JP2552006Y2 - Adjustment pedestal for civil engineering anchor - Google Patents

Description

[Detailed description of the invention]

[0001]

[Industrial application] This invention is used for earth anchor method and rock bolt anchor method of civil engineering work. When tension is applied to the anchor body after excavation work, the ground and the anchor body do not intersect vertically. Adjustment pedestal to use in case.

[0002]

2. Description of the Related Art Conventionally, an adjustment pedestal has been manufactured for each site at an assumed angle between an anchor and a ground, and the angle has been fixed.

[0003]

[Problems to be Solved by the Invention] Prevention of eccentric load when pulling the anchor, breakage of the anchor due to eccentric load, and reduction of angle adjustment time.

[0004]

SUMMARY OF THE INVENTION An inclined adjustment base 2 is provided.
When the sheets are stacked and rotated in opposite directions, the angle can be adjusted steplessly from 0 degrees to the sum of the inclination angles.

[0005]

[Operation] After the anchor body is installed and a certain curing period is set, the receiving washer, the adjusting pedestal b, the adjusting pedestal a, as shown in FIG.
Attach the washer and the tensile tester in this order.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 4, it is required that the ground and the anchor body do not intersect vertically, and most of them require adjustment. FIG. 3 shows a situation in which the adjustment angle is approaching a minimum, although it is vertical and does not require an adjustment pedestal.

[0007]

[Effect of the invention] Prevention of anchor breakage and reduction of adjustment time.

[0008] One kind of adjusting pedestal having a strength corresponding to the load may be used.

Claims (1)

(57) [Scope of request for utility model registration] 1. A civil engineering system in which two adjustment pedestals a and b with inclination are combined and rotated to rotate each other to obtain an arbitrary adjustment angle from the sum of the inclination angles of the adjustment pedestals to horizontal. Adjustment pedestal for anchor used in construction.
