Description

Technical Field

[0001] This utility model relates to the field of building structure engineering technology, and more specifically, to a modular splicing high load-bearing and earthquake-resistant steel structure load-bearing wall. Background Technology

[0002] Concrete walls are heavy, resulting in a large overall structural load and requiring high bearing capacity from the foundation, thus increasing project costs. Furthermore, the construction of concrete walls involves complex procedures such as formwork erection, rebar tying, concrete pouring, and curing, leading to a long construction period and impacting the overall project schedule. In contrast, steel load-bearing walls are load-bearing wall structures built using steel. Compared to traditional concrete or masonry walls, steel load-bearing walls are lighter, stronger, and have better seismic performance, making them suitable for various building types.

[0003] Although existing combined structural forms such as steel-supported steel plate shear walls and concealed steel plate shear walls still have poor seismic performance to a certain extent, and have problems such as insufficient energy dissipation capacity or low load-bearing seismic resistance.

[0004] Therefore, a modular, spliced, high-load-bearing, earthquake-resistant steel structure load-bearing wall is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a modular splicing high load-bearing and earthquake-resistant steel structure load-bearing wall to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular splicing high-load-bearing earthquake-resistant steel structure load-bearing wall, comprising high-strength end steel ribs, two sets of vertical stiffening ribs equally spaced between the two high-strength end steel ribs, the two sets of vertical stiffening ribs being laterally connected by three sets of first horizontal stiffening ribs, each set of vertical stiffening ribs being laterally connected by three sets of second horizontal stiffening ribs, the two sets of vertical stiffening ribs being interlaced and fixedly connected by inclined support stiffening ribs, an outer steel plate being provided on the outside of the high-strength end steel ribs, vertical stiffening ribs, first horizontal stiffening ribs, second horizontal stiffening ribs, and inclined support stiffening ribs, and an energy-dissipating filling material being poured into the outer steel plate.

[0007] Preferably, the high-strength end steel frame is bolted to the vertical stiffening rib, the vertical stiffening rib is bolted to the first horizontal stiffening rib and the second horizontal stiffening rib, and the vertical stiffening rib is bolted to the inclined support stiffening rib.

[0008] Preferably, each of the plurality of vertical stiffening ribs is fixedly connected to an upper shear connector at its top end, and each of the plurality of vertical stiffening ribs is fixedly connected to a lower shear connector at its bottom end.

[0009] Preferably, one end of the upper shear connector is fixedly inserted through the top of the outer steel plate, and one end of the lower shear connector is fixedly inserted through the bottom of the outer steel plate.

[0010] Preferably, the energy-dissipating filling material is a combination of high-strength concrete and steel plate energy-dissipating core material.

[0011] Preferably, the high-strength end steel frame includes a longitudinal end steel frame and a transverse end steel frame, with two transverse end steel frames symmetrically arranged between the two longitudinal end steel frames, and the longitudinal end steel frames and the transverse end steel frames are fixedly welded together.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] Compared to existing technologies, this modular, high-load-bearing, earthquake-resistant steel structure load-bearing wall improves the wall's plastic deformation capacity through the installation of vertical stiffeners, first horizontal stiffeners, second horizontal stiffeners, and inclined support stiffeners. Even under significant deformation, the wall is less prone to brittle failure, exhibiting excellent "earthquake-resistant" performance and providing a higher safety reserve. Furthermore, the energy-dissipating filling material within the outer steel plate enhances the overall strength and earthquake resistance of the wall. Finally, compared to concrete walls with equivalent load-bearing capacity, this invention, using a steel structure load-bearing wall, allows for factory prefabrication and on-site hoisting, reducing on-site construction work and improving efficiency. This multi-layered energy dissipation mechanism effectively absorbs and dissipates seismic input energy, protecting the safety of the main structure. Attached Figure Description

[0021] Embodiment 1

[0022] As shown in the attached Figures 1 to 5 A modular spliced high-load seismic steel structure load-bearing wall includes a high-strength end steel skeleton 1. Two groups of vertical stiffening ribs 2 are equidistantly arranged between the two high-strength end steel skeletons 1. The two groups of vertical stiffening ribs 2 are horizontally connected by three groups of first horizontal stiffening ribs 3, and each group of vertical stiffening ribs 2 is horizontally connected by three groups of second horizontal stiffening ribs 4. The two groups of vertical stiffening ribs 2 are cross-fixed and connected by inclined support stiffening ribs 5 arranged obliquely. An outer covering steel plate 9 is arranged outside the high-strength end steel skeleton 1, the vertical stiffening rib 2, the first horizontal stiffening rib 3, the second horizontal stiffening rib 4, and the inclined support stiffening rib 5. An energy-dissipating filling material 8 is poured inside the outer covering steel plate 9. The energy-dissipating filling material 8 adopts a combination of high-strength concrete and a steel plate energy-dissipating core material. It is composed of pre-cast high-strength concrete blocks, and during the pouring process, pre-processed thin steel strips are embedded inside the concrete blocks in a cross shape (such as "X" shape or "meter" shape). The ends of these cross steel strips are welded to the outer covering steel plate 9, the vertical stiffening rib 2, the first horizontal stiffening rib 3, the second horizontal stiffening rib 4, and the inclined support stiffening rib 5, ensuring effective shear force transmission between the energy-dissipating filling material 8 and the external steel frame.

[0023] The invention employs a multi-layered, closed grid-like reinforcing frame formed by vertical stiffeners 2, first horizontal stiffeners 3, second horizontal stiffeners 4, and inclined support stiffeners 5. This effectively constrains the internal filling material, preventing it from buckling under pressure and allowing it to share shear force. This enhances the wall's plastic deformation capacity, preventing brittle failure even under significant deformation and providing excellent earthquake resistance. Furthermore, the outer steel plate 9 contains energy-dissipating filling material 8, which improves the overall strength and seismic resistance of the wall. Compared to concrete walls with equivalent load-bearing capacity, this invention utilizes a steel structure load-bearing wall, allowing for factory prefabrication and on-site hoisting, reducing on-site construction work and increasing efficiency. This multi-layered energy-dissipating mechanism effectively absorbs and dissipates seismic input energy, protecting the main structure.

[0024] Example 2

[0025] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details:

[0026] In a preferred embodiment, the high-strength end steel frame 1 is bolted to the vertical stiffening rib 2, and the vertical stiffening rib 2 is bolted to the first horizontal stiffening rib 3 and the second horizontal stiffening rib 4. Finally, the vertical stiffening rib 2 is bolted to the inclined support stiffening rib 5. The bolted connection enables the modularization of the steel frame inside the wall, which facilitates transportation and handling.

[0027] In a preferred embodiment, an upper shear connector 6 is fixedly connected to the top of each of the multiple vertical stiffening ribs 2, and a lower shear connector 7 is fixedly connected to the bottom of each of the multiple vertical stiffening ribs 2. One end of the upper shear connector 6 is fixedly inserted through the top of the outer steel plate 9, and one end of the lower shear connector 7 is fixedly inserted through the bottom of the outer steel plate 9. By setting the upper shear connector 6 and the lower shear connector 7, the wall can be directly transported to the installation position, and then the upper shear connector 6 and the lower shear connector 7 can be directly set in the preset connection holes, which facilitates the subsequent construction and loading of the entire wall.

[0028] In a preferred embodiment, the high-strength end steel rib 1 includes longitudinal end steel rib 101 and transverse end steel rib 102, so that two transverse end steel ribs 102 are symmetrically arranged between the two longitudinal end steel ribs 101. The longitudinal end steel ribs 101 and the transverse end steel ribs 102 are fixedly welded together. The arrangement of the high-strength end steel rib 1 makes the entire wall have extremely high bending and compressive strength, while forming a steel frame protection function that fixes the vertical stiffening rib 2, the first horizontal stiffening rib 3, the second horizontal stiffening rib 4, and the inclined support stiffening rib 5.

[0029] The working process of this utility model is as follows: First, the vertical stiffening rib 2, the first horizontal stiffening rib 3, the second horizontal stiffening rib 4, and the inclined support stiffening rib 5 are fixedly connected together by bolts. Then, the arrangement of the vertical stiffening rib 2, the first horizontal stiffening rib 3, the second horizontal stiffening rib 4, and the inclined support stiffening rib 5 forms multiple closed grid-like reinforcing frames, which effectively constrain the internal filling material, prevent it from buckling under pressure, and jointly bear the shear force. This can improve the plastic deformation capacity of the wall, and the wall is not prone to brittle failure even under large deformation. It has excellent "no collapse under major earthquakes" performance and provides a higher safety reserve.

[0030] Meanwhile, the outer steel plate 9 is filled with energy-dissipating filling material 8, which can improve the overall strength and seismic resistance of the wall. Finally, compared with concrete walls of the same load-bearing capacity, the steel structure load-bearing wall of this invention can be directly prefabricated in the factory and hoisted on site, which reduces on-site construction work and improves efficiency. This multi-layered energy dissipation mechanism can effectively absorb and dissipate the energy input by earthquakes and protect the safety of the main structure. Finally, the setting of two high-strength end steel ribs 1 makes the entire wall have extremely high bending and compressive strength, while forming a steel frame that protects the vertical stiffening ribs 2, the first horizontal stiffening ribs 3, the second horizontal stiffening ribs 4, and the inclined support stiffening ribs 5. The above is the working principle of this modular splicing high load-bearing seismic steel structure load-bearing wall.
