Construction method of underpinning truss
The invention discloses a construction method of an underpinning truss, which comprises the following steps of: widening a reserved stand column for installing the underpinning truss in an existing building, pre-burying a connecting piece on the widened reserved stand column, and reserving a mounting gap between the upper end surface of the widened part of the reserved stand column and a top plate of a floor for installing the underpinning truss in the existing building; after the underpinning truss enters the existing building, the underpinning truss is lifted to a set height, then a temporary supporting structure is installed below the underpinning truss, the underpinning truss is supported on the temporary supporting structure, then the temporary supporting structure is manually pushed, and the end of the underpinning truss is moved into the installation gap; then the underpinning truss is hoisted again, and the temporary supporting structure is dismantled; and then the underpinning truss is lowered to the upper end face of the widened part of the reserved stand column, the position is adjusted, and finally the underpinning truss and the connecting piece are connected. The method has the effect of reducing the safety risk of dismantling part of the stand columns in the existing building.
本申请公开了一种托换桁架的施工方法，其先加宽既有建筑安装托换桁架的保留立柱，在加宽的保留立柱上预埋连接件，保留立柱的加宽部分的上端面与既有建筑安装托换桁架的楼层的顶板之间留有安装间隙；托换桁架进入既有建筑后，先将托换桁架吊起到设定的高度，然后在托换桁架的下方安装临时支承结构，托换桁架支撑在临时支承结构上，再人工推动临时支承结构，将托换桁架的端头移入到安装间隙内；然后再次将托换桁架吊起，拆除临时支承结构；之后下放托换桁架至保留立柱的加宽部分的上端面上并调整位置，最后连接托换桁架和连接件。本申请具有降低拆除既有建筑内的部分立柱的安全风险的效果。
