Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a concrete twist block mold. Background Art

[0002] Concrete twist blocks are widely used in construction projects as mold forming components. Among them, concrete twist blocks are commonly used as wave-breaking buffer components on the seashore. They are large in size and heavy in weight, which requires the molds used to prepare them to be large in size, resulting in a large mold weight. This large mold faces the following problems during use:

[0003] 1. Inconvenient to move and potential safety hazards: Due to their large size and weight, large molds cannot be quickly moved by forklift like small molds. On the construction site, to move large molds within different working areas over short distances, it usually requires multiple people to push and pull, which is time-consuming and labor-intensive, and there is a risk of overturning, damage, and injury.

[0004] 2. Incomplete demoulding and low efficiency: The existing demoulding uses hydraulic jacks, but due to the single thrust direction of the jack and the large weight and volume of the large mold, the jack cannot separate the multiple connections between the mold shell and the prefabricated block components at the same time. In addition, the installation and operation of the jack are also relatively troublesome, and the efficiency is still low.

[0005] 3. Insufficient structural strength: Due to the large size of large molds and the large bonding surface area between them and the prefabricated block components, when the demoulding force is large during demoulding, it is easy to cause the mold to deform or break during use, shortening the service life of the mold.

[0006] The above problems lead to low production efficiency of concrete twist blocks, great construction safety hazards, short mold service life and other problems. Therefore, there is an urgent need for a concrete twist block mold that is easy to move and safe and reliable, has thorough and efficient demoulding, high structural strength and long service life to meet the needs of modern construction. Utility Model Content

[0007] The purpose of the utility model is to overcome at least one defect in the prior art and provide a concrete twist block mold which is easy to move and safe and reliable, has thorough demoulding and high efficiency, has high structural strength and long service life.

[0008] In order to solve the above problems, the utility model provides a concrete twist block mold, including two symmetrically arranged half mold shells, the two half mold shells cover each other to form a casting cavity, and the outer walls of the half mold shells are supported with a universal wheel group and a lifting component for controlling the universal wheel group to be lifted off the ground.

[0009] Compared with the prior art, the benefits of the present invention are as follows: the concrete twist block mold of the present invention effectively solves the problems of heavy weight and inconvenient movement of traditional molds through the universal wheel group and the lifting component, so that the mold can be easily and conveniently moved horizontally, and the lifting component controls the lifting of the universal wheel group so that the bottom of the mold contacts the ground for stable support, which not only improves the construction efficiency, but also ensures the safety and stability of the mold during movement, avoids the safety hazard of traditional molds being easily pushed or pulled down, and brings great convenience to construction operations.

[0010] As an improvement, the universal wheel group includes a first support frame, a second support frame, a first universal wheel and a second universal wheel. The first support frame is detachably connected to the middle of the outer wall of the half mold shell, the first universal wheel is supported by the bottom of the first support frame for vertical movement, the second support frame is provided on both sides of the outer wall of the half mold shell, and the second universal wheel is supported by the bottom of the second support frame for vertical movement. This structure effectively solves the problems of the inconvenience of moving the traditional concrete twist block mold and the low mold opening safety by providing the first support frame and the second support frame in conjunction with the universal wheel, thereby improving the construction efficiency and production safety. Among them, the design of the detachable connection of the first support frame plays a key role in improving the mold safety and extending the mold service life, because during the mold opening process, the half mold shell will tilt, and the detachable first support frame can avoid being squeezed and damaged, thereby ensuring the normal mold opening of the mold and extending the mold service life.

[0011] As an improvement, the lifting assembly includes a first height adjustment screw and a second height adjustment screw. The first height adjustment screw is threadedly connected to the first support frame and fixedly connected to the base of the first universal wheel. The second height adjustment screw is threadedly connected to the second support frame and fixedly connected to the base of the second universal wheel. This technical solution adjusts the lifting of the universal wheel by rotating the thread of the height adjustment screw on the support frame. Compared with other structures for controlling the lifting of the universal wheel group, this lifting assembly has a simple structure, convenient operation, lower cost, and is easier to achieve mold height adjustment, thereby improving construction efficiency and production safety.

[0012] As an improvement, the first height adjustment screw and the second height adjustment screw are provided with handles, and the handles are provided with crowbar insertion holes, which axially penetrate the two end faces of the handles. This design cleverly combines the handle with the height adjustment screw and provides a crowbar insertion hole, so that the operator can control the rotation of the height adjustment screw by turning the handle, thereby realizing the lifting and lowering adjustment of the universal wheel set. This simple design not only improves the convenience and efficiency of operation, but also reduces the difficulty of operation. Even when the mold is heavy, the operator can insert the crowbar to extend the force arm, so that the operator can turn the adjustment screw more easily, overcoming the problem that the adjustment screw is difficult to turn, reducing the labor intensity of workers, making the positioning and movement of the mold more flexible, and effectively improving the construction efficiency.

[0013] As an improvement, multiple fixing holes are provided along the closing line of the half mold shells, and the fixing holes are used to install bolt and nut assemblies. This design enhances the mold connection strength, ensures that the two half mold shells are firmly closed, and will not be spread apart by a large amount of concrete in the casting cavity, effectively prevents the mold shells from separating during the casting process, improves construction safety, and at the same time ensures the quality of the cast concrete and improves the quality of the project.

[0014] As an improvement, the outer wall of the half mold shell is provided with multiple ribs staggered in longitude and latitude, and the upper surfaces of the outer walls of the half mold shell are provided with placement grooves, which are formed by the reinforcement ribs. This design not only enhances the strength of the mold shell itself and prevents it from deforming under the action of external forces, but also cleverly utilizes the reinforcement rib structure of the mold shell itself to form the placement groove, providing a storage location for the bolts and nuts removed from the mold shell when opening the mold to prevent loss. At the same time, the placement groove is set close to the cover line of the two half mold shells to ensure more convenient use; through this structural design, the mold structure is simplified, the operating efficiency is improved, and the loss of bolts and nuts is avoided, the construction cost is reduced, and the overall efficiency of the construction is improved.

[0015] As an improvement, a jack hole connected to the casting cavity is provided in the middle of the outer wall of the half mold shell, and a cover plate is hinged on the outer wall of the half mold shell, and a plug part is provided on the cover plate for controlling the opening and closing of the jack hole. The design of the jack hole facilitates the use of a jack from the outside of the mold to extend into the casting cavity inside the mold, and to push the concrete twist block in the casting cavity, thereby realizing the separation of the mold shell and the concrete twist block. The hinged design of the cover plate facilitates the opening and closing of the cover plate. At the same time, the setting of the plug part ensures the sealing of the mold, prevents external debris from entering the casting cavity and the concrete slurry in the casting cavity from overflowing, ensures the cleanliness and safety of the mold, and improves the overall use efficiency and life of the mold.

[0016] As an improvement, a jack fixing frame is arranged on the outer wall of the half mold shell, the jack fixing frame is located outside the jack hole, and includes a jack mounting seat, a channel steel top pull arm and a pair of pull rods. The jack mounting seat is fixedly arranged on the channel steel top pull arm, and the two ends of the channel steel top pull arm are arranged on the outer wall of the half mold shell through a pair of pull rods. This design cleverly combines the jack hole with the cover plate, which not only ensures the realization of mold opening, but also ensures the sealing of the mold to prevent the concrete slurry from overflowing. The design of the jack hole facilitates the use of a jack outside the outer mold to extend into the casting cavity inside the mold and push the concrete twist block in the casting cavity, thereby realizing the separation of the mold shell and the concrete twist block. The hinged design of the cover plate facilitates the opening and closing of the cover plate. At the same time, the setting of the plug can effectively control the opening and closing of the jack hole, prevent external debris from entering the casting cavity and the concrete slurry in the casting cavity from overflowing, ensure the cleanliness and safety of the mold, and improve the overall use efficiency and life of the mold.

[0017] As an improvement, support blocks are fixed on both sides of the outer wall of the half mold shell, and the support blocks are arranged close to the cover line of the half mold shell and form a crowbar slot between the two half mold shells. In this design, when demoulding, if the prefabricated block after casting is too large and it is still impossible to separate it from the mold shell by the jack alone, you can insert a crowbar into the crowbar slot, use the crowbar to pry open the mold shell, and then insert the crowbar into the junction of the mold shell and the prefabricated block to separate the prefabricated block from the mold shell. Usually, multiple crowbar slots can be set to increase the prying points, facilitate operation, and improve demoulding efficiency, ensuring the smooth demoulding process of the prefabricated block. This design provides a more flexible operation method for demoulding the prefabricated block, and even large-sized prefabricated blocks can be easily demoulded, which improves production efficiency. At the same time, it increases the scope of application of the mold and realizes more efficient prefabricated block production.

[0018] As an improvement, the reinforcing rib support is fixed between the half mold shell and the support block. This design is mainly to increase the structural strength of the prying point of the crowbar to prevent the support block from deforming or breaking during the prying process, thereby improving the safety during the prying process and extending the service life of the mold.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 and Figure 3 As shown, in the utility model, the concrete twist block mold includes two symmetrically arranged half-mold shells 1, which cover each other to form a casting cavity 2. A universal wheel set 3 and a lifting component 4 for controlling the universal wheel set 3 to be lifted off the ground are supported on the outer wall of the half-mold shells 1.

[0027] The concrete twist block mold of the utility model effectively solves the problems of heavy deadweight and inconvenient movement of traditional molds through the universal wheel group 3 and the lifting component 4, so that the mold can be easily and conveniently moved horizontally, and the lifting component 4 controls the universal wheel group 3 to be lifted so that the bottom of the mold contacts the ground for stable support, which not only improves the construction efficiency, but also ensures the safety and stability of the mold during movement, avoids the safety hazard of traditional molds being easily pushed or pulled down, and brings great convenience to construction operations.

[0028] like Figure 1 and Figure 3 As shown, the universal wheel group 3 includes a first support frame 11, a second support frame 12, a first universal wheel 31 and a second universal wheel 32. The first support frame 11 is detachably connected to the middle of the outer wall of the half-mold 1. The first universal wheel 31 is supported and arranged at the bottom of the first support frame 11 for vertical movement. The second support frame 12 is arranged on both sides of the outer wall of the half-mold 1. The second universal wheel 32 is supported and arranged at the bottom of the second support frame 12 for vertical movement. In order to realize the detachable connection between the half-mold 1 and the first support frame 11, a connecting block is fixed on the outer wall of the half-mold 1, and corresponding mounting holes are opened on the connecting block and the first support frame 11. The first support frame 11 and the half-mold 1 can be detachably connected together by using a bolt and nut assembly in the two mounting holes. In addition, any one of the two mounting holes is set as a threaded hole, and the detachable connection between the first support frame 11 and the half-mold 1 can also be realized by the threaded connection of the bolt and the threaded hole. This structure effectively solves the problems of the inconvenient movement of the traditional concrete twist block mold and the low mold opening safety by setting the first support frame 11 and the second support frame 12 in conjunction with universal wheels, thereby improving the construction efficiency and production safety. Among them, the detachable connection design of the first support frame 11 plays a key role in improving the mold safety and extending the service life of the mold. Because during the mold opening process, the half mold shell 1 will tilt, and the detachable first support frame 11 can avoid being squeezed and damaged, thereby ensuring the normal mold opening and extending the service life of the mold.

[0029] like Figure 1 and Figure 3As shown, the lifting assembly 4 includes a first height adjustment screw 41 and a second height adjustment screw 42. The first height adjustment screw 41 is threadedly connected to the first support frame 11 and fixedly connected to the base of the first universal wheel 31. The second height adjustment screw 42 is threadedly connected to the second support frame 12 and fixedly connected to the base of the second universal wheel 32. This technical solution adjusts the lifting of the universal wheel by rotating the thread of the height adjustment screw on the support frame. Compared with other structures for controlling the lifting of the universal wheel assembly 3, the lifting assembly 4 has a simple structure, convenient operation, lower cost, and is easier to achieve mold height adjustment, thereby improving construction efficiency and production safety.

[0030] like Figure 1 and Figure 3 As shown, the first height adjustment screw 41 and the second height adjustment screw 42 are provided with a handle 5, respectively, and the handle 5 is provided with a crowbar insertion hole 50, and the crowbar insertion hole 50 axially penetrates the two end surfaces of the handle 5. This design cleverly combines the handle 5 with the height adjustment screw and provides a crowbar insertion hole, so that the operator can control the rotation of the height adjustment screw by turning the handle 5, thereby realizing the lifting and lowering adjustment of the universal wheel set 3. This simple design not only improves the convenience and efficiency of operation, but also reduces the difficulty of operation. Even when the mold is heavy, the operator can more easily turn the adjustment screw by inserting a crowbar to extend the lever arm, thus overcoming the problem that the adjustment screw is difficult to turn, reducing the labor intensity of workers, making the positioning and movement of the mold more flexible, and effectively improving the construction efficiency.

[0031] like Figure 1 and Figure 3 As shown, a plurality of fixing holes 10 are provided on the half-mold 1 along its closing line, and the fixing holes 10 are used to install bolt and nut assemblies. This design enhances the mold connection strength, ensures that the two half-molds 1 are firmly closed, and will not be spread apart by a large amount of concrete in the casting cavity 2, effectively prevents the molds from separating during the casting process, improves construction safety, and at the same time ensures the quality of the cast concrete and improves the quality of the project.

[0032] like Figure 1 and Figure 3 As shown, the outer wall of the half mold shell 1 is provided with multiple crisscrossed reinforcement ribs 13, and the upper surfaces of both sides of the outer wall of the half mold shell 1 are provided with placement grooves 14, which are formed by the reinforcement ribs 13. This design not only enhances the strength of the mold shell itself to prevent it from being deformed under the action of external force, but also cleverly utilizes the reinforcement ribs 13 structure of the mold shell itself to form the placement grooves 14, providing a storage location for the bolts and nuts removed from the mold shell when opening the mold to prevent loss. At the same time, the placement grooves 14 are arranged close to the covering line of the two half mold shells 1 to ensure more convenience during use; through this structural design, the mold structure is simplified, the operating efficiency is improved, and the loss of bolts and nuts is avoided, the construction cost is reduced, and the overall efficiency of the construction is improved.

[0033] like Figure 3 and Figure 4 As shown, a jack hole 20 connected to the casting cavity 2 is provided in the middle of the outer wall of the half mold shell 1, and a cover plate 6 is hinged on the outer wall of the half mold shell 1, and the cover plate 6 has a plug 60 for controlling the opening and closing of the jack hole 20. The plug 60 is a rubber plug, and is usually designed to be a conical structure. In order to make the plug 60 more firmly close the jack hole 20, a nut is usually welded on the outer wall of the half mold shell 1, and a slot for plugging with the nut is provided on the cover plate 6. The slot is located on the opposite side of the hinged end of the cover plate 6. When the plug 60 closes the jack hole 20, a pin is inserted into the nut hole to limit the cover plate 6 from rotating and opening. The design of the jack hole 20 makes it convenient to use a jack from the outside of the mold to extend into the casting cavity 2 inside the mold and push the concrete twist block in the casting cavity 2, thereby realizing the separation of the mold shell and the concrete twist block. The hinged design of the cover plate 6 facilitates the opening and closing of the cover plate 6. At the same time, the setting of the plug 60 ensures the sealing of the mold, prevents external debris from entering the casting cavity 2 and the concrete slurry in the casting cavity 2 from overflowing, ensures the cleanliness and safety of the mold, and improves the overall use efficiency and life of the mold.

[0034] like Figure 3 and Figure 4 As shown, a jack fixing frame 7 is arranged on the outer wall of the half mold shell 1. The jack fixing frame 7 is located on the outside of the jack hole 20 and includes a jack mounting seat 71, a channel steel top pulling arm 72 and a pair of pulling rods 73. The jack mounting seat 71 is fixed on the channel steel top pulling arm 72. The two ends of the channel steel top pulling arm 72 are arranged on the outer wall of the half mold shell 1 through a pair of pulling rods 73. This design cleverly combines the jack hole 20 with the cover plate 6, which not only ensures the realization of mold opening, but also ensures the sealing of the mold to prevent concrete slurry from overflowing. The design of the jack hole 20 facilitates the use of a jack outside the outer mold to extend into the casting cavity 2 inside the mold and push the concrete twist block in the casting cavity 2, thereby realizing the separation of the mold shell and the concrete twist block. The hinged design of the cover plate 6 facilitates the opening and closing of the cover plate 6. At the same time, the setting of the plug 60 can effectively control the opening and closing of the jack hole 20, prevent external debris from entering the casting cavity 2 and the concrete slurry in the casting cavity 2 from overflowing, ensure the cleanliness and safety of the mold, and improve the overall use efficiency and life of the mold.

[0035] like Figure 1 and Figure 2As shown, support blocks 8 are fixedly provided on both sides of the outer wall of the half mold shell 1, and the support blocks 8 are arranged close to the cover line of the half mold shell 1 and form a crowbar slot 80 between the two half mold shells 1. In this design, when demoulding, if the prefabricated block after casting is too large and it is still impossible to separate it from the mold shell by the jack alone, a crowbar can be inserted into the crowbar slot 80, and the mold shell can be pried open with the crowbar, and then the crowbar can be inserted into the junction of the mold shell and the prefabricated block to separate the prefabricated block from the mold shell. Usually, multiple crowbar slots 80 can be provided to increase the prying points, facilitate operation, and improve demoulding efficiency, ensuring the smooth demoulding process of the prefabricated block. This design provides a more flexible operation method for demoulding the prefabricated block, and even large-sized prefabricated blocks can be easily demoulded, which improves production efficiency, while increasing the scope of application of the mold and achieving more efficient prefabricated block production.

[0036] like Figure 1 and Figure 2 As shown, the reinforcing rib 13 is supported and fixed between the half mold shell 1 and the support block 8. This design is mainly to increase the structural strength of the prying point of the crowbar to prevent the support block 8 from deforming or breaking during the prying process, thereby improving the safety during the prying process and extending the service life of the mold.
