In order to take out locating rack under the situation of not cutting the earth, described easy unloading type latch comprises plug housing and 2 bolt rods, and described 2 bolt rod rear ends are contained in plug housing below and rotation down vertically through turning cylinder respectively, and plug housing is provided with draw ring.
In order to prevent that the easy unloading type latch from skidding off from connection holes, can on 2 bolt rods, be respectively equipped with anti-play boss, rotate in connection holes in order to prevent the easy unloading type latch, bolt rod can be selected for use waist shape bar.
For the ease of adjusting the capital absolute altitude that supports steel post, described locating rack is provided with length mark.
In order to improve the coaxial performance of locating rack and support steel post, the locating rack bottom is nested into support steel post top should be not less than 500mm, and for the ease of the capital absolute altitude of measuring and calculating support steel post, the locating rack upper end can exceed an aperture 500 mm.
Underground overlength of the present utility model supports the steel post locating rack, because will be embedded in underground overlength support steel post with locating rack extends to more than the ground, can accurately calculate and control the capital absolute altitude of support steel post by the length mark on the locating rack, again since locating rack to be sleeved on the distance that supports steel post longer, ignored in the suit gap, locating rack cover axis and the coaxial performance that supports between the steel post axis have been improved, also because the connector between locating rack and the support steel post uses the easy unloading type connector, particularly use the easy unloading type latch, after the concrete pouring that can be in finishing foundation ditch, upwards draw plug housing latch can be taken out in locating rack with drag hook or stay cord.Overcome with bolt and connected and after need excavating very dark soil layer, after finding and unloading positioning bolt, the defective that could will guide locating rack to hang out with loop wheel machine.Have simple and reasonable, easy to loading and unloading, be convenient to advantages such as correction, can with the capital absolute altitude that supports steel post by allowable variation ± 100mm be reduced to ± 15mm in, the center line and the departure between the vertical line that support steel post and reinforcing cage are adjusted in the 20mm for being no more than 100mm by allowable variation, can also under the situation that does not need to cut the earth, take out locating rack and reuse, can obviously improve the construction quality of deep foundation ditch, reduce labour intensity and increase work efficiency.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 be among Fig. 1 A-A to structural representation;
Fig. 3 is a kind of structural representation of easy unloading type latch.
The specific embodiment
Referring to accompanying drawing, 1 among the figure is locating rack, and 1-1 is the angle steel of locating rack, 1-2 is the batten plate of locating rack, and 1-3 is the connection holes of locating rack bottom, the 2nd, and the easy unloading type latch, 2-1 is a bolt rod, and 2-2 is a plug housing, and 2-3 is a turning cylinder, 2-4 is a draw ring, and 2-5 is anti-play boss, the 3rd, support steel post, 3-1 is the angle steel that supports steel post, and 3-2 is the batten plate that supports steel post, and 3-3 is the connection holes that supports steel post top, the 4th, reinforcing cage, the 5th, a hole.
Underground overlength of the present utility model supports the steel post locating rack, its locating rack 1 is welded by 4 angle steel 1-1 and batten plate 1-2, the inner side edge of described locating rack 1 is than the big 2～10mm of outer side edges that supports steel post 3, locating rack 1 bottom is sleeved on to be supported steel post 3 outsides and uses easy unloading type latch 2 to connect, and locating rack 1 top exceeds an aperture and calibrated back fixedly is lifted on the mouth in a hole 5.Its structure as depicted in figs. 1 and 2.
In order under the situation of not cutting the earth, to take out locating rack 1, described easy unloading type latch 2 comprises plug housing 2-2 and 2 bolt rod 2-1, described 2 bolt rod 2-1 rear ends are contained in the plug housing below through turning cylinder 2-3 respectively and also can rotate along turning cylinder 2-3, and plug housing 2-2 is provided with draw ring 2-4.Its structure as shown in Figure 3.
In order to prevent that the easy unloading type latch from skidding off from connection holes, can on 2 bolt rod 2-1, be respectively equipped with anti-play boss 2-5, in order to prevent that the easy unloading type latch from rotating in connection holes, bolt rod 2-1 can be designed to the waist shape bar of anti-rotation or cross section and be square, strip etc., the shape of connection holes is corresponding with bolt rod to get final product.
For the ease of adjusting the capital absolute altitude that supports steel post, described locating rack is provided with length mark.
In order to improve the coaxial performance of locating rack 1 and support steel post 3, locating rack 1 bottom is nested into support steel post top should be not less than 500mm, and for the ease of the capital absolute altitude of measuring and calculating support steel post 3, locating rack 1 upper end can exceed about 500 mm in an aperture.
During operation, behind pouring pile hole and clear hole, carry out laying of reinforcing cage 4 earlier, should guarantee when transferring reinforcing cage that it is concentric with stake hole 5, vertically transfer.When treating that reinforcing cage 4 tops are transferred apart from ground 2m, be fixed on the board.To support steel post 3 integral lifting with the 50t crawler crane again, when supporting steel post 3 and hang in the reinforcing cage 4 3m, it is integrally welded to support steel post 3 and reinforcing cage 4, will support steel post then and reinforcing cage together descends.When are disembarked in 1 meter left and right sides of platform at support steel post top, steel post is fixed on the board, then locating rack 1 bottom is sleeved on and supports steel post 3 outsides and use easy unloading type latch 2 to connect, after should noting inserting 2 bolt rods in the connection holes respectively when easy unloading type latch 2 connects, plug housing 2-2 need be pressed into 2 bolt rod 2-1 and become in-line, as shown in Figure 3, and then with locating rack 1 with support steel post 3 and together continues decline with reinforcing cage 4, fixedly be lifted on the mouth in a hole 5, as shown in Figure 1 near stake aperture and calibrated back up to locating rack 1 top.At this moment, because of supporting the pulling force that downward gravity of steel post 3 and locating rack 1 make progress, make plug-in mounting support bolt rod among the connection holes 1-3 of the connection holes 3-3 on steel post top and locating rack bottom and bear a kind of front end power that the rear end rotates that makes progress, but the power that 2 bolt rod 2-1 rear ends rotate respectively can't be rotated because of the effect of plug housing 2-2, and locating rack 1 can firmly be sling supporting steel post 3 and following reinforcing cage 4 thereof etc.Because easy unloading type latch 2 is contained in the dual-side that supports in the steel post 3, do not influence again the concrete construction of carrying out in the foundation ditch.After the concrete pouring in finishing foundation ditch, support steel post etc. all is fixed motionless, locating rack is become flexible to end earlier, can upwards draw plug housing 2-2 with drag hook or stay cord through draw ring 2-4 from locating rack is suitable for reading, in locating rack 1, take out easily after 2 bolt rod 2-1 can being extracted out from connection holes 1-3 and 3-3.Can under the situation that does not need to cut the earth, take out locating rack at last and reuse.
