Description

Technical Field

[0001] The present invention relates to the technical field of shear walls, and in particular to an assembled energy-absorbing shear wall and a construction method thereof. Background Art

[0002] Traditional composite shear walls are generally composed of two layers of prefabricated concrete panels, which are connected to form a wall panel component with an intermediate cavity through truss steel bars or connectors. After on-site installation, concrete is poured to fill the intermediate cavity to form a concrete wall panel. In terms of structural performance, there are mainly disadvantages such as weak vertical connections and a single seismic defense line. In recent years, with the development of technology, steel plate concrete shear walls have emerged. Steel plate concrete shear walls are a type of shear wall that adds steel plates, steel sections or other steel components to cast-in-place concrete shear walls. For example, the patent with application publication number CN 116378300 A proposes a stamped steel plate skeleton composite shear wall prefabricated component, connector and production method, including a first wall and a second wall arranged along a first direction, formed by concrete pouring; the first wall and the second wall are arranged in parallel and spaced apart to form a cavity, and a stamped steel plate skeleton is arranged between the first wall and the second wall. Although the shear wall adopts a stamped steel plate skeleton, has a higher bearing capacity and anti-lateral deformation capacity, and improves the ductility and energy consumption of the shear wall, it still has the following problems:

[0003] 1. The production method of the above-mentioned composite shear wall is recorded in its instruction manual as follows: "S7: Place the stamped steel plate frame on the formwork table, and support the side mold on the formwork table; S8: Pour concrete and cure to the specified strength; S9: Support the side mold on another formwork table, pour concrete, and then use a turning machine to turn the component 180° and insert it into the unsolidified concrete; S10: Cure to the specified strength." It can be seen that the existing process requires the use of a special turning machine, which has complex equipment, high investment, and increased cost.

[0004] 2. When assembling the above-mentioned shear walls, there is a lack of effective vertical connection structure between the shear walls of the upper and lower layers, and there is also a lack of effective horizontal connection between the left and right shear walls, resulting in poor integrity and low bearing capacity. The ductility and energy consumption performance of the shear walls cannot be effectively improved, and the seismic performance needs to be improved. Summary of the invention

This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0050] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0051] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0052] Embodiment 1:

[0053] like Figure 1 - Fig.10 As shown, this embodiment proposes an assembled energy-absorbing shear wall, including a plurality of assembled shear wall units, wherein the shear wall unit includes an inner wall panel 1 and an outer wall panel 2 arranged at intervals, and a steel plate assembly is provided in the cavity between the inner wall panel 1 and the outer wall panel 2, the steel plate assembly includes a first I-beam 3 and a second I-beam 4 that can be adaptably and detachably connected to the first I-beam 3, one end of the first I-beam 3 is pre-embedded and fixed in the inner wall panel 1, and the other end of the first I-beam 3 is fixedly connected to a plurality of plug-in columns 5 arranged up and down to form a first component.

[0054] One end of the second I-beam 4 is pre-buried and fixed in the exterior wall panel 2, and the other end of the second I-beam 4 has a guide hole (not shown in the figure) that can be plugged in with the plug-in connector to form a second component.

[0055] In this embodiment, the first I-beam 3 and the second I-beam 4 are both conventional structures, and the main structures of the two are the same, both of which include a web 31, and the two ends of the web 31 are respectively fixedly connected with wing plates, and the wing plates and the web 31 located in the middle form an I-shaped structure; the difference is that a plurality of plug-in columns 5 are fixedly connected to the wing plate at one end of the first I-beam 3, and the fixed connection method includes but is not limited to welding, bolting, bonding, clamping, etc. In order to eliminate the residual stress caused by welding, in this embodiment, the bolting method can be preferably used.

[0056] After the first component and the second component are assembled, they are fixed together by a locking member 7. The locking member 7 is arranged in the cavity to realize the splicing between the first I-beam 3 and the second I-beam 4, so as to form a shear wall unit; concrete is poured in the internal cavity of the shear wall unit to form an assembled energy-absorbing shear wall.

[0057] Regarding the locking member 7, the following structural forms can be adopted:

[0058] The locking member 7 includes a strip plate 71, which is provided with a plurality of slots 72 arranged up and down, and the slots 72 are L-shaped, including a transverse slot and a vertical slot connected to the transverse slot; a wedge block 73 is provided on one side of the top of the strip plate 71; the plug-in column 5 is provided with a notch, and the slots 72 can be adapted to be plugged into the notch; the side of the wedge block 73 is pressed on the second I-beam 4, so as to achieve tight pressing of the strip plate 71 and the plug-in column 5, complete the positioning of the locking member 7, thereby effectively eliminating the gap between the first I-beam 3 and the second I-beam 4, ensuring a tight connection between the first I-beam 3 and the second I-beam 4, and preventing the locking member 7 from shifting due to factors such as bumps during transportation, and failing to achieve a tight connection between the first I-beam 3 and the second I-beam 4. In this way, it can be ensured that the shear wall units after splicing and connection have excellent seismic resistance, and can effectively resist vibrations during the pouring process and vibrations during transportation, thereby ensuring consistent product quality after leaving the factory and preventing product quality problems.

[0059] In this embodiment, the inner wall panel 1 and the outer wall panel 2 are made of ultra-high performance concrete. That is, UHPC prefabricated panels are used. UHPC prefabricated panels are a type of wall panel made of ultra-high performance concrete (UHPC). It has the following characteristics:

[0060] 1. Lightweight: Due to the use of lightweight materials, the weight of the wall panels is reduced, reducing the cost and weight of the building.

[0061] 2. High strength: Compared with ordinary concrete, UHPC has higher strength and durability, can effectively resist the erosion of the natural environment and chemicals, and ensures its service life.

[0062] 3. High durability: UHPC precast panels have excellent shear bearing capacity and long service life.

[0063] 4. High energy-saving performance: UHPC has excellent thermal insulation performance, which can effectively reduce the energy consumption of buildings and improve energy utilization efficiency.

[0064] In addition, as a feasible embodiment, the inner wall panel 1 and the outer wall panel 2 may also adopt FC panels, namely fiber cement panels, also known as fiber reinforced cement panels, which have the following characteristics:

[0065] 1. Fireproof insulation: non-flammable Class A, the board will not burn and will not produce toxic smoke when a fire occurs; low conductivity, it is an ideal insulating material.

[0066] 2. Waterproof and moisture-proof: In semi-open air and high humidity environments, it can still maintain stable performance without sinking or deformation.

[0067] 3. Heat insulation and sound insulation: low thermal conductivity, good heat insulation performance, high product density and good sound insulation.

[0068] 4. Lightweight and high strength: high strength, not easy to deform or warp.

[0069] 5. Ultra-long service life: It is resistant to acid and alkali, corrosion, moisture, insects and ants, and its strength and hardness increase over time, ensuring an ultra-long service life.

[0070] It can be seen that:

[0071] The shear wall unit designed in the present invention forms two groups of independently produced first components and second components, which can be prefabricated and processed separately during processing, effectively improving production efficiency; the first I-beam 3 and the second I-beam 4 are both finished products, which only need simple processing after purchase to meet the use requirements, without the need for complex processing technology, and can effectively control costs.

[0072] The composite wall panels are formed by a splicing installation method. Such a structure means that it is no longer necessary to use expensive flipping equipment for flipping during production, which reduces equipment investment and overall production costs. At the same time, the assembly is simple, and the connection is completed by a locking member 7. The construction is convenient and fast, and can effectively improve the work efficiency. In addition, the first I-beam 3 and the second I-beam 4 are spliced, and an assembled connection method is adopted instead of welding. This can eliminate the residual stress generated during the welding process, prevent the shear wall from deforming during the welding process, and is beneficial to improving the strength of the shear wall. Compared with the traditional double-skin wall, the present invention has a fast forming speed, high quality, simple production, convenient construction, and can be produced using simple equipment.

[0073] The first I-beam 3 and the second I-beam 4 are used to form a design of vertically closely spaced connecting columns and shear energy dissipation steel plates, which has excellent overall mechanical properties, can achieve a large deformation capacity of the shear wall, and significantly improve its overall energy dissipation capacity.

[0074] Embodiment 2:

[0075] like Figure 1 - Fig.10 As shown, on the basis of Example 1, in order to further improve the overall performance, the web 31 of the first I-beam 3 and / or the second I-beam 4 is provided with a plurality of mounting holes 8 spaced apart from each other, and transverse reinforcements 6 are inserted into the mounting holes 8; both ends of the transverse reinforcements 6 extend outside the shear wall unit and are arranged in an exposed shape. In this embodiment, a design method of "post-through transverse reinforcements 6" is introduced, and the number of through-insertion of the transverse reinforcements 6 can be adjusted according to design requirements. The transverse reinforcements 6 can be added or deleted according to different construction environments, which is convenient for adjustment and suitable for different working conditions.

[0076] Embodiment 3:

[0077] like Figure 1 - Fig.10As shown, on the basis of Example 2, the shear wall unit also includes an interlocking member for connecting the upper and lower shear walls, and the interlocking member includes a positioning plate 9 and a pull rod 10, wherein the positioning plate 9 is provided with a vertical through hole 91, and a threaded column 92 is fixedly connected to the bottom surface of the positioning plate 9, and the threaded column 92 is arranged in an L shape; the web 31 of the first I-beam 3 and / or the second I-beam 4 is provided with a plurality of sockets 311 and transverse through holes 312, and some of the sockets 311 are provided for the positioning plate 9 to be inserted and connected; it should be noted that the redundant sockets 311 can be used as a concrete flow cavity during pouring, so as to realize the effective connection between the steel plate components and the concrete and improve the overall strength.

[0078] The transverse through hole 312 is for the threaded column 92 to be inserted and connected, and is used as a positioning point; it also includes a first nut 93 threadedly connected to the threaded column 92, which is used to achieve bolted fixation of the threaded column 92 and the web 31; when in use, after the threaded column 92 is inserted into the transverse through hole 312, the first nut 93 is screwed on, and the threaded column 92 is fixed by bolting, thereby completing the positioning of the positioning plate 9.

[0079] The bottom of the pull rod 10 has a hook for realizing a hook connection with the transverse reinforcement 6 located in the lower shear wall unit a1; the positioning plate 9 is connected to the web 31 located in the upper shear wall unit a2, and the pull rod 10 is provided with a threaded section on the outer wall of the rod body near the top; the top end of the pull rod 10 passes through the vertical through hole 91 and is threadedly connected with a second nut 1001. When the second nut 1001 is tightened, the hook realizes an effective connection between the transverse reinforcement 6 and the positioning plate 9, connecting them as a whole.

[0080] Application results:

[0081] The present invention realizes the tensioning and fixing between the upper and lower shear walls through the designed interlocking parts. The assembly is fast and convenient. The bolted fixing method is adopted, and welding is not required. The residual stress generated by welding can be effectively eliminated, and the overall strength and reliability are effectively improved. The present invention has good integrity and reasonable structural force, and the anti-buckling bearing capacity, anti-shearing capacity and stability of the shear wall are improved, and the service life is extended. The steel skeleton formed inside works in coordination with the concrete, which effectively improves the ductility and energy consumption of the shear wall.

[0082] Embodiment 4:

[0083] Continue to refer to the attached Figure 1 - Fig.10 This embodiment also proposes a construction method of an assembled energy-absorbing shear wall, which is used to construct the assembled energy-absorbing shear wall proposed in Example 2, and includes the following methods:

[0084] S1, Processing and Production:

[0085] The first component, the second component and the locking member 7 are processed and formed in the factory in advance;

[0086] S2, assembly:

[0087] The first component and the second component are assembled together, and the first I-beam 3 and the second I-beam 4 are connected by using the locking member 7. The specific process is as follows: the position of the first component is adjusted so that the plug-in column 5 is aligned with the guide hole, and then the first component is moved so that one end of the plug-in column 5 passes through the guide hole; then, the locking member 7 is extended into the cavity of the shear wall unit, and the position of the locking member 7 is adjusted, and the card slot 72 of the locking member 7 is adjusted to the position corresponding to the plug-in column 5; the locking member 7 is moved, and the plug-in column 5 first enters The locking member 7 is then pressed down, and the plug-in column 5 moves from the horizontal groove to the vertical groove relative to the locking member 7; then, the top of the locking member 7 is knocked, and the locking member 7 moves downward, and the locking groove 72 is engaged with the groove 51 of the plug-in column 5; at the same time, under the inclined guiding action of the wedge block 73, the wedge block 73 is tightly pressed against the second I-beam 4, so that the position of the locking member 7 is positioned and fixed to prevent movement; at this point, the shear wall unit is assembled, and this step is repeated to complete the assembly of multiple shear wall units;

[0088] S3, On-site construction:

[0089] The assembled shear wall unit is transported to the construction site; the shear wall unit is installed at the construction site according to the designed position; the transverse reinforcement 6 is installed through the installation hole 8 of the shear wall unit, and the transverse reinforcement 6, the first I-beam 3 and the second I-beam 4 together form a steel skeleton; finally, concrete is poured in the cavity of the installed shear wall unit to form an assembled energy-absorbing shear wall.

[0090] Embodiment 5:

[0091] Continue to refer to the attached Figure 1 - Fig.10 This embodiment proposes another construction method of assembled energy-absorbing shear wall. The method steps in S1-S2 are the same as those in Example 4. The difference is that the assembly between the shear wall units in S3 is specifically as follows:

[0092] First, when assembling the transverse shear wall units, two adjacent groups of shear wall units are spaced apart, such as forming an installation area between the left shear wall unit b1 and the right shear wall unit b2; a template c1 is set at the edge of the installation area, and the template c1 connects the two adjacent groups of shear wall units into one; then a pre-made steel cage d1 is placed in the installation area, and the steel cage d1 is connected and fixed to the transverse bars 6 on the left and right sides; finally, concrete is poured in the cavity of the installed shear wall unit to form an assembled energy-absorbing shear wall; it should be noted that since the transverse bars 6 in this solution are installed later, it is convenient to move and adjust the position. Therefore, when installing the steel cage d1, if there is interference with the position of the transverse bars 6, the transverse bars 6 can be moved first to leave operating space, and after the steel cage d1 is lowered, the position of the transverse bars 6 can be adjusted to the designed position.

[0093] Secondly, when assembling the vertical shear wall units, the shear wall units on the upper and lower layers are connected together through interlocking parts. The specific method is as follows:

[0094] ① Position and install the lower shear wall unit a1;

[0095] Insert the corresponding transverse reinforcement 6 into the lower shear wall unit a1;
