Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and more specifically, relates to a mold and a construction process thereof for facilitating the splicing of reinforced concrete components. Background Art

[0002] In the field of construction, reinforced concrete prefabricated components are widely used due to their high construction efficiency and stable quality. However, the molding quality and production efficiency of prefabricated components largely depend on the performance of the mold. Currently, the existing reinforced concrete component splicing molds have the following technical problems in practical application:

[0003] Molds have poor versatility and a limited range of adaptability: Traditional molds are mostly fixed structures, and one mold can only produce prefabricated parts of a specific shape (such as a rectangle). If special-shaped components need to be produced, the mold frame needs to be replaced as a whole. Not only is the equipment investment cost high, but the replacement process also requires the disassembly of all connecting parts, seriously affecting the construction progress.

[0004] The assembly and disassembly process is cumbersome and difficult to operate: Existing molds are often connected using bolts or welded joints. Disassembly requires multiple tools, such as wrenches and crowbars, making it difficult for a single person to complete the operation. For example, the fixing structure between the mold and the base often requires the coordination of multiple people to loosen it. Repeated assembly and disassembly can easily cause wear on the connecting parts, reducing the mold's service life.

[0005] Insufficient quality control of prefabricated parts: Traditional molds lack effective degassing and density-enhancing devices. After concrete pouring, bubbles are difficult to expel, resulting in honeycombs and voids inside the prefabricated parts, which require later finishing and increase additional process costs.

[0006] Rigid and inefficient production models: Existing mold bases are mostly fixed, integrated structures. After precast parts are formed, they must be moved manually using a crane or forklift. This is not only laborious but also prone to vibrations that can cause deformation of unset concrete during handling. Furthermore, the long turnaround time from pouring to demolding a single mold makes continuous production impossible.

[0007] In response to the above problems, there is an urgent need for a reinforced concrete component splicing mold that is highly versatile, easy to assemble and disassemble, has controllable quality, and can achieve efficient production to meet the diverse and efficient needs of modern construction for prefabricated components. Summary of the Invention

[0008] In order to solve the above technical problems, the present invention provides a mold and a construction process for facilitating the splicing of reinforced concrete components to solve the above problems.

[0009] A mold for facilitating the splicing of reinforced concrete components, comprising a bottom component, a surrounding component, and a mold component;

[0010] The bottom assembly includes a fixed base, a deflection base and a crossbeam. The fixed base and the deflection base are connected by hinges to form a complete base. A circular splicing groove is provided on the complete base.

[0011] The enclosure assembly includes four mounting base rods, each of which has three equally spaced annular grooves on its face, and two splicing rods attached to its face;

[0012] The mold assembly includes four connecting frames, each of which is welded with an L-shaped mold splicing piece;

[0013] Four mold parts are joined together to form a rectangular concrete mold;

[0014] A bottom plate is provided at the bottom of the four connecting frames, and four ring-shaped array slots are opened on the edge of the bottom plate.

[0015] Preferably, the mold splicing pieces can be replaced with special-shaped structures, and four mold splicing pieces are spliced ​​into a special-shaped concrete mold. The transverse lengths of the four connecting pieces change as the mold splicing pieces are replaced, and the splicing surfaces of the four mold splicing pieces are sealed.

[0016] Preferably, the fixed base and the deflection base are both fixedly connected with a semi-cylindrical threaded connection column, the cylindrical surfaces of the two threaded connection columns are threadedly sleeved with splicing screw rings, and the crossbeam is fixedly installed at the bottom of the fixed base;

[0017] Among them, an electric telescopic rod is fixed on the crossbeam, and anti-slip bases are fixed to the bottom surfaces of the crossbeam and the fixed base. A universal pulley is installed at the bottom of the deflection base, and the telescopic rod of the electric telescopic rod is located at the center of the splicing groove.

[0018] Preferably, the bottoms of the two mounting base rods on the left are fixed to the fixed base, and the bottoms of the two mounting base rods on the right are fixed to the deflection base;

[0019] When the fixed base and the deflection base are combined together, the four mounting base rods are arranged in a circular array with the center of the splicing groove as the axis.

[0020] Preferably, on the same mounting base rod, one splicing rod is fixedly connected to two swivels, and the other splicing rod is fixed to one swivel, and the three swivels are rotatably sleeved in the three annular grooves on the mounting base rod respectively;

[0021] A quarter-circular plate is fixed on the upper end of each splicing rod, and a semi-cylindrical splicing column is fixedly connected to each quarter-circular plate. Connecting screw rings are threadedly sleeved on the two splicing columns on the same mounting base rod.

[0022] Preferably, a quarter-circular plate is attached to the upper surface of the mounting base rod, an arc groove is provided on each splicing rod, the middle part of the arc groove passes through the rod surface of the splicing rod, a sealing pad layer is laid on the upper surface of the bottom plate, four plug rods are fixedly connected to the bottom plate, the upper end of the plug rod is a threaded end, and the four slots are respectively engaged with the lower ends of the four mounting base rods.

[0023] Preferably, each connecting frame is penetrated by a slot, and the four slots are movably connected to the four insertion rods respectively, and a sealing plate is placed on the upper end of the four connecting parts. After the four insertion rods pass through the sealing plate, the nuts are threadedly connected to make the sealing plate press against the connecting parts. The separated ends of the four connecting parts are fixedly connected with an arc rod, and the middle part of the arc rod is fixedly connected to the connecting part. The arc rod is movably clamped with the two spliced ​​arc grooves, and a clamping plate is fixed at the bottom of the base plate, and the clamping plate is clamped in the splicing groove. A circle of universal wheels is installed on the bottom surface of the clamping plate.

[0024] Another technical problem to be solved by the present invention is to provide a construction process for a mold that facilitates the splicing of reinforced concrete components, comprising the following steps:

[0025] S1: Assemble and adapt the mold. Turn the connecting screw to disengage the splicing column, separate the two splicing rods on the same mounting base, slide the arc groove off the arc rod, and separate the connecting frame from the splicing rod upward along the slot. Remove the four connecting frames, replace them with new connecting frames and mold splicing parts to form a new mold, merge the two splicing rods on the same mounting base, and use the connecting screw to fix the two splicing columns together.

[0026] S2: Concrete pouring preparation and operation: Place a concrete skeleton in the mold composed of four mold parts and pour concrete. During the pouring process, the electric telescopic rod on the beam hits the bottom of the mold to vibrate and eliminate bubbles. After pouring is completed, cover it with a sealing plate and use the nuts on the four rods to press the sealing plate against the upper end of the mold parts to achieve a sealed mold.

[0027] S3: Mold disassembly and movement: After the sealing plate is covered, separate the two splicing rods on the same mounting base rod again to separate the arc groove from the arc rod. Turn the splicing ring on the threaded connection column to separate the two threaded splicing columns. Rotate the deflection base to release the restriction on the base plate. Move the base plate through the universal wheel, driving the base plate and the mold on it to move to the storage area.

[0028] S4: Circular construction. After the previous mold is removed, the new mold is moved into the splicing groove, the deflection base is closed, and the two threaded splicing columns are fixed with splicing screws to limit the position of the new base plate. The splicing rods on the installation base rods are combined to fix the new mold and the next concrete pouring is carried out. The assembly line production is realized by continuously disassembling and assembling the mold.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The mold is highly versatile and adaptable to a wide range of applications: The mold components can be replaced with special-shaped structures such as rectangular and circular ones according to prefabrication requirements, and the horizontal length of the connectors is adjusted synchronously with the mold components. When replacing, simply turn the connecting screw to separate the splicing column, so that the arc groove is separated from the arc rod. The original connecting frame and mold components can be removed, and the new components can be replaced and then secured with the connecting screws. There is no need to replace the bottom component and the surrounding component. It can adapt to the prefabrication of reinforced concrete components of various shapes, greatly improving the mold reuse rate and reducing equipment investment costs.

[0031] 2. Convenient assembly and disassembly, flexible operation: The splicing rod is inserted into the annular groove of the mounting base rod via a swivel, allowing for flexible rotation. To separate, the splicing column is separated by rotating the connecting screw ring, and the arc groove slides along the curved rod, allowing for quick separation of the connecting frame and splicing rod. The fixed base and deflection base are secured by threaded connecting columns and splicing screw rings. Rotating the screw ring separates the two, and the universal pulley on the deflection base easily removes the constraints on the base plate. The entire disassembly and assembly process requires no complex tools and can be performed by a single person, reducing labor costs and operating difficulty, and facilitating routine maintenance and mold replacement.

[0032] 3. Improve the quality of precast parts: The electric telescopic rod on the crossbeam precisely strikes the center of the splicing groove, generating high-frequency vibrations in the mold, which forces bubbles inside the concrete to rise and discharge, reducing defects such as honeycombs and voids. After pouring, the sealing plate is tightly pressed against the upper end of the mold splicing parts using the nuts on the rods. Combined with the sealing pad layer on the bottom plate, this prevents excessive moisture loss in the concrete and ensures slow solidification. Furthermore, the non-slip base enhances mold stability, and the vibration allows the concrete to fully fill the gaps in the steel skeleton, making the precast part more dense.

[0033] 4. Ease of movement and assembly line production: The universal pulley at the bottom of the deflection base allows it to rotate around the hinge. After the threaded connection column is separated, the universal wheel at the bottom of the base plate can easily move the mold and prefabricated parts to the storage area, eliminating the laborious operation of manual handling. The fixed base does not need to be moved, and the new mold can be directly moved into the splicing slot. After closing the deflection base, it is fixed with the splicing screw ring. After the splicing rod is connected, the next pour can begin. This significantly shortens the process interval, realizes continuous assembly line production, and increases the average daily prefabrication output.

[0034] 5. Reliable sealing performance ensures a perfect pouring effect: High-pressure sealing strips are embedded in the joints of the mold components, which are squeezed to fill the gaps after splicing. The rubber sealing pad on the bottom plate fits tightly against the bottom of the mold components, preventing concrete from leaking from the bottom. The sealing plate, when tightened with nuts, forms a sealed space with the upper end of the mold components, reducing the risk of surface cracking after concrete pouring. This multi-sealing design significantly improves the appearance quality of the precast parts after molding. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0044] See also Figure 1-Figure 7 The present invention provides a mold and a construction process for convenient splicing of reinforced concrete components. The mold includes a bottom component, a surrounding component and a mold component. Through the coordinated cooperation of the components, convenient prefabrication and splicing of reinforced concrete components can be achieved.

[0045] In the base assembly, the fixed base 1 and the deflecting base 4 are connected by hinges, forming a complete base. A circular joint groove 6 is provided on the base to provide a reference for mold positioning. Semi-cylindrical threaded connecting posts 5 on the fixed base 1 and the deflecting base 4, combined with threaded joint rings, ensure secure connection and separation between the two. A crossbeam 7 is fixed to the bottom of the fixed base 1. An electric telescopic rod on the crossbeam can strike the center of the joint groove 6, helping to eliminate bubbles during concrete pouring. Anti-slip bases on the bottom surfaces of the crossbeam 7 and the fixed base 1 enhance stability, while a universal pulley on the bottom of the deflecting base 4 facilitates rotation and adjustment of the base.

[0046] The four mounting base rods 3 of the enclosure assembly have two bottoms fixed to the fixed base 1 on the left side and two bottoms fixed to the deflection base 4 on the right side. When the two are combined, the four mounting base rods 3 form a circular array with the center of the splicing groove 6 as the axis. The two splicing rods 16 on the same mounting base rod 3 are rotatably sleeved in the annular groove 20 through the swivel 15, and can be flexibly rotated to adjust the position. The quarter-circular plate 19 and the splicing column 18 at the upper end of the splicing rod 16 cooperate with the connecting screw ring 17 to achieve a stable splicing of the two splicing rods 16. The arc groove 21 on the splicing rod 16 is movably engaged with the arc rod 12 of the connecting frame 2 to ensure the stability of the connection between the mold assembly and the enclosure assembly.

[0047] The mold assembly's four connecting frames 2 are welded with L-shaped mold connectors 8, which can be assembled to form rectangular concrete molds or replaced with custom-shaped mold connectors to create special-shaped concrete molds. The horizontal length of the connecting frames 2 adjusts with the mold connectors 8, and the joints are sealed to prevent grout leakage. The bottom plate 13 of the connecting frame 2 has a slot 14 that engages with the lower end of the mounting base rod 3. The insertion rod 10 passes through the slot 11 of the connecting frame 2, and the threaded end at the top engages a nut to secure the sealing plate 9. A sealing pad layer on the bottom plate 13 further enhances the seal, and universal wheels at the bottom facilitate mold movement.

[0048] In actual application, the specific operations are as follows:

[0049] If a concrete component of a specific shape is to be prefabricated, the mold must be assembled and adapted first. Rotate the connecting screw 17 to disengage the splicing column 18, separating the two splicing rods 16 on the same mounting base 3. The arcuate slot 21 then slides away from the arcuate rod 12. Follow the slot 11 upward to separate the connecting frame 2 from the splicing rods 16. Remove the four connecting frames 2 and replace them with new, adapted connecting frames 2 and mold splicing components 8 to form a new mold. Then, merge the two splicing rods 16 on the same mounting base 3, aligning the two splicing columns 18. Secure with the connecting screw 17 to complete the mold assembly.

[0050] After the mold is assembled, concrete is poured. A concrete skeleton is placed within the mold formed by the four mold components 8, and then concrete is poured. During the pouring process, the electric telescopic rod on the crossbeam 7 is activated, causing it to strike the bottom, causing the mold to vibrate, helping to eliminate bubbles in the concrete and ensure the concrete is dense. After pouring, the sealing plate 9 is placed on the cover. Using the nuts on the four inserts 10, the sealing plate 9 is tightly pressed against the upper ends of the mold components 8, achieving a sealed mold and ensuring the quality of the concrete.

[0051] After the concrete pouring is complete, the mold is removed. After the sealing plate 9 is installed, the two splicing rods 16 on the same mounting base rod 3 are separated again, allowing the arcuate groove 21 to disengage from the arcuate rod 12. The splicing ring on the threaded connecting column 5 is rotated to separate the two threaded connecting columns 5. The deflection base 4 is then rotated to release the restraints on the base plate 13. The base plate 13 is moved using the universal wheels at its bottom, thereby moving the base plate 13 and the mold above it to a storage area to await the solidification of the precast parts.

[0052] When continuous production is required, a cyclic construction process is implemented. After the previous mold is removed, the new mold is moved into the splicing slot 6, the deflection base 4 is closed, and the two threaded connecting columns 5 are secured with splicing screws to limit the position of the new base plate 13. The splicing rods 16 on the base rod 3 are then installed to further secure the new mold, and the next concrete pour can be carried out. The fixed base 1 does not need to be moved, and the continuous assembly and disassembly of the mold enables assembly line production, greatly improving construction efficiency.

[0053] The structures and functions of this mold:

[0054] Fixed base 1: Serving as the fixed foundation of the entire device, it is rotatably connected to the deflection base 4 through a hinge, providing an installation platform for other components. The anti-slip base on its bottom surface can enhance the stability of the device during construction and prevent displacement.

[0055] Deflection base 4: cooperates with the fixed base 1 to form a complete base. The universal pulley at the bottom facilitates its rotation around the hinge, thereby removing the restriction on the bottom plate 13 and facilitating the movement of the mold.

[0056] Threaded connecting column 5: fixed on the fixed base 1 and the deflection base 4, it is semi-cylindrical. The two threaded connecting columns 5 cooperate with the splicing screw ring to achieve stable connection and separation of the fixed base 1 and the deflection base 4, ensuring the integrity of the base assembly.

[0057] Splicing groove 6: It is opened on the complete base and is circular, providing a reference for the positioning of the mold assembly to ensure the accurate installation position of the mold.

[0058] Crossbeam 7: Attached to the bottom of the fixed base 1, it is used to mount the electric telescopic rod. The anti-skid base on its bottom surface further enhances the stability of the device. The electric telescopic rod can strike the center of the splicing groove 6, causing the mold to vibrate and help eliminate bubbles during concrete pouring.

[0059] Mounting base rods 3: There are four in total, two on the left are fixed on the fixed base 1, and two on the right are fixed on the deflection base 4. When the bases are assembled, a ring array with the center of the splicing groove 6 as the axis is formed, which plays a surrounding and supporting role for the mold assembly and provides an installation carrier for the splicing rod 16.

[0060] Annular groove 20: opened on the surface of the mounting base rod 3, three equidistantly distributed, for sleeve mounting the swivel 15, so that the splicing rod 16 can rotate around the mounting base rod 3, facilitating the installation and removal of the mold assembly.

[0061] Splicing rods 16: Two are attached to each mounting base rod 3 and are connected to the mounting base rod 3 via a swivel 15, allowing for flexible rotation. The quarter-circular plate 19 at the upper end and the splicing column 18 cooperate with the connecting screw 17 to achieve a stable splicing of the two splicing rods 16, thereby securing the mold assembly.

[0062] The swivel 15 is fixed on the splicing rod 16 and is sleeved in the annular groove 20, so that the splicing rod 16 can rotate relative to the mounting base rod 3, providing convenience for the disassembly and assembly of the mold assembly.

[0063] Splicing column 18: fixed on the quarter-circular plate 19, in a semi-cylindrical shape, the two splicing columns 18 are fitted together and fixed by connecting screw rings 17 to achieve the connection and fixation of the splicing rod 16.

[0064] Connecting screw ring 17: Threaded onto the two splicing columns 18, tightening the splicing columns 18 to ensure the stability of the connection of the splicing rod 16.

[0065] The arc groove 21 is provided on the splicing rod 16 , with the middle portion penetrating the rod surface and movably engaged with the arc rod 12 of the connecting frame 2 , thereby enhancing the stability of the connection between the mold assembly and the surrounding assembly.

[0066] Connecting frame 2: There are four in total, with the mold splicing piece 8 welded on the top and the bottom connected to the base plate 13, which plays the role of connecting and supporting the mold splicing piece 8. Its horizontal length can be changed with the replacement of the mold splicing piece 8 to adapt to molds of different shapes.

[0067] Mould splicing parts 8: Four splicing parts can form a rectangular or special-shaped concrete mould, which is the cavity for concrete molding. The splicing surface is sealed to prevent concrete leakage.

[0068] Bottom plate 13: The bottom of the connecting frame 2 is fixed on it, and the groove 14 on the edge is engaged with the lower end of the mounting base rod 3 to position the mold assembly. The sealing gasket layer on the upper surface enhances the sealing performance, and the universal wheels at the bottom facilitate the movement of the mold.

[0069] The card slot 14 is engaged with the lower end of the mounting base rod 3 to ensure that the mold assembly is accurately installed on the bottom assembly.

[0070] Insert rod 10: fixed on the bottom plate 13, with the upper end being a threaded end, passing through the slot 11 of the connecting frame 2, and cooperating with the nut to fix the sealing plate 9, thereby enhancing the airtightness of the mold.

[0071] Slot 11 is provided on the connecting frame 2 for the insertion rod 10 to pass through, so as to facilitate the connection and disassembly of the connecting frame 2 and the bottom plate 13 .

[0072] The arc-shaped rod 12 is fixed to the separated end of the connecting frame 2 and is movably engaged with the arc-shaped groove 21 of the splicing rod 16 to enhance the connection stability between the connecting frame 2 and the surrounding assembly.

[0073] Sealing plate 9: Covers the upper end of the mold assembly 8 and is pressed tightly by the nut on the insertion rod 10 to seal the upper end of the mold to prevent water from evaporating too quickly and debris from entering after concrete pouring.

[0074] Sealing method between molds:

[0075] Sealing the joints of the four mold joints 8: Sealing strips or rubber pads are used to seal the joints. During assembly, the strips or pads are squeezed, filling the gaps and effectively preventing concrete leakage during pouring. For special-shaped molds, after replacing the mold joints 8, the joints are also sealed with appropriate sealing strips or rubber pads to ensure a good seal.

[0076] The bottom plate 13 and the mold assembly 8 are sealed: an elastic sealing pad layer (such as a rubber pad layer) is laid on the upper surface of the bottom plate 13. When the mold assembly 8 is installed on the bottom plate 13, the bottom of the mold assembly 8 is tightly fitted with the sealing pad layer. The sealing pad layer is deformed by the gravity of the mold itself and the fixing force of the connecting frame 2, filling the gap between the bottom plate 13 and the mold assembly 8, thereby achieving bottom sealing.

[0077] Upper end sealing: After the concrete pouring is completed, cover the sealing plate 9 and tighten it with the nuts on the four plug rods 10 so that the sealing plate 9 is tightly against the upper end surface of the mold assembly 8. A thin rubber pad can be set between the sealing plate 9 and the upper end surface of the mold assembly 8. The rubber pad is deformed by the pressure of the nut to achieve sealing of the upper end of the mold to prevent moisture loss in the concrete and entry of debris.

[0078] Sealing of the connection part: A sealing ring can be provided on the inner wall of the slot 11 at the fitting part between the rod 10 and the slot 11. When the rod 10 is inserted into the slot 11, the sealing ring is in close contact with the surface of the rod 10 to prevent the concrete slurry from leaking from this part.

[0079] The use of electric telescopic rod:

[0080] Assisted elimination of concrete bubbles: During the concrete pouring process, the electric telescopic rod regularly hits the center position of the splicing groove 6, causing the entire mold to vibrate, prompting the bubbles inside the concrete to move upward and be discharged, reducing the residual bubbles in the concrete.

[0081] Enhance the density of concrete: Through continuous vibration, the concrete can flow better in the mold and fill every corner, especially the gaps around the steel skeleton, thereby improving the density of the concrete.

[0082] Reducing residual bubbles prevents defects such as cavities and honeycombs within the concrete, thereby enhancing the structural strength and durability of precast parts and reducing the risk of damage caused by structural defects during later use. It also ensures a more even distribution of concrete within the mold, ensuring the dimensional accuracy and appearance quality of the precast parts and reducing deformation or localized strength deficiencies caused by uneven concrete distribution.

[0083] The electric telescopic rod is fixedly mounted on the crossbeam 7, with its end positioned at the center of the splicing slot 6. During the concrete pouring process, the electric telescopic rod reciprocates and retracts at a set frequency and amplitude. The end of the rod periodically strikes the bottom area corresponding to the splicing slot 6 (or, by transmitting vibration, causes the entire mold to vibrate), thereby vibrating the mold and the concrete inside. The core principle of the electric telescopic rod is to drive the motor forward and reverse, transmitting power through the reduction gear, driving the screw to rotate, causing the nut on the screw to move axially, thereby driving the telescopic rod to extend and retract. When the motor rotates forward, the telescopic rod extends and strikes the bottom; when the motor rotates backward, the telescopic rod retracts, preparing for the next strike. This reciprocating motion creates continuous vibration output, providing auxiliary functions during the concrete pouring process.

[0084] Working principle:

[0085] When the mold is in use, the mold splicing piece 8 is replaced according to the shape of the concrete piece to be prefabricated. Here, the square ( Figure 2 ) or round ( Figure 3 ) as an example to show the usage process:

[0086] S1: First, install the mold:

[0087] Turn the connecting screw 17 to separate it from the splicing column 18, and then separate the two splicing rods 16 on the same mounting base rod 3. During the separation process, the arc groove 21 slides away from the arc rod 12. At this time, the connecting frame 2 can be separated from the splicing rod 16 upward along the slot 11, so that the four connecting frames 2 can be removed, and replaced with a new connecting frame 2 and the mold splicing piece 8 to form a new mold. Then, merge the two splicing rods 16 on the same mounting base rod 3, and use the connecting screw 17 to fix the two fitted splicing columns 18;

[0088] S2: Then pour concrete:

[0089] A concrete skeleton is placed in the mold formed by the four mold splicing pieces 8 and then concrete is poured. During the pouring process, the electric telescopic rod on the crossbeam 7 hits the bottom to vibrate the mold to help eliminate bubbles. After the pouring is completed, the sealing plate 9 is covered and the nuts on the four insert rods 10 are used to make the sealing plate 9 press against the upper end of the mold splicing piece 8 to make the entire mold airtight.

[0090] S3: Remove the mold:

[0091] After the sealing plate 9 is covered, the two splicing rods 16 on the same mounting base rod 3 are separated again to separate the arc groove 21 from the arc rod 12, and the splicing screw ring on the threaded connection column 5 is rotated to separate the two threaded connection columns 5. Then, the deflection base 4 is rotated so that the movement of the bottom plate 13 is no longer restricted. At this time, the bottom plate 13 can be moved by the universal wheel, thereby driving the bottom plate 13 and the mold above it to move together, so that the entire model can be moved to the storage place to wait for the prefabricated parts to be prepared.

[0092] S4: Continue preparation:

[0093] After the previous mold is removed, the new mold can be moved into the splicing groove 6, and then the deflection base 4 is closed, and the two threaded connecting columns 5 are fixed with the splicing screw ring to limit the position of the new base plate 13, and then the splicing rod 16 on the installation base rod 3 is combined to further fix the new mold. The next concrete pouring can be carried out, and the fixed base 1 does not need to be moved. The assembly line production can be completed by continuously disassembling and assembling the mold, which is more convenient.
