Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a pier body construction mold connection device. Background Art

[0002] In the development of road and bridge construction, bridge engineering plays an important role. High piers of railway bridges often adopt hollow piers. It is usually more economical to use hydraulic climbing formwork for construction, especially for special-shaped piers and small numbers.

[0003] However, for some unusual piers, such as those with structural dimensions and cross-sectional forms that differ from other pier types and are relatively rare, hydraulic climbing formwork is often used. This formwork typically utilizes wooden formwork, which is highly practical for arc sections. However, some piers feature palletized caps, making climbing formwork impractical and requiring steel formwork. This leads to uneven connections and misalignment between the climbing and steel forms, increasing pier construction costs. Utility Model Content

[0004] The purpose of the utility model is to provide a pier body construction mold connection device that can solve the problem of uneven connection and misalignment between the climbing mold and the steel mold, thereby reducing construction costs.

[0005] The utility model is realized through the following technical solutions: a pier body construction mold connection device, including a steel template and a plurality of wedge-shaped connectors, the wedge-shaped connectors are arranged below the steel template, and the wedge-shaped connectors are provided with mounting holes; a climbing cone, which is pre-embedded in the pier body, and the climbing cone is connected and fixed to the wedge-shaped connectors through the mounting holes.

[0006] Furthermore, it also includes an air suction support, which includes a side strip and an air suction pipe. The side strip is provided with a negative pressure suction groove, and the air suction pipe is connected to the negative pressure suction groove.

[0007] Furthermore, sealing pads are provided on both sides of the side strips located at the negative pressure suction groove.

[0008] Furthermore, the negative pressure suction groove is an arc-shaped structure.

[0009] Furthermore, the wedge-shaped connecting member includes a vertical plate, a support plate and a rib plate. The vertical plate is vertically connected to the support plate. The support plate is connected to the steel formwork by threads. The rib plate is arranged in the middle of the vertical plate.

[0010] Furthermore, the rib plate, the support plate and the vertical plate are connected by welding.

[0011] Furthermore, a construction platform is installed on the outer edge surface of the steel formwork.

[0012] Furthermore, the steel template adopts a multi-piece splicing structure.

[0013] The technical solution of the present invention has at least the following advantages and beneficial effects: the present invention overlaps the supporting structure at the junction of the steel formwork and the climbing formwork, so that the construction connection between the steel formwork and the climbing formwork is smoother, effectively avoiding the problem of misalignment and reducing construction costs.

DETAILED DESCRIPTION

[0021] The following is further described in conjunction with specific embodiments. Figures 1-6 As shown, this embodiment is a pier body construction mold connection device, including a steel formwork 1 and a plurality of wedge-shaped connectors 2, the wedge-shaped connector 2 is arranged below the steel formwork 1, and the wedge-shaped connector 2 is provided with a mounting hole 211; a climbing cone 4, which is pre-embedded in the pier body 3, and the climbing cone 4 is connected and fixed to the wedge-shaped connector 2 through the mounting hole 211; specifically, if the pier body 3 is 40 meters high, the bottom pier height is within the range of 0-37m by hydraulic climbing formwork, and the top tray pier height is within the range of 37-40m by fixed steel formwork, and the two sets of molds need to be overlapped and transitioned. During construction, a row of M24 climbing cones 4 are pre-embedded along the pier body 3 in a circumferential direction, the wedge-shaped connector 2 is suspended below the steel formwork 1, and the climbing cone 4 is locked through the mounting hole 211.

[0022] It is worth mentioning that after the concrete pouring is completed and the formwork is removed, the misaligned joints should be polished in time.

[0023] like Figure 1 and Figure 5 As shown, this embodiment also includes an air suction support member 5, which includes a side strip 51 and an exhaust pipe 53. The side strip 51 is provided with a negative pressure suction groove 511, and the exhaust pipe 53 is connected to the negative pressure suction groove 511; specifically, in order to improve the supporting effect of the steel formwork 1, the side strip 51 has a certain elasticity and is arranged close to the surface of the pier body 3, and the negative pressure suction groove 511 is evacuated through the exhaust pipe 53 to form a vacuum, and the side strip 51 is adsorbed and tightly attached to the surface of the pier body 3.

[0024] More preferably, in order to improve the contact sealing, sealing rubber pads 52 are provided on both sides of the edge strip 51 located at the negative pressure suction groove 511 to effectively reduce the air leakage.

[0025] In this embodiment, the negative pressure suction groove 511 is an arc-shaped structure, so that when the suction pipe 53 is evacuating air, the negative pressure suction groove 511 will produce a certain elastic deformation.

[0026] like Figure 2 and Figure 6 As shown, the structure of the wedge-shaped connector 2 in this embodiment includes a vertical plate 21, a support plate 23 and a rib plate 22. The vertical plate 21 is vertically connected to the support plate 23. The support plate 23 is connected to the steel formwork 1 by threads. The rib plate 22 is arranged in the middle of the vertical plate 21. Through the combination of the three plates, it has good support and strength, and good anti-deformation ability.

[0027] It is worth noting that the rib plate 22, the support plate 23 and the vertical plate 21 are connected by welding.

[0028] In order to facilitate the workers' construction work, a construction platform 6 is installed on the outer edge surface of the steel template 1. The construction platform 6 is connected to the steel template 1 in a detachable threaded connection.

[0029] According to the shape of the pier body, the steel formwork 1 adopts a multi-piece splicing structure.

[0030] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
