Description

Technical Field

[0001] This utility model relates to the field of steel structure construction technology, and in particular to an assembly structure for roof steel truss panels. Background Technology

[0002] Steel truss panels are truss structural units made of steel. They are characterized by high structural efficiency, wide applicability, and flexible design. They play an important load-bearing role in industrial and civil buildings, bridges, towers, and other fields. They can be made into different shapes, such as triangles, trapezoids, parallel chords, polygons, etc., according to actual needs, to adapt to a variety of building and engineering scenarios.

[0003] However, traditional roof steel truss panels are usually assembled and welded on the ground. But when it is necessary to flip them over to work on the other side after welding one side, it often relies on a crane and manual labor to complete the flipping. This method is inefficient and risky.

[0004] For example, during the crane's overturning process, the truss may experience weld cracking due to large swing amplitude or accidental collision, posing a threat to both construction safety and quality. Utility Model Content

[0005] This utility model discloses an assembly and combination structure for roof steel truss panels, aiming to solve the technical problem that when using ground assembly and welding process, but after completing the welding of one side, it is necessary to flip it over for the other side operation, which often relies on the cooperation of cranes and manual labor to complete the flipping, which is inefficient and risky.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An assembly structure for a roof steel truss panel includes a steel truss panel body, two bases, and a support frame mounted on the top outer wall of the bases. The steel truss panel body includes an upper chord, a lower chord, vertical members, and two diagonal members. It also includes:

[0008] Flipping mechanism: The flipping mechanism is set on one outer wall of the support frame. On the opposite outer walls of the two support frames, there are assembly frames set by bearings. Two assembly holes are opened on the top outer wall of the assembly frame. A bidirectional threaded rod is set on the inner wall of the assembly hole. Two equally spaced clamping plates are set on the outer wall of the bidirectional threaded rod.

[0009] Convenience mechanism: The convenience mechanism is disposed on the outer wall of the opposite side of the two bases.

[0010] In this case, the bidirectional threaded rod on the assembly frame of the flipping mechanism works with two clamping plates. By utilizing the differential principle of thread rotation, the clamping plates on both sides move towards each other along the axial direction of the assembly hole. Through electric drive, the temporarily fixed steel truss plate body is smoothly flipped, which improves work efficiency and safety and facilitates the full welding process. In practical applications, high friction coefficient rubber pads can be embedded on the inner side of the clamping plates to further fix the steel truss plate body and prevent it from slipping relative to each other during the flipping process.

[0011] In a preferred embodiment, the convenient mechanism includes two electrically operated telescopic rods disposed on the outer walls of opposite sides of the two bases.

[0012] In particular, the convenient mechanism enables flexible adjustment of the base spacing through electric telescopic rods, adapting to the assembly needs of truss segments of different sizes. The telescopic function of the electric telescopic rods simplifies the adjustment process, reduces manual intervention, and improves assembly efficiency. This design is particularly suitable for construction scenarios with multiple specifications of truss segments, enhancing the versatility of the structure.

[0013] As described above, an assembly structure for roof steel truss panels includes a steel truss panel body, two bases, and a support frame mounted on the top outer wall of the bases. The steel truss panel body includes an upper chord, a lower chord, a vertical member, and two diagonal members. The structure also includes: a flipping mechanism: the flipping mechanism is mounted on one outer wall of the support frame. Assembly frames are mounted on opposite outer walls of the two support frames via bearings. Two assembly holes are formed on the top outer wall of each assembly frame. A bidirectional threaded rod is mounted on the inner wall of each assembly hole, and two equally spaced clamping plates are mounted on the outer wall of the bidirectional threaded rod. A convenient mechanism: the convenient mechanism is mounted on opposite outer walls of the two bases. The assembly structure for roof steel truss panels provided by this utility model has the technical effect of improving work efficiency and safety. Attached Figure Description

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0019] The assembly and combination structure for roof steel truss panels disclosed in this utility model is mainly used in scenarios where ground assembly and welding processes are employed. However, when it is necessary to flip the structure after welding one side, it often relies on a crane and manual labor to complete the flipping, which is inefficient and risky.

[0020] Reference Figure 1 , Figure 2 and Figure 3 An assembly structure for roof steel truss panels includes a steel truss panel body, two bases 5, and a support frame 7 mounted on the top outer wall of the bases 5. The steel truss panel body includes an upper chord 1, a lower chord 2, a vertical member 3, and two diagonal members 4. The structure also includes: a flipping mechanism: the flipping mechanism is mounted on one side of the outer wall of the support frame 7. Each of the two support frames 7 has an assembly frame 9 mounted on its opposite outer wall via bearings. The top outer wall of the assembly frame 9 has two assembly holes. The inner wall of each assembly hole has a bidirectional threaded rod 11, and the outer wall of the bidirectional threaded rod 11 has two equally spaced clamping plates 12. A convenient mechanism: the convenient mechanism is mounted on the opposite outer wall of the two bases 5.

[0021] The vertical rod 3 and the two diagonal rods 4 are all set on the outer wall of the opposite side of the upper chord 1 and the lower chord 2, and the two ends of the upper chord 1 and the lower chord 2 are in contact with the clamping plate 12.

[0022] The upper chord 1 and the lower chord 2 are embedded between two clamping plates 12. The clamping plates 12 are pressed together by a bidirectional threaded rod 11 to ensure that the truss plate body is firmly fixed during the flipping process, avoids slippage or displacement, and improves stability.

[0023] In the specific implementation process, the bidirectional threaded rod 11 on the assembly frame 9 in the flipping mechanism cooperates with two clamping plates 12. By using the differential principle of thread rotation, the clamping plates 12 on both sides move towards each other along the axial direction of the assembly hole. Through electric drive, the temporarily fixed steel truss plate body is smoothly flipped, which improves the work efficiency and safety and facilitates the comprehensive welding process. In practical applications, high friction coefficient rubber pads can be embedded on the inner side of the clamping plates 12 to further fix the steel truss plate body and prevent it from slipping relative to each other during the flipping process.

[0024] Reference Figure 1 and Figure 2 In a preferred embodiment, a motor 10 is provided on one outer wall of each of the two support frames 7, and the output shaft of the motor 10 is connected to one outer wall of the assembly frame 9.

[0025] In particular, the motor 10, as a power source, can precisely control the flipping angle and speed, avoiding the instability of manual operation. It is especially suitable for flipping operations of large or heavy truss panels. This design not only improves construction efficiency, but also reduces safety hazards caused by human error.

[0026] Reference Figure 1 and Figure 3 In a preferred embodiment, a knob 13 is provided at one end of the bidirectional threaded rod 11, and one end of the bidirectional threaded rod 11 is mounted on the bottom inner wall of the assembly frame 9 via a bearing.

[0027] Specifically, the operator can rotate the knob 13 to drive the bidirectional threaded rod 11 to rotate, causing the two clamping plates 12 to move in two directions, thereby clamping or loosening the truss pieces and improving the structural adaptability.

[0028] Reference Figure 2 In a preferred embodiment, the convenience mechanism includes two electrically operated telescopic rods 8, which are disposed on the outer walls of opposite sides of the two bases 5.

[0029] In particular, the convenient mechanism enables flexible adjustment of the spacing of the base 5 through the electric telescopic rod 8, which can adapt to the assembly requirements of truss segments of different sizes. The telescopic function of the electric telescopic rod 8 simplifies the adjustment process, reduces manual intervention, and improves assembly efficiency. This design is particularly suitable for construction scenarios with multiple specifications of truss segments, enhancing the versatility of the structure.

[0030] Reference Figure 1 In a preferred embodiment, two casters 6 are provided on the bottom outer wall of the base 5. The casters 6 are installed at the bottom of the base 5, and the operator can push the whole structure to the designated position. The casters 6 have a locking function to ensure the stability during assembly. After the movement is completed, the wheels are locked, and subsequent operations can be carried out.

[0031] Working principle: During use, the operator can adjust the distance between the two bases 5 according to the different specifications of the steel truss body through the electric telescopic rod 8. Then, the two ends of the upper chord 1 and lower chord 2 of the steel truss body to be welded are inserted between the two clamping plates 12. By rotating the knob 13, the clamping plates 12 are pressed by the double-threaded rod 11 to ensure that the truss body is firmly fixed during the flipping process and to avoid slippage or displacement. Then, the motor 10 is started, and the assembly frame 9 and the steel truss body fixed on it are driven to rotate through the output shaft to achieve smooth flipping and facilitate comprehensive welding operations.

[0032] 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.
