Description

Technical Field

[0001] The utility model relates to the technical field of composite beam steel plate connection, in particular to a steel plate connecting piece of an assembled composite beam. Background Art

[0002] A beam made of two different materials or different processes is called a composite beam, also known as a combined beam. Some main beams are made of one material, while the bridge deck connecting the main beams is made of another material; there are also composite beams made of I-beams or prestressed concrete beams and reinforced concrete bridge decks cast in situ.

[0003] Most of the existing composite beams contain steel plates to strengthen the bearing capacity and overall strength of the composite beams. During the use of the composite beams, the steel plates will be close to each other, and operators will use connectors or direct welding to connect them. The use of connectors is more cumbersome, but can be disassembled according to actual conditions in the subsequent process to adjust the composite beams. The welding connection is reliable but is a permanent connection method, which is inconvenient for adjustments that may be made at any time and subsequent maintenance and repairs.

[0004] Existing connectors can only connect steel plates firmly, but the corners of the steel plates may bend to varying degrees due to steel plate stress, transportation, production and other reasons. The bent parts of the steel plates are prone to warping during subsequent concrete pouring, which may increase the amount of concrete required and even make the concrete uneven after drying. Utility Model Content

[0005] The purpose of the utility model is to solve the following problems existing in the prior art:

[0006] When connecting steel plates, connectors can only ensure a firm connection between the steel plates. However, the corners of the steel plates may bend to varying degrees due to steel plate stress, transportation, and production. The bent parts of the steel plates are prone to warping during subsequent concrete pouring, which may increase the amount of concrete required and even cause the concrete to be uneven after drying.

[0007] In order to solve the problems existing in the prior art, the utility model provides a steel plate connecting part of an assembled composite beam, including a bottom plate and a top plate arranged opposite to the bottom plate, a partition is arranged on the surface of the bottom plate and the top plate facing each other, a central threaded rod is arranged on the top of the partition located on the surface of the bottom plate, placement holes are opened on the surfaces of the top plate and the bottom plate, a through threaded rod is threadedly connected inside the placement hole, and nuts are arranged on the surfaces of the through threaded rod and the center threaded rod.

[0008] The utility model provides a steel plate connector for an assembled composite beam.

[0009] Furthermore, the partition is a cross-shaped plate structure, a central threaded rod is provided at the center position of the top of the partition located on the bottom plate surface, and a through hole adapted to the central threaded rod is opened at the center position of the partition located on the top plate surface.

[0010] Furthermore, the placement holes are located on one side of the top plate and the bottom plate close to the partition and penetrate the partition.

[0011] Furthermore, the through-threaded rod passes through the bottom plate, the partition plate and the top plate in sequence along the placement hole, and both ends of the through-threaded rod extend to the outside of the bottom plate and the top plate respectively.

[0012] Furthermore, a slot adapted to the nut is provided on one side of the bottom plate close to the placement hole.

[0013] Furthermore, the top plate and the bottom plate are both rectangular plate structures, and the interior thereof is divided into four independent areas by partitions.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model forms four independent rectangular areas on the opposite sides of the bottom plate and the top plate by arranging partitions thereon. When in use, the bottom plate is first aligned with the corners of the steel plate, and it is ensured that the central threaded rod at the top of the bottom plate is aligned with and passes through the gap between the steel plate. Then the top plate is sleeved on the outside of the central threaded rod, and the top plate is fixed with nuts. At this time, the top plate and the bottom plate are fixed on both sides of the steel plate. Then the threaded rod is inserted along the placement hole and nuts are placed at both ends of the threaded rod. The operator can rotate the nuts at both ends of the threaded rod to bring the top plate and the bottom plate closer to each other, squeeze the warped position of the steel plate to restore it to a horizontal state during the movement of the top plate or the bottom plate, and the threaded rods extending to the outside at both ends of the top plate and the bottom plate can be used as anchor rods to enhance the structural strength during the subsequent concrete pouring process.
