Description
Technical Field
[0001] This invention relates to the field of mechanical engineering, and in particular to a device and method for fabricating fair-faced concrete beams and columns. Background Technology
[0002] Fair-faced concrete is a type of concrete that utilizes the natural texture of the concrete after molding as a finishing effect. After pouring and curing, the concrete surface is smooth and clean without any artificial treatment or decoration, presenting the quality of natural stone. The prefabrication of fair-faced concrete beams and columns is carried out in the workshop, mainly including the production and construction steps such as steel reinforcement cage binding, formwork splicing, fair-faced concrete mixing, pouring of fair-faced concrete beams and columns, curing, demolding, inspection and packaging. When pouring fair-faced concrete beams and columns, pouring equipment is mostly used. In order to improve the efficiency of pouring, most existing pouring equipment adopts electromechanical integrated control to achieve automatic pouring.
[0003] However, the existing electromechanical integrated fair-faced concrete beam and column production and construction methods using pouring equipment are not convenient for adjusting the pouring width according to the width of the fair-faced concrete beam and column, which affects the pouring efficiency. At the same time, it is not convenient to perform leveling operations on the fair-faced concrete after pouring, which also affects the pouring efficiency. Furthermore, when leveling, excess fair-faced concrete is not convenient to collect and reuse, which easily leads to waste of fair-faced concrete. Summary of the Invention
[0004] To address the shortcomings of the existing technology, the present invention provides a device and method for fabricating fair-faced concrete beams and columns, which solves the technical problem that excess fair-faced concrete is difficult to collect and reuse during leveling in the existing fair-faced concrete beam and column fabrication devices.
[0005] In a first aspect, the present invention discloses a device for fabricating fair-faced concrete beams and columns, comprising a movable frame and a storage hopper fixed to the movable end of the movable frame for accommodating fair-faced concrete. The lower part of the storage hopper is tapered to form a feeding section, and the bottom of the feeding section has a discharge port. A collection hopper for collecting excess fair-faced concrete is connected to the feeding section. The collection hopper includes a hopper body that is slidably installed vertically on the feeding section and a sealing plate that is slidably sealed at the bottom of the hopper body horizontally. An inlet for excess fair-faced concrete is opened on the side of the hopper body away from the feeding section. A slurry scraping ramp is provided on the outer wall of the hopper body below the inlet, and the top of the slurry scraping ramp is not lower than the bottom of the opening.
[0006] The invention further improves the fair-faced concrete beam and column fabrication device by comprising a sealing portion for sealing the bottom of the hopper and an opening for excess fair-faced concrete to flow out of the hopper. There is a space between the bottom of the hopper and the fabrication section for the opening to be accommodated. A push plate is connected to the sealing plate for pushing the opening to the bottom of the hopper when discharging material from the outlet. The fabrication section has a slot for the push plate to slide.
[0007] A further improvement of the fair-faced concrete beam and column fabrication device of the present invention is that a first reset assembly for resetting the push plate is vertically slidably installed on the fabric section. The first reset assembly includes a T-shaped rod, a slider, and an elastic element. The T-shaped rod includes a horizontal bar vertically slidably installed on the fabric section and a vertical bar vertically fixed to the horizontal bar away from the fabric section. The slider is slidably sleeved on the horizontal bar. The elastic element is connected between the slider and the vertical bar. The slider is fixed to the push plate.
[0008] A further improvement of the fair-faced concrete beam and column fabrication device of the present invention is that the fabrication section is provided with a support plate for the hopper to be slidably installed, and the support plate and the hopper are connected by an electric telescopic component.
[0009] A further improvement of the fair-faced concrete beam and column fabrication device of the present invention is that the opening is covered with a cover plate, the cover plate is rotatably connected to the bucket body via a rotating rod, and a transmission component for controlling the flipping of the cover plate is installed between the support plate and the bucket body.
[0010] A further improvement of the fair-faced concrete beam and column fabrication device of the present invention is that when the bucket body slides downward, the transmission component drives the cover plate to open. The transmission component includes a gear and a rack that are coaxially fixed with the rotating rod. The rack is connected to the bucket body and meshes with the gear.
[0011] A further improvement of the fair-faced concrete beam and column fabrication device of the present invention is that a striking mechanism for striking the bucket body is connected to the side of the sealing plate. The striking mechanism includes a sliding plate elastically connected to the side of the sealing plate, a row of first protrusions fixed to the side of the bucket body, and a second protrusion fixed to the sliding plate and facing the row of first protrusions.
[0012] A further improvement of the fair-faced concrete beam and column fabrication device of the present invention is that the fabrication section is fixed with an adjustment mechanism for controlling the discharge length. The adjustment mechanism includes a rotating plate for shortening the discharge port length and a rocker wheel for controlling the rotation of the rotating plate. The rotating plate is rotatably connected to the inner wall of the fabrication section via a rotating shaft, and the rotating shaft passes through the fabrication section and is connected to the rocker wheel for transmission.
[0013] Secondly, the present invention also provides a production method using the fair-faced concrete beam and column fabrication device described above, comprising the following steps: moving the storage hopper to above the template of the fair-faced concrete beam and column to be poured using a moving frame; pouring the fair-faced concrete in the storage hopper into the template through the discharge port until the top surface of the fair-faced concrete is higher than the top surface of the template; vertically adjusting the hopper body until the bottom surface of the slurry ramp is flush with the top surface of the template; horizontally sliding the sealing plate until it is sealed at the bottom of the hopper body; moving the storage hopper using the moving frame, while simultaneously scraping excess fair-faced concrete from the inlet into the hopper body through the slurry ramp; during the next fair-faced concrete pouring, horizontally sliding the sealing plate until the bottom of the hopper body is opened, so that the excess fair-faced concrete in the collection hopper and the fair-faced concrete in the storage hopper are poured together.
[0014] The method for manufacturing fair-faced concrete beams and columns of the present invention is further improved in that the sealing plate includes a sealing part and an opening part, and there is a space between the bottom of the hopper and the fabrication section for the opening part to be accommodated. A push plate is fixed on the sealing plate, and a slot is opened on the fabrication section. When the sealing plate is slid horizontally until it is sealed at the bottom of the hopper, the sealing plate is slid horizontally so that the sealing part is sealed at the bottom of the hopper. When the sealing plate is slid horizontally, the fair-faced concrete in the storage hopper flows downward and is discharged from the outlet. During this process, the fair-faced concrete passing through the fabrication section pushes the push plate to slide horizontally along the slot towards one side of the hopper so that the opening part is aligned with the bottom of the hopper so that the excess fair-faced concrete in the hopper can flow out.
[0015] Compared with existing technologies, the advantages of this invention are positive and significant. This invention, through the combination of a collection hopper and a slurry-scraping inclined surface, solves the technical problem in existing fair-faced concrete beam and column fabrication devices where excess fair-faced concrete is difficult to collect and reuse after leveling. This device allows for easy adjustment of the pouring width according to the width of the fair-faced concrete beam and column during pouring, resulting in greater applicability and higher pouring efficiency. Furthermore, after pouring, it facilitates the leveling operation of the fair-faced concrete surface and the collection and reuse of excess concrete, avoiding waste. Attached Figure Description

Detailed Implementation
[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] like Figures 1-6 As shown, the present invention provides a device for fabricating fair-faced concrete beams and columns, including a movable frame 1 and a storage hopper 13 fixed to the movable end of the movable frame 1 for containing fair-faced concrete. The lower part of the storage hopper 13 is tapered to form a feeding section 14. The bottom of the feeding section 14 is provided with a discharge port. A collection hopper for collecting excess fair-faced concrete is connected to the feeding section 14. The collection hopper includes a hopper body 15 that is slidably installed vertically on the feeding section 14 and a sealing plate 18 that is slidably sealed at the bottom of the hopper body 15 horizontally. An inlet for excess fair-faced concrete is provided on the side of the hopper body 15 away from the feeding section 14. A scraping ramp 17 is provided on the outer wall of the hopper body 15 below the inlet. The top of the scraping ramp 17 is not lower than the bottom of the opening.
[0030] The movable frame 1 houses a template 11 body and a reinforcing steel frame 12. The movable frame 1 is known in this technical field and will not be described in detail here. It enables the storage hopper 13 and the discharge port to move in the X and Y directions. The storage hopper 13 is fixed to the moving end of the movable frame 1. A valve is installed between the storage hopper 13 and the concrete placement section 14, which is also known in this technical field and will not be described in detail here. In this embodiment, the concrete placement section 14 is an elongated shape with its axial direction aligned with the width direction of the template 11 to be poured. There are two collection hoppers, located on opposite sides of the concrete placement section 14. Figure 9 As shown, the slurry ramp 17 is a horizontally arranged right-angled triangular prism. The first right-angled face is fixed to the bucket body 15, and the second right-angled face 1702 is flush with the bottom of the bucket body 15. The inclined surface 1701 allows excess fair-faced concrete to pass through. This device, through an adjustment mechanism, allows for easy adjustment of the pouring width according to the width of the fair-faced concrete beams and columns during pouring, resulting in greater applicability and higher pouring efficiency. Furthermore, after pouring, it facilitates the smoothing operation of the fair-faced concrete surface, further increasing pouring efficiency. Additionally, it facilitates the collection and reuse of excess fair-faced concrete, avoiding waste.
[0031] Preferred, such as Figure 6 and Figure 9As shown, the sealing plate 18 includes a sealing portion for sealing the bottom of the hopper 15 and an opening 19 for excess concrete water to flow out of the hopper 15. There is a space between the bottom of the hopper 15 and the fabric section 14 for the opening 19 to be accommodated. A pusher plate 303 is connected to the sealing plate 18 for pushing the opening 19 to the bottom of the hopper 15 when discharging material from the outlet. A slot is provided on the fabric section 14 for the pusher plate 303 to slide. Specifically, the distance between the bottom of the hopper 15 and the fabric section 14 is greater than twice the area of the bottom of the hopper 15, the size of the sealing plate 18 is greater than twice the area of the bottom of the hopper 15, and the opening 19 is provided on the sealing plate 18 at a position between the bottom of the hopper 15 and the fabric section. In this embodiment, there are two pushers 303 and two slots, each corresponding to one of the two sides of the fabric section 14. The hopper 15 is shaped like a bucket, wider at the top and narrower at the bottom, allowing excess fair-faced concrete inside to fall under gravity. The pusher plate 303 is a downward-sloping plate, so that as the fair-faced concrete in the placing section 14 flows down to the formwork 11, the pusher plate 303 decomposes the downward thrust of the fair-faced concrete into a horizontal component, thereby pushing the pusher plate 303 to move outward, thus aligning the opening 19 with the bottom of the hopper 15. The hopper 15 is generally elongated and aligned with the axis of the placing section 14. The cross-sectional dimension of its bottom opening is smaller than that of its top opening, the opening size of the opening 19 is not smaller than the cross-sectional dimension of the bottom opening 16 of the hopper, and the size of the sealing part is not smaller than the cross-sectional dimension of the bottom opening 16 of the hopper. Furthermore, the bottom surface of the push plate 303 is formed with a support block 302 to provide support for the push block. The back of the support block 302 is provided with a first guide rail 304. The cross-section of the first guide rail 304 is T-shaped. The sealing plate 18 is provided with a T-shaped notch 301 that matches the first guide rail 304. The T-shaped notch 301 can slide vertically on the first guide rail 304.
[0032] Preferred, such as Figure 6 and Figure 9As shown, a first reset assembly for resetting the push plate 303 is vertically slidably mounted on the fabric section 14. The first reset assembly includes a T-shaped rod 203, a slider 205, and an elastic element. The T-shaped rod 203 includes a horizontal bar vertically slidably mounted on the fabric section 14 and a vertical bar vertically fixed to the horizontal bar away from the fabric section 14. The slider 205 is slidably sleeved on the horizontal bar. The elastic element connects the slider 205 and the vertical bar, and the slider 205 is fixed to the push plate 303. In this embodiment, the elastic element is a first spring 204, which is sleeved on the horizontal bar. Further, the horizontal bar can also be replaced with a fixed plate, thereby providing more space for the first spring 204 to rest against. When the blocking part is at the bottom of the bucket body 15, the first spring 204 is in a relaxed state with its original length. When the opening 19 moves to the bottom of the bucket body 15, the first spring 204 is in a compressed state. Thus, when no concrete is being fed into the feeding section 14, the elastic force of the first spring 204 will apply force to the slider 205, and the slider 205 will drive the sealing plate 18 and the push plate 303 to return to their original positions. There are two first reset components, which are respectively located at both ends of the sealing plate 18. Furthermore, in order to guide the vertical sliding of the bucket body 15, two guide components are fixed on the side of the fabric section 14. The two guide components are arranged one-to-one with the two first reset components. The guide component includes a second guide rail 201 fixed on the side of the fabric section 14 and a first moving block 202 slidably installed on the second guide rail 201. The vertical rod of the T-shaped rod 203 is vertically fixed on the first moving block 202. The cross-section of the second guide rail 201 is T-shaped. The first moving block 202 has a T-shaped groove that matches the second guide rail 201 along its length. The T-shaped groove can slide vertically on the second guide rail 201.
[0033] Preferred, such as Figures 3-5 and Figure 7 As shown, the fabric section 14 is provided with a support plate 701 for the hopper body 15 to be slidably installed. The support plate 701 and the hopper body 15 are connected by an electric telescopic component. The top of the hopper body 15 is provided with a top plate that seals off the entire internal space of the hopper. The electric telescopic component includes a threaded pipe 704 fixed to the top plate, a motor 706 fixed to the support plate 701, and a threaded rod 705 screwed into the threaded pipe 704. The threaded rod 705 is coaxially fixed to the output shaft of the motor 706. The threaded pipe 704, the threaded rod 705, and the motor 706 are all located on the same axis. Furthermore, a sleeve rod 702 is fixed on the support plate 701, a sleeve 703 is fixed on the top plate, and a sleeve rod 702 is fixed at the bottom of the support plate 701. The sleeve 703 is adapted to the size of the sleeve rod 702 and is sleeved on the outside of the sleeve rod 702. The sleeve 703 and the screw can provide guidance for the vertical sliding of the bucket body 15. The sleeve 703 and the threaded pipe 704 are arranged at intervals.
[0034] Preferred, such as Figure 4 and Figure 7 As shown, the opening is covered with a cover plate 20, which is rotatably connected to the bucket body 15 via a rotating rod 402. A transmission assembly for controlling the rotation of the cover plate 20 is installed between the support plate 701 and the bucket body 15. The cover plate 20 opens when the bucket body 15 slides downward via the transmission assembly, allowing excess concrete to flow into the bucket body 15 through the opening along the slurry ramp 17. It closes when the bucket body 15 slides upward, thus preventing the concrete from flowing out of the opening. Two spaced-apart fixing blocks 401 are provided on the bucket body 15 above the opening. The cover plate 20 is located between the two fixing blocks 401, and the rotating rod 402 passes through the two fixing blocks 401, allowing the rotating rod 402 to rotate freely on the fixing blocks 401.
[0035] Preferred, such as Figure 7 , Figure 9 and Figure 10 As shown, when the bucket body 15 slides downward, the transmission assembly drives the cover plate 20 to open. The transmission assembly includes a gear 501 coaxially fixed with the rotating rod 402 and a rack 502. The rack 502 is connected to the bucket body 15 and meshes with the gear 501. Further, the support plate 701 is provided with an L-shaped stop bar 503 extending from the support plate 701. The first end of the stop bar 503 is fixed to the support rod, and the second end of the stop bar 503 is directly opposite the top of the rack 502. The side of the bucket body 15 is provided with a horizontal L-shaped rod 601. The first side of the L-shaped rod 601 is fixed to the side of the bucket body 15, and a second reset assembly is fixed on the second side of the L-shaped rod 601. The second reset assembly includes a T-shaped guide... The guide rod 602, the second moving block 202, and the second spring 603 are configured as follows: one end of the vertical rod of the guide rod 602 is fixed to the second side rod of the L-shaped rod 601, and the horizontal rod of the guide rod 602 is fixed to the second end of the vertical rod. The second moving block 202 is slidably sleeved on the vertical rod of the guide rod 602. The second spring 603 is connected between the vertical rod and the second side rod of the L-shaped rod 601 and is sleeved on the vertical rod. The second moving block 202 is fixed to the rack 502. The horizontal rod can also be replaced with a plate to increase the contact area of the second spring 603. Furthermore, there are two second reset components, located on opposite sides of the rack 502. When the bucket body 15 moves downward, the rack 502 no longer abuts against the lower end of the stop bar 503. At this time, the rack 502 moves upward under the action of the second spring 603, and drives the gear 501 and the rotating rod 402 to rotate, thereby rotating the cover plate 20 upward to open. When the bucket body 15 moves upward, the rack 502 abuts against the lower end of the stop bar 503, causing the cover plate 20 to rotate and close. At the same time, the second spring 603 is compressed.
[0036] Preferred, such as Figure 10 As shown, a striking mechanism for striking the bucket body 15 is connected to the side of the sealing plate 18. The striking mechanism includes a sliding plate 802 elastically connected to the side of the sealing plate 18, a row of first protrusions 801 fixed to the side of the bucket body 15, and a second protrusion 803 fixed to the sliding plate 802 and directly opposite the row of first protrusions 801. Specifically, a T-shaped guide rod 1001 is fixed to the side of the sealing plate 18. The first end of the vertical rod of the guide rod 1001 is fixed to the side of the sealing plate 18, and the second end of the guide rod 1001 is fixed to a horizontal rod or plate. A sliding plate 802 is slidably sleeved on the vertical rod. A third spring 1002 is connected between the sliding plate 802 and the sealing plate 18. The third spring 1002 is sleeved on the vertical rod. When the first protrusion 801 and the second protrusion 803 are not in contact, the third spring 1002 is in a relaxed state with its original length. When the first protrusion 801 contacts the front end face of the second protrusion 803, the third spring 1002 is in an extended state. Both the first protrusion 801 and the second protrusion 803 are hemispherical, and there are multiple spaced second protrusions 803 in a row of first protrusions 801. During pouring, when the sealing plate 18 moves, it drives the sliding plate 802 and the second protrusion 803 to move synchronously. When the second protrusion 803 abuts against the side wall of the first protrusion 801, it pushes the second protrusion 803 and the sliding plate 802 to move away from the material distribution section 14. At the same time, the third spring 1002 is stretched. When the second protrusion 803 passes the side wall of the first protrusion 801, the sliding plate 802 and the second protrusion 803 can move towards the bucket body 15 under the elastic force of the third spring 1002, and make the second protrusion 803 knock and vibrate against the side wall of the bucket body 15. This process is repeated so that when the clear water concrete temporarily stored in the collection bucket falls through the bottom outlet, it knocks and vibrates against the side wall of the bucket body 15, making the material discharge smoother and more efficient.
[0037] Preferred, such as Figure 4 and Figure 8As shown, the fabric section 14 is fixed with an adjustment mechanism for controlling the discharge length. The adjustment mechanism includes a rotating plate 902 for shortening the discharge port length and a rocker wheel 907 for controlling the rotation of the rotating plate 902. The rotating plate 902 is rotatably connected to the inner wall of the fabric section 14 via a rotating shaft 901, and the rotating shaft 901 extends out of the fabric section 14 and is connected to the rocker wheel 907 in a transmission connection. Furthermore, the rotating shaft 901 extends through the side wall of the fabric section 14 to form an outlet end, on which a worm gear 903 is fixedly fitted. Two symmetrically arranged support blocks 302 are fixed to the side wall of the fabric section 14, and a worm gear 906 is rotatably connected to the side wall of the two support blocks 302 via the rotating shaft 905. The worm gear 906 meshes with the worm gear 903, and a rocker wheel 907 is fixedly connected to one end of the rotating shaft 905. When casting beams and columns of different widths, rotating the rocker wheel 907 causes the rotating shaft 905 and the worm gear 906 to rotate, which in turn drives the worm gear 903, the rotating shaft 901, and the rotating plate 902 to rotate. This facilitates adjustment of the discharge width of the outlet, thereby adjusting the casting width, resulting in greater applicability and higher casting efficiency. Two such adjustment mechanisms are located at opposite ends of the lower part of the fabric section 14.
[0038] On the other hand, such as Figures 1-10 As shown, the present invention also provides a production method using the fair-faced concrete beam and column fabrication device described above, comprising the following steps: moving the storage hopper 13 above the template 11 of the fair-faced concrete beam and column to be poured using the moving frame 1; pouring the fair-faced concrete in the storage hopper 13 into the template 11 through the discharge port until the top surface of the fair-faced concrete is higher than the top surface of the template 11; vertically adjusting the hopper body 15 until the bottom surface of the slurry ramp 17 is flush with the top surface of the template 11; horizontally sliding the sealing plate 18 until it is sealed at the bottom of the hopper body 15; moving the storage hopper 13 using the moving frame 1, while simultaneously scraping excess fair-faced concrete from the inlet into the hopper body 15 through the slurry ramp 17; during the next fair-faced concrete pouring, horizontally sliding the sealing plate 18 until the bottom of the hopper body 15 is opened, so that the excess fair-faced concrete in the collection hopper and the fair-faced concrete in the storage hopper are poured together.
[0039] Preferably, the sealing plate 18 includes a blocking portion and an opening portion 19. There is a space between the bottom of the hopper body 15 and the fabric section 14 for the opening portion 19 to be accommodated. A push plate 303 is fixed on the sealing plate 18, and a slot is opened on the fabric section 14. When the sealing plate 18 is slid horizontally until it blocks the bottom of the hopper body 15, the sealing plate 18 is slid horizontally so that the blocking portion blocks the bottom of the hopper body 15. When the sealing plate 18 is slid horizontally, the clear water concrete in the storage hopper 13 flows downward and is discharged from the outlet. During this process, the clear water concrete passing through the fabric section 14 pushes the push plate 303 to slide horizontally along the slot towards one side of the hopper body 15, so that the opening portion 19 is aligned with the bottom of the hopper body 15, allowing the excess clear water concrete in the hopper body 15 to flow out.
[0040] like Figures 1 to 10 As shown, the production and construction method of fair-faced concrete beams and columns includes the following steps:
[0041] S1: Reinforcing steel cage binding: Fair-faced concrete beams and columns require reinforcing steel cages to enhance their load-bearing capacity. The reinforcing steel cages should be bound according to the design requirements of fair-faced concrete beams and columns. The binding should comply with relevant national standards, and the quantity, diameter, and spacing of the reinforcing steel bars should meet the design requirements.
[0042] S2: Template 11 splicing: Hoist the tied steel reinforcement cage onto the workbench, and then splice, install and support the template 11 according to the dimensions of the fair-faced concrete beams and columns;
[0043] S3: Fair-faced concrete mixing: Fair-faced concrete mixing is the core step in the production of fair-faced concrete beams and columns. Fair-faced concrete beams and columns should be mixed according to the design mix ratio. The quality of fair-faced concrete beams and columns should meet the relevant national standards to ensure the quality of fair-faced concrete beams and columns.
[0044] S4: Casting of fair-faced concrete beams and columns: Casting is carried out in the mold using an electromechanical integrated casting device. The fair-faced concrete should fill the mold evenly to ensure the flatness and accuracy of the fair-faced concrete beams and columns. The casting of fair-faced concrete beams and columns should comply with relevant national standards to ensure the quality of fair-faced concrete beams and columns.
[0045] S5: Curing: Fair-faced concrete beams and columns need to be cured after pouring to ensure the strength and stability of the fair-faced concrete. The curing should be carried out according to the strength grade and curing period of the fair-faced concrete, and the curing environment should meet the relevant national standards.
[0046] S6: Formwork Removal: Formwork needs to be removed from fair-faced concrete beams and columns after curing;
[0047] S7: Inspection and Packaging: After the fair-faced concrete beams and columns are produced, they need to be inspected. The inspection should meet the relevant national standards. After passing the inspection, the fair-faced concrete beams and columns need to be packaged for transportation and storage. The packaging should also meet the relevant national standards.
[0048] When using this device for pouring, firstly, as Figure 1 As shown, a fair-faced concrete is fed into the storage hopper 13 via an automated feeding device. The storage hopper 13 and the placing section 14 are moved by a moving frame 1. Simultaneously, the valve between the storage hopper 13 and the placing section 14 is opened. At this time, the concrete in the storage hopper 13 falls into the formwork 11 through the placing section 14, thus completing the pouring of the beam and column. When pouring beams and columns of different widths, such as... Figure 4 and Figure 8 As shown, rotating the rocker wheel 907 drives the rotation of the rotating shaft 905 and the worm gear 906, which in turn drives the rotation of the worm wheel 903, the rotating shaft 901 and the rotating plate 902, thereby facilitating the adjustment of the discharge width of the material section 14, and thus adjusting the pouring width, making it more applicable and more efficient in pouring.
[0049] After the pouring is completed, such as Figure 7 As shown, the motor 706 is started. The rotation of the motor 706 drives the rotation of the threaded rod 705, which in turn moves the bucket body 15 downward, making the bottom of the scraper ramp 17 flush with the top of the template 11. Then, simultaneously, as... Figure 9 and Figure 10 As shown, the rack 502 no longer abuts against the lower end of the stop bar 503. At this time, the rack 502 moves upward under the action of the second spring 603, and drives the gear 501 and the rotating rod 402 to rotate, thereby opening the cover plate 20 by rotating it upward. Then, the storage hopper 13 and the material distribution section 14 are moved by the moving frame 11, and the hopper body 15 is moved synchronously, thereby moving the slurry ramp 17, so that the surface of the fair-faced concrete can be scraped and leveled. In addition, the excess fair-faced concrete slides into the hopper body 15 through the inclined surface 1701 for temporary storage, which facilitates the scraping operation of the fair-faced concrete surface and makes the pouring efficiency higher.
[0050] After smoothing, as follows Figure 9 and Figure 10 As shown, the electric telescopic component moves the bucket 15 upward, causing the rack 502 to abut against the lower end of the stop bar 503, thus rotating and closing the cover plate 20. Simultaneously, the second spring 603 is compressed. When subsequent pouring occurs, as the fair-faced concrete is discharged through the placing section 14, as... Figure 6As shown, the impact on the push plate 303 causes the push plate 303 to slide outward along the sliding groove and push the sealing plate 18 to move synchronously. At the same time, the first spring 204 is compressed, so that the opening 19 is aligned with the bottom opening 16 of the bucket body. At this time, the fair water concrete temporarily stored in the bucket body 15 falls into the template 11 through the bottom opening 16 and the opening 19 of the bucket body for use, thereby avoiding the waste of fair water concrete.
[0051] And, as Figure 10 As shown, when the sealing plate 18 moves, it drives the sliding plate 802 and the second protrusion 803 to move synchronously. When the second protrusion 803 abuts against the side wall of the first protrusion 801, it pushes the second protrusion 803 and the sliding plate 802 to move away from the bottom opening 16 of the bucket. At the same time, the third spring 1002 is stretched. When the second protrusion 803 passes the side wall of the first protrusion 801, the sliding plate 802 and the second protrusion 803 can move towards the bottom opening 16 of the bucket under the elastic force of the third spring 1002, and make the second protrusion 803 knock and vibrate the side wall of the bucket 15. This process is repeated so that when the fair-faced concrete temporarily stored in the bucket 15 falls through the bottom opening 16 of the bucket, it knocks and vibrates the side wall of the bottom opening 16 of the bucket, making the material discharge smoother and more efficient.
[0052] This invention solves the technical problem in existing fair-faced concrete beam and column fabrication devices where excess fair-faced concrete is difficult to collect and reuse after leveling by combining a collection hopper with a slurry-scraping inclined surface. This device allows for easy adjustment of the pouring width according to the width of the fair-faced concrete beam and column during pouring, making it more versatile and efficient. Furthermore, after pouring, it facilitates the leveling of the fair-faced concrete surface and the collection and reuse of excess concrete, avoiding waste.
