Description
Technical field
The utility model relates to a kind of building unit.More particularly, the utility model relates to a kind of hydraulic shock-absorption member that is used for the building frame structure.
Background technology
China is the multiple country of earthquake, and various places have all run into the ruinous earthquake of high earthquake magnitude in recent years, and the people's safety of life and property has all been produced huge infringement, especially the higher school of densely populated degree has been brought immeasurable loss.In addition, along with the continuous improvement of fast growth of national economy and living standards of the people, people improve day by day to safety, the reliability requirement of building structure under geological process.The reason that causes existing building can not satisfy current social demand mainly contains following two kinds: (1) Anti-quake Architectural Structure Design, under the condition of considering economy and scientific level, designing and calculating is carried out in seismic fortification intensity, the design basic acceleration of earthquake and design earthquake grouping according to each department, and it is not enough to some extent that the great rarely occurred earthquake of destructiveness is set up defences; (2) ability of building structure opposing earthquake, the effect of mainly directly resisting seismic forces by the structural element self-bearing capacity, and plastic failure very easily takes place even collapses in its structure under the aftershock effect.
The existing energy-dissipating and shock-absorbing design of China is that energy dissipator is set in building structure, provides additional damping by its local distortion, to consume the seismic energy of input superstructure, reaches the shockproof requirement of expection.Such as the shock insulation layer of being made up of parts such as rubber earthquake isolation support and dampers being set in the bottom, house, with natural vibration period, the increase damping that prolongs the total system, reduce the seismic energy of input superstructure, reach the shockproof requirement of expection.Frame construction is to use form of structure very widely in China's engineering, although shock insulation and energy-dissipating tech have suitable advantage aspect the anti-seismic performance that improves structure, but because aspect such as economic, practical, these technology are used seldom in frame construction.
The utility model content

The specific embodiment
With reference to the accompanying drawings, below utility model is described in detail.
Fig. 1 is the exploded view of hydraulic shock-absorption member.
Be equipped with sealing plate structure 10 in another pit, sealing plated construction 10 has the base plate and the round pie loam cake of the hollow cylindrical of upper end open bottom lock; Have one to be the outside that 8, one spring housings 7 of vertical shift block that circular columnar bottom possesses flange are located at the cylindrical-shaped structure of vertical shift block 8 in the sealing plate structure; Spring 7 and vertical shift block 8 are by loam cake and the airtight sealing of base plate, and the base plate bottom communicates with residing pit by an oil duct system.
Wherein, the main effect of base 1 is a loading liquid oil, transmits oil pressure, supports and fix other body element; The effect of union 2 is to irritate liquid water in balance weight 3; Balance weight 3 is positioned at the circular hole of sliding shoe 6, owing to constituted seal chamber between sealing ring 4, gland 5 and the sliding shoe 6, based on the relative theory of air bottle type accumulator, the impact force that is subjected to is converted into hydraulic pressure and air pressure, thereby reaches the effect of storage power.When impact force disappears, thereby release hydraulic pressure and air pressure release energy, and balance weight is also pushed back initial position by the liquid of fluid chamber.The afterbody of balance weight 3 (the inner) size is greater than head (outer end) size, pass prefabricated circular hole from the inside in the time of installation and be exposed, thereby having guaranteed that balance weight 3 can only inwardly compress restores to the original state then, can not de-orbit; The effect of sealing ring 4, gland 5 is cavitys of making a sealing.Spring 7 mainly act as the well-distributed pressure that transmits by self-deformation self-balancing vertical shift block 8; Vertical shift block 8 passes to spring equably with the pressure that oil duct produces; The main effect of sliding supporting structure 9 is to drive sliding shoe 6 with moved further and sliding path that horizontal direction is provided for sliding shoe 6 by moving up and down of self; Sealing plate structure 10 effects are that spring 7 and vertical shift block 8 are sealed in the base 1.
The assembly unit process of this member is specific as follows: (1) pours into liquid oils in base 1 left side pit, in this pit of again sliding supporting structure 9 being packed into; Sliding supporting structure 9 is pressed into liquid oils and is full of the cavity that whole left and right sides pit surrounds; (2) balance weight 3 is installed in the sliding shoe 6, sealing ring 4, gland 5 are fixed in the sliding shoe 6, in the sliding supporting structure 9 of again sliding shoe 6 being packed into; (3) spring 7 is placed on the vertical shift block 8, vertical shift block 8 is packed in the sealing plate structure 10, with after sealing plate structure 10 and base 1 welding, forms seal chamber again.(4) after the installation, in sliding supporting structure 9, add liquid water.
The course of work of this member is as follows: when not having seismic force effects, whole system is in illustrated equipoise, and sliding shoe 6 is because action of gravity is in centre of form place, sliding supporting structure 9 bottom surface.After earthquake caused additional horizontal force, floor drove sliding shoe 6 and produce horizontal movement in sliding supporting structure 9, thereby impels seismic energy to subdue; If actual generation lateral seismic active force is bigger, then balance weight 3 starts, thus further loss of energy.After earthquake, sliding shoe 6 is because the center of sliding supporting structure 9 bottom surfaces is got back in action of gravity voluntarily.After earthquake causes vertical active force, floor and sliding shoe 6 impose on sliding supporting structure 9 with pressure, sliding supporting structure 9 compressions are loaded into the liquid oils in the base 1, liquid oils passes to vertical shift block 8 by oil duct with pressure, vertical shift block 8 passes to pressure spring 7 again, thereby with the pressure self-balancing.
Fig. 2 is the 3 d effect graph of hydraulic shock-absorption member, promptly is figure shown in Figure 2 among Fig. 1 after the component assembly unit; Fig. 3 has described concrete size of each ingredient of this member and arrangement.
Fig. 4 is the part figure of A-A in the hydraulic shock-absorption member orthogonal view, has described balance weight arrangement in the plane.
Fig. 5 is the drawing at C place in the hydraulic shock-absorption member orthogonal view, and Fig. 6 is the drawing at B place in the hydraulic shock-absorption member orthogonal view, and Fig. 5 and Fig. 6 have described the structure of oil duct and the flow direction of liquid oils.
Implementation process of the present utility model can be taked following concrete operations step:
(1) fixed hydraulic cushioning members: at first adopt the high-precision electronic measuring apparatus that the hydraulic shock-absorption member is positioned, reserve notch in the position of determining, beam and member link position distributing bar are encrypted, finishing the formwork of beam column afterwards builds, Deng beam column reach enough intensity after level equally spacedly the high-strength bolt on the hydraulic shock-absorption member is weldingly fixed in the concrete beam, guarantee that the horizontal error of hydraulic shock-absorption member is no more than 1%.
(2) concreting floor: according to the position of hydraulic shock-absorption member sliding shoe 6, anchoring high-strength bolt thereon, and high-strength bolt is connected with the slab muscle, wherein plate and member link position distributing bar are encrypted, set up template, finish concrete building, natural curing can reach instructions for use in 28 days.
At last, can be as required at hydraulic shock-absorption component surface sprayed fire proofing, corrosion protection layer to improve its endurance quality.
