High-strength main beam, high-strength composite beam and manufacturing method of high-strength composite beam
The invention discloses a high-strength main beam, a high-strength composite beam and a manufacturing method of the high-strength composite beam, the high-strength main beam comprises a beam body and a shear key, the shear key is formed by directly cutting one end of a high-strength steel web of the beam body, and according to the high-strength main beam, an upper flange or a top plate does not need to be arranged at the top end of the beam body to be connected with the shear key. And the consumption of materials is reduced. According to the technical scheme, the strength of the shear keys is higher than that of welding stud shear keys, and due to the fact that the shear keys and the high-strength steel webs are integrally formed, the strength of the shear keys can be adjusted by adjusting material selection of the beam body; by changing the shape of the cut shear key, the rigidity of the shear key can be conveniently adjusted, and damage to concrete at the connecting part is avoided. The sectional area of the end, away from the beam body, of the shear key is larger than that of the end, close to the beam body, of the shear key, in the high-strength composite beam, concrete can be embedded into the shear key side and clamped by the end, away from the beam body, of the shear key, and the strength of the connecting portion meets the use requirement of the high-strength composite beam.
本发明公开了一种高强主梁、高强组合梁及高强组合梁的制造方法，高强主梁包括梁本体与剪力键，剪力键由梁本体的高强钢腹板的一端直接切割成型，该高强主梁不必在梁本体的顶端设置上翼缘或顶板以供连接剪力键，减少了材料的消耗量。本技术方案中的剪力键的强度较焊钉剪力键更强，且因与高强钢腹板一体成型，可以通过调整梁本体的选材来调整剪力键的强度；通过改变切割出的剪力键形状，可以方便地调整剪力键的刚度，避免引起连接部位的混凝土的损伤。剪力键的远离梁本体的一端的截面积大于靠近梁本体的一端的截面积，在高强组合梁中，混凝土能够嵌入剪力键侧且被剪力键的远离梁本体的一端卡住，使得连接部位的强度满足高强组合梁的使用需求。
