Description

{Prefabricated foundation structure for large LED signboard}

The present invention relates to an assembly-type foundation structure for supporting a large LED display board, and more particularly, to an assembly-type foundation structure for supporting a large LED display board including a plurality of foundation blocks that are laminated and assembled in a stepped pyramid shape.

In general, LED display boards are widely used in the form of signs that provide information such as vehicle speed limits, variable road conditions, etc., and outdoor billboards that provide commercial advertisements and other information.

Recently, LED display boards for commercial advertising are becoming larger in order to accurately convey information and maximize advertising effects. These large LED display boards are increasingly being utilized in various fields such as advertising, information transmission, and entertainment, and their performance and functions are continuously improving as technology advances.

Among these LED display boards, those that are installed on the ground are installed using supports. In the past, in order to securely install the supports on the ground, a deep groove was first dug into the ground, a support was placed in the groove, and concrete mortar was poured to securely install the support.

This method, starting with the concrete mixing process, formwork installation process, pouring of the mixed concrete, and curing process, is carried out directly on site, so it takes a lot of time for each process and, depending on the environment, the work time is unnecessarily delayed.

Accordingly, although work has been recently being carried out by manufacturing the foundation concrete in advance and then burying it in the desired location, this conventional foundation concrete has a structure that can be applied to the supports of small facilities such as small LED display boards, traffic lights, street lights, or surveillance cameras, and has had limitations in supporting and fixing the supports of large facilities with large loads such as large LED display boards.

The background technology of this invention is disclosed in registered patent No. 10-1311259.

The technical problem to be solved by the present invention is to provide a prefabricated foundation structure for a large LED display board support, which not only improves structural stability by firmly supporting and fixing the support of a large facility such as a large LED display board, but also enables on-site prefabricated installation without the concrete pouring and curing processes, thereby shortening the installation period, and has uniform strength and quality.

The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

FIG. 2 is a cross-sectional view for explaining an assembly-type foundation structure for supporting a large LED display board according to embodiments of the present invention.

Referring to FIGS. 1 to 5, a prefabricated foundation structure (100) for a large LED display board support according to embodiments of the present invention is a structure for fixing a support (20) of a large LED display board, such as a road display board (Variable Message Sign: VMS), by being buried in a trench (10) formed at a predetermined depth in the ground, and may include a plurality of foundation blocks (110, 120, 130) that are laminated and assembled in a stepped pyramid shape.

As an example of a large LED display board, variable message signs (VMS) are equipment that provide road users with real-time information on traffic volume, traffic accidents, congested sections, weather conditions, and construction-related controls, thereby improving traffic flow efficiency and safety.

In the present invention, a plurality of foundation blocks (110, 120, 130) are concrete structures formed using a mold, and can safely transfer the load of the support itself and the load acting on the support to the ground. Each of the plurality of foundation blocks (110, 120, 130) is pre-manufactured to have uniform mechanical properties (e.g., compressive strength), size, weight, etc. according to required quality standards, and may generally have a hexahedral shape of a square pillar, but the present invention is not limited thereto. The plurality of foundation blocks (110, 120, 130) may be selected to have an appropriate shape, such as a cylinder or an octagonal pillar, depending on the size of the large LED display board or the location where it is to be installed.

According to embodiments of the present invention, a plurality of base blocks (110, 120, 130) may be stacked in a stepped pyramid shape with a size (e.g., an area of an upper surface or lower surface) that gradually increases upward.

For example, the plurality of foundation blocks (110, 120, 130) may include a lower foundation block (110) that is settled on the bottom surface of the excavation groove (10), an upper foundation block (130) to which the lower end of a large LED display board support (20) is fixedly connected, and at least one interlayer foundation block (120) that is interposed between the lower foundation block (110) and the upper foundation block (130). At this time, the interlayer foundation block (120) has a smaller top area (i.e., the area of the top surface) than the lower foundation block (110) and is laminated on the lower foundation block (110) so as to expose an edge portion of the top surface of the lower foundation block (110), and the upper foundation block (130) has a smaller top area than the interlayer foundation block (120) and is laminated on the interlayer foundation block (120) so as to expose an edge portion of the top surface of the interlayer foundation block (120). Additionally, for structural stability, it may be desirable for the plurality of foundation blocks (110, 120, 130) to have substantially the same height (i.e., the same thickness) as each other. That is, the thicknesses (t1, t2, t3) of the plurality of foundation blocks (110, 120, 130) may be the same as each other.

In FIGS. 1 to 3, one interlayer foundation block (120) is illustrated as being interposed between the lower foundation block (110) and the upper foundation block (130), but the present invention is not limited thereto. Depending on the scale (e.g., size, load, etc.) of the large LED display board or the installation location, two or more interlayer foundation blocks (120) may be interposed between the lower foundation block (110) and the upper foundation block (130).

Additionally, a plurality of base blocks (110, 120, 130) can be formed into a structure that can be assembled by assembling adjacent base blocks.

For example, the lower foundation block (110) may include lower central grooves (111) formed at a certain depth from its first upper surface (110a) toward its first lower surface (110b), lower insertion grooves (112) formed on its first upper surface (110a), lower anchor grooves (113) formed at a certain depth from its first upper surface (110a) toward its first lower surface (110b), and lower protrusions (114) protruding downward from its first lower surface (110b), and the interlayer foundation block (120) may include interlayer central holes (121) penetrating its second upper surface (120a) and its second lower surface (120b), interlayer anchor bolts (122) embedded inside and protruding onto its second lower surface (120b), interlayer protrusions (123) protruding downward from its second lower surface (120b), and interlayer insertion grooves (112) formed on its second upper surface (120a). It may include interlayer insertion grooves (124) and interlayer anchor grooves (125) formed at a certain depth from the second upper surface (120a) toward the second lower surface (120b).

When the interlayer foundation block (120) is laminated on the lower foundation block (110), the interlayer protrusions (123) are inserted to engage with the lower insertion grooves (112), and the interlayer anchor bolts (122) are inserted into the lower anchor grooves (113) into which a chemical adhesive (CA) is injected so that they can be assembled.

Specifically, when the lower foundation block (110) is settled within the blasting groove (10), a chemical adhesive (CA) can be injected into the lower anchor grooves (113).

The lower protrusions (114) are formed integrally with the lower foundation block (110) and can serve to firmly fix the lower foundation block (110) that is settled on the bottom surface of the excavation groove (10) to the ground. In order to improve the fixing force, the lower protrusions (114) can be formed spaced apart along the horizontal and vertical directions of the lower foundation block (110) to form a plurality of rows and columns, as shown in FIG. 4.

Since the chemical adhesive (CA) can be any known chemical adhesive used in general chemical anchors, a detailed description thereof will be omitted.

Interlayer anchor bolts (122) are inserted into lower anchor grooves (113) into which chemical adhesive (CA) is injected, and interlayer foundation blocks (120) can be laminated on the lower foundation block (110) so that interlayer protrusions (123) are inserted into the lower insertion grooves (112). Thereafter, as the chemical adhesive (CA) hardens, the interlayer anchor bolts (122) are fixed, so that the interlayer foundation blocks (120) can be laminated and assembled on the lower foundation block (110).

As the interlayer protrusions (123) are inserted into the lower insertion grooves (112) and interlock with each other, the resistance to external pressure in the lateral direction is improved, so that the lower foundation block (110) and the interlayer foundation block (120) can be more firmly joined.

Next, an upper foundation block (130) can be laminated and assembled on the interlayer foundation block (120).

For example, the upper foundation block (130) may include upper central holes (131) penetrating its third upper surface (130a) and third lower surface (130b), upper anchor bolts (132) embedded therein and protruding onto the third lower surface (130b), and upper protrusions (133) protruding from the third lower surface (130b), and when the upper foundation block (130) is laminated on the interlayer foundation block (120), the upper protrusions (133) are inserted to engage with the interlayer insertion grooves (124), and the upper anchor bolts (132) are inserted into the interlayer anchor grooves (125) into which a chemical adhesive (CA) is injected, so that the two blocks can be laminated and assembled in a prefabricated manner.

That is, after the interlayer foundation block (120) is laminated and bonded on the lower foundation block (110), a chemical adhesive (CA) is injected into the interlayer anchor grooves (125), and the upper anchor bolts (132) are inserted into the interlayer anchor grooves (125) into which the chemical adhesive (CA) is injected, and the upper foundation block (130) can be laminated on the interlayer foundation block (120) so that the upper protrusions (133) are inserted into the interlayer insertion grooves (124). Thereafter, as the chemical adhesive (CA) hardens, the upper anchor bolts (132) are fixed, so that the upper foundation block (130) can be laminated and bonded in a prefabricated manner on the interlayer foundation block (120).

The resistance to external pressure in the lateral direction is improved by interlocking the upper protrusions (133) with each other through the interlayer insertion grooves (124), so that the upper foundation block (130) and the interlayer foundation block (120) can be more firmly joined.

Meanwhile, on the side walls of each of the lower foundation block (110), the inter-floor foundation block (120), and the upper foundation block (130), lifting hook fastening grooves (110c, 120c, 130c) may be provided, to which lifting hooks for moving the respective foundation blocks (110, 120, 130) are fastened in a hooking manner, and the lifting hooks fastened to the lifting hook fastening grooves (110c, 120c, 130c) may be used to move the respective foundation blocks (110, 120, 130) and sequentially stack them on the bottom surface of the excavation groove (10).

Each of the lifting ring fastening grooves (110c, 120c, 130c) may have a shape in which a portion of the side wall of each of the foundation blocks (110, 120, 130) is recessed inward and bent upward. In addition, the lifting ring fastening grooves (110c, 120c, 130c) may be formed in a line shape surrounding the side walls of each of the foundation blocks (110, 120, 130), and thereby the lifting rings for moving the foundation blocks (110, 120, 130) may be easily fastened to the lifting ring fastening grooves (110c, 120c, 130c).

According to the concept of the present invention, the lower foundation block (110), the interlayer foundation block (120) and the upper foundation block (130) can be stacked so that corresponding ones among the lower central grooves (111), the interlayer central holes (121) and the upper central holes (131) of each of the foundation blocks (110, 120, 130) are vertically connected, and thus, central fastening grooves (CH) can be formed inside the stacked foundation blocks (110, 120, 130).

A chemical adhesive (CA) may be injected into the central fastening grooves (CH) formed in the laminated foundation blocks (110, 120, 130), and central anchor bolts (CB) may be inserted into the central fastening grooves (CH) into which the chemical adhesive (CA) has been injected. Thereafter, as the chemical adhesive (CA) hardens, the central anchor bolts (CB) are fixed, so that the lower foundation block (110), the interlayer foundation block (120), and the upper foundation block (130) may be vertically joined more firmly.

In addition, the central anchor bolts (CB) inserted into the central fastening grooves (CH) can protrude above the first upper surface (110a) of the upper foundation block (130), and the lower part of the large LED signboard support (20) can be fixedly connected to the upper part of the central anchor bolts (CB) protruding above the first upper surface (110a) of the upper foundation block (130).

Although not included in the city, wire holes for inserting power lines for supplying power to a large LED display board installed on a pillar (20) and/or communication cables for controlling the large LED display board can be formed to be connected within each of the foundation blocks (110, 120, 130).

According to the concept of the present invention, the central anchor bolts (CB) and central fastening grooves (CH), upper anchor bolts (132) and interlayer anchor grooves (125), upper projections (133) and interlayer insertion grooves (124), interlayer anchor bolts (122) and lower anchor grooves (113), and interlayer projections (123) and lower insertion grooves (112) that are assembled together can be implemented to maximize the strengthening of the bonding force and the improvement of structural stability between the stacked foundation blocks (110, 120, 130).

According to one embodiment, as illustrated in FIG. 5, the central fastening grooves (CH) and the central anchor bolts (CB) that are inserted and coupled to each other in a planar view may be arranged at regular intervals along the circumferential direction in the central portions of the stacked foundation blocks (110, 120, 130). In addition, the interlayer insertion grooves (124) and the upper protrusions (133) that are inserted and coupled to each other may be arranged spaced apart from each other along the edge of the upper foundation block (130) to form a square ring shape, and the lower insertion grooves (112) and the interlayer protrusions (123) that are inserted and coupled to each other may be arranged spaced apart from each other along the edge of the interlayer foundation block (120) to form a square ring shape. And, the interlayer anchor grooves (125) and upper anchor bolts (132) inserted and connected to each other can be spaced apart in a ring shape between the interlayer insertion grooves (124) and the central fastening grooves (CH) to surround the central fastening grooves (CH), and the lower anchor grooves (113) and interlayer anchor bolts (122) inserted and connected to each other can be spaced apart in a ring shape between the lower insertion grooves (112) and the interlayer anchor grooves (125) to surround the interlayer anchor grooves (125).

In addition, the depth (h2) of the interlayer anchor grooves (125) (i.e., the length from the second upper surface (120a) of the interlayer foundation block (120) to the lowermost end of the interlayer anchor grooves (125)) may be 1/2 to 3/4 of the thickness (t2) of the interlayer foundation block (120), and the depth (h11) of the lower anchor grooves (113) (i.e., the length from the first upper surface (110a) of the lower foundation block (110) to the lowermost end of the lower anchor grooves (113)) may be 1/2 to 3/4 of the thickness (t1) of the lower foundation block (110). Furthermore, it may be preferable that the depth (h12) of the lower central grooves (111) forming the lower portions of the central fastening grooves (CH) and the depth (h11) of the lower anchor grooves (113) are the same.

In addition, the depth (124h) of the interlayer insertion grooves (124) (i.e., the length from the second upper surface (120a) of the interlayer foundation block (120) to the lowermost end of the interlayer insertion grooves (124)) may be 1/10 to 1/5 of the thickness (t2) of the interlayer foundation block (120), and the depth (112h) of the lower insertion grooves (112) (i.e., the length from the first upper surface (110a) of the lower foundation block (110) to the lowermost end of the lower insertion grooves (112)) may be 1/10 to 1/5 of the thickness (t1) of the lower foundation block (110).

In the same manner as described above, the lower foundation block (110), the inter-floor foundation block (120), and the upper foundation block (130) are assembled and laminated in a prefabricated manner within the excavated groove (10) to install the prefabricated foundation structure (100) for supporting a large LED display board. Then, the remaining space in the excavated groove (10) is filled in with soil or the like, thereby completing the construction of the prefabricated foundation structure (100) for supporting a large LED display board.

In general, when installing a support (20) for a large facility such as a large LED display board, it is necessary to form a deeper and wider trench (10) than a groove for a small LED display board, streetlight, traffic light, etc. In this case, when installing a support (20) for a large LED display board through a general concrete mortar pouring and curing process, a long curing process is required, which increases the construction time and thus causes inconvenience in that the control of vehicles on site is also prolonged. In addition, there is a limitation that a support (20) for a large LED display board cannot be installed in the winter because curing is impossible.

To improve these problems, a method can be used in which foundation concrete is manufactured in advance, placed in a trench (10), and a support for a large LED display board is installed. However, it is not easy to manufacture large-sized foundation concrete of 2 to 3 m or more in width, length, and/or height with the required strength and quality, and heavy equipment is required to transport and install it, making construction difficult.

However, according to embodiments of the present invention, a plurality of prefabricated foundation blocks (110, 120, 130) manufactured in advance according to required quality standards (e.g., uniform mechanical properties, size, weight, etc.) are laminated and assembled in a stepped pyramid shape to install a prefabricated foundation structure (100) for a large LED display board support, thereby facilitating construction and installation, shortening the installation time, and increasing structural stability.

In addition, since construction and installation are possible even in winter, and the on-site construction process is simplified, installation of a large LED display board can be possible on the same day as the installation of the prefabricated foundation structure (100) for the large LED display board support, and there is an advantage in that the surrounding control time (e.g., vehicle control on the road) due to the installation of a large LED display board can be minimized.

Fig. 6 is a cross-sectional view illustrating a structure in which a plurality of interlayer foundation blocks are laminated between a lower foundation block and an upper foundation block. In this drawing, two interlayer foundation blocks are illustrated, but the present invention is not limited thereto. For simplicity of explanation, detailed descriptions of overlapping configurations are omitted.

The plurality of interlayer foundation blocks may have the same structure and may be laminated and connected in a prefabricated manner, but may have a top area that gradually decreases as it goes up. In addition, the interlayer foundation block of the lowest layer among the plurality of interlayer foundation blocks may be prefabricated and connected with the lower foundation block (110), and the interlayer foundation block of the highest layer among the plurality of interlayer foundation blocks may be prefabricated and connected with the upper foundation block (130).

Specifically, referring to FIG. 6, the prefabricated foundation structure (100) for supporting a large LED display board may include a lower foundation block (110), a first inter-layer foundation block (120_1), a second inter-layer foundation block (120_2), and an upper foundation block (130) that are laminated and assembled in a stepped pyramid shape. The lower foundation block (110) may have substantially the same structure as the lower foundation block (110) of FIGS. 1 to 3, and the upper foundation block (130) may have substantially the same structure as the upper foundation block (130) of FIGS. 1 to 3. In addition, each of the first and second inter-layer foundation blocks (120_1, 120_2) may have substantially the same structure as the inter-layer foundation block (120) of FIGS. 1 to 3. At this time, the second inter-floor foundation block (120_2) may have a smaller surface area than the first inter-floor foundation block (120_1).

In the present embodiment, the prefabricated laminated joining method between the plurality of foundation blocks (110, 120_1, 120_2, 130) may be substantially the same as described with reference to FIGS. 1 to 5. That is, the prefabricated laminated joining method between the upper foundation block (130) and the second inter-floor foundation block (120_2) may be substantially the same as the prefabricated laminated joining method between the upper foundation block (130) and the inter-floor foundation block (120) described with reference to FIGS. 1 to 5, and the prefabricated laminated joining method between the lower foundation block (110) and the first inter-floor foundation block (120_1) may be substantially the same as the prefabricated laminated joining method between the lower foundation block (110) and the first inter-floor foundation block (120_1) described with reference to FIGS. 1 to 5.

Meanwhile, the first interlayer foundation block (120_1) and the second interlayer foundation block (120_2) can be assembled by being inserted so that the interlayer protrusions (123_2) of the second interlayer foundation block (120_2) are engaged with the interlayer insertion grooves of the first interlayer foundation block (120_1), and the interlayer anchor bolts (122_2) of the second interlayer foundation block (120_2) are inserted into the interlayer anchor grooves of the first interlayer foundation block (120_1) into which a chemical adhesive (CA) is injected.

And, corresponding ones of the lower central grooves (111), the inter-floor central holes and the upper central holes (131) of each of the lower foundation block (110), the plurality of inter-floor foundation blocks (120_1, 120_2) and the upper foundation block (130) are vertically connected to form central fastening grooves (CH) inside the stacked foundation blocks (110, 120, 130), and central anchor bolts (CB) are inserted into the central fastening grooves (CH) into which a chemical adhesive (CA) is injected, so that the lower foundation block (110), the plurality of inter-floor foundation blocks (120_1, 120_2) and the upper foundation block (130) can be vertically connected more firmly.

Although the embodiments of the present invention have been described with reference to the attached drawings, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical idea or essential features thereof. Therefore, it should be understood that the embodiments and application examples described above are exemplary in all respects and are not restrictive.
