提高外墙模板边线的放线精度，在钢尺量距时采用统一标准钢尺，并采取固定拉

Improve the accuracy of laying out the side line of the external wall formwork. When measuring the distance of the steel rule, a unified standard steel rule is adopted, and a fixed tension is adopted to eliminate errors. The steel rule must be calibrated and adjusted in strict accordance with the requirements of the specification. <br>After the axis is basically placed, check it with a total station to ensure that the dimensions of the external wall axis are foolproof. <br>The woodworker shall support the mold strictly according to the design size, and check the verticality of every three layers to ensure the accuracy of the measurement.

Improve the line-out accuracy of the outer wall template edge, adopt a uniform standard steel ruler when measuring the distance of the steel ruler, and take a fixed pull to eliminate the error, the steel ruler must be strictly in accordance with the specification requirements of calibration and distance adjustment.<br>After the axis is basically placed, the whole station instrument is used for review to ensure that the size of the outer wall axis is foolproof.<br>Carpentry should be strictly in accordance with the design size of the support mold, each three layers of the verticality of the core, to ensure the accuracy of the measurement.

In order to improve the setting out accuracy of the side line of the external wall formwork, the unified standard steel ruler should be used when measuring the distance with the steel ruler, and the fixed tension should be adopted to eliminate the error. The steel ruler must be calibrated and adjusted in strict accordance with the specification requirements.<br>After the axis is basically placed, the total station is used to recheck to ensure that the axis size of the external wall is infallible.<br>Woodworking should be strictly in accordance with the design size of the formwork, every three layers of verticality to check, in order to ensure the accuracy of measurement.<br>
