[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] The present invention details the above technical solution through the following embodiments:

[0024] Example 1: As Figure 1-2 As shown, a building shell structure keel device includes a base, secondary keel, fasteners, adjusting bolts, and a main keel. The base is installed in a concrete foundation, and the main keel is positioned above the base. The base and the main keel are fixed together by ordinary welding. One end of the secondary keel is positioned in an adjusting groove, and the adjusting bolt passes through the connecting hole and adjusting groove on the main keel from the inside and connects to the secondary keel. The fasteners are positioned on the outside of the secondary keel and are threadedly connected to the main keel.

[0025] A supporting scaffold is erected under the main keel. After the supporting scaffold is erected, the curved template is installed. The fabrication of the main keel requires the use of CAD and Rhino model to calculate the spatial coordinates of each span. The main keel is then fabricated by laying out the actual space in the project based on the calculated space.

[0026] The main keel has an arc-shaped structure with an I-shaped cross-section. Multiple connection holes are provided on the main keel for connection with secondary keels. Internal reinforcing ribs are incorporated into the main keel to enhance its load-bearing capacity and bending resistance. The main keel is constructed of high-strength steel to ensure its load-bearing capacity and structural strength. Adjusting bolts are made of stainless steel to prevent rust and improve the reliability and durability of the connection.

[0027] The secondary keel is a straight rod with a connector at one end that connects to the adjustment groove. The connector is then bolted to the connection hole of the main keel. Both the main and secondary keels are manufactured using mold forming and machining processes to ensure dimensional accuracy and surface quality. Reinforcing ribs are welded to the inside of the main keel to ensure a secure connection.

[0028] The main keel and secondary keel are detachably connected by connectors and connecting holes, which facilitates flexible assembly according to the shape and size of the building shell structure.

[0029] To further improve the adaptability of the device, an adjustment mechanism is also provided. The adjustment mechanism includes an adjustment groove and an adjustment bolt. By moving the adjustment bolt within the adjustment groove, the position of the secondary keel on the main keel can be adjusted.

[0030] Example 2: Figure 1-2 The following are the installation steps for a building shell structure keel device:

[0031] First, determine the installation location and curvature of the main keel according to the design requirements of the building shell structure. Then, install the main keel onto the building structure using embedded parts or other fixing methods.

[0032] Then, according to actual needs, the adjusting bolts are passed through the connecting holes and adjusting grooves on the inner side of the main keel and connected to the secondary keel connector. The position of the secondary keel in the adjusting groove is adjusted to match the formwork or other supporting structure of the building shell structure.

[0033] Finally, use the fastener at the other end of the secondary keel to fix it to the main keel, ensuring the stability and reliability of the entire keel assembly.

[0034] During installation, ensure bolt connections are secure to prevent loosening. Regularly inspect the connections and structural integrity of the keel system; repair or replace any damaged or deformed parts promptly. Disassembly should be performed in reverse order, taking care to protect the keel and connecting components for reuse.

[0035] The above descriptions are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
