[0043] Embodiment 1
[0044] As Figures 1-6 shown, a steel skeleton includes a beam steel skeleton 11, a column steel skeleton 12 and a beam-column joint member 13. The beam steel skeleton 11 and the column steel skeleton 12 are connected through the beam-column joint member 13. Among them, the beam steel skeleton 11 can be arranged horizontally and connected to the side surface of the beam-column joint member 13, and the column steel skeleton 12 can be arranged vertically and connected to the top surface and the bottom surface of the beam-column joint member 13. This steel skeleton 1 can independently serve as a lateral force resisting system of a building structure (such as a frame structure), or can be combined with other structural systems to form a combined lateral force resisting system (such as a frame-core tube structure).
[0045] Among them, as Figures 3-4 shown, both the beam steel skeleton 11 and the column steel skeleton 12 have flanges 15 and webs 16. The webs 16 of the beam steel skeleton 11 and the column steel skeleton 12 are each provided with holes 14 for passing through tie bars 23 at intervals along their respective length directions.
[0046] By opening holes 14 in the webs 16 of the beam steel skeleton 11 and the column steel skeleton 12, when arranging steel bars outside the steel skeleton 1, the tie bars 23 for fastening the longitudinal steel bars 21 of the steel bars can directly pass through the holes 14, reducing or even avoiding the obstruction of the beam steel skeleton 11 and the column steel skeleton 12 to the steel bar arrangement. Thus, the convenience and efficiency of the steel bar construction process are improved; at the same time, the arrangement area of the steel bars extends deep into the steel skeleton, improving the tightness of the distribution of the steel bars in the concrete 3. Thus, the bearing capacity of the steel reinforced concrete 3 structure is improved; at the same time, the steel skeleton can also support and restrict some of the tie bars 23 passing through its holes 14, making the steel bars more stable in the steel skeleton, further improving the bearing capacity of the steel reinforced concrete 3 structure.
[0047] Among them, the hole 14 can be rectangular. The length direction of the rectangle is perpendicular to the length direction of the beam steel skeleton 11 or the column steel skeleton 12. The length of the rectangle is 100 - 600 mm, and the width of the rectangle is 50 - 200 mm. If the strength of the beam steel skeleton 11 or the column steel skeleton 12 meets the requirements, the width of the rectangle can be made greater than the length. This facilitates multiple tie bars 23 to pass through the holes 14 simultaneously, further reducing or even avoiding the obstruction of the beam steel skeleton 11 and the column steel skeleton 12 to the steel bar arrangement.
[0048] For the structure of the beam steel skeleton 11, it can be: as Figure 3 shown, the beam steel skeleton 11 has two flanges 15, and the cross-section of the web 16 of the beam steel skeleton 11 is in a straight shape. The two flanges 15 are distributed at corresponding positions on the web 16 of the beam steel skeleton 11, that is, on both sides of the web 16.
[0049] For the structure of the column steel skeleton 12, it can be: as Figure 10 shown, the column steel skeleton 12 has two flanges 15, and the cross-section of the web 16 of the column steel skeleton 12 is in a straight shape. The two flanges 15 are distributed at corresponding positions on the web 16 of the column steel skeleton 12, that is, on both sides of the web 16; it can also be: as Figure 9 shown, the column steel skeleton 12 has four flanges 15, and the cross-section of the web 16 of the column steel skeleton 12 is in a cross shape. The four flanges 15 are distributed at corresponding positions on the web 16 of the column steel skeleton 12, that is, on the outside of the four plate members formed by the cross shape of the web 16.
[0050] Based on the fact that the hole 14 is rectangular, for the convenience of forming the hole 14, it can be achieved by directly connecting and forming existing steel sections or metal components through welding.
[0051] On this basis, for the beam steel skeleton 11, in one or more embodiments, as Figure 3 shown, the beam steel skeleton 11 includes two T-shaped steel sections 17 and a plurality of flat steel sections 18; the two T-shaped steel sections 17 are parallel to each other, and the webs 16 of the two T-shaped steel sections 17 are arranged opposite to each other; the plurality of flat steel sections 18 are located between the two T-shaped steel sections 17 and are arranged at intervals along the length direction of the T-shaped steel sections 17. The two ends of each flat steel section 18 are respectively connected to the web 16 of the corresponding side T-shaped steel section 17 by welding, and a rectangular hole 14 of the beam steel skeleton 11 is formed at intervals between the flat steel section 18 and the T-shaped steel section 17.
[0052] At the same time, for the column steel skeleton 12, when the column steel skeleton 12 includes two flanges 15 and the cross-section of the web 16 of the column steel skeleton 12 is in a straight shape, the structure of the column steel skeleton 11 is similar to that of the beam steel skeleton 11, and it can also be composed of two T-shaped steel sections 17 and a plurality of flat steel sections 18 welded together.
[0053] In addition, for the column steel skeleton 12, when the column steel skeleton 12 includes four flanges 15 and the cross-section of the web 16 of the column steel skeleton 12 is in a cross shape, in one or more embodiments, as Figure 4 shown, the column steel skeleton 12 includes four T-shaped steel sections 17, a plurality of flat steel sections 18 and a cross-shaped steel section 19; the four T-shaped steel sections 17 are parallel to the cross-shaped steel section 19, and the four T-shaped steel sections 17 correspond one by one to the four plate-like structures of the cross-shaped steel section 19, and the web 16 of the T-shaped steel section 17 is arranged opposite to the corresponding plate-like structure; the plurality of flat steel sections 18 are divided into four groups, and the four groups of flat steel sections 18 correspond one by one to the four T-shaped steel sections 17. Each group of a plurality of flat steel sections 18 are respectively located between the corresponding T-shaped steel section 17 and the cross-shaped steel section 19 and are arranged at intervals along the length direction of the corresponding T-shaped steel section 17. The two ends of each flat steel section 18 are respectively connected to the corresponding T-shaped steel section 17 and the plate-like structure by welding, and a rectangular hole 14 of the column steel skeleton 12 is formed at intervals between the cross-shaped steel section 19, the flat steel section 18 and the T-shaped steel section 17.
[0054] At this time, for the beam steel skeleton 11 and the column steel skeleton 12, compared with the processing method of directly cutting out the hole 14 in the I-shaped steel skeleton and / or cross-shaped steel skeleton in the prior art, the processing method of directly connecting and forming existing steel sections or metal components through welding in this application is more convenient, and reduces or even eliminates the scraps cut off during the processing, thereby reducing the manufacturing cost of the beam steel skeleton 11 and the column steel skeleton 12.
[0055] The width of the flat steel 18 can be 50mm-150mm, the height can be 100-600mm, and it can be butt-welded with other existing steel sections or metal components (T-section steel or cross-section steel). The arrangement spacing of the flat steel 18 is 50-200mm.
[0056] Among them, for the column steel frame 12, it is preferred that half of the width of the flange 15 is smaller than the sum of the width of the single plate structure of the cross-shaped steel 19 and the length of the flat steel 18 to avoid the flange 15 blocking the reinforcement 23 from passing through the hole 14.
[0057] For the beam-column node member 13, in one or more embodiments, as Figure 5 As shown, the beam-column node member 13 may be a solid-web steel member.
[0058] The solid-web steel member refers to a steel member in which the web 16 is solid. At this time, the solid-web steel member is connected by welding of steel plates, which can effectively ensure the shear bearing capacity of the node area.
[0059] When it is necessary to penetrate steel bars that match the steel skeleton 1, small holes for the steel bars to pass through can be opened on the steel plate of the beam-column node component 13. The diameter of the small hole is adapted to the steel bar, thereby minimizing the impact of the arrangement of the small hole on the bearing capacity of the beam-column node component 13.
[0060] The beam-column node member 13 is connected to the beam steel frame 11 and the column steel frame 12 by welding.
[0061] Regarding the structure of the beam-column node member 13, in one or more embodiments, the beam-column node member 13 includes a center piece 131, a side plate 132, and an end plate 133;
[0062] The cross-sectional shape of the center piece 131 along the direction perpendicular to the length of the column steel frame 12 is adapted to the cross-sectional shape of the web 16 of the column steel frame 12. For example, when the web 16 of the column steel frame 12 is in a straight line, the center piece 131 is also in a straight line, or, when the web 16 of the column steel frame 12 is in a cross shape, the center piece 131 is also in a cross shape. A plurality of the side panels 132 are connected to the center piece 131, and the positions of the plurality of the side panels 132 on the center piece 131 correspond to the positions of the flanges 15 in the column steel frame 12 on the web 16, so that the cross-sectional shapes of the side panels 132 and the center piece 131 are adapted to the cross-sectional shape of the column steel frame 12; each of the side panels 132 can be simultaneously connected to the flange 15 and the web 16 of a single beam steel frame 11;
[0063] A plurality of the end plates 133 are respectively connected to the top and bottom ends of the central member 131 and the plurality of side plates 132. The end plates 133 at the top and bottom ends can be respectively connected to the flanges 15 and webs 16 of the corresponding column steel section 12 simultaneously.
[0064] When the column steel section 12 includes four flanges 15 and the cross-section of the web 16 of the column steel section 12 is cross-shaped, specifically, as Figure 5 shown, the beam-column joint member 13 may include a central member 131, four side plates 132 and two end plates 133; the central member 131 has four central plates, and the inner sides of the four central plates are connected together, so that the cross-sectional shape of the central member 131 is cross-shaped; the four side plates 132 respectively correspond to the four central plates, the side plates 132 are respectively connected to the outer sides of the corresponding central plates, and each side plate 132 can be connected to the flange 15 and the web 16 of a single beam steel section 11 simultaneously; the two end plates 133 are respectively located at both ends of the four central plates and the four side plates 132, and each end plate 133 is connected to the corresponding ends of the four central plates and the four side plates 132 simultaneously, and each end plate 133 can be connected to the flange 15 and the web 16 of the column steel section 12 simultaneously.
[0065] The beam-column joint member 13 under this structure has sufficient bearing capacity. At the same time, if it is necessary to drill holes in the beam-column joint member 13 for passing through the longitudinal bars 21 adapted to the beam or column, the holes can be directly drilled on the plate members such as the side plates 132 or the end plates 133, which is convenient for the arrangement of the steel bar framework 2.
[0066] On this basis, in order to facilitate the alignment connection between the beam-column joint member 13 and the beam steel section 11, a steel section structure adapted to the beam steel section 11 can be prefabricated on the outer side of the side plate 132 in advance. When connecting the beam-column joint member 13, the steel section structure can be directly aligned with the beam steel section 11 and welded.
[0067] Embodiment 2
[0068] A steel reinforced concrete structure system, such as Figures 7-10As shown, it includes concrete 3, a steel bar framework 2, and a steel skeleton as described in any one of Embodiment 1. The concrete 3 wraps outside the steel bar framework 2 and the steel skeleton 1. The steel bar framework 2 includes longitudinal bars 21 and stirrups. The longitudinal bars 21 and the stirrups cooperate to form a steel bar mesh that cooperates with the steel skeleton 1. The stirrups include hoop stirrups 22 and tie bars 23. The hoop stirrups 22 surround the outside of the steel skeleton 1. The tie bars 23 pass through the holes 14, and both ends of the tie bars 23 are respectively connected to the longitudinal bars 21 located on both sides of the holes 14. At this time, through the cooperation of the tie bars 23 and the holes 14, the stirrups of the steel bar framework 2 can form a structure that can be inserted into the cross-shaped composite stirrups, facilitating the construction of the steel bar framework 2 on the steel skeleton 1, making the arrangement of the steel bar framework 2 more convenient. At the same time, the density of the stirrup arrangement is increased, and the strength of the steel bar framework 2 is improved.
[0069] Among them, one, two, three, or even more tie bars 23 can be inserted through the holes 14 of the beam steel skeleton 11. As Figure 8 shown, three tie bars 23 are inserted through the holes 14 of the beam steel skeleton 11.
[0070] One, two, three, or even more tie bars 23 can be inserted through the holes 14 of the column steel skeleton 12. As Figure 9 shown, one tie bar 23 is inserted through each hole 14 of the column steel skeleton 12; as Figure 10 shown, two tie bars 23 are inserted through each hole 14 of the column steel skeleton 12.
[0071] Among them, the cross-section of the concrete 3 wrapped outside the beam steel skeleton 11 or the column steel skeleton 12 is preferably a rectangular structure.
[0072] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
