DETAILED DESCRIPTION

[0032] The technical solutions of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0033] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0034] Please refer to Figures 1 to 8 , the present application provides a kind of mixed roof bearing system, as Figure 1 It is shown that the system includes a plurality of concrete material column 100 spaced apart in array along transverse and longitudinal direction, steel frame beam 200 extends along transverse direction and is arranged on column 100, tie bar 300 extends along longitudinal direction and is connected with column 100 by first connecting assembly 10. Please continue to refer to Figures 2 to 4 , first connecting assembly 10 includes embedded part 11 embedded in column 100, the embedded part 11 includes embedded plate 111, anchoring rib 112 and anchoring piece 113. Embedded plate 111 is attached to the side of column 100, a plurality of anchoring ribs 112 are welded to the side of embedded plate 111 towards column 100, the end of each anchoring rib 112 away from embedded plate 111 is welded with anchoring piece 113, and each anchoring piece 113 is perpendicular to each anchoring rib 112.

[0035] In this embodiment, the embedded plate 111 forms a stable anchoring structure through the combination of anchor bars 112 and anchor pieces 113, so that the embedded plate 111 can remain stable when subjected to multi-directional stress, thereby preventing the embedded plate 111 from overturning. This design not only enhances the anchoring performance between the embedded plate 111 and the column 100, but also provides additional lateral support through the vertically arranged anchor pieces 113, further improving the overall stability and safety of the system. Specifically, the anchor bars 112 penetrate into the interior of the column 100 and work together with the anchor pieces 113 to ensure that the embedded plate 111 can still be stably fixed to the side of the column 100 under high load conditions, effectively preventing structural instability.

[0036] Further, each anchor piece 113 is connected with the corresponding anchor bar 112 and the anchor bar 112 and the embedded plate 111 through the way of perforated plug welding. Specifically, perforated plug welding makes the connection of the anchor bar 112 and the anchor piece 113 more firm, enhancing the overall anchoring performance. Specifically, perforated plug welding makes the welding points of the anchor bar 112 and the surrounding material tightly combined by opening a small hole at the connection and welding in the hole, forming a strong welded connection. Through this connection method, the strength and stability of the anchoring structure can be further improved, ensuring that there will be no loosening or breaking in long-term use, thereby greatly improving the reliability of the system. Especially when facing large amplitude vibration and impact, this connection method can still ensure the firmness and durability of the connection.

[0037] Optionally, the end plate 30 is welded at the end of the tie rod 300, the end plate 30 is perpendicular to the tie rod 300, the first connecting assembly 10 further includes the first connecting plate 12 protruding from the side of the embedded plate 111 away from the column 100, and the first matching plate 13 protruding from the side of the end plate 30 towards the embedded plate 111. The first connecting plate 12 and the embedded plate 111, and the first matching plate 13 and the end plate 30 are connected by angle welding respectively, the first connecting plate 12 and the first matching plate 13 are stacked in the transverse direction and connected by a plurality of bolts 31.

[0038] In this embodiment, the bolts 31 of the first connecting plate 12 and the first matching plate 13 connect the tie rod 300 and the column 100 stably. The angle welding method makes the connection between the parts of the connecting assembly more compact, which can ensure that the tie rod 300 can still be stably connected when bearing a large load, thereby improving the overall stability and safety of the system.

[0039] Further, the first connecting plate 12 and the first matching plate 13 are respectively provided with screw holes for the bolt 31 to pass through, the diameter of the screw hole is D, the diameter of the bolt 31 is d, and D-d is greater than or equal to 1mm. By setting the matching screw hole and the size of the bolt 31, reasonable gap control is realized, the hinged connection effect of the bolt 31 can be ensured, the fastening performance of the connecting assembly is improved, and thus the stability and safety of the overall structure are further enhanced.

[0040] Further, please refer to Figure 5 and Figure 6 , the tie rod 300 and the corresponding steel frame beam 200 are hinged through the second connecting assembly 20, specifically, the end of the tie rod 300 is welded with an end plate 30, the end plate 30 is perpendicular to the tie rod 300, the second connecting assembly 20 further includes a second connecting plate 21 protruding on the web plate 40 of the steel frame beam 200, and a second matching plate 22 protruding from the side of the end plate 30 towards the steel frame beam 200. The second connecting plate 21 and the web plate 40, and the second matching plate 22 and the end plate 30 are respectively connected by means of angle welding, the second connecting plate 21 and the second matching plate 22 are stacked in the transverse direction and connected by a plurality of bolts 31.

[0041] In this embodiment, the tie rod 300 and the steel frame beam 200 are firmly hinged together through the second connecting assembly 20. The angle welding makes the connection of the second connecting plate 21 and the second matching plate 22 more stable, and the bolt 31 makes the reliable hinge between the steel frame beam 200 and the tie rod 300, and can effectively avoid the problem of structural instability caused by loose connection.

[0042] Further, the second connecting plate 21 and the second matching plate 22 are respectively provided with screw holes for the bolt 31 to pass through, the diameter of the screw hole is D, the diameter of the bolt 31 is d, and D-d is greater than or equal to 1mm.

In this embodiment, the cross arrangement of the support rod 51 can effectively provide transverse support force to prevent the steel frame beam 200 from lateral deformation under stress, and further improve the overall stability of the system. Through this design, the anti-deformation ability of the steel frame beam 200 can be effectively enhanced without increasing the complexity of the system, thereby improving the stability and reliability of the load-bearing system.

[0044] Specifically, two basket bolts 52 are sleeved on each support rod 51 respectively, and the support rod 51 is pre-tightened by the two basket bolts 52. The pre-tightening design of the basket bolts 52 can adjust the tightness of the support rod 51, ensure that the support rod 51 maintains appropriate tension in the stressed state, and thus provide continuous and stable support force. In this way, by arranging the basket bolts 52 on the support rod 51 and controlling the tension of the support rod 51 by pre-tightening, it can be ensured that the support rod 51 always maintains the best stressed state during use. The adjustment function of the basket bolts 52 makes the installation of the support rod 51 more flexible, which can adapt to different stress conditions, thereby improving the adaptability and stability of the entire system.

[0045] Optionally, please continue to refer to 1 and Figure 8 The upper ends of the two outermost columns of columns 100 in the transverse direction are each spanned by a gutter beam 400, and the upper side of the gutter beam 400 is fixed with a gutter piece 60 formed by bending a stainless steel plate.
