Improved T-shaped steel prefabricated hollow plate girder bridge hinge joint structure and construction process thereof
The invention discloses an improved T-shaped steel prefabricated hollow plate girder bridge hinge joint structure. The structure comprises a transverse steel plate, T-shaped steel and a plurality of rivets. The whole body of the T-shaped steel is full of reinforcing steel bars. The T-shaped steel is arranged in an inverted T shape and is arranged at a hinge joint between the two hollow slab beams;the cross beam of the T-shaped steel is in contact with the bottoms of the two hollow plate beams, and the longitudinal beam of the T-shaped steel penetrates through a hinge joint between the two hollow plate beams; the reinforcing steel bars are inserted into a hinge joint between the two hollow slab beams in a penetrating manner; the transverse steel plates are connected with the T-shaped steellongitudinal beams and fixed to the hollow plate beams on the two sides through a plurality of rivets. The construction technology comprises the steps that firstly, T-shaped steel is directly inserted into the hinge joint from the position below the hinge joint; then the reinforcing steel bars are opened; the T-shaped steel and the transverse steel plates are installed at equal intervals in the length direction of the hinge joint, the T-shaped steel and the transverse steel plates are uniformly distributed at the hinge joint of the plate girder bridge, and concrete is poured; the transverse steel plates are connected with the T-shaped steel longitudinal beams and fixed to the hollow plate beams on the two sides through rivets. The overall strength of the hinge joint of the prefabricated hollow slab bridge is improved, and the transverse force transmission performance between slab beams is enhanced from the source.
本发明公开了一种改良T字钢预制空心板梁桥铰缝结构，包括横向钢板、周身布满钢筋的T字钢、多根铆钉；所述T字钢呈倒T形布置，设置在两个空心板梁间铰缝处；T字钢横梁与两个空心板梁底部接触，纵梁穿过两个空心板梁之间铰缝；所述钢筋穿插在两个空心板梁间铰缝处；所述横向钢板与T字钢纵梁相连，并通过多个铆钉与两侧的空心板梁固定；施工工艺首先将T字钢直接由铰缝下方插入铰缝内；然后将钢筋张开；沿铰缝长度方向等间隔的安装T字钢和横向钢板，均布在板梁桥铰缝处，倒入混凝土；将横向钢板与T字钢纵梁相连，并通过铆钉与两侧的空心板梁固定。本发明提高了预制空心板桥铰缝的整体强度，从源头增强了板梁间的横向传力性能。
