Technical Field

[0001] This invention relates to the field of building construction, and in particular to a concrete pouring formwork and pouring method. Background Technology

[0002] Concrete casting formwork is a mold plate used to shape concrete components according to geometric dimensions, primarily for shaping freshly poured concrete. In concrete engineering, traditional concrete casting formwork has a simple structure and a single operation method; it simply involves pouring concrete into the formwork and then waiting for it to cure. However, during the concrete pouring process, air bubbles can easily remain in the concrete. After the concrete has solidified, the presence of these air bubbles can affect its density and strength, leading to cracks or hollow areas, thus impacting the quality of the project. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing a concrete pouring template and pouring method that can eliminate residual air bubbles in concrete through mixing and vibration, thereby improving the compactness, strength and quality of concrete forming and avoiding cracks and hollow areas.

[0004] On one hand, the present invention proposes a concrete pouring formwork, including a base, a formwork, a vibrating mechanism, a position adjustment mechanism, and a lifting mechanism; the upper part of the base is provided with a mold shell with an open top; the formwork includes a cover plate part one and a cover plate part two integrally connected and vertically distributed; the vibrating mechanism is provided on the cover plate part one; the position adjustment mechanism adjusts the formwork to the position where the cover plate part one or the cover plate part two faces the mold shell; the lifting mechanism adjusts the formwork to the position where the cover plate part one is in contact with the top of the mold shell, so as to use the vibrating mechanism to stir and vibrate the concrete in the mold shell, and adjusts the formwork to the position where the cover plate part two is in contact with the top of the mold shell, and waits for the stirred and vibrated concrete to form.

[0005] Preferably, the vibrating mechanism includes a housing mounted on a cover plate, a rotating drum rotatably mounted on the housing, a drive assembly for driving the rotating drum to rotate, a rotating shaft slidably mounted on the rotating drum along the axial direction of the rotating drum, a vibrating assembly mounted on the rotating shaft, a rotating frame mounted at the top of the rotating shaft, a mounting frame rotatably mounted at the top of the rotating frame, two rollers mounted opposite each other on the mounting frame with a gap, a fixed column mounted inside the housing, and a guide plate mounted at the bottom of the fixed column and passing between the two rollers. The rollers are eccentrically distributed relative to the rotating shaft, the guide plate is inclined and contacts the two rollers, and the rotating shaft passes through the housing.

[0006] Preferably, the vibrating assembly includes multiple sets of stirring blades arranged side by side along the axis of the rotating shaft and a tamping disc disposed at the end of the rotating shaft.

[0007] Preferably, the upper and lower parts of the tamping disc have conical surfaces, and both conical surfaces gradually taper outward from the middle of the tamping disc.

[0008] Preferably, the outer circumferential surface of the rotating shaft has a keyway, and a key is provided at the keyway. The rotating cylinder has a sliding groove distributed along the axial direction, and the key is slidably disposed at the sliding groove.

[0009] Preferably, the guide plate is rotatably mounted at the bottom of the fixed column. The guide plate has a boss portion with multiple adjustment holes distributed in a fan shape around the rotation center axis of the guide plate. The fixed column has a threaded hole and a threaded knob is threadedly connected through the threaded hole. One of the threaded knobs passes through the adjustment hole.

[0010] Preferably, the orientation adjustment mechanism includes a lifting seat, a connecting shaft rotatably mounted on the lifting seat, a gear three mounted on the connecting shaft, a rack slidably mounted on the lifting seat and meshing with the gear three, a hydraulic cylinder two mounted on the lifting seat and driving the rack to move linearly, and a mold frame mounted on the template, the mold frame being mounted on the connecting shaft.

[0011] Preferably, the lifting mechanism includes a lifting frame mounted on a lifting seat, a hydraulic cylinder mounted vertically on a base, and a guide assembly, the top ends of which are connected to the lifting frame.

[0012] On the other hand, the present invention proposes a method for pouring the above-mentioned concrete pouring formwork, comprising the following steps: S1. The template is lifted by the lifting mechanism to leave operating space between the template and the mold shell; S2. Lay steel bars into the mold shell through the operating space and pour concrete; S3. Lower the formwork so that the cover plate fits against the top of the formwork, and use the vibrating mechanism to mix and vibrate the concrete inside the formwork. S4.

Lower the formwork so that the cover plate part 2 fits against the top of the formwork, and wait for the concrete to solidify after mixing and vibration.

[0013] Compared with existing technologies, the present invention has the following beneficial technical effects: The present invention can simultaneously eliminate residual air bubbles in concrete through stirring and vibration, improving the compactness, strength, and quality of concrete molding, and avoiding cracks and hollow areas. In the vibration mechanism, the rotating drum is driven to rotate by a drive component, and the rotating drum drives the rotating shaft to rotate by a key. At the same time, eccentrically distributed rollers roll on the upper and lower sides of the guide plate. During the rolling process, the height changes cyclically, so the rotating shaft can move axially up and down on the rotating drum. The vibration component can rotate and vibrate up and down simultaneously, synchronously stirring and vibrating the concrete in the mold shell, effectively eliminating residual air bubbles.

[0016] Example 1: As Figures 1-5 As shown in the figure, the concrete pouring formwork proposed in this embodiment includes a base 1, a formwork 3, a vibration and stirring mechanism, an orientation adjustment mechanism, and a lifting mechanism.

[0017] The base 1 has a mold shell 2 with an open top, which facilitates the laying of steel bars and the pouring of concrete into the mold shell 2.

[0018] The template 3 includes a cover plate part one and a cover plate part two that are integrally connected and vertically distributed, and one of the two cover plates is placed on the mold shell 2.

[0019] like Figures 1-3 As shown, the vibrating mechanism is installed on the cover plate section 1. When the cover plate section 1 is placed on the mold shell 2, it can stir and vibrate the concrete inside the mold shell 2, eliminating residual air bubbles and improving the density of the concrete after molding. The vibrating mechanism includes a housing 5 installed on the cover plate section 1, a rotating cylinder 9 rotatably mounted on the housing 5, a drive assembly for driving the rotating cylinder 9, a rotating shaft 10 slidably mounted on the rotating cylinder 9 along its axial direction, a vibrating assembly mounted on the rotating shaft 10, a rotating frame 14 at the top of the rotating shaft 10, a mounting frame 15 rotatably mounted at the top of the rotating frame 14, two rollers 16 positioned opposite each other on the mounting frame 15 with a gap, a fixed column 17 inside the housing 5, and a guide plate 18 at the bottom of the fixed column 17 passing between the two rollers 16. The outer circumferential surface of the rotating shaft 10 has a keyway, and a key 11 is provided at the keyway. The rotating cylinder 9 has axially distributed grooves, and the key 11 is slidably mounted at the grooves. The rotating shaft 10 achieves axial sliding with the rotating cylinder 9 through the key 11.

[0020] like Figure 3 As shown, the rollers 16 are eccentrically distributed relative to the rotating shaft 10, and the guide discs 18 are inclined and in contact with the two rollers 16. As the rotating shaft 10 rotates, the rollers 16 can roll at different heights on the guide discs 18, thereby realizing the reciprocating change of the height of the rotating shaft 10. The rotating shaft 10 reciprocates and rises, and the vibrating assembly reciprocates and rises, using the vibrating assembly to mix and vibrate the concrete. The rotating shaft 10 passes through the box body 5, and the vibrating assembly is located on the outside of the box body 5. When the cover plate is in contact with the top of the mold shell 2, the vibrating assembly is located on the inside of the mold shell 2.

[0021] like Figure 3 As shown, the drive assembly includes a motor mount inside the housing 5, a motor 6 mounted on the motor mount, a gear 7 at the output end of the motor 6, and a gear 8 meshing with the gear 7. The gear 8 is mounted on the rotating drum 9. The motor 6 drives the gear 7 to rotate, which in turn drives the gear 8 to rotate. The gear 8 then drives the rotating drum 9 to rotate. The rotating drum 9 drives the rotating shaft 10 to rotate via a key 11. The rotating shaft 10 drives the vibrating assembly to rotate, thus mixing the concrete. Simultaneously, the rotation of the rotating shaft 10 drives the rotating frame 14 to rotate. The rotating frame 14 drives two rollers 16 to move via a mounting frame 15. The rollers 16 roll on an inclined guide plate 18, and their height changes cyclically, enabling the rotating shaft 10 to reciprocate. This causes the vibrating assembly to rise and fall repeatedly during rotation, effectively vibrating the concrete and improving the air bubble elimination effect.

[0022] like Figure 2 and Figure 5 As shown, the vibratory mixing assembly includes multiple sets of mixing blades 12 arranged side-by-side along the axial direction of the rotating shaft 10, and a tamping disc 13 located at the end of the rotating shaft 10. The mixing blades 12 are used for mixing during rotation. The tamping disc 13 has conical surfaces at both the upper and lower parts, and both conical surfaces gradually taper outwards from the center of the tamping disc 13. The reciprocating movement of the tamping disc 13 is used to vibrate and compact the concrete. The two conical surfaces facilitate the flow of concrete materials, preventing concrete residue from remaining on the tamping disc 13. The mixing blades 12 themselves also play a certain role in vibration as they move with the rotating shaft 10.

[0023] like Figure 4 As shown, the orientation adjustment mechanism adjusts the template 3 to the position where either the cover plate part one or the cover plate part two faces the mold shell 2. The orientation adjustment mechanism includes a lifting seat 23, a connecting shaft 27 rotatably mounted on the lifting seat 23, a gear 26 mounted on the connecting shaft 27, a rack 25 slidably mounted on the lifting seat 23 and meshing with the gear 26, a hydraulic cylinder 24 mounted on the lifting seat 23 and driving the rack 25 to move linearly, and a mold frame 4 mounted on the template 3, the mold frame 4 being mounted on the connecting shaft 27.

[0024] like Figure 1 , Figure 2 and Figure 5 As shown, the lifting mechanism adjusts the template 3 so that the cover plate part one fits against the top of the mold shell 2, so that the concrete inside the mold shell 2 can be stirred and vibrated by the vibration mechanism. The cover plate part one can prevent concrete from overflowing. The lifting mechanism can adjust the template 3 so that the cover plate part two fits against the top of the mold shell 2, and wait for the concrete to form after stirring and vibration, which is conducive to the regular formation of concrete. The lifting mechanism includes a lifting frame 22 set on the lifting seat 23, a hydraulic cylinder 20 vertically set on the base 1, and a guide assembly 21. The top ends of the hydraulic cylinder 20 and the guide assembly 21 are both connected to the lifting frame 22. The lifting frame 22 is lifted and lowered by the hydraulic cylinder 20, and guided by the guide assembly 21 during lifting and lowering. The guide assembly 21 includes a guide cylinder vertically set on the base 1 and a guide rod slidably set on the guide cylinder. The top end of the guide rod is set on the lifting frame 22.

[0025] The above-mentioned concrete pouring formwork pouring method includes the following steps: S1. The template 3 is lifted by the lifting mechanism to leave operating space between the template 3 and the mold shell 2; S2. Lay steel bars into the mold shell 2 through the operating space and pour concrete; S3. Lower the formwork 3 so that the cover plate fits against the top of the mold shell 2. Use a vibrating mechanism to stir and vibrate the concrete inside the mold shell 2 to eliminate air bubbles in the concrete. Figure 1 and Figure 2 As shown; S4. The template 3 is raised by the lifting mechanism until the vibrating component is higher than the top of the mold shell 2. The template 3 is adjusted by the orientation adjustment mechanism so that the cover plate faces the mold shell 2. During the adjustment process, the vibrating component will not interfere with the mold shell 2. S5. Lower formwork 3 so that the cover plate part 2 fits against the top of formwork 2, and wait for the concrete to set after mixing and vibration. Figure 5 As shown.

[0026] This embodiment can simultaneously eliminate residual air bubbles in concrete through stirring and vibration, improving the compactness, strength, and quality of the concrete molding, and preventing cracks and hollow areas. In the vibration mechanism, the rotating drum 9 is driven to rotate by the drive component. The rotating drum 9 drives the rotating shaft 10 to rotate via the key 11. At the same time, the eccentrically distributed rollers 16 roll on the upper and lower sides of the guide plate 18. During the rolling process, the height changes cyclically, so the rotating shaft 10 can move axially up and down on the rotating drum 9. The vibration component can rotate and vibrate up and down at the same time, synchronously stirring and vibrating the concrete in the mold shell 2, effectively eliminating residual air bubbles.

[0027] Example 2: Figures 1-5As shown, this embodiment of the concrete pouring template, compared to Embodiment 1, features a guide disc 18 rotatably mounted at the bottom of the fixed column 17. The guide disc 18 has a boss portion with multiple adjustment holes 181 arranged in a fan shape around the rotation axis of the guide disc 18. The fixed column 17 has a threaded hole, through which a threaded knob 19 is threadedly connected. One of the threaded knobs 19 passes through an adjustment hole 181. The guide disc 18 has a disc structure, with its center rotatably connected to the fixed column 17 via a mounting shaft. To adjust the tilt angle of the guide disc 18, the threaded knob 19 is unscrewed from the threaded hole and pulled out of one adjustment hole 181. Then, the guide disc 18 is rotated to align another adjustment hole 181 with the threaded hole. The threaded knob 19 is then passed through the adjustment hole 181 again and screwed into the threaded hole, securing the guide disc 18 in that position. The greater the tilt angle of the guide disc 18 relative to the horizontal plane, the greater the vertical vibration amplitude of the vibrating assembly.

[0028] This embodiment can adjust the tilt angle of the guide plate 18, thereby adjusting the height range of the roller 16 when it rolls on the guide plate 18, thereby adjusting the reciprocating lifting distance range of the rotating shaft 10, and finally adjusting the vibration amplitude of the vibrating assembly.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
