Description
Technical Field
The invention relates to a strip-shaped reinforced node for connecting an H-shaped steel beam with the short edge of a wide concrete-filled steel tubular column, which can be widely applied to rigid connection of the H-shaped steel beam with the short edge of the wide concrete-filled steel tubular column in a multi-story high-rise steel structure.
Background
Among many high-rise steel construction, the girder steel is mostly H shaped steel roof beam, and the steel column is mostly the wide steel core concrete column of rectangle. The rigid connection of steel beams and steel columns is the most basic measure for providing the overall rigidity and the seismic performance of the structure. The existing common rigid joint is that a transverse partition plate is arranged at the position of a steel column corresponding to a beam flange, and the internal force of the beam flange is transmitted to the steel column through the partition plate, so that the rigid joint is formed. The partition plate is provided with an inner partition plate and a through diaphragm plate which are respectively corresponding to two components of a box-type column and a cold-roll forming high-frequency welding rectangular steel pipe column.
In order to conveniently pour concrete in the steel pipe column, grouting holes and air holes need to be formed in the partition plate, and the diameter of each grouting hole is not smaller than 150mm. In addition, the weakening of the diaphragm by the grouting holes cannot be too large for the force transmission requirement in the node area, so that the section width of the steel column cannot be too small, and is generally not less than 350-400 mm. In steel structure houses, the convex column phenomenon can occur at four corners of each functional room of the house due to the overlarge section of the steel column, and the use function of indoor buildings is affected, so that the structural members are hidden in the thickness of the wall body as much as possible, and the section width of the steel members adopted in the houses is required to be controlled between 150mm and 300mm optimally.
At present, building industrialization and housing industrialization are being vigorously popularized in China, and a steel structure is a good assembly type building product and has extremely superior seismic resistance. How to apply the steel structure to a housing system, fully exert the characteristics of steel structure industrialization, and meet the functional requirements of housing buildings is a very important and urgent task. Therefore, in order to solve the problem of indoor convex columns, a form of adopting wide steel tube concrete columns is provided, the size of the short side of each steel box column is made to be as small as possible, the short side is equal to the thickness of a concrete shear wall, the size of the long side of each steel box column is made to be as large as possible, and the wide steel tube concrete columns are formed so as to meet the requirements of houses on steel structure systems. However, the size of the short side of the section of the wide concrete filled steel tubular column is small, so that a diaphragm plate cannot be arranged in a node area for ensuring smooth pouring of the internal concrete, and the connection with a steel beam cannot adopt the form of the diaphragm plate.
Based on the technical background, the current engineering practice has the contradiction that the partition plate connecting node requires that the section of a steel column cannot be too small, and the construction function requires that the section of the steel column cannot be too large.
Disclosure of Invention
In order to overcome the contradiction that the prior clapboard type beam column rigid connection node and a steel structure house need a smaller steel column section and match the development of a wide steel tube concrete column house structure system, the invention provides the strip-shaped reinforced node for connecting the H-shaped steel beam and the short edge of the wide steel tube concrete column, which can be widely applied to the rigid connection of the H-shaped steel beam and the wide steel tube concrete column in a multi-high-rise steel structure, has the advantages of simple node form, convenient and quick processing and clear force transmission path, can meet the force transmission requirement of the beam column rigid connection node, and can not form the obstruction to the pouring of the concrete in the tube.
The technical scheme adopted by the invention is as follows:
the invention comprises a wide steel tube concrete column and an H-shaped steel beam, wherein the flange of the H-shaped steel beam is rigidly connected to the side surface of the wide steel tube concrete column through a strip-shaped reinforcing plate, and the web of the H-shaped steel beam is rigidly connected to the side surface of the wide steel tube concrete column through the combination of a connecting plate and a high-strength bolt.
The web plate of the H-shaped steel beam is connected with one end of a connecting plate through a high-strength bolt, and the other end of the connecting plate is welded to the side face of the short side of the wide steel tube concrete column.
The end face of the flange of the H-shaped steel beam is welded to a strip-shaped reinforcing plate, and the strip-shaped reinforcing plate is tightly adhered and fixed to the side face of the short edge or the long edge of the wide steel tube concrete column.
When the H-shaped steel beam is rigidly connected to only the short side or the long side of the wide steel tube concrete column, the two horizontal ends of the strip-shaped reinforcing plate are connected with the flitch, and the flitch is tightly fixed to the side face of the long side or the short side of the wide steel tube concrete column.
The thickness of the strip-shaped reinforcing plate is larger than that of the flitch plate. In the concrete implementation, the thickness of the banded reinforcing plate needs to meet the requirement of force transfer rigidity, and the thickness of the banded reinforcing plate needs to meet the requirement that the banded reinforcing plate cannot generate plastic deformation, so that the internal force of the flange of the steel beam is transferred to the flitch plates on two sides. The thickness of the strip-shaped reinforcing plate is calculated and determined according to the width of the steel beam flange and the size of the short side of the wide steel pipe concrete column and can be 20-35mm, and the thickness of the flitch can be determined according to the size of the section of the steel beam flange and can be 8-16mm.
If the wide steel pipe concrete column is located in the middle of the building plane, the side face of the wide steel pipe concrete column is connected with steel beams in multiple directions in a rigid connection mode. When the short edge and the long edge of the wide steel tube concrete column are both rigidly connected with H-shaped steel beams, the H-shaped steel beams are connected to the side face of the short edge or the long edge of the wide steel tube concrete column through respective strip-shaped reinforcing plates, and two strip-shaped reinforcing plates arranged on the adjacent side faces of the wide steel tube concrete column are welded; an inserting plate penetrating through the wide steel pipe concrete column is connected between the two strip-shaped reinforcing plates arranged on the opposite side surfaces of the wide steel pipe concrete column, and two ends of the inserting plate penetrate through the wide steel pipe concrete column and are respectively welded with the two strip-shaped reinforcing plates; the wide steel pipe concrete column is provided with a through groove for the insertion plate to penetrate through, and the insertion plate is welded with the edge of the through groove.
Namely, the following steps are formed: the terminal surface welding on H shaped steel beam flange first banded reinforcing plate, first banded reinforcing plate pastes tightly to be fixed in wide steel core concrete column minor face place side, second, third banded reinforcing plate one end are respectively reconnected at first banded reinforcing plate horizontally both ends, second, third banded reinforcing plate paste tightly to be fixed in wide steel core concrete column long limit place side. The inserting plate penetrates through the wide steel pipe concrete column and then is welded to the other ends of the second and third strip-shaped reinforcing plates.
Preferably, when the earthquake-resistant requirement of the area where the structure is located is high, or because the structure height is larger, the earthquake-resistant grade of the structure has a stricter requirement on the strong node and weak member. In this case, the cover plates are arranged on both the upper flange and the lower flange of the H-shaped steel beam, the cover plates are tightly attached to and welded on the flange surfaces of the H-shaped steel beam, and the end parts of the cover plates are welded on the strip-shaped reinforcing plates.
The strip-shaped reinforcing plate and the flitch plate are welded through a welding seam, and the edges of the strip-shaped reinforcing plate and the flitch plate are welded with the surface of the side face of the short edge of the wide concrete-filled steel tubular column through the welding seam.
The edges of the strip-shaped reinforcing plates and the surface of the side face of the short side of the wide steel tube concrete column are welded through welding seams.
The wide steel pipe concrete column is formed by pouring concrete in a rectangular steel pipe, and the ratio of the long edge to the short edge of the rectangular steel pipe is 1-4.
The technical principle of the invention is as follows:
1. the bending moment of girder steel tip shows the pressure axle power that draws for the upper and lower edge of a wing in the node region, and this axle power transmits the banded reinforcing plate through the welding seam between edge of a wing and the banded reinforcing plate earlier on, and the rigidity of banded reinforcing plate is very big, can directly transmit the flitch of the long limit both sides of wide steel core concrete column with the axle power through the banded reinforcing plate, and final axle power transmits the wide steel core concrete column for through the flitch, and node power transmission route is very clear and definite.
2. The end part of the wide steel pipe concrete column is simultaneously connected with the steel beams in multiple directions in a rigid mode, the flitch outside the long edge of the column is changed into a strip-shaped reinforcing plate, and meanwhile the inserting plate is additionally arranged, so that the effect of reinforcing a node connection area can be achieved. Particularly, in a joint connecting area of a column end and a steel beam, the inserting plate and wall plates on three sides of the column form a box-shaped closed area, so that the integrity of the joint area of the column end is improved, the column joint area and the joint area have good rigidity and strength, and the complex stress state of the column end is effectively improved; meanwhile, the strip-shaped reinforcing plates on the three surfaces of the column end play a continuous strip-shaped reinforcing role in the box-shaped area, so that the steel beam flange tension and compression axial force in multiple directions can be reliably transmitted to the wide steel tube concrete column.
3. The upper flange and the lower flange of the steel beam are provided with the cover plates, so that the plastic hinge can be ensured to be arranged on the steel beam far away from the node area under the action of an earthquake, the node area cannot be damaged firstly, and the earthquake-resistant ductility of the node is improved.
4. The shear force at the end of the steel beam is transferred to the connecting plate through the high-strength bolt between the steel beam web plate and the connecting plate and then transferred to the column through the connecting plate.
The beneficial effects of the invention are:
1. the node structure is simple to process, and compared with the existing rectangular wide steel pipe concrete column-steel beam rigid connection node, the node does not need to be provided with an inner partition plate and electroslag welding, so that the processing and manufacturing difficulty is reduced.
2. The invention solves the problem of rigid connection between the end part of the wide steel pipe concrete column and steel beams in multiple directions, and mainly provides a construction method for rigid connection between the wide steel pipe concrete column and the steel beams in the strong axis direction and the weak axis direction.
3. The node form of the invention is subjected to experimental research, and the experimental result shows that the node structural form provided by the invention can ensure the rigidity and strength of the node and the node domain, plastic hinges are observed on the steel beam in the test process, the ductility coefficient of the node reaches more than 4, and the design target of strong node and weak members can be realized.
4. Because no partition plate is arranged in the wide steel pipe concrete column, the concrete is easy to pour and is not influenced, and the concrete in the pipe can be ensured to have good pouring quality.
The invention can be widely applied to the connection node of the wide steel pipe concrete column and the steel beam with smaller section short edge size in residential buildings such as steel structure houses, apartments and the like.
Compared with other existing node structures, the invention has the advantages of convenience, building adaptability and material saving.
The material saving is shown as follows: in the prior art, complicated parts such as brackets and the like are usually needed for other nodes, 7-9 parts are needed for assembly and connection between a single steel beam and a column, and two strip-shaped reinforcing plates corresponding to upper and lower flanges and three parts of a connecting plate are needed for assembly and connection between the single steel beam and the column.
The convenience is realized in that: because the standardization of structure, the minor face size of all wide steel core concrete columns is the same, and the height of girder steel, edge of a wing width are the same, can standardize the node like this, and the specification of banded reinforcing plate and both sides flitch can merge into effectual two to three kinds, brings very big facility to the standardization of node. The factory can produce the node parts in batches, only standardized assembly is needed at each node, convenience is brought to the manufacturing of the component, and meanwhile, the quality of the product is improved.
The adaptability is realized as follows: compared with the prior plate-attaching type node and the prior plate-inserting type node, the bracket is not required to be arranged due to the arrangement of the strip-shaped reinforcing plate, the steel beam is directly welded with the node of the steel column, the node is simple in structure, does not protrude outwards relatively to a member, and is high in decoration coating adaptability to the steel beam and the steel column.
