Abstract
A lifting tool for lifting large and long stone column is composed of a U-shaped fastener, a screw bolt, a nut, and a pre-embedded plate group consisting of a group of filling plates and locking plates arranged at both sides of said filling plate group. Said pre-embedded plate group is pre-embedded in the top end of said large and long stone column. Its top end has a through hole for connecting said U-shaped fastener via screw bolt and nut.
Description
(1) technical field
The present invention relates to the trapezoidal suspension hook of hoisting large and long stone column, be applicable to that the lifting lifting greatly enhances the occasion of hoisting engineerings such as stone column.
(2) background technology
Before the present invention makes, existing lifting lifting greatly enhances the stone column suspension hook and is attached on the hoisting crane, can only be realized lifting by the rope of hoisting large and long stone column by colligation, really, the suspension hook of this structure is only applicable to the lifting of corpusculum amount stone column, and generally all for tiltedly hanging, difficultly directly hang accomplishing, be difficult to carry out the aligning that greatly enhances the stone column installation process, in place.Because greatly enhance that stone column deadweight is big, volume is big, lifting moment is big, frangibility and feature such as easily cracked, the colligation hoisting process is aimed at quite difficulty in place.
(3) summary of the invention
The objective of the invention is to solve that existing suspension hook is difficult directly hangs accomplishing, be difficult to carry out greatly enhance in the stone column installation process aim at, shortcoming in place, provide a kind of pre-buried group is embedded in the top that greatly enhances stone column before implementing lifting, utilize pre-buried group and implemented lifting, thereby improve the hook for hoisting large and long stone that greatly enhances Aligning degree, accuracy in the stone column installation process by friction force between lifting components and shearing force.
For this reason, the present invention is by the following technical solutions:
A kind of hook for hoisting large and long stone, include U-shaped snap ring, screw rod, nut, described U-shaped snap ring two ends are provided with the snap ring through hole that cooperates with screw rod, also comprise pre-buried group, described pre-buried group includes filler piece and locking plate, some filler pieces are arranged together successively forms the filler piece group, and described filler piece group both sides are arranged described locking plate respectively; The bottom of described locking plate is provided with the locking part of evagination; The filler piece of pre-buried group of described formation, the top of locking plate have through hole, and described pre-buried group is fixed tightly in the snap ring by screw rod that runs through through hole and the nut that cooperates with screw rod.
The lower end of described pre-buried group at grade.
The cross section of the locking part of described locking plate is trapezoidal.
Employing the present invention have the following advantages: the hoisting large and long stone column is embedded in the top that greatly enhances stone column with pre-buried group of suspension hook with trapezoidal suspension hook before implementing lifting, utilize pre-buried group and implemented lifting, improved the aligning that greatly enhances the stone column installation process, accuracy in place by friction force between Lift hook spare and shearing force; Remedy prior art and can't realize greatly enhancing accurately deficiency in place of stone column hoisting process, and simple structure, used easy to operately, had bigger practical value and economic results in society.
(4) description of drawings
Fig. 1 is a structural representation of the present invention.
(5) specific embodiment
A kind of hook for hoisting large and long stone includes U-shaped snap ring 1, screw rod 2, nut 3, pre-buried group; Described pre-buried group comprises filler piece 4 and locking plate 5, and some filler pieces are arranged together successively forms the filler piece group, and described filler piece group both sides are arranged described locking plate respectively; The bottom of described locking plate is provided with the locking part 6 of evagination; The filler piece of pre-buried group of described formation, the top of locking plate have the installation through hole, described snap ring two ends are provided with the snap ring through hole, and described pre-buried group is fixed tightly in the snap ring by running through the installation through hole and the screw rod of snap ring through hole and the nut that cooperates with screw rod.The lower end of described pre-buried group at grade.The cross section of the locking part of described locking plate is trapezoidal.
Concrete algorithm: greatly enhanced stone column according to hanging,, determine the size and the quantity of filler piece at last through computational analysis by the data analysis shearing strength value that test obtains; And the size of snap ring, the size of screw rod; Earlier greatly enhance the stone column upper end and open one and the pre-buried up-small and down-big trapezoidal hole that group lower end shape is complementary being hung, before the lifting locking plate of pre-buried group both sides is put earlier, order is from big to small filled in remaining filler piece again, make pre-buried group and quilt be hung jam-pack between member, set up snap ring then, load onto screw rod, nut, prepare lifting.Suspension hook of the present invention is reusable, and disassembly sequence is opposite with sequence of erection.
Claims (3)
1. hook for hoisting large and long stone, include U-shaped snap ring, screw rod, nut, described U-shaped snap ring two ends are provided with the snap ring through hole that cooperates with screw rod, it is characterized in that: also comprise pre-buried group, described pre-buried group includes filler piece and locking plate, some filler pieces are arranged together successively forms the filler piece group, and described filler piece group both sides are furnished with locking plate respectively;
