Description

  The present invention can be used mainly as an exterior part of a building, particularly as a door for a doorway, so that even when the door cannot be opened due to a natural disaster or the like, it is possible to evacuate by opening a part of the door. Concerning building doors.

  In emergency evacuation during natural disasters such as typhoons, earthquakes, floods, and tsunamis, there are not a few cases where sliding doors and doors do not open due to wind pressure, water pressure, and building errors. In particular, when such a situation occurs at the entrance of a building, it becomes a serious problem related to human life such as an unexpected delay in escape.

  Conventionally, as a precaution for evacuation in preparation for a disaster, priority is given to first securing the evacuation route by opening the entrance door next to cleaning up the fire. However, evacuation knowledge in the event of a disaster by securing the evacuation route by opening the entrance door is considered appropriate for earthquake disasters, but it is not necessarily an appropriate measure for disasters other than earthquakes. In many cases, it is a measure that contains the danger of increasing or aggravating disaster damage. That is, in an earthquake disaster, it can be caused by intense vibration applied to a building. For example, there is a very high probability that the entrance door will not open due to deformation or damage to the door frame of the entrance door, or incorrect installation, so open the entrance door in advance and secure an evacuation passage before the entrance door stops opening There is a need. However, it is necessary to prevent the intrusion of hot wind and flames in the case of a fire other than an earthquake, for example, in the vicinity of a fire. In the event of a typhoon disaster, it is necessary to prevent the invasion of storms. In any case, it is necessary to keep the entrance door closed. However, how to secure an evacuation route when the entrance door is not opened due to wind pressure, water pressure, or debris flow in response to avoiding damage or minimizing damage by closing the entrance door Is a problem.

Japanese Utility Model Publication No. 7-21928 JP 2005-314952 A JP 2011-163085 A

  To prevent the door from opening in the event of a disaster, for example, adopt a configuration that incorporates an evacuation door in the upper half of a normal vertical and horizontal door plate, and close the door body to prevent debris flow and flood intrusion. There is a proposal that enables escape through an escape door and guidance for escape while preventing it (see Patent Document 1 above). In addition, an intrusion prevention plate such as a debris flow is attached to the lower half of the door plate shown in the same document, and this portion is configured so that the thickness of the door doubles.

  In addition, to solve the same problem, the door plate has a two-stage structure with an upper door portion and a lower door portion, and can be released with the lower end of the upper door portion and the upper end of the lower door portion abutted against each other. There is a proposed example in which connecting means for connecting and child lock means for releasably positioning the lower door portion in the closed position are provided (see Patent Document 2).

  In the above proposal, only the upper door portion can be opened and closed with the lower door portion closed.

  The technique shown in this proposal is intended to ensure the safety of infants who do not have the discriminating ability, and is not intended to ensure a condemned route in the event of a disaster. However, since the configuration is similar to the configuration of the present invention described later, it is posted in the same column for reference.

  Here, the present inventors' view about the building which is the attachment object of a door is shown. The building is a durable facility for safely partitioning a human living space from the outside world, and is a collection of various components. The division from the outside world is intended to block wind and rain and heat transfer, and various components constituting the building are combined with elaborate processing and ingenuity to achieve such purpose. The applicant of the present application has also filed a patent application according to Patent Document 3.

  For example, for the propagation of heat and sound, the heat treatment and sound are filled with the insulation material within the wall thickness, and for the blowing of wind and rain, the outer wall panel The caulking process of the butt part, the sealing process of the peripheral part of the glass, the installation of eaves around the door frame, the use of a rain draining structure, the rain return structure, and the installation of rain closing equipment such as rain gutters etc. Is mentioned.

  Doors installed in buildings belong to the technical field of joinery, which is different from the technical field of buildings. However, a door built in a building, especially a door around the outside of the building, is bound to the same purpose as the building body as a part of the building. This is because if the door has a low shielding performance from the outside world, the entire building to which the door is attached must have a low shielding performance from the outside world.

  As described above, referring to the conventional example described above in view of the same kind of required performance as that for the building body, the door built in the building, The proposal that employs a configuration in which a smaller evacuation door is incorporated in the half part independently (above, Patent Document 1) can achieve the purpose of securing a condemned route at the time of a disaster.

  However, since the door for blame is small in size, even if it is possible to omit the amount of members, as long as it is a door, it is not possible to omit items such as hinge brackets, handles, and other attached members The required performance for the door must be satisfied twice for the door body and the slammed door.

  In other words, the blame door attached to the door is also required to have reliable wind and rain blocking functions, disaster prevention, and crime prevention functions. As a result, this results in another problem that a doubling of the manufacturing process, the number of used members, and the manufacturing cost cannot be avoided. Further, regarding the durability performance required for the door main body, any of bending rigidity, torsional rigidity, and panel rigidity in the longitudinal direction and the width direction of the entire door plate must be lowered. This is because the blame door and the door body cannot be rigidly joined because the blame door must be opened and closed independently.

  Furthermore, when a door having such a configuration is used for entrance purposes, it is considered necessary for crime prevention to require a special device that does not give a sense of incongruity visually.

  Next, Patent Document 3 may take time when the emergency opening / closing member is removed, and may not be able to smoothly open and close during an emergency disaster. Moreover, although it can say to any of patent documents 1-3, even when not using an emergency opening / closing member, when opening an emergency opening / closing member for ventilation etc., opening and closing work is simple and reliable. Although it is required to do so, it cannot be said that it can respond to such a request.

  Next, the door plate has a top and bottom two-stage configuration of an upper door portion and a lower door portion, and an upper and lower divided door that enables opening / closing operation of only the upper door portion in a state where the lower door portion is closed (see Patent Document 2 above). ) Can sufficiently contribute to securing a condemned route in the event of a disaster because the entire upper door portion opens largely like a normal door regardless of the intended purpose of the above proposal. Moreover, regarding the external force applied to the door plate, it is considered that the upper door portion and the lower door portion can receive the external force as independent door plates, and thus it is considered that sufficient durability performance is exhibited.

  However, when adopting a configuration in which the door plate is divided into the upper door portion and the lower door portion as described above, the following problems occur. This problem is caused by the fact that the divided upper door portion and lower door portion cannot be made into a completely intimate structure.

  That is, when only the upper door part is opened and closed while the divided upper door part and lower door part are in close contact with each other, the lower end surface of the upper door part and the upper end face of the lower door part inevitably buffer in the direction of displacement. As a result, not only a smooth opening / closing operation of the upper door portion cannot be ensured, but also the assembly structure of the lower end portion of the upper door portion and the upper end portion of the lower door portion is destroyed by repeated forcible opening / closing operations. That is, when adopting a configuration in which the door plate is divided into upper and lower parts, it is necessary to set an appropriate operation clearance between both the upper and lower door portions for opening and closing operations.

  However, when an operation clearance is set between the upper and lower door parts, the function to prevent the blowing of wind and rain that the door should have is greatly reduced, and the upper and lower door parts are connected. Therefore, it is necessary to secure the connection when operating as a single door plate depending on some connection metal fittings. As the connection metal fitting assumed to be suitable for the connection and separation of the two members located above and below the door as the object, as introduced in the above-mentioned Patent Document 2, "round drop" and "France drop" It can be said that a lock fitting called "" is an industry standard.

  The structure of the lock fitting called “round drop” is described in detail in 2 in the above-mentioned patent document. To sum up this, it can be said that it is designed to operate in the vertical direction. You can say that. This is the same for “French drop”. Moreover, although it seems that it can be easily experienced by actually operating the fittings using these lock fittings, it is characterized in that a locked door or the like is loose in a locked state.

  The looseness in fittings using "round drop" or "France drop" is an inevitable structure of these lock fittings. If there is no looseness, it will be extremely difficult to lock. It becomes. This means that when the divided upper and lower door parts are connected only depending on “round drop” or “France drop”, the side door part that is not directly operated is loose. Is inevitable. However, no other suitable locking mechanism seems to be provided for joinery-related connections and separable vertical connection applications. Such a lack of unity between the upper door part and the lower door part causes abnormal noise from the door plate closed in the event of wind and rain, and causes a sense of incongruity when operating as an integrated object. appear.

  Therefore, an object of the present invention is to enable simple and reliable opening and closing operations by the same operation in an emergency as well as a normal opening and closing operation, and from the viewpoint of crime prevention, manufacturing and design, from a conventional building door. The goal is to provide a building door with a design that is no different. In addition, by setting an appropriate operating clearance between the upper and lower door plates, smoothness when opening and closing only one of the door plates is ensured, and when the required operating clearance is set, the operating clearance is set. It is possible to reliably block the blowing of wind and rain from the door, and in the case of operating as a normal door plate, it is possible to realize a reliable integration of the door plate in a state of being divided vertically The purpose is to provide a building door that can.

The building door of the present invention is a building door in which an opening having a size that allows a person to escape when the door plate is closed is formed, and an emergency opening / closing member is incorporated in the opening. The door plate includes a door plate that is an emergency opening / closing member that can be freely opened and closed on the door frame, a door plate that can be freely opened and closed on the door frame, and a connection release unit that can connect and release these door plates. It is characterized by that.
According to the present invention, if the door plates are connected by the connection release means, the opening and closing operation can be performed simultaneously, and if the door plates are released by the connection release means, the door plates are separately opened. be able to.

According to the present invention, the emergency opening / closing member is opened and closed by using a door knob as an operating portion, and the door knob for opening and closing the door plate also serves as the door knob of the emergency opening / closing member.
Further, the present invention includes a lock mechanism having a door knob that opens and closes a door plate of a building as an operation portion, and the lock mechanism also serves as a lock mechanism having the door knob of the emergency opening and closing member as an operation portion. It is characterized by.
According to the present invention, since it is not necessary to provide a door knob separately from the door knob of the emergency opening / closing member, the door knob is normally used as a door knob of a building door, and in the event of an emergency disaster, the same door knob is used to Opening and closing operation is possible. Therefore, it is not necessary to prepare two door knobs or a lock mechanism for manufacturing convenience, and also has a crime prevention effect.
According to the present invention, the door plate includes an upper door plate that is an emergency opening and closing member that can be freely opened and closed on the door frame, a lower door plate that can be opened and closed on the door frame, the lower door plate, The door plate includes a latch lock mechanism that uses the door knob as an operating portion, and the latch lock mechanism is connected to the upper door together with the door knob. It is attached to a board. The above solution means a configuration for realizing the shut-off state of the upper door plate and the lower door plate provided independently and ensuring the adhesion to the door frame with a single latch lock mechanism.

  In addition to the locking device, the door of the building requires a latch lock mechanism for maintaining the closed state of the door plate. The latch lock mechanism not only simply maintains the door plate in the cut-off state, but also has a function of pressing the door plate against the door frame to maintain an airtight state. Moreover, the latch lock mechanism in the door of a building usually uses a door knob as an operation part for the convenience of operation.

  When the door plate is composed of an independent upper door plate and a lower door plate as in the building door of the present invention, it is possible to maintain the upper and lower door plates in a closed state with one latch lock mechanism and to the door frame. It is usually difficult to energize to ensure adhesion. However, in the door of the building of the present invention, since the upper door plate and the lower door plate in a state of being connected via the connection release means as described above are highly integrated, the upper door plate is pressed against the door frame. Thus, the urging force for urging can be transmitted almost directly to the lower door plate via the rain drain plate and the rain return plate. As a result, the action of the latch lock mechanism for the upper door plate can be directly applied to the lower door plate.

  According to the present invention, the door plate includes an upper door plate that is an emergency opening and closing member that can be freely opened and closed on the door frame, a lower door plate that can be opened and closed on the door frame, the lower door plate, Connection release means for aligning and separating the upper door plate in a separable manner, and providing either one of the upper door plate and the lower door plate or an inner key that can be operated keylessly only from the indoor side It is characterized by. The above solution means a preferable option of the locking part when locking the door plate in the closed state. That is, when the building door is a door for outward rotation of the building, it can be said that it is self-evident in terms of crime prevention to provide an outer key that performs a locking operation and an unlocking operation using a key. However, as in the present invention, normally, when the door plate that is an integral body is separated into the upper door plate and the lower door plate, the locking mechanism can be operated without a key only from the indoor side. The problem arises as to which door plate should be provided with a so-called inner key.

For the selective problem, it is effective to provide a so-called inner key on the upper door plate. In the door plate of the present invention, the rain plate in a mode that hangs down from the upper door plate overlaps with the outdoor side panel surface of the lower door plate, so that the lower side of the upper door plate is locked by the inner key. This is because the structure inevitably ensures that the door plate cannot be opened.
It is also effective to provide the inner key on the lower door plate. The reason for this is, for example, when the opening / closing failure occurring in the lower door plate is a variable opening / closing failure such as wave dragging, and the upper door plate is left open and the lower door plate is This is because it can be prevented from being pulled open by a pulling wave. Furthermore, it is also effective to provide so-called inner keys on both the upper door plate and the lower door plate because, in addition to the above, redundancy of locking or a crime prevention effect due to unexpectedness can be expected.

  As the door of the building of the present invention, the door frame fixed around the door opening of the building can be opened and closed through a plurality of hinge fittings, and the door is centered on the hinge fitting through the door knob. In a door of a building that is opened and closed by turning the plate, the door plate is predetermined between the upper door plate and a panel-like upper door plate that can be opened and closed on the door frame via a hinge fitting. A lower door plate that can be opened and closed on the door frame by setting an operation clearance of the door, and a connection release means that detachably connects the lower door plate and the upper door plate in a straight line. The upper door plate is provided with a rain plate that extends downward at the lower end of the outdoor panel surface, and the lower door plate is provided with a rain return plate that extends upward at the upper end of the indoor panel surface. , The connection release means are the upper door plate and the lower side The upper and lower door plates in a state where the operation clearance set between the door and the door is closed from the outdoor side by a rain-cutting plate and the operation clearance is closed from the indoor side by a rain return plate and aligned. Is locked in that state.

  Here, in the above, “rain draining” means, for example, that raindrops falling on the outer wall surface of the building flow down the outer wall panel surface and invade the seam of the outer wall panel or the seam of the foundation and the foundation. For the purpose of preventing, it means guiding the rainwater flowing down to the side or below of the seam. Therefore, “rain plate” means a plate-like body having such a function. The term “rain return” refers to blocking the path of rain water for the purpose of preventing rain water that has entered the joint between the two members from crossing the joint and flowing down the inner surface of the outer wall panel or the like. Therefore, the “rain return plate” means a plate-like body having a function like a dam plate, for example. In addition, “panel shape” means that the whole is configured as a single plate, is a single member or a multi-member assembly, has irregularities or steps on the surface, material It does not matter what kind of material is used, whether it contains a material such as glass or resin.

  Constituent members included in the above solution are a door plate, a door knob for operating the door plate, and a hinge fitting for building the door plate on the door frame so that the door plate can be turned or turned. The door plate includes an upper door plate and a lower door plate.

  The upper door plate and the lower door plate are independent of each other and can be freely opened and closed on the door frame via hinge fittings. At this time, a predetermined operation clearance is set between the upper door plate and the lower door plate. Details of the location where the operation clearance is set are between the lower end surface of the upper door plate and the upper end surface of the lower door plate. In addition, the upper door plate is provided with a rain plate that extends downward at the lower end of the outdoor panel surface, and the lower door plate is a rain return plate that extends upward at the upper end of the indoor panel surface. Prepare.

  As a result, even in the event of a natural disaster or the like, even if a cause of an open / close trouble occurs on the lower side of the door plate, it is possible to blame by opening only the upper door plate while leaving the lower door plate as it is. At this time, since the operation clearance is set between the upper door plate and the lower door plate, a smooth opening operation of the upper door plate is ensured. There are no problems such as taking time and effort.

  On the other hand, if the open upper door plate is operated in the closing direction, the rain plate in a mode that hangs down from the lower end of the upper door plate overlaps the upper edge of the outdoor side panel surface of the lower door plate. The upper door plate can be closed without requiring an independent operation. At this time, the rain plate of the upper door plate closes the operation clearance set between the two from the outside. At the same time, the same operation is realized on the indoor side of the door plate.

  That is, when the upper door plate is closed, the lower edge of the indoor panel surface of the upper door plate overlaps with the rain return plate extending in the upward direction from the indoor panel surface of the lower door plate. Closes with the upper door plate without requiring an independent operation. At this time, the rain return plate can block the operation clearance set between the two from the indoor side. Further, the connection release means can lock the upper door plate and the lower door plate aligned in this manner in this state.

  Rain water that has fallen on the outdoor side panel surface of the closed door plate falls from the lower end of the rain drain plate along the indoor side panel surface of the upper door plate and cannot enter the operation clearance. Even if it enters into the operation clearance due to the occurrence of an unforeseen situation, the intruded rainwater is prevented from entering the indoor side by the rain return plate of the lower door plate.

  The above-described action by the combination of the rain drain plate and the rain return plate is similarly exerted for wind as a fluid similar to water. In other words, the rain plate and the rain return plate strongly prevent the entry of wind and rain from the operation clearance portion as a double barrier having mutually complementary functions.

  The connection portion between the upper door plate and the lower door plate connected via the connection release means is sandwiched between the rain plate and the rain return plate from both sides. Therefore, the rain plate and the rain return plate not only prevent the entry of wind and rain, but also function to enhance the structural integrity of the two. Preventing the occurrence of

  According to the present invention, since it is not necessary to provide a door knob separately from the door knob of the emergency opening / closing member, the door knob is normally used as a door knob of a building door, and in the event of an emergency disaster, the same door knob is used to Opening and closing operation is possible. Therefore, it is not necessary to prepare two door knobs for manufacturing convenience, and it has a crime prevention effect. In an emergency disaster, the opening / closing operation can be performed smoothly as in the normal opening / closing operation.

  Also, when it is desired to open the emergency opening / closing member for ventilation or the like, the opening / closing operation can be performed easily and reliably. Furthermore, when the upper door plate and the lower door plate are connected via the connection release means, the operation clearance set between them is blocked from the outdoor side and the indoor side by the rain drain plate and the rain return plate. In addition, a structure in which the lower end portion of the upper door plate and the lower end portion of the lower door plate are sandwiched between the inside and outside by the rain drain plate and the rain return plate is realized. There is no room for lowering or rattling, and the same performance as a normal door plate can be achieved with regard to space blocking performance and handling as part of a building.

It is a front view which shows the state applied to the flooding prevention construction method of this invention. It is a top view which shows the state applied to the flooding prevention construction method of this invention.

  Embodiments of the present invention will be described below with reference to the drawings.

  Today's building doors are mainly sash doors made of so-called aluminum sash, which is made by extruding an aluminum alloy and applying alumite surface treatment to it. Therefore, sash doors with substantial demand are illustrated and described in the following embodiments. In order to achieve both weight reduction and mechanical rigidity, the aluminum sash material usually has a very complicated cross-sectional shape. However, since it is not necessary to draw such a complicated cross-sectional shape as it is, it may be difficult to understand the contents of the invention. Therefore, in this embodiment, the cross-sectional shape is omitted. .

  The door of the building of the present invention can be operated in a manner similar to a normal door of a building through a frame-like door frame 10 fixed to the door opening of the building and a plurality of hinge fittings J. And the door plate 20 to be built. The door plate 20 built in the door frame 10 has a natural appearance that is the same as a normal door plate, both in the front view from the outside (FIG. 1) and in the rear view from the room (FIG. 2). is there. The natural appearance is an element that contributes to not inadvertently collecting malicious attention such as thieves.

  The door frame 10 includes a right vertical frame rail 11 and a left vertical frame rail 12 in a front view from the outside, and an upper frame rail 13 that connects the upper ends of the right vertical frame rail 11 and the left vertical frame rail 12 to each other; This is a quadrilateral frame composed of a lower frame crosspiece 14 in which the lower ends are connected to each other.

  The door plate 20 includes an upper door plate 20A that is an emergency opening / closing member and a lower door plate 20B. Both are independent but independent (FIG. 3). In addition, the figure is the perspective view which projected the door board 20 from the indoor side, and the indoor side panel surface PB of 20 A of upper side door plates and the lower side door plate 20B is shown as an upper surface.

  The upper door plate 20A forms a frame-like body by joining the upper and lower ends of a pair of left and right vertical rods 21, 21 with an upper rail 22 and a lower rail 23, respectively. By inserting the plate 27, the whole is formed into a single panel. The pair of left and right vertical rods 21, 21 and the upper rail 22 and the lower rail 23 are rigidly joined, and the upper door plate 20A can maintain its outer shape without depending on the glass plate 27.

  On the lower rail 23 of the upper door plate 20A, there is formed a rain drain plate 24 that extends the outdoor side panel surface PA downward (FIGS. 3 and 4). The full width of the rain plate 24 at this time extends to the full width of the upper door plate 20A. Two hinge fittings J, J arranged at a vertical interval are screwed to one vertical rod 21 of the upper door plate 20A, and the door plate 20 is attached to the lower rail 23 of the upper door plate 20A. A door knob 26 that opens and closes the door, an external key 40 that uses the door knob 26 as an operating portion, and a latch lock mechanism (lock mechanism) 50 are incorporated. Further, a vertical keyhole 3H (FIGS. 3, 5, and 6) is provided on the lower end surface of the vertical rod 21 closest to the door knob 26. FIG.

  The lower door plate 20B forms a frame-like body by joining the upper and lower ends of a pair of left and right vertical rods 21, 21 with an upper rail 22 and a lower rail 23, respectively. By fitting the siding plate 28, the whole is formed into a single panel. The pair of left and right vertical rods 21, 21 and the upper rail 22 and the lower rail 23 are rigidly joined, and the upper door plate 20A can maintain its outer shape without depending on the siding plate 28. However, the siding plate 28 exhibits a great reinforcing effect with respect to maintaining the outer shape of the lower door plate 20B. That is, in the door plate 20, the lower door plate 20B has higher mechanical rigidity as a panel than the upper door plate 20A. This is a countermeasure against the opening and closing troubles in the door of the building being concentrated in the lower half of the door plate 20.

  On the other hand, a rain return plate 25 is formed on the lower rail 23 of the lower door plate 20B so as to extend the indoor side panel surface PA upward. The full width of the rain return plate 25 extends to the full width of the lower door plate 20B. Also for the lower door plate 20B, two hinge fittings J, J are attached to one vertical rod 21, and the connection release means 30 and the inner key 60 are incorporated in the other vertical rod 21.

  The upper door plate 20A and the lower door plate 20B are attached vertically to the right vertical frame bar 11 of the door frame 10 via hinge fittings J and J, respectively, and constitute a so-called left-open door plate 20. (FIG. 1). At this time, between the upper door plate 20A and the lower door plate 20B arranged above and below, more specifically, between the lower rail 23 of the upper door plate 20A and the upper rail 22 of the lower door plate 20B. The operation clearance G is preferably set to about 2 mm to 3 mm (FIGS. 1 and 2). The operation clearance G is set in consideration of the strength of the door frame 10 and the hinge fittings J, the installation accuracy of the upper door plate 20A and the lower door plate 20B, and the like.

  Here, the connection releasing means 30 and the like used in the present invention are generally widely used locking mechanisms. Since the locking mechanism is not reverse engineered by a thief or the like, a highly sophisticated and complicated mechanism is employed, and it is not easy to elucidate the unlocking operation even if the actual thing is disassembled. Therefore, in the connection release means 30 and the like, the structural description is omitted, and only a general usage and a usage in the present invention will be briefly described.

  The outer key 40 and the latch lock mechanism 50 incorporated in the lower rail 23 of the upper door plate 20A are a general attachment mode and are used in a general usage mode. The same applies to the inner key 60 incorporated in the vertical shaft 21 of the lower door plate 20B. However, the connection release means 30 is a usage peculiar to the door plate 20 of the building of the present invention. The connection release means 30 itself is a commercial product, and has a structure in which a slide key 32 called a so-called round drop or a French drop is moved up and down. Further, the connection release means 30 employs a system in which the slide key 32 is moved up and down by reversing the operation lever 31 (FIGS. 2, 3, 5 and 6). This is based on consideration that the connection release means 30 does not operate unintentionally due to vibration such as an earthquake.

  In the arrangement in which the slide key 32 is made to correspond to the key hole 3H formed in the lower end surface of the vertical rod 21 of the upper door plate 20A, the connection release means 30 is the upper end portion on the indoor side of the vertical rod 21 of the lower door plate 20B. (FIGS. 3 and 5).

  The upper door plate 20A and the lower door plate 20B built on the door frame 10 so as to form a single door plate 20 by setting a predetermined operation clearance G are temporarily attached to the door frame 10 alone. If so, it can be freely opened and closed through hinge fittings J and J, respectively. However, in the door plate 20 of the present invention, if the upper door plate 20A is not opened, the lower door plate 20B will not open carelessly, and if the upper door plate 20A is closed, An interlocking relationship is established that the lower door plate 20B is also interlocked and closed. As a result, the occurrence of adverse effects such as a decrease in the crime prevention performance of the lower door plate 20B, inadvertent forgetting to tighten, and a complicated opening / closing operation are suppressed.

  Next, a series of operational relationships when the building door of the present embodiment is actually used will be described.

  The door plate 20 of the building of the present invention is used in the same manner as the normal door plate 20 by connecting the upper door plate 20A and the lower door plate 20B in normal times. At this time, it is the rain plate 24, the rain return plate 25, and the connection release means 30 that are involved in the integration of the upper door plate 20A and the lower door plate 20B.

  Here, when the upper door plate 20A is operated in the closing direction F2 based on the state in which the upper door plate 20A is opened (the state shown in FIG. 6), the rain droops from the outdoor side panel surface PA of the upper door plate 20A. A rain return plate in which the cut plate 24 is buffered so as to overlap the outdoor side panel surface PA of the lower door plate 20B, and the indoor side panel surface PB of the upper door plate 20A rises from the indoor side panel surface PB of the lower door plate 20B. Buffer to overlap 25. At this time, since the operation clearance G is set between the lower end surface of the upper door plate 20A and the upper end surface of the lower door plate 20B, the closing operation of the upper door plate 20A can be executed smoothly.

  The rain-cutting plate 24 and the rain return plate 25 overlap each other on the upper door plate 20A and the lower door plate 20, so that the operating force for operating the upper door plate 20A in the closing direction F2 is applied to the lower door plate 20 as it is. Communicated. Therefore, the upper door plate 20A and the lower door plate 20 are integrally pressed against the door frame 10 and locked at the shut-off position by the automatic operation of the latch lock mechanism 50 (the state shown in FIG. 5).

  For example, the lower door plate 20B locked to the cut-off position is opened independently unless a strong force is applied to the rain plate 24 and the rain return plate 25 from the indoor side. There is no. In addition, it cannot be assumed that such a powerful force acts on the door plate 20 from the indoor side, and it can be said that the necessity for the assumption is poor.

  The upper door plate 20A and the lower door plate 20 locked in the closing position push the slide key 32 upward by performing the reversing operation of raising the operation lever 31 of the connection release means 30 and tilting it to the opposite side. And can be integrated. Thereby, the upper door plate 20 </ b> A and the lower door plate 20 </ b> B can be normally used as the normal door plate 20. In this state, the slide key 32 pushed upward from the lower door plate 20B is inserted into a key hole 3H formed in the upper door plate 20A.

  Further, the connecting portion of the upper door plate 20A and the lower door plate 20B, that is, the portion of the operation clearance G, is sandwiched between the outdoor side and the indoor side by the rain plate 24 and the rain return plate 25, As a result, the single slide key 32 of the connection release means 30 realizes a stable connected state without backlash, a weather resistance performance and sound insulation performance comparable to an integrated door plate, and a natural appearance. The intent of the inventors of the present application has been realized without regret.

Here, the lower door plate 20 </ b> B locked at the closing position can be locked to the door frame 10 by the inner key 60. The operation of the inner key 60 of pushing the slide key 62 to the side and the function of the inner key 60 (FIGS. 2 and 3) are the same as those of the ordinary inner key. Only the upper door plate 20A can be operated in the opening direction F1 in a state where the key 60 is locked (FIG. 6).
That is, the upper door plate 20A and the lower door plate 20B are secured by a simple mechanism using a single slide key 32 of the connection release means 30. In an emergency, a key or complicated operation is required. The upper door plate 20 </ b> A can be freely opened and closed without being restrained by the lower door plate 20.

  In the description of the above embodiment, the present invention is disclosed by exemplifying so-called sash doors. However, as described above, the present invention is not dependent on a material that is difficult to implement unless it is a specific material. There is no security at all, so wooden doors, which are showing a trend of local fashion as entrance doors for suburban houses, are also demanded for buildings for offices and factories. It can also be implemented as a highly functional steel door. Further, the door knob 26 may be a lever type, and can be applied to a lock with a button at the center or a lock with a key hole.

  As another method for ensuring the access of people to the house 20 where the inundation prevention sheet 10 is constructed, a method using the upper entrance protection enclosure 40 or a combination of the door plate 12 and the inundation prevention sheet 10 is used. (Figs. 7 and 8). In the following, a method using the upper entrance protection enclosure 40 will be described, but the flood prevention work can be performed only by the door plate 12 and the flood prevention sheet 10 (FIGS. 7 and 8).

  The entrance protection enclosure 40 includes a pair of side walls 41 and 41 installed at the left and right positions of the entrance opening of the house 20, portal post-shaped guide posts 42 and 42 attached to the inner side surface of the tip of the side walls 41 and 41, and a guide. It can be assembled from an arbitrary number of dam plates 43 fitted into the guide grooves formed in the posts 42, 42 so as to have an appearance like a gate, for example. The material of the side wall 41, the guide post 42, and the barrier plate 43 is not particularly limited. The barrier plate insertion method is a blocking method applied to a sluice for adjusting the water level of a small river, and the height of the upper end can be adjusted depending on the number of barrier plates 42 used.

  The entrance protection enclosure 40 as described above can be used for the purpose of protecting the entrance from the wind and rain exclusively without using the dam plate 42 during normal times. The dam plate 42 is used by inserting a necessary number of left and right guide posts 42 and 42 within a height range in which a person can pass in the event of a heavy rain flood warning or the like. The infiltration prevention sheet 10 regards the entrance protection enclosure 40 as a part of the house 20, and is constructed so as to surround the outside. In this method, since the inundation preventing sheet 10 is not applied to the entrance door 24, the opening / closing operation of the entrance door 24 is not hindered even if the outdoor inundation water level rises to a level that reaches the entrance door 24. Therefore, free access to the house 20 to which the flooding prevention method of the present invention has been applied is ensured while preventing water from entering the house 20.
