[0002] During construction, it is necessary to install construction guardrails around the construction area to warn unauthorized personnel that entry is prohibited. However, existing construction guardrails have at least the following drawbacks: they are composed of guardrail panels and support posts, and to facilitate disassembly, the panels and posts are connected by hinges. In severe windy weather, the wind can easily cause the hinges to bend, resulting in the guardrail, which was originally straight, becoming bent and thus failing to function as a barrier.

[0003] The utility model disclosed in CN220353573U relates to a reinforcement device for construction guardrails, including a folding plate installed on an external device. The folding plate is equipped with a fixing mechanism and a reinforcement mechanism. The fixing mechanism includes a fixing rod, a support plate, a connecting plate, a transverse rod, a threaded section, a limiting sleeve, and a nut. The fixing rod is installed on the folding plate, and the two ends of the support plate are respectively connected to the fixing rod and the folding plate. The connecting plate is installed between the fixing rod and the folding plate. The transverse rod between the two connecting plates can effectively prevent the connecting plate from moving laterally, thereby enhancing the stability of use. Furthermore, the connection between the nut and the threaded section allows for easy disassembly and installation, improving the convenience of use.

[0004] The device disclosed in the above-mentioned utility model relies on a large number of components (such as fixing rods, connecting plates, horizontal rods, inner sleeves, etc.) when in use, which increases the complexity of assembly, makes installation time longer, and affects construction efficiency.

Several locking pipes are vertically distributed on both main poles, with the locking pipes on the same main pole facing the same direction. Two limiting rods are elastically connected to each locking pipe, and the two limiting rods are arranged opposite each other. Extension shafts are installed at both ends of the crossbars, and a first boss is slidably connected to the extension shaft, with a second boss installed at its top. When the crossbars are connected to the main poles, the two limiting rods contact the end of the second boss closest to the first boss.

[0007] Preferably, each of the two bases is provided with two reinforcing plates, the two reinforcing plates on the same base are arranged opposite each other, and the two ends of the reinforcing plates are respectively welded to the base and the connecting pipe.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A construction guardrail reinforcement device for construction buildings includes two bases 1, two main poles 2, and several crossbars 3. Each base 1 is welded with a connecting pipe 4, and the main poles 2 are inserted into the connecting pipes 4. Several locking pipes 5 are vertically distributed on each of the two main poles 2. The locking pipes 5 on the same main pole 2 are installed in the same direction. Two limiting rods 9 are elastically connected to each locking pipe 5. The two limiting rods 9 are arranged opposite to each other. Extension shafts 6 are installed at both ends of the crossbars 3. A first boss 7 is slidably connected to the extension shaft 6, and a second boss 8 is installed at its top. When the crossbars 3 are connected to the main poles 2, the two limiting rods 9 contact the end of the second boss 8 that is close to the first boss 7.

[0022] When using this device, first insert the two main rods 2 into the corresponding connecting pipes 4. Then, adjust the distance between the two bases 1 so that the adjusted distance matches the length of the crossbar 3. Then, insert the two ends of several crossbars 3 into the locking pipes 5. Then, control the bases 1 to move closer to each other, so that the main rods 2 drive the locking pipes 5 installed on them to move synchronously towards the crossbar 3. During the movement, the second protrusion 8 contacts the two limiting rods 9 and pushes the two limiting rods 9 to their outer periphery under the action of thrust. When the second protrusion 8 has completely moved to the other side of the limiting rod 9, the limiting rod 9 resets under the action of elasticity, restricting the second protrusion 8 to that position, thus completing the connection between the crossbar 3 and the main rod 2. When it is necessary to remove the crossbar 3 from the main rod 2, simply control the main rod 2 to move closer to the crossbar 3 again, so that the first protrusion 7 moves to the outside of the limiting rod 9. Then, control the main rod 2 to move quickly away from the crossbar 3, so that the limiting rod 9 moves to the outside of the first protrusion 7 and the second protrusion 8 to complete the removal work.

[0023] Specifically, in this embodiment, two reinforcing plates 10 are provided on each of the two bases 1. The two reinforcing plates 10 on the same base 1 are arranged opposite to each other. The two ends of the reinforcing plates 10 are respectively welded to the base 1 and the connecting pipe 4. Thus, the connection stability between the base 1 and the connecting pipe 4 is improved by setting the reinforcing plates 10, thereby improving the supporting force of the connecting pipe 4.

[0024] Specifically, in this embodiment, a rotating groove 13 is provided at the top of the connecting pipe 4, and two first sector blocks 11 are arranged opposite each other on the rotating groove 13. Two second sector blocks 12 are arranged on the lower circumference of the main rod 2, so that after the main rod 2 is inserted into the connecting pipe 4, the first sector blocks 11 and the second sector blocks 12 can be made to coincide by rotation, thereby improving the connection stability between the main rod 2 and the connecting pipe 4.

[0025] Specifically, in this embodiment, a cover plate 16 is slidably connected to the lower part of the main rod 2. The cover plate 16 is sleeved on the main rod 2, and its size is adapted to the rotating groove 13. When the main rod 2 is inserted into the connecting pipe 4, the rotating groove 13 can be covered by moving the cover plate 16, thereby preventing external debris from entering the rotating groove 13 and affecting the subsequent disassembly work.

[0026] Specifically, in this embodiment, the locking tube 5 is hollow, and the diameter of its hollow area is larger than the diameter of the first protrusion 7 and the second protrusion 8, so that the first protrusion 7 and the second protrusion 8 can move normally on the locking tube 5 through the hollow area, thereby achieving the installation and disassembly of the main rod 2 and the crossbar 3 by controlling the position between the first protrusion 7, the second protrusion 8 and the limiting rod 9.

[0027] Specifically, in this embodiment, two movable holes 14 are provided on the locking tube 5. The two movable holes 14 are arranged opposite to each other and are adapted to the limiting rod 9. By providing the movable holes 14, the limiting rod 9 can move on the locking tube 5, so that when the first boss 7 and the second boss 8 come into contact with the limiting rod 9, they can push the limiting rod 9 to move normally.

[0028] Specifically, in this embodiment, two limiting rods 9 on the same locking tube 5 are fitted with inclined blocks 15 at their close ends, so that when the limiting rod 9 is close to the first protrusion 7 and the second protrusion 8, the first protrusion 7 and the second protrusion 8 can push the limiting rod 9 to move through the inclined blocks 15, thereby achieving the purpose of pushing the limiting rod 9 to move.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
