Prefabricated wall board positioning hole tool for concrete prefabricated component production line

Abstract

The invention belongs to the technical field of building products and particularly relates to a prefabricated wall board positioning hole tool for a concrete prefabricated component production line. The prefabricated wall board positioning hole tool comprises a base, a transverse support arm is arranged at the base in an extending mode, and a penetration hole is formed in the top end of the transverse support arm. The tool further comprises a positioning cylinder and a threaded sleeve, the top end face of the positioning cylinder is fixedly connected to the lower hole end face of the penetration hole in an abutting mode, and the positioning cylinder and the penetration hole are coaxially arranged / formed. An inner thread is arranged at a sleeve cavity of the threaded sleeve, a positioning bolt penetrates through the penetration hole and the positioning cylinder from top to bottom, and the positioning bolt and the threaded sleeve are matched in a threaded mode so as to enable the top endface of the threaded sleeve to abut against the bottom end face of the positioning cylinder. The height of the matching face of the threaded sleeve and the positioning cylinder is equal to or smallerthan the maximum grouting height of a mold cavity. According to the prefabricated wall board positioning hole tool for the concrete prefabricated component production line, when prefabricated wall bodies are formed, the equal height of the constructed prefabricated wall bodies can be ensured, and the coplanar later-period assembly requirement can be met, so that the assembly efficiency and accuracy of the prefabricated wall bodies can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of building products, and in particular relates to a prefabricated wall panel positioning hole tooling used in a concrete prefabricated component production line. Background technique [0002] In recent years, with the development of the economy, the construction industry has paid more and more attention to energy consumption and environmental pollution. The construction of traditional reinforced concrete structures in the field of construction often adopts on-site wet construction. This construction method not only consumes a large amount of wood as bottom formwork and support materials, but also consumes a lot of energy, and construction efficiency is low. It takes a long time, produces noise and dust, and has great pollution to the surrounding environment. Therefore, in recent years, the construction field has begun to introduce the concept of modular houses. Modular houses are different from traditiona...

Problems solved by technology

However, due to the complex construction environment on site, the flatness of the floor slab as the foundation and even the ground is questionable, which brings troubles to the construction operation on site

In addition, during the grouting process of closing the warehouse and when the cement mortar hardens, corresponding internal stress will also be generated, which may also cause changes in the positions of two adjacent prefabricated walls. To achieve this, it not only occupies a large area, but also has an adverse impact on the construction cost and construction time.
