Description
Technical field
The present invention relates to building engineering field, relate in particular to a kind of single-rail antidetonation damping single-direction balls steel support that is applied to bridge.
Background technology
As shown in Figure 1, existing ball shaped steel bearing mainly comprises a upper bracket plate 1, an intermediate panel 2 and a undersetting plate 4 three big parts, has generally also had the tetrafluoro plate 3,5 of carrying effect between three parts.Because said structure is generally vertical stacked, therefore whole bearing has good load-carrying properties and certain displacement function.
For satisfying the needs of normal operating conditions such as expanding with heat and contract with cold, general above-mentioned bearing vertical bridge to direction across bridge on all be reserved with certain clearance.The non-constant of the anti-shear performance of above-mentioned bearing, particularly when being subjected to the huge external force of direction across bridge (as under situations such as violent earthquake) are easy to the phenomenon that causes beam or fall frame, cause serious economy loss but also therefore.
And along with the reinforcement of the antidetonation consciousness of taking precautions against natural calamities, the designer generally more biases toward and consider shockproof factor in existing structure design now.
Therefore, those skilled in the art is devoted to develop a kind of bearing with the anti-fall beam ability of antidetonation.
Summary of the invention
Because the above-mentioned defective of prior art, technical problem to be solved by this invention provides a kind of single-rail antidetonation damping single-direction balls steel support with the anti-fall beam ability of good antidetonation.
For achieving the above object, the invention provides a kind of single-rail antidetonation damping single-direction balls steel support, comprise at least: a upper bracket plate, described upper bracket plate has the semi-sphere type bottom surface; One end basin is provided with the intermediate panel between basin of the described end and the described upper bracket plate, and described intermediate panel has the semi-sphere type end face that cooperates with described upper bracket plate; One undersetting plate, described lower support plate have baseplane and carrying upper surface, and basin of the described end is arranged on the described carrying upper surface; Comprise that also two are symmetricly set on the speed lock on the described lower support plate, the cylinder barrel of described speed lock is fixedlyed connected with basin of the described end, and the piston rod of described speed lock is fixedlyed connected with described lower support plate; Also comprise a guide rail, described guide rail is arranged between basin of the described end and the described lower support plate, is provided with in the same way with described speed lock.
Preferably, described speed lock has adjustable damping value, the different lock speed value of the corresponding described speed lock of different damping values.
Preferably, be respectively arranged with wearing plate between described upper bracket plate and described intermediate panel, basin of the described end and the described lower support plate.
Bearing of the present invention has been symmetrical arranged 2 speed locks on lower support plate, the speed lock of utilization has the characteristic of translational speed lock value, when the relative sliding velocity of bearing during less than setting value, the speed lock can be free to slide, allow to produce relative motion between end basin and the lower support plate, whole bearing is the one-way type bearing under this state.When the relative sliding velocity of bearing during greater than setting value, the speed lock is locked and can not be free to slide, and does not allow to produce between end basin and the lower support plate relative motion, and whole bearing is a fixed bearing under this state.
Structure and principle thus, bearing of the present invention can be a conversion value with a movement velocity of setting, and changes between one-way support and fixed bearing, has had both advantages concurrently, thereby has compared with the bearing of prior art, has the anti-fall beam technique effect of better antidetonation.
Since the present invention also between end basin and lower support plate, with the speed lock be provided with a guide rail in the same way, make both between relatively move more smooth and easy.
Be described further below with reference to the technique effect of accompanying drawing, to understand purpose of the present invention, feature and effect fully design of the present invention, concrete structure and generation.
Description of drawings
Fig. 1 is the structural representation of a ball shaped steel bearing of the prior art;
Fig. 2 is the broken section structural representation of the present invention's one specific embodiment;
Fig. 3 is the plan structure schematic diagram of the present invention's one specific embodiment.
The specific embodiment
As Fig. 2, embodiment shown in Figure 3, single-rail antidetonation damping single-direction balls steel support of the present invention comprises at least: a upper bracket plate 2, one end basin 5, one undersetting plates 9.
Be provided with intermediate panel 4 between end basin 5 and the upper bracket plate 1.Intermediate panel 4 has the end face of the protruding spherical that is slidingly matched mutually with upper bracket plate 2, to provide bearing needed corner.
Be respectively arranged with the wearing plate 3,7 of modified ultra-high molecular weight polyethylene material between upper bracket plate 2 and intermediate panel 4, end basin 5 and the lower support plate 9,, reduce slip resistance in order to reduce slide coefficient.
Bearing of the present invention also comprises two speed locks 6 that are arranged on symmetrically on the lower support plate 9.The cylinder barrel 61 of speed lock 6 is fixedlyed connected with end basin 5, and the piston rod 62 of speed lock 6 is fixedlyed connected with lower support plate 9.
Bearing of the present invention also comprises a guide rail 8.Guide rail 8 is arranged between end basin 5 and the lower support plate 9, is provided with in the same way with speed lock 6.Guide rail 8 provides the guiding of relative slip between end basin 5 and the lower support plate 9, and transmits transverse load.
In use, when the relative sliding velocity of bearing during less than setting value, the speed lock can be free to slide, and allows to produce relative motion between end basin 5 and the lower support plate 9, and whole bearing is the one-way type bearing under this state.
When the relative sliding velocity of bearing during greater than setting value, the speed lock is locked and can not be free to slide, and does not allow to produce between end basin 5 and the lower support plate 9 relative motion, and whole bearing is a fixed bearing under this state.
Structure and principle thus, bearing of the present invention can be a conversion value with a movement velocity of setting, and changes between one-way support and fixed bearing, has had both advantages concurrently, thereby has compared with the bearing of prior art, has the anti-fall beam technique effect of better antidetonation.
In sum, described in this manual is several preferred embodiment of the present invention, and above embodiment is only unrestricted in order to technical scheme of the present invention to be described.All technician in the art all should be within claim protection domain of the present invention under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
