Partially prefabricated double-layer steel reinforced concrete L-shaped column
The invention discloses a partially prefabricated double-layer steel reinforced concrete L-shaped column. The partially prefabricated double-layer steel reinforced concrete L-shaped column comprises an L-shaped column shell and cast-in-place concrete, wherein the L-shaped column shell comprises prefabricated concrete and an L-shaped steel framework; the steel framework comprises outer-layer open-web type L-shaped steel and inner-layer solid-web type L-shaped steel; a checkered steel plate formwork is adopted between the prefabricated concrete and the cast-in-place concrete; the L-shaped steel framework comprises batten plates, angle steel and L-shaped steel; the L-shaped steel is formed by welding a web, side wing steel plates and cross-shaped steel; and studs are welded on two sides of the web to tie the concrete. The partially prefabricated double-layer steel reinforced concrete L-shaped column has the characteristics that the torsional strength of the L-shaped column is improved, cracks between the cast-in-place concrete and the prefabricated concrete are reduced, the durability, the toughness and the anti-seismic property of the structure are improved, and the bearing capacity and the ductility of the column are improved; and the problems that a full-prefabricated concrete column is difficult to hoist and transport, the time consumed by a cast-in-place concrete column is long, and the environment is polluted are solved.
本发明公开了一种部分预制装配的双层型钢混凝土L形柱，包括L形柱外壳和现浇混凝土，L形柱外壳包括预制混凝土和L形型钢骨架，型钢骨架包括外层空腹式L形型钢和内层实腹式L形型钢；预制混凝土与现浇混凝土之间采用花纹钢板支模，L形型钢骨架包括缀板、角钢和L形型钢，L形型钢由腹板、侧翼钢板和十字形型钢焊接而成，同时腹板两侧焊接有栓钉以拉结混凝土。本发明具有增强L形柱的抗扭强度、减少现浇混凝土与预制混凝土之间裂缝、提高结构的耐久性与韧性、抗震性能，以及柱子的承载能力和延性的特点，解决了全预制混凝土柱吊装运输困难，以及现浇混凝土柱耗时长以及污染环境的问题。
