Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, and more specifically, to a construction guardrail for municipal engineering. Background Technology

[0002] Municipal engineering refers to urban infrastructure construction projects, encompassing the construction and maintenance of various public facilities and utilities in a city, including but not limited to urban roads, bridges, tunnels, water supply and drainage systems, sewage treatment facilities, gas supply systems, heating supply systems, public transportation facilities, environmental sanitation facilities, and urban lighting. It is a vital support for the normal operation and development of a city, playing a crucial role in improving the quality of life for urban residents and promoting urban economic development and social progress.

[0003] Construction safety barriers play a vital role in municipal engineering projects. First, they ensure construction safety and the safety of personnel by isolating the construction area from the outside world, preventing unauthorized personnel from entering the site and avoiding potential hazards such as falling objects or excavated pits. They also prevent construction workers from accidentally entering dangerous areas. Second, construction safety barriers help maintain order at the construction site, clearly defining the construction area and ensuring the orderly placement of construction equipment and materials, preventing the occupation of non-construction areas and guaranteeing the normal functioning of urban traffic and residents' lives. Furthermore, safety barriers serve a warning function, using their conspicuous colors and markings to alert pedestrians and vehicles to construction activities, allowing them to prepare to avoid or slow down, thus reducing the occurrence of traffic accidents.

[0004] In existing technologies, construction safety barriers typically consist of two posts and a horizontal bar or mesh panel connecting them. The posts provide positioning, while the horizontal bar or mesh panel acts as a barrier. However, the barrier formed by the horizontal bar or mesh panel has openings, primarily for visibility or ventilation. But in certain specific construction scenarios, such as bank vault renovation projects involving high security and confidentiality requirements, it's necessary to prevent outsiders from observing construction details; or the construction of R&D centers for high-tech companies, which may involve patented technologies, core processes, and other trade secrets, both requiring highly concealed operations. The aforementioned construction safety barriers lack a sealing function and cannot meet these concealed construction needs, thus greatly limiting their application. Utility Model Content

Detailed Implementation

[0027] The embodiments of this application will now be described in detail with reference to the accompanying drawings. Example

[0028] Please refer to Figures 1-7 This application provides a construction safety railing for municipal engineering, comprising: a railing body including a first post 2, a second post 3, and a crossbar 4. The first post 2 and the second post 3 are parallel and spaced apart. The crossbar 4 is disposed between the first post 2 and the second post 3 to connect them. Multiple crossbars 4 are provided and evenly spaced along the extension direction of the first post 2. A first mounting groove 1 is provided on the side of the first post 2 facing the second post 3. 2; a shielding structure, including a roller 11, a flexible shielding sheet 13, and a positioning strip 9, wherein the roller 11 is rotatably disposed in the first mounting groove 12 and is disposed along the extending direction of the first column 2, the flexible shielding sheet 13 is wound around the roller 11, and the positioning strip 9 is disposed at the winding end of the flexible shielding sheet 13 for driving the flexible shielding sheet 13 to unfold and cover the space between the first column 2 and the second column 3; and an adjustment structure 5 for adjusting the forward or reverse rotation of the roller 11.

[0029] The construction safety barrier of this application utilizes the rotation of roller 11 to control the state of the flexible shielding sheet 13. In use, when ventilation or dust removal is required, adjusting structure 5 causes roller 11 to rotate forward, allowing the flexible shielding sheet 13 to wrap around roller 11, ensuring the space between the first post 2 and the second post 3 is unobstructed and meeting ventilation and dust removal needs. In concealed construction sites, adjusting structure 5 causes roller 11 to rotate in the opposite direction, while simultaneously adjusting the position of positioning strip 9, causing the flexible shielding sheet 13 on roller 11 to unfold and cover the space between the first post 2 and the second post 3, thus achieving shielding of that space. Its advantage lies in cleverly solving the problem of existing construction safety barriers failing to meet the needs of concealed construction through simple roller 11 rotation adjustment. It can guarantee ventilation and other functions in ordinary scenarios while achieving effective shielding in specific concealed construction scenarios, greatly expanding the application range of construction safety barriers.

[0030] Optionally, the flexible shielding sheet 13 can be black cloth, and the bottom sides of the first post 2 and the second post 3 are provided with mounting plates. The two sides of the mounting plates extend to the front and rear sides of the guardrail, respectively, and are provided with grounding bolts.

[0031] In a preferred embodiment, the positioning strip 9 is a magnetic component, and the second column 3 is provided with a magnet 16 for adsorbing the positioning strip 9.

[0032] In the above embodiment, when the flexible shielding sheet 13 is unfolded and covers the space between the first post 2 and the second post 3, the magnetic positioning strip 9 and the magnet 16 on the second post 3 attract each other, which can firmly fix the winding end of the flexible shielding sheet 13, ensuring that the shielding structure remains stable during use and will not easily shake or shift due to external forces such as wind, thereby ensuring the shielding effect during concealed construction and improving the reliability and practicality of the guardrail in actual application.

[0033] In a preferred embodiment, the second column 3 is provided with a second mounting groove 15, the magnet 16 is disposed at the bottom of the second mounting groove 15, and the space of the second mounting groove 15 outside the magnet 16 is used for insertion and engagement with the positioning strip 9.

[0034] In the above embodiment, the second post 3 is provided with a second mounting groove 15, and the magnet 16 is placed at the bottom of the groove. Simultaneously, the groove space outside the magnet 16 is used for insertion and engagement with the positioning strip 9, bringing several advantages. On the one hand, the mounting groove protects the magnet 16, preventing damage during construction due to collisions, thus extending its service life. On the other hand, the positioning strip 9 can be precisely inserted into the space of the second mounting groove 15, tightly engaging with the magnet 16, further enhancing the stability of the connection between the positioning strip 9 and the second post 3. This ensures that the flexible shielding sheet 13 can stably cover the space between the two posts after unfolding, improving the performance of the guardrail in concealed construction scenarios.

[0035] In a preferred embodiment, the aforementioned adjustment structure 5 is a drive motor.

[0036] In the above embodiments, the use of a drive motor as the adjustment structure 5 enables precise, efficient and labor-saving control of the forward or reverse rotation of the roller 11, greatly improving the convenience and timeliness of the unfolding and retracting operation of the flexible shielding sheet 13.

[0037] In a preferred embodiment, any of the above-mentioned crossbars 4 is provided with a passage groove 8 at its center for passage of the positioning strip 9 and the flexible shielding piece 13.

[0038] In the above embodiments, when the flexible shielding plate 13 is unfolded or retracted, the positioning strip 9 and the flexible shielding plate 13 can pass smoothly through the passage groove 8 without being obstructed by the crossbar 4, ensuring the normal operation of the shielding structure and preventing damage to the flexible shielding plate 13 or displacement of the positioning strip 9 due to interference with the crossbar 4 during operation. This ensures the stability and reliability of the guardrail when switching between ventilation and concealment functions. Furthermore, when working in concealed spaces, the flexible shielding plate 13 is located within the passage groove 8, which improves its stability.

[0039] In a preferred embodiment, a connecting strip 6 is also included, one end of which is connected to the top of the first column 2 and the other end of which is connected to the top of the second column 3.

[0040] The positioning strip 9 is provided with a guide slider 10, and the connecting strip 6 is provided with a guide groove 7 adapted to the guide slider 10.

[0041] In the above embodiments, the connecting strip 6 enhances the connection stability at the top of the first post 2 and the second post 3, improving the overall structural strength of the guardrail. The guide slider 10 cooperates with the guide groove 7 to provide precise guidance for the positioning strip 9 during the unfolding or retraction of the flexible shielding sheet 13, ensuring that the positioning strip 9 moves smoothly and steadily, preventing it from shifting or getting stuck during movement, and ensuring that the flexible shielding sheet 13 can accurately and efficiently cover or retract, further optimizing the performance of the guardrail.

[0042] In a preferred embodiment, the opening of the first mounting groove 12 is provided with a third positioning groove for interlocking with the positioning strip 9.

[0043] In the above embodiment, the first mounting groove 12 is provided with a third positioning groove that is inserted and engaged with the positioning strip 9. This allows the positioning strip 9 to be accurately positioned when the flexible shielding sheet 13 is retracted and wrapped around the roller 11, preventing it from shaking randomly, ensuring that the guardrail is neat and orderly, and providing a convenient starting position for the next unfolding of the flexible shielding sheet 13.

[0044] In a preferred embodiment, the first mounting groove 12 is provided with two guide wheels 14 for clamping the flexible shielding sheet 13.

[0045] In the above embodiments, when the roller 11 rotates and drives the flexible shielding sheet 13 to move, the guide wheel 14 can play a good guiding and supporting role, ensuring that the flexible shielding sheet 13 runs smoothly, avoiding twisting, wrinkling and other conditions, extending its service life, and at the same time making the operation process smoother, improving the convenience and reliability of the guardrail.
