Description
Technical Field
[0001] The present application relates to the technical field of bridge construction, and more particularly, to a detachable formwork at the opening of a Y-shaped pier. Background Art
[0002] Y-shaped piers are commonly used pier forms in bridge engineering, which have the advantages of uniform stress, reduced number of piers, beautiful appearance, and adaptability to various terrains. During construction, usually, the steel reinforcement cage is woven into a Y shape first, and then the corresponding formwork is sleeved outside the steel reinforcement cage. Finally, concrete is poured into the formwork, and after the concrete solidifies, a Y-shaped pier is formed.
[0003] In the prior art, since there is an opening in the middle of the upper end of the Y-shaped pier (as shown in Figure 3 ), usually, an integral opening formwork is provided at this opening. The integral formwork has good integrity and low manufacturing cost, but it is inconvenient to hoist it to the opening during on-site construction. After the concrete solidifies, it is also inconvenient to remove the integral formwork from the opening, and it is easy to scratch the solidified concrete when removing it. In addition, the concrete in the formwork is usually poured from the topmost end of the pier column. However, when pouring concrete from the two struts at the top of the Y-shaped pier column, the concrete flows downward and accumulates. However, at the bifurcation of the pier column directly below the formwork at the opening, the concrete may not be fully filled, and it is also inconvenient to vibrate the concrete at this place, resulting in cavities below the bifurcation, thereby reducing the construction quality of the entire pier column.
[0004] Therefore, it is necessary for the inventor to design a new detachable formwork at the opening of the Y-shaped pier to overcome the above problems. Summary of the Invention
[0005] The main purpose of the present application is to provide a detachable formwork at the opening of a Y-shaped pier to solve the problems of inconvenient disassembly and assembly of the integral formwork at the opening and easy generation of cavities at the bifurcation of the Y-shaped pier column in the related art.
[0006] To achieve the above purpose, the present application provides a detachable formwork at the opening of a Y-shaped pier, including an arc-shaped bottom plate, two middle connecting plates, and two arc-shaped top plates. The arc-shaped bottom plate is fixedly arranged at the bottom of the opening of the Y-shaped pier. The two middle connecting plates are symmetrically and fixedly connected to the tops on both sides of the arc-shaped bottom plate. The two arc-shaped top plates are respectively fixedly connected to the tops of the two middle connecting plates;
[0007] An auxiliary pouring device and an auxiliary vibrating device are also fixedly arranged on the arc-shaped bottom plate.
[0008] Preferably, a number of first elliptical connecting holes are fixedly opened on both the arc-shaped bottom plate and the middle connecting plate. After the first bolt assembly is matched with the first elliptical connecting holes on the arc-shaped bottom plate and the middle connecting plate, the arc-shaped bottom plate and the middle connecting plate are fixedly connected.
[0009] Preferably, a number of second elliptical connection holes are fixedly formed on both the middle connecting plate and the arc-shaped top plate. After the second bolt assembly is engaged with the second elliptical connection holes on the middle connecting plate and the arc-shaped top plate, the middle connecting plate and the arc-shaped top plate are fixedly connected.
[0010] Preferably, transverse stiffening ribs and longitudinal stiffening ribs are fixedly arranged on the arc-shaped top plate, the middle connecting plate, and the arc-shaped top plate.
[0011] Preferably, the auxiliary pouring device includes a blanking hole fixedly arranged in the middle of the arc-shaped bottom plate.
[0012] Preferably, the auxiliary vibrating device includes a number of vibrating holes fixedly arranged on the arc-shaped bottom plate.
[0013] Preferably, two vibrating holes are provided, and the two vibrating holes are symmetrically arranged on both sides of the blanking hole.
[0014] Preferably, an auxiliary support member is further included, and the auxiliary support member is used for auxiliary support of the arc-shaped top plate.
[0015] Preferably, the auxiliary support member includes a telescopic rod, the top of the telescopic rod abuts against the upper end of the arc-shaped top plate, and the bottom of the telescopic rod abuts against the arc-shaped bottom plate.
[0016] A detachable template for the opening of a Y-shaped pier provided by the present utility model, compared with the prior art, has the following beneficial effects:
[0017] The integral template for the opening is divided into three parts: an arc-shaped bottom plate, a middle connecting plate, and an arc-shaped top plate. During assembly, they are installed sequentially from bottom to top until they form a shape corresponding to the opening. The split template for the opening is convenient for hoisting and disassembly, and is not likely to scratch the concrete surface during disassembly. In addition, an auxiliary pouring device and an auxiliary vibrating device are arranged on the arc-shaped bottom plate to perform separate concrete pouring and vibration on the bifurcated part of the pier column from the bottom of the opening template, avoiding the generation of cavities here and ensuring the quality of the Y-shaped bridge pier.

[0029] As Figure 1 、 Figure 2 shown, a detachable formwork at the opening of a Y-shaped pier includes an arc-shaped bottom plate 1, two middle connecting plates 2, and two arc-shaped top plates 3. The arc-shaped bottom plate 1 is fixedly arranged at the bottom of the opening of the Y-shaped pier. The two middle connecting plates 2 are symmetrically and fixedly connected to the tops on both sides of the arc-shaped bottom plate 1. The two arc-shaped top plates 3 are respectively fixedly connected to the tops of the two middle connecting plates 2. An auxiliary pouring device and an auxiliary vibrating device are also fixedly arranged on the arc-shaped bottom plate 1.
[0030] Specifically, the integral formwork at the opening is divided into three parts: an arc-shaped bottom plate 1, middle connecting plates 2, and arc-shaped top plates 3. During assembly, the arc-shaped bottom plate 1 is fixedly connected to the formwork at the non-bifurcated part of the lower part of the Y-shaped pier. After the arc-shaped bottom plate 1 is installed, the middle connecting plates 2 and the arc-shaped top plates 3 are installed successively from bottom to top until a shape corresponding to the opening is formed. The detachable formwork at the opening is convenient for hoisting and disassembly, and is not easy to scratch the concrete surface during disassembly. In addition, an auxiliary pouring device and an auxiliary vibrating device are arranged on the arc-shaped bottom plate 1 to separately pour and vibrate the concrete at the bifurcated part of the pier column from the bottom of the formwork at the opening, avoiding the generation of cavities here and ensuring the quality of the Y-shaped bridge pier.
[0031] A number of first elliptical connecting holes 4 are fixedly opened on both the arc-shaped bottom plate 1 and the middle connecting plate 2. After the first bolt assembly is matched with the first elliptical connecting holes 4 on the arc-shaped bottom plate 1 and the middle connecting plate 2, the arc-shaped bottom plate 1 and the middle connecting plate 2 are fixedly connected. A number of second elliptical connecting holes 5 are fixedly opened on both the middle connecting plate 2 and the arc-shaped top plate 3. After the second bolt assembly is matched with the second elliptical connecting holes 5 on the middle connecting plate 2 and the arc-shaped top plate 3, the middle connecting plate 2 and the arc-shaped top plate 3 are fixedly connected.
[0032] Specifically, the middle connecting plate 2 is connected to the arc-shaped top plate 3 and the arc-shaped bottom plate 1 through bolt assemblies respectively. However, since the formwork will be reused during construction, slight deformation may occur. In order to ensure that the bolt assemblies can still be installed after deformation, the connecting holes at each connection are set as ellipses, so that the formwork can still be butt-jointed and installed after slight deformation.
[0033] The transverse stiffeners 6 and longitudinal stiffeners 7 are fixedly arranged on the arc-shaped top plate 3, the middle connecting plate 2, and the arc-shaped top plate 3. Specifically, the structural strength of each component is improved by the transverse stiffeners 6 and longitudinal stiffeners 7, while reducing the weight of the formwork and ensuring that it has the required strength.
[0034] The auxiliary pouring device includes a blanking hole 8 fixedly arranged in the middle of the arc-shaped bottom plate 1. Specifically, a blanking hole 8 with a diameter of φ250mm is opened. The bifurcation part is poured with concrete separately through the blanking hole 8. After the concrete is completely attached to the arc-shaped bottom plate 1, the blanking hole 8 is blocked on-site and removed after the concrete solidifies.
[0035] The auxiliary vibrating device includes a plurality of vibrating holes 9 fixedly arranged on the arc-shaped bottom plate 1. Specifically, vibrating holes 9 with a diameter of φ90mm are opened. The concrete at the bifurcation of the pier is vibrated through the vibrating holes 9 to make the concrete evenly filled and voids are excluded. The vibrating holes 9 can be directly formed by cutting the arc-shaped bottom plate 1. The dropped steel plates during cutting are retained, and connecting hinge ears are welded between the steel plates and the arc-shaped bottom plate 1 and fixed by inserting φ20mm pins. When the concrete is poured to the position of the opening, this steel plate is used to block the hole.
[0036] Two vibrating holes 9 are arranged, and the two vibrating holes 9 are symmetrically arranged on both sides of the blanking hole 8. Specifically, vibrating on both sides at the same time makes the distribution of the concrete more uniform and ensures the quality of the pier.
[0037] It also includes an auxiliary support member, which is used to assist in supporting the arc-shaped top plate 3. The auxiliary support member includes a telescopic rod 10. The top of the telescopic rod 10 abuts against the upper end of the arc-shaped top plate 3, and the bottom of the telescopic rod 10 abuts against the arc-shaped bottom plate 1.
[0038] Specifically, during on-site construction, the arc-shaped top plate 3 is subjected to the downward pressure of the concrete, which easily causes the arc-shaped top plate 3 to bend towards the middle, resulting in loosening and deformation at the connection between the arc-shaped top plate 3 and the middle connecting plate 2, and further causing damage to the formwork and a decline in the quality of the pier. Therefore, the telescopic rod 10 is provided to assist in supporting the arc-shaped top plate 3, offset the bending deformation of the arc-shaped top plate 3, prevent it from being damaged and ensure the quality of the pier. The telescopic rod 10 here can be a telescopic rod in the form of a screw and a sleeve, and the two ends respectively abut against the longitudinal stiffeners 7 or transverse stiffeners 6 on the arc-shaped top plate 3 and the arc-shaped bottom plate 1 to prevent it from slipping and losing the supporting effect.
[0039] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and variations can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
