Connecting structure of inverted-T-shaped bent cap and main beam
The invention relates to a connecting structure of an inverted-T-shaped bent cap and a main beam, and relates to the technical field of bridge construction. A pouring space is formed between the inverted-T-shaped bent cap and the main beam; the connecting structure comprises a pavement layer, a tensile layer and a transition layer, wherein the pavement layer is paved on the main beam; the tensile layer is used for being filled in the pouring space, and the top end of the tensile layer is connected with the pavement layer; the transition layer is used for being filled in the pouring space, the top end of the transition layer is connected with the bottom end of the tensile layer, and the bottom end of the transition layer is used for being pressed on the inverted-T-shaped bent cap; a gap is formed in the transition layer, and one end of the gap extends to the top end of the transition layer. The gap is formed in the transition layer, stress is concentrated to the gap in advance, the transition layer can be firstly damaged in the process that the main beam is pulled and deflected, the structure of the main beam is not affected by damage of the transition layer, and thus the transition layer plays a role in protecting the main beam.
本申请涉及一种倒T型盖梁与主梁的连接结构，涉及桥梁施工技术领域，该倒T型盖梁与主梁之间形成有浇筑空间；该连接结构包括铺装层、抗拉层和过渡层，铺装层用于铺设于主梁上；抗拉层用于填充于浇筑空间内，且抗拉层的顶端与铺装层连接；过渡层用于填充于浇筑空间内，过渡层的顶端与抗拉层的底端连接，底端用于压持于倒T型盖梁上；且过渡层上开设有缝隙，缝隙的一端延伸至过渡层的顶端。在过渡层上开设缝隙，预先将应力集中至缝隙处，在主梁受拉偏转过程中，会最先损坏过渡层，而过渡层的损坏对主梁的结构没有影响，因此过渡层起到保护主梁的作用。
