Description

Technical Field

[0001] The utility model relates to the technical field of sign foundations, in particular to a prefabricated assembled sign foundation. Background Art

[0002] At present, cast-in-place concrete is generally used for sign foundations in the flight area. When constructing cast-in-place concrete foundations in operating airports, there is a safety risk of FOD (foreign objects in the airport flight area), and due to security inspections, the waiting time for concrete is too long, affecting the quality of concrete pouring. Moreover, to ensure the wind resistance strength of the sign, the designed volume of the foundation is large. For large precast foundations, large-tonnage cranes and transport vehicles are required, resulting in high construction costs and increased vehicle management difficulties. Therefore, the precast sign foundation is designed as an assembled foundation.

[0003] For example, the Chinese utility model patent discloses a precast concrete assembled combined iron tower independent foundation (publication number CN210177532U), which includes a core foundation block and a splicing foundation block. The core foundation block and the splicing foundation block are made of precast concrete and are rectangular in shape. Two groups of grooves and two groups of protrusions matching the grooves are respectively arranged on the sides of the core foundation block and the splicing foundation block. The adjacent protrusions are inserted into the grooves to connect the adjacent core foundation block and the splicing foundation block together. It can effectively reduce the large amount of traditional foundation construction and reduce the construction difficulty.

[0004] However, when the inventor specifically implemented this device, it was found that there were the following defects: it was difficult to splice and align between the splicing foundation blocks and between the core foundation and the splicing foundation blocks, the construction efficiency of the sign foundation needed to be further improved, and the structural strength of the formed foundation needed to be further enhanced.
