Description

Technical Field

[0001] The utility model relates to the field of steel structures, in particular to an I-beam combined connecting piece. Background Art

[0002] I-beams are the most commonly used building materials in civil engineering. They are used as the main supporting material for temporary supports, cantilever scaffolding and other parts. I-beam connectors are used to connect I-beams. During the connection process, the stability of the I-beam connection needs to be ensured. When most I-beams are spliced, they are only connected and fixed by right-angle connecting blocks, that is, the right-angle connecting blocks are set at the right-angle bends formed by the butt joints of the I-beams, and the right-angle connecting blocks are fixed at the right angles by bolts to achieve the connection and fixation of the I-beams. However, the stability of a single connection through a right-angle connecting block is poor. The right-angle connecting block can only play a good role in left and right deflection force, and it is difficult to withstand up and down force, which can easily cause the bolts to break. Summary of the invention

[0003] The technical problem to be solved by the utility model is that the stability of the connection through a single right-angle connection block is poor, the right-angle connection block can only play a good left-right deflection force, and it is difficult to withstand the up-and-down force, which easily causes the bolt to break.

[0004] To solve the above problems, the technical solution adopted by the utility model is: an I-beam combination connector, including a first I-beam, a second I-beam, a C-shaped plate and a right-angle connecting plate, the number of the right-angle connecting plates is two and one of the right-angle sides of the two right-angle connecting plates is fixedly connected to the two sides of one end of the first I-beam by a first connecting bolt, the other right-angle sides of the two right-angle connecting plates are fixedly connected to the surface of one side of the second I-beam by a second connecting bolt, the C-shaped plate is clamped on the outer surface of the second I-beam and fixedly connected to the other side of the second I-beam by a third connecting bolt, and the upper and lower ends of the two right-angle connecting plates are in contact with the inner wall of the C-shaped plate.

[0005] The beneficial effect of the utility model is that the vertical splicing effect of the I-beams is achieved through the mutual cooperation of the C-shaped plates and the right-angle connecting plates, thereby ensuring the structural strength of the splicing locations of the I-beams.

[0006] As a further improvement of the utility model, the technical problem to be solved is: it is difficult to connect and fix I-beams of different thicknesses.

[0007] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the side walls of the C-shaped plate are respectively provided with strip-shaped adjustment grooves matching with the third connecting bolts, and the inner bottom surface and the inner top surface of the C-shaped plate are respectively provided with restraining parts matching with the first I-beam.

[0008] The beneficial effect of the above improvement is that by providing the strip-shaped adjustment groove, it is convenient to splice I-beams of different thicknesses, thereby achieving the effect of effectively fixing I-beams of different thicknesses.

[0009] As a further improvement of the utility model, the technical problem to be solved is: the I-beam is easy to deviate left and right.

[0010] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the constraint part includes an installation groove opened on the inner wall of the C-shaped plate and a bidirectional screw rod rotatably arranged in the installation groove, and two constraint plates are symmetrically slidably arranged in the installation groove, and threaded holes matching the bidirectional screw rod are opened in the middle of the two constraint plates, and one end of the bidirectional screw rod passes through the outside of the installation groove and is provided with an operating handle.

[0011] The beneficial effect of the above improvement is that by setting the constraint plate, the constraint plate and the inner side of the first I-beam are in contact with each other, thereby effectively preventing the first I-beam from causing the second I-beam to deviate left and right as a whole.

[0012] The utility model further improves the technical solution adopted as follows: reinforcing ribs are fixedly arranged at the middle parts of the two right-angle connecting plates.

[0013] The beneficial effect of the above improvement is: by providing reinforcing ribs, the structural strength of the right-angle connecting plate is further guaranteed, deformation of the right-angle connecting plate is effectively avoided, and the verticality of the splicing of the first I-beam and the second I-beam is guaranteed.
