Description

Pre-embedded bolt group locator
Technical field
The utility model relates to a kind of locator, relates in particular to a kind of pre-embedded bolt group locator.
Background technology
In China's construction work now, main equipment, steel structure column etc. are installed increasing.In order to go up being regularly connected of plant equipment or steel structure column and foundation, need to be in building engineering construction pre-embedded anchoring bolts group.The pre-buried installation accuracy that requires of stone bolt group is high, in pre-embedded anchoring bolts construction, need each root stone bolt accurately to locate, in concreting process, also need to maintain not change of relative position, inclination, torsion etc. between bolt, and national regulation and industry standard and designing requirement higher to pre-embedded bolt group position accuracy demand, if do not adopt appropriate Bolt positioner, cannot realize quality specifications requirement, also because of complicated construction technique, long in time limit, and labor intensive is high.
Existing pre-embedded bolt group's location adopts two kinds of forms conventionally: single-deck positioner and double plate positioner, but all there are many technological deficiencies in these two kinds of positioners, cannot meet the requirement of quality specifications.
1, traditional single-deck positioner adopts a steel disc as horizontal location dish, positioning disk is provided with locating hole, each bolt of pre-embedded bolt group screws in respectively the locating hole penetrating on disk after nut and stretches out screw rod, screw in again nut, nut by location-plate upper and lower surface compresses positioning disk, and pre-embedded bolt is fixed.The length of stretching out locating hole due to common pre-embedded bolt is larger, while adopting this locate mode to construct, can only be to Bolt Relatively orientation, and can not ensure that the axis between pre-embedded bolt does not change.Pre-embedded bolt also easily reverses and out of plumb ground, greatly affects the installation of Bolt superstructure or equipment, causes difficulty of construction to strengthen, and workmanship is difficult to ensure.
2, double plate positioner is the improvement on traditional single-deck positioner, which adopts by two steel disc as horizontal location dish, on two positioning disks, be respectively equipped with corresponding locating hole, pre-embedded bolt passes after two positioning disks, then is undertaken fastening by the nut of positioning disk upper and lower surface.Owing to adopting double disk structure, axial line distance between pre-embedded bolt can be determined jointly by the locating hole between upper and lower two positioning disks, compare with traditional single-deck location, though which can ensure that between pre-embedded bolt, axial line distance does not change, but still can there is the situation that pre-embedded bolt group reverses in the same direction, cause equally and reverse and out of plumb ground, this device has increased the consumption of material, the working strength that has increased workman, has improved construction cost, has also reduced speed of application simultaneously.
Summary of the invention
Based on this, the utility model is to overcome the defect of prior art, a kind of pre-embedded bolt group locator is provided, this pre-embedded bolt group locator can carry out comparatively accurate positioning control to the axial location of pre-embedded bolt and verticality, be conducive to guarantee workmanship, and use easy to operately, can improve installation effectiveness.
Its technical scheme is as follows:
A kind of pre-embedded bolt group locator, comprise that bolt shaft is apart from positioning disk, this bolt shaft is provided with multiple locating holes apart from positioning disk, and bolt shaft is fixedly installed the cylindrical sleeves consistent with described locating hole quantity on positioning disk, cylindrical sleeves communicates with corresponding locating hole, and cylindrical sleeves and described bolt shaft perpendicular apart from the card of positioning disk.
When use, pre-embedded bolt is passed to locating hole and cylindrical sleeves, adjust the height of pre-embedded bolt, and the hold-down nut that use matches with pre-embedded bolt is locked towards the two ends of cylindrical sleeves, then by the bottom of pre-embedded bolt and reinforced concrete structure not yet the steel bar welding of concreting be connected into an entirety and fix, finally carry out again concreting, complete construction.Because cylindrical sleeves communicates with corresponding locating hole, and cylindrical sleeves and bolt shaft are perpendicular apart from positioning disk, thereby only need be by pre-embedded bolt through after locating hole and cylindrical sleeves and be fixed, can guarantee the relative position of each pre-embedded bolt, the more important thing is, can ensure thus bolt verticality, axial location, absolute altitude and relative size accurately, reach the object of controlling pre-embedded bolt accuracy, thereby can ensure construction quality, reduce and proofread and correct the difficulty of repairing or adjusting.And the accurate location that can guarantee pre-embedded bolt due to this pre-embedded bolt group locator makes pre-embedded bolt can not twist and be not orthogonal to the situation on ground, thereby also helps saving construction material, reduce construction cost.In addition, this pre-embedded bolt group locator uses easy to operate, is conducive to reduce workman's labour intensity and improves efficiency of construction.
In an embodiment, described cylindrical sleeves is all arranged on described bolt shaft the same side apart from positioning disk therein.Thereby, this pre-embedded bolt group locator is used more convenient to operate, be more conducive to construct.
In an embodiment, described bolt shaft is central axis symmetric shape apart from positioning disk therein, makes this bolt shaft have the central axis perpendicular with its card apart from positioning disk, and the plurality of locating hole uniformly-spaced arranges around described central axis.Thereby pre-embedded bolt uniformly-spaced arranges around described central axis, be conducive to guarantee workmanship.
In an embodiment, described bolt shaft is provided with hollow hole apart from the middle position of positioning disk therein.Thereby, be conducive to reduce the weight of this pre-embedded bolt group locator, with convenient construction.
In an embodiment, the internal diameter of described cylindrical sleeves is consistent with the aperture of described locating hole therein.Thereby, be conducive to guarantee to better location and installation of pre-embedded bolt.
In an embodiment, the internal diameter of described cylindrical sleeves is than the large 2.5-3.5mm of the diameter of described pre-embedded bolt therein.Thereby, guaranteeing that pre-embedded bolt can pass under the prerequisite of locating hole and cylindrical sleeves, can guarantee that this pre-embedded bolt group locator carries out comparatively accurate location and installation to verticality and the axial location etc. of pre-embedded bolt, constructs with fast and easy.
Therein in an embodiment, pre-embedded bolt exposes the short 28-32mm of height on this cylindrical sleeves top described in the Length Ratio of described cylindrical sleeves.Nut screws in the head portion that this pre-embedded bolt exposes cylindrical sleeves, can effectively protect the thread on this pre-embedded bolt, and in addition, the Design of length of this cylindrical sleeves can also be conducive to improve installation rate, and guarantees construction quality.
Therein in an embodiment, described cylindrical sleeves and described bolt shaft are apart from perpendicular between positioning disk and be connected by freezing.Thereby, make cylindrical sleeves can be fixedly installed on bolt shaft on positioning disk, and communicate with described locating hole.
The beneficial effects of the utility model are:
(1) pre-embedded bolt group locator of the present utility model can be guaranteed the accurate location of verticality, axial location, absolute altitude and relative size etc. to pre-embedded bolt, thereby can guarantee workmanship.
(2) pre-embedded bolt group locator of the present utility model is conducive to save construction material, reduces construction cost.
(3) pre-embedded bolt group locator use of the present utility model is easy to operate, is conducive to reduce workman's labour intensity and improves efficiency of construction.
