Description

Technical Field

[0001] The present invention relates to a connecting piece, specifically a connecting piece for connecting and combining an assembled house frame, belonging to the technical field of building accessories. Background Art

[0002] Due to the advantages of rapid construction, fast construction speed, good adaptability to the ground environment, high safety, and recyclability, assembled houses are widely used in low-rise villas, assembled customized houses, tourism resorts or camp hotels and other fields. Assembled houses generally first build a steel structure frame, and then install structures such as the ground, walls, floors, and roofs. The traditional assembled houses mainly have the following disadvantages when being built: when installing the frame, welding or direct screw fixing is generally used at each docking position. The welding method is complex to operate, requires professional welders, and is troublesome to disassemble, while the structural stability of the direct screw fixing method is not high enough; welding cannot be reused, resulting in waste of resources.

[0003] The patent with the authorization announcement number: CN209837290U discloses a connecting piece for assembling an assembled house frame, and specifically discloses: including a main kit 1 with a square frame structure. The main kit 1 is a non-closed structure with a longitudinal notch on the side wall, so that the main kit 1 has a certain shrinking and opening space, enabling the column to pass through smoothly and facilitating disassembly; the inside of the main kit 1 is a through hole with openings at both ends. A plurality of screw holes 7 are provided on the side wall of the main kit 1. The column forming the house frame passes through the through hole of the main kit 1, and the main kit 1 is fastened to the column with screws passing through the screw holes 7; a first connecting arm 2 and a second connecting arm 3 are provided on the side wall of the main kit 1. The first connecting arm 2 and the second connecting arm 3 respectively extend vertically outward from two different side walls of the main kit 1. Screw holes 7 are provided on both the first connecting arm 2 and the second connecting arm 3 for the cross bar forming the house frame to be inserted into the first connecting arm 2 or the second connecting arm 3 and tightened and fixed by screws passing through the screw holes 7, so that the cross bar and the column are connected into a frame structure through this connecting piece; the first connecting arm 2 and the second connecting arm 3 form a connecting piece of an integral assembly with the main kit 1. Both the first connecting arm 2 and the second connecting arm 3 are hollow structures. Side water and electricity holes 8 are provided on each side wall of the main kit 1. The through holes of the first connecting arm 2 and the second connecting arm 3 are aligned with the side water and electricity holes 8 to form an access structure for water and electricity lines, which can facilitate the installation of water and electricity very conveniently, and are hidden inside the frame to prevent damage and are beneficial to the beauty of the house.

[0004] It can be seen from the above content that: both the first connecting arm 2 and the second connecting arm 3 of the main kit 1 are fixedly connected to the main kit 1, cannot be disassembled, are not convenient for reuse, and need to be prefabricated in advance, which is troublesome to transport, and can only be applicable to installations with columns, and the applicable range is relatively narrow.
