Description

Technical Field

[0001] This utility model relates to the field of scaffolding, specifically a scaffolding with guardrails. Background Technology

[0002] Construction scaffolding is a temporary structural system that provides workers with operating platforms, transportation channels, and temporary support during the construction process. It is usually constructed from materials such as steel pipes, fasteners, scaffold boards, and safety nets. Its core function is to ensure the safety of construction workers and improve work efficiency.

[0003] The existing portal scaffolding technology is widely used in small and medium-sized projects due to its standardization and ease of operation. It is especially suitable for projects with high requirements for construction period and civilized construction. It adopts a modular design, and components such as the portal frame and crossbars are quickly connected by pin holes or bolts.

[0004] Regarding the aforementioned technologies, existing portal scaffolding has limited protective capabilities for construction workers due to its relatively simple structure. Workers are prone to falling from the scaffolding during construction due to instability, causing construction accidents. In summary, existing scaffolding technologies do not provide sufficient protection for construction workers. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a scaffold with guardrails to solve the technical problem that the existing scaffolds do not provide sufficient protection for construction workers.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a scaffold with guardrails, comprising a frame, the frame having a rectangular structure, and each of the four corners being connected to a column along the height direction, the column being fixedly connected to a guide groove along its own length direction, and also comprising a guardrail, the guardrail being arranged along the length direction of the frame and being able to slide within the guide groove along the height direction of the scaffold, and a positioning structure for limiting the sliding of the guardrail being provided between the guardrail and the column.

[0007] By adopting the above technical solution, a guardrail structure is set along the length of the scaffold. The guide groove welded on the column guides the movement of the guardrail structure, allowing the guardrail structure to be adjusted to a suitable height of the scaffold according to the needs of use, which facilitates the construction work of workers. When workers move to another layer of the scaffold, the guardrail structure can also slide to a suitable height to protect the workers, reducing unnecessary guardrail structures and effectively reducing the self-weight of the scaffold.

[0008] The present invention is further configured such that a sliding frame is fixedly connected to the edge of the guardrail, and the sliding frame can slide under the guidance of the guide groove.

[0009] Preferably, the sliding frame allows the guardrail to slide stably within the guide groove.

[0010] The present invention is further configured such that, inside the top of the sliding frame, telescopic strips are slidably connected to both ends along their own length direction, and each end of the telescopic strips that is far apart from each other is fixedly connected to a post, and the guardrail is provided with insertion holes for the posts to be inserted at intervals along the height direction.

[0011] Preferably, the height of the guardrail can be limited by inserting the post at the end of the telescopic bar into the corresponding hole, thereby achieving height positioning of the guardrail.

[0012] The present invention is further configured such that a handle is fixedly connected to one end of each telescopic bar that is close to the other.

[0013] Preferably, the handle facilitates worker control of the sliding of the telescopic bar.

[0014] The present invention is further provided that a compression spring in a compressed state is provided between the handles.

[0015] Preferably, the compression spring allows the telescopic bar to automatically return to its original position.

[0016] The present invention is further configured such that the stroke of the handle sliding towards each other is greater than the length of the insertion post.

[0017] Preferably, the insertion post can be easily pulled out of the insertion hole.

[0018] The present invention is further configured such that the four corners of the frame are all connected to the columns by bolts, and the guide groove is provided with a clearance opening at the bolt connection hole.

[0019] Preferably, the frame and the post can be quickly connected without affecting the normal sliding of the guardrail.

[0020] In summary, the present invention has the following main advantages:

[0021] This utility model features a guardrail structure installed along the length of the scaffolding. Guide grooves welded to the columns guide the movement of the guardrail structure, allowing it to be adjusted to a suitable height according to the needs of the scaffolding. This facilitates construction work for workers. Furthermore, when workers move to another level of the scaffolding, the guardrail structure can slide to a suitable height to protect them, reducing unnecessary guardrail structures and effectively lowering the weight of the scaffolding.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] First embodiment:

[0034] A type of scaffolding with guardrails, please refer to Figure 1-7 The scaffolding includes a frame 1. Specifically, the frame 1 has a support plate structure for workers to step on. The frame 1 is rectangular, and each of the four corners is connected to a column 2 along the height direction. The scaffolding has a support structure at the bottom of the lowest column 2. The support structure can be a support column or casters. Specifically, in this embodiment, the support structure is a support column. The column 2 is fixedly connected to a guide groove 3 along its own length direction. The scaffolding also includes a guardrail 4. The guardrail 4 is set along the length direction of the frame 1 and can slide in the guide groove 3 along the height direction of the scaffolding. A positioning structure is set between the guardrail 4 and the column 2 to limit the sliding of the guardrail 4.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 1-4The edge of the guardrail 4 is fixedly connected to a sliding frame 5. The sliding frame 5 can slide under the guidance of the guide groove 3, and the sliding frame 5 allows the guardrail 4 to slide stably in the guide groove 3.

[0036] Furthermore, the top of the sliding frame 5 is connected to telescopic strips 6 at both ends along its length. The ends of the telescopic strips 6 that are far apart from each other are fixedly connected to insert posts 9. The guardrail 4 is provided with insertion holes 301 at intervals along the height direction for inserting the insert posts 9. After the insert posts 9 at the ends of the telescopic strips 6 are inserted into the corresponding insertion holes 301, the height of the guardrail 4 can be limited, thereby achieving height positioning of the guardrail 4.

[0037] Second embodiment:

[0038] A type of scaffolding with guardrails, please refer to Figure 1-7 Based on the first embodiment, the difference from the first embodiment is that each end of the telescopic bar 6 that is close to each other is fixedly connected to a handle 7. The handle 7 makes it easy for the worker to control the sliding of the telescopic bar 6. Each handle 7 has a downward protrusion at the bottom of the end that is close to each other, so that the worker can hold the two handles 7 at the same time and bring them close to each other.

[0039] Furthermore, a compression spring 8 is provided between the handles 7, which can automatically reset the telescopic bar 6. The sliding stroke of the handles 7 is greater than the length of the plug 9, so that the plug 9 can be smoothly pulled out of the socket 301.

[0040] Specifically, when adjusting the position of the guardrail 4 across different levels of the scaffolding, the worker first stands on the lower level, holds the handle 7, and raises the sliding frame 5 as high as possible. Then, the worker releases the handle 7 and positions the sliding frame 5 to a higher position on the lower level. The worker then climbs up the ladder to the next higher level, squats down on one knee, holds the handle 7 at the higher position on the lower level, releases the sliding frame 5 from its position, and pulls it to the next higher level. This allows for easy adjustment of the guardrail 4's position. The reverse is also true.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 5-7 The four corners of the frame 1 are all connected to the columns 2 by bolts. The guide groove 3 is provided with a clearance opening 302 at the bolt connection hole, which can realize the quick connection between the frame 1 and the columns 2 without affecting the normal sliding of the guardrail 4.

[0042] In practical operation, after standing on the scaffold, the worker holds the two handles 7 at the top of the sliding frame 5 and moves them in opposite directions to compress the spring 8, causing the insert 9 to be pulled out from the insertion hole 301. This allows the position of the guardrail 4 to be adjusted along the height direction, moving the guardrail 4 to a position that does not affect operation, while still providing protection. When changing different floor heights on the scaffold, the sliding frame 5 can also be slid and adjusted to different floors in the same way, effectively reducing the weight of the scaffold and avoiding the need to install too many protective structures on the scaffold.

[0043] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
