Description

Pile positioning rechecker

Technical Field

The utility model relates to a location rechecker, concretely relates to stake location rechecker.

Background

In the traditional mechanical pore-forming cast-in-place pile construction of the building engineering, four direction control points are led out outwards through a pile center point, and the four control points are respectively inserted into the ground by using short steel bars and serve as external leading control points. When the pile position is rechecked, the four control points are connected in a cross way by adopting two thin lines, and the cross point is the central point of the pile. The survey crew need handheld instrument alignment intersect to measure and recheck, the instrument bottom is in unsettled state this moment, for guaranteeing measuring accuracy, survey crew is at the recheck in-process, the measuring instrument must guarantee the position accuracy, can not rock at will, so as to avoid leading to instrument and intersect to be misaligned because of rocking, influence the accuracy of rechecking, and the stake construction is all that manual fit machinery goes on, the destruction of control point can both be caused in every operation, the construction operation of whole process is not only complicated but also loaded down with trivial details, and the operation requirement to survey crew is higher.

Chinese patent with application number 201110377438.8, application date 2011-11-24 discloses "a stake position locator", including a stereoplasm plank, the stereoplasm plank is circular, and its centre of a circle sets up a location centre bore, and uses the centre of a circle to set up two mutually perpendicular's cross fretwork frame for the nodical in longitudinal axis and horizontal axis direction, and its circumference is the peripheral location circle of stake external diameter. The locator is complex to manufacture, and all the axes of a single project need to be lofted in a construction site, and then the locator is used for determining the pile position; in addition, the position of the pile can be determined by the positioner only through the existing axis, and whether the pile position after hole forming meets the design requirement or not can not be rechecked.

Disclosure of Invention

An object of the utility model is to overcome the not enough of prior art, provide a stake location rechecking ware that has improved stake position rechecking accuracy and efficiency of construction.

In order to achieve the above purpose, the utility model discloses a technical scheme is:

the utility model discloses a stake location rechecking ware, include the bolt that sets up along vertical direction, the nut of bolt has the centre bore be connected with the nut on the lower part threaded rod of bolt, superpose rotation cover about three steel bar support's one end is respectively through the ring cover between the nut of bolt and the nut, be provided with 90 crotch respectively at three steel bar support's the other end, the crotch is used for hooking establish on being located subaerial protective barrel top circumferencial direction outer wall perhaps the ground setting at stake hole edge is inserted to the crotch establish on being located subaerial protective barrel top circumferencial direction outer wall perhaps during the ground setting at stake hole edge is inserted to the crotch, the bolt be located protective barrel central point and put or stake hole central point puts, the nut centre bore of bolt is used for inserting the landing leg of measuring instrument in order to support the measuring instrument.

Compared with the prior art, the utility model discloses following beneficial effect has:

the complexity and the complexity of pile position rechecking are effectively simplified, the accuracy of the pile position rechecking is ensured, and the construction efficiency of pile construction is improved.

Drawings

Fig. 1 is a schematic structural view of a pile positioning rechecker of the present invention;

FIG. 2 is a schematic view of the pile position rechecker of FIG. 1 in use for rechecking a pile position;

figure 3 is a top view of the pile position rechecker of figure 2.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-3, the utility model discloses a stake location rechecker 5, include along the bolt 1 of vertical direction setting, the nut of bolt 1 has the centre bore be connected with nut 2 on the lower part threaded rod of bolt 1, superpose respectively from top to bottom through the ring cover and rotate the cover and overlap between the nut of bolt and the nut, be provided with 90 crotch respectively at the other end of three steel bar support 3, according to the operation requirement, the crotch is used for hooking establish on the 6 top circumference of a protecting cylinder outside wall that lie in above-ground or the ground setting at hook insertion stake hole circumferencial direction edge. When the hook is hooked on the outer wall of the top of the pile casing above the ground or inserted into the ground at the edge of the pile hole, the bolt is positioned at the center of the pile casing or the center of the pile hole, and the nut center hole of the bolt 1 is used for inserting the supporting leg of the measuring instrument 4 to support the measuring instrument 4.

The use method of the device is as follows:

and (4) determining the center point of the pile by using the measuring instrument 4, and trying to form a hole when the pile driver is in place to prepare for embedding the pile casing.

1. Pile machine examination pore-forming is accomplished the back, buries underground before protecting a section of thick bamboo, will the utility model discloses a 3 crotch of 5 three steel bar support of stake location rechecking ware insert the ground setting at stake hole circumferencial direction edge, carry out the rechecking of first time stake position.

2. And supporting the bottom of the measuring instrument 4 on a nut of the bolt 1, and measuring the deviation between the center point of the pile hole and the center point of the designed pile position.

3. And the position deviation meets the design specification requirement, and the pile casing is embedded. If the pile hole position is not in accordance with the requirement, the pile hole position needs to be corrected again, and then the pile casing is buried.

4. And after the pile casing 6 is buried, the pile positioning rechecker is used again to recheck the pile position for the second time. And (4) placing the pile positioning rechecker at the top of the pile casing, wherein the center of the pile casing is consistent with the center of the rechecker.

5. Placing the measuring instrument at the center of the rechecker, measuring the deviation between the center point of the pile casing and the center point of the designed pile position, wherein the deviation meets the design standard requirement, and performing the next construction; if not, the pile casing is embedded again until the deviation meets the standard requirement.
