Abstract
Description
Technical Field
[0001] This utility model relates to a device for quick connection between aluminum alloy templates and wooden templates, belonging to the field of template connection technology. Background Technology
[0002] Aluminum alloy formwork boasts advantages such as light weight, high strength, excellent forming effect, and high reusability, while wooden formwork offers low cost, ease of processing, and adaptability to complex shapes. Both are widely used in construction. Sometimes, to meet the needs of different construction sections, both types of formwork are used simultaneously. However, existing connection methods have several problems. The currently common method involves an L-shaped connector on the back of the connection between the aluminum alloy and wooden formwork. This connector is fixed to the wooden formwork with screws, and then the other side of the connector is fixed to the aluminum alloy formwork with pins. However, this process is cumbersome, requiring significant time for positioning and tightening, thus delaying construction progress. Utility Model Content
