The side mold is provided on the base and moves along the guide rail. The locking mechanism is connected to the side mold. At least one intermediate mold is provided on the base between the side mold and the reference mold. Each intermediate mold cooperates with the guide rail and moves along the guide rail. The area between the side mold and the adjacent intermediate mold, the area between the reference mold and the adjacent intermediate mold, and the area between two adjacent intermediate molds are set as forming areas. A bottom mold is provided in each forming area. Two side molds are provided on the bottom mold. A central hole mold is provided between the two side molds in each forming area. A driving mechanism is also provided on the base. The driving mechanism is connected to the side mold and drives the side mold to move along the guide rail. The side mold is detachably connected to the adjacent intermediate mold and the area between two adjacent intermediate molds. The base mold, side mold, and several intermediate molds form multiple forming zones. Each forming zone, together with the bottom mold, middle hole mold, and side mold, forms a casting zone, which can realize the casting and forming of hollow shear walls. The detachable connection between the side mold and the adjacent intermediate mold, as well as between two adjacent intermediate molds, facilitates demolding after forming, reducing the difficulty of demolding and the labor intensity of personnel.

[0006] As an optional technical solution of this utility model, the side mold and each intermediate mold are provided with connecting seats. The connecting seats extend outside the molding area and are provided with connecting grooves. The connecting parts pass through the connecting grooves of two adjacent connecting seats and detachably connect the two connecting seats.

[0009] As an optional technical solution of this utility model, the drive mechanism is connected to the connecting seat of the side mold.

[0010] As an optional technical solution of this utility model, the bottom mold cooperates with the guide rail and moves along the guide rail. The bottom mold is provided with positioning holes corresponding to each middle hole mold. The bottom end of the middle hole mold is set into an inverted frustum shape and the middle hole mold is inserted into the positioning hole. The positioning holes on the bottom mold facilitate the positioning and fixing of the middle hole mold.

The fixing mechanism includes a vertical rod, a rotating arm, a locking plate and a pressure plate. The vertical rod and the locking plate are respectively set on both sides of the forming area. The rotating arm is connected to the vertical rod. A screw is provided on the rotating arm. The screw is set vertically and a pressure plate is provided at the bottom end of the screw. The rotating arm rotates relative to the vertical rod and drives the pressure plate to move back and forth between the pressing position and the clearance position. A locking groove is provided on the locking plate. When the pressure plate is in the pressing position, the rotating arm is embedded in the locking groove.

[0012] As an optional technical solution of this utility model, the distance between the two side molds on the bottom mold is adjustable, and the inner end face of each side mold is also provided with a side hole punch.

[0013] As an optional technical solution of this utility model, the side mold is provided with several demolding screw holes, and a demolding screw is screwed into the demolding screw holes.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] like Figures 1-3 As shown, a vertical forming device for a hollow shear wall includes a base 1, a reference mold 2, side molds 3, intermediate molds 4, a bottom mold 5, side molds 6, and a central hole mold 7. A guide rail is provided on the base 1. The reference mold 2 is fixedly mounted on the base 1 and located at the end of the guide rail. The side mold 3 is provided on the base 1, cooperating with the guide rail and capable of moving along the guide rail towards and away from the reference mold 2. A locking mechanism 21 is provided on the reference mold 2, connected to the side mold 3. During the casting and forming process of the hollow shear wall, the locking mechanism 21 tightly pulls the side mold 3, locking the side mold 3 and each intermediate mold 4, preventing tilting or movement of components such as the side mold 3 and intermediate mold 4 due to concrete impact or concrete setting, thereby ensuring the quality of the wall panel.

[0020] The clamping mechanism 21 is installed on the side end face of the reference mold 2 that is not used as the forming end face. One or more clamping mechanisms 21 are provided on each of the two opposite side end faces of the reference mold 2. The clamping mechanism 21 includes a clamping telescopic cylinder and a clamping arm. The clamping telescopic cylinder is connected to the reference mold 2 and rotates laterally relative to the reference mold 2. The telescopic part of the clamping telescopic cylinder is hinged to the clamping arm. The clamping arm is in the form of multiple rod segments that are sequentially hinged. The clamping arm is hinged to the side mold 3.

[0021] Please see Figure 1 At least one intermediate mold 4 is provided 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. Figure 1This is an example when there are two or more intermediate molds 4. When there is one intermediate mold 4, the area between the intermediate mold 4 and the side mold 3, and the area between the intermediate mold 4 and the reference mold 2 are forming areas. When there are two or more intermediate molds 4, the area between the side mold 3 and the adjacent intermediate mold 4, the area between the reference mold 2 and the adjacent intermediate mold 4, and the area between two adjacent intermediate molds 4 are forming areas. Each forming area is provided with a bottom mold 5, and two side molds 6 are provided on the bottom mold 5. A central hole mold 7 is also provided between the two side molds 6 in each forming area. When the bottom mold 5 is connected to the two inner walls of the forming area, the space enclosed 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 central hole mold 7, and the inner end face of the forming area is the forming and casting area. The required hollow shear wall can be formed by pouring concrete into the casting and forming area. The bottom mold 5 and the side mold 6 are of equal width. When forming the molding and casting area, the mold locking mechanism 21 cooperates with the drive mechanism to lock the positions of the side mold 3, the middle mold 4 and other components. The side mold 6 and the bottom mold 5 both abut against the inner end faces of the two sides of the molding area.

[0022] The side mold 3 is detachably connected to the adjacent intermediate mold 4, and between two adjacent intermediate molds 4. A drive mechanism 11 is provided on the base 1. The actuating part of the drive mechanism 11 is connected to the side mold 3. The drive mechanism 11 drives the side mold 3, or the side mold 3 and a specified number of intermediate molds 4, to move along the guide rail, thereby facilitating mold closing and demolding. Please refer to [link / reference]. Figure 1 When demolding the hollow shear wall after molding, firstly, the connection between the side mold 3 and the adjacent intermediate mold 4 is disconnected. The driving mechanism 11 moves the side mold 3 away from the first intermediate mold 4, exposing the hollow shear wall in the first molding area. After removing the hollow shear wall, the driving mechanism 11 moves the side mold 3 closer to the first intermediate mold 4, connecting the side mold 3 to the first intermediate mold 4. Then, the connection between the first intermediate mold 4 and the second intermediate mold 4 is disconnected. The driving mechanism 11 moves the side mold 3 and the first intermediate mold 4 away from the second intermediate mold 4, exposing the hollow shear wall in the second molding area. After removing the hollow shear wall, the driving mechanism 11 moves the side mold 3 and the first intermediate mold 4 closer to the second intermediate mold 4, connecting the first intermediate mold 4 to the second intermediate mold 4 and disconnecting the connection between the second intermediate mold 4 and the third intermediate mold 4. The above operation is repeated to remove the hollow shear walls from each molding area, effectively reducing the labor intensity of personnel during demolding and improving demolding efficiency.

[0023] The drive mechanism 11 is preferably a telescopic component. The drive mechanism 11 is set on the base 1. Since the locking arm of the locking mechanism 21 is a multi-segment rod that is sequentially hinged, when the locking mechanism 21 drives the side mold 2 to move, the side mold 2 drives the locking arm to change state, which will not affect the drive mechanism 11 to drive the side mold 2 to move. When pouring concrete into each forming area, the locking mechanism 21 and the drive mechanism 11 are used to lock the position of the side mold 2 and each intermediate mold 4.

[0024] To ensure sufficient connection strength between the side mold 3 and the adjacent intermediate mold 4, and between two adjacent intermediate molds 4, during demolding, the two ends of the side mold 3 are detachably connected to the two ends of the adjacent intermediate mold 4, and the two ends of the intermediate mold 4 are detachably connected to the two ends of the adjacent intermediate mold 4.

[0025] To further facilitate mold disassembly, connecting seats 8 are provided on both sides of the side mold 3 and each intermediate mold 4. The connecting seats 8 extend outside the molding area and are provided with connecting grooves. Adjacent connecting seats 8 are detachably connected by connecting members. The connecting members pass through the corresponding connecting grooves of the two adjacent connecting seats 8 and connect the two connecting seats 8. The connection between the two connecting seats 8 can be broken by disconnecting the connecting members from one or two connecting seats 8.

[0026] To further facilitate the connection and disconnection of adjacent connecting seats 8, a connecting groove is provided on the side of the connecting seat 8. The connecting groove is a downwardly extending oblique groove. The connector can be configured with limiting parts at both ends, and the limiting parts cannot pass through the limiting parts of the connecting groove. As an example, the connector includes a screw and two nuts. The screw passes through the corresponding connecting grooves of the two adjacent connecting seats 8, and the two nuts are screwed onto the connector and serve as limiting parts. The connector can also be configured with limiting parts formed by bending at both ends. When connecting the two adjacent connecting seats 8, the connector is simultaneously embedded into the two connecting grooves, and the two connecting grooves are located between the two limiting parts. When disconnecting the two adjacent connecting seats 8, the connector can be taken out along the connecting groove. The downwardly extending oblique shape of the connecting groove not only facilitates the installation and removal of the connector, but also prevents the connector from accidentally falling off.

[0027] At least two connecting slots are provided on the side of the connecting seat 8, and adjacent connecting seats 8 are connected by at least two connecting pieces, thereby improving the connection effect between the side mold 3 and the adjacent intermediate mold 4, and between two adjacent intermediate molds 4.

[0028] Please see Figure 3The bottom mold 5 is independent of the side mold 3 and the intermediate 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, side mold 3, and intermediate mold 4 are all equipped with pulley mechanisms, which cooperate with the guide rail. Specifically, the guide rail is a T-shaped or I-shaped rail. The pulley mechanism includes a pulley seat, an upper pulley, and a lower pulley. A through groove is formed in the pulley seat, penetrating the bottom surface of the pulley seat and two opposite side end faces. The upper pulley is located in the through groove, and lower pulleys are located on opposite sides of the inner wall 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 rail surface, and the two lower pulleys are located on both sides of the guide rail and cooperate with the two side end faces of the guide rail or the lower end face of the upper rail surface. The cooperation of 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, achieving movable installation of the bottom mold 5, side mold 3, and intermediate mold 4. Furthermore, a limiting groove is provided on the outer wheel surface of the upper pulley along the circumference. The top of the guide rail is embedded in the limiting groove, and the upper rail surface cooperates with the part of the upper pulley in the limiting groove, further limiting the direction of movement of the pulley seat along the guide rail.

[0029] The bottom mold 5 is provided with positioning holes 51. There are one or more positioning holes 51, depending on the number of central holes to be produced in the hollow shear wall. Each central hole mold 7 corresponds to a positioning hole 51. The bottom end of the central hole mold 7 is inserted into the positioning hole 51 to realize the positioning and fixing of the central hole mold 7. The bottom end of the central hole mold 7 is set as an inverted frustum or an inverted cone tip to facilitate the quick insertion of the central hole mold 7 into the positioning hole 51.

[0030] Above the forming area, corresponding to the positions of each intermediate mold 7, a fixing mechanism 71 is provided. The fixing mechanism 71 is used to fix the intermediate mold 7 onto the bottom mold 5 during casting, thereby fixing the intermediate mold 7 and preventing it from shifting due to the impact of concrete during the casting process. When the fixing mechanism 71 is in the forming area between the side mold 3 and the adjacent intermediate mold 4, the fixing mechanism 71 is installed through the side mold 3 and the intermediate mold 4. When the fixing mechanism 71 is in the forming area between the reference mold 2 and the adjacent intermediate mold 4, the fixing mechanism 71 is installed through the reference mold 2 and the intermediate mold 4. When the fixing mechanism 71 is in the forming area between two adjacent intermediate molds 4, the fixing mechanism 71 is installed through the two intermediate molds 4.

[0031] For details, please refer to Figures 1-3The fixing mechanism 71 includes a vertical rod, a rotating arm, a locking plate, and a pressure plate. The vertical rod and the locking plate are located on opposite sides of the forming area. A rotating arm is mounted on the vertical rod, allowing it to rotate horizontally relative to the vertical rod. The rotating arm has a screw hole with a screw rod installed inside. The screw rod is vertically positioned, and a pressure plate is located at its bottom end. The pressure plate is rotatably connected to the screw rod, allowing the pressure plate to rotate relative to the screw rod and adjust its angle. Rotation of the screw rod can raise and lower the pressure plate. The rotating arm rotates relative to the vertical rod, causing the pressure plate to reciprocate between a pressing position and a clearance position. The locking plate has a locking groove. The rotating arm... When the moving pressure plate moves to the clamping position, the rotating arm is embedded in the locking groove, and the pressure plate is located above the corresponding central hole mold 7. At this time, rotating the screw to adjust the height of the pressure plate can press the pressure plate onto the central hole mold 7 and press the central hole mold 7 into the fixing hole to fix the central hole mold 7. After the hollow shear wall in the forming area is formed, rotating the screw drives the pressure plate to rise. After the pressure plate is separated from the central hole mold 7, rotating the rotating arm drives the pressure plate to move to the clearance position. At this time, the pressure plate is located on the side of the forming area, making room above the forming area, which facilitates the removal of the central hole mold 7 from above, and also facilitates the demolding and removal of the hollow shear wall.

[0032] To accommodate the production of various types of hollow shear walls, the spacing between the two side molds 6 on each bottom mold 5 is adjustable. As a specific example, the bottom mold 5 and / or the intermediate mold 4 have multiple mounting holes along their long sides. The side molds 6 are connected to the bottom mold 5 and the intermediate mold 4 via bolts or other components. The position of the side molds 6 can be adjusted on the bottom mold 5, thereby adjusting the spacing between the two side molds 6. As another specific example, the bottom mold 5 has adjusting bases at both ends, with screws mounted on these bases. The screws are rotatable along the long side of the bottom mold 5, and their ends are rotatably connected to the side molds 6. Rotating the screws allows adjustment of the position of the side molds 6 along the long side of the bottom mold 5, thereby adjusting the spacing between the two side molds 6.

[0033] The bottom mold 5 is provided with a pad, and the pad is also reserved with holes corresponding to each positioning hole 51. When it is necessary to adjust the height of the hollow shear wall, a certain number of pads can be used.

[0034] The inner end face of the side mold 6 is also provided with a side hole punch. The side hole punch is used to form the side hole of the hollow shear wall during casting. The side hole punch is preferably a quadrangular frustum or other frustum or cone shape, so that the formed side hole is an flared hole, and it is easy to demold the side mold 6.

[0035] To facilitate the removal of the side formwork 6, several removal screw holes are provided on the side formwork 6, and removal screws are installed in the removal screw holes. Before pouring, the removal screws are rotated so that their ends are flush with the inner end face of the side formwork 6. During removal, each removal screw is rotated, and the removal screws press against the side end face of the hollow shear wall, thereby removing the side formwork 6 from the hollow shear wall and realizing the rapid removal of the side formwork 6.

[0036] Since the concrete needs time to set after the hollow shear wall is poured, in order to improve production efficiency, in a further embodiment, the vertical forming device is set into two sets. The two sets of devices share the base 1 and the reference mold 2. The two sets of devices are used in a complementary manner. When the forming areas on one side of the reference mold 2 are poured and waiting for the concrete to set, production can be carried out on the other side of the reference mold 2, which effectively improves production efficiency and avoids more space occupation.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
