Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, specifically to a foundation cup-shaped inner formwork that is easy to dismantle. Background Technology

[0002] A cup-shaped foundation is a common type of foundation used in building and civil engineering. It primarily supports the structure and transfers its load to the ground. A cup-shaped foundation generally consists of a lower load-bearing section and an upper cup-shaped section. The load-bearing section is typically a wide base. This design effectively distributes the load and transfers the load of the superstructure to the ground, improving the foundation's stability.

[0003] In the existing cup-shaped foundation, a template needs to be set on the inside during the pouring process to create a hollow recessed area. After pouring, the template is demolded. However, the existing template tends to stick to the concrete after pouring, making demolding difficult. Therefore, a device is needed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a basic cup-mouth inner template that is easy to demold, thus solving the problem of difficult demolding of the basic cup-mouth inner template.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a basic cup-mouth inner template that is easy to demold, including an extension plate, a connecting plate and a demolding mechanism, wherein the connecting plate is connected to the extension plate through a positioning mechanism, and a corner plate is connected to the side of the connecting plate away from the extension plate through a snap-fit ​​mechanism, wherein the extension plate, the connecting plate and the corner plate form a template;

[0006] The demolding mechanism includes a main body, a telescopic rod, and a disassembly block. The telescopic rod is fixedly connected to both sides of the main body. A connecting block is rotatably provided at one end of the telescopic rod. An extension block is threadedly connected to one end of the connecting block. The disassembly block is threadedly connected to one end of the extension block.

[0007] The disassembly block is detachably connected to the back of the expansion plate via a connecting mechanism.

[0008] Optionally, the snap-fit ​​mechanism includes a connecting groove and a connecting buckle. The connecting groove is formed on both sides of the corner plate, and the connecting buckle is fixedly connected to one side of the connecting plate. The connecting buckle is slidably connected to the connecting groove.

[0009] Optionally, the positioning mechanism includes a positioning groove and a positioning block. The positioning groove is formed on both sides of the expansion plate, and the positioning block is C-shaped. The positioning block and the positioning groove are detachably connected.

[0010] Optionally, sealing gaskets are provided on both sides of the expansion plate to seal the gap between adjacent expansion plates.

[0011] Optionally, the connecting mechanism includes a pull ring and a hook, the pull ring being fixedly connected to the back of the extension plate, the hook being located at one end of the disassembly block, and the pull ring and the hook being detachably connected.

[0012] Optionally, a support rod is detachably connected to the lower end of the back of the extension plate, and one end of the support rod is connected to a support plate via a pivot to improve the stability of the pouring process.

[0013] Optionally, the bottom of the support plate is provided with ground nails to improve stability.

[0014] This utility model provides a basic cup-mouth inner template that is easy to demold, and has the following beneficial effects:

[0015] This utility model provides a basic cup-shaped inner formwork that is easy to dismantle. Through the coordinated arrangement of extension plates, connecting plates, and corner plates, a complete formwork surface can be divided into multiple small planes. During demolding, the small planes are demolded one by one, reducing the difficulty of demolding.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a basic cup mouth inner template that is easy to demold, including an extension plate 1, a connecting plate 2 and a demolding mechanism. The connecting plate 2 is connected to the extension plate 1 through a positioning mechanism. The side of the connecting plate 2 away from the extension plate 1 is connected to a corner plate 3 through a snap-fit ​​mechanism. The extension plate 1, the connecting plate 2 and the corner plate 3 form a template.

[0025] The demolding mechanism includes a main body 4, a telescopic rod 5, and a disassembly block 6. The telescopic rod 5 is fixedly connected to both sides of the main body 4. A connecting block 7 is rotatably provided at one end of the telescopic rod 5. An extension block 8 is threadedly connected to one end of the connecting block 7. The disassembly block 6 is threadedly connected to one end of the extension block 8.

[0026] The extension plates 1 can be spliced ​​together. The connecting plates 2 can be installed on the outer side of the extension plates 1 at both ends and connected by the corner plates 3 to form an inner template, providing support during the pouring process. The main body 4 is equipped with a hook, which can be hoisted into the inner template during use. The telescopic rod 5 can be extended or shortened, thereby driving the connecting block 7 at one end to move. The connecting block 7 is threaded with an extension block 8, which can extend the overall length according to the actual template length, so that the disassembly block 6 at one end can be connected to the extension plate 1. During pouring, multiple main bodies 4 can be used, and the disassembly blocks 6 on both sides of the main body 4 can support the extension plates 1. The corner plates 3 have a variety of different angles. In actual use, the appropriate angle of the corner plate 3 can be selected according to different situations to splice out the required templates such as rectangles or inverted trapezoids.

[0027] In this embodiment, as a preferred solution, the snap-fit ​​mechanism includes a connecting groove 9 and a connecting buckle 10. The connecting groove 9 is opened on both sides of the corner plate 3, and the connecting buckle 10 is fixedly connected to one side of the connecting plate 2. The connecting buckle 10 is slidably connected to the connecting groove 9.

[0028] The connecting buckle 10 can slide into the connecting groove 9 from top to bottom. Both the connecting groove 9 and the connecting buckle 10 are trapezoidal. After the two are connected, the horizontal movement direction of the two can be restricted, so that the two are fixed together.

[0029] In this embodiment, as a preferred option, the positioning mechanism includes a positioning groove 11 and a positioning block 12. The positioning groove 11 is formed on both sides of the expansion plate 1, and the positioning block 12 is C-shaped. The positioning block 12 is detachably connected to the positioning groove 11.

[0030] The positioning groove 11 on one side is L-shaped, and can form a C-shape after the expansion plates 1 are spliced ​​together, so that the positioning block 12 can be inserted into the positioning groove 11, thereby splicing the expansion plates 1 on both sides together. During use, the number of expansion plates 1 can be adjusted according to the required length of the inner template.

[0031] In this embodiment, as a preferred option, sealing gaskets 13 are provided on both sides of the expansion plate 1, and the sealing gaskets 13 are used to seal the gaps between adjacent expansion plates 1.

[0032] After the expansion plates 1 are spliced ​​together, the sealing gasket 13 can fill the gaps between the expansion plates 1, prevent cement mortar from flowing into the gaps, reduce the contact area between cement and expansion plates 1, and thus reduce the difficulty of demolding.

[0033] The disassembly block 6 is detachably connected to the back of the expansion plate 1 via a connecting mechanism.

[0034] In this embodiment, as a preferred option, the connecting mechanism includes a pull ring 14 and a pull hook 15. The pull ring 14 is fixedly connected to the back of the extension plate 1, and the pull hook 15 is located at one end of the disassembly block 6. The pull ring 14 and the pull hook 15 are detachably connected.

[0035] The hook 15 can be engaged with the pull ring 14 to fix the disassembly block 6 on the pull ring 14. During the retraction of the telescopic rod 5, the telescopic rod 5 pulls the connecting block 7 connected at one end to move. The connecting block 7 drives the extension block 8 to move, which in turn drives the disassembly block 6 to move. The disassembly block 6 is connected to the pull ring 14, so that when the disassembly block 6 moves, it can pull the pull ring 14 to move, thus separating the extension plate 1 from the cast cup-shaped foundation, making it easier to remove the inner template.

[0036] In this embodiment, as a preferred option, a support rod 16 is detachably connected to the lower end of the back of the extension plate 1. One end of the support rod 16 is connected to a support plate 17 via a pivot to improve the stability of the pouring process. A ground nail 18 is provided at the bottom of the support plate 17 to improve stability.

[0037] The support rod 16 is also connected to the extension plate 1 through a connecting structure. During the pouring process, the support rod 16, together with the support plate 17, supports the back of the extension plate 1 to prevent the extension plate 1 from tilting. The ground nail 18 is detachably connected to the bottom of the support plate 17. At the position where the ground nail 18 can be used, the ground nail 18 can be driven into the ground to improve the stability of the support.

[0038] In this invention, the working steps of the device are as follows:

[0039] 1. When using, select an appropriate number of extension plates 1 according to the length of the inner template, fix the adjacent extension plates 1 with the connecting joint, install the connecting plate 2 on both sides of the extension plate 1, and then install the corner plate 3 to enclose the three into the inner template.

[0040] 2. Place the inner and outer templates together and pour the concrete between them. After the concrete pouring is completed, place the main body 4 in the inner template, adjust the length of the telescopic rod 5, connect the disassembly blocks 6 at both ends to the pull rings 14 on the two side extension plates 1 respectively, remove the connecting buckles 10 at the connection position of the extension plates 1, and control the telescopic rod 5 to retract after removal, so as to separate one end of the extension plate 1 from the poured cement.

[0041] 3. After separating one of the expansion plates 1, start demolding from both sides of this expansion plate 1, and remove the surrounding expansion plates 1 and corner plates 3 in sequence to reduce the difficulty of demolding.
