Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings.
[0017] Such as Figure 1-6 As shown, the all-round adjustment device for the butt joint of the assembled cover beam includes a jack, an arc slider 2, a base 1, a connecting rod 6, a first sliding device 5, a second sliding device 8, a sliding plate 7, and a sliding plate base 10 , bolt 9 and rotating rod 11. The jacks include outer layer jacks 4 and center jacks 3 , wherein there are four outer layer jacks 4 arranged in a ring, and the center jack 3 is embedded in the base 1 . The base 1 is fixed with the bracket. The four outer layer jacks 4 form a whole through connecting rods 6 , and each of the bottom of the outer layer jacks is fixed with an arc slider 2 , which can slide in the annular chute of the base 1 . The rotating rod 11 is consolidated with a certain outer layer jack 4, and a quarter-circle slot is reserved on the base 1, and the rotating rod 11 drives ...

The invention discloses an all-round adjustment device for butt jointing of assembled cover beams, which comprises a base, on which a central jack and a slidable outer jack are arranged, and the upper end of the outer jack is connected with a sliding device, the The sliding device includes a slide plate and a slide plate base, and the slide plate is installed in the slide plate base through a rolling device. The present invention can utilize the basic function of the jack to adjust the height of the cover beam; the deflection angle between the cover beam and the predetermined position can be corrected through the rotation of the load beam of the outer layer jack, and the height difference between the center jack and the outer layer jack can also be adjusted, so that the outer layer jack and the outer layer jack can be adjusted. The cover beam is disengaged, and the relative position of the sliding system and the cover beam is changed through the rotating rod, so as to realize the function of all-round adjustment. The overall structure is simple and easy to install, which can effectively solve the problem of position adjustment when the assembled cover beam is docked, and improve the docking accuracy, construction efficiency and construction quality.
Description
technical field [0001] The invention relates to a bridge cover girder butt joint device, in particular to an omnidirectional adjustment device for an assembled cover girder joint. Background technique [0002] The construction of a large number of engineering projects such as high-speed railway network, expressway network, urban transportation network, and cross-river and sea bridges has provided a huge market and platform for bridge construction, and also requires bridge construction to shorten the construction period under the premise of ensuring construction quality , to increase the construction speed to respond to the urgent market demand for bridge construction capabilities. At present, prefabricated assembly technology has been widely used in the construction of the upper structure of bridges, which greatly improves the efficiency of on-site construction and the quality of components. However, the construction of the lower structure is still mainly based on manual bin...
