Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to an assembled prefabricated pipe well floor structure. Background Art

[0002] In the construction of houses, the floor slabs at the pipe shafts are usually constructed by reserving steel bars and then pouring holes for secondary pouring, or by pre-embedded casings cast in situ. However, there are some problems with this method: (1) Although the construction method of reserving steel bars and re-casting holes can ensure the positioning accuracy of the pipe casings, it is necessary to support or hang the formwork for pouring after the pipe construction in the pipe shaft is completed, which is not conducive to the convenience and safety of construction. In addition, the working surface is narrow and vibration is inconvenient during pouring, which makes it difficult to ensure the construction quality, and quality problems such as water leakage are prone to occur in the later stage. (2) Although the construction method of pre-embedded casing cast in situ can ensure integrity, when the floor height is high and the number of vertical pre-embedded floors is large, the error of pre-embedded casings on each floor may accumulate as the number of floors increases, which may easily lead to insufficient accuracy and fail to meet the requirements of pipeline construction. It is necessary to chisel and repair, which wastes manpower and material resources and affects the construction progress.

[0003] At present, there is relatively little research on prefabricated pipe well floor slabs. The patent document with publication number CN217679923U proposes an assembled pipe well floor slab structure, which prefabricates the pipe well floor slab, casing, and guide wall together, and reserves lifting rings and steel bars. The patent document with publication number CN214942026U proposes a pipe well prefabricated plate, which is mainly constructed by prefabricating GRC plain concrete slabs in the factory and reserving removable holes.

[0004] There are still some deficiencies in the current research on prefabricated pipe shaft floor structures: although some prefabricated pipe shaft floor structures have solved the problems of casing positioning accuracy and secondary pouring difficulties, they are produced by full factory prefabrication and need to be processed in the factory, which has deficiencies in construction costs, coordination of processing progress and on-site progress, etc. On the other hand, although the full prefabrication method has better integrity, when the floor is high and the working surface is large, the lifting weight is large, and there are higher requirements for vertical transportation lifting equipment, and the scope of application is limited.

[0005] Therefore, it is necessary to design an assembled prefabricated pipe well floor structure. Utility Model Content
