Description
Technical field
The present invention relates to a kind of steel bar connecting sleeve of fabricated constructional member of reinforced concrete member.
Background technology
Build in manufacture 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 large new technologies in builing industry.Building is disassembled into component by assembled architecture exactly, and after factory process, transporting to building-site, to carry out lifting assembled.The bar connecting of component and component is exactly main contents of the present invention in the process.The bar connecting of component and component is all in 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, some technical products are also had to improve or Shortcomings and cost high phenomenon from being introduced through abroad.Such as
The deficiency that 1 mechanical connection sleeve exists: reinforcing bar is the technology commonly used the most with mechanical sleeve connection in existing Construction Mode, 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 concreting of cage.Be that component is connected with component in assembling build model, connect under being the immotile prerequisite of reinforcing bar, 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 with various ways (two-sided welding, single-sided welding, docking welding) etc. are unallowed at same cross section bar connecting in existing industry standard.And high temperature can produce the intensity that material change affects reinforcing bar during welding.
3 sleeve slip castings connect the deficiency existed: it is that domestic and international prefabricated units bar connecting popularizes conventional technical products that sleeve slip casting connects, it is middle part bar connecting point being arranged on sleeve that sleeve slip casting connects, first fixed component during construction, after closing gap, pressure fills with high strength slurry, carries out lower road flow chart most when the slurry that pressure is filled with by the time reaches some strength.Be proven and produce following deficiency under these circumstances:
The concrete effective protection aquiclude of the large impact of A sleeve diameter, processing method 1 conventional at present strengthens sectional dimension of members and causes concrete amount to increase and the series of problems of generation.2 reinforcement locations are mobile in component causes behavior of members under loading to weaken.
The long installation affecting stirrup of B slip casting length sleeve, component and component are connected at crux node region usually, and in this region, stirrup needs encryption, and the installation that therefore can affect stirrup causes connected node stress performance to weaken.
C at the construction field (site) Components installation is firm by member supports again after locating, and rear shutoff slip casting region is waited for that plugging material has during intensity and carried out perfusion slurry most, reaches until slurry the construction carrying out lower road flow chart after some strength most.Cause difficulty of construction to increase like this, speed of application such as to slow down at the problem.
D slip casting must have professional's operation, and building-site complexity likely can cause the slip casting of some positions inconvenient and cause slip casting leakiness, and whether slip casting is closely knit does not also have detection means at the scene.Cause like this during slip casting and occur that carelessness just has no idea to make up, have a strong impact on bar connecting quality.
The deficiency that 4 Bar Anchorage overlap joints exist: reserving hole in prefabricated units, connecting reinforcement stretches out outside component, shutoff slip casting region after lifting contraposition at the scene, waits for that plugging material has during intensity and carries out perfusion slurry most, reach until slurry the construction carrying out lower road flow chart after some strength most.Cause difficulty of construction to increase like this, speed of application such as to slow down at the problem.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide one and effectively prevent axial compression, improve bonding strength, and the new reinforcing steel bar branch sleeve that can realize reinforcing bar length compensation, improve reinforcing bar concentricity, improve installation effectiveness.
For realizing the object of the invention, provide following technical scheme: a kind of new reinforcing steel bar branch sleeve, comprise branch sleeve, be connected to the connecting reinforcement I at branch sleeve two ends, II, branch sleeve one end is set to the isometrical reducing that diameter is greater than connecting reinforcement I diameter, it is characterized in that in branch sleeve, being provided with the first inner sleeve, described first inner sleeve external diameter is greater than isometrical reentrant diameter but is less than branch sleeve internal diameter, described first inner sleeve one end offers center counter sink, counter sink is processed with internal thread, connecting reinforcement I end segments is processed with external screw thread, connecting reinforcement I end spins through the screw-internal thread fit of isometrical reducing and the first inner sleeve counter sink, the first inner sleeve other end is provided with guide head, described branch sleeve other end section inwall is provided with internal 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 is processed with internal thread, the screw-internal thread fit that connecting reinforcement II end segments is processed with external screw thread and through-hole wall spins, described through-hole aperture >=guide head diameter.Internal thread in first inner sleeve is connected with the external screw thread of connecting reinforcement one termination, plays connection function, and eliminates the gap produced when tension and compression active force between screw thread.
As preferably, connecting reinforcement 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 reinforcement I, II end pier are thick, and its external diameter is greater than the original diameter of connecting reinforcement.
As preferably, described branch sleeve is hexagon or octagon.
Beneficial effect of the present invention: product of the present invention reaches I grade of jointing requirements in " mechanical connection technique of reinforcement code " JGJ107, can connect in same cross section.Be suitable for the bar connecting of all kinds of occasion different-diameter, expand range of application; Joint is short does not affect stirrup installation; Profile is little does not affect concrete cover; Appropriateness adjustment can be carried out to the length of reinforcing bar and bias; Carry out fine setting by Swiveling Rebar joint during prefabricated post beam installation in position and improve member installation accuracy; Material strain and stress quality of connection can 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 member supports fixation; Coordinate auxiliary connect shaped steel when concrete is not enough can sequential production efficiency high; Energy consumption is low, cost is low.
