The contribution of floor bearing plate in steel structure engineering is obvious to all, especially the advantages of wide application range and fast construction speed of floor bearing plate, which has established its position in the field of steel structure. Now let's talk about how to solve the quality problems in Jinan floor bearing plate construction.

1.幾何尺寸偏差和運(yùn)輸損傷

1. Geometric dimension deviation and transportation damage

這兩個(gè)問(wèn)題主要出現(xiàn)在加工過(guò)程中，因此，在樓承板開(kāi)始生產(chǎn)加工之前，安排人員對(duì)加工工藝、外觀和尺寸進(jìn)行檢測(cè)，符合要求之后再開(kāi)始批量生產(chǎn)。對(duì)于尺寸偏差超過(guò)要求的，或在運(yùn)輸途中受到損傷的構(gòu)件，輕微損傷現(xiàn)場(chǎng)維修，損傷嚴(yán)重的，應(yīng)進(jìn)行退回返修或換新。樓承板廠家認(rèn)為，這是一家負(fù)責(zé)任的企業(yè)應(yīng)該承擔(dān)的責(zé)任。

These two problems mainly occur in the processing process. Therefore, before the production and processing of the floor bearing plate, arrange personnel to inspect the processing technology, appearance and size, and start batch production after meeting the requirements. For components with dimension deviation exceeding the requirements or damaged during transportation, minor damage shall be repaired on site, and those with serious damage shall be returned for repair or replaced. The floor bearing plate manufacturer believes that this is the responsibility of a responsible enterprise.

2.邊角板變形

2. Corner plate deformation

在運(yùn)輸過(guò)程中沒(méi)有妥當(dāng)采取保護(hù)措施是造成邊角板變形的主要原因。樓承板廠家建議：在樓承板下方鋪設(shè)墊板，用打包帶或?qū)ｉT(mén)的角鋼包裝架捆扎，在周?chē)龊萌嵝苑雷o(hù)并且確保固定穩(wěn)妥，便可防止構(gòu)件之間的損傷。

The main reason for the deformation of the corner plate is that the protective measures are not properly taken during transportation. The manufacturer of the floor bearing plate suggests that: lay a base plate under the floor bearing plate, bind it with a packing belt or a special angle steel packing frame, provide flexible protection around it and ensure that it is firmly fixed, so as to prevent damage between components.

3.點(diǎn)焊脫開(kāi)

3. Spot welding separation

這里說(shuō)的“點(diǎn)焊脫開(kāi)”是桁架筋和鍍鋅板連接的焊接部分，這個(gè)問(wèn)題主要是由于桁架鋼筋直徑較粗，打彎不到位，導(dǎo)致虛假點(diǎn)焊。避免這個(gè)問(wèn)題，需要從源頭出發(fā)，會(huì)對(duì)桁架鋼筋彎曲設(shè)備進(jìn)行調(diào)試，以確保彎曲成型的準(zhǔn)確度。

The "spot welding separation" here refers to the welding part of the connection between the truss reinforcement and the galvanized plate. This problem is mainly due to the thick diameter of the truss reinforcement and the failure to bend it in place, which leads to false spot welding. To avoid this problem, we need to start from the source and debug the truss reinforcement bending equipment to ensure the accuracy of bending and forming.

另外，還應(yīng)加強(qiáng)焊接部分的質(zhì)量檢查。樓承板廠家通常的處理措施：如果是局部點(diǎn)焊脫開(kāi)可進(jìn)行現(xiàn)場(chǎng)復(fù)焊；如果情況較為普遍，就須返回處理。值得一提的是：如果點(diǎn)焊處的鍍鋅板有穿孔現(xiàn)象，應(yīng)對(duì)穿孔部位用膠封堵，另外，考慮到是焊接電流過(guò)大的問(wèn)題，因此應(yīng)對(duì)施焊電流進(jìn)行調(diào)試。

In addition, the quality inspection of welding parts shall be strengthened. Common treatment measures of floor bearing plate manufacturer: if it is local spot welding separation, conduct on-site re welding; If the situation is more common, it must be returned for processing. It is worth mentioning that if the galvanized sheet at the spot welding point has holes, the holes should be sealed with glue. In addition, considering the problem of excessive welding current, the welding current should be adjusted.

按照規(guī)定，材料在進(jìn)場(chǎng)前需要進(jìn)行再次復(fù)核，通常會(huì)出問(wèn)題的地方，以上就是問(wèn)題的相關(guān)解答了，您對(duì)此有什么內(nèi)容就來(lái)我們網(wǎng)站http://www.gp552.com咨詢(xún)吧！
