Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of assembled buildings, and in particular relates to an assembled building splicing structure. Background Art
[0002] With the rapid development of the modern construction industry, prefabricated buildings, as an efficient and environmentally friendly construction method, are gradually becoming a mainstream trend in the industry. The core of prefabricated buildings lies in the standardized, modular production of prefabricated components and their rapid on-site assembly. This model not only significantly shortens the construction period and reduces labor costs, but also improves the overall quality and construction safety of buildings. However, despite the many advantages of prefabricated buildings, in practice, issues such as the structural strength, thermal insulation performance, and construction efficiency of prefabricated components remain key factors hindering their further development.
[0003] Traditional precast concrete panels, the primary structural element of prefabricated buildings, often have a simple design and lack sufficient internal support structures, resulting in insufficient overall strength and difficulty meeting the high load-bearing and seismic performance requirements of high-rise buildings or complex structures. Furthermore, the connection between the precast concrete panels and the insulation material presents problems. A common practice is to glue an insulation layer onto the surface of the precast panels. This method is not only cumbersome to construct, but also difficult to ensure the bond strength between the insulation layer and the precast panels. Over time, this method is prone to problems such as falling off and cracking, seriously affecting the building's insulation performance and durability. Utility Model Content
