Description

Technical Field

[0001] This invention relates to the field of precast steel floor slab technology, and in particular to a processing equipment for precast steel floor slabs. Background Technology

[0002] Common building floor systems include reinforced concrete floor systems, core tube-steel frame structure floor systems, and prefabricated floor systems. However, all of these floor systems are limited by the construction method of pouring concrete on-site for the floor slabs.

[0003] However, this traditional approach significantly impacts construction, especially in multi-story frame factory buildings. It requires calculating and setting secondary beams, erecting formwork, and pouring concrete to form the floor slab system, resulting in a massive workload and low construction efficiency. Furthermore, traditional concrete floor slabs require at least five construction steps: formwork erection, rebar tying, concrete pouring, curing and formwork removal, and quality inspection. This demands high skill levels from construction workers. More importantly, traditional building floor slabs are cast in-situ and cannot be removed once poured. If subsequent usage requirements change, the slabs may not meet the necessary conditions.

[0004] Therefore, this application proposes a precast pure steel floor slab and its processing equipment. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of this invention are as follows: 1. This invention assembles and combines floor slabs and secondary beams for the entire floor system, eliminating the traditional concrete-poured floor system and replacing it with lightweight and aesthetically pleasing pure steel prefabricated floor slabs. Compared with traditional floor systems, this floor system is lighter, requires less on-site construction work, has a shorter construction cycle, higher installation efficiency, and reduces construction costs, laying the groundwork for the realization of all-steel prefabricated buildings.

[0015] 2. This invention integrates the secondary beams of the traditional concrete floor system into the floor slab and completes the installation in advance in the factory. This not only ensures the installation quality but also significantly increases the actual usable clearance on the construction site, greatly improving the cost-effectiveness while meeting the functional requirements.

[0016] 3. In this invention, the upper and lower steel plates of the precast pure steel floor slab are welded with connecting inserts and connecting sleeves respectively. The upper connecting insert has a built-in spring buckle, and the lower connecting sleeve has a pre-reserved connecting groove on its side wall surface. The floor slab is assembled by using steel cylinder fastening.

[0017] 4. Compared to traditional concrete floor slabs, the floor slab of this invention avoids problems such as cracking of the bottom concrete. For projects with large floor loads, the height of the cylinder can be increased in conjunction with the height of the secondary beams to improve the bending and shear resistance of the floor slab, effectively reducing the thickness of the upper and lower steel plates, resulting in good economic benefits. 5. This pure steel precast floor slab processing equipment integrates the punching and cutting functions of steel pipes into one unit, eliminating the need for multiple separate machines for cutting and punching. The grooving and cutting operations required for making connecting sleeves and connectors from steel pipes can be completed on a single machine, reducing equipment space requirements and inter-process transfer time, significantly improving overall production efficiency.

[0018] 6. Through the cooperation of the first incomplete gear, the first bevel gear, the lead screw, and the moving plate, the steel pipe is intermittently conveyed at equal distances, with the conveying distance precisely equal to the length of the connecting sleeve and the connecting plug. This precise conveying method ensures dimensional consistency at each processing part, improves product quality stability, and provides a reliable guarantee for the subsequent assembly of pure steel precast floor slabs.

[0019] 7. During the punching process, the solid steel column is inserted into the steel pipe and slides against the inner wall, providing effective internal support for the steel pipe. At the same time, the punching groove on the solid steel column is opposite to the stamping plate. When the steel pipe is punched with the stamping plate, the deformation of the steel pipe due to the punching force can be avoided, which greatly improves the yield, reduces the generation of scrap and defective products, and lowers production costs.

[0020] 8. Ingenious Transmission Design for Stability and Reliability: The transmission mechanism is ingeniously designed, achieving orderly linkage between components through the interaction of multiple incomplete gears, transmission pulleys, and transmission belts. This transmission method not only accurately controls the timing and sequence of each action but also ensures a stable and reliable transmission process, reducing the probability of equipment failure and guaranteeing long-term stable operation of the equipment.

[0021] 9. Reasonable cutting limit to ensure accuracy: During the cutting process, the stamping plate is located within the cutting groove to limit the steel pipe, ensuring the stability of the steel pipe during cutting. This design effectively avoids the shaking and displacement of the steel pipe during cutting, thereby ensuring the accuracy and quality of the cutting and making the dimensions of the cut steel pipe meet the design requirements.

[0022] 10. Convenient operation and cleaning, user-friendly design: The cutting position is not directly adjacent to the solid steel column. After cutting, the solid steel column position is switched, allowing workers to easily remove the cut steel pipe and clean up the waste from the outside. This design considers the convenience of actual operation, reduces the labor intensity of operators, improves work efficiency, and reflects a user-friendly design philosophy. In summary, compared with traditional concrete floor slabs, this invention avoids problems such as easy cracking of the bottom concrete. For projects with large floor loads, the height of the cylinder can be increased in conjunction with the height of the secondary beams to improve the bending and shear resistance of the floor slab, effectively reduce the thickness of the upper and lower steel plates, and has good economic benefits.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Reference Figures 1-3 A precast steel floor slab includes a main beam 5, with a secondary beam 4 extending outwardly attached to the end of the main beam 5 by bolts. The bottom of the main beam 5 is provided with a lower steel plate 6 that abuts against it and is connected to the secondary beam 4, and the upper end of the main beam 5 is provided with an upper steel plate 1 that abuts against it and is connected to the secondary beam 4. The edges of the lower steel plate 6 and the upper steel plate 1 are flush with the flanges of the main beam 5. The lower steel plate 6, the upper steel plate 1 and the secondary beam 4 are connected by fillet welds.

[0027] The upper steel plate 1 and the lower steel plate 6 are connected by multiple connecting mechanisms. The connecting mechanism includes a connecting sleeve 3 welded to the upper end of the lower steel plate 6, a connecting groove 9 extending through the connecting sleeve 3, a connecting insert 2 welded to the bottom of the upper steel plate 1, a sliding groove 7 extending through the connecting insert 2, and a spring buckle 8 slidably connected in the sliding groove 7. After the connecting insert 2 is slidably connected to the connecting sleeve 3, the spring buckle 8 slides in the connecting groove 9. The spring buckle 8 includes a spring and an arc-shaped block. The spring is welded to the arc-shaped block of the connecting insert 2, and the arc-shaped block is located in the sliding groove 7.

[0028] The construction method of the floor includes the following steps: (1) After the main steel column is erected, the main beam 5 is installed; (2) The precast steel floor slab cantilever secondary beam 4 is connected to the main beam 5 with high-strength bolts and clamps, wherein the clamps are the plates at both ends of the main beam 5; (3) The upper surfaces of the lower steel plate 6 and the upper steel plate 1 are flush with the upper flange of the main beam, and the gaps are sealed with precast edge trimming parts, and the lower steel plate 6 and the upper steel plate 1 are snap-fit ​​connected.

[0029] Secondary beam 4 is an H-beam, which has an overhanging section extending beyond the floor slab, and the web of the overhanging section has bolt holes; the web of the H-beam is either a honeycomb web or a corrugated web. Reference Figure 4-10 This invention discloses a processing equipment for precast pure steel floor slabs. The processing equipment includes a support 10, a fixed plate 11 fixed on the support 10, a movable plate 14 that can move intermittently on the fixed plate 11, a guide groove 12 fixed on the fixed plate 11, a transmission box 31 fixed in the guide groove 12, a lead screw 13 rotatably connected in the guide groove 12, the lead screw 13 passing through the movable plate 14 and threadedly connected to it, and a meshing first bevel gear 49 and a first incomplete gear 50 in the transmission box 31. The first bevel gear 49 is fixedly connected to the end of the lead screw 13. The rotation of the first incomplete gear 50 will drive the first bevel gear 49 to rotate intermittently, and the intermittent rotation of the first bevel gear 49 will drive the lead screw 13 to rotate intermittently, thereby driving the guided movable plate 14 to move. The movement of the movable plate 14 will drive the three-jaw chuck 15 and the steel pipe to move, which can transport the steel pipe at a distance equal to the length of the connecting insert 2 and the connecting sleeve 3.

[0030] A three-jaw chuck 15 is fixed on the movable plate 14. The three-jaw chuck 15 holds a steel pipe for making a connecting insert 2 or a connecting sleeve 3. A mounting frame 16 is fixed on the bracket 10. A stamping plate 40 that can move up and down is provided on the mounting frame 16. A rotatable drive shaft 30 is passed through the mounting frame 16. A coaxial circular plate 45 is fixed on the drive shaft 30. A connecting rod 46 is eccentrically hinged to the circular plate 45. A connecting block 47 is hinged to the lower end of the connecting rod 46. The stamping plate 40 is fixed to the bottom of the connecting block 47. A guide frame 48 is fixed on the mounting frame 16. The stamping plate 40 passes through the guide frame 48 and is slidably connected to it. The rotation of the circular plate 45 drives the connecting rod 46, the connecting block 47, and the stamping plate 40 to move down. Under the action of the guide frame 48, the stamping plate 40 can be guided to ensure its stable up and down movement.

[0031] The stamping plate 40 can stamp the steel pipe to process the sliding groove 7 and connecting groove 9 of the connecting sleeve 2 and connecting sleeve 3. The bracket 10 is provided with a rotatable mounting block 18. Two solid steel columns 19 are fixed on the mounting block 18. The end of the solid steel column 19 is provided with a receiving groove 37. The solid steel column 19 can be inserted into the steel pipe and has a punching groove 20 through it that is opposite to the stamping plate 40. The solid steel column 19 slides against the inner wall of the steel pipe to support the steel pipe and prevent it from deforming after being punched.

[0032] A fixed box 21 is fixed on the bracket 10. A motor 22 is installed on the fixed box 21. The fixed box 21 contains a meshing second bevel gear 44 and a second incomplete gear 51. The second incomplete gear 51 is fixedly connected to the output end of the motor 22. A short shaft 24 is fixed on the second bevel gear 44. The short shaft 24 passes through the fixed box 21 and is rotatably connected to it. The mounting block 18 is fixed on the short shaft 24. When the motor 22 works, it drives the second incomplete gear 51 to rotate, which in turn drives the second bevel gear 44 to rotate intermittently. Through the short shaft 24, it drives the mounting block 18 to rotate intermittently, which can alternately change the position of the two solid steel columns 19. The angle of each intermittent rotation is 180 degrees.

[0033] A cutting mechanism is installed on the mounting frame 16. The cutting mechanism includes a guide rod 41 fixed on the mounting frame 16. A drive plate 43 is slidably connected to the guide rod 41. A reciprocating screw 42 is rotatably connected to the mounting frame 16. The reciprocating screw 42 passes through the drive plate 43 and is connected to it. A steel pipe cutting saw 23 is installed on the drive plate 43. The mounting frame 16 is provided with a groove 17 to accommodate the steel pipe cutting saw 23, so as to avoid the steel pipe cutting saw 23 interfering with the movement of the steel pipe.

[0034] It also includes a transmission mechanism, which includes a transmission gear 25 fixedly connected to the transmission shaft 30, a third incomplete gear 26 rotatably connected to the mounting bracket 16, the third incomplete gear 26 meshing with the transmission gear 25, a connecting shaft 27 fixed to the reciprocating screw 42, and first transmission wheels 29 fixed to both the connecting shaft 27 and the third incomplete gear 26. The two first transmission wheels 29 are connected by a first transmission belt 28. A first fixed shaft 33 is fixed to the first incomplete gear 50, a second fixed shaft 36 is fixed to the second incomplete gear 51, a second transmission wheel 39 is fixed to the reciprocating screw 42, a third transmission wheel 32 is fixed to the first fixed shaft 33, a fourth transmission wheel 35 is fixed to the second fixed shaft 36, the third transmission wheel 32 and the second transmission wheel 39 are connected by a second transmission belt 38, and the fourth transmission wheel 35 and the third transmission wheel 32 are connected by a third transmission belt 34.

[0035] The working principle of the connecting sleeve 2 and connecting sleeve 3 in the punching and cutting production of steel pipes is as follows: The steel pipe is clamped and positioned by the three-jaw chuck 15; the motor 22 drives the second incomplete gear 51 to rotate, and the second incomplete gear 51 meshes with the second bevel gear 44, causing the second bevel gear 44 to rotate intermittently. The second bevel gear 44 drives the mounting block 18 to rotate intermittently by 180 degrees through the short shaft 24. At this time, one of the solid steel columns 19 is directly opposite the steel pipe; at this time, the second incomplete gear 51 is not meshed with the second bevel gear 44. The second incomplete gear 51 continues to rotate, driving the second fixed shaft 36 to rotate. Under the transmission of the third transmission wheel 32, the third transmission belt 34, and the fourth transmission wheel 35, the first fixed shaft 33 rotates. The rotation of the first fixed shaft 33 drives the first incomplete gear 50 to rotate. The rotation of the first incomplete gear 50 drives the first bevel gear 49 to rotate intermittently. The first bevel gear 49 drives the lead screw 13 to rotate intermittently. The lead screw 13 drives the guided moving plate 14 to move. The moving plate 14 drives the three-jaw chuck 15 and the steel pipe clamped to make the connecting insert 2 or connecting sleeve 3 to move intermittently at equal distances. The conveying distance is the length of the connecting insert 2 and the connecting sleeve 3, realizing the equal-distance conveying of the steel pipe. At this time, the steel pipe slides on the solid steel column 19, preparing for subsequent punching. Then, the first incomplete gear 50 does not mesh with the first bevel gear 49.

[0036] Driven by the third transmission wheel 32, the second transmission belt 38, and the second transmission wheel 39, the reciprocating screw 42 rotates. The rotation of the reciprocating screw 42 causes the limited drive plate 43 to move the steel pipe cutting saw 23. At this time, the steel pipe cutting saw 23 does not contact the steel pipe.

[0037] The reciprocating screw 42 rotates and the connecting shaft 27 rotates. Under the transmission of the first transmission belt 28 and the first transmission wheel 29, the third incomplete gear 26 rotates. The rotation of the third incomplete gear 26 drives the transmission gear 25 to rotate. The rotation of the transmission gear 25 drives the transmission shaft 30 to rotate. The rotation of the transmission shaft 30 drives the connecting rod 46 to move, thereby driving the connecting block 47 and the stamping plate 40 to move down. The stamping plate 40 moves down and contacts the steel pipe. It can punch the steel pipe in conjunction with the punching groove 20. The punching waste falls into the collection groove 37. Then the third incomplete gear 26 does not mesh with the transmission gear 25. At this time, the stamping plate 40 is located in the punching groove 20 and limits the steel pipe.

[0038] Next, the drive plate 43 drives the steel pipe cutting saw 23 to move and cut the steel pipe. Since the steel pipe is limited, the stability during cutting can be ensured and the quality of cutting can be guaranteed.

[0039] After cutting, the third incomplete gear 26 meshes with the transmission gear 25, causing the circular plate 45 to rotate, thereby resetting the stamping plate 40. Next, the second incomplete gear 51 and the second bevel gear 44 switch the position of the solid steel column 19, allowing workers to remove the cut steel pipe from the outside and clean up the waste. Then, the first incomplete gear 50 meshes with the first bevel gear 49 to transport the steel pipe again. In this way, steel pipes can be cut and grooved without the need for multiple machines for cutting and punching, which greatly improves work efficiency.

[0040] It should be noted that the cutting position is not set close to the solid steel column 19. Therefore, when the steel pipe being cut rotates, it will abut against the fixed steel pipe, which can drive the steel pipe being cut to move without affecting the rotation of the solid steel column 19.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
