Description

Technology Field

[0001] The present invention relates to a device that allows barrier plates installed to block water or sediment flowing in due to floods, heavy rain, or landslides to be connected to one another, and also supports the barrier plates to maintain an upright state. In particular, the invention relates to a support device that can be used to stably connect and support barrier plates that effectively block water or sediment flowing in from the front direction, as well as to be used as a support for a guide sign controlling access, or as a support for a fence installed to protect facilities and property. Background Technology

[0002] Generally, barrier plates are installed to reduce or prevent damage to life and property by blocking large amounts of water flowing in due to the rainy season or heavy rain, or soil and debris flowing in due to landslides or slope collapses.

[0003] In addition, it can be used as a simple fence to protect goods or facilities, and furthermore, it can be installed and operated as cover to protect human lives from enemy small arms fire.

[0004] However, in order for such blocking plates to be connected and supported in parallel, a separate device capable of connecting and supporting the blocking plates is required, and a blocking plate support device developed for this purpose is disclosed in Korean Registered Patent No. 10-1948853 (hereinafter referred to as the 'Cited Invention').

[0005] As illustrated in FIG. 1, the cited invention allows the blocking plates (A) to be connected in parallel and stably supported by the function of a connecting member (B) that connects the blocking plates (A), a support member (100) that is rotatably coupled to the connecting member (B) to allow the blocking plates to be erected, an auxiliary support member (110) in which the end portion of a first auxiliary support member (111) that is rotatably coupled to the connecting member (B) and the end portion of a second auxiliary support member (112) that is rotatably coupled, and a fixed body (200) into which the end portion of the support member (100) is inserted and placed on the ground.

[0006] However, although the cited invention has a function of supporting it by inserting a fixing peg to prevent it from being pushed by strong water pressure, this is very cumbersome to apply to cases where it is not necessary to fix it with a sturdy fixing peg—that is, to water pressure where it is not pushed even by weak resistance. Furthermore, in cases where it is difficult to insert the fixing peg, such as on asphalt or concrete, there is an inconvenience in that the blocking plate or the blocking plate support device must be supported by a separate load body. Additionally, the support device must be folded for storage after use, but since there is no handle function to fold it safely, there is even a risk of injury from the hand getting caught in the folding part during the folding process.

[0007] In addition, there is no handle, which is a convenience device for easily handling the barrier plate support device, making it inconvenient to handle. Furthermore, there is no function to fix the barrier plate and the barrier plate support device so that they do not separate, so when installing the barrier plate, the barrier plate and the barrier plate support device must be handled separately, which is inconvenient. Moreover, if the installed barrier plate needs to be moved to another location depending on the site conditions, it would be much more convenient if the installed barrier plate could be moved as a set. However, when lifting the barrier plate or the barrier plate support device to move the barrier plate as a set, the barrier plate and the barrier plate support device separate, making it impossible to handle them as a set. Consequently, there is the inconvenience of having to handle and move the barrier plate and the barrier plate support device separately. Prior art literature

[0009] doesn't exist The problem to be solved

[0010] The present invention aims to solve the above-mentioned problems by providing a blocking plate support device with improved practicality and stability, such as a function that prevents it from being easily pushed even under weak water pressure without inserting a fixing peg, a safety handle function that prevents safety accidents from occurring during the folding process of the support device, a handle that allows the support device to be easily handled, and a function that allows the blocking plate and the blocking plate support device to be fastened and fixed, thereby enabling efficient use in various sites. means of solving the problem

[0011] Spike that restrains the jungle

[0012] In order for the cited invention to ensure that the installed blocking plate can withstand strong water pressure without being pushed backward, a sturdy fixing peg that suppresses sliding can be inserted into the ground through the through hole of the fixing body.

[0013] However, inserting fixing pegs even in situations where the water pressure is weak enough not to be pushed back by even slight resistance is not only inconvenient, but in cases where the ground is hard, such as asphalt or concrete, where fixing pegs cannot be easily inserted, the blocking plate or blocking plate support device must be supported by a separate load instead of fixing pegs.

[0014] Therefore, in order to effectively respond to water pressure that is not easily pushed by weak water pressure, or asphalt or concrete floors where fixing pegs cannot be inserted, this problem can be solved by applying spikes to the bottom surface of the fixing body that are not easily pushed by weak water pressure.

[0015] Of course, the spike method would not be very effective if the floor were hard and smooth, but in the case of ordinary asphalt or concrete, the floor is not completely smooth and usually has many gaps where sharp spikes can be embedded. Therefore, if a spike with multiple protruding sharp spikes is formed on the bottom surface of the fixed body, the protruding spikes will be embedded in the gaps of the floor and prevent slippage.

[0016] Foldable safety handle to prevent accidents

[0017] When folding the barrier plate support device, one must touch the middle part of the auxiliary support that is unfolded in a '—' shape; however, there is a risk of injury if the hand gets caught in the gap as the auxiliary support folds from the '—' shape into an 'Ʌ' shape. Therefore, to prevent such safety accidents, a separate folding safety handle can be formed to prevent the hand from touching the folding part. If the folding safety handle is formed on the top of the first auxiliary support with an extended handle portion, there is no risk of the hand getting caught during the folding process.

[0018] <Anti-folding device to prevent folding due to external impact>

[0019] If the barrier plate support device is fixed in a structure that is always unfolded, it can be very inconvenient to remove or store it. Therefore, to support the barrier plate, it must be structured to be unfolded and foldable when removing it after the situation is over, making it much more convenient not only for removal but also for storage. For this reason, the first and second auxiliary supports of the barrier plate support device are combined in a structure that can be rotatably folded. However, if it is a simple structure that unfolds and folds, the folding part may be forcibly folded due to water pressure or external impact, and if the device supporting the barrier plate folds unexpectedly in this way, the barrier plate will end up tipping over backward.

[0020] Therefore, in order to prevent the overturning of the blocking plate as described above, the part where the first auxiliary support and the second auxiliary support are rotatably connected can be fixed arbitrarily when necessary so that it does not fold even under external impact, and a device such as a folding prevention device having a predetermined length that can arbitrarily release the fixed state when it needs to be folded can be added.

[0021] <Fixed peg penetration hole of fixed body>

[0022] The blocking plate can be easily pushed by strong water pressure, and if pushed too far, the blocking plate cannot perform its function; therefore, a function to strongly support it is required to prevent it from being pushed easily. To prevent the blocking plate from being easily pushed backward, a first through hole must be formed in the fixed body to allow a fixing peg to be inserted into the ground, thereby strongly suppressing the blocking plate's sliding by inserting a sturdy fixing peg into the ground. Additionally, since the blocking plate has a wide surface area, it can easily be overturned by strong headwinds; therefore, a function to suppress overturning may also be necessary depending on the situation. This function is achieved by forming a second through hole in an 'X' shape with the first through hole, into which a fixing peg is inserted to counteract the force acting in the opposite direction to the fixing peg that supports it from being pushed by water pressure.

[0023] <Block plate support device handle>

[0024] Since the barrier plate support has a certain amount of weight, it is advisable to form a handle that allows for easy handling. Because there is a risk of injury from hands getting caught in the folding parts if the barrier plate support is handled incorrectly, it is recommended to form a handle on the upper front or rear surface of the device for easy handling.

[0025] <Block plate fastening hole of block plate support device>

[0026] In order to install a blocking plate or move the installed blocking plate to another location more conveniently, it is efficient to move the blocking plate and the blocking plate support device as a set unit, so it is preferable to form a blocking plate fastening hole through the upper front side of the connecting member so that the blocking plate and the blocking plate support device can be fixed with a bolt or the like so that they do not separate. Effects of the invention

[0027] The blocking plate support device of the present invention is primarily a device for infinitely connecting and supporting blocking plates in parallel. It is equipped with features for user convenience and safety, including an anti-slip spike function to prevent the blocking plates from being easily pushed by water pressure. As such, it not only enables effective connection and support of blocking plates but can also be usefully applied to various sites, such as supports for signboards controlling access to hazardous areas and supports for fences installed for facility protection.

Specific details for implementing the invention

[0029] Overview

[0030] In the present invention, the main purpose of the blocking plate support device (A-SD) is to connect and firmly support blocking plates (A) installed to block water or sediment flowing in due to heavy rain, floods, landslides, etc. The basic structure comprises a connecting member (B) that connects the blocking plates (A), a support member (100) that is rotatably coupled to the connecting member (B) to allow the blocking plates to be erected, an auxiliary support member (110) in which the other end of a first auxiliary support member (111) that is rotatably coupled to the connecting member (B) and the other end of a second auxiliary support member (112) are rotatably coupled, and a fixed body (200) into which the other end of the support member (100) is inserted and placed on the ground. The present invention proposes a blocking plate support device (A-SD) that can respond more efficiently to the above-mentioned situation by adding convenience and safety functions to this basic structure, and FIG. 4 is a comprehensive perspective view including the added functions.

[0031] The blocking plate support device (A-SD) can be configured as shown in FIG. 2, with one support member (100) in a single support type (2-1) and two support members in a double support type (2-2).

[0032] However, since the double support type (2-2) is superior to the single support type (2-1) in terms of support capacity and stability, the following explanation will be based on the double support type (2-2).

[0033] The barrier plate support device (A-SD) of the present invention is primarily used to support standard barrier plates as shown in 3-1 of FIG. 3, but it can also be applied to support non-standard barrier plates as shown in 3-2, as well as to support no-entry signs in dangerous areas such as road subsidence areas or cliffs as shown in 3-3, and to manage cargo in storage yards as shown in FIG. 3-4. Furthermore, it can be utilized in various fields, such as as a support for fences installed to protect facilities and property.

[0034] Therefore, the blocking plate support device (A-SD) of the present invention is most frequently used to block water or sediment flowing in due to floods, heavy rains, landslides, etc., and is named 'blocking plate support device' for convenience; however, it can be widely used for other purposes, and the name may be changed according to the intended use for easier understanding.

[0035] Unless otherwise specified, the definitions of terms in the present invention include 'pipe' meaning a hollow rod-shaped material, 'solid' meaning a solid rod-shaped material, and 'semicircle' meaning a mathematical concept of exactly half of a circle, but also include conceptual concepts that may be larger or smaller than half.

[0036] In addition, regarding the materials of the components in the present invention, the fixed body (200) is not limited to any one of the following: synthetic resin such as plastic or iron, but is preferably made of a strong material that does not easily break, and other elements may be more stable if they are made of a strong material such as iron or stainless steel that not only does not easily bend or break but can also be well joined by welding, etc.

[0037] In addition, since there is only one ‘pin’ among the components, the ‘fastening pin’ (113), the ‘pin’ and the ‘fastening pin’ are identical parts, so for convenience of explanation, the ‘fastening pin’ may be abbreviated as ‘pin’. Furthermore, among the terms used in the ‘cited invention’, the term ‘rotation’, which means ‘to rotate around an axis’, has been changed to ‘rotation’, in order to use the most common term in the dictionary.

[0038] The scope of the present invention is not limited to the embodiments described below, and various modifications may be made within the scope that does not deviate from the technical essence of the present invention.

[0039] Hereinafter, the blocking plate support device of the present invention will be described in detail with reference to the attached FIGS. 2 to 24. It is added that, in order to facilitate a better understanding of the device, the content includes not only the functions added according to the present invention but also the functions of the ‘cited invention’ that is the subject of the improved invention.

[0040] <Main Structure of the Folding Type>

[0041] As shown in FIG. 4, the main structure of the foldable method of the present invention (including the function of the cited invention) is provided with a support member (100) rotatably coupled to the upper part of the connecting member (B), a fixed body (200) into which the other end of the support member (100) is inserted and placed on the ground, a first auxiliary support member (111) rotatably coupled to the lower part of the connecting member (B), and the other end of the first auxiliary support member (111) and the other end of the second auxiliary support member (112) are rotatably coupled by a fastening pin (113).

[0042] In the shape of the auxiliary support (110), either the first auxiliary support (111) or the second auxiliary support (112) must be in the shape of a semicircular pipe that can wrap around the other. In FIG. 5-1, the first auxiliary support (111) is in the shape of a semicircular pipe, and in FIG. 5-2, the second auxiliary support (112) is in the shape of a semicircular pipe.

[0043] However, while one must be in the shape of a semicircular pipe, the other does not necessarily have to be in the shape of a circle or a solid. That is, if one is in the shape of a semicircular pipe, the other can be in the shape of a circle, a semicircular or solid pipe, and furthermore, as shown in 5-3 of FIG. 5, a polygon that is not circular or semicircular is also possible, so it is not necessary to be limited to any one shape or form.

[0044] In order for the blocking plate support device (A-SD) to be folded and unfolded, the support member (100) and the auxiliary support member (110) must be organically combined. Therefore, as shown in 4-2 of FIG. 4, one end of the first auxiliary support member (111) is connected to the rotation axis (111a) in a 'T' shape, the rotation axis (111a) is rotatably inserted into the rotation groove (111b), and the rotation groove (111b) must be fixed to the connecting member (B). Thus, the other end of the first auxiliary support member (111), which is rotatably connected to the connecting member (B) at one end, is rotatably connected to the other end of the second auxiliary support member (112), which is rotatably connected to the connecting member (100) in an 'A' shape and the support member (100) at one end in a 'T' shape, by means of a pin, the angle at which the support member (100) is unfolded by the auxiliary support member (110) is limited, and the support member (100) can function organically with the auxiliary support member (110).

[0045] <Fixture and Fixing Peg Penetration Hole>

[0046] The basic structure of the above-described fixed body (200) is as shown in FIG. 6, and its main function is not only to keep the blocking plate (A) upright by placing it on the ground with the other end of the support (100) inserted and fixed as shown in FIG. 7, but also to have the function of inserting a first fixing peg (11) to resist the blocking plate (A) from being pushed backward by water pressure, and to have the function of inserting a second fixing peg (12) to resist the blocking plate (A) from being flipped forward by reverse wind.

[0047] The blocking plate (A) can be easily pushed by strong water pressure, and if pushed too much, the blocking plate (A) will not be able to perform its function, so a function to strongly support it so that it is not easily pushed is required.

[0048] In order to prevent the blocking plate (A) from being easily pushed backward, a first through hole (220a) is formed in the fixed body (200) so that a fixing peg can be inserted into the ground as shown in FIG. 6. When a sturdy fixing peg is inserted into the ground, the pushing of the blocking plate (A) can be strongly suppressed. Since the first through hole (220a) is intended to respond to water pressure, it is formed horizontally (220a) so that the fixing peg (10) is vertical or the upper end of the fixing peg (11) is tilted toward the front as shown in FIG. 6 and FIG. 7.

[0049] In addition, since the blocking plate (A) has a wide surface area, it may flip forward in strong headwinds; therefore, to suppress such flipping, a second through hole (220b) can be formed so that the upper end of the fixing peg (10) is tilted toward the rear, as shown in 6-3 of FIG. 6, so that a fixing peg can be inserted to counteract the force acting in a direction corresponding to the headwind, as shown in 7-2 of FIG. 7.

[0050] One or more fixing peg through holes (220) formed in the fixing body (200) can be formed for each function. That is, one or more first fixing peg through holes (220a) can be formed, and one or more second fixing peg through holes (220b) can also be formed.

[0051] In addition, the inclination of the first fixed peg through hole (220a) does not necessarily have to match the indentation of the insertion groove (210) of the support (100). However, the inclination of the through hole (220a) can be set within a range that does not interfere with the support (100) when striking the fixed peg (11) to insert the first fixed peg (11) into the ground.

[0052] As described above, the method for responding to water pressure and backwind is illustrated in FIG. 7. Among the functions of the fixed pegs described above, the function of the first fixed peg (11, 220a) to resist being pushed by water pressure is an important component, but the function of the second fixed peg (12, 220b) to resist being overturned by backwind may be necessary, but is merely supplementary depending on the situation or site of application and is not an important component.

[0053] Spike that suppresses the jungle (600)

[0054] Since the installed blocking plate (A) may be pushed backward by strong water pressure, in order to support it, a sturdy fixing peg (11) that prevents pushing is inserted into the ground through a through hole (220a) formed in the fixing body (200), so that the blocking plate (A) can be stably maintained even under strong water pressure.

[0055] However, inserting the fixing peg (11) even in situations where the water pressure is weak enough that the blocking plate (A) is not pushed back with only slight resistance is not only inconvenient, but in cases where the fixing peg (11) is not inserted well on a hard surface such as asphalt or concrete, the blocking plate (A) or the blocking plate support device (A-SD) must be supported by a separate load instead of the fixing peg (11).

[0056] Therefore, in order to effectively respond to water pressure that is not easily pushed with only a certain amount of resistance, or to asphalt or concrete floors where the fixing peg (11) cannot be inserted, this problem can be solved by forming a spike on the bottom surface of the fixing body (200) that is not easily pushed by weak water pressure. Of course, the spike method would not be very effective if the floor were hard and smooth, as it would slide, but in the case of ordinary asphalt or concrete floors, the floor is not completely smooth and there are usually many gaps where a sharp spike can be inserted.

[0057] Therefore, if a spike (600) with multiple pointed needles protruding from the bottom surface of the fixed body (200) is formed, it can be said that there is a resistance that can suppress the sliding of the blocking plate (A) when the water pressure is not strong.

[0058] The above-described spike (600) can be implemented in various ways, such as fixing a plurality of pointed needles to a plate so that they face vertically or backward (the tips of the needles face backward), as shown in FIG. 8, or forming them integrally with the plate, and inserting them into the bottom surface of the fixing body (200) as a plate-shaped inside type (610) as shown in FIG. 9-1 and fastening them with adhesive or bolts, or wrapping the bottom part of the fixing body (200) as a box-shaped outside type (620) as shown in FIG. 9-2 and fastening them with bolts as shown in FIG. 10-1, or fixing them with adhesive as shown in FIG. 10-2.

[0059] In addition, the shape of the spike (600) is formed so that the lower end can be easily embedded in the ground and resist, and the material is made of a strong material that does not easily break even with impact, but it is not necessary to specify it.

[0060] In the case where the spike (600) that suppresses sliding is not provided, as shown in FIG. 11, the bottom surface of the fixed body (200) that touches the ground is in contact with the ground without much resistance and can be easily pushed by weak water pressure. However, when the above-mentioned spike (600) is provided, as shown in FIG. 12, the spike (600) with a plurality of sharp needles protruding from the bottom surface of the fixed body (200) resists in the opposite direction of sliding, so it is not easily pushed by weak water pressure.

[0061] <Folding safety handle (700)>

[0062] When folding the blocking plate support device (A-SD), the lower part (110ht) of the pin (113) connecting the first auxiliary support (111) and the second auxiliary support (112), which are unfolded in a '—' shape, is struck upward as shown in FIG. 13. During this process, as the unfolded auxiliary support (110) is folded into an 'Ʌ' shape, there is a risk of injury from a hand getting caught in the folding gap (110ht) as shown in 13-2 of FIG. 13. To prevent such safety accidents, a separate folding safety handle can be formed so as not to touch the folding part.

[0063] The above-mentioned safety handle can be implemented by extending the fastening pin (113) as shown in 14-1 of FIG. 14, or by forming a separate safety handle (700) as shown in FIG. 14-2.

[0064] However, if the pin (113) is extended to form a handle, as shown in 15-1 of FIG. 15, when the blocking plate support device (A-SD) is folded, the support (100) strikes (100a) the fastening pin (113), increasing the risk of the fastening pin (113) being damaged. Therefore, although possible, this may not be a desirable method.

[0065] In addition, if the connecting pin (113) is formed long and configured as a folding handle, when the blocking plate support device (A-SD) is folded, as shown in 15-1 of FIG. 15, the part (a) where the support (100) contacts the connecting pin (113) becomes the folding limit point (100a), so the auxiliary support (110) is not folded sufficiently, and the maximum folding angle (100aa) becomes large, causing inconvenience during removal and storage.

[0066] However, if a separate folding safety handle (700) is formed as shown in 14-2 of FIG. 14, when the blocking plate support device (A-SD) is folded as shown in 15-2 to 16 of FIG. 15, the support (100) strikes the first auxiliary support rotation groove (111b) (100b). However, since the rotation groove (111b) comes into contact with the first auxiliary support rotation axis (111a) and does not receive any impact, there is almost no risk of damage. Furthermore, as shown in 15-2 of FIG. 15, the part (b) where the support (100) comes into contact with the first auxiliary support rotation groove (111b) becomes the folding limit point (100b), so the auxiliary support (110) can be folded sufficiently, and the maximum folding angle (100ba) becomes smaller, making it more convenient to remove and store.

[0067] In addition, as shown in 16-2 of FIG. 16, even when the folding safety handle (720) is held by hand and folded to the folding limit point (100b), there is enough space in the handle space (700s) so that there is no risk of the hand getting caught. Accordingly, it is more efficient to form the folding safety handle (700) on the top of the first auxiliary support (111) as shown in FIG. 17.

[0068] In addition, the folding safety handle (700) can be implemented in various shapes as shown in FIG. 18, and since any of the methods from 18-1 to 18-3 in FIG. 18 has its own advantages and disadvantages, it is not necessary to be limited to any specific method.

[0069] <Folding prevention device (400)>

[0070] If the barrier plate support device is fixed in a fixed, unfolded state, it can be very inconvenient to move it to another location or store it. Therefore, the barrier plate support device (A-SD) must be a structure that can be folded and unfolded depending on the situation.

[0071] For this reason, the first auxiliary support (111) and the second auxiliary support (112) of the blocking plate support device are rotatably connected by a pin (113). However, if it is a simple structure that unfolds and folds, the folding part may be forcibly folded by water pressure or external impact, and if the auxiliary support (110) is folded by external impact in this way, the blocking plate (A) will end up flipping backward.

[0072] Therefore, in order to solve the problem where the auxiliary support (110) may be folded by an external impact and the blocking plate may be overturned as described above, the part where the first auxiliary support (111) and the second auxiliary support (112) are rotatably connected must be fixed as needed so as not to be folded by an external impact, and a separate device must be provided that can arbitrarily release the fixed state when it needs to be folded.

[0073] A device capable of satisfying the above needs is the anti-folding device (400) shown in FIG. 19. When the auxiliary support (110) of the anti-folding device (400) is unfolded and the guide portion (410) of the anti-folding device (400) is fastened to the fastening pin (113), the anti-folding device (400) is structurally not easily detached even by external impact, as shown in FIG. 21. However, to further enhance safety, the function of a fixing bolt (500) can be added as shown in 19-2 of FIG. 19 so that the first auxiliary support (111) and the second auxiliary support (112) can be maintained in a securely fixed state.

[0074] The above-mentioned anti-folding member (400) is in the form of a pipe, and its inner diameter is larger than the outer diameter of the auxiliary support (110). After the guide portion (410), which is recessed in an L-shape in the longitudinal direction, is fitted into the protruding part of the fastening pin (113), the anti-folding member (400) is rotated 90° so that the pin (113) comes into contact with the bent end of the guide portion (410) formed in an L-shape. As a result, the handle (420) of the anti-folding member (400) faces downward as shown in FIG. 4. Since the handle (420) has a certain amount of load, the anti-folding member (400) does not rotate easily and does not detach even with external impact.

[0075] If the auxiliary support (110) is fastened with a folding prevention device (400) as shown in 22-1 of FIG. 22 and is not fixed with a fixing bolt (500), the first auxiliary support (111) and the second auxiliary support (112) may fold slightly into the gap between them, but this does not significantly affect safety. Nevertheless, in order to ensure that the folding prevention device (400) does not detach from any external impact and can securely fix the auxiliary support (110), the handle (420) of the folding prevention device (400) is formed as a nut-type through hole. When necessary, as shown in 22-2 of FIG. 22, if the second auxiliary support (112) is pushed up with the fixing bolt (500), the first auxiliary support (111) and the second auxiliary support (112) rotate relative to each other by the gap between them and are compressed together to securely fix them.

[0076] However, for the guide portion (410) of the anti-folding member (400) to be detached from the pin (113) while fastened, it must be rotated 90° in a specific direction and then pushed in a specific direction. Therefore, since the anti-folding member (400) has structurally high fastening stability, the function of compressing with a fixing bolt (500) is not an essential element, but it may be applied differentially in order to pursue more perfect safety.

[0077] <Block plate support device handle (800)>

[0078] Since the blocking plate support device (A-SD) has a certain amount of weight, it is advisable to form a handle that allows for easy handling. If the blocking plate support device (A-SD) is mishandled, there is a risk of injury from the hand getting caught in the folding part. Therefore, it is advisable to form a handle (800) that allows for easy handling on the upper front or rear surface of the blocking plate support device (A-SD), as shown in FIG. 2 or 23-2 of FIG. 23. Furthermore, forming the handle (800) on the rear surface rather than the front surface may be more convenient for handling. Additionally, while the handle (800) can be secured by fastening with bolts, securing it by welding may be more robust. Moreover, the shape of the handle (800) can be implemented in various forms, such as a 'U' shape or a foldable shape.

[0079] <Block plate fastening hole (B101) of block plate support device>

[0080] In order to install the blocking plate (A) or to move the installed blocking plate (A) to another location more quickly as needed, it is advantageous if the blocking plate (A) and the blocking plate support device (A-SD) can be combined as a set. Therefore, as shown in 23-1 of FIG. 23, a blocking plate fastening hole (B101) is formed that penetrates from the upper front side to the rear side of the connecting member (B) so that the blocking plate (A) and the blocking plate support device (A-SD) can be fixed with bolts, etc., thereby allowing the blocking plate (A) and the blocking plate support device (A-SD) to be fixed with bolts, etc., through the fastening hole (B101) when necessary.

[0081] FIG. 24 is a rear view comparing the efficiency of moving equipment when a blocking plate fastening hole (B101) is formed and when it is not. When the blocking plate fastening hole (B101) is not formed, as shown in FIG. 24-1, the blocking plate (A) and the blocking plate support device (A-SD) are separated, so there is the inconvenience of having to handle them separately. However, when the blocking plate fastening hole (B101) is formed, as shown in FIG. 24-2, the blocking plate (A) and the blocking plate support device (A-SD) are fastened and fixed, so they can be handled as a set, making it fast and convenient. Industrial applicability

[0082] The blocking plate support device (A-SD) of the present invention can be easily applied in various fields, such as supporting a blocking plate to block the inflow of water or sediment caused by floods, landslides, etc., in addition to its primary use as a support for a sign prohibiting entry to dangerous areas, or supporting a simple fence installed to protect facilities. Furthermore, since it can be easily manufactured using conventional technology and equipment, its industrial applicability is excellent. Explanation of the symbols
