The light turnbuckle screw has the advantages that: the central part has a structure of combining a plurality of swirling rods, and materials can be saved.
Description
Technical field
The utility model relates to a kind of bridge construction and uses utensil, particularly relates to a kind of light bridge construction with spending blue screw rod.
Background technology
Mostly the sidewall of existing viaduct is crashproof wall, and crashproof wall has higher safety compared with common railing.In the viaduct work progress, after the intact deck paving of plate-girder frame is intact, promptly begin the construction of crashproof wall; In it sets up, need fix it, existing generally is fixing jointly through pole and pull bar; Pole provides the power to extrapolation; Pull bar provides a power of inwardly drawing, and when thrust and pulling force balance, crashproof wall is promptly firmly fixed.
Pull bar one end catches on crashproof wall; The other end catches on the screw that bridge floor is squeezed into; When pulling force is not enough or too high, all adopt following two kinds of settling modes now: the one, promptly change pull bar length through changing pull bar, reach the effect that needs; But change pull bar and need waste great amount of time, and the pull bar cost of subsequent use polytypic excessively is high too; The 2nd, at an end of pull bar a telescopic regulating part is set, but but the turn part of existing regulating part all is to adopt column type, extremely inconvenient when turn, and waste material relatively.
The utility model content
The purpose of the utility model promptly is to overcome the deficiency of present technology, provides a kind of light bridge construction with spending blue screw rod, and its central module adopts the structure of a plurality of turn bar combinations, can save material.
The utility model is realized through following technical scheme: a kind of light bridge construction comprises central module, link A and link B with spending blue screw rod, and described central module comprises at least two turn bars; The two ends of all turn bars all are separately fixed on two turn heads; Be provided with the gap between the turn bar, also be provided with through hole on the turn head, be provided with internal thread in the through hole; And the hand of spiral of internal thread is opposite in the through hole of two turn heads; Link A comprises hook-like part and screw rod A, and link B comprises loop-shaped element and screw rod B, and screw rod A and screw rod B are provided with the external screw thread with the screw-internal thread fit of the through hole of turn head; The end of screw rod A is connected with hook-like part; The other end passes the through hole of one of them turn head, and the end of screw rod B is connected with loop-shaped element, and the other end passes the through hole of another turn head.
A described turn bar and turn integrated syndeton.
Described screw rod A and the integrated syndeton of hook-like part.
Described screw rod B and the integrated syndeton of loop-shaped element.
The length of described turn bar is greater than the summation length of screw rod A and screw rod B.
The beneficial effect of the utility model is: central module adopts the structure of a plurality of turn bar combinations, has the advantage of saving material.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of link A;
Fig. 3 is the structural representation of link B;
Among the figure, 1-central module, 2-link A, 3-link B, 4-turn bar, 5-turn head, 6-hook-like part, 7-screw rod A, 8-loop-shaped element, 9-screw rod B.
The specific embodiment
Below in conjunction with embodiment the utility model is done further to specify, but the structure of the utility model is not limited only to following examples:
Shown in Fig. 1～4, a kind of light bridge construction comprises central module 1, link A2 and link B3 with spending blue screw rod; Described central module 1 comprises at least two turn bars 4, and the two ends of all turn bars 4 all are separately fixed in two turns 5, are provided with the gap between the turn bar 4; Also be provided with through hole in the turn 5; Be provided with internal thread in the through hole, the hand of spiral of internal thread is opposite in the through hole of two turns 5, and link A2 comprises hook-like part 6 and screw rod A7; Link B3 comprises loop-shaped element 8 and screw rod B9; Screw rod A7 and screw rod B9 are provided with the external screw thread with the screw-internal thread fit of turn 5 through hole, and the end of screw rod A7 is connected with hook-like part 6, and the other end passes the through hole of one of them turn 5; The end of screw rod B9 is connected with loop-shaped element 8, and the other end passes the through hole of another turn 5.
Described turn bar 4 and turn 5 an integrated syndeton; Screw rod A7 and hook-like part 6 integrated syndetons; Screw rod B9 and loop-shaped element 8 integrated syndetons.
The length of described turn bar 4 can reach maximum adjustable range greater than the summation length of screw rod A7 and screw rod B9.
Because the hand of spiral of the internal thread in the through hole of two turns 5 is opposite; When turn bar 4 during by turn; Drive the turn of turn 5; Turn 5 is promptly opposite along the screw rod A7 and the screw rod B9 direction of motion, but distance is fixed between two turns 5, thus between screw rod A7 and the screw rod B9 be each other near or each other away from.
The operating principle of the utility model: the hook-like part 6 of the link A2 of this device catches on bridge floor, an end of loop-shaped element 8 cylinder lever connecting rods of link B3, and the other end of pull bar then is connected on the crashproof wall; When the pulling force of crashproof wall is not enough; Turn turn bar 4, make between link A2 and the link B3 approaching each other, the pulling pull bar; Thereby increase the pulling force of crashproof wall, guaranteed the fixing of crashproof wall.
The turn bar 4 of the utility model can insert between two turn bars 4 with club can't be with the direct turn of hand the time, grasps the club other end then, and promptly very turn is realized in the labour-saving.
