| description | The invention provides a bridge expansion device for bridge construction, and belongs to the technical field of bridge construction.The top of a limiting block is movably connected with a first extension threaded shaft, the left side and the right side of the limiting block are both fixedly connected with horizontal instruments, and a first sliding groove is formed in the top of a sliding frame; the interior of the first sliding groove is slidably connected with an extension supporting block, and the interior of the extension supporting block is in threaded connection with a second extension threaded shaft. A first extending threaded shaft can be rotated by rotating a cross-shaped rotating handle, and the sliding frames can slide inwards or outwards by rotating the first extending threaded shaft, so that the second sliding grooves can enable the sliding frames to stably slide in the second sliding grooves, and the distance between the two sliding frames can be adjusted; the second extension threaded shaft can |
