具体实施方式Detailed ways
如图1所示，本实用新型实施例所述的一种张弦梁张拉工装，该张弦梁张拉工装包括：支撑架2，设置于所述支撑架2上的两个千斤顶1，所述两个千斤顶1分别通过钢筋6连接有用于与张弦梁的张拉端钢板5固定连接的钢筋端部套丝4。As shown in Fig. 1, a string string tensioning tool described in the embodiment of the present invention includes: a support frame 2, two jacks 1 arranged on the support frame 2, and the two jacks 1 The jack 1 is respectively connected with steel bar end sleeves 4 for fixed connection with the tension end steel plate 5 of the string beam 6 through steel bars 6 .
具体的，所述钢筋6为直径32mm的钢筋6，其中的钢筋端部套丝4通过至少两个螺栓与张弦梁的张拉端钢板5固定连接，所述的钢筋6滑动装配于所述支撑架2。Specifically, the steel bar 6 is a steel bar 6 with a diameter of 32 mm, and the wire 4 at the end of the steel bar is fixedly connected with the tension end steel plate 5 of the string beam through at least two bolts, and the steel bar 6 is slidably assembled on the support frame 2.
在工作时，将支撑架2固定好，同时，松开千斤顶1，使得钢筋端部套丝4位于张拉端钢板5的外侧，并通过螺栓使得钢筋端部套丝4与张拉端钢板5固定。固定好后，千斤顶1开始工作，通过钢筋6拉动钢筋端部套丝4运动，实现张拉端钢板5的拉伸，当张拉端钢板5到达所需的位置时，固定与张拉端钢板5固定连接的钢拉索索头6，从而使得张拉端钢板5保持在拉伸的位置。When working, fix the support frame 2, and at the same time, loosen the jack 1 so that the steel bar end thread 4 is located outside the tension end steel plate 5, and the steel bar end thread 4 and the tension end steel plate 5 are connected by bolts. fixed. After being fixed, the jack 1 starts to work, and the wire 4 at the end of the steel bar is pulled by the steel bar 6 to move to realize the stretching of the tension end steel plate 5. When the tension end steel plate 5 reaches the desired position, the fixed and tension end steel plate 5 fixedly connected steel cable head 6, so that the steel plate 5 at the tension end remains in the stretched position.
通过上述描述可以看出，通过固定在支撑板上的两个千斤顶1可以很方便的将张弦梁进行拉伸，提高了张弦梁预紧力的拉伸施工。It can be seen from the above description that the string string beam can be easily stretched by the two jacks 1 fixed on the support plate, which improves the stretching construction of the string string beam pre-tightening force.
本实用新型不局限于上述最佳实施方式，任何人在本实用新型的启示下都可得出其他各种形式的产品，但不论在其形状或结构上作任何变化，凡是具有与本申请相同或相近似的技术方案，均落在本实用新型的保护范围之内。The utility model is not limited to the above-mentioned best implementation mode, anyone can draw other various forms of products under the enlightenment of the utility model, but no matter make any changes in its shape or structure, all have the same features as the application Or similar technical schemes all fall within the protection scope of the present utility model.
