Description

Technical Field

[0001] This utility model relates to the technical field of dome steel structure installation, and in particular to an environmentally friendly new dome steel structure installation structure. Background Technology

[0002] As the main load-bearing structure of a building, the dome steel structure effectively bears and distributes the building's weight and external loads, such as wind and snow pressure, ensuring the building's stability and safety. Simultaneously, the dome steel structure possesses good seismic performance, mitigating the building's vibration response and protecting its safety during natural disasters such as earthquakes through its deformation and energy dissipation capabilities. Furthermore, the installation structure of dome steel structures typically employs modular and prefabricated installation methods, significantly improving construction efficiency, shortening the construction period, and reducing construction costs.

[0003] The existing dome steel structure installation structure mainly consists of a spatial grid structure main structure, support system, connection nodes, lifting and installation equipment, and detailed design components. For example, Chinese patent CN222009193U, entitled "An Environmentally Friendly Novel Dome Steel Structure Installation Structure," describes a new type of environmentally friendly dome steel structure installation structure. This structure incorporates a fastening mechanism. After the connecting sleeve and connecting plate pass through the calibration groove, the irregular groove and connecting protrusions cause the connecting plate to deflect, allowing the cross-shaped assembly of the connecting sleeve and connecting plate to provide a larger contact area when locking the supporting and connecting steel frames. This, combined with the elastic element and top plate, better presses the connection between the supporting and connecting steel frames when the bolts are tightened, thus improving the dome structure's wind resistance and facilitating installation and disassembly while providing better deformation resistance. However, during use, the cross-shaped connecting sleeve and connecting plate require corresponding grooves to be cut at specific locations for insertion and connection. These grooves cause significant stress concentration on the workpiece, reducing its overall load-bearing capacity and hindering its overall use. Therefore, this application provides an environmentally friendly novel dome steel structure installation structure to meet these requirements. Utility Model Content

[0004] The purpose of this application is to provide an environmentally friendly new type of dome steel structure installation structure, which solves the problem of excessive stress concentration caused by large-sized troughs in the prior art, and achieves the goal of reducing stress concentration and thus improving load-bearing capacity.

[0005] To achieve the above objectives, this application provides the following technical solution: an environmentally friendly novel dome steel structure installation structure, comprising a dome frame and a supporting steel frame disposed below the dome frame, wherein a connecting steel frame is disposed below the supporting steel frame, both the supporting steel frame and the connecting steel frame are provided with positioning holes, and guide grooves are provided around the positioning holes, the guide grooves are inserted into the positioning holes, and a first reinforcing plate is fixedly connected to the top of the guide grooves, and an L-shaped plate is disposed below the guide grooves, both the supporting steel frame and the connecting steel frame are provided with connecting holes, and connecting grooves are provided on the first reinforcing plate and the second reinforcing plate, connecting pins are inserted into the connecting holes and connecting grooves, and threaded sleeves are provided at the top and bottom of the connecting pins.

[0006] Preferably, the cross-sections of the guide groove and the guide plate are both trapezoidal, and the guide groove and the guide plate are compatible. The guide plate is slidably connected inside the guide groove, and both the guide groove and the guide plate have rounded corners.

[0007] Preferably, both the supporting steel frame and the connecting steel frame are provided with a recessed groove, and the recessed groove and the connecting hole are located on the same central axis. The recessed groove is provided with an internal threaded sleeve, and the thread structure on the internal threaded sleeve is adapted to the connecting pin.

[0008] Preferably, both sides of the first reinforcing plate and the second reinforcing plate are respectively provided with L-shaped plates and insertion slots. The side wall of the L-shaped plate is provided with a plurality of electric push rods, and the free ends of the plurality of electric push rods are fixedly connected to the same insertion member, and the insertion member is adapted to the insertion slot.

[0009] Preferably, the side wall of the L-shaped plate is provided with a bending groove, and the electric push rod is disposed inside the bending groove.

[0010] Preferably, the bottom of the positioning pin has an installation cavity, and the installation pin is slidably inserted into the cavity, and the bottom of the installation pin is fixedly connected to the top of the L-shaped plate.

[0011] Preferably, both the supporting steel frame and the connecting steel frame have internal reinforcement structures.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] This utility model has a reasonable structure. By setting a first reinforcing plate and a second reinforcing plate, the positioning pin, the first reinforcing plate, and the second reinforcing plate effectively form an I-shaped structure, thereby fixing the supporting steel frame and the connecting steel frame inside the I-shaped structure, ensuring the relative stability between the supporting steel frame and the connecting steel frame, and avoiding the possibility of displacement during use. At the same time, the first reinforcing plate and the second reinforcing plate will also be in contact with the supporting steel frame and the connecting steel frame, so that when an external load is applied, it can be applied to the first reinforcing plate and the second reinforcing plate, allowing the first reinforcing plate and the second reinforcing plate to distribute the load evenly to the supporting steel frame and the connecting steel frame, thereby reducing the occurrence of uneven load on the supporting steel frame and the connecting steel frame. In addition, the cooperation with the connecting pin can also ensure the stability of the connection between the supporting steel frame, the connecting steel frame, the first reinforcing plate, and the second reinforcing plate.

[0014] In this invention, by providing a connector, the electric push rod can be directly controlled by an external controller during installation, so that the electric push rod can effectively push the connector, causing the connector to be inserted into the connector slot under the action of the thrust. At this time, the insertion structure of the connector and the connector slot will increase the installation strength of the supporting steel frame, connecting steel frame, first reinforcing plate and second reinforcing plate, making them more stable during use.

[0028] The following is combined with Figure 1-5 The embodiments shown illustrate the technical solution of this utility model:

[0029] The system includes a dome frame 1 and a supporting steel frame 2 located below the dome frame 1. A connecting steel frame 3 is located below the supporting steel frame 2. Both the supporting steel frame 2 and the connecting steel frame 3 have internal reinforcement structures. Both the supporting steel frame 2 and the connecting steel frame 3 have positioning holes 4, and guide grooves 5 are provided around the positioning holes 4. The guide grooves 5 are inserted into the positioning holes 4, and a first reinforcing plate 6 is fixedly connected to the top of the guide grooves 5. An L-shaped plate 16 is located below the guide grooves 5. Both the supporting steel frame 2 and the connecting steel frame 3 have connecting holes 9, and both the first reinforcing plate 6 and the second reinforcing plate 15 have connecting grooves 10. Connecting pins 11 are inserted into the connecting holes 9 and the connecting grooves 10, and threaded sleeves 12 are provided at the top and bottom of the connecting pins 11.

[0030] Before use, the positioning holes 4 and connecting holes 9 on the supporting steel frame 2 and connecting steel frame 3 can be aligned directly. Then, the first reinforcing plate 6 can be pushed, causing the positioning pin 7 connected to the first reinforcing plate 6 to insert into the positioning hole 4 on the supporting steel frame 2 and connecting steel frame 3. Simultaneously, the second reinforcing plate 15 is placed on the other side of the positioning pin 7. At this point, the positioning pin 7, the first reinforcing plate 6, and the second reinforcing plate 15 will effectively form an I-shaped structure, thereby fixing the supporting steel frame 2 and connecting steel frame 3 inside the I-shaped structure. This ensures the relative stability between the supporting steel frame 2 and connecting steel frame 3, preventing possible displacement during use. Simultaneously, the first reinforcing plate 6 and the second reinforcing plate 15 will also contact the supporting steel frame 2 and connecting steel frame 3, thereby making the outer... When the load is applied, it can be applied to the first reinforcing plate 6 and the second reinforcing plate 15, allowing the first reinforcing plate 6 and the second reinforcing plate 15 to evenly distribute the load to the supporting steel frame 2 and the connecting steel frame 3, thereby reducing the occurrence of uneven load on the supporting steel frame 2 and the connecting steel frame 3. After the supporting steel frame 2 and the connecting steel frame 3 are fixed, the connecting pin 11 can be inserted into the connecting hole 9 and the connecting groove 10, and the threaded sleeve 12 can be rotated, so that the threaded sleeve 12 is screwed into the connecting pin 11 under the action of the thread structure, thereby making the fixation between the supporting steel frame 2, the connecting steel frame 3, the first reinforcing plate 6 and the second reinforcing plate 15 tighter, thereby improving the stability of the supporting steel frame 2, the connecting steel frame 3, the first reinforcing plate 6 and the second reinforcing plate 15.

[0031] Both the guide groove 5 and the guide plate 8 have trapezoidal cross sections, and the guide groove 5 and the guide plate 8 are compatible. The guide plate 8 can be slidably connected inside the guide groove 5, and both the guide groove 5 and the guide plate 8 have rounded corners.

[0032] When the first reinforcing plate 6 is pushed so that the positioning pin 7 is inserted into the positioning hole 4, the guide groove 5 on the positioning hole 4 will slide effectively along the guide plate 8. At this time, the sliding structure between the guide groove 5 and the guide plate 8 can effectively guide the installation of the positioning pin 7 and the supporting steel frame 2 quickly, thereby improving the overall installation stability and making it more stable during use, avoiding the possibility of displacement or tilting.

[0033] Both the supporting steel frame 2 and the connecting steel frame 3 are provided with recessed grooves, and the recessed grooves and the connecting holes 9 are located on the same central axis. The recessed grooves are provided with internal threaded sleeves 14, and the thread structure on the internal threaded sleeves 14 is compatible with the connecting pins 11.

[0034] The recessed groove effectively provides space for the installation of the inner threaded sleeve 14, making the inner threaded sleeve 14 more stable during installation and use. At the same time, the presence of the inner threaded sleeve 14 effectively avoids the direct opening of the threaded structure inside the connecting hole 9, thereby reducing the impact of stress concentration. Furthermore, when the threaded structure wears out after long-term disassembly, the inner threaded sleeve 14 can be directly replaced, thus simplifying the overall maintenance operation.

[0035] Both sides of the first reinforcing plate 6 and the second reinforcing plate 15 are respectively provided with L-shaped plates 16 and insertion slots 19. The side wall of the L-shaped plate 16 is provided with several electric push rods 17, and the free ends of the several electric push rods 17 are fixedly connected to the same insertion piece 18. The insertion piece 18 is adapted to the insertion slot 19.

[0036] During installation, the electric push rod 17 can be directly controlled by an external controller, so that the electric push rod 17 can effectively push the plug 18, so that the plug 18 is inserted into the plug groove 19 under the action of the thrust. At this time, the plug structure of the plug 18 and the plug groove 19 will increase the installation strength of the supporting steel frame 2, the connecting steel frame 3, the first reinforcing plate 6 and the second reinforcing plate 15, making them more stable during use.

[0037] The side wall of the L-shaped plate 16 is provided with a bending groove 20, and the electric push rod 17 is located inside the bending groove 20.

[0038] The bending groove 20 effectively provides space for the installation of the electric actuator 17, ensuring that the electric actuator 17 has sufficient space when selecting a model, thereby increasing the convenience of later maintenance of the electric actuator 17.

[0039] The bottom of the positioning pin 7 has an installation cavity, and the installation pin 21 is slidably inserted into the cavity. The bottom of the installation pin 21 is fixedly connected to the top of the L-shaped plate 16.

[0040] When the first reinforcing plate 6 is pushed so that the positioning pin 7 is inserted into the positioning hole 4, the second reinforcing plate 15 can also be pushed so that the mounting pin 21 on the second reinforcing plate 15 is inserted into the positioning hole 4. At this time, the insertion structure of the positioning hole 4 and the mounting pin 21 can also effectively limit the position of the second reinforcing plate 15, thereby ensuring that the installation positions of the supporting steel frame 2, the connecting steel frame 3, the first reinforcing plate 6 and the second reinforcing plate 15 are more accurate.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
