Obviously, the embodiments described are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0046] Currently, there are two main types of floor panels in buildings: precast panels and cast-in-place concrete slabs. Precast panels are prefabricated on the ground and installed on-site. However, precast panels are not standardized and construction drawings must be designed based on the product, which requires customized production. The production cycle of precast panels is relatively long. When using precast panels, the size of the room is also limited by the size of the precast panels, so they can only be used in small rooms with dense walls. In addition, the grouting between the panels of precast panels is not well handled, and there will be a clear waterline under the panel, which affects its use.

[0047] Cast-in-place concrete slabs overcome some of the shortcomings of precast slabs. Because they are cast in one piece, cast-in-place slabs offer superior seismic performance to precast slabs. Common quality defects such as temperature cracks found in precast slabs can also be eliminated with cast-in-place slabs. In traditional cast-in-place slab construction, the bottom formwork of cast-in-place concrete slabs is mostly wooden, requiring a large amount of formwork support equipment underneath, resulting in high construction costs. After the concrete dries, the wooden formwork needs to be removed, which results in significant formwork loss during the removal process, resulting in a low formwork recycling rate. To overcome the shortcomings of wooden formwork in slab construction, cast-in-place prefabricated steel truss floor decks were developed.

[0048] Before introducing the steel truss processing system, we first give a detailed introduction to the steel truss floor deck. Figure 1 The steel truss floor deck comprises a base plate 100 and multiple steel trusses, which are arranged at intervals on the base plate 100. The base plate 100 can be a metal plate, such as a galvanized sheet, steel plate, aluminum plate, or composite plate. For example, if the base plate 100 is a metal plate, multiple steel trusses are welded to the base plate 100 to form a complete steel truss floor deck. Before pouring the floor slab, the multiple steel truss floor decks are first spliced ​​together, and then concrete is poured on top of the steel truss floor deck.

[0049] The steel truss includes a first steel bar 11, a second steel bar 12, a third steel bar 13 and a structural steel bar 14. The structural steel bar 14 connects the first steel bar 11, the second steel bar 12 and the third steel bar 13 arranged in parallel to form a triangular prism-shaped frame structure. Specifically, the second steel bar 12 and the third steel bar 13 are arranged in parallel and are located on the same horizontal plane. The first steel bar 11 is located above the second steel bar 12 and the third steel bar 13. The structural steel bar 14 connects the first steel bar 11 to the second steel bar 12 and the first steel bar 11 to the third steel bar 13, respectively, thereby forming a structurally stable steel truss. Beside the second steel bar 12 and the third steel bar 13, the structural steel bar 14 also forms a wing structure 15, and the end of the wing structure 15 is located below the plane where the second steel bar 12 and the third steel bar 13 are located. The wing structure 15 is not only used to connect the steel truss to the galvanized sheet, but also plays a role in supporting the steel truss to prevent the second steel bar 12 and the third steel bar 13 from directly contacting the galvanized sheet. When the side structure 15 is connected to the galvanized sheet, a gap is provided between the second steel bars 12, the third steel bars 13 and the galvanized sheet. In this way, when pouring concrete, the concrete can overflow into the gap, which can effectively prevent the second steel bars 12 and the third steel bars 13 from being exposed, thereby improving the structural strength of the concrete floor slab.

[0050] Typically, for ease of processing, the structural reinforcement 14 is made of smaller diameter steel bars. Although this allows the first steel bar 11 to be connected to the second steel bar 12 and the third steel bar 13, the structural strength of the steel bar truss is not high. During concrete pouring, the first steel bar 11 is subjected to the force of workers stepping on it or the weight of the equipment, and the entire steel bar truss is easily deformed, which will affect the structural strength of the concrete floor slab.

[0051] In order to increase the structural strength of the entire steel truss, short steel bars with the same diameter as the first steel bars 11 need to be welded at both ends of the steel truss. However, this undoubtedly makes the structure of the steel truss more complicated, the processing is complicated, the processing efficiency is low, and it is not conducive to large-scale production.

[0052] To improve processing efficiency, see Figure 3 In one embodiment of the present application, a steel truss processing system is provided. The steel truss processing system includes: a welding device (not shown), a transmission mechanism 3, a first feeding device 1, and a second feeding device 2. The welding device is an automated electric welder, such as a welding robot. Multiple steel trusses are mounted on the transmission mechanism 3, which is used to sequentially transport the steel trusses to different processing stations. After a steel truss is processed at a processing station, the transmission mechanism can transport the steel truss to the next processing station and finally output the processed steel truss.

[0053] See also Figure 3 and Figure 5The first feeding device 1 is located at the first processing station next to the conveyor mechanism 3 and is used to transfer the first short steel bar 20 to the first welding station. The welding equipment welds the first short steel bar 20 to the end position of the steel truss. The second feeding device 2 is located at the second processing station next to the conveyor mechanism 3. After the steel truss welded with the first short steel bar 20 is transported to the second processing station, the second feeding device 2 transfers the second short steel bar 30 to the second welding station. The welding equipment welds the second short steel bar 30 to the first short steel bar 20 and the steel truss.

[0054] The first and second feeding devices 1 and 2 are located below the conveyor mechanism 3. The rebar trusses to be processed are placed on the conveyor mechanism 3, with the ends of the rebar trusses extending outside the conveyor mechanism 3. The first and second feeding devices 1 and 2 transport the short rebars upward from the bottom. Once they reach the welding position, the short rebars contact the rebar trusses, allowing the welding equipment to directly weld them. The conveyor mechanism 3 can be a simple placement table, on which the rebar trusses are placed. When the rebar trusses need to be moved to the next processing station, they can be moved by a robotic arm or directly by a worker.

[0055] Of course, in order to facilitate the automated processing of the steel truss, the transmission mechanism 3 is a conveyor belt platform. When the steel truss is placed on the conveyor belt platform, the conveyor belt can drive the steel truss to move, thereby moving the steel truss to the next processing station.

[0056] See also Figure 2 In one embodiment provided in the present application, along the cross-sectional direction of the steel bar truss, the second steel bar 12 and the third steel bar 13 are located below the first steel bar 11. The first short steel bar 20 is connected to the second steel bar 12 and the third steel bar 13, respectively, and the second short steel bar 30 is connected to the first steel bar 11 and the first short steel bar 20, respectively. When the first short steel bar 20 and the second short steel bar 30 are welded to the ends of the steel bar truss, the first short steel bar 20 is first welded to the second steel bar 12 and the third steel bar 13, and then the second short steel bar 30 is connected to the first steel bar 11 and the first short steel bar 20.

[0057] Furthermore, in one embodiment, a first feeding device 1 and a second feeding device 2 are respectively provided on both sides of the transmission mechanism 3. The first feeding device 1 and the second feeding device 2 on both sides of the transmission mechanism 3 can respectively deliver the first short steel bars 20 and the second short steel bars 30 to the two ends of the steel bar truss. That is, the first feeding device 1 and the second feeding device 2 on both sides of the transmission mechanism 3 can simultaneously feed the two ends of the steel bar truss, making it convenient for the welding equipment to simultaneously weld the two ends of the steel bar truss.

[0058] join Figures 4 to 7In one embodiment provided in the present application, the steel bar truss processing system further includes a bracket 4, on which a first feeding device 1 and a second feeding device 2 are provided. The first feeding device 1 and the second feeding device 2 include: a hopper 21, a feeding assembly 22, and a power device 23. The hopper 21 has a feed port and a discharge port. A plurality of first short steel bars 20 or a plurality of second short steel bars 30 are placed in the receiving chamber of the hopper 21 through the feed port and can be discharged from the discharge port in sequence. Specifically, the bottom of the receiving chamber of the hopper 21 is inclined, and the short steel bars in the receiving chamber can slide along the inclined bottom to the discharge port under the action of gravity.

[0059] See also Figures 4 to 8 The feeding assembly 22 is provided at the discharge port, and a loading portion 221 is provided at the top of the feeding assembly 22 for carrying the first short steel bar 20 or the second short steel bar 30; the power device 23 is connected to the feeding assembly 22 to drive the feeding assembly 22 to realize the feeding action. When the power device 23 drives the feeding assembly 22 to move to the lowest point of the discharge port, the short steel bars (the first short steel bar 20 or the second short steel bar 30) in the hopper 21 can roll onto the loading portion 221, and then the power device 23 drives the feeding assembly 22 to move upward to the welding position. For different feeding devices, the corresponding welding positions are also different. For example, for the first feeding device 1, the welding position is located below the second steel bar 12 and the third steel bar 13, and the first short steel bar 20 located at the welding position will directly contact the second steel bar 12 and the third steel bar 13. For the second feeding device 2, the welding position is located on one side of the end of the second steel bar 12 and the third steel bar 13.

[0060] Further, see Figure 8 The feeding assembly 22 includes a feeding slide 27 and a slide rail 26. The slide rail 26 is vertically arranged at the discharge port of the hopper 21. The feeding slide 27 is slidably connected to the slide rail 26. A loading portion 221 is located at the top of the feeding slide 27. The feeding slide 27 can slide up and down in the slide rail 26. When the feeding slide 27 is in the low position, a short steel bar in the hopper 21 falls onto the loading portion 221. The power device 23 drives the feeding slide 27 upward to deliver the short steel bar to the high position. When the feeding slide 27 is in the low position, it can be considered that the loading portion 221 on the feeding slide 27 is flush with the lowest point of the discharge port. A short steel bar in the hopper 21 can slide directly onto the loading portion 221. The power device 23 then drives the feeding slide 27 upward to feed the steel bar. When the short steel bar is in the high position, it can be considered that the first short steel bar 20 is in the welding position, or the second short steel bar 30 is in the position to be grasped by the steering device 24.

[0061] Usually, in order to facilitate unloading, the first short steel bar 20 and the second short steel bar 30 are respectively arranged horizontally in the hopper 21. However, when welding the second short steel bar 30, the second short steel bar 30 is welded vertically. Therefore, before welding the second short steel bar 30, the second short steel bar 30 needs to be turned from a horizontal setting state to a vertical setting state to facilitate welding.

[0062] See also Figure 6 and Figure 7 The steel bar truss processing system further includes a steering device 24, which is arranged above the second feeding device 2. The steering device 24 grabs the second short steel bar 30 located at a high position, and the steering device 24 drives the second short steel bar 30 to rotate from a horizontal setting state to a vertical setting state, and then is welded to the first steel bar 11 and the first short steel bar 20 by the welding equipment. Figure 4 The second short steel bar 30 arranged horizontally in the hopper 21 falls onto the loading portion 221 of the feeding slide 27 of the second feeding device 2, and the feeding slide 27 moves upward, thereby conveying the second short steel bar 30 to a position flush with the steering device 24, and then the steering device 24 grabs the second short steel bar 30 again, and then the feeding slide 27 retreats, and the steering device 24 drives the second short steel bar 30 to rotate 90 degrees, and the second short steel bar 30 changes from a horizontal setting state to a vertical setting state.

[0063] To facilitate the steering device 24 in grasping the second short steel bar 30, a gripping claw is provided on the rotating portion of the steering device 24. After the gripping claw grasps the second short steel bar 30, the rotating portion rotates to achieve the rotation of the second short steel bar 30. Similarly, to facilitate the steering device 24 in grasping the second short steel bar 30, a notch 222 is provided on the top of the feeding slide 27 of the second feeding device 2. The steering device 24 can grasp the second short steel bar 30 on the loading portion 221 through the notch 222. When grasping the second short steel bar 30, the gripping claw can extend into the notch 222 to achieve stable grasping of the second short steel bar 30.

[0064] When the steering device 24 is turning the second short bar 30, it is necessary to prevent the second short bar 30 from contacting the end of the steel truss. Therefore, when the steering device 24 is gripping and turning the second short bar 30, it must be done at a position away from the end of the steel truss. After the second short bar 30 is turned, it is then driven closer to the end of the steel truss and welded to the first short bar 20 and the first bar 11.

[0065] To implement the above process, see Figure 6 and Figure 7In one embodiment provided in the present application, the steering device 24 includes a telescopic assembly 25, which is provided on the bracket 4, and the steering device 24 is provided on the telescopic assembly 25. The telescopic assembly 25 can drive the steering device 24 to move toward or away from the steel bar truss. Specifically, before the steering device 24 grabs the second short steel bar 30, the steering device 24 is located behind the feeding slide 27. The feeding slide 27 conveys the second short steel bar 30 to a plane flush with the steering device 24. Then the telescopic assembly 25 drives the steering device 24 to move forward, and the grabbing claw grabs the second short steel bar 30. Then the feeding slide 27 is reset downward, and the telescopic assembly 25 continues to drive the steering device 24 forward until it moves to the welding position. The second short steel bar 30 contacts the first short steel bar 20 and the first steel bar 11 respectively. Finally, the welding equipment can weld the second short steel bar 30 to the first short steel bar 20 and the first steel bar 11.

[0066] In the technical solution provided in the present application, the telescopic assembly 25 includes but is not limited to: a pneumatic telescopic cylinder, a hydraulic cylinder, a linear motor device, a screw device, etc.

[0067] In order to adjust the telescopic gear, the telescopic assembly 25 includes a multi-stage telescopic part, and the steering device 24 is connected to the telescopic part of the last stage. Specifically, the multi-stage telescopic part is stacked, and the steering device 24 is connected to the telescopic part of the top layer. Taking the telescopic assembly 25 as an example of a pneumatic telescopic cylinder, the pneumatic telescopic cylinder includes a two-stage pneumatic cylinder. When the two-stage pneumatic cylinders are not extended, the steering device 24 on the pneumatic telescopic cylinder is located at a position away from the feeding slide 27. When the first-stage pneumatic cylinder 251 is extended, the steering device 24 moves forward a distance. At this time, the steering device 24 can grab the second short steel bar 30; when the second-stage pneumatic cylinder 252 is also extended, the steering device 24 continues to move forward a distance, and the second short steel bar 30 on the steering device 24 is moved to the welding position.

[0068] To sum up, in the technical solution provided in the present application, the first conveying mechanism and the second conveying mechanism can convey the first short steel bar and the second short steel bar to the welding position of the steel bar truss of the transmission mechanism in turn, and the welding equipment can weld the first short steel bar and the second short steel bar to the steel bar truss respectively. The processing process of the steel bar truss is simple and convenient, which is conducive to the large-scale production of the steel bar truss.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
