Description

Technical Field

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

[0002] Modular buildings refer to lightweight steel structure building modules that use one or more building units as prefabricated modules, which are prefabricated in factories or assembled on site and have functional functions. After the modules are installed to form a single cabin, they are often assembled according to actual requirements to form a multi-cabin structure to adapt to different scenarios. Figure 1 and Figure 2 shown.

[0003] The main construction method currently used in the market is to prefabricate building beams and columns and assemble them on-site. This method has drawbacks such as a large number of parts, which can easily lead to confusion during on-site construction; a long and complex installation process; construction is easily affected by weather such as rain and snow; and there are many structural nodes, which can lead to poor building integrity.

[0004] After the above installation is completed to form a single cabin, it is often necessary to assemble it according to actual requirements to form a multi-cabin structure due to functional requirements. Regardless of whether it is prefabricated separately or as a whole, there are often problems in the cabin assembly process such as difficult nodes to handle and difficult installation and removal of connection nodes. In the process of assembling a multi-cabin structure, since each module is prefabricated in the factory, there are problems with the upper and lower and left and right multi-beam and multi-column combination connections during on-site splicing, which often lead to disadvantages such as difficult construction and handling of connection nodes and difficulty in ensuring connection strength. Utility Model Content

[0005] The purpose of the utility model is to provide a modular steel structure intelligent house corner 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 solution: a modular steel structure intelligent house corner column connector, comprising a horizontal cross-shaped steel plate for connecting steel beams, wherein the four corners of the horizontal cross-shaped steel plate are provided with a plurality of elliptical bolt holes;

[0007] An upper vertical plate for connecting steel columns, wherein the upper vertical plate is fixedly connected to the left side of the upper surface of the horizontal cross-shaped steel plate;

[0008] The lower vertical plate is used to connect the steel column. The lower vertical plate is fixedly connected to the middle part of the lower surface of the horizontal cross-shaped steel plate. The upper and lower vertical plates are also provided with a number of elliptical bolt holes to facilitate the subsequent installation of steel structure bolts.

[0009] Horizontal cross-shaped steel plates, upper vertical plates and lower vertical plates are used to combine steel beams and steel columns horizontally and vertically, making the modular steel structure combination more flexible.

[0010] Furthermore, the horizontal cross-shaped steel plate includes a main square plate, a right square plate, and a left square plate. The right square plate and the left square plate are integrally formed with the main square plate, and the width of the right square plate is smaller than that of the left plate.

[0011] Furthermore, a first stiffening rib is fixedly connected between the horizontal cross-shaped steel plate and the upper vertical plate, and two second stiffening ribs are fixedly connected to the lower surface of the horizontal cross-shaped steel plate. The two second stiffening ribs are fixed on the left and right sides of the lower vertical plate, thereby improving the stability of the connection between the upper and lower vertical plates and the main square plate, and making it less prone to deformation and bending problems.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) After the steel beams and columns are in place, they can be quickly installed and removed by simply placing them in the corresponding positions of the corner column connectors using high-strength structural bolts. This allows for different functionalities while allowing for the free horizontal and vertical combination of steel beams and columns between modules, greatly reducing the number of single components and construction processes, and flexibly adapting to various space requirements. Elliptical bolt holes are provided on the upper and lower vertical plates and the horizontal cross-shaped steel plates to facilitate construction while allowing for a certain degree of structural deformation and construction errors.

[0014] (2) The combination of the upper vertical plate, the lower vertical plate, the horizontal cross-shaped steel plate, the second stiffening rib, and the first stiffening rib reduces the number of structural components, the size of the node, and the deadweight of the node, thereby achieving a lightweight structural design. At the same time, the second stiffening rib and the first stiffening rib increase the bending stiffness of the node and improve the strength of the steel structure splicing.

[0015] (3) Compared with conventional construction methods, this solution reduces the number of construction processes. The combined design of corner column 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. BRIEF DESCRIPTION OF THE DRAWINGS

The stiffening ribs also further improve the bending stiffness of the node. The steel column connected to the upper vertical plate 1 and the lower vertical plate 2 has a groove, so that the steel column can be inserted into the second stiffening rib 7 and the first stiffening rib 8. The elliptical bolt holes 6 left on the upper vertical plate 1 and the lower vertical plate 2 are used to install and fix the steel column. The four steel beams are fixed to the horizontal cross-shaped steel plate 9 with bolts.
