三,SL-80原位压力试验操作方法:

先在墙体上开凿两条水平槽孔 ①上水平槽尺寸应为 240mm×250mm×70mm(深×宽×高) ②下水平槽尺寸为 240mm×250mm×140m(深×宽×高),(下槽的高度视压力机型号不同而调整) ③上下水平槽孔对齐,两槽间相隔 7 皮砖,净距约 430mm④槽间砌体的承压面修平整

安放原位压力机 ①在上槽下表面和扁式千斤顶的顶面,均匀铺设厚 10mm 湿细砂垫层或石膏等其他材料,便于均匀 受力 ②将反力板置于上槽孔及扁式千斤顶置于下槽孔,并使两个承压板上下对齐后,拧紧螺母并调整其 平行度

试加荷载 检查测试系统是否灵敏以及上下压板和砌体受压面接触是否均匀密实,待正常后卸荷即开始测试。 4、正式测试 分级加荷,每级荷载约为预估破坏荷载的 10%,加至预估破坏荷载的 80%,连续加荷直至槽间砌体 破坏(当槽间砌体裂缝急剧扩展而压力表指针明显回退时,即为槽间砌体的破坏荷载)。

将破坏荷载换算成槽间砌体的抗压强度和标准砌体抗压强度,再与设计值对比,从而判明现有砌 体的真实强度。

数据分析。

Third, the operation method:
★ Firstly cut two horizontal slots on the wall. The horizontal slot size should be 240mm × 250mm × 70mm (depth × width × height). The horizontal slot size is 240mm × 250mm × 140m (depth × width × height). (The height of the lower groove is adjusted according to the different models of the press.) 3 The upper and lower horizontal slots are aligned. The two slots are separated by 7 bricks, and the clearance is 430mm. The bearing surface of the masonry is flattened.
★Place the in-situ press 1 on the lower surface of the upper trough and the top surface of the flat jack, evenly lay 10mm thick wet sand cushion or other materials such as gypsum to facilitate uniform force 2 to place the reaction plate in the upper slot and After the flat jack is placed in the lower slot and the two bearing plates are aligned, tighten the nut and adjust its parallelism.
★ Test load to check whether the test system is sensitive and whether the upper and lower pressure plates are in uniform contact with the pressure surface of the masonry, and the test is started after the normal unloading. 4, the official test graded loading, each stage of the load is about 10% of the estimated damage load, added to the estimated damage load of 80%, continuous loading until the inter-cavity masonry damage (when the inter-cavity masonry cracks expand sharply When the gauge pointer is obviously retracted, it is the breaking load of the masonry between the slots).
★ Convert the damage load into the compressive strength of the masonry between the slots and the compressive strength of the standard masonry, and compare it with the design value to determine the actual strength of the existing masonry.
★ Data analysis.
