Use steel bars of the same grade and size and diameter to attach the steel frame, unscrew it, and tie it externally. Electric welding. It is important to ensure that after the connection is made, the steel bars on both sides of the relative component must be checked to ensure that they are at the same level.

極附加鋼筋電焊煌接規(guī)定單層焊，焊接長短10d，以避免鋼桁架側(cè)面失調(diào)。設(shè)計(jì)圖應(yīng)標(biāo)明預(yù)埋孔眼，并且孔眼四周應(yīng)設(shè)定筋板，當(dāng)樓層板遇到鋼梁必須當(dāng)場激光切割平面圖樣子產(chǎn)生變化時(shí)，激光切割位害也需要設(shè)定筋板，創(chuàng)口部位悍補(bǔ)橡膠支座鋼筋。

The electric welding of additional steel bars requires single-layer welding, with a welding length of 10d, to avoid lateral misalignment of the steel truss. The design drawing should indicate the pre embedded holes, and reinforcement plates should be set around the holes. When the floor slab encounters a steel beam and there is a change in the appearance of the laser cutting plan, the laser cutting position also needs to be set with reinforcement plates, and the rubber support reinforcement should be added to the wound area.

極筋板深層次鋼桁架橡膠支座內(nèi)，每側(cè)不少于被斷開承受力鋼筋總面積的一半且不少于212極豎直鋼筋桁架樓層板方位附加水面筋對于桁架上鏈墻，附加水面筋墻*混泥土鋼筋保護(hù)層必須確保較少做到15mm。

In the rubber bearing of deep steel truss of polar reinforcement plate, each side shall not be less than half of the total area of the disconnected load-bearing reinforcement and not less than 212 polar vertical reinforcement truss. For the upper chain wall of the truss, the additional surface reinforcement wall * concrete reinforcement protective layer must be less than 15mm.

極附加鋼筋的作業(yè)流程中，應(yīng)特別注意對早已鋪好的樓層板的防護(hù)工作中，不話合在熱鍍鋅板上走動或踐踏。亞禁隨便轉(zhuǎn)動，斷開鋼筋桁架:假如必須斷開，應(yīng)選用溝通交流型號規(guī)格的鋼筋將鋼行架再次連接

In the process of adding extra steel bars, special attention should be paid to the protection of already laid floor slabs, and it is not advisable to walk or trample on the hot-dip galvanized sheet. Prohibit arbitrary rotation and disconnection of the steel truss: If it is necessary to disconnect, the steel truss should be connected again using steel bars with communication and exchange models and specifications

鋼筋桁架樓層板附加鋼筋的綁扎施工順序

The binding construction sequence of additional steel bars for steel truss floor slabs

Additional steel reinforcement construction project and pipeline laying:

極必須按設(shè)計(jì)規(guī)定設(shè)定混凝土樓板連接鋼筋極橡膠支座鋼筋及其與鋼筋桁架樓層板豎直角度的鋼筋。并應(yīng)將其與鋼筋桁架綁扎，選用雙絲千變雙扣綁堅(jiān)固，連接鋼筋膠支座鋼筋按設(shè)計(jì)圖規(guī)定罟放，與鋼筋桁架直角度的鋼筋上筋應(yīng)依據(jù)設(shè)計(jì)圖放到鋼筋桁架上鏈鋼筋的下邊或上邊下筋應(yīng)放到鋼筋桁架晦桿鋼筋的上邊。

The connection steel bars of the concrete floor slab, the rubber support steel bars, and the steel bars at the vertical angle with the steel truss floor slab must be set according to the design regulations. And it should be bound with the steel bar truss, using double wire, variable, and double buckles to firmly bind it. The connecting steel bar rubber support steel bar should be placed according to the design drawing. The upper steel bar at a straight angle to the steel bar truss should be placed under or above the chain steel bar of the steel bar truss according to the design drawing. The lower steel bar should be placed above the hidden bar steel bar of the steel bar truss.

極鋼筋桁架鋪裝一部分總面積后，必須立即綁扎連接鋼筋橡膠支座鋼筋及其與鋼筋桁架豎直角度的鋼筋，保證樓層板連接成一個總體。

After laying a portion of the total area of the pole steel truss, it is necessary to immediately bind the steel bars connecting the rubber support steel bars and the steel bars at the vertical angle with the steel truss to ensure that the floor slabs are connected as a whole.
