A water pipe is provided under the guardrail, and the two end heads of the water pipe are plugged into the open groove at one end of the support. A threaded sleeve is provided on the outside of one end of the plug, and a strip groove is provided above the open groove. A locking mechanism is provided in the strip groove, and a plug is provided at one end of the support, which is threadedly connected to the threaded sleeve.

[0004] The above temporary metal guardrail is provided with open grooves at both ends of the support. The open groove at one end of the support is connected to a water pipe, and a plug is connected to the open groove at the other end of the support. The two supports are connected by plugging the plug. By making the support hollow, when the guardrail is needed, the water source is connected to the end of the water pipe and water is injected into the support. This design improves its stability by injecting water. After the water is released, the support and the guardrail can be easily dismantled and moved, reducing the labor of the workers. However, in the actual use of the guardrail, it is necessary to find a water source at the construction site, and the water injection process is slow, time-consuming and labor-intensive, and there is a waste of water resources. In view of this, the present application proposes a temporary metal guardrail. Utility Model Content

The setting of the moving wheels 8 can facilitate the transportation and relocation of the temporary metal guardrail.

[0025] As a preferred implementation of this embodiment, a fixed support member 10 is also provided at the bottom of the installation base plate 3, and a positioning mechanism 11 is provided on the vertical arm 2, and the positioning mechanism 11 can position the fixed support member 10 at a position close to the installation base plate 3 and at a position lower than the moving wheel 8. Specifically, the fixed support member 10 includes a bottom support plate 12 horizontally arranged at the bottom of the installation base plate 3, and support columns 13 are vertically fixed at both ends of the bottom of the bottom support plate 12. When the fixed support member 10 is positioned at a position lower than the moving wheel 8, the support column 13 abuts against the ground, and the temporary metal guardrail support can be positioned to facilitate the enclosure of the construction site.

[0026] In this embodiment, the positioning mechanism 11 includes a push rod 14 vertically penetrated in the vertical arm 2, the bottom end of the push rod 14 passes through the bottom wall of the vertical arm 2 and the mounting base plate 3 and is fixedly connected to the bottom support plate 12, a baffle 15 is fixed to the top of the push rod 14, a spring 17 is sleeved on the push rod 14 located between the baffle 15 and the bottom wall inside the vertical arm 2, a push handle 16 is horizontally fixed on the side wall of the baffle 15, and an adjusting groove 18 and a limiting groove 19 are vertically opened on the adjacent two side walls of the vertical arm 2 respectively, the push handle 16 passes through the adjusting groove 18 horizontally, the limiting groove 19 is aligned with and connected to the bottom end of the adjusting groove 18, and the top of the limiting groove 19 is lower than the top of the adjusting groove 18. Through this structural mode, the push handle 16 is pushed into the adjustment groove 18, and the baffle 15 is pushed under the elastic force of the spring 17 to drive the bottom support plate 12 to move upward. The support column 13 will be close to the installation base plate 3 and located above the moving wheel 8. At this time, the moving wheel 8 can be used to facilitate the movement and transportation of the temporary metal guardrail. By pushing the push handle 16 downward and lifting the guardrail body 1 at the same time, the push handle 16 slides to the bottom end of the adjustment groove 18, and then the push handle 16 is horizontally pushed into the limit groove 19. The push handle 16 is inserted into the limit groove 19 under the elastic force of the spring 17. At this time, the bottom support plate 12 and the support column 13 are positioned below the moving wheel 8, and the support column 13 is in contact with the ground and can be used for fixed support of the temporary metal guardrail.

[0027] As a preferred implementation of this embodiment, the guardrail body 1 includes two horizontally arranged horizontal arms 4 and a plurality of columns 5 vertically fixed between the two horizontal arms 4. The top and bottom ends of the side walls of the vertical arms 2 are provided with connecting ear plates 9, which are bolted to the horizontal arms 4 to facilitate the assembly of the temporary metal guardrail. A plug-in hole 20 is provided at the top of one of the vertical arms 2, and a connecting top plate 21 is horizontally fixed to the top of the other vertical arm 2. A plug-in column 22 capable of being inserted into the plug-in hole 20 is vertically fixed to the lower surface of the connecting top plate 21 away from one end of the vertical arm 2. Through the plug-in cooperation between the plug-in column 22 and the plug-in hole 20, multiple temporary metal guardrails can be connected in sequence. A support rod 6 is vertically fixed to the horizontal arm 4 located at the top of the vertical arm 2, and a warning sign 7 is installed at the top of the support rod 6. During the process of the temporary metal guardrail enclosing the construction site, the warning sign 7 can serve as a warning.

[0028] When in use, by plugging and matching the plug-in columns 22 at the top of the two vertical arms 2 with the plug-in holes 20, multiple temporary metal guardrails can be connected in sequence for the enclosure of the construction site. Secondly, when the push handle 16 is pushed into the adjustment slot 18, the baffle plate 15 is pushed under the elastic force of the spring 17 to drive the bottom support plate 12 to move up, and the support column 13 will be close to the installation base plate 3 and located above the moving wheel 8. At this time, the moving wheel 8 can be used to facilitate the movement and transportation of the temporary metal guardrail. When the push handle 16 is pushed down, the push rod 14 is used to push the support column 13 at the bottom end of the bottom support plate 12 In contact with the ground, lift the guardrail body 1 at the same time, make the push handle 16 slide to the bottom of the adjustment slot 18, and then horizontally move the push handle 16 into the limit slot 19. After loosening the guardrail body 1 and the push handle 16, the elastic force of the spring 17 pushes the baffle 15 to move up, and the push handle 16 retreats and is stuck in the limit slot 19. At this time, the bottom support plate 12 and the support column 13 are positioned below the moving wheel 8. The support column 13 is in contact with the ground and can be used for fixed support of the temporary metal guardrail. The overall structure is simple and reasonable, easy to splice, convenient to carry and move, and convenient for support and fixation during construction site enclosure.
