Support-free pier column underpinning steel cover beam structure
The invention discloses a support-free pier column underpinning steel cover beam structure, and relates to the technical field of steel cover beams. The structure comprises two steel cover beam side boxes, steel cover beam end cross beams are connected between the two ends of the two steel cover beam side boxes, and an underpinning cross beam and a steel cover beam common cross beam are further connected between the two steel cover beam side boxes. The steel cover beam common cross beam is connected between the two steel cover beam side boxes, each cross beam for underpinning is composed of two symmetrical beam bodies, and the two beam bodies define a pier column hole so as to be arranged on a pier column needing to be dismantled in the current situation in a sleeving mode. When the structure is used, no temporary support needs to be erected, construction is convenient, and the influence on the space under the bridge is small; large-area steel bar planting does not need to be carried out on the current bent cap, construction is convenient, and damage to an original structure can be effectively reduced; the construction period can be effectively shortened without binding a newly-built bent cap or expanding section reinforcing steel bars on site and erecting a template; the method is not limited by the existing pier column structure type, and can be flexibly suitable for underpinning design of pier column types such as uncovered beam column type piers and covered beam column type piers.
本发明公开了一种免支架墩柱托换钢盖梁构造，涉及钢盖梁技术领域；该构造包括两个钢盖梁边箱，两个钢盖梁边箱的两端之间均连接有钢盖梁端横梁，两个钢盖梁边箱之间还连接有托换用横梁和钢盖梁普通横梁；钢盖梁普通横梁连接于两个钢盖梁边箱之间，每个托换用横梁由两部分对称的梁体构成，两部分梁体围合形成墩柱孔，以套设在现状需拆除墩柱上；使用该构造无需搭设临时支架，施工便捷，对桥下空间影响小；无需对现状盖梁进行大面积植筋，施工便捷，可有效减少对原结构的破坏；无需现场绑扎新建盖梁或扩大截面钢筋，无需搭设模板，可有效缩短施工周期；不受既有墩柱结构类型限制，可灵活适用于无盖梁柱式墩、盖梁柱式墩等墩柱类型的托换设计。
