It is often used in large public buildings such as airport terminals and convention centers.

[0003] Currently, the steel structure connections used in hyperboloid space frame roofs are inconvenient to fix due to the curved surface characteristics, which affects the firmness and stability of the connections and can easily lead to a decrease in resistance and collapse after long-term use.

[0004] Therefore, a novel assembled steel component structure for hyperboloid space frame roofs is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an assembled steel component structure for hyperboloid space frame roofs, comprising a steel structure body, wherein an external plate is fixedly connected to the top and bottom of the steel structure body, and installation components with limit fixing are provided on the exterior of both sides of the steel structure body;

[0007] The mounting assembly includes a first limiting seat and a second limiting seat. The top and bottom of the inner sides of the first and second limiting seats are provided with built-in slots. The first and second limiting seats are respectively sleeved and installed on the outside of both sides of the steel structure body, and the two sides of the two sets of external plates are respectively inserted into the inside of the built-in slots. The two ends of the first and second limiting seats are provided with positioning holes, and the internal threads of the positioning holes are provided with mounting bolts.

[0008] As a further technical solution of this utility model, the inner end of the mounting bolt passes through the interior of the built-in slot and the interior of the outer plate in sequence, and the outer end of the mounting bolt is fixedly connected to a knob.

[0009] As a further technical solution of this utility model, the outer sides of the first limiting seat and the second limiting seat are both fixedly connected with supports, and the supports are symmetrically distributed about the vertical center line of the main steel structure.

[0010] As a further technical solution of this utility model, the outer ends of the outer plate are all fixedly connected with buffer and shock-absorbing outer plates, and grooves are provided on both sides of the front and rear ends of the outer plate.

[0011] As a further technical solution of this utility model, the front and rear sides of the buffer and shock-absorbing outer plate are fixedly connected with connecting frames, which are bent at right angles and fixedly connected inside the corresponding grooves.

[0012] As a further technical solution of this utility model, the front and rear ends of the main steel structure are both horizontally fixedly connected with an outer cover, and a protective plate is provided at the center of the inner part of the outer cover.

[0013] As a further technical solution of this utility model, both ends of the protective plate are fixedly connected with adhesive layers, and both sets of adhesive layers are bonded to the inner wall of the outer cover.

[0015] (1) By setting a first limiting seat, a second limiting seat, a support, an internal slot, a positioning hole and a mounting bolt, the first limiting seat and the second limiting seat are respectively sleeved and installed on the outside of both sides of the main body of the steel structure. The two sides of the outer plate are inserted into the corresponding internal slots by using the plug-in connection method. The outer plate enhances the firmness between the main body of the steel structure and the first limiting seat and the second limiting seat, effectively preventing the connection from loosening during the fixed installation. By adding positioning holes, the mounting bolts can be quickly moved through the inside of the first limiting seat and the second limiting seat, which plays a limiting and guiding role for the mounting bolts, making it easier to install and fix, and strengthening the safety of the connection.

They are fixed in the corresponding grooves by the connecting frames, which play a role in limiting and fixing the two ends of the buffer and shock-absorbing outer plates. This greatly enhances the stability between the two sets of buffer and shock-absorbing outer plates and the two ends of the main steel structure, prevents the buffer and shock-absorbing outer plates from shifting or falling, absorbs the impact force of the main steel structure, reduces the vibration transmitted to the main steel structure, and avoids cracking due to overload.

[0017] (3) By setting an outer cover, a protective plate and an adhesive layer, an outer cover is added to the surface of the main steel structure to place protective materials and play a safety protection role on the surface of the main steel structure. The protective plate enhances the load-bearing capacity of the main steel structure itself and protects it from external impact, corrosion, radiation, etc. It also has the functions of safety protection and environmental regulation. The adhesive layer firmly fixes the protective plate inside the outer cover to ensure the stability during the protection period. Attached Figure Description
