Description
Technical field
The invention belongs to construction technology of cast-in-place bored field, in particular to a kind of reinforced concrete bored pile reinforcing bar
Cage automatic butt jointing device and interconnection method.
Background technique
Deposited reinforced concrete pile is now widely used for the ground of building construction, railway, highway bridge and culvert and municipal works
It handles in engineering, deposited reinforced concrete pile used by wherein railway, highway and municipal bridges and culverts design has that a diameter is big, main reinforcement is straight
The features such as diameter is big and reinforcing bar is closeer, pile body is long gives steel reinforcement cage so the weight and length of molding steel reinforcement cage of producing once are larger
Once mounting causes very big difficulty in place, and security risk when lifting is big, therefore it is general to construct for longer steel reinforcement cage
Using merogenesis production, carry out in steel reinforcement cage decentralization process docking it is assembled by the way of.20mm is greater than for steel reinforcement cage main reinforcement diameter
Steel bar connector, design and job specfication generally requires using be mechanically connected and weld form.The reinforcing bar of merogenesis production
Cage docking uses rolling straight thread docking sleeve construction technology, than works such as flash butt welding, electroslag pressure welding, other machinery connections
Skill has many advantages, such as that easy to operate, speed of application is fast, quality is easily guaranteed that, is not influenced by winter low temperature, construction economy is profitable,
So there is good application prospect.
The docking of steel reinforcement cage is always to perplex a problem of unit in charge of construction in pile foundation construction, and steel reinforcement cage docking time is general
Account for 70%~80% or so of cage time under entire steel reinforcement cage, thus the docking speed of steel reinforcement cage directly influence lower cage when
Between, area especially bad in some geological conditions threatens the quality of pile.
Existing steel reinforcement cage not can guarantee upper and lower section steel reinforcement cage and connect the upper and lower to level of reinforcing bar afterwards in place in docking
Really, often there is deviation, while also not can guarantee the corresponding every steel bar end of upper and lower section steel reinforcement cage and being close to, in section steel above and below
Muscle cage inevitably will appear between the upper and lower end of local reinforcing bar that there are gaps when docking, to make being engaged for screw thread steel and sleeve
Length is reduced, and is weakened the bonding strength of joint, not can guarantee joint quality, and ought save the connection steel of steel reinforcement cage above and below
When muscle contraposition inaccuracy, it is cumbersome to will also result in worker's execute-in-place, and time-consuming and laborious, docking speed is slow, to affect pile foundation
Speed of application.
