Description

Technical Field

[0001] This invention relates to the technical field of concrete layer vibration, and more specifically, to an intelligent vibration structure for large-area, closely spaced concrete layers. Background Technology

[0002] A vibratory rod is a commonly used instrument for compacting concrete layers. The vibratory rod is connected to a vibratory hose, which is connected to a motor. The vibratory rod has an eccentric excitation structure, which is driven by the motor to vibrate eccentrically, thereby transmitting the vibration to the surface of the vibratory rod.

[0003] In actual vibration compaction, the vibrator is inserted into the concrete layer, and the motor drives the eccentric excitation structure in the vibrator to start rotating eccentrically, so that the vibrator can vibrate in the concrete layer, expel air bubbles from the concrete layer, and make the concrete layer achieve a dense state.

[0004] In existing technologies, large-area concrete layers often have densely packed areas with high structural reinforcement, such as transfer floors and foundation slabs in building projects. These densely packed areas are crucial to the structural strength of the entire concrete layer and must be guaranteed to ensure the overall strength of the large-area concrete layer.

[0005] Current vibration compaction methods involve directly inserting the vibrator into the concrete layer, making it impossible to test the density of the concrete and monitor the compaction results. Furthermore, the existing vibration structures are less effective in densely packed areas. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent vibration structure for densely packed areas of large-area concrete layers, aiming to solve the problem of insufficient compaction of concrete layers in the prior art.

[0007] This invention is implemented as follows: an intelligent vibration structure for a large-area concrete layer in a densely packed region includes multiple vibrating rods, a sensor placed in the densely packed region to monitor the concrete density of the concrete layer, and a control terminal. The densely packed region has multiple structural steel reinforcement positions. The vibrating rods are longitudinally arranged and inserted into the densely packed region. The lower part of each vibrating rod has a lower section inserted into the densely packed region and an upper section exposed above the densely packed region. The vibrating rods are connected to a motor via a vibrating hose, and the motor drives the vibrating rods to vibrate.

[0008] An elastic net is provided on the close contact area. The elastic net is connected to the upper sections of multiple vibrating rods, connecting the multiple vibrating rods into an elastic whole. During the vibration of the lower sections of the multiple vibrating rods in the close contact area, the elastic net reciprocates elastically expanding and contracting with the vibration of the vibrating rods. The reciprocating elastic expansion and contraction of the elastic net restrains the multiple vibrating rods to reciprocate elastically in sync.

[0009] The sensor communicates with the control terminal and feeds back the monitored concrete density to the control terminal, which then displays the received concrete density as an image.

[0010] Furthermore, the sensor is an ultrasonic head inserted into the close-fitting area, which monitors the concrete density of the close-fitting area using ultrasonic waves.

[0011] Furthermore, the elastic net is laid on the close-fitting area and is arranged to abut against the top of the close-fitting area.

[0012] Furthermore, the elastic mesh has multiple mesh openings, and multiple elastic strips are formed around the outer periphery of the mesh openings. The multiple elastic strips are joined end to end to form the mesh openings. The ends of the multiple adjacent elastic strips converge and join to form a vibration position. The upper section of the vibrator passes through the vibration position and is directly fixedly connected to the vibration position.

[0013] Furthermore, the elastic strip is flat and is laid flat on the top of the dense area; the vibration position is flat and is laid flat on the top of the dense area; the bottom of the vibration position is provided with multiple elastic protrusions, which are embedded downwards in the dense area.

[0014] Furthermore, the outer surface of the bottom of the lower section is spherical, forming a spherical bottom; the center of the spherical bottom is provided with a rotatably arranged movable shaft segment, the upper end of which is movably inserted into the spherical bottom, and the lower end of which extends freely downward; during the vibration of the vibrator in the close contact area, the movable shaft segment rotates synchronously back and forth.

[0015] Furthermore, a lower connector is provided at the center of the elastic net, and an external vibration source is connected to the lower connector; during the vibration of multiple vibrating rods in the close contact area, the external vibration source drives the elastic net to vibrate, and the vibration elasticity of the elastic net restrains the multiple vibrating rods to vibrate synchronously.

[0016] Furthermore, the lower connector has two locking blocks on its outer periphery, and the external vibration source has an upper connector with an upwardly recessed upper connecting groove. The upper connector has locking slots on both sides. The lower connector is embedded in the upper connecting groove, and the locking blocks are placed in the locking slots so that the external vibration source is relatively fixedly connected to the center position of the elastic net.

[0017] Furthermore, the vibrating rod is connected to a plurality of swing bars in the middle, and the plurality of swing bars are arranged at intervals along the circumference of the vibrating rod; the inner end of the swing bar is hinged to the outer circumference of the vibrating rod, and the outer end of the swing bar extends freely outward.

[0018] During the process of inserting the vibrator into the close-fitting area, the swing bar is blocked by the concrete, and the swing bar swings upward and gathers around the outer periphery of the vibrator; during the vibration process of multiple vibrators, multiple swing bars vibrate synchronously with the vibrator and swing downward to a set angle; during the process of multiple vibrators being pulled out of the close-fitting area, multiple swing bars are blocked by the concrete and swing downward until they gather around the outer periphery of the vibrator.

[0019] Furthermore, the outer periphery of the swing bar is provided with a plurality of freely rotatable rotating rings, which are spaced apart along the length of the swing bar; the outer periphery of the swing bar is provided with a recessed annular groove, which surrounds the outer periphery of the swing bar, and the rotating rings are movably placed in the annular groove; during the vibration of the vibrating rod in the close contact area, the plurality of rotating rings rotate freely accordingly.

[0020] Compared with existing technologies ， The intelligent vibration structure for large-area concrete layer dense areas provided by this invention uses sensors to monitor the concrete density of the concrete layer in real time during vibration and feeds it back to the control terminal to control the working efficiency of the vibrator. Multiple vibrators are driven by motors to vibrate and expel air bubbles from the concrete layer. The concrete layer is then compacted by the reciprocating elastic expansion and contraction deformation of the elastic net, making the concrete in the dense area even denser, thus solving the problem of insufficient compaction of concrete layer during vibration.

[0028] Reference Figure 1-3 The image shown is a preferred embodiment of the present invention.

[0029] The intelligent vibration structure of the large-area concrete layer close-contact area 50 includes multiple vibrating rods 10, a sensor placed in the close-contact area 50 to monitor the concrete density of the concrete layer, and a control terminal. The close-contact area 50 has multiple structural steel bar positions 51 for arranging structural steel bars. The vibrating rods 10 are arranged longitudinally and inserted into the close-contact area 50. The lower part of the vibrating rod 10 has a lower section inserted into the close-contact area 50 and an upper section exposed above the close-contact area 50. The vibrating rod 10 is connected to a motor through a vibrating hose, and the motor drives the vibrating rod 10 to vibrate.

[0030] An elastic net 20 is provided on the close contact area 50. The elastic net 20 is connected to the upper sections of multiple vibrating rods 10, connecting the multiple vibrating rods 10 into an elastic whole. During the vibration of the lower sections of the multiple vibrating rods 10 in the close contact area 50, the elastic net 20 reciprocates elastically expanding and contracting with the vibration of the vibrating rods 10. The reciprocating elastic expansion and contraction of the elastic net 20 restrains the multiple vibrating rods 10 to reciprocate elastically in sync.

[0031] The sensor communicates with the control terminal and feeds back the monitored concrete density to the control terminal, which then displays the received concrete density as a graphic.

[0032] The intelligent vibration structure of the large-area concrete layer dense area 50 provided above can use sensors to monitor the concrete density of the concrete layer in real time during the vibration process and feed it back to the control terminal so as to control the working efficiency of the vibrator 10. Multiple vibrators 10 are driven by motors to vibrate and expel air bubbles from the concrete layer. The concrete layer is then compacted by the reciprocating elastic expansion and contraction deformation of the elastic net 20, so that the concrete in the dense area is even denser, thus solving the problem of insufficient compaction of the concrete layer during vibration.

[0033] Sensors include, but are not limited to: pressure sensors, ultrasonic monitoring sensors, piezoelectric sensors, and electromagnetic spectrometers.

[0034] In this embodiment, the sensor is an ultrasonic head inserted into the close-fitting area 50. The ultrasonic head monitors the concrete density of the close-fitting area 50 using ultrasonic waves. In this way, the ultrasonic head can monitor the density change of the concrete layer in real time during vibration and feed the monitoring signal back to the control terminal.

[0035] In this embodiment, the elastic net 20 is laid on the dense area 50 and is arranged to abut against the top of the dense area 50. In this way, after being affected by the vibration of the vibrator 10, the elastic net 20 will compact the concrete layer during the process of reciprocating elastic expansion and contraction deformation, so as to make the concrete in the dense area even denser.

[0036] In this embodiment, the elastic mesh 20 has multiple mesh openings 21, and multiple elastic strips 22 are formed around the outer periphery of the mesh openings 21. The multiple elastic strips 22 are joined end to end to form the mesh openings 21. The ends of adjacent multiple elastic strips 22 converge and join to form a vibration position 30. The upper section of the vibrating rod 10 passes through the vibration position 30 and is directly fixedly connected to the vibration position 30. In this way, when the vibrating rod 10 vibrates, the vibration force can be more comprehensively transmitted to the multiple elastic strips 22, allowing the elastic strips 22 to expand and contract.

[0037] In this embodiment, the elastic strip 22 is flat and is attached to the top of the close contact area 50 in a flat manner; the vibration position 30 is flat and is attached to the top of the close contact area 50 in a flat manner; the bottom of the vibration position 30 is provided with a plurality of elastic protrusions 31, which are embedded downward in the dense area.

[0038] During the process of multiple vibrating rods 10 vibrating concrete, multiple elastic strips 22 horizontally elastically expand and contract in the close contact area 50, the vibrating position 30 horizontally reciprocates in the close contact area 50, and multiple elastic protrusions 31 horizontally sweep in the close contact area 50; the vibrating position 30 uses multiple elastic protrusions 31 to smooth the concrete layer around the vibrating rod 10, increasing the vibration transmission between concrete layers and making it more compact and thick.

[0039] In this embodiment, the outer surface of the bottom of the lower section is spherical, forming a spherical bottom; the center of the spherical bottom is provided with a rotatably arranged movable shaft section 11, the upper end of the movable shaft section 11 is movably inserted into the spherical bottom, and the lower end of the movable shaft section 11 extends freely downward; during the vibration of the vibrating rod 10 in the close contact area 50, the movable shaft section 11 rotates synchronously back and forth.

[0040] The lower section of the vibrating rod 10 can be inserted into the bottom gap of the close contact area 50 by means of the movable shaft section 11, which increases the vibration range and effect of the vibrating rod 10. The movable shaft section 11 can also improve the vibration effect of the vibrating rod 10 on the extraction position when it is extracted.

[0041] In this embodiment, a lower connector 23 is provided at the center of the elastic net 20, and an external vibration source 40 is connected to the lower connector 23. During the vibration of multiple vibrating rods 10 in the close contact area 50, the external vibration source 40 drives the elastic net 20 to vibrate, and the vibration elasticity of the elastic net 20 restrains the multiple vibrating rods 10 to vibrate synchronously. In this way, the elastic net 20 can be fixedly installed with the external vibration source 40 through the lower connector 23, which facilitates the external vibration source 40 to evenly transmit the power source to each elastic strip 22.

[0042] In this embodiment, the lower connector 23 has two locking blocks 24 on its outer periphery, and the external vibration source 40 has an upper connector 41. The upper connector 41 is recessed upwards to form an upper connecting groove, and locking slots are provided on both sides of the upper connector 41. The lower connector 23 is embedded in the upper connecting groove, and the locking blocks 24 are placed in the locking slots, so that the external vibration source 40 and the center position of the elastic net 20 are relatively fixedly connected. In this way, the external vibration source 40 transmits the power source to each elastic strip 22 more evenly, avoiding insufficient vibration pressure during the compaction of the concrete layer by the elastic net 20.

[0043] In this embodiment, a plurality of swing bars 12 are connected to the middle part of the vibrating rod 10, and the plurality of swing bars 12 are arranged at intervals along the circumference of the vibrating rod 10; the inner end of the swing bar 12 is hinged to the outer periphery of the vibrating rod 10, and the outer end of the swing bar 12 extends freely outward.

[0044] During the process of vibrating rod 10 being inserted into the close contact area 50, the swing bar 12 is blocked by the concrete, and the swing bar 12 swings upward and gathers around the outer periphery of the vibrating rod 10; during the vibration process of multiple vibrating rods 10, multiple swing bars 12 vibrate synchronously with the vibrating rods 10 and swing downward to the set angle; during the process of multiple vibrating rods 10 being pulled out of the close contact area 50 upward, multiple swing bars 12 are blocked by the concrete and swing downward until they gather around the outer periphery of the vibrating rod 10.

[0045] The vibrating rod 10 enhances the multi-directional vibration of the vibrating rod 10 during the vibration process through multiple swing bars 12, thereby realizing the vibration range and vibration effect of the vibrating rod 10.

[0046] In this embodiment, a plurality of freely rotatable rotating rings 13 are sleeved on the outer periphery of the swing bar 12, and the rotating rings 13 are spaced apart along the length direction of the swing bar 12; a recessed annular groove 14 is provided on the outer periphery of the swing bar 12, and the annular groove 14 is arranged around the outer periphery of the swing bar 12, and the rotating rings 13 are movably placed in the annular groove 14; during the vibration of the vibrating rod 10 in the close contact area 50, the plurality of rotating rings 13 rotate freely.

[0047] The oscillating bar 12 uses the vibrating rod 10 to transmit the vibration force to the rotating ring 13 during the vibration process, so that multiple rotating rings 13 vibrate in different directions, making the vibration direction of the vibrating rod 10 more comprehensive and the vibration more practical, thus increasing the vibration efficiency and effect on concrete.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
