Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of highway precast beam construction, in particular to an adjusting device for the longitudinal and transverse slopes of beam shoes. Background Technique
[0002] Generally speaking, in the construction of mountain expressways, bridge projects are common. According to the design preferences of each design unit and the limitations of the terrain, the superstructure of bridge projects is generally precast beams. The advantages of precast beam bridges compared to cast-in-situ beam bridges are as follows: Precast beams are usually cast in the precast beam yard and then transported to the site for installation. The construction environment is more suitable compared to cast-in-situ beams. There is no need to worry about insufficient water supply and power supply, etc. It is more convenient to maintain. At the same time, when difficulties are encountered in beam construction, discussions and tests can be carried out, and corrections can be made in a timely manner. The impact on the environment is smaller. It can reduce the impact of noise and dust at the bridge installation site on the residents along the way, protect and improve the construction environment, ensure people's physical health, eliminate external interference, and ensure the smooth progress of construction.
[0003] There are technical standards for the longitudinal and transverse slopes of highways. To ensure that the installation position of the precast beam bearing and the overall periphery of the bearing are evenly and closely attached, it is necessary to set up a beam shoe structure at the beam bottom support position for longitudinal and transverse slope adjustment. In the past, the construction of beam shoes generally only adjusted the longitudinal slope, and the transverse slope was adjusted on the wing plates of the beam slab. This requires higher requirements for the formwork. There are many adjustment points at both wings of the beam length, increasing the construction difficulty and also having higher requirements for the construction team. Moreover, there are defects such as poor control of concrete overcasting, increasing the dead load burden and affecting the durability requirements. Content of the Utility Model
