Description

Construction method for improving installation precision of embedded plate Technical Field The invention relates to the technical field of building construction, in particular to a construction method for improving the installation precision of an embedded plate. Background In the building construction process, the main structure construction of a steel-concrete combined form is often involved, namely, embedded steel plates or other steel structure embedded parts are arranged in a concrete structure, the embedded parts or main ribs connected with the embedded parts deviate and templates on two sides of the embedded parts expand in the casting process, and the forming quality is affected. In the prior art, the control measures generally adopt the method that firstly, according to the measurement lofting size, the anchor bars of the embedded plates are directly fixedly connected with the steel bars of the main beams, the method meets the requirement of structural anchoring, but in the concrete pouring process, the steel bars of the main beams are displaced, so that the embedded plates are very easy to deviate and finally the embedded deviation occurs, secondly, the traditional embedded plates are synchronously arranged with the steel bars of the main beams, liang Tifeng modules are arranged, the deformation caused by the steel bars of the beam body in the follow-up construction process can not be rechecked and adjusted, the position of the embedded plates can not be finally adjusted, the deviation of the embedded plates is finally caused, and the problem of die expansion is more easily caused in the position of the traditional embedded plates, although the deviation of the embedded plates can be prevented in a clamping piece reinforcing mode, but the problem of die expansion is not effectively solved.
