DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0038] Please refer to Figures 1 to 10 The present application provides a technical solution: a construction device of a double-layer reinforced concrete floor slab, which comprises a vibrating rod 24 for vibrating the poured concrete of the floor slab and two groups of edge moving bases 1 for supporting the vibrating rod 24, and a smoothing structure for processing the poured concrete is arranged between the two groups of edge moving bases 1.

[0039] The smoothing structure comprises spline shafts 3 for rotating the two groups of edge moving bases 1 and freely rotating in the vertical direction, the spline shafts 3 are provided with horizontal sliding seats 4, the horizontal sliding seats 4 are provided with scrapers 11 for smoothing the concrete and reciprocating swing in the horizontal direction, and the edge moving bases 1 are provided with horizontal moving assemblies for adjusting the horizontal positions of the horizontal sliding seats 4.

[0040] The vibrating rod 24 is arranged on the horizontal sliding seat 4, and the horizontal sliding seat 4 is provided with a vibrating assembly for driving the vibrating rod 24 to reciprocatingly insert into the concrete, and the horizontal sliding seat 4 is provided with a mist spraying assembly for spraying water to the troweling area of the concrete.

[0041] As shown in Figure 1 and Figure 2 In the construction of the double-layer reinforced concrete floor, after pouring the upper layer of concrete, the poured concrete needs to be vibrated and troweled after vibration, wherein the poured concrete is troweled by the reciprocatingly swinging trowel 11 on the horizontal sliding seat 4, and the position of the trowel 11 is changed by driving the horizontal sliding seat 4 to change the position in the horizontal direction, thereby changing the troweling position of the trowel 11 and troweling the concrete in the same horizontal direction.

[0042] Meanwhile, in actual use, the two sets of edge moving bases 1 can be provided with tracks for horizontal longitudinal movement, and the horizontal longitudinal position of the trowel 11 is changed by driving the two sets of edge moving bases 1 to move in the horizontal longitudinal direction, so that the trowel 11 can trowel the entire surface of the concrete.

[0043] Among them, the horizontal sliding seat 4 is provided with a vibrating assembly, and the vibrating assembly is arranged on one side of the horizontal trowel 11, after pouring the concrete, the vibrating assembly first vibrates the concrete to ensure the density of the concrete, eliminate the bubbles in the concrete, improve the strength and durability of the concrete, and then the reciprocatingly swinging trowel 11 passes through the position of the vibrated concrete, and then trowels the position, finally, the mist spraying assembly provided on the horizontal sliding seat 4 sprays water mist to the troweled position of the concrete, thereby ensuring the uniform wetting of the concrete surface to prevent dry cracking and shrinkage.

[0044] It should be noted that in the construction of the cast-in-place double-layer reinforced concrete floor, the presence of the edge moving base 1 may cause some dead angles in the troweling process of the trowel 11, but the dead angle position is at the edge of the concrete floor, and in the case of prefabricated double-layer reinforced concrete floor, the presence of the floor formwork may cause the trowel 11 to have a troweling dead angle, therefore, in actual use, since the dead angle position is at the edge of the floor or near the formwork, the dead angle position can be treated by manual troweling subsequently.

[0045] The present application integrates the functions of vibrating, troweling and water curing by setting the troweling structure, can complete the multiple processing procedures of the concrete in one time during the construction process, reduces the conversion and repeated operation of the equipment, improves the construction efficiency, and the scraper 11 and the components supporting the scraper 11 are above the concrete, which reduces the generation of the concrete surface defects when the concrete is scraped, ensures the flatness and uniformity of the concrete surface, and meanwhile, the steel mesh in the floor will not be loaded during the process of scraping the concrete, thereby avoiding the deformation of the steel mesh, and maintaining the structural performance and overall strength of the floor.

[0046] In one preferred embodiment, the spline shaft 3 is sleeved with a worm 5, the worm 5 is in sliding contact with the inner wall of the horizontal sliding seat 4, the worm 5 is engaged with a worm gear 6, and the worm gear 6 is fixedly rotated on the horizontal sliding seat 4, the worm gear 6 is coaxially fixed with a co-site disc 7, the co-site disc 7 is provided below the swing rod 8 which is fixedly rotated on the horizontal sliding seat 4, and the scraper 11 is bolted on the swing rod 8;

[0047] The co-site disc 7 is fixedly connected with a limiting pin 9 on the side facing the swing rod 8, and the swing rod 8 is provided with a swing slot 10 for sliding the limiting pin 9.

[0048] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9 When the spline shaft 3 rotates in the vertical direction, it can drive the worm 5 sleeved thereon to rotate synchronously, wherein the worm 5 is between the horizontal sliding seats 4 and in contact with the inner wall of the horizontal sliding seats 4, so that when the horizontal position of the horizontal sliding seat 4 changes, the horizontal position of the worm 5 can be changed synchronously.

[0049] At the same time, the worm 5 is engaged with the worm gear 6, and the worm gear 6 is coaxially arranged between the co-site disc 7, so that when the worm 5 rotates vertically, the co-site disc 7 can be driven to rotate horizontally, the co-site disc 7 is provided below the swing rod 8 which can swing, the middle position of the swing rod 8 is fixedly rotated on the horizontal sliding seat 4, wherein the co-site disc 7 is fixedly connected with the limiting pin 9, and the limiting pin 9 is slidably connected to the swing rod 8 through the swing slot 10, so that when the co-site disc 7 drives the limiting pin 9 to rotate and changes the horizontal position of the limiting pin 9, the swing rod 8 and the scraper 11 fixedly arranged thereon can be driven to reciprocate horizontally.

[0050] Further, the mist spraying assembly comprises a first tooth column 13 arranged on the horizontal sliding seat 4, and a plurality of positioning seats 14 are bolted on the positioning seat 14 for the radial sliding of the first tooth column 13;

[0051] The positioning rod 8 is fixedly connected with a sector gear 12 meshing with the positioning rod 8 on one side of a first tooth column 13, and the horizontal sliding seat 4 is fixedly connected with a piston cylinder 27, and the first tooth column 13 is fixedly connected with a piston plate 26 on the side of the piston cylinder 27, and the piston plate 26 is in sliding contact with the inner wall of the piston cylinder 27.

[0052] A plurality of groups of atomizing nozzles 28 are fixedly connected to the horizontal sliding seat 4, and the plurality of groups of atomizing nozzles 28 are in gas communication with the piston cylinder 27, and the atomizing nozzles 28 are further fixedly provided with liquid inlet pipelines penetrating through the atomizing nozzles 28.

[0053] As shown in Figure 2 and Figure 6 When the positioning rod 8 reciprocates on the horizontal sliding seat 4, the fixedly arranged sector gear 12 at the end of the positioning rod 8 can be driven to synchronously oscillate, the sector gear 12 meshes with the first tooth column 13, and the first tooth column 13 can be driven to horizontally slide on the positioning seat 14, and at the same time, the first tooth column 13 is fixedly provided with the piston plate 26 at the end, and the piston plate 26 is driven to reciprocate in the piston cylinder 27.

[0054] The piston cylinder 27 is in gas communication with the atomizing nozzles 28 and in gas communication with an external water supply tank through the liquid inlet pipelines, so that when the piston plate 26 reciprocates in the horizontal direction, the water source in the piston cylinder 27 can be reciprocally pumped and drained, so that the water source in the piston cylinder 27 is squeezed to the atomizing nozzles 28, and the water source is sprayed to the concrete surface that has been smoothed through the atomizing nozzles 28.

[0055] It should be noted that the atomizing nozzles 28 and the liquid inlet pipelines are fixedly provided with one-way valves with opposite valve ports, and through the arrangement of a plurality of one-way valves, the flow direction of the water source is limited, so that the water source can only flow into the piston cylinder 27 through the water supply tank and be sprayed from the atomizing nozzles 28 through the piston cylinder 27.

[0056] On the basis of the embodiment of the mist spraying assembly, the horizontal moving assembly comprises a screw rod 2 arranged between the two groups of edge moving bases 1 and freely rotating in the vertical direction, the screw rod 2 is in threaded cooperation with the horizontal sliding seat 4, and the screw rod 2 and the spline shaft 3 are parallelly arranged, and the two ends of the screw rod 2 are respectively fixedly arranged to rotate on one group of edge moving bases 1.

[0057] The edge moving base 1 is provided with an incomplete gear 29 driven by a motor to freely rotate in the vertical direction, the motor is fixed on the edge moving base 1, the spline shaft 3 is coaxially fixed with a second gear 31 meshing with the incomplete gear 29, and the screw rod 2 is coaxially fixed with a first gear 30 meshing with the incomplete gear 29.

[0058] As shown in Figure 1 , Figure 2 and Figure 7As shown, the motor fixed on the side moving base 1 drives the incomplete gear 29 to rotate freely in the vertical direction, and then drives the first gear 30 and the second gear 31 to rotate in the vertical direction in turn, wherein the first gear 30 can change the horizontal position of the horizontal sliding base 4 in the rotating process, and then adjust the leveling position of the concrete by the screed 11.

[0059] At the same time, the rotating process of the second gear 31 can drive the spline shaft 3 to rotate synchronously, and then drive the worm 5 on the spline shaft 3 to rotate through the rotation of the spline shaft 3, so as to drive the screed 11 to reciprocate in the horizontal direction, and drive the tamping assembly and the mist spraying assembly to operate.

[0060] It should be noted that the screw rod 2 and the spline shaft 3 rotate alternately, and then the horizontal position of the horizontal sliding base 4 of the screed 11 is unchanged when the screed 11 levels the concrete, and after the screed 11 levels the concrete at the position, the horizontal position of the horizontal sliding base 4 and the screed 11 can be changed by the rotation of the screw rod 2, so as to level the concrete at different positions, so as to ensure the flatness and smoothness of the concrete surface.

[0061] On the basis of the embodiment of the horizontal moving assembly, the tamping assembly comprises a sliding frame 20 fixed on the horizontal sliding base 4, the sliding frame 20 is provided with a position adjusting cylinder 18 which rotates freely in the horizontal direction, and the sliding frame 20 is provided with an L-shaped vertical sliding base 21 for supporting a vibrating rod 24 and is provided with a longitudinal sliding groove for the vertical sliding of the L-shaped vertical sliding base 21.

[0062] The L-shaped vertical sliding base 21 is fixedly connected with a position adjusting pin 19 on the side facing the position adjusting cylinder 18, and the position adjusting cylinder 18 is provided with a spiral groove 25 for the sliding of the position adjusting pin 19.

[0063] The first gear column 13 is fixedly connected with a connecting rod 15, and the connecting rod 15 is fixedly connected with a second gear column 16 at the end away from the first gear column 13, and the position adjusting cylinder 18 is fixedly provided with an outer gear ring 17 and the outer gear ring 17 is in meshing connection with the second gear column 16.

[0064] The spiral groove 25 comprises an integral inclined groove part 251 and a horizontal groove part 252, and the inclined groove part 251 and the horizontal groove part 252 are connected end to end.

[0065] The L-shaped vertical sliding base 21 is provided with a torsion seat 22 and is provided with a positioning circular groove 23 for the sliding of the torsion seat 22, and the vibrating rod 24 is fixedly connected to the inner circumferential surface of the torsion seat 22.

[0066] As Figure 1 , Figure 2 , Figure 5 , Figure 8 and Figure 10As shown, when the first tooth column 13 reciprocates in the horizontal direction, the second tooth column 16 can be driven to move synchronously in the horizontal direction through the connecting rod 15, wherein the second tooth column 16 is in meshing connection with the outer tooth ring 17 fixedly sleeved on the adjusting cylinder 18, and the adjusting cylinder 18 is further driven to rotate in the horizontal direction through the outer tooth ring 17.

[0067] Meanwhile, the adjusting pin 19 is slidably connected to the adjusting cylinder 18 through the spiral groove 25, when the adjusting cylinder 18 rotates, the L-shaped vertical sliding seat 21 and the adjusting pin 19 thereon are first driven to move downward, and the vibrating rod 24 arranged on the L-shaped vertical sliding seat 21 is further driven to insert into the concrete, when the adjusting cylinder 18 continues to rotate, the adjusting pin 19 corresponds to the horizontal groove part 252 in position, at this time, the horizontal height of the adjusting pin 19, the L-shaped vertical sliding seat 21 and the vibrating rod 24 is unchanged, i.e. continuously inserted into the concrete.

[0068] Meanwhile, when the adjusting cylinder 18 reversely rotates, the adjusting pin 19 corresponds to the inclined groove part 251 in position, and the adjusting pin 19 slides on the inclined groove part 251, thereby driving the L-shaped vertical sliding seat 21 and the vibrating rod 24 to move upward, and the vibrating rod 24 is pulled out of the concrete, i.e. when the vibrating rod 24 moves in the horizontal direction along the horizontal sliding seat 4 subsequently, the vibrating rod 24 can be prevented from being hindered by the steel bar mesh in the floor slab.

[0069] It should be noted that, since the floor slab is provided with double-layer steel bars, in order to prevent the vibrating rod 24 from being hindered by the steel bar mesh during the process of inserting into the concrete, the L-shaped vertical sliding seat 21 is provided with a torsion seat 22, and a positioning circular groove 23 for the torsion seat 22 to slide is formed, and the vibrating rod 24 is fixedly arranged between the positioning circular groove 23, therefore, during the process of inserting into the concrete, if the vibrating rod 24 contacts the steel bar mesh, the torsion seat 22 can swing in the vertical direction by a certain angle to drive the vibrating rod 24 to insert into the concrete obliquely, so as to prevent the vibrating rod 24 from being hindered by the steel bar mesh and difficult to insert into the concrete.

[0070] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made thereto without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
