Description

A special-shaped corner piece, a column with corner pieces and a prefabricated end frame structure

technical field

The invention relates to the field of construction, in particular to a special-shaped corner piece, a column with corner pieces and a prefabricated end frame structure.

Background technique

Existing standard corner fittings are mainly used in the field of containers, usually with a square structure, including hoisting holes, end holes and side holes, which are used for lifting, handling and fixing of containers. When a modular building needs to be built, the existing corner fittings are not suitable for connecting other building components, especially when building multi-storey buildings, the connection stability of the existing corner fittings is poor, and most corner fittings are threaded from top to bottom. It is not suitable for the assembly of high-rise buildings and is prone to danger.

In addition, the existing corner pieces are usually arranged flush with the column, so that when it is necessary to provide functional boards with certain functions such as thermal insulation boards and fireproof boards on the side and/or end faces of the formwork, the When used as a container, since the connection between the column, the beam and the corner piece must meet the standard container size, it can be transported by sea and land. If it exceeds a certain size, it cannot meet the transportation standard. Therefore, if additional function boards are set outside, the standard size will be exceeded, and the normal transportation of the container cannot be realized.

Furthermore, the existing house end frame usually has columns and beams connected to form a frame structure. When the house modules are assembled, they are usually spliced one by one at the construction site, which greatly increases the installation time, is time-consuming and laborious, and requires the use of There are many connecting parts, it is more laborious to find, and the installation process is extremely cumbersome. Alternatively, when the existing formwork type houses or the end frames of the containers are installed, they are first assembled in the factory to form a formwork structure, and then transported to the construction site for house lap jointing. However, this method still requires splicing each building component one by one in the factory, such as connecting the column with the short beam first, then connecting the column with the long beam, and then installing the floor slab to finally form a formwork structure. This method of splicing each building component in the factory still leads to cumbersome installation steps and significantly reduces the assembly speed. Furthermore, after the end frame structure is installed, some functional components, such as hinge seats, reinforcements, connectors, etc., will be installed according to requirements. If they are installed directly on site, the assembly speed will be further reduced. In addition, the existing columns are usually arranged in the same direction, which has poor functionality, inflexible connection and poor versatility.
