Description

Technology Field

[0001] The present invention relates to a safety structure installed to prevent people or vehicles from veering off or falling on roads, walking paths, pedestrian walkways, bridges, riverbanks, etc. Background Technology

[0002] Wood Plastic Composite, which generally possesses a texture and appearance similar to natural wood, consists of micron-sized wood particles completely surrounded by polyolefin polymers, making it highly resistant to moisture. As a new concept material that combines the advantages of both wood and polymers through the bonding of natural wood and polymers, it is currently widely used as an interior and exterior building material.

[0003] The above synthetic wood is a type of standardized manufactured product, so it is easy to install. Compared to general treated wood or wood materials, it does not require separate painting or maintenance, does not deform, is harmless to the human body and the environment, does not require preservative treatment like treated wood, so there is no environmental pollution caused by it, and is an eco-friendly material that can be reused and reprocessed. It also has excellent heat resistance, tensile strength, and bending strength, and has almost no moisture absorption, so it is a material that can be used in natural exposed conditions or in places with a lot of moisture.

[0004] Accordingly, fences and railings—structures used to mark deck roads, park gardens, and boundaries between sidewalks and roadways, protect facilities, prevent external intrusion, and prevent pedestrians or cyclists from falling off the road or pedestrians from crossing the road illegally—are being constructed using the aforementioned synthetic wood, which possesses various advantages. Recently, design fences featuring diverse shapes and colors that enhance aesthetic appeal are being manufactured and used to ensure that fences harmonize with the surrounding environment while maintaining their original functions, such as boundary marking and prevention of external intrusion.

[0005] As for prior art related to a design-type fence manufactured using synthetic wood in this manner, the applicant of the present invention's previously registered invention, "Patent Registration No. 2022286, Title / Design-type fence with excellent protective performance," is proposed.

[0006] The aforementioned prior art provides an effect that prevents damage to the fence and offers excellent protective performance by maintaining sufficient rigidity to withstand horizontal loads applied to composite wood posts fitted on the outside of the outer metal square tube, through which an inner metal square tube integrated with a fixed base plate is installed in a double layer inside an outer metal square tube, and a reinforcing core fixed to the inner metal square tube is in close contact with the inner surface of the outer metal square tube.

[0007] However, conventional fences or railings including the aforementioned prior art have problems that require the provision of separate fixed brackets, as well as reduced constructability and increased labor and material costs, when installed in curved or sloping sections, as fixed brackets must be attached to both sides of the posts and the movable lumber socket attached to the tip of the horizontal lumber must be connected to the fixed brackets and pivot bolts to ensure the movability (horizontal, vertical) of the horizontal lumber.

[0008] Furthermore, even though metal reinforcement is inserted inside the composite wood posts to reinforce strength, the aforementioned posts lack sufficient rigidity to withstand collisions with vehicles, etc., resulting in a problem of reduced safety and durability as fences. The problem to be solved

[0009] The present invention is intended to solve the problems of the prior art as described above, and,

[0010] The primary purpose is to provide a safety structure that facilitates construction even in sections with continuous topographical changes, such as curved and sloped sections, without the need for additional components like fixed brackets or movable sockets, and simplifies the construction process to resolve issues of reduced constructability and increased labor and material costs.

[0011] In addition, another objective of the present invention is to provide a safety structure capable of improving safety and protective performance as a fence or railing by fundamentally improving the strength limit of the support structure so as to ensure sufficient rigidity and durability against external forces such as vehicle collisions. means of solving the problem

[0012] In order to solve the above-mentioned problem, the present invention,

[0013] First, a direction-selectable connection part is formed on the support side to selectively switch the connection direction of a horizontal bar connected to a support fixedly installed on the ground or deck road, and by applying a movable horizontal bar socket to the tip of the horizontal bar connected to the direction-selectable connection part, the angle of the horizontal bar can be adjusted in the up-down and left-right directions.

[0014] Second, the present invention forms the direction-selectable connecting part into a vertical and horizontal coupling structure so as to correspond to inclined and curved sections, respectively, thereby allowing the angle of the horizontal bar to be selectively adjusted according to the coupling direction of the horizontal bar socket.

[0015] Third, by forming the connectors for the support posts and horizontal bars into an integrated casting structure and simultaneously implementing the bolt connection structure in a shape suitable for casting, structural strength and constructability can be secured simultaneously without additional processing steps. Effects of the invention

[0016] According to the present invention, by forming a direction-selectable connecting part on the support side that can selectively switch the connection direction of the horizontal bar and applying a movable horizontal bar socket to the tip of the horizontal bar, the angle of the horizontal bar can be adjusted in the up-down and left-right directions, thereby enabling the safety structure to be easily constructed even in inclined and curved sections without separate brackets or additional parts.

[0017] In particular, the present invention separately forms a connection groove for a vertical inclined section and a connection groove for a horizontal curved section in the direction-selectable connection part, and configures the angle of the horizontal bar to be selectively adjusted according to the connection direction of the horizontal bar socket; thereby, unlike conventional structures where the support post and the horizontal bar are fixedly connected and angle adjustment is impossible, stable installation is possible even in sections where terrain changes occur continuously.

[0018] Furthermore, in the present invention, by forming the reinforcing rib on the first horizontal bar connector with a width smaller than the width of the connector, the necessary rigidity can be secured without structurally hindering the vertical and horizontal rotation of the movable horizontal bar socket. This is based on a design concept that cannot be derived from a structure in which the reinforcing rib is formed with a uniform width, as in the prior art, which does not allow rotation of the horizontal bar, and thus provides an effect that goes beyond simple dimensional changes or conventional design modifications.

[0019] Furthermore, the present invention improves structural strength by integrally casting the support post and the connector for the crossbar, while configuring the bolt coupling hole communicating with the direction-selectable connection part as an elongated hole shape cut to the outer tip, thereby eliminating on-site drilling or additional processing steps that were inevitably required in conventional cast structures due to the difficulty of forming circular bolt holes. Accordingly, the manufacturing process is simplified, constructability is improved, and manufacturing and construction costs are reduced.

[0020] Furthermore, the angle of the horizontal bar can be adjusted and connection stability is ensured through the aforementioned elongated bolt connection hole and pivot bolt connection structure, thereby improving the reliability and durability of the safety structure even in the event of a vehicle collision or external force.

[0021] In summary, the present invention fundamentally overcomes the limitations of conventional support and fixed connection structures, which made it impossible to derive any technical feasibility for constructing inclined and curved sections, and provides a significant effect of simultaneously improving constructability, structural stability, and manufacturing efficiency.

Specific details for implementing the invention

[0023] We will now describe a preferred embodiment for more specifically implementing the means for solving the problem that the present invention aims to solve.

[0024] When looking at the overall configuration of the safety structure according to the first preferred embodiment of the present invention in the attached drawings, it can be seen that it is broadly divided into components such as a support (10), a pair of first horizontal bar connectors (20), a plurality of second horizontal bar connectors (30), a first horizontal bar (40), and a second horizontal bar (50).

[0025] Hereinafter, the present invention, composed of the above-mentioned general configuration, will be described in more detail to facilitate implementation.

[0026] The safety structure according to the present invention is a structure configured to be easily installed in response to inclined and curved sections, and can be applied to various places where people or vehicles pass, such as roads, walking paths, pedestrian walkways, bridges, and riverbanks, and can be applied to safety facilities in the form of fences, railings, etc.

[0027] The safety structure according to the present invention includes a support post (10) that is fixedly installed on a deck road or the ground using a fixed base (11) formed at the bottom, and is structured such that a first horizontal bar connector (20) and a first horizontal bar (40) are coupled around the support post (10), and a second horizontal bar connector (30) and a second horizontal bar (50) are coupled. In particular, the present invention is configured so that the angles of the first horizontal bar (40) and the second horizontal bar (50) can be selectively adjusted in the up-down and left-right directions by means of the mutual coupling relationship between the direction-selectable connecting part (21)(31) formed on the support post (10) and the movable horizontal bar socket (41)(51) coupled to the tip of the first horizontal bar (40) and the second horizontal bar (50).

[0028] A connecting rib (12) is formed on the upper part of the above-mentioned support (10), and a pair of first horizontal bar connectors (20) connected vertically via the connecting rib (12) are arranged.

[0029] Additionally, a central rib (13) is connected between the lower end of the first horizontal bar connector (20) positioned at the bottom and the fixed base (11), and a plurality of second horizontal bar connectors (30) are formed protruding from both sides of the central rib (13). Accordingly, a structure is formed in which the first horizontal bar (40) and the second horizontal bar (50) can be arranged in stages across the upper and middle / lower parts of the support column (10).

[0030] The first horizontal bar connector (20) has a '+' shaped direction-selecting connection part (21) formed through both sides, and a movable horizontal bar socket (41) coupled to the tip of the first horizontal bar (40) is fitted and coupled to both sides of the direction-selecting connection part (21).

[0031] In addition, the connector (30) for the second horizontal bar has a '+' shaped direction-selecting connection part (31) formed through both sides, and a movable horizontal bar socket (51) coupled to the tip of the second horizontal bar (50) is fitted and coupled to both sides of the direction-selecting connection part (31).

[0032] With this basic configuration, the present invention structurally secures the degree of freedom of connection between the support post (10), the first horizontal bar (40), and the second horizontal bar (50), thereby forming a base structure that can selectively respond to inclined sections and curved sections.

[0033] Here, the present invention incorporates a technology that ensures smooth rotation of a movable horizontal bar socket (41) coupled to a first horizontal bar connector (20) through the structure of a reinforcing rib (14).

[0034] To this end, a reinforcing rib (14) is formed at the front and rear ends of the connecting rib (12) in each of the pair of first horizontal bar connectors (20). At this time, the reinforcing rib (14) is formed with a width smaller than the total width of the first horizontal bar connector (20) as shown in FIG. 4.

[0035] Accordingly, while the structural rigidity of the first horizontal bar connector (20) itself is secured, the vertical and horizontal rotation of the movable horizontal bar socket (41) coupled to the first horizontal bar connector (20) is not structurally hindered.

[0036] This is clearly distinguished from the conventional structure in which the reinforcing rib (14) is formed to be the same as the connector width, thereby restricting the rotation of the first horizontal bar (40), and serves as an important structural prerequisite for enabling the construction of inclined and curved sections in the present invention.

[0038] The direction-selectable connecting part (21)(31) of the present invention is formed by dividing the connecting groove (22)(32) for the inclined section formed in the vertical direction and the connecting groove (23)(33) for the curved section formed in the horizontal direction.

[0039] That is, the structure has a configuration that allows the connection direction of the first horizontal bar (40) and the second horizontal bar (50) to be selectively switched within the same direction-selectable connection part (21)(31), thereby allowing different construction methods to be applied depending on terrain conditions.

[0040] This structure allows for both inclined and curved sections to be accommodated using only one direction-selectable connection part (21)(31) without using a separate dedicated bracket or additional parts.

[0041] When examining the connection and operation relationship in the inclined section according to the present invention, when a safety structure is installed in the inclined section, the inclined section connection groove (22)(32) among the direction-selectable connection parts (21)(31) is used. At this time, the connecting piece (42)(52) of the movable horizontal bar socket (41)(51) coupled to the tip of the first horizontal bar (40) and the second horizontal bar (50) is fitted into the inclined section connection groove (22)(32) in an upright state as shown in FIG. 8.

[0042] As a result of this combination, the angles of the first horizontal bar (40) and the second horizontal bar (50) can be adjusted in the vertical direction relative to the support (10). Accordingly, the first horizontal bar (40) and the second horizontal bar (50) can be naturally arranged along the slope of the terrain even in sloped sections where changes in ground elevation occur continuously.

[0043] As a result, the problem of difficulty in constructing the inclined section due to the inability to adjust the angle of the first horizontal bar (40) as in the past can be resolved, and stable construction on the inclined section is possible without a separate fixing bracket or additional parts.

[0044] In addition, regarding the connection and operation relationship in the inclined section according to the present invention, when a safety structure is installed in the inclined section, the connecting groove (23)(33) for the curved section among the direction-selecting connecting parts (21)(31) is used. At this time, the connecting piece (42)(52) of the movable horizontal bar socket (41)(51) coupled to the tip of the first horizontal bar (40) and the second horizontal bar (50) is fitted into the connecting groove (23)(33) for the curved section in a lying position as shown in FIG. 9.

[0045] As a result of this combination, the angles of the first horizontal bar (40) and the second horizontal bar (50) can be adjusted in the horizontal direction with respect to the support (10). Accordingly, the first horizontal bar (40) and the second horizontal bar (50) can be continuously arranged along the curvature of the curved section.

[0046] In other words, unlike conventional methods, there is no need to install additional movable brackets or rotating parts for curved section construction; instead, curved section construction is possible simply by combining the same direction-selectable connecting part (21)(31) and the movable horizontal bar socket (41)(51).

[0047] Meanwhile, the first horizontal bar connector (20) and the second horizontal bar connector (30) of the present invention are formed by integral casting with the support (10). Accordingly, compared to a conventional structure in which multiple parts are assembled, a decrease in strength at the joint can be prevented, and structural stability is improved even when external force is applied.

[0048] In addition, four bolt connection holes (24) (34) are formed on both sides of the outer surface of the first horizontal bar connector (20) and the second horizontal bar connector (30), respectively, communicating with the inclined section connection groove (22) (32) and the curved section connection groove (23) (33), respectively, and these bolt connection holes (24) (34) are characterized by being formed in the shape of elongated holes that are cut to the tip of the outer surface. Accordingly, a bolt connection structure can be realized solely by casting, thereby providing the effect of eliminating the need for on-site drilling or additional processing steps.

[0049] Here, in the connecting grooves (22)(32) for the inclined section and the connecting grooves (23)(33) for the curved section of the present invention, as shown in FIG. 11, a cushioning pad (25) is attached to each side with a bolt coupling hole (24)(34) in between, and this cushioning pad (25) absorbs the shock caused by excessive rotation when the movable horizontal bar socket (41)(51) made of synthetic resin rotates, thereby preventing damage to the movable horizontal bar socket (41)(51) and improving durability.

[0050] In addition, the rotational end position of the movable horizontal bar socket (41)(51) is gently limited by the above-mentioned cushioning pad (25), thereby preventing abrupt changes in the angle of the first horizontal bar (40) and the second horizontal bar (50), and thus improving operational stability during the construction process.

[0051] In addition, the cushioning pad (25) disperses and absorbs impact energy even when external shock or vibration is transmitted through the first horizontal bar (40) and the second horizontal bar (50), thereby relieving stress concentrated in the connecting grooves (22)(32) for inclined sections and connecting grooves (23)(33) for curved sections formed in the support (10) and extending the durability life of the entire structure.

[0052] Meanwhile, in the present invention, when the pivot bolt (60) is coupled by penetrating the bolt coupling hole (24)(34) in a horizontal or vertical direction, it is coupled by penetrating the connecting piece (42)(52) of the movable horizontal bar socket (41)(51) together, and a cap nut (61) is screw-coupled to the tip of the pivot bolt (60). With such a pivot coupling structure, the angle of the first horizontal bar (40) and the second horizontal bar (50) can be adjusted, and the coupled state is maintained stably, and even when an external force is applied, the coupling between the first horizontal bar (40) and the second horizontal bar (50) and the support (10) is prevented.

[0053] In this way, the components defined in each claim of the present invention operate organically with one another, enabling selective response to different terrain conditions, such as sloped sections and curved sections, based on the same basic structure.

[0054] As a result, the effects of improved constructability, ensured structural stability, and simplified manufacturing and construction processes are simultaneously realized, and the reliability and usability as a safety structure in various installation environments are significantly enhanced.
