    "Sealing cap for closing holes in walls and the like"
    TECHNICAL SECTOR
    The present invention relates to sealing plugs and closing holes in walls and the like, especially in walls capable of retaining a fluid.
    PREVIOUS STATE OF THE TECHNIQUE
    Sealing plugs are known for closing holes in walls comprising an elastic body and a rod so that by pulling the rod the elastic body expands radially. These types of plugs are widely used to seal the holes that usually exist in concrete walls. As is well known, concrete walls are manufactured allowing a gap between formwork panels that are arranged so that they face each other. Said panels are secured together by transverse bolts having the threaded ends and projections outside the panels to be able to thread the corresponding nuts. Once the panels are attached, the concrete is poured into the hole that is arranged as a sandwich between the formwork panels. So that the concrete, once set, does not remain adhered to the transverse bolts, these are usually lined or placed inside a protection tube (usually plastic) that is sometimes removed during formwork, and sometimes not. Once the concrete has set, the formwork panels are disassembled as well as the cross bolts. Thus, once these transverse bolts have been disassembled, these generate through holes in the concrete wall that must be closed and sealed, especially if that wall is intended to retain a fluid, such as water, to prevent water seepage.
    Thus, ES1060376 U discloses a sealing plug comprising an elastic body and a coaxially mounted rod. The elastic body comprises a

    cylindrical main body and a through hole to allow the passage of the rod. The rod comprises a head that abuts against one end of the main body, while at the other end there is a washer that acts as a stop. When the rod is pulled by the free end with the help of a riveter or similar, the elastic body is compressed between the rod head and the stop washer causing a radial expansion so that the elastic body fits over the hole in the wall of concrete.
    EXHIBITION OF THE INVENTION
    The object of the invention is to provide a sealing plug for closing holes in walls and the like, as described below.
    The sealing cap of the invention comprises an elastic body and a rod coaxially mounted. The elastic body is apt to be expanded radially by pulling the free end of the rod, which emerges out of said elastic body, once introduced into the hole to be plugged, said elastic body exerting a closing pressure against the hole. The sealing cap also comprises a drain, arranged between the elastic body and the rod, and which is communicated with the outside so that the fluid is allowed into the elastic body so that said fluid exerts a pressure against the elastic body , thereby increasing the closing pressure exerted by the elastic body against the hole.
    With the plug of the invention it is possible to improve the tightness of the hole in the wall, wall or the like that it is desired to cover by increasing the closing force that said plug exerts on the hole in a simple, economical and reliable manner. The plug when it is compressed extends radially exerting a closing force against the hole that it is desired to plug, a force that the plug of the invention is capable of increasing, which is especially advantageous when the holes to be plugged are arranged for example in the wall of a dam. In a dam, the pressure that water can exert on the plug can be of great magnitude, so the closing force exerted by the plug must be high.

    DETAILED EXHIBITION OF THE INVENTION
    The sealing plug 1 according to a preferred embodiment of the invention is capable of sealing a hole 4 of a wall or wall 4b that can retain a fluid 4c. In a non-limiting example, said wall 4b is a wall of a water dam or a water tank although it is not ruled out that the wall 4b can retain other types of fluids such as oil, lubricant, etc.

    The plug 1, according to the non-limiting example of the figures, comprises an elastic body 2 and a rod 3 coaxially mounted as shown in Figure 1 and more in detail in Figure 3. The elastic body 2 is suitable to be radially expanded by pulling the free end 3a of the rod 3, which emerges out of said elastic body 2, once inserted into the hole 4 to be plugged. The elastic body 2, when expanding radially, exerts a closing pressure P1 against the hole 4 closing and sealing said hole 4, obtaining a closing position.
    The plug 1 also comprises a drain 5 that is disposed between the elastic body 2 and the rod 3. This drain 5 is communicated with the outside, so that the entry of the fluid, usually water, into the elastic body 2 is allowed to that said fluid exerts a pressure P2 against the elastic body 2, thereby increasing the closing pressure P1 exerted by the elastic body 2 against the hole 4.
    If the hole 4 to be plugged is contained, for example, in the wall of a dam, it is very important that the closing pressure P1 exerted by the elastic body 2 on the hole 4 is such that it prevents the pressure exerted by the water of the dam it can overcome said closing pressure P1, in which case the plug would cease to perform its function.
    As seen in Figures 1, 2 and 3, one end of the rod 3 is disposed inside the elastic body 2 while the opposite end, that is the free end 3a, emerges from one end of the elastic body 2. Said free end 3a preferably comprises a pointed shape to facilitate insertion into a riveter or similar tool.
    As can be seen in Figure 3, the cap 1 of the invention according to the preferred embodiment comprises a first stop washer 6a disposed adjacent to the end of the stopper 1 where the free end 3a of the stem 3 emerges, and a second washer of stop 6b arranged near the opposite end, so that compression of the plug 1 between said two stop washers 6a and 6b is possible, as will be detailed below. Said second stop washer 6b

    preferably it is arranged inside the elastic body 2, as seen in the example of figure 3.
    The rod 3 of the cap 1 of the preferred embodiment comprises a main rod 3 ’, preferably cylindrical, attached to a head 3’ of larger diameter. The free end 3a that emerges out of the elastic body 2 corresponds to the free end of said main rod 3 ’. The head 3 'of the rod 3 is disposed inside the elastic body 2 so that it is arranged in front of the second stop washer 6b.
    The cap 1 according to the preferred embodiment of the invention also comprises a rivet sleeve 9, preferably of circular section. The rod 3 is disposed inside said jacket 9 in a concentric manner and so that the head 3 '' of the rod 3 is supported on one end of the jacket 9, specifically on the end of the jacket 9 which is arranged closer to the second stop washer 6b. At the opposite end, the rivet jacket 9 comprises a protuberance 9 ’of greater diameter that rests on the first stop washer 6a.
    When the rod 3 is pulled by its free end 3a by means of a riveter or similar tool, the head 3 '' of the rod 3 exerts a compression pressure against the rivet sleeve 9 which at least partly deforms because the rivet shirt 9 is locked between the first stop washer 6a and the head 3 '' of the rod 3, as shown in figure 3. The part of the jacket 9 disposed between the head 3 '' of the rod 3 and the second washer 6b is the one that deforms most, which allows said part of the deformed jacket 9 to exert a compression pressure against the second stop washer 6b. Therefore, the plug 1 is compressed between the first stop washer 6a and the second stop washer 6b.
    When the plug 1 is compressed, consequently a radial expansion thereof occurs. The expansion continues until the rod 3 is broken by a slit, arranged next to the head 3 '(as shown in Figure 3), which comprises the main rod 3' of the rod 3.
    The first butt washer 6a, the second butt washer 6b and the liner

    Rivet 9 are rigid materials, that is, materials that do not recover the initial shape in case they are deformed, therefore, once the breakage of the rod 3 has occurred, the rivet jacket 9 is the one that maintains the compression force necessary to keep the elastic body 2 deformed.
    Thanks to the radial expansion of the elastic body 2, it adapts and adjusts to the inner face of the hole 4, exerting the radial closing pressure P1 against said hole 1, plugging and sealing said hole 4 internally.
    The cap 1 according to the preferred embodiment of the invention reinforces said closing pressure P1 with the pressure that the fluid 4c that is retained by the wall 4b can exert. For this, the first stop washer 6a of the preferred embodiment of the invention comprises at least one passage opening 7 which allows the emptying 5 to be communicated with the outside, that is to say with the fluid 4c (in case the wall 4b retains any type of fluid), such as water in the case of a water dam or a water tank, swimming pool, etc.
    In the non-limiting example of the figures, the first stop washer 6a comprises four passage openings 7 arranged equidistant around the center of the first stop washer 6a and at the same radial distance from the center of said first stop washer 6a , as shown in Figure 4, although the number of openings 7 and the relative position of said openings 7 is not essential for the invention.
    As can be seen in the figures, the drain 5 is disposed between the elastic body 2 and the rivet jacket 9, therefore, the fluid 4c (for example water) that can enter the cap 1 will exert a pressure P2 directly against the elastic body 2 on its inner face, thereby increasing the closing pressure P1 exerted by the elastic body 2 against the hole 4 due to the radial expansion thereof.
    In the preferred embodiment of the invention, the elastic body 2 comprises a substantially cylindrical main body 2a and, as shown in the figures, comprises a closed end with a flared shape, although said shape is not relevant for the invention. The second stop washer
    5
    10
    fifteen

    35
    6b is disposed near said closed end. Said closed end makes it possible to seal the cap 1 itself, that is, the fluid 4c that enters the elastic body 2 through the passage openings 7 does not pass through the cap 1.
    During the construction of the wall 4b, for example of concrete, so that said concrete once set does not remain adhered to the transverse bolts, which once extracted will cause the holes 4 to be plugged and sealed, these are usually previously lined with a protection tube 8, preferably of plastic, which is sometimes removed during release, and sometimes not, as is known by the person skilled in the art.
    In situations where said protection tube 8 is not removed from the concrete wall 4b, the sealing of the inner diameter of the hole 4, ie the sealing of the inner diameter of the protection tube 8 in this case, does not prevent leakage between the outside of the protection tube 8 and the concrete wall 4b. To avoid such leaks, the elastic body 2 of the sealing plug 1 according to the preferred embodiment of the invention may optionally comprise a head 2b, of greater diameter, attached to the main body 2a, so that in the closing position said head 2b exercises an axial closing pressure P3 against the wall 4b of the hole 4 to be plugged, as can be seen in Figure 8. Thus, a seal from the outside is also ensured without the need for additional sealing means such as toric joints, putties. , cement or similar, which is very advantageous to seal the holes in the walls of a dam or a water tank in a reliable, economical and simple way, since no special skills are required to seal said hole on the outside.
    In situations where if the protection tube 8 is removed or said tube 8 does not exist, the head 2b would not be necessary to guarantee the hermetic sealing of the hole 4, but its use is advised since said head 2b stops against the wall 4b, as can be seen in figures 5 and 6, preventing the plug 1 from entering the hole too much 4. Likewise, an axial closing pressure P3 against the wall 4b will always improve the sealing of the hole 4 and avoid any filtration in the longitudinal direction due for example to a crack that may be present in the wall 4b.

    By pulling the free end 3a of the rod 3, at least part of the head 2b changes its geometry to adapt and adjust to the shape of the outer contact wall 4a, exerting an axial closing pressure P3 on the wall 4b before it is cause the breakage of the rod 3. If the outer contact wall 4a has irregularities, cracks, etc., these will be sealed with the head 2b, as can be seen in figures 6 and 8.
    In the preferred embodiment of the invention, the drain 5 is substantially cylindrical and extends along the main body 2a and the head 2b, as shown in Figure 3. Optionally, in a variant not shown in the drawings , the emptying 5 of the head 2b can be greater, at least in diameter, than the emptying 5 of the main body 2a, which favors the fluidity of the head 2b allowing the material to flow more easily and better adapt to the geometry of the outer contact wall 4a. The more the head 2b is deformed, the plug 1 will cover more portion of the outer contact wall 4a that surrounds the hole 4 to be plugged, therefore the area of the hole 4 to be sealed will increase.
    According to the preferred embodiment of the invention, the main body 2a and the head 2b form a single piece, but optionally, both pieces can be joined being both pieces independent of each other.
    Preferably the rod 3 of the cap 1 of the invention is a rivet.
    To seal the hole 4 of a wall 4b (as shown in Figures 5 or 7), the plug 1 is inserted into said hole 4 so that the main body 2a and possibly at least part of the head 2b are arranged in the inside the hole 4. The plug 1 of the invention is suitable to be inserted in the hole 4 and be accessible by a single access point, which is advantageous for sealing holes 4 arranged in walls 4b of considerable thickness.
    On the other hand, at least part of the head 2b, having a diameter larger than the main body 2a and which the hole 4 to be plugged, is disposed outside said hole 4 so that it abuts against the wall 4b itself, that is against the external contact wall 4a. As most of the holes comprise a first conically shaped part, the head 2b of the elastic element 2 according to the preferred embodiment
    of the invention comprises a preferably conical shape so that the cap 1 fits or seats better both in the hole 4 and in the outer contact wall 4a.
