Description

Technical Field

[0001] This invention relates to the field of building engineering structures, specifically to a fully bolted frame shear wall structure system and its installation method. Background Technology

[0002] In recent years, with the further deterioration of environmental pollution, people have put forward new requirements for the sustainable development of the construction industry. Prefabricated concrete structures have received increasing attention because they can reduce the pollution caused by on-site construction.

[0003] Taking prefabricated concrete shear wall structures as an example, the connections between adjacent shear walls mainly include two categories: "wet connections" and "dry connections." In "wet connections," the longitudinal reinforcement is connected by grouting sleeves, hoop connections, and grout anchor connections, and the concrete components are partially cast on-site. In "dry connections," the longitudinal reinforcement is connected by welding, bolting, and prestressing. However, these connection methods have a significant impact on the assembly efficiency and seismic performance of the structure, and the diversity and complexity of the connection methods of the components increase the difficulty of modular production and on-site assembly. It can be seen that the application of prefabricated concrete structures in actual engineering still faces the following challenges: (1) The prefabricated structural connections are too complex, and the efficiency of on-site hoisting construction needs to be improved. (2) The seismic performance of prefabricated concrete structures needs to be improved so that they can be used in high-intensity seismic areas. Summary of the Invention

[0004] Purpose of the invention: The purpose of this invention is to provide a fully bolted frame shear wall structure system and installation method. This solution can improve the force transmission mechanism of existing prefabricated concrete structure systems, which is conducive to improving the lateral resistance of prefabricated concrete structure systems, while ensuring that no additional component cross-section is required, facilitating the industrial production of components and improving the on-site assembly rate.

[0005] Technical Solution: The structural system of this invention includes column modules, shear wall modules, precast floor slab modules, connectors, and a foundation structure. The connectors include bolts and third steel plates. Several column modules are connected to both sides of the shear wall modules. A third steel plate is fixedly installed on the outer side of two adjacent column modules in the vertical direction, connecting them securely. Several shear wall modules are arranged in several layers along a pre-designed wall, with adjacent layers having matching upper and lower shear wall modules designed and fixedly installed with bolts. The shear wall modules are categorized according to their installation position as first-floor shear wall modules, standard-floor shear wall modules, and top-floor shear wall modules. The precast floor slab modules are positioned above each layer of shear wall modules and are installed in conjunction with the top of the shear wall modules using bolts. The foundation structure includes independent foundations for the column modules and foundation beams for the shear wall modules. The independent foundations for the column modules are connected below the bottommost column modules, and the foundation beams for the shear wall modules are connected below the bottommost shear wall modules.

[0006] It also includes a connecting beam module, which is set inside the shear wall module and its two ends are fixedly connected to the shear wall module by bolts.

[0007] The connecting beam module includes a second steel plate, a wooden beam, and a bolt. Several fourth bolt holes are provided on both the second steel plate and the wooden beam. The wooden beam is arranged between two adjacent second steel plates, and the bolt passes through the fourth bolt holes to form a composite beam component.

[0008] It also includes an arched support module, which is arranged at the node where the column module and the shear wall module intersect, and connects the adjacent column modules and shear wall modules into a whole by bolts.

[0009] The arched support module includes a steel pipe joint, a second longitudinal reinforcement, a spiral stirrup, an end plate, and a second concrete. Several second longitudinal reinforcements pass through the spiral stirrups to form a reinforcing cage, which is filled with the second concrete. The two ends of the reinforcing cage are fixedly connected to the end plate through the steel pipe joint. The end plate is used to connect the column module and the shear wall module.

[0010] The column module includes reinforcing bars, first concrete, first embedded bolts, embedded steel plates, and embedded angle steel. The reinforcing bars, embedded steel plates, and embedded angle steel are all embedded in the first concrete precast into a column-shaped structure. The reinforcing bars include first longitudinal bars and stirrups, with the stirrups winding multiple first longitudinal bars to form a whole. The embedded steel plates and embedded angle steels are all pre-drilled with first bolt holes. The first longitudinal bars pass through the first bolt holes of the embedded steel plates, and the embedded steel plates are connected to the shear wall modules. The first embedded bolts pass through the first bolt holes of the embedded angle steels and have a certain extension length reserved on the side wall of the column module. This reserved extension length is used to install the arched support module.

[0011] The standard floor shear wall module includes a reinforced concrete slab unit, a reinforced concrete wall unit, embedded parts, and a third bolt hole. The reinforced concrete slab unit is divided into a first top slab and a bottom slab, and the reinforced concrete wall unit is connected between the first top slab and the bottom slab. The reinforced concrete slab unit and the reinforced concrete wall unit are integrally cast-in-place structures. The reinforced concrete wall unit includes a first mortise and tenon joint and a second reserved groove. The first mortise and tenon joint is located at the bottom of the reinforced concrete wall unit, and the second reserved groove is located at the top of the wall unit. The first mortise and tenon joint and the second reserved groove are used to connect the shear wall modules of two adjacent floors in the same vertical direction. The embedded parts include a steel plate assembly, a first steel plate, and a second embedded bolt. The steel plate assembly is set on the side wall of the reinforced concrete wall unit and has a certain extension length reserved. Both the steel plate assembly and the first steel plate are provided with second bolt holes. The first steel plate is installed at both ends of the upper surface of the bottom slab, and the second embedded bolt passes through the second bolt hole on the first steel plate and has a certain extension length reserved on the surface of the reinforced concrete slab unit.

[0012] An overhanging plate is provided at the connection position between the precast floor slab module and the shear wall module. The thickness of the overhanging plate is not less than the thickness of the reinforced concrete slab unit in the shear wall module, and a sixth bolt hole is reserved in the overhanging plate. The precast floor slab module and the shear wall module are fixedly connected by bolts passing through the sixth bolt hole.

Then, fix the foundation beam of the shear wall module and the first-floor shear wall module together with the bolts in the connector and the third pre-embedded bolt.

[0021] S31: After inserting the first tenon joint in the standard floor shear wall module into the first reserved slot at the top of the first floor shear wall module, the standard floor shear wall module and the first floor shear wall module are fixedly connected by bolts;

[0022] S32: After installing the standard floor column module to the design position, bolts are passed through the embedded steel plate at the top of the first floor column module, the top plate of the first floor shear wall module, the bottom plate of the standard floor shear wall module, and the embedded steel plate at the bottom of the standard floor column module in sequence and fixedly connected; the third steel plate is installed to the side wall of the column module, and the first floor column module and the standard floor column module are further connected by the first embedded bolts;

[0030] Beneficial effects: Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0031] (1) Compared with existing prefabricated shear wall structure system and prefabricated frame-shear wall structure system, the present invention divides the traditional whole wall into several narrower wall units. These narrower wall units will undergo ideal bending deformation under lateral force, which can effectively improve the lateral resistance of the structure, which is conducive to achieving the fortification goal of "no replacement in small earthquakes", and at the same time ensures the full utilization of materials.

[0032] (2) This invention designs a coupling beam module that can serve as the first line of defense against earthquakes in this structural system. The coupling effect between these coupling beam modules and adjacent wall units can better assist the wall units in resisting bending and shear. In addition, these coupling beam modules are easy to replace, which is conducive to achieving the design goal of "reducing replacements during moderate earthquakes";

[0033] (3) The arched support module designed in this invention not only greatly reduces the assembly difficulty of adjacent column modules, but also converts the nodal internal forces at the connection between the column modules and the shear wall modules into axial forces in the arched support module. Under strong earthquakes, when the structural system loses its first seismic defense line (i.e., the connecting beam module) and the second seismic defense line (i.e., the wall unit), the column modules connected by the arched support module and the plate units in the shear wall modules can still form a frame structure system with "strong column-weak beam" stress characteristics, greatly improving the strong earthquake resistance to collapse of such structures. Therefore, the arched support module in this invention can serve as the third seismic defense line of the structural system, which is conducive to achieving the design goal of "replacing multiple modules during major earthquakes".

Several column modules 1 are connected to both sides of the shear wall modules 2, forming multiple long columns that connect the top-level precast floor slab module 5 and the bottom-level foundation structure 7. Connectors 6 include bolts 61 and third steel plates 62. Third steel plates 62 are fixedly installed on the outer sides of two adjacent column modules 1 in the vertical direction, thus connecting the two adjacent column modules 1. Several shear wall modules 2 are arranged in several layers along a pre-designed wall, with adjacent layers of shear wall modules 2 designed to match and fixedly installed using bolts 61. Connecting beam modules 3 are located inside the shear wall modules 2, with both ends fixedly connected to the shear wall modules 2 using bolts 61. Arched support modules 4 are arranged at the intersection of column modules 1 and shear wall modules 2, connecting adjacent layers of column modules 1 and shear wall modules 2 into a whole using bolts 61. The precast floor slab module 5 is positioned above the shear wall module 2 and is installed in conjunction with the top of the shear wall module 2 using bolts 61.

[0058] like Figure 2 and Figure 3 As shown, column module 1 is a precast reinforced concrete component with embedded parts, including reinforcing bars 11, first concrete 12, embedded bolts 13, embedded steel plates 14, and embedded angle steel 15.

The first embedded bolt 13 passes through the first bolt holes 16 of the embedded angle steel 15, and a certain extension length is reserved on the side wall of the column module 1 for connecting the arched support module 4.

[0059] like Figure 1As shown, shear wall module 2 is a precast reinforced concrete component with mortise and tenon joints designed for matching adjacent floors. Shear wall module 2 is divided into three categories according to its installation position: first floor shear wall module 21, standard floor shear wall module 22, and top floor shear wall module 23.

[0060] like Figures 4 to 6 As shown, the standard floor shear wall module 22 includes a reinforced concrete slab unit 221, a reinforced concrete wall unit 222, an embedded part 223, and a third bolt hole 224. The reinforced concrete slab unit 221 is divided into a first top plate 2211 and a bottom plate 2212. Multiple through holes are formed on both the first top plate 2211 and the bottom plate 2212. Bolts 61 pass through the first bolt hole 16 on the embedded steel plate 14 and the through holes on the first top plate 2211 or the bottom plate 2212, thereby achieving a fixed connection between the standard floor shear wall module 22 and the column module 1. The reinforced concrete wall unit 222 includes a first mortise and tenon joint 2221 and a second reserved groove 2222. The first mortise and tenon joint 2221 is located at the bottom of the reinforced concrete wall unit 222, and the second reserved groove 2222 is located at the top of the reinforced concrete wall unit 222. The first mortise and tenon joint 2221 and the second reserved groove 2222 are used to connect the shear wall modules 2 of two adjacent floors in the same vertical direction.

[0061] like Figure 15-18 As shown, the first-floor shear wall module 21 and the top-floor shear wall module 23 have basically the same structure as the standard floor shear wall module 22.

[0067] like Figure 8-12As shown, the installation process of the arch support module 4 is as follows: one end of the arch support module 4 is fixedly connected to the pre-embedded bolt 13 of the column module 1, and the other end of the arch support module 4 is fixedly connected to the standard floor shear wall module 22 through the second pre-embedded bolt 2233.

[0068] like Figure 15-17 As shown in Figures 19-21, the first-floor installation process of the all-bolted frame shear wall structure system is as follows: After inserting the bottom of the first-floor column module 1 into the wedge-shaped groove 711 of the column module independent foundation 71, concrete is poured into the wedge-shaped groove 711 to fix the first-floor column module 1 to the column module independent foundation 71; the third pre-embedded bolt 721 in the shear wall module foundation beam 72 passes through the bolt hole reserved on the plate unit in the first-floor shear wall module 21, and the second tenon joint 722 in the shear wall module foundation beam 72 is inserted into the first reserved groove 2 at the bottom of the first-floor shear wall module 21.

[0069] like Figure 8-14 , Figure 21 As shown, the standard floor installation process of the all-bolted frame shear wall structure system is as follows: After inserting the first tenon joint 2221 in the upper shear wall module 22 into the second reserved slot 2222 at the top of the lower shear wall module 22, the bolt 61 is passed through the third bolt hole 224 to fix the standard floor shear wall modules 22 of the adjacent floor to each other; after installing the adjacent floor column module 1 to the designed position, the bolt 61 is passed through the embedded steel plate 14 at the top of the lower column module 1, the first top plate 2211 of the lower standard floor shear wall module 22, and the bottom plate of the upper standard floor shear wall module 22 in sequence. The pre-embedded steel plate 14 at the bottom of the plate 2212 and the upper column module 1 are fixedly connected; the third steel plate 62 is installed on the side wall of the adjacent column module 1, and the adjacent column module is further connected by the first pre-embedded bolt 13; the connecting beam module 3 and the arch support module 4 are installed respectively according to the aforementioned installation process of the connecting beam module 3 and the arch support module 4; after the prefabricated floor slab module 5 is hoisted above the standard floor shear wall module 22 of the lower floor, the overhang plate 53 is overlapped with the first top plate 2211, and the prefabricated floor slab module 5 is fixedly connected to the lower shear wall module 22 by bolts 61.

[0070] like Figure 17-18 , Figure 21As shown, the top-level installation process of the all-bolted frame shear wall structure system is as follows: After the installation of each standard floor is completed, the tenon joint in the top-level shear wall module 23 is inserted into the second reserved slot 2222 at the top of the standard floor shear wall module 22 using the above method. Then, the bolt 61 is passed through the third bolt hole 224 to fix the top-level shear wall module 23 and the standard floor shear wall module 22. After the top-level column module 1 is installed in the designed position, the bolt 61 is passed through the embedded steel plate 14 at the top of the standard floor column module 1 and the standard floor shear wall module 22 in sequence. The first top plate 2211 of the shear wall module 22 is fixedly connected; the third steel plate 62 is installed on the side wall of the column module 1, and the standard floor column module and the top floor column module are further connected by the pre-embedded bolts 13; the connecting beam module 3 and the arch support module 4 are installed respectively according to the aforementioned installation process of the connecting beam module 3 and the arch support module 4; after the precast floor module 5 is hoisted above the top floor shear wall module 23, the overhang plate 53 is overlapped with the top plate, and the precast floor module 5 is fixedly connected to the top floor shear wall module 23 by bolts 61.
