Abstract
Description
Technical Field
[0001] The present invention belongs to the field of concrete composite slabs, and in particular relates to a finishing device for steel tube truss prestressed concrete composite slabs. Background Art
[0002] Precast sandwich panels are building components composed of precast concrete panels, insulation materials, and a steel reinforcement framework. These panels are prefabricated in a factory and then transported to the construction site for installation. The typical production process involves laying the reinforcement framework in a mold, filling it with insulation, and then pouring concrete. Once the concrete solidifies, the sandwich panel is formed.
[0003] For example, the surface finishing device for a steel tube truss prestressed concrete composite slab with publication number CN118809805A, during the concrete pouring process, drives the second hydraulic telescopic rod and the first hydraulic telescopic rod according to the weight of the concrete, and the first hydraulic telescopic rod drives the connecting frame to move upward. The upward movement of the connecting frame automatically adjusts the height of the vibration plate and the position of the roller, thereby facilitating the vibration and defoaming of the concrete surface and finishing of the concrete surface.
[0004] However, when the concrete is thick, the downward pressure of the roller can only expel and compact the bubbles on the surface, but it is difficult to accurately defoam in local areas (such as areas with dense steel bars, corners and side walls of the insulation board). If the needle plate corresponding to the concrete composite board is repeatedly inserted into the concrete for defoaming, the insulation layer may shift or float due to the flow of concrete if it is not fixed, thereby affecting the quality of the sandwich composite board. Summary of the Invention

DETAILED DESCRIPTION
[0039] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.
[0040] Please refer to Figures 1 to 8 , a finishing device for a steel tube truss prestressed concrete composite slab, comprising: a driving cylinder 1, a vibrating assembly 4 and a smoothing assembly 7;
[0041] A fender 3 is provided around the outer side of the driving cylinder 1, and a vibrating assembly 4 is fixed to the outer wall of the fender 3;
[0042] The vibrating assembly 4 includes a support plate 41, a flexible knife 42, a connecting rope 43 and a spring leaf 44. A plurality of support plates 41 arranged in a matrix are fixed to the outside of the fender 3, and a flexible knife 42 is slidably provided on the inside of the support plate 41. A connecting rope 43 is fixed between two adjacent flexible knives 42, and a spring leaf 44 is fixed to the inner end of the support plate 41 close to the flexible knife 42.
[0043] A support frame 2 is fixed to the outer side of the driving cylinder 1 , and a smoothing component 7 is fixed to one end of the support frame 2 away from the driving cylinder 1 .
[0044] When in use, the support frame 2 is slidably set on the upper end of the prefabricated composite board mold, and then the driving cylinder 1 is started, and the mud guard 3 and the vibrating assembly 4 are driven to rotate by the driving cylinder 1. The spring sheet 44 is in the original length state, and the flexible knife 42 is in the extended state. When the flexible knife 42 rotates to the bottom of the driving cylinder 1, the lower end surface of the support plate 41 is flush with the horizontal surface of the concrete. At the same time, the flexible knife 42 is fully inserted into the concrete. Compared with setting a pressing cylinder on the surface of the concrete, it is easier to insert into the deep layer of the concrete, which is conducive to puncturing deep bubbles.
[0045] In order to improve the bending and shearing resistance of the concrete composite slab, a steel frame is usually set inside the mold. If a sandwich composite slab is to be made, insulation material needs to be filled between the steel frames, and concrete is poured outside the steel frame in the mold to make the composite slab. The gap between adjacent flexible knives 42 is smaller than the gap between the steel bars in the steel frame. At this time, during the concrete pouring process, the concrete has poor fluidity around the steel bars or the insulation layer, and bubbles are easily retained. At this time, when the flexible knife 42 moves to the vicinity of the steel frame, the adjacent flexible knives 42 are inserted into both sides of the steel bar on the steel frame, and the upper end of the steel bar contacts the connecting rope 43, and the spring sheet 44 applies a downward force to the flexible knife 42, and the steel bar The rope 43 exerts an upward force, and the steel bar and the spring sheet 44 are not on the same vertical line, causing the connecting rope 43 to bend. The connecting rope 43 produces a controllable bending deformation due to the reaction force of the steel bar and the directional force of the spring sheet 44, which forces the end of the flexible knife 42 to deflect inward, so that the trajectory of the knife head is switched from straight insertion to arc insertion, accurately bypassing the steel bars and penetrating into the narrow gap between the steel bars. In the process of the flexible knife 42 moving upward, after the pressure exerted by the steel bar on the connecting rope 43 disappears, the flexible knife 42 elastically recovers from the bent state. In this process, the concrete under the steel bar is stirred and the fluidity of the concrete is increased, which facilitates the upward floating of stagnant bubbles. When the knife 42 moves to the top of the insulation layer, the flexible knife 42 at the upper end of the insulation layer exerts a vertical upward supporting force on the flexible knife 42, and is in the same line as the downward pressure of the spring sheet 44, thereby causing the flexible knife 42 to retract upward into the support plate 41. At this time, the spring sheet 44 is in a compressed state. At this time, the downward elastic restoring force of the spring sheet 44 exerts a pressing force on the insulation board, thereby forming an anchoring effect on the insulation board. The lower end of the flexible knife 42 adjacent to the flexible knife 42 at the upper edge of the insulation board has no obstacle with high support, so that the adjacent flexible knife 42 will still move downward. At this time, there is a height difference between the flexible knife 42 at the edge of the insulation board and the flexible knife 42 adjacent to it. The flexible knife 42 at the edge of the insulation board applies an oblique upward pulling force to the adjacent flexible knife 42 through the connecting rope 43, so that the bottom end of the adjacent flexible knife 42 moves toward the side wall of the insulation board, and the blade head of the flexible knife 42 peels off the bubbles adsorbed on the side wall of the insulation board in an oblique cutting manner, thereby increasing the filling density between the side wall of the insulation board and the concrete, and at this time the bottom end of the flexible knife 42 at the upper end of the insulation board has been in contact with the insulation board. Due to the large friction between the insulation board and the flexible knife 42, even if the flexible knife 42 at the edge is dragged outward by the pulling force of the connecting rope 43, it will not be significantly deformed, which is beneficial to improve the stability of the movement of the flexible knife 42 adjacent to the edge flexible knife 42.
[0046] Please refer to Figures 1 to 3A plurality of support cylinders 101 are fixed between the driving cylinder 1 and the mudguard 3 to improve the stability between the mudguard 3 and the driving cylinder 1. At the same time, in order to improve the ability of the device to adapt to composite plates of different thicknesses, the support cylinder 101 can be replaced with an electric telescopic rod. By adjusting the length of the electric telescopic rod, the distance between the mudguard 3 and the concrete can be changed to improve the practicality of the device. At the same time, a disc motor 102 is fixed on the inner side of the driving cylinder 1, and the disc motor 102 is used to drive the driving cylinder 1 to rotate. At the same time, the vibration of the disc motor 102 during operation will be transmitted to the vibrating assembly 4 through the mudguard 3, thereby further facilitating the elimination of bubbles in the concrete.
[0047] A cleaning cover 5 is fixed to the inner side of the support frame 2 , and a retracting frame 6 is fixed to the upper end surface of the cleaning cover 5 .
[0048] Please refer to Figure 4 、 Figure 5 and Figure 7 The smoothing assembly 7 includes a smoothing roller 71, a support shaft 72 and a scraper 73. A support shaft 72 that passes through the support frame 2 is provided directly below the cleaning cover 5, and a smoothing roller 71 is fixed to the outside of the support shaft 72. A scraper 73 is fixed to the lower end surface of the cleaning cover 5, and the position of the scraper 73 corresponds to the position of the smoothing roller 71. When in use, when the driving cylinder 1 moves forward along the mold, the outer wall of the smoothing roller 71 contacts the upper end surface of the concrete. When the support frame 2 moves forward as a whole, the friction between the smoothing roller 71 and the concrete is used to drive the smoothing roller 71 to roll on the concrete surface and smooth the concrete. The scraper 73 is located on the side of the smoothing roller 71 close to the vibrating assembly 4, and the output surface of the scraper 73 corresponds to the outer wall of the smoothing roller 71. At the same time, the smoothing assembly 7 and the vibrating assembly 4 are moved forward synchronously through the support frame 2, and the smoothing assembly moves behind the vibrating assembly 4, making full use of the thixotropic recovery characteristics of the concrete after vibration, and completing the surface finishing in the window period when the aggregate has initially settled but has not yet formed a rigid skeleton. This not only eliminates the risk of stratification caused by the time delay of the traditional secondary smoothing process, but also seals the surface micropores by rolling, significantly improving the interface bonding strength between the composite plate and the cast-in-place layer, and cleans the excess concrete adhering to the outside of the smoothing roller 71 through the scraper 73, and the hanging concrete will be crushed again by the smoothing roller 71 and integrated into the concrete below.
[0049] Please refer to Figure 5 A transmission roller 8 and an oscillation assembly 9 are provided on the inner side of the cleaning cover 5, and the transmission roller 8 and the support shaft 72 are connected by a transmission belt 81. When in use, the transmission roller 8 is driven to rotate by the transmission belt 81 when the smoothing roller 71 rotates.
[0050] Please refer to Figure 7 and Figure 8The oscillation component 9 includes a roller frame 91, a roller 92, a rotating seat 93 and a knocking rod 94. A roller 92 is provided on the outside of the transmission roller 8, and the outer wall of the transmission roller 8 is in close contact with the outer wall of the roller 92. The two ends of the roller 92 are rotatably connected to the roller frame 91, and the outer wall of the roller 92 is fixed with a wedge block 921. The upper end of the roller frame 91 is fixed with a rotating seat 93, and the inner side of the rotating seat 93 is rotatably connected to the knocking rod 94.
[0051] Please refer to Figure 7 A spring plate 911 is fixed to the upper end surface of the roller frame 91 , and the position of the spring plate 911 corresponds to the position of the wedge block 921 , and the knocking rod 94 is arranged parallel to the flexible knife 42 .
[0052] When in use, the roller frame 91 is fixed to the inner wall of the cleaning cover 5. When the smoothing roller 71 rotates, it drives the transmission roller 8 to rotate, and the transmission roller 8 is in close contact with the roller 92, thereby driving the roller 92 to rotate clockwise and driving the wedge block 921 to move to the side close to the knocking rod 94 until its spring plate 911 is in close contact. During the rotation process of the wedge block 921, since the two side surfaces of the wedge block 921 are inclined and open outward, the two bottom surfaces are of different lengths, so that when the wedge block 921 is inserted between the two knocking rods 94, it will drive the two knocking rods 94 to rotate along the rotating seat 93, and the two knocking rods 94 will rotate along the rotating seat 93. The bottom of the rod 94 will expand outward, and before the flexible knife 42 enters the cleaning cover 5, the blade head of the flexible knife 42 contacts the retraction frame 6, and the side of the retraction frame 6 close to the flexible knife 42 is tangent to the rotation trajectory of the flexible knife 42, so that the flexible knife 42 slides along the side wall of the retraction frame 6, causing the flexible knife 42 to retract the inner side of the support plate 41 inward and compress the spring sheet 44. When the flexible knife 42 moves to the end of the retraction frame 6 and enters the cleaning cover 5, the pressure of the retraction frame 6 on the flexible knife 42 disappears, and the elastic potential energy stored in the spring sheet 44 is instantly released, causing the flexible knife 42 to quickly move outward. The spring plate 911 is elastically restored, and the elastic restoring force is used to drive the wedge block 921 to rotate in the opposite direction, until the side wall of the wedge block 921 is separated from the knocking rod 94. At this time, the knocking rod 94 rotates along the rotating seat 93 as the center of the circle. When the flexible knife 42 moves between the two knocking rods 94, it is repeatedly knocked by the knocking rod 94 and the initial setting concrete on the outer side of the flexible knife 42 is knocked off to prevent further solidification and affect the deformation ability of the flexible knife 42. 1 drives the wedge block 921 on the roller 92 to press the spring plate 911, thereby storing energy in the oscillation component 9, and utilizes the elastic restoring force on the vibrating component 4 to trigger the oscillation component 9, so that the flexible knife 42 moves to the front of the knocking rod 94 to trigger the oscillation component 9, thereby realizing the self-circulation supply of cleaning energy consumption, without the need for an external power source, and at the same time, multiple flexible knives 42 are connected by a connecting rope 43. When one flexible knife 42 undergoes elastic deformation, the tension of the connecting rope 43 is transmitted to the adjacent flexible knife 42, causing them to undergo elastic deformation together, thereby facilitating the cleaning of multiple flexible knives 42 together.
[0053] Please refer to Figure 2 and Figure 3 A reinforcing rib 421 is fixed to one end of the flexible blade 42 close to the support plate 41, and the reinforcing rib 421 is located at the upper end of the connecting rope 43. The provision of the reinforcing rib 421 increases the rigidity of the upper end of the connecting rope 43, increases the stability of the flexible blade 42 when it retracts inward, and helps to reduce the risk of the flexible blade 42 breaking at the end of the support plate 41.
[0054] A baffle 422 is fixed to one end of the flexible knife 42 away from the support plate 41 to increase the contact area between the flexible knife 42 and the insulation board, which is beneficial to reducing damage to the insulation layer.
[0055] Please refer to Figure 4 、 Figure 5 and Figure 7 An arc-shaped frame 82 is fixed to the outer walls of both ends of the transmission roller 8, and an arc-shaped groove 51 is opened on the side wall of the cleaning cover 5, which penetrates the side wall of the cleaning cover 5, and a support spring 83 is fixed between the arc-shaped groove 51 and the arc-shaped frame 82. The moving path of the transmission roller 8 is the same as the moving path of the arc-shaped groove 51, and the side wall of the arc-shaped groove 51 is parallel to the line connecting the center of the driving cylinder 1 and the transmission roller 8.
[0056] During use, when the spring sheet 44 on the vibrating assembly 4 elastically recovers, the flexible knife 42 is pulled outward. At this time, the flexible knife 42 is parallel to the line connecting the center of the driving cylinder 1 and the transmission roller 8, and drives the support spring 83 to compress inward, and the arc frame 82 slides along the arc groove 51, thereby separating the transmission roller 8 from the drum 92, so that the driving action of the transmission roller 8 on the drum 92 is suspended, so that the drum 92 can be reversed and separated from the knocking rod 94. The arc groove 51 and the arc frame 82 are conducive to improving the stability of the movement of the transmission roller 8, and the elastic reset of the support spring 83 makes it possible for the transmission roller 8 to re-contact the drum 92 after the force exerted by the flexible knife 42 disappears, and the driving action is restored to ensure that the drum 92 continues to rotate to store energy again. When the next set of vibrating assemblies 4 arrives, it will vibrate again. No manual adjustment is required during this period, making it convenient to use.
[0057] The following further describes the surface finishing device for the steel tube truss prestressed concrete composite slab provided by the present invention in conjunction with the accompanying drawings and implementation methods.
[0058] The fender 3 and the vibrating assembly 4 are driven to rotate with the driving cylinder 1 as the center of the circle, and the vibrating assembly 4 and the smoothing assembly 7 are assembled through the support frame 2. When the support frame 2 is pushed, the vibrating assembly 4 and the smoothing assembly 7 can be driven to slide along the same plane. By setting the vibrating assembly 4, the vibrating assembly 4 includes a retractable flexible knife 42, and a connecting rope 43 is set between the flexible knives 42. When the flexible knife 42 is inserted into the concrete, the steel bars in the concrete contact with the connecting rope 43, and the flexible knives 42 at both ends of the connecting rope 43 are driven by the connecting rope 43 to undergo elastic deformation and move to the side close to the bottom of the steel bars, thereby interweaving and defoaming the gaps between the steel bars. At the same time, when there is an insulation layer in the concrete, the flexible knife 42 is placed vertically with the insulation layer, and the upper end of the insulation layer is driven during the downward pressure. The flexible knife 42 on the surface contracts inward, and at the same time, the elastic restoring force of the spring sheet 44 at the upper end of the flexible knife 42 anchors the insulation layer and limits the movement of the insulation layer. The lower end of the flexible knife 42 adjacent to the flexible knife 42 at the upper edge of the insulation board has no obstacle with high support, so that the adjacent flexible knife 42 will still move downward. At this time, there is a height difference between the flexible knife 42 at the edge of the insulation board and the flexible knife 42 adjacent to it. The flexible knife 42 at the edge of the insulation board applies an oblique upward pulling force to the adjacent flexible knife 42 through the connecting rope 43, so that the bottom end of the adjacent flexible knife 42 moves toward the side wall of the insulation board, and the blade head of the flexible knife 42 peels off the bubbles adsorbed on the side wall of the insulation board in an oblique cutting manner, thereby increasing the filling density between the side wall of the insulation board and the concrete.
[0059] A smoothing component 7 and an oscillation component 9 are set at the rear end of the vibration component 4. The smoothing component 7 and the transmission roller 8 are used to store energy for the oscillation component 9. The flexible knife 42 stores energy for the spring sheet 44 during the sliding process along the retraction frame 6. When the flexible knife 42 is inserted into the cleaning cover 5, the spring sheet 44 releases energy, pushes the flexible knife 42 outward, and drives the transmission roller 8 to slide along the arc groove 51, and separates the transmission roller 8 from the roller 92. During the reversal of the roller 92, the wedge block 921 quickly slides out from between the two knocking rods 94. At this time, the knocking rod 94 rotates along the rotating seat 93 as the center of the circle. When the flexible knife 42 moves between the two knocking rods 94, it is repeatedly knocked by the knocking rod 94, and the initially solidified concrete on the outside of the flexible knife 42 is knocked off, and the smoothing roller 71 can smooth the upper end of the concrete when it rolls along the upper end surface of the concrete.
