Description

Technical Field

[0001] This application relates to the field of guardrail technology, and more specifically, to guardrails for foundation pits in building construction. Background Technology

[0002] Construction sites involve the use of a large number of construction machines and equipment, making their safety requirements different from those of conventional sites. Therefore, a large number of foundation pit guardrails are needed at the boundaries of construction sites to distinguish between construction and non-construction areas, preventing vehicles and pedestrians from falling into the foundation pit and causing safety accidents.

[0003] The existing technology publication CN221799416U provides a foundation pit guardrail. By setting up a separation mechanism, after the guardrail and extension rod are damaged by external impact, the workers can rotate the guardrail and extension rod to unscrew them from the threaded grooves and welded nuts on the base plate. Then, the damaged guardrail and extension rod can be pulled out through the through hole and separated from the guardrail. The workers only need to reinstall the new guardrail and extension rod into the threaded groove, without replacing the entire guardrail, thus reducing the operating cost. By setting up a base frame, fixing pins, and limiting grooves, the workers can simultaneously rotate the extension rods on both sides, causing the extension rods to rotate along the welded nuts. During the rotation, the extension rods drive the fixing pins along the limiting grooves to insert into the soil through the through hole at the bottom of the guardrail and connect with the ground, thereby improving the impact resistance and safety of the guardrail.

[0004] Although the device has many beneficial effects, the following problems still exist: When workers install the guardrail, if the installation direction of the guardrail is incorrect, causing the warning words on the warning sign to face the construction site instead of the direction of pedestrians or oncoming vehicles, the workers need to disassemble and reassemble the guardrail as a whole, which can easily reduce the flexibility of the guardrail when it is used. In view of this, we propose the construction pit guardrail. Utility Model Content

[0005] This application provides a construction pit guardrail, which solves the technical problem in the prior art where, when workers install guardrails in the wrong direction, causing the warning lettering on the warning sign to face the construction site instead of the direction of pedestrians or oncoming vehicles, workers need to disassemble and reassemble the entire guardrail, thus reducing the flexibility of the guardrail during use. The new application enables workers to quickly adjust the warning sign when they find that the warning lettering on the warning sign is facing the construction site instead of the direction of pedestrians or oncoming vehicles after installation, without having to disassemble and reassemble the entire guardrail, thereby improving the flexibility of the guardrail during use.

[0006] This application provides a construction pit guardrail, including: a guardrail panel;

[0007] Both sides of the railing are fixedly connected to support frames, and both sides of the top of the support frames are through holes with ground nails installed in the holes. A warning sign is connected to the top of the railing through a positioning mechanism.

[0008] The positioning mechanism includes a connecting plate located at the top of the guardrail. The warning sign is fixedly connected to the bottom of the connecting plate. A slot is provided through the top of the front of the guardrail. An insert is fixedly connected to the top of the inner wall of the connecting plate. The insert is slidably connected to the slot.

[0009] By adopting the above technical solution and setting up a positioning mechanism, when workers find that the warning words on the warning sign are facing the construction site instead of the direction of pedestrians or oncoming vehicles after the installation of the guardrail, the workers can quickly adjust the warning sign without having to disassemble and reassemble the entire guardrail, thus improving the flexibility of the guardrail during use.

[0010] Optionally, both the insert and the slot have a convex cross-section.

[0011] By adopting the above technical solution, when the staff aligns the plug with the slot and slides it in, the convex cross-section design can ensure a stable connection between the plug and the slot, making it difficult for the plug to slip out of the slot. This enhances the stability of the connection between the connecting plate and the guardrail, and also keeps the warning sign stable, preventing it from falling or tilting, thereby improving the overall safety and reliability of the guardrail.

[0012] Optionally, a fixing plate is fixedly connected to both the front and back of the panel. A through hole is opened on one side of the fixing plate, and a sliding rod is slidably connected in the through hole. A stop block for blocking the slot and the plug is fixedly connected to one end of the sliding rod.

[0013] By adopting the above technical solution, and by setting a fixed plate, a sliding rod, and a stop block, when the worker inserts the plug into the slot, the worker can move the sliding rod to move the stop block, so that the stop block can be moved to a position that blocks the slot and the plug block is positioned between the two stops block, thereby effectively preventing the plug block from falling out of the slot and improving the stability of the connecting plate and the warning sign.

[0014] Optionally, a pull plate is fixedly connected to the other end of the slide rod, and the dimensions of both the pull plate and the stop block are larger than the dimensions of the inner side of the through hole.

[0015] By adopting the above technical solution, when the direction of the warning sign needs to be adjusted, the staff can easily pull the pull plate, which in turn moves the sliding rod and the stop. Since the size of the pull plate and the stop are both larger than the inner size of the through hole, they cannot enter the through hole, thus effectively preventing the sliding rod from falling out of the through hole.

[0016] Optionally, a spring is fixedly connected to the side of the stop block near the slide rod, and one end of the spring is fixedly connected to the fixing plate.

[0017] By adopting the above technical solution and setting a spring, when the worker pulls the pull plate to move the slide bar and the stop block, the stop block moving towards the fixed plate will compress the spring. Thus, when the worker releases the pull plate, the compressed spring rebounds and can drive the stop block to quickly return to its original position, making the operation simpler and thus improving the worker's work efficiency.

[0018] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0019] 1. By setting up a positioning mechanism, when workers find that the warning lettering on the warning sign is facing the construction site instead of the direction of pedestrians or oncoming vehicles after the guardrail installation is completed, the workers can quickly adjust the warning sign without having to disassemble and reassemble the entire guardrail, thus improving the flexibility of the guardrail during use.

[0020] 2. By setting up a fixed plate, sliding rod, and stop, when the worker inserts the plug into the slot, the worker can move the sliding rod to move the stop, so that the stop can be moved to a position that blocks the slot and the plug is positioned between the two stops, thereby effectively preventing the plug from falling out of the slot and improving the stability of the connecting plate and warning sign.

[0021] 3. By setting a spring, when the worker pulls the pull plate to move the slide bar and the stop block, the stop block moving towards the fixed plate will compress the spring. When the worker releases the pull plate, the compressed spring rebounds and can quickly reset the stop block, making the operation simpler and thus improving the worker's work efficiency.

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1 and Figure 2 This application discloses a construction pit guardrail. The construction pit guardrail includes: a parapet 1;

[0029] Both sides of the guardrail 1 are fixedly connected to support frames 2. Both sides of the top of the support frame 2 are through-holes with ground nails 4 inside the holes. The top of the guardrail 1 is connected to a warning sign 5 through a positioning mechanism 3.

[0030] The positioning mechanism 3 includes a connecting plate 31, which is located at the top of the guardrail 1. The warning sign 5 is fixedly connected to the bottom of the connecting plate 31. A slot is provided through the top of the front of the guardrail 1. An insert block 32 is fixedly connected to the top of the inner wall of the connecting plate 31. The insert block 32 is slidably connected in the slot. After the workers fix the guardrail with the ground nails 4, they can adjust the warning sign 5 to prevent the warning lettering on the surface of the warning sign 5 from facing the construction site instead of the pedestrian direction due to incorrect installation direction of the guardrail. This eliminates the need for workers to disassemble and adjust the guardrail as a whole, thus improving the flexibility of the guardrail during use.

[0031] Reference Figure 2 and Figure 3 Both the insert 32 and the slot have a convex cross-section, which helps to prevent the insert 32 from detaching from the slot at will.

[0032] Reference Figure 3 and Figure 4 The front and back of the guardrail 1 are fixedly connected to a fixing plate 33. A through hole is opened on one side of the fixing plate 33, and a sliding rod 34 is slidably connected in the through hole. A stop block 35 is fixedly connected to one end of the sliding rod 34 to block the slot and the plug 32, so as to prevent the plug 32 from falling out of the slot at will, and further ensure the stability of the connecting plate 31 and the warning sign 5.

[0033] Reference Figure 3 and Figure 4 The other end of the slide rod 34 is fixedly connected to a pull plate 36. The size of both the pull plate 36 and the stop block 35 is larger than the size of the inner side of the through hole, so as to prevent the slide rod 34 from falling out of the through hole.

[0034] Reference Figure 3 and Figure 4A spring 37 is fixedly connected to the side of the stop block 35 near the slide bar 34. One end of the spring 37 is fixedly connected to the fixed plate 33, which helps to prevent the stop block 35 from moving at will.

[0035] Reference Figure 1 and Figure 2 The connecting plate 31 has an L-shaped cross section, and the distance between the vertical section of the connecting plate 31 and the guardrail 1 is greater than the width of the stop 35, so that the stop 35 can move between the vertical section of the connecting plate 31 and the guardrail 1.

[0036] Reference Figure 2 and Figure 3 The width of the insert 32 is equal to the distance between the two stops 35 on one side, so that the two sides of the insert 32 can fit into the two stops 35 respectively.

[0037] The implementation principle of the foundation pit guardrail in this application embodiment is as follows: In order to ensure the safety of pedestrians and construction workers at the construction site, foundation pit guardrails need to be installed. First, the support frames 2 on both sides of the guardrail 1 are placed at the required installation position. Ground nails 4 are driven into the ground through the openings on both sides of the top of the support frame 2 to ensure that the guardrail is stable and does not shake.

[0038] If, after the workers have finished installing the guardrails, they find that the warning lettering on warning sign 5 is facing the construction site instead of the direction of pedestrians or oncoming vehicles, the workers can adjust warning sign 5.

[0039] First, the staff can pull the pull plate 36 to move the slide bar 34. The movement of the slide bar 34 can move the stop block 35 and squeeze the spring 37, thereby exposing the slot. Then, the staff can pull the connecting plate 31 to move the warning sign 5 and the insert block 32 until the insert block 32 moves out of the slot.

[0040] Then, the staff can turn the warning sign 5 so that the warning words on the warning sign 5 face the direction of pedestrians or oncoming vehicles, and then insert the plug 32 back into the slot.

[0041] Finally, the staff releases the pull plate 36, causing the compressed spring 37 to rebound and move the stop block 35 away from the fixed plate 33 until the stop block 35 moves to a position that blocks the slot and the insert 32, so that the insert 32 will not fall out of the slot. Thus, if the staff finds that the installation direction of the guardrail is incorrect, they can quickly and easily adjust the direction of the warning sign 5 without disassembling the guardrail as a whole.

[0042] This application provides a construction pit guardrail. By setting a positioning mechanism 3, when the workers find that the warning words on the warning sign 5 are facing the construction site instead of the direction of pedestrians or oncoming vehicles after the guardrail is installed, the workers can quickly adjust the warning sign 5 without having to disassemble and reassemble the entire guardrail, thus improving the flexibility of the guardrail during use.
