Description

[Technical field]

[0001] The present invention relates to a waterproofing device for a PAT door and a method for installing the same. [Background technology]

[0002] Conventional waterproofing measures for existing doors include replacing the door, installing a waterproof plate, improving drainage facilities, etc. These methods can impart waterproofing to existing doors that do not have waterproofing capabilities. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2015-151717 A Summary of the Invention [Problem to be solved by the invention]

[0004] The above-mentioned waterproofing measures require the installation of structures by workers, and because this installation work is large-scale, it takes a long time to implement the waterproofing measures. Also, when waterproofing measures using waterproof rubber are implemented for AT (soundproof door) or PAT (perfectly soundproof door), the tip of the blade installed around the entire perimeter of the door panel is thin, so the area to crush the waterproof rubber is insufficient, and the waterproofing measures may not be sufficient.

[0005] The object of the present invention is to provide a water stopping device for a PAT door, which is easier to install and has a higher water stopping effect than conventional devices, and a method for installing the same. [Means for solving the problem]

[0006] In order to achieve the above object, the waterproofing device for a PAT door according to the present invention comprises a frame body, a door body, and an elastic body. The frame body is provided along an opening that connects the outside and the inside. The door body has a surface facing the inside, a protruding portion provided along the width direction at the lower end of the surface and protruding in a direction substantially perpendicular to the surface, a pillar member fixed to the periphery of the surface, and a first adhesive member provided between the pillar member and the surface and between the protruding portion and the pillar member, and is rotatably connected to the frame body. The elastic body is fixed to the inner periphery of the frame body. When the door body is in a closing position that closes the opening, the elastic body is interposed between the frame body and the protruding portion.

[0007] According to the above-mentioned configuration, it is possible to provide a water stop device for a PAT door which is easier to install and has a higher water stop effect than conventional devices.

[0008] In addition, in the waterproofing device for the PAT door according to the present invention, the door body further has a second adhesive member provided between the surface and the first adhesive member and between the protrusion and the first adhesive member.

[0009] According to the above-mentioned configuration, the gap between the protrusion and the surface can be sealed more reliably, and thus the water-stopping effect of the PAT door can be further improved.

[0010] Also, in the method for installing a water stop device on the PAT door according to the present invention, the water stop device of the PAT door comprises a frame body, a door body, and an elastic body. The frame body is provided along an opening that communicates the outside and the inside. The door body has a surface facing the inside, a protrusion that is provided horizontally at the lower end of the surface and protrudes in a closed rotation direction that is approximately perpendicular to the horizontal direction, a pillar member, and a first adhesive member, and is rotatably connected to the frame body. The method for installing a water stop device on the PAT door comprises a process of providing the first adhesive member between the pillar member and the surface and between the protrusion and the pillar member, a process of fixing the pillar member to the periphery of the surface, and a process of fixing the elastic body to the inner periphery of the frame body.

[0011] According to the above-mentioned method, it is possible to provide a waterproofing measure for PAT doors that can be implemented on existing doors with simple work and has a high waterproofing effect. Effect of the Invention

[0014] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to this embodiment. In addition, the components in the following embodiments include those that are replaceable and easy for a person skilled in the art, or those that are substantially the same.

[0015] [Embodiment] Fig. 1 is a schematic front view showing a part of a waterproofing device of a PAT door 1 of one embodiment. Fig. 2 is a side view showing a schematic configuration of the waterproofing device of the PAT door 1 of this embodiment. As shown in Figs. 1 and 2, the PAT door 1 includes a frame body 10 and a door body 11.

[0016] The PAT door 1 of the embodiment shown in Figures 1 and 2 opens or closes an opening O1 formed in a structure S including a building, a house, a warehouse, etc. The opening O1 is formed so as to communicate between a first space side (e.g., an outdoor space side) and a second space side (e.g., an indoor space side) of the structure S.

[0017] The PAT door 1 of this embodiment is a so-called airtight door (watertight door) that has a prong on each side of the door that bites into the airtight rubber of the door frame to enhance adhesion. The PAT door 1 opens and closes the door body 11 to allow people to enter and exit the structure S through the opening O1.

[0018] In the following description, the rotation direction when the door body 11 is rotated to the closed position may be referred to as the "closed rotation direction", and the rotation direction when the door body 11 is rotated to the open position may be referred to as the "open rotation direction". The closed rotation direction is typically a direction along which water may flow when there is a possibility that water may infiltrate from one space side (outdoor space side) to the other space side (indoor space side) through the opening O1. In other words, the water flow direction is typically the upstream side when the open rotation direction is the upstream side, and the downstream side when the closed rotation direction is the downstream side. In other words, the downstream side (indoor space side) is the side where water infiltration is to be prevented or suppressed, and the upstream side (outdoor space side) is the side from which water that may infiltrate flows. The outdoor space side and the indoor space side are terms for convenience that mean the upstream side and downstream side when water may infiltrate, and the present invention can also be applied to doors installed in places where the concepts of a house or a room are not necessarily clear, such as a passageway such as a corridor.

[0019] The frame body 10 is provided along the edge of the opening O1 of the structure S. The frame body 10 is a four-sided frame type that includes a pair of vertical frame members 100, an upper frame member 101, and a lower frame member 102.

[0020] The pair of vertical frame members 100 are provided on each end surface along the height direction of the opening O1. The pair of vertical frame members 100 face each other in the width direction of the opening O1 with the space of the opening O1 between them, and are provided as a pair on the left and right in the door width direction.

[0021] The upper frame member 101 and the lower frame member 102 are each provided on an end face along the width direction of the opening O1. Here, the upper frame member 101 is provided along the width direction of the opening O1 at the upper edge in the height direction of the opening O1. The upper frame member 101 connects the upper ends of the pair of vertical frame members 100 to each other.

[0022] The lower frame member 102 is provided along the width direction at the lower edge of the opening O1. The lower frame member 102 connects the lower ends of the pair of vertical frame members 100. The upper frame member 101 and the lower frame member 102 face each other in the height direction, sandwiching the space of the opening O1 therebetween.

[0023] The frame body 10 is configured such that the ends of the pair of vertical frame members 100 are connected to the ends of the upper frame member 101 and the lower frame member 102 along the edge of the opening O1, and is configured as a ring-shaped square shape corresponding to the opening O1 as a whole. Here, the pair of vertical frame members 100, the upper frame member 101, and the lower frame member 102 are each formed with a hollow cross-sectional shape made of a plate-shaped metal material. The pair of vertical frame members 100 are each formed with a substantially T-shaped hollow cross-sectional shape made of a plate-shaped metal material. The frame body 10 is fixed to the structure S so as to surround the periphery of the opening O1. The pair of vertical frame members 100, the upper frame member 101, and the lower frame member 102 are watertightly connected to each end face of the opening O1 by caulking material or the like.

[0024] Furthermore, the frame body 10 has holding portions 103 for holding the water stop rubber 13 (described later) and the like on the spatial side of the opening O1 in each of the vertical frame members 100, the upper frame member 101, and the lower frame member 102. The holding portions 103 are configured in an annular square shape as a whole along each of the vertical frame members 100, the upper frame member 101, and the lower frame member 102 of the frame body 10.

[0025] 2, the retaining portion 103 is provided with a water-stopping groove 103a that opens to the side in the direction of rotation when opened, i.e., to the outdoor space side. The water-stopping groove 103a is configured along the vertical frame member 100, the upper frame member 101, and the lower frame member 102 in an overall circular square shape.

[0026] The waterstop rubber 13 is interposed between the frame body 10 and the door body 11 in the closing rotation direction when the door body 11 is in the closing position. The waterstop rubber 13 is attached to the entire circumference of the frame body 10, which is one of the frame body 10 and the door body 11, and abuts against the door body 11 in the closing position closing the opening O1, thereby stopping water from passing between the frame body 10 and the door body 11 and stopping water from passing through the opening O1. The waterstop rubber 13 in this embodiment will be described as being provided on the frame body 10 side, but is not limited to this and may be provided on the door body 11 side. The waterstop rubber 13 is an example of an elastic body.

[0027] The water-stop rubber 13 is an elastic member (rubber) having a predetermined elasticity, and for example, a closed-cell resin (rubber) material or a softer resin without bubbles can be used.

[0028] The waterstop rubber 13 of this embodiment is formed of a single belt-shaped member, and is attached in the waterstop groove 103a of the pair of vertical frame members 100, the waterstop groove 103a of the lower frame member 102, and the waterstop groove 103a of the upper frame member 101, and is continuously connected so that both ends are in close contact with each other in the waterstop groove 103a of the upper frame member 101. That is, the waterstop rubber 13 is formed as a single piece continuously along the lower frame member 102 and the pair of vertical frame members 100 and the upper frame member 101, and both ends are connected on the upper frame member 101. The waterstop rubber 13 may be attached in each of the waterstop groove 103a of the pair of vertical frame members 100, the waterstop groove 103a of the lower frame member 102, and the waterstop groove 103a of the upper frame member 101, and the contact portions of two adjacent waterstop rubbers 13 may be bonded with double-sided tape or the like. The watertight rubber 13 is configured as a frame-like square shape corresponding to the frame 10 as a whole.

[0029] The door body 11 is an opening / closing body rotatably supported by the frame body 10. That is, the door body 11 opens or closes the opening O1. The door body 11 of this embodiment is a single-leaf door. The door body 11 is configured as a rectangular panel-shaped member as a whole by assembling a plate-shaped door surface material 111 from both sides to an assembly of a frame member 110 such as a frame, a vertical bar, and a horizontal bar. In this embodiment, the door surface material 111 on the closed rotation direction side, i.e., the indoor space side, and the frame member 110 are fixed by welding, and a welded portion 112 is formed between the door surface material 111 on the indoor space side and the frame member 110. The door surface material 111 on the indoor space side and the frame member 110 may be bonded and fixed by an adhesive.

[0030] Fig. 3 is an enlarged side view of the tip 113 of the water stop device of the PAT door 1 of this embodiment. As shown in Fig. 3, the door surface material 111 on the side of the rotation direction when closed has an inner surface 1110. The inner surface 1110 is an example of a surface. The inner surface 1110 faces the rotation direction when closed. The tip 113 is fixed to the lower end of the inner surface 1110 by screws. For this reason, there is a small gap S1 at the joint between the inner surface 1110 and the tip 113. Note that the method of fixing the tip 113 is not limited to this.

[0031] The tip 113 is provided horizontally and protrudes in the direction of rotation when closed. The tip 113 has an upper surface 1130 facing upward. The tip 113 abuts against the waterstop rubber 13 in the closed position, and is further pushed in the direction of rotation when closed together with the door body 11, thereby elastically deforming the waterstop rubber 13. The tip 113 is an example of a protruding portion.

[0032] Fig. 4 is an enlarged view of a portion of the waterproofing device of the PAT door 1 of this embodiment. As shown in Fig. 4, the flat bar 114 is fixed to the periphery of the inner surface 1110 of the door body 11. The flat bar 114 is formed so as to extend in the door width direction and height direction. In other words, the flat bar 114 is configured as a frame-like square shape corresponding to the periphery of the inner surface 1110 of the door body 11 as a whole. The flat bar 114 is formed with a hollow cross-sectional shape by a plate-like metal material. The flat bar 114 is an example of a pillar member.

[0033] The flat bars 114 are composed of a pair of vertical flat bars 1141 and a pair of horizontal flat bars 1142. The pair of vertical flat bars 1141 are provided on the left and right in the door width direction so as to face each of the vertical frame members 100. The vertical flat bars 1141 are provided so as to extend along the height direction.

[0034] The pair of horizontal flat bars 1142 are provided in pairs above and below in the height direction so as to face the upper frame member 101 and the lower frame member 102, respectively. The pair of horizontal flat bars 1142 are provided so as to extend along the door width direction. The respective tips of the pair of vertical flat bars 1141 are fixed by screws to the surfaces of the pair of horizontal flat bars 1142 facing the height direction.

[0035] FIG. 5 is a side view showing an enlarged portion of the waterproofing device of the PAT door 1 of this embodiment. As shown in FIG. 5, the waterproof tape 115 is fixed by adhesion between the flat bar 114 and the inner surface 1110 in the closed rotation direction, and between the upper surface 1130 of the sword tip 113 and the flat bar 114 in the height direction. The waterproof tape 115 is adhered in an L-shape along the periphery of the flat bar 114. That is, the waterproof tape 115 is fixed along a frame-like square shape corresponding to the periphery of the inner surface 1110 of the door body 11 as a whole. The waterproof tape 115 may be adhered to the flat bar 114, or may be adhered to the inner surface 1110 and the aluminum tape 116 described later. The waterproof tape 115 is an example of a first adhesive member.

[0036] The aluminum tape 116 is fixed by adhesion between the inner surface 1110 and the water stop tape 115 in the rotation direction when closed, and between the upper surface 1130 of the tip 113 and the water stop tape 115 in the height direction. The aluminum tape 116 is adhered to the inner surface 1110 and the upper surface 1130 of the tip 113. The aluminum tape 116 is provided so as to follow the periphery of the inner surface 1110. In other words, the aluminum tape 116 is fixed along a frame-like square shape that corresponds to the periphery of the inner surface 1110 of the door body 11 as a whole. The aluminum tape 116 is an example of a second adhesive member.

[0037] As shown in FIG. 1, the door body 11 is provided with a door knob 118 for opening and closing the door body 11 at one end in the door width direction. The door body 11 is provided with a hinge 120 at the other end in the door width direction. The hinges 120 are provided with three rotation axes parallel to the height direction at positions offset in the height direction, and support the door body 11 rotatably relative to one vertical frame member 100 of the frame body 10. The hinges 120 of this embodiment are provided at three positions spaced apart in the height direction. The number of the hinges 120 is not limited to this. The door body 11 is provided with a latch (not shown) that engages with an engagement hole (not shown) formed in the vertical frame member 100 of the frame body 10 on the end face on the one end side in the door width direction.

[0038] The door body 11 has a base end side where the hinge 120 is provided in the horizontal direction as the hanging side (in other words, the door tail side), while the opposite side to the hanging side, i.e., the tip end side where the latch is provided as the door tip side. The door body 11 may further include a door closer (not shown) or the like.

[0039] Therefore, the door body 11 can rotate relative to the frame body 10, with the rotation axis of the hinge 120 as the rotation center, between a closing position where the opening O1 is closed and an opening position where the opening O1 is opened. When the door body 11 is in the closing position, the latch engages with an engagement hole formed in the vertical frame member 100. When the door body 11 is rotated relative to the frame body 10 from the closing position toward the opening position, it advances toward the outdoor space and opens the opening O1.

[0040] When entering or exiting the structure S through the opening O1 of the PAT door 1 configured as described above, a user operates the doorknob 118 or the like to rotate the door body 11 between the open position and the closed position by the hinge 120. At this time, when the door body 11 is in the closed position, the waterstop rubber 13 comes into contact with the door body 11 and elastically deforms.

[0041] In addition to the opening O1 of the PAT door 1, a wire hole O2 that communicates between the first space side and the second space side of the structure S may be provided. Fig. 6 is a cross-sectional view showing the wire hole O2 provided in the structure S of this embodiment. As shown in Fig. 6, the wire hole O2 is provided when passing a cable C such as an electric wire between the first space side and the second space side of the structure S. Since the wire hole O2 is often not waterproofed, when the building is flooded due to a flood or the like, there is a risk that water will infiltrate from the outdoor space side to the indoor space side through the wire hole O2.

[0042] In order to prevent water from entering from the outdoor space side to the indoor space side through the wire hole O2, a wire member T may be provided in the wire hole O2 provided in the structure S. FIG. 7 is a diagram showing the wire member T provided in the wire hole O2 of this embodiment. As shown in FIG. 7, the wire member T is a tube formed in a substantially circular flat plate shape. For example, a cross-shaped slit is provided in the center of the wire member T. The shape of the slit is not limited to this, and slits may be provided radially from the center of the wire member T. The wire member T is filled with a sealing material M from the outdoor space side or the indoor space side. Then, the wire hole O2 on the outdoor space side and the indoor space side is filled with the sealing material M and sealed, thereby making the wire hole O2 waterproof.

[0043] The method of installing the wire-passing member T will be described below. First, the wire-passing member T is attached to the wire-passing portion of the structure S to be waterproofed. The wire-passing portion is provided with a wire-passing hole O2 through which the cable C can be passed. The wire-passing member T is fixed to the wire-passing portion of the structure S by, for example, screwing.

[0044] Then, the cable C is passed through the slit in the wire-passing member T and fixed near the center of the wire-passing hole O2, for example, manually by an operator. Next, the sealing material M is filled from the outdoor space side so as to cover the surface and outer periphery of the wire-passing member T, thereby sealing the outdoor space side of the wire-passing hole O2.

[0045] Furthermore, sealing material M is filled into the slits of the wire-passing member T from the outdoor space side, and the sealing material M is poured into the indoor space side of the wire-passing member T. This prevents the sealing material M from coming off due to water pressure applied from the outdoor space side. Note that in this installation method, the sealing material M is filled from the outdoor space side, but the sealing material M may also be filled from the indoor space side. Even in this case, the indoor space side of the wire-passing hole O2 is sealed, and the sealing material M is poured into the outdoor space side of the wire-passing member T, thereby making the wire-passing hole O2 waterproof. The above method is used to perform waterproofing of the wire-passing hole O2 of the structure S.

[0046] [Water stop device installation method and water stop principle] The method of installing the water stop device of the PAT door 1 and the water stop principle will be described below with reference to Fig. 5. First, with the flat bar 114 (pillar member) not fixed to the inner surface 1110 (surface) of the door body 11, aluminum tape 116 (second adhesive member) is adhered in an L-shape from the lower end of the inner surface 1110 of the door body 11 to the upper surface 1130 of the tip 113 (protruding part). At this time, the gap S1 at the joint between the inner surface 1110 and the tip 113 is blocked by the aluminum tape 116. As a result, the aluminum tape 116 stops water leakage occurring from the gap S1.

[0047] Next, a waterproof tape 115 (first adhesive member) is adhered in an L-shape between the flat bar 114 and the inner surface 1110 in the rotation direction when closed, and between the upper surface 1130 of the point 113 and the flat bar 114 in the vertical direction.

[0048] Then, the flat bar 114 is fixed to the inner surface 1110 of the door body 11. The flat bar 114 is fixed to the inner surface 1110 of the door body 11 by, for example, screwing, but is not limited to this.

[0049] When the waterproof tape 115 is not adhered to the flat bar 114, and the door body 11 is closed with the flat bar 114 fixed to the inner surface 1110 of the door body 11, a gap S2 exists between the upper surface 1130 of the tip 113 and the flat bar 114. The waterproof tape 115 has the function of sealing this gap S2 to stop water.

[0050] The flat bar 114 and the waterproof tape 115 cover the gap S1 that is not completely covered by the aluminum tape 116 by overlapping the aluminum tape 116. In other words, the flat bar 114 and the waterproof tape 115 have the effect of blocking water leaking out from the gap S1.

[0051] It is also possible to configure the gap S1 at the joint between the inner surface 1110 and the tip 113 not to be filled with the aluminum tape 116. In this configuration, the gap S1 is filled only with the flat bar 114 and the waterproof tape 115. Even in this configuration, the flat bar 114 and the waterproof tape 115 provide a sufficient waterproof effect for the gap S1.

[0052] Meanwhile, the waterstop rubber 13 (elastic body) is attached to the waterstop groove 103a of the frame body 10. As described above, the waterstop rubber 13 is continuously connected in the waterstop groove 103a of the upper frame member 101 so that both ends of the waterstop rubber 13 are in close contact with each other, but the method of connecting the waterstop rubber 13 is not limited to this. For example, the waterstop rubber 13 may be continuously connected in the waterstop groove 103a of one of the pair of vertical frame members 100 so that both ends are in close contact with each other.

[0053] In addition, in the above-mentioned method of installing the water-stopping device of the PAT door 1, the order of the process of adhering the water-stopping tape 115 to the flat bar 114 or the inner surface 1110 and the aluminum tape 116 and the process of attaching the water-stopping rubber 13 to the water-stopping groove 103a of the frame body 10 may be reversed.

[0054] From the above, the water stop device of the PAT door 1 can stop water flowing from the outdoor space side to the indoor space side by closing the gaps S1 and S2. In addition, it is possible to provide a water stop device of the PAT door 1 that is easy to install and has a high water stop effect.

[0055] In the above embodiment, the water stop device of the PAT door 1 includes a frame body 10, a door body 11, and a water stop rubber 13. The frame body 10 is provided along the opening O1 that connects the outside and the inside. The door body 11 has an inner surface 1110 facing inward, a tip 113 that is provided at the lower end of the inner surface 1110 along the width direction and protrudes in a direction approximately perpendicular to the inner surface 1110, a flat bar 114 fixed to the periphery of the inner surface 1110, and a water stop tape 115 provided between the flat bar 114 and the inner surface 1110 and between the tip 113 and the flat bar 114, and is rotatably connected to the frame body 10. The water stop rubber 13 is fixed to the inner periphery of the frame body 10. When the door body 11 is in a closing position that closes the opening O1, the water stop rubber 13 is interposed between the frame body 10 and the tip 113.

[0056] According to the above-mentioned configuration, it is possible to provide a water stop device for the PAT door 1 which is easier to install and has a higher water stop effect than the conventional device.

[0057] In this embodiment, the door body 11 further includes an aluminum tape 116 provided between the inner surface 1110 and the waterproof tape 115 and between the point 113 and the waterproof tape 115 .

[0058] According to the above-mentioned configuration, the gap S1 between the point 113 and the inner surface 1110 can be sealed more reliably, and the watertight effect of the PAT door 1 can be further improved.

[0059] Also, in the method for installing the water stop device of the PAT door 1 according to the present embodiment, the water stop device of the PAT door 1 includes a frame body 10, a door body 11, and a water stop rubber 13. The frame body 10 is provided along the opening O1 that connects the outside and the inside. The door body 11 has an inner surface 1110 facing inward, a tip 113 that is provided horizontally at the lower end of the inner surface 1110 and protrudes in a direction of rotation when closed that is approximately perpendicular to the horizontal direction, a flat bar 114, and a water stop tape 115, and is rotatably connected to the frame body 10. The method for installing the water stop device of the PAT door 1 includes a process of providing the water stop tape 115 between the flat bar 114 and the inner surface 1110 and between the tip 113 and the flat bar 114, a process of fixing the flat bar 114 to the periphery of the inner surface 1110, and a process of fixing the water stop rubber 13 to the inner periphery of the frame body 10.

[0060] According to the above-mentioned method, it is possible to provide a watertight measure for the PAT door 1 that can be implemented on an existing door with simple work and has a high watertight effect.

[0061] Although the embodiment of the present invention has been described above, the above-mentioned embodiment is presented as an example and is not intended to limit the scope of the present invention.
