Using this patented device to produce prefabricated walls facilitates the processing and molding of prefabricated walls and other components, reducing labor intensity. However, there are still issues such as difficulty in demolding.

[0004] In addition, existing prefabricated walls, especially hollow shear walls, have problems such as large wall panels that make transportation inconvenient, easy leakage at the joints with other structures, and low connection strength.

Each reinforcement bar extends from each reinforcement hole on the corresponding side mold. A center hole mold is installed on the bottom mold. The driving mechanism drives the side mold along the guide rail to approach the reference mold. The side mold, the reference mold and the intermediate molds cooperate to fix the bottom mold and the side mold of each forming area, and form a forming casting cavity in each forming area. Step 2: pouring concrete into each forming casting cavity; Step 3: Before the concrete in each forming and pouring cavity is completely solidified and set, a groove mold is used to press down on the upper end surface of the formed hollow shear wall to form a connecting groove on the upper end surface of the hollow shear wall. The connecting groove is arranged along the distribution direction of the two side molds and communicates with each through hole; The fourth step is to disconnect the side molds from the adjacent first intermediate molds after the concrete in each molding and casting cavity solidifies and takes shape, and the driving mechanism drives the side molds away from the intermediate molds to expose the hollow shear wall formed in the first molding area. After the hollow shear wall is taken out, the driving mechanism drives the side molds close to the intermediate mold, connects the side molds with the adjacent first intermediate molds and disconnects the first two intermediate molds adjacent to the side mold. The driving mechanism drives the side molds and one intermediate mold away from the remaining intermediate molds to expose the hollow shear wall formed in the second molding area. After the hollow shear wall is taken out, the driving mechanism drives the side molds and one intermediate mold close to the remaining intermediate molds, connects the first two intermediate molds adjacent to the side mold and disconnects the second intermediate mold adjacent to the side mold from the third intermediate mold.

The rotary arm rotates relative to the vertical rod and drives the pressure plate to move back and forth between the pressing position and the avoidance position. A locking groove is provided on the locking plate. When the pressure plate is in the pressing position, the rotary arm is embedded in the locking groove. In step 4, before the hollow shear wall is taken out, the pressure plates of each fixing mechanism corresponding to the forming area are moved to the avoidance position. The center hole mold can be fixed by the fixing mechanism to prevent the center hole mold from being displaced by the impact of concrete, which affects the quality of the final product.

[0013] As an optional technical solution of the present invention, the side formwork is provided with a plurality of demolding screw holes, into which demolding screws are screwed. In step five, when separating the hollow shear wall from the side formwork, the demolding screws are rotated to separate the side formwork from the side end surface of the hollow shear wall. The demolding screws provided on the side formwork can quickly separate the side formwork from the hollow shear wall.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0022] Example 1 For the process of producing hollow shear walls using vertical forming equipment, please refer to Figure 1-Figure 5 The vertical forming device includes a base 1, a reference mold 2, a side mold 3, an intermediate mold 4, a bottom mold 5, a side mold 6, and a center hole mold 7. The base 1 is provided with a guide rail. The reference mold 2 is fixedly provided on the base 1 and is located at the end of the guide rail. The base 1 is provided with a side mold 3. The side mold 3 cooperates with the guide rail and can move along the guide rail toward and away from the reference mold 2.

[0023] At least one intermediate mold 4 is arranged on the base 1 between the side mold 3 and the reference mold 2. Each intermediate mold 4 cooperates with the guide rail and can move along the guide rail. When there is one intermediate mold 4, the molding area is between the intermediate mold 4 and the side mold 3, and between the intermediate mold 4 and the reference mold 2. When there are two or more intermediate molds 4, the molding area is set between the side mold 3 and the adjacent intermediate mold 4, between the reference mold 2 and the adjacent intermediate mold 4, and between the two adjacent intermediate molds 4. Each molding area is provided with a bottom mold 5, and two side molds 6 are arranged on the bottom mold 5. A center hole mold 7 is also arranged between the two side molds 6 in each molding area. When the bottom mold 5 is connected to the two inner walls of the molding area, the space surrounded by the upper end face of the bottom mold 5, the inner end faces of the two side molds 6, the outer end face of the center hole mold 7 and the inner end face of the molding area in the molding area is a molding casting cavity. The required hollow shear wall can be formed by pouring concrete into the casting molding cavity. The bottom mold 5 and side molds 6 are of equal width, and the side mold 3 approaches the reference mold 2 along the guide rail. The side mold 3, the reference mold 2 and the intermediate molds 4 cooperate to clamp and fix the bottom mold 5 and side molds 6 of each molding area, thereby forming a molding casting cavity in each molding area.

[0024] The side mold 3 is detachably connected to the adjacent middle mold 4 and between two adjacent middle molds 4. A driving mechanism 8 is also provided on the base 1. The driving mechanism 8 is preferably a telescopic component in the form of an oil cylinder. The driving mechanism 8 drives the side mold 3 or drives the side mold 3 and a specified number of middle molds 4 to move along the guide rail to realize mold closing and mold opening during the production process. The mold closing and mold opening are driven by the driving mechanism 8, which can reduce the labor intensity of personnel and facilitate smooth production.

[0025] The reference mold 2 is also provided with a clamping mechanism 12, which is connected to the side molds 3. During the casting and forming process of the hollow shear wall, the clamping mechanism 12 tightly pulls the side molds 3, locking the side molds 3 and each intermediate mold 4, preventing the side molds 3, intermediate molds 4, and other components from tilting or moving due to concrete impact or concrete solidification, thereby ensuring the quality of the wall panel 13. The clamping mechanism 12 includes a clamping telescopic member and a clamping arm. The clamping telescopic member is connected to the reference mold 2 and rotates relative to the reference mold 2. The telescopic portion of the clamping telescopic member is hinged to the clamping arm, which includes at least two sequentially hinged clamping rods. The clamping arm is hinged to the side molds 3. Preferably, the clamping mechanism 12 is provided on both opposing sides of the reference mold 2, and each side is provided with at least two clamping mechanisms 12.

[0026] In order to facilitate the connection or disconnection between the side mold 3 and the adjacent middle mold 4, and between two adjacent middle molds 4, connecting seats 9 are provided on both sides of the side mold 3 and each middle mold 4. The connecting seats 9 extend out of the molding area, and a connecting groove 10 is provided on the connecting seat 9. The two adjacent connecting seats 9 are detachably connected through a connecting piece. The connecting piece passes through the connecting grooves 10 corresponding to the two adjacent connecting seats 9 and connects the two connecting seats 9. The connection between the two connecting seats 9 can be disconnected by disconnecting the connecting piece from one or two connecting seats 9.

[0027] In order to further facilitate the connection and disconnection of two adjacent connecting seats 9, a connecting groove 10 is provided at the side of the connecting seat 9. The connecting groove 10 is an oblique groove extending obliquely downward. The connecting piece can be provided in the form of a limiting portion provided at both ends, and the limiting portion cannot pass through the limiting portion of the connecting groove 10. As an example, the connecting piece includes a screw and two nuts. The screw passes through the connecting grooves 10 corresponding to the two adjacent connecting seats 9. The two nuts are screwed on the connecting piece and serve as limiting portions. The connecting piece can also be provided in the form of a limiting portion formed by bending at both ends. When the two adjacent connecting seats 9 are connected, the connecting piece is simultaneously embedded in the two connecting grooves 10 and the two connecting grooves 10 are located between the two limiting portions. When the two adjacent connecting seats 9 are disconnected, the connecting piece can be taken out along the connecting groove 10. The form of the connecting groove 10 extending obliquely downward not only facilitates the installation and removal of the connecting piece, but also prevents the connecting piece from accidentally falling off.

[0028] At least two connection grooves 10 are provided on the side of the connection seat 9 , and adjacent connection seats 9 are connected by at least two connecting pieces, thereby improving the connection effect between the side mold 3 and the adjacent middle mold 4 and between two adjacent middle molds 4 .

[0029] The bottom mold 5 is independent of the side molds 3 and the middle mold 4. The bottom mold 5 cooperates with the guide rail and can move along the guide rail. The bottom of the bottom mold 5, the side molds 3, and the middle mold 4 are all provided with a pulley mechanism, which cooperates with the guide rail. Specifically, the guide rail is a T-shaped rail or an I-shaped rail. The pulley mechanism includes a pulley seat, an upper pulley, and a lower pulley. The pulley seat has a through groove that runs through the bottom surface and two opposite side end surfaces of the pulley seat. The upper pulley is arranged in the through groove. The lower pulleys are arranged on the inner walls of the two opposite sides of the through groove. The two lower pulleys are symmetrical and have a gap between them. When the pulley mechanism cooperates with the guide rail, the upper pulley is supported on the upper track surface of the guide rail. The two lower pulleys are respectively on both sides of the guide rail and cooperate with the two side end surfaces of the guide rail or the lower end surface of the upper track surface. The cooperation between the upper pulley and the two lower pulleys allows the pulley seat to move along the guide rail and effectively reduces the risk of derailment, thereby realizing the movable installation of the bottom mold 5, the side mold 3, and the middle mold 4. Furthermore, a limit slot is provided on the outer wheel surface of the upper pulley along the circumferential direction, the top of the guide rail is embedded in the limit slot and the upper track surface cooperates with the part of the upper pulley in the limit slot, further limiting the direction of movement of the pulley seat along the guide rail.

[0030] See also Figure 5 The bottom mold 5 is provided with positioning holes, and there are one or more positioning holes, which are determined according to the number of center holes of the hollow shear wall to be produced. Each center hole mold 7 corresponds to each positioning hole, and the bottom end of the center hole mold 7 is inserted into the positioning hole to realize the positioning and fixation of the center hole mold 7. The bottom end of the center hole mold 7 is set to an inverted frustum or an inverted cone-shaped tip to facilitate the rapid insertion of the center hole mold 7 into the positioning hole.

[0031] See also Figure 4 and Figure 5 In order to fix the position of each center hole mold 7 and prevent the hole mold 7 from being displaced by the impact of concrete during pouring, a fixing mechanism 11 is provided above the forming area at the position corresponding to each center hole mold 7. When the fixing mechanism 11 is in the forming area between the side mold 3 and the adjacent middle mold 4, the fixing mechanism 11 is installed through the side mold 3 and the middle mold 4. When the fixing mechanism 11 is in the forming area between the reference mold 2 and the adjacent middle mold 4, the fixing mechanism 11 is installed through the reference mold 2 and the middle mold 4. When the fixing mechanism 11 is in the forming area between two adjacent middle molds 4, the fixing mechanism 11 is installed through the two middle molds 4.

[0032] Specifically, the fixing mechanism 11 includes a vertical rod, a rotary arm, a locking plate and a pressure plate. The vertical rod and the locking plate are respectively on both sides of the forming area. A rotary arm is provided on the vertical rod, and the rotary arm can rotate horizontally relative to the vertical rod. A screw hole is provided on the rotary arm and a screw is provided in the screw hole. The screw is vertically arranged. A pressure plate is provided at the bottom end of the screw. The pressure plate and the screw are rotatably connected so that the pressure plate can rotate relative to the screw and adjust the plate surface angle. The rotation of the screw can drive the pressure plate to rise and fall. The rotary arm rotates relative to the vertical rod and drives the pressure plate to move back and forth between the pressing position and the avoidance position. The locking plate is provided with a screw hole. There is a locking groove. When the rotary arm drives the pressure plate to move to the pressing position, the rotary arm is embedded in the locking groove, and the pressure plate is located above the corresponding middle hole mold 7. At this time, the screw is rotated to adjust the height of the pressure plate to press the pressure plate onto the middle hole mold 7, and press the middle hole mold 7 into the fixing hole to fix the middle hole mold 7; after the hollow shear wall in the forming area is formed, the screw is rotated to drive the pressure plate to lift, and after the pressure plate is separated from the middle hole mold 7, the rotary arm is rotated to drive the pressure plate to move to the avoidance position. At this time, the pressure plate is at the side of the forming area, leaving the space above the forming area, which is convenient for removing the hollow shear wall from the forming area.

[0033] In order to adapt to the production and use of various types of hollow shear walls, the spacing between the side molds 6 on each bottom mold 5 is adjustable. As a specific example, a plurality of mounting holes are provided on the bottom mold 5 and / or the middle mold 4 along the long side direction, and the side molds 6 are connected to the bottom mold 5 and the middle mold 4 by bolts and other components. The side molds 6 can be adjusted on the bottom mold 5 to adjust the spacing between the side molds 6. As another specific example, an adjustment base is provided at both ends of the bottom mold 5, and an adjustment screw is provided on the adjustment base. The adjustment screw is provided along the long side direction of the bottom mold 5 and can rotate. The end of the adjustment screw is rotatably connected to the side mold 6. Rotating the adjustment screw can adjust the position of the side mold 6 along the long side direction of the bottom mold 5, thereby adjusting the spacing between the side molds 6.

[0034] A cushion layer is provided on the bottom form 5 , and holes are reserved on the cushion layer corresponding to the positioning holes. When the height of the hollow shear wall needs to be adjusted, it can be achieved by arranging a certain number of cushion layers.

[0035] The inner end surface of the side mold 6 is also provided with a side hole punch, which is used to form the side hole of the hollow shear wall during casting. The side hole punch can be configured in a frustum shape, which can form a tapered side hole on the side of the hollow shear wall, facilitating demoulding. The side hole is formed at the corresponding through hole and does not communicate with the through hole. The separation between the side hole and the through hole is relatively thin. When the hollow shear wall is used, the side hole can be easily punched through as needed to connect the side hole with the through hole.

[0036] The side formwork 6 is also provided with a plurality of steel bar holes, through which the steel bars of the steel bar frame of the hollow shear wall can extend, so as to reserve steel bars for binding with structures such as vertical beams outside the hollow shear wall.

[0037] In order to facilitate the demolding of the side form 6, a number of demolding screw holes are provided on the side form 6, and demolding screws are provided in the demolding screw holes. Before pouring, the demolding screws are rotated so that their ends are flush with the inner end faces of the side form 6. When demolding, the demolding screws are rotated, and the demolding screws press against the side end faces of the hollow shear wall, thereby separating the side form 6 from the hollow shear wall.

[0038] After the hollow shear wall is poured with concrete, it takes some time for the concrete to solidify. In order to improve production efficiency, please refer to Figure 1 In one-step implementation, the vertical forming device is set up as two groups, and the two groups of devices share the base 1 and the reference mold 2. The two groups of devices are used complementary to each other. When the pouring of each forming area on one side of the reference mold 2 is completed and the concrete is waiting to solidify and form, production can be carried out on the other side of the reference mold 2, which effectively improves production efficiency while avoiding more space occupation.

[0039] See also Figures 1-6 The process for producing a hollow shear wall using the vertical forming device includes the following steps: Step 1, according to the width of the hollow shear wall to be produced, adjust the spacing between the two side molds 6 of each forming area, according to the height of the hollow shear wall to be produced, adjust the number of cushion layers on the bottom mold 5, so that the height difference between the upper end surface of the uppermost cushion layer and the upper edge of the forming area is consistent with the height of the hollow shear wall to be produced, and finally make the specifications of the casting forming cavity consistent with the specifications of the hollow shear wall to be produced; set a steel bar frame in each forming area, lead out steel bars from the steel bar frame toward the side of the side mold 6, and each steel bar extends from each steel bar hole on the corresponding side mold 6, and the driving mechanism 8 drives the side mold 3 along the guide rail to approach the reference mold 2, and the side mold 3, reference mold 2 and each intermediate mold 4 cooperate to fix the bottom mold 5 and side mold 6 of each forming area, and use the locking mechanism 12 to tighten the side mold 3, tighten the side mold 3 and each intermediate mold 4, insert the middle hole mold 7 into each positioning hole on the bottom mold 5, and then use the fixing mechanism 11 to fix the corresponding middle hole mold 7.

[0040] Step 2: pouring concrete into each forming casting cavity.

[0041] Step three: Before the concrete in each forming casting cavity is completely solidified and shaped, use a groove mold to press down on the upper end surface of the formed hollow shear wall to form a groove on the side of each center hole mold 7. The groove mold is preferably a round rod along the distribution direction of the two side molds 6. Each groove extends and distributes along the distribution direction of the two side molds 6 on the upper end surface of the hollow shear wall. Each groove forms a connecting groove, which passes through the two end surfaces of the hollow shear wall along the distribution direction of the two side molds 6 and is connected to each through hole.

[0042] Step 4: After the concrete in each molding cavity solidifies and takes shape, the locking telescopic parts extend, and the locking mechanism 12 loosens the side mold 3, disconnecting the side mold 3 from the adjacent first intermediate mold 4. The specific operation is to remove the connecting parts connecting the side mold 3 and the first intermediate mold 4 from the connecting groove 10, and the driving mechanism 8 drives the side mold 3 away from the intermediate molds 4 and exposes the hollow shear wall formed in the first molding area. The hollow shear wall is removed manually or by a crane. At this time, the first hollow shear wall has been removed. When taking the second hollow shear wall, the driving mechanism 8 drives the side mold 3 close to the intermediate mold 4, connects the side mold 3 to the adjacent first intermediate mold 4 by using the connecting parts, disconnects the first two intermediate molds 4 adjacent to the side mold 3, and drives the side mold 3 and an intermediate mold 4 connected thereto away from the remaining intermediate molds 4, exposing the hollow shear wall formed in the second molding area, and after the hollow shear wall is taken out. When taking the third hollow shear wall, the driving mechanism 8 drives the side mold 3 and an intermediate mold 4 close to the remaining intermediate molds 4, connects the first two intermediate molds 4 adjacent to the side mold 3, and disconnects the second intermediate mold 4 adjacent to the side mold 3 from the third intermediate mold 4. The driving mechanism 8 drives the side mold 3 and the two intermediate molds 4 away from the remaining intermediate molds 4 and exposes the hollow shear wall formed in the second forming area, takes out the hollow shear wall, and repeats the above operation until the hollow shear walls formed in each forming area are taken out.

[0043] In step 4, the first intermediate mold 4 refers to the first intermediate mold 4 along the guide rail from the side mold 3 to the reference mold 2, the first forming area refers to the first forming area along the guide rail from the side mold 3 to the reference mold 2, and both the intermediate mold 4 and the forming area are the ones closest to the side mold 3. The second intermediate mold 4 refers to the second intermediate mold 4 along the guide rail from the side mold 3 to the reference mold 2, the second forming area refers to the second forming area along the guide rail from the side mold 3 to the reference mold 2, the third intermediate mold 4 refers to the third intermediate mold 4 along the guide rail from the side mold 3 to the reference mold 2, and so on. Before taking each hollow shear wall, it is necessary to operate each fixing mechanism 11 corresponding to the forming area so that the pressure plate of each fixing mechanism 11 is in the avoidance position.

[0044] Step five, when the hollow shear wall is taken out in step four, the hollow shear wall, side formwork 3 and center hole formwork 7 are taken out together. Step five needs to separate the taken out hollow shear walls from the side formwork 6 and the center hole formwork 7. When separating the center hole formwork 7, the hollow shear wall can be placed in the limit frame for fixation, and the center hole formwork 7 can be pushed out or pulled out; when separating the side formwork 6, the demolding screws on each side formwork 6 are rotated to separate the side formwork 6 from the side end face of the hollow shear wall. Finally, the side formwork 6 can be separated, and the required hollow shear wall is finally obtained.

[0045] Example 2 The hollow shear wall includes a wall panel 13, which is made by the process of Example 1. The wall panel 13 is provided with a through hole formed by each center hole mold 7. The through hole is vertically arranged and passes through the upper end face and the lower end face of the wall panel 13. The upper end face of the wall panel 13 is provided with a connecting groove. The connecting groove passes through the left end face and the right end face of the wall panel 13 along the left and right directions of the wall panel 13, and the connecting groove is connected to each through hole; steel bars extend from the left and right end faces of the wall panel 13, and at least one connecting hole is vertically distributed on the left and right end faces of the wall panel 13. The connecting hole is formed by the side hole punch of the inner end face of the side mold 6. The connecting hole corresponds to the position of the adjacent through hole. The connecting hole is not connected with the adjacent through hole and can be opened more easily in actual use.

[0046] The side hole punch can be set to a quadrangular pyramid shape, so that the formed connecting hole is a quadrangular pyramid-shaped expanded hole. Of course, the side hole punch can also be set to other forms of prisms or cones to form expanded holes of corresponding shapes. This setting facilitates the separation of the side mold and the wall panel.

[0047] When the shear wall of this embodiment is installed and used, the wall panel 13 is placed in the middle frame surrounded by the steel frames of the two horizontal beams and the steel frames of the two vertical beams, and the steel structure is inserted into the through hole. The steel structure is connected to the steel frames of the upper and lower horizontal beams, and the steel members extending from the left and right end faces of the wall panel 13 are respectively connected to the steel frames of the two vertical beams. When pouring concrete, the horizontal beams, vertical beams and concrete in the through hole are connected and form a whole. The wall panel 13, the horizontal beams and the vertical beams form a stable wall structure.

[0048] The connecting groove provided on the upper end surface of the wall panel 13 can connect two adjacent through holes. The concrete of the two adjacent through holes is connected through the connecting groove and can form a whole with the concrete of the upper beam. The connecting groove is preferably a U-shaped groove with an arc-shaped inner wall. Since the connecting groove at the top of the wall panel 13 is concave, the gap between the connecting groove and the concrete is in the form of a concave arc. It is not easy for external rainwater to pass through the gap in the form of the concave arc and cross the connecting groove into the room, thereby achieving a waterproof effect.

[0049] During the production of Example 1, a lifting ring can be inserted into the concrete so that the formed wall panel 13 has a lifting ring, which is convenient for lifting during production and use.

[0050] In some embodiments, the hollow shear wall includes at least two wall panels 13, with multiple wall panels 13 used in combination. Taking two wall panels 13 as an example, the two wall panels 13 are stacked vertically, with the through holes in the upper wall corresponding to and communicating with the through holes in the lower wall. During use, the two wall panels are combined and placed within a central frame formed by the steel bars of the two horizontal beams and the steel bars of the two vertical beams. The steel bars pass through the through holes in the two wall panels 13 and connect to the steel bars of the upper and lower horizontal beams. The steel bars extending from the left and right end faces of each wall panel 13 are connected to the steel bars of the two vertical beams, and then cast. The junction of the two wall panels 13 is connected and waterproofed through a connecting groove in the lower wall.

[0051] In this embodiment, the hollow shear wall includes at least two wall panels 13. The wall panels 13 are assembled and combined during use and cast with horizontal beams and vertical beams to form a wall. During transportation, the wall panels 13 can be separated, which can effectively solve the transportation problems caused by road width and height restrictions. Moreover, since the wall height is lower than the original wall, the load of the crane can be reduced during construction.
