Description

Technical Field

[0001] The utility model relates to the technical field of aluminum formwork pre-embedded construction, and more specifically, to an aluminum formwork wire tube pre-embedded hole-free positioner. Background Art

[0002] Aluminum formwork is a new generation of formwork system, following the emergence of wood and steel formwork. Designed according to modularity and extruded using specialized equipment, aluminum formwork can be freely combined to accommodate various structural dimensions. Currently, aluminum formwork systems are widely used in residential and office buildings. Aluminum formwork offers advantages such as a short construction cycle, high reuse rates, low average cost of ownership, and ease of construction and high efficiency.

[0003] A common problem with commercial aluminum formwork is that after initial positioning and drilling, the aluminum formwork at the floor openings can easily become misaligned during subsequent floor installation, requiring secondary drilling and causing grout leakage. Furthermore, during the aluminum formwork removal process, wire conduits can be easily broken at their roots, making it difficult to reconnect the secondary piping. This further increases the scrap rate and loss of the aluminum formwork, significantly increasing material and labor costs. To address this issue, utility model patent publication number CN215830012U proposes a hole-free wire conduit locator for the bottom of an aluminum formwork beam. The device comprises a base plate that is detachably fixed to the aluminum formwork. The base plate is fixedly connected to the base plate, with at least one sleeve having an outer diameter equal to the inner diameter of the wire conduit connector embedded in the crossbeam. The base plate is secured to the aluminum formwork via fasteners. The base plate has countersunk holes for fasteners. The aluminum formwork has a recess for the base plate, ensuring that when the base plate is placed in the recess, its upper surface is flush with the upper surface of the aluminum formwork. This device has a simple structure and is easy to install. However, the installation position of the base plate on the aluminum template is fixed and cannot be fine-tuned according to the position of the wire tube. It has poor adaptability and is not convenient for turnover use. Utility Model Content
