Description

Technical Field

[0001] This invention relates to the field of concrete curing technology, specifically to a prefabricated building concrete curing and covering device. Background Technology

[0002] Prefabricated concrete buildings refer to concrete structures designed and constructed using precast reinforced concrete components produced in factories and assembled on-site. The buildings are connected by cast-in-place concrete to form an assembled monolithic structure. After the concrete finishing process, a film covering process is usually required. Concrete film covering refers to covering the surface of the concrete after it has been poured to prevent moisture from evaporating rapidly.

[0003] A search revealed that the invention patent with publication number CN110080544A discloses a concrete curing and covering device for building construction. Due to the setting of the pressure film protection device, the pressure roller can be used on uneven road surfaces. When the road surface is uneven, the slider moves up and down inside the cylinder by relying on the elastic force of the telescopic spring, thereby changing the force of the entire pressure roller and improving the self-protection capability of the pressure roller.

[0004] In the above technical solution, when the film is applied to the concrete pavement using a pressing roller, although the elastic force of the telescopic spring can be used to adapt to uneven pavement, this "unevenness" refers to the unevenness of the pavement along its length. However, if the pavement is also uneven in its width or contains residual stones, the pressing roller will not be able to evenly press the film in the axial direction, resulting in uneven and unreliable adhesion between the film and the pavement, and poor film application effect. Summary of the Invention

[0005] The purpose of this invention is to provide a prefabricated building concrete curing and covering device to solve the problems mentioned in the background art, such as the difficulty in evenly adhering the covering film to the road surface and the poor covering effect caused by the film not being firm.

[0006] The present invention can be achieved through the following technical solution: a prefabricated building concrete curing and coating device, comprising a movable fixed base, a support column for supporting coating rollers of different lengths is installed on the top surface of the fixed base, and a U-shaped extension frame is fixedly connected to one side surface of the fixed base. A coating roller for coating concrete is installed at the bottom of the extension frame. The film on the coating roller contacts the coating roller through an opening on the extension frame. A wheel pressure chamber is provided on one side of the coating roller, and a wheel pressure assembly for re-coating the film after coating is installed on the bottom surface of the wheel pressure chamber. The roller pressing assembly includes multiple pressing roller 1 and multiple pressing roller 2; Initially, pressure roller one and pressure roller two are at the same height; During the movement, there are two states: the height of pressure roller one is higher than the height of pressure roller two, and the height of pressure roller one is lower than the height of pressure roller two.

[0007] A further technical improvement of the present invention is that: the wheel pressure assembly further includes a shaft 1 and a shaft 2 rotatably mounted inside the wheel pressure chamber. Multiple cams 1 and cam 2 are mounted on the surfaces of the shaft 1 and the shaft 2. Cams 1 and cam 2 on the same side are arranged adjacent to each other, and the clockwise rotation degree of cam 1 coincides with the position of cam 2. Two meshing gears are sleeved on the outer surfaces of the shaft 1 and the shaft 2. Cams 1 and cam 2 on the shaft 1 and the shaft 2 are not arranged to coincide.

[0008] A further technical improvement of the present invention is that: the first pressure roller and the second pressure roller are respectively rotatably mounted at the bottom of the first mounting rod and the second mounting rod, and the top ends of the first mounting rod and the second mounting rod are each equipped with abutting wheels that abut against the first cam and the second cam. The first mounting rod and the second mounting rod both pass vertically through the cavity of the wheel pressure chamber, and the top outer surfaces of the first mounting rod and the second mounting rod are equipped with stops. The outside of the first mounting rod and the second mounting rod are each fitted with a spring, and the spring is located in the stop and the cavity of the wheel pressure chamber.

[0009] A further technical improvement of the present invention is that: the bottom surface of the opening of the U-shaped extension frame is provided with an inclined cutting groove, and an electric push rod is installed on the bottom surface of the fixed base near the side of the extension frame through a bracket plate. The pushing end of the electric push rod is equipped with a cutting blade that cuts the film and faces the cutting groove.

[0010] A further technical improvement of the present invention is that the coating roller includes a long roller and a short roller, wherein the long roller is located directly above the short roller.

[0011] A further technical improvement of the present invention is that: two support columns are installed on the top edge surface of the fixed base, the inner side of the support columns is inclined, and the inner side of the support columns is provided with a U-shaped groove for mounting the long roller and the short roller.

[0012] A further technical improvement of the present invention is that: a docking seat with a through hole is matched and installed inside the U-shaped groove, and a fixing seat is rotatably installed on the outer surface of the docking seat. One end surface of the fixing seat is provided with a plurality of positioning holes arranged in a ring, and the other end of the fixing seat is fixed to the long roller and the short roller.

[0013] A further technical improvement of the present invention is that: the support column has a sliding cavity communicating with the U-shaped groove inside, a push plate is slidably installed inside the sliding cavity, an adjusting rod is threadedly installed on the outer wall of the support column, the end of the adjusting rod is rotatably connected to the push plate, and a plurality of limiting posts are provided on the surface of the push plate, the plurality of limiting posts passing through the through holes on the docking seat and cooperating with the positioning holes.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The film is pressed again by the roller pressing assembly. Roller 1 and roller 2 alternately rise and fall, pressing back and forth. Roller 1 and roller 2 are in a state of high and low or low and high, so that the film is pressed more tightly to the surface of the concrete construction layer. This presses and adheres the plastic film to the uneven surface of the concrete construction layer, avoids the problem of uneven pressing and adhesion, and improves the film pressing quality of the concrete construction layer. 2. The long and short rollers on the two inclined support columns are used to adapt to the pressing and covering of two different width films, which can meet the covering of concrete construction layers with different construction requirements. The adjusting rod pushes the push plate to slide in the sliding cavity. The push plate drives multiple limit columns to leave the sliding cavity and enter the through hole in the docking seat. The long and short rollers are installed between the two support columns to facilitate the replacement of the long or short rollers. 3. Continue to turn the adjusting rod to push the push plate to the end of the sliding cavity. At this time, the limiting post passes through the through hole and reaches the positioning hole to fix the long roller or short roller, ensuring the stability of the film on the long roller or short roller during cutting. The film tension is strong. The electric push rod pushes the cutting blade toward the cutting groove to cut the coated plastic film, resulting in better cutting quality. Attached Figure Description

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0020] Please see Figures 1-8 As shown, this invention provides a prefabricated building concrete curing and coating device, including a movable fixed base 1. A support column 2 for supporting coating rollers of different lengths is installed on the top surface of the fixed base 1. A U-shaped extension frame 5 is fixed to one side surface of the fixed base 1. A pressing roller 6 for coating the concrete is installed at the bottom of the extension frame 5. The film on the coating roller contacts the pressing roller 6 through an opening on the extension frame 5. A wheel pressing chamber 20 is provided on one side of the pressing roller 6. A wheel pressing assembly for re-pressing the coated film is installed on the bottom surface of the wheel pressing chamber 20. The wheel pressing assembly includes multiple pressing rollers 21 and multiple pressing rollers 22. Initially, Pressure roller 1 21 and pressure roller 22 are at the same height. During movement, there are two states: the height of pressure roller 1 21 is higher than the height of pressure roller 22, and the height of pressure roller 1 21 is lower than the height of pressure roller 22. The plastic film passes through the opening on the extension frame 5 and is covered by the covering roller 6 on the already constructed and solidified concrete construction layer. After being covered by the covering roller 6, the film is covered again by the roller pressing assembly. Through the reciprocating covering of pressure roller 1 21 and pressure roller 22, the plastic film is pressed and adhered to the uneven surface of the concrete construction layer, avoiding the problem of uneven covering and improving the covering quality of the concrete construction layer.

[0021] Please see Figure 1 , Figures 5-8As shown, the wheel pressing assembly also includes a first shaft 31 and a second shaft 32 rotatably mounted inside the wheel pressing chamber 20. Multiple cams 1 23 and cam 25 are mounted on the surfaces of both shafts 31 and 32. Cams 1 23 and cam 25 on the same side are adjacent to each other, and cam 1 23 rotates 90 degrees clockwise to coincide with the position of cam 25. Two meshing gears 26 are sleeved on the outer surfaces of both shafts 31 and 32. Cams 1 23 and cam 25 on shafts 31 and 32 are not aligned, thus pressing... During operation, the meshing transmission of gear 26 causes shaft 31 and shaft 32 to move in different directions (i.e., the rotational movements of shaft 31 and shaft 32 are different). Cam 23 and cam 25 on shaft 31 and shaft 32 move together. Since cam 23 rotates 90 degrees clockwise and coincides with the position of cam 25, the rotation of cam 23 and cam 25 facilitates the alternating lifting and lowering of pressure roller 21 and pressure roller 22, making the film adhere more closely to the concrete construction layer.

[0022] Please see Figure 6 and Figure 7 As shown, pressure roller 1 21 and pressure roller 22 are rotatably mounted on the bottom of mounting rod 1 24 and mounting rod 2 30, respectively. The tops of mounting rod 1 24 and mounting rod 2 30 are each equipped with abutting rollers 27 that abut against cam 1 23 and cam 2 25. Mounting rod 1 24 and mounting rod 2 30 both vertically pass through the cavity of the wheel pressure chamber 20. Stop blocks 28 are mounted on the top outer surfaces of mounting rod 1 24 and mounting rod 2 30. Springs 29 are sleeved on the outside of mounting rod 1 24 and mounting rod 2 30, and the springs 29 are located within the stop blocks 28 and the cavity of the wheel pressure chamber 20. Cam 1 23 and cam 2 25 rotate simultaneously, as... Figure 6 As shown, pressure roller 21 and pressure roller 22 are in a flush position, when cam 23 (according to) Figure 6 As shown, when the cam rotates 90 degrees counterclockwise, the second cam 25 rotates 90 degrees clockwise. During the rotation of the first cam 23, it contacts the abutment wheel 27. The abutment wheel 27 presses down on the first mounting rod 24, which drives the first pressure wheel 21 downward. The spring 29 in the cavity of the wheel pressure chamber 20 is squeezed by the stop block 28, while the second pressure wheel 22 connected to the second mounting rod 20 does not move downward. The first pressure wheel 21 and the second pressure wheel 22 are in a high and low state, respectively. The first cam 23 continues to rotate counterclockwise. At this time, the second cam 25 rotates to contact the abutment wheel 27 on the second mounting rod 20. At this time, the second pressure wheel 22 at the bottom of the second mounting rod 20 moves downward. The first pressure wheel 21 and the second pressure wheel 22 are in a low and high state, respectively, thereby achieving a tighter coating between the film and the surface of the concrete construction layer.

[0023] Please see Figure 5As shown, the U-shaped extension frame 5 has an inclined cutting groove 15 on the bottom surface of its opening. An electric push rod 16 is installed on the bottom surface of the fixed base 1 near the side of the extension frame 5 via a bracket plate. The pushing end of the electric push rod 16 is equipped with a cutting blade 17 that cuts the film and faces the cutting groove 15. After the film is coated, the electric push rod 16 pushes the cutting blade 17 toward the cutting groove 15 to cut the coated plastic film.

[0024] Please see Figure 1 and Figure 3 As shown, the coating roller includes a long roller 3 and a short roller 4. The long roller 3 is located directly above the short roller 4. By using the long roller 3 and the short roller 4, it can adapt to the pressing and coating of two different width films, and meet the coating of concrete construction layers with different construction requirements.

[0025] Please see Figure 1 and Figure 2 As shown, two support columns 2 are installed on the top edge surface of the fixed base 1. The inner side of the support column 2 is inclined and has a U-shaped groove 7 for mounting the long roller 3 and the short roller 4. The inclined surface is adapted to the mounting of the long roller 3 and the short roller 4.

[0026] Please see Figure 3 and Figure 4 As shown, a mating seat 8 with a through hole is installed inside the U-shaped groove 7. A fixed seat 13 is rotatably installed on the outer surface of the mating seat 8. One end of the fixed seat 13 has multiple positioning holes 14 arranged in a ring, and the other end of the fixed seat 13 is fixed to the long roller 3 and the short roller 4. The support column 2 has a sliding cavity 9 communicating with the U-shaped groove 7 inside. A push plate 10 is slidably installed inside the sliding cavity 9. An adjusting rod 11 is threaded on the outer wall of the support column 2. The end of the adjusting rod 11 is rotatably connected to the push plate 10. Multiple limiting posts 12 are provided on the surface of the push plate 10. The multiple limiting posts 12 pass through the through hole on the mating seat 8 and cooperate with the positioning holes 14. When installing the long roller 3 or the short roller 4, the mating seat 8 is first installed into the U-shaped groove 7. Inside, by turning the adjusting rod 11, the adjusting rod 11 pushes the push plate 10 to slide in the sliding cavity 9. The push plate 10 drives multiple limiting posts 12 to leave the sliding cavity 9 and enter the through hole in the docking seat 8, installing the long roller 3 and the short roller 4 between the two support posts 2, which facilitates the replacement of the long roller 3 or the short roller 4. Since the docking seat 8 is rotatably connected to the fixed seat 13, the long roller 3 and the short roller 4 can rotate. After the film is attached to the surface of the concrete construction layer, the adjusting rod 11 is turned again to push the push plate 10 to slide to the end of the sliding cavity 9. At this time, the limiting posts 12 pass through the through hole and reach the positioning hole 14 to fix the long roller 3 or the short roller 4, ensuring the stability of the film on the long roller 3 or the short roller 4 during cutting and resulting in better cutting quality.

[0027] Please see Figure 5 As shown, an electric push rod 18 is installed on the bottom surface of the extension frame 5. The extended end of the electric push rod 18 is fixedly connected to a mounting block 19 that is rotatably connected to the pressing roller 6. The side of the mounting block 19 is fixed to the wheel pressing chamber 20.

[0028] In use, the present invention re-presses the film after it has been pressed by the roller pressing assembly. The first pressing roller 21 and the second pressing roller 22 alternately rise and fall, pressing back and forth. The first pressing roller 21 and the second pressing roller 22 are in a state of one high and one low or one low and one high, so as to achieve a tighter pressing between the film and the surface of the concrete construction layer. This presses and adheres the plastic film to the uneven surface of the concrete construction layer, avoids the problem of uneven pressing and adhesion, and improves the film pressing quality of the concrete construction layer. The long roller 3 and short roller 4 on the two inclined support columns 2 are used to adapt to the pressing and covering of two different width films, so as to meet the covering of concrete construction layers with different construction requirements. The adjusting rod 11 pushes the push plate 10 to slide in the sliding cavity 9. The push plate 10 drives multiple limiting columns 12 to leave the sliding cavity 9 and enter the through hole in the docking seat 8. The long roller 3 and short roller 4 are installed between the two support columns 2, which facilitates the replacement of the long roller 3 or the short roller 4. Continue turning the adjusting rod 11 to push the push plate 10 to slide to the end of the sliding cavity 9. At this time, the limiting post 12 passes through the through hole and reaches the positioning hole 14 to fix the long roller 3 or short roller 4, ensuring the stability of the film on the long roller 3 or short roller 4 during cutting. The film tension is strong. The electric push rod 16 pushes the cutting blade 17 toward the cutting groove 15 to cut the coated plastic film, resulting in better cutting quality.
