本発明は、構築物の底端部材の外縁をシールする構造に
係り、例えば貯油タンクのアニユラ−板゛をら一ルＪ゛
るために利用できるものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a structure for sealing the outer edge of a bottom end member of a structure, and can be used, for example, to seal an annular plate of an oil storage tank. It is possible.
Ｌ背景技術とその問題点〕
屋外に設置される貯油タンクを腐食させる原因の中で最
も多いと言われているものは、貯油タンクの底端部材で
あるアニユラ−板の裏面に雨水が侵入することである。L Background technology and its problems] The most common cause of corrosion in oil storage tanks installed outdoors is rainwater entering the back side of the annual plate, which is the bottom end member of the oil storage tank. That's true.

により底端部材の縁部をシールするシール剤が開発され
、貯油タンクのいわゆる犬走り部分に施工されている。According to the Fire and Disaster Management Agency notification, measures must be taken to prevent rainwater from entering the lower part of the tank through the outer protrusion of the annular board, etc. Based on this notification, many manufacturers have developed sealants for sealing the edges of the bottom end member, and these are applied to the so-called dog-legged portion of the oil storage tank.

れる。The fourth circle is a vertical cross-sectional view of the bottom of the oil storage tank without showing the conventional sealing structure using a sealant, and the oil storage tank 1 is installed on the foundation ground 2. This foundation ground 2 is made by laminating fine-grained asphalt concrete 4 on top of a pebble layer 3, asphalt mortar 5, and fine-grained asphalt concrete 6. I! A groove 8 is provided in the ground 2 at the peripheral edge of the annular plate 7 of the oil storage tank 1, and a buffer portion +49 is disposed in this groove 8. A sealing member 40 is attached to the outer edge of the annular temporary 7 and a base material 4 is provided between the annular plate 7 and the outer edge of the annular temporary 7.
1. The sealing member 40 is placed between the annular plate 7 and the fine-grained asphalt concrete 6 via a base agent 42, and the edge of the annular plate 7 is sealed to prevent rainwater from entering.

大きなものとなる。In the above, when oil is poured into and drained from the oil storage tank 1 and the liquid level moves up and down, the bottom of the oil storage tank 1 is repeatedly subjected to both vertical and horizontal loads due to changes in oil pressure. act. Such repeated loads in the horizontal direction are also caused by changes in oil temperature and outside temperature, and changes in outside temperature can be large depending on the region where the oil storage tank 1 is installed.
以上のような荷重によりアニユラ−仮７、さらには基礎
地盤２は貯油タンク１の内外方向に伸縮せしめられる。Due to the above-mentioned loads, the temporary annular 7 and furthermore the foundation 2 are made to expand and contract in the outward and outward directions of the oil storage tank 1.

ていた。However, in reality, according to the conventional seal structure, the elastic deformation of the seal member 40 does not correspond to the expansion and contraction movement of the annular temporary 7, and therefore, as shown by the chain line 40, the elastic deformation of the seal member 40 The fine-grained asphalt concrete 6 peeled off, and the fine-grained asphalt concrete 6
A crack 43 may occur in the annular plate 7, and the sealing member 4° may peel off from the annular plate 7 as shown by the chain line 40''.As a result, the sealing by the sealing member 40 is incomplete, and the back side of the annular temporary plate 7 is damaged. There was a problem with rainwater infiltrating.
本発明の目的は、シール部材によるシール効果を高め、
アニュンー仮等の底端部材の裏面に雨水等が侵入するの
を確実に防止できるようにするところにある。The purpose of the present invention is to enhance the sealing effect of the sealing member,
The purpose is to reliably prevent rainwater etc. from entering the back surface of the bottom end member of the Annun temporary.

に延びる内方突出部を設けている。[Means and effects for solving the problem] Therefore, in the first invention, a buffer member is arranged at the peripheral edge of the bottom end member of the structure on the foundation ground on which the structure is installed, and the edge of the bottom end member is sealed. In the sealing structure of the bottom end member of a construction sealed with a member, the sealing member is provided with an inward protrusion extending to the back surface of the bottom end member.
この内方突出部により底端部材の裏面端部もシール部材
によってシールされ、たとえ底端部材の外側面からのシ
ール部材の剥離等が生じても底端部材の裏面への雨水の
侵入は阻止される。Due to this inward protrusion, the back end of the bottom end member is also sealed by the sealing member, and even if the sealing member peels off from the outside surface of the bottom end member, rainwater will be prevented from entering the backside of the bottom end member. be done.
第２の発明では以上の第１の発明の内容に加えるに、シ

耐熱耐寒性、耐候性を存する。When the groove 11 is filled with the sealing member 14 as described above, the edge of the annular plate 7 is sealed, and the notch 11 is sealed.
The seal member 14 filled in A forms an inward protrusion I4A extending to the back surface of the annular plate 7, and the back end 7B is also sealed by this inward protrusion 14A. After the sealing member I4 is dried, the covering member 15 is placed on the surface of the sealing member 14. This covering member 15 is FRS coat (trade name, manufactured by Komei Co., Ltd.). This covering member 15
It is made of polyester fiber and silicone rubber and has excellent heat resistance, cold resistance, and weather resistance.

−板７の裏面側に侵入するのを防止できる。When the above-described sealing structure is adopted, not only the side surface of the edge of the temporary annular 7 is sealed by the sealing member 14, but the inwardly protruding portion 14A of the sealing member 14 is sealed.
Since the back side of the edge of the annular plate 7 is also sealed,
Annular plate 7 due to vertical movement of the liquid level in oil storage tank 1, etc.
, horizontal repeated loads act on the asphalt mortar 5 of the foundation ground 2, and as a result, for example, the sealing member 14 may peel off from the outer surface 7A of the annular plate 7, even if the side surface of the edge of the annular plate 7 is peeled off. Even if the seal of
The seal on the back side of the edge of the annular plate 7 can be kept intact, and rainwater can be prevented from entering the back side of the annular plate 7.
また、シール部材１４に内方突出部１４Ａを設けること
によりシール部材１４七アニユラ−仮７との接触面積が
その分だけ大きくなり、シール部材１４がアニユラ−板
７から剥離しにくくなるという効果も期待できる。Further, by providing the inwardly protruding portion 14A on the sealing member 14, the contact area of the sealing member 14 with the annular plate 7 becomes correspondingly larger, which has the effect that the sealing member 14 becomes difficult to peel off from the annular plate 7. You can expect it.

ため、永続的なシールを達成できる。Furthermore, as mentioned above, by using a sealant with large expansion and contraction deformation properties for the seal member 14, the seal member 14 can sufficiently follow the expansion and contraction movement of the annular plate 7 in the outward and outward directions of the oil storage tank 1. Also, peeling of the seal member 14 from the annular handle 7 can be effectively prevented. Furthermore, by covering the surface of the sealing member 14 with the covering member 15, the sealing member 14 is protected from outside temperature, etc., and the characteristics of the sealing member 14 are guaranteed for a long period of time, so that a permanent seal can be achieved. It can be achieved.

る。Further, in this embodiment of the third invention, as in the embodiment of the first invention, the seal member 14 does not have a length exceeding the buffer member 12, and the length of the seal member 4 is extended to the outside of the oil storage tank 1. The length is up to the buffer member 12. A groove 30 is provided in the fine-grained asphalt concrete 6 of the foundation ground 2 at the peripheral edge of the seal member 14, and a buffer member 3 is provided in this groove 30.
Place 1. Therefore, in this embodiment, the buffer member 12 is the first buffer member, while the buffer member 31 is the second buffer member. The material of the second buffer member 31 is the material of the first buffer member 12.
It is the same as the above-mentioned Sambelka polyethylene L-1400.

くなる。In this embodiment, when the expansion and contraction movement of the annular plate 7 in the outward and outward directions of the oil storage tank 1 is transmitted to the sealing member 14,
The expansion and contraction movement of the seal member 14 is absorbed by the second buffer member 31 and is no longer transmitted to the fine-grained asphalt concrete 6 on the side of the second buffer member 31. Therefore, the problem of cracks occurring in the fine-grained asphalt concrete 6 is eliminated.
