Embodiment Construction
[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] like figure 1 , figure 2 As shown, the detachable slide block used for sliding construction provided by the present invention includes a slide block distribution beam 1 and a slide shoe 2 arranged under the slide block distribution beam 1, two slide shoes 2 are distributed along the slide block The length direction of the beam 1 is symmetrically arranged on the left and right, and the slider distribution beam 1 and the sliding shoe 2 are fixed by bolt connection. This connection method facilitates the removal and separation of the slider distribution beam 1 and the sliding shoe 2.
[0020] The slider distribution beam 1 includes a load-bearing beam 3 , a first slide plate 11 and a reaction force seat 12 . The load-bearing beam 3 is welded as a whole by the shaped steel 13 and the reinforcing rib 14. The shaped steel 13 includes a horizontal part 131 and a v...

The invention discloses a separable sliding block for sliding construction, which comprises a sliding block distribution beam and sliding shoes which are arranged below the sliding block distribution beam. The number of the sliding shoes is two and the two sliding shoes are symmetrically distributed on the left and the right along the sliding block distribution beam. The sliding block distribution beam is fixedly connected with the sliding shoes through bolts. The sliding block distribution beam comprises a load bearing beam, a first sliding plate which is fixedly arranged on the top surface of the load bearing beam and two counterforce seats which are welded on the top surface of the load bearing beam. Each sliding shoe comprises a load bearing block, a second sliding plate which is fixedly arranged on the bottom surface of the load bearing block and a limiting block which is welded on the bottom surface of the load bearing block. The separable sliding block for sliding construction provided by the invention has the advantages that only small mechanical equipment is required for removing the sliding shoes and replacing cushion blocks in the construction process, the operation is convenient and rapid to conduct and can be completed within short time, and the construction efficiency is greatly improved.
Description
technical field [0001] The invention relates to bridge construction equipment, in particular to a detachable sliding block for sliding construction. Background technique [0002] Sliding construction is an important bridge prefabricated assembly construction technology. It is widely used in the construction of bridges with structural forms such as concrete continuous beams, steel box girders, and steel truss girders. It slides along the longitudinal bridge to the design position for assembly, and the key equipment is the force-transmitting component between the beam section and the slideway—the slider. [0003] At present, integral sliders are mainly used in construction. The design of this type of sliders is generally higher in order to meet the operating space requirements during the construction process (such as jacking up). After the beam section slides to the design position, in order to reuse the more expensive materials such as the slide plate on the slider, the slid...
