Description

Technical Field

[0001] The present application relates to the technical field of PC prefabricated building construction, specifically a prefabricated structural support for civil construction. Background Art

[0002] PC sandwich insulation panels are precast concrete components used in building exterior walls, serving both thermal and structural functions. Common PC sandwich insulation panels typically consist of an outer fine-grain concrete protective layer, an inner concrete layer, and an internal insulation layer. This three-layer structure not only ensures the wall's load-bearing capacity but also significantly enhances its thermal insulation effectiveness. Using specialized connectors, these precast panels can be combined to form a complete exterior wall system.

[0003] During the construction of PC component sandwich insulation board, after its hoisting is completed and before grouting and fixing, it is necessary to use multiple temporary inclined support rods to fix it to the roof board. During the specific construction process, it is necessary to pre-embed positioning steel bars on the roof board, and then install the inclined support temporary fixings on the PC component sandwich insulation board. Finally, use the inclined support rods to connect the pre-embedded positioning steel bars with the supporting temporary fixings, so as to achieve the fixation of the PC component sandwich insulation board. Using the above fixing method, it is necessary to pre-embed multiple positioning steel bars on the roof board in advance. After the construction is completed in the later stage, these positioning steel bars need to be cut off one by one, which is very inconvenient to operate. At the same time, the existing support rods are time-consuming and labor-intensive to adjust during installation and construction, and the disassembly and assembly efficiency is relatively low.
