Description

Technical Field

[0001] The invention relates to an earthquake-resistant structure of a building, in particular to an earthquake-resistant masonry filling wall, a construction method of the earthquake-resistant masonry filling wall and a yield restraint supporting structure. Background Art

[0002] In the construction of some large-story and large-span buildings (such as theaters, gymnasiums and other facilities), in order to meet the functional design technical requirements of the buildings and enhance their seismic performance, a buckling restrained support structure with an approximate "eight" shape arrangement is set between the middle of the beam of a set of bay structures and the corners of the columns on both sides below, and brick masonry filling walls are used in the three spaces separated by the buckling restrained support structure.

[0003] Specifically, the buckling restrained 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. Among them, the beam side node plate assembly is anchored at the middle of the bottom side of the upper beam body, and the two corners of the bottom of the beam side node plate of the beam side node plate assembly respectively have damping connection positions of inclined surface structure. The two sets of column side node plate assemblies are correspondingly anchored at the column corners at both ends of the lower beam body, and the column side node plate of each set of column side node plate assemblies has a damping connection position of inclined surface structure. 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 assemblies, and are arranged in an eight-shaped structure. In the inner frame space of the two sets of viscous dampers arranged in the eight-shaped structure, the lower wall is built with bricks. In the outer frame space of the two sets of viscous dampers arranged in the eight-shaped structure, the upper wall is built with bricks. In this way, an earthquake-resistant masonry infill wall is formed in the large bay structure of the building.

[0004] In the above-mentioned seismic masonry infill wall, the bottom of the lower wall is located on the top side of the lower beam body, and a caulking gap is formed between the top of the lower wall and the corresponding viscous damper and filled with a flexible caulking layer. The bottom of each upper wall needs to be located on the bearing structure at the upper side of the corresponding viscous damper, and the bearing structure is directly supported to avoid gravity acting on the corresponding viscous damper, so that a caulking gap is formed between the bearing structure and the corresponding viscous damper and filled with a flexible caulking layer. For example, the Chinese patent document discloses a technology named "A structure for isolating BRB from surrounding partition walls", publication number CN 219794270 U, publication date October 3, 2023; a technology named "Seismic resistant building wall", publication number CN 210105036 U, publication date February 21, 2020; and a technology named "A connection structure of a buckling restrained support and a filling wall", publication number CN218933450 U, publication date April 28, 2023.

[0005] In the technologies of CN 219794270 U and CN 210105036 U, the bearing structure of the upper wall is a channel steel structure, and its two ends are pre-buried between the upper beam and the corresponding column. In the technology of publication number CN218933450 U, the bearing structure of the upper wall is a concrete slab structure, and the internal main reinforcement at both ends is anchored between the upper beam and the corresponding column. It can be seen that the existing seismic masonry infill wall based on the buckling restraint support structure directly anchors the bearing structure of the upper wall between the upper beam and the corresponding column. It is necessary to form the supporting structure of the upper wall before the viscous damper is erected and at the same time as the upper beam and column are cast. When the two sets of viscous dampers are erected, there is already an upper wall bearing structure arranged in an approximate "eight" shape in the masonry infill frame. In addition, based on the narrow matching clearance between the bearing structure of the upper wall and the viscous damper (usually about 30 mm), the technical difficulty of the integrated connection between the viscous damper on the beam side node plate assembly and the corresponding column side node plate assembly is increased, the operating efficiency is reduced, and it is not conducive to reliably ensuring the technical quality of the integrated connection between the viscous damper on the beam side node plate assembly and the corresponding column side node plate assembly, thereby affecting the seismic performance. Summary of the invention

[0006] The technical purpose of the present invention is to provide a seismic masonry infill wall that can effectively support the upper wall and prevent the gravity of the upper wall from acting on the corresponding viscous damper, and can make the bearing structure of the upper wall easy to form after the beams and columns are formed, which is conducive to first erecting the viscous damper and then forming the upper wall bearing structure, as well as a construction method of the seismic masonry infill wall and a buckling restrained support structure.

[0007] The technical purpose of the present invention is achieved by the following technical solution: an earthquake-resistant masonry infill wall, comprising a left column and a right column arranged in left and right positions, and an upper beam and a lower beam arranged in upper and lower positions between the left column and the right column, wherein the upper beam, the lower beam, the left column, and the right column together form a masonry infill frame; In the masonry filling frame, a beam side node plate assembly is anchored at the middle of the bottom side of the upper beam body, a group of column side node plate assemblies is anchored at the corner between the lower beam body and the left column body, another group of column side node plate assemblies is anchored at the corner between the lower beam body and the right column body, and two groups of viscous dampers are connected between the beam side node plate assembly and the two groups of column side node plate assemblies in an eight-shaped arrangement structure; The lower wall is built with bricks in the inner frame space of the two groups of viscous dampers arranged in an eight-shaped pattern; In the outer frame space of the two groups of viscous dampers arranged in an eight-shaped pattern, a concrete slab is formed along the oblique direction of the corresponding viscous damper, and a caulking gap is left between the bottom side of the concrete slab and the corresponding viscous damper; The middle part of each concrete slab is connected to the upper beam body through a second concrete structural column, and both ends of each concrete slab are fixed to the beam side node plate assembly and the corresponding column side node plate assembly by internal main reinforcement; An upper wall is built with bricks in the outer frame space of each concrete slab.

[0008] Furthermore, rear anchor main reinforcements are fixed to the corresponding rib plates of the beam side node plate assembly and the column side node plate assembly respectively by double-sided welding; The two ends of the concrete slab are internally provided with main reinforcements, which overlap and match with the corresponding rear-anchor main reinforcements on the beam side node plate assembly and the column side node plate assembly, and the overlap length is ≥ 50d of the internal main reinforcements. The overlap is fixed by tying with multiple tie bars.

[0009] Furthermore, the second concrete structural column and the corresponding brick masonry end of the upper wall are interlocked in a concave and convex manner.

[0010] Furthermore, in the lower wall, a concrete structural column 1 is arranged with its top located in the middle of the beam side node plate assembly and its bottom located in the middle of the lower beam body; The concrete structural column 1 and the corresponding brick masonry end of the lower wall are interlocked in a concave and convex manner.

[0011] Furthermore, a rear anchor main reinforcement is fixed to the corresponding rib plate in the middle of the beam side node plate assembly by double-sided welding; The top of the inner main reinforcement of the concrete structural column 1 overlaps with the rear anchor main reinforcement at the middle of the beam side node plate assembly, and the overlap length is ≥ 50d of the inner main reinforcement, and the overlap is fixed by a plurality of tie bars; The bottom end of the inner main reinforcement of the concrete structural column 1 is planted in the lower beam body by gluing.

[0012] Furthermore, a caulking gap is respectively left between the lower wall and the two sets of viscous dampers; The caulking joints between the two sets of viscous dampers and the lower wall, and the caulking joints between the two concrete slabs, have a width of 30 to 40 mm respectively; The filling seam has a bulk density of 35 kg / m 3 Extruded polystyrene board.

[0013] In view of the particularity of the buckling restrained support structure, the seismic masonry infill wall connects each concrete slab used to support the upper wall with the upper beam through the middle concrete structural column 2, and connects with the beam side node plate assembly and the corresponding column side node plate assembly through the internal main reinforcement at both ends, so as to clearly support the upper wall and prevent the gravity of the upper wall from acting on the corresponding viscous damper. This forming structure of the concrete slab can meet the requirements of reliable bearing and is basically independent of the forming process of the upper beam and the corresponding column during forming, that is, the concrete slab can be easily formed after the beam and the column are formed, so that it is convenient to first set up the viscous damper and then form the concrete slab, leaving sufficient working space for the setting up of the viscous damper, thereby reducing the technical difficulty of the integral connection between the beam side node plate assembly and the corresponding column side node plate assembly, improving the working efficiency and the technical quality of the integral connection, and improving the seismic performance.

[0014] In addition, the molding structure of the seismic masonry infill wall, through the cooperation of the corresponding concrete structural columns and brick masonry, makes the lower wall and the upper wall respectively form high-quality integrity to improve the seismic performance of the masonry infill. By filling the corresponding caulking joints with extruded polystyrene boards, the lower wall of the masonry infill, the concrete slab and the corresponding viscous damper form a flexible cooperation, thereby achieving a slow seismic isolation effect and improving the seismic performance under the premise of achieving filling.

[0038] In order to ensure the seismic performance of the above-mentioned building, in the above-mentioned masonry filling frame, at the middle part of the bottom side of the upper beam body 3, a beam side node plate assembly 6 of the following structure is anchored; at the corner between the lower beam body 4 and the left column body 1, a group of column side node plate assemblies 5 of the following structure is anchored; at the corner between the lower beam body 4 and the right column body 2, another group of column side node plate assemblies 5 of the following structure is anchored; two groups of viscous dampers 7 are connected between the beam side node plate assembly 6 and the two groups of column side node plate assemblies 5 in an eight-shaped arrangement structure. Based on this, the two groups of viscous dampers 7 divide the above-mentioned masonry filling frame into three relatively independent frame spaces, one space is located between the angles of the two groups of viscous dampers 7 - that is, the inner frame space; one space is located on the outside of the left-side viscous damper 7, that is, the space enclosed by the left-side viscous damper 7 and the left column 1 and the upper beam 3 - the outer frame space; the other space is located on the outside of the right-side viscous damper 7, that is, the space enclosed by the right-side viscous damper 7 and the right column 1 and the upper beam 3 - the outer frame space.

[0039] In the inner frame space of the two groups of viscous dampers 7 arranged in the figure eight, a lower wall 8 is built by bricks. Specifically, in the lower wall 8, a concrete structural column 9 is arranged, the top of which is located in the middle of the beam side node plate assembly 6 and the bottom is located in the middle of the lower beam body 4.

[0040] On the corresponding rib plate in the middle of the beam side node plate assembly 6, namely the beam side node transverse rib plate 6022 described below, rear anchor main bars are fixed by double-sided welding. The top of the inner main bar of the concrete structural column 9 overlaps with the rear anchor main bar in the middle of the beam side node plate assembly 6, and the overlap length is at least 50d of the inner main bar. The overlap is fixed by a plurality of tie bars. The bottom of the inner main bar of the concrete structural column 9 is planted in the lower beam body 4 by drilling and gluing. This method is relatively flexible in determining the forming position while meeting the force requirements, and has high construction efficiency and low cost. The concrete structural column 9 forms a concave-convex interlocking fit with the corresponding brick masonry ends on the left and right sides of the lower wall 8 to improve the integrity of the lower wall 8 in the entire space.

[0041] The lower wall 8 of the above structure has a caulking gap between its top and the two sets of viscous dampers 7. The width of the caulking gap is about 30 mm (it can also be 40 mm or 35 mm, etc., specifically selected within the range of 30 to 40 mm according to design requirements. If the range is too large, it is not conducive to ensuring the stability of the filling, and if it is too small, it will not have a good soft shock-absorbing and isolation effect). The caulking gap is filled with a bulk density of 35 kg / m 3 The extruded polystyrene board forms a filling layer 13 between the lower wall 8 and the corresponding viscous damper 7.

[0042] In each outer frame space of the two groups of viscous dampers 7 arranged in the figure eight, a concrete slab 10 is formed along the oblique direction of the corresponding viscous damper 7, and a caulking gap with a width of about 30 mm (it can also be 40 mm or 35 mm, etc., specifically selected within the range of 30 to 40 mm according to design requirements, if the range is too large, it is not conducive to ensuring the stability of the filling, and if it is too small, it will not have a good soft shock-absorbing and isolation effect); a concrete slab 10 with a bulk density of 35 kg / m is filled in the caulking gap. 3 The extruded polystyrene board forms a filling layer 13 between the concrete slab 10 and the corresponding viscous damper 7.

[0043] The middle part of each concrete slab 10 is connected to the upper beam 3 through a concrete structural column 12 .

[0044] The two ends of each concrete slab 10 are fixed to the beam side node plate assembly 6 and the corresponding column side node plate assembly 5 by the internal main reinforcement 1001. Specifically, the corresponding rib plates of the beam side node plate assembly 6 and the column side node plate assembly 5 (i.e., the beam side node vertical rib plate 6023 of the beam side node plate assembly 6 described below; the column side node plate transverse rib plate 5032 of the column side node plate assembly 5 described below) are respectively fixed with rear anchor main reinforcement by double-sided welding. Figure 2 The rear anchor main reinforcement 504 on the column side node plate assembly 5 is shown; the main reinforcement 1001 is provided at both ends of the concrete slab 10, and is overlapped with the corresponding rear anchor main reinforcement on the beam side node plate assembly 6 and the column side node plate assembly 5 (such as Figure 2 The inner main reinforcement 1001 of the concrete slab 10 shown forms an overlap with the rear anchor main reinforcement 504 on the column side node plate assembly 5), and the overlap length is at least 50d of the inner main reinforcement 1001 of the concrete slab 10, and the overlap is fixed by a plurality of tie bars.

[0045] The forming structure of the concrete slab 10 is supported by the beam side node plate assembly 6, the column side node plate assembly 5 and the concrete structural column 2 12, and is basically independent of the corresponding column and the upper beam 3, so that the concrete slab 10 does not need to be considered when the corresponding column and the upper beam 3 are formed, and it is left to be formed independently later. In this way, the viscous damper 7 can be flexibly installed first, and then the concrete slab 10 can be independently formed, so as to ensure the feasibility and high quality of the installation of the viscous damper 7.

[0046] An upper wall 11 is built with bricks in the outer frame space of each concrete slab 10. Concrete structural columns 12, which play a connecting role between the corresponding concrete slab 10 and the upper beam 3, are interlocked with the corresponding brick masonry ends on the left and right sides of the upper wall 11 to improve the integrity of the upper wall 11 in the entire space.

[0047] See also Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, the buckling restrained bracing structure used in the above-mentioned seismic masonry infill wall includes a group of beam side node plate assemblies 6, two groups of column side node plate assemblies 5 and two groups of viscous dampers 7.

[0049] Specifically, the upper beam anchoring assembly 601 has a beam side flange plate 6011 of a rectangular steel plate structure. At the top side of the beam side flange plate 6011, a plurality of beam side embedded T-shaped plates 6012 are arranged in a matrix in two rows and multiple columns based on the length direction, and these beam side embedded T-shaped plates 6012 are distributed as carriers; each beam side embedded T-shaped plate 6012 is a T-shaped steel plate structure; adjacent beam side embedded T-shaped plates 6012 are arranged at intervals, and the T-shaped end of each beam side embedded T-shaped plate 6012 is formed along the width direction of the beam side flange plate 6011, and there is a beam side stirrup groove 6013 of a U-shaped structure between two adjacent beam side embedded T-shaped plates 6012. These beam side embedded T-shaped plates 6012 are installed in the internal main reinforcement structure of the upper beam body 3, and each internal main reinforcement of the upper beam body 3 passes through the front, middle and rear spaces of these beam side embedded T-shaped plates 6012 along the length direction of the beam side flange plate 6011, and each tie bar of the upper beam body 3 passes through the corresponding beam side stirrup groove 6013 between adjacent beam side embedded T-shaped plates 6012. In this way, the upper beam anchoring assembly 601 is anchored at the middle of the bottom side of the upper beam body 3.

[0050] The beam side node plate 602 is assembled and fixed on the upper beam anchoring assembly 601 by full penetration welding, and is exposed on the bottom side of the upper beam body 3 and extends downward. The beam side node plate 602 has damping connection positions at the bottom two corners respectively. It can be seen that the beam side flange plate 6011 of the upper beam anchoring assembly 601 is a transition structure for anchoring the beam side node plate 602 on the upper beam body 3. The beam side node plate 602 has a beam side node web plate 6021, a beam side node transverse rib plate 6022, two beam side node vertical rib plates 6023, two reinforcing rib plates 6024 and four beam side node connection rib plates 6025. The beam side node web plate 6021 has damping connection positions formed with inclined surface structures at the bottom two corners respectively. The beam side node transverse rib plate 6022 is formed at the bottom edge of the beam side node web plate 6021 in a T-shaped structure. Two beam side node vertical ribs 6023 are formed in a T-shaped structure at both ends of the beam side node web 6021 in the length direction. Two reinforcing ribs 6024 are formed in a T-shaped structure at the front and rear sides of the beam side node web 6021, and the bottom ends form a T-shaped fit with the beam side node transverse ribs 6022, and the top ends form a T-shaped fit with the beam side flange plate 6011; each reinforcing rib 6024 is arranged vertically at the center of the beam side node web 6021 in the length direction. The four beam side node connection ribs 6025 are divided into two groups; the two beam side node connection ribs 6025 in each group are formed in a T-shaped structure at the front and rear sides of the beam side node web 6021 corresponding to the damping connection position, and form a cross-shaped matching structure with the beam side node web 6021.

[0051] The column side node plate assemblies 5 are divided into two independent groups, and the structures of the two groups of column side node plate assemblies 5 are basically the same with left-right symmetrical structures. The two groups of column side node plate assemblies 5 are arranged at the column corners at both ends of the lower beam body 4 below the upper beam body 3.

[0052] The structure of one group of column side node plate assemblies 5 is described in detail below, and the other group will not be described in detail.

Adjacent column-side vertical embedded T-shaped plates 5012 are arranged with spacing therebetween, and the T-shaped end of each column-side vertical embedded T-shaped plate 5012 is formed along the width direction of the column-side transverse flange plate 5011. A column-side vertical stirrup groove 5013 with a U-shaped structure is provided between two adjacent column-side vertical embedded T-shaped plates 5012. These column-side vertical pre-embedded T-shaped plates 5012 are installed in the inner main reinforcement structure of the lower beam body 4, and each inner main reinforcement of the lower beam body 4 passes through the front, middle and rear spaces of these column-side vertical pre-embedded T-shaped plates 5012 along the length direction of the column-side transverse flange plate 5011, and each tie bar of the lower beam body 4 passes through the corresponding column-side vertical stirrup grooves 5013 between adjacent column-side vertical pre-embedded T-shaped plates 5012. In this way, the lower beam anchoring assembly 501 is anchored at the top side of one end of the lower beam body 4 in the left-right direction.

[0055] The column anchoring assembly 502 has a column side vertical flange plate 5021 of a rectangular steel plate structure.

The T-shaped end of each column side transverse embedded T-shaped plate 5022 is formed along the width direction of the column side vertical flange plate 5021. There is a column side transverse stirrup groove 5023 with a U-shaped structure between two adjacent column side transverse embedded T-shaped plates 5022. These column-side transverse pre-embedded T-shaped plates 5022 are installed in the internal main reinforcement structure of the corresponding column, and the internal main reinforcement of the corresponding column passes through the front, middle and rear spaces of these column-side transverse pre-embedded T-shaped plates 5022 along the height direction of the column-side vertical flange plate 5021, and the tie bars of the corresponding column pass through the corresponding column-side transverse stirrup grooves 5023 between adjacent column-side transverse pre-embedded T-shaped plates 5022. In this way, the column anchoring assembly 502 is anchored at the bottom of the corresponding column near the lower beam body 4, and the column anchoring assembly 502 and the lower beam anchoring assembly 501 form an L-shaped matching relationship at the column corner at the end of the lower beam body 4.

[0056] The column side node plate 503 is assembled and fixed at the L-shaped fitting between the column anchor assembly 502 and the lower beam anchor assembly 501 by full penetration welding, and is exposed at the column foot between the lower beam body 3 and the corresponding column, and extends inwardly and upwardly at the column foot. The inwardly and upwardly extending vertex of the column side node plate 503 has a damping connection position.

At the top outer corner of the column side node web plate 5031, there is a damping connection position formed with an inclined surface structure. The column side node transverse rib plate 5032 is formed at the top edge of the column side node web plate 5031 in the height direction with a T-shaped structure, and is spaced in coordination with the column side transverse flange plate 5011. The column side node vertical rib plate 5033 is formed at the end of the column side node web plate 5031 in the length direction with a T-shaped structure, and is spaced in coordination with the column side vertical flange plate 5021. The two column side node connection rib plates 5034 are respectively formed at the front and rear sides of the damping connection position of the column side node web plate 5031 with a T-shaped structure, and form a cross-shaped matching structure with the column side node web plate 5031.
