Description

Technical Field

[0001] The invention relates to the field of building boards, and in particular to a hole-making mechanism, a hole-making device and a hole-making method for a floor deck. Background Art

[0002] As an important building material, floor decking is widely used in modern multi-storey buildings, especially in steel structure buildings. It can not only serve as a temporary working platform during the construction phase, but also form a composite floor with high bearing capacity and rigidity with concrete after concrete pouring. Floor decking is usually made of high-strength steel, which is cold-rolled and has corrugated or ribbed surfaces to increase its strength and rigidity. The application of floor decking can effectively reduce the deadweight of the building, improve construction efficiency, and shorten the construction period.

[0003] In order to enhance the bonding force between the floor deck and the poured concrete, some pits are often designed on the surface of the floor deck. The existence of these pits has the following benefits: Enhanced bonding: The pits on the surface of the floor deck can significantly enhance the mechanical bite between the steel plate and the concrete. The pits provide more contact surfaces and mechanical bite, so that the concrete forms a stronger connection with the floor deck after curing, effectively improving the overall shear strength and tensile strength of the floor. Prevent slippage: In the composite floor slab where the floor deck is combined with concrete, relative slippage may occur due to load or temperature changes. By making pits on the floor deck, this relative slippage can be effectively prevented from occurring, ensuring the overall stability and safety of the structure. Improved fire resistance: The close bonding between the floor deck and the concrete helps to improve the fire resistance of the floor. The pits form a stronger bite between the concrete and the steel plate, which can better prevent the deformation and damage of the steel plate in the event of a fire and maintain the structural integrity of the floor.

[0004] However, floor decking is not always a planar structure in practical applications. In order to adapt to different construction requirements and architectural designs, the shape of the floor decking usually changes, and complex structural forms such as right-angle bends may appear. At these bending lines, in order to ensure the bonding effect between the floor decking and the concrete, dimple processing is usually also required. However, the existing dimple forming equipment has certain limitations and cannot effectively make dimples at the bending lines. Specifically, the existing dimple making equipment is mostly used for the processing of flat plates, and they form regular dimples on the plane by stamping or rolling. However, when the floor decking has a right-angle bending structure, due to the complex geometric shape at the bending line, it is difficult for ordinary equipment to perform precise stamping or rolling processing at the bending line, resulting in the inability to form an effective dimple structure in these areas. This not only affects the bonding force between the floor decking and the concrete at the bending line, but may also cause the shear strength and tensile strength of the overall floor structure to decrease, affecting the safety and service life of the building. Summary of the invention

[0005] The object of the present invention is to overcome the deficiencies in the above-mentioned prior art and to provide a pit-making mechanism, a pit-making device and a pit-making method for a floor deck, which can make a precise pit structure at the bending line of the floor deck.

[0008] In a more preferred embodiment, the pit punching mechanism further includes a buffer spring; the buffer spring is connected to the first pit punching plate, and the buffer spring is used to buffer the impact force between the first pit punching plate, the second pit punching plate and the bending line.

[0009] In a more preferred embodiment, the pit-making mechanism further comprises a rotating roller and a base; the rotating roller is connected to the first pit-making plate, the base is connected to the second pit-making plate, and the buffer spring is connected between the rotating roller and the base; wherein the first pit-making plate is perpendicular to the floor deck, and the second pit-making plate is inclined relative to the floor deck;

[0010] One or more first positioning columns extend downward from the end of the rotating roller, one or more second positioning columns extend upward from the end of the base, and one or more buffer springs are connected between the first positioning columns and the second positioning columns.

[0011] In a more preferred embodiment, the hole-making mechanism includes a plurality of hole-making components; the floor deck includes a plurality of bending lines arranged at intervals along the width direction, and the plurality of bending lines pass through the plurality of hole-making components respectively;

[0012] A plurality of the first pit-making discs are connected to the rotating roller, and a plurality of the second pit-making discs are connected to the base; the rotating roller is used to drive the plurality of the first pit-making discs to rotate.

[0013] In a more preferred embodiment, the rotating roller is fixed, and the base can move closer to or farther away from the rotating roller via the buffer spring.

[0014] The present invention also provides a floor decking slab hole punching device, comprising two hole punching mechanisms; the two hole punching mechanisms are arranged at intervals along the feeding direction;

[0015] The floor decking plate comprises a convex portion convex along the thickness direction, and the convex portion has two bending lines on both sides along the width direction of the floor decking plate;

[0016] The two bending lines are formed in sequence by the two pit-making mechanisms.

[0017] In a more preferred embodiment, the axial direction of the pitting column of the first pitting plate is inclined relative to the floor decking plate, the first pitting plate corresponds to the outer wall at the bending line, and the second pitting plate corresponds to the inner wall at the bending line.

[0018] In a more preferred embodiment, the inclination angle of the second pitting plate relative to the inner side wall at the bending line is 45 degrees.

[0019] The present invention also provides a method for drilling a hole in a floor deck, using the drilling device;

[0020] The pitting method comprises the following steps: S1: passing a floor decking plate with a raised portion through a conveying mechanism and passing it through two pitting mechanisms in sequence along a feeding direction; S2: the first pitting mechanism forms a pit at the bending line on one side of the raised portion, and the second pitting mechanism forms a pit at the bending line on the other side of the raised portion.

[0021] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0022] Through the synergistic effect of the first pitting plate and the second pitting plate, a plurality of pits can be effectively formed at the bending line of the floor decking, thereby significantly enhancing the bonding force between the floor decking and the concrete. The first pitting plate and the second pitting plate are respectively arranged on the inner side and the outer side of the bending line of the floor decking. A plurality of pitting columns are arranged at intervals along the circumference of the first pitting plate, and a plurality of pitting recesses corresponding thereto are arranged at intervals along the circumference of the second pitting plate, ensuring that the two can accurately align with each position of the bending line during the rotation process, thereby achieving precise processing. When the bending line of the floor decking passes through the passing space between the first pitting plate and the second pitting plate along a feeding direction, the first pitting plate and the second pitting plate rotate towards each other, and with the relative rotation of the two, a plurality of pitting columns and a plurality of pitting recesses are sequentially correspondingly engaged, and the bending line of the floor decking is clamped between the pitting columns and the pitting recesses in this process, and with the rotation and extrusion of the plate, the material at the bending line is stretched and a plurality of pits are formed. This design can accurately process pits at the bends of the floor decking, which not only overcomes the technical difficulty that existing equipment cannot make pits at the bends, but also significantly improves the bonding strength and overall shear strength between the floor decking and concrete.

[0023] The design of the pitting mechanism introduces a buffer spring, which further optimizes the mechanical properties and equipment durability during the pitting process. When the bending line of the floor deck passes through the passage space between the first pitting plate and the second pitting plate, the two pitting plates rotate towards each other and extrude and shape the bending line, and a certain impact force is generated in the process. The setting of the buffer spring can effectively absorb and alleviate these impact forces, and prevent damage to equipment components or deformation of floor deck materials due to excessive force in an instant. The introduction of the buffer spring can significantly reduce the vibration and displacement errors that may occur during the pitting process, and ensure the stability and synchronization of the first pitting plate and the second pitting plate in relative motion. This design reduces the unstable factors in the pitting process, improves the forming accuracy of the pits at the bending line, and makes the pits more uniform and consistent, thereby further improving the bonding force between the floor deck and the concrete. The buffer spring effectively reduces the impact and wear on equipment parts during the pitting process, thereby extending the service life of the equipment. By reducing direct hard-to-hard contact and friction, the buffer spring can reduce the maintenance frequency and maintenance cost of the equipment, and improve the work efficiency and economy of the equipment. During the pit-making process, if there is no buffering effect of the buffer spring, the bending line of the floor deck may be damaged by excessive impact force, such as cracks or local deformation. The setting of the buffer spring can effectively reduce the instantaneous impact during the pit-making process, avoid damage to the floor deck material, and thus maintain the overall structural integrity and functionality of the floor deck.

The feeding direction is the length direction of the floor deck 10, and the direction perpendicular to the feeding direction is the width direction of the floor deck 10. The rotating roller 31 and the base 32 are both arranged along the width direction 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, 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 plate 10, the pitting component includes a first pitting plate 331 and a second pitting plate 334, a passing space is formed between the first pitting plate 331 and the second pitting plate 334, the floor decking plate 10 includes a bending line 101, 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 and forming to prevent damage to the equipment or the floor decking plate 10.

[0034] 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.

[0035] The first denting plate 331 and the second denting plate 334 correspond to the inner and outer sides of the bending line 101 respectively, the first denting plate 331 includes a plurality of denting columns 3311 arranged at intervals along the circumferential direction, and the second denting plate 334 includes a plurality of denting recesses 3341 arranged at intervals along the circumferential direction. When the bending line 101 passes through the passing space along the feeding direction, the first denting plate 331 and the second denting plate 334 rotate towards each other, and the plurality of denting columns 3311 and the plurality of denting recesses 3341 are sequentially engaged with each other to stretch the plurality of dents at the bending line 101 between the plurality of denting columns 3311 and the plurality of denting recesses 3341.

[0036] In this embodiment, the first grooving plate 331 includes a first plate body and a plurality of grooving columns 3311. The first plate body is fixedly connected to the rotating roller 31. Referring to the figure, the first plate body is arranged perpendicular to the floor deck 10. The first 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 the diameter of the second side plate body 3314. An annular step 3315 is formed between the first side plate body 3313 and the second side plate body 3314. The plurality of grooving columns 3311 are arranged on the annular step 3315. The two ends of the grooving columns 3311 are respectively connected to the first side plate body 3313 and the second side plate body 3314. The plurality of grooving columns 3311 are respectively at a certain angle relative to the axis of the first plate body. The first side plate body 3313 and the second side plate body 3314 can also play a role in pressing the floor deck 10.

[0037] In this embodiment, the second punching plate 334 is connected to the base 32 through 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 meet at a punching location 336, where the punching column 3311 and the punching recess 3341 form a gear-like meshing structure. In this embodiment, the punching recess 3341 corresponds to the inner side of the bending line 101, and the punching column 3311 corresponds to the outer side of the bending line 101. When the bending line 101 passes through the punching location 336, the punching column 3311 stretches the bending line 101 into the punching recess 3341, and a pit is formed at this time.

[0038] In this embodiment, the bearing member at the end of the rotating roller 31 has one or more first positioning columns 311 extending downward, 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.

[0039] In this embodiment, the two caving mechanisms 3 are arranged at intervals along the feeding direction; the floor decking plate 10 includes a raised portion 102 raised 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 plate 10; the two bending lines 101 are formed by the two caving mechanisms 3 in sequence. The axial direction of the caving column 3311 of the first caving plate 331 is inclined relative to the floor decking plate 10, the first caving plate 331 corresponds to the outer side wall of the bending line 101, and the second caving plate 334 corresponds to the inner side wall of the bending line 101. The inclination angle of the second caving plate 334 relative to the inner side wall of the bending line 101 is 45 degrees. In this embodiment, the inclination angles of the second caving plates 334 of the two caving mechanisms 3 are opposite.

[0040] Since the two pitting mechanisms 3 are arranged at intervals along the feeding direction and the second pitting plates 334 of the two pitting mechanisms 3 have opposite inclination angles, the entire pitting device is more compact in the width direction. The two sides of the raised part 102 are formed in sequence, and a narrower raised part 102 can be formed.

[0041] The raised portion 102 has two bending lines 101 on both sides along the width direction of the floor decking 10. By using two punching mechanisms 3 to process the two bending 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 holes at the bending 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 can be adjusted, so it can be suitable for raised portions 102 of different widths, thereby improving the application range and practicality of the equipment.

[0042] Since the second denting plate 334 is inclined at an angle of 45 degrees relative to the inner side wall of the bending line 101, and the second denting plates 334 of the two denting mechanisms 3 are inclined at opposite angles, this design effectively reduces the material rebound and impact force that may be generated during the denting process. By setting a reasonable inclination angle, the stress during the denting process can be better dispersed, the wear and impact on the equipment can be reduced, and the service life of the equipment can be effectively extended. In addition, the force required during the equipment processing is smaller, which reduces the processing difficulty and energy consumption, and further improves the production efficiency.

[0043] In this embodiment, the two pit punching mechanisms 3 are further connected via a synchronous rotation mechanism 4, so that the first pit punching disc 331 rotates synchronously. In this embodiment, the synchronous rotation mechanism 4 is a belt connected between the two rotating rollers 31.

[0044] The present invention also provides a method for punching holes in a floor decking plate, using a floor decking plate punching device; the punching method comprises the following steps: S1: passing a floor decking plate 10 with a raised portion through a conveying mechanism 2 and sequentially passing through two punching mechanisms 3 along a feeding direction; S2: the first punching mechanism 3 forms a pit at a bending line 101 on one side of the raised portion, and the second punching mechanism 3 forms a pit at a bending line 101 on the other side of the raised portion.

[0045] The above is only a preferred specific implementation 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.
