Waterproofing device

Abstract

Conventional technology makes it easier to shorten the length of the casing in the front-to-back direction, but it has a complex structure, is costly, may not operate during a power outage, and cannot be retrofitted as in the present invention. Furthermore, other conventional technologies also involve dedicated machines, and these, too, cannot be retrofitted in the way of the present invention. [Solution] The mounting body is roughly U-shaped and designed to be attached to the guide rails of a shutter and / or entrances inside and outside a building. It is characterized by having multiple fastening points on the mounting body, and a water-stopping device with a roughly U-shaped water-stopping section corresponding to the fastening points, located on both the left and right sides, as well as a water-stopping plate that can be detachably attached to the water-stopping device.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The former conventional technology is easy to shorten the length of the casing in the front-rear direction, but it has a complex structure, high cost, and may not operate during a power outage, and it is not the type that can be retrofitted like the present invention.

[0006] Furthermore, the latter also consists of a dedicated machine and is not something that can be retrofitted as in the present invention.

[0007] The present invention solves the problems of such conventional configurations and aims to provide a shutter waterproofing device that can be retrofitted to shutter guide rails, building gateposts, etc. [Means for solving the problem]

[0008] To achieve the above objective, the present invention provides a generally U-shaped mounting body for attachment to the guide rail of a shutter and / or a gatepost at the entrance of a building, with a plurality of fastening parts, and a water-stopping device provided on each side, each having a generally U-shaped water-stopping part corresponding to the fastening parts, and a water-stopping plate that can be detachably attached to the water-stopping device. The fastening parts are made of bolts with a pressing plate at the tip. The water-stopping parts are made of flat rubber. The water-stopping plate has a horizontal length that fits between the water-stopping parts on both sides, and a vertical length that is the height of the water-stopping device. The water-stopping plate has a waterproofing material provided at the lower end of the main body. The water-stopping devices are fixed to the back of each mounting body. The waterproofing device according to claim 6 is characterized by being provided with a foldable support. [Effects of the Invention]

[0009] 1) It can be attached to the guide rails of shutters, gateposts of buildings, etc., and although it has a simple structure consisting of a water stopper and a water stop plate, it can be installed as an afterthought and can reliably provide waterproofing in the event of flooding. 2) The water-stopping section ensures a secure seal against the water-stopping plate, providing waterproofing. 3) By pressing the water-stopping portion with the fastening portion, leakage from the water-stopping plate can be reliably prevented. 4) By providing waterproofing material on the underside of the water-stopping plate, water ingress can be prevented more reliably. 5) By fixing the water-stopping device to the back of each mounting body, it can be attached, for example, to a guide rail when multiple shutters are installed in series. 6) With the support device, it can be installed in locations other than the shutter's guide rails.

[Figure 9] A side view showing the installation state of a waterproofing device illustrating a third embodiment of the present invention. [Modes for carrying out the invention]

[0011] 1 is a waterproofing device comprising water-stopping devices 1A and 1B, described later, arranged symmetrically on both sides. 2 is a mounting body that is roughly U-shaped in plan view. 3 is a roughly U-shaped water-stopping part made of rubber or the like, with one side of 3a bonded to the inner surface of the mounting body 2. 4 is a fastening part that is attached to the mounting body 2 and tightens the water-stopping part 3, and the tip of the bolt 4a is rotatably connected to a pressing plate 4b that presses against the water-stopping part 3 inside the mounting body 2. 1A and 1B are waterproofing devices consisting of a mounting body 2, a waterproofing section 3, and a fastening section 4. (Figures 1 and 2) P is a water stop plate provided by being inserted between opposite water stop parts 3·3, and a waterproof material S (such as sponge, water stop rubber, highly water-absorbent polymer, etc.) is provided at the lower end of the main body H made of wood, iron plate, resin, etc. Note that the size of the main body H has a horizontal length equal to the length between the water stop parts 3·3, and the height is the dimension of the waterproof tools 1A·1B. (Figs. 3 and 4)

[0012] The construction example of the above waterproof device 1 will be described below. For example, in a shutter ST composed of a guide rail GR that supports a slat SR that moves up and down and is provided in a case KS installed at the entrance of an office, store, etc., in order to attach the water stop tools 1A·1B of the waterproof device 1 to the guide rails GR on both sides, the attachment main body 2 is fixed by an adhesive or welding, etc.

[0013] Subsequently, the water stop body P is inserted from above the water stop parts 3·3, and by rotating each bolt 4a of the tightening part 4, the pressing plate 4b presses the water stop parts 3·3, so that both ends of the water stop parts 3·3 and the water stop plate P are surely in close contact, and water stop can be achieved.

[0014] In this state, even if water tries to infiltrate inside due to a flood or the like, reliable waterproofing can be achieved by the waterproof material S.

[0015] Next, the waterproof device 21 of the second embodiment will be described. The waterproof device 21 is formed by fixing the water stop tools 1A·1B of the first embodiment to the backs of the attachment main bodies 2·2. This waterproof device 21 is, for example, attached to the guide rails other than those on both sides when a plurality of shutters are continuously provided.

[0016] Subsequently, the waterproof device 31 of the third embodiment will be described. The waterproof device 31 is formed by forming a support tool 5 that is foldable, in the waterproof device 21, by forming an attachment plate 5a1 provided with a hinge C at the upper part of the support main body 5a and providing a fixing plate 5b having an anchor attachment hole 5b1 that vibrates with the hinge C at the lower part.

[0017] This waterproofing device 31 can be used in various places, such as shops and offices without shutters, or in front of automatic ticket gates at station entrances. The lower part is embedded in the ground level (GL) of the floor (concrete surface, soil surface, etc.), and a case K for storing the support 5 is provided at the front, which can be easily inserted and removed. During installation, anchor bolts AB are screwed in through anchor mounting holes 5b1 to secure it.

[0018] Furthermore, the waterproofing device can be installed not only on shutters, but also on gateposts at entrances to homes, factories, and subways (such as stairwells). Furthermore, the material and size of each component can be determined as needed, and there are no particular limitations as long as they have similar functions. Furthermore, the pressure plate can be a single piece or divided into sections. Furthermore, it is worth considering creating grooves in the ground (floor) or other areas to accommodate the area beneath the water-stopping plate. [Explanation of symbols]
