Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a standardized plate-column node. Background Art

[0002] "Industrial Upstairs" refers to a new industrialization model that shifts industrial production from traditional factory buildings to high-rise buildings. Through vertical layout and resource sharing, it conserves land and improves resource efficiency. This new industrialized building model requires flexible spatial layouts and high requirements for column spacing, floor height, and load capacity.

[0003] Existing structural systems suitable for this type of building include cast-in-place crisscross beam floor slabs and frame columns, reinforced truss floor decks, H-shaped steel beams, steel tubular columns or concrete-filled steel tubular columns, and prestressed hollow-core floor slabs, H-shaped steel beams, steel tubular columns or concrete-filled steel tubular columns. However, these structures all present certain challenges.

[0004] Cast-in-place crisscross beam floor-frame column structures are widely used in large industrial buildings due to their uniform load distribution and economical efficiency. However, the most significant drawback of this structural system lies in its traditional construction method, which relies on extensive on-site formwork. This not only prolongs the construction period and increases labor costs, but also conflicts with the prefabricated construction philosophy advocated by the modern construction industry. As the construction industry's requirements for construction speed and environmental protection increase, the limitations of cast-in-place crisscross beam floor-frame column structures are becoming increasingly apparent. This is particularly true in "industrial building" projects that pursue high efficiency and sustainable development, limiting their application.

[0005] The reinforced truss floor deck, H-beam steel beam, and steel tubular or concrete-filled steel tubular columns structure has been widely used in modern steel structures due to its efficient construction and excellent seismic performance. This structural system requires virtually no formwork or support on site, significantly increasing construction speed and reducing complexity. However, the design of this structural system also presents new challenges. For example, the combination of primary and secondary beams results in a larger main beam cross-section, which not only affects the efficiency of internal building space utilization but also limits floor height, making it unsuitable for industrial production activities requiring high headroom. Furthermore, it consumes a large amount of steel, resulting in high costs.

[0006] The prestressed hollow slab-H-shaped steel beam-steel tube column or steel tube concrete column structure performs well in multi-story and high-rise buildings due to its light weight, high strength and convenient construction. This structural system is particularly suitable for column grid arrangements with large differences in length-to-width ratios, which can effectively reduce the deadweight of the slab and improve the overall performance of the structure. However, for "industrial upstairs" projects, the column grid layout is usually evenly distributed, which means that if a prestressed hollow slab structure is used, the unidirectional stress characteristics of the slab may reduce economic efficiency and increase unnecessary costs. In addition, similar to the first two structural systems, the prestressed hollow slab-H-shaped steel beam-steel tube column or steel tube concrete column structure also faces the problem of large steel consumption, which puts pressure on controlling project costs. Utility Model Content

Since the upper side of the floor slab is fixedly connected to the upper through-partition plate, the other end of the top bar also extends toward the center of the floor slab, and its extension length is 1 / 3 of the clear span of the column (the extension length refers to the length of the top bar extending from the edge of the upper through-partition plate).

The plate reinforcement in the solid slab area is welded on-site with the upper and lower through-partitions, which can effectively transmit the bending moment of the floor slab.

DETAILED DESCRIPTION

[0026] The present invention will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the present invention are within the scope of protection of the present invention.

[0027] The utility model provides a standardized plate-column joint, see Figure 1, comprising an upper steel pipe column 1, a lower steel pipe column 2, a reinforcing steel pipe column 3, an upper through-partition 4, a lower through-partition 5 and a shear plate 8. The upper steel pipe column is arranged in the vertical direction, and its lower end is fixedly connected to the upper surface of the upper through-partition 4; the reinforcing steel pipe column is located below the upper through-partition, and the lower surface of the upper through-partition is fixedly connected to the upper end of the reinforcing steel pipe column, and the lower end of the reinforcing steel pipe column is fixedly connected to the upper surface of the lower through-partition 5; the lower surface of the lower through-partition is fixedly connected to the upper end of the lower steel pipe column. A plurality of overlapping longitudinal bars 6 are provided in the reinforcing steel pipe column. The overlapping longitudinal bars are arranged along the length direction of the reinforcing steel pipe and are evenly distributed along the circumferential interval of the cross section of the reinforcing steel pipe column. The upper end of the overlapping longitudinal bar passes through the upper through-partition and continues to extend into the upper steel pipe column, and the lower end passes through the lower through-partition and continues to extend into the lower steel pipe column. A plurality of shear plates 8 are provided between the upper through-partition and the lower through-partition. Two adjacent shear plates are located on the outside of the adjacent two side walls of the reinforced steel pipe column, and the length directions of the two adjacent shear plates are perpendicular to each other. The adjacent sides of the two adjacent shear plates are fixedly connected to the outer side walls of the adjacent two sides of the reinforced steel pipe column respectively. The upper end of the shear plate extends to the bottom of the upper through-partition and is fixedly connected to it, and the lower end of the shear plate extends to the top of the lower through-partition and is fixedly connected to it. The shear plate between the upper through-partition and the lower through-partition further enhances the lateral bearing capacity of the node, enabling the shear plate to effectively transmit the vertical force from the floor slab. The lap longitudinal reinforcement passes through the entire node and is anchored into the upper and lower steel pipe columns, making the force transmission simple and reliable. At the same time, since the length directions of the two adjacent shear plates are perpendicular to each other and are fixedly connected to the outer side walls of the reinforced steel pipe column, this enhances the bearing capacity and deformation capacity of the node under complex stress conditions. At the same time, due to the complex forces acting in the core area of ​​the joint (i.e., the area between the upper and lower partitions), this area requires local reinforcement. Shear plates can be installed to transfer the vertical shear forces of the floor slab to the concrete-filled steel tubular columns. Separate, standardized reinforced steel tubular columns also provide local reinforcement in this area. Multiple reinforcing members are installed within each upper and lower steel tubular column, fixedly connected to the columns. The reinforcing members within each column correspond to each other. Both columns are thin-walled.

[0028] In some embodiments of the present invention, in the upper steel pipe column, the reinforcing member is an upper diagonal rib 7, see Figures 1 and 2The upper diagonal rib is located between the adjacent side walls of the upper steel pipe column. It is arranged along the length of the upper steel pipe column. Its opposite sides are fixedly connected to the adjacent inner side walls of the upper steel pipe column. A gap exists between the surface of the upper diagonal rib facing the center of the upper steel pipe column and the overlapping longitudinal reinforcement. The lower end of the upper diagonal rib extends above the upper through-partition and abuts against its upper surface. A certain gap is left between the upper diagonal rib and the overlapping longitudinal reinforcement. A certain thickness of concrete is poured into this gap. The upper diagonal rib transfers force to the concrete, which in turn transfers force to the overlapping longitudinal reinforcement. This indirect force transmission method facilitates processing and achieves the purpose of continuous force transmission. The same is true for the lower steel pipe column. In the lower steel pipe column, the reinforcing member is a lower diagonal rib. The lower diagonal rib is located between the adjacent two side walls of the lower steel pipe column. The lower diagonal rib is arranged along the length direction of the lower steel pipe column. The opposite sides of the lower diagonal rib are fixedly connected to the two adjacent inner side walls of the lower steel pipe column. There is a gap between the side surface of the lower diagonal rib facing the center of the lower steel pipe column and the overlapping longitudinal reinforcement. The upper end of the lower diagonal rib extends to the bottom of the lower through-partition and abuts against its lower side surface. A certain thickness of concrete is also poured in this gap, and the force transmission process is consistent with the force transmission process in the upper steel pipe column. The upper and lower diagonal ribs are respectively arranged in the upper and lower steel pipe columns, mainly to strengthen the thin-walled steel pipe column, ensure premature buckling of the steel pipe part, and enhance the constraint of the steel pipe on the internal concrete, thereby improving the bearing capacity and ductility of the column.

[0029] The utility model is a study on the further application of thin-walled steel tube columns, wherein the cross-sectional size of ordinary rectangular or square steel tube concrete columns should not be less than 400mm, the thickness of the steel tube should not be less than 8mm, and the ratio of the width to the thickness of the steel tube should not be greater than the limit value of 60×(235 / f ak )0.5, where f akThe thin-walled steel pipe column mentioned in the utility model refers to a steel pipe concrete column with a ratio of width to thickness of steel pipe in the column exceeding the limit value and a steel ratio of 4% to 5%. The thin-walled steel pipe column has a good application prospect due to a low steel consumption, but the stiffened thin-walled steel pipe concrete column and the detachable bottom mold steel truss hollow slab have not been found to be used in actual engineering. The stiffened thin-walled steel pipe concrete column and the detachable bottom mold steel truss hollow slab form a beamless slab column structure, field formwork is free, meets the demand of fabricated construction, the hollow floor slab has large rigidity, the floor system has light self weight, is suitable for being made into a two-way slab, does not need main and secondary beams, has large floor net height, has flexible architectural layout, and is suitable for the case that the column distance of two directions of the "industrial upbuilding" building is close. The floor slab concentrates all loads to the column, so the slab-column joint of the structure is the key of the structure system, in order to make the joint reliable in force transmission, convenient for factory processing, convenient for field installation and reduce comprehensive cost, a standardized slab-column joint is provided. The utility model designs a new standardized slab-column joint, considering that the stress at the connection position of the floor slab and the column is large and complex, so when the joint is actually applied, especially when the joint is connected with the floor slab, the area where the floor slab and the column are connected can adopt a solid slab, the remaining area adopts a hollow slab, the slab reinforcement in the solid slab is welded with the upper and lower through partitions on site, can effectively transmit the floor slab bending moment; a shear plate is arranged between the upper and lower through partitions, is used for transmitting the vertical shear force of the floor slab, at the same time, the upper and lower partitions are replaced by a standard reinforced steel pipe column, the shear plate is welded into an integral whole, enhances the bearing and deformation capacity of the joint; the lap longitudinal reinforcement passes through the standard joint and is anchored into the upper and lower columns, transmits force through lap joint, is simple and reliable, can effectively solve the problem that the closed space opening diagonal rib cannot be welded, so that the force cannot be continuously transmitted, and facilitates construction.

[0030] In some embodiments of the utility model, a plurality of top reinforcements 9 are arranged above the upper through partition, see Figure 4The top reinforcement is laid in the horizontal direction, one end of which is located above the edge of the upper through-partition and fixedly connected to it, and the other end of which continues to extend in the direction away from the upper through-partition. In actual application, the top reinforcement is distributed at intervals along the circumference of the upper steel pipe column, one end of which is located above the edge of the upper through-partition and fixedly connected to the upper surface of the edge of the upper through-partition by welding, and the other end of which continues to extend in the direction away from the upper through-partition. Since the upper side of the floor slab is fixedly connected to the upper through-partition, the other end of the top reinforcement also extends in the direction of the center of the floor slab, and its extension length is 1 / 3 of the clear span of the column (the extension length refers to the length of the top reinforcement extending from the edge of the upper through-partition). A plurality of bottom reinforcements 10 are laid above the lower through-partition. The bottom reinforcement is laid in the horizontal direction, one end of which is located above the edge of the lower through-partition and fixedly connected to the upper surface of the edge of the lower through-partition by welding, and the other end of which continues to extend in the direction away from the lower through-partition. In actual application, the bottom reinforcement is spaced along the circumference of the reinforced steel pipe column. One end is welded to the upper surface of the edge of the lower through-diaphragm, and the other end continues to extend away from the lower through-diaphragm. Because the lower side of the floor slab is fixed to the lower through-diaphragm, the other end of the bottom reinforcement also extends toward the center of the floor slab. Its extension length is the same as the column span, that is, the other end of the bottom reinforcement extends to the steel pipe column on the opposite side of the floor slab. The top reinforcement effectively transmits the negative bending moment of the floor slab, while the bottom reinforcement resists the positive bending moment of the slab-column joint under reciprocating earthquakes. Together, the two form a hidden beam, ensuring that the load of the floor slab is effectively transferred to the columns, thereby making the structure safer.

[0031] In some embodiments of the present invention, an opening I11 is provided on each of the upper and lower through-partitions. The opening I is located at the center of each of the upper and lower through-partitions, allowing the interiors of the upper, reinforced, and lower steel pipe columns to communicate with each other. The openings in the upper and lower through-partitions allow for internal communication between the upper, reinforced, and lower steel pipe columns, facilitating the flow and solidification of concrete during pouring, allowing the concrete inside to form a cohesive whole for better force absorption and transmission, and facilitating subsequent maintenance and inspection.

[0032] In some embodiments of the present invention, the upper diagonal rib is provided with a plurality of openings II 12, which are spaced apart along the length of the upper diagonal rib and extend through opposite sides of the upper diagonal rib. The lower diagonal rib is provided with a plurality of openings III, which are spaced apart along the length of the lower diagonal rib and extend through opposite sides of the lower diagonal rib. The openings in the upper and lower diagonal ribs not only reduce weight but also improve stress concentration. These openings disperse local stress, facilitate uniform load transfer, and reduce the risk of fatigue damage caused by stress concentration. They also enhance the pinning effect between the internal concrete and the diagonal ribs, improving the interaction between the steel pipe and concrete while more effectively transferring the force borne by the diagonal ribs to the concrete, which then transfers it to the overlapping longitudinal bars, thereby enabling continuous force transmission from the diagonal ribs.

[0033] The standardized plate-column node design of the utility model means that most components can be prefabricated in the factory and only need to be assembled on site, which greatly shortens the time on the construction site, reduces the workload such as on-site welding, and improves construction efficiency; the lap longitudinal reinforcement passes through the standard node and is anchored into the upper and lower steel pipe columns, which can effectively solve the problem that the diagonal ribs with open holes in closed spaces cannot be welded and thus cannot continuously transmit force, and the construction is simple; the plate-column node in the utility model is flat and beautiful, and there is no need for additional decoration of the node, saving decoration costs.

[0034] The present invention is not limited to the above-mentioned embodiments. Any structure that is the same as or similar to the above-mentioned embodiments of the present invention is within the protection scope of the present invention.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the present invention that do not depart from the purpose and scope of the technical solution of the present invention should be included in the scope of the claims of the present invention.
