Underneath-buried shallow-buried bridge expansion device
The invention belongs to the field of bridge construction, and particularly discloses a buried shallow-buried bridge expansion device which is characterized in that a web plate of a middle beam is provided with a connecting hole for a cross beam to penetrate through, the cross beam is welded with the middle beam after penetrating through the connecting hole, and a middle beam reinforcing plate is fixed to the lower end of the middle beam and located under the cross beam; the upper end of the supporting box is lower than the upper end of the middle beam, a limiting hole is formed in the position, located on the upper elastic supporting piece, of the upper end of the supporting box, the upper end of the upper elastic supporting piece is inserted into the through hole and limited by the inner wall of the limiting hole, and a cover plate used for sealing the limiting hole is fixed to the upper end of the supporting box. And the upper end of the cover plate is lower than the upper end of the middle beam. By the adoption of the scheme, the problem that the telescopic device is not suitable for the thin-wall beam body due to the large height can be solved.
本发明属于桥梁施工领域，具体公开了一种下埋式浅埋型桥梁伸缩装置，中梁的腹板上开设有供横梁穿过的连接孔，横梁穿过连接孔后和中梁焊接，中梁下端固定有中梁加强板，中梁加强板位于横梁的正下方；支撑箱上端的位置高度低于中梁上端的位置高度，支撑箱上端位于上弹性支撑件处开设有限位孔，上弹性支撑件的上端插入通孔内并受到限位孔内壁的限位，支撑箱上端固定有用于封闭限位孔的盖板，盖板上端的位置高度低于中梁上端的位置高度。采用本发明的方案，可以解决伸缩装置的高度较高不适用于薄壁梁体的问题。
