Construction method for integral underpinning of lower foundation of masonry wall
The invention provides a construction method for overall underpinning of a lower foundation of a masonry wall, frame columns are arranged on the two sides of the span of an original masonry wall, a wall foundation is arranged below the original masonry wall, and the construction method comprises the steps that pre-fixing pieces arranged in the span direction are arranged on the two sides of the thickness direction of the original masonry wall, and pre-fixing pieces are arranged on the two sides of the thickness direction of the original masonry wall; the pre-fixing piece penetrates through a wall and is fixed; an upper support changing piece is installed between the frame column and the pre-fixing piece; and a lower support replacing piece is installed between the wall foundation and the pre-fixing piece. According to the construction method, before the underpinning beam under the wall of the original masonry wall is constructed, pre-fixing pieces are installed on the two sides of the original masonry wall in the thickness direction in advance and penetrate through the wall for fixation, and stability and safety of the masonry structure in the construction process are guaranteed; before large-area grooving, the pre-fixing piece is connected with the frame column through the upper support replacing piece, so that the masonry structure has certain self-bearing capacity, the situation that follow-up slotting influences the stability and safety of the structure, located above the pre-fixing piece, of an original masonry wall is avoided, and the construction efficiency is greatly improved.
本发明提供了一种砌体墙下基础整体托换的施工方法，原砌体墙的跨度两侧设置有框架柱，所述原砌体墙的下方设置有墙基础，所述施工方法包括：在所述原砌体墙厚度方向上的两侧布置有沿跨度方向设置的预固定件，所述预固定件穿墙固定；在所述框架柱和所述预固定件之间安装上换撑件；在所述墙基础和所述预固定件之间安装下换撑件。该施工方法，在原砌体墙的墙下托换梁施工前，预先在原砌体墙厚度方向上的两侧安装预固定件并穿墙固定，确保施工过程中砌体结构的稳定和安全；大面积开槽前，采用上换撑件将预固定件与框架柱相连，使砌体结构有一定的自承载能力，避免后续掏槽影响原砌体墙位于预固定件上方结构的稳定和安全性，极大增加了施工效率。
