Vertical inserts 豎直預(yù)埋件 Vapour barrier inserts will be fixed with fitments that were previously installed through formwork to ensure that the insert is held in position firmly during concreting operations. 隔汽預(yù)埋件通過一個穿透模板的固定件進(jìn)行固定以保證在混凝土作業(yè)過程中不會移位 。 The vertical insert shall be fixed temporarily by steel wire after hoisted to place by tower crane to keep the deviation of location and verticality Fujian LNG phrase 1 Additional 3 amp。 4 Tanks Project _____________________________________________________________________________________________________________________________ Method Statement for the Concrete Wall of LNG Tank ______________________________________________ REVISION :0 PAGE: 18/48 within the design requirement. The joint of inserts shall be welded by the mechanical subcontractor, and then inserts shall be checked and qualified before lifting and installing the inner formwork. Use steel clamps and tie rods to pull the insert closely contact the surface of formwork. Refer to Detail 1 of Appendix tie rod will pass through predrilled holes in the formwork and held the insert in position using a washer and wing nut. The wing nut will be hand tightened until the insert position is fixed by use of total station and then fully tightened. 垂直預(yù)埋件用塔吊吊至安裝位置后可用鐵絲進(jìn)行臨時固定，使埋件位置和垂直度偏差滿足設(shè)計要求。埋件連接處由機(jī)械分包商進(jìn)行焊接，然后由測量人員對埋件進(jìn)行檢查，符合規(guī)范要求后，即可將內(nèi)模板提升安裝，通過穿透模板的螺桿和鋼夾具將埋件拉動緊貼內(nèi)模表面。見附件 1 中詳圖 1。螺桿穿過模板上預(yù)先鉆透的孔并用墊片和蝶形螺母使埋件就位，蝶形螺母先用手?jǐn)Q緊，在全站儀檢查位置準(zhǔn)確后再最終緊固。 If it is found that there is a gap between the insert and formwork, the insert will be pushed into contact by way of a rebar which one end is covered with C50 concrete block. Refer to Detail 2 of Appendix 與模板之間留有空隙，須用一端套有 C50 混凝土塊的鋼筋將預(yù)埋件壓緊，使兩者接觸。 見附件 1 中詳圖 2。 . Horizontal inserts 水平預(yù)埋件 The first horizontal insert is located at a level of +515mm above the pile cap, its segmental ponents will be held in place by tying the stud welded on the rear face to the rebar by civil subcontractor. The segments shall be welded together by the mechanical subcontractor prior to concreting. 第一層水平預(yù)埋件埋于底板之上 +515mm 標(biāo)高處。土建分包商通過將焊于預(yù)埋件背 Fujian LNG phrase 1 Additional 3 amp。 4 Tanks Project _____________________________________________________________________________________________________________________________ Method Statement for the Concrete Wall of LNG Tank ______________________________________________ REVISION :0 PAGE: 19/48 面的錨固釘與附近鋼筋捆綁來固定預(yù)埋件。在混凝土施工前由機(jī)械分包商將各部件焊接成一個整體。 Should it be found necessary to push the horizontal strips to the formwork face, this will be done by concrete spacer between the insert strip and the rebar or by use of threaded rod and ，則須在預(yù)埋件板條和鋼筋間放置混凝 土 隔離塊，或者使用螺桿和鋼板。 The second horizontal insert is located at 4867mm above the pile cap. Its segmental ponents will be positioned by using steel clamps. Refer to Appendix 2 After welding together, it will be pulled to closely contact the surface of formwork by using clamps and tie rod through the formwork. Refer to Appendix 2. The last joint will be welded until the adjusting work is finished and the tolerance meets the requirements of specification. 第二件水平預(yù)埋件應(yīng)安裝在底板之上 4867mm，用鋼夾具將其逐個定位詳見 附件 2。在焊接后，用夾鉗和螺桿穿過模板將其拉到緊貼模板面詳見附件 2。調(diào)整完畢且誤差符合規(guī)定后方可焊接最后的接縫。 The third horizontal insert is located in the top of lift 10. Due to the weight of this ponent, the vertical inserts will support 平預(yù)埋件的位置在第 10 層頂部?？紤]到此部件的重量，豎直預(yù)埋件可以將其支撐住。 The sequence of installation of horizontal inserts shall be as follows: 水平預(yù)埋件安裝順序如下： a) The vertical insert shall be installed and fixed on the rebar firmly by steel clamps. 豎直預(yù)埋件應(yīng)安裝于鋼筋網(wǎng)上，用鋼夾具固定； b) The ponent of horizontal insert shall be hanged to sit on the top Fujian LNG phrase 1 Additional 3 amp。 4 Tanks Project _____________________________________________________________________________________________________________________________ Method Statement for the Concrete Wall of LNG Tank ______________________________________________ REVISION :0 PAGE: 20/48 of vertical inserts and connected by welding and fixed on the rebar by steel clamps. 單個水平預(yù)埋件吊裝放置在豎直預(yù)埋件之上并互相焊牢，用鋼夾具固定于鋼筋網(wǎng)上； c) After the location and radius checked and qualified, joints between adjacent ponents shall be welded as soon as possible except the last one. 安裝位置及半徑檢查并確認(rèn)合格后，盡快焊接各個相鄰部件的接縫，直至留下最后一個接縫； d) The inner formwork panels shall be installed from the opposite location of the last joint to two sides and the inserts shall be pulled to contact the face of formwork by steel clamps. 內(nèi)模板從最后一個接縫的對面開始向兩邊安裝。用鋼夾具將預(yù)埋件拉至緊貼模板面。 e) The last joint can be welded only after the location and radius of horizontal insert is checked and qualified. 水平預(yù)制件的位置與半徑都已經(jīng)過檢查并確認(rèn)合格后方可焊上最后的接縫。 .
