Pre-installation method for retard-bonded prestressed reinforcement
The invention discloses a retard-bonded prestressed reinforcement pre-installation method which comprises the following steps: A, firstly carrying out platform support construction according to site conditions, and then carrying out frame beam main reinforcement construction firstly and frame beam stirrup construction firstly; b, steel bars with the diameter being 10 mm are welded to frame beam stirrups constructed firstly according to the laying curve elevation of the retard-bonded prestressed steel bars; c, mounting the retard-bonded prestressed reinforcement on the mounting round cage, and moving the retard-bonded prestressed reinforcement on the platform support by using the mounting round cage. According to the construction method, firstly-constructed frame beam main reinforcements, firstly-constructed frame beam stirrups, retard-bonded prestressed reinforcements, phi 10mm reinforcements, later-constructed frame beam main reinforcements, later-constructed frame beam stirrups, frame beam side molds, a mounting round cage and a platform support are arranged, so that damage to retard-bonded prestressed reinforcement sheath rib grooves can be effectively avoided; the bonding anchoring performance of the retard-bonded prestressed reinforcement is guaranteed, construction and inspection are convenient, the working efficiency is effectively improved, and then the construction cost is reduced.
本发明公开了一种缓粘结预应力钢筋先装方法，其方法包括以下步骤：A、根据现场情况先进行平台支撑的施工，然后在进行先施工的框架梁主筋和先施工的框架梁箍筋施工；B、将Φ10mm钢筋根据缓粘结预应力钢筋铺设曲线标高焊接在先施工的框架梁箍筋上；C、将缓粘结预应力钢筋装在安装圆笼上，利用安装圆笼在平台支撑上移动。本发明设置了先施工的框架梁主筋、先施工的框架梁箍筋、缓粘结预应力钢筋、Φ10mm钢筋、后施工的框架梁主筋、后施工的框架梁箍筋、框架梁侧模、安装圆笼和平台支撑，可以有效的避免缓粘结预应力钢筋护套肋槽的损坏，保证了缓粘结预应力钢筋粘结锚固性能，且施工便利，检查方便，有效提高了工作效率，进而降低了施工的成本。
