Description

Technical Field

[0001] This invention relates to the field of municipal and infrastructure projects, and more specifically to a prefabricated guardrail. Background Technology

[0002] In recent years, with the continuous development of my country's economy, municipal and infrastructure construction has also been gradually improved. In particular, roads and supporting projects are increasing, and various facilities and equipment are becoming more numerous. During the construction process, often influenced by traditional manufacturing, products like guardrails are mostly semi-finished products that undergo secondary on-site processing. This involves using independent posts and railings, connecting the railings and posts with screws to form the guardrail. While this type of guardrail is easy to install, it occupies a large volume and space when reused, making storage and transportation inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide a prefabricated guardrail that uses an integrated assembly process, enabling rapid installation, disassembly, and self-adjustment of the guardrail, thus improving its practicality and greatly accelerating the construction progress.

[0004] To achieve the above objectives, the present invention provides a prefabricated guardrail, comprising at least two spaced-apart base devices, on which post devices are detachably mounted, and at least one connecting device connecting adjacent post devices, the connecting device being a telescopic structure; the base device includes a base column, limiting openings, and spring plates, the base column having a hollow portion for inserting the post device, and at least three limiting openings symmetrically formed along the circumferential direction on the peripheral wall of the hollow portion of the base column, and a spring plate retractable relative to the limiting openings being arranged at the sum of the limiting openings; the post device is inserted into the base column, and the post device is provided with a telescopic and rotatable limiting device at the position corresponding to the limiting opening and the spring plate, during installation, the limiting device can extend into the limiting opening and abut against the spring plate to compress it, thereby installing the post device in the base column.

[0005] Preferably, a positioning mark is provided on the top end face of the foundation column, and the positioning mark is located on the end face directly above the limiting port.

[0006] Preferably, the column device includes a protective column, a limit switch, a transmission rod, and a limiting device. The protective column is a columnar structure with a hollow section. The limit switch is located at the top of the protective column. The transmission rod passes through the hollow section of the protective column. The limiting device is located near the bottom of the protective column. During installation, the limiting device corresponds to the spring plate. Both ends of the transmission rod are connected to the limit switch and the limiting device, respectively. The limit switch controls the rotation of the transmission rod by forward / reverse rotation, causing the limiting device to extend or retract relative to the limiting opening. A first limiting structure and a second limiting structure are provided between the limit switch and the protective column. The first limiting structure limits the horizontal displacement of the limit switch, and the second limiting structure limits the rotation angle of the limit switch.

[0007] Preferably, the limiting device includes a rotating assembly and a limiting rod. The limiting rod is inserted through the column body of the protective column at a position corresponding to the spring plate. The rotating assembly is located in the hollow part of the protective column and is sleeved and fixed on the transmission rod. During installation, the limiting switch rotates, causing the transmission rod to rotate with the rotating assembly. During rotation, the rotating assembly can abut against the limiting rod, driving the limiting rod to extend into the limiting opening and compress the spring plate to achieve installation positioning. When disassembly is required, the limiting switch reverses. As the rotating assembly reverses, the abutting force against the limiting rod decreases, and under the elastic force of the spring plate, the limiting rod disengages from the limiting opening.

[0008] Preferably, the rotating component includes a plurality of fan-shaped structures evenly distributed along the circumference, with one fan-shaped structure corresponding to one limiting rod, and the same side of each fan-shaped structure is set as an arc-shaped surface structure with the same curvature.

[0009] Preferably, a support structure for supporting the conductive rod is provided at the bottom end of the protective column.

[0010] Preferably, the connecting device includes at least two external rods and one internal rod, the internal rod being located between the two external rods, and both ends of the internal rod passing through one end of the external rod located at its two ends; a length adjustment device is provided at the end where the internal rod and the external rod pass through.

[0011] Preferably, the column assembly and connecting device can be modularly assembled according to different needs.

[0012] The prefabricated guardrail of this invention disassembles traditional guardrails into standardized components. Through quick-positioning assembly, and with guardrail posts and connecting devices of different modules, the guardrail can be quickly installed and dismantled, and its length can be adjusted automatically. This improves the practicality of the guardrail, greatly speeds up the construction progress, and allows for disassembly and reuse without taking up much space, making it convenient for storage and transportation.

Detailed Implementation

[0021] The prefabricated guardrail of the present invention is characterized by comprising at least two spaced-apart base devices, on which column devices are detachably mounted, and at least one connecting device connecting two adjacent column devices, the connecting device being a telescopic structure; the base device comprises a base column, a limiting port, and a spring plate, the base column having a hollow portion for inserting the column device, at least three limiting ports symmetrically opened along the circumferential direction on the peripheral wall of the hollow portion of the base column, and a spring plate that can extend and retract relative to the limiting ports being arranged at the sum of the limiting ports; the column device is inserted into the base column, and the column device is provided with a telescopic and rotatable limiting device at the position corresponding to the limiting port and the spring plate, during installation, the limiting device can extend into the limiting port and abut against the spring plate to compress it, thereby installing the column device in the base column.

[0022] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings, but this is not intended to limit the invention.

[0023] Prefabricated guardrails, see Figures 1 to 7 It includes a foundation device 1, a column device 2, and a connecting device 3. The foundation device 1 is connected to the column device 2, and the two ends of the connecting device 3 are connected to the column device 2.

[0024] Basic device 1, see Figures 2 to 3 The system includes a foundation column 11, positioning markers 12, limiting openings 13, and a spring plate 14. The foundation column 11 serves as the column foundation and has a ring-shaped structure with a hollow section. Several limiting openings 13 are symmetrically and evenly distributed along the circumference of the foundation column 11, with the openings of the limiting openings 13 facing the center of the foundation column 11. A spring is fixedly installed within each limiting opening 13, and a plate-like structure forming a spring plate 14 is fixedly connected to the side of the spring facing the center of the limiting opening 13. The spring plate 14 can extend and retract within the limiting openings 13. The positioning markers 12 are located on the top end face of the foundation column 11, directly opposite the limiting openings 13, and are used to correct the column's installation orientation.

[0025] Column assembly 2, see Figures 4 to 6The system includes a protective post 21, a limit switch 22, a transmission rod 23, and a limiting device 24. The limiting device 24 includes a rotating assembly 242 and a limiting rod 243. The protective post 21 serves as the vertical support for the guardrail and is a columnar structure with a hollow section. The limit switch 22 is located at the top of the protective post 21, and the limiting device 24 is located near the bottom of the protective post 21. The transmission rod 23 passes through the hollow section of the protective post 21, its top end is fixedly connected to the limit switch 22, and its lower end passes through the limiting device 24 and is rotatably supported at the bottom of the protective post 21. The limit switch 22 has a cross-shaped handle located at the top of the protective post. To ensure the stability of the limit switch 22, a first limiting structure, such as a protrusion, is provided at the handle of the limit switch 22, so that the limiting protrusion of the cross-shaped handle of the limit switch is engaged with the outer or inner side of the protective post, preventing the limit switch 22 from shifting horizontally. A positioning structure for starting and stopping rotation in both forward and reverse directions is provided on the top end face of the protective column 21. For example, a positioning hole for the initial position and a positioning hole for the stop position after rotating a certain angle are opened on the top end face of the protective column 21. A positioning hole is also opened on the limit switch 22. When installing, the limit switch 22 is rotated from the initial position to the stop position. The pin passes through the positioning holes of the limit switch 22 and the protective column 21 to form a second limit structure to limit the end position of the limit switch 22. When reversing, the pin is removed, the limit switch 22 is rotated from the stop position to the initial position, and then the pin passes through the positioning holes of the limit switch 22 and the protective column 21 to position the limit switch 22 at the initial position.

[0026] A plurality of limiting rods 243 are evenly arranged along the circumference of the side wall near the bottom of the protective column 21, with each limiting rod 243 corresponding to a limiting opening 13. A limiting protrusion is provided at the end of the limiting rod 243 facing the conducting rod 23 to prevent the limiting rod 243 from falling off the protective column 21, and the end of the limiting rod 243 facing the limiting opening 13 is set with an arc-shaped end face. A rotating assembly 242 is sleeved on the conducting rod 23 and fixed by a pin. The rotating assembly 242 includes a sleeve 245 and a plurality of fan-shaped structures 244 of a certain thickness evenly arranged along the circumference of the sleeve 245, the number of fan-shaped structures being the same as the number of limiting rods 243. The same side of each fan-shaped structure of the rotating assembly 242 is set with an arc-shaped surface structure, and the end of the limiting rod 243 facing the conducting rod 23 contacts the arc-shaped surface structure of the fan-shaped structure 244. The sleeve 245 of the rotating assembly 242 is fitted onto the transmission rod 23 and fixed to the transmission rod 23 by a pin. In the initial position, the end of the limiting rod 243 facing the limiting port 13 is located in the protective column 21.

[0027] Connection device 3, see Figure 1 and Figure 7The device includes an inner connecting rod 32 and outer connecting rods 31 located at both ends of the inner connecting rod 32. The two ends of the inner connecting rod 32 are respectively inserted into the outer connecting rods 31 at both ends to form a connecting device 3. The outer connecting rods 31 at both ends of the inner connecting rod 32 are respectively connected to the column devices 2 located at both ends of the connecting device 3 by screws. The outer connecting rods 31 and the inner connecting rod 32 are hollow tubular structures. Several positioning holes are spaced apart along the length direction at the adjacent ends of the outer connecting rods 31 and the inner connecting rod 32. An elastic protrusion 321 is provided at each end of the inner connecting rod 32. The elastic protrusion 321 can be formed by an elastic sheet with a protrusion at one end. The elastic sheet is located in the hollow part of the inner connecting rod 32. A through hole is opened on the inner connecting rod 32. Under the action of elastic force, the protrusion on the elastic sheet passes through the through hole of the inner connecting rod 32 and protrudes from the outer surface of the inner connecting rod 32 to form the elastic protrusion 321. When both ends of the inner connecting rod 32 are inserted into the outer connecting rod 31, the elastic protrusion 321 can be placed in any of the positioning holes on the outer connecting rod 31, passing through the positioning holes and protruding from the outer surface of the outer connecting rod 31, thus positioning the inner connecting rod 32. By placing the elastic protrusion 321 on the inner connecting rod 32 in different positioning holes, the total distance the inner connecting rod 32 extends into the outer connecting rod 31 can be adjusted, thereby adjusting the length of the connecting device 3. During disassembly, the elastic protrusion 321 is pressed down, allowing the inner connecting rod 32 to be removed from the outer connecting rod 31.

[0028] Alternatively, several positioning holes can be correspondingly opened at intervals along the length of the outer and inner connecting rods. The inner connecting rod passes through the outer connecting rod, the positioning holes are aligned, and then the inner and outer connecting rods are connected and fixed by inserting pins into the positioning holes in the inner and outer connecting rods. To adjust the length of the connecting device, the inner connecting rod is inserted into the outer connecting rod to a certain depth, the positioning holes are aligned, and then the length is adjusted by fixing it with pins.

[0029] The length adjustment device of the connecting device is formed by the combination of the positioning hole of the outer rod and the elastic protrusion of the inner rod, or by the combination of the positioning holes on the outer rod and the inner rod with the pin.

[0030] Guardrails can be modularized and reassembled according to different length requirements; see [link / reference]. Figure 7 It has excellent applicability and convenience.

[0031] A prefabricated guardrail, the workflow is as follows: The standardized guardrail post assembly 2 and connecting device 3 are pre-arranged according to the site dimensions and modular design. After positioning and marking, the foundation assembly 1 is fixed to the foundation. First, the post assembly 2 is aligned and lowered according to the positioning mark 12. Then, the limit switch 22 rotates 90° clockwise to control the transmission rod 23, driving the rotating component 242 to rotate. The arc-shaped surface structure of the rotating component 242 drives the limit rod 243 to shift, pressing the spring plate 14 and extending into the limit hole 13 to achieve a tight connection and positioning installation between the post assembly 2 and the foundation assembly 1. The limit switch is then positioned on the end face of the guardrail post using a pin. Finally, the connecting device 3, with its adjusted length, is installed. Disassembly is performed by reversing the operation.
