Description
Technical field
The utility model is related to the tooling device in bridge, roadbed, tunnel self-compaction work progress, particularly a kind of from close
Real locating rack.
Background technology
, often will be in concrete bottom seating face seating track plates, and by upper during bridge, roadbed, constructing tunnel
The grout hole of lower penetrating orbit plate is starched to casting concrete between concrete bed and track plates, realizes self-compaction operation.In order to
Prevent the concrete grout poured through being overflowed between concrete bed and track plates, existing anti-spilled mode is only in track plates four
The self-compaction backplate that makes a circle is wrapped in all bottoms, and the grout hole through penetrating orbit plate up and down is poured between concrete bed and track plates
After concrete grout, concrete grout is yielding because of unbalance stress, causes track plates to produce and breaks away and rising phenomenon, track plates installation position
Put deviation.
The content of the invention
The utility model is in order to solve the above-mentioned technical problem there is provided one kind in bridge, roadbed, tunnel self-compaction operation
Cheng Zhong, can avoid concrete grout yielding because of unbalance stress, prevent track plates are produced from breakking away and rising phenomenon, track plates installation position
Put accurately self-compaction locating rack.
Technical solution of the present utility model is：
A kind of self-compaction locating rack, including crossbeam, it is characterized in that：Support is vertically arranged respectively at crossbeam two ends
Frame, laterally sets push rod I, push rod I to point to crossbeam middle vertical plane in support frame bottom by screw thread；Erected respectively in the side bottom of crossbeam two
Straight to set locating rack, locating rack bottom surface is higher than support frame bottom surface, and push rod II, push rod are laterally set by screw thread in locating rack bottom
II points to crossbeam middle vertical plane, and the cunning for running through crossbeam above and below being set respectively between the support frame of homonymy and locating rack is located on crossbeam
Dynamic pull bar, and clamp nut is set by screw thread on the top of sliding tie rod.
Further preferably, locknut I is set respectively positioned at support frame both sides on push rod I.
Further preferably, locknut II is set respectively positioned at locating rack both sides on push rod II.
Further preferably, support frame as described above is mounted by means of bolts on crossbeam two ends, is easy to dismounting.
The beneficial effects of the utility model are：
1st, due to being vertically arranged support frame respectively at crossbeam two ends, push rod I is laterally set by screw thread in support frame bottom,
The locating rack that bottom surface is higher than support frame bottom surface is vertically arranged respectively in the side bottom of crossbeam two, it is horizontal by screw thread in locating rack bottom
Push rod II is set, and during self-compaction operation, the push rod I adjusted respectively on support frame is acted against concrete bed both sides, then is divided
Push rod II that Tiao Jie be on locating rack is acted against the self-compaction backplate both sides for being trapped among track plates bottom surrounding, and by track plates
Adjust in concrete bed upper surface center, so that track plates are stabilized in into base upper surface center, it is therefore prevented that track plates
Produce sideslip phenomenon to occur, track plates installation site is accurate.
2nd, due on crossbeam positioned at homonymy support frame and locating rack between respectively set above and below run through crossbeam slip
Pull bar, and clamp nut is set by screw thread on the top of sliding tie rod, during self-compaction operation, in concrete bed both sides difference
Laterally inserted tail end carry nut crooked chisel, by positioned at the sliding tie rod of crossbeam both sides by being threadably mounted at respective side crooked chisel tail
On the nut at end, crossbeam is pressed firmly against on track plates by the clamp nut on regulation sliding tie rod top, makes track plates and coagulation
Native base is close to, it is therefore prevented that track plates produce rising phenomenon, and track plates installation site is accurate.
