Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and in particular relates to a cantilever construction hanging basket track leveling device. Background Art

[0002] The hanging basket suspended casting process has the characteristics of ignoring terrain and having little impact on ground traffic. It is an effective method to cross existing roads, rivers or complex terrain, and plays an important role in the field of bridge engineering.

[0003] The hanging basket is a load-bearing frame that can slide or roll along the top of the beam. The hanging basket is anchored and suspended on the constructed beam section, providing an aerial platform for the construction of the next section. After completing the construction of one section, the hanging basket can be moved forward and fixed to carry out the construction of the next section, and this cycle will continue until the cantilever pouring is completed. In the existing hanging basket hanging pouring technology, the installation quality of the hanging basket is the key to affecting the pouring quality and construction safety, especially the flatness of the hanging basket track, which has a direct impact on the stability of the main truss and the uniform force on the main truss. Under the influence of factors such as the transverse slope and longitudinal slope of the bridge, the distance between the main truss of the hanging basket track and the ground usually changes within a certain range, so the track needs to be leveled. At present, the common track leveling methods are high-strength mortar leveling method and steel beam leveling method, but both have problems to varying degrees.

[0004] For the high-strength mortar leveling method, insufficient mortar strength, inadequate mortar curing, and small mortar thickness may cause the mortar to break during the use of the hanging basket. The degree of damage to the mortar cushion layer under different tracks is different, and the settlement or offset that occurs will reduce the stability of the hanging basket installation. For the steel pad beam leveling method, the pad beam is usually made of I-beam or double-piece channel steel, and its height is the existing market specification. It cannot be adjusted with the longitudinal and transverse slopes of the bridge. The height gradient can only be achieved by filling the gap between the pad beam and the bottom of the track with thin steel plates. Therefore, there will be problems such as track deformation due to inadequate gasket filling and deformation of the steel flange due to excessive pressure.

[0005] In order to solve the existing problems in the leveling process of the hanging basket track, a more accurate and stable hanging basket track leveling technology is needed. Utility Model Content

[0009] An elastic rubber block is arranged between the spherical concave basin and the spherical convex.

[0010] The support part includes a support steel plate arranged on the ground, and the spherical concave basin is arranged on the support steel plate.

[0011] Bolt fixing grooves are arranged at the four corners of the support steel plate.

[0012] The bolt fixing grooves include smooth grooves and threaded grooves, and the threaded grooves are located below the smooth grooves.

[0013] The adjustment part includes a leveling steel plate, and the spherical convex is arranged at the lower end of the leveling steel plate.

[0014] Threaded openings are arranged at the four corners of the leveling steel plate, and the adjustment device is a high-strength adjustment bolt.

[0015] The high-strength adjustment bolt is composed of an external high-strength leveling bolt and an internal high-strength fixing bolt.

[0030] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0031] A leveling device for a cantilever construction hanging basket track has the following composition structure:

[0032] As Figures 1 to 3 shown, a leveling device for a cantilever construction hanging basket track includes an adjusting part 3 arranged along the length direction of the hanging basket track 1. The track 1 is installed above the adjusting part 3. Adjusting devices 15 are arranged at the four corners of the adjusting part 3.

The screwing depth depends on the theoretical elevation of the leveling steel plate 6, as long as the deviation is not large. Then align the high-strength adjusting bolts 8 with the bolt fixing grooves 11 at the four corners of the supporting steel plate 4, so that the leveling steel plate 6 and the supporting steel plate 4 cannot move horizontally. Then use a wrench to rotate the high-strength leveling bolts 9 at the four corners, and screw the high-strength leveling bolts 9 into the smooth groove 13 to realize the leveling of the leveling steel plate 6.

It should be noted that after leveling, the spherical concave basin 5 and the spherical protrusion 7 should be in full contact through the elastic rubber blocks to make the force reasonable. After adjusting several such devices to the same elevation by the above method, place several tracks 1 on each leveling steel plate and connect them to realize the leveling of the hanging basket track.

[0038] Preferably, through the spherical protrusions 7, spherical concave basins 5 and the elastic rubber blocks therebetween, the weight of the hanging basket track 1 and the upper structure can be effectively supported. At the same time, the high-strength adjusting bolts 8 also participate in bearing the weight.
