Embodiment Construction

[0028] As shown in the figure, an example of parts in the figure: a bolt that can directly enter the formation through pressure, etc., including the bolt body and the bolt head connected together, the bolt head is a cone; the cone is a cone tip or a cone Platform structure, the connection structure is that the cone is the center of the cone, the nut is connected with the anchor bolt's fine-rolled threaded steel bar, or the cone is the center of the cone, and the metal part of the cone is welded with the metal part of the anchor rod skeleton. The cross section of the cone tip or cone is a circle Or polyhedron; cone can also be made of concrete or polymer material.

[0029] Illustration: embedded nut 1-1, finished rolled steel bar 2, skeleton steel bar 3, anchor column 4, inner structure screw nut 1-2, outer ring screw nut 1-3, welding 1-4, hoop bolt locking anchor Structures 1-5, built-in flanges or nuts connect 1-6 with steel bars.

Abstract

A prefabricated prestress anchor rod with a guide device comprises prefabricated prestress anchor rod bodies and the anchor rod head guide device which are connected together. The anchor rod head guide device is a cone body. The cone body is of a cone tip or frustum structure. A connecting device for the prefabricated prestress anchor rod bodies and the cone body is shown as follows: a nut at thecenter of the cone body is connected with finished deformed bars of the anchor rod bodies, a metal part at the center of the cone body is welded to a metal part of an anchor rod framework, a connecting nut at the center of the cone body is connected with the prestress anchor rod bodies and a cone body internal rebar, the metal part at the center of the cone body is welded and connected to the prestress anchor rod bodies through flanges or rebars, the prestress anchor rod bodies and the rebars at the center of the cone body are fixed to the flanges and are connected with the two flanges throughbolts correspondingly, or two flanges with the radius larger than that of the anchor rod bodies are adopted, peripheral bolts of the two flanges are connected or the two flanges are locked through hoop bolts.

Description

technical field [0001] The invention relates to the structure and construction method of the anchor rod, especially the anchor rod does not use ready-made holes, but uses corresponding mechanical equipment, adopts static pressure method, vibration method, tamping method, spinning method and other methods to make the anchor rod Pressing into, extruding or rotating to make it self-entering into the formation structure includes the bolt components and working methods that make up the present invention. Background technique [0002] The applicant CN2020103929335 is a post-tensioning prestressing device for anchors; CN2020207414687 is a prestressed anchor with a connection structure; CN 210562163U is a prefabricated prestressed anchor member; CN2020207248475 is a prefabricated assembled anti-floating Tensile prestressed anchor, CN2020207240914, a prestressed unbonded anchor steel bar, anchor and construction method, CN2020207240755, a prestressed anchor column, anchor and constru...
