Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a building concrete mold. Background Technology

[0002] With the rapid development of prefabricated construction, the large-scale production of precast concrete components (such as wall panels, stairs, beams, and columns) has become a core control point for construction progress. As a key carrier for component forming, the efficiency of mold assembly and disassembly and the forming accuracy directly affect the component qualification rate and production line capacity.

[0003] However, the existing mainstream mold systems are very cumbersome in the mold assembly and disassembly process, resulting in low molding efficiency and increasing the workload of operators. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a building concrete mold to solve the problems mentioned above in the background art.

[0005] A building concrete mold includes a base plate, model parts symmetrically arranged on both sides of the base plate and rotatable around the sides of the base plate, and limiting members detachably installed on the top surfaces of both ends of the base plate. The model parts have a limited state and an open state. In the limited state, the two model parts, the two limiting members, and the base plate together form a mold cavity. In the open state, the model parts separate from the limiting members, thereby releasing the mold cavity. A limiting structure is detachably installed between the two model parts to lock the model parts in the limited state.

[0006] Compared to existing technologies, the advantages of this application are as follows: The vertical insertion and extraction action of the limiting structure enables instantaneous locking (limited state) or release (non-limited state) of the model component. This design completely eliminates the traditional progressive tightening process of bolts, reducing the time required for single-point locking and eliminating the need for auxiliary tools such as wrenches, thus reducing manual labor intensity. The rotation mechanism of the model component around the side of the base plate supports free adjustment of the angle from 0° (fully closed) to 90°-110° (demolding preparation position), giving the mold opening and closing action a very high degree of operational freedom. The modular design of the detachable limiting component eliminates the vibration and impact caused by traditional bolt disassembly, reducing the surface damage rate of concrete components. Combined with the rigid constraint mechanism of the limiting structure on the two model components, it solves the technical defect of easy loosening of rotatable molds.

[0007] Furthermore, the limiting structure includes a fixing plate respectively disposed on the side of the two model parts away from the base plate, a limiting through hole opened on the top of the fixing plate and penetrating both sides of the fixing plate, a fixing rod adapted to the limiting through hole, a fixing part connected to one end of the fixing rod, and a disassembly part detachably disposed on the other end of the fixing rod, so that the disassembly part cooperates with the fixing part to press the two fixing plates to achieve locking.

[0008] Furthermore, the disassembly part includes a plug-in block and a limiting block vertically fixed to the top of the plug-in block. The plug-in block and the limiting block form a T-shaped structure. The other end of the fixing rod is provided with a plug-in hole that is adapted to the plug-in block. When the plug-in block is inserted into the plug-in hole, the bottom of the plug-in block abuts against the fixing plate and the bottom of the limiting through hole, and the two ends of the limiting block abut against the fixing plate and the two ends of the limiting through hole, respectively.

[0009] Furthermore, the cross-sections of the plug block and the plug hole are rectangular.

[0010] Furthermore, multiple first rotating plates are spaced apart on both sides of the base plate, and each first rotating plate has a first through hole. Multiple second rotating plates are spaced apart on the side of the model piece closest to the base plate, and each second rotating plate has a second through hole. The rotating rod passes through all the first through holes and the second through holes in sequence, so that the model piece can rotate around the axis of the rotating rod.

[0011] Furthermore, the limiting member includes a base plate fixed to the top surface of the end of the base plate and a limiting plate detachably connected to the base plate via a plug-in structure.

[0012] Furthermore, the plug-in structure includes a plug-in groove formed on the base plate and a plug-in strip fixed on the limiting plate and adapted to the plug-in groove, wherein there are two plug-in strips and two plug-in grooves.

[0013] Furthermore, the model component includes a support plate, a shape plate mounted on the support plate, and a plurality of reinforcing plates, wherein the plurality of reinforcing plates are disposed on the side of the shape plate away from the mold cavity. Attached Figure Description

Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Please see Figures 1 to 2 The image shows a concrete mold according to an embodiment of the present invention, comprising a base plate 10, model parts 20 symmetrically arranged on both sides of the base plate 10 and rotatable around the sides of the base plate 10, and limiting members 40 detachably installed on the top surfaces at both ends of the base plate 10. The model parts 20 have a limiting state and an open state. In the limiting state, the two model parts 20, the two limiting members 40, and the base plate 10 together form a mold cavity 50. In the open state, the model parts 20 separate from the limiting members 40, thereby releasing the mold cavity 50. A limiting structure 30 is detachably installed between the two model parts 20 to lock the model parts 20 in the limiting state.

[0027] In this embodiment, multiple limiting structures 30 may be provided at intervals between the two model parts 20.

[0028] It is worth noting that the vertical insertion and removal action of the limiting structure 30 achieves instantaneous locking (limited state) or release (non-limited state) of the model part 20. This design completely abandons the traditional progressive tightening process of bolts, reduces the time required for single-point locking, and eliminates the need for auxiliary tools such as wrenches, thus reducing the intensity of manual labor. The rotation mechanism of the model part 20 around the side of the base plate 10 supports free adjustment of the angle from 0° (fully closed) to 90°-110° (demolding preparation position), giving the mold opening and closing action a very high degree of operational freedom. The modular design of the detachable limiting component 40 eliminates the vibration and impact caused by traditional bolt disassembly, reducing the surface damage rate of concrete components. Combined with the rigid constraint mechanism of the limiting structure 30 on the two model parts 20, the technical defect of easy loosening of rotatable molds is solved.

[0029] Please see Figures 3 to 5 As shown in the figure, the limiting structure 30 includes a fixing plate 31 respectively disposed on the side of the two model parts 20 away from the base plate 10, a limiting through hole 32 opened on the top of the fixing plate 31 and penetrating both sides of the fixing plate 31, a fixing rod 33 adapted to the limiting through hole 32, a fixing part 34 connected to one end of the fixing rod 33, and a disassembly part 35 detachably disposed on the other end of the fixing rod 33, so that the disassembly part 35 cooperates with the fixing part 34 to press the two fixing plates 31 to achieve locking.

[0030] Furthermore, the disassembly part 35 includes a plug-in block 351 and a limiting block 352 vertically fixed to the top of the plug-in block 351. The plug-in block 351 and the limiting block 352 form a T-shaped structure. The other end of the fixing rod 33 is provided with a plug-in hole 353 that is adapted to the plug-in block 351. When the plug-in block 351 is inserted into the plug-in hole 353, the bottom of the plug-in block 351 abuts against the fixing plate 31 and is located at the bottom of the limiting through hole 32. The two ends of the limiting block 352 abut against the fixing plate 31 and are located at the two ends of the limiting through hole 32.

[0031] In practice, the two model parts 20 are first rotated to their limit positions. Then, the fixing rod 33 is inserted into the limiting through hole 32 between the two opposing fixing plates 31. At this time, the fixing part 34 at one end of the fixing rod 33 abuts against one of the fixing plates 31. Next, the insertion block 351 of the disassembly part 35 is inserted into the insertion hole 353 of the fixing rod 33. When the insertion block 351 is fully inserted through the insertion hole 353, the bottom of the insertion block 351 abuts against the bottom of the other fixing plate 31 and the limiting through hole 32, while the two ends of the limiting block 352 abut against the two ends of the other fixing plate 31 and the limiting through hole 32, respectively. At this time, the two opposing fixing plates 31 are abutted by the fixing part 34 and the insertion part, respectively, and are thus limited between the fixing part 34 and the insertion part, thereby locking the model part 20 in the limit position.

[0032] When disassembly is required, pull out the disassembly part 35, and the limiting effect on the two fixing plates 31 will disappear. The locking of the model part 20 in the limiting state will also be released. Then, rotate the model part 20 to the open state.

[0033] This single-point locking / unlocking method, achieved through the cooperation of the fixing rod 33 and the disassembly part 35, can shorten the operation time. At the same time, the bottom surface of the plug block 351 can resist vertical separation, the limiting block 352 can laterally restrain horizontal displacement, and the T-shaped structure can also self-lock to prevent accidental dislodgement.

[0034] Furthermore, the cross-sections of the plug block 351 and the plug hole 353 are rectangular. The rectangular cross-section plug block 351 eliminates rotational degrees of freedom.

[0035] Furthermore, multiple first rotating plates 11 are spaced apart on both sides of the base plate 10, each with a first through hole 12. Multiple second rotating plates 13 are spaced apart on the side of the model component 20 closest to the base plate 10, each with a second through hole 14. All the first through holes 12 and the second through holes 14 pass through a rotating rod 15 in sequence, allowing the model component 20 to rotate around the axis of the rotating rod 15. The first and second rotating plates 13 are staggered, distributing the force on the rotating rod 15 to multiple points.

[0036] Please see Figures 6 to 8 Specifically, the limiting member 40 includes a base plate 41 fixed to the top surface of the end of the base plate 10, and a limiting plate 43 detachably connected to the base plate 41 via a plug-in structure 42.

[0037] More specifically, the insertion structure 42 includes an insertion slot 421 formed on the base plate 41 and an insertion strip 422 fixed on the limiting plate 43 and adapted to the insertion slot 421. There are two insertion strips 422 and two insertion slots 421. The limiting plate 43 is designed separately from the base plate 41, allowing for individual replacement in case of partial damage.

[0038] Specifically, the model component 20 includes a support plate 21, a shape plate 22 mounted on the support plate 21, and a plurality of reinforcing plates 23, wherein the plurality of reinforcing plates 23 are disposed on the side of the shape plate 22 away from the mold cavity 50.

[0039] In summary, the building concrete mold in the above embodiments of this utility model has the following beneficial effects:

[0040] First, place the base plate 10 horizontally, so that the second rotating plate 13 of the model part 20 and the first rotating plate 11 of the base plate 10 are arranged alternately. The rotating rod 15 passes through the first through hole 12 and the second through hole 14 in sequence to form a rotatable hinge structure. Then, rotate the two model parts 20 inward around the axis of the rotating rod 15 to a vertical position, with the rotation angle α controlled between 40° and 90°; at the same time, align the insertion strip 422 of the limiting plate 43 with the insertion slot 421 of the base plate 41, and press it down vertically until the insertion strip 422 is fully inserted.

[0041] After initial assembly, rotate the two model parts 20 to their limit positions and insert the fixing rod 33 into the limiting through hole 32 between the two opposing fixing plates 31. At this time, the fixing part 34 at one end of the fixing rod 33 will abut against one of the fixing plates 31. Next, insert the plug block 351 of the disassembly part 35 into the plug hole 353 of the fixing rod 33. When the plug block 351 is completely inserted through the plug hole 353, its bottom will abut against the bottom of the other fixing plate 31 and the limiting through hole 32. The two ends of the limiting block 352 abut against the two ends of the other fixing plate 31 and the limiting through hole 32, respectively, so that the two opposing fixing plates 31 are abutted and limited by the fixing part 34 and the plug block, thereby locking the model parts 20 in the limit position. At this time, the two model parts 20, the two limiting parts 40 and the base plate 10 together form a mold cavity 50, into which concrete can be poured.

[0042] After the concrete has hardened, disassemble the model. Lift the disassembly part 35 to disengage the insertion block 351 from the insertion hole 353, pull out the fixing rod 33, and release the limiting effect on the two fixing plates 31. The locking state of the model part 20 will then disappear. Then rotate the model part 20 to the open state, and then lift the limiting plate 43 vertically to disengage the insertion strip 422 from the insertion groove 421, and the concrete component can be removed.

[0043] The design of this concrete mold achieves instantaneous locking or releasing of the model component 20 through the vertical insertion and extraction action of the limiting structure 30. Compared to the gradual tightening process of traditional bolts, the single-point locking action significantly reduces time consumption and eliminates the need for auxiliary tools such as wrenches, thus reducing the intensity of manual labor. The rotation mechanism of the model component 20 around the side of the base plate 10 supports free adjustment of the angle from 0° (fully closed) to 90°-110° (demolding preparation position), giving the mold opening and closing action a very high degree of operational freedom. The modular design of the detachable limiting component 40 avoids the vibration and impact generated during the disassembly of traditional bolts, reducing the surface damage rate of concrete components; combined with the rigid constraint mechanism of the limiting structure 30 on the two model components 20, it effectively solves the technical defect of easy loosening of rotatable molds.
