Description

[Detailed description of the invention] [Field of industrial application] This invention is used for daylighting of portable temporary buildings such as simple toilets at construction sites and shower rooms at beaches, or stationary buildings such as storage sheds and prefabricated houses. It's about structure.

[Prior Art] Conventionally, as a lighting structure in this type of building, structures in which a skylight for lighting is provided on the roof or a push-up window is provided in the upper part of the side wall have been widely used.

[Problems to be solved by the invention] By the way, in the case of conventional skylights and push-up windows such as those mentioned above, it is difficult to cover the window holes in the roof or side walls with daylighting boards, or to use window boards that can be opened and closed freely. Therefore, in order to increase the daylight area and brighten the interior, the window holes must be made larger. but,
Increasing the size of the window hole requires increasing the rigidity of the window frame accordingly, so in the case of mobile temporary buildings and stationary buildings with simple structures, etc., it is necessary to increase the rigidity of the window frame accordingly. The reality is that it is not possible to increase the lighting area.

In view of these conventional circumstances, the present invention has been developed to create a hollow double-walled structure made of light-transparent thermoplastic plastic for the structure constituting the roof or side wall of a mobile temporary building or a stationary building with a simple structure. By making a part of the window into a single-wall structure, the roof or side wall itself constitutes a daylighting window, simplifying the structure, and by providing an outer peripheral frame with a hollow double-wall structure around the daylighting area. It is an object of the present invention to provide a lighting structure for a building that can have sufficient rigidity even if the area of the lighting part is increased.

[Means for Solving the Problems] The present invention is configured as follows as a technical means for achieving the object.

That is, the structure is a construction board for a roof or side wall of a hollow double wall structure consisting of an outer wall and an inner wall of thermoplastic having light transmittance.
Lighting of a building in which a lighting section is formed with a part of the single wall, and the inner wall of the peripheral edge of the lighting section is welded to the outer wall to form an outer peripheral frame of a hollow double wall structure around the lighting section. It is a structure.

[Function] As described above, the lighting structure of the building according to the present invention is formed by forming a part of the hollow double-walled building plate constituting the roof or side wall as a single wall, and on the outer periphery of the lighting part. Since the outer frame part has a hollow double-wall structure, even if the area of this light-letting part is increased to increase the amount of sunlight, the surrounding outer frame part maintains high rigidity, increasing the strength of the construction board. is not impaired. Therefore, even if the daylighting area of the building is increased, the building as a whole maintains high strength.

[Example] An embodiment of the present invention will be described with reference to the drawings.

The drawing shows an example of a mobile temporary building. 1 is that building, and this building 1
The three sides except the front are made up of side walls 2, and a door 3 that can be opened and closed is attached to the front. 4 is its roof. These side walls 2 or the roof 4 are constructed of construction plates having a hollow double wall structure consisting of an outer wall 5 and an inner wall 6 made of light-transmitting thermoplastic plastic.

A lighting section 7 having a sufficiently large area relative to the total area of the roof 4 is formed in the center of the roof 4. That is, the lighting section 7 is formed by cutting out the inner wall 6 to form a single wall with high light transmittance, and the inner wall 6 that corresponds to the peripheral edge 8 of the lighting section 7 is welded and integrated with the outer wall 5, and the lighting section 7 is An outer circumferential frame portion 9 having a hollow double wall structure is formed around the portion 7. Therefore, even if the single-wall daylighting section 7 is formed to be large on the roof 4, the overall rigidity of the daylighting section 7 and the roof 4 is maintained.

Note that the lighting section 7 includes an inner wall 6 that does not cut out the inner wall 6.
This portion may be integrally bonded to the outer wall 5 to form a single wall structure with high light transmittance. Therefore, the thickness of the lighting section 7 is the same as the thickness of the outer wall 5 or thinner than the sum of the thickness of the inner wall 6.

On the other hand, in the building 1, daylighting portions 10 are also formed in multiple stages on the side wall 2 thereof.
This lighting section 10 is also similar to the lighting section 7 of the roof 4,
A part of the outer wall 5 is cut out or pressed onto the inner wall 6 to form a single wall structure with high light transmittance. The peripheral edge 11 of this lighting section 10 is also the outer wall 5.
The hollow double wall structure around the lighting section 10 forms an outer peripheral frame section 12.

As another embodiment of the present invention, the construction plates constituting the side walls 2 and the roof 4 are constructed entirely of light-transmitting thermoplastic plastic by blow molding as in the above embodiment, but as follows. It can be configured as follows.

That is, the outer wall 5 may be made of plastic with high light transmittance, and the inner wall 6 may be made of plastic with lower light transmittance than the outer wall 5. in this case,
The single-walled lighting section is formed by cutting out portions of the inner wall 6 that correspond to the lighting sections 7 and 10.

Alternatively, the parts corresponding to the lighting parts 7 and 10 may be made of plastic with high light transmittance, and the other parts not corresponding to the light collecting parts 7 and 10 may be made of plastic with low light transmittance. In this case, the single-walled lighting sections 7 and 10 can be obtained by cutting out the portions of the inner wall 6 that correspond to the lighting sections 7 and 10, or by crimping and integrating the portions of the outer wall 5 and inner wall 6 that correspond to the lighting sections 7 and 10. is formed.

Thermoplastic plastics constituting the construction board include polyethylene, polypropylene, polycarbonate, and the like. The thermoplastic plastic that makes up the construction board will have high light transmittance if no pigment is added or if a pigment is added that does not interfere with light transmittance.
In order to adjust the light transmittance, the amount of pigment added can be adjusted. In addition, to lower the light transmittance of the entire construction board, mix a light-blocking pigment, and to increase the light transmittance of only a part of it, avoid mixing the light-blocking pigment in that part. It can be implemented.

[Effects of the invention] The invention provides a lighting section with a part of it as a single wall in a construction board such as a roof or side wall of a hollow double wall structure consisting of an outer wall and an inner wall made of thermoplastic having light transmittance. The inner wall of the periphery of the lighting section is welded to the outer wall to form a hollow double-walled outer peripheral frame around the lighting section, so the lighting section cannot be made up of the roof or side wall itself. In order to simplify the structure, a hollow double-walled outer peripheral frame is formed around the daylighting area, which makes it possible to increase the area of the daylighting area and provide sufficient rigidity. A lighting structure that does not impair the strength of the light can be obtained.
