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.
