Description
Technical Field
[0001] The utility model relates to the technical field of connection structures of precast concrete box houses, and specifically relates to a connection structure of a precast concrete box house. Background Technique
[0002] A precast concrete box house (also known as a precast container house or a modular concrete house) is a concrete house structure prefabricated by using industrialized production methods. They usually adopt modular design, and each module is an independent and complete building unit, including the walls, floors, roofs of the house and necessary internal facilities.
[0003] For some existing box houses, there is no connection form, relying only on the self-weight of the box body, lacking the overall stability of the connection; or some horizontal connections are to reserve lapped bars at the connection, and then cast-in-place concrete is used for connection after installation. This requires separate formwork and pouring, which prolongs the construction period and is a wet operation. The construction site is very dirty and messy, and there is interference between the reserved lapped bars, affecting the installation efficiency; or some vertical connections are grouting sleeve connections. Grouting sleeve connections have high requirements for the accuracy of the installation space. After installation, it is not easy to ensure the grouting density, and there are cavity situations. Moreover, grouting materials need to be prepared on site, and the grouting process is cumbersome, increasing the construction period. Therefore, we propose a connection structure of a precast concrete box house. Content of the Utility Model
