Description

Technical Field

[0001] The utility model relates to the technical field of modular buildings, and particularly to a corner splicing structure of a modular building. Background Art

[0002] Due to its advantages such as convenient assembly, environmental protection and energy saving, modular buildings have been widely used in various building fields such as residential, office, education, medical, and commercial. Modular buildings can be divided into various structural forms such as planar, spatial, and hybrid according to different classification criteria, and different materials such as steel structures, concrete, wood, and composite materials are used. Modular buildings show broad application prospects in the fields of temporary buildings, civil buildings, industrial buildings, etc. The key to modular buildings lies in how to reliably connect between module units. Especially at the corner joints of modular buildings, since there are many corner connection objects, the corner connection structure is usually complex and the installation efficiency is low. The existing welding connections and rivet connections have complex processes, high technical requirements for workers, and there are also fire hazards. The existing bolt connections only consider interlayer connections and are not very suitable for transverse connections, and are not very suitable for the connections at modular corners.

[0006] Further, there are two side plates and they are perpendicular to each other.

[0007] Further, a structural reinforcement plate is provided in the middle of the operation space. The upper end of the structural reinforcement plate is connected to the first connecting plate, and the lower end is connected to the second connecting plate. The structural reinforcement plate divides the operation space into two sub-spaces, and partial side portions of the two sub-spaces are both open.

[0008] Further, there are two side plates, which are symmetrically arranged on both sides of the structural reinforcement plate.

[0009] Further, there are two groups of the first connection holes, which are respectively located on both sides of the structural reinforcement plate.

[0010] Further, a surrounding portion extending downward is provided at the bottom edge of the second connecting plate. The surrounding portion and the second connecting plate define a casting cavity with a lower opening.

[0011] Further, there are two side plates which are perpendicular to each other. The surrounding portion has four vertical side surfaces, and beam metal members are connected to two of the vertical side surfaces which are respectively opposite to the two side plates.

The horizontal splicing and vertical splicing enable modular buildings to be spliced in multiple levels and arrangements according to different needs, improving the application range of modular buildings. And partial side portions of the operation space defined by the first connecting plate, the second connecting plate and the side plates are open, so that tools can extend into the operation space to operate on the components (fasteners) penetrating into the operation space from the first connection holes and the second connection holes, thus facilitating the installation operation. By using the corner connectors, connection with vertically and horizontally adjacent modular buildings can be achieved at the corners without using different parts for horizontal connection and vertical connection, making the overall structure more concise, convenient for installation, and reserving an installation operation space, making the installation operation more convenient.

The first connecting hole 130 and the second connecting hole 150 are both formed on the side wall of the working space 160. Part of the side of the working space 160 is open, so that tools can extend into the working space 160 to operate on the components that penetrate into the working space 160 from the first connecting hole 130 and the second connecting hole 150.

As Figure 5 shown, the beam metal members 183 and the vertical metal structure 190 are steel bars, and concrete can be poured in the steel bar area to form a reinforced concrete structure, thus forming the cross beam and support column of the modular building 101.
