Lofting method of continuous steel beam pier support
The invention relates to a lofting method of a continuous steel beam pier support, which and relates to the technical field of bridge construction. The method comprises the following steps: selectinga plurality of construction control points around a continuous steel beam; arranging a densification point on the pier top of each of two piers of the continuous steel beam, and enabling the construction control points and the densification points to jointly form a polygonal construction control network; acquiring coordinates of two encryption points based on a polygonal construction control network; and according to the coordinates of the two encryption points, obtaining the installation position of the support on each pier, and installing the support at the installation position. According to the construction method, the densification points are arranged on the pier tops of the two piers of the continuous steel beam, the densification points and the construction control points jointly form the polygonal construction control network, and the supports are set out on the basis of the densification points. The lofting method is simple and easy to operate, ensures that the absolute positions of the supports are coordinated and consistent with the designed positions, can also ensure the relative relation between the supports, and lays a good foundation for subsequent continuous steel beam assembly linear control.
本申请涉及一种连续钢梁桥墩支座的放样方法，涉及桥梁施工技术领域，其包括以下步骤：在连续钢梁的四周选取多个施工控制点；在连续钢梁的两个桥墩的墩顶上分别设置一个加密点，并使各施工控制点与加密点共同组成多边形施工控制网；基于多边形施工控制网，获取两个加密点的坐标；根据两个加密点的坐标，获取每个桥墩上的支座的安装位置，并在安装位置上安装支座。本申请通过采用在连续钢梁的两个桥墩的墩顶上布设加密点，加密点与施工控制点共同组成的多边形施工控制网，以加密点为基础，放样支座。放样方法简单易操作，既保证支座的绝对位置与设计位置协调一致，又能保证支座间的相对关系，为后续连续钢梁拼装线形控制打好基础。
