DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kamakura suitable for commercial use such as a store at various event venues held in winter, a method of manufacturing the same, and a connecting jig used for the manufacture.

[0002]

2. Description of the Related Art Kamakura, a northern tradition, is produced not only for personal enjoyment but also for various events and events. Various methods are known for manufacturing a kamakura. The easiest way is to pile up and harden the snow and hollow out the interior. There is also a method of assembling a pole, hanging a sheet on the pole, and stacking snow on it to solidify it. Another method is to build a kamakura by stacking blocks of ice.

[0003]

However, each of these methods takes a long time to manufacture, so that the cost is high and there is a problem in using it for commercial use. Further, in the method using the above-mentioned pole, there is a disadvantage that the outer shape of the kamakura becomes irregular.

Accordingly, it is an object of the present invention to provide a kamakura, a method of manufacturing the same, and a connecting jig which can be manufactured relatively easily in a short time.

And a pentagonal or hexagonal roof template is combined with the upper part of the peripheral wall to form a temporary shape of the dome-shaped roof, and corresponds to the peripheral wall template and the roof template. A block piece made of a snow or ice block having a shape to be formed is stacked and joined in accordance with the peripheral wall template and the roof template.

A method of manufacturing a kamakura according to a second aspect of the present invention includes the steps of: erecting a plurality of peripheral wall templates on the ground while detachably joining them together to form a temporary shape of the peripheral wall portion;
After the pentagonal or hexagonal roof template is detachably joined to the peripheral wall template, the pentagonal or hexagonal roof template is detachably joined to the pentagonal or hexagonal roof template sequentially according to a predetermined procedure. A step of forming a temporary shape of the roof portion, and adding at least one of snow and ice to the formwork, and a block piece made of a snow or ice block corresponding to the shapes of the peripheral wall template and the roof template. And bonding the block pieces to each other while sequentially stacking the block pieces along the peripheral wall template and the roof template.

According to a third aspect of the present invention, there is provided a connecting jig comprising: a fixing portion attached to a back surface of the adjacent peripheral wall template, the roof template; and an arm portion connecting the fixing portions. And an attaching / detaching means for detaching the arm portion from the template.

If the inside dimension facing P is P7, the following expression is satisfied. P2 = P1 / cos (111 ° -90 °) P3 = P1 / tan71 ° P4 = P7 × sin58 ° P5 = P7 × cos61 ° / cos58 ° P6 = P7 / cos58 °

FIG. 8 is a plan view of a mold frame 34 used when forming the block pieces 20. The mold 34 has a size obtained by dividing the above-described mold 32 into two. A wall 34B rising from the bottom 32A corresponds to the wall 32B, and a wall 34C corresponds to the wall 32C. Have.

The ribs for reinforcement may be formed on the periphery of the wall of each mold shown in FIGS. Thereby, since the rigidity of the mold body is improved, when the molded block piece is removed from the mold or when the mold is frozen, deformation of the mold can be reduced, and the durability of the mold can be improved. It is possible to improve the accuracy of the formed block piece.

Next, a method of manufacturing the kamakura shown in FIG. 1 will be described. FIG. 9 is a front view showing a state where a temporary shape of a kamakura is formed by joining the templates, FIG. 10 is a plan view of FIG. 9, and FIG. 11 shows a joining state of the templates viewed from the inside. FIG.

As shown in FIGS. 9 and 10, first,
Peripheral wall templates 40, 41 formed by plywood or the like into dimensions and shapes corresponding to the block pieces 16, 17A, 17B are erected on the ground. At this time, the inner part of each adjacent template is
Using a connecting jig to be described later, they are connected to each other to form a temporary shape of the kamakura peripheral wall portion. Thereafter, the temporary shape of the roof is assembled. First, five pentagonal roof templates 42 are provided on the upper part of the peripheral wall template 40, and four pentagonal roof templates 44 are provided on the peripheral wall template 41. And joining alternately with a connecting jig. Further, a total of five hexagonal roof templates 46 are
The two roof templates 42 and the top side of the roof template 44 are joined in contact with each other. In addition, the adjacent roof template 4
6 are similarly joined with a connecting jig. Finally, the temporary shape of the roof is formed by joining the pentagonal roof template 42 to the five roof templates 46.

FIG. 11 is a view of the joining state of the template plates by the connecting jig 50 as viewed from the entrance. As shown in FIG. 11, the connecting jig 50 includes the peripheral wall templates 40, 41,
Fixed part 52 attached to the back of roof templates 44, 46
And an arm 54 connecting the fixed parts 52. The fixing part 52 is attached to a predetermined position on the back surface of each template in advance. The arm portion 54 is formed to be curved at a predetermined angle, and is detachable by a fixing screw 56 having a fixing handle provided on the fixing portion 52. Therefore, when connecting each template, if the fixing screw 56 is screwed together with the fixing portion 52 so that the mounting hole of the arm portion 54 is aligned, the arm portion 54 is fixed to the fixing portion 52, and as a result, The template plates are connected to each other.

Next, block pieces previously formed by the above-described molds are stacked and joined to a temporary shape pillow formed by using a template as described above. Specifically, first, the block piece 1 is supported by the peripheral wall template 40 as a support.
6 is fixed on the ground, and the peripheral wall template 4 is also fixed.
With the support 1 as a support, the side surfaces of the block pieces 17A and 17B are joined, and the adjacent block piece 16 and the side surfaces are joined. At this time, since the side faces of the block pieces 17A and 17B and the side face of the block piece 16 are formed at a predetermined angle, the block piece 16 and the block pieces 17A and 17B are formed.
Are joined at a predetermined angle. By repeating such operations, the peripheral wall portion 12 is formed. Then, the block pieces 18, on the roof templates 42, 44, 46,
The roof part 14 is formed by sequentially joining 20 and 22, thereby completing the kamakura 10 shown in FIG. 1. For joining the block pieces, snow or sherbet-shaped snow obtained by adding an appropriate amount of water to snow can be used.

As described above, according to the kamakura of the present embodiment and the method of manufacturing the same, the temporary shape of the kamakura is formed in advance by the template, and the block piece formed in advance by the mold is utilized by using the template. Kamakura is manufactured by joining them sequentially while overlapping. For this reason, it is possible to manufacture the sleeper quickly and at low cost. In addition, the template plates can be quickly connected and removed by the connecting jig, which contributes to shortening of the manufacturing time of the kamakura.

[0028]

According to the first and second aspects of the present invention,
Kamakura that can be used for commercial facilities at various event venues and the like can be manufactured in a short time and at low cost.

According to the third aspect of the present invention, it is possible to quickly connect and remove the mold plates forming the temporary shape of the kamakura, and to further reduce the time required for manufacturing the kamakura.
