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 omnidirectional adjusting device for the abutting connection of a prefabricated cap beam. The omnidirectional adjusting device comprises a base, wherein a center jack and slideable outer jacks are arranged on the base; the upper ends of the outer jacks are connected with slipping devices; the slipping devices comprise sliding plates and sliding bases; and the sliding plates are mounted in the sliding bases through rolling devices. The omnidirectional adjusting device for the abutting connection of the prefabricated cap beam can adjust the height of the cap beam by virtue of the basic function of the jacks; the omnidirectional adjusting device can correct the deviation angle between the cap beam and a predetermined position through bearing beam rotation of the outer jacks, and can also adjust the height difference between the center jack and the outer jacks so as to detach the outer jacks from the cap beam; and the omnidirectional adjusting device can change the relative position of the slipping systems and the cap beam by virtue of a rotating rod, thereby achieving the omnidirectional adjusting function. The omnidirectional adjusting device for the abutting connection of the prefabricated cap beam is simple in overall structure and convenient to mount, and is capable of effectively solving the position adjusting problem during the abutting connectionof the prefabricated cap beam and improving the abutting connection precision, 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...
