Description

Technical Field

[0001] The utility model relates to the technical field of pier column molds, and specifically relates to an adjustable pier column mold. Background Technique

[0002] In the construction of precast bridges, due to the characteristics of large height, heavy weight, and diverse cross-section changes of precast pier columns, various types of templates are required during the production process to meet the construction needs. This not only results in large template weight, poor versatility, and high costs, but also causes quality problems such as many joints, serious slurry leakage problems, and poor appearance of components when using small pieces of templates for splicing, thus posing potential safety hazards. In addition, the installation and disassembly of templates mainly rely on manual operation of hoisting equipment, which is time-consuming, inefficient, and has high labor costs. In traditional production processes, workers need to use equipment such as aerial work platforms for high-altitude pouring operations, which require multi-party coordination and cooperation, posing great safety hazards.

[0003] The Chinese utility model patent with the patent publication number CN220362744U, which was publicly disclosed on January 19, 2024, discloses a mold assembly for precast pier columns. Its height and diameter are both built according to the diameter and height of the to-be-built precast pier column, and it has the advantages of improving construction efficiency, less construction floor area, less concrete work, and one-time forming of precast pier columns. However, it cannot be adjusted according to different specifications of pier columns, and the usage scenario is single. Content of the Utility Model

[0004] In view of the above problems, the utility model provides an adjustable pier column mold, which can select adjusting plates with different widths according to different specifications of pier columns, so that the same type of side mold can be applicable to a variety of different specifications of pier columns, increasing the applicable range of the device.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] An adjustable pier column mold includes side molds and a construction platform. The construction platform is fixed on the top of the side molds. An adjusting plate is clamped between the two side molds. The surface of the adjusting plate is fixed to the second rotating shaft, and the surface of one side mold is fixed to the first rotating shaft. One end of the hydraulic strut is rotatably connected to the second rotating shaft, and the other end of the hydraulic strut is detachably matched with the first rotating shaft.

[0007] Further, transverse ribs and longitudinal ribs are fixed on the surface of the side mold.

[0008] Further, pulleys are provided at the bottom of the side mold and the adjusting plate, and guide rails matching the pulleys are fixed on the ground.

[0009] Further, a supporting plate is fixed on the top of the side mold, and the top of the supporting plate is fixed to the construction platform.

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0024] As Figures 1 - 4 shown, the adjustable pier formwork of this embodiment includes side forms 1 and a construction platform 10. The construction platform 10 is fixed to the top of the side forms 1. An adjusting plate 7 is clamped between the two side forms 1. The surface of the adjusting plate 7 is fixed to the second rotating shaft 6, and the surface of one side form 1 is fixed to the first rotating shaft 4. One end of the hydraulic strut 5 is rotatably connected to the second rotating shaft 6, and the other end of the hydraulic strut 5 is detachably matched with the first rotating shaft 4.

[0025] The present utility model adopts the flexible stretching combination technology of the side forms 1 and the precise control of the adjusting plate 7 to realize the production of precast piers of various cross-section types, significantly improving the applicable range of the formwork; integrating the construction platform 10 with the formwork improves the safety of the production process, reduces the use of construction machinery, and avoids the information chaos and potential safety hazards that may occur during the multi-party collaborative operation of production personnel, boom lift drivers, signal workers, slingers, etc.

[0026] The side forms 1 are bent, cut and stamped from Q235B steel and used as concrete forming templates; the hydraulic strut 5 is an automatic telescopic rod member with a hydraulic system inside; the adjusting plate 7 is used to change the size when the side forms 1 are adjusted in size and is processed from Q235B steel; the construction platform 10 is cut and processed from checkered plate, and production personnel can walk on this platform.

[0027] Further, transverse rib plates 2 and longitudinal rib plates 3 are fixed to the surface of the side forms 1.

[0028] The transverse rib plates 2 and the longitudinal rib plates 3 are cut from square steel and are used to ensure that the side forms do not deform during production.

[0029] Further, pulleys 8 are provided at the bottoms of the side forms 1 and the adjusting plate 7, and guide rails 9 matching the pulleys 8 are fixed to the ground.

[0030] With the configuration of the guide rails 9 and the pulleys 8 at the bottom of the present utility model and the control of the driving mechanism, the input of manpower and machinery is significantly reduced. At the same time, the installation and disassembly efficiency of the formwork is improved, and the labor and machinery costs are reduced. The pulleys 8 are located at the bottoms of the adjusting plate 7 and the side forms 1, enabling the adjusting plate 7 to slide freely when the size changes; the guide rails 9 are located below the pulleys 8 and are processed from Q235B steel, aiming to provide a sliding track for the pulleys 8.

[0031] Further, a support plate 12 is fixed to the top of the side forms 1, and the top of the support plate 12 is fixed to the construction platform 10.

[0032] The support plate 12 is used to carry the construction platform 10.

[0033] Further, a guardrail 11 is provided on the top of the construction platform 10.

[0034] The guardrail 11 is made of galvanized square steel and is placed around the construction platform 10 to play a role in safety enclosure.

[0035] Furthermore, a rabbet that matches each other is provided between the side form 1 and the adjusting plate 7.

[0036] A rabbet is provided between the side form 1 and the adjusting plate 7. The rabbet not only reduces the influence of mortar leakage at the joint on the appearance of the precast pier column, but also solves the problem that the parallel joints of the mold are prone to deformation and dislocation, and enhances the strength of the splicing area through the interaction force, further ensuring the production quality.

[0037] The usage method of the utility model is as follows:

[0038] 1. Place the guide rail 9 on a flat mold table or the ground;

[0039] 2. Since there are pulleys 8 at the bottom of the side form 1 and the adjusting plate 7, place them on the guide rail 9;

[0040] 3. Fasten the two side forms 1 with tie bolts;

[0041] 4. When the size is not adjusted, the adjusting plate 7 is located at the panel part of the side form 1;

[0042] 5. Assemble the combined guardrail 11 and the construction platform 10 on the ground;

[0043] 6. Fix the support plate 12 on the side form 1 to ensure tight connection;

[0044] 7. After the combined guardrail 11 and the construction platform 10 are assembled, use a lifting device to lift them to the top of the mold and place them on the support plate 12, and connect and fix them with bolts;

[0045] 8. Paste a rubber strip at the rabbet position and polish it flat;

[0046] 9. Pour concrete from the middle vacancy of the construction platform 10;

[0047] 10. After pouring, wait for the concrete to reach the required strength, lift off the construction platform 10, loosen the tie bolts of the side form 1, and slide the two side forms 1 apart to complete the demolding of the precast pier column;

[0048] 11. When the size needs to be changed, first pull the two side forms 1 to the designed position;

[0049] 12. Then push the hydraulic strut 5. The side form 1 remains stationary under the action of the first rotating shaft 4, and the adjusting plate 7 moves to the other side under the drive of the second rotating shaft 6;

[0050] 13. After the adjusting plate 7 is pushed by the hydraulic strut 5 and moves to the corresponding position, the rabbet joints of the adjusting plate 7 and the side form 1 can be aligned and spliced. This staggered rabbet joint structure can prevent the concrete slurry from overflowing, and at the same time, interact at the joint position to ensure that the weak joint position does not deform.

[0051] 14. Then, repeating the above steps 5 to 10 can complete the production of precast pier columns.

[0052] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
