Description

The present invention relates to waterproof shutters.

In recent years, guerrilla rainstorms have frequently occurred due to abnormal weather, and rainwater inundation accidents have occurred in subway premises and building basements in urban areas. There is a case where it is desired to prevent external water from entering the building by installing it at the entrance of a building or the like in an emergency. In addition, there are cases where it is desired to close the opening of the building in a water-stopped state to prevent water from entering the building, not only during a torrential downpour.

As exemplified in Patent Literature 1, there has been proposed a waterproof shutter that closes a building opening in a water-stopping state. There is a case where such a waterproof shutter is desired to function as a fireproof/smokeproof shutter. For example, when a waterproof shutter is used for normal opening and closing of a building opening as a panel shutter for management purposes, it may be desirable to have fireproof and smokeproof performance when the opening is normally fully closed.

However, since the panel of the conventional waterproof panel shutter disclosed in Patent Document 1 is made of aluminum, it has relatively low heat resistance and fire resistance. may melt and form a gap connecting the fire side and the non-fire side in the fully closed opening blocked by the shutter curtain.

In order to improve the heat resistance and fire resistance of shutter curtains, it is conceivable to adopt steel panels, but steel panels are manufactured by combining steel plate surface materials formed into a predetermined shape by welding. Therefore, there is a drawback that the strength is generally lower than that of an aluminum panel formed of an extruded aluminum material.

When the shutter curtain is in the fully closed position, each panel is subjected to the weight of the panel positioned above it, and when the vertical pressure is applied by the vertical pressure means, a vertical pressure force acts on each panel. When constructing a shutter, it is important to deal with the vertical load acting on the panel.

[A] Construction of Panel Shutter The waterproof shutter according to this embodiment is composed of a panel shutter and has the basic structure of a panel shutter. As shown in FIGS. 1 to 4, the shutter curtain 1 of the waterproof shutter according to the present embodiment includes a top panel 2 (sometimes abbreviated as "panel 2"), a plurality of intermediate panels 3 (hereinafter , “panel 3”) and a bottom panel 4 (which may be abbreviated as “panel 4”) are connected in the panel height direction. Also, it should be noted that the term “panel” used in this specification basically includes the top panel 2 , panel 3 and bottom panel 4 . In this embodiment, the bottom panel 4 includes a bottom panel main body 4' (also abbreviated as "panel main body 4'" or "main body 4'") and a movable seat plate 6 ("seat plate 6"). may be omitted). The waterproof shutter according to this embodiment has fireproof and smokeproof performance in addition to waterproof performance, and each panel 2, 3, 4 is a steel panel made of steel with excellent heat resistance and fire resistance. In one respect, it differs from conventional aluminum panels. The detailed configuration of each panel 2, 3, 4, the waterproof structure of the waterproof shutter according to the present embodiment, and the fireproof/smokeproof structure will be described in detail later. In this specification, the terms "outdoor side" and "indoor side" refer to the "outdoor side" and "indoor side" across the opening that is opened and closed by the shutter curtain 1. Note that it is also used to express the relative position of .

The basic structure of the panel shutter will be explained. Support shafts 10 provided with guide rollers 11 protrude from both ends of the panels 2, 3, and 4 constituting the shutter curtain 1 (see FIGS. 5 and 6). , 4 form the shutter curtain 1 by being connected to a chain (not shown) via a support shaft 10 and suspended. In the panel shutter, a structure in which a plurality of panels are hung by chains is well known to those skilled in the art, so detailed description thereof will be omitted.

Left and right guide bodies 5 are erected at both ends of the opening of the building in the width direction so as to receive and guide both ends of the shutter curtain 1 in the vertical posture in the width direction. As shown in FIGS. 5 and 6, the guide body 5 is formed in a U-shape in cross section from a first side wall 50 on the outdoor side, a second side wall 51 on the indoor side, and a bottom wall 52, which are opposed to each other. It is a structure extending in the height direction of the opening, and an outdoor-side bent piece 500 and an indoor-side bent piece 510 are formed so as to face each other at the leading end sides of the first outdoor side wall 50 and the indoor side second side wall 51 . , the ends of the shutter curtain 1 (the top panel 2, the panel 3, and the bottom panel 4) are received in the opening grooves between the ends of the outdoor-side folding piece 500 and the indoor-side folding piece 510, respectively. A bottom wall 52 of the guide body 5 is provided with a guide member 53 which is an elongated member extending vertically in the height direction and which contacts and guides the outdoor side peripheral surface of the guide roller 11 . Long fins 54 (for example, made of nylon) are formed. The upper end of the guide member 53 extends into the storage space above the opening and has an upper extension 5' (see FIG. 2). It is configured to be accessible from both indoor sides.

In the storage space above the opening, a sprocket 12 for winding a chain is provided at substantially the upper end of the upper extension 5', and the sprocket 12 is rotated by the opener M to lift the chain. Alternatively, by extending the shutter curtain 1, the shutter curtain 1 is raised or lowered to open and close the opening of the building. The storage space for the shutter curtain 1 above the opening extends from above the opening toward the indoor side, and the storage space has a gentle downward slope from the front (outdoor side) to the rear (indoor side). An extending storage rail 13 is provided. By lifting the chain, the panels 2, 3 are relayed to the storage rail 13 via the sprocket 12, and the guide rollers 11 are guided by the storage rail 13 and sequentially sent to the rear of the storage space. 4 are held and housed in a state in which they hang parallel to each other.

The panel shutter according to this embodiment is an electric panel shutter, and the electric opening/closing of the shutter curtain 1 is performed by operating the opening/closing switches (not shown) in the switch boxes SB1-SB3. When the opening switch (not shown) is pressed in the fully closed state of the opening and the sprocket 12 is rotationally driven in the chain lifting direction by the opening/closing device M, the shutter curtain 1 in the fully closed vertical position moves up as the chain rises. , while both ends in the width direction are guided by the vertical guide body 5, the top panel 2 is sequentially transferred to the storage rails 13 extending in the lateral direction from the upper extension part 5' of the guide body 5. , are stored in parallel in the storage space, and the opening is opened.

When the opening is fully opened, a closing switch (not shown) is pushed and the sprocket 12 is driven to rotate in the chain feeding direction by the opening/closing machine M. 11 are sequentially pulled out from the rear (indoor side) of the storage space to the front (outdoor side) toward the sprocket 12 side while being guided by the storage rails 13, and when passing through the sprocket 12, they assume vertical postures in the height direction. It descends while being guided by the guide body 5, and the opening is closed.

When the shutter curtain 1 descends, after the lower end of the bottom panel 4 has landed on the floor, the shutter curtain 1 continues to descend by a predetermined distance, so that any two panels adjacent to each other in the upper and lower directions are separated from the upper end portion of the lower panel. The lower end portion of the upper panel is at least partially in contact with the fully closed state (Fig. 4 center view, see Fig. 19).

The bottom panel 4 of the shutter curtain 1 according to this embodiment includes a bottom panel main body 4' and a movable seat plate 6 provided at the lower end of the bottom panel main body 4'. A detection switch SW provided at the lower end portion of the main body 4' constitutes first obstacle detection means. When the movable seat plate 6 at the lower end of the bottom panel 4 touches the floor or contacts an obstacle and moves upward by a predetermined amount, the detection switch SW is turned ON, and an obstacle detection signal is output from the cord reel CR ( is transmitted to the controller of the opening/closing machine M via a wired system), and the shutter curtain 1 that is being lowered is stopped. The control unit is preset with upper and lower limits for the shutter curtain 1, and when an obstacle detection signal is received above the lower limit, it is determined that an obstacle has been detected while the shutter curtain is descending. For example, the shutter curtain 1 during its descent is controlled so that it stops for 1 second and then reverses and rises for 1.5 seconds. It is determined that the shutter curtain 1 has landed on the surface FL), and the descent of the shutter curtain 1 is stopped without reversing and rising. Also, the transmission of the obstacle detection signal is not limited to the wired system, and may be wireless (for example, wirelessly transmitted by radio waves).

A photoelectric sensor 14 exemplified as a second obstacle detection means is provided at a lower portion of the opening at a predetermined height from the floor surface. In the illustrated embodiment, four photoelectric sensors 14 are provided at heights of 150 mm and 500 mm from the floor surface, respectively, on the outdoor side and the indoor side. The height position of the photoelectric sensor 14 is an example, and the height position is not limited. In this embodiment, when an obstacle is detected while the shutter curtain is descending, the shutter curtain that is descending stops for one second, and then reverses and ascends for 1.5 seconds, for example.

Although the basic configuration of the panel shutter has been described with reference to the drawings, the basic configuration of the panel shutter is known to those skilled in the art, and further detailed description is omitted. In addition, many modifications and improvements of the panel shutter are known to those skilled in the art, and the configuration of the panel shutter that can be applied to the waterproof shutter according to the present invention is not limited to the illustrated embodiment. Please note.

The first outdoor side switch box SB1 and the indoor side switch box SB3 are arranged at a height of 1500 mm from the floor so that the operator can easily operate them in a standing posture. The second outdoor side switch box SB2 is located at a height exceeding 3000 mm (assumed maximum water level W.L.) from the floor surface. The above height position is an example and is not limited.

An operation panel in the switch box is provided with an open button, a close button, a stop button, a pressure button, a pressure release button, and an emergency close button. The operation of the waterproof shutter is controlled based on inputs from these buttons. More specifically, in accordance with button input instructions, the opening/closing device M (up and down operation of the shutter curtain 1), the vertical compression mechanism 7 (vertical compression operation of the shutter curtain 1 in the fully closed state, vertical compression release) are controlled via the control unit. operation) and the horizontal pressing mechanism 8 (horizontal pressing operation of the shutter curtain 1 in the vertical pressing state, horizontal pressing release operation) are controlled. Each button will be described below.

The waterproof shutter according to this embodiment includes fully closed state detection means (for example, composed of a lower limit switch and a seat plate switch) for detecting that the shutter curtain 1 is in a fully closed state of the opening, and the shutter curtain 1 vertical compression state detection means (first limit switch, second limit switch) for detecting that the shutter curtain 1 is in a vertical compression state, and horizontal compression state detection means (second limit switch) for detecting that the shutter curtain 1 is in a horizontal compression state. 1 limit switch, second limit switch).

When the release button is pressed when the shutter is in the pressure-released state (vertical pressure-released state and horizontal pressure-released state) and not at the fully open position, the shutter curtain 1 rises and stops at the fully open position. When the shutter is not at the fully closed position, pressing the close button causes the shutter curtain to descend and stop at the fully closed position. When the stop button is pressed while the shutter is operating, or during pressing and releasing, the operating shutter curtain 1 stops at an arbitrary position.

When the shutter is in the fully closed position and not in the compression state (vertical compression state and horizontal compression state), pressing the compression button starts the compression operation to obtain the waterproof structure. When the pressing operation of the vertical pressing mechanism 7 is completed (a vertical pressing state signal is generated when the second limit switch of the vertical pressing mechanism 7 is turned ON), the horizontal pressing mechanism 8 starts pressing and presses in the height direction. The closed shutter curtain 1 is integrally pressed toward the indoor side. When the shutter is not in the fully closed position, the shutter curtain can be lowered by pressing the emergency closing button.

When the shutter is in the compression state, or when the compression release button is pressed while the shutter is in the fully closed position and not in the compression release state, the compression release operation is started. As one procedure, when the compression release button is pressed, first, the horizontal compression mechanism 8 starts the release operation, and when the release operation of the horizontal compression mechanism 8 is completed (the horizontal compression state is released when the first limit switch is turned ON) signal is generated), the vertical compression mechanism 7 initiates a release actuation. When the compression release operation of the vertical compression mechanism 7 is completed, the first limit switch of the vertical compression mechanism 7 is turned ON and a vertical compression state release signal is generated. If the horizontal compression state has been released, the release operation is started from the vertical compression state.

In one aspect, in addition to the operation input from the first outdoor switch box SB1, the second outdoor switch box SB2, and the indoor switch box SB3, remote operation input from a management room or the like (safety is confirmed by a surveillance camera or the like) operation) is possible. A series of operations of the shutter can be controlled by a remote operation signal, and it is also possible to perform a pressing operation and a pressing release operation by remote operation.

[E-8] Operation as Fire Shutter The waterproof shutter according to this embodiment is an electric shutter, and during normal operation, it is electrically lowered to close the opening. In the fully closed state of the opening, as described above, an airtight structure (smoke blocking structure) is formed in the outdoor part, and an airtight structure (fireproof structure) is formed between the panels adjacent to each other vertically, which is advantageous in terms of fire prevention. ) is formed. In the fully closed state (unpressed state) of the opening, the vertical compression mechanism vertically compresses the fully closed shutter curtain 1, and the horizontal compression mechanism horizontally compresses the fully closed shutter curtain 1 in the vertically compressed state. By pressing in the direction, the shutter curtain 1 in the fully closed posture becomes a vertical and horizontal pressing state. Even in this state, the airtight structure (smoke blocking structure) is maintained (see FIG. 6), and the interlocking structure (fireproof structure) is maintained (see FIG. 20).

The waterproof shutter according to this embodiment includes a dead weight lowering mechanism for lowering the fully open shutter curtain 1 under its own weight in the event of a fire or the like. More specifically, as shown in FIG. 40, the waterproof shutter includes an automatic closing device that operates upon input of a fire detection signal, and an operating mechanism that releases and restores the brake of the switch M. By the operation of the automatic closing mechanism, the operating mechanism assumes the brake releasing posture, releases the brake, lowers the shutter curtain by its own weight, and the shutter curtain descends to the fully closed position and stops in the fully closed posture. When an obstacle hits the seat plate 6 at the lower end of the shutter curtain 1 during its own weight descent, an obstacle detection signal is transmitted to the operating mechanism, and the operating mechanism assumes the brake return posture in response to the input of the obstacle detection signal. The brakes are restored and the shutter curtain, which is descending under its own weight, stops. When the obstacle is removed, the input of the obstacle detection signal disappears, the operating mechanism assumes the brake release posture again, releases the brake, lowers the shutter curtain again under its own weight, and the shutter curtain lowers to the fully closed position. Stop in the fully closed position.

A description will be given of the pressing operation after the shutter curtain assumes the fully closed posture due to the descent of its own weight. In the first mode, depending on the presence or absence of the fire detection signal, it is determined whether the shutter curtain in the fully closed posture is due to the self-weight descent or the electric descent. If the fire detection signal is "present", It is determined that the shutter curtain is in the fully closed posture due to the descent of its own weight, and the transmission of the compression signal from the compression button is disabled, and the compression operation is restricted.

In the second mode, the pressing operation is possible regardless of whether the fully closed shutter curtain is lowered by its own weight or by an electric lowering. When the vertical compression signal is sent from the compression button to the vertical compression mechanism, the vertical compression mechanism performs vertical compression of the shutter curtain in the fully closed posture, and when the horizontal compression signal is transmitted from the compression button to the horizontal compression mechanism, the horizontal Vertical compression of the fully closed shutter curtain is performed by the compression mechanism.
