Description

Technical Field

[0001] The utility model relates to the field of building boards, in particular to a pit-making mechanism and pit-making equipment for a floor deck. Background Art

[0002] Floor decking, as an important building material, is widely used in modern multi-story buildings, particularly steel structures. It not only serves as a temporary working platform during construction but also, after concrete pouring, forms a composite floor slab with high load-bearing capacity and rigidity. Floor decking is typically made of high-strength steel, cold-rolled and finished with corrugations or ribs to increase its strength and rigidity. The use of floor decking can effectively reduce a building's deadweight, improve construction efficiency, and shorten construction schedules.

[0003] To strengthen the bond between the floor deck and the poured concrete, dimples are often designed into the deck's surface. These dimples offer several benefits: Strengthening Bond: The dimples on the deck significantly enhance the mechanical bond between the steel plate and the concrete. The dimples provide more contact surface and mechanical engagement, strengthening the concrete's bond with the deck after curing, effectively increasing the slab's overall shear and tensile strength. Preventing Slip: In composite slabs where the deck is bonded to concrete, relative slip can occur due to loads or temperature fluctuations. Dipping the deck effectively prevents this relative slip, ensuring the overall stability and safety of the structure. Improving Fire Resistance: The tight bond between the deck and concrete helps improve the slab's fire resistance. The dimples create a stronger bond between the concrete and the steel plate, preventing deformation and damage to the steel plate in the event of a fire and maintaining the slab's structural integrity.

[0004] In existing technology, pitting the surface of floor decking is typically achieved through rolling. As the deck passes between upper and lower rollers, the pitting components form pit-like structures on the surface of the decking. While this method offers high production efficiency and uniform pitting, it has certain drawbacks. Common pitting components on the market are typically integrated with the rollers. This means that if the pitting components wear or become damaged due to long-term use or other reasons, the entire roller must be replaced. This not only increases maintenance and replacement costs, but also increases equipment downtime, impacting production efficiency. Utility Model Content

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] See Figures 1-9 , a floor decking pitting device, the pitting device includes a frame 1, a conveying mechanism 2 and two pitting mechanisms 3. The conveying mechanism 2 and the two pitting mechanisms 3 are arranged on the frame 1, and the frame 1 is placed on the ground.

[0034] The frame 1 includes a bottom frame 11, a side frame 12 and a top frame 13. The side frame 12 is connected between the bottom frame 11 and the top frame 13. The bottom frame 11, the side frame 12 and the top frame 13 form a working space. The conveying mechanism 2 and the pit-digging mechanism 3 are arranged in the working space. The bottom frame 11 is used to be placed on the ground.

[0035] The conveying mechanism 2 is disposed upstream and downstream of the cratering mechanism 3 along a feeding direction. Specifically, the conveying mechanism 2 includes a first conveying roller mechanism 21 and a second conveying roller mechanism 22, which are respectively disposed upstream and downstream of the cratering mechanism 3 along the feeding direction. The first conveying roller mechanism 21 and the second conveying roller mechanism 22 each include an upper conveying roller 23 and a lower conveying roller 24. The floor deck 10 passes between the upper conveying roller 23 and the lower conveying roller 24 and is transported through the cratering mechanism 3 by the upper conveying roller 23 and the lower conveying roller 24.

[0036] The pit-digging mechanism 3 includes a rotating roller 31, a base 32, and multiple pit-digging components. The feed direction is the length of the floor deck 10, and the direction perpendicular to the feed direction is the width of the floor deck 10. The rotating roller 31 and the base 32 are both arranged along the width of the floor deck 10. The two ends of the rotating roller 31 are respectively connected to the two ends of the base 32 through buffer springs 34, and the rotating roller 31 or the base 32 is fixedly connected to the frame 1. The rotating roller 31 and the base 32 can be relative or away from each other through the buffer spring 34. A plurality of the pitting components are arranged on the rotating roller 31 and the base 32 at intervals along the width direction of the floor decking 10, and the pitting component includes a first pitting plate 331 and a second pitting plate 334, and a passing space is formed between the first pitting plate 331 and the second pitting plate 334. The floor decking 10 includes a bending line 101, and the bending line 101 can pass through the passing space to form a pit at the bending line 101. The buffer spring 34 can absorb the impact force during stretching to prevent damage to the equipment or the floor decking 10.

[0037] The floor decking plate 10 includes a plurality of bending lines 101 arranged at intervals along the width direction, and the plurality of bending lines 101 pass through the plurality of grooving components respectively; a plurality of the first grooving plates 331 are connected to the rotating roller 31, and a plurality of the second grooving plates 334 are connected to the base 32; the rotating roller 31 is used to drive the plurality of the first grooving plates 331 to rotate.

[0038] The first grooving plate 331 and the second grooving plate 334 correspond to the inner and outer sides of the bending line 101 respectively, the first grooving plate 331 includes a plurality of grooving columns 3311 arranged at intervals along the circumference, and the second grooving plate 334 includes a plurality of grooving recesses 3341 arranged at intervals along the circumference. When the bending line 101 passes through the passing space along the feeding direction, the first grooving plate 331 and the second grooving plate 334 rotate towards each other, and the plurality of grooving columns 3311 and the plurality of grooving recesses 3341 are sequentially engaged with each other to stretch the bending line 101 located between the plurality of grooving columns 3311 and the plurality of grooving recesses 3341 into a plurality of the grooves.

[0039] In this embodiment, the first grooving plate 331 includes a plate body and a plurality of grooving posts 3311. The plate body is fixedly connected to the rotating roller 31. Referring to the figure, the plate body is positioned perpendicular to the floor deck 10. The plate body includes a first side plate body 3313 and a second side plate body 3314. The diameter of the first side plate body 3313 is larger than that of the second side plate body. An annular step 3315 is formed between the first side plate body 3313 and the second side plate body 3314. The plurality of grooving posts 3311 are positioned on the annular step 3315, with the ends of the grooving posts 3311 respectively connected to the first side plate body 3313 and the second side plate body 3314. The plurality of grooving posts 3311 are each angled relative to the axis of the plate body. The first side plate body 3313 and the second side plate body 3314 can also serve to press down the floor deck 10.

[0040] The disk body also includes a fixed end disk 3316, and the disk body includes a plurality of mounting slots. The extension lines of the plurality of mounting slots along one end of the axis intersect with the axis of the disk body, and the plurality of mounting slots are at a certain angle to the axis of the disk body. The mounting slots include an entrance section 3317a, an exposed section 3317b and a blind hole section 3317c. The entrance section 3317a is located on the end surface of the second side disk body 3314, the exposed section 3317b is located on the annular step 3315, and the blind hole section 3317c is located on the first side disk body 3313. The pitting column 3311 can be installed into the mounting slot from the entrance section 3317a. In the hole, the two ends of the caving column 3311 are respectively located in the entrance section 3317a and the blind hole section 3317c, and the middle part of the caving column 3311 is exposed on the exposed section 3317b. The fixed end plate 3316 is fixedly connected to the end face of the second side plate 3314 to support and fix the caving column 3311; the second caving plate 334 includes a plurality of caving recesses 3341 arranged at intervals along the circumference, the first caving plate 331 and the second caving plate 334 rotate towards each other and intersect at a caving point 336, and the bending line 101 can stretch out a plurality of the caving recesses through the caving point 336 with the bending line 101.

[0041] The end surface of the second side plate 3314 includes a first flat end surface 3314a and an inclined end surface 3314b extending circumferentially along the first flat end surface 3314a. The inlet of the inlet section 3317a is located on the inclined end surface 3314b. The fixed end plate 3316 also includes a matching groove 3316a adapted to the inclined end surface 3314b. The matching groove 3316a and the inclined end surface 3314b form a space, and one end of the cratering column 3311 is located in the space. The matching groove 3316a abuts against the cratering column. The fixed end plate 3316 also includes a second flat end surface 3316b, which abuts against the first flat end surface 3314a.

[0042] The rotating roller 31 passes through the disc body and the fixed end disc 3316, and the rotating roller 31 can drive the disc body and the fixed end disc 3316 to rotate; the pit-making mechanism 3 also includes fixed shaft sleeves located on both sides of the first pit-making disc 331, and the fixed shaft sleeves press against the disc body and the fixed end disc 3316 respectively.

[0043] The first cratering disc 3313 adopts a split design, so that the disc bodies on both sides can be opened and separated, thereby facilitating the replacement of the cratering column. In this way, when the cratering column 3311 needs to be replaced due to wear or damage, it is only necessary to open the fixed end cover 3316 and replace the cratering column 3311 without replacing the entire disc body. This design significantly reduces maintenance costs and downtime, and improves production efficiency. The exposed section 3317b is designed to expose the cratering column 3311 so that the middle part of the cratering column 3311 is exposed to the outside of the disc body. This design can ensure that both ends of the cratering column 3311 are fixed in the disc body, providing additional support and stability, preventing the cratering column 3311 from being displaced or loosened during operation, and improving the stability and uniformity of the cratering effect.

[0044] The cratering column 3311 is connected to the disc body in a detachable manner, providing flexible maintenance and replacement options. The two ends of the cratering column 3311 are respectively located in the entrance section 3317a and the blind hole section 3317c, further increasing the fixity of the cratering column 3311 and its stability during operation. The two ends of the cratering column 3311 are respectively fixed in the entrance section 3317a and the blind hole section 3317c, with the middle part exposed on the exposed section 3317b. At the same time, the fixed end disc 3316 is fixedly connected to the end face of the second side disc body. This design makes the cratering column evenly stressed, reducing the wear or damage of the cratering column 3311 caused by uneven stress. The overall structure is more stable, further extending the service life of the equipment.

[0045] In this embodiment, the second punching plate 334 is connected to the base 32 via a connecting seat 335. Referring to the figure, the second punching plate 334 is arranged obliquely relative to the floor deck 10. A plurality of punching recesses 3341 are formed on the outer periphery of the second punching plate 334. The first punching plate 331 and the second punching plate 334 intersect at the punching location 336. At the punching location 336, the punching columns 3311 and the punching recesses 3341 form a structure similar to gear meshing. In this embodiment, the punching recesses 3341 correspond to the inner side of the bending line 101, and the punching columns 3311 correspond to the outer side of the bending line 101. When the bending line 101 passes through the punching location 336, the punching columns 3311 correspondingly stretch the bending line 101 into the punching recesses 3341, and a pit is formed at this time.

[0046] In this embodiment, the bearing member at the end of the rotating roller 31 has one or more first positioning columns 311 extending downward, and the end of the base 32 has one or more second positioning columns 321 extending upward, and one or more buffer springs 34 are connected between the first positioning columns 311 and the second positioning columns 321.

[0047] In this embodiment, the two cratering mechanisms 3 are spaced apart along the feed direction; the floor decking 10 includes a raised portion 102 that protrudes along the thickness direction, and the raised portion 102 has two bending lines 101 on both sides along the width direction of the floor decking 10; the two bending lines 101 are formed in sequence by the two cratering mechanisms 3. The axial direction of the cratering column 3311 of the first cratering plate 331 is inclined relative to the floor decking 10, and the first cratering plate 331 corresponds to the outer wall of the bending line 101, and the second cratering plate 334 corresponds to the inner wall of the bending line 101. The inclination angle of the second cratering plate 334 relative to the inner wall of the bending line 101 is 45 degrees. In this embodiment, the inclination angles of the second cratering plates 334 of the two cratering mechanisms 3 are opposite.

[0048] Since the two caving mechanisms 3 are spaced apart along the feeding direction and the second caving plates 334 of the two caving mechanisms 3 are inclined at opposite angles, the entire caving device is more compact in the width direction. The two sides of the raised portion 102 are formed sequentially, and a narrower raised portion 102 can be formed.

[0049] The raised portion 102 has two bend lines 101 on either side of the width of the floor decking 10. By using two punching mechanisms 3 to process the two bend lines 101 respectively, it can effectively adapt to floor decking 10 with different shapes and structural characteristics. Whether it is a simple planar structure or a complex multi-bend structure, this design can ensure that the equipment can effectively punch the bend lines 101, thereby improving the application range and practicality of the equipment. The relative positions of the punching components of the two punching mechanisms 3 are adjustable, so that it can be applied to raised portions 102 of different widths, thereby improving the application range and practicality of the equipment.

[0050] Because the second denting plate 334 is tilted at a 45-degree angle relative to the inner sidewall of the bend line 101, and the second denting plates 334 of the two denting mechanisms 3 are tilted at opposite angles, this design effectively reduces material rebound and impact forces that may occur during the denting process. By properly setting the tilt angle, stress during the denting process is better dispersed, reducing wear and impact on the equipment, and effectively extending the equipment's service life. Furthermore, the force required during the processing is reduced, reducing processing difficulty and energy consumption, further improving production efficiency.

[0051] In this embodiment, the two pit punching mechanisms 3 are further connected by a synchronous rotation mechanism 4 to synchronize the rotation of the first pit punching disc 331. In this embodiment, the synchronous rotation mechanism 4 is a belt connected between the two rotating rollers 31.

[0052] The above is only a preferred specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
