Abstract
The utility model relates to a split head bar special for prestress. The split head bar special for prestress comprises a pair of supporting frames, supporting rods horizontally arranged on the two supporting frames, and a pair of limit rods respectively arranged on the supporting rods. A limit placing groove is formed between the two limit rods and the supporting rods. The utility model aims at providing the split head bar special for prestress which is simple in structure and good in stability.
Description
Technical field
The utility model relates to the special-purpose supporting steel bar of a kind of prestressing force.
Background technology
Use U-shaped supporting steel bar to fix bellows in the tradition construction, bending machine is crooked to be made and " U " type split heads just utilizes in manufacturing process, poor to the structure presstressed reinforcing steel locating effect of having relatively high expectations, the split heads height is difficult to accurate control, cause embedding precision not accurate enough, and easily rollover in the work progress, stability is bad, need with the fixing rear secondary adjustment of iron wire, time-consuming.
Summary of the invention
The purpose of this utility model is to overcome the existing defects of prior art, provides a kind of prestressing force simple in structure and that have good stability special-purpose supporting steel bar.
The purpose of this utility model is achieved through the following technical solutions: the special-purpose supporting steel bar of a kind of prestressing force, and it is characterized in that: it comprises pair of supporting, crosses at the cradling piece on two bracing frames and is divided into a pair of gag lever post on the cradling piece; Form spacing mounting groove between described two gag lever posts and the cradling piece.
Compared to prior art, the utility model has the advantage of: the utlity model has good stability, and formed a groove that bellows can hold just because be provided with a pair of gag lever post in the position of setting up bellows, so that the presstressed reinforcing steel embedded process need not again colligation, firm simple, effectively guaranteed the parabolic type structure that prestressed reinforcement is embedding.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the use state diagram of Fig. 1 structure.
Label declaration: 1 bracing frame, 1-1 indented bars, 1-2 round steel, 2 cradling pieces, 3 gag lever posts, 4 bellowss.
The specific embodiment
Below in conjunction with Figure of description and embodiment the utility model content is elaborated:
The embodiment schematic diagram of the special-purpose supporting steel bar of a kind of prestressing force that provides for the utility model as depicted in figs. 1 and 2, it comprises pair of supporting 1, crosses at the cradling piece 2 on two bracing frames 1 and is divided into a pair of gag lever post 3 on the cradling piece 2; Form spacing mounting groove between described two gag lever posts 3 and the cradling piece 2.Described spacing mounting groove be used for to be placed bellows 4, between support frame as described above 1 and cradling piece 2 and the gag lever post 3 by being welded to connect.
Support frame as described above 1 is triangular in shape, it comprise the indented bars 1-1 that is located at the bottom and lower end respectively with indented bars 1-1 two ends are fixed and the upper end is connected with cradling piece 2 round steel 1-2.The large I of leg-of-mutton bracing frame 1 is not identical, is used for the embedding parabolic type structure of assurance prestressed reinforcement, and cradling piece 2 and gag lever post 3 are done corresponding adjustment according to the size of triangle support frame 1.
Described gag lever post 3 is vertical on the cradling piece 2, and gag lever post 3 is indented bars.
