Abstract
A kind of stud extender device is made of threaded rod, matching nut, gasket；Length L=2b+c+d of the threaded rod；B-matching nut thickness, unit mm；Exposed length, unit mm after c-threaded rod fastening；D-spacer thickness, unit mm；One end of the threaded rod is equipped with interior hexagonal groove, is used for die nut fastening screw, and the other end of threaded rod is equipped with threaded hole matched with pre-embedded bolt, and screw thread hole depth is a >=pre-embedded bolt protruded length-plant bottom case or base plate thickness.The present invention solves the problems, such as that pre-embedded bolt falls short of.
Description
Technical field
The invention belongs to environment protection fields, and in particular to a kind of stud extender device, when pre-embedded bolt leakage length is inadequate,
The defect that this device makes up curtailment can be used, it is easy for installation, it is economic and practical.
Background technique
Most of large scale equipment or steel construction in a pre-installation, can all shift to an earlier date pre-embedded bolt and plant bottom case on foundation
Or steel construction bottom plate is bolted, but pre-embedded bolt construction when construction error or design fault etc. due to, can go out
The inadequate situation of the protruded length of existing pre-embedded bolt, cannot correctly be installed by drawing, the later period is caused security risk occur.
When the inadequate situation of the protruded length for encountering pre-embedded bolt, common several treating methods have:
1 is directed to the installation of important equipment, it is desirable that does basis again, again pre-embedded bolt, will cause the delay of duration in this way, cause
The waste of lot of materials and fund.
2 excision bolts, lay bolt using the method that chemistry plants bolt again, this method need to through a large amount of accounting of designing institute,
The live transformation in original basis, installation accuracy can also decline simultaneously, and there are certain security risks.
Surface layer's concrete is dug out a part, then slices off a part of pre-embedded bolt by 3 common methods, then will be prepared again
The bolt welding of spreading after connecting, is then again filled concrete absolute altitude to institute with high-intensitive pea gravel concreten grouting to connecting
Need absolute altitude.This method complex procedures, required precision is high, equally will cause the delay of duration, causes the wave of lot of materials and fund
Take.
Summary of the invention
In order to solve the problems, such as that pre-embedded bolt falls short of, the purpose of the present invention is intended to provide a kind of safe and reliable one of structure
Kind stud extender device, it not only will not influence the precision of post facility installation, will not cause the wave of lot of materials and fund
Take, it is ensured that therefore will not influence project progress.
The present invention is a kind of stud extender device, by the pre-embedded bolt spreading that protruded length is inadequate, then screws on nut fastening,
It will not have any impact to the installation of plant bottom case and steel construction bottom plate, original installation accuracy will not be influenced,
A kind of stud extender device is made of threaded rod, matching nut, gasket.
Length L=2b+c+d of the threaded rod,
B-matching nut thickness, unit mm；
Exposed length, unit mm after c-threaded rod fastening；
D-spacer thickness, unit mm；
One end of the threaded rod is equipped with interior hexagonal groove, is used for die nut fastening screw, the other end of threaded rod be equipped with
The matched threaded hole of pre-embedded bolt, screw thread hole depth are a >=pre-embedded bolt protruded length-plant bottom case or base plate thickness.
Stud extender device occurs to make in advance when protruded length is inadequate in discovery foundation built-in bolt, surveys by scene
Amount data determine the size of length sleeve L and depth of internal thread a, are dealt into scene after completing.Scene first by plant bottom case or
Steel construction bottom plate navigates on foundation built-in bolt, then stud extender device internal thread side and pre-embedded bolt is mating stubborn
On, there is the side of interior hexagonal that stud extender device is fastened on each pre-embedded bolt using allen wrench in stud extender device
On, then successively gasket, double nut are mounted on stud extender device, as required by the plant bottom case adjusted or steel construction bottom
Plate finally tightens fixation.
The present invention solves the problems, such as that pre-embedded bolt falls short of.When the foundation built-in bolt protruded length of equipment or steel construction not
When enough, foundation built-in bolt can be lengthened using the present invention, the basis without being ready for scene is done at any transformation
Reason, saves a large amount of people, machine, material and time, ensure that construction speed, while the fastening to plant bottom case or steel construction bottom plate
Intensity will not generate any influence.
Detailed description of the invention:
Fig. 1 is usage state diagram of the invention.
Fig. 2 is the structure chart of threaded rod in the present invention.
Fig. 3 is the top view of Fig. 2.
In figure, 1, basis, 2, pre-embedded bolt, 3, plant bottom case or steel construction bottom plate, 4, gasket, 5, matching nut, 6, spiral shell
Rasp bar, 7, threaded hole, 8, interior hexagonal groove, 9, external screw thread.
Specific embodiment
A certain bulk cargo stockyard, prevents flour dust overflow, pollutes to surrounding enviroment, need to build steel construction in stockyard surrounding and enclose
Engineering is kept off, after engineering foundation completion, carries out finding there is the pre-embedded bolt protruded length of part basis in process handover inspection
Not enough, such as the part basis is transformed again, not only results in the waste of resource, while can take a substantial amount of time, it will certainly
The installation of later period steel bracket is influenced, to guarantee construction period, needs producer that other methods is taken to handle.
Stud extender device can be used in the case of this, and the length L and screw thread of threaded rod are determined according to field measurement data
The depth a in hole, is dealt into scene after completing as required, scene is installed.
Step 1: the steel bracket made in advance to be first lifted into the position of corresponding foundation built-in bolt, steel branch is adjusted
The verticality and levelness of frame bottom plate.
Step 2: there is one end of threaded hole to be screwed on pre-embedded bolt with allen wrench the threaded rod made in advance,
Preliminary fixed steel bracket bottom plate.
Step 3: finally screwing on nut in the outer sheath Upper gasket of threaded rod and compressing steel bracket bottom plate.
Complete the installation of entire steel bracket.
Shown in Fig. 1, a kind of stud extender device is made of threaded rod 6, matching nut 5, gasket 4.
Length L=2b+c+d of the threaded rod,
B-matching nut thickness, unit mm；
Exposed length, unit mm after c-threaded rod fastening；
D-spacer thickness, unit mm.
Shown in Fig. 2, one end of the threaded rod is equipped with interior hexagonal groove 8, and the other end of threaded rod is equipped with and pre-embedded bolt
Matched threaded hole 7, screw thread hole depth are a >=pre-embedded bolt protruded length-plant bottom case or base plate thickness.
