Segmented pouring prestressed beam structure and construction method thereof
The invention discloses a segmented pouring prestressed beam structure and a construction method thereof, and the segmented pouring prestressed beam structure and the construction method thereof are used for post-tensioned retard-bonded prestressed engineering prestressed beams. Reserved hole channels are formed in the pre-cast cross joints on the adjacent pre-cast plate sections so that tensioning sections of the pre-stressed tendons can penetrate through the pre-cast cross joints, after the post-cast plate sections are cast, the midspan sections of the pre-stressed tendons are embedded in the post-cast plate sections, and the tensioning sections of the pre-stressed tendons are arranged in the reserved hole channels in a penetrating mode; the post-pouring haunching structures are formed on the outer sides of the prestressed beams in a post-pouring mode so as to be used for fixing and tensioning the tensioning ends of the prestressed tendons, the combination and the method enable the prestressed building structure to be constructed by adopting a warehouse jumping method, then the construction efficiency of the long and thin building structure is improved, and the construction period of the building structure is shortened. The construction method solves the problem that when an existing long and thin building structure is constructed through a warehouse jumping method, part of prestressed structures cannot be constructed.
本发明公开了一种分段浇筑预应力梁结构及其施工方法，用于后张缓粘结预应力工程预应力梁，在建筑结构采用跳仓法施工时，先于先浇板段上的先浇交叉节中埋设锚固段，在相邻的先浇板段上的先浇交叉节中形成预留孔道以便后期预应力筋的张拉段穿设，在浇筑后浇板段后，将预应力筋的跨中段埋设于后浇板段中，并将预应力筋的张拉段穿设于预留孔道中，并在预应力梁的外侧后浇筑形成后浇加腋结构以用于预应力筋的张拉端的固定和张拉，该结合和方法使得预应力建筑结构采用跳仓法施工得以进行，进而提高了细长建筑结构的施工效率，缩短了建筑结构的施工工期。本发明解决了现有的细长建筑结构采用跳仓法施工时，部分预应力结构无法施工的问题。
