Net rack steel pull rod tensioning construction method and construction tool
The invention discloses a net rack steel pull rod tensioning construction method and construction tool. The net rack steel pull rod tensioning construction method comprises the steps that a tensioningtool is arranged on a net rack joint, and a tensioning device is installed on the tensioning tool; the two ends of a steel pull rod set are connected to the net rack joint; tensioning is conducted through the tensioning device till preset tensioning force is reached; and the tensioning device is dismounted. The net rack steel pull rod tensioning construction tool comprises a connecting body usedfor installing the tensioning device. When the tensioning device in the embodiment of the invention tensions a net rack, the steel pull rod set is also subjected to the tensioning force applied to thenet rack by the tensioning device and deforms, the tensioning force of the tensioning device is gradually transferred to the steel pull rod set, after tensioning of the net rack is completed and thetensioning device is dismounted, the degree of internal stress changes of the steel pull rod set after the tensioning device is dismounted is reduced, the tensioning tool on the net rack joint can also be applied to other construction processes after the tensioning device is dismounted, and universality and practicability are good.
本发明公开了一种网架钢拉杆张拉施工方法及施工工装，网架钢拉杆张拉施工方法包括在网架节点上设置张拉工装，将张拉设备安装于张拉工装上；将钢拉杆组的两端分别连接于网架节点上；通过张拉设备进行张拉直至达到预设张拉力；卸除张拉设备；网架钢拉杆张拉施工工装包括用于安装张拉设备的连接本体。本发明实施例中的张拉设备在对网架进行张拉时，钢拉杆组同样受到张拉设备向网架施加的张拉力并且产生变形，张拉设备的张拉力向钢拉杆组的逐渐转移，在网架张拉完成张拉设备卸载后，降低了张拉设备卸载后钢拉杆组内部应力变化的程度，并且网架节点上的张拉工装在张拉设备卸载后还可应用于其他施工工艺，通用性及实用性好。
