Embodiment Construction
[0032] The content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0033] The nail nut is made up of the nail cap of the nail nut, the shank of the nail nut and the internal thread of the body, the nail cap of the nail nut, the nail shank of the nail nut and the internal thread of the body processed into a whole. The thread on the nail-shaped nut is processed into an internal thread, and the pitch matches the embedded bolt. The shape of the nail-shaped nut is processed into a screw. The diameter of the nail-shaped nut is larger than the diameter of the shank of the nail-shaped nut. The effective cross-sectional area of the nail-shaped nut is larger than that of the embedded bolt. The nail cap is processed into a hexagon. There are two ways to connect the nail-shaped nut. The first connection method is: the nail rod of the nail-shaped nut passes through the steel plate gasket, the foundatio...

The invention discloses a common nail-shaped nut for crane foundations and usage thereof, which is mainly used for the installation of crane foundations for building construction and belongs to the technical field of building construction. The main technical scheme is: the nail-shaped nut is composed of a nail cap, a nail shank and an internally threaded hole. The nail cap, nail shank and the internally threaded hole are processed into a whole. The diameter is greater than the diameter of the nail shank. The nail-shaped nut facilitates the installation and removal of the crane on the construction site, shortens the time for dealing with the displacement of embedded bolts, and ensures the construction period of equipment installation and construction; effectively reduces the cost of dealing with the displacement of embedded bolts; in addition to being used for construction In addition to lifting machinery and equipment, it can also be used in workshops, workshops, experimental bases, etc., as embedded bolts for large power equipment, or in places where it is inconvenient to replace bolts or screws, and has versatility.
Description
technical field [0001] The invention discloses a common spike nut for crane foundations and usage thereof, in particular to a common spike nut for crane foundations on a construction site, which is mainly used for the installation of crane foundations for building construction and belongs to the technical field of building construction. Background technique [0002] The hoisting machinery widely used on construction sites is an important equipment for construction hoisting and transportation operations in the construction industry. Most of the vertical transportation of building materials is completed by it. Whether the hoisting machinery can operate normally will directly affect Construction safety, quality, schedule and cost control. Due to the large number of various lifting machinery and equipment used on the super-large-scale engineering project site of our construction (only 255 sets of tower cranes) and many specifications, various foundation pre-embedded facilities a...
