Description

避難所的門構造  Door structure of the shelter  

本發明為關於一種避難所的門構造，係在平時可用作居住空間之避難所的門構造。 The present invention relates to a door structure for a shelter, which is a door structure that can be used as a shelter for a living space.

自平成23年(2011年)3月11日發生東日本大地震以來，各地就頻繁地發生地震，許多專家都認為日本列島已進入地震的活動期。專家並預測在不遠的將來，將在南海海溝發生巨大地震。因此，一定要事先擬定災害時保命的對策。 Since the Great East Japan Earthquake occurred on March 11, 2011 (2011), earthquakes have occurred frequently in various places. Many experts believe that the Japanese archipelago has entered the period of the earthquake. Experts also predict that in the near future, a huge earthquake will occur in the South China Sea Trench. Therefore, it is necessary to formulate countermeasures for life-saving at the time of disaster.

地震所導致的災損，如建築物倒塌等，雖起因於地震本身，但以東日本大地震為例，則是因地震所發生的地震火災、海嘯、海嘯火災而導致災損。 The damage caused by the earthquake, such as the collapse of buildings, was caused by the earthquake itself. However, the Great East Japan Earthquake, for example, was caused by earthquakes, tsunamis, and tsunami fires caused by the earthquake.

當預測會發生海嘯時，自治團體會建議到事先規定的高處設施避難。然而，從地震發生到海嘯來襲的時間非常短，例如預測將發生東海、東南海、南海三連動地震中，有些地區甚至在地震發生後僅5分鐘就有高30m的海嘯來襲。要在如此短暫的時間裡到高處的設施避難，是極為困難的。因此，居住於海岸附近的人們來不及避難，就會面臨被海嘯吞噬的危險。儘管如此，現況是海岸附近幾乎不存在避難所。 When a tsunami is predicted to occur, the autonomous community will recommend taking refuge in a pre-specified high facility. However, the time from the earthquake to the tsunami is very short. For example, it is predicted that there will be three earthquakes in the East China Sea, the Southeast China Sea and the South China Sea. In some areas, even 30 minutes after the earthquake, there will be a 30m high tsunami. It is extremely difficult to take refuge in a high-rise facility in such a short period of time. Therefore, people living near the coast have no time to take refuge, and they are in danger of being swallowed up by the tsunami. Despite this, the current situation is that there are almost no shelters near the coast.

為了提供在上述地震等災害時保命的對策，本發明所提出的避難所，為在平時可當作居住空間使用，在地震時則可當作避難所使用。 In order to provide a measure for life-saving in the event of a disaster such as the above-mentioned earthquake, the refuge proposed by the present invention can be used as a living space in normal times and as a refuge in an earthquake.

在專利文獻1中揭示之避難住宅，為在居住空間內配置避難所。在日常生活中，可有效利用避難所，同時在災害來臨時，居住者不需踏出門外一步，即可在災害發生的當下快速避難。 The refuge house disclosed in Patent Document 1 is a refuge in a living space. In daily life, shelters can be effectively used, and at the same time, when a disaster strikes, occupants do not need to step outside the door to quickly evacuate in the event of a disaster.

在專利文獻2揭示之避難所，為在平時可用作公民館和圖書館等公共設施，當海嘯來襲時，則是可容易漂浮、可確保避難場所之浮體式多人緊急避難所。 The refuge disclosed in Patent Document 2 is a public facility such as a public hall or a library, and when it is hit by a tsunami, it is a floating multi-person emergency refuge that can be easily floated and can secure an evacuation place.

在專利文獻3揭示的門，為可在平時生活使用的個人住宅，同時當海嘯來襲時，可作為供人們避難的避難所之海嘯對策用門。具體而言，是一種透過門推壓機構，將開口部周邊的壁面加以密封之拉門式的門。 The door disclosed in the patent document 3 is a personal residence that can be used in a normal life, and when the tsunami strikes, it can be used as a tsunami countermeasure for a shelter for people to evacuate. Specifically, it is a sliding door type that seals the wall surface around the opening by a door pressing mechanism.

為解決上述課題，然而，在專利文獻1中並未揭示門構造之具體構造。在專利文獻2中所揭示之發明，其通行至外部的入口，為水密門和氣密門的雙重構造，水密門的使用樣態為常時開放狀態。水密門具有重量，在開關時需要耗費大量力氣。上述使用樣態在地震來臨時，有重量的水密門的鉸鏈可能會破損，無法發揮水密門的機能。在專利文獻3所揭示的門構造，其機構相當複雜，且無法降低成本。 In order to solve the above problem, Patent Document 1 does not disclose a specific structure of the door structure. In the invention disclosed in Patent Document 2, the inlet to the outside is a double structure of a watertight door and an airtight door, and the use state of the watertight door is a normally open state. Watertight doors have weight and require a lot of effort when switching. In the above-mentioned use form, when the earthquake comes, the hinge of the watertight door with weight may be damaged, and the function of the watertight door cannot be exerted. In the door structure disclosed in Patent Document 3, the mechanism is quite complicated and the cost cannot be reduced.

用來往來居住空間和本體2內部的開口部103，為設於本體2。開口部103的下端，位於與地板107及樓梯轉角106相同的高度。 The opening 103 for accessing the living space and the inside of the body 2 is provided in the body 2. The lower end of the opening portion 103 is located at the same height as the floor 107 and the stair corner 106.

內門3為用來開關開口部103，為具有沿著曲面2a形狀的懸吊門構造的拉門。在此的曲面2a，為本體2壁面形狀的圓形。內門3為將曲面板的表板30(例如板厚為3mm)和裏板31(例如板厚為9mm)間隔固定距離配置，於上述間隙連續配置數個C型鋼材32(例如板厚為3mm)。也可用中空管取代C型鋼材32。在此的中空管為鋼製管，具體來說，指單管、構造用鋼管、角管。另外，於C型鋼材32之間設楔子，更加提高強度。 The inner door 3 is a sliding door for opening and closing the opening portion 103 and having a suspended door structure having a shape along the curved surface 2a. The curved surface 2a here is a circular shape of the wall surface of the body 2. The inner door 3 is disposed such that the front plate 30 of the curved panel (for example, the plate thickness is 3 mm) and the inner plate 31 (for example, the plate thickness is 9 mm) are disposed at a fixed distance, and a plurality of C-shaped steel materials 32 are continuously disposed in the gap (for example, the plate thickness is 3mm). The C-shaped steel material 32 can also be replaced by a hollow tube. The hollow pipe here is a steel pipe, and specifically refers to a single pipe, a steel pipe for construction, and a corner pipe. Further, a wedge is provided between the C-shaped steel materials 32 to further increase the strength.

於表板30外面設置玻璃綿板33。於玻璃綿板外側，將用來固定的鋼線34設成十字，鋼線是金屬製，例如不鏽鋼製。這樣即可提高內門的隔熱效果，在火災時可抑制本體2內的溫度上昇。(參照圖6) A glass wool sheet 33 is provided outside the front panel 30. On the outside of the glass wool board, the steel wire 34 for fixing is set as a cross, and the steel wire is made of metal, for example, made of stainless steel. In this way, the heat insulation effect of the inner door can be improved, and the temperature rise in the body 2 can be suppressed in the event of a fire. (Refer to Figure 6)

如圖4所示，軌道支撐裝置93，固定於內門3上方的壁面。於軌道支撐裝置93內部設有一對懸垂軌道90、90(以下簡稱懸 垂軌道90)，另於內門3下方，第1軌道9沿著曲面2a設置，一對滾輪90a、90a(以下稱滾輪90a)，滑行於懸垂軌道90上，鐵球9a滑行於第1軌道9上。 As shown in FIG. 4, the rail supporting device 93 is fixed to the wall surface above the inner door 3. A pair of suspension rails 90, 90 (hereinafter referred to as "suspended rails 90") are disposed inside the rail support device 93, and below the inner door 3, the first rails 9 are disposed along the curved surface 2a, and a pair of rollers 90a, 90a (hereinafter referred to as rollers 90a) ), sliding on the hanging rail 90, and the iron ball 9a slides on the first rail 9.

軌道支撐裝置93為剖面觀視時呈矩形的筒狀構造，於底部的中央部形成狹縫，數個鉤子95在貫通此狹縫的狀態下，***軌道支撐裝置93的內部。 The rail supporting device 93 has a rectangular tubular structure in a cross-sectional view, and a slit is formed in a central portion of the bottom portion, and a plurality of hooks 95 are inserted into the rail supporting device 93 while passing through the slit.

T字形的鉤子95為用來垂吊內門3，滾輪90a以可旋轉的狀態安裝於前端部。數個滾輪90a在滑行於懸垂軌道90上的同時，數個鐵球9a滑行於第1軌道9上，這樣一來，內門3就會沿著曲面圓滑地移動。內門3介由數個旋轉體，受懸垂軌道90、第1軌道9支撐，因此分散承受內門3所產生的地震力，即可避免從軌道逸脫。 The T-shaped hook 95 is for hanging the inner door 3, and the roller 90a is attached to the front end portion in a rotatable state. While the plurality of rollers 90a are slid on the suspension rail 90, a plurality of iron balls 9a are slid on the first rail 9, so that the inner door 3 smoothly moves along the curved surface. The inner door 3 is supported by the suspension rail 90 and the first rail 9 via a plurality of rotating bodies, so that the seismic force generated by the inner door 3 is dispersed and the escape from the rail can be avoided.

如圖4、5所示，剖面觀視呈ㄈ字形的溝槽金屬零件108a，為沿著本體2壁面設於內門3的下方。溝槽108(第1凹部)，意指溝槽金屬零件108a所形成的凹部，用來限制內門3因地震力而朝面外方向移動。第1軌道9，自樓梯轉角106鋪設於位於規定深度(例示為20cm)的溝槽108底部。內門3為自鉤子95垂吊的狀態，因此為容易朝面外方向撓曲的構造。當內門3的門面因地震力而朝面外方向變形，內門3會接觸溝槽108的壁面。這樣一來，即可限制內門3朝面外方向變形。 As shown in FIGS. 4 and 5, the grooved metal part 108a having a U-shaped cross section is disposed below the inner door 3 along the wall surface of the body 2. The groove 108 (first recess) means a recess formed by the grooved metal part 108a for restricting the inner door 3 from moving in the out-of-plane direction due to the seismic force. The first track 9, is laid from the corner of the stair 106 at the bottom of the groove 108 at a predetermined depth (illustrated as 20 cm). Since the inner door 3 is in a state of being suspended from the hook 95, it is a structure that is easily deflected in the out-of-plane direction. When the facade of the inner door 3 is deformed in the out-of-plane direction due to the seismic force, the inner door 3 contacts the wall surface of the groove 108. In this way, the inner door 3 can be restricted from being deformed in the out-of-plane direction.

第1軌道9，透過使設於內門3下部的數個鐵球9a旋轉，使內門3圓滑地滑行，鋪設於溝槽108的底面。如上所述，於地震中，以溝槽108限制內門3的變形，即可避免鐵球9a自第1軌道逸脫。 The first rail 9 is rotated by a plurality of iron balls 9a provided at the lower portion of the inner door 3, and the inner door 3 is smoothly slid and laid on the bottom surface of the groove 108. As described above, in the earthquake, the deformation of the inner door 3 is restricted by the groove 108, so that the iron ball 9a can be prevented from escaping from the first track.

又，溝槽108所形成的凹處，最好先以可裝卸的板子塞住。這樣一來，平時就不會妨礙行走，即可安全地往來本體2的內部與居住空間，在地震中，取下板子即可關閉內門3。 Further, the recess formed by the groove 108 is preferably first plugged with a removable plate. In this way, the interior of the main body 2 and the living space can be safely transported without hindering the walking. In the earthquake, the inner door 3 can be closed by removing the board.

門收容部4為在限制支撐內門3的狀態下加以收容，如圖1及圖4所示，於本體2內部沿曲面2a設置。於平時，將內門3以受門收容部4限制支撐的狀態收容，因此不需開關內門3，即可輕易地來往本體2內部和外部。另外，在地震時，當內門3因地震力而朝面外方向變形，內門3的門面幾乎整體都會接觸門收容部4。這樣一來，將內門3所產生的應力由門收容部4分擔。結果不但防止內門3的破損，同時也可避免自第1軌道逸脫。也就是說，門收容部4於地震時，可藉由限制內門3的變形，提高安全性。 The door accommodating portion 4 is housed in a state in which the support inner door 3 is restricted, and is provided inside the main body 2 along the curved surface 2a as shown in FIGS. 1 and 4 . In the normal state, the inner door 3 is housed in a state restricted by the door accommodating portion 4, so that the inner door 3 can be easily accessed to the inside and the outside of the body 2 without opening and closing the inner door 3. Further, at the time of an earthquake, when the inner door 3 is deformed in the out-of-plane direction due to the earthquake force, the door of the inner door 3 almost entirely contacts the door accommodating portion 4. In this way, the stress generated by the inner door 3 is shared by the door accommodating portion 4. As a result, not only the damage of the inner door 3 but also the escape from the first track can be avoided. That is to say, the door accommodating portion 4 can improve the safety by restricting the deformation of the inner door 3 during an earthquake.

第1門框5，為當在閉鎖內門3和外門7時，用來固定上述兩道門，形成開口部103的外緣形狀，為矩形的骨架構造。這樣一來，即可形成面對地震力也難以變形、堅固的開口部103。第1門框5的下端部，位於地板107的下方。也就是說，位於地板107上方的ㄈ字形骨架部分，為可觀視辨認的狀態。另外，墊圈35(封止材)為於本體2的內部側第1門框面，沿著外周部形成環狀雙重構造。 The first door frame 5 is a skeleton structure in which the outer door shape of the opening portion 103 is formed by fixing the two doors when the inner door 3 and the outer door 7 are closed. In this way, it is possible to form the opening portion 103 which is hard to be deformed and strong in the face of the seismic force. The lower end portion of the first door frame 5 is located below the floor 107. That is to say, the U-shaped skeleton portion located above the floor 107 is in a state of being recognizable. Further, the washer 35 (sealing material) is a first door frame surface on the inner side of the main body 2, and has an annular double structure along the outer peripheral portion.

於上層的樓梯轉角(省略圖示)下面，垂吊伸縮棒6，可使內門3緊密貼合第1門框5。使用來垂吊伸縮棒6的線材(省略圖示)，和捲繞線材的旋轉具(省略圖示)連動，即可使伸縮棒6上昇及下降。伸縮棒6具有棒體61、起重裝置62和受力金屬零件13a、b。受力金屬零件13a為安裝於棒體61的一端，受力金屬零件13b為介由起重裝 置62安裝於棒體61的另一端。受力金屬零件13a形成與圓柱形狀的中心軸105緊密貼合的形狀，受力金屬零件13b形成與內門3緊密貼合的形狀。 Below the stair corner (not shown) of the upper floor, the telescopic rod 6 is suspended to allow the inner door 3 to closely fit the first door frame 5. The wire (not shown) for hanging the telescopic rod 6 is used, and the telescopic rod 6 can be raised and lowered in conjunction with a rotating tool (not shown) for winding the wire. The telescopic rod 6 has a rod body 61, a lifting device 62, and stressed metal parts 13a, b. The stressed metal part 13a is attached to one end of the rod 61, and the stressed metal part 13b is attached to the other end of the rod 61 via the lifting device 62. The force-receiving metal part 13a has a shape that closely fits the cylindrical center axis 105, and the force-receiving metal part 13b has a shape that closely fits the inner door 3.

以下說明伸縮棒6的使用。於平時，伸縮棒垂吊於上層樓梯轉角的下面，地震發生後，關閉外門7及內門3，至本體2內部避難。下降伸縮棒6，將受力金屬零件13a與中心軸105緊密貼合，旋轉起重裝置62，將受力金屬零件13b推壓至內門3。這樣一來，內門3介由墊圈35緊密貼合於第1門框5，因此本體2的內部具備高氣密性，因海嘯和海嘯火災而起的海水或毒氣不會流入內部。拉門構造的門，比開關式的門更容易開關，對地震承重的負重性能相當優異，但相對的封閉性能差。但是如本實施型態1將內門3設計為懸吊門構造的拉門，自內部推壓伸縮棒6，即可提高封閉性能。 The use of the telescopic rod 6 will be described below. In the normal time, the telescopic rod is suspended below the corner of the upper staircase. After the earthquake occurs, the outer door 7 and the inner door 3 are closed to evacuate the inside of the body 2. The telescopic rod 6 is lowered, and the stressed metal part 13a is closely attached to the center shaft 105, and the lifting device 62 is rotated to press the force receiving metal part 13b to the inner door 3. In this way, since the inner door 3 is closely attached to the first door frame 5 via the gasket 35, the inside of the main body 2 is highly airtight, and seawater or poison gas from the tsunami and tsunami fire does not flow into the inside. The door constructed by the sliding door is easier to switch than the switch type door, and the load-bearing performance of the earthquake-bearing load is quite excellent, but the relative sealing performance is poor. However, as in the present embodiment 1, the inner door 3 is designed as a sliding door having a suspension door structure, and the telescopic rod 6 is pushed from the inside to improve the sealing performance.

又，在本實施型態中，雖僅具備1根伸縮棒6，但亦可具備數根。另外，受力金屬零件13b以朝曲面2a的圓周方向越長越好，這樣一來，即可介由第1門框5平均地推壓內門3。 Further, in the present embodiment, only one telescopic rod 6 is provided, but a plurality of the telescopic rods 6 may be provided. Further, the force-receiving metal part 13b is preferably as long as the circumferential direction of the curved surface 2a, so that the inner door 3 can be uniformly pressed by the first door frame 5.

如圖1所示，外門7為介由鉸鏈7a，以可朝箭頭V1方向回動的方式固定於第1門框5。如圖3所示，外門7在開啟的狀態下，將鎖金屬零件70朝箭頭V2方向旋轉，以受第2門框8限制支撐。這樣一來，在地震中，對外門7作用的地震力，不只由鉸鏈7a承受，亦可分別分散至鉸鏈7a、鎖金屬零件70，以及第2門框8。結果可避免構造上的弱點、也就是鉸鏈7a的損壞。 As shown in FIG. 1, the outer door 7 is fixed to the first door frame 5 via a hinge 7a so as to be reversible in the direction of the arrow V1. As shown in FIG. 3, in the open state, the outer door 7 rotates the lock metal part 70 in the direction of the arrow V2 to be supported by the second door frame 8. As a result, in the earthquake, the seismic force acting on the external door 7 is not only received by the hinge 7a, but also distributed to the hinge 7a, the lock metal part 70, and the second door frame 8, respectively. As a result, the structural weakness, that is, the damage of the hinge 7a can be avoided.

鎖金屬零件70，用來將外門7限制支撐於第1門框5或第 2門框8，如圖8所示，由在兩端部突出的狀態下，以可回動的方式所固定的軸部70a，自軸部70a兩端垂直延伸的旋轉部70b、c，以及自旋轉部70b朝下方延伸的旋轉部70d所構成。在開啟外門7的狀態下，將旋轉部70b、d朝箭頭V2方向旋轉，旋轉部70c被嵌插於第2門框8所形成的鎖凹部8a。這樣一來，外門7即受第2門框8限制支撐。同樣的，在地震時，於關閉外門7的狀態下，自本體2的內部側旋轉旋轉部70b或70d，這樣一來，外門7即受第1門框5限制支撐。又，在本實施型態中，是以1個鎖金屬零件將外門7限制支撐於第1或第2門框，但也可以用數個鎖金屬零件70限制支撐。這樣一來，可更加分散作用於外門7的地震力。另外，在此雖是使用鎖金屬零件70將外門7限制支撐於第1門框5或第2門框8，但不限於此，亦可用凸輪鎖構造的金屬零件。 The lock metal member 70 is for restraining the outer door 7 from being supported by the first door frame 5 or the second door frame 8, and as shown in FIG. 8, the shaft fixed in a reversible manner in a state of being protruded at both end portions The portion 70a is constituted by the rotating portions 70b and c extending perpendicularly from both ends of the shaft portion 70a, and the rotating portion 70d extending downward from the rotating portion 70b. In a state where the outer door 7 is opened, the rotating portions 70b and d are rotated in the direction of the arrow V2, and the rotating portion 70c is fitted into the lock recess 8a formed by the second door frame 8. In this way, the outer door 7 is supported by the second door frame 8. Similarly, in the state of the earthquake, the rotating portion 70b or 70d is rotated from the inner side of the body 2 in a state where the outer door 7 is closed, so that the outer door 7 is restrictedly supported by the first door frame 5. Further, in the present embodiment, the outer door 7 is restrained and supported by the first or second door frame by one metal lock member, but the support may be restricted by the plurality of lock metal members 70. In this way, the seismic force acting on the outer door 7 can be more dispersed. Here, although the outer door 7 is restricted and supported by the first door frame 5 or the second door frame 8 by using the lock metal member 70, the present invention is not limited thereto, and a metal member having a cam lock structure may be used.

外門7為平板的矩形形狀，其構造與內門3幾乎相同，因此省略說明。又，外門7比第1門框5的內尺寸規定更大為佳。這樣一來，即可提高耐火性能。 The outer door 7 has a rectangular shape of a flat plate, and its structure is almost the same as that of the inner door 3, and thus the description thereof will be omitted. Further, it is preferable that the outer door 7 is larger than the inner size of the first door frame 5. In this way, the fire resistance can be improved.

第2門框8，為矩形的骨架構造，與第1門框5垂直，配置於本體2的外部。第2門框8的下端部，位於地板107的下方。也就是說，形成僅有位於地板107上方的ㄈ字形骨架部分為可觀視辨認的狀態。於自地板107起規定高度(例示為200cm)上，自地板107起規定深度(例示為10cm)的位置，依規定角度(例如直角)配置。 The second door frame 8 has a rectangular skeleton structure and is disposed perpendicular to the first door frame 5 and disposed outside the main body 2. The lower end portion of the second door frame 8 is located below the floor 107. That is, it is formed that only the U-shaped skeleton portion located above the floor 107 is in a state of being recognizable. At a predetermined height (illustrated as 200 cm) from the floor 107, a predetermined depth (illustrated as 10 cm) from the floor 107 is arranged at a predetermined angle (for example, a right angle).

內門3及外門7，平時可在開啟的狀態下使用。這是因為因地震力而損壞的可能性低。這樣一來，不需開關門，即可自由往來於居住 空間和具有樓梯的本體2內部。 The inner door 3 and the outer door 7 can be used in an open state at ordinary times. This is because the possibility of damage due to seismic force is low. In this way, the door can be freely moved to and from the living space and the interior of the body 2 having the stairs without opening and closing the door.

以下參照圖9、圖10說明本實施型態2的避難所門構造201(以下簡稱門構造201。)。本實施型態2與實施型態1基本上共通，因此零件編號以200起始，援用圖示和說明，主要說明兩者差異。 Next, the refuge door structure 201 of the present embodiment 2 (hereinafter referred to as the door structure 201) will be described with reference to Figs. 9 and 10 . This embodiment 2 is basically the same as the embodiment 1, so the part number starts with 200, and the illustration and description are used to explain the difference between the two.

如圖9、圖10所示，第2實施型態與第1實施型態的差異為，設於本體202的外門207，為曲面形狀的拉門。該外門207與內門3的構造相同。具體來說，依規定間隔配置形成曲面板的表板230(例示為板厚3mm)和裏板231(例示為板厚9mm)，於上述板的間隙連續配置數個C型鋼材232(例示為板厚3mm)。於C型鋼材232之間設有楔子238，更加增加強度。 As shown in FIGS. 9 and 10, the difference between the second embodiment and the first embodiment is that the outer door 207 of the main body 202 is a curved door. The outer door 207 has the same configuration as the inner door 3. Specifically, a watch plate 230 (illustrated as a plate thickness of 3 mm) and a back plate 231 (illustrated as a plate thickness of 9 mm) forming a curved panel are disposed at predetermined intervals, and a plurality of C-shaped steel materials 232 are continuously disposed in the gap of the plate (illustrated as Plate thickness 3mm). A wedge 238 is provided between the C-shaped steel materials 232 to further increase the strength.

對應內門203和外門207，與第1實施型態的門收容部4相同構造的門收容部204，和周設於該門收容部204外側的門收容部271雙重設置。與第1實施型態的第1軌道9相同構造的第1軌道209，和周設於該第1軌道209外側的第2軌道259雙重設置。 Corresponding to the inner door 203 and the outer door 207, the door accommodating portion 204 having the same structure as the door accommodating portion 4 of the first embodiment is provided in a double arrangement with the door accommodating portion 271 provided on the outer side of the door accommodating portion 204. The first rail 209 having the same structure as the first rail 9 of the first embodiment is provided in a double arrangement with the second rail 259 provided on the outer side of the first rail 209.

第1軌道209和第2軌道259，鋪設於與第1實施型態的溝槽108相同的溝槽(第2凹部，省略圖示)的底面。 The first rail 209 and the second rail 259 are laid on the bottom surface of the groove (the second recess, not shown) which is the same as the groove 108 of the first embodiment.

內門203及外門207，平時可於開啟的狀態下使用，這是因為因地震力而損壞的可能性低。這樣一來，不需開關門，即可自由往來於居住空間和有樓梯的本體202內部。又，與第1實施型態相同，先以使用可裝卸的板子塞住凹處為佳。 The inner door 203 and the outer door 207 can be normally used in an open state because the possibility of damage due to seismic force is low. In this way, the door 202 can be freely moved to and from the living space and the body 202 having the stairs without opening and closing the door. Further, in the same manner as in the first embodiment, it is preferable to first use a detachable plate to close the recess.

使伸縮棒206對應海嘯波壓適當地伸長，通貫內門203的內壁、中心軸205或中心軸205，設置於與本體202內壁之間。 於內門203、外門207設置緊急避難口291，可裝卸蓋子。 The telescopic rod 206 is appropriately elongated corresponding to the tsunami wave pressure, and is disposed between the inner wall of the inner door 203, the center shaft 205, or the center shaft 205, and is disposed between the inner wall of the body 202. An emergency evacuation port 291 is provided in the inner door 203 and the outer door 207 to attach and detach the cover.

本發明為設置於居住空間內的避難所的門構造，可以低價、自由地使用，且安全性高，產業利用可能性相當大。 The present invention is a door structure of a shelter installed in a living space, and can be used at low cost and freely, and has high safety and considerable industrial utilization possibilities.
