電力蓋板生產(chǎn)工藝采用混凝土震動預(yù)制工具，將水泥混凝土倒入蓋板塑料模具后，通過震動平臺震動成型，自然養(yǎng)護(hù)至水泥凝固后即可脫模，完成整個生產(chǎn)工藝。
電力蓋板模具概況：全國各地鐵路、城市道路、鄉(xiāng)鎮(zhèn)水泥路、別墅區(qū)間路，開發(fā)區(qū)、廠區(qū)道路、水利工程等施工建設(shè)遍地開花，與之配套的窨井、雨水井、路牙、側(cè)石、平石、路肩石、護(hù)坡等預(yù)制構(gòu)件得到了前所未有的發(fā)展機(jī)遇!
傳統(tǒng)液壓鋼模生產(chǎn)設(shè)備投入成本高、維修復(fù)雜、技術(shù)要求高、產(chǎn)品表面密實性差、易松散。彩用塑模生產(chǎn)，投入成本低，初期即使投入幾千元也可投產(chǎn)，且舊模具有很高的回收價值，預(yù)制場地可隨工程搬遷，極為方便，產(chǎn)品密實性高、可表面彩色處理、安裝方便等多種優(yōu)點，得到眾多預(yù)制行業(yè)的認(rèn)可。材料準(zhǔn)備：砂、石應(yīng)有復(fù)試報告，水泥應(yīng)有出廠合格證及復(fù)試報告;鋼筋應(yīng)進(jìn)行外觀及資料(質(zhì)量證明書)檢查，并經(jīng)送樣復(fù)試合格;角鋼應(yīng)有合格證，進(jìn)場應(yīng)進(jìn)行外觀檢查，無變形翹曲現(xiàn)象，規(guī)格、型號、壁厚應(yīng)達(dá)到設(shè)計要求。
電力蓋板根據(jù)邊框放樣尺寸，又專人進(jìn)行角鐵畫線切割，角鐵兩頭切割45度拼角焊接，角鐵邊框焊接時不可有過燒、咬邊、夾渣等現(xiàn)象。焊接時為保證角鐵邊框尺寸一致、不變形，邊框底部可設(shè)置平整鋼板一塊，在鋼板上彈線，，四周用角焊出角鐵邊框模型，焊接時角鋼放入模型內(nèi)焊接加工為保證邊框內(nèi)混凝土與鍍鋅邊框粘結(jié)牢固，可在邊框內(nèi)側(cè)焊接若干螺紋鋼筋。
角鐵邊框水平放在預(yù)制場地上，在邊框底部鋪3mm橡膠皮，以保證成型后的蓋板底部不漏漿，且底部平整、光滑，底部混凝土不高出角鐵邊框。
電力蓋板安裝
運(yùn)輸時應(yīng)考慮蓋板受力方向，蓋板反向受力，容易造成蓋板斷裂，將蓋板擱置在電纜溝上，電纜溝兩頭采用經(jīng)緯儀每20m左右定點。拉線調(diào)整蓋板順直及平整度。蓋板擱置點底部擱置3mm厚橡膠皮墊，用以調(diào)整蓋板的穩(wěn)定性及表面平整度。
Electric shock cover production process using precast concrete tools , after the concrete is poured into molds plastic cover , through the vibration platform vibration molding , nature conservation after stripping to cement solidification can complete the entire production process.
Power cover mold Overview: country railways, roads, towns cement road , villas interval Road , Development Zone, site roads, water conservancy and other building construction everywhere, accompanying scenting wells, water wells , roads teeth, side stone, flat stone , curbs , slope protection and other precast been an unprecedented development opportunity !
Traditional hydraulic steel high production equipment investment costs , maintenance complex and technically demanding, dense surface of the product is poor , easy to loose . Color with mold production, low input costs , even though the initial investment can be put into a few thousand dollars , and the old mold has a high recovery value, the venue can be prefabricated with the relocation project , extremely convenient, high product density , surface- color processing , easy installation, and other advantages , precast industry recognition by many . Material preparation: sand, stone should re-examination report , the cement factory certification and re-examination should be reported ; reinforcement should be visually and information ( quality certificate ) examination and re-examination by sending samples qualified ; angles due certificate, should approach visual inspection , no distortion warping phenomenon , specifications, models , wall thickness should meet the design requirements .
According to the size of the border loft , and someone to draw a line cutting angle iron , angle of 45 degrees to fight two cutting angle welding , can not have had burned , undercut , slag and other phenomena angle iron welded frame . In order to ensure consistent welding angle iron frame size , no distortion, you can set the bottom border of a flat steel plate , steel shells on line , surrounded by a fillet weld the angle iron frame model , welding angle into the model of the welding process in order to ensure border concrete and galvanized steel frame firmly bonded, twisted steel can be welded on the inside of several border.
Horizontal angle iron frame on precast venue , shop 3mm rubber skin on the bottom of the frame to ensure that the bottom of the cover does not leak after forming the slurry , and the bottom flat, smooth , no higher than the bottom of the concrete angle iron frame .
Cover installation
Transport should consider the direction of the force plate , cover reverse force , likely to cause breakage cover , the cover rests on the cable channel, cable channel ends using theodolite every 20m or so designated . Pull the cover straight adjustment and flatness. Cover the bottom shelve shelve 3mm thick rubber Pidian point to adjust the cover stability and surface smoothness .
