Description

Technology Field

[0001] The present invention relates to a strap combined with a flood prevention bag, and more specifically, to a strap combined with a flood prevention bag characterized by upper and lower straps positioned along the seam of the flood prevention bag, and the flood prevention effect being enhanced by being fixed to the strap through the volume expansion of the flood prevention bag containing a superabsorbent resin. Background Technology

[0003] Generally, sand-filled bags are primarily used as water barriers to prevent damage caused by heavy rains or floods; however, this method incurs significant costs for sand extraction and causes environmental damage, and furthermore, the process of dismantling and storing the sand bags after use is very inconvenient.

[0004] Since mined sand has a fixed volume and weight, significant logistics costs must be incurred to transport and store it in locations requiring flood prevention. To use it as flood prevention bags when needed, it is cumbersome to assemble them individually, incurring labor costs where two people work for one hour per 60 bags. Similar inconveniences and costs arise when attempting to dismantle them after use. Furthermore, due to the nature of sand consisting of small grains, there is a problem of leakage or loss during use, transportation, and storage, requiring the replacement of such losses.

[0005] Therefore, a strap combining a flood prevention bag with a new structure was developed, utilizing a flood prevention bag with a permeable outer shell and an interior containing superabsorbent polymer (SAP) that absorbs water and expands at flood sites, without using sandbags.

Specific details for implementing the invention

[0025] Preferred embodiments of the present invention will be described in detail below. First, in describing the present invention, specific descriptions of related known functions or configurations are omitted to avoid obscuring the essence of the invention.

[0026] Terms of degree used in this specification, such as 'approximately' and 'substantially,' are used to mean at or near the stated value when inherent manufacturing and material tolerances are presented in the stated meaning, and are used to prevent unscrupulous infringers from unfairly exploiting the disclosed content in which precise or absolute values ​​are mentioned to aid in understanding the invention.

[0027] FIG. 1 is a conceptual diagram of the strap before (a) and after (b) deformation of the strap before attaching the flood prevention bag according to the present invention.

[0028] The present invention comprises a strap (10) having one or more empty spaces; and a water-permeable flood prevention bag (20) containing a superabsorbent resin (23) coupled to the empty spaces.

[0029] The above strap (10) has a straight lower strap (13) and an upper strap (11) that is continuous with the lower strap (13) and overlaps the upper surface, passes through the loops (15) at regular intervals of the lower strap (13) and continuously penetrates the slit (17) at the end of the lower strap (13).

[0030] The upper and lower straps can be made of a material that can be deformed, such as a fiber structure or styrofoam. The upper and lower straps can be connected and have the same shape, and the upper strap (11) can have a shape with a smaller cross-sectional area.

[0031] The upper strap (11) is folded from the lower strap (13) and overlapped on top of the lower strap (13). When not in use, the upper and lower straps can be overlapped so that there is no space between them, and the flood prevention bag (20) can be tightly attached to the space between the upper strap (11) and the lower strap (13) before expansion.

[0032] To create a space between the upper and lower straps (13), the upper strap (11) is joined by passing through the evenly spaced loops (15) of the lower strap (13) and is joined by passing through the slit (17) at the end of the lower strap (13).

[0033] FIG. 2 is a conceptual diagram of a flood prevention bag (a) before absorption and a flood prevention bag (b) after absorption in a strap combined with a flood prevention bag according to the present invention. The flood prevention bag (20) is made of a material through which water passes and contains a super absorbent resin (SAP) inside.

[0034] Superabsorbent resins (23) include white powder-type chemical substances (sodium polyacrylate, SAP) that do not dissolve when they come into contact with water and absorb 500 to 1000 times their own weight.

[0035] The shape of the flood prevention bag (20) in FIG. 2 is an example, and in the present invention, the flood prevention bag (20) is preferably in a rectangular shape, but other shapes that have a certain volume after absorbing water are also possible. There is a straight seam (21) of a certain length in the middle, and the flood prevention bag (20) is formed such that the upper surface and the lower surface are connected at a certain distance or closely joined by the seam (21).

[0036] The form in which water is absorbed is a shape in which the upper and lower surfaces are in close contact with the seam (21) as shown in Fig. 2 (b), and the upper and lower strips are positioned in this curved gap. The upper and lower straps, which are in close contact along the seam (21), have excellent contact with the flood prevention bag (20), so that the flood prevention bag (20) can be prevented from detaching from the strap (10) by external force.

[0037] However, the expanded shape of the flood prevention bag (20) can be adjusted according to the length of the seam (21) connecting the upper and lower surfaces. If there is no seam in the middle of the flood prevention bag (20), the shape that is maximally expanded by absorbing water becomes close to a spherical shape and does not occupy space in the side parts, so the area of ​​contact between adjacent flood prevention bags (20) becomes small, and thus empty space may be created, which may reduce the water barrier effect.

[0038] FIG. 3 is a conceptual diagram of a strap combined with a flood prevention bag according to the present invention.

[0039] An uneven-shaped latch (19) is present on the upper strap (11) that passes through the slit (17) at the end of the lower strap (13), thereby preventing the upper strap (11) from separating from the lower strap (13). The position of the latch (19) is installed at the part that can be most securely connected to the strap (10), taking into account the maximum absorption shape of the combined flood prevention bag (20).

[0040] FIG. 4 is a conceptual diagram of a connecting pin and a connecting ring that connect adjacent straps in a strap combined with a flood prevention bag according to the present invention, showing the before (a) and after (b) of connection.

[0041] In the present invention, the empty space of the strap (10) may be one or two or more, and can be determined depending on the situation. In addition, for the connection between the straps (10), a connecting pin (40) is added to the part where the upper strap (10) and the lower strap (10) are bent and connected, and a connecting ring (30) is added to the end of the lower strap (13), so that adjacent straps (10) can be connected by the connecting pin (40) and the connecting ring (30).

[0042] The connecting ring (30) can be made of the same material as the strap (10), and if necessary, a ring made of metal or a durable material is also possible.

[0043] The above connecting pin (40) is spaced apart with a gap in the middle, and the connecting ring (30) is connected through the gap. The spacing of the gap can be adjusted according to the width of the connecting ring (30).

[0044] The flood prevention bag (20) attached to the empty space of the strap (10) absorbs water and expands in volume, deforming the shape of the auxiliary pins (41) on both sides of the connecting pin (40) so that the gap disappears.

[0045] As the flood prevention bag (20) located in the empty space of the strap (10) expands, the curved part of the auxiliary pin (41) is deformed into a gently curved shape or a shape close to a straight line, and accordingly, the auxiliary pins (41) on both sides receive force towards the center, causing the gap of the connecting pin (40) to narrow or close.

[0046] Therefore, the combined connecting pin (40) and connecting ring (30) can connect adjacent straps (10) to make it difficult to separate the straps (10) by external force.

[0047] The high-absorption flood prevention bag (20) coupled to the strap (10) of the present invention can be installed on the ground in the form of FIG. 3 and installed on the top of the installed flood prevention bag (20) in the same form, thereby allowing the height of the flood prevention bag (20) to be adjusted. When stacking, if the expanded flood prevention bags (20) are stacked alternately on the curved part formed by the upper and lower straps (10), it can be more robust.

[0049] The present invention described above is not limited by the aforementioned embodiments and attached drawings, and it will be obvious to those skilled in the art that various substitutions, modifications, and changes are possible within the scope of the technical concept of the present invention.
