Abstract
The utility model discloses a kind of connection grout sleeve of prefabricated member reinforcing steel bar, it has solved the connectivity problem of prefabricated member reinforcing steel bar, construct simple, with low cost, intensity is high, connection is reliable.It comprises: sleeve body, sealing ring and caging bolt, and sleeve body is provided with grout hole, steam vent caging bolt, and inwall is provided with block-shaped protrusion, and in sleeve body, sealing ring is equipped with at two ends.When prefabricated units assembling construction, be screwed into caging bolt, the reserved steel bar of two prefabricated members be inserted to from the two ends of sleeve body and limit position, clamp-on elastic packing rubber ring, pour into strength cement-based grouting material from grout hole, two reserved steel bars are connected in one by sleeve.The utility model can be for the connection of various prefabricated member reinforcing steel bars.
Description
Technical field
The utility model relates to concrete prefabricated element technical field, and exactly it is a kind of connection grout sleeve of prefabricated member reinforcing steel bar.
Background technology
In traditional cast-in-place concrete structure, the connection of reinforcing bar adopts overlap joint to connect, be welded to connect or the method such as compression sleeve mechanical connection more, its work progress is comparatively complicated, and the quality of connection of reinforcing bar is also difficult to ensure, and must before concreting, completes the connection of reinforcing bar.Key issue is: the reinforcing bar that the connected mode of this reinforcing bar can not be applicable to prefabricated member connects.
summary of the invention
The utility model object is exactly the connection grout sleeve that a kind of prefabricated member reinforcing steel bar is provided for the connection of prefabricated member reinforcing steel bar, and it has, and construction is simple, the feature of dependable performance.
The purpose of this utility model is to realize like this.Prefabricated member reinforcing steel bar connects grout sleeve and comprises: sleeve body, elastic packing rubber ring and caging bolt.It is characterized in that: the two ends of sleeve body are provided with grout hole and steam vent, grout hole and steam vent inwall are provided with screw thread, and in sleeve body, elastic packing rubber ring is equipped with at two ends, and sleeve body is provided with caging bolt 3, and sleeve body inwall is provided with block-shaped protrusion.
The construction method that prefabricated member reinforcing steel bar grout sleeve connects, it is characterized in that: prefabricated member is after produce in factory moulding, its reserved steel bar can insert in sleeve body temporarily completely, and temporary fixed with caging bolt, when assembling construction, unclamp caging bolt, take off sleeve body, first two elastic packing rubber rings are enclosed within respectively to reserved steel bar and upper, be screwed into caging bolt, in order to limit reinforcing bar and the reinforcing bar position in sleeve, be inserted to by the reserved steel bar of two prefabricated members with from the two ends of sleeve body and limit position, clamp-on elastic packing rubber ring, grouting lance is connected with grout hole by screw thread, pour into strength cement-based grouting material, after grouting material setting and harden, reserved steel bar and reserved steel bar are connected in one by sleeve.According to Specific construction environment, the function of grout hole and steam vent can be exchanged, and steam vent is as grout hole, and grout hole is as steam vent.
The utility model has the advantages that: thoroughly solved the connectivity problem of prefabricated member reinforcing steel bar, construction is simple, work progress does not need complicated plant equipment and facility, with low cost, intensity is high, connection is reliable.The grout hole arranging on sleeve body and steam vent, can be in the time pouring into strength cement-based grouting material, and the air in sleeve body is from the smooth and easy eliminating of steam vent.The block-like protrusions of sleeve body inwall, can make strength cement-based grouting material and reinforcing bar, union body firmly combine, the elastic packing rubber ring at sleeve body two ends has avoided grouting material to flow out from sleeve body two ends before setting and harden completely, caging bolt can ensure the correct design attitude of both sides reinforcing bar, can obtain again reliable connection effect.
Brief description of the drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is that A-A of the present utility model is to sectional drawing.
Detailed description of the invention
Embodiment 1:
Sleeve body 1 of the present utility model can be cast and make, and is the smooth demoulding, and the middle part wall thickness of sleeve body 1 can be greater than two ends, so also more meets the regularity of distribution that sleeve body middle part internal force is large, two ends internal force is little.The independent cube of block-shaped protrusion 6 that sleeve lining arranges, ensures the bond effect between reinforcing bar 7 and 8, grouting material and sleeve body 1, after grouting material setting and harden, two reserved steel bars is connected in one by sleeve.The external diameter of the elastic rubber sealing ring 2 at sleeve body 1 two ends is greater than the internal diameter of sleeve body 1, and it is smaller that the internal diameter of elastic rubber sealing ring 2 is less than the external diameter of reinforcing bar 7 and 8, to ensure sealing effectiveness.Caging bolt 3 is arranged on sleeve body 1.The grout hole 4 at sleeve body 1 two ends and the function of steam vent 5 can be exchanged, that is: 5 as grout hole, and 4 as steam vent, thus inwall all should be threaded, for being connected with grouting lance.
Embodiment 2:
Construction method of the present utility model is as follows.Prefabricated member is after produce in factory moulding, reserved steel bar 7 can insert in sleeve body 1 temporarily completely, and temporary fixed with caging bolt 3, lose to avoid sleeve, when assembling construction, unclamp caging bolt 3, take off sleeve body 1, first two elastic packing rubber rings 2 are enclosed within respectively on reserved steel bar 7 and 8, be screwed into caging bolt 3, in order to limit reinforcing bar 7 and the position of reinforcing bar 8 in sleeve, the reserved steel bar of two prefabricated members 7 and 8 is inserted to from the two ends of sleeve body 1 and limits position, clamp-on elastic packing rubber ring 2, grouting lance is connected with grout hole 4 by screw thread, pour into strength cement-based grouting material, when grouting, steam vent 5 is unimpeded, discharge smoothly to ensure the air in sleeve body 1 chamber, strength cement-based grouting material is closely knit.After grouting material setting and harden, reserved steel bar 7 and reserved steel bar 8 can be connected in one by sleeve.According to Specific construction environment, the function of grout hole 4 and steam vent 5 can be exchanged, that is: 5 as grout hole, and 4 as steam vent.
