Problems solved by technology

Although the anti-floating anchor assembly adopts a structure with an enlarged end, the structural design of the anchor head is too complicated, and the end is enlarged without reinforcement, which may easily cause the end to break and reduce the pullout resistance of the anchor

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0026] Such as figure 1 As shown, it is a structural schematic diagram of an embodiment of the end enlarged anti-floating anchor rod of the present invention. The end enlarged anti-floating anchor rod of this embodiment includes an anchor rod 1 and an anchor head arranged at the bottom of the anchor rod 1, and an end enlargement structure is provided on the anchor head. The end enlargement structure of this embodiment includes a bottom plate 2 fixedly connected to the bottom of the anchor rod 1 and a connecting plate 3 arranged uniformly in a ring and welded to the bottom plate 2 and the anchor rod 1 at the same time. The connecting plate 3 is provided with a connecting hole 4. T...

Abstract

The invention discloses an end expanding type anti-floating anchor rod. The end expanding type anti-floating anchor rod comprises an anchor rod body and an anchor head arranged at the bottom of the anchor rod. The anchor head is provided with an end expanding structure. The end expanding structure comprises a bottom plate fixedly connected with the bottom end of the anchor rod body, and connecting plates which are annularly distributed evenly and fixed with the bottom plate and the anchor rod body in a welding manner. The connecting plates are provided with connecting holes. The connecting holes are provided with an expanding frame with one end hinged to the connecting holes. A through hole is formed in the other end of the expanding frame. The through hole of the expanding frame is internally provided with a telescopic connecting line. The two ends of the connecting line are connected into a whole. According to the end expanding type anti-floating anchor rod, the pulling resistance and the anti-shearing strength between the anchor rod body and rock and soil can be improved. The end expanding type anti-floating anchor rod has the beneficial effects of being simple in structure and convenient to machine, construct and install.

Description

technical field [0001] The invention belongs to the technical field of anchoring structural components in building construction technology, and in particular relates to an anti-floating anchor rod with enlarged end. Background technique [0002] With the development of cities and the continuous reduction of construction land, people are using more and more underground space. The construction of a large number of high-rise buildings with basements, underground garages, sunken squares, subways, underground shopping malls and other underground buildings (structures) has made the problem of anti-floating very prominent. Especially in cities with abundant underground water table, if the self-weight of the structure is less than the buoyancy force, the bottom plate of the structure will be arched and cracked under the action of the buoyancy force, and the structure will eventually be damaged, which will affect the use. [0003] The Chinese patent whose publication number is CN202...
