As shown in Figures 1, 2, 3, and 4, the utility model provides a corridor shock-isolation support, including: five layers of flat plates stacked sequentially from top to bottom: upper top plate 1, upper sliding plate 2, middle plate 3 , the lower plate 4, the lower base plate 5 and the limit baffle plate that limits the displacement between the five layers of plates. Wherein, the upper top plate 1, the middle plate 3 and the lower bottom plate 5 are square, and the upper slide plate 2 and the lower slide plate 4 are rectangles whose sides are long sides, but not limited thereto. A set of planar sliding friction pairs are respectively set between the upper top plate 1 and the upper slide plate 2, between the upper slide plate 2 and the middle plate 3, between the middle plate 3 and the lower plate 4, and between the lower plate 4 and the lower bottom plate 5. Four groups of plane sliding friction pairs are arranged between the five-layer flat plates of the utility model, and the layers can respectively translate in translation. Moreover, the length directions of the upper slide plate 2 and the lower slide plate 4 are perpendicular to each other, so that the corridor shock-isolation bearing can independently move in two directions in a plane, and can move in any direction in the plane. The utility model releases the displacement in any direction of the corridor during the earthquake through the horizontal movement between the above-mentioned five-layer slabs.

In this embodiment, the limiting baffles include a pair of upper side baffles 81 and a pair of upper limit baffles 91 arranged on the upper side baffles 81 , and a pair of lower side baffles arranged on the lower side baffles 82 . Baffle plate 82 and a pair of lower limiting plates 92 . The lower ends of the upper lateral baffles 81 are respectively connected to the first outer surfaces of the middle plate 3 , and the upper ends are respectively connected to the outer surfaces of the upper top plate 1 . The upper side baffle plate 81 blocks the two ends of the upper slide plate 2 in the length direction, and the upper slide plate 2 is guided by the upper side baffle plate 81 to slide along the width direction of the upper slide plate 2 . Upper ends of the lower side baffles 82 are respectively connected to the second outer surface of the middle plate 3 , and lower ends are respectively connected to the outer surfaces of the lower bottom plate 5 . The lower side baffle plate 82 blocks the two ends of the lengthwise direction of the slide plate 4 , and the slide plate 4 is guided by the lower side plate 82 to slide along the width direction of the slide plate 4 . Moreover, the upper side baffle plate 81 extends downwards beyond the middle plate 3 to limit the sliding stroke in the width direction of the lower slide plate 4, and the lower side baffle plate 82 extends upwards beyond the middle plate 3 to limit the width direction of the upper slide plate 2.

Moreover, the difference between the width of the upper slider 2 and the side length of the square is the stroke of the upper slider 2 in the width direction (the upper slider 2 can translate along the Y-axis direction), and the difference between the width of the lower slider 4 and the side length of the square is the lower stroke. The stroke of the slide plate 4 in the width direction (the lower slide plate 4 can translate along the X-axis direction), if the width of the upper slide plate 2 or the lower slide plate 4 is too wide, the sliding stroke will be reduced and sufficient displacement cannot be released. Therefore, preferably, the width of the upper sliding plate 2 and/or the lower sliding plate 4 is greater than or equal to one fourth of the side length of the square, and less than or equal to one half of the side length of the square. More preferably, the width of the upper sliding plate 2 and/or the lower sliding plate 4 is one third of the side length of the square, but it is not limited thereto.

Moreover, since the upper sliding plate 2 can be displaced relative to the upper top plate 1 and the middle plate 3, and the lower plate 4 can be displaced respectively relative to the middle plate 3 and the lower bottom plate 5, the utility model can release the horizontal displacement in sections, making the corridor The shock-isolation bearing releases more displacement in a smaller plane size.

In a variation example, the upper top plate 1, the middle plate 3 and the lower bottom plate 5 can also be rectangles of the same size, and the upper slide plate 2 and the lower slide plate 4 are adjusted according to the length of the long side or short side of the rectangle. The structure in which the length and width of the top plate 1, the upper slide plate 2, the middle plate 3, the lower plate 4 and the lower base plate 5 are adjusted also falls within the protection scope of the present utility model.

Four groups of plane sliding friction pairs in the utility model are respectively as follows: the bottom surface of the upper top plate 1 is connected with a first stainless steel plate 61, and the upper top surface of the upper slide plate 2 is connected with a first plane slide plate 71, and the first stainless steel plate 61 is connected with the first stainless steel plate 61. A plane sliding plate 71 is in surface contact, and the plane slides. The lower bottom surface of the upper slide plate 2 is connected with a second plane slide plate 72, and the upper top surface of the middle plate 3 is connected with a second stainless steel plate 62. The second plane slide plate 72 is in surface contact with the second stainless steel plate 62, and plane slides. The lower bottom surface of the middle plate 3 is connected with a third stainless steel plate 63, and the upper top surface of the lower plate 4 is connected with a third plane slide plate 73, the third stainless steel plate 63 is in surface contact with the third plane slide plate 73, and plane slides. The bottom surface of the lower plate 4 is connected with a fourth plane slide 74, and the top surface of the bottom plate 5 is connected with a fourth stainless steel plate 64. The fourth plane slide 74 is in surface contact with the fourth stainless steel plate 64, and the plane slides. Wherein the first plane slide plate 71, the second plane slide plate 72, the third plane slide plate 73 and the fourth plane slide plate 74 are all polytetrafluoroethylene materials (Polytetrafluoroethylene, plastic king), and the friction coefficient of polytetrafluoroethylene is extremely low, has Excellent lubrication, corrosion resistance and long service life. The corridor shock-isolation support of the utility model adopts 4 layers of polytetrafluoroethylene material, so that the corridor shock-isolation support also has a good shock-isolation effect in the vertical direction. And, between the first stainless steel plate 61 and the first plane slide plate 71, the second plane slide plate 72 and the second stainless steel plate 62, the third stainless steel plate 63 and the third plane slide plate 73, the fourth plane slide plate 74 and the fourth stainless steel plate 64 Silicone grease is applied to the contact surfaces between them, which further reduces the friction coefficient and makes it easier to slide, thereby enhancing the vibration isolation ability in the horizontal direction.

The state of implementation of the present utility model is as follows:

As shown in Figures 5 and 6, the corridor isolation support of the present invention (with Figure 4 as the initial state) is affected by an earthquake and is displaced by a force in the X-axis direction. The upper top plate 1, the upper slide plate 2, and the middle plate 3 are blocked by the upper side baffle plate 81 (the upper top plate 1 and the middle plate 3 still overlap), and will not move, but the middle plate 3 and the lower plate 4, and the lower plate 4 and the lower bottom plate 5 through sliding friction to jointly release the displacement. (Of course, it is also possible that the displacement only occurs between the middle plate 3 and the lower plate 4 or only between the lower plate 4 and the lower bottom plate 5, it is not limited thereto)

As shown in Figures 7 and 8, when the corridor isolation bearing of the present invention encounters a strong earthquake, it is subjected to an extremely strong force in the X-axis direction and continues to undergo a large amount of displacement. The upper top plate 1, the upper slide plate 2, and the middle plate 3 are blocked by the upper side baffle plate 81, and they will not move anyway, but the middle plate 3 and the lower plate 4, the lower plate 4 and the lower bottom plate 5 are in contact with each other through sliding friction as much as possible. Release a large amount of displacement until one side of the lower plate 4 is blocked by the lower end of the upper side baffle plate 81 (the part beyond the middle plate 3), and the other side is blocked by the lower limit plate 92 on the lower bottom plate 5, and the middle plate 3. The displacement between the lower plate 4 and the lower plate 5 is maximized and released. The upper roof 1 and the middle plate 3 are translated along the X-axis direction, away from the reference position of the lower plate 5, which fully meets the requirements for high-magnitude earthquakes. Displacement release requirements.

Similarly, on the basis of the state shown in Figures 7 and 8, through the action of the upper slide plate 2, the upper top plate 1 can also be displaced along the Y-axis direction, passing between the upper top plate 1, the upper slide plate 2, and the middle plate 3. The maximum displacement of is released (as shown in FIG. 9 ), so that the upper top plate 1 is further away from the reference position of the lower bottom plate 5 through translation along the Y-axis direction. In addition, by adjusting the amount of displacement in the X-axis direction and the Y-axis direction, displacement in any direction can be formed. In case of an earthquake, the lower bottom plate 5 can be used as the reference, and the upper roof 1 can simultaneously displace the X-axis and the Y-axis, so as to decompose the force in any direction, and fully protect the corridor and the buildings connected with the corridor.

The utility model also provides a corridor structure, the corridor and the main body of the building are connected with the above-mentioned corridor shock-isolation support, the corridor is fixed on the upper top surface of the upper roof 1, and the lower bottom surface of the lower bottom plate 5 is fixed to the main body of the building. .

To sum up, it can be seen that the corridor isolation bearing and the corridor structure of the utility model have all the functions of ordinary sliding steel bearings, and can resist earthquake force and wind pressure in any horizontal direction, and realize protection without dead angle in all directions, and the protection effect is Good; the corridor shock-isolation bearing of the utility model has a compact structure in the height direction, and the overall height is smaller than that of a general sliding steel bearing; and the bearing capacity is extremely high, the maintenance is simple, and the installation is convenient; the product is small in size, saves space and increases the appearance .
