Description

Technical Field

[0001] The present invention relates to the field of building walls, and more particularly to an integrated welding-free steel plate shear wall structure. Background Art

[0002] Shear walls are mainly divided into two types: concrete shear walls and steel plate shear walls. Concrete shear walls have the dual functions of bearing vertical gravity loads and lateral horizontal loads (such as wind and earthquake effects). They are common lateral force-resisting components in building structures, while steel plate shear walls focus on bearing lateral horizontal forces. Their advantage lies in the excellent ductility and energy dissipation characteristics of steel. When encountering a strong earthquake, the steel plate can effectively absorb seismic energy through plastic deformation. Therefore, its seismic performance is significantly better than that of concrete shear walls. It is especially suitable for heavy steel structure buildings with strict seismic requirements.

[0003] Existing steel plate shear walls have two major shortcomings: first, on-site installation requires assembly and welding, which makes the construction process relatively complicated; second, their ability to resist vertical loads is weak, which restricts their widespread application in multi-story buildings.

[0046] For details, please refer to Figure 2 and Figure 7 , the production process includes the following steps:

[0047] Step 1: Make the PCE outer frame 1: Weld the frame column 101 and the frame beam 102, and weld the bolt connection plate 103 on the inner side of the frame beam 102. Then, fill the abdominal cavity of the frame column 101 and the frame beam 102 with concrete to obtain the PCE outer frame 1.

[0048] Step 2: Make the steel plate shear wall body 2: Weld two end columns 4 and two T-shaped connecting plates 5 around the corrugated steel plate 3, then weld the end plate 6 to the upper end of the end column 4, and then fill the abdominal cavity of the end column 4 with concrete to obtain the steel plate shear wall body 2;

[0049] Step three, splicing; hoist the steel plate shear wall body 2 into the PCE outer frame 1, and make the T-shaped connecting plate 5 face the bolt connecting plate 103, then connect and fix the T-shaped connecting plate 5 and the bolt connecting plate 103 through horizontal bolts 10, and finally fix the end plate 6 to the frame beam 102 through vertical bolts 9.

[0050] Compared with the traditional steel plate shear wall structure, the present invention realizes the bolt connection between the steel plate shear wall body 2 and the PCE outer frame 1 by means of T-shaped connecting plates 5 arranged on both sides of the steel plate shear wall body 2 and bolt connecting plates 103 arranged on the frame beam 102, replacing the traditional welding connection method, realizing the rapid assembly of the steel plate shear wall body 2 and the PCE outer frame 1, simplifying the construction steps, and at the same time, by prefabricating the steel plate shear wall body 2, replacing the traditional on-site assembly method of the steel plate shear wall, further improving the installation efficiency of the shear wall structure, and cooperating with the vertical bolts 9 to bolt the end plate 6 and the frame beam 102 to improve the connection stability of the steel plate shear wall body 2 and the PCE outer frame 1; in addition, by adopting the end column 4 made of H-shaped steel, the vertical load bearing capacity of the steel plate shear wall body 2 is improved, overcoming the problem of insufficient vertical load capacity of the traditional steel plate shear wall.

[0051] See also Figure 6 and Figure 7 A first internal reinforcement 104 is embedded in the first precast concrete block 107, and the first internal reinforcement 104 is welded and fixed to the inner wall of the abdominal cavity of the frame column 101 and the frame beam 102; a second internal reinforcement 401 is embedded in the second precast concrete block 402, and the second internal reinforcement 401 is welded and fixed to the inner wall of the abdominal cavity of the end column 4.

[0052] Specifically, the pre-buried first internal ribs 104 improve the structural stability and integrity of the PCE outer frame 1 , and the pre-buried second internal ribs 401 improve the connection stability and integrity between the second precast concrete block 402 and the end column 4 .

[0053] See also Figure 5 and Figure 7 The end plate 6 is provided with evenly distributed plate end bolt holes 601, and the frame beam 102 is provided with vertical bolt holes 108 arranged opposite to the plate end bolt holes 601. The vertical bolts 9 pass through the vertical bolt holes 108 and the plate end bolt holes 601 in sequence to lock and fix the end plate 6 and the frame beam 102. The four corners of the end plate 6 are provided with rounded surfaces 602.

[0054] Specifically, vertical bolts 9 are used to improve the stability of the connection between the end column 4 and the frame beam 102. When the end column 4 bears a vertical load, the horizontal offset of the end column 4 is reduced, and the bearing capacity of the vertical load is improved. At the same time, when the corrugated steel plate 3 undergoes horizontal deformation, the bearing capacity of the end column 4 against horizontal shear force is improved; by setting the rounded surfaces 602 at the four corners of the end plate 6, during hoisting, a pair of end plates 6 slide into both sides of the bolt connection plate 103, thereby improving the positioning efficiency of the steel plate shear wall body 2 and the PCE outer frame 1 during installation, and improving the installation efficiency.

[0055] See also Figure 6 and Figure 7 A hand hole 105 is provided at a position opposite to the frame beam 102 and the end plate 6, and a vertical bolt hole 108 is connected to the hand hole 105. A plurality of equally spaced reinforcing ribs 106 are fixedly connected to the hand hole 105 located at the lower end frame beam 102, and the vertical bolt holes 108 and the reinforcing ribs 106 are spaced apart.

[0056] Specifically, the vertical bolts 9 are screwed through the hand holes 105 , and at the same time, the vertical bearing capacity of the frame beam 102 and the end column 4 is further improved by the reinforcing ribs 106 provided in the lower end frame beam 102 .

[0057] See also Figure 5 A cross reinforcement plate 8 distributed at both ends of the abdominal cavity is welded and fixed in the abdominal cavity of the end column 4, and a plurality of boot plates 7 are welded and fixed around the end column 4, and the boot plates 7 are welded and fixed to the end plates 6.

[0058] Specifically, the stability and load-bearing capacity of the connection between the end column 4 and the end plate 6 are enhanced by the cross reinforcement plate 8 and the boot plate 7. At the same time, a pair of cross reinforcement plates 8 are used to enclose the abdominal cavity of the end column 4 to form an enclosed filling cavity, which is convenient for concrete filling and reduces the impact of the filling concrete on the plate end bolt hole 601.

[0059] See also Figures 8-13In another embodiment of the present invention, a quick connection assembly is installed at the connection between the T-shaped connecting plate 5 and the bolt connecting plate 103. The quick connection assembly includes an inner connecting plate 11 abutting the outer end surface of the T-shaped connecting plate 5 and an outer connecting plate 12 abutting the outer end surface of the bolt connecting plate 103. The outer connecting plate 12 is fixedly connected with a plurality of threaded caps 13 distributed linearly and equidistantly. The horizontal bolts 10 sequentially penetrate the inner connecting plate 11, the T-shaped connecting plate 5, the bolt connecting plate 103 and the outer connecting plate 12 and are threadedly connected with the threaded caps 13. The outer connecting plate 12 is fixedly connected with a plurality of plug-in columns 14 spaced apart from the threaded caps 13. The inner connecting plate 11 is fixedly connected with a plug-in tube 15 that cooperates with the plug-in column 14. The plug-in tube 15 is slidably connected with an elastic pin 16 in the radial direction. The plug-in column 14 is provided with a positioning hole 1401 that cooperates with the elastic pin 16.

[0060] For details, please refer to Figure 9 and Figure 12 , the steps of connecting the T-shaped connecting plate 5 and the bolt connecting plate 103 include:

[0061] Step 1: Place the inner connecting plate 11 against the outside of the T-shaped connecting plate 5, then place the outer connecting plate 12 against the outside of the bolt connecting plate 103, and insert the plug-in column 14 into the plug-in cylinder 15;

[0062] Step 2: First, screw the horizontal bolt 10 at the center, and then screw the pair of horizontal bolts 10 that are symmetrical to the center.

[0063] Specifically, by means of the plug-in column 14 and the plug-in tube 15 spaced apart from the horizontal bolt 10, the T-shaped connecting plate 5 and the bolt connecting plate 103 can be quickly spliced ​​and connected before the horizontal bolt 10 is screwed, thereby reducing the probability of the steel plate shear wall body 2 being offset when the horizontal bolt 10 is screwed. After splicing, the horizontal bolt 10 is screwed to improve the stability of construction and the stability of the connection. In addition, by means of the elastic pin 16 provided on the plug-in tube 15, the plug-in column 14 and the plug-in tube 15 can be quickly connected, thereby reducing the number of horizontal bolts 10 and improving the installation efficiency of the steel plate shear wall body 2 and the PCE outer frame 1.

[0064] See also Figure 12 The inner connecting plate 11 includes a vertical portion and a horizontal portion. The vertical portion abuts against the side wall of the T-shaped connecting plate 5, and the horizontal portion is inserted into the gap between the T-shaped connecting plate 5 and the frame beam 102.

[0065] Specifically, the gap between the T-shaped connecting plate 5 and the frame beam 102 is filled by the inner connecting plate 11, and cooperates with the outer connecting plate 12 to further increase the load transfer area between the T-shaped connecting plate 5 and the frame beam 102, improve the vertical load bearing capacity, and improve the stability of the connection of the T-shaped connecting plate 5.

[0066] See also Figure 13 The front ends of the plug-in column 14 and the elastic pin 16 are conical, the cross-section of the positioning hole 1401 is stepped, and the elastic pin 16 abuts against a limit spring 17 fixedly connected to the plug-in tube 15. The longer the plug-in column 14 is inserted into the plug-in tube 15, the longer the length of the elastic pin 16 inserted into the positioning hole 1401.

[0067] Specifically, during the tightening process of the horizontal bolt 10, the longer the length of the plug-in column 14 inserted into the plug-in tube 15, the better the locking effect of the plug-in column 14, and it has a multi-stage locking function. At the same time, the threaded cap 13 is distributed on the outer connecting plate 12, and the plug-in tube 15 is distributed on the inner connecting plate 11. The locking directions of the horizontal bolt 10 and the plug-in column 14 are opposite, which improves the bolt connection effect of the steel plate shear wall body 2 and the PCE outer frame 1.
