陽臺護欄施工方法的具體流程：

　　1、陽臺護欄基層清理

　　欄桿安裝前對陽臺護欄、梁、線條進行認真檢查，將板面基層上的灰塵、污垢等清理干凈，檢查陽臺安裝部位是否平整。

　　2、陽臺護欄預(yù)埋件安裝

　　欄桿預(yù)埋件的安裝只能采用后加埋件做法，其做法是采用膨脹螺栓（M8*100mm）與鋼板（100*100*5mm厚）來制作后置連接件。先在土建基層上放線，確定立柱固定點的位置，然后在安裝位置用沖擊鉆鉆孔，再安裝膨脹螺栓，螺栓保持足夠的長度，在螺栓定位以后，將螺栓擰緊同時將螺母與螺桿間焊死，防止螺母與鋼板松動。

　　3、成品陽臺護欄安裝

　　（1）欄桿安裝：安裝前檢查欄桿安裝位置，是否符合安裝要求。檢查好后開始安裝，安裝時，需雙人配合，一個扶住欄桿使其保持垂直與平整度。焊接從靠墻兩端點焊加固后，檢查欄桿安裝是否平整與垂直，然后點焊加固欄桿根部。待欄桿初安裝符合要求后，點焊加固安裝，在焊接時不能晃動，施焊要四周施焊，焊縫嚴密并應(yīng)符合焊接規(guī)范。

　?。?）陽臺護欄安裝必須由專業(yè)安裝單位施工。先拉通線、掛直，保證上下水平一致，并要求拉桿高度不小于1.1m，欄桿間距不大于0.11m；在核對護欄安裝預(yù)埋件的數(shù)量、規(guī)格、位置以及護欄與預(yù)埋件的連接節(jié)點符合設(shè)計要求。

　　4、打磨拋光：

　　出廠前陽臺護欄已按設(shè)計圖紙尺寸全部焊接好，并對焊縫用手提砂輪打磨將焊縫打平砂光，直到不顯焊縫為止。

　　5、粉末噴涂：

　　噴涂前必須將欄桿表面油污、鐵銹等垃圾清理干凈。噴涂應(yīng)平整、光滑不能有混色、垃圾及結(jié)塊，花藝表面紋路清晰。

The balcony guardrail construction methods of the specific process:

1, balcony guardrail cleaning at the grass-roots level

Railings before installation on the balcony guardrail, beam, line inspection earnestly, will base on the board face clean up dust, dirt, etc, check whether the balcony installation site is flat and level.

2, balcony guardrail embedded parts installation

Railings installation of embedded parts can only be used after add up, its practice is to use bolts (M8 * 100 mm) and plate (100 * 100 * 5 mm thick) to make the rear connectors. First pay-off in civil engineering at the grass-roots level, determine the position of the pillar fixed point, and then in the installation position with percussion drill hole, then install the expansion bolts, the length of the bolt to keep enough, after the bolt positioning, tighten bolts between the nut and screw welded to death at the same time, to prevent the nut with steel plate is loose.

3, balcony protect stockade of finished product installation

(1) the rail installation: installed check rail installation location before, meets the installation requirements. Check and start the installation, when installation, need to double match, a vertical and hold the rail to keep its flatness. After welding from the spot welding on both ends against the wall reinforcement, check whether the railings installation is flat and vertical, and then strengthen the railings root welding. After being early railings installation requirements, spot welding reinforcement installation, can not shake when welding, welding to around welding, weld closely and shall comply with the welding specification.

(2) the balcony guardrail installation must be installed by a professional unit construction. First pull wire, straight, ensure upper and lower levels, and demanded that the bar height not less than 1.1 m, parapet spacing is not more than 0.11 m; Check the fence installation of embedded parts in quantity, specifications, location, and guardrail and embedded parts connected nodes comply with the design requirements.

4, grinding polishing:

Before they leave the balcony guardrail have according to the size of design drawings all the good welding, and the welding welds with grinding wheel to draw with sanding, until do not show weld.

5, powder coating:
