Abstract
A kind of bidirectionally limited mechanism of lamination U-shaped steel plate, belong to engineering structure antidetonation, damping and wind resistance technical field, including lamination U-shaped steel plate (1), U-shaped steel plate fixed plate (5), draw back plate (3), push/pull slot (6) etc..Push/pull slot (6) is fixed in Seismic Isolation of Isolation Layer superstructure, and lamination U-shaped steel plate (1) gos deep into inside push/pull slot, draw back plate (3) is in push/pull slot (6) center.Draw back plate (3) has certain distance away from push/pull slot (6) inner cavity left and right ends.When large deformation occurs for shock isolating pedestal, position restrainer purchase can limit the deformation of Seismic Isolation of Isolation Layer in push-and-pull both direction, play the role of protecting isolations.
Description
Technical field
The present invention relates to a kind of position-limit mechanism of isolation structure, belong to engineering structure damping and technical field of isolation, mainly
For reducing deformation of the Seismic Isolation of Isolation Layer under big shake.
Background technology
Earthquake isolating equipment has the natural vibration period for extending building structure, avoids the function of seismic predominant period, can be in very great Cheng
Reduce the seismic response of building structure on degree.But for near-fault ground motion and other seismic waves rich in long period pulse, hold
Seismic Isolation of Isolation Layer is produced larger deformation, the people of building interior is produced sense of discomfort, even result in structural instability or shock isolating pedestal
Destruction.
For problems, buffering stop block can be increased as second defence line.Limiting device is according to the mode of action
Difference, can be divided into displacement-limited with dissipation device and fixed limiting device, the former can deform with the deformation of Seismic Isolation of Isolation Layer, by deforming
To the effect of energy consumption, there is a certain distance between the latter and shock isolating pedestal, only deform more than the preset space in Seismic Isolation of Isolation Layer
When limiter just play a role.Traditional limiting device, either elastic limit device or rigid limit device, all only
Thrust can be provided, the tensile capacity of limiting device cannot play, and cause the wasting of resources.U-shaped steel plate can be used as limiter, but soft
Steel U-shaped steel plate is by easily surrender after collision, easy brittle failure after hard steel U-shaped steel plate is collided.To solve problem above, this hair
It is bright to propose a kind of bidirectionally limited mechanism of lamination U-shaped steel plate.
The content of the invention
Technical scheme is as follows：
A kind of bidirectionally limited mechanism of lamination U-shaped steel plate, including lamination U-shaped steel plate (1), U-shaped steel plate fixed plate (5), push-and-pull
Plate (3), push/pull slot (6) etc..
The lamination U-shaped steel plate (1), as shown in Figure 1 and Figure 2, is formed by stacking by the U-shaped steel plate of multilayer different radii, is folded
Each layer U-shaped steel plate contact is close after conjunction.Lamination U-shaped steel plate underarm right end flushes, prepared screw-bolt hole at proximal head, lamination U-shaped steel
Plate is fixed in U-shaped steel plate fixed plate (5) by fixing bolt (4) by the bolt hole.Lamination U-shaped steel plate upper arm right end is in gingival cyst of mucous gland in the newborn
Raft type, the brachium of upper and lower two panels U-shaped steel plate is longer, and internal U-shaped steel plate length is alternate, prepared screw-bolt hole on longer arm, for
Draw back plate (3) connects.U-shaped steel plate is made of manganese steel, is carried out temper after making, its elastic deformability is reached most
It is excellent.
The draw back plate (3), as shown in figure 3, be made by common iron, with connecting key, connecting key and lamination U
The horse tooth trough of shape steel plate upper arm is connected, and is anchored with connection bolt (2).
The push/pull slot (6), as shown in figure 4, being formed by steel plate welding or directly casting, its left end is gate-type opening,
Open height is less than the height of draw back plate (3), and more than the gross thickness of lamination U-shaped steel plate (1), lamination U-shaped steel plate (1) is from this mouthful of depth
Enter, push/pull slot (6) right end is steel sealing plate, and for being connected with structure, front and rear sides are open, do not set sealing plate.
During installation, push/pull slot (6) is fixed in Seismic Isolation of Isolation Layer superstructure by its right end sealing plate, draw back plate (3) is solid
It is scheduled on lamination U-shaped steel plate upper arm, is positioned over center position inside push/pull slot, lamination U-shaped steel plate is fixed on by its underarm
In fixed plate (5).Since draw back plate (3) away from push/pull slot (6) inner cavity left and right ends has certain distance, when Seismic Isolation of Isolation Layer deforms
When, which reduces, and when distance is reduced to 0, draw back plate is contacted with push/pull slot, and lamination U-shaped steel plate plays a role, and limits shock insulation
Layer deformation, playing prevents that Seismic Isolation of Isolation Layer deformation is excessive, protects isolations.
Beneficial effect：
(1) structure diverse location can be arranged in as limiter using manganese steel lamination U-shaped steel plate, it is convenient, flexible；Can be with
Realize larger deflection, compared to U-shaped steel plate position-limit mechanism made of individual layer steel plate, its elastic deformation segment length, is not easy to surrender,
It is used multiple times；Elastic stiffness is big, can provide enough restoring forces, to prevent superstructure deformation excessive；And pass through difference
U-shaped steel type, realize the needs of different building structure, the anti-seismic performance of building can be effectively improved.
(2) due to that there is provided draw back plate and push/pull slot, the pushing-pulling bi-directional performance of lamination U-shaped steel plate can be made to be played,
Compared to traditional individual event limiting device, the present invention can save the limiter of half.
