Abstract
The utility model relates to a device that carries out stretch -draw and locking to prestressed anchorage pole of muscle of giving first place to with reinforcing bar, reinforcing bar front end carry out mantle fiber processing, adopt nut, backing plate fixed in advance, and the mantle fiber front end adopts connector and steel strand wires zonulae occludens, and steel strand wires pass the limiting plate through the hole site, are connected with stressing jack, and stressing jack passes through high pressure fuel pipe and links to each other with hydraulic pump, air -vent valve and digital display manometer. The utility model discloses the device will convert the stretch -draw to steel strand wires to the stretch -draw of reinforcing bar into, and the stretching force is accurate, simple structure. Simultaneously, adopt the nut that excels in to lock the reinforcing bar, greatly made things convenient for with reinforcing bar the give first place to stretch -draw and the locking of the prestressed anchorage pole of muscle, convenient operation, safe and reliable.
Description
Technical field
The utility model relates in geotechnical engineering the stretch-draw and the locking that take reinforcing bar as main rib prestressed anchor pole.
Background technology
With reinforcing bar be main rib prestressed anchor pole can convenient stretch-draw and the accurate locking key that is its application and promotes, press nut to reinforcing bar for the stretch-draw of the prestressed anchor of main muscle and locking mainly adopt artificial spanner to turn round or adopt anchorage of reinforcement to carry out stretch-draw to realize at present, turn round pressure nut according to artificial spanner and be then limited to manpower, effective latching force does not reach designing requirement, extreme influence supporting effect; Carry out stretch-draw according to anchorage of reinforcement, then cost is high.
Utility model content
The purpose of this utility model be to improve with tensioning fixation method, improve anchor pole tensioning fixation construction quality, guarantee Foundation Pit Support Design object and construction effect.
A kind of prestressed anchor to being main muscle with reinforcing bar carries out the device of stretch-draw and locking, comprise indented bars, it is characterized in that: indented bars 7 one end is anchored in Rock And Soil 6 by stretching into grouting soil 8, the other end is outside Rock And Soil, and Rock And Soil interface adopts nut and anchor plate 14 to be fixed;
The indented bars other end outside Rock And Soil carries out mantle fiber, connects steel strand by connector; Steel strand are by preformed hole position through limiting plate, and be connected with stretch-draw jack, stretch-draw jack is connected with hydraulic pump by high-pressure oil pipe, and hydraulic pump arranges pressure regulator valve and digital display manometer.
Connector is utilized indented bars mantle fiber section to be connected with steel strand.
The utility model adopts hydraulic pump, stretch-draw jack carries out stretch-draw by steel strand power transmission to the prestressed anchor being main muscle with reinforcing bar.The utility model will be converted to steel strand tension to reinforced bar stretching by connector, and tension operation is convenient, and stretching force is accurate.
When the utility model stretching force meets design requirement, adopt high-strength nut, lock.Fix high-strength nut by spanner, lock reinforcing bar, locking means is easy, cheap.
Accompanying drawing explanation
Fig. 1 is generalized section of the present utility model.
In figure:
1, stretch-draw jack 2, steel strand
3, limiting plate 4, connector
5, indented bars mantle fiber section 6, Rock And Soil
7, indented bars 8, grouting soil
9, high-pressure oil pipe 10, pressure regulator valve
11, digital display manometer 12, hydraulic pump
13, high-strength nut 14, anchor plate
Detailed description of the invention
1 implementation process of the present utility model is described by reference to the accompanying drawings.
A kind of easy and accurately the prestressed anchor being main muscle with indented bars is carried out to the device of stretch-draw, comprise indented bars, indented bars 7 one end is anchored in Rock And Soil by stretching into grouting soil, the other end 5 is outside Rock And Soil, outside reinforcing bar carries out mantle fiber processing, employing high-strength nut 13, anchor plate 14 pre-fix, reinforcing bar mantle fiber end 5 is by connector 4 and steel strand 2 compact siro spinning technology, steel strand 2 passing hole position is through limiting plate 3, connect stretch-draw jack 1, stretch-draw jack 1 is connected with hydraulic pump 12 by high-pressure oil pipe 9.
Described hydraulic pump 11 is provided with pressure regulator valve 10 and digital display manometer 11.
Described high-strength nut 13 adopts spanner to fix.
The course of work is: first pre-fix with high-strength nut, anchor plate, connector is adopted to be connected with reinforcing bar mantle fiber section by steel strand, steel strand are connected with stretch-draw jack through limiting plate by preformed hole position, and stretch-draw jack is connected with hydraulic pump, pressure regulator valve, digital display manometer by high-pressure oil pipe.Carry out Manual pressurizing after assembling, to predetermined stretching force, adopt spanner to fix high-strength nut.After fixing, shed prexxure of the hydraulic pump, according to contrary orderly release stretch-draw jack, limiting plate, connector are installed, so far one is main muscle with indented bars prestressed anchor stretch-draw is complete.
The device of this prestressed anchor stretch-draw to being main muscle with reinforcing bar and locking, structure is simple, cheap, installs and convenient disassembly.By the stretch-draw that connector will transform the stretch-draw of reinforcing bar steel strand, reduce the labour intensity of workman, improve operating efficiency.
