Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, and in particular to a temporary, detachable construction guardrail for the renovation of old residential areas. Background Technology

[0002] During the renovation of old residential areas, the installation of safety barriers is crucial to ensuring the safety of construction workers and surrounding residents.

[0003] However, traditional guardrails often have many problems. For example, some guardrails use welded structures, which are complex to construct, and the materials are difficult to reuse. This not only results in high processing and manufacturing costs, but also makes them prone to safety accidents during on-site welding. Other guardrails are built using scaffolding, which is extremely disadvantageous when the construction space is small and temporary protection is needed. Some temporary guardrails are connected to steel pipes with fasteners, but the operation is cumbersome when connecting and dismantling them, and their application is relatively fixed, making it difficult to adapt to the complex and ever-changing environment in the renovation of old residential areas. At the same time, if welded or inconveniently dismantled guardrails are used on elevators in old residential areas, they cannot be opened and closed quickly and temporarily, which means that some large equipment / materials need to be completely dismantled when entering or leaving, increasing construction risks.

[0004] Therefore, it is necessary to provide a new type of temporary, detachable construction safety barrier for the renovation of old residential areas to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a temporary, detachable construction safety railing for the renovation of old residential areas.

[0006] The temporary detachable construction guardrail for the renovation of old residential areas provided by this utility model includes a base plate and a top plate. Multiple equidistant rotating connecting seats are fixedly installed on the base plate, and each rotating connecting seat is equipped with a rotating support column. Multiple equidistant rotating connecting frames are installed on the lower surface of the top plate, and the rotating connecting frames are rotatably connected to the column heads of the corresponding support columns through a rotating shaft.

[0007] The top plate and the outermost support column are equipped with a buckle assembly, which includes a fixing block and a mounting plate. The fixing block is fixedly installed on the outermost support column, and a horizontally set horizontal plate is fixedly installed on the fixing block. The horizontal plate has a through hole. The mounting plate is fixedly installed on the lower surface of the top plate, and two symmetrically distributed sliding rods are fixedly installed on the mounting plate. A sliding connecting plate is provided between the two sliding rods, and a vertically set locking rod is fixedly installed on the lower surface of the connecting plate. A spring is sleeved on each sliding rod.

[0008] Preferably, one end of the spring is fixedly connected to the inner top wall of the mounting plate, and the other end of the spring is fixedly connected to the upper surface of the connecting plate.

[0009] Preferably, the locking rod corresponds to the through hole.

[0010] Preferably, a horizontally positioned handle is fixedly installed on the connecting plate.

[0011] Preferably, a protective net is installed between adjacent support columns.

[0012] Preferably, each of the supporting columns has two vertically distributed side grooves on its opposite column surfaces, and a hook rod is fixedly installed in each of the side grooves. Each of the four corners of the protective net is fixedly installed with a buckle, and the buckle is hooked onto the hook rod.

[0013] Preferably, one side of the rotating connecting seat is provided with an opening for the support column to rotate toward the mounting base plate, and the openings of the rotating connecting seat are in the same direction, while the buckle assembly is in the opposite direction to the opening of the rotating connecting seat.

[0014] Compared with related technologies, the temporary detachable construction guardrail for the renovation of old residential areas provided by this utility model has the following beneficial effects:

[0015] 1. The pull handle of this utility model causes the central plate to slide up along the sliding rod and compress the spring. At this time, the locking rod moves away from the through hole. Then, the top plate drives each support column to rotate around the rotating connecting seat. Under the restriction of the rotating connecting seat, the support column can only rotate into a vertical structure, which drives the locking rod on the central plate to be inserted into the through hole, so that the support column cannot rotate in the direction of the opening of the rotating connecting seat, thus quickly completing the assembly of the guardrail.

[0016] 2. When the guardrail is not in use, pulling the handle causes the central plate to slide up along the sliding rod and compress the spring. At this time, the locking rod slides away from the through hole, and the support column is rotated in the direction of the opening of the rotating connecting seat. Thus, the support column rotates to a horizontal position and fits against the base plate. The top plate also fits against the upper surface of the support column. Therefore, the entire guardrail can quickly shrink in size, making it easy for workers to move and store. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 6 This utility model provides a temporary detachable construction guardrail for the renovation of old residential areas, which includes a base plate 1 and a top plate 3.

[0027] In the embodiments of this utility model, please refer to Figures 1 to 6 Multiple equidistant rotating connecting seats 11 are fixedly installed on the mounting base plate 1, and each rotating connecting seat 11 is equipped with a rotating connecting support column 2. Multiple equidistant rotating connecting frames 31 are installed on the lower surface of the top plate 3, and the rotating connecting frames 31 are rotatably connected to the column heads of the corresponding support columns 2 through rotating shafts.

[0028] A buckle assembly 4 is mounted on the top plate 3 and the outermost support column 2. The buckle assembly 4 includes a fixing block 41 and a mounting plate 43. The fixing block 41 is fixedly mounted on the outermost support column 2, and a horizontally set horizontal plate 42 is fixedly mounted on the fixing block 41. The horizontal plate 42 has a through hole 42a. The mounting plate 43 is fixedly mounted on the lower surface of the top plate 3, and two symmetrically distributed sliding rods 44 are fixedly mounted on the mounting plate 43. A sliding connecting plate 45 is provided between the two sliding rods 44, and a vertically set locking rod 47 is fixedly mounted on the lower surface of the connecting plate 45. The locking rod 47 corresponds to the through hole 42a. A horizontally set handle 48 is fixedly mounted on the connecting plate 45. A spring 46 is sleeved on each sliding rod 44. One end of the spring 46 is fixedly connected to the inner top wall of the mounting plate 43, and the other end of the spring 46 is fixedly connected to the upper surface of the connecting plate 45.

[0029] It should be noted that when using guardrails for protection, the mounting base plate 1 is fixed to the area to be protected using screws. Pulling up the handle 48 causes the central connecting plate 45 to slide up along the sliding rod 44 and compress the spring 46. At this time, the locking rod 47 moves away from the through hole 42a. Then, the top plate 3 drives each support column 2 to rotate around the rotating connecting seat 11 (turning the support column 2 from the side with the opening of the rotating connecting seat 11 to the direction where the rotating connecting seat 11 has no opening). Since the rotating connecting seat 11 only has an opening on one side, the support column 2 can only rotate into a vertical structure under the restriction of the rotating connecting seat 11. After completion, release the handle 48, and under the action of the spring 46, drive the locking rod 47 on the central connecting plate 45 to be inserted into the through hole 42a. Thus, the locking of the support column 2 and the top plate 3 is completed, so that the support column 2 cannot rotate towards the opening of the rotating connecting seat 11, and the assembly of the guardrail can be completed quickly.

[0030] When the guardrail is not in use, pulling up the handle 48 causes the central connecting plate 45 to slide up along the sliding rod 44 and compress the spring 46. At this time, the locking rod 47 slides away from the through hole 42a, and the support column 2 is rotated in the direction of the opening of the rotating connecting seat 11. Thus, the support column 2 is rotated to a horizontal position and fits against the base plate 1. The top plate 3 also fits against the upper surface of the support column 2, realizing single-person hand gesture folding. Therefore, the entire guardrail can quickly shrink in size, making it easy for staff to move and store.

[0031] In this embodiment: when a large structural component (a door frame installed beyond the guardrail area) needs to be lifted into the work area inside the guardrail by workers, the guardrail can be retracted to facilitate workers lifting the large component over the guardrail, thus eliminating the need to dismantle the guardrail.

[0032] At the same time, this application can also be installed on elevators built in old residential areas. Therefore, when some large equipment / materials are moved upstairs by elevator, the guardrail can be retracted so that the large equipment / materials can be moved onto the elevator.

[0033] Furthermore, one side of the rotating connecting seat 11 is provided with an opening for the support column 2 to rotate toward the mounting base plate 1, and the openings of the rotating connecting seat 11 are in the same direction, so that the support column 2 can only rotate through the rotating connecting seat 11 toward the direction of the opening of the rotating connecting seat 11. The latching assembly 4 is located in the opposite direction to the opening direction of the rotating connecting seat 11, so that after the latching assembly 4 locks the top plate 3 and the support column 2, the latching assembly 4 restricts the support column 2 from rotating toward the direction of the opening of the rotating connecting seat 11.

[0034] In the embodiments of this utility model, please refer to Figures 1 to 6 A protective net 5 is installed between adjacent support columns 2. Specifically, two vertically distributed side grooves 2a are opened on the opposite column surfaces of the support columns 2. A hook rod 21 is fixedly installed in each side groove 2a. Locks 51 are fixedly installed at the four corners of the protective net 5, and the locks 51 are hooked onto the hook rod 21.

[0035] It should be noted that after the guardrail is installed and erected, the locks 51 on the protective net 5 are hooked onto the hook rods 21 at the corresponding positions in sequence, thereby completing the sealing and protection of the cavity structure between adjacent support columns 2.

[0036] The working principle of the temporary, detachable construction safety railing for the renovation of old residential areas provided by this utility model is as follows:

[0037] When using the guardrail for protection, the mounting base plate 1 is fixed to the area to be protected using screws. Pulling up the handle 48 causes the connecting plate 45 to slide up along the sliding rod 44 and compress the spring 46. At this time, the locking rod 47 moves away from the through hole 42a. Then, the top plate 3 drives each support column 2 to rotate around the rotating connecting seat 11 (turning the support column 2 from the side with the opening of the rotating connecting seat 11 to the direction where the rotating connecting seat 11 has no opening). Since the rotating connecting seat 11 only has an opening on one side, the support column 2 can only rotate into a vertical structure under the restriction of the rotating connecting seat 11. After completion, release the handle 48, and under the action of the spring 46, the locking rod 47 on the connecting plate 45 is driven into the through hole 42a. Thus, the locking of the support column 2 and the top plate 3 is completed, so that the support column 2 cannot rotate towards the opening of the rotating connecting seat 11, and the assembly of the guardrail can be completed quickly.

[0038] When the guardrail is not in use, pulling up the handle 48 causes the central connecting plate 45 to slide up along the sliding rod 44 and compress the spring 46. At this time, the locking rod 47 slides away from the through hole 42a, and the support column 2 is rotated in the direction of the opening of the rotating connecting seat 11. Thus, the support column 2 is rotated to a horizontal position and fits against the base plate 1, while the top plate 3 also fits against the upper surface of the support column 2. Therefore, the entire guardrail can quickly shrink in size, making it easy for workers to move and store.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
