Description

Anti-swing shock absorption protection method for adjacent buildings

Technical Field

The invention relates to the technical field of building earthquake resistance, in particular to an anti-swing shock absorption protection method for adjacent buildings.

Background

An earthquake-proof joint, also known as a quakeproof joint, is a structural joint designed between adjacent building units when a building is designed and built, and is a gap preset to reduce or prevent collision of the adjacent building structural units caused by earthquake action. In order to prevent the house from being damaged by earthquake, the house building is divided into a plurality of independent parts with simple shapes and uniform structural rigidity by using the shockproof joints.

However, after the earthquake-resistant joint divides the building into single building units, the horizontal area of each single building unit is small, the stability of each single building unit is poor, the swing-resistant effect is reduced, and especially for some high-rise buildings, the upper end of each single building unit can generate large swing vibration in some microminiature earthquakes and windy weather, so that the normal use of the building is greatly influenced. Meanwhile, when the building units are high in height, the single building unit is too large in swing amplitude, and collision between the adjacent building units is easily caused to cause damage.

To solve this problem, there are some prior art patents for shock absorbing devices to be installed between the anti-seismic seams. For example, CN201920488207.6 discloses a shockproof joint anti-collision device for building construction; CN201920880239.0 discloses an anti-collision device for quakeproof joints of building construction; CN201721077895.4 discloses a composite building anti-vibration joint device. The devices of these patented technologies can be installed between adjacent shock absorbing and shock resistant seams and are used to reduce the impact of an earthquake or hurricane on the swinging of the upper end of the building.

However, these prior patents also have the following drawbacks: all rely on the spring member who fixedly sets up about the horizontal direction to realize shock attenuation and buffering among 1 device, during the device was used, the spring is compressed and extension repeatedly at pressure and pulling force on the horizontal direction, its self also repeatedly, and the spring also can directly produce the reverse effort of bounce-back on the horizontal direction after atress compression and tensile self. Therefore, the acting force and the reacting force of the spring are converted back and forth in the horizontal direction, so that the actual damping effect of the device is poor, and the effect of reducing the left and right swinging of the building is poor. 2 the function effect of antidetonation seam self is the influence to adjacent building unit when avoiding single building unit to collapse and fall, and current antidetonation seam damping device's structure is fixed mounting between adjacent building, so when single building unit collapses and falls, can draw the effect through damping device and act on adjacent building unit, so greatly reduced the function effect and the meaning of antidetonation seam self.

Disclosure of Invention

Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows: how to provide a method for preventing vibration and shock absorption of adjacent buildings, which can realize shock absorption and shock absorption protection when the buildings swing left and right, can ensure the realization of self functions of earthquake-resistant joints and reduce the influence on the adjacent buildings when the buildings collapse.

In order to solve the technical problems, the invention adopts the following technical scheme:

the anti-swing shock absorption protection method for adjacent buildings is characterized in that a separation structure is arranged between bases at two ends of the shock absorption buffer device and building side walls on two sides of the shock absorption joint, so that when any side building collapses and falls down, the shock absorption buffer device can be separated from the building side walls by virtue of the separation structure.

Therefore, the invention can reduce the influence on the building by the arranged damping and buffering device when the building swings left and right in earthquake or hurricane weather. The separation mechanism that sets up simultaneously makes shock attenuation buffer can not influence the function of antidetonation seam self, when one side building collapses and falls promptly, can not pull and produce great influence to adjacent building through shock attenuation buffer. The self functional action and significance of the anti-seismic seam are ensured.

As an optimized option, the shock absorption and buffering device comprises two bases which are arranged on two building side walls on two adjacent sides of two adjacent buildings (namely two building side walls on two sides of a shock-resistant joint), and a horizontal shock absorption spring which is horizontally arranged is arranged between the two bases.

In this way, the quick release mechanism (i.e. release structure) is able to complete the separation between the building side wall and the apparatus when the building on one side collapses and falls. Therefore, the safety of the device can be greatly improved, and the influence of the installation and use of the device on the self function of the anti-seismic seam is avoided.

Furthermore, quick release mechanism includes the connection limit that outwards extends the formation along the both ends about the base trailing flank and lower extreme, still includes a base of fixing on the building lateral wall, and the base lateral surface is for being used for the installation face with the laminating of base trailing flank installation, still corresponds on the base lateral surface and connects the limit and be provided with the slot that the evagination constitutes, connect the limit and peg graft downwards and fix in the slot.

Thus, when the building on one side collapses and falls, the base falls along with the building and is separated from the base by the slot under the action of self weight. The collapse tendency of the building on the other side is aggravated by the fact that the collapsed building acts on the building on the other side through the device. Meanwhile, the quick release mechanism has the advantages of simple structure, reliable release and stable bearing force when not released.

Furthermore, two sides of the connecting edge and two sides of the corresponding slot are in an inverted splayed shape.

Therefore, the base can be conveniently inserted into the slot through the connecting edge, and the building can be conveniently and quickly separated when collapsed.

Furthermore, the outer side surface of the base is also provided with a layer of elastic material layer, and the outer side surface of the elastic material layer forms the mounting surface.

Like this, elastic material layer's setting can conveniently be connected the limit and insert better fastening behind the slot and fix, and self can produce certain elasticity shock attenuation energy dissipation effect simultaneously. Meanwhile, more separation spaces can be generated by means of elastic deformation of the elastic material layer during quick separation, and quick separation of the device is facilitated. Preferably, the elastic material is a rubber material. Has the advantages of low cost, convenient preparation, excellent elasticity, being beneficial to adjusting the elasticity and the like.

Furthermore, a row of fixing points are arranged at the lower end of the base, the fixing points are connected and fixed to the side wall of the building through screws, prying blocks correspondingly extend downwards below the fixing points, and the base and the prying blocks are made of hard materials.

Like this, when the base and the base of building one side of collapsing do not realize breaking away from, the building of collapsing passes through the base and the base of device drive opposite side and overturns downwards, through the leverage effect of sled piece, can prize the screw more fast reliably, realizes breaking away from. Play the dual fail-safe effect like this, can guarantee under the various condition when one side building collapses, the homoenergetic accomplishes the separation of device and building fast.

Furthermore, the base at the fixing point is arranged convexly, so that a horizontal distance is reserved between the fixing point base and the building side wall.

When one side building collapses downwards like this, can be favorable to more the sled piece to exert leverage effect, can pry the breaking away from of screw realization device better.

Therefore, after the device is used, when the building units swing in the process of earthquake or hurricane, two adjacent building units swing towards the mutual away direction, the sliding rod slides in the sliding cylinder and pulls the horizontal damping spring to be in a stretching state, the swinging distance is reduced by means of the tension of the horizontal damping spring, and meanwhile, the horizontal damping spring deforms in a telescopic mode to convert part of kinetic energy into internal energy to be released. When adjacent building unit toward the direction swing of drawing close each other, the slide bar slides and compresses horizontal damping spring in the slide cartridge, relies on horizontal damping spring's compression to realize the buffering shock attenuation, reduces the trend that adjacent building drawn close, and horizontal damping spring compression deformation turns into partial kinetic energy to internal energy release simultaneously. In the process, the horizontal damping spring is arranged in the sliding barrel, so that the spring can be protected, and the spring can be in contact friction with the inside of the sliding barrel when being compressed and deformed, so that kinetic energy can be better converted into internal energy and transmitted to the outside of the sliding barrel to be released; improve buffering shock attenuation effect.

As optimization, the two bases are installed at the upper end positions of the side walls of two adjacent buildings. Thus, the effect of preventing the upper end of the building from swinging can be better achieved.

Furthermore, the grooves are uniformly arranged along the circumferential direction, so that the contact stress between the grooves and the outer periphery of the spring is more balanced and stable.

Like this, lubricated liquid can also play lubricated effect to the spring simultaneously, avoids the card of spring to bet. This structure makes no matter the piston drives horizontal damping spring for compression state or tensile state's in-process, all can drive lubricating oil and flow each other in piston both sides through the liquid hole, relies on the flow of lubricated liquid to turn into internal energy with kinetic energy better to can rely on lubricated liquid to transmit the internal energy heat of conversion to each dissipation of device better, so can realize the buffering shock attenuation to the building better. When the piston rod is implemented, the lubricating liquid in the sliding cylinder is not filled and a section of space is reserved, so that the piston rod can be better inserted. In addition, if the inner wall of the sliding cylinder is provided with the groove, the function of the liquid passing hole can be realized by the groove without arranging the liquid passing hole on the piston. The groove is used for realizing the flowing of the lubricating oil, and the lubricating effect of the lubricating oil on the sliding of the piston in the sliding cylinder can be enhanced. Based on the optimized inner cavity structure of the horizontal damping spring, the invention also discloses a damping and energy-consuming method of the building anti-seismic joint damping device, namely, lubricating liquid is arranged in the inner cavity of the damping device for mounting the damping spring, and kinetic energy is better converted into internal energy and heat and is dissipated by depending on the flowing of the lubricating liquid; and can further rely on lubricated liquid to improve damping spring periphery lubricated effect for damping spring can be compressed under periphery and inner chamber wall contact state, converts kinetic energy into internal energy heat and dissipates through the friction of damping spring and inner chamber wall better.

When the device uses like this, when two bases kept away from each other, can drive two sliders through four-bar linkage along pole setting relative slip, compress two vertical damping spring, realize buffering shock attenuation energy dissipation. But the reaction of two vertical damping springs is along the vertical direction direct action on slider and slide cartridge to directly form the reaction along the horizontal direction, so can avoid the reaction of device to lead to the building to last horizontal hunting better. Although part of the reaction force can be transmitted to the base through the sliding block and the connecting rod, the kinetic energy can be further converted into the internal energy through the friction action of the middle sliding block and the vertical rod, and the reaction force effect is reduced. Meanwhile, the vertical damping springs and the horizontal damping springs are combined, so that a multidimensional three-dimensional buffering damping effect can be formed, and the effects of damping and energy dissipation can be better achieved.

Like this, when vertical damping spring is driven to slide cartridge one end by the slider and compresses tightly, can compress tightly the friction disc at the slide cartridge surface, improve the frictional damping coefficient of relative motion between slide cartridge and the friction disc for slide cartridge can convert kinetic energy into internal energy better when sliding in the friction disc. The horizontal motion shock attenuation of component and vertical motion shock attenuation can realize the correlation among the device like this, can improve the three-dimensional shock attenuation energy dissipation effect of device better. And meanwhile, the friction plate can improve the support stability of the vertical damping spring.

Like this, when device both sides building unit horizontal hunting, can be through the screw-thread fit of sleeve and screw rod, convert the axial motion of horizontal direction into the rotation of sleeve or screw rod, through the friction of internal thread and external screw thread with kinetic energy conversion interior energy consumption and dissipate. Wherein the inclination of the thread inclined plane of the external thread and the internal thread is larger than the friction angle, so that the thread matching component can better rotate when being subjected to axial force, and the phenomenon that the thread can not rotate due to self-locking is avoided. Therefore, the device realizes buffering and shock absorption by means of friction damping, and cannot generate the reaction effect of driving the building to continuously swing left and right along the horizontal direction. Can be more favorable to preventing the building horizontal hunting, improve the shock attenuation buffering effect. Simultaneously, the quick separation mechanism who sets up can accomplish the separation between building lateral wall and the device when one side building collapses and falls.

When adjacent building unit toward the direction swing of drawing close each other, the slide bar slides and compresses horizontal damping spring in the slide cartridge, relies on horizontal damping spring's compression to realize the buffering shock attenuation, reduces the trend that adjacent building drawn close, and horizontal damping spring compression deformation turns into partial kinetic energy to internal energy release simultaneously. In the process, the horizontal damping spring is arranged in the sliding barrel, so that the spring can be protected, and the spring can be in contact friction with the inside of the sliding barrel when being compressed and deformed, so that kinetic energy can be better converted into internal energy and transmitted to the outside of the sliding barrel to be released; improve buffering shock attenuation effect.

Wherein, when in use, the two bases 2 are arranged at the upper end positions of the side walls of two adjacent buildings. Thus, the effect of preventing the upper end of the building from swinging can be better achieved.

Wherein, the horizontal damping spring 3 and the sliding barrel 4 are arranged along the same axial lead, and the outer side of the horizontal damping spring 3 is contacted with the inner wall of the sliding barrel before being compressed to the extreme position.

Like this, horizontal damping spring is spring external diameter can outwards expand a little when compressed for the spring outside and sliding barrel inner wall contact produce the friction and improve its frictional force, help better turn into the interior energy consumption with kinetic energy and scatter, avoid changing repeatedly between kinetic energy and the elastic potential energy and reduce actual shock attenuation effect. Simultaneously this structure makes and draws close each other between the adjacent building more, and the friction damping coefficient that horizontal damping spring week side and slide cartridge inner wall contact produced is bigger, can turn into internal energy with kinetic energy more, so can be favorable to more assisting to avoid building upper end to bump.

Wherein, the inner wall of the slide cylinder 4 is provided with a groove 6 along the length direction.

Like this, the recess supplies horizontal damping spring to receive the extrusion shrink back, can reserve the space that supplies the spring outside expansion to warp at the slide cartridge inner wall when spring periphery and slide cartridge inner wall contact, avoids the spring to be blocked and dies, guarantees that the spring can kick-back smoothly. Furthermore, the grooves are uniformly arranged along the circumferential direction, so that the contact stress between the grooves and the outer periphery of the spring is more balanced and stable.

Like this, lubricated liquid can also play lubricated effect to the spring simultaneously, avoids the card of spring to bet. This structure makes no matter the piston drives horizontal damping spring for compression state or tensile state's in-process, all can drive lubricating oil and flow each other in piston both sides through the liquid hole, relies on the flow of lubricated liquid to turn into internal energy with kinetic energy better to can rely on lubricated liquid to transmit the internal energy heat of conversion to each dissipation of device better, so can realize the buffering shock attenuation to the building better. When the piston rod is implemented, the lubricating liquid in the sliding cylinder is not filled and a section of space is reserved, so that the piston rod can be better inserted. In addition, if the inner wall of the sliding cylinder is provided with the groove, the function of the liquid passing hole can be realized by the groove without arranging the liquid passing hole on the piston. The groove is used for realizing the flowing of the lubricating oil, and the lubricating effect of the lubricating oil on the sliding of the piston in the sliding cylinder can be enhanced. Based on the inner cavity structure of the horizontal damping spring, the invention also discloses a damping and energy-consuming method of the building anti-seismic joint damping device, namely, lubricating liquid is arranged in the inner cavity of the damping device for mounting the damping spring, and kinetic energy is better converted into internal energy and heat and is dissipated by depending on the flowing of the lubricating liquid; and can further rely on lubricated liquid to improve damping spring periphery lubricated effect for damping spring can be compressed under periphery and inner chamber wall contact state, converts kinetic energy into internal energy heat and dissipates through the friction of damping spring and inner chamber wall better.

Wherein, the ends of the sliding cylinder 4 and the sliding rod 5 are arranged on the base 2 by a spherical hinge 9.

Thus, a floating space can be left for the vibration of the building in the up, down, left and right directions.

The damping device is characterized by further comprising a vertical damping spring 10 which is vertically arranged, and the base 2 is in transmission connection with the vertical damping spring 10 through a connecting rod 11 which is obliquely arranged. The transmission connection means that when the upper end of the building swings left and right, the base can drive the vertical damping spring to compress or extend through the connecting rod.

Like this, after having add vertical damping spring, when the device both sides building unit horizontal hunting, can drive vertical damping spring through the connecting rod and compress or stretch out along vertical direction, turn into vertical damping spring elastic potential energy with kinetic energy and further turn into the interior energy consumption and scatter, realize buffering shock attenuation energy dissipation. Simultaneously because vertical damping spring's reaction force is direct to vertical direction, can directly not produce and drive the building along the horizontal direction and last the reaction effect of horizontal hunting. Can be more favorable to preventing the building horizontal hunting, improve the shock attenuation buffering effect.

The damping device comprises a vertical rod 12 which is vertically arranged, a sliding barrel through hole for a sliding barrel 4 to penetrate is formed in the middle of the vertical rod 12, a sliding block 13 is sleeved on the upper portion and the lower portion of the vertical rod 12 in a vertically sliding mode, vertical damping springs 10 are installed on the portions, located between the sliding block 13 and the sliding barrel 4, of the upper portion and the lower portion of the vertical rod 12 in a sleeved mode, a connecting rod 11 and the sliding block 13 are arranged on two bases in the vertical direction respectively and connected, and the two ends of the connecting rod 11 are hinged to the bases and the sliding block respectively to form a parallelogram four-bar mechanism.
