Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and specifically to an anchored combined rigid steel plate wall column structure. Background Technology

[0002] In long-span or high-rise building structures, the core tube often bears huge horizontal and vertical loads, playing a key role in the stability and seismic resistance of the structure.

[0003] In super high-rise or large-span buildings, to meet the requirements of high load-bearing capacity, the core tube increasingly adopts composite shear walls with built-in steel plates. At the same time, stiff steel columns are set at the corners and ends of the shear walls to improve both the vertical load-bearing capacity and the horizontal shear resistance of the core tube.

[0004] Therefore, this utility model proposes an anchored combined rigid steel plate wall column structure. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the prior art and provide an anchored combined rigid steel plate wall column structure to solve the problem that the core tube in existing super high-rise or large-span buildings has insufficient vertical bearing capacity and horizontal shear resistance.

[0006] The technical solution to achieve the above objectives is:

[0007] This utility model provides an anchored combined rigid steel plate wall column structure, including:

[0008] Two spaced steel columns are fixed to a concrete base slab.

[0009] A steel plate wall is installed between the two steel columns;

[0010] A concealed beam, horizontally positioned between the two steel columns, connects to the steel plate wall.

[0011] Vertical stiffening ribs and horizontal stiffening ribs provided on one side of the steel plate wall; and

[0012] A shear key is embedded in the concrete base slab at the lower end, and the shear key is located at the lower end of the steel plate wall.

[0013] Furthermore, there are at least two vertical stiffening ribs and two horizontal stiffening ribs that are spliced ​​together. The end of the vertical stiffening rib is connected to the hidden beam, and the end of the horizontal stiffening rib is connected to the end of the steel column.

[0014] Furthermore, it also includes an anchor plate fixed to the lower end of the steel column and at least four anchor bolts passing through the anchor plate, the lower ends of which are anchored to the concrete base plate.

[0015] Furthermore, the height of this hidden beam is consistent with that of the corresponding floor slab.

[0016] Furthermore, the shear key is a mesh structure formed by splicing multiple steel structures together.

[0017] Furthermore, the steel column and the hidden beam are made of I-beams.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] By setting shear keys at the lower end of the steel plate wall and embedding them in the concrete base slab, the overall shear resistance of the steel plate wall is increased, thereby improving its seismic performance.

[0020] By fixing vertical and horizontal stiffening ribs to the steel plate wall, the overall structural strength of the steel plate wall is improved. Simultaneously, the steel columns are anchored to the concrete base slab, combining the advantages of both steel columns and steel plate walls. This enhances both the vertical load-bearing capacity and horizontal shear resistance of the core tube. Furthermore, the modular fabrication and installation of each component reduces the difficulty of installing the steel plate wall and steel columns. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] See Figure 1 This utility model provides an anchored composite stiffened steel plate wall column structure, solving the problem that the core tube in existing super high-rise or large-span buildings lacks sufficient vertical bearing capacity and horizontal shear resistance. By setting shear keys at the lower end of the steel plate wall and embedding them in the concrete base slab, the overall shear resistance of the steel plate wall is increased, thereby improving its seismic performance.

[0026] By fixing vertical and horizontal stiffening ribs to the steel plate wall, the overall structural strength of the steel plate wall is improved. Simultaneously, the steel columns are anchored to the concrete base slab, combining the advantages of both steel columns and steel plate walls. This enhances both the vertical load-bearing capacity and horizontal shear resistance of the core tube. Furthermore, the modular fabrication and installation of each component reduces the difficulty of installing the steel plate wall and steel columns.

[0027] The following description, in conjunction with the accompanying drawings, illustrates an anchored combined rigid steel plate wall column structure of this utility model.

[0028] See Figure 1 This illustrates the anchored combined stiffened steel plate wall column structure of this utility model. (See also...) Figure 2 This image shows a partial structural schematic diagram of the anchored combined stiffened steel plate wall column structure of this utility model. The following is a combination of... Figure 1 and Figure 2 This invention describes an anchored combined rigid steel plate wall column structure.

[0029] like Figure 1 and Figure 2 As shown, this utility model discloses an anchored combined stiffened steel plate wall column structure, comprising:

[0030] Two spaced steel columns 1 are fixed to a concrete base slab.

[0031] A steel plate wall 5 is installed between the two steel columns 1;

[0032] A concealed beam 2, horizontally positioned between the two steel columns 1, is connected to the steel plate wall 5;

[0033] Vertical stiffening ribs 3 and horizontal stiffening ribs 4 are provided on one side of the steel plate wall 5; and

[0034] A shear key 7 is embedded in the concrete base slab at its lower end, and the shear key 7 is located at the lower end of the steel plate wall 5.

[0035] Preferably, both sides of the steel column 1 are provided with vertical stiffening ribs 3 and horizontal stiffening ribs 4. By setting the vertical stiffening ribs 3 and the horizontal stiffening ribs 4, the structure of the steel plate wall 5 is made more stable, thereby ensuring the overall structural stability.

[0036] Specifically, the lower end of the shear key 7 is cast and embedded in the concrete base slab. The shear key 7 is connected to the structural reinforcement in the concrete base slab, allowing the stress of the steel plate wall 5 to be transferred to the concrete base slab through the shear key 7 and the structural reinforcement. This ensures the shear resistance of the steel plate wall 5, enabling the steel plate wall 5 and the entire building structure to withstand natural disasters such as earthquakes and typhoons, thus improving the safety of the main building. The ends of the steel plate wall 5 are welded to the steel column 1.

[0037] In one specific embodiment, there are at least two vertical stiffening ribs 3 and two horizontal stiffening ribs 4, which are spliced ​​together. The end of the vertical stiffening rib 3 is connected to the concealed beam 2, and the end of the horizontal stiffening rib 4 is connected to the end of the steel column 1. By splicing the vertical stiffening ribs 3 and the horizontal stiffening ribs 4, the structure formed by the splicing is stronger, and it is fixed to the steel plate wall 5, the concealed beam 2, and the steel column 1 by welding, thereby improving the structural strength of the steel plate wall 5. The connection between the horizontal stiffening ribs 4 and the vertical stiffening ribs 3 is fixed by welding, and the connection with the concealed beam 2 and the steel column 1 is also fixed by welding.

[0038] In one specific embodiment, it also includes an anchor plate 8 fixed to the lower end of the steel column 1 and at least four anchor bolts 6 passing through the anchor plate 8, the lower ends of the anchor bolts 6 being anchored to the concrete base plate.

[0039] In a preferred embodiment, the anchor plate 8 is welded and fixed to the steel column 1.

[0040] In another preferred embodiment, the anchor plate 8 is integrally formed with the steel column 1, thereby strengthening the connection between the two and making the steel column 1 more firmly fixed on the concrete base plate, preventing breakage and other situations.

[0041] In one specific implementation, the hidden beam 2 is at the same height as the corresponding floor slab.

[0042] In one specific embodiment, the shear key 7 is a mesh structure formed by splicing multiple steel structures together. By splicing the steel structures to form a mesh structure, the structural strength of the shear key 7 is improved. Then, the shear key 7 is embedded in the concrete base slab, thereby improving the shear resistance of the steel plate wall 5.

[0043] In a preferred embodiment, a slot is provided at the upper vertical steel structure of the shear key 7, and the lower end of the steel plate wall 5 is inserted into the slot. The slot facilitates the installation of the steel plate wall 5, as well as its positioning and connection. After the lower end of the steel plate wall 5 is inserted into the slot, it is fixed by welding.

[0044] In one specific embodiment, the steel column 1 and the hidden beam 2 are made of I-beams.

[0045] In a preferred embodiment, the steel column 1 can be made of cross steel, thereby further strengthening the structural strength of the steel column 1.

[0046] In a preferred embodiment, the height of the steel column 1 is the same as the design height of the core tube, and the height of the steel plate wall 5 is the same as the spacing between two adjacent floor slab structures. There are multiple steel plate walls 5 and hidden beams 2, and the steel plate walls 5 correspond to designated floors, while the hidden beams 2 correspond to designated floor slabs. The height of the multiple steel plate walls 5 and hidden beams 2 stacked together is the same as the height of the steel column 1, and the number of steel plate walls 5 provided is the same as the number of floors.

[0047] The construction process of an anchored combined rigid steel plate wall column structure according to this utility model will be described in detail below.

[0048] Before constructing the concrete base slab, the lower end of the shear key 7 is embedded in the designed position of the concrete base slab, and the structural reinforcement of the concrete base slab is tied together with the shear key 7 and fixed with angle steel frames. Then the concrete base slab is poured.

[0049] Install steel columns 1 at the designed location. First, move anchor plates 8 to the designed location, and then fix anchor plates 8 and steel columns 1 to the corresponding positions on the concrete base plate using anchor bolts 6. Then, install steel plate walls 5 between the two steel columns 1, weld the lower end of steel plate walls 5 to shear keys 7, adjust the verticality of steel plate walls 5, and then weld the end of steel plate walls 5 to steel columns 1.

[0050] Then, vertical stiffening ribs 3 and horizontal stiffening ribs 4 are welded to the side of the steel plate wall 5, and the ends of the horizontal stiffening ribs 4 are welded to the corresponding steel columns 1.

[0051] Install the hidden beam 2 at the designed location, weld and fix the end of the hidden beam 2 to the steel column 1, and weld and fix the upper end of the vertical stiffening rib 3 to the hidden beam 2.

[0052] Install steel plate wall 5 on the hidden beam 2, and weld the lower end of the steel plate wall 5 to the hidden beam 2 and weld the left and right ends to the steel column 1. Then repeat the above steps until the steel plate wall 5 reaches the designed height.

[0053] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
