Description

Technical Field

[0001] The utility model relates to an anti-seismic support structure between a beam body and a column body of a building, in particular to a buckling restraint support structure. Background Art

[0002] In the construction of some buildings with large floor height and large span (such as theaters, gymnasiums and other facilities), in order to meet the functional design technical requirements of the building and enhance the seismic performance, a buckling restraint support structure with an approximate "eight" arrangement will be set between the middle of a set of bay structure beams and the corners of the columns on both sides below. Specifically, the buckling restraint support structure includes a set of beam side node plate assemblies, two sets of column side node plate assemblies and two sets of viscous dampers, wherein the beam side node plate assembly is anchored at the bottom side of the beam body, and the two corners of the bottom of the beam side node plate of the beam side node plate assembly have damping connection positions respectively; the two sets of column side node plate assemblies are correspondingly anchored at the corners of the columns on both sides below the beam body where the beam side node plate assembly is located, and each set of column side node plate assemblies has a damping connection position on the column side node plate; the two sets of viscous dampers are correspondingly connected between the two sets of column side node plate assemblies and the beam side node plate assembly, and are arranged in an eight-shaped structure. This buckling-restrained brace structure reduces or even avoids damage to the main body of the building during an earthquake through its own stiffness and hysteretic energy dissipation generated before the main structure of the building yields. It is relatively widely used in the seismic design of public buildings.

[0003] It can be seen from the above buckling restrained support structure that when the beam body of the building is formed, the beam side node plate assembly is anchored inside the beam body as the reinforced concrete structure of the beam body is formed; when the column body of the building is formed, the column side node plate assembly is anchored inside the column body as the reinforced concrete structure of the column is formed. Therefore, the beam side node plate assembly and the column side node plate assembly each have an embedded part structure for anchoring and forming.

[0004] The traditional embedded parts of the buckling restrained support structure are L-shaped steel bar structures (i.e., anchor bar structures) arranged on the corresponding flange plates. The L-shaped steel bars on the corresponding flange plates are densely arranged, and the force is not clear, so they are only suitable for working conditions with smaller BRB tonnage. In recent years, in order to make the embedded parts of the buckling restrained support structure bear force clearly and bear larger BRB tonnage, the industry has designed various closed H-type structure embedded parts, such as the Chinese patent document named "A connection node of reinforced concrete frame-buckling restrained support structure", announcement number CN 218264315 U, publication date January 10, 2023, named "Connection structure and method of embedded positioning plate of buckling restrained support column and column steel bar", publication number CN 115434438 A, publication date December 6, 2022, and named "A buckling restrained support node plate embedded part", announcement number CN215330525 U, publication date December 28, 2021 and other technologies.

[0005] The embedded parts of the closed H-shaped structure have the technical characteristics of clear force and can carry a large BRB tonnage due to its integrated structure. However, it is precisely because of its integrated structure that there is a direct position interference with the steel skeleton structure of the building beam or column, which increases the difficulty of construction technology.

[0006] Specifically, if the closed H-shaped structural embedded parts are first installed in the angle bars and main bars arrangement structure of the steel skeleton, the stirrups of the steel skeleton need to be installed and tied in the gaps of the embedded parts. Due to the rigid structural characteristics of the stirrups, the difficulty of installing and tying them in the gaps of the embedded parts increases, which directly affects the construction efficiency. If the stirrups of the steel skeleton are first tied to the angle bars and main bars, the channel for the installation of the closed H-shaped structural embedded parts in the angle bars and main bars arrangement structure is directly blocked due to the dense binding of the steel bars on the angle bars and main bars. At this time, if the stirrups are disconnected first and forcibly installed and then welded, it will inevitably increase the difficulty of construction technology and reduce construction efficiency. It will also affect the bearing capacity of the beams or columns of the building, and the feasibility is low. Utility Model Content

[0042] It should be noted that the drawings of the present invention are schematic, and unnecessary details have been simplified to clarify the technical purpose of the present invention, so as to avoid blurring the technical solution of the present invention in the prior art. In addition, the expressions "approximately" and "substantially" in the following text regarding quantity or matching relationship mean that reasonable assembly errors and processing errors in the industry are allowed to exist, and do not literally express absolute quantity or matching relationship.

[0043] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the buckling restrained support structure of the utility model comprises a set of beam side node plate assemblies 1, two sets of column side node plate assemblies 2 and two sets of viscous dampers 3. The two sets of column side node plate assemblies 2 have the same structure, and only one set is taken as an example to explain in detail its forming structure. The two sets of viscous dampers 3 have the same structure, and only one set is taken as an example to explain in detail its connection structure with the beam side node plate assembly 1 and the column side node plate assembly 2.

[0044] The beam side node plate assembly 1 comprises a beam side flange plate 14 , a beam side node plate and a plurality of beam side embedded T-shaped plates 11 .

[0045] Specifically, the beam side flange plate 14 is a rectangular steel plate structure, which is used to transitionally connect the beam side node plate and the beam side embedded T-shaped plate 11 .

[0046] Each beam side embedded T-shaped plate 11 is a T-shaped steel plate structure, and its T-shaped end has an edge plate that forms a T-shaped vertical fit with the web. Several beam side embedded T-shaped plates 11 are arranged evenly and evenly at the top side of the beam side flange plate 14 along the length direction of the beam side flange plate 14, and the T-shaped end (i.e., edge plate, the same below) of each beam side embedded T-shaped plate 11 is formed along the width direction of the beam side flange plate 14. Of course, the width of the T-shaped end of the beam side embedded T-shaped plate 11 is smaller than the width of the beam side flange plate 14. Between two adjacent beam side embedded T-shaped plates 11, a beam side stirrup groove 12 of a U-shaped structure is formed at the top side of the beam side flange plate 14, and the width of the beam side stirrup groove 12 is smaller than the width of the beam side embedded T-shaped plate 11, which is about 1 / 3 (or 1 / 2) of the width of the beam side embedded T-shaped plate 11.

[0047] These beam side embedded T-shaped plates 11 at the top side of the beam side flange plate 14 are embedded in the steel structure of the building beam body during the construction of the building beam body. In order to further improve the embedded firmness in the building beam body, at the top side of the beam side flange plate 14, corresponding to each beam side embedded T-shaped plate 11, one (or more) beam side anchor rods 13 are arranged at intervals on the front and rear sides of each beam side embedded T-shaped plate 11; the arrangement position of the beam side anchor rods 13 is staggered from the beam side stirrup grooves 12. During the construction of the building beam body, these beam side anchor rods 13 are embedded in the steel structure of the building beam body.

[0048] The beam side node plate is protruded at the bottom side of the above-mentioned beam side flange plate 14. When the beam side flange plate 14 is embedded in the steel structure of the building beam body through the beam side embedded T-shaped plate 11 and the beam side anchor rod 13 of the above-mentioned structure, the beam side flange plate 14 is located below the steel structure of the beam body, and the beam side node plate is protruded below the steel structure of the beam body.

[0049] The beam side node plate comprises a beam side node web plate 16 , two beam side node vertical rib plates 17 , one beam side node transverse rib plate 18 , two reinforcing rib plates 15 and four beam side node connecting rib plates 19 .

[0050] More specifically, the beam side node web 16 is a steel plate structure. The top edge of the beam side node web 16 is welded and formed at the center of the bottom surface of the beam side flange plate 14 along the length direction of the beam side flange plate 14, and is convex downward. At the bottom two corners of the beam side node web 16, damping connection positions are formed in an inclined structure.

[0051] The vertical ribs 17 at the beam side nodes are steel plate structures. The width of the vertical ribs 17 at the beam side nodes is greater than the thickness of the web 16 at the beam side nodes, and the height of the vertical ribs 17 at the beam side nodes is basically matched with the vertical edges of the web 16 at the ends of the length direction. Two vertical ribs 17 at the beam side nodes are welded in a T-shaped structure at both ends of the length direction of the web 16 at the beam side nodes. The top of each vertical rib 17 at the beam side nodes is welded to the above-mentioned beam side flange plate 14, and the two form a T-shaped fit. The bottom of each vertical rib 17 at the beam side nodes extends to the corresponding damping connection position of the web 16 at the beam side nodes.

[0052] The transverse ribs 18 of the beam side nodes are steel plate structures, the width of the transverse ribs 18 of the beam side nodes is greater than the thickness of the webs 16 of the beam side nodes, and the length of the transverse ribs 18 of the beam side nodes is substantially matched with the horizontal vertical edge of the bottom edge of the webs 16 of the beam side nodes in the length direction. The transverse ribs 18 of the beam side nodes are welded and formed at the bottom edge of the webs 16 of the beam side nodes in a T-shaped structure, and the two ends of the transverse ribs 18 of the beam side nodes extend to the corresponding damping connection positions of the webs 16 of the beam side nodes, respectively.

[0053] The stiffener plate 15 is a steel plate structure, the width of the stiffener plate 15 is substantially matched to the width of the beam side node transverse rib plate 18 protruding from the bottom edge of the beam side node web plate 16, and the height of the stiffener plate 15 is matched to the height of the beam side node web plate 16. Corresponding to the center position of the beam side node web plate 16 in the length direction, the stiffener plate 15 is vertically welded and arranged at the center of the length direction of the corresponding side wall surface of the beam side node web plate 16, that is, two stiffener plates 15 are respectively welded and formed in a T-shaped structure at the front and rear sides of the beam side node web plate 16, the bottom end of each stiffener plate 15 is welded with the beam side node transverse rib plate 18 on the side thereof to form a T-shaped matching structure, and the top end of each stiffener plate 15 is welded with the beam side flange plate 14 on the side thereof to form a T-shaped matching structure.

[0054] The beam side node connection ribs 19 are steel plate structures, and the width of the beam side node connection ribs 19 basically matches the width of the reinforcing ribs 15, or basically matches the width of the beam side node transverse ribs 18 / beam side node vertical ribs 17 protruding from one side of the beam side node web 16. The four beam side node connection ribs 19 are divided into two groups corresponding to the damping connection positions at the two corners of the bottom of the beam side node web 16. The two beam side node connection ribs 19 in each group are respectively welded in a T-shaped structure at the front and rear sides of the corresponding damping connection position of the beam side node web 16, forming a cross-shaped matching structure with the beam side node web 16 at the corresponding damping connection position.

[0055] The column side node plate assembly 2 comprises a column side vertical flange plate 24 , a column side transverse flange plate 28 , a column side node plate, a plurality of column side transverse embedded T-shaped plates 21 , and a plurality of column side vertical embedded T-shaped plates 25 .

[0056] Specifically, the column side vertical flange plate 24 is a rectangular steel plate structure, which is used to transitionally connect the column side node plate and the column side transverse embedded T-shaped plate 21. The column side transverse flange plate 28 is a rectangular steel plate structure, which is used to transitionally connect the column side node plate and the column side vertical embedded T-shaped plate 25. Since the column side node plate assembly 2 is anchored at the corner of the building column, the column side vertical flange plate 24 and the column side transverse flange plate 28 of the column side node plate assembly 2 are welded together in an L-shaped structure to form an angle matching structure.

[0057] Each column side transverse embedded T-shaped plate 21 is a T-shaped steel plate structure, and its T-shaped end has an edge plate that forms a T-shaped vertical fit with the web. Several column side transverse embedded T-shaped plates 21 are arranged evenly and evenly at the outer side of the column side vertical flange plate 24 along the height direction of the column side vertical flange plate 24. The T-shaped end of each column side transverse embedded T-shaped plate 21 is formed along the width direction of the column side vertical flange plate 24. Of course, the width of the T-shaped end of the column side transverse embedded T-shaped plate 21 is smaller than the width of the column side vertical flange plate 24. Between two adjacent column side transverse embedded T-shaped plates 21, a column side transverse stirrup groove 22 of a U-shaped structure is formed on the outer side of the column side vertical flange plate 24. The width of the column side transverse stirrup groove 22 is smaller than the width of the column side transverse embedded T-shaped plate 21, which is about 1 / 3 (or 1 / 2) of the width of the column side transverse embedded T-shaped plate 21.

[0058] These column-side transverse embedded T-shaped plates 21 on the outside of the column-side vertical flange plates 24 are embedded in the steel structure of the building column during the construction of the building column. In order to further improve the embedding firmness in the building column, on the outside of the above-mentioned column-side vertical flange plates 24, corresponding to each column-side transverse embedded T-shaped plate 21, one (or more) column-side transverse anchor rods 23 are arranged at intervals on the front and rear sides of each column-side transverse embedded T-shaped plate 21; the arrangement positions of the column-side transverse anchor rods 23 are staggered from the column-side transverse stirrup grooves 22. During the construction of the building column, these column-side transverse anchor rods 23 are embedded in the steel structure of the building column.

[0059] Each column side vertical embedded T-shaped plate 25 is a T-shaped steel plate structure, and its T-shaped end has an edge plate that forms a T-shaped vertical fit with the web. Several column side vertical embedded T-shaped plates 25 are arranged at substantially equal intervals along the length direction of the column side transverse flange plate 28 at the bottom side of the column side transverse flange plate 28. The T-shaped end of each column side vertical embedded T-shaped plate 25 is formed along the width direction of the column side transverse flange plate 28. Of course, the width of the T-shaped end of the column side vertical embedded T-shaped plate 25 is smaller than the width of the column side transverse flange plate 28. Between two adjacent column side vertical embedded T-shaped plates 25, a column side vertical stirrup groove 26 of a U-shaped structure is formed at the bottom side of the column side transverse flange plate 28. The width of the column side vertical stirrup groove 26 is smaller than the width of the column side vertical embedded T-shaped plate 25, and is approximately 1 / 3 (or 1 / 2) of the width of the column side vertical embedded T-shaped plate 25.

[0060] These column side vertical embedded T-shaped plates 25 at the bottom side of the column side transverse flange plate 28 are embedded in the steel structure of the building column during the construction of the building column. In order to further improve the embedding firmness in the building column, at the bottom side of the above-mentioned column side transverse flange plate 28, corresponding to each column side vertical embedded T-shaped plate 25, one (or more) column side vertical anchor rods 27 are arranged at intervals on the front and rear sides of each column side vertical embedded T-shaped plate 25; the arrangement positions of the column side vertical anchor rods 27 are staggered from the column side vertical stirrup grooves 26. During the construction of the building column, these column side vertical anchor rods 27 are embedded in the steel structure of the building column.

[0061] The column side node plate is protruded and formed at the corner between the above-mentioned column side vertical flange plate 24 and the column side transverse flange plate 28, that is, the column side node plate is welded between the inner side of the above-mentioned column side vertical flange plate 24 and the top side of the above-mentioned column side transverse flange plate 28. When the column side vertical flange plate 24 is embedded in the steel structure of the building column through the column side transverse embedded T-shaped plate 21 and the column side transverse anchor rod 23 of the above-mentioned structure, the column side vertical flange plate 24 is located beside the steel structure of the column; and when the column side transverse flange plate 28 is embedded in the steel structure of the building column through the column side vertical embedded T-shaped plate 25 and the column side vertical anchor rod 27 of the above-mentioned structure, the column side transverse flange plate 28 is located above the steel structure of the column, so that the column side node plate is protruded and formed at the corner of the steel structure of the column.

[0062] The column side node plate comprises a beam side node web plate 210 , a column side node vertical rib plate 212 , a column side node transverse rib plate 211 , and two column side node connecting rib plates 29 .

[0063] More specifically, the column side node web 210 is a steel plate structure. One side vertical edge of the column side node web 210 is welded and formed at the center of the vertical surface of the column side vertical flange plate 24 along the height direction of the column side vertical flange plate 24, and is convex to one side. The bottom edge of the column side node web 210 is welded and formed at the center of the top surface of the column side horizontal flange plate 28 along the length direction of the column side horizontal flange plate 28, and is convex upward. At the outer corner of the column side node web 210 (i.e., the corner away from the column side vertical flange plate 24 and the column side horizontal flange plate 28), a damping connection position is formed with an inclined structure.

[0064] The column side node vertical rib plate 212 is a steel plate structure, the width of which is greater than the thickness of the column side node web plate 210, and the height of which is substantially matched to the end vertical edge of the column side node web plate 210 at the damping connection position. The column side node vertical rib plate 212 is welded and formed at the end of the column side node web plate 210 in the length direction in a T-shaped structure, and is spaced in a manner to match the column side vertical flange plate 24, and the bottom end forms a T-shaped welding match with the column side transverse flange plate 28. The top end of the column side node vertical rib plate 212 extends to the damping connection position.

[0065] The column side node transverse rib plate 211 is a steel plate structure, the width of the column side node transverse rib plate 211 is greater than the thickness of the column side node web plate 210, and the length of the column side node transverse rib plate 211 is substantially matched with the horizontal vertical side of the top edge of the column side node web plate 210 in the length direction. The column side node transverse rib plate 211 is welded and formed at the top edge of the column side node web plate 210 in a T-shaped structure, and is spaced in conjunction with the column side transverse flange plate 28, one end of which is welded in conjunction with the column side vertical flange plate 24, and the other end extends to the damping connection position.

[0066] The column side node connection ribs 29 are steel plate structures, and the width of the column side node connection ribs 29 is substantially matched with the width of the column side node transverse ribs 211 / column side node vertical ribs 212 protruding from one side of the column side node web 210. Two column side node connection ribs 29 are respectively welded in a T-shaped structure at the front and rear sides of the damping connection position of the column side node web 210, forming a cross-shaped matching structure with the column side node web 210 at the damping connection position.

[0067] The beam side node plate assembly 1 of the above structure is anchored at the bottom side of the building beam body, and the two corners at the bottom of the beam side node plate of the beam side node plate assembly 1 respectively form damping connection positions below the beam body.

[0068] The two groups of column side node plate assemblies 2 of the above structure are anchored correspondingly at the column corners on both sides below the beam body where the beam side node plate assembly 1 is located. A damping connection position is formed on the column side node plate of each group of column side node plate assemblies 2, forming an oblique one-to-one corresponding matching relationship with the corresponding side damping connection position on the beam side node plate assembly 1.
