Abstract

The present invention provides a road structure that absorbs construction errors regarding the spacing length between the first and second posts, by including a plurality of posts that are fixed and spaced apart on both sides of the road in the left and right directions intersecting the front-rear direction of a vehicle, and a horizontal frame that is arranged in the left and right directions to traverse the road, wherein one side is inserted and fixed into a first through hole formed in a first post erected on one side of the road among the posts, and the other side is inserted and fixed into a second through hole formed in a second post erected on the other side of the road among the posts, and the length in the left and right directions is formed to be longer than the spacing length between the first post and the second post, and because the horizontal frame is fixed after being inserted in a state movable in the left and right directions through the first through hole and the second through hole. Therefore, since the horizontal frame is inserted into the through hole formed in the support so that it can move left and right, it is fixed, which allows for the efficient absorption of construction errors regarding the spacing between the supports, thereby offering the advantage of improved construction convenience.

Description

Technology Field

[0001] The present invention relates to a road structure, and more specifically, to a road structure with improved construction convenience. Background Technology

[0002] Generally, tunnels are constructed by penetrating obstacles such as mountains to facilitate rapid passage on highways. While these tunnels offer the significant advantage of shortening travel times by minimizing vehicle mileage, they present a disadvantage in that it is difficult to respond quickly to various accidents occurring inside. In particular, in the event of a fire caused by a traffic accident or electrical short circuit, there is a high risk of suffocation from flames or smoke. Furthermore, if a driver enters the tunnel without realizing the accident, rapid evacuation may not be possible, raising concerns about large-scale human and material damage.

[0003] Accordingly, a device is installed and operated at the tunnel entrance that automatically displays the accident situation externally and blocks vehicle entry in the event of a disaster inside the tunnel. Conventional devices for blocking tunnel entry utilize a flange connection method for the truss structure.

[0004] However, this flange connection method presents a problem where construction becomes difficult if the truss structure does not correspond to the length between the spaced supports. Therefore, conventionally, when installing devices to block tunnel entry, a loose connection is used instead of a full connection when joining the supports. This allows the supports to swing from side to side, after which the truss structure is joined and a full connection is performed.

[0005] However, with this method, there is a limit to the range of sway the posts can undergo—that is, the range through which construction errors can be absorbed. Therefore, if the length of the truss structure exceeds this tolerance, the construction must be reworked. Additionally, because the road surface where the posts are installed is not flat, it is difficult to accurately align the height levels; consequently, there is a risk that the structure may need to be reworked to achieve the correct height.

[0006] Republic of Korea Registered Patent No. 10-1448581 The problem to be solved

[0007] The present invention aims to provide a road structure in which construction convenience is improved by forming a through hole in the support column that can absorb construction errors. means of solving the problem

[0008] According to one aspect of the present invention, the present invention provides a road structure that absorbs a construction error regarding the spacing length between the first and second posts, by including a plurality of posts that are fixed and spaced apart on both sides of the left and right directions of a road that intersects with the front-rear direction in which a vehicle travels, and a horizontal frame that is arranged in the left and right directions to traverse the road, wherein one side is inserted and fixed into a first through hole formed in a first post erected on one side of the road among the posts, and the other side is inserted and fixed into a second through hole formed in a second post erected on the other side of the road among the posts, and the length in the left and right directions is formed to be longer than the spacing length between the first post and the second post, and the horizontal frame is fixed after being inserted in a state movable in the left and right directions through the first through hole and the second through hole. Effects of the invention

[0009] The road structure according to the present invention has the following effects.

[0010] First, since the horizontal frame is inserted into the through hole formed in the support so that it can move left and right, and then fixed, it can efficiently absorb construction errors regarding the spacing length between the supports, which has the advantage of improving construction convenience.

[0011] Second, the through holes formed in the supports extend vertically, and since the horizontal frame is inserted into the through holes in a state where it can move vertically and then fixed, it can efficiently absorb construction errors caused by height differences in the roads where the supports are erected, which has the advantage of improving construction convenience.

[0012] Third, since the worker steps up to fasten the truss after it has been seated on the support and has been positioned accurately through free movement left and right, it has the advantage of preventing accidents such as the worker's hand being caught or pinched between the truss and the support.

[0014] The present invention will be described in detail below by explaining preferred embodiments of the invention with reference to the attached drawings.

[0015] Referring to FIGS. 1 through 8, a road structure (1000) according to one embodiment of the present invention includes a support (1100), a horizontal frame (1200), a message display module (1300), a height adjustment device (1400), a support fixing module (1500), and a lifting device (1600). The road structure (1000) according to this embodiment is installed on a road where vehicles travel and serves to enable the installation of advertising boards for product advertisements, guide signs that provide information on road conditions, or road cameras that monitor traffic volume. When the road structure (1000) is installed at the entrance of a tunnel, it can serve to display messages that convey information to drivers about the conditions inside the tunnel. In this case, the road structure (1000) is installed to be erected on the tunnel entrance road.

[0016] A plurality of posts (1100) are fixed spaced apart on both the left and right sides of the road that intersect with the front and rear directions in which the vehicle travels. The posts (1100) fixed on both sides of the road in the left and right directions are installed so as to stand upright and face each other. A through hole is formed in the upper part of the posts (1100) in the left and right directions.

[0017] The support post (1100) includes a first support post (1110) and a second support post (1120). The first support post (1110) is erected on one side (center of the road) in the left-right direction of the road. The first support post (1110) includes a first-1 support post (1111) and a first-2 support post (1112). The first-1 support post (1111) and the first-2 support post (1112) are arranged to be spaced apart along the front-back direction. Since the first-1 support post (1111) and the first-2 support post (1112) are similar to the second-1 support post (1121) described below, a detailed description is omitted.

[0018] The second support (1120) is erected on the other side (the edge of the road) in the left and right directions of the road. The second support (1120) includes a second-1 support (1121) and a second-2 support (1122). The second-1 support (1121) and the second-2 support (1122) are arranged to be spaced apart along the front and back directions. The second-1 support (1121) is arranged to face the first-1 support (1111) along the left and right directions, and the second-2 support (1122) is arranged to face the first-2 support (1112) along the left and right directions. That is, if the first-1 support (1111) and the first-2 support (1112) and the second-1 support (1121) and the second-2 support (1122) are connected by an imaginary straight line, they form a rectangular shape.

[0019] Since the 2-1 support post (1121) and the 2-2 support post (1122) have similar shapes and structures, the 2-1 support post (1121) is described in detail, and the 2-2 support post (1122) is omitted. The 2-1 support post (1121) includes a 2-1 support post body (1121a), a 2-1 support post cover (1121b), and a 2-1 support post auxiliary unit (1121c). The 2-1 support post body (1121a) is erected at the edge of the road. The second-1 support body (1121a) is extended downward from the upper part where the second through hole (1121a1), which is a second through hole formed in the second-1 support body (1121a), is opened, to a position spaced apart by a second set length so as to adjust the height in the vertical direction of the inserted horizontal frame (1200).

[0020] In addition, among the 2-1 support posts (1121), the 2-1 front upper fastening hole (1121a2) and the 2-1 front lower fastening hole (1121a4) are formed on the front side of the portion where the 2-1 through hole (1121a1) is formed, and the 2-1 rear upper fastening hole (1121a3) and the 2-1 rear lower fastening hole (1121a5) are formed on the rear side. The 2-1 front upper fastening hole (1121a2) is formed in the front direction on the front side facing the upper portion of the 2-1 through hole (1121a1). Furthermore, the 2-1 front upper fastening hole (1121a2) is extended by a set length in the vertical direction.

[0021] And the second-1 rear upper fastening hole (1121a3) is formed in the front-rear direction on the rear side facing the upper part of the second-1 through hole (1121a1). The second-1 rear upper fastening hole (1121a3) is extended in the vertical direction by a set length while facing the second-1 front upper fastening hole (1121a2). The length to which the second-1 rear upper fastening hole (1121a3) is extended in the vertical direction is the same as the length to which the second-1 front upper fastening hole (1121a2) is extended in the vertical direction.

[0022] The second-1 front lower fastening hole (1121a4) is formed in the front side facing the lower part of the second-1 through hole (1121a1) in the aforementioned front-rear direction. That is, the second-1 front lower fastening hole (1121a4) is formed at a position spaced downward from the second-1 front upper fastening hole (1121a2). Furthermore, the second-1 front lower fastening hole (1121a4) is extended by a set length in the aforementioned up-down direction.

[0023] And the second-1 rear lower fastening hole (1121a5) is formed in the front-rear direction on the rear side facing the lower part of the second-1 through hole (1121a1). The second-1 rear lower fastening hole (1121a5) is extended in the vertical direction by a set length while facing the second-1 front lower fastening hole (1121a3). The length to which the second-1 rear lower fastening hole (1121a5) is extended in the vertical direction is the same as the length to which the second-1 rear upper fastening hole (1121a3) is extended in the vertical direction.

[0024] The second-1 front lower fastening hole (1121a4) and the second-1 rear lower fastening hole (1121a5) each serve to provide a clearance space (construction error absorption space) that allows movement in the up-and-down direction when the second lower fixing bolt, which will be described below, is inserted. Additionally, the second-1 front upper fastening hole (1121a2) and the second-1 rear upper fastening hole (1121a3) each serve to provide a clearance space (construction error absorption space) that allows movement in the up-and-down direction when a second upper fixing bolt, similar to the second lower fixing bolt, is inserted.

[0025] The second-1 support cover (1121b) is detachably coupled to the upper part of the second-1 support body (1121a) which is open. In this embodiment, the second-1 support cover (1121b) is bolted to the second-1 support body (1121a) as an example, but the method of coupling the second-1 support cover (1121b) to the second-1 support body (1121a) can be changed. Furthermore, unless otherwise specified, when two members are coupled, the two members are bolted to each other. The second-1 support cover (1121b) has a circular plate structure. The second-1 support cover (1121b) serves to open and close the upper part of the second-1 support body (1121a).

[0026] The second-1 support auxiliary unit (1121c) includes a second-1 support auxiliary unit front part (1121c1), a second-1 support auxiliary unit rear part (1121c2), and a second-1 support auxiliary unit middle part (1121c3). The second-1 support auxiliary unit front part (1121c1) has a plate shape extending in the vertical direction. The second-1 support auxiliary unit front part (1121c1) serves to close and flatten the curved portion formed on the inner surface of the front side of the second-1 support (1121) by being integrally connected and fixed to both ends of the inner surface of the front side of the second-1 support (1121). That is, the front side portion (1121c1) of the second-1 support member is structured similarly to a chord connecting two points of the front side portion in the circular cross-section of the second-1 support member (1121) extended in the vertical direction. Additionally, a second-1 support member front side auxiliary unit fastening hole (1121c1') is formed in the front side portion (1121c1) of the second-1 support member in the vertical direction so as to face the second-1 front side upper fastening hole (1121a2) and the second-2 front side lower fastening hole (1121a4), respectively. At this time, the second-1 support member front side auxiliary unit fastening hole (1121c1') is extended integrally in the vertical direction.

[0027] The rear portion (1121c2) of the second-1 support auxiliary unit has a plate shape that extends in the vertical direction. The rear portion (1121c2) of the second-1 support auxiliary unit is integrally connected and fixed to both ends of the inner surface of the rear side of the second-1 support (1121), thereby serving to close and flatten the curved portion formed on the inner surface of the rear side of the second-1 support (1121). That is, the rear portion (1121c2) of the second-1 support auxiliary unit has a structure similar to a chord extending in the vertical direction from two points of the rear portion in the circular cross-section of the second-1 support (1121). In addition, on the rear portion (1121c2) of the second-1 support auxiliary unit, a second-1 support rear auxiliary unit fastening hole (1121c2') is formed in the front-rear direction so as to face the second-1 rear upper fastening hole (1121a3) and the second-2 rear lower fastening hole (1121a5), respectively. At this time, the second-1 support rear auxiliary unit fastening hole (1121c2') is integrally extended in the upper-lower direction.

[0028] Furthermore, the middle section (1121c3) of the second-1 support unit is integrally connected to the lower end of the front section (1121c1) of the second-1 support unit, and the rear section is integrally connected to the lower end of the rear section (1121c2) of the second-1 support unit. At this time, the middle section (1121c3) of the second-1 support unit has a downwardly convex shape. Also, the front section (1121c1) of the second-1 support unit and the rear section (1121c2) of the second-1 support unit are formed in a symmetrical structure centered on the middle section (1121c3) of the second-1 support unit. That is, the second-1 support unit (1121c) is formed in a structure similar to a '∪' overall.

[0029] The horizontal frame (1200) is positioned in the left and right directions to cross the road. One side of the horizontal frame (1200) is inserted and fixed into a first through hole formed in a first support post (1110) erected on one side of the road among the support posts (1100), and the other side is inserted and fixed into a second through hole (1121a1) formed in a second support post (1120) erected on the other side of the road among the support posts (1100). The horizontal frame (1200) is formed such that the length in the left and right directions is longer than the distance between the first support post (1110) and the second support post (1120).

[0030] This is because the horizontal frame (1200) is fixed after being inserted in a state where it can move in the left and right directions through the first through hole and the second through hole (1121a1), thereby absorbing construction errors regarding the spacing length between the first support (1110) and the second support (1120). In addition, the first through hole formed in the first support (1110) is extended by a first set length in the vertical direction, and the second through hole (1121a1) formed in the second support (1120) is extended by a second set length in the vertical direction. In this embodiment, the first set length and the second set length are exemplified as being the same, but the first set length and the second set length can be changed. At this time, since the horizontal frame (1200) is fixed after being inserted in a state where it can move in the vertical direction through the first through hole and the second through hole (1121a1), it can also absorb construction errors regarding the height difference of the road where the first support (1110) and the second support (1120) are erected.

[0031] The horizontal frame (1200) includes a front upper horizontal bar (1210), a front lower horizontal bar (1220), a rear upper horizontal bar (1230), a rear lower horizontal bar (1240), and a horizontal frame bridge bar (1250). One side of the front upper horizontal bar (1210) is inserted into the upper part of the first through hole formed in the first-1 support (1111), and the other side is inserted into the upper part of the second through hole formed in the second-1 support (1121). Then, one side of the front lower horizontal bar (1220) is inserted into the lower part of the first through hole formed in the first-1 support (1111), and the other side is inserted into the lower part of the second through hole (1121a1) formed in the second-1 support (1121).

[0032] And one side of the rear upper horizontal bar (1230) is inserted into the upper part of the first through hole formed in the first-2 support (1112), and the other side is inserted into the upper part of the second through hole formed in the second-2 support (1122). And one side of the rear lower horizontal bar (1240) is inserted into the lower part of the first through hole formed in the first-2 support (1112), and the other side is inserted into the lower part of the second through hole formed in the second-2 support (1122).

[0033] Since the front upper horizontal bar (1210), front lower horizontal bar (1220), rear upper horizontal bar (1230), and rear lower horizontal bar (1240) each have a similar structure, the front lower horizontal bar (1220) will be described in detail below, and the detailed description of the remaining horizontal bars will be omitted. The front lower horizontal bar (1220) has a cylindrical shape that extends in the left and right directions to be positioned across the road, and has a hollow formed inside.

[0034] The other side of the front lower horizontal bar (1220) is inserted into the 2-1 through hole (1121a1) from top to bottom through the open upper portion of the 2-1 support body (1121a) while the 2-1 support cover (1121b) is separated from the 2-1 support body (1121a). And one side of the front lower horizontal bar (1220), although not specifically shown in the drawing, is inserted into the 1-1 through hole, which is the 1-1 through hole formed in the 1-1 support (1111), from top to bottom through the open upper portion of the 1-1 support body while the 1-1 support cover is separated from the 1-1 support body.

[0035] At this time, the second-1 support cover (1121b) is connected to the open upper portion of the second-1 support body (1121a) while the other side of the front lower horizontal bar (1220) is inserted into the second-1 through hole (1121a1), thereby closing the upper portion of the second-1 support cover (1121b). Additionally, the first-1 support cover is connected to the open upper portion of the first-1 support body while the other side of the front lower horizontal bar (1220) is inserted into the first-1 through hole, thereby closing the upper portion of the first-1 support cover.

[0036] In addition, a front lower horizontal bar (1220) has a front fastening hole (1220a) and a rear fastening hole (1220b) formed therein. The front fastening hole (1220a) is formed in the front side facing the inner surface of the second-1 support (1121) in the aforementioned front-rear direction. The rear fastening hole (1220b) is formed in the rear side facing the inner surface of the second-1 support (1121) in the aforementioned front-rear direction.

[0037] At this time, the front lower horizontal bar front fastening hole (1220a) and the front lower horizontal bar rear fastening hole (1220b) are each extended in the left and right directions, so that when the second lower fixing bolt described below is inserted in the front and back directions, the front lower horizontal bar (1220) moves in the left and right directions, the second lower fixing bolt can be inserted in a spare space (construction error absorption space).

[0038] Just as a front lower horizontal bar front fastening hole (1220a) and a rear lower horizontal bar rear fastening hole (1220b) are formed in the front lower horizontal bar (1220), a rear lower horizontal bar front fastening hole and a rear lower horizontal bar rear fastening hole are also formed in the rear lower horizontal bar (1240). Accordingly, the second lower fixing bolt can be connected by penetrating the front lower horizontal bar (1220) and the rear lower horizontal bar (1220).

[0039] The horizontal frame bridge bar (1250) reinforces the rigidity of the horizontal frame (1200) by connecting the front upper horizontal bar (1210), the front lower horizontal bar (1220), the rear upper horizontal bar (1230), and the rear lower horizontal bar (1240) to each other. Multiple horizontal frame bridge bars (1250) are integrated and arranged on the front upper horizontal bar (1210), the front lower horizontal bar (1220), the rear upper horizontal bar (1230), and the rear lower horizontal bar (1240) respectively so that a truss structure is formed on the horizontal frame (1200).

[0040] The message display module (1300) includes a horizontal rail module (1310) and a message providing module (1320). The horizontal rail module (1310) is coupled to a horizontal frame (1200) and is positioned in the left and right directions to traverse the road. The horizontal rail module (1310) provides a path along which a message display member (1323) displaying a guide message or an advertisement message can move.

[0041] The horizontal rail module (1310) includes a rail support bar (1311) and a rail section (1312). The rail support bar (1311) is integrally connected to the lower surface of the horizontal frame (1200). The horizontal rail module (1310) extends in the front-rear direction and protrudes further forward than the front end of the horizontal frame (1200). Additionally, a plurality of horizontal rail modules (1310) are arranged spaced apart along the left-right direction.

[0042] The rail section (1312) is spaced apart and positioned on the front side of the horizontal frame (1200). The rail section (1312) is seated on the rail support bars (1311) and connected integrally. The rail section (1312) is positioned in the left and right directions to cross the road, thereby providing a path for the message display member (1323) to move along the left and right directions.

[0043] The message providing module (1320) includes a case (1321), a sliding unit (1322), and a message display member (1323). The case (1321) is coupled to the second-1 support (1121). However, the present invention is not limited thereto and the position where the case (1321) is coupled can be changed.

[0044] And the case (1321) has a receiving space formed inside to store the message display member (1323). The receiving space of the case (1321) is formed to be equal to or longer than the vertical length of the message display member (1323) so that the message display member (1323) can be maintained in a state where it is unfolded in the vertical direction. And the part of the case (1321) facing the first support (1111) is formed to be open or have a structure that can be opened and closed.

[0045] The upper part of the sliding unit (1322) is coupled to the rail portion (1321) so that it can slide in the left and right directions on the rail portion (1312). The lower part of the sliding unit (1322) is coupled to the upper part of a message display member (1323) placed in the receiving space of the case (1321), so that the message display member (1323) slides along the rail portion (1312) to unfold or fold.

[0046] The message display member (1323) has one upper side connected to the lower side of the sliding unit (1322), so that when the sliding unit (1322) slides in the direction of the first-1 support (1111), the one upper side is pulled and moved in the direction of the first-1 support (1111) and unfolds. Then, when the sliding unit (1322) returns to the direction of the second-1 support (1121) while in the state of having moved in the direction of the first-1 support (1111), the one upper side of the message display member (1323) is pulled and moved in the direction of the second-1 support (1121) and folds.

[0047] The height adjustment device (1400) includes a first-1 height adjustment device (not shown) coupled to a first-1 support (1111), a first-2 height adjustment device (not shown) coupled to a first-2 support (1112), a second-1 height adjustment device (1400A) coupled to a second-1 support (1121), and a second-2 height adjustment device (1400B) coupled to a second-2 support (1122). Since each of the first-1 height adjustment device, the first-2 height adjustment device, and the second-2 height adjustment device (1400B) is similar to the second-1 height adjustment device (1400A), the second-1 height adjustment device (1400A) will be described in detail below.

[0048] The 2-1 height adjustment device (1400A) adjusts the installation height by allowing the front lower horizontal bar (1220) to move up and down while the front lower horizontal bar (1220) is inserted into the 2-1 through hole (1121a1). When the front lower horizontal bar (1220) is positioned at the location where installation is required, the 2-1 height adjustment device (1400A) fixes the front lower horizontal bar (1220).

[0049] The second-1 height adjustment device (1400A) includes a second-1 height adjustment fixed module (1410) and a second-1 height adjustment moving module (1420). The second-1 height adjustment fixed module (1410) is integrally connected and fixed at a position adjacent to the second-1 through hole (1121a1) among the second-1 supports (1121). The front lower horizontal bar (1220) of the second-1 height adjustment fixed module (1410) provides a second-1 height adjustment path that allows it to move in the vertical direction.

[0050] The 2-1 height adjustment fixing module (1410) includes a 2-1 lower fixing unit (1411), a 2-1 upper front fixing unit (1412), a 2-1 upper rear fixing unit (1413), a 2-1 middle front fixing unit (1414), and a 2-2 middle rear fixing unit (1415). The 2-1 lower fixing unit (1411) is coupled to a position spaced downward from the lower end of the 2-1 through hole (1121a1) on the outer side opposite the inner side facing the 1-1 support (1111). The 2-1 lower fixing unit (1411) is extended and protrudes away from the 1-1 support (1111) and has a plate shape.

[0051] The second-1 upper front fixing unit (1412) is coupled to a position on the outer side of the second-1 support (1121) at a position spaced upward from the lower end of the second-1 through hole (1121a1) by a set length.

[0085] The height adjustment device (2400) includes a first height adjustment device (not shown) coupled to a first support (2110) and a second height adjustment device (2400) coupled to a second support (2120). In this embodiment, the first height adjustment device and the second height adjustment device (2400) are similar to the second-1 height adjustment device (1400A) among the road structures (1000) according to FIGS. 1 to 8, so a detailed description is omitted.

[0086] That is, the road structure (2000) according to the present embodiment differs from the road structure (1000) according to FIGS. 1 to 8 in that the first support (1110) and the second support (1120) are paired and consist of two of each, in that the first support (2110) and the second support (2120) are each included only one of each. Therefore, the road structure (2000) according to the present embodiment has a difference in that the support fixing module for connecting the first-1 support (1111) and the first-2 support (1112) arranged in pairs in the front-rear direction in the road structure (1000) according to FIGS. 1 to 8, and the support fixing module (1520) for connecting the second-1 support (1121) and the second-2 support (1122) arranged in pairs in the front-rear direction are unnecessary.

[0087] In addition, unlike the road structure (1000) according to FIGS. 1 to 8, where two horizontal bars are arranged vertically spaced apart on the front and rear sides, only two horizontal frames (2200) are arranged vertically spaced apart. That is, while the horizontal frame (1200) in the road structure (1000) according to FIGS. 1 to 8 has a rectangular shape, the horizontal frame (2200) in this embodiment has a rectangular planar shape.

[0088] And the road structure (2000) according to the present embodiment does not include the message display module (1300) of the road structure (1000) according to FIGS. 1 to 8, and displays a guidance message directly on the horizontal frame (2200) or support (2100) or installs a camera, etc.

[0089] That is, the road structure (2000) according to the present embodiment has the advantage of being easy to install because its configuration is simplified compared to the road structure (1000) according to FIGS. 1 to 8. In addition, the horizontal frame (2200) is formed in a planar shape such as a rectangle, so the load is reduced, and compared to a structure having a rectangular shape, the surface viewed by the driver has the same cross-sectional area, so there is no problem at all in installing various facilities such as billboards, signposts, or cameras.
