Description
Technical field
The utility model relates to the anti-fall of a kind of bridge, architectural engineering component more particularly to a kind of adjustable drag-line stroke
Beam support.
Technical background
Bridge pad is beam body and pier links tie, meets the demand of the functions such as the carrying, displacement, corner of beam body,
After the displacement that beam body occurs under extreme conditions exceeds expected displacement, support can be destroyed, and bridge superstructure is detached from branch
Seat, beam body can fall the serious consequence of beam, the existing anti-fall beam support with anti-fall girder apparatus, and anti-fall girder apparatus is generally adopted
The mode for connecting drag-line component between the upper lower steel plate (upper and lower support plate) of support is taken, prevents beam body from falling beam to reach
Purpose.
Have with anti-fall girder apparatus anti-fall beam support the problem is that:
1. the drag-line of anti-fall girder apparatus is directly anchored between the upper lower steel plate of support, the stroke of drag-line component is non-adjustable
Section, causes the effective travel of drag-line on support inconsistent, cannot cooperate with and play a role, after super expected displacement occurs for beam body,
Part drag-line elder generation stress causes it to destroy first, prevents entire drag-line component from playing anti-fall beam action；
2. some is with the anti-fall beam support for adjusting drag-line component stroke, as CN201420075951 drag-line subtracts shock insulation branch
Seat needs to process screw thread in stay cable end, then being threaded into stay cable end in adjusting nut, by the depth that is screwed into come
Adjust the effective travel of drag-line, drag-line be finally pressed in by upper and lower support plate using upper and lower briquetting, and using anchor bolt into
Row fastening, this structure not only construct complicated, complicated for operation, but also cost is high.
Utility model content
Girder falling branch simple, that drag-line stroke is adjusted that the technical problem to be solved by the present invention is to provide a kind of structures
Seat, to overcome prior art above shortcomings.
The technical scheme adopted by the utility model is that:
A kind of anti-fall beam support of adjustable drag-line stroke, including support body, the upper bracket plate of the support body with
M anti-fall girder apparatus is connected between lower support plate, the M anti-fall girder apparatus structure is identical, including drag-line and anchor,
The drag-line is connect with upper bracket plate and lower support plate respectively by being connected to the anchor at its both ends；
The anchor includes anchor-hold head and anchor bolt, and the both ends of the drag-line are tight by anchor-hold head hoop
It is respectively arranged among the blind hole of upper bracket plate and lower support plate, blind hole outer end passes through the anchor bolt anchor of central through hole form
Gu being equipped between the anchor-hold head and anchor bolt N number of for adjusting the adjusting gasket of drag-line effective travel；
Arbitrary integer of the numerical value of above-mentioned M and N between 1-999.
Its further technical solution is: the adjusting gasket is the annulus steel with a thickness of 0.5mm, 1mm, 1.5mm or 2mm
Piece.
Its further technical solution is: the support body subtracts shock insulation for friction pendulum support or hyperboloid ball-type
Support or pot bearing or spherical bearing or shock absorption and insulation rubber support.
Due to taking above scheme, a kind of anti-fall beam support of adjustable drag-line stroke of the utility model has and has as follows
Beneficial effect:
1. a kind of anti-fall beam support of adjustable drag-line stroke of the utility model, the upper and lower support plate of support body
Between connect M anti-fall girder apparatus, anti-fall girder apparatus includes drag-line and anchor, and the both ends of drag-line pass through anchor-hold head hoop
It is tightly respectively arranged among the blind hole of upper bracket plate and lower support plate, blind hole outer end passes through the anchor bolt anchor of central through hole form
Gu being not only simple in structure compared with the anti-fall beam support of traditional drag-line, operating convenient, safe and reliable, and low cost, favorably
In reduction engineering cost；
2. being equipped between the anchor-hold head and anchor bolt of the utility model anchor N number of has for adjusting drag-line
The adjusting gasket of stroke is imitated, adjusting gasket is the annulus steel disc with a thickness of 0.5mm, 1mm, 1.5mm or 2mm, and when installation can pass through
The gasket of different-thickness scale is combined, and the effective travel for adjusting drag-line in advance is consistent it, fills multiple girder fallings
The Cable forces set are uniform, coordinate stress, to improve the service life of anti-fall girder apparatus, it is ensured that the safety of bridge or building.
With reference to the accompanying drawings and examples to a kind of skill of the anti-fall beam support of adjustable drag-line stroke of the utility model
Art feature is further described.
