Description

Technical Field

[0001] This utility model belongs to the field of expansion joint construction technology, and in particular relates to prefabricated assembled expansion joint construction templates. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories are processed and manufactured in factories, transported to the construction site, and assembled on-site using reliable connection methods.

[0003] During the assembly of prefabricated buildings, gaps appear between the building components. At the joints, cutting tools are typically used to cut the gaps, and then a vibrating head is used to break up the concrete to form expansion joints. Then, steel plates are placed in the gaps and welded to the pre-embedded reinforcing bars. Finally, concrete is poured. However, this construction method is relatively complex and increases the difficulty of forming expansion joints. To address this, we propose a construction template for prefabricated expansion joints that facilitates the formation of expansion joints and overcomes the shortcomings of existing technologies.
