Description
Technical field
The utility model belongs to Construction for Hydroelectric Project mechanical equipment technical field, and in particular to a kind of two-part elevator
Machine basis pre embedded bolt.
Background technology
Using telescoping steel form pour tunnel side-top arch concrete with mechanization degree is high, speed of application is fast, concrete into
The advantages that type quality is good, thus telescoping steel form hydraulic and hydroelectric engineering tunnel concrete liner construction in obtained it is relatively broad
Using.
The walking of telescoping steel form is using self-driving type or passively draws two schemes, for the construction portion that tunnel longitudinal slope is larger
Position, it is general using passive traction walking scheme.The corrosion of embedded iron parts later stage causes destroying concrete structure, water conservancy water in order to prevent
Electrical engineering proposes higher quality requirement to the underplate concrete surface of water tunnel.According to conventional construction scheme, use is general
When leading to built-in connection of the screw rod as telescoping steel form rack winch basis, the construction later stage needs to cut pre embedded bolt
Repairing treatment is carried out with backfill epoxy-like materials.
The content of the invention
The utility model uses built-in connection of the common screw as telescoping steel form rack winch basis to overcome
The defects of being caused to concrete surface results in the need for the later stage using epoxy material progress defect mending problem, provides one kind two
Segmentation hoist engine basis pre embedded bolt device.
The technical solution of the utility model is：Hoist engine basis pre embedded bolt main body be two-part screw rod, first segment screw rod
It is provided with the structure reinforcing bars arranged in anchoring crotch and underplate concrete to be welded and fixed, first segment screw rod is by connecting tapered sleeve and the
Two stage screw connects, and the other end and the hoist engine pedestal of second segment screw rod are welded and fixed.
The two-part hoist engine basis a diameter of 32mm of pre embedded bolt, the total length of two sections of screw rods is 166cm, wherein
First segment spiro rod length 116cm（The long 20cm of crotch）It can be adjusted according to base arrangement Concrete Design thickness；Second segment spiral shell
Pole length is 50cm.
Steel connection the tapered sleeve length 120mm, tapered sleeve internal diameter 30mm, maximum outside diameter 85mm；Tapered sleeve installation suitable for reading is high
Journey is flushed with underplate concrete surface.
The utility model has the advantage that first, simple in structure, installation and removal are easy to use, avoid using pre-buried general
The mass defect problem that logical bolt scheme brings concrete surface, improves Surface Quality of Concrete；Second is that the utility model
Installation cost is relatively low, connects the recyclable reuse of tapered sleeve, effectively reduces later stage reinforcement of concrete defect expense.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment

In figure：1-first segment screw rod, 2- second segment screw rods, 3- connection tapered sleeves, 4- hoist engines, 5- have poured the bottom of completion
Board concrete, 6- base arrangement reinforcing bars.
Specific embodiment
As shown in Figure 1, the two-part hoist engine basis pre embedded bolt main body of the utility model is two-part screw rod, first segment
Screw rod 1 is provided with anchoring crotch and the base arrangement reinforcing bar 6 of arrangement in concrete is welded and fixed, and first segment screw rod 1 passes through connection
Tapered sleeve 3 is connected with second segment screw rod 2, the other end of second segment screw rod 2（Exposed junction）It is welded and fixed with hoist engine pedestal.
The two-part hoist engine basis a diameter of 32mm of pre embedded bolt, is Q235 steel screw rods, two sections of screw rods it is total
Length is 166cm, wherein first segment spiro rod length 116cm（The long 20cm of crotch）Can according to base arrangement Concrete Design thickness into
Row adjustment；Second segment spiro rod length is 50cm.
The steel connection tapered sleeve is detachable, using Q235 steel, length 120mm, tapered sleeve internal diameter 30mm, maximum outside diameter
85mm；Tapered sleeve Installation Elevation suitable for reading is flushed with underplate concrete surface.
Operating process：
The good first segment screw rod 1 of processing and fabricating, second segment screw rod 2 are connected tapered sleeve 3 by steel and complete to assemble first, so
The bent hook part of first segment screw rod 1 and underplate concrete structure reinforcing bars 6 are welded and fixed afterwards, the pre embedded bolt connection cone after installation
Covering 3 elevations suitable for reading should be with the underplate concrete flush of design.Underplate concrete 5, which pours, to be completed and reaches after some strength i.e.
Hoist engine pedestal 4 and 2 revealed section of second segment screw rod can be welded and fixed, so as to complete the installation of telescoping steel form rack winch.
The fixation that gas cutting mode releases hoist engine pedestal 4 and second segment screw rod 2 can be used after telescoping steel form end of run, then use and pull
Hand dismounting second segment screw rod 2 connects tapered sleeve 3 with steel；Taper sleeve hole is backfilled using pre contract mortar.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations；The common skill of this field
Art personnel should be understood：It can still modify to the technical solution recorded in foregoing embodiments or to its middle part
Technical characteristic is divided to carry out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is not made to depart from this practicality
The spirit and scope of new each embodiment technical solution.
