Description
Technical field:
The invention discloses the Split type steel bar sleeve connected for concrete prefabricated element assembling in a kind of building operations to be partly in the milk joint.
Background technology:
Precast concrete be equipped with various ways, but mainly to prepare the connection of steel bar stress in prefabricated units, complete the assembling of prefabricated units.Bar splicing obviously can not meet the needs of prefabricated units assembling, and the usual lap length of reinforcing bar is 35d, and the preset clearance at this moment between component is excessive, and cast-in-place part increases greatly.Precast unit factorial praluction loses meaning.And welding procedure also requires to leave between component comparatively large artificial operating clearance, and weld interval is long, and the supporting of component is very difficult.Thus mechanical splice bar connecting becomes unique solution, current mechanical splice is main based on straight thread connector, cold extruded joint, taper thread joint in cast-in-situ concrete, the feature that the connection speed that is wherein threaded is fast and intensity is high, but they generally need certain operating space and are required high to connecting the relative position of reinforcing bar, operability is declined greatly, the construction of this several connected mode is also comparatively complicated, and bar connecting must be completed before fluid concrete, be not suitable for the fabricated construction of precast concrete.For these special circumstances, create new bar connecting system---reinforced bar sleeve grouting joint, its anti-seismic performance is reliable, easy construction, can the reduction of erection time, be applicable to vary in size the connection of Ribbed Bar of diameter, more important point is the slitless connection that it has really accomplished between component, solves the difficult problem that precast concrete prefabricated member connects.
Reinforced bar sleeve grouting joint is divided into again entirely be in the milk joint and reinforced bar sleeve of reinforced bar sleeve to be partly in the milk joint.Within nearly 2 years, save material, easy to operate and be widely used due to reinforced bar sleeve half grouting joint.Reinforced bar sleeve half grouting joint adopts half grout sleeve connecting reinforcement.Half grout sleeve for precast concrete fabricated construction grown up mainly contains machining with half grout sleeve that is casting.Because grout sleeve entire length size is large, (full grout sleeve length is greater than 16 times of bar diameters usually, half grout sleeve length is greater than 8 times of bar diameters) and grout sleeve inner hole wall is provided with convex, recessed shearing groove, machining or casting difficulty are increased, especially half grout sleeve requires that one end and screw thread steel are mechanically connected, the other end is in the milk with reinforcing bar and is connected, the different connected mode in half grout sleeve two ends makes integral type half grout sleeve two stomidium difference in internal diameters larger, must process with bar, processing inconvenience, and must lot of materials be removed, process length consuming time, high material consumption, inefficiency.Machining accuracy cannot ensure, causes sleeve wall thickness to increase, have lost the thickness of concrete cover.Run into the connection of Large-size rebar, grout sleeve endoporus slenderness ratio is excessive, and difficulty of processing strengthens, and processing cost increases greatly, almost cannot realize with machine-tooled method.And castability not easily ensures, the high application that also counteracts that half grout sleeve of cost.For this difficult problem, Split type steel bar sleeve half grouting joint can be processed from materials in the tube two ends, makes endoporus processing length reduce by 1/2, solves a production difficult problem.
Summary of the invention:
The object of this invention is to provide a kind of simple to operate, efficiency is high, consumptive material is few, precision is high, the Split type steel bar sleeve of dependable performance is partly in the milk joint.Feature of the present invention is: Split type steel bar sleeve half grouting joint is two body combining structures, a part is grouting end sleeve, another part is the sleeve end cap having interior straight screw connection end, and grouting end sleeve links together with corresponding internal and external screw thread with the sleeve end cap of straight screw connection end.Diameter of thread on grouting end sleeve is less than or equal to trapezoidal groove internal diameter, and be provided with 3-5 trapezoidal groove in grouting end sleeve, the degree of depth of trapezoidal groove is 1.5-3mm.Tubular object extruding is higher than employing round steel bar overall processing shaping efficiency, consumptive material is few, cost is low because grouting end sleeve can adopt for this Split type structure.And endoporus can be processed from two ends, make difficulty of processing reduce half, machining accuracy is greatly enhanced, and wall thickness can be made to accomplish when guaranteed strength requires the thinnest, adds the thickness of concrete cover.
