Description

[Detailed explanation of the idea] The present invention relates to an improvement of a dome-shaped building.

Dome-shaped buildings have been used for stores, rest areas, residences, warehouses, etc., but the top of the frame and the outer walls are always problematic in their construction.

In other words, at the top of the frame, a large number of arch columns must be connected together, making the structure complicated, and as the frame structure at the top becomes complicated, it becomes difficult to provide openings for lighting and ventilation at the top. It becomes difficult.

In addition, in order to construct an exterior wall, generally reinforcing bars are curved and arranged vertically and horizontally between each arch column and each vertical frame, then felt is stretched over it, lath is stretched, and mortar is painted. However, with this method, it is time-consuming to bend the reinforcing bars along the dome shape, it is time-consuming to stretch and fix the felt and lath along the dome shape, and it is difficult to apply mortar. It requires a high degree of skill and skill to construct the dome so that it has a uniform thickness and a smooth dome shape, and is time-consuming.

Therefore, a lot of labor and time were spent on constructing the outer walls, resulting in extremely poor construction efficiency.

Moreover, it is difficult to construct the interior directly on the inner surface of the mortared outer wall, which is prone to peeling, so reinforcing bars are bent and placed vertically and horizontally between each arch pillar and between each rim, just like in the case of the outer wall. However, since the interior was made of appropriate materials on top of that, a space layer was formed between the interior and exterior walls, making the walls of the dome-shaped building thicker and reducing the interior space compared to the exterior dimensions. There were problems such as narrowness.

The present invention was made to solve these problems, and has a structure that allows multiple arch columns to be easily connected at the top, has openings for lighting and ventilation, allows wiring to be introduced inside through the arch columns, and allows for easy connection of a large number of arch columns at the top. This is an improved dome-shaped building that can be constructed easily and quickly, has high construction efficiency, and can be constructed so that the inner wall can be built directly on the inner surface of the outer wall, making it possible to use the interior space effectively without reducing it. This is what we intend to provide.

It is clamped and fixed to.

As shown in Fig. 6a, the flange 21 on the left side of each concrete panel in the middle and high areas overlaps with the flange 22 on the right side of the adjacent concrete panel, beyond the arch column 2, and the flange 22 on the lower side It is supported on the middle furrow 14.

The flange 21 on the upper side of each lower concrete panel is superimposed on the lower vertical plate 14b of the middle tier 14 and the flange 22 on the lower side of each middle and high concrete panel, and a flange 21 is provided on the inner surface of the flange 21. The embedded nuts 23 and the through holes 14C of the rim 14 are aligned, and the bolts 25 are screwed into the embedded nuts 23 through the through holes 14C. It is clamped and fixed between the flange 21 on the upper side of each lower concrete panel and the upper vertical plate 14a of the rim 14.

In the dome-shaped building of the above embodiment, the arch columns 2 are made of round pipes, but they may also be made of square pipes.

The main body of the top ring 5 is a circular cylinder 6, but it may also be a polygonal cylinder.
are provided on each surface of the outer periphery of the cylinder.

Furthermore, although the cylinder 6 is an upright cylinder, it may be replaced with a cylinder whose vertical cross section is a mortar shape with an expanded upper part in order to let in more light.

Furthermore, the concrete panels are curved in the left-right direction by an arc centered on the axial center line of the dome-shaped frame 15, and furthermore, the concrete panels stretched in the middle and upper parts are vertically curved along the arch pillars 2. Although curved, these concrete panels may also be flat.

Of course, in that case, the flanges on each side that connect adjacent concrete panels in a superposed manner are bent as appropriate.

Further, adjacent concrete panels in the left and right direction may be connected and fixed not only to the upper concrete panel but also to the middle and lower concrete panels using embedded nuts 23 and bolts 25.

Further, the lower concrete panel may be provided with a skirt 33 at the bottom, as shown by the chain line in Fig. 5, so that when the diameter of the concrete base 1 is reduced, it can cover the outer peripheral surface of the concrete base 1 and drain water. In addition, when the lower end of the flange 21 on the lower side of the concrete panel is brought into contact with the finished floor 1a of the concrete base 1 as shown by the solid line in FIG. It is preferable to provide a border 34 as shown in FIG.

As can be seen from the above explanation, the dome-shaped building of the present invention can connect the upper ends of a large number of arch columns at the top to the outer circumferential surface of a top ring whose main body is a cylindrical body with openings at the top and bottom ends using only bolts and nuts. , the arch columns can be easily assembled, the frame structure at the top is simplified, and a transparent canopy is attached to the flange at the top of the top ring, allowing for sufficient lighting.
Furthermore, since a ventilation tube is provided on the outer circumferential surface, there is no problem with ventilation.

In addition, since the arch pillar is connected to the top ring by communicating with the through hole drilled in the outer circumferential surface of the top ring, wiring, etc. passed through the arch pillar can be introduced into the inside of the top ring, and therefore the lower end of the top ring When the lighting equipment is hung, its power cord can be connected to the wiring as appropriate, which is very convenient.

In addition, the dome-shaped building of this invention has an outer wall with doors, windows,
It consists of concrete panels that have openings such as bay windows and concrete panels that do not have openings, and these concrete panels are arranged in sections divided into arch pillars and rims, respectively, and adjacent ones are arranged as appropriate. Since they are connected by flanges provided on each side through the arch pillars and rims, the outer wall is a panel unit and can be easily stretched and fixed to the dome-shaped frame, making it possible to Compared to the construction of exterior walls, the mortar coating allows exterior walls to be constructed more easily and quickly, resulting in extremely high construction efficiency.

Moreover, since interior decoration can be applied to the inner surface of the concrete panel, no space layer is formed between the exterior wall and interior wall, so the interior space of the dome-shaped building can be used effectively without shrinking. There are effects such as obtaining.
