Description
Technical Field
The utility model belongs to the technical field of bridge beam supports constructs, specific saying relates to a novel prevent roof beam support that falls.
Background
When the support is used in daily life, the damping rubber body of the support can effectively transmit the dynamic load and the static load of the upper bridge structure to the bridge pier, and the vibration brought to the upper bridge structure by the dynamic load can be absorbed through the characteristics of rubber; when geological disasters occur, forces in all directions of the upper structure of the bridge, which are brought by transverse waves and surface waves of an earthquake, are absorbed by large deformation of the damping support and are provided for restoring force, so that the relative position of the damping support is finally kept unchanged, and if the generated displacement is too large, the displacement exceeds the displacement limit of the damping rubber body immediately, so that the beam body is damaged.
The chinese patent literature discloses various structures of the girder falling prevention support, but the structures are complicated, and only damage to the components is easily caused in the using process, thereby causing failure of the girder falling prevention function.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure and can effectively prevent falling the novel roof beam support that prevents that the roof beam takes place.
In order to achieve the above object, the utility model adopts the following technical scheme:
a novel anti-beam-falling support structurally comprises an upper support steel plate, a lower support steel plate and a damping rubber support body clamped between the upper support steel plate and the lower support steel plate; corresponding upper and lower stay rope pressing strips are arranged on corresponding surfaces of two sides of the upper support steel plate and the lower support steel plate, a plurality of through holes are arranged on the stay rope pressing strips, and steel wire ropes are connected in the through holes of the corresponding upper and lower stay rope pressing strips in series; two ends of the steel wire rope are respectively fixed with the corresponding inhaul cable pressing strips.
The additional technical characteristics of the novel anti-falling beam support further comprise:
-said wire rope is a continuous structure;
the steel wire rope is in a spring-shaped serial connection structure, and the section of the spring is oval;
the steel wire rope is of a wave-shaped serial connection structure;
the bottom surface of the upper support steel plate forming the support is of an anti-slip structure formed by multiple layers of annular concave rings, and the lower support steel plate is provided with a groove structure capable of enabling the damping rubber support body to be recessed.
The utility model provides a novel prevent roof beam support that falls compares with prior art, has following advantage: firstly, in the structure of the anti-falling beam support, the mechanism for preventing the falling beam is inhaul cable pressing strips which are respectively arranged on the two corresponding sides of the upper steel support plate and the lower steel support plate which form the support and are used for fixing the steel wire rope, and the steel wire rope is fixed through the through holes arranged on the inhaul cable pressing strips, so the anti-falling beam support has the characteristic of simple structure; secondly, because the steel wire rope with the stretching function is of an oval spring type serial connection structure, the steel wire rope not only has better directionality and can effectively control the sliding direction between the upper support and the lower support, but also has the characteristics of high stretching length and strength.

Detailed Description
The structure and the working principle of the novel anti-falling beam support provided by the invention are further described in detail with reference to the accompanying drawings.
Refer to fig. 1 and 2, for the utility model provides a structural schematic diagram of a novel prevent roof beam support that falls. The structure forming the bridge expansion joint comprises an upper support steel plate 1, a lower support steel plate 2 and a damping rubber support body 3 clamped between the upper support steel plate and the lower support steel plate; corresponding upper inhaul cable pressing strips 11, 12 and lower inhaul cable pressing strips 21, 22 are arranged on corresponding surfaces of two sides of the upper support steel plate and the lower support steel plate, a plurality of through holes 4 are arranged on the inhaul cable pressing strips, and a steel wire rope 5 in a spring shape (the section of the steel wire rope is circular but is preferably oval) is connected in series in the through holes 4 of the corresponding upper inhaul cable pressing strips 11, 21, 12 and 22; both ends 51, 52 of the wire rope are respectively fixed with the corresponding stay rope pressing strips. The principle is that the damping rubber body can effectively transmit the dynamic load and the static load of the upper structure of the bridge to the bridge pier, and can absorb the vibration brought to the upper structure of the bridge by the dynamic load through the characteristics of the rubber; when a geological disaster occurs, the forces in all directions of the upper structure of the bridge, which are brought by the transverse waves and the surface waves of the earthquake, are absorbed by the large deformation of the damping support and are provided for restoring force, so that the relative position of the damping support is finally kept unchanged, and if the generated displacement is too large, the displacement of the damping rubber body is exceeded immediately, the steel wire rope pull cable can effectively prevent the dislocation between the upper support steel plate and the lower support steel plate which form the support, namely when the longitudinal waves of the geological disaster are biased to the displacement generated by the resistance of the pier, the steel wire rope pull cable can effectively play a guarantee role.
In the structure of the novel anti-falling beam support,
as shown in fig. 2, the connection shape of the steel wire rope is a wave-shaped series connection structure, which can also achieve the purpose of the utility model; certainly, when the shape of the steel plate is an ellipse, the steel plate has better directivity, can effectively control the sliding direction between the upper support steel plate and the lower support steel plate, and can realize the characteristic of controlling the stretching length of the steel plate in the horizontal wave direction of the earthquake and simultaneously has the characteristic of high stretching degree because the length of the minor axis of the ellipse (namely the distance between the upper support steel plate and the lower support steel plate) can be set according to the sliding distance between the upper support steel plate and the lower support steel plate when the major axis of the ellipse is fixed;
the bottom surface of the upper support steel plate forming the support is provided with a plurality of layers of annular concave rings 13 to form an anti-slip structure, and the lower support steel plate is provided with a groove structure 23 capable of recessing the damping rubber support body 3; the anti-slipping structure and the groove structure 23 effectively ensure that the damping rubber support body can be positioned at the center of the pier.
