Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and more specifically, to a steel plate composite shear wall splicing node. Background Technology

[0002] Steel plate composite shear wall is a new type of composite structural system. Its interior includes cavities formed by bending steel plates and ribs that separate the cavities. Other building materials can be selectively filled into the cavities as needed. It has the advantages of high load-bearing capacity, light weight, fast construction speed and good shear performance. It is especially suitable for high-rise and super high-rise buildings in high seismic zones and seismic reinforcement projects.

[0003] Patent CN222390700U discloses a splicing node for a steel plate composite shear wall, employing a bolted connection method instead of welding. Connection holes are pre-drilled in the I-beams and the steel plate shear wall structure, and then the splicing plates and connecting steel plates are assembled using bolts. However, this splicing node requires pre-cut slots on the corresponding connecting steel plates to match the reinforcing bars for different steel plate shear wall structures, enabling successful snap-fit ​​assembly. These slots must correspond to the specific steel plate shear wall structure to be usable. Therefore, it cannot be uniformly applied to steel plate shear walls with different intervals or numbers of reinforcing bars, resulting in poor versatility. Summary of the Invention

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a steel plate composite shear wall splicing node.

[0005] A steel plate composite shear wall splicing node includes corner fixing members arranged at the intersection of I-beams and I-beam foundation piles; a steel plate shear wall structure is arranged between two adjacent I-beams and two adjacent I-beam foundation piles, the steel plate shear wall structure includes a steel plate wall body, a frame arranged around the circumference of the steel plate wall body, and reinforcing bars arranged on the side of the steel plate wall body;

[0006] The corner fasteners are used to snap the frame body into place at the intersection of the I-beam crossbeam and the I-beam foundation pile;

[0007] It also includes a snap-fit ​​fitting for attaching the frame to the I-beam crossbeam.

[0008] Furthermore, the I-beams located above and below the steel plate shear wall structure have first through holes at both ends of their flange plates;

[0009] The I-beam foundation piles located on the left and right sides of the steel plate shear wall structure have second through holes in their flange plates;

[0010] The corner fastener is connected to the first and second through holes at the intersection of the I-beam and the I-beam foundation pile.

[0011] Furthermore, the corner fastener includes a horizontal fastener and a vertical fastener that are perpendicular to each other and integrally connected;

[0012] The horizontal fastener includes a horizontal C-shaped groove and a horizontal support plate integrally connected to the horizontal C-shaped groove. The horizontal C-shaped groove has a third through hole. The horizontal C-shaped groove is fastened to the end of the I-beam and fixed by bolts passing through the third through hole and the first through hole. The horizontal support plate extends to the bottom of the frame of the steel plate shear wall structure.

[0013] The vertical clamp includes a vertical C-shaped groove and a vertical support plate integrally connected to the vertical C-shaped groove. The vertical C-shaped groove has a fourth through hole. The vertical C-shaped groove is clamped at one of the second through holes of the I-beam foundation pile and is fixed by bolts passing through the fourth and second through holes. The vertical support plate extends to the side of the frame of the steel plate shear wall structure.

[0014] Furthermore, the flange plate of the I-beam is also provided with several fifth through holes, which are used to connect the snap-fit ​​component;

[0015] In the frame of the steel plate shear wall structure, a number of sixth through holes are provided in its horizontal section, and each of the sixth through holes coincides with the fifth through hole vertically.

[0016] Furthermore, the snap-fit ​​component includes a C-shaped groove structure with the opening facing horizontally. The snap-fit ​​component has a seventh through hole that runs vertically through the top and bottom. By using bolts to pass through the seventh through hole of the snap-fit ​​component, the fifth through hole of the I-beam beam, and the sixth through hole of the horizontal section of the frame, the frame of the steel plate shear wall structure and the I-beam beam can be fixed together.

[0017] Furthermore, it also includes auxiliary slots, with the snap-fit ​​component and the auxiliary slots located on both sides of the steel plate wall body; the snap-fit ​​component and the auxiliary slots intersect through the steel plate wall body.

[0018] Furthermore, the top and bottom of the steel plate wall body are respectively provided with several through holes for the fasteners and auxiliary slots to pass through.

[0019] Furthermore, the auxiliary slot is located on the same side as the corner fixing member.

[0020] Furthermore, the auxiliary slot is a C-shaped slot structure, with one wing extending into the through hole, and the wing having a vertical eighth through hole;

[0021] The snap-fit ​​component has a C-shaped groove structure, with its opening facing the opening direction of the auxiliary snap-fit ​​groove. One wing of the snap-fit ​​component extends into the through hole, and the snap-fit ​​component has a vertical ninth through hole. Bolts are used to pass through the ninth through hole of the snap-fit ​​component, the fifth through hole of the I-beam beam, and the eighth through hole of the auxiliary snap-fit ​​groove to fix the frame to the I-beam beam.

[0022] Furthermore, the eighth through hole is a waist-shaped hole, which can be adjusted according to the width of the flange of the I-beam crossbeam, thereby enabling adaptive clamping.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] Existing steel plate composite shear wall splicing nodes require pre-cutting of suitable slots in the connecting steel plates for different rib spacings or numbers, resulting in poor versatility. This new steel plate composite shear wall splicing node, through a combination of corner fasteners and snap-fit ​​components, only requires aligning the through holes and then bolting to achieve a secure connection between the steel plate shear wall structure and the I-beams and I-beam piles. It is independent of the specific layout of the ribs, therefore it is applicable to different rib spacings or numbers, exhibiting strong versatility.

[0025] Furthermore, a dual fixing method using corner fasteners and snap-fit ​​connectors is employed to securely connect the steel plate shear wall structure from both sides. This design not only enhances the connection strength but also ensures the overall stability of the structure through the snap-fit ​​effect of the corner fasteners.

[0026] Furthermore, an auxiliary slot is introduced to work in conjunction with the snap-fit ​​component. The eighth through hole of the auxiliary slot is a waist-shaped hole, which can be adjusted according to the width of the flange of the I-beam beam, thereby achieving adaptive snap-fit ​​clamping and enhancing the adaptability of the splicing node, enabling it to better cope with I-beams and steel plate shear wall structures of different specifications.

[0027] Furthermore, the snap-fit ​​connectors and auxiliary slots are located on both sides of the steel plate wall body, and can be fixed by bolts passing through the through holes. The auxiliary slots and snap-fit ​​connectors form a cross-through connection, which enhances the connection stability. In addition, the adaptive clamping effect of the auxiliary slots improves the shear resistance and overall stability of the structure. Attached Figure Description

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0050] like Figures 1-8 As shown, this embodiment provides a steel plate composite shear wall splicing node, including corner fixing members 3 arranged at the intersection of I-beam beam 1 and I-beam pile 2; a steel plate shear wall structure 4 is arranged between two adjacent I-beam beams 1 and two adjacent I-beam piles 2, the steel plate shear wall structure 4 including a steel plate wall body 41, a frame 42 arranged around the circumference of the steel plate wall body 41, and reinforcing bars 43 arranged on the side of the steel plate wall body. The corner fixing members 3 are used to snap the frame 42 to the intersection of the I-beam beam 1 and the I-beam pile 2; it also includes snap-fit ​​members 5 for snapping the frame 42 onto the I-beam beam 1.

[0051] In this embodiment, the I-beams 1 located above and below the steel plate shear wall structure 4 have first through holes 11 at both ends of their flange plates; the I-beam foundation piles 2 located on the left and right sides of the steel plate shear wall structure 4 have several second through holes 21 in their flange plates. Corner fasteners 3 connect the first through holes 11 and the second through holes 21 at the intersection of the I-beams 1 and the I-beam foundation piles 2.

[0052] Specifically, such as Figures 6-7 As shown, the corner fastener 3 includes a horizontal fastener and a vertical fastener that are perpendicular to each other and integrally connected; the horizontal fastener includes a horizontal C-shaped groove 31 and a horizontal support plate 32 integrally connected to the horizontal C-shaped groove 31. The horizontal C-shaped groove 31 has a third through hole 311. The horizontal C-shaped groove 31 is fastened to the end of the I-beam beam 1 and is fixed by bolts passing through the third through hole 311 and the first through hole 11; the horizontal support plate 32 extends to the bottom of the frame 42 of the steel plate shear wall structure 4.

[0053] The vertical fastener includes a vertical C-shaped groove 33 and a vertical support plate 34 integrally connected to the vertical C-shaped groove 33. The vertical C-shaped groove 33 has a fourth through hole 331. The vertical C-shaped groove 33 is engaged at one of the second through holes 21 of the I-beam pile 2 and is fixed by bolts passing through the fourth through hole 331 and the second through hole 21. The vertical support plate 34 extends to the side of the frame 42 of the steel plate shear wall structure 4. The corner fasteners 3 are pre-fixed to the second through holes 21 at appropriate positions on the I-beam pile 2, forming corner fasteners 3 at the four corners of the steel plate shear wall structure 4. During splicing, the four right-angled corners of the frame 42 of the steel plate shear wall structure 4 are embedded into the corner fasteners 3.

[0054] In this embodiment, the flange plate of the I-beam beam 1 is also provided with several fifth through holes 12, which are used to connect the snap-fit ​​parts 5. Correspondingly, in the frame 42 of the steel plate shear wall structure 4, several sixth through holes 421 are provided in its horizontal section, and each sixth through hole 421 overlaps with each fifth through hole 12 vertically. Since the corner fasteners 3 and snap-fit ​​parts 5 are fixed on both sides of the steel plate shear wall structure 4, the first through hole 11 used to connect the corner fasteners 3 and the fifth through hole 12 used to connect the snap-fit ​​parts 5 are located on both sides of the web of the I-beam beam 1.

[0055] To be more specific, such as Figure 8 As shown, the snap-fit ​​component 5 includes a C-shaped groove structure with its opening facing horizontally. The snap-fit ​​component 5 has a seventh through hole 51 that extends vertically. Bolts are used to pass through the seventh through hole 51 of the snap-fit ​​component 5, the fifth through hole 12 of the I-beam beam 1, and the sixth through hole 421 of the horizontal section of the frame 42, thus fixing the frame of the steel plate shear wall structure 4 to the I-beam beam 1. In this embodiment, the snap-fit ​​component 5 has two flanges of equal length.

[0056] The steel plate composite shear wall splicing node provided in this embodiment pre-fixes corner fasteners 3 to the second through holes 21 at appropriate positions on the I-beam foundation piles 2, forming corner fasteners 3 arranged at the four corners of the steel plate shear wall structure 4. During splicing, the four right-angled corners of the frame 42 of the steel plate shear wall structure 4 are embedded into the corner fasteners 3. At this time, the four corner fasteners 3 are located on the same side of the steel plate shear wall structure 4. Then, on the other side of the steel plate shear wall structure 4, the frame 42 and the I-beam beam 1 are fixed using snap-fit ​​fasteners 5, that is, bolts are used to pass through the seventh through hole 51 of the snap-fit ​​fastener 5, the fifth through hole 12 of the I-beam beam 1, and the sixth through hole 421 of the horizontal section of the frame 42, which can realize the fixation of the frame of the steel plate shear wall structure 4 and the I-beam beam 1. Thus, by combining the four corner fixing parts 3 and several snap-fit ​​parts 5 arranged on the other side, a firm connection is achieved between the steel plate shear wall structure 4 and the I-beam beam 1 and the I-beam foundation pile 2.

[0057] The steel plate composite shear wall splicing node provided in this embodiment only requires aligning the seventh through hole 51 of the snap-fit ​​part 5, the fifth through hole 12 of the I-beam beam 1 and the sixth through hole 421 of the horizontal section of the frame 42, and then connecting them with bolts. It has strong versatility and high adaptability.

[0058] The steel plate composite shear wall splicing node provided in this embodiment pre-fixes corner fasteners 3 to the second through holes 21 at appropriate positions on the I-beam foundation piles 2, forming a layout of corner fasteners 3 at the four corners; using the corner fasteners 3 on one side of the steel plate shear wall structure 4 and the snap-fit ​​pieces 5 on the other side, the steel plate shear wall structure 4 is fixed on both sides, realizing the stable fixation of the steel plate shear wall structure 4 to the I-beam beam 1 and the I-beam foundation pile 2. First, the steel plate shear wall structure 4 is snapped into the corner fasteners 3 at the four corners, and then during the fixing process with the I-beam beam 1, it is only necessary to align the snap-fit ​​pieces 5 with the fifth through holes 12, and then bolts can be used for fixing.

[0059] Existing steel plate composite shear wall splicing nodes require pre-cutting appropriate slots in the connecting steel plates for different rib spacings or numbers, resulting in poor versatility. The steel plate composite shear wall splicing node provided in this embodiment, through a combination of corner fasteners 3 and snap-fit ​​connectors 5, only requires aligning the through holes and then bolting to achieve a secure connection between the steel plate shear wall structure and the I-beams and I-beam piles. It is independent of the specific layout of the ribs, therefore it can be applied to different rib spacings or numbers, exhibiting strong versatility.

[0060] The steel plate shear wall structure 4 is securely connected from both sides using a dual fixing method consisting of corner fasteners 3 and snap-fit ​​connectors 5. This design not only enhances the connection strength but also ensures the overall stability of the structure through the snap-fit ​​effect of the corner fasteners.

[0061] Example 2:

[0062] The difference between this and the steel plate composite shear wall splicing node provided in Embodiment 1 is that it also includes an auxiliary slot 6, such as... Figures 9-14 As shown, the snap-fit ​​5 and the auxiliary snap-fit ​​6 are located on both sides of the steel plate wall body 41; the snap-fit ​​5 and the auxiliary snap-fit ​​6 cross each other through the steel plate wall body 41.

[0063] In this embodiment, as Figure 11 As shown, the top and bottom of the steel plate wall body 41 are respectively provided with several through holes 411 for passing through the snap-fit ​​piece 5 and the auxiliary snap-fit ​​groove 6. The auxiliary snap-fit ​​groove 5 is located on the same side as the corner fixing piece 3.

[0064] More specifically, in this embodiment, the snap-fit ​​component 5 has a C-shaped groove structure, with its opening direction facing the opening direction of the auxiliary snap-fit ​​groove 6; its two wings are of different lengths, one wing being longer and the other shorter. The longer wing of the snap-fit ​​component 5 extends into the through hole 411. The snap-fit ​​component 5 has a vertical ninth through hole 52, which passes through both wings.

[0065] The auxiliary slot 6 has a C-shaped structure with two wings of different lengths, one longer and the other shorter. The longer wing extends into the through hole 411 and has a vertical eighth through hole 61. The eighth through hole 61 is a waist-shaped hole that can be adjusted according to the width of the flange of the I-beam beam 1 to achieve a suitable clamping and holding.

[0066] In this embodiment, when the steel plate shear wall structure is connected to the I-beam beam 1, bolts are used to pass through the ninth through hole 52 of the snap-fit ​​5, the fifth through hole 12 of the I-beam beam 1, and the eighth through hole 61 of the auxiliary slot 6 to fix the frame to the I-beam beam 1.

[0067] The steel plate composite shear wall splicing node provided in this embodiment further introduces an auxiliary slot 6, which is used in conjunction with the snap-fit ​​component 5. The eighth through hole 61 of the auxiliary slot 6 is a waist-shaped hole, which can be adjusted according to the width of the flange of the I-beam beam 1, thereby achieving adaptive snap-fit ​​clamping and enhancing the adaptability of the splicing node, enabling it to better cope with I-beams and steel plate shear wall structures of different specifications.

[0068] The snap-fit ​​connector 5 and the auxiliary snap-fit ​​groove 6 are located on both sides of the steel plate wall body 41, and can be fixed by bolts passing through the through holes. The auxiliary snap-fit ​​groove 6 and the snap-fit ​​connector 5 form a cross-through connection, which enhances the connection stability. Furthermore, the adaptable clamping effect of the auxiliary snap-fit ​​groove 6 further improves the shear resistance and overall stability of the structure.

[0069] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
