Tool and construction method used for reserving reserved hole of stand pipe
The invention relates to the technical field of stand pipe installation, and particularly discloses a tool used for reserving a reserved hole of a stand pipe. The tool comprises a circular-truncated-cone-shaped mold body installed on a structural plate bottom mold, and a locking mechanism which is used for locking the mold body and the structural plate bottom mold. The invention further discloses a construction method used for reserving the reserved hole of the stand pipe. The construction method specifically comprises the following steps that the tool is installed at the corresponding position of the stand pipe; structural slab concrete pouring is carried out; the tool is taken out, and the stand pipe is installed at the reserved hole; and a groove between the outer side wall of the stand pipe and a structural plate is poured by adopting expansive concrete. According to the tool used for reserving the reserved hole of the stand pipe, the circular-truncated-cone-shaped mold body structural plate is installed, then structural plate concrete pouring is carried out, an included angle is formed between the inclined face of the reserved hole and the stand pipe, when secondary concrete pouring is carried out, form erecting does not need to be carried out again, the included angle formed between the inclined face of the reserved hole and the stand pipe further enables the stress of the secondary concrete to be stable, and therefore the secondary plugging concrete and the inclined face of a concrete structure can be bonded more firmly.
本发明涉及立管安装技术领域，具体公开了一种用于立管预留洞预留的工装，包括圆台状且安装在结构板底模上的模具本体、以及用于锁紧模具本体与结构板底模的锁紧机构。还公开了一种用于立管预留洞预留的施工方法，具体包括以下步骤：将工装安装在立管对应的位置上；结构板混凝土浇筑；取出工装，在预留洞位置安装立管；采用膨胀混凝土浇筑立管外侧壁与结构板之间的凹槽。本发明通过安装圆台状的模具本体结构板，然后进行结构板混凝土浇筑，使得预留洞斜面与立管形成夹角，在进行二次混凝土浇筑时，不需要再次进行支模；预留洞斜面与立管形成夹角也将使得二次混凝土受力稳定，能够保证用于二次封堵混凝土与混凝土结构斜面之间粘接更牢固。
