Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple building and its construction method.

[0002]

2. Description of the Related Art Conventionally, a prefabricated building has been known as a simple building that can be used in an event hall, an exhibition hall, a warehouse, a bar, and the like, and all of these are metal panel plates whose walls are made of lightweight steel. It has a structure with a roof and a floor inside if necessary. Also, recently, a log house made by stacking logs as a so-called woody house is used as a second house or a villa.

[0003]

Since a conventional prefabricated type simple building has a structure in which a metal panel plate is attached to a steel frame, when a large building is used, heavy objects are used for the steel frame or the number of steel frames used. However, even if it is a simple building, it requires a considerable number of construction days and construction cost. Further, in a large building, since the load applied to the beam becomes large, a middle pillar is required inside the building, and when a large internal space is required, such a middle pillar becomes an obstacle. In addition, the exterior design of the building also lacks flexibility, and in particular to construct a building with a curved surface such as a dome shape or a cylindrical shape, it is necessary to manufacture the panel board to be used with a planned curvature,
In fact, it is difficult to put it into practical use because it costs as much as or higher than that of the main building. On the other hand, log houses made by stacking logs have high material costs for the logs used, and also require considerable manpower and costs for assembly.
It is expensive. Further, in the case of constructing a log house having a curved surface such as a dome shape or a cylindrical shape, it takes time and labor to process and assemble the material, which further increases the cost.

Therefore, the present invention solves the problems in the conventional simple building of the pre-hap type and the stack type log house, which can be constructed at a low material cost and in a short period of time, and a free space of a required area can be further provided. At the same time, it aims to provide a building with a high degree of freedom in exterior design and its construction method.

To achieve the above object, according to the first aspect of the present invention, elongated tubular members are stacked on an outer peripheral foundation, and vertically adjacent tubular members are joined to each other. A building consisting of the formed wall structure is provided. Preferably, the wall structure may be configured in a circular or polygonal dome shape. Also, the elongate tubular member forming the wall structure may preferably consist of a thermoplastic. In the building of the present invention, the wall structure may be configured by joining another tubular member along one or both of the inside and the outside of the joint between the adjacent tubular members stacked. At least a part of the wall structure can be made of a transparent tubular member, or the ceiling part of the wall structure can be opened and a roof member can be provided at that part.

According to a second aspect of the present invention, in the method for constructing a building described above, elongated tubular members made of thermoplastic resin are sequentially stacked on an outer peripheral foundation while being bent into a required shape by a heating means, and are vertically adjacent to each other. It is characterized in that the tubular members are joined together by joining means to form a wall structure having a predetermined shape. The stacking of the tubular members on the outer peripheral foundation can be performed by spirally winding the tubular members with a predetermined curvature, or by stacking the tubular members one by one in an annular shape.

[0007]

In the building according to the first aspect of the present invention configured as described above, since the wall structure constructed on the outer peripheral foundation is constructed by stacking the elongated tubular members,
There is no need for a support such as a support pillar inside,
A space having a desired size and shape can be formed inside. In addition, a so-called wedge action can be obtained between the adjacent tubular members that are overlapped and joined to each other, and sufficient proof strength against self-weight, snow, rain, wind, etc. can be obtained. Further, by bending the tubular member to be used, it can be formed into an arbitrary outer shape such as a circular shape, a spherical shape, or a polygonal dome shape. When a transparent material is used for the tubular member, sunlight or the like can be taken inside. In the construction method according to the second aspect of the present invention, a long (for example, several tens of meters long) elongated tubular member made of a thermoplastic resin, which is usually provided in a state of being wound on a reel, is used at a construction site. It can be placed on the foundation by being sequentially heated by a heating means while being fed onto the foundation, being bent into a predetermined shape. In this case, as the heating means, there is used a heat radiation part inside the heating passage through which the tubular member is passed, and a type that heats the tubular member from the outer periphery or a type that heats the tubular member from the inside by supplying a heat medium. can do.
