Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of recoverable structure, and particularly provides a full dry energy dissipation connecting assembly type shear wall system with recoverable function and a construction method thereof. BACKGROUND

[0002] In order to realize the damage control and post-earthquake repair of buildings, recoverable structures (including shear walls with replaceable components) are proposed and further researched. Different from traditional seismic structures and seismic isolation structures, the recoverable structures have better deformation capacity and more reasonable failure sequence in the earthquake, and the seismic performance of the structures can be restored through simple repair or replacement of energy dissipation components after the earthquake. Therefore, the recoverable structures have good application prospects and are expected to be widely applied.

[0003] Replaceable coupling beams and replaceable spring dampers are common forms of replaceable components. The design concept of replaceable coupling beams and replaceable spring dampers is to design the coupling beams and wall foot parts of traditional cast-in-place shear walls as replaceable structural components. It is known that the coupling beams and wall foot parts of traditional cast-in-place shear walls are severely damaged and difficult to repair under the action of the earthquake. Compared with traditional cast-in-place shear walls, the shear walls containing replaceable components such as replaceable coupling beams and replaceable spring dampers can concentrate the damage of the wall body on the replaceable components. In this way, not only can the repair and replacement work after the earthquake be better supported, but also the setting of the replaceable components itself improves the deformation resistance of the shear wall, thereby reducing the residual deformation of the wall body after the earthquake.

[0004] A common structural form of the shear wall containing replaceable components is that the rest of the wall body except the replaceable parts is integrally cast. In this way, the following problems exist: a considerable amount of wet work needs to be carried out on site, which will consume construction time and labor. The connecting structure for connecting the replaceable components needs to be pre-buried in the wall body, and it is difficult to ensure the positioning accuracy of the pre-buried operation on site, so the use performance of the shear wall containing replaceable components will be affected to some extent. In addition, due to the uncertainty of the intensity of the earthquake action, the concrete of the integrally cast area near the replaceable components (replaceable spring dampers) at the bottom of the wall body will appear serious crushing and other damage phenomena under the condition of a large inter-story drift angle. The damage phenomenon of the bottom integrally cast area concrete may lead to the decrease of the overall performance of the shear wall containing replaceable components and the defect that the damage is not easy to repair. SUMMARY

[0005] In order to solve at least part of the above problems, the present application is proposed.

[0006] The first aspect of the present application provides a full dry energy dissipation connection assembly type shear wall system with recoverable functions, comprising: prefabricated combined shear wall bodies, prefabricated shear wall corner columns, prefabricated strip foundations, replaceable wall foot components, and replaceable prefabricated soft steel coupling beams, wherein the prefabricated combined shear wall bodies with included angles are connected by the prefabricated shear wall corner columns; wherein the prefabricated combined shear wall body located at the bottom layer is arranged on the prefabricated strip foundation; and wherein the replaceable wall foot components are arranged between the prefabricated combined shear wall bodies adjacent in the vertical direction and / or between the prefabricated combined shear wall body at the bottom layer and the prefabricated strip foundation.

[0007] Through such a structure, a specific structural formation of the shear wall system is given.

[0008] Based on the above structure, when the wall body of the full dry energy dissipation connection assembly type shear wall system with recoverable functions is damaged under strong earthquake action, the structure of the wall system can be restored to the original functional level after the earthquake by replacing the replaceable spring damper and the replaceable prefabricated soft steel coupling beam. In addition, through the arrangement of replaceable components and the matching connection between replaceable components and non-replaceable components and parts, the shear wall has three seismic defense lines (the replaceable spring damper is the first defense line, the replaceable prefabricated soft steel coupling beam is the second defense line, and the non-replaceable area is the third defense line), and has more excellent deformation capacity and more reasonable failure sequence, which ensures the seismic safety of the structure. In addition, the wall body of the shear wall, the replaceable wall foot component, the replaceable prefabricated soft steel coupling beam and the prefabricated profiled steel plate composite floor are designed and prefabricated in advance, without wet work on site. In this way, all connections on site are dry connections, i.e. mainly assembly operation, so it has the advantages of small amount of work, high installation efficiency and low construction cost.

[0009] For the above full dry energy dissipation connection assembly type shear wall system, in a possible implementation, the prefabricated combined shear wall body comprises a reinforced shear wall body, two H-shaped steel columns respectively located at both sides of the reinforced shear wall body in the horizontal direction, and two square steel tube concretes respectively located at both sides of the reinforced shear wall body in the vertical direction.

[0010] Through such a structure, a possible structural form of the prefabricated combined shear wall body is given.

[0011] Specifically, in the prefabrication process, the two H-shaped steel columns are welded and fixed with the horizontal steel bars in the reinforced shear wall body, and the square steel pipes in the two square steel tube concretes are welded and fixed with the vertical steel bars in the reinforced shear wall body.

[0012] For the full dry energy dissipation connecting assembly type shear wall system, in a possible implementation, the prefabricated combined shear wall body comprises a waterproof and heat insulation integrated board, and the waterproof and heat insulation integrated board is fixed on both sides of the prefabricated combined shear wall body through the embedded connecting piece in the steel reinforced shear wall body.

[0013] Through such a structure, a specific structure of the prefabricated combined shear wall body is given.

[0014] It can be seen that after the concrete is poured, the H-shaped steel column, the concrete-filled square steel tube, the steel reinforced shear wall body and the waterproof and heat insulation integrated board form a whole. On the one hand, during the pouring process, the H-shaped steel column, the concrete-filled square steel tube and the waterproof and heat insulation integrated board can replace the role of the formwork. On the other hand, compared with the traditional reinforced concrete shear wall, the reinforcement ratio can be appropriately reduced.

[0015] For the full dry energy dissipation connecting assembly type shear wall system, in a possible implementation, the prefabricated shear wall corner column comprises an L-shaped reinforced concrete column, two H-shaped steel columns located at two side edges of the L-shaped reinforced concrete column, and two concrete flanges located at two ends of the L-shaped concrete column along the height direction.

[0016] Through such a structure, a possible structure of the prefabricated shear wall corner column is given.

[0017] Specifically, during the prefabrication, the two H-shaped steel columns located at the two side edges of the L-shaped reinforced concrete column are welded and fixed with the horizontal steel bars in the L-shaped reinforced concrete column. After the concrete is poured, the concrete flange, the H-shaped steel column and the L-shaped reinforced concrete column form a whole, which is convenient for later on-site assembly and connection.

[0018] For the full dry energy dissipation connecting assembly type shear wall system, in a possible implementation, the prefabricated strip foundation is provided with a concrete flange on the upper side, and the prefabricated combined shear wall at the bottom layer is connected with the concrete flange.

[0019] For the full dry energy dissipation connecting assembly type shear wall system, in a possible implementation, the replaceable wall foot part is a replaceable spring damper.

[0020] Through such a structure, a possible form of the replaceable wall foot part is given.

[0021] For the full dry type energy dissipation connection assembly type shear wall system, in a possible implementation, the replaceable spring damper includes a damping spring, a rubber non-slip pad, a first perforated end plate, and a shell, wherein the damping spring is arranged between two first perforated end plates, and a rubber non-slip pad is arranged between each end of the damping spring and the corresponding end first perforated end plate, and the shell is arranged on the circumferential outer side of the damping spring between the two first perforated end plates.

[0022] Through such a configuration, a specific structural form of the replaceable spring damper is given, such as the two first perforated end plates above and below and the H-shaped steel columns on both sides of the composite shear wall connected by energy dissipation bolts. In this way, when the earthquake load acts, the spring damper is deformed under tension and compression, thereby dissipating seismic energy and reducing the damage of the main structure to the earthquake. In addition, the spring damper can also have a certain self-resetting function after the earthquake, and such a structure is convenient for replacement after the earthquake.

[0023] For the full dry type energy dissipation connection assembly type shear wall system, in a possible implementation, the replaceable precast soft steel coupling beam includes a soft steel energy dissipation damper and a second perforated end plate.

[0024] Through such a configuration, a specific structural form of the replaceable precast soft steel coupling beam is given.

[0025] For the full dry type energy dissipation connection assembly type shear wall system, in a possible implementation, the shear wall system includes a precast profiled steel plate composite floor slab, which is lapped between the precast composite shear wall bodies with an included angle.

[0026] Through such a configuration, the precast profiled steel plate composite floor slab is given.

[0027] It can be seen that the precast profiled steel plate composite floor slab is similar in structure to the traditional precast floor slab, except that the precast profiled steel plate composite floor slab can be directly lapped in the protruding flange part of the precast composite shear wall body, such as the precast profiled steel plate composite floor slab can be connected with the shear wall flange by welding.

[0028] The second aspect of the present application provides a construction method of a full dry energy dissipation connecting assembly type shear wall system with recoverable function, which comprises the following steps: obtaining a prefabricated combined shear wall body, a prefabricated shear wall corner column, a prefabricated strip foundation, a replaceable spring damper, a replaceable prefabricated soft steel coupling beam and a prefabricated profiled steel plate composite floor slab; arranging the prefabricated combined shear wall body of the bottom layer above the prefabricated strip foundation and connecting the two through energy dissipation bolts; arranging the replaceable spring dampers at the upper and lower ends of the H-shaped steel column in the prefabricated combined shear wall body of the bottom layer, and connecting the upper and lower first perforated end plates of the replaceable spring dampers with the H-shaped steel column of the prefabricated combined shear wall body of the upper layer and the upper flange of the prefabricated strip foundation through energy dissipation bolts; arranging the prefabricated combined shear wall body of the upper layer above the prefabricated combined shear wall body of the bottom layer, and connecting the square steel tube concrete at the upper end of the prefabricated combined shear wall body of the bottom layer with the square steel tube concrete at the lower end of the prefabricated combined shear wall body of the upper layer through energy dissipation bolts; installing the replaceable prefabricated soft steel coupling beam between the two prefabricated combined shear wall bodies adjacent in the horizontal direction, and connecting the second perforated end plates at the two ends of the replaceable prefabricated soft steel coupling beam with the H-shaped steel columns of the corresponding prefabricated combined shear wall bodies through energy dissipation bolts; and overlapping the prefabricated profiled steel plate composite floor slab to the square steel tube concrete at the lower end of the prefabricated combined shear wall body, and welding the square steel tube concrete and the prefabricated profiled steel plate composite floor slab.

[0029] Through such a configuration, a possible construction method of forming a full dry energy dissipation connecting assembly type shear wall body with recoverable function is given.

[0030] In summary, in a preferred embodiment, the full dry energy dissipation connecting assembly type shear wall system of the present application can achieve the beneficial effects including:

[0031] The present application can realize reliable and rapid assembly connection between prefabricated components, effectively solving the problems of large amount of field wet work, time-consuming construction and complex assembly in the existing recoverable function assembly type shear wall connection technology. In the present application, all components are connected by dry connection, which is simple to operate, has small workload and controllable connection quality, improves the construction efficiency and reduces the construction cost while improving the structural safety. The present application has good deformation capacity and energy dissipation capacity. The replaceable spring damper, the replaceable coupling beam and the H-shaped steel column are connected by energy dissipation bolts, which can yield and produce plastic deformation to dissipate seismic energy under the action of earthquake. The replaceable spring damper adopts a spring damper, which not only has good tensile and compressive mechanical properties, but also has good energy dissipation capacity. The replaceable coupling beam can provide sufficient stiffness to the structure in the elastic stage, yield under the action of strong earthquake and produce plastic deformation to dissipate seismic energy. Through the replaceable components, the matching (connection) of the replaceable components and the non-replaceable components provides triple protection for the safety of the structure.

[0032] The application can realize modular production and assembly construction of the structure. The components of the application can be prefabricated in a factory, effectively ensuring the processing quality of the components; the components after prefabrication can be assembled through bolt connection and welding at the construction site, greatly reducing the labor and time cost, and improving the construction speed of the structure. The application meets the requirements of the national promotion of building industrialization, and is easy to popularize and apply. BRIEF DESCRIPTION OF DRAWINGS

The recoverable full dry energy dissipation connecting assembly shear wall system according to the present application will be described below with reference to some or all of Figures 1 to 6

[0068] Fig. 1, Figure 1 In one possible embodiment, the structure of the recoverable full dry energy dissipation connecting assembly shear wall system 100 mainly includes a prefabricated combined shear wall body 1, a prefabricated shear wall corner column 2, a prefabricated strip foundation 3, an energy dissipation bolt 4 (in order to facilitate description, the present application does not distinguish the energy dissipation bolts in different positions and connection relationships, and only takes it as a kind of fastener which can be flexibly selected in terms of model, number and mounting position), a replaceable spring damper 5, a replaceable prefabricated mild steel coupling beam 6 and a prefabricated profiled steel plate composite floor 7, wherein:

[0069] ​The plurality of prefabricated composite shear wall bodies 1 are arranged according to the expected structure of the wall system. The relative position relationship between the plurality of prefabricated composite shear wall bodies 1 can be described by rows and columns. As shown in the embodiment shown in Figure 1 The left cavity includes two rows and two columns of prefabricated composite shear wall bodies 1, the prefabricated composite shear wall bodies 1 at the bottom and the prefabricated composite shear wall bodies 1 at the upper layer form two rows, and the two groups of prefabricated composite shear wall bodies 1 arranged horizontally form two columns.

[0070] The prefabricated composite shear wall body 1 at the bottom is arranged above the prefabricated strip foundation 3. The concrete-filled square steel tube 11 below the prefabricated composite shear wall body 1 is connected to the strip foundation upper flange 15 of the prefabricated strip foundation 3 through the energy dissipation bolt 4. The upper and lower two first opening end plates 181 of the replaceable spring damper 5 are respectively connected to the lower end of the H-shaped steel column 9 of the prefabricated composite shear wall body 1 arranged above the prefabricated composite shear wall body 1 at the bottom (arranged above the prefabricated composite shear wall body 1 at the bottom, same column and different row) and the strip foundation upper flange 15 of the prefabricated strip foundation 3 through the energy dissipation bolt 4. The concrete-filled square steel tubes 11 of the (upper and lower) layer prefabricated composite shear wall bodies 1 are connected through the energy dissipation bolt 4. The replaceable spring damper 5 is connected to the H-shaped steel column 9 of the (upper and lower) layer prefabricated composite shear wall bodies 1 through the energy dissipation bolt 4.

[0071] The H-shaped steel columns 9 of the two prefabricated composite shear wall bodies 1 (different columns in the same row) in the horizontal direction are connected into a whole through the energy dissipation bolt 4.

[0072] The replaceable prefabricated soft steel coupling beam 6 is arranged between the two prefabricated composite shear wall bodies 1 adjacent in the horizontal direction and is connected to the H-shaped steel columns 9 of the two prefabricated composite shear wall bodies 1 through the energy dissipation bolt 4.

[0073] The prefabricated shear wall corner column 2 at the bottom is arranged above the prefabricated strip foundation 3. The concrete flange 13 at the lower end of the prefabricated shear wall corner column is connected to the strip foundation upper flange 15 through the energy dissipation bolt 4.

[0074] The prefabricated shear wall corner column 2 at the upper layer is arranged above the prefabricated shear wall corner column 2 at the bottom. The concrete flange 13 at the lower end of the prefabricated shear wall corner column at the upper layer is connected to the concrete flange 13 at the upper end of the prefabricated shear wall corner column at the bottom through the energy dissipation bolt 4.

[0075] The prefabricated shear wall corner column 2 is connected to the H-shaped steel columns 9 of the two prefabricated composite shear wall bodies 1 through the energy dissipation bolt 4, so that the prefabricated shear wall corner column 2 and the prefabricated composite shear wall body 1 form a whole.

[0076] The prefabricated profiled steel plate composite floor 7 is overlapped to the top of the concrete-filled square steel tube 11 arranged at the lower end of the prefabricated composite shear wall body 1, and the prefabricated profiled steel plate composite floor 7 and the concrete-filled square steel tube 11 are welded at the flange position.

[0077] It can be seen that, in the full dry energy dissipation connecting fabricated shear wall system with recoverable function, the connection between the components is safe and reliable, the stress path is clear and simple, the internal force of the structure can be effectively transmitted, the structural damage can be guided to the expected position of the replaceable component under the action of the earthquake, and the seismic energy can be dissipated through the deformation of the replaceable component, so as to ensure that the main body part of the full dry energy dissipation connecting fabricated shear wall system is not damaged or only has a digestible or allowed slight damage. In addition, dry connection is adopted between the replaceable component and the main body part, which can reduce the pollution caused by wet work on site, and facilitate the replacement operation after the earthquake.

In the prefabrication process, the H-shaped steel column 9 is welded to the two sides of the reinforced shear wall body 8 along the horizontal direction, and the flange width of the H-shaped steel column 9 is not less than the thickness of the reinforced shear wall body 8.

After the concrete is poured, the reinforced shear wall body 8, the H-shaped steel column 9, and the concrete-filled square steel tube 11 form an integral whole. Preferably, the stiffening rib 10 is additionally arranged at the position of the H-shaped steel column 9 connected with the replaceable prefabricated mild steel coupling beam 6, so as to ensure that the H-shaped steel column 9 does not fail under the action of the earthquake. Based on such a structure, on the one hand, the H-shaped steel column and the square steel tube can replace a part of the formwork during pouring; on the other hand, the prefabricated composite shear wall body 1 can facilitate the later on-site assembly connection and the related insulation and waterproof panel connection.

After the concrete is poured, the two H-shaped steel columns 9, the L-shaped corner column 12 and the concrete flanges 13 at the two ends (the upper end and the lower end in the figure) of the L-shaped corner column 12 form an integral whole. Based on such a structure, the H-shaped steel column 9 and the concrete flange 13 contained in the prefabricated shear wall corner column 2 can be conveniently assembled and connected on site later.

Obviously, the height of the replaceable spring damper 5 and the size of the perforated end plate 18 can be adjusted according to actual needs.
