DETAILED DESCRIPTION

[0020] In order to better understand the purpose, structure and function of the utility model, a telescopic platform guardrail of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1~Figure 4 As shown, a telescopic platform guardrail includes a fixed platform guardrail structure 1 and a sliding platform guardrail structure 2. The fixed platform guardrail structure 1 is composed of a fixed platform 11 and a fixed guardrail 12, and the sliding platform guardrail structure 2 is composed of a sliding platform 21 and a sliding guardrail 22. The fixed platform guardrail structure 1 and the sliding platform guardrail structure 2 can be synchronously overlapped and telescoped to facilitate on-site turnover operations.

[0022] The fixed platform 11 and the sliding platform 21 are welded by steel plates, flange plates and rib plates, and the fixed guardrail 12 and the sliding guardrail 22 are welded by square tubes.

[0023] The fixed platform 11 includes a first square frame, which is surrounded by a first side panel 111 connected to the front, rear and left sides. The first square frame is covered with a first panel 112. A fixed guardrail 12 is arranged on the front side of the fixed platform 11. The fixed guardrail 12 includes an inverted U-shaped peripheral fully enclosed rod 122 covering the front end of the fixed platform 11. A plurality of vertical rods 121 are arranged on the lower side of the horizontal rod in the peripheral fully enclosed rod 122 and connected to the end side of the fixed platform 11. A first horizontal rod 123 connecting the vertical rods in the peripheral fully enclosed rod 122 and the vertical rod 121 is arranged horizontally behind the vertical rod 121 and the peripheral fully enclosed rod 122.

[0024] The sliding platform 21 includes a second square frame, which is surrounded by second side panels 211 connected end to end on all sides. The second square frame is covered with a second panel 212. Corresponding connecting holes 4 are evenly spaced on the first side panels 111 and the second side panels 211 on the front and rear sides. The connecting holes 4 are aligned and a plurality of high-strength bolts are inserted to connect the fixed platform 11 and the sliding platform 21, so that the structure is stable.

[0025] A sliding guardrail 22 is arranged at the front side of the sliding platform 21. The sliding guardrail 22 is staggered and telescopic above the fixed guardrail 12, and includes an L-shaped outer semi-enclosed rod 221 covering the front end of the sliding platform 21. The transverse rod of the outer semi-enclosed rod 221 is slidably connected above the transverse rod of the outer fully enclosed rod 122. A second transverse rod 222 is transversely arranged behind the vertical rod of the outer semi-enclosed rod 221, and the second transverse rod 222 is slidably connected above the first transverse rod 123. Spacing holes are vertically provided on the transverse rods of the outer fully enclosed rod 122 and the outer semi-enclosed rod 221, the first transverse rod 123, and the second transverse rod 222. After being extended and retracted into place, they are fixed with latches to ensure the safety of the workers during construction. The length direction of the fixed guardrail 12 and / or the sliding guardrail 22 is relatively extended to the outside, so that within the telescopic range of the sliding platform 21, the fixed guardrail 12 and the sliding guardrail 22 always partially overlap, ensuring that the sliding guardrail 22 slides and retracts on the fixed guardrail 12.

[0026] In this embodiment, the left and right parts of the first panel 112 are inclined downward toward both sides to ensure that the sliding platform 21 is laterally contracted in the first square frame at the bottom of the fixed platform 11. The bottom of the fixed guardrail 12 and the sliding guardrail 22 are welded with a skirting board 3 to effectively prevent falling objects.

[0027] The utility model provides a telescopic platform guardrail, which has a reasonable and reliable structural design, a high safety factor, is easy to install and transport, and can be widely used in the construction of various combined steel formwork platform guardrails.
