Description

Technical Field

[0001] This invention relates to the field of prefabricated housing construction technology, and in particular to a mold for prefabricated concrete components. Background Technology

[0002] Precast concrete houses have advantages such as high construction efficiency, controllable quality, energy saving and environmental protection, and flexible design. Due to these advantages, they are widely used in modern housing construction. In the process of producing concrete components, the bundled steel cages are installed in precast molds, a certain amount of concrete is poured into the molds, and then it is cured before use. After the concrete is poured into the molds, it is vibrated to eliminate air bubbles and voids. However, during the vibration process, large aggregate particles in the concrete will settle at the bottom of the mold, causing a large number of honeycomb pits on the surface of the finished product, which will affect the appearance and quality of the finished product. Furthermore, when demolding concrete components, workers need to use actions such as tapping to complete the demolding, which will also damage the surface of the finished component and affect the product quality. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention discloses a mold for precast concrete components for houses. The present invention improves the quality and production efficiency of finished concrete components by setting baffles, filters and guide rails on a fixed frame, and setting a driving device and a limiting device on the guide rails.

[0004] To achieve the aforementioned objective, the present invention employs the following technical solution: A precast concrete component mold includes a fixed frame, baffles, a filter screen, a guide rail, a drive device, and a limiting device. Baffles are provided at both ends of the fixed frame and are fixed to the fixed frame with bolts. A filter screen is provided above the fixed frame to filter aggregates in the concrete with a diameter larger than its pore size. A guide rail is provided at one end of the fixed frame. A drive device and a limiting device are sequentially mounted on the guide rail and slidably connected. A horizontally positioned support rod is provided on the drive device, positioned below the filter screen. The drive device controls the horizontal movement of the support rod to open the filter screen above. The end of the support rod passes through the limiting device, which is used to maintain the horizontal movement of the support rod.

[0005] The baffle is arranged longitudinally, and the baffles at both ends of the fixed frame are symmetrically arranged. The baffles are provided with reinforcing plates, and the reinforcing plates of the two baffles are symmetrically arranged. The two reinforcing plates are distributed with symmetrically arranged perforations.

[0006] The fixing frame is a U-shaped structure, including a base plate and side plates. Two side plates are symmetrically arranged on the upper surface of the base plate and are hinged to the base plate. Slide grooves are symmetrically distributed on both sides of the upper surface of the base plate, and arc-shaped connecting plates are distributed on the lower surface of the side plates. A horizontally arranged limiting shaft is provided at the lower end of the connecting plate. The connecting plate drives the limiting shaft to move up and down in the slide groove, and the two ends of the limiting shaft are locked on both sides of the top surface of the slide groove.

[0007] The outer surface of the side plate is provided with reinforcing ribs arranged in an alternating pattern. Hydraulic cylinders are also provided on the outer surface of the side plate. The upper end of the hydraulic cylinder is hinged to the outer surface of the side plate, and the lower end of the hydraulic cylinder is hinged to the ground on both sides of the fixed frame.

[0008] The upper surface of the side plate is equidistantly arranged with longitudinally arranged fixing rods. The fixing rods above the two side plates are symmetrically arranged. Each fixing rod on one side is provided with a transversely arranged connecting shaft, and a filter screen is distributed on the connecting shaft. A transversely arranged connecting rod is provided between two opposite fixing rods on both sides. The two ends of the connecting rod are connected to the adjacent fixing rod by bolts. A limiting ring is provided in the middle of the connecting rod. Each limiting ring above the fixing frame is arranged on the same axis.

[0009] The filter screen is set between two adjacent fixed rods. A fixed ring is distributed at one end of the filter screen. The fixed ring is sleeved on the connecting shaft and rotatably connected to the connecting shaft. The filter screens on both sides of the connecting shaft are symmetrically arranged, with one end of the two adjacent filter screens being lower than the other end.

[0010] The filter screen has a longitudinally arranged support plate at its lower end, and a magnet is provided on the outer surface of the support plate. The magnets of the two support plates attract each other.

[0011] The driving device includes a first fixed frame, a first support frame, a connecting pipe, a sleeve, and a motor. The first fixed frame is mounted on a guide rail and is slidably connected to the guide rail. The first support frame and the motor are located above the first fixed frame. The connecting pipe is located at the upper end of the first support frame. The connecting pipe and the limiting ring are arranged on the same axis. A rotatably connected sleeve is located inside the connecting pipe. The sleeve is coaxial with the connecting pipe and has an internal thread on its inner wall. The motor and the sleeve are driven by a chain drive through a sprocket and a chain. A support rod is located inside the sleeve.

[0012] The support rod and the sleeve are coaxially arranged. The outer surface of the support rod is provided with external threads. The support rod and the sleeve are threadedly connected. The upper end of the side of the support rod is provided with an axially arranged groove. The lower end of the support plate is set in the groove.

The support tube and the connecting tube are arranged on the same axis. The strut passes through the support tube. A scraper is provided on the inner wall of the support tube. The scraper is set in a slot and is adapted to the slot.

[0014] The precast concrete component mold of this invention is highly practical and very convenient to use. By setting a filter screen above the fixed frame, it filters out larger-diameter aggregates in the concrete, avoiding uneven concrete caused by the sedimentation of large aggregates during vibration, reducing the probability of honeycomb and pitting on the component surface, and improving component quality. By setting hydraulic cylinders on the side plates to control the opening and closing of the side plates, it is convenient for demolding later. By setting support rods, drive devices and limiting devices, it is easy to open the filter screen, which facilitates the addition of large aggregates during vibration and improves work efficiency.

[0016] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0017] Combined with appendix Figures 1-8A precast concrete component mold includes a fixed frame 1, baffles 2, a filter screen 12, a guide rail 4, a driving device, and a limiting device. Both ends of the fixed frame 1 are equipped with baffles 2, which are fixed to the fixed frame 1 by bolts. The reinforcing cage of the concrete component is installed inside the fixed frame 1. The filter screen 12 is located above the fixed frame 1, filtering aggregates in the concrete with a diameter larger than its pore size. One end of the fixed frame 1 is equipped with a guide rail 4, and a driving device and a limiting device are sequentially mounted on the guide rail 4. The driving device is equipped with a horizontally arranged support rod 17, positioned below the filter screen 12. The driving device controls the horizontal movement of the support rod 17 to open the upper filter screen 12. The end of the support rod 17 passes through the limiting device, which is used to maintain the horizontal movement of the support rod 17.

[0018] The baffle 2 is arranged longitudinally, and the baffles 2 at both ends of the fixed frame 1 are symmetrically arranged. The baffle 2 is provided with a reinforcing plate 19. The reinforcing plates 19 of the two baffles 2 are symmetrically arranged, and the two reinforcing plates 19 are distributed with symmetrically arranged through holes 20. The steel wire of the concrete component passes through the corresponding through holes 20 and is then fixed.

[0019] The fixed frame 1 has a U-shaped structure and includes a base plate 21 and side plates 22. The upper surface of the base plate 21 is symmetrically provided with two side plates 22, which are hinged to the base plate 21. The upper surface of the base plate 21 has symmetrically distributed sliding grooves 25 on both sides. The lower surface of the side plates 22 has arc-shaped connecting plates 26. The lower end of the connecting plate 26 is provided with a horizontally arranged limiting shaft 27. The connecting plate 26 drives the limiting shaft 27 to move up and down in the sliding groove 25. The two ends of the limiting shaft 27 are stuck on both sides of the top surface of the sliding groove 25. The limiting shaft 27 prevents the connecting plate 26 from coming out of the sliding groove 25 and prevents the side plates 22 from separating from the base plate 21.

[0020] The outer surface of the side plate 22 is provided with reinforcing ribs 13, which are staggered. The reinforcing ribs 13 reduce the deformation of the side plate 22 after being squeezed, thereby improving the quality of the finished component. The outer surface of the side plate 22 is provided with hydraulic cylinders 3. The upper end of the hydraulic cylinder 3 is hinged to the outer surface of the side plate 22, and the lower end of the hydraulic cylinder 3 is hinged to the ground on both sides of the fixed frame 1. By extending and retracting the hydraulic cylinder 3, the angle between the side plate 22 and the bottom plate 21 is adjusted. After the two side plates 22 open outward, it is convenient for the concrete component to be demolded.

[0021] The upper surface of the side plate 22 is equidistantly arranged with longitudinally arranged fixing rods 10. The fixing rods 10 above the two side plates 22 are symmetrically arranged. Each fixing rod 10 on one side is provided with a transversely arranged connecting shaft 24. The connecting shaft 24 is provided with a filter screen 12. A transversely arranged connecting rod 11 is provided between two opposite fixing rods 10 on both sides. The two ends of the connecting rod 11 are connected to the adjacent fixing rod 10 by bolts. A limiting ring 23 is provided in the middle of the connecting rod 11. Each limiting ring 23 above the fixing frame 1 is arranged on the same axis. The distance between the fixing rods 10 is maintained by the connecting rod 11, thereby reducing the amplitude of deformation of the mold.

[0022] The filter screen 12 is disposed between two adjacent fixed rods 10. One end of the filter screen 12 is provided with a fixed ring 28, which is sleeved on the connecting shaft 24 and rotatably connected to the connecting shaft 24. The filter screens 12 on the two connecting shafts 24 are symmetrically arranged. The adjacent end of the two filter screens 12 is lower than the other end. The concave position of the two filter screens 12 makes it easy for large particles of aggregate to fall on the filter screen 12.

[0023] The lower end of the filter screen 12 is provided with a longitudinally arranged support plate 29. The outer surface of the support plate 29 is provided with a magnet 30. The magnets 30 of the two support plates 29 attract each other and temporarily fix the two filter screens 12 through the magnets 30, which facilitates the installation of the support rod 17.

[0024] The driving device includes a first fixed frame 5, a first support frame 6, a connecting pipe 15, a sleeve 16, and a motor 14. The first fixed frame 5 is mounted on the guide rail 4 and is slidably connected to the guide rail 4. The first support frame 6 and the motor 14 are mounted above the first fixed frame 5. The connecting pipe 15 is mounted on the upper end of the first support frame 6. The connecting pipe 15 and the limiting ring 23 are mounted on the same axis. The sleeve 16 is rotatably connected inside the connecting pipe 15 and is coaxial with the connecting pipe 15. The inner wall of the sleeve 16 is provided with internal threads. The motor 14 and the sleeve 16 are chain driven by a sprocket and a chain. The support rod 17 is mounted inside the sleeve 16. The motor 14 drives the sleeve 16 to rotate inside the connecting pipe 15.

[0025] The support rod 17 is coaxially arranged with the sleeve 16. The outer surface of the support rod 17 is provided with external threads. The support rod 17 is threadedly connected to the sleeve 16. The upper side of the support rod 17 is provided with an axially arranged groove 18. The lower end of the support plate 29 is set in the groove 18. When the sleeve 16 is rotated, the support rod 17 moves to one end. After the lower end of the support plate 29 slides out of the groove 18, the large particles of aggregate above the filter screen 12 press the two filter screens 12 open and fall into the lower fixed frame 1.

[0026] The limiting device is located at the end of the driving device away from the fixed frame 1. At least one limiting device is provided on the guide rail 4. The limiting device includes a second fixed frame 7, a second support frame 8, a support tube 9, and a scraper 31. The second fixed frame 7 is slidably connected to the guide rail 4. The second support frame 8 is located above the second fixed frame 7. The upper end of the second support frame 8 is provided with a support tube 9. The support tube 9 and the connecting tube 15 are arranged on the same axis. The strut 17 passes through the support tube 9. The support tube 9 keeps the strut 17 and the connecting tube 15 coaxial, so that the sleeve 16 can drive the strut 17 to move. The inner wall of the support tube 9 is provided with a scraper 31. The scraper 31 is located in the slot 18. The scraper 31 is adapted to the slot 18. The scraper 31 scrapes away the concrete entering the slot 18 and can also maintain the position of the slot 18.

[0027] The precast concrete component mold described in this embodiment involves hoisting the reinforcing cage of the concrete component into a fixed frame 1 and fixing it in place. The baffles 2 at both ends are then fixed with bolts. The steel wire of the concrete component passes through the corresponding through holes 20 and is fixed. After the reinforcing cage is installed, a connecting rod 11 is installed on the fixed rod 10. The connecting rod 11 maintains the distance between the fixed rod 10 and the mold, reducing the deformation amplitude. The motor 14 is started, driving the sleeve 16 to rotate within the connecting pipe 15. The rotation of the sleeve 16 causes the support rod 17 to move laterally through each limiting ring 23, fixing the support rod 17 below the filter screen 12. This fixes the lower ends of each support plate 29 within the slot 18. The filter screens 12 on both sides are then unfolded, and concrete is poured into the fixed frame 1. The filter screen 12 filters out aggregates with a diameter larger than its pore size from the concrete, placing them at the top. The recesses at opposite ends of the filter screens 12 facilitate the falling of large aggregate particles above the filter screens 12. Some large aggregate particles fall into the fixed frame 1 through the gaps between adjacent filter screens 12. After pouring, the concrete is vibrated with a vibrator. During the vibration process, the support rod 17 moves in the opposite direction. During the movement, the scraper 31 scrapes away the concrete entering the slot 18, while also maintaining the position of the slot 18. After the lower end of the support plate 29 slides out of the slot 18, the large aggregate particles above the filter screens 12 press the two filter screens 12 open and fall into the fixed frame 1 below. Through vibration, the large aggregate particles sink, so that they can be evenly distributed, ensuring the quality of the concrete component. After vibration, curing can be carried out. After the concrete component is completed, demolding is carried out. The baffles 2 at both ends and the connecting rod 11 are removed, and the hydraulic cylinder 3 is controlled to retract, opening the two side plates 22 outward to facilitate the demolding of the concrete component.

[0028] The parts of this invention not described in detail are prior art. Although the invention has been specifically shown and introduced in conjunction with preferred embodiments, there are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of the invention.
