Shockproof hydraulic device
(57) Abstract:The invention relates to absorbing the impact force of the hydraulic devices and used in buildings and structures in the zone of earthquakes. In reinforced concrete structures of cylindrical or rectangular shape concreted steel spherical chamber with an annular hollow swirl or Luggage in the form of two steel coupled between a spherical communicating vessels with pipes and tubes for filling liquid and control the liquid level. A large part of the volume chambers filled with liquid, and the rest is air. A powerful impetus through hard shell Foundation supports and the camera will report a significant acceleration of the fluid. Liquid, counteracting the impact, go with a very large acceleration in the direction of the kick. The liquid, having a negligible compressibility, all the energy, like a piston variable forms, will be sent to the compression and rarefaction zones of air, creating a vortex flow in the fluid. This will be facilitated by a sufficient fluidity of the liquid and the spherical shape of the camera. Thus the increase durability and efficiency shockproof hydraulic devices. 2 C.p. f-crystals, 7 Il. Izopet and Foundation blocks.The closest technical solution is shockproof hydraulic unit comprising equipped with a nozzle for filling a liquid sealed chamber shaped like a ball or spherical paired chamber in the form of two communicating vessels.The disadvantage of this device is its lack of durability and efficiency.The objective of the invention is the improvement of the strength and efficiency shockproof hydraulic device by reducing the destructive forces of earthquakes on buildings and structures.The problem is solved by the fact that resistant hydraulic unit comprising equipped with a nozzle for filling a liquid sealed chamber spherical shape or paired chamber spherical shape in the form of two communicating vessels, made in the form of monolithic reinforced concrete structures, in which concreted Luggage made with swirl.In addition, the swirl can be performed as part of a chamber filled with air; the camera can be made with metal housing and nozzle to control the liquid level.In Fig. 1 shows popery. 2 - the same, with dual camera spherical shape with an annular swirler of Fig. 3 is a transverse section of the steel housing of the camera; Fig. 4 - plan for possible locations of the cameras of Fig. 5 - section a-a in Fig. 4; Fig. 6 and 7 are diagrams of flow of fluid from the shock of the earthquake.In Fig. 1 shows a hydraulic shock device 1, which consists of monolithic reinforced concrete structures 2, for example, the Foundation supports, in which concreted steel hermetic chamber 3 spherical shape with a pipe 4 to fill it with liquid 5 and tube 6. Support 2 may have a cylindrical or rectangular shape. The chamber 3 has an annular swirl 7, located in the upper part of the chamber 2, is free from liquid 5. Camera 2 is also equipped with a pipe 8 with the sealing tube 9 on the thread, which is used to control the liquid level 5.In Fig. 2 presents shock hydraulic device 10 formed from a monolithic concrete structure 11, for example, the Foundation supports mainly cylindrical or rectangular shape with concreted in her tight steel chamber 12. The camera 12 has a spherical shape in the form of two coaxial La liquid level 5 in the chamber 12 with the tube 9 and swirler 15, located in the upper part of the chamber 12, is free from liquid 5.The swirler 7, 15 is formed with a cone-shaped protrusions 16, 17 respectively of the chambers 3, 12, serving to create a vortex flow of the liquid 5, which received a boost from the shock of the earthquake.In Fig. 4 shows the device 18 with an approximate plan for placement of multiple cameras 12 to the concreting of the reinforced concrete structure 19 that is used as, for example, a support or plate.The camera 12 is installed with a gap 20 from the base 21 supports or plates and after filling them with liquid 5 fasten the cargo to prevent their ascent in the solution of concrete. Foundation support mounted on shock-absorbing layer 22, for example, of sheet rubber or rubber crumb placed on the sealing layer of crushed stone 23.The device 1, 10 is as follows.The blow to the camera 3, 12 create an air-liquid emulsion with a large number of bubbles, which in the conditions of constant changes of speed and direction of flows will be compressed and decompressed, acting as springs and absorbing the force of impact. These two factors are the basis of the ideas of this invention. This liquid 5 should imathia eddy flow at impact is easily seen in Fig. 6, 7. Assuming that the strongest earthquake destroys mainly primarily based on building its lower part, while the horizontal oscillations together with the fall of the complete destruction of the elemental relationships of the entire building, it is for this reason necessary shockproof device 1, 10, able to absorb longitudinal and transverse vibrations, to concentrate in a base Foundation of building opposition to seismic effects.At the instant a powerful impetus to the liquid acts on the principle of a moving body of variable form, creating a zone of pressure and vacuum, but the camera creates change their direction of flow, absorbing the force of the push. The air provides the freedom to develop fluid flows, acting as a spring.It is very important that the specific weight of the fluid mass in the support was high, i.e., Foundation support should be lightweight, but also durable. Such support will be used in the construction of strip foundations, as an intermediate support between the grillage and pile on the construction of bridges defined by rows and filled with reinforced concrete pillars will become a reliable Foundation pad for the installation of heavy and complicated which najednou pipe for filling a liquid sealed chamber spherical shape or paired chamber spherical shape in the form of two communicating vessels, characterized in that the device is a monolithic reinforced concrete structures, in which concreted Luggage made with swirl.2. The device under item 1, characterized in that the swirl is made as part of a chamber filled with air.3. The device according to p. 2, characterized in that the camera is made with a metal casing and nozzle to control the liquid level.
FIELD: building, particularly for erecting pile-plate foundations for industrial buildings and structures, for instance for main buildings of heat power plants.
SUBSTANCE: method involves arranging drilled cast-in-place pile, grouting plate grillage and installing antivibration mounts. Anchorage reinforcement is placed in pile heads and arranged along marked building axes. Anchorage reinforcement is then grouted and resilient antivibration mounts are installed at pile heads. Resilient antivibration mounts are fixed in plane on anchorage reinforcement with the use of fasteners so that antivibration mounts may perform restricted movement. Installed on antivibration mounts is rigid metal foundation frame of upper building in which anchoring reinforcement for securing skeleton of building to be erected is installed. Reinforcement rods and supply lines are inserted in process orifices formed in foundation frame beams and frame is grouted to form panel grillage.
EFFECT: reduced work content, increased simplicity and speed of bearing grillage frame erection; improved building stability.
