Abstract
The utility model discloses the roll forming bar connecting grout sleeve jointing for the connection of reinforcing bar assembling in a kind of building operations.The making of roll forming bar connecting grout sleeve is that its external diameter local distortion is reduced, internal diameter local distortion protruding by making by the mechanical rolling of design position and projected depth outer diameter of steel pipes, be formed with convex, recessed shearing groove, this method is formed with convex, recessed shearing groove convenience than machining endoporus by removing part endoporus material, efficiency is high, material is fully used, cost reduces, and is the novel grout sleeve for the connection of reinforcing bar assembling in a kind of building operations.The purpose of this utility model be to provide a kind of simple to operate, efficiency is high, consumptive material is few, dependable performance for reinforcing bar assembling connect roll forming bar connecting grout sleeve joint.
Description
Technical field:
The utility model relates to the roll forming grout sleeve jointing for the connection of reinforcing bar assembling in a kind of building operations
Background technology:
In traditional cast-in-place concrete structure, the modes the such as more connection of reinforcing bar adopts overlap joint to connect, is welded to connect, compression sleeve connection or screw shell mechanical connection, the construction of this several connected mode is comparatively complicated, and bar connecting must be completed before fluid concrete, be not suitable for the fabricated construction of precast concrete.The grout sleeve for precast concrete fabricated construction grown up for nearly 2 years mainly contains machining grout sleeve and the grout sleeve of casting.Because grout sleeve entire length size is large, (full grout sleeve is greater than 16 times of bar diameters, half grout sleeve 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, high material consumption, inefficiency.
Utility model content:
The purpose of this utility model be to provide a kind of simple to operate, efficiency is high, consumptive material is few, cost is low, the roll forming bar connecting grout sleeve of dependable performance.Feature of the present invention is, the making of roll forming bar connecting grout sleeve is by the rolling of outer diameter of steel pipes by design position and projected depth, its internal diameter local distortion is reduced, internal diameter local distortion projection 1.5 ~ 3mm, be formed with convex, recessed shearing groove, add reinforcing bar, anchored force between grout material and grout sleeve, improve anti-seismic performance.By removing part endoporus material, this method is formed with that convex, recessed shearing groove is convenient, efficiency is high, consumptive material greatly reduces than machining endoporus, material is fully used, and cost reduces.
Accompanying drawing illustrates:
Accompanying drawing is roll forming bar connecting grout sleeve sectional drawing, and Fig. 1 is full grout sleeve sectional drawing, and Fig. 2 is half grout sleeve sectional drawing.
Roll forming bar connecting grout sleeve, is divided into full grouting branch sleeve and half grouting branch sleeve two kinds.Full grouting branch sleeve composition comprises: joint (4), sealing ring (5) are starched in full grout sleeve (1), spacing backing pin (2), two grouting end bar (3), filling (row), and half grouting branch sleeve composition comprises: the end bar (3) that is in the milk, filling (row) slurry joint (4), sealing ring (5), half grout sleeve (6), straight screw connection end sleeve end cap (7), reinforced bar straight thread termination (8).
Detailed description of the invention:
Roll forming bar connecting grout sleeve is divided into full grout sleeve and half grout sleeve two kinds.
1, the complete full site assembly of grout sleeve: first two sealing rings (5) are inserted in two grouting end bars (3) by specific length (8 times of bar diameters) respectively, again full grout sleeve (1) is inserted in two grouting end bar (3) respectively, and two sealing rings (5) are enclosed within full grout sleeve (1), namely by filling (row) slurry joint (4) grouting, the connection of two grouting end bars (3) is completed.
2, complete prefabricated half site assembly of grout sleeve half:
1/ prefabricated end: first sealing ring (5) is inserted in prefabricated grouting end bar (3) by specific length (8 times of bar diameters), again prefabricated grouting end bar (3) is inserted full grout sleeve (1), and sealing ring (5) is enclosed within full grout sleeve (1), namely by filling (row) slurry joint (4) grouting, the connection of prefabricated grouting end bar (3) is completed.
2/ site assembly end: first sealing ring (5) is inserted in site assembly grouting end bar (3) by specific length (8 times of bar diameters), the end bar (3) that site assembly is in the milk again inserts full grout sleeve (1), and sealing ring (5) is enclosed within full grout sleeve (1), namely by filling (row) slurry joint (4) grouting, the connection of site assembly grouting end bar (3) is completed.
3, be partly in the milk branch sleeve: half grout sleeve is Split assembled structure, and a part is roll forming bar connecting half grout sleeve, and another part is the sleeve end cap having interior straight screw connection end, both being threaded togather with its correspondence.This half grouting branch sleeve is comparatively applicable to the pre-buried of building structural member, can save portion of material than full grout sleeve.Its connection realizes in the following manner, first the pre-buried reinfored bar rolling of palpus or turning are gone out screw thread silk capitiform and become reinforced bar straight thread termination (8), be threaded connection integral with the assembly of half grout sleeve (6) connected and straight screw connection end sleeve end cap (7) again, both can cast reinforcing bar and half grout sleeve pre-buried.Other end site assembly end is constructed, first sealing ring (5) is inserted in site assembly grouting end bar (3) by specific length (8 times of bar diameters), the end bar (3) that site assembly is in the milk again inserts half grout sleeve (6), and sealing ring (5) is enclosed within full grout sleeve (6), namely by filling (row) slurry joint (4) grouting, the connection of site assembly grouting end bar (3) is completed.
Shaping being through of the internal diameter of the utility model roll forming bar connecting grout sleeve makes its internal diameter local distortion reduce by design position and projected depth by rolling to outer diameter of steel pipes, be formed with convex, recessed shearing groove, by removing part endoporus material, this method is formed with that convex, recessed shearing groove is convenient, efficiency is high, consumptive material greatly reduces than machining endoporus, material is fully used, and cost reduces.
The utility model is compared with existing product, and tube-in-tube structure is reasonable in design, and material is fully used, and the unnecessary consumption of material greatly reduces, and cost reduces, and be widely used, construction technology is easy, dependable performance, is applicable to the fabricated construction of precast concrete.
Claims (3)
1. roll forming bar connecting grout sleeve is divided into full grouting branch sleeve and half grouting branch sleeve two kinds, its common trait is: grout sleeve inner radius has convex, recessed shearing groove is by being formed the mechanical rolling of outer diameter of steel pipes, full grouting branch sleeve composition comprises: full grout sleeve (1), spacing backing pin (2), two grouting end bar (3), fill with (row) slurry joint (4), sealing ring (5), half grouting branch sleeve composition comprises: grouting end bar (3), fill with (row) slurry joint (4), sealing ring (5), half grout sleeve (6), straight screw connection end sleeve end cap (7), reinforced bar straight thread termination (8).
