Description

Technical Field

[0001] This invention relates to the field of building construction engineering, and specifically to a demolding device for precast components and its usage method. Background Technology

[0002] In building construction, round or square columns are usually used as support columns. Currently, the processing of support columns usually involves using prefabricated components made of finished steel molds. Steel molds made in the factory are selected according to the size of the support column, and then the support column is formed by casting and processing, and then transported to the construction site for reinforcement construction.

[0003] In the existing technology, when separating the precast component from the mold after it has been poured, it is difficult to separate it directly because the inside of the mold and the support column will stick together. If it is forcibly removed, the support column can easily be damaged, requiring re-pouring or repair. This not only increases the workload, but also risks reducing the strength of the precast component. Summary of the Invention

[0039] This invention provides a demolding device and method for precast components, solving the problem that in existing methods, when separating precast components from the mold after pouring, direct separation is difficult because the inner side of the mold adheres to the support column. Forcibly removing the component easily damages the support column, requiring re-pouring or repair, increasing workload and risking a reduction in the strength of the precast component. The new device uses a support mechanism to support the mold, forming a pouring space. Concrete is poured into this space to form the support column. After pouring, the bottom plate of the mold is separated. A rotating mechanism drives a cutting mechanism to separate the support column from the mold side plate. Simultaneously, a hammering mechanism further separates the support column from the mold side plate, achieving separation of the support column without damage.

[0040] The present invention will be further described below with reference to specific embodiments.

[0041] See Figure 1 The image shows a front view of the demolding device for the prefabricated components of the present invention.

[0042] like Figure 1As shown, the demolding device for precast components of the present invention includes: a cylinder 215, a support mechanism 31, a cutting mechanism 41, and a rotating mechanism 51. The interior of the cylinder 215 of the demolding device forms a space to accommodate a mold 21. The mold 21 is placed inside the cylinder 215 and includes a mold base plate 211 and several mold side plates 212. The side plates 212 are joined in pairs and, together with the mold base plate 211, form a casting space for a support column. The bottom of the mold 21 is separable, making it easier to cut the mold 21 after the support column casting is completed. The support mechanism is mounted on the cylinder 215 and positions the mold inside the cylinder 215. The rotating mechanism 51 slides on the cylinder 215 and can slide horizontally relative to the cylinder 215. The cutting mechanism 41 is located on the outside of the mold 21, corresponding to the rotating mechanism. The cutting mechanism 41 is equipped with a cutting wire 414 that can be adjusted up and down. The cutting wire 414 can be attached to the inner side of the mold 21. When it is adjusted up and down, it works with the back and forth rotation of the rotating mechanism 51 to cut and separate the precast component from the mold 21. The cutting mechanism 41 and the rotating mechanism 51 are fixedly connected. The rotating mechanism 51 drives the cutting mechanism 41 to rotate around the mold 21. The cutting mechanism 41 cuts and separates the support column that has been cast in the mold 21 from the mold 21.

[0043] In a preferred embodiment of the demolding device for precast components of the present invention, a support column base plate 213 is further provided on the mold base plate 211. The outer diameter of the support column base plate 213 is smaller than the inner diameter of the mold side plate 212. The support column base plate 213 is located at the bottom of the casting space, and a plurality of steel bar grooves 214 are provided on the support column base plate 213. A plurality of steel bars are vertically inserted into the steel bar grooves 214 to improve the strength of the cast support column.

[0044] See Figure 2 This image shows a top view of the cutting mechanism 41 in the demolding device for the precast component of the present invention. (Combined with...) Figure 1 and Figure 2 As shown, specifically, the support mechanism 31 includes a first U-shaped rod 312 with both ends embedded and passing through the cylinder 215. One end of the first U-shaped rod 312 is connected to a pull rope 313, and the other end of the pull rope 313 is connected to the bottom plate of the mold. The pull rope 313 is in a tensioned state. The other end of the first U-shaped rod 312 is fixedly connected to the side plate of the mold. A second spring is provided on the first U-shaped rod 312 between the side plate of the mold and the cylinder 215. The lower end of the first U-shaped rod 312 is supported on the cylinder 215. Due to the setting of the pull rope 313, the outward movement of the first U-shaped rod 312 can be restricted. Since the upper end supports the mold, the possibility of the mold moving outward during pouring is prevented, thus avoiding concrete leakage.

[0045] Furthermore, the support mechanism 31 also includes a hydraulic rod 311 vertically installed inside the cylinder 215. The fixed end of the hydraulic rod 311 is erected on the cylinder 215, and the movable end of the hydraulic rod 311 is fixedly connected to the mold base plate 211. The hydraulic rod 311 supports the mold in the air. When the hydraulic rod 311 retracts, the mold base plate 211 separates from the mold side plate 212, so that the support column inside the mold is subjected to gravity and is more easily separated from the mold side plate.

[0046] At the same time, the hydraulic rod 311 retracts, and after the mold base plate is lowered, the pull rope 313 will loosen, releasing the restriction on the outward movement of the first U-shaped rod 312. Consequently, the mold side plate will also move outward with the first U-shaped rod 312, which is more conducive to subsequent cutting and hammering, making it easier to separate the support column from the mold.

[0047] See Figure 3 This image shows a top view of the striking mechanism and rotating mechanism in the demolding device for the precast component of the present invention. Furthermore, in conjunction with... Figure 1 and Figure 3 As shown, the upper end of the cylinder 215 in the demolding device of the precast component of the present invention is provided with an annular groove, and the rotating mechanism 51 includes: a ring 514 adapted to the annular groove, one end of the ring 514 extending out of the annular groove to form a connecting part, and the cutting mechanism is connected to the connecting part so that the cutting mechanism rotates with the rotating mechanism.

[0048] Specifically, the driving device of the rotating mechanism includes: a horizontal plate 511, a first motor 512, and a first gear 513. The horizontal plate 511 is fixedly connected to the inner side of the cylinder 215. The first motor 512 is mounted on the horizontal plate 511, and its output end rotates on a horizontal plane. The first gear 513 is mounted on the rotating shaft of the first motor 512. The connecting part of the ring 514 has teeth that mate with the first gear 513. The first gear 513 is gear-connected to the ring 514. The rotation of the first motor 512 drives the rotation of the first gear 513, which in turn drives the ring 514 to slide horizontally in the ring groove, ultimately driving the cutting mechanism 41 to rotate around the mold 21, causing the mold 21 to be cut and separated from the support column.

[0049] Furthermore, the cutting mechanism 41 of the demolding device for the precast component of the present invention includes a second U-shaped rod 411 fixedly connected to the connecting part of the ring 514. The second U-shaped rod 411 is vertically arranged along the length direction. The upper and lower ends of the second U-shaped rod 411 are respectively rotatably connected to a first winding roller 412 and a second winding roller 413. One end of the cutting wire 414 is wound around the first winding roller 412, and the other end of the cutting wire 414 passes around the inner side of the mold side plate 212 and is wound around the second winding roller 413. The cutting wire 414 is in a tensioned state. After the mold 21 is cast, the cutting wire 414 is located between the mold 21 and the support column to separate the mold 21 from the support column.

[0050] In another preferred embodiment of the demolding device for the precast component of the present invention, a guide roller 415 is further provided on the side of the first winding roller 412 and the second winding roller 413 near the mold side plate 212, and the cutting wire 414 is wound on the guide roller 415. Preferably, the first winding roller 412 and the second winding roller 413 are controlled by a second motor 416.

[0051] See Figure 4 This shows a front view of the mold 21 in the demolding device for the prefabricated component of the present invention. Combined with... Figure 1 and Figure 4 As shown, in a preferred embodiment of the demolding device for the precast component of the present invention, a hammering mechanism 61 is further included. The hammering mechanism 61 is disposed on the side of the mold 21 corresponding to the cutting mechanism 41, making it easier to separate the mold 21 from the support column.

[0052] Furthermore, the knocking mechanism 61 of the demolding device for the precast component of the present invention includes: a guide rod 613, a limiting head 614, a spring 615, and an arc plate 616.

[0053] The guide rod 613 is fixed to the outside of the mold side plate 212. A limiting head 614 is provided at the end of the guide rod 613 away from the mold side plate 212. An arc-shaped plate 616 has a circular hole corresponding to the diameter of the guide rod 613. The arc-shaped plate 616 slides on the guide rod 613, and a spring 615 is wound around the guide rod 613. The spring 615 is wound between the limiting head arc-shaped plate 616 and the mold side plate 212. Several striking blocks 619 are horizontally spaced on the inner side of the arc-shaped plate 616, and several abutting blocks 618 are horizontally spaced on the outer side of the arc-shaped plate. The roller seat 611 is fixed to the... Inside the two U-shaped rods, the roller shaft on the roller seat 611 is horizontally arranged, so that the roller 612 set on the roller seat 611 rotates in the horizontal direction. The roller 612 is rotatably connected to the roller seat 611. The contact block 618 can press against the roller 612. As the rotating mechanism 51 rotates, the roller 612 and the contact block 618 on the outer side of the arc plate 616 are pressed and released, which drives the protrusion on the inner side of the arc plate 616 to slide inward against the mold side plate 212. The striking block 619 strikes the mold side plate to achieve better separation of the mold 21 from the support column.

[0054] The following description, in conjunction with the accompanying drawings, further illustrates the method of using the demolding device for prefabricated components of the present invention.

[0055] The support mechanism 31 raises the bottom of the mold 21 to a position where the mold 21 forms a pouring space. The pull rope 313 is taut, and concrete is poured into the pouring space to form a support column. After the support column is poured, the support mechanism 31 is retracted to lower the bottom height of the mold 21, separating it from the side of the mold 21. The second motor 416, which controls the first winding roller 412 and the second winding roller 413, is started, causing the first winding roller 412 and the second winding roller 413 to alternately tighten and loosen, causing the cutting wire 414 to slide up and down. The first motor 512 is then started, causing the first motor 512 to rotate 50 degrees forward and backward repeatedly, causing the teeth on the first gear 513 to mesh back and forth with the teeth on the ring 514. This causes the ring 514 to drive the cutting mechanism 41 to deflect synchronously, causing the cutting wire 414 to synchronously adhere to the inside of the mold side plate 212. The sidewall slides, effectively cutting the connection between the support column and the inner sidewall of the mold 21. As the ring 514 drives the second U-shaped rod 411 to rotate, the roller 612 of the striking mechanism 61 presses against multiple contact blocks 618. With the spring 615, the arc plate 616 slides repeatedly on the guide rod 613, causing the striking block 619 on the inner side of the arc plate 616 to collide with the outer side of the mold side plate 212, striking the mold side plate 212. This causes vibration between the mold side plate 212 and the support column, accelerating the separation of the support column from the mold 21. At the same time, it also allows the uncut area of ​​the cutting wire 414 to be separated by vibration, effectively preventing damage to the support column. The support column falls to the bottom of the mold 21, making it convenient for workers to remove the support column from the cylinder 215.

[0056] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description.
