A kind of setting out method for bearing cushion stone construction

Abstract

The invention discloses a construction layout method for a bearing pad stone, which belongs to the technical field of bridge construction layout. In order to solve problems in the prior art that the bearing pad stone is hard to measure in construction layout and a bearing cannot be closely laminated with a pre-embedded steel slab at the bottom of a precast beam due to unavoidable influences from dimension errors of the precast beam and the pre-embedded steel slab at the bottom of the precast beam, the construction layout method for the bearing pad stone comprises the following steps of step 1, making a precast end steel reinforcement framework model; step 2, making a model steel slab and connecting the precast end steel reinforcement framework model with the model steel slab; step 3, mounting the precast end steel reinforcement framework model; and step 4, laying out the bearing pad stone. The construction layout method for the bearing pad stone, disclosed by the invention, is suitable for construction layouts of the bearing pad stones on various prefabricated simply supported beams and at simply supported ends of continuous beams.

Description

technical field [0001] The invention specifically relates to a construction stakeout method for a support cushion stone, and belongs to the technical field of bridge construction stakeout. Background technique [0002] The support pad stone is set at the connecting part of the abutment, the top of the pier and the support. Whether the position of the support pad stone is accurate or not will directly affect whether the support can fit tightly with the steel plate at the bottom of the prefabricated beam. If the support appears Suspension will directly affect the service life of the support and even cause quality accidents. Generally, the measurement and lofting of bridge support pad stones is to accurately release the position of each support pad stone with a total station according to the design drawing after the construction of the cover beam is completed and before the construction of the support pad stones, and accurately measure the support pads with a level Stone desig...

Problems solved by technology

[0003] Therefore, the present invention is aimed at the difficulties in setting out and measuring the support pad stone construction in the prior art, and cannot overcome the influence of the size deviation of the prefabricated beam and the pre-embedded steel plate at the bottom of the prefabricated beam, which causes the support to be unable to fit tightly with the pre-embedded steel plate at the bottom of the prefabricated beam. To solve the problem, a method for lofting construction of support pad stones is provided, and the method includes the following steps:
