Description

TECHNICAL FIELD

[0001] The utility model relates to the field of concrete pouring mould, especially to a pouring mould for concrete foundation pile. BACKGROUND

[0002] In construction engineering, the pouring of concrete foundation pile is a crucial link, which is directly related to the structural strength and stability of the foundation pile. However, in the traditional pouring process of foundation pile, especially for the installation and positioning of the embedded part at the end of the foundation pile, there are a series of technical problems.

[0003] The existing embedded part at the end of the foundation pile often needs to use a large number of wooden boards for positioning and supporting during pouring. These wooden boards are not only complicated to install, but also often cannot be reused after pouring, causing great material waste.

[0004] More specifically, using wooden boards as pouring moulds has the following disadvantages:

[0005] Not reusable: wooden boards are easily squeezed and eroded by concrete during pouring, leading to deformation and damage, so they cannot be reused, increasing construction costs.

[0006] Large consumption of materials: a large number of new wooden boards are needed for each pouring, which not only increases material costs but also causes unnecessary burden on the environment.

[0007] Therefore, it is necessary to provide a new pouring mould for concrete foundation pile to solve the above technical problems. SUMMARY

[0008] To solve the above technical problems, the utility model provides a pouring mould for concrete foundation pile.

[0009] The pouring mould for concrete foundation pile provided by the utility model comprises a frame, a support leg, a connecting piece and a fixing ring. The frame is placed above a column body. The inside of the frame is provided with an extensible corrugated pipe. The bottom end of the frame is provided with support legs at equal intervals. The bottom end of each support leg is provided with an L-shaped supporting leg. The inside of the frame is symmetrically provided with connecting pieces. The end portions of the two connecting pieces are fixedly connected by threads. The top end of the corrugated pipe is fixedly connected with a fixing ring. The bottom end of the corrugated pipe is fixedly connected with a flexible ring.

[0010] Preferably, a sliding groove is formed at the bottom end of the support leg. A fixed threaded rod is rotatably connected inside the sliding groove. One end of the L-shaped supporting leg is slidably connected with the sliding groove and threadedly connected with the fixed threaded rod.

[0011] Preferably, a height threaded rod is rotatably connected inside the frame. One end of the height threaded rod is threadedly connected with the fixing ring. A scale line is formed on one side of the frame.

[0012] Preferably, the bottom end of the frame is slidingly connected with a connecting ring, the inside of the connecting ring is equidistantly fixedly connected with an extension block, the top end of the flexible ring is equidistantly fixedly connected with a connecting rod, one end of the connecting rod is slidingly connected with the extension block, the outer wall of the connecting rod is sleeved with a spring, one end of the spring is fixedly connected with one side of the extension block, the other end of the spring is fixedly connected with one side of the flexible ring, and the inside of the connecting ring is equidistantly screwedly connected with a bolt corresponding to the frame.

[0013] Preferably, the top end of the fixed threaded rod and the height threaded rod is fixedly connected with a hexagonal block matched with a hexagonal wrench.

[0014] Preferably, the top end of the leg is fixedly connected with a bubble level.

[0015] Preferably, the connecting piece is a semicircular flexible steel plate.

[0016] Compared with the related art, the pouring mold for concrete foundation piles has the following beneficial effects:

[0017] Improve the pouring precision and stability:

[0018] The retractable bellows inside the mold can flexibly adapt to the requirements of foundation piles of different diameters and shapes, ensuring accurate alignment during pouring.

[0019] The connecting piece inside the frame is a semicircular flexible steel plate, which has good rigidity and plasticity, further improving the stability and adaptability of the mold.

[0020] The cooperation of the spring and the flexible ring enables the mold to better fit the pouring surface, reduces concrete leakage, and improves pouring quality.

[0021] Enhance the reusability of the mold:

[0022] The main structure of the mold is made of a solid and durable material, which can withstand the huge pressure during pouring and is not easy to deform or damage.

[0023] The key components such as bellows, connecting pieces, and springs can be disassembled and replaced, prolonging the service life of the mold and reducing maintenance costs.

[0024] Reduce material costs and environmental benefits:

[0025] Compared with traditional wooden molds, the mold proposed by the application has higher durability and reusability, significantly reducing material costs.

[0026] At the same time, since the use of wood is reduced, the consumption of natural resources and the destruction of the environment are also reduced, in line with the concept of sustainable development.

[0027] Improve work efficiency and convenience:

[0028] The height and stability of the mold can be precisely adjusted through the adjusting function of the supporting legs and the L-shaped supporting feet, so as to adapt to different terrains and pouring requirements.

[0029] The scale line on one side of the frame and the height threaded rod are designed to enable the operator to conveniently measure and adjust the pouring height, thereby improving the work efficiency.

[0030] The hexagonal block at the top end of the fixed threaded rod and the height threaded rod is designed to facilitate the rotation and adjustment by using an internal hexagonal wrench, and the operation is more convenient. BRIEF DESCRIPTION OF DRAWINGS

[0038] It should be noted that the bottom of frame 1 is equidistantly installed with support legs 4, and the bottom of the support legs is provided with L-shaped feet 5; the L-shaped feet are connected with the support legs through the sliding slots 9 and are fixed by the fixed threaded rods 10.

[0039] By rotating the fixed threaded rods, the position of the L-shaped feet in the sliding slots can be adjusted, thereby changing the overall height and stability of the mold. This design allows the mold to adapt to different terrains and pouring requirements, ensuring smooth and accurate pouring.

[0040] Please refer to Figures 2-3 The bottom of frame 1 is slidably connected with a connecting ring 12, the inside of the connecting ring 12 is equidistantly fixedly connected with extension blocks 13, the top of the flexible ring 8 is equidistantly fixedly connected with connecting rods 14, one end of the connecting rods 14 is slidably connected with the extension blocks 13, the outer wall of the connecting rods 14 is sleeved with springs 15, one end of the springs 15 is fixedly connected with one side of the extension blocks 13, the other end of the springs 15 is fixedly connected with one side of the flexible ring 8, the inside of the connecting ring 12 is equidistantly threadedly connected with bolts corresponding to the frame 1.

[0041] It should be noted that the bottom of frame 1 is slidably connected with a connecting ring 12, and the inside of the connecting ring is equidistantly fixed with extension blocks 13; the top of the flexible ring 8 is equidistantly fixed with connecting rods 14, which are slidably connected with the extension blocks.

[0042] The outer wall of the connecting rods 14 is sleeved with springs 15, one end of the springs is fixedly connected with one side of the extension blocks 13, and the other end is fixedly connected with the corresponding position of the connecting rods 14 or the flexible ring 8. The specific connection position may vary depending on the design, but the purpose is to allow the springs to exert a sticking effect.

[0043] When the mold is placed on the pouring surface, due to the unevenness of the ground or the change of the pouring surface, the flexible ring 8 may be extruded or stretched to different degrees; at this time, the elastic action of the spring 15 will play a key role, which can provide corresponding reaction force according to the deformation of the flexible ring 8, so that the flexible ring is better fitted to the pouring surface;

[0044] This design not only enhances the close contact between the mold and the pouring surface, reduces the possibility of concrete leakage from the gap between the mold and the pouring surface, but also can absorb the impact force generated during pouring to a certain extent, protecting the mold and the pouring surface from damage.

[0045] The working principle of the pouring mold for concrete foundation pile provided by the utility model is as follows:

[0046] The combination of the frame and the bellows:

[0047] The frame 1 is placed above the column 2 to be poured as the main structure of the mold; the inside of the frame is designed with retractable bellows 3, and the flexible characteristics of the bellows can adapt to the requirements of foundation piles of different diameters and shapes;

[0048] The top end of the bellows is connected to the frame 1 through the fixing ring 7, and the bottom end is in contact with the pouring surface through the flexible ring 8; this design not only ensures the stability of the mold, but also allows fine adjustment during pouring to adapt to possible changes;

[0049] Adjusting function of the leg and the L-shaped foot:

[0050] The bottom end of the frame 1 is equidistantly installed with the leg 4, and the bottom end of the leg is provided with the L-shaped foot 5; the L-shaped foot is connected to the leg through the sliding groove 9 and fixed through the fixed threaded rod 10;

[0051] By rotating the fixed threaded rod, the position of the L-shaped foot in the sliding groove can be adjusted, thereby changing the overall height and stability of the mold; this design makes the mold adapt to different terrains and pouring requirements, ensuring smooth and accurate pouring;

[0052] Fixing and adjusting of the connecting piece:

[0053] The frame 1 is symmetrically installed with the connecting piece 6 inside, which is a semicircular flexible steel plate with good rigidity and plasticity;

[0054] The end of the connecting piece is fixedly connected through threads, which can conveniently adjust the distance between the connecting pieces to adapt to foundation piles of different diameters; at the same time, the flexible characteristics of the connecting piece can also absorb the impact force during pouring to a certain extent, protecting the foundation pile from damage;

[0055] Height threaded rod and scale line auxiliary positioning:

[0056] A height threaded rod 11 is rotatably connected inside the frame 1 and is threadedly connected to one end of the fixed ring 7; by rotating the height threaded rod, the height of the corrugated pipe can be accurately adjusted, thereby achieving precise control over the pouring height;

[0057] The frame is also provided with scale lines on one side to assist in measuring and adjusting the position of the height threaded rod, ensuring the accuracy and consistency of the pouring height;

[0058] Buffering effect of the connecting ring and the spring:

[0059] The bottom end of the frame 1 is slidingly connected with a connecting ring 12, and the connecting ring is equidistantly fixed with extension blocks 13 inside; the top end of the flexible ring 8 is equidistantly fixed with connecting rods 14, which are slidingly connected with the extension blocks;

[0060] The outer wall of the connecting rod 14 is sleeved with a spring 15, one end of which is fixedly connected with one side of the extension block 13, and the other end is fixedly connected with the corresponding position of the connecting rod 14 or the flexible ring 8. The specific connection position may vary according to the design, but the purpose is to enable the spring to exert a close-fit effect;

[0061] When the mold is placed on the pouring surface, due to the unevenness of the ground or the change of the pouring surface, the flexible ring 8 may be subjected to different degrees of extrusion or stretching; at this time, the elastic effect of the spring 15 will play a key role, which can provide corresponding counterforce according to the deformation of the flexible ring 8, so that the flexible ring can better fit the pouring surface;

[0062] This design not only enhances the close contact between the mold and the pouring surface, reduces the possibility of concrete leakage from the gap between the mold and the pouring surface, but also can absorb the impact force generated during pouring to a certain extent, protecting the mold and the pouring surface from damage;

[0063] Use of hexagonal blocks with an internal hexagonal wrench:

[0064] The top end of the fixed threaded rod 10 and the height threaded rod is fixed with a hexagonal block that is compatible with an internal hexagonal wrench; this design allows the operator to conveniently use the internal hexagonal wrench to rotate and adjust the threaded rod, improving work efficiency and operational convenience;

[0065] Auxiliary monitoring of the bubble level:

[0066] The top end of each leg is fixed with a bubble level for monitoring the levelness and stability of the mold; before pouring, the operator can observe the indication of the bubble level to adjust and calibrate the mold, ensuring the smoothness and accuracy of the pouring process.

[0067] The above merely illustrates the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which are made by using the content of the present application specification and drawings, are also included in the patent protection scope of the present application.
