Description

Technical Field

[0001] The utility model relates to the technical field of cup mouth foundation construction, in particular to a cup mouth foundation core mold and a fixing structure thereof. Background Art

[0002] The cup-mouth foundation is a type of independent foundation. When the columns are prefabricated components, the foundation is often made into a cup-mouth shape, and then the columns are inserted and embedded in the cup-mouth, so it is also called a cup-shaped foundation. For the cup-mouth foundation, the core mold hole-making process is conventionally adopted. The traditional method generally uses a wooden formwork to make the cup-mouth foundation core formwork. The construction process is generally: ① excavation, ② foundation bottom plate reinforcement binding; ③ placement of the cup-mouth foundation core formwork and fixation; ④ cup wall reinforcement binding; ⑤ cup-mouth pedestal formwork support; ⑥ cup-mouth outer formwork support; ⑦ concrete pouring; ⑧ removal of the cup-mouth foundation core formwork.

[0003] The following problems exist in the prior art: 1. When the core mold of the cup mouth foundation is removed, it is generally necessary to use a crowbar to pry it apart. After the core mold is removed, it is generally damaged and cannot be used in a turnover manner, and the material utilization rate is low; 2. The core mold of the cup mouth foundation needs to be assembled with wooden templates and equipped with pull rods, internal supports, etc. for support and fixation during on-site construction. The construction process is complicated, and installation and reinforcement require a lot of manpower and material resources; 3. When removing the core mold, it is also easy to damage the cup mouth structure, affecting the construction quality. Utility Model Content
