Description

Technical Field

[0001] This invention relates to the field of shear wall technology, and in particular to a high-strength seismic-resistant spliced ​​shear wall. Background Technology

[0002] Frame-shear wall, also known as frame-shear structure, is a structure in which a certain number of shear walls are arranged in a frame structure. These shear walls are called "frame-shear walls". They form flexible space utilization to meet the requirements of different building performance, while having sufficient shear walls and strong rigidity. However, while ordinary shear wall structures have higher overall strength than frame-shear wall structures, they have significant limitations during construction due to their large self-weight. For example, in the prestressed splicing construction method of prefabricated shear walls described in patent number CN104594523B, pre-reserved grouting channels 3 are arranged on both sides of the precast wall, in the same positions as the vertical reinforcement of a typical cast-in-place shear wall; first, the anchorage of the bottom end of the prestressed reinforcement 4 is completed, such as... Figure 5 As shown; the prestressed steel bars 4 of the bottom precast wall are hoisted into place from top to bottom and passed through the reserved grouting ducts 3; the prestressed steel bars 4 are extended using prestressed special connectors 5, with the joint located at the construction eye 10, and grout is injected into the reserved grouting ducts 3 to effectively bond the prestressed steel bars 4 to the component and transfer prestress; after the extension of the prestressed steel bars 4 is completed and high-strength concrete is poured into the construction eye 10, the upper precast wall can continue to be hoisted; at the horizontal joint of the intermediate layer precast shear wall, the prestressed steel bars 4 of the lower precast wall are tensioned and then anchored to the construction eye 10 on the precast wall using rigid pads 6 and prestressed tendon special anchors 8, thus completing the extension of the prestressed steel bars 4. Figure 3 As shown; after tensioning and anchoring, high-strength non-shrink grout is first injected into the reserved grouting channel 3, and then high-strength concrete is injected at the construction eye 10; after the upper layer of precast wall 2 and the lower layer of precast wall 1 are in place at the joint, elastic sealant should be applied to the sizing port 9 reserved in the precast wall to prevent water from leaking out and to prevent grout from flowing out. During the construction process, although the high strength of the shear wall is retained, its overall flexibility is poor. Meanwhile, current frame-shear wall systems, while ensuring flexibility, sacrifice structural strength, resulting in lower overall strength. For example, the prefabricated hollow column frame-shear wall structure (patent number CN115182483A) saves on-site construction time and processes compared to casting the base slab, top slab, and walls as a whole, thus improving on-site construction efficiency. The combination of prefabricated walls, steel frames, and columns, with prefabricated walls distributed around the perimeter and columns providing support on the inside, maximizes interior space utilization due to the small space occupied by the columns. (The last sentence appears to be incomplete and possibly refers to a different construction method.) The concrete grout flows into the grout sleeve through the second grout pipe, fixing the steel sleeve to the precast wall. The steel sleeve not only enhances the connection strength of the precast wall but also serves as a support for the precast roof slab, sharing the load of the precast wall. In addition, grouting inside the steel sleeve eliminates the need for formwork, further improving construction efficiency. While increasing the flexibility and construction efficiency of the frame shear wall, the overall lateral stiffness is low. In multi-story buildings, this can lead to significant lateral displacement and easily cause damage to non-structural components, affecting usability. In view of this, in-depth research was conducted on the above-mentioned problems, resulting in this case. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned problems by designing a high-strength earthquake-resistant spliced ​​shear wall, which solves the problems in the existing background technology.

One end of the reset spring is connected to the inner wall of the assembly slot, and the other end is connected to the trapezoidal block. The slot is formed on one side of the top of the lower wall panel.

[0006] The fastener has limiting grooves on both the upper and lower sides, and limiting blocks are installed at the bottom of the two connecting grooves respectively. The vertical positions of the two limiting blocks correspond to the limiting grooves on the upper and lower sides of the fastener.

[0007] Two rectangular inserts are installed on the bottom sides of the upper wall panel, and two rectangular holes are opened on the top sides of the lower wall panel, with the positions of the two rectangular holes corresponding to the positions of the two rectangular inserts.

[0008] The high-strength earthquake-resistant structure includes: a base plate, several fixing bolts, two connecting blocks, several snap-fit ​​components, four first connecting frames, four second connecting frames, and several reinforcing rods; The substrate is connected to the inner walls of both sides of the upper wall panel by a plurality of fixing bolts. Two connecting blocks are respectively installed on the front and rear sides of the substrate. A plurality of snap-fit ​​components are respectively disposed at the front end of the two connecting blocks. One end of the four first connecting brackets is respectively connected to the upper and lower sides of the two connecting blocks. The other end of the four first connecting brackets is respectively connected to the inner walls of the upper and lower sides of the upper wall panel. One end of the four second connecting brackets is respectively connected to the left and right sides of the two connecting blocks. The four second connecting brackets are respectively connected to the inner walls of the left and right sides of the upper wall panel.

[0014] A high-strength, earthquake-resistant, modular shear wall constructed using the technical solution of this invention has the following advantages: 1. Adding a splicing structure between wall panels, using auxiliary connecting components and connections between fixing parts and sliding parts, can increase the flexibility and speed of shear wall construction and ensure the stability of the splicing between shear walls during construction. 2. Compared with existing frame-shear walls, setting up a high-strength seismic-resistant structure inside the shear wall can significantly increase the overall seismic resistance and strength of the shear wall while ensuring the flexibility of splicing between shear walls and the speed of construction. This reduces the problem of low overall lateral stiffness of frame-shear walls, which can cause large lateral displacement in multi-story buildings and easily lead to the damage of non-structural components, affecting the use of the building.

[0025] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-10 As shown.

[0026] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0027] Example: According to the appendix of the instruction manual Figure 1-9 It is known that a high-strength seismic-resistant spliced ​​shear wall includes an upper wall panel 1 and a lower wall panel 2, which are connected by a splicing structure. Both the upper wall panel 1 and the lower wall panel 2 are equipped with high-strength seismic-resistant structures. According to the instruction manual Figure 1-9It can be seen that the splicing structure consists of four auxiliary connecting components, fixing parts 3, connecting protrusions 4, connecting grooves 5, two connecting slots 6, four sliding parts 7, four limiting slots 8, four first strip-shaped through holes 9, and several barbs 10. Their connection and positional relationships are as follows: Four auxiliary connecting components are respectively installed on the bottom sides of the upper wall panel 1 and the lower wall panel 2. The connecting protrusion 4 is installed on the bottom of the upper wall panel 1. The connecting groove 5 is opened on the top of the lower wall panel 2. The connecting protrusion 4 and the connecting groove 5 are inserted into each other. Two connecting slots 6 are respectively opened on the bottom of the connecting protrusion 4 and the bottom of the connecting groove 5. The two ends of the fixing member are respectively inserted into the two connecting slots 6. Four sliding members 7 are respectively slidably connected to the upper side of the two connecting slots 6. Four limiting slots 8 are respectively opened on the inner walls of the two connecting slots 6, and the lower side of the four sliding members 7 is respectively inserted into the four limiting slots 8. Four first strip-shaped through holes 9 are respectively opened on the front end of the two connecting slots 6, and the front end of the four sliding members 7 is respectively slidably connected to the four first strip-shaped through holes 9. Several barbs 10 are respectively installed on the lower side of the four sliding members 7 and the top inner wall of the four limiting slots 8. In the specific implementation process, in this technical solution, both the upper wall panel 1 and the lower wall panel 2 adopt a frame shear wall. During use, firstly, the fastener 3 is placed into the connecting groove 6 at the top of the lower wall panel 2, and the limiting groove 21 at the bottom of the fastener 3 is inserted into the limiting block 22, thus initially defining the position of the fastener 3. Then, the sliding members 7 on both sides of the top of the connecting groove 6 are moved along the first strip-shaped through hole 9, causing the lower side of the sliding member 7 to be pulled out from inside the limiting slot 8. Simultaneously, the barbs 10 on the lower side of the sliding member 7 move relative to the barbs 10 inside the limiting slot 8, thus preventing obstruction of the sliding member 7's outward sliding. After sliding out, several barbs 10 prevent the sliding member 7 from resetting. Subsequently, the connecting protrusion 4 and the two rectangular blocks 23 at the bottom of the upper wall panel 1 are aligned with the connecting groove 5 and the two rectangular insertion holes 24, respectively, and inserted. During the insertion process, the auxiliary connecting components on both sides of the bottom of the two upper wall panels 1 will connect with the top sides of the lower wall panel 2. After the insertion is completed, there will still be some gaps between the upper wall panel 1 and the lower wall panel 2. At this time, the operator moves the auxiliary connecting components on both sides of the bottom of the upper wall panel to lift it and stretch the top of the lower wall panel 2, so that the upper wall panel 1 and the lower wall panel 2 are tightly connected. At the same time, the limiting groove 21 on the top of the fixing part 3 will be inserted into the limiting insert 22 inside the connecting groove 6 at the bottom of the upper wall panel 1. Then, the operator slides the two sliding parts 7 along the two first strip through holes 9 at the bottom of the upper wall panel 1 to limit and fix the upper side of the fixing part 3, and finally completes the quick splicing connection between the upper wall panel 1 and the lower wall panel 2. The internal structure of the upper wall panel 1 and the lower wall panel 2 is the same. When splicing multiple frame shear wall panels, the above process can be repeated.

[0028] According to the instruction manual Figure 1-9It can be seen that one of the two auxiliary connecting components consists of a cavity 11, a lifting block 12, a plug rod 13, three second strip-shaped through holes 14, three limiting rods 15, several connecting springs 16, a vertical rod 17, two return springs 18, two trapezoidal blocks 19, and a slot 20. Their connection and positional relationships are as follows: Cavity 11 is opened inside the lower side of the upper wall panel 1. Lifting block 12 is set inside cavity 11. Three second strip-shaped through holes 14 are opened on lifting block 12. One end of three limiting rods 15 is welded to the inner wall of the rear side of cavity 11, and the other end is slidably connected to the three second strip-shaped through holes 14. Insert rod 13 passes through one end of cavity 11. One end of several connecting springs 16 is connected to the bottom of lifting block 12, and the other end is connected to the inner wall of the bottom of cavity 11. The top of vertical rod 17 is connected to the bottom of lifting block 12. The bottom of vertical rod 17 passes through cavity 11 and extends out from the bottom of upper wall panel 1. Two assembly slots are respectively provided on both sides of the bottom of vertical rod 17. One end of reset spring 18 is connected to the inner wall of the assembly slot, and the other end is connected to trapezoidal block 19. Slot 20 is opened on one side of the top of lower wall panel 2. In the specific implementation process, the insertion rod 13 is designed as a wedge shape, and the lifting block 12 has a protrusion on one side. When the connecting protrusion 4 at the bottom of the upper wall plate 1 and the two rectangular insertion blocks 23 are aligned with the connecting groove 5 and the two rectangular insertion holes 24 respectively, and are inserted, the bottom of the vertical rod 17 will be inserted into the slot 20. The two return springs 18 and the two trapezoidal blocks 19 cooperate to make the bottom of the vertical rod 17 engage with the slot 20. However, after the engagement is completed, there is still a gap between the upper wall plate 1 and the lower wall plate 2. At this time, the operator can insert one end of the insertion rod 13 into the cavity 11 and strike the insertion rod 13 with a hammer to make the insertion rod 13 continuously enter the cavity. Inside 11, during the insertion of the insertion rod 13, the lifting block 12 can be supported by the protrusion on one side of the lifting block 12. At this time, the three second strip-shaped through holes 14 and the three limiting rods 15 can limit the position of the lifting block 12 to prevent the position of the lifting block 12 from shifting during the lifting process. Then, through the cooperation of the vertical rod 17 and the trapezoidal block 19 that is engaged with the slot 20, the lower wall plate 2 can be pulled upward as a whole, thereby eliminating the gap that still exists between the upper wall plate 1 and the lower wall plate 2 after insertion, so that the upper wall plate 1 and the lower wall plate 2 are tightly connected. Several connecting springs 16 can generate a reaction force to increase the stability of the lifting block 12 during the movement process.

[0029] According to the instruction manual Figure 1-9 It can be seen that the high-strength seismic-resistant structure consists of a base plate 25, several fixing bolts 26, two connecting blocks 27, several snap-fit ​​components, four first connecting frames 28, four second connecting frames 29, and several reinforcing rods 30. Their connection and positional relationships are as follows: The substrate 25 is connected to the inner walls of both sides of the upper wall panel 1 by several fixing bolts 26. Two connecting blocks 27 are respectively installed on the front and rear sides of the substrate 25. Several snap-fit ​​components are respectively set at the front end of the two connecting blocks 27. One end of the four first connecting brackets 28 is connected to the upper and lower sides of the two connecting blocks 27 respectively. The other end of the four first connecting brackets 28 is connected to the inner walls of the upper and lower sides of the upper wall panel 1 respectively. One end of the four second connecting brackets 29 is connected to the left and right sides of the two connecting blocks 27 respectively. The four second connecting brackets 29 are connected to the inner walls of the left and right sides of the upper wall panel 1 respectively. Both ends of several reinforcing rods 30 are connected to one side of the four first connecting brackets 28 and the four second connecting brackets 29 respectively. In the specific implementation process, the upper wall panel 1 and the lower wall panel 2 adopt a frame shear wall. The two ends of the base plate 25 are connected to the inner walls on both sides of the upper wall panel 1 by several fixing bolts 26. Several reinforcing ribs 34 are used to increase the overall strength of the base plate 25. In use, the four first connecting frames 28 and the four second connecting frames 29 are set as a triangle, and the two together with the inner wall of the upper wall panel 1 form a stable triangle. Thus, the two work together to increase the overall strength of the upper wall panel 1. When the shear wall is affected by external forces, it can absorb the impact force, so that the wall has a good and high-strength seismic resistance effect. Several reinforcing rods 30 can increase the overall strength of the first connecting frames 28 and the second connecting frames 29. Several snap-fit ​​components can quickly limit the connection between the connecting block 27 and the cross reinforcing plate 36. The cross reinforcing plate 36 can further increase the seismic strength of the wall.

[0030] According to the instruction manual Figure 1-9 It can be seen that among the several snap-fit ​​components, one consists of a T-shaped slide 31, a sliding seat 32, and a fixed ear seat 33, and their connection and positional relationships are as follows: T-shaped groove 31 is formed at the front end of connecting block 27, the bottom of sliding seat 32 is slidably connected to T-shaped groove 31, fixed ear seat 33 is installed on the rear side of sliding seat 32, and fixed ear seat 33 is connected to T-shaped groove 31 by bolts and nuts. In the specific implementation process, after connecting the cross reinforcing plate 36 to the connecting block 27 and the front and rear ends of the upper wall plate 1 with bolts, the operator can slide the sliding seat 32 and the fixing ear seat 33 along the T-shaped slide groove 31, and make the triangular block 35 fit tightly against the corner of the cross reinforcing plate 36. Then, the operator tightens the bolts and nuts, thereby fixing the sliding seat 32 with the fixing ear seat 33. The four sliding seats 32 cooperate to limit and fix the cross reinforcing plate 36, thereby increasing the strength of the connection between the cross reinforcing plate 36 and the upper wall plate 1 and the connection, and thus increasing the seismic strength of the wall.

[0031] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
