Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of building structures, and in particular to a beam-column frame structure system. Background Art
[0002] With the increasing demand for building construction and construction technology, and increasingly stringent requirements for building layout, comfort, and reasonable quality of life, modern architecture has ushered in new technological changes in its structural systems. Modern buildings, especially high-rise buildings, are mostly frame structures, with beams and columns as the structural load-bearing columns. Therefore, strengthening the quality control of frame structure beams and columns and their joints plays a vital role in improving the overall seismic resistance, service life, and functional performance of the building.
[0003] During the construction of existing beams and columns, most steel bars are tied or welded to form a steel skeleton, then formwork is set up outside the steel skeleton, and finally concrete is poured. When connecting beams and columns, corresponding connecting structures are pre-embedded in the beam skeleton or mesh steel column skeleton. After the beams and columns are cast and formed, the pre-embedded connecting structures are assembled and connected, and concrete is poured at the joints. The construction of such beam-column structures requires a large amount of steel bar tying and welding work, which is relatively cumbersome.
[0004] Most of the prefabricated buildings currently available divide columns or beams into several prefabricated units, which are prefabricated in factories and then transported to the construction site for assembly and pouring connections. Although this method can improve construction efficiency, the quality of the bond between the new and old concrete needs to be considered after the different prefabricated units are spliced and poured. Not only does it need to ensure the bonding strength, but it also needs to avoid cracking at the bonding surface when the new and old concrete shrink, which makes the building's integrity poor.

DETAILED DESCRIPTION
[0041] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0042] Example 1 of the beam-column frame structure system of the present invention:
[0043] like Figure 1As shown, the beam-column frame structure system includes a beam body 1, a column body 2 and a beam-column connection node.
[0044] Among them, the column 2 includes a mesh steel column skeleton, such as Figure 2 As shown, the mesh steel column skeleton includes a mesh steel outer tube 6 and a mesh steel inner cage 5 arranged inside the mesh steel outer tube 6. Among them, the mesh steel outer tube 6 includes four outer mesh steel plates 7 welded end to end in the circumferential direction to form a rectangular frame structure, as shown in FIG. Figure 4 As shown, each outer mesh steel plate 7 is provided with a plurality of outer mesh holes 13 , and each outer mesh steel plate 7 is provided with an outer reinforcement area outside the outer mesh holes 13 , and a plurality of outer bolts 9 are provided on the outer reinforcement area.
[0045] The mesh steel inner cage 5 comprises four inner mesh steel plates 8 which are welded end to end in the circumferential direction to form a rectangular frame structure. Figure 5 As shown, each inner mesh steel plate 8 is provided with a plurality of inner mesh holes 14. The inner mesh holes 14 on the inner mesh steel plate 8 correspond one-to-one with the outer mesh holes 13 on the corresponding, parallel outer mesh steel plate 7. An inner reinforcement area is provided on the inner mesh steel plate 8 outside the inner mesh holes 14, and a plurality of inner pegs 10 are installed within the inner reinforcement area. In this embodiment, both the outer mesh holes 13 and the inner mesh holes 14 are oblong holes.
[0046] To prevent deformation of the mesh steel column skeleton during concrete pouring, in this embodiment, a plurality of column support ribs 11 are provided in the mesh steel outer tube 6 and spaced apart in the vertical direction, and a plurality of cage support ribs 12 are also provided in the mesh steel inner cage 5 and spaced apart in the vertical direction. The column support ribs 11 are distributed between the mutually parallel outer mesh steel plate 7 and the inner mesh steel plate 8, and the cage support ribs 12 are distributed between the two opposite inner mesh steel plates 8. Figure 2 As shown, the cage support rib 12 and the corresponding column support rib 11 are located on the same straight line.
[0047] Among them, Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the beam 1 comprises a mesh steel beam skeleton, which consists of four mesh steel beam plates spliced together in the circumferential direction to form a rectangular beam frame structure. Each mesh steel beam plate is provided with a plurality of beam mesh holes 15, each of which is an oblong hole. Each mesh steel beam plate has a beam structure reinforcement area outside the beam mesh holes 15, and is equipped with a plurality of beam studs 16 protruding from the mesh steel beam plate surface. A plurality of beam support ribs are provided between two opposing mesh steel beam plates.
[0048] Specifically, the four mesh steel beam plates are the front mesh steel beam plate 17, the rear mesh steel beam plate 18, the upper mesh steel beam plate 19, and the lower mesh steel beam plate 20. The beam support ribs include horizontal support ribs 21 and vertical support ribs 22. The horizontal support ribs 21 are arranged between the front mesh steel beam plate 17 and the rear mesh steel beam plate 18, and are arranged in multiple numbers at intervals along the left-right direction. The horizontal support ribs 21 extend in the front-to-back direction. The vertical support ribs 22 are arranged between the upper mesh steel beam plate 19 and the lower mesh steel beam plate 20, and are arranged in multiple numbers at intervals along the left-right direction. The vertical support ribs 22 extend in the up-down direction. The horizontal support ribs 21 and the vertical support ribs 22 are arranged alternately in the left-to-right direction. When pouring concrete, it can prevent the mesh steel beam skeleton from being squeezed and deformed by the concrete.
[0049] The front mesh steel beam slab 17, the rear mesh steel beam slab 18, and the upper mesh steel beam slab 19 are all provided with end reinforcement areas 23 at the left and right ends where bending moments are concentrated. The front mesh steel beam slab 17, the rear mesh steel beam slab 18, and the lower mesh steel beam slab 20 are all provided with a central reinforcement area 24 at the middle location where bending moments are concentrated. The distribution density of the beam mesh 15 within the end reinforcement areas 23 is less than the distribution density of the beam mesh 15 in other areas of the corresponding mesh steel beam slab, and the distribution density of the beam mesh 15 within the central reinforcement area 24 is less than the distribution density of the beam mesh 15 in other areas of the corresponding mesh steel beam slab. It should be noted that the distribution density of the beam mesh 15 refers to the sparseness of the beam mesh in the corresponding area. For example, there are fewer beam mesh 15 in the end reinforcement areas 23 and the central reinforcement area 24, while there are more beam mesh 15 in other areas. In this embodiment, a plurality of beam body studs 16 are welded at the end reinforcement areas 23 and the middle reinforcement area 24 . Of course, in other embodiments, the beam body studs may be replaced by beam body surface ribs.
[0050] It should be noted that in this embodiment, the end reinforcement areas 23 and the middle reinforcement area 24 are designed to improve the bending resistance of these areas by reducing the distribution density of the beam mesh 15. Of course, in other embodiments, the bending resistance can also be enhanced by increasing the thickness of the mesh steel beam plate in the end reinforcement areas 23 and the middle reinforcement areas 24. In this case, reinforcing ribs can be welded to the ends or middle of the mesh steel beam plate, where the bending moment is concentrated. Of course, in other embodiments, the end reinforcement areas 23 and the middle reinforcement areas 24 can also be omitted.
[0051] The beam mesh holes 15 are arranged in corresponding positions on the front and rear mesh steel beam plates 17 and 18, excluding the end reinforcement areas 23 and the middle reinforcement area 24. To facilitate the installation of the horizontal support ribs 21 and vertical support ribs 22, the horizontal support ribs 21 are inserted between corresponding beam mesh holes 15 on the front and rear mesh steel beam plates 17 and 18, and the ends of the horizontal support ribs 21 are welded to the walls of the corresponding beam mesh holes 15. The vertical support ribs 22 are inserted between corresponding beam mesh holes 15 on the upper and lower mesh steel beam plates 19 and 20, and the ends of the vertical support ribs 22 are welded to the walls of the corresponding beam mesh holes 15.
[0052] In this embodiment, it should be noted that the outer mesh 13 , the inner mesh 14 and the beam body mesh 15 are not limited to oblong holes, and rectangular holes, circular holes, oval holes and the like may also be used.
[0053] like Figure 1 、 Figure 3 、 Figure 10 and Figure 11 As shown, the beam connector 3 and the column connector 4 are both I-beams. The web of the column connector 4 is connected to the corresponding column support rib 11 as a whole, and the two wing plates of the column connector 4 are welded to the outer mesh steel plate 7 on the mesh steel outer tube 6. The beam connector 3 is partially located in the mesh steel beam skeleton, and the web of the beam connector 3 is connected to the corresponding vertical support rib 22 as a whole. The two wing plates of the beam connector 3 are respectively connected to the corresponding mesh steel beam plates by high-strength bolts 25. The beam connector 3 and the column connector 4 are in abutment and can be welded; the web of the beam connector 3 and the web of the column connector 4 are connected by a fixing plate 26 by high-strength bolts 25. The fixing plate 26 covers the gap between the webs of the two I-beams. There are two fixing plates 26, which are respectively located on the front and rear sides of the web of the I-beam.
[0054] Before construction, the present invention can prefabricate the mesh steel beam skeleton of the beam body 1 and the mesh steel column skeleton of the column body 2 in the factory. During construction, the mesh steel column skeleton is positioned and placed at the construction site, and the column connector 4 is connected to the mesh steel column skeleton, and the beam body connector 3 is connected to the mesh steel beam skeleton. Finally, the beam body connector 3 and the column connector 4 are assembled through the fixing plate 26 and the high-strength bolts 25, so that the mesh steel beam skeleton and the mesh steel column skeleton can be connected into a whole. Finally, the formwork is supported and cast to complete the construction of the beam-column frame.
[0055] Compared to existing construction methods, the beam-column frame structure of this invention avoids the problem of combining new and old concrete, allowing for integral casting. This results in greater beam-column integrity, a stronger load-bearing capacity, and more convenient construction. Furthermore, the use of a framework formed by splicing mesh steel plates as the frame for the columns and beams eliminates the need for lashing compared to a steel frame, simplifying the component manufacturing process. This fully utilizes the respective material properties of steel and concrete, resulting in high load-bearing capacity, high rigidity, and excellent seismic and shear resistance.
[0056] Example 2 of the beam-column frame structure system of the present invention:
[0057] The difference between this embodiment and the above embodiment 1 is that the structure of the column is different. Figure 12 As shown, in this embodiment, two mesh steel inner cages 5 are provided within the mesh steel outer cylinder 6, and are symmetrically arranged in the front-to-back direction. The columnar support ribs include multiple full-length support ribs 27, columnar transverse support ribs 28, and columnar longitudinal support ribs 29. The full-length support ribs 27 are located between two adjacent mesh steel inner cages 5 and connect the two corresponding outer mesh steel plates 7 of the mesh steel outer cylinder 6. The columnar transverse support ribs 28 are distributed on the front and back sides of the mesh steel inner cages 5, connecting each mesh steel inner cage 5 to the mesh steel outer cylinder 6 and between the mesh steel inner cage 5 and the full-length support ribs 27 in the front-to-back direction. The columnar longitudinal support ribs 29 are distributed on the left and right sides of the mesh steel inner cages 5, connecting each mesh steel inner cage 5 to the mesh steel outer cylinder 6 in the left-right direction.
[0058] The cage support ribs include cage transverse support ribs 30 and cage longitudinal support ribs 31 . The cage transverse support ribs 30 and the corresponding column transverse support ribs 28 are located on the same straight line, and the cage longitudinal support ribs 31 and the corresponding column longitudinal support ribs 29 are located on the same straight line.
[0059] Example 3 of the beam-column frame structure system of the present invention:
[0060] The difference between this embodiment and the above-mentioned embodiment 1 lies in the different structures and connection methods of the beam connectors and column connectors. Figure 13 As shown, the beam connector 301 and the column connector 302 are both square steel tubes. One end of the beam connector 301 is inserted into the mesh steel beam skeleton and connected to the corresponding mesh steel beam plate on the mesh steel beam skeleton through short high-strength bolts. The other end of the beam connector 301 is inserted into the column connector 302 and connected to the column connector 302 through multiple full-length high-strength bolts 303; the column connector 302 is welded to the mesh steel outer tube.
[0061] Example 4 of the beam-column frame structure system of the present invention:
[0062] The difference between this embodiment and the above-mentioned embodiment 1 lies in the different structures and connection methods of the beam connectors and column connectors. Figure 14As shown, the beam connector 401 and the column connector 402 are both node mesh steel plates 405, which are provided with a plurality of node mesh holes. Each node mesh steel plate 405 is provided with a node reinforcement area outside the node mesh holes, and the node reinforcement area is provided with a plurality of node studs 406 and / or a plurality of node surface ribs. The structure of the node mesh steel plate can be referred to Figure 4 The structure of the middle and outer mesh steel plates and Figure 5 The structure of the inner mesh steel plate differs only in the size of the plate and the number of mesh holes.
[0063] In order to reduce the welding process, the beam connecting parts can be integrally formed with the corresponding outer mesh steel plates during processing, and the column connecting parts can be integrally formed with the corresponding mesh steel beam plates.
[0064] The beam connector 401 and the column connector 402 are connected by bolts. Specifically, one of the beam connector 401 and the column connector 402 is embedded with a connecting bolt 403, and the other is provided with a through-hole 404 adapted to be plugged into the connecting bolt 403. When connecting, the connecting bolt 403 is directly inserted into the corresponding through-hole 404 to form a staggered connection structure.
[0065] Of course, in other embodiments, connection holes may be reserved on both the beam connector 401 and the column connector 402 . When connecting, the connection holes are aligned and inserted with ordinary bolts.
[0066] Of course, in other embodiments, the beam connector 401 and the column connector 402 can also be arranged in the same plane but at intervals. In this case, a connecting steel plate is provided on the outside of the beam connector 401 and the column connector 402, and the connecting steel plate covers the gap between the beam connector 401 and the column connector 402. The connecting steel plate here is a steel plate of a certain thickness with a smooth surface. Each connecting steel plate is connected to the corresponding column connector 402 by a short bolt of a relatively short length, and the two beam connectors are connected to the two connecting steel plates by a full-length bolt. Of course, the connecting steel plate can also be a connecting mesh plate, and the structure of the connecting mesh plate can refer to the structure of the node mesh plate.
[0067] The embodiments of the present invention described above do not limit the scope of protection of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the claims of the present invention.
