Description

Technical Field

[0001] The utility model belongs to the technical field of bridge pier casting formwork, and particularly relates to a fixed formwork structure for bridge pier formwork. Background Art

[0002] A bridge pier is a supporting structure that supports at the bottom of the bridge body. Specifically, during the construction of a bridge, cast-in-place piles are first constructed in the river channel, and the steel cage structure at the upper end of the cast-in-place pile is formed into a pier through a casting method. The pier serves as a supporting structure to support the bridge body.

[0003] Specifically, during the casting process, a casting mold is pre-fitted outside the steel cage, and then concrete mortar is poured into the mold. After the concrete mortar solidifies, the steel cage is buried in the concrete structure layer.

[0004] During the casting process, since the formwork is segmented, it is hoisted down along the steel cage section by section by a crane, and after being assembled section by section, the installation of the formwork is completed. Depending on the height of the bridge, the number of formworks installed is often different.

[0005] In actual use, especially for the formwork used for piers with a relatively large radius, the formwork is often relatively large, characterized by a large formwork diameter and a large weight. During the suspension process by a crane, the steel wire rope on the crane is hung on the formwork. However, during the lowering process, the formwork is easily caught on the steel wire rope. Therefore, it is not only easy to shake, but the excessive shaking is likely to hit the steel cage structure. After being hit by the heavy formwork, the steel cage is prone to deformation.

[0006] At the same time, due to the shaking of the formwork in the hoisting state, it is difficult to align the formwork during docking. Specifically, when the upper formwork is suspended and placed on the top of the lower formwork, it is difficult to align the installation holes between the formworks. Therefore, during the lowering process, the operator needs to continuously correct the formwork. For a large-diameter and heavy formwork, it is also difficult to correct during the alignment process. Specifically, if all the assembly holes of a large-size and heavy formwork are to be aligned, it requires the cooperation of multiple operators. Therefore, it is very laborious to assemble the formwork during the docking process. Content of the Utility Model

[0007] Based on the above background, the purpose of the utility model is to provide a fixed formwork structure for bridge pier formwork.

[0008] To achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A fixed formwork structure for bridge pier formwork includes several formwork mechanisms for casting bridge piers, and the formwork mechanisms are detachably connected by means of assembly.

[0010] The template mechanism is assembled and guided through a guide rail mechanism. The guide rail mechanism includes a number of vertically arranged lower slide rail plates. The guide rail mechanism further includes a cylindrical base. The lower ends of the side walls of the lower slide rail plates are fixedly connected with a number of adjusting screws that are slidably connected to the cylindrical base.

[0011] The inner end of the adjusting screw is threadedly connected with a blocking nut that blocks the inner side position of the cylindrical base.

[0012] A number of lower slide rollers that abut and roll on the inner side wall of the lower slide rail plate are assembled and connected to the template mechanism.

[0013] During the process of assembling the template mechanism, the template mechanism abuts and rolls on the lower slide rail plate through the lower slide rollers, and is assembled after being accurately docked by the guidance of the lower slide rail plate.

[0014] Preferably, a ring base is fixedly connected to the bottom of the cylindrical base.

[0015] Preferably, a spring is fixedly connected to the lower end of the lower slide rail plate, and the spring is fixedly connected to the inner side wall of the cylindrical base.

[0016] Preferably, the template mechanism includes an inner mold cylinder, and rolling guide assemblies are respectively fixedly connected to the top cylinder opening and the bottom cylinder opening of the inner mold cylinder.

[0017] Preferably, the rolling guide assembly includes a ring seat. A number of guide openings are formed in the outer side wall of the ring seat, and lower slide rollers are rotatably connected in the guide openings.

[0018] During the guiding process, the lower slide rail plate is located in the guide opening and abuts and rolls on the lower slide rollers.

[0019] Preferably, annular mounting flanges are integrally formed at the top cylinder opening and the bottom cylinder opening of the inner mold cylinder respectively, and the ring seat is fixedly connected to the annular mounting flanges.

[0020] Preferably, a number of mounting holes are formed in the annular mounting flanges.

[0021] Preferably, the template mechanism further includes a strengthening structure fixedly connected to the outer side wall of the inner mold cylinder.

[0022] Preferably, the strengthening structure includes a number of vertical rib plates welded to the outer side wall of the inner mold cylinder. The vertical rib plates are distributed annularly, and arc-shaped connecting rib plates are welded between adjacent vertical rib plates.

[0023] The utility model has the following beneficial effects:

[0024] 1. When lowering the formwork mechanism during hoisting, the downward sliding rollers installed on the formwork mechanism are brought into contact with the downward sliding track plate. Under the contact of the downward sliding track plate, on the one hand, it avoids the shaking of the heavy formwork mechanism, which may easily cause the formwork mechanism to hit the steel reinforcement cage and lead to the deformation of the steel reinforcement cage. On the other hand, under the guidance, during the process of aligning the formwork mechanism, the installation holes on the formwork mechanism can be more easily aligned, facilitating the connection of the formwork mechanism.

[0025] During the process of lowering the formwork mechanism, since the formwork mechanism rolls on the downward sliding track plate by contact, the stability of lowering is very high.

[0026] 2. The rolling guide assembly includes an annular seat. A number of guide openings are provided on the outer side wall of the annular seat. A downward sliding roller is rotatably connected in the guide opening. During the guiding process, the downward sliding track plate is located in the guide opening and rolls on the downward sliding roller by contact. In this way, during the lowering process, the formwork mechanism can be lowered smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Embodiment 1

[0038] As Figures 1-5 shown, a fixed-form template structure for a bridge pier formwork includes a plurality of template mechanisms 2 for pouring bridge piers, and the template mechanisms 2 are detachably connected by a splicing method. The heavy and large-diameter template mechanisms 2 are butt-jointed and installed by a splicing method to form the entire template.

[0039] During the butt-joint installation of the template, in order to accurately align the installation holes on the template, improve the installation efficiency, and reduce the installation difficulty, the above-mentioned template mechanism 2 is guided and spliced by a guide rail mechanism 1.

[0040] Specifically, the guide rail mechanism 1 includes a plurality of vertically arranged downward sliding track plates 12, and the downward sliding track plates 12 are distributed in an annular array and are located outside the steel reinforcement cage. At the same time, the guide rail mechanism 1 further includes a cylindrical base 11 (a ring base 111 is fixedly connected to the bottom of the cylindrical base 11 for convenient and stable support). During the working process, the cylindrical base 11 is pre-lifted to the ground by a crane. At this time, the steel reinforcement cage passes through the cylindrical base 11.

[0041] The lower ends of the side walls of the above-mentioned downward sliding track plate 12 are fixedly connected with a plurality of adjusting screws 13 slidably connected to the cylindrical base 11; the inner ends of the adjusting screws 13 are threadedly connected with a blocking nut 131 that blocks the inner side of the cylindrical base 11.

[0042] In this way, after the cylindrical base 11 is hoisted and placed, the downward sliding track plate 12 - adjusting screw 13 is installed on the through holes correspondingly opened on the cylindrical base 11, and the distance between the downward sliding track plate 12 and the steel reinforcement cage is adjusted. The method is to adjust the position through the blocking nut 131. Specifically, after the distance of the downward sliding track plate 12 is adjusted, the blocking nut 131 is abutted against the inner side wall of the cylindrical base 11.

[0043] Correspondingly, a plurality of downward sliding rollers 26 that abut and roll on the inner side wall of the downward sliding track plate 12 are assembled and connected to the template mechanism 2.

[0044] During the hoisting and lowering of the template mechanism 2, the downward sliding rollers 26 installed on the template mechanism 2 are abutted against the downward sliding track plate 12. Under the abutment of the downward sliding track plate 12, on the one hand, it avoids the defect that the heavy template mechanism 2 shakes and easily hits the steel reinforcement cage, resulting in the deformation of the steel reinforcement cage. On the other hand, under the guidance, during the process of docking the template mechanism 2, the installation holes on the template mechanism 2 can be aligned more easily, facilitating the connection of the template mechanism 2.

[0045] During the process of lowering the template mechanism 2, since the template mechanism 2 abuts and rolls on the downward sliding track plate 12, the stability of the lowering is very high.

[0046] A spring 14 is fixedly connected to the lower end of the above-mentioned downward sliding track plate 12, and the spring 14 is fixedly connected to the inner side wall of the cylindrical base 11. The spring 14 facilitates improving the stability of the downward sliding track plate 12. Specifically, during the process of the downward sliding track plate 12 guiding the template mechanism 2, the downward sliding track plate 12 is in a tensioned state, and thus the downward sliding track plate 12 is fully abutted against the inner side wall of the cylindrical base 11. And after the guiding operation of the downward sliding track plate 12 is completed, loosening the blocking nut 131 facilitates the downward sliding track plate 12 to be detached from the template mechanism 2. The design of the spring 14 improves the stability of the guiding operation and the convenience of disassembly.

[0047] During the actual working process, in order to facilitate the disassembly of the downward sliding track plate 12, according to the existing detachable installation method of the spring 14, fixing pins (not shown in the figure) are fixedly connected to both ends of the spring 14. After the pins penetrate through the downward sliding track plate 12 and the cylindrical base 11, nuts are threadedly connected to the ends of the pins to play a blocking role. During the disassembly process, removing the nuts facilitates the separation of the downward sliding track plate 12 and the cylindrical base 11.

[0048] The length of the above-mentioned downward sliding track plate 12 is adjusted corresponding to the height of the steel reinforcement cage to ensure sufficient guidance.

[0049] Example 2

[0050] As Figures 1-5 shown, on the basis of the structure of Embodiment 1, the template mechanism 2 in this embodiment includes an inner mold cylinder 21, and rolling guide components are fixedly connected to the top cylinder opening and the bottom cylinder opening of the inner mold cylinder 21 respectively.

[0051] The rolling guide component includes an annular seat 25. A plurality of guide openings are formed in the outer side wall of the annular seat 25, and a downward sliding roller 26 is rotatably connected in the guide opening (both ends of the downward sliding roller 26 are fixedly connected with short rotating shafts and are rotatably connected to the guide opening).

[0052] During the guiding process, the downward sliding track plate 12 is located in the guide opening and rolls on the downward sliding roller 26 in a contacting manner. In this way, during the lowering process, it is ensured that the template mechanism 2 can be lowered smoothly.

[0053] Annular mounting flanges 22 are integrally formed on the top cylinder opening and the bottom cylinder opening of the inner mold cylinder 21 respectively, and the annular seat 25 is fixedly connected to the annular mounting flange 22.

[0054] A plurality of mounting holes 221 are formed in the annular mounting flange 22. During the docking process of the template mechanism 2, the mounting holes 221 can be accurately aligned through the above guiding method. Then, after the screw rod passes through the mounting holes 221, it is convenient to install nuts.

[0055] In order to improve the stability of the inner mold cylinder 21, the template mechanism 2 further includes a strengthening structure fixedly connected to the outer side wall of the inner mold cylinder 21. The strengthening structure includes a plurality of vertical rib plates 24 welded to the outer side wall of the inner mold cylinder 21. The vertical rib plates 24 are distributed annularly, and arc-shaped connecting rib plates 23 are welded between adjacent vertical rib plates 24.

[0056] Of course, the above description is not a limitation to the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the present invention should also fall within the protection scope of the present invention.
