Abstract
The utility model discloses an anti - stretch -draw pre -compaction instrument of jack, including cushion cap and support to and balance beam, finish rolling screw -thread steel, jack and steel shotcrete, balance beam sets up on the support, it is one pre -buried in the cushion cap that gasket no. 1, nut are passed through to the lower part of finish rolling screw -thread steel, and balance beam is passed on upper portion, and the steel shotcrete penetrates the finish rolling screw -thread steel through gasket no. 2 and puts on balance beam, and the jack is arranged in through gasket no. 3 and three anchors on the nut on the steel shotcrete. The utility model discloses lay balance beam on the support of setting up, finish rolling screw -thread steel pre -buried on the cushion cap passes balance beam, utilizes the anti - stretch -draw finish rolling screw -thread steel of jack to realize the pre -compaction effect. The utility model discloses utilizing the anti - stretch -draw pre -compaction of jack, controlling stretch -draw stress with the reading of oil meter, the pre -compaction precision is high, has convenience, swift characteristics, can improve work efficiency, shortens construction period, practices thrift the cost.
Description
Technical field
The utility model relates to a kind of jack anti-sheet and draws prepressing means, belongs to technical field of building construction.
Background technology
Pre-pressing bracket is one important procedure of Construction of continuous beam.Current, pre-pressing bracket majority uses sand pocket prepressing means, expends more manpower and materials and adds construction cost, also having a certain impact to construction period.
Summary of the invention
Technical problem to be solved in the utility model is the defect existed for prior art, provides a kind of jack anti-sheet reducing construction cost to draw prepressing means.
For solving this technical problem, the utility model provides a kind of jack anti-sheet and draws prepressing means, comprise cushion cap and support, and shoulder pole girder, fining twisted steel, jack and bracing members, described shoulder pole girder is set up on support, and the bottom of described fining twisted steel is pre-buried in cushion cap by pad one, nut one, and top is through shoulder pole girder, bracing members penetrates fining twisted steel by pad two and is placed on shoulder pole girder, and jack is placed on bracing members by pad three and nut three anchoring.
Described jack is hydraulic jack.
Beneficial effect: the utility model lays shoulder pole girder on the support set up, fining twisted steel pre-buried on cushion cap, through shoulder pole girder, utilizes jack anti-sheet to draw fining twisted steel to realize pre-compressed effect.The utility model utilizes jack anti-sheet to draw precompressed, controls tension stress with the reading of oil meter, and precompressed precision is high, has feature easily and efficiently, can increase work efficiency, and shortens the construction period, cost-saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 cushion cap, 2 supports, 3 shoulder pole girders, 4 fining twisted steels, 5 pad one, 6 nut one, 7 jack, 8 bracing members, 9 pad two, 10 nut two, 11 pad three, 12 nuts three.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is specifically described.
Figure 1 shows that structural representation of the present utility model.
The utility model comprises cushion cap 1 and support 2, and shoulder pole girder 3, fining twisted steel 4, jack 7 and bracing members 8.
Described shoulder pole girder 3 is set up on support 2.
The bottom of described fining twisted steel 4 is pre-buried in cushion cap 1 by pad 1, nut 1, and top is through shoulder pole girder 3.
Described bracing members 8 penetrates fining twisted steel 4 by pad 29 and is placed on shoulder pole girder 3.
Described jack 7 is placed on bracing members 8 by pad 3 11 and nut 3 12 anchoring.
Described jack 7 is hydraulic jack.
Utility model works principle and pressing step:
Described jack 7 utilizes oil meter reading to control tension stress: tighten the nut 3 12 above jack 7 before every grade of precompressed, stretch-draw is embedded in cushion cap 1 li of fining twisted steel 4; Bracing members 8 inner nut 2 10 is tightened after fining twisted steel 4 stretch-draw; Continue all the other fining twisted steels 4 of precompressed; After the equal precompressed of all fining twisted steels 4, proceed all the other rank precompressed according to same steps.
The utility model lays shoulder pole girder on the support set up, and fining twisted steel pre-buried on cushion cap, through shoulder pole girder, utilizes jack anti-sheet to draw fining twisted steel to realize pre-compressed effect.The utility model utilizes jack anti-sheet to draw precompressed, controls tension stress with the reading of oil meter, and precompressed precision is high, has feature easily and efficiently, can increase work efficiency, and shortens the construction period, cost-saving.
The above-mentioned embodiment of the utility model, just illustrates, is not only, and all changes within the scope of the utility model or in equivalent scope of the present utility model are all surrounded by the utility model.
