Description
Technical field
The utility model belongs to built-in fitting field more particularly to a kind of pre-embedded bolt.
Background technology
Pre-embedded bolt also becomes foundation bolt, pre-buried, and is solid with cement in advance for fixed equipment in equipment installation
Fixed steel part.So pre-embedded bolt is pre-buried one kind, is exactly in advance that foundation bolt is prefabricated in cement base in Equipment Foundations
Among plinth, it is used for fixed equipment after solidification.Foundation bolt generally uses Q235 steel, as light to justify.Steel (Q345) intensity is big.It is right
For light circularly foot bolt, buried depth is generally 25 times of its diameter, then makees 90 degree of long crotches of 120mm or so.Such as
If very big (such as 45mm) buried depth too depth of the fruit diameter of bolt, square plate can be welded in bolt end, with such as withdrawal resistance by force effect.It buries
Deep and crotch is provided to ensure the frictional force of bolt and basis, and being unlikely to, which makes bolt generation extract, destroys.It adopts in the prior art
Used in workshop that pre-embedded bolt processed in batches is assembled, pre-embedded bolt is in Specific construction in application, being all first that building foundation is bold
It binds, is implementing pre-embedded bolt construction, but if in groups or when many bolts installation can mutually rush with field basic reinforcing bar
It is prominent, it can not construct；All it is at the construction field (site) separately with liner adjustable column furthermore when adjusting steel column height mark and verticality
Height, but difficulty of construction can be increased in this way, time-consuming and laborious, accuracy is not also high.
Utility model content
For the problems of the prior art, the utility model provides a kind of pre-embedded bolt.
One end of a kind of pre-embedded bolt, including pre-embedded bolt main body, the pre-embedded bolt main body is bent in 90 °, pre-buried spiral shell
There are two the positioning plates (adjusting backing plate) being separated at intervals for the other end installation of bolt main body, in the pre-buried of the opposite side of positioning plate
Adjusting nut is also equipped in bolt body.
Preferably, the adjusting nut is M24 fixing nuts.
Preferably, there are two the M24 fixing nuts are set in the other end close to pre-embedded bolt main body, far from pre-buried
The other end of bolt body is arranged one.
Preferably, the pre-embedded bolt main body is process using a diameter of 20mm~60mm round steel (according to different works
Journey is designed with different size requirement).
Preferably, the round steel material makes for Q235B or Q345B or specified materials.
Preferably, size length × width x thickness of the positioning plate is 80 × 80 × 20mm；The positioning plate distance is pre-
The minimum distance for burying the other end of bolt body is 60mm；The pre-buried main body is bent a length of 100mm in one end in 90 °.Institute
The distance between positioning plate stated by design requirement subject to.
Material is used to specify material to make for Q345B or Q235B or design；Single pre-buried bar is made of 1#2#3#, jointly
Effect.
Installation method：
Surveying setting-out stub reinforcing bar is bound；Stub template is installed；Positioning plate (steel plate) installation, the installation review of fixing bolt group
Bolt welding is fixed；Concrete placings, bolt review；Finished product protection
(1) axis, absolute altitude determine
(2) making of positioning plate
(3) locating template is in place
(4) installation bolt group
(5) concreting
The utility model product 1) modular in design is used, all are cut using machining, and geometric dimension is accurate, and product can
Flexibly to use；2) assembling is assembled using fixed mould bases, ensures component overall dimensions standard；3) there is particular/special requirement that entirety can be used
Galvanizing, can better corrosion resistance weather.
Pre-embedded bolt, material (q235b or q345b) is that diameter 20mm~60mm round steel is process, according to design requirement
It determines length and round steel size, effectively connection basis and steel column, both can hingedly can also be used and just connect type of attachment, there is installation
Convenient, stress is reliable, processes efficiently a variety of advantages.
Always used workshop that pre embedded bolt processed in batches is assembled in the past, engineering site is all first actually building foundation steel
Muscle is bound, then implements pre-embedded bolt construction, if installed in groups, four, and even more 90 degree of hook screw rods and live base
Plinth reinforcing bar mutually conflicts, and can not construct, and hereby, we use the single making in workshop, Assembling to greatly improve working efficiency and reality
Use feasibility.Furthermore backing plate is not adjusted with front lower place, adjusts pillar height and verticality with liner when construction, it is time-consuming and laborious, now
Increase backing plate and adjusting nut below steel column footing piece, in order to accurate, facilitate and adjust steel column height mark and verticality, change in this way
Into it is convenient accurate that construction is got up, can faster more standard reaches construction requirement.
The utility model has the beneficial effects that：The utility model is simple in structure, and operation is easy for installation；The utility model it is pre-
It buries bolt to use in the single making in workshop, Assembling, greatly improve work efficiency and practical；The utility model
Pre-embedded bolt increases on the basis of existing adjusts backing plate (i.e. positioning plate) and adjusting nut, more can accurately and easily adjust
Steel column height mark and verticality；The utility model product can effectively connect basis and steel column, and stress is reliable, using modular in design,
All, using machining cutting, can flexibly use.
