濟(jì)南遮陽(yáng)棚嵌板怎么加固?

來(lái)源:http://ajuxfs.cn/ 日期:2022-02-24 發(fā)布人:
支架鋼框架梁、柱腹板部位損壞形成網(wǎng)絡(luò)、分叉裂紋區(qū)或局部斷裂、過(guò)燒或燒穿,甚出現(xiàn)大面積孔洞等缺陷時(shí),宜采用面板修補(bǔ)
When the web of support steel frame beam and column is damaged, forming network, bifurcation crack area or local fracture, overburning or burn through, and even large-area holes and other defects, panel repair should be adopted
1. 檢查確定缺陷的范圍;
1. Check and determine the scope of defects;
2. 若剔除缺陷,應(yīng)將其切割成圓角矩形孔,剔除零件的尺寸應(yīng)比缺陷范圍的尺寸大100mm;
2. If defects are removed, they shall be cut into rounded rectangular holes, and the size of the removed parts shall be 100mm larger than the size of the defect range;
3.將厚度和材料相同的面板插入切割部分,在嵌入面板的長(zhǎng)邊和寬邊與切割孔的兩側(cè)之間留出2 ~ 4mm的間隙,并將邊緣加工成接合所需的槽;濟(jì)南遮陽(yáng)棚
3. Insert the panel with the same thickness and material into the cutting part, leave a gap of 2 ~ 4mm between the long and wide sides of the embedded panel and both sides of the cutting hole, and process the edge into a groove required for joint;
4. 面板定位后,將孔板四角預(yù)熱100 ~ 150℃,采用分段分層反焊法焊接;
4. After the panel is positioned, preheat the four corners of the orifice plate to 100 ~ 150 ℃, and weld with sectional and layered reverse welding method;
5. 檢查焊縫質(zhì)量,打磨焊縫補(bǔ)強(qiáng),使其與原構(gòu)件表面齊平;
5. Check the weld quality and polish the weld reinforcement to make it flush with the surface of the original component;
當(dāng)使用附加蓋板修補(bǔ)裂縫或塊狀缺陷時(shí),一般采用雙蓋板。此時(shí),有必要在裂紋的兩端鉆一個(gè)裂紋止裂孔,所有的大量缺陷。蓋板焊接連接時(shí),應(yīng)將加固后的蓋板按原板厚度壓緊。焊腿的尺寸等于板的厚度。濟(jì)南遮陽(yáng)棚的尺寸和焊接順序可參考面板的要求。
When additional cover plates are used to repair cracks or blocky defects, double cover plates are generally used. At this time, it is necessary to drill a crack stop hole at both ends of the crack to remove all a large number of defects. When the cover plate is welded and connected, the reinforced cover plate shall be pressed according to the thickness of the original plate. The size of the welding leg is equal to the thickness of the plate. The size and welding sequence of Jinan sunshade can refer to the requirements of the panel.
