Description

Technical Field

[0001] The utility model relates to the technical field of building construction layer-adding connection structures, in particular to a layer-adding connection structure for expressway building construction projects. Background Art

[0002] As the construction of expressways across the country is accelerated, new expressway projects are becoming less and less, while maintenance projects are increasing. The functions of existing buildings on expressways are difficult to meet the use requirements of existing units, but demolition and reconstruction will inevitably cause great economic waste and serious environmental pollution. Therefore, adding floors to existing buildings to meet the functional requirements of existing units is an important part of the expressway industry.

[0003] At present, most of the existing buildings on expressways are masonry and concrete structures. When adding layers to the roofs, concrete components are usually used. Although the appearance is consistent with the original structure and it is durable, the connection between the two is usually made by embedding steel bars. For the connection of larger components, the steel bars are larger, and the original structure often cannot meet the requirements of steel bar anchoring. In addition, due to the shrinkage of the concrete itself, there is always a risk of cracks at the connection.

[0004] In order to solve the above problems, people began to study the methods suitable for adding floors to existing buildings in highway building projects. Steel structures are gradually being promoted as a form of adding floors to concrete buildings due to their advantages such as light weight, small earthquake effects, and no damage to the original house structure. However, when using steel structures to add floors to concrete building roofs, due to the differences between the two different structural systems, when the two are integrated into one, there will be problems such as stiffness and mass mutations at the connection between the new and old structures, resulting in an unstable connection between the two. Therefore, we designed a connection structure that can strengthen the stability of the connection between the steel structure and the original structure, which can improve the stability of the connection between the steel structure and the original structure and ensure a close connection between the two. Utility Model Content
