Description
Technical field
The present invention relates to technical field of buildings, specifically building frame compression-member-free support anti-seismic structure and method for supporting.
Background technology
In the building structure aseismatic field, framework-braced structures is a kind of effective antidetonation system, can increase the lateral deformation stiffness of building structure, reduces the shearing and the moment of flexure of Vierendeel girder, post.The supporting rod of framework-braced structures generally is made up of shaped steel.It is a kind of extraordinary material that the shaped steel rod member bears pulling force, but when bearing pressure, itself exists bent problem of bending unstability.Because the reciprocating of seismic forces, the internal force of supporting rod will experience the process of pulling force and the continuous conversion of pressure, and under pressure, supporting rod is in case the bent unstability of bending is deactivated, and support system just can lose efficacy, and jeopardizes the safety of building.Therefore framework-braced structures is a kind of antidetonation system that remains to be improved.
Supporting rod in present known framework-braced structures, under seismic force effects all by not only bearing pulling force but also bear pressure design, the bearing capacity of rod member does not have problem under tension, in order to improve the rod member compression bearing, the cross section type of rod member is done some improvement, bend the unstability ability to improve the anti-song of rod member when the pressurized, support as anti-bent the bending of at present up-to-date nothing bonding.But supporting rod always should be born pulling force and bear pressure again, and material use efficient is not high, and cost is uneconomical, nor reliable.
If the supporting rod in framework-braced structures only produces pulling force and do not produce pressure under the reciprocating of seismic forces,, avoid the lateral deflection unstability just can give full play to the tension ability of steel.But supporting rod under the reciprocating of seismic forces always pulling force and pressure alternately occur, this is a pair of insoluble contradiction.
Summary of the invention
The objective of the invention is to overcome the problem and the difficulty of above-mentioned existence, a kind of tension bearing capacity and the energy-dissipating property that can give full play to steel is provided, reduce the shearing and the moment of flexure of Vierendeel girder, post, improve the building frame compression-member-free support anti-seismic structure and the method for supporting of Building Structural Safety.
Technical scheme of the present invention is: the compression-member-free support anti-seismic structure of building frame is that a pulling force lock is installed in every supporting rod.Method for supporting is: supporting rod is connected with the oblique hinge knot of levels bean column node, can be that crossbar supports, and also can be that the monocline bar supports.
The structure of pulling force lock is:
First kind of form: mainly form by piston rod (5-2), wedge block (5-3), pressing plate (5-5), spring (5-6), sealing ring (5-7), bolt (5-8), upper shell (5-9), the lower house (5-10) of connecting rod (5-1), band wedge; Lower house inside is wedge shape chute (5-4), piston rod (5-2) and wedge block (5-3) place in the wedge shape chute (5-4) and by pressing plate and fix, and spring places on the pressing plate, last lower house Bolt Connection, connecting rod and upper shell are connected as a single entity, and sealing ring is in the lower house bottom.
The supporting rod of building frame-braced structures links to each other with piston rod with the connecting rod of pulling force lock, the axle power of supporting rod passes to the pulling force lock by connecting rod and piston rod, when supporting rod bears pulling force, the trend of the oriented bottom offset of piston rod (among Fig. 2) of band wedge, but this moment, wedge block was in " wedging state " in the wedge shape chute, piston rod can not be to bottom offset, and this moment, the pulling force lock transmitted the pulling force of supporting rod; When having pressure, supporting rod does the time spent, the piston rod of band wedge moves up, supporting rod is in " sliding mode ", there is not pressure in the rod member, produce the gap when piston rod moves up simultaneously and between the wedge block, spring and pressing plate are in impaction state all the time, and spring and pressing plate promotion wedge block move downward along the wedge shape chute this gap is filled up, and are in all the time between piston rod, wedge block, the lower house three " wedging state ".When the seismic forces reciprocating, when supporting rod changed tension into by pressurized, the pulling force lock still transmitted the pulling force of supporting rod.
Therefore, this pulling force lock can reach the pulling force of reliable delivery supporting rod, and does not transmit the purpose of pressure.
Second kind of form: mainly form by slide block (6-4), upper limit plate (6-5), lower limiting board (6-6), spring (6-7), sealing ring (6-8), connecting bolt (6-9), housing (6-10), chute (6-11), the bolt (6-12) of connecting rod (6-1), the piston rod (6-2) of being with alligator, alligator (6-3), band alligator; Connecting rod and upper shell are connected as a single entity, the piston rod of band alligator cooperates with the slide block of band alligator, the slide block of band alligator is made up of the semicylinder of two symmetries, the slide block of band alligator has the upper limit plate on it, it has limiting plate down, and places in the lower house, and spring is pressed on the both sides of the slide block of being with alligator by bolt, four springs of every side, connect to go up lower house with bolt, sealing ring is in the bottom of lower house, chute (6-11) the upper limit plate and under have in the limiting plate.
Supporting rod in the building frame links to each other with piston rod 2 with the connecting rod 1 of pulling force lock, the slide block of band alligator can radially uphold in chute and close up, the piston rod of band alligator and the relative (see figure 10) of alligator disc of the slide block contact position of being with alligator with the inclined-plane, can unidirectionally slide backward hold.The axle power of supporting rod passes to the pulling force lock by connecting rod and piston rod, when supporting rod bears pulling force, the piston rod of band alligator and interlaced the blocking of alligator of the slide block contact position of being with alligator, can not be along radially upholding, lower limiting board stops the piston rod and the slide block of band alligator to move vertically, and this moment, the pulling force lock transmitted the pulling force of supporting rod; Do the time spent when supporting rod has pressure, the piston rod of band alligator moves up, because the obstruction of limiting plate, the slide block of band alligator can not move axially, and can only radially open along chute, and piston rod can move vertically, supporting rod is in " sliding mode ", does not have pressure in the rod member.The spring that is compressed by bolt promotes to be with the slide block of alligator to close up along the chute radial contraction simultaneously, makes interlaced again the blocking of alligator of piston rod and slide block contact position.When the seismic forces reciprocating, when supporting rod changed tension into by pressurized, the pulling force lock still transmitted the pulling force of supporting rod.
Therefore, second kind of pulling force lock can reach equally and only transmit the rod member pulling force, do not transmit the purpose of pressure.
Above-mentioned described pulling force lock is the key device of implementing in building frame compression-member-free support anti-seismic structure and the method for supporting.
As shown in Figure 1, framework-braced structures is under the situation that meets with horizontal seismic force F reciprocating, when seismic forces is to do the time spent from left to right, in the supporting rod 3 and 4 that intersects, because they are different with the angle of seismic force effects direction, supporting rod 3 bears pulling force, and supporting rod 4 bears pressure; And when seismic forces is to do the time spent from right to left, supporting rod 3 and 4 stressed just in time opposite, supporting rod 3 bears pressure, supporting rod 4 bears pulling force.As previously mentioned, the shaped steel rod member bears the easy lateral deflection unstability of pressure, and bearing capacity is very low, but the bearing capacity that bears pulling force is very high.After the shaped steel rod member pressurized unstability, support system just loses the usefulness of opposing horizontal earthquake, and then the destruction that causes building structure.
Used technology of the present invention, framework-braced structures is under the situation that meets with the horizontal earthquake reciprocating, when seismic forces is to do the time spent from left to right, in the supporting rod 3 and 4, originally supporting rod 3 bears pulling force, and supporting rod 4 bears pressure, owing in supporting rod 3 and 4, be connected the pulling force lock, supporting rod 4 is in sliding mode, and actual do not have pressure, and supporting rod 3 is bearing pulling force; When seismic forces is to do the time spent from right to left, supporting rod 3 and 4 stressed wanting oppositely, the pulling force lock that was in originally in the supporting rod 4 of sliding mode plays a role, and makes supporting rod 4 produce pulling force, bears geological process; And the supporting rod 3 of bearing left-hand geological process pulling force originally will produce pressure, and the pulling force lock in the supporting rod 3 plays a role at this moment, and supporting rod 3 is in sliding mode, is not stressed.That is to say, and though horizontal earthquake action from a left side or from the right side, must have one in the supporting rod 3 and 4 is tension member, and another root does not stress, and so, just can avoid the problem of the pressurized unstability of supporting rod, when seismic design, can calculate geological process by single diagonal in tension.
Building frame compression-member-free support anti-seismic structure of the present invention and method for supporting are a kind of brand-new, innovative building structure aseismatic methods, owing to have only tension member in the supporting rod, there is not compression member, therefore can give full play to the tension bearing capacity and the energy-dissipating property of steel, avoid supporting rod pressurized unstability, the characteristic that has kept simultaneously framework-braced structures system again, the lateral deformation stiffness and the energy-dissipating property of building structure have been increased, reduce the shearing and the moment of flexure of Vierendeel girder, post, reduce construction costs, improve the safety of building structure.Pulling force locking utensil of the present invention has stressed clear and definite, and mechanism is simple, and is easily manufactured, is easy to installation and maintenance, the characteristics of good endurance.
Building frame compression-member-free support anti-seismic structure of the present invention and method for supporting can be used for the building of multilayer, high-rise concrete structure and steel work, also can be used in the seismic hardening improvement project.
