Abstract
The utility model relates to a post-tensioned tension constructing tool, in particular to a prestressed tension jack moving frame, comprising an independent movable framework, wherein the upper transversal beam of the movable framework is provided with a movable pulley which can move along the transversal beam; the lower part of the movable pulley is hung with a hand-pull hoist which can be connected with the jack. The utility model can utilize the independent movable framework, movable pulley and hand-pull hoist, the jack can be moved to the working site in the filed and positioned under the manual condition, the construction speed is ensured, and the construction cost is saved. Compared with the prior art, the utility model has the advantages of simple and reasonable structure, easy manufacture, easy popularization and the like.
Description
Technical field
The utility model relates to post-stressed stretching construction instrument, especially a kind of prestressed stretch-draw jack movable stand.
Background technology
At present, in the bridge engineering application of assembling post-tensioned method prestressed concrete box beam more and more universal, and the most important thing especially of prestress engineering wherein.The stretch-draw of prestress wire directly influences case beam quality, simultaneously, also is the key factor of restriction case beam production cycle.Because the jack quality is heavier, move and consumption worker consuming time in place, largely influenced tensioning construction efficient.
The utility model content
The utility model is intended to solve that jack moves and problem slowly in place in the stretching process, and provide a kind of is fast effective saving of labor's prestressed stretch-draw jack movable stand, so that under the situation of and large-scale production big in prefabricated place, can the box girder tensioning in the length of time will be reached fast, shorten the case beam and take the platform bit time, enter next construction period as early as possible.
The technical scheme that the utility model solves described problem sampling is: a kind of prestressed stretch-draw jack movable stand, comprise an independently removable framework, the movable pulley that can move along this crossbeam is housed on the upper beam of described removable framework, and this movable pulley bottom is hung with the Chain block that can be connected with jack.
The utility model utilizes an independently removable framework and movable pulley and Chain block, just jack can easily be moved to job site and in place in the place under the condition of manpower, when having guaranteed construction speed, has saved construction cost.Compared with prior art, the utlity model has simple and reasonable, make easily, be easy to advantage such as popularization.
Description of drawings
Fig. 1 is a facade structures schematic diagram of the present utility model.
Fig. 2 is a side view of the present utility model.
Fig. 3 is schematic diagram in place for the utility model moves.
Among the figure: vertical beam 1, upper beam 2, movable pulley 3, Chain block 4, jack 5, tool box 6, base 7, mobile support wheel 8, case beam 9.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to accompanying drawing, this prestressed stretch-draw jack movable stand mainly is made of removable framework, movable pulley 3, Chain block 4 three parts.
As preferred version, the described removable framework of present embodiment is character, its two vertical beams of being made by steel pipe 1 and the upper beam made by channel-section steel 2 are solidified as a whole by welding, described vertical beam 1 bottom is welded with the base of being made by steel plate 7, and some mobile support wheels 8 are equipped with in these base 7 bottoms.Described base 7 tops are equipped with tool box 6.
Described movable pulley 3 is provided with two, is assemblied on the upper beam 2 by described channel-section steel structure, and the bottom of each movable pulley 3 all is provided with a ∪ connector.When tensioning construction is carried out at the scene, only need Chain block 4 is hung on the described ∪ connector, after by Chain block 4 jack 5 being sling again, by once jack 5 can be moved to the case Liang9Chu that needs stretch-draw to two people's travelling frames, regulate the horizontal and vertical position of movable pulley 3 and Chain block 4 control jack 5 again, make it accurately in place, can carry out the stretch-draw of prestress wire after in place.
Claims (3)
