The light-weight jack hanger consists of a main load-carrying framework, an anchoring device and a hoisting and sliding device; wherein the main load-carrying framework comprises first steel channels, second steel channels and a screw rod. A rectangle framework is formed between the two second steel channels arranged horizontally and the screw rod arranged between the two second steel channels; the two first steel channels are vertically arranged at the lower part of the rectangle framework; the anchoring device consists of a cable fastener and a reverse bolt, and the two ends of the reverse bolt are respectively connected with the cable fastener and the main load-carrying framework; the hoisting and sliding device consists of a sliding trolley and a chain block, wherein the sliding trolley rotates on the second steel channels; and the chain block is arranged at the lower part of the sliding trolley. By utilizing the light-weight jack hanger, the construction efficiency is high, the labor intensity is low, and the construction plant can be saved.
Description
Technical field
The member of using when the utility model relates to a kind of precast beam stretch-draw, especially a kind of light-duty jack suspension bracket.
Background technology
The post stressed concrete precast beam is widely used in the bridge construction, and steel strand tension is a most key procedure in the precast beam construction.The jack weight of using during stretch-draw is big, and it moves horizontally all very difficult with vertical top.Fixing and the mobile dependence of jack heavy in the present construction manually cooperates jack to finish with easy tripod, and the tripod heaviness of field machining wastes time and energy when mobile, and the stretch-draw of a slice precast beam needs 6 people to cooperate just at least can finish inefficiency.Present engineering construction duration majority is all very nervous, uses heavy tripod its drawback of constructing more and more outstanding.Press for a kind of easy instrument successively and assist the stretch-draw of finishing steel strand.
The utility model content
The technical problems to be solved in the utility model provides a kind of efficiency of construction height, in light weight and can save the light-duty jack suspension bracket of construction plant.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of light-duty jack suspension bracket, and its key technology is: it is made up of primary load bearing framework, anchor device and lifting slide device;
Described primary load bearing framework comprises first channel-section steel, second channel-section steel and screw rod, and two horizontally disposed second channel-section steels and the screw rod of being located between two second channel-section steels constitute rectangular frame, vertically are provided with two first channel-section steels in described rectangular frame bottom;
Described anchor device is made up of sling and reverse bolt, and oppositely the bolt two ends connect sling and described primary load bearing framework respectively;
Described lifting slide device is made up of sliding machine and jack, and sliding machine rolls on described second channel-section steel, is provided with jack in described sliding machine bottom.
Further improve, above-mentioned primary load bearing framework also comprises is located at the 3rd channel-section steel that is used to play fixed supporting role between first channel-section steel and second channel-section steel.
Further improve, above-mentioned primary load bearing framework also comprises the crotch of being located at the first channel-section steel bottom.
Above-mentioned reverse bolt is reverse turnbuckle.
Preferably, above-mentioned sliding machine comprises that two two ends are provided with the roller bearing of rolling bearing, is provided with connecting rod between two roller bearings, is provided with the suspension reinforcing bar that is used to hang jack between two connecting rods, and described rolling bearing rolls in the groove of second channel-section steel.
Adopt the beneficial effect that technique scheme produced to be: 1, the utility model is in light weight, and conveniently moving can reduce labour intensity significantly, and the stretch-draw of a slice precast beam only needs two people just can easily finish, and good stability when constructing, and is difficult for toppling.
2, do not take the place of Liang Chang because of the utility model, but directly with it on the beam face, can save the place greatly.
The installation accuracy rate height of jack when 3, adopting the utility model construction, it is vertical, move horizontally conveniently, and translational speed is fast, and the work efficiency height can be saved the duration.
