if a skylight for lighting is installed on the outer surface of the ridge part, it will be possible to effectively bring in light indoors, and if a skylight for ventilation is installed, it will be possible to effectively ventilate the indoor area, which will improve health. It can provide a bright living space. Furthermore, since the ridge part is attached to the upper side of the trapezoidal truss, sunlight can be captured no matter which direction the house itself is facing, and the above-mentioned light concentration or lighting can be reliably achieved. Therefore, each of the above-mentioned effects can be achieved regardless of locational conditions. In addition, the ridge parts are triangular prism-shaped or semi-cylindrical and are pre-assembled before being attached to the roof truss, so it is possible to attach solar cells to the ridge parts, skylights for daylighting, or skylights for ventilation. The installation can be done in a safe place such as on the ground at a factory or site without having to do it on the dangerous roof. Therefore, the work of attaching the crown of the ridge part and the work of attaching the solar cells, etc., are easy, and the safety of the workers can be ensured.
