Detailed Description
The structure and the working principle of the damping type anti-falling beam anti-seismic support provided by the invention are further described in detail with reference to the accompanying drawings.
As shown in fig. 1, 2 and 3, the damping type anti-falling beam anti-seismic support provided by the present invention has a schematic structural diagram. The structure of the support comprises an upper support plate 1, a lower support plate 2, a support body 3 which is arranged between the upper support plate and the lower support plate and is composed of a stiffening steel plate 31 and a laminated rubber layer 32, and a guy cable mechanism 4 connected between the upper support plate and the lower support plate; seven (the number of holes can be set according to requirements) through holes 11, 12, 13 … 1n and 21, 22, 23 … 2n are respectively arranged in the upper support plate 1 and the lower support plate 2, and seven pull ropes 41, 42, 43 … 4n forming the pull rope mechanisms are respectively inserted into the through holes in the upper support plate and the lower support plate to form seven closed pull rope mechanisms 4. In above-mentioned support structure, because the stay cord that constitutes above-mentioned cable mechanism penetrates and forms the closed structure in the perforation in upper bracket board and the bottom suspension bedplate, the earthquake in-process, the closed stay cord that is formed at the support both sides and as an organic whole structure can automatic flexible adjustment, consequently effectively avoids the fixed support part that the stay cord caused stress concentration to appear, and leads to appearing the emergence that the atress inequality caused the whole damage phenomenon of support between each adapting unit that constitutes the support.
In the structure constituting the damping type anti-falling beam earthquake-proof support,
as shown in fig. 3, the stay cord 40 constituting the stay cord mechanism 4 is arranged as one, and sequentially penetrates through the through hole from the upper support plate to the lower support plate, and the head and the tail (two end parts of the stay cord) 44 and 45 are fixedly connected or respectively fixed on the upper support plate to the lower support plate, and the cable rope also penetrates through the through hole of the upper support plate and the through hole of the lower support plate, so that the stay cord mechanisms formed at two sides of the support plate can be relatively adjusted in a telescopic manner, and the purpose of the utility model can also be realized;
