Description

Technical Field

[0001] The utility model relates to the field of steel structure building components, in particular to an irregular corner connection structure. Background Art

[0002] Beyond practical needs, the public's aesthetic standards are also raising increasingly high standards for architectural form. Large buildings, due to their large scale, have greater tolerances for shape and require a wide variety of construction methods. However, for smaller buildings, there is still room for improvement in lightweight, simple, and small-scale construction methods for unique shapes. In panel-type prefabricated buildings, irregular corner connections between panels are typically filled with wooden wedges and secured with screws.

[0003] The above treatment method still has some drawbacks. First, it is not convenient to produce wooden wedges on site, and the construction process is not well prepared for emergencies or temporary changes. Second, the service life of wood and steel differs, and this difference in the lifespan of various building materials may create maintenance risks. Third, the use of wood in key areas such as joints increases the complexity of structural fireproofing, which is detrimental to the structure's fire resistance. Utility Model Content

[0004] The purpose of the utility model is to provide an irregular corner connection structure to solve the above problems, which can realize the connection of any obtuse angle, ensure the structural strength, and is easy to manufacture on site with good precision.

[0005] Technical solution: The utility model provides an irregular corner connection structure, which is composed of two connecting components. The connecting component is an L-shaped connecting member, which is divided into a connecting plate and an extended edge. The two connecting components have exactly the same structure. The connecting component connects adjacent building modules, and the length a of the connecting component is equal to the thickness of the structural layer of the building module, which can ensure that the connection will not protrude, facilitating the construction of the building surface layer.

[0006] Furthermore, in the above-mentioned irregular corner connection structure, the connection member is directly formed by cutting cold-bent thin-walled U-shaped steel.

[0007] Furthermore, in the above-mentioned irregular corner connection structure, the cross-sectional height of the cold-bent thin-walled U-shaped steel used in the connecting member is the same as the specification of the U-shaped steel used in the connected building module structure, and the connecting member can be quickly and conveniently manufactured with high precision at the construction site.

[0008] Furthermore, in the above-mentioned irregular corner connection structure, the length of the two sides of the connection plate adjacent to the building module is a, and the angle between the two sides of length a is cut according to the required connection angle.

[0009] Furthermore, in the aforementioned irregular corner connection structure, the connecting member has a length a equal to the thickness of the building module structural layer, which is used as the hypotenuse. Based on the right triangle theorem, a connecting member of the maximum size b that can be cut from a U-shaped steel with a width a is obtained. This maximizes the size of the cut connecting plate and its area, thereby improving the structural strength of the connected structure.

[0010] Furthermore, in the above-mentioned irregular corner connection structure, when the connection plates are connected to each other, the inner sides of the connection plates are fitted together.

[0011] Furthermore, in the above-mentioned irregular corner connection structure, the connection plates are connected and fixed by self-tapping and self-drilling screws, and the extended edges are connected to adjacent building modules by self-tapping and self-drilling screws.

[0012] It can be seen from the above technical solution that the utility model has the following beneficial effects: the irregular corner connection structure described in the utility model has a connection part with a strength comparable to that of the main structure, is easy to manufacture, and is easy to control in terms of precision and quality. It does not occupy additional space and is easy to use. The two L-shaped connectors can be first connected to their respective building modules, and then the two L-shaped connectors can be connected on site; or the two L-shaped connectors can be first connected to form a corner connection structure, and then the building modules and the corner connection structure can be connected on site.
