Description

Technical Field

[0001] The utility model relates to the technical field of steel structure assembled buildings, in particular to a center column connector for a modular steel structure intelligent house. Background Art

[0002] Modular buildings refer to low-rise or multi-story buildings that are made by assembling and connecting one or more building units as prefabricated modules, which are prefabricated in a factory or assembled on site and have functional light steel structure building module units.

[0003] The connection points of modular buildings are crucial. Without reliable joints, the structure composed of multiple modules will deform, break, or even collapse. Currently, the predominant construction method in the market involves prefabricating components such as beams and columns, followed by on-site assembly. This approach presents drawbacks such as a large number of components, which can lead to confusion during on-site construction; a long and complex installation process; susceptibility to weather conditions such as rain and snow; and a large number of structural joints, which can compromise building integrity.

[0004] After the above installation is completed to form a single cabin, it is often necessary to assemble it into a multi-cabin structure according to actual requirements due to functional requirements to adapt to different scenarios, such as Figure 1 and Figure 2 Whether prefabricated individually or as a whole, the cabin assembly process often faces problems such as difficult joint handling and difficulty in installing and removing connection nodes. In the process of assembling a multi-cabin structure, since each module is prefabricated separately in the factory, there are problems with the upper and lower, left and right multiple beam and column combinations during on-site splicing. This often leads to disadvantages such as difficult construction and handling of connection nodes, difficulty in ensuring connection strength, and poor practicality and comfort. Utility Model Content

[0005] The purpose of the utility model is to provide a modular steel structure intelligent house center column connector to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a modular steel structure intelligent house center column connector, comprising a central connector for connecting steel beams in four directions of a horizontal plane, wherein a plurality of elliptical bolt holes are provided on the surface of the central connector;

[0007] Auxiliary connector for connecting steel columns in two directions of the vertical plane. The surface of the auxiliary connector is also provided with a number of elliptical bolt holes to facilitate the subsequent installation of steel structure bolts;

[0008] The auxiliary connecting piece passes through the central connecting piece and is fixedly connected to the central connecting piece, so that the modular steel structure composed of steel beams and steel columns can be freely combined.

[0009] The central connecting member is a cross-shaped steel plate, the auxiliary connecting member is a straight-line steel plate, and the straight-line steel plate is divided into an upper vertical plate and a lower vertical plate by the central connecting member. Stiffening ribs are fixedly connected between the central connecting member and the auxiliary connecting member. A connecting hole is provided on the surface of the central connecting member, and the auxiliary connecting member is fixedly connected inside the connecting hole.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] (1) After the steel beams and columns are in place, they can be quickly installed and dismantled by simply placing them in the corresponding positions of the connectors using high-strength structural bolts. This allows for different functionalities while allowing for the horizontal and vertical free combination of steel beams and columns between steel modules, significantly reducing the number of single components and construction processes, making them flexible and adaptable to a variety of space requirements. Elliptical bolt holes are opened on the I-shaped steel plates and cross-shaped steel plates, facilitating construction while allowing for a certain degree of structural deformation and construction errors.

[0012] (2) The combination of upper vertical plate, lower vertical plate, cross-shaped steel plate and stiffening ribs reduces the number of structural components, reduces the node size, and reduces the node weight, thereby achieving a lightweight structural design. At the same time, the stiffening ribs further increase the bending stiffness of the node and improve the strength of the steel structure splicing.

[0013] (3) Compared with conventional construction methods, this solution reduces the number of construction processes. The combined design of connectors and elliptical bolt holes allows for quick installation and assembly at the point of use, reducing the total transportation volume, increasing the transport volume per vehicle, and lowering transportation costs and risks. It also reduces the lifting weight of a single hoist in special locations and complex areas, making construction more convenient.

[0014] (4) The node connection method of this solution provides structural safety and comfort for the multi-cabin combination, breaking the disadvantages of single cabin and single use function of conventional cultural and tourism smart residences, and adapting to the current trend of large families and company team building.
