The invention relates to the field of steel structure construction, in particular to a self-calibration grid frame suitable for an uneven terrain and a construction method thereof. The self-calibration grid frame is characterized in that the self-calibration grid frame comprises vertical columns (1), a rectangular cross beam (2), bearing buckles (3), a supporting plate (4) and a plumb (5); whereinthe vertical columns (1) are vertically arranged at four corners of the bottom of the rectangular cross beam (2), the bearing buckles (3) are arranged on the vertical columns (1) in a sleeving mode,and the bearing buckles (3) are used for supporting the rectangular cross beam (2); the supporting plate (4) is paved on the rectangular cross beam (2); and the plumb (5) is hung at the bottom centerof the supporting plate (4). According to the self-calibration grid frame, all parts are formed in a factory, and are assembled according to the site terrain conditions; and wherein a circular hole isformed in the supporting plate to fix the position of a grid frame sphere, the plumb is designed at the hole center and used for aligning with the projection position of the center ground of the gridsphere, and the supporting plate can be adjusted to tightly eject the nut position to make the plumb align with the ground projection position of the sphere.

本发明涉及钢结构施工领域，具体是一种适用于不平整地形的自校准网架及其施工方法；其特征是：包括，包括立柱（1）、矩形横梁（2）、承压卡扣（3）、支承板（4）、线坠（5）；其中，立柱（1）竖直设立在矩形横梁（2）的底部四角，在立柱（1）上套设承压卡扣（3），所述承压卡口（3）用于支托矩形横梁（2）；在矩形横梁（2）上铺设支承板（4）；在支承板（4）的底部中央悬挂线坠（5）。本网架的所有部件工厂制作成型，根据现场地形条件拼装成型即可；其中，支承板开设圆孔固定网架求位置，孔中心设计线坠，用以对准网架球体中心地面投影位置，可通过调整支承板顶紧螺母位置使线坠对准球体地面投影位置。
