Description

Technical Field

[0001] The invention relates to the technical field of concrete component production and manufacturing, and specifically proposes a manufacturing device and a manufacturing method for a concrete hollow formwork for a wall structural column. Background Art

[0002] The use of precast concrete hollow formwork to assist in the casting and forming of wall structural columns is a common construction method. Traditional cast-in-place concrete wall structural columns require on-site formwork, steel bar tying and concrete pouring. The process is cumbersome and time-consuming. The use of precast hollow formwork can greatly reduce the amount of on-site construction work. The concrete hollow formwork is prefabricated in the factory according to the required specifications and standards. After forming, it can be transported in batches to the construction site for installation, which greatly shortens the on-site preparation and construction time for pouring wall structural columns. The interior of the precast concrete hollow formwork is a hollow structure, which reduces the amount of concrete used, thereby reducing material costs. At the same time, the size and shape of the precast concrete hollow formwork can be strictly controlled during factory production, thereby ensuring the construction accuracy of the wall structural columns and improving the overall quality of the structure. Therefore, this construction method has the advantages of improving work efficiency, reducing costs, improving structural quality, and enhancing structural stability.

[0003] At present, hollow concrete formworks need to be cast and formed in a standardized manner using prefabricated casting molds. Prefabricated casting molds are usually steel plate mold frame structures, and under existing technologies, a single mold frame is usually used for corresponding casting. Before casting, the mold frame needs to be assembled and locked by screws or other locking materials or structures. During casting, it is necessary to cast, vibrate and transport one by one. After forming, each mold frame needs to be demolded one by one, and batch forming operations are not realized. Therefore, too many repeated operations are performed in the process of forming one by one using a single mold frame, which wastes time and energy and reduces production efficiency. In addition, frequent manual disassembly and assembly of the mold makes the mold template more prone to deformation and wear, affecting its service life. Summary of the Invention

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] A manufacturing device for concrete hollow formwork for wall structural columns, mainly used for Figure 11The shown concrete hollow formwork 6 is prefabricated and processed. The hollow formwork 6 is in a U-shaped frame structure. During the on-site construction of the wall construction columns, multiple hollow formworks 6 are spliced and used one by one to replace the on-site formwork support.

[0042] As Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 11 shown, the manufacturing equipment includes a pouring mold 1 for pouring the hollow formwork 6. The pouring mold 1 includes a bottom template 11 in a cross-plate structure, an external mold frame 13 positioned and inserted into the bottom template 11, and an internal mold frame 12 sleeved inside the external mold frame 13. Both the internal mold frame 12 and the external mold frame 13 are in a cross-frame structure. In order to increase the contact surface between the bottom end after assembly and the bottom template 11 to enhance the sealing performance at the splicing joint, therefore, an inner side plate 121 contacting the bottom template 11 is welded around the inner frame edge at the bottom end of the internal mold frame 12, and an outer side plate 131 contacting the bottom template 11 is welded around the outer frame edge at the bottom end of the external mold frame 13. On the upper plate surface of the bottom template 11, a positioning stop edge 111 is arranged along the plate edge. The outer side plate 131 is positioned and inserted into the positioning stop edge 111. When the external mold frame 13 is inserted into the positioning stop edge 111 through the outer side plate 131, the bottom template 11 realizes the constraint positioning of the external mold frame 13, and the internal mold frame 12 is sleeved inside the external mold frame 13 and is in tight contact with each other, realizing the constraint positioning between the internal mold frame 12 and the external mold frame 13, thereby indirectly forming the relative positioning between the bottom template 11 and the internal mold frame 12. The bottom template 11, the internal mold frame 12, and the external mold frame 13 jointly divide and form four pouring cavities 14. The pouring cavities 14 are in a U-shape and correspond to the size of the required poured hollow formwork 6. In the present invention, through the setting of multiple pouring cavities 14 in a single pouring mold 1, the batch pouring of a single mold frame can be realized.

[0043] As <​​​​​​​​​​​​​​​As shown, the mold clamping hanger 2 includes a positioning frame 3 that fits over four guide posts 112. The positioning frame 3 includes four sleeve posts 31 that slide and fit in a one-to-one correspondence with the four guide posts 112. The sleeve posts 31 are rectangular sleeve structures. A top plate 32 is welded horizontally and flush between the top ends of the four sleeve posts 31. A bottom plate 33 is welded horizontally and flush between the bottom ends of the four sleeve posts 31. A lead screw 34 is mounted on the bottom plate 33 for vertical rotation via a bearing. The lead screw 34 passes upward through the top plate 32. To facilitate rotation and lifting, a lifting ring 341 is welded to the top of the lead screw 34. The mold clamping hanger 2 can be docked at the lifting end of an existing overhead crane, and the lifting end can be specifically hooked on the lifting ring 341.

[0045] like Figure 3 、 Figure 8 and Figure 10 As shown, the positioning frame 3 is equipped with a locking mechanism 4 driven by a lead screw 34 and locking the positioning frame 3 on the four guide columns 112; the locking mechanism 4 includes a stroke cylinder 41 that vertically penetrates and slides on the top plate 32, and a sliding shaft 42 is vertically slidably installed at the bottom of the stroke cylinder 41. The sliding shaft 42 is a hollow tube structure, and a keyway is provided on the sliding shaft 42, and a spline that cooperates with the keyway is provided in the stroke cylinder 41; a hinged end 43 is horizontally welded to the bottom end of the sliding shaft 42, and a spring 44 is sleeved on the sliding shaft 42. The two ends of the spring 44 are respectively welded to the bottom end of the stroke cylinder 41 and the top end of the hinged end 43, and the lead screw 34 passes through the hinged end 43, the sliding shaft 42 and the stroke cylinder 41 in turn, and the stroke cylinder 41 is threadedly connected to the lead screw 34; four connecting rods 45 are hinged on the hinged end 43, and the other ends of the four connecting rods 45 correspond to the hinges A locking plate 46 is connected, and the four locking plates 46 are assembled on the four sleeve columns 31 in a one-to-one manner. Two vertically distributed guide rods 311 are horizontally welded on the side wall of the sleeve column 31 facing the cross center of the bottom template 11. The central axis of the guide rod 311 points to the cross center of the bottom template 11, and the locking plate 46 is horizontally slidably installed on the two guide rods 311 corresponding to the sleeve columns 31; a rectangular plug 461 is welded on the plate surface of the locking plate 46 facing the sleeve column 31 at the corresponding position; a avoidance hole 312 for the plug 461 to pass through is provided on the sleeve column 31; a socket 1121 for the plug 461 to be inserted is provided horizontally on the guide column 112; in this embodiment, when the sleeve column 31 is sleeved on the guide column 112 and the bottom plate 33 is in contact with the bottom template 11, the socket 1121 and the plug 461 are in a relative matching position.

[0046] like Figure 2 、 Figure 3 、 Figure 4 and Figure 8As shown, in the present invention, the bottom formwork 11, the internal formwork 12 and the external formwork 13 in the casting mold 1 are assembled, clamped and constrained for positioning, but no corresponding locking mechanism is provided. Therefore, during the concrete pouring and vibration process, it is easy to cause displacement and deformation of the formwork material of the casting mold 1, leakage of concrete material and defects in the concrete pouring product. Therefore, a clamping assembly 5 is also assembled on the positioning frame 3; the clamping assembly 5 includes a travel frame 51, and the travel frame 51 includes a bearing seat 511 threadedly connected to the lead screw 34, and the bottom end of the bearing seat 511 is vertically welded with four sliding rods 512 vertically slidably installed in the four sleeve columns 31 in a one-to-one correspondence; a clamping assembly is vertically rotatably installed on the bearing seat 511. The frame 52 has four pressure plates 521 evenly distributed on the circumference of the compression frame 52; four pressure plates 15 evenly distributed on the circumference and aligned with the top horizontally are welded on the internal mold frame 12 and the external mold frame 13. The four pressure plates 15 on the internal mold frame 12 are arranged centrally relative to the four casting cavities 14, and the four pressure plates 15 on the external mold frame 13 are also arranged centrally relative to the four casting cavities 14; the pressure plate 15 fixed on the internal mold frame 12 is located inside the frame, and the pressure plate 15 fixed on the external mold frame 13 is located outside the frame; a corresponding hanging plate 151 is fixed to the upper end surface of each pressure plate 15; the hanging plate 151 is L-shaped and fixed inverted, and the vertical plate portion of the hanging plate 151 is welded to the pressure plate 15. Any pressing plate 521 is cooperated with two pressure plates 15 (located on the internal mold frame 12 and the external mold frame 13 respectively) and two hanging plates 151 (located on the internal mold frame 12 and the external mold frame 13 respectively) adjacent to the casting cavity 14. When the casting mold 1 is locked, the pressing plate 521 can be pressed against the pressure plate 15. When auxiliary mold removal is performed, the hanging plate 151 can be hung on the pressing plate 521. In order to enhance the positioning effect, a pin hole 152 is provided on the horizontal plate portion of the hanging plate 151; two pin shafts 522 are provided on the upper plate surface of the pressing plate 521, which are inserted into the pin holes 152 in the two hanging plates 151 that cooperate with the internal mold frame 12 and the external mold frame 13.

[0047] The locking of the casting mold 1 can be achieved by the docking cooperation between the locking mold hanger 2 and the casting mold 1. Specifically, after the positioning frame 3 is sleeved on the four guide pillars 112 through the sleeve column 31, the four pressure plates 521 are rotated and moved between the hanging plate 151 and the corresponding pressure plate 15 by rotating the clamping frame 52. Then, by holding the ring 341 and rotating the screw 34, on the one hand, the screw 34 drives the stroke cylinder 41 to descend, so that the sliding shaft 42 and the hinge The end 43 is synchronously lowered with the stroke cylinder 41, and the hinged end 43 will synchronously drive the four locking plates 46 through the four connecting rods 45, so that the locking plates 46 are close to the sleeve columns 31 at their respective positions along the two guide rods 311, and the plug block 461 will then pass through the avoidance hole 312 and be inserted into the socket 1121. When the locking plate 46 is tightly attached to the sleeve column 31, the plug block 461 is located at the deepest position in the socket 1121, and the four locking plates 46 are aligned with the plug block 461. The four guide columns 112 are connected in pairs, thereby indirectly realizing the locking between the entire clamping hanger 2 and the bottom template 11; on the other hand, under the guidance of the four sleeve columns 31, the screw 34 drives the travel frame 51 to slide down, and the clamping frame 52 and the travel frame 51 are synchronously lowered. Before the pressure plate 521 does not contact the pressure plate 15, the plug 461 is pre-inserted into the deepest part of the socket 1121. As the screw 34 continues to rotate, the travel cylinder 41 continues to descend, causing the spring 44 to be passively compressed, and the pressure plate 521 continues to descend and is pressed on the pressure plate 15. The four pressure plates 521 are pressed on the four pressure plates 15 on the inner mold frame 12, and are synchronously pressed on the four pressure plates 15 on the outer mold frame 13, so that the inner mold frame 12 and the outer mold frame 13 are steadily pressed on the bottom template 11 through the evenly distributed downward pressure, thereby realizing the locking between the templates in the casting mold 1 on the basis of completing the matching and locking with the bottom template 11.

[0048] In addition, if Figures 1 to 12 As shown, the present invention also provides a method for manufacturing a concrete hollow formwork for a wall structural column, comprising the following steps: S1, docking the locking mold hanger 2 on the casting mold 1; under the synchronous drive of the screw 34, the locking mold hanger 2 is locked on the bottom mold plate 11 through the locking mechanism 4, and the internal mold frame 12 and the external mold frame 13 are synchronously clamped through the clamping assembly 5; thereby, the casting mold 1 is quickly locked with the help of the locking mold hanger 2.

[0049] S2. Pour concrete material required for forming the hollow formwork 6 into the four pouring cavities 14.

[0050] S3. Vibrate the concrete in the casting cavity 14. During vibration, manual vibration can be performed using a vibration pump. In order to improve the efficiency and effect of vibration, a corresponding vibration platform can also be installed. The casting mold 1 can be hoisted as a whole onto the vibration platform by a crane using the clamping mold hanger 2 for vibration operation.

[0051] S4. With the help of an existing crane and the clamping hanger 2, the casting mold 1 is lifted to the curing area.

[0052] S5. By rotating the lead screw 34, the insert 461 is withdrawn from the insertion hole 1121, and the pressure plate 521 moves upward and separates from the pressure plate 15, thereby releasing the lock and releasing the pressure. Subsequently, the clamping hanger 2 is lifted by the crane, separating it from the casting mold 1. The casting mold 1, with four hollow formwork shells 6, is then placed in the curing area for curing. The poured concrete is then cured in the curing area, allowing the hollow formwork shells 6 to solidify and set. The separated clamping hanger 2 can then be used with the next casting mold 1.

[0053] S6. After solidification and shaping, the mold clamping hanger 2 is docked with the casting mold 1 again, and with the cooperation of the mold clamping hanger 2, the internal mold frame 12 and the external mold frame 13 are lifted and separated from the hollow mold shell 6. Specifically, after the sleeve column 31 is completely fitted and docked on the guide column 112, the clamping frame 52 is rotated to rotate the pressure plate 521 and move it between the suspension plate 151 and the pressure plate 15. In this embodiment, when the pressure plate 521 is rotated to contact the vertical plate portion of the suspension plate 151, the pin shaft 522 is aligned with the pin hole 152 at the corresponding position. Subsequently, the fixed hollow mold shell 6 and the internal mold frame 12 and the external mold frame 13 can be separated vertically by a rubber hammer or other means. Then, the mold clamping hanger 2 is driven up by the crane. During the rising process, the pin shaft 522 is inserted into the pin hole 152 correspondingly. 2, and the hanging plate 151 is automatically suspended on the pressure plate 521, and the plug-in cooperation of the pin shaft 522 and the pin hole 152 improves the stability of the hanging plate 151 in synchronously lifting the internal mold frame 12 and the external mold frame 13 upward. When rising, the guide column 112 has a guiding effect on the sleeve column 31. In addition, the four pressure plates 521 are evenly distributed, and the locking mold hanger 2 is located at the center of the casting mold 1 as a whole, thereby ensuring that the internal mold frame 12 and the external mold frame 13 can be quickly lifted and separated vertically, reducing the resistance and difficulty during demolding, and effectively avoiding the demolding deformation of the internal mold frame 12 and the external mold frame 13.

[0054] S7, the four hollow formworks 6 are separated from the bottom formwork 11, and are unloaded and stored in a centralized manner. The hollow formworks 6 are stored in a centralized manner in a finished product stacking area.

[0055] It should be noted that the casting mold 1, as a forming mold for the hollow mold shell 6, needs to be maintained simultaneously with the concrete. Therefore, the casting mold 1 can be assembled in a certain quantity, and the locking hanger 2 only needs to be assembled with a certain number for rotation use.

[0056] The present invention provides a manufacturing device for concrete hollow formwork for wall structural columns. Unlike the traditional single-cavity casting frame, the casting mold 1 of the present invention adopts a single-mold multi-cavity design, which can meet the synchronous batch casting of multiple hollow formworks 6, and is provided with a locking mold hanger 2 in conjunction with the casting mold 1. Through the docking of the locking mold hanger 2, the casting mold 1 can be quickly and stably locked before casting on the basis of meeting the basic lifting and transfer requirements, and the casting mold 1 can be quickly assisted in demolding after casting and shaping; batch molding and manufacturing can be realized, and the frequency of manual repeated operations in the manufacturing process of the hollow formwork 6 is greatly reduced, the difficulty of mold assembly and demolding is reduced, the manufacturing efficiency is improved, the deformation of the mold plate is reduced, and the conversion rate and service life of the casting mold 1 are improved.
