This invention relates to the field of fencing technology, specifically disclosing a collision-resistant and buffer-type safety fence, comprising: a fixed pile mechanism, which includes a square hole, a circular hole, a hemispherical groove, a hollow cylindrical tube, and a fixed pile body. Two hollow cylindrical tubes are respectively located on the left and right sides of the top of the fixed pile body. A square hole communicating with the inner cavity of each hollow cylindrical tube is opened in the center of its front side. Circular holes penetrating vertically are opened on both the left and right sides of the bottom of the fixed pile body. Two hemispherical grooves are equidistantly spaced along the circumference at the top of the inner cavity of the fixed pile body. This device is not only easy to install and disassemble, and has excellent buffering performance, but also possesses good environmental adaptability, economy, and reusability. It fundamentally solves the problems of irreversible deformation, difficult maintenance, and inconvenient assembly and disassembly of traditional rigid guardrails, providing an efficient, flexible, and reliable solution for construction safety protection.

This invention relates to the field of concrete construction technology and discloses a formwork support device for concrete pouring construction. It includes two mutually rotatably connected support rods and corner pieces rotatably installed at the ends of the support rods. Both ends of the two support rods are telescopically adjustable. The corner pieces have two rotatably adjustable corner plates that abut against the two sides of the corner of the formwork. A stepped surface is formed on the outer wall of the corner plate, and a support plate abuts between the two opposite stepped surfaces of adjacent corner pieces, with the support plate in close contact with the formwork. This invention can flexibly adapt to various angles of window corners, including acute, right, and obtuse angles. Simultaneously, by utilizing diagonal support to form a closed force transmission path from the center to the four corners, it can further improve the versatility and overall rigidity of the support device, thereby preventing deformation of the window corners.
