Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of building engineering, and particularly relates to a shock-absorbing layer structure between a foundation and a building. BACKGROUND

[0002] After an earthquake, the degree of damage to the structure determines the ability of the structure to defend against disasters. The structure itself has the ability to resist natural disasters and is a safe haven for humans, but the ability of the structure to resist natural disasters is limited. Current science and technology is not yet sufficient to accurately predict the occurrence of earthquakes, so the focus of engineering seismic research is on how to effectively enhance the seismic resistance of the structure. In the prior art, the traditional seismic method is usually used, which uses the structure itself to accept the energy of the vibration and then causes the structure to be damaged, so as to achieve the purpose of consuming the energy input into the structure. By using this seismic method, the components of the structure will be severely damaged after an earthquake, and even the building may directly collapse. Moreover, while blindly increasing the stiffness of the structure and the strength of the material, the cross section of the building is increased, and the usable area of the building is greatly reduced, causing waste of building materials and a sharp increase in the construction cost of the building. In order to overcome the shortcomings of the traditional seismic method, some scholars have proposed the concept of structural vibration control. The goal of structural vibration control is to make the response values of the structure under the action of external force meet the limited values of the national requirements for engineering structures. Structural vibration control is to control the response values of the structure under the action of external force by some means. Under the action of external force, the structure moves, and when the energy dissipation device is arranged, the structure will move together with the additional energy dissipation device. The working principle of structural vibration control is to arrange dampers or other devices with energy dissipation effect at the displacement position of the building. The additional energy dissipation device will cause the friction of the rod with a friction surface or the extrusion of the internal viscous fluid when it moves, and energy conversion will occur in this process, so that kinetic energy is converted into other forms of energy, thereby consuming the energy of the vibration, and ultimately achieving the purpose of consuming the energy of the vibration by the structure to protect the building.

[0003] In the prior art, such as Chinese patent CN216108656U, a seismic-resistant structure for a construction engineering foundation is disclosed, comprising a shock-absorbing box, a damping plate installed on the shock-absorbing box, a first damping block fixedly connected to the damping plate, a second damping block fixedly connected inside the shock-absorbing box, a telescopic spring installed inside the shock-absorbing box, one end of the telescopic spring fixedly connected to the first damping block, and the other end of the telescopic spring fixedly connected to the second damping block, a sliding groove provided in the shock-absorbing box, a support plate fixedly connected to the damping plate, and the support plate slidably connected inside the shock-absorbing box. When the foundation of this utility model is subjected to vibration, the first damping block, the second damping block, the elastic arc plate, and the telescopic spring are used to alleviate the vibration force exerted on the foundation, preventing the vibration force from being too large and causing displacement of the building structure. However, this utility model can only alleviate the longitudinal waves of the earthquake, and cannot alleviate the horizontal shaking caused by the transverse waves. Another example is Chinese patent CN210342008U, which discloses a shock-absorbing foundation structure, including a foundation beam, a connecting bracket, a shock-absorbing layer, a base layer and a damping shock absorber. The lower end of the foundation beam is fixedly connected to the upper end of the connecting bracket, the lower end of the connecting bracket is connected to the upper end of the shock-absorbing layer, the lower end of the shock-absorbing layer is fixedly connected to the upper end of the base layer, and the damping shock absorber is provided on opposite sides of the connecting bracket. One end of the damping shock absorber is hinged to the side of the connecting bracket through a connecting member A, and the other end is hinged to the base layer through a connecting member B. The damping shock absorbers are all inclined from bottom to top toward the direction close to the connecting bracket. The shock-absorbing foundation structure provided by this utility model can reduce the impact of earthquakes on superstructures and improve the safety of superstructures. However, this utility model only installs damping shock absorbers between the foundation layer and the foundation beam. Although it can achieve the effect of shock absorption on the building to a certain extent, the multiple dampers are independent of each other, and the overall support effect and overall stability of the building are poor. At the same time, it also has certain limitations in terms of shock absorption and vibration reduction of the building. Summary of the Invention

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

[0019] 1. The present invention provides a shock-absorbing layer structure between a foundation and a building.

The elastic column cooperates with the upper high-strength elastic ring and the lower high-strength elastic ring to convert part of the kinetic energy into heat energy and prevent displacement between the upper end plate and the lower end plate, thereby further consuming the vibration between the support column and the foundation base, thereby ensuring the stability of the building.

Two corresponding connecting blocks in two damping structures are connected by connecting bolts, thereby realizing auxiliary connection between multiple damping structures, making the connection and disassembly between multiple damping structures more convenient, and providing convenience for construction; and the connecting block is connected to the rotating steel ring. When vibration occurs, relative movement occurs between the damping structures, and the rotating steel ring can adapt to this movement, thereby avoiding the phenomenon of disassembly of the damping structure during vibration, and improving the stability of the damping structure.

[0021] 3.

[0024] 6. The present invention provides a shock-absorbing layer structure between the foundation and the building. When the foundation base moves due to vibration, the guide outer cylinder and the guide inner cylinder in the auxiliary structure cooperate to guide the displacement of the vibrating foundation base, thereby preventing the foundation base from excessive displacement due to vibration. At the same time, the foundation base rubs against the guide outer cylinder and the guide inner cylinder, and the vibration of the foundation base is consumed by friction, thereby having a shock-absorbing effect on the building.

[0025] 7. The present invention provides a shock-absorbing layer structure between the foundation and the building.

The upper dovetail plate 16 and the lower dovetail plate 17 are both provided with two through-openings 42. The transverse positioning pin shaft 18 is provided in the transverse positioning hole 41 that coincides with the through-opening 42.

[0045] like Figure 7 As shown in the figure, the vertical connecting assembly 49 further comprises upper connecting sleeves 19 and lower connecting sleeves 20, the upper connecting sleeves 19 are connected at the bottom end of the upper end plate 8, the lower connecting sleeves 20 are connected at the top end of the lower end plate 9, upper dovetail connecting strips 21 are arranged between two groups of vertically adjacent upper connecting sleeves 19, lower dovetail connecting strips 22 are arranged between two groups of vertically adjacent lower connecting sleeves 20, four vertical positioning holes 43 are arranged on the upper end plate 8 and the lower end plate 9, two vertical through holes 44 are arranged on the upper connecting sleeves 19, the lower connecting sleeves 20, the upper dovetail connecting strips 21 and the lower dovetail connecting strips 22, vertical positioning pins 23 are arranged in the vertical positioning holes 43 coinciding with the vertical through holes 44.

[0046] The horizontal connecting assembly 48 and the vertical connecting assembly 49 adopted by the present application can splice multiple damping mechanisms 47, improve the stability of the damping mechanism 47 as a whole, and in the process of vibration, the mutual connection between the multiple damping mechanisms 47 can significantly reduce the damage of vibration to the damping mechanism 47, and then the elastic column 11, the upper high-strength elastic ring 12 and the lower high-strength elastic ring 13 in the damping mechanism 47 cooperate with each other, utilize their characteristics to continuously convert part of kinetic energy from the support column 7 into internal energy, consume the vibration for the second time, and prevent the position deviation between the upper end plate 8 and the lower end plate 9, so as to ensure the stability of the damping mechanism 47, and then further consume the vibration between the support column 7 and the foundation base 10, thereby ensuring the stability of the building 1.

[0047] Further, as shown in the figure, Figure 4 The elastic column 11 is sleeved with the upper high-strength elastic ring 12 and the lower high-strength elastic ring 13, the top end of the upper high-strength elastic ring 12 is in contact with the upper end plate 8, and the bottom end of the lower high-strength elastic ring 13 is in contact with the lower end plate 9. The upper high-strength elastic ring 12 and the lower high-strength elastic ring 13 cooperate with each other to convert part of kinetic energy into heat energy, prevent the position deviation between the upper end plate 8 and the lower end plate 9, and further consume the vibration between the support column 7 and the foundation base 10, thereby ensuring the stability of the building 1.

[0048] Further, as shown in the figure, Figure 4 The upper high-strength elastic ring 12 and the lower high-strength elastic ring 13 are connected with a rotating steel ring 14, the connecting block 15 is connected to the side wall of the rotating steel ring 14, as shown in the figure, Figure 8As shown, the two corresponding connecting blocks 15 in two adjacent damping structures 47 are connected by a connecting bolt 45. By connecting the two corresponding connecting blocks 15 in the two damping structures 47 through the connecting bolt 45, auxiliary connection between multiple damping structures 47 can be achieved, making the connection and disassembly between multiple damping structures 47 more convenient, providing convenience for construction; and the connecting block 15 is connected to the rotating steel ring 14. When vibration occurs, relative movement occurs between the damping structures 47. The rotating steel ring 14 can adapt to this movement, avoiding the disassembly of the damping structure 47 during the vibration process, and improving the stability of the damping structure 47.

[0049] Further, such as Figure 6 As shown, the upper end plate 8 is provided with four upper circular holes 37, and the lower end plate 9 is provided with four lower circular holes 38. Figure 3 As shown, an upper embedded rod 30 that matches the foundation base 10 is disposed in the upper circular hole 37, and a lower embedded rod 31 that matches the cement 6 is disposed in the lower circular hole 38. Anti-slip rings 32 are connected to both the upper embedded rod 30 and the lower embedded rod 31. By connecting the upper embedded rod 30 and the lower embedded rod 31 to the foundation base 10 and the cement 6, the connection between the damping structure 47 and the foundation base 10 and the cement 6 can be made more stable. Furthermore, the anti-slip rings 32 connected to the upper embedded rod 30 and the lower embedded rod 31 further improve the stability of the connection between the damping structure 47 and the foundation base 10.

[0050] Further, such as Figure 3 As shown, auxiliary bars 36 are connected to the horizontal positioning pin 18 and the vertical positioning pin 23 , which facilitates the installation and removal of the horizontal positioning pin 18 and the vertical positioning pin 23 .

[0051] Further, such as Figure 1 As shown, concrete 3, crushed gravel 4, fine sand 5 and mortar 6 are arranged in sequence from bottom to top in the cement foundation pit 2, and multiple support columns 7 pass through the concrete 3, crushed gravel 4, fine sand 5 and mortar 6 in sequence. The mortar 6 is connected to the bottom end of the lower end plate 9. The use of this layered foundation structure can absorb the vibration transmitted from the earth to the support columns 7 step by step, thereby improving the stability of the foundation, and can play a certain fixing role on the support columns 7, which has a preliminary shock-absorbing effect on the building 1.

[0052] Further, such as Figure 1 As shown, an auxiliary structure is installed between the cement foundation pit 2 and the foundation base 10, such as Figure 9 As shown, the auxiliary structure includes a guide outer cylinder 24 and a guide inner cylinder 25. The guide outer cylinder 24 is connected to the side wall of the basic base 10, and the guide outer cylinder 25 is connected to the cement foundation pit 2. Figure 10As shown, the guide inner cylinder 25 is arranged inside the guide outer cylinder 24, and a petal opening is opened on the guide inner cylinder 25; when the basic base 10 moves due to vibration, the guide outer cylinder 24 and the guide inner cylinder 25 in the auxiliary structure cooperate to guide the displacement of the vibrating basic base 10, thereby preventing the basic base 10 from excessively deflecting due to vibration. At the same time, the basic base 10 rubs against the guide outer cylinder 24 and the guide inner cylinder 25, and the vibration of the basic base 10 is consumed by friction, thereby playing a shock-absorbing role for the building 1.

[0053] Further, such as Figure 1 As shown, a shielding structure is installed between the cement foundation pit 2 and the foundation base 10. The shielding structure includes two horizontal shielding plates 26 and two vertical shielding plates 27. The horizontal shielding plates 26 and the vertical shielding plates 27 are both arranged at the top of the cement foundation pit 2. Figure 11 As shown, the bottom end of the horizontal shielding plate 26 is connected to a horizontal bar 28, as shown in FIG. Figure 12 As shown, the bottom end of the vertical shielding plate 27 is connected to the vertical bar 29, the foundation base 10 is provided with a mounting ring groove 46, the horizontal bar 28 and the vertical bar 29 are both arranged in the mounting ring groove 46, and the side wall of the building 1 is connected to the folding protective plate 34, and the bottom end of the folding protective plate 34 is in contact with the horizontal shielding plate 26 and the vertical shielding plate 27; the shielding structure can prevent external debris from entering the gap between the cement foundation pit 2 and the foundation base 10, and can prevent the shock-absorbing layer structure from reducing or failing in its shock-absorbing effect on the building 1, thereby improving the stability and reliability of the shock-absorbing layer mechanism.

[0054] Further, such as Figure 1 As shown, multiple anchor rods 33 are set on the side wall of the cement foundation pit 2 and penetrate into the ground. The multiple anchor rods 33 are all made of threaded steel, which makes the connection between the cement foundation pit 2 and the ground more stable, thereby ensuring the stability of the building 1.

[0055] Further, such as Figure 1 As shown, a plurality of drainage holes 35 are provided on both the left and right sides of the cement foundation pit 2 to facilitate drainage of water in the cement foundation pit 2 .

[0056] In summary, the working process of the shock-absorbing layer structure between the foundation and the building is as follows: after the construction of the building 1 is completed, when the ground vibrates, the vibration is transmitted to the cement foundation pit 2 and drives the cement foundation pit 2 to vibrate, and the cement foundation pit 2 transmits the vibration to the support column 7 and drives the support column 7 to vibrate. The concrete 3, crushed sand and gravel 4, fine sand 5 and mortar 6 in the cement foundation pit 2 absorb the vibration of the support column 7 to achieve the purpose of primary shock absorption. Then, the support column 7 transmits the vibration to the damping structure. The elastic column 11, the upper high-strength elastic ring 12 and the lower high-strength elastic ring 1 in the damping structure 3 utilizes its characteristics to convert the kinetic energy of vibration into internal energy, and consumes the vibration for the second time. Finally, the damping structure transfers the consumed vibration energy to the foundation base 10. The foundation base 10 moves due to the vibration. The guide outer cylinder 24 connected to the side wall of the foundation base 10 cooperates with the guide outer cylinder 24 connected to the cement foundation pit 2 to guide the displacement of the vibrating foundation base 10, thereby preventing the foundation base 10 from excessively deflecting due to the vibration. At the same time, the vibration of the foundation base 10 is finally consumed by friction, thereby playing a shock-absorbing role for the building 1.

[0057] The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
