Description

Technical Field

[0001] This utility model relates to shaping molds, and in particular to a modular shaping mold for quick assembly and disassembly of precast pipe piles. Background Technology

[0002] During the construction process using old piles, many pile heads are damaged and need to be spliced ​​to the design elevation. The manual erection of formwork requires the use of curved formwork with steel straps for tightening, which is inefficient.

[0003] Chinese patent CN222745032U discloses a “pile splicing auxiliary device”, which includes an arc-shaped steel plate. Arc-shaped clamps are fixedly installed on the top and bottom of the arc-shaped steel plate. An arc-shaped clamp is provided on one side of each arc-shaped clamp. A pair of fastening bolts are threadedly connected between the arc-shaped clamps. This patent is applicable to welding between precast pipe pile sections and is a tool used to assist in fixing the upper and lower pipe sections. It is not suitable for precast pipe piles. It is a tool-type fixed template system for splicing precast pipe piles after removing damaged pile heads and casting in place. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a modular mold for quick assembly and disassembly of precast pipe piles that can improve formwork efficiency and is easy to adjust.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model discloses a quick-assembly and disassembly modular forming mold for splicing precast pipe piles, comprising multiple mold sections stacked vertically and connected by a connecting structure. Each mold section includes a ring-shaped steel forming mold composed of two semi-circular steel forming molds. Bolted flanges are provided at the joint of the two semi-circular steel forming molds. The two semi-circular steel forming molds are fixedly connected by bolts passing through multiple bolt holes on the bolted flanges. Multiple stiffening plates are provided on the outer wall of the ring-shaped steel forming mold. Multiple reserved connecting parts are evenly connected on the outer wall of the ring-shaped steel forming mold along the same circumferential direction. The multiple reserved connecting parts on the topmost mold section of the stacked mold are respectively connected to corresponding diagonal bracing members. An upper connecting part is rotatably connected to the upper end of each diagonal bracing member. Each upper connecting part and the corresponding reserved connecting part are fixedly connected by bolts. The lower end of each diagonal bracing member is inserted into the soil to form a stable support system.

[0007] The beneficial effects of this utility model are:

[0008] 1. Set up modular connecting end plates to connect the upper and lower modular shaping molds into a whole.

[0009] 2. Uniformly distributed stiffening plates enhance the rigidity of the formwork.

[0010] 3. The modular structure allows for adjustment of modules according to the length of the splice.

[0011] 4. The use of this mold improves mold efficiency and effectively shortens the construction period.

[0012] 5. This mold can be reused repeatedly. Attached Figure Description

[0018] The utility model will now be described in further detail with reference to the accompanying drawings and specific examples.

[0019] As shown in the attached diagram, this utility model discloses a modular forming mold for quick assembly and disassembly of precast pipe piles. It comprises multiple mold sections stacked vertically and connected by a connecting structure, where the bottom wall of the upper mold section is supported by the top wall of the lower mold section. Each mold section includes a ring-shaped steel forming mold 1 composed of two semi-circular steel forming molds. Bolted flanges 4 are provided at the joint of the two semi-circular steel forming molds. The two semi-circular steel forming molds are fixedly connected by bolts 3 passing through multiple bolt holes on the bolted flanges.

[0020] The connection structure includes a slot 5 located at the top of the bolted flange of each annular steel forming mold. In a multi-section mold stacked vertically, the lower part of the bolted flange of the upper annular steel forming mold can be inserted into the slot of the lower annular steel forming mold and fixedly connected by bolts passing through the slots and bolt holes on the bolted flange. The upper and lower annular steel forming molds can be stacked and connected by tightening bolts.

[0021] Multiple stiffening plates 2 are provided on the outer wall of the annular steel forming mold. Preferably, the stiffening plates are evenly spaced vertically on the outer wall of the annular steel forming mold.

[0022] Multiple pre-installed connecting pieces 7 are evenly connected to the outer wall of the circular steel forming mold along the same circumferential direction. Preferably, four pre-installed connecting pieces 7 are evenly connected along the same circumferential direction. In the multi-section, stacked mold, the multiple pre-installed connecting pieces on the topmost section are respectively connected to corresponding diagonal bracing members 9. An upper connecting piece 8 is rotatably connected to the upper end of each diagonal bracing member 9. Each upper connecting piece and its corresponding pre-installed connecting piece are fixedly connected by bolts. The lower end of each diagonal bracing member 9 is inserted into the soil to form a stable support system.

[0023] When splicing piles, the specific procedures are as follows:

[0024] 1. After cutting off the broken pile head, pour a cushion layer around the pile head, measure the pile splicing length, and configure modular molds.

[0025] 2. Lay out the lines and position the first mold section, then assemble and place it on the foundation layer, enclosing the pile head inside. Adjust the verticality of the first mold section and apply a release agent.

[0026] 3. Assemble and connect the modular molds in sequence to form a whole.

[0027] 4. Set up a special diagonal brace to fix the mold, and pour concrete into the mold.

[0028] The above-described specific embodiments are merely illustrative and not restrictive. Those skilled in the art can make many modifications under the guidance of this utility model without departing from the spirit and scope of the claims, and these modifications are all protected by this utility model.
