Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to the installation structure of pre-assembled steel truss members for a roof. Background Technology
[0002] In large-scale construction projects, roof steel trusses play a crucial role, and their installation is a key construction phase in the entire project. Roof steel trusses bear important functions such as supporting the building roof and transferring loads; their installation quality directly affects the structural stability, safety, and service life of the building.
[0003] However, the installation of prefabricated steel truss components for roofs currently adopts the traditional on-site splicing method, which is greatly affected by the complex construction environment. Due to the high construction height, natural factors such as wind force will also affect the positioning of the components. It is difficult for construction workers to accurately place the components in the predetermined position, and even if they are initially in place, it is difficult to ensure their stability and fixation.
[0004] For example, during the on-site splicing process of large-scale construction projects, the complex construction environment makes it difficult to position and fix the members, resulting in difficulty in ensuring installation accuracy, which affects the stability and safety of the overall steel truss structure. The temporary fixing measures for the members are not reliable enough and are prone to displacement, which further affects the installation quality. Utility Model Content
[0005] This utility model discloses a pre-assembled section installation structure for roof steel trusses, aiming to solve the technical problems of inaccurate positioning and insecure fixing of members in traditional on-site splicing methods.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A prefabricated steel truss installation structure for a roof includes a main frame and connecting plates, and further includes: a fixing mechanism: the fixing mechanism includes a first prefabricated section member connected to the connecting plate, the first prefabricated section member being provided with several installation rods, and a second prefabricated section member being connected to the end of the installation rods away from the first prefabricated section member, the second prefabricated section member being provided with several movable connecting rods, and diagonal support rods being connected to the movable connecting rods; and an auxiliary installation mechanism: the auxiliary installation mechanism is provided on the main frame.
[0008] In this solution, the pre-assembled structural members can be quickly and securely fixed with accurate positioning and stable movement through the setting of a fixing mechanism. In actual use, the modular design allows for simple assembly and adjustment during on-site installation, reducing the workload of on-site splicing. The first and second pre-assembled structural members can be quickly connected and fixed through the installation rod, achieving precise positioning of the first and second pre-assembled structural members. Then, by stretching the diagonal support rod, the diagonal support rod is firmly locked to the installation rod, ensuring a tight connection between the members and forming a stable overall structure. This not only makes the connection of the pre-assembled structural members more secure and stable, but also ensures that they will not loosen during the construction process and affect the quality of subsequent construction.
[0009] In a preferred embodiment, the auxiliary installation mechanism includes a lifting frame connected to the main frame, and a lifter is provided on the side of the lifting frame near the connecting plate.
[0010] During the construction of pre-assembled sections of the roof steel truss, due to their excessive height, the pre-assembled sections can be hoisted using lifting frames and lifting devices, while continuing to play a role in the subsequent installation of the roof steel truss.
[0011] In a preferred embodiment, the mounting rod is provided with a positioning pin, and the first pre-installed section rod and the second pre-installed section rod are provided with a plurality of guide holes, the positioning pin being used in conjunction with the guide holes.
[0012] By adopting the design of positioning pins and guide holes, the amount of on-site splicing work is reduced, making the installation process more convenient and efficient, greatly shortening the construction cycle and reducing project costs. At the same time, positioning pins and guide holes can ensure the accurate installation position of the members and effectively avoid problems such as member displacement, thereby ensuring the installation quality of the pre-assembled members of the roof steel truss.
[0013] As described above, a pre-assembled section member installation structure for a roof steel truss includes a main frame and connecting plates, and further includes: a fixing mechanism: the fixing mechanism includes a first pre-assembled section member connected to the connecting plate, the first pre-assembled section member being provided with several installation rods, and a second pre-assembled section member being connected to the end of the installation rods away from the first pre-assembled section member, the second pre-assembled section member being provided with several movable connecting rods, and diagonal support rods being connected to the movable connecting rods; and an auxiliary installation mechanism: the auxiliary installation mechanism is disposed on the main frame. The bottle-blocking rod for the bottle inspection machine provided by this utility model effectively improves the installation accuracy of the pre-assembled section members of the roof steel truss, ensures the stability and safety of the overall steel truss structure, makes the installation process more convenient and efficient, and guarantees installation quality.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] The pre-assembled steel truss installation structure for rooftops disclosed in this utility model is mainly applied to scenarios where the positioning of the members is inaccurate and the fixing is not secure in the traditional on-site splicing method.
[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A prefabricated steel truss installation structure for a roof includes a main frame 1 and a connecting plate 2, and further includes: a fixing mechanism: the fixing mechanism includes a first prefabricated section member 5 connected to the connecting plate 2, a plurality of installation rods 7 provided on the first prefabricated section member 5, a second prefabricated section member 6 connected to the end of the installation rod 7 away from the first prefabricated section member 5, a plurality of movable connecting rods 10 provided on the second prefabricated section member 6, and diagonal support rods 8 connected to the movable connecting rods 10; an auxiliary installation mechanism: the auxiliary installation mechanism is provided on the main frame 1.
[0024] In practical use, the modular design allows for simple assembly and adjustment during on-site installation, reducing the workload of on-site splicing. The first pre-assembled section member 5 and the second pre-assembled section member 6 can be quickly connected and fixed using the installation rod 7, achieving precise positioning of the first pre-assembled section member 5 and the second pre-assembled section member 6. Then, by stretching the diagonal support rod 8, the diagonal support rod 8 is firmly engaged with the installation rod 7, ensuring a tight connection between the members and forming a stable overall structure. This not only makes the connection of the pre-assembled section members more secure and stable, but also ensures that they will not loosen during the construction process and affect the quality of subsequent construction.
[0025] Reference Figure 2 , Figure 4 and Figure 5 In a preferred embodiment, the first pre-assembled section member 5 is provided with a plurality of threaded fixing rods 9.
[0026] Specifically, by setting several threaded fixing rods 9, preliminary fixing can be performed before welding the pre-assembled section members to the main frame 1, ensuring accurate positioning and effectively improving the installation accuracy of the pre-assembled section members of the roof steel truss.
[0027] The diagonal support rod 8 and the movable connecting rod 10 are connected movably.
[0028] Specifically, the bearing connection enables the inclined support rod 8 to rotate stably around the movable connecting rod 10. It is simple to install and easy to use, which not only strengthens the connection stability of the pre-assembled rod section, but also ensures the aesthetics of the pre-assembled rod section.
[0029] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the auxiliary installation mechanism includes a lifting frame 3 connected to the main frame 1, and a lifter 4 is provided on the side of the lifting frame 3 near the connecting plate 2.
[0030] Specifically, during the construction of the pre-assembled sections of the roof steel truss, due to their excessive height, the pre-assembled sections can be hoisted using the lifting frame 3 and the lifting device 4, while continuing to play a role in the subsequent installation of the roof steel truss.
[0031] The installation positions of the lifting device 4 and the lifting frame 3 are the lifting point positions.
[0032] Specifically, by modeling and analyzing the overall force points and designing appropriate lifting point positions, all positions can be evenly stressed, providing stable support for subsequent welding work. At the same time, a stable lifting process can ensure that deviation is avoided and meet the docking requirements.
[0033] The lifting device 4 is connected to a steel strand, which is used to connect and fix the first pre-assembled section rod 5.
[0034] Specifically, by setting multiple lifting points, each lifting point uses a hoist 4 in conjunction with steel strands to achieve multi-point synchronous lifting. This synergistic effect enables the lifting system to distribute the force, improve the overall lifting capacity, and ensure the stability of the components during the lifting process. The hoist 4, in conjunction with the steel strands, lifts the pre-assembled sections of the rods, facilitating subsequent work. The steel strands have extremely high tensile strength and can withstand huge tensile forces. When used in conjunction with the hoist 4, they can achieve the overall lifting of heavy components.
[0035] Reference Figure 4 and Figure 5 In a preferred embodiment, the mounting rod 7 is provided with a positioning pin, and the first pre-installed section rod 5 and the second pre-installed section rod 6 are provided with a plurality of guide holes, and the positioning pin is used in conjunction with the guide holes.
[0036] Specifically, the use of positioning pins and guide holes reduces the amount of on-site splicing work, making the installation process more convenient and efficient, greatly shortening the construction cycle and reducing project costs. At the same time, the positioning pins and guide holes ensure the accurate installation position of the members, effectively avoiding problems such as member displacement, thereby ensuring the installation quality of the pre-assembled members of the roof steel truss.
[0037] Working Principle: During use, the pre-assembled sections of the roof steel truss are installed simultaneously with the main structure. On the ground, the first pre-assembled section 5 and the second pre-assembled section 6 are quickly connected and fixed using the installation rod 7. Simultaneously, the positioning pins on the installation rod 7 engage with the guide holes on the first and second pre-assembled sections 5 and 6 to achieve initial precise positioning, reducing on-site splicing work and improving installation efficiency. Next, the movable connecting rod 10 on the second pre-assembled section 6 is connected to the diagonal support rod 8 via bearings. Stretching the diagonal support rod 8 securely engages it with the installation rod 7, further enhancing connection stability and ensuring the members form a stable overall structure, preventing... To prevent loosening during construction and movement that could affect quality, lifting points were determined by analyzing the overall force points through modeling. The lifting frame 3 and lifting device 4 were then installed on the main frame 1 at the corresponding lifting point positions to ensure uniform force distribution. The pre-assembled section members were then hoisted using the lifting frame 3 and lifting device 4 in conjunction with steel strands to ensure stability during the lifting process, prevent displacement, and meet the docking requirements. Next, the threaded fixing rod 9 on the first pre-assembled section member 5 was initially fixed to the main frame 1 before welding. Subsequently, the pre-assembled sections were butt-welded to transfer the structure's self-weight to the main structure, forming an overall load-bearing structure, further ensuring positioning accuracy and improving installation precision.
[0038] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
