Embodiment Construction

[0032] The content of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] The nail nut is composed of the nail cap of the nail nut, the nail rod of the nail nut and the internal thread of the body, the nail cap of the nail nut, the nail rod of the nail nut and the internal thread of the body. processed into a whole. The thread on the nail nut is machined into an internal thread, and the pitch matches the embedded bolt. The shape of the screw nut is processed into a screw. The diameter of the screw cap of the screw nut is larger than the diameter of the screw rod of the screw nut. The effective cross-sectional area of ​​the screw rod of the screw nut is larger than the cross-sectional area of ​​the embedded bolt. The nail cap is machined into a hexagon. There are two connection methods for the nail nut. The first connection method is: the nail rod of the nail nut passes through the steel plate ...

Abstract

The invention discloses a communal nail-shaped screw cap for the base of a crane and the use method of the communal nail-shaped screw cap. The communal nail-shaped screw cap is mainly used for mounting the base of the crane for building construction, and belongs to the technical field of building construction. The communal nail-shaped screw cap adopts the main technical scheme that the nail-shaped screw cap is composed of a nail cap, a nail rod and an inner threaded hole, wherein the nail cap, the nail rod and the inner threaded hole are processed into a whole, the thread pitches of the inner threaded hole are matched with those of a pre-buried bolt, and the diameter of the nail cap is larger than the diameter of the nail rod. The nail-shaped screw cap is convenient for mounting and demounting the crane on a construction site, the time for treating the displacement of the pre-buried bolt is shortened, and the construction period for mounting construction is ensured; the cost for handling the displacement of the pre-buried bolt can be effectively lowered; except for crane equipment for construction, the communal nail-shaped screw cap also can be used for pre-buried bolts on large scale power equipment in workshops, industrial buildings, experimental bases and the like, or sites where bolts or screws are inconvenient to replace, and has universality.

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...
