[0001] This invention relates to the field of prefabricated building component technology, specifically to a prefabricated edge component and its production equipment. Background Technology

[0002] With the promotion of prefabricated buildings, precast hollow wall panels of concrete shear wall structures have been widely used. However, the current prefabricated buildings have not yet achieved complete prefabrication. In particular, for high-rise buildings, the requirements for seismic resistance and mechanical performance of the edge parts of concrete shear wall structures are higher. Therefore, the edge parts of existing high-rise buildings are still completed by cast-in-place concrete.

[0003] Patent document CN109736478A discloses a prefabricated composite edge member for L-shaped and T-shaped concrete shear wall structures. The technical solution includes: an edge member area with an L-shaped or T-shaped cross-section, the edge member area consisting of at least two extended edge member units and one corner edge member unit; each extended edge member unit and corner edge member unit has a through hole extending along the height direction; the upper and lower cross-sectional shapes and areas of the through hole are not equal; edge member reinforcing bars extending along the height direction are provided at the four corners of the through hole. The edge member reinforcing bars around each through hole are connected together with edge member stirrups; all edge member stirrups of all extended edge member units and all edge member stirrups of the corner edge member unit on any side of the edge member area are connected together with unit connecting bars.

[0004] The prior art containing the aforementioned patents proposes the structure of prefabricated edge components, but does not propose the corresponding production equipment. Furthermore, considering that edge components can be of various shapes, including I-shaped, L-shaped, and T-shaped, and that different thickness specifications are required for edge components in different applications, the design and manufacture of production equipment for prefabricated edge components currently presents significant challenges.

[0043] Please see Figure 1-17 The present invention provides a prefabricated edge component production equipment, including a mold cavity 1, which is formed by multiple vertical templates 2; multiple partitions, which are disposed in the mold cavity 1 and can be formed into a type, L-shaped or T-shaped cavity 1.1 in conjunction with the vertical templates 2; and a hydraulic device for driving the vertical templates 2 to move to adjust the size of the mold cavity 1.

[0044] Specifically, the production equipment is set on a horizontal ground or a horizontal production table, with the bottom of the upright template 2 fitting against the ground or table. The mold cavity 1 is T-shaped, with all three branches of the T-shape open at their ends. Baffles are placed at certain positions on the three branches of the T-shaped mold cavity 1 to form cavities 1.1 of different shapes. The specific combination methods are as follows: two spaced baffles are set only inside one branch of the T-shaped mold cavity 1 to form a type cavity 1.1; one baffle is used to block an entire branch of the T-shaped mold cavity 1, and baffles are set at the ends of the other two branches to form an L-shaped cavity 1.1; baffles are set inside the three branches of the T-shaped mold cavity 1 to form a T-shaped cavity 1.1; multiple type cavities 1.1 can be combined and produced in the mold cavity 1; one type cavity 1.1 can be combined with one L-shaped cavity 1.1 in the mold cavity 1 for production. The partitions are replaceable parts in various sizes and specifications, selected to fit the internal space of the mold cavity 1 during actual production. A hydraulic device drives the vertical template 2 to move horizontally, thereby adjusting the width of each branch of the T-shaped mold cavity 1, i.e., adjusting the width of cavity 1.1. In practical use, the vertical template 2 is stably set on a horizontal ground or production table, and the hydraulic device is in a stopped state, thus determining the internal space size of the mold cavity 1. Then, according to the shape of the prefabricated edge component to be produced, the appropriate number and size of partitions are arranged into the mold cavity 1 to cooperate with the vertical template 2 to form the required I-shaped, L-shaped, or T-shaped cavity 1.1, thereby producing matching I-shaped, L-shaped, and T-shaped prefabricated edge components. Furthermore, by adding partitions, multiple I-shaped prefabricated edge components can be produced in combination, or a combination of I-shaped and L-shaped prefabricated edge components can be produced. Simultaneously, the hydraulic device can drive the vertical template 2 to move horizontally, making the internal space size of the mold cavity 1 adjustable, thus enabling the production of prefabricated edge components of different thicknesses.

[0045] Compared with the prior art, the prefabricated edge component production equipment proposed in this embodiment of the invention, by setting up partitions, can cooperate with the vertical template 2 to enclose the internal space of the mold cavity 1 into the required I-shaped, L-shaped or T-shaped cavity 1.1, thereby producing matching I-shaped, L-shaped or T-shaped prefabricated edge components; and by adding partitions, combined production can be carried out; and by setting up a hydraulic device, the vertical template 2 can be driven to move, so that the internal space size of the mold cavity 1 is adjustable, thereby producing prefabricated edge components of different thicknesses.

[0046] As a preferred technical solution in this embodiment, the template 2 includes a straight plate 2.1 and two oppositely arranged bent plates 2.2. Specifically, the straight plate 2.1 is usually fixed on a horizontal ground or production table; one side of the bent plate 2.2 is parallel to the straight plate 2.1, and the other side is parallel to the corresponding side of the other bent plate 2.2; the bending angle of the bent plate 2.2 can be set at any angle within the range of 180 degrees according to the actual needs of the edge components. Preferably, when the bending angles of both bent plates 2.2 are set at 90 degrees, the mold cavity 1 can form a right-angled T-shape.

[0047] As a preferred technical solution in this embodiment, the partition includes a first partition 3. The first partition 3 is flatly arranged to fit the surface of the cavity 1.1. Specifically, the arrangement of the first partition 3 ensures that the corresponding end face of the edge member formed in the cavity 1.1 remains flat. The end face of the edge member is the end face that is not used to connect with other prefabricated members. For example, when producing a straight prefabricated edge member in a straight cavity 1.1, one end face of the straight cavity 1.1 is set as the first partition 3, and the corresponding end face of the straight prefabricated edge member is not used to connect with other prefabricated members. When producing an L-shaped prefabricated edge member in an L-shaped cavity 1.1, a partition is needed to separate one entire branch of the T-shaped mold cavity. The first partition 3 is used here, which also ensures that the surface of the L-shaped prefabricated edge member is not used to connect with other prefabricated members.

[0048] As a preferred technical solution of this embodiment, the partition includes a second partition 4. The surface of the second partition 4 that fits into the cavity 1.1 is provided with a plurality of vertically spaced protrusions 5. Specifically, the arrangement of the second partition 4 causes the corresponding end face of the edge member formed in the cavity 1.1 to have a transverse cavity. The end face of the edge member containing the transverse cavity is the end face used to connect with other prefabricated members. For example, when producing a straight-shaped prefabricated edge component in a straight cavity 1.1, one end face of the straight cavity 1.1 is set as a second partition 4, and the corresponding end face forming the straight-shaped prefabricated edge component can form a transverse cavity under the influence of the protrusion 5 for connection with other prefabricated components; when producing an L-shaped prefabricated edge component in an L-shaped cavity 1.1, both end faces of the L-shaped cavity 1.1 are set as second partitions 4, and the corresponding end faces forming the L-shaped prefabricated edge component can form a transverse cavity under the influence of the protrusion 5 for connection with other prefabricated components; when producing a T-shaped prefabricated edge component in a T-shaped cavity 1.1, the three branch end faces of the T-shaped cavity 1.1 are set as second partitions 4, and the corresponding end faces forming the L-shaped prefabricated edge component can form a transverse cavity under the influence of the protrusion 5 for connection with other prefabricated components.

[0049] As a preferred embodiment, the hydraulic device includes a column 6 disposed on the outside of the bending plate 2.2, and a hydraulic cylinder 7 is mounted on the column 6. The output end of the hydraulic cylinder 7 is connected to the bending plate 2.2. Specifically, the hydraulic cylinder 7 hydraulically controls the extension and retraction of its output end to drive the bending plate 2.2 to move, while the straight plate 2.1 does not move, thereby realizing the adjustment of the internal size of the mold cavity 1. In actual use, when the hydraulic cylinder 7 controls the bending plate 2.2 to move relative to the straight plate 2.1, the size of the mold cavity 1 between the straight plate 2.1 and the bending plate 2.2 can be adjusted; when the hydraulic cylinder 7 controls the two bending plates 2.2 to move relative to or towards each other, the size of the mold cavity 1 between the two bending plates 2.2 can be adjusted. The above two adjustment methods can realize the adjustment of the size of the type, L-shaped, or T-shaped cavity 1.1 according to the selection of the cavity 1.1 and their mutual cooperation.

[0050] As a further preferred technical solution of this embodiment, two rows of hydraulic cylinders 7 are arranged on the column 6, respectively corresponding to the two different surfaces of the bending plate 2.2. The output end of the hydraulic cylinders 7 is connected to the bending plate 2.2 through a sliding assembly. Specifically, the bending angle of the bending plate 2.2 is arranged at 90 degrees, that is, when the mold cavity 1 is in a right-angled T shape, the extension and retraction directions of the output ends of the two rows of hydraulic cylinders 7 are perpendicular to the two different surfaces of the bending plate 2.2. The two rows of hydraulic cylinders 7 drive the bending plate 2.2 to move relative to the straight plate 2.1, and drive the bent plate 2.2 connected to it to move relative to another bent plate 2.2. The sliding assembly allows the output end of the hydraulic cylinder 7 to be connected to the bending plate 2.2 in a movable connection manner perpendicular to its extension and retraction direction, thereby eliminating the movement interference caused by both rows of hydraulic cylinders 7 acting on the bending plate 2.2 during operation.

[0051] As a further preferred technical solution of this embodiment, the sliding assembly includes a pulley seat 8 fixedly mounted on the output end of the hydraulic cylinder 7, a pulley 9 mounted on the pulley seat 8, and a limiting guide rail 10 matching the pulley 9 mounted on the bending plate 2.2. Specifically, there are preferably two pulleys 9, which roll against the surface of the bending plate 2.2 to obtain a movement direction parallel to the surface of the bending plate 2.2, so that the output end of the hydraulic cylinder 7 connected thereto can remain perpendicular to the corresponding surface of the bending plate 2.2; the limiting guide rail 10 restricts the rolling direction of the pulley 9, and the limiting guide rail 10 is also used to transmit the tension of the hydraulic cylinder 7 when it retracts to the bending plate 2.2. In practical use, when one of the hydraulic cylinders 7 is activated and its output end is extended or retracted, the bending plate 2.2 can be moved, causing the corresponding bending plate 2.2 to be pulled closer to the column 6 or pushed away from the column 6. At the same time, the pulley 9 connected to the output end of the other hydraulic cylinder 7 rolls in the corresponding limit guide rail 10 to avoid motion interference.

[0052] As a preferred technical solution in this embodiment, a vertically penetrating core block 11 is provided inside the cavity 1.1. Specifically, the core block 11 is usually located in the middle of the cavity 1.1, and each side is spaced apart from the inner wall of the cavity 1.1. The number and shape of the core blocks 11 are preferred according to the shape of different types of cavities 1.1. The core blocks 11 fill the interior of the cavity 1.1, while the other spaces of the cavity 1.1 are used to fill concrete, thereby making the precast edge member hollow in the middle, double-sided overlapping, and with sealed edges at the ends. After the edge member is precast, the core block 11 needs to be removed, and a vertical cavity is formed on the precast edge member. The vertical cavity is used for the vertical connection of the precast parts. The combination of the core block 11 and the cavity 1.1 can produce a double-sided overlapping edge member. The vertical cavity inside is not only used for the vertical connection between precast parts, but also serves as a heat insulation cavity. In addition, the cooperation between the core block 11 and the mold cavity 1 can also be used to produce a double-sided overlapping shear wall with a heat insulation cavity.

[0053] A precast edge component, produced using the aforementioned precast edge component production equipment, includes a mold 12 that matches a cavity 1.1. A reinforcing steel skeleton 13 is provided within the mold 12. Specifically, the reinforcing steel skeleton 13 is positioned in the gap between the cavity 1.1 and the core block 11. Concrete is then poured into the gap between the cavity 1.1 and the core block 11 to form the mold 12. The reinforcing steel skeleton 13 includes vertical reinforcing bars, frame-type tie bars fitted onto the vertical reinforcing bars, and stirrups fitted onto the frame-type tie bars. The vertical reinforcing bars are evenly distributed within the cavity 1.1, avoiding the core block 11. The frame-type tie bars are evenly distributed in the vertical extension direction of the vertical reinforcing bars. The stirrups are positioned in the middle of the frame-type tie bars to prevent them from expanding outwards. Both the frame-type tie bars and the stirrups have portions that span the hollow interior of the mold 12. The tight fit of the core block 11, or the clamping of the stirrups on both sides, ensures that the hollow interior of the mold 12 is formed, thus ensuring that the vertical cavity inside the precast edge component is a single unit.

[0054] As a preferred technical solution of this embodiment, the mold body 12 is provided with a first cavity 14 that matches the core block 11, and the end face of the mold body 12 is provided with a second cavity 15 that matches the protrusion 5. Specifically, the first cavity 14 is a vertical cavity formed on the mold body 12 after the core block 11 is removed, which is used for vertical connection between prefabricated components and can also serve as a heat insulation cavity; the second cavity 15 is a horizontal cavity formed on the end face of the mold body 12 after the protrusion 5 is first inserted and then removed, which is used for horizontal connection between prefabricated edge components and other prefabricated components; the number and height distribution of the second cavities 15 are set according to actual needs; one end of the second cavity 15 is connected to the first cavity 14, and this structure is formed by the protrusion 5 and the core block 11 abutting each other before pouring concrete.

[0055] The vertical connection structure between the upper and lower precast edge components through the first cavity 14 is called the vertical connection node. Its basic structure is as follows: a vertical connecting steel bar is set between the upper and lower precast edge components that are close to each other. The upper and lower ends of the vertical connecting steel bar are respectively inserted into the first cavity 14 of the upper and lower precast edge components and overlap with other steel reinforcement structures in the upper and lower precast edge components to meet the steel reinforcement overlap requirements of high-rise buildings. The vertical connecting steel bar can be fixed by formwork and concrete pouring, and the upper and lower precast edge components can be connected and fixed. Furthermore, a horizontal bar is welded to the middle of the vertical connecting steel bar. The length of the horizontal bar is not less than the width of the first cavity 14. Then, when the vertical connecting steel bar is inserted into the lower precast edge component, the horizontal bar crosses the first cavity 14 to support the lower precast edge component. In addition, multiple vertical connecting bars are usually provided at the upper end of the edge member to connect the upper and lower edge members. The horizontal bars of the multiple vertical connecting bars are connected in a series by a horizontally intersecting point bar, which can prevent the vertical connecting bars from being skewed. In actual use, the multiple vertical connecting bars connected by the point bar first connect to the upper end of the first cavity 14 of the lower precast edge member. At the same time, the horizontal bar is supported on the upper end of the lower precast edge member. Then, the upper precast edge member connects to the upper end of the vertical connecting bars through the first cavity 14 inside it, and clamps the horizontal bar downward under gravity. At this time, the steel structure inside the upper and lower precast edge members can overlap with the vertical connecting bars. Then, the vertical connecting bars can be fixed by formwork and concrete pouring, and the upper and lower precast edge members can be connected and fixed.

[0056] The transverse connection structure between the precast edge component and the double-sided composite wall panel via the second cavity 15 is called the horizontal connection node. Specifically, the structure consists of transverse connecting steel bars running through the second cavity 15, which are rectangular in shape. During the hoisting and movement of the precast edge component, the transverse connecting steel bars slide within the second cavity 15 and are retracted into the first cavity 14, thus not protruding from the connection end face of the precast edge component. This prevents interference between the transverse connecting steel bars and the steel reinforcement structure within the double-sided composite wall panel during the hoisting and lowering of the precast edge component. When the precast edge component is lowered to the same height and close to the double-sided composite wall panel, the transverse connecting steel bars are then... Pulled out from the second cavity 15 and extended into the double-sided composite wall panel, it then laps with the steel reinforcement structure within the double-sided composite wall panel, meeting the steel reinforcement lap requirements for high-rise buildings. Subsequently, the steel reinforcement of the lapped part is anchored by formwork and concrete pouring, thus completing the connection between the precast edge component and the double-sided composite wall panel. In addition, to further ensure the stability of the steel reinforcement lap, vertical steel reinforcement can be added in the first cavity 14 of the precast edge component and in the double-sided composite wall panel after the horizontal connecting steel reinforcement is inserted into the precast shear wall. This vertical steel reinforcement passes through the frame of the horizontal connecting steel reinforcement, thereby further positioning the horizontal connecting steel reinforcement and enhancing the connection stability after concrete pouring.

[0057] The size of the mold cavity 1 is adjustable, making the partitions interchangeable in various sizes and specifications. They are selected to fit the internal space of the mold cavity 1 during actual production. The first partition 3 is a common flat plate, which is simple to mass produce in multiple sizes and is not expensive. However, the second partition 4 is a special plate with protrusions 5, which would have higher production costs for mass production in multiple sizes. In addition, the size range of the prefabricated edge components is wide. Producing the partitions one specification at a time would result in a large number of accessories for the production equipment, which would also cause trouble for the production operation.

[0058] In another embodiment of the present invention, retractable side plates 16 are movably provided on both opposite sides of the second partition plate 4. The ends of the side plates 16 abut against the inner wall of the mold cavity 1. Specifically, the height of the side plates 16 is consistent with the height of the second partition plate 4. The side plates 16 are provided so that their overall width with the second partition plate 4 is adjustable. The abutment of the ends of the side plates 16 against the inner wall of the mold cavity 1 ensures that the second partition plate 4 and the side plates 16 can form a closed blockage in the mold cavity 1, ensuring the side sealing of the cavity 1.1. The connection between the second partition plate 4 and the side plates 16 can preferably be an elastic element connection. Specifically, the elastic element pushes the side plates 16 to extend outward from the second partition plate 4. The maximum length of the two side plates 16 extending outward when no force is applied is such that the overall width of the second partition plate 4 and the two side plates 16 is not less than the maximum adjustable width of the inner wall of the mold cavity 1. In practical use, the side plate 16 allows the second partition 4 to always adapt to the width of the inner wall of the mold cavity 1, thus eliminating the need for multiple specifications of customization, greatly reducing the production cost of equipment accessories, and the elastic connection method makes the width adjustment range of the second partition 4 wider and smoother.

[0059] As a preferred technical solution in this embodiment, two opposing protruding plates 17 are provided at the end of the vertical template 2. A guide rod 18 is provided through the protruding plate 17. One end of the guide rod 18 extends into the mold cavity 1 and is fixedly provided with a connecting plate 19. The connecting plate 19 is connected to the side plate 16. Specifically, based on the right-angled T-shaped mold cavity 1 formed by the vertical template 2, the connection method between the two protruding plates 17 and the vertical template 2 can be divided into two cases: In the first case, one of the two protruding plates 17 is fixedly provided on the end of the straight plate 2.1, while the other protruding plate 17 is movably provided. In the first case, two protruding plates 17 are fixedly installed on the corresponding ends of the two bent plates 2.2; in the second case, the number of guide rods 18 passing through the same protruding plate 17 is not less than two; the connecting plate 19 is close to the inner wall of the mold cavity 1 and is arranged in a vertical strip shape; the connecting plate 19 can move horizontally along the inner wall of the mold cavity 1 by relying on the guide rods 18; the side plate 16 is connected to the connecting plate 19, so that the side plate 16 can be set close to the mold cavity 1, thereby enabling the end of the side plate 16 to keep in contact with the inner wall of the mold cavity 1. In practical use, the bending plate 2.2 is moved and adjusted by the hydraulic cylinder 7. The side plate 16 can be extended and retracted by the convex plate 17, guide rod 18, and connecting plate 19. The side plate 16 keeps in contact with the inner wall of the mold cavity 1, so that the overall width adjustment of the second partition plate 4 and the two side plates 16 can be synchronized with the mold cavity size adjustment caused by the movement of the bending plate 2.2, thus realizing the width self-adaptive function of the second partition plate 4. In addition, the second partition plate 4 is connected to the connecting plate 19 by the side plate 16, and the connecting plate 19 is movably connected to the convex plate 17 by the guide rod 18, so that the second partition plate 4 can also move horizontally in the mold cavity 1 to adjust the external dimensions of the cavity 1.1 it defines.

[0060] As a preferred embodiment, the second partition 4 is provided with a storage groove 20 that matches the side plate 16. The inner wall of the storage groove 20 is connected to the side plate 16 by a first spring 21. Specifically, one end of the side plate 16 is embedded in the storage groove 20 and is provided with a spring groove for storing the first spring 21. Preferably, there are multiple first springs 21, which are horizontally connected between the second partition 4 and the side plate 16 and vertically evenly distributed. The first springs 21 maintain tension between the second partition 4 and the side plate 16, that is, when the side plate 16 is not under force. The side plate 16 moves and retracts into the storage groove 20. Since the side plate 16 is connected to the connecting plate 19 near the inner wall of the mold cavity 1, the side plate 16 extends out of the storage groove 20 under the drive of the connecting plate 19. This causes the first spring 21 to stretch and store elastic potential energy. Since the first spring 21 between the two side plates 16 and the second partition 4 is subjected to balanced force, the second partition 4 can automatically center itself in the mold cavity 1. This causes the protrusion 5 to also center itself in the mold cavity 1, ensuring that the transverse cavity position of the connecting end face of the prefabricated edge component is uniformly centered.

[0061] As a preferred embodiment, a sliding pin 22 is provided on the side plate 16, and an inclined sliding groove 23 matching the sliding pin 22 is provided on the connecting plate 19. A limiting member 24 limiting the height of the side plate 16 is provided at the upper end of the connecting plate 19. Specifically, the upper end of the inclined sliding groove 23 is closer to the second partition plate 4 than its lower end. A threaded head is provided at the end of the sliding pin 22, and the threaded head is connected to a nut through a thread to achieve a limiting connection between the side plate 16 and the connecting plate 19. When the sliding pin 22 is at the upper end of the inclined sliding groove 23, the end of the side plate 16 does not abut against the inner wall of the mold cavity 1, and the lower end of the second partition plate 4 is away from the horizontal ground or production table. When the sliding pin 22 is at the lower end of the inclined sliding groove 23, the end of the side plate 16 abuts against the inner wall of the mold cavity 1, and the lower end of the second partition plate 4 is also pressed down on the horizontal ground or production table. The limiting member 24 can be hinged to the upper end of the connecting plate 19, and then the height of the side plate 16 can be limited or not limited by rotation. The limiting member 24 can also be plugged into the upper end of the connecting plate 19. That is, when it is needed to limit the height of the side plate 16, it is plugged into the upper end of the connecting plate 19 and blocked on the side plate 16. When it is not needed to limit the height of the side plate 16, the upper end of the connecting plate 19 can be removed. In practical use, when the second partition plate 4 needs to be adjusted horizontally within the mold cavity 1, the limiting member 24 does not initially limit the height of the side plate 16. At this time, due to the pulling force applied to the side plate 16 by the first spring 21, the side plate 16 retracts towards the second partition plate 4. The side plate 16 then drives the sliding pin 22 to move closer to the upper end of the inclined slide groove 23 within the inclined slide groove 23, thus preventing the end of the side plate 16 from contacting the inner wall of the mold cavity 1. Simultaneously, the height of the side plate 16 rises, causing the second partition plate 4 to rise away from the horizontal ground or production table. At this point, the second partition plate 4 and the side plate 16 can be suspended as a whole within the mold cavity 1, allowing the second partition plate 4 to move horizontally within the mold cavity 1. When the position is adjusted, it is not hindered by the friction of the inner wall of the mold cavity 1, which facilitates the movement of the second partition 4. When the second partition 4 moves to the appropriate position, the second partition 4 moves down, and the second partition 4 drives the side plate 16 to descend. The side plate 16 drives the sliding pin 22 to move from the upper end to the lower end of the inclined slide groove 23, so that the side plate 16 can slowly extend outward from the second partition 4. Then, when the second partition 4 presses down on the horizontal ground or production table, the end of the side plate 16 also abuts against the inner wall of the mold cavity 1 again. At this time, the height of the side plate 16 is limited by the limiting member 24, thereby making the second partition 4 and the side plate 16 form a stable and closed partition structure in the mold cavity 1, ensuring the sealing of the side of the cavity 1.1.

[0062] In another embodiment of the present invention, a sleeve 25 is rotatably disposed on the convex plate 17, and a screw 26 is axially movable inside the sleeve 25. One end of the screw 26 is hinged to the connecting plate 19, and the other end is threadedly fitted with an internal threaded sleeve 27. The internal threaded sleeve 27 is rotatably connected to the sleeve 25. Specifically, a convex key parallel to its axial direction is provided on the inner wall of the sleeve 25, and a keyway matching the convex key is provided on the screw 26. The arrangement of the convex key and the keyway ensures that only axial movement occurs between the sleeve 25 and the internal threaded sleeve 27. The screw 26 is arranged parallel to the guide rod 18. The internal threaded sleeve 27 rotates and performs a threaded feed action with the screw 26, thereby causing the screw 26 to move axially relative to the sleeve 25, so as to push or pull the connecting plate 19 to move horizontally, that is, to drive the side plate 16 to move.

[0063] As a preferred technical solution in this embodiment, a connecting rod 28 is provided on the sleeve 25, and the ends of the two connecting rods 28 are hinged to the same driving rod 29. A driving wheel 30 is coaxially fixed on the driving rod 29, and a driven wheel 31 is coaxially fixed on the internal threaded sleeve 27. The driving wheel 30 and the driven wheel 31 are connected by a transmission belt 32. Specifically, the length of the connecting rod 28 is satisfied to meet the change in the distance between the branches of the vertical template 2 when the size of the mold cavity 1 is adjusted; that is, the two connecting rods 28 usually form a V-shape. When the mold cavity 1 is gradually adjusted to become larger, the included angle of the V-shape formed by the two connecting rods 28 gradually increases, but when the mold cavity 1 is adjusted to the maximum, the included angle of the V-shape will not exceed 180 degrees. The two internal threaded sleeves 27 are all linked to the same drive rod 29 through the drive wheel 30, the driven wheel 31 and the transmission belt 32. When the drive rod 29 rotates, the thread feed action on the two screws 26 is synchronized, so that the two connecting plates 19 connected to the two side plates 16 of the second partition 4 move synchronously, thereby achieving stable horizontal movement of the second partition 4.

[0064] The protrusion 5 promotes the formation of transverse cavities on the connecting end face of the precast edge component. However, after the component is formed, since the precast component needs to be demolded from above the mold cavity 1, the protrusion 5 will hinder the demolding of the precast component.

[0065] In another embodiment of the present invention, the protrusion 5 is detachably connected to the second partition 4. Specifically, the second partition 4 has multiple vertically arranged points for connecting and installing the protrusion 5. The detachable function of the protrusion 5 allows the position distribution of the protrusion 5 on the second partition 4 to be freely arranged according to actual needs, thereby expanding the applicability of the second partition 4.

[0066] As a preferred embodiment, the second partition 4 is provided with a plurality of vertically spaced movable slots 33. A frame-shaped component 34 is movably disposed within the movable slot 33. A hook-and-loop component 35 matching the frame-shaped component 34 is provided on the protrusion 5. Specifically, when the frame-shaped component 34 is fully retracted into the movable slot 33, its end face can remain flush with the surface of the second partition 4, thereby preventing concrete from entering the movable slot 33 and causing unevenness of the end face of the precast edge component. The hook-and-loop component 35 is hooked from above the frame-shaped component 34, thereby supporting and positioning the protrusion 5 on the second partition 4. The hook-and-loop component 35 includes a hook body disposed within the protrusion 5 and an insertion space disposed at the lower end of the hook body. In actual use, after the frame-shaped component 34 extends out of the movable slot 33, it first inserts into the insertion space at the lower end of the hook body to correspond with the lower side of the hook body. Then, the protrusion 5 moves downward relative to the frame-shaped component 34, so that the hook body can be smoothly hooked onto the frame-shaped component 34.

[0067] As a preferred technical solution in this embodiment, a protruding rod 36 is fixedly provided at one end of the frame member 34 away from the protrusion 5. The end of the protruding rod 36 passes through the second partition 4 and is fixedly provided with a cap 37. A second spring 38 sleeved on the protruding rod 36 is connected between the cap 37 and the second partition 4. Specifically, the setting of the cap 37 limits the length of the frame member 34 connected to the other end of the protruding rod 36 that extends out of the movable groove 33. The second spring 38 keeps pushing the cap 37 away from the surface of the second partition 4, so that the cap 37 is pulled into the movable groove 33 by the protruding rod 36. In practical use, this technical solution involves pressing the cap 37 to bring it close to the second partition 4 and squeezing the second spring 38. The second spring 38 is compressed and stores elastic potential energy. The cap 37 also drives the frame member 34 to extend out of the movable groove 33 via the protruding rod 36. Then, the protrusion 5 is connected to the frame member 34, and the protrusion 5 is hung on the frame member 34 with the help of the hook 35. When the cap 37 is released, the protrusion 5 can be automatically supported and positioned on the second partition 4. Then, during the casting and molding process of the prefabricated edge member, the protrusion 5 will cause the connecting end face of the prefabricated edge member to form a transverse cavity. After the prefabricated edge member is formed, it needs to be removed from the mold cavity 1. If the upper part moves away to achieve demolding, the precast edge component can be directly lifted by the hoisting equipment. Since the protrusion 5 is engaged in the transverse cavity, it can be driven by the rising precast edge component. That is, the hanging part 35 can move upward and disengage from the frame part 34. At the moment of disengagement, the second spring 38 can release elastic potential energy to push the cap 37. The cap 37 then pulls the frame part 34 quickly back into the movable groove 33 with the help of the protrusion rod 36, so that the frame part 34 is completely disconnected from the protrusion 5. The rise of the protrusion 5 is unimpeded, that is, the precast edge component can rise smoothly and be demolded. After that, the protrusions 5 can be removed from the precast edge component one by one.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
