[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6 The present invention provides the following technical solution: a novel column-supporting beam structure, comprising a steel support beam 1, a cross steel column 2 fixed to the end of the steel support beam 1 by a strong bolt, a roof beam 3 fixed to the upper end of the cross steel column 2 by a bolt, an inclined support 4 fixed to the outer side of the end of the roof beam 3 by a bolt, and the end of the inclined support 4 away from the roof beam 3 being bolted to the steel support beam 1.

[0028] Furthermore, the diagonal supports 4 are symmetrically distributed about the longitudinal centerline of the roof beam 3. The diagonal supports 4 are made of double angle steel or channel steel. The diagonal supports 4 can improve the lateral stability of the roof beam 3 and also increase the connection reliability of the steel support beam 1.

[0029] Specifically, by fully utilizing the characteristics of the portal frame, a two-way portal frame is adopted, connecting the steel support beam 1 and the cross steel column 2 with high-strength bolts. This eliminates the need for on-site welding, reduces installation difficulty, and facilitates operation. It also improves the load-bearing capacity and longitudinal stiffness of the steel support beam 1. Depending on the needs, partial or complete column removal can be implemented to enhance the lateral stability of the roof beam 3. An inclined support 4 is directly added between the steel support beam 1 and the roof beam 3. The inclined support 4 typically uses double angle steel or channel steel, and the connection method is on-site bolt connection. Ordinary steel columns are designed according to conventional methods. The steel support beam 1 has a side steel column and a cross steel column 2. The steel support beam 1 uses an H-shaped cross section, with end plates and stiffening ribs welded to both ends. The inclined support 4 uses double angle steel or channel steel to connect with the steel support beam 1, improving the lateral stability of the roof beam 3 and also increasing the reliability of the connection of the steel support beam 1.

[0030] A roof beam 3 is bolted to the middle of the steel support beam 1. A reinforcing support assembly is provided at the installation point between the middle of the steel support beam 1 and the roof beam 3. The reinforcing support assembly includes a mounting seat 7 bolted to the lower side of the roof beam 3. A support seat 8 is installed at the lower end of the mounting seat 7. A sliding groove 9 is opened inside the support seat 8. A slider 10 is slidably connected inside the sliding groove 9. A reinforcing rod 11 is hinged to the lower end of the slider 10. A connecting ring 12 is hinged to the lower end of the reinforcing rod 11. A threaded rod 5 is threaded inside the connecting ring 12. A top plate 6 is sleeved on the upper end of the threaded rod 5, which allows the threaded rod 5 to rotate and move inside the connecting ring 12, pushing the top plate 6 to move.

[0031] Furthermore, the top plate 6 and the upper end of the threaded rod 5 form a rotating structure. The threaded rod 5 has a "T" shape, which allows the threaded rod 5 to continue rotating when the top plate 6 is in contact with the steel support beam 1, pushing the top plate 6 and the steel support beam 1 to fit tightly together and reinforce and support them. The shape of the slide groove 9 matches the shape of the slider 10. The slider 10 has an "I" shape and passes through the lower wall of the support seat 8, which can ensure the smooth movement of the slider 10 and prevent the slider 10 from falling off the support seat 8. The reinforcing rods 11 are distributed in an inclined manner and are symmetrically distributed about the longitudinal center line of the connecting ring 12. The reinforcing rods 11 are used to reinforce the connection between the steel support beam 1 and the roof beam 3.

[0032] Specifically, a reinforcing support assembly is added at the location of the column removal, that is, at the middle position of the steel support beam 1 away from the cross steel column 2. The middle position of the steel support beam 1 supports the roof beam 3. A mounting seat 7 is bolted to the lower side of the roof beam 3. A support seat 8 is installed at the lower end of the mounting seat 7, which can press down on the connecting ring 12, so that the connecting ring 12 controls the rotation of the outer hinged reinforcing rod 11. The reinforcing rod 11 controls the upper hinged slider 10 to slide in the slide groove 9 until the slider 10 is tightly attached to one side of the slide groove 9, so that the reinforcing rod 11 is inclined, and the relative movement of the slider 10 exerts a compressive force. The connection tightness of the roof beam 3 can be reinforced. With one hand, the connecting ring 12 is fixed, and with the other hand, the threaded rod 5 is rotated, so that the threaded rod 5 rotates and moves upward on the threaded connecting ring 12. When the top plate 6 at the upper end of the threaded rod 5 contacts the steel support beam 1, the upper end of the threaded rod 5 rotates inside the top plate 6. The threaded rod 5 can be rotated further to push the top plate 6 to move upward and fit tightly against the steel support beam 1. The connection between the steel support beam 1 and the roof beam 3 is reinforced by the inclined reinforcing rod 11 and the top plate 6. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although the utility model has been explained in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
