Embodiment Construction
[0045] The present invention will be further described below in conjunction with accompanying drawing:
[0046] A construction method without support for the tie-beam of the thin-walled high pier with two limbs, comprising the following steps:
[0047] S1. The elevation of the top of the climbing formwork after climbing is located at the bottom elevation of the tie beam minus the height of the lower chamfer of the tie beam, and the pier body concrete of this section is poured;
[0048] S2. When the concrete reaches a certain strength, remove the suspension beam on the top of the climbing formwork (the suspension beam includes such as figure 1 The first suspension beam 2 shown and the second suspension beam 3) respectively install the formwork of the lower chamfering section of the tie beam, the formwork of the middle section of the tie beam, and the formwork of the upper chamfering section of the tie beam, and pour the lower chamfering section of the tie beam and the middle se...
