Abstract

<P>PROBLEM TO BE SOLVED: To solve the following problems: this type of conventional cylindrical built-up house is suitable for a cost reduction and the shortening of a construction period, because much labor and time are required for assembling work on site, on ground that various construction methods are used for the less general built-up house; a cut-off state cannot be easily brought about because water leakage probably occurs on ground that bending work is applied on site; and transportation, storage and assembly cannot be easily performed because each panel is too heavy, for the reason that the following low strength has to be made up for by the thickness strength of the panel, not only on ground that the trouble of maintaining panel connecting strength is required but also on ground that, particularly, load bearing capacity and resistance to an impact from a lateral direction are low, in terms of the strength. <P>SOLUTION: In this construction method, the cylindrical building of steel construction has strength high enough to be also used as a dwelling; the assembling work can be easily performed; and interior and exterior finishing materials can also be easily mounted. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a steel cylindrical building and an assembling method thereof.

Since this type of conventional cylindrical assembly house is not common, its construction methods are various, requiring labor and time for on-site assembly, and not suitable for cost reduction and construction period shortening.
In terms of strength, not only is it necessary to maintain the connection strength of the panel, but also because the load resistance and impact resistance from the side are particularly weak, it is necessary to compensate for this with the thickness strength of the panel. The weight of the panel became excessive, and transportation, storage and assembly were not easy.

  In addition, since conventional buildings are based on quadrangular shapes, they are all likely to have the same shape, and in the interior space of the quadrilateral, design research within that range has been exhausted and there is room for novel design. Is not left. Moreover, because there are many corners, it is easy to create a useless space and the cleaning efficiency is poor.

    When the circular outer wall and groundwork were constructed on site, the water leakage was highly established and the repair was very laborious and it was not easy to stop the water completely.

There exists patent document 1 as this improvement measure. However, although this method can be easily assembled, it is made of FRP, so the layout is not scalable and the strength is insufficient. Furthermore, in Patent Document 2, it can be used as a simple assembly facility such as a public toilet, but it cannot be said that sufficient strength is secured. Also, it is not suitable for residential use.

  The problem to be solved is to provide a method in which a steel-cylindrical cylindrical building has sufficient strength even for housing, an assembling work is easy, and an interior material and an exterior material can be easily attached.

In FIG. 4, after assembling a portal mast consisting of two steel main pillars 1 and steel beams 3 as a main mast, after fixing the mast foundation (i) with anchor bolts, the cylindrical building was divided into two vertically. Kamaboko-shaped dome-shaped walls are assembled on the ground, joined to the main mast with bolts to complete a cylindrical building foundation skeleton, and then solid concrete is placed.
A round aluminum panel is inserted into a steel circular beam with a circular aluminum panel clamp and fixed to the steel circular beam to place concrete. After placement, it can be used as an external skirting board.
Attach the anchor bolt to the steel circular beam and fix it to the solid foundation. By installing anchor bolts on the columns and beams, the building can be firmly fixed, and it can have a great effect on earthquakes and wind load stress, increasing the strength.
The surface of the roof panel can be covered with a fire-proof plate, waterproof and heat-insulated, and the back can be covered with a heat insulating material such as urethane foam to provide external and internal heat insulation. The interior can be kept comfortable by performing external insulation and internal insulation.
Fix the roof panel with panel base steel, steel beams, steel beams and steel lattice beams and bolts, adjust the water gradient with bolts, collect rainwater at the trough, and place rainwater eyes on both sides of the trough. It will be installed and drained with solid water, but the trough will be fixed with a trough fitting and will be waterproofed and insulated like the roof panel.
The roof panel and the outer wall material are fixed to the curtain plate wood with a curtain plate screw, the outer wall material is covered with an aluminum curtain plate, and water is sealed with a seal.
Steel beams are fixed to steel main columns with steel beams, steel beams are fixed to steel columns and steel beams, and steel circular beams are fixed to steel columns and main columns with high tension bolts. Can be arranged to form a triangle with steel large beams and steel small beams or steel lattice beams, and the half of the circle is formed as an integral beam, and the section modulus can be increased to reduce the individual beam members.
As a wall base material, a welded wire mesh is inserted between a welded wire mesh attachment metal mounted on the upper and lower sides of a steel circular beam and the steel circular beam, and is fixed by a welded wire mesh holding round steel which is easy to bend. Since the welded wire mesh uses a round steel lattice-shaped welded wire mesh, it is easy to bend, is lightweight, is inexpensive, and has sufficient strength. A body edge is fixed to the horizontal lattice portion of the welded wire mesh with a nail, and this body edge serves as a member for stopping the exterior material and the interior material.
The interior material is inserted into the gap between the steel circular beam and the metal fitting attached to the welded wire, and is mounted by sliding up and down, and the thickness can be adjusted with a cushioning material such as rubber packing, so that the interior material can be fixed with one touch.
As shown in FIG. 6, the first floor flooring is fixed with a bolt and bolted. As shown in FIG. 9, the floor material on the second floor is welded with a bolt to a structural member, attached with a large pull, and stretched. Attach the column cover panel and fix it to the body edge with the column cover panel stopper. The rain with the wall will be done with steel plate and sealing. The pillar cover panel uses a fire plate and is waterproof and insulated.
The problem to be solved is to provide a method in which a steel-cylindrical cylindrical building has sufficient strength even for housing, an assembling work is easy, and an interior material and an exterior material can be easily attached.

  Since the main parts are assembled and completed on the ground, the work to prevent water leakage, which is a fatal wound of the house, can be carried out completely in a place with good footing, so the water leakage will be much less than that of the existing house. Work at high places is reduced and the occurrence of falling accidents is reduced. Since the main parts such as the outer wall are assembled on the ground, the external scaffolding is also reduced. Up until now, circular buildings have been bending materials on-site and working on-site for a long time, and the on-site management was complicated, but this method only requires assembling factory-processed parts on-site, There is no need for skilled craftsmen, and the construction period can be shortened to one-third of the previous period, so the construction cost is greatly reduced, and there are many advantages that the site can be easily constructed even when the shape of the site is deformed and narrow.
