摘要:
喷涂式冷弯薄壁型钢轻质砂浆墙体是一种在冷弯薄壁型钢墙体骨架区格间放置聚苯乙烯泡沫板(EPS板),并在型钢骨架与EPS板间以及骨架两侧喷涂轻质砂浆的新型“夹心式”墙体.通过对3根新型冷弯薄壁型钢墙体立柱试件的轴压性能试验,研究新型墙体立柱的受力过程、承载能力和破坏模式,将新型墙体立柱的试验结果与双面挂板立柱结果以及有效截面法计算结果进行对比;并对镀铝锌钢板与轻质砂浆之间的粘结滑移性能进行了初步的试验研究.研究结果表明:新型冷弯薄壁型钢墙体立柱的破坏现象为柱顶的局部压曲,新型墙体立柱与双面挂板立柱相比具有较高的承载力和较好的整体性,有效截面法计算立柱承载力较为保守;镀铝锌钢板与轻质砂浆间的平均粘结强度约为0.266 MPa,钢板的埋置深度与轻质砂浆厚度对两者之间的平均粘结强度影响较小.
Abstract:
The cold-formed thin-wall steel framing wall with sprayed lightweight mortar is a new type of characteristic of wall that a frame made of cold-formed thin-wall steels that is filled with expanded polystyrene sheets (EPSs) in the lattices and spray lightweight mortar onto the gaps between the frame and EPSs and surfaces of the wall. Three studs in the cold-formed thin-wall frames were tested and analyzed in this paper to study the bearing capacity and failure patterns under axial force of this new structure. Compared with the test results on the wall studs with double wallboards, it shows that the new type of studs have better bearing capacity and good wholeness. Compared with the calculated values that use the effective section method, it shows the effective section method is conservative. The failure mechanism of the cold-formed thin-wall steel framing wall studs is the buckling at the top of the studs. It is also tested on the bond slip property between the galvanized steel plates and lightweight mortar, showing that the average bond strength is 0.266 MPa. The parameters of depth of steel plate in the mortar and the thickness of mortar have little effect on the average bond strength
