Abstract
The utility model relates to a bolt sleeve. A stud is arranged at one end of the bolt sleeve, and a bushing with internal threads is arranged at the other end of the bolt sleeve. The internal threads are matched with external threads of a foundation bolt, an anti-rust layer is arranged on the internal threads of the bushing, the upper portion of the section of the bushing is in a trapezoidal structure, and the included angle between an inclined side of a trapezoid and the horizontal line is in a range of 45 degrees to 75 degrees. External threads of the stud are identical to the external threads of the foundation bolt. The bolt sleeve has the advantages that equipment can be mounted conveniently, the structure is simple, mounting is time saving and effort saving, materials are saved, and the operation efficiency is improved.
Description
Technical field
The utility model relates to the equipment installing area, relates in particular to a kind of bolt sleeve.
Background technique
In the equipment installing area, the equipment pre-embedded anchoring bolts that runs into civil engineering through regular meeting is too short, and causing machinery to be installed can't construct.Traditional processing method is the basis that chisels out civil engineering, bury bolt again underground after formwork beat ash.This method wastes time and energy, and influences construction progress.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model provides a kind of bolt sleeve, and is simple in structure, and it is time saving and energy saving to install, and improves operating efficiency.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of bolt sleeve, described bolt sleeve one end is provided with double-screw bolt, the other end is provided with the sleeve pipe that has internal thread, internal thread cooperates with the outside thread of stone bolt, the sleeve pipe internal thread is provided with resin layer, the casing profile shaped upper part is trapezium structure, and trapezoidal hypotenuse and horizontal line angle are 45～75 degree, and described double-screw bolt outside thread is identical with the stone bolt outside thread.
Described resin layer thickness is 0.5mm～3mm.
Compared with prior art, the beneficial effects of the utility model are:
Make things convenient for equipment to install, simple in structure, it is time saving and energy saving to install, and saves material, improves operating efficiency; Resin layer can prolong the working life of stone bolt.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the casing profile structural representation.
Fig. 3 is the utility model mounting structure schematic representation.
Among the figure: 1-double-screw bolt 2-internal thread 3-back-grouting 4-equipment bay 5-foundation of civil work 6-stone bolt 7-resin layer 8-trapezium structure.
Embodiment
Below in conjunction with Figure of description the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following mode of execution.
See Fig. 1, Fig. 2 and Fig. 3, a kind of bolt sleeve, this bolt sleeve one end is provided with double-screw bolt 1, the other end is provided with the sleeve pipe that has internal thread 2, internal thread 2 cooperates with the outside thread of stone bolt 6, and sleeve pipe internal thread 2 is provided with resin layer 7, and the casing profile shaped upper part is trapezium structure 8, trapezoidal hypotenuse and horizontal line angle are 45～75 degree, and described double-screw bolt 1 outside thread is identical with stone bolt 6 outside threads.
Described resin layer 7 thickness are 0.5mm～3mm.
During making, use round steel processing identical with stone bolt 6 materials or foot bolt 6 intensity above Ground, require outside thread and the stone bolt 6 outside thread parameters of double-screw bolt 1 identical, an end length that has internal thread 2 should make the installation absolute altitude (put bolt sleeve after do not influence the absolute altitude of equipment bay 4 bottom surfaces) of tight top absolute altitude behind the stone bolt 6 that is located at foundation of civil work 5 less than equipment bay 4 bottom surfaces under the condition that is satisfying requirement of strength.
The sleeve pipe of bolt sleeve one end is tightened on the stone bolt 6, guarantee that the top absolute altitude is less than the installation absolute altitude of equipment bay 4 bottom surfaces, because internal thread 2 is provided with resin layer 7, avoids stone bolt 6 and bolt sleeve corrosion, prolong the working life of stone bolt 6 and bolt sleeve.Carrying out back-grouting 3 then, because bolt sleeve is provided with trapezium structure 8, can make more firm the imbedding in the grouting 3 of bolt sleeve, is mountable device base plate 4 after waiting grouting to parch.
The utility model makes things convenient for equipment to install, and simple in structure, it is time saving and energy saving to install, and saves material, improves operating efficiency; Resin layer can prolong the working life of stone bolt.
