Description

Self-locking anchorage device

Technical Field

The utility model belongs to the technical field of the assembly type structure connecting piece and specifically relates to a from locking-type ground tackle is related to.

Background

The anchorage device is an anchoring device applied to bridges, high-rise buildings, water conservancy and hydropower dams, rock slope protection anchoring, foundation reinforcement and tunnel mine roof anchoring. In the fabricated concrete building, connecting pieces are needed to be connected between different structural members for reinforcement, common grouting sleeve connection and blind hole grouting need to reserve construction joints, grouting is needed after mortar plugging, the construction process is complex, the construction quality is difficult to guarantee, the construction efficiency is low, and the method is uneconomical.

SUMMERY OF THE UTILITY MODEL

For solving the technical problem, the utility model provides a from locking-type ground tackle, simple structure, simple to operate does not have the wet operation in scene, has solved complicated, the inefficiency of construction, uneconomical problem.

The utility model provides a pair of from technical scheme of locking-type ground tackle is: the anchor head comprises an anchor head rod and an anchor head end part, wherein the anchor head end part is provided with a cross-shaped long groove with an inward opening; the anchor groove is internally provided with a concave part with a trapezoidal section, the upper part of the section of the concave part is narrow, the lower part of the section of the concave part is wide, and the bottom of the concave part is provided with a pointed cone which protrudes upwards.

As the utility model discloses from the improvement of locking-type ground tackle, the surface of anchor head tip has thin screw thread, anchor inslot wall is equipped with thin screw thread, the anchor head tip inserts anchor groove and anchor groove threaded connection.

The utility model discloses technical scheme is for prior art's beneficial effect:

the utility model provides a pair of from locking-type ground tackle through design anchor head and anchor groove subassembly, will during the installation the anchor head inserts the anchor groove for anchor head and ground tackle wedge inner wall are hugged closely and are agreed with, provide a simple structure, need not on-the-spot wet work, convenient operation's connecting elements for site operation, have avoided the complicated, loaded down with trivial details, the problem with high costs of construction in the traditional building.

The specific implementation mode is as follows:

the present invention will be further described with reference to the accompanying drawings and specific embodiments, but the present invention is not limited thereto.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like, indicate orientations and positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be considered as limiting the present invention.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1, a self-locking anchorage structure is shown, which comprises an anchor head 1 and an anchor groove 2.

Referring to fig. 2 and 3, the anchor head 1 includes an anchor head rod 5 and an anchor head end portion 6, and the anchor head end portion 6 is provided with a cross-shaped elongated slot 3 having an inward opening, so that the anchor head end portion 6 is divided into a shape similar to four petals.

Referring to fig. 4 and 5, the inside of the anchor groove 2 is provided with a groove 8, the cross section of the groove 8 is in a trapezoidal shape with a narrow top and a wide bottom, and the shape of the groove 8 is designed to match the shape of the anchor head end 6. The bottom of the groove 8 is provided with a pointed cone 4 which protrudes upwards. 6 surfaces of anchor head tip portion and 8 inner walls of recess all are equipped with screw thread 7, anchor

head tip portion

6 and 8 threaded connection of recess to increase friction and fastness when making both connect, anchor head 1 can not break away from anchor groove 2, reaches the auto-lock effect.

When the anchor head 1 is inserted into the anchor groove 2, namely the end part 6 of the anchor head is inserted into the groove, the anchor head rod 5 of the anchor head 1 is tapped by an instrument, and the pointed cone 4 penetrates into the cross-shaped long groove 3 with the opening at the end part of the anchor head, so that the end part 6 of the anchor head is extruded by the cone 4 from the inside to be expanded all around until the end part 6 of the anchor head is tightly attached to the inner wall of the groove 8 and is installed in place.

The self-locking anchorage device has the beneficial effects of convenience in installation during construction, no field wet operation and cost saving.
