Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a cast-in-place formwork for piers of various sizes. Background Technology

[0002] The reference patent title is: A Precast Pier Formwork Device (Authorization Announcement No.: CN213226888U, Authorization Announcement Date: 2021.05.18). The support is driven by a support drive mechanism to move to the already tied pier reinforcement. Then, the folding clamping mechanism on the support is activated, and the two supports clamp and fix the pier reinforcement through the folding clamping structure. Then, concrete is poured on the fixed pier reinforcement to support the pier. When the concrete strength of the pier reaches the standard, the folding clamping mechanism is disengaged from the pier. Then, the support drive mechanism drives the support to move longitudinally to the next work position, thereby realizing sequential cyclic operation, realizing automatic transfer, improving construction efficiency, and ensuring the accuracy of the formwork.

[0003] Based on the above-mentioned documents, the traditional method of casting cement piers mainly uses two semi-circular templates that are fastened together with bolts. This method forms the template for casting cement piers by connecting the two template blocks with bolts. However, when using this type of template, the template size is fixed and cannot be flexibly disassembled, making it impossible to cast piers of different heights according to the site conditions, resulting in poor practicality. Therefore, this utility model provides a pier casting template applicable to piers of multiple sizes. Utility Model Content

[0027] The snap-fit ​​component 72 is located inside the connecting block 712.

[0028] The connecting block 712 is also installed on the surface of the template 6 and is located below its surface.

[0029] The bottom of the base template 5 is equipped with an adapter block, the surface of the connecting bolt 4 is connected to the internal thread of the adapter block, and the top of the movable plate 3 is provided with an adapter groove that matches the adapter block.

[0030] In this embodiment, the snap-fit ​​assembly 72 includes a snap-fit ​​rod 721 that is slidably installed inside the connecting block 712. One end of the snap-fit ​​rod 721 is snapped into the inner surface of the snap-fit ​​groove 715, and the other end of the snap-fit ​​rod 721 is fixedly connected to a snap-fit ​​spring 722. The other end of the snap-fit ​​spring 722 is fixedly connected to the inner wall of the connecting block 712.

[0031] One end of the locking rod 721 is an arc-shaped end, and the locking groove 715 is an arc-shaped groove. When the operator forcefully turns the rotating rod 713, the locking rod 721 can slide out of the locking groove 715.

[0032] In this embodiment, the top of the base template 5 is provided with an installation groove 8, and the bottom of the mounting template 6 is provided with an installation plate 9. The surface of the installation plate 9 is slidably connected to the inner surface of the installation groove 8. Multiple sets of installation blocks 10 are installed on the surface of the installation plate 9. The surface of the installation block 10 is slidably connected to the inner surface of the installation groove 8. The internal thread of the installation block 10 is connected to an installation bolt 11, and the surface of the installation bolt 11 is threadedly connected to the top of the base template 5.

[0033] By incorporating the splicing mechanism 7, the elasticity of the snap-fit ​​spring 722 allows for rapid splicing of one end of the snap-fit ​​rod 721 with the inner surface of the snap-fit ​​groove 715. Furthermore, with the adaptation of the mounting groove 8 and the mounting plate 9, rapid splicing of the base template 5 and the additional template 6 can be achieved. Additionally, by incorporating multiple sets of mounting bolts 11 and mounting blocks 10, the stability of the additional template 6 after splicing can be further improved. By flexibly installing multiple sets of additional templates 6, flexible casting of piers of different heights can be achieved.

[0034] In this embodiment, the adjustment assembly 2 includes an adjustment motor 21 installed on one side of the base plate 1. One end of the output shaft of the adjustment motor 21 is fixedly connected to a bidirectional lead screw 22 via a coupling. A sliding block 23 is threadedly connected to the surface of the bidirectional lead screw 22. The top of the sliding block 23 is fixedly connected to the bottom of the moving plate 3.

[0035] The regulating motor 21 is a three-phase asynchronous motor and is connected to an external circuit via wires;

[0036] The bidirectional lead screw 22 is rotatably connected to the inside of the base plate 1.

[0037] In this embodiment, a sliding groove 12 is provided on the top of the base plate 1, and the inner surface of the sliding groove 12 is slidably connected to the surface of the sliding block 23.

[0038] The sliding groove 12 is used to limit the sliding of the sliding block 23.

[0039] In this embodiment, a symmetrical limiting slide rail 13 is installed on the top of the base plate 1, and the surface of the limiting slide rail 13 is slidably connected to the interior of the moving plate 3.

[0040] The limiting slide rail 13 is used to limit the sliding of the moving plate 3.

[0041] By starting the adjusting motor 21, the bidirectional lead screw 22 is driven to rotate. The rotation of the bidirectional lead screw 22 causes the sliding block 23 to slide on the inner surface of the sliding groove 12, thereby allowing the sliding blocks 23, the moving plate 3, and the base template 5 on both sides to slide synchronously to the opposite side, realizing the splicing of the two sets of base templates 5. Subsequently, the mounting plate 9 and mounting block 10 at the bottom of the added template 6 are matched with the mounting groove 8 at the top of the base template 5. By setting the adjusting component 2, the distance between the moving plates 3 on both sides and the base template 5 can be flexibly adjusted, so that the two sets of base templates 5 can be quickly spliced ​​and disassembled. Furthermore, different sizes of base templates 5 can be installed through the groove at the top of the moving plate 3 and the connecting bolt 4, thereby casting piers of different sizes and improving the practicality of the device.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] During operation, firstly, the two sets of base templates 5 are installed on top of the two sets of movable plates 3 using connecting bolts 4. Then, the adjusting motor 21 is started to drive the bidirectional lead screw 22 to rotate. The rotation of the bidirectional lead screw 22 causes the sliding block 23 to slide on the inner surface of the sliding groove 12, thereby causing the sliding blocks 23, movable plates 3, and base templates 5 on both sides to slide synchronously to the opposite side, realizing the splicing of the two sets of base templates 5. Subsequently, the mounting plate 9 and mounting block 10 at the bottom of the additional template 6 are fitted with the mounting groove 8 at the top of the base template 5, and the splicing block 714 installed on the surface of the rotating rod 713 is rotated by rotating the rotating rod 713. Inside the connecting block 712, the surface of the splicing block 714 is in contact with one end of the snap-fit ​​rod 721, thus squeezing the snap-fit ​​rods 721 on both sides into the interior of the connecting block 712. When the snap-fit ​​rod 721 slides to the snap-fit ​​groove 715, under the elastic drive of the snap-fit ​​spring 722, one end of the snap-fit ​​rod 721 will be snapped with the inner surface of the snap-fit ​​groove 715. Subsequently, by continuously adding, piers of different heights are cast. Finally, the base template 5 and the added template 6 are reinforced by multiple sets of mounting bolts 11 and nuts. Finally, the pier is cast and formed through the groove of the topmost added template 6.
