SONG GONGWEN / JIANG YUANZHEN / DONG DESONG / YUAN ZHENG / LIAO HONGYU

The invention discloses a beam-column joint formwork reinforcing structure and a construction method. The beam-column joint formwork reinforcing structure comprises a beam-column pouring space formed by splicing and encircling a beam formwork, a column formwork and a floor formwork, and a reinforcing device used for fixing the shape of the pouring space. The reinforcing device comprises battens arranged on the outer sides of the beam formwork and the column formwork, formwork fasteners arranged on the outer sides of the battens, internal corner connecting pieces arranged at the joints of the three formworks and external corner connecting pieces arranged at the joints of the corners of the column formwork and the bottom face of the floor formwork. The formwork at the beam-column joint is reinforced in a targeted mode through the connecting pieces, so that the joints of the beam formwork, the column formwork and the floor formwork are connected into a whole to jointly resist outward tension of concrete, the bearing capacity of the formwork at the joint is greatly improved, the outward expansion amplitude of the formwork at the beam-column joint is reduced, and the construction efficiency is improved. And the phenomena of formwork expansion, inclination and meat biting of concrete caused by deformation, inclination and sinking of the formwork are effectively avoided.

本发明公开了一种梁柱节点模板加固结构及施工方法，包括由梁模板、柱模板和楼板模板拼接合围构成梁柱的浇筑空间、以及用于对所述浇筑空间的形状进行固定的加固装置；所述加固装置包括设置在梁模板和柱模板外侧的木方、设置在木方外侧的模板紧固件、设置在上述三种模板交接处的阴角连接件以及设置在所述柱模板拐角与所述楼板模板底面交接处的阳角连接件。本发明通过连接件针对性的对将梁柱节点处的模板进行加固，使梁模板、柱模板以及楼板模板的交接处连接成一个整体，共同抵抗混凝土向外的张力，大大提高了节点处模板的承受力，降低了梁柱节点处模板向外膨胀幅度，有效避免了因模板变形、倾斜和下沉而导致混凝土出现涨模、歪斜、咬肉的现象。
