Description

Technical Field

[0001] This utility model relates to the field of construction guardrail technology, specifically to a construction safety guardrail. Background Technology

[0002] Construction guardrails are a common protective tool used in construction sites to ensure the safe and smooth progress of construction. Because construction sites contain many dangerous items such as building materials, machinery and equipment, and engineering vehicles, as well as dangerous construction scenarios such as working at heights and deep foundation pits, safety guardrails need to be set up during construction to protect the safety of workers and pedestrians, to distinguish between construction areas and non-construction areas, and to remind pedestrians and vehicles to pay attention to safety.

[0003] Currently, construction guardrails are mostly one-piece structures, which are inconvenient to disassemble during transportation and assembly, requiring multiple people to work together. They also occupy a lot of space and are heavy, making transportation inconvenient and increasing labor intensity. Utility Model Content

[0004] To address the problem that existing construction guardrails are inconvenient to transport and assemble, this utility model provides a construction safety guardrail.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A construction safety railing, comprising:

[0007] The outer frame includes two sets of parallel horizontal frames and two sets of vertical folding frames. The two sets of horizontal frames and the two sets of vertical folding frames form a rectangular frame. The horizontal frames and the vertical folding frames are rotatably installed. Each set of vertical folding frames includes two vertical frames. The two vertical frames are hinged by a first hinge, and the first hinge is close to the outside of the vertical frame, so that the vertical folding frame can only be folded inward.

[0008] A side panel is installed on the inside of the outer frame when the outer frame is unfolded, and the side panel is used to restrict the vertical folding frame of the outer frame from folding inward.

[0009] Support feet, which are fixedly installed at the bottom of the outer frame.

[0010] As a further description of the above technical solution:

[0011] A limiting component is fixedly installed on the panel, and the limiting component includes:

[0012] The outer shell is fixedly connected to the guard plate. A guide hole is provided inside the outer shell, and a retractable part is provided near the operating end of the outer shell.

[0013] The insertion rod is slidably disposed in the guide hole, and one end of the insertion rod extends out from the inner hole of the contraction part and is fixedly provided with an operating section;

[0014] A fixing ring is fixedly connected to the side of the insertion rod, and a return spring is sleeved on the insertion rod between the fixing ring and the retractable part;

[0015] The inner side of the outer frame is provided with insertion holes corresponding to the insertion rods.

[0016] As a further description of the above technical solution:

[0017] The vertical frame has insertion holes on its side.

[0018] As a further description of the above technical solution:

[0019] The panel components include:

[0020] The first railing and the second railing are hinged together by a second hinge member.

[0021] Both the first and second railings are fixedly equipped with limiting components.

[0022] As a further description of the above technical solution:

[0023] Both the first and second railings are perforated panels.

[0035] Please refer to the attached document. Figures 1-3 This illustration shows a construction safety railing provided in an embodiment of the present application, comprising: an outer frame 1, railing panels 3, and support legs 2.

[0036] The outer frame 1 includes two sets of parallel horizontal frames 101 and two sets of vertical folding frames. The two sets of horizontal frames 101 and the two sets of vertical folding frames form a rectangular frame, and the horizontal frames 101 and the vertical folding frames are rotatably mounted. Specifically, the two ends of the two sets of horizontal frames 101 and the two ends of the two sets of vertical folding frames form four connection positions, all of which are rotatably mounted. Each set of vertical folding frames includes two vertical frames 103, which are hinged by a first hinge 104. The first hinge 104 is close to the outer side of the vertical frame 103, so that the vertical folding frame can only be folded inward. The two sets of vertical folding frames... The frames are symmetrically distributed. When folded, both sets of vertical folding frames fold inwards simultaneously, reducing the distance between the two sets of horizontal frames 101, thus enabling the outer frame 1 to fold. The guardrail panel 3 is installed inside the outer frame 1 when it is unfolded, and it restricts the vertical folding frames of the outer frame 1 from folding inwards. That is, after the guardrail panel 3 is installed inside the outer frame 1, the outer frame 1 can no longer be folded, forming a panel-like guardrail surface. The support legs 2 are fixedly installed at the bottom of the outer frame 1, supporting it and allowing it to stand upright. Figure 1 As shown, the guardrail panel 3 is installed inside the outer frame 1, forming a panel-like guardrail surface, and is stably supported by the support legs 2, thus constituting a construction safety guardrail.

[0037] In this embodiment, the guardrail panel 3 is an independent structure that can be detached and placed separately. The outer frame 1 is foldable and occupies less space, making it easy to disassemble and place the outer frame 1 and guardrail panel 3 of the construction safety guardrail separately for easy transportation. The structure of the outer frame 1 is specifically designed. After the guardrail panel 3 is installed inside the outer frame 1 in the unfolded state, the guardrail panel 3 restricts the folding deformation of the outer frame 1, thereby ensuring the stability of the construction safety guardrail structure. This assembly process is relatively simple and can be quickly assembled and used in specific application locations.

[0038] In one embodiment, in order to facilitate the installation of the guardrail 3 inside the outer frame 1, a limiting member 4 is fixedly installed on the guardrail 3. The limiting member 4 includes: a housing 401, a plug rod 402, a fixing ring 403, and a return spring 404.

[0039] The outer casing 401 is fixedly connected to the panel 3. A guide hole is provided inside the outer casing 401. A retractable section is provided near the operating end 401a of the outer casing 401. The insertion rod 402 is slidably disposed within the guide hole, with one end of the insertion rod 402 extending from the inner hole of the retractable section and fixedly provided with an operating section 405. The other end of the insertion rod 402 also extends from the other end of the guide hole. A fixing ring 403 is fixedly connected to the side of the insertion rod 402. A return spring 404 is sleeved on the insertion rod 402, located between the fixing ring 403 and the retractable section. Under the action of the return spring 404, the fixing ring 403 is elastically pushed, causing the insertion rod 402 to move closer to the left end of the outer casing 401 (e.g., ...). Figure 3 As shown in the diagram, at this time, the operating section 405 is pressed against the operating end 401a of the outer casing 401. The inner side of the outer frame 1 is provided with a socket 103b corresponding to the insertion rod 402. When in use, the user manipulates the operating section 405 to move the insertion rod 402 to the right. The insertion rod 402 drives the fixing ring 403 to move. The outer casing 401 is in a fixed state. The contraction part of the guide hole on the outer casing 401 restricts the right end of the reset spring 404. The fixing ring 403 moves to the right to squeeze the reset spring 404. After the insertion rod 402 is aligned with the socket 103b, the left end automatically pops out under the action of the reset spring 404, and the insertion rod 402 is inserted into the socket 103b.

[0040] Specifically, the outer frame 1 is kept in the unfolded state, the side panel 3 is placed inside the outer frame 1, and then the side panel 3 is connected to the outer frame 1 with the limiting member 4.

[0041] In one embodiment, the vertical frame 103 has an insertion hole 103b on its side. At this time, the insertion rod 402 of the limiting member 4 is also designed to be horizontal. The limiting member 4 is connected to the vertical frame 103. This method is more stable than choosing to open the insertion hole 103b on the horizontal frame 101 and design the insertion rod 402 of the limiting member 4 to be vertical (the insertion hole 103b on the side of the vertical frame 103 makes the vertical frame 103 and the guardrail member 3 tightly connected, and the horizontal frame 101 itself is more stable).

[0042] In one embodiment, the guardrail member 3 includes: a first guardrail 301, a second guardrail 302, and a second hinge member 303.

[0043] The first guardrail 301 and the second guardrail 302 are hinged together by the second hinge 303. This design allows the guardrail 3 to be folded, making it easier to transport.

[0044] Both the first railing 301 and the second railing 302 are fixedly equipped with limiting components 4 to ensure that both the first railing 301 and the second railing 302 can be stably connected to the outer frame 1.

[0045] In order to reduce the weight and cost of the railing component 3, both the first railing 301 and the second railing 302 are designed to be hollowed-out components.

[0046] In one embodiment, a connecting seat 101a is fixedly provided on the inner side of the horizontal frame 101, and a connecting ear 103a is fixedly connected to the end of the vertical frame 103. The connecting ear 103a and the connecting seat 101a are rotatably installed by a pin.

[0047] In one embodiment, a reflective strip 102 is fixedly provided on the side of the transverse frame 101. The reflective strip 102 can be set at any position on the surface of the construction safety guardrail. However, since the transverse frame 101 does not fold in this solution, the reflective strip 102 is not easily damaged during transportation. Therefore, the reflective strip 102 is designed on the side of the transverse frame 101.

This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art not disclosed herein.
