Description
Technical field
This utility model relates to a kind of steel bar connecting sleeve of fabricated constructional member of reinforced concrete member.
Background technology
Build to manufacturing in transition process in traditional architecture industry, have many key technologies to need to break through and innovation, significantly rebar connecting technology.Rebar connecting technology is called one of ten big new techniques in building industry.Building is disassembled into component by assembled architecture exactly, transports to building-site and carry out lifting assembly after factory process.Component is exactly main contents of the present utility model with the bar connecting of component in the process.The bar connecting of component and component is at same section parts and is the critical core region of structure stress, so rebar connecting technology product conventional on existing market can not be suitable for, also have some technical products from being abroad introduced through improvement or Shortcomings and cost high phenomenon.Such as
1 is mechanically connected the deficiency that sleeve exists: reinforcing bar mechanical sleeves is connected in existing Construction Mode to be the most commonly used technology, and its product quality is also reliable and stable.Then held in both hands by rotation bar connecting during site operation and be bundled into the last casting concrete of cage.Being that component is connected with component in assembled build model, be under the immotile premise of reinforcing bar and be attached, and be that many reinforcing bars connect in same cross section, it is inapplicable that this technical products does not just possess such function.
2 deficiencies being welded to connect existence: reinforcement welding is connected to various ways (two-sided welding, single-sided welding, docking welding) etc., is unallowed at same cross section bar connecting in existing industry standard.And high temperature can produce material and becomes and affect the intensity of reinforcing bar when welding.
3 sleeve slip castings connect the deficiency existed: it is that domestic and international prefabricated components bar connecting popularizes conventional technical products that sleeve slip casting connects, it is the middle part that bar connecting point is arranged on sleeve that sleeve slip casting connects, component is first fixed during construction, after closing gap, pressure fills high intensity slurry, carries out lower road flow chart most until the slurry that pressure fills reaches some strength.It is proven and produces following deficiency in this case:
The concrete effective protection aquiclude of the big impact of A sleeve diameter, at present conventional processing method 1 strengthens sectional dimension of members and causes concrete amount to increase and the series of problems that produces.2 reinforcement locations are mobile in component causes behavior of members under loading to weaken.
B slip casting length sleeve length affects the installation of stirrup, and component is generally connected at crux node region with component, and in this region, stirrup needs encryption, and the installation that therefore can affect stirrup causes connection node stress performance to weaken.
C component at the construction field (site) is installed after positioning again by component firm supporting, and rear closure slip casting region waits that plugging material has during intensity and is irrigated slurry most, reaches to carry out most after some strength the construction of lower road flow chart until slurry.So causing difficulty of construction to increase, speed of application such as slows down at the problem.
D slip casting is it is necessary to have professional's operation, and building-site complexity likely can cause some position slip casting inconvenient and cause slip casting leakiness, and whether slip casting is closely knit at the scene also without detection means.So cause and occur that carelessness just has no idea to make up during slip casting, have a strong impact on bar connecting quality.
The deficiency that 4 Bar Anchorage overlap joints exist: reserving hole in prefabricated components, connect reinforcing bar and stretch out outside component, closure slip casting region after lifting para-position at the scene, waits that plugging material has during intensity and is irrigated slurry most, reaches to carry out most after some strength the construction of lower road flow chart until slurry.So causing difficulty of construction to increase, speed of application such as slows down at the problem.
Summary of the invention
This utility model is for the deficiencies in the prior art, it is provided that one effectively prevents axial compressive force, improves bonding strength, and can realize reinforcing bar length compensation, improves reinforcing bar concentricity, improve the new reinforcing steel bar branch sleeve of installation effectiveness.
nullFor realizing this utility model purpose，Provide techniques below scheme: a kind of new reinforcing steel bar branch sleeve，Including branch sleeve、It is connected to the connection reinforcing bar I at branch sleeve two ends、Ⅱ，Branch sleeve one end is set to diameter more than the isometrical reducing connecting reinforcing bar I diameter，It is characterized in that in branch sleeve, being provided with the first inner sleeve，Described first inner sleeve external diameter is more than isometrical reentrant diameter but less than branch sleeve internal diameter，Described first inner sleeve one end offers center counter sink，Counter sink processing has female thread，Connect the processing of reinforcing bar I end segments and have external screw thread，The screw-internal thread fit connecting the isometrical reducing of traverse of reinforcing bar I end and the first inner sleeve counter sink spins，The first inner sleeve other end is provided with guide head，Described branch sleeve other end section inwall is provided with female thread，Spin with the external screw thread on one end barrel of the second inner sleeve set up，Second inner sleeve centre bore is through hole，Through-hole wall processing has female thread，Connecting the processing of reinforcing bar II end segments has the screw-internal thread fit of external screw thread and through-hole wall to spin，Described through-hole aperture >=guide head diameter.Female thread in first inner sleeve connects with the external screw thread being connected reinforcing bar one termination, plays interconnection function, and eliminates the gap produced when tension and compression active force between screw thread.
As preferably, connection reinforcing bar II end segments has additional and screws and cap, screws and cap is rotatably connected in the second inner sleeve end.
As preferably, guide head is spherical or taper.
As preferably, connecting reinforcing bar I, II end upset, its external diameter is more than connecting the original diameter of reinforcing bar.
As preferably, described branch sleeve is hexagon or octagonal.
This utility model beneficial effect: this utility model product reaches I grade of jointing requirements in " mechanical connection technique of reinforcement code " JGJ107, can connect in same cross section.It is suitable for the bar connecting of all kinds of occasion different-diameter, expands range of application；Joint is short does not affect stirrup installation；Profile is little does not affect concrete cover；The length of reinforcing bar and bias can be carried out appropriateness adjustment；Fine setting can be carried out by Swiveling Rebar joint during prefabricated post beam installation in position and improve member installation accuracy；Material strain and stress quality of connection will not be produced reliable and stable；The reinforcing bar connected with this joint can make the electric conductor of lightning protection；Reusable edible；Operating personnel is simple to operate, mounting or dismounting are convenient, installation speed is fast；No operatton environmental requirement；Reduce component and support fixation；Coordinate auxiliary connect shaped steel when concrete deficiency can continuously efficiency of construction height；Energy consumption is low, cost is low.
