Abstract
The utility model discloses a turnbuckle screw for fastening the side wall of a bridge during construction of a viaduct bridge. The turnbuckle screw comprises a central part (1), a connection part A (2) and a connection part B (3); the central part (1) is cylindrical; a through hole (4) is formed in the central part (4) along the height direction; inner threads which have the direction opposite to a spiral direction are formed on the through hole (4) from two ends to a center; the connection part A (2) comprises a hooked piece (6) and a screw rod A (7); and the connection part B (3) comprises a circular piece (8) and a screw rod B (9). The utility model has the advantages that: the turnbuckle screw is used between a pull bar and a bridge surface; the length of a body can be increased or reduced slowly by swirling a swirl rod, so the aims of pulling and loosening the pull bar and increasing or reducing tensile force of the pull bar are fulfilled; and the turnbuckle screw has the advantage of simple structure, convenience in use and the like.
Description
Technical field
The utility model relates to a kind of bridge construction and uses utensil, particularly relates in a kind of viaduct construction to be used for the blue screw rod of spending of fastening bridge sidewall.
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, and pole provides the power to extrapolation, and pull bar provides a power of inwardly drawing; When thrust and pulling force balance, crashproof wall is promptly firmly fixed, and existing 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, and can be through changing pull bar; Reach the effect of needs, but changing pull bar need waste great amount of time, and the pull bar cost of subsequent use polytypic excessively is high too.
The utility model content
The purpose of the utility model promptly is to overcome the deficiency of present technology; Provide in a kind of viaduct construction and be used for the blue screw rod of spending of fastening bridge sidewall; Be used between pull bar and the bridge floor, the length of himself can realize fine setting, thereby reaches the effect that increases or reduce draw-bar pull.
The utility model is realized through following technical scheme: be used for the blue screw rod of spending of fastening bridge sidewall in the viaduct construction; Comprise central module, link A and link B, described central module is a cylinder, and central module is provided with through hole along short transverse; The two ends of through hole are respectively arranged with the opposite internal thread of the hand of spiral to the center; 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 through hole; The end of screw rod A is connected with hook-like part; One end of other end connecting through hole, the end of screw rod B is connected with loop-shaped element, the other end of other end connecting through hole.
Described central module center is provided with at least one handle.
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 central module is greater than the summation length of screw rod A and screw rod B.
The beneficial effect of the utility model is: be used between pull bar and the bridge floor; Through the turn central module; Can slowly increase or reduce the length of body; Thereby realize the pulling pull bar and loosen pull bar that to the purpose of pull bar increase or minimizing pulling force, the utility model also has advantages such as simple in structure and easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of central module;
Fig. 3 is the structural representation of link A;
Fig. 4 is the structural representation of link B;
Among the figure, 1-central module, 2-link A, 3-link B, 4-through hole, 5-handle, 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, be used for the blue screw rod of spending of fastening bridge sidewall in the viaduct construction, comprise central module 1, link A2 and link B3; Described central module 1 is a cylinder; Central module 1 is provided with through hole 4 along short transverse, and the two ends of through hole 4 are respectively arranged with the opposite internal thread of the hand of spiral to the center, 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 through hole 4, and the end of screw rod A7 is connected with hook-like part 6, an end of other end connecting through hole 4; The end of screw rod B9 is connected with loop-shaped element 8, the other end of other end connecting through hole 4.
Described central module 1 center is provided with at least one handle 5, holds handle 5 turn central module 1 very effortlessly, and handle 5 can be to be fixed on the central module 1 through screw thread, also can with 1 integrated connection of central module.
Screw rod A7 and hook-like part 6 integrated syndetons; Screw rod B9 and loop-shaped element 8 integrated syndetons have guaranteed good connection.
The length of central module 1 can reach maximum adjustable range greater than the summation length of screw rod A7 and screw rod B9.
The internal thread that through hole 4 two ends of the utility model central module 1 all are provided with to the center; And it is in the opposite direction; When center parts 1 during by turn; Screw rod A7 and screw rod B9 in the through hole 4 promptly can move along hand of spiral, thus promptly can be each other between screw rod A7 and the screw rod B9 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, hold handle 5 turn central modules 1, make between link A2 and the link B3 approaching each other; The pulling pull bar; Thereby increase the pulling force of crashproof wall, make the pulling force and the thrust-balancing of crashproof wall, realized the fixing of crashproof wall very simply.
