Description

A kind of precast concrete vertical member grouting channel design method
Technical field
The present invention relates to the grouting techniques used when a kind of prefabrication and assembly construction building vertical member is vertically connected with, and in particular to one Kind precast concrete vertical member grouting channel design method, belongs to construction engineering technical field.
Background technology
Precast concrete vertical member is widely suitable in the buildings such as all types of Gongjian, China Democratic National Construction Association at present, different interlayers Precast concrete vertical member mostly uses reinforced bar sleeve grouting connection.Reinforcing bar grout sleeve catenation principle mainly passes through high-strength filling Filled therewith hypomere prefabricated components reserved steel bar and epimere prefabricated components reserve the gap between barrel bore, make reinforcing bar and sleeve Between form bonding strength and meet the jointing of design requirement.Grouting material compaction rate decides grout sleeve in grout sleeve Whether the bonding strength of connector connector meets design requirement.
Traditional precast concrete vertical member grouting mostly uses pressure grouting, and grouting mouth is arranged in the lower part of grout sleeve Grouting mouth is arranged at upper and lower prefabricated components horizontal joint, and being sequentially filled prefabricated components from bottom to up by the method for pressure fills Starch the gap of sleeve inner.But such pressure grouting method is in the milk due to the influence of gravity and is covered when lower part grouting mouth is blocked Grouting material is not solidified in cylinder and will produce leakage, leads to the grouting material leakiness in grout sleeve, fill, and then influences grouting set The intensity of cylinder connector jointing.
Invention content
Goal of the invention:Present invention aims in view of the deficiencies of the prior art, provide a kind of precast concrete vertical member Grouting channel design method, this method can make that precast concrete vertical member grouting quality is qualified, stablizes, grouting material without leaking, Constructing operation is easy, disclosure satisfy that the quality requirement of precast concrete vertical member Grouted density.
Technical solution:A kind of precast concrete vertical member grouting channel design method of the present invention, including following step Suddenly:
The first step, prefabricated epimere precast concrete vertical member and hypomere precast concrete vertical member, and the epimere is pre- Concrete vertical member processed is connected with hypomere precast concrete vertical member by prefabricated components vertical reinforcement, epimere concrete The junction of native vertical member and hypomere precast concrete vertical member has upper and lower prefabricated components horizontal joint;Go to second Step;
Second step, prefabricated first bottom keyway, the second bottom keyway, L-type grout pipe in epimere precast concrete vertical member Road and L-type observe pipeline, and first bottom keyway is connected with the second bottom keyway, and first bottom keyway and the Two bottom keyways are connected to upper and lower prefabricated components horizontal joint;Go to third step;
First bottom keyway is connected by third step with the L-type grout lines being arranged at the top of it, second bottom keyway It is connected with the L-type observation pipeline being arranged at the top of it;Go to the 4th step;
4th step is located at setting reinforcing bar grouting set at prefabricated components vertical reinforcement in the lower part of epimere precast concrete vertical member Cylinder, the reinforcing bar grout sleeve are connected to upper and lower prefabricated components horizontal joint, then prefabricated components horizontal joint above and below closure Side seam;Go to the 5th step;
5th step, grouting material sequentially enter the second bottom keyway, upper and lower prefabricated components horizontal joint and first by L-type grout lines It in the keyway of bottom, is then discharged under pressure by the grout outlet of reinforcing bar grout sleeve, grouting material is from reinforcing bar grout sleeve The grout outlet of reinforcing bar grout sleeve is blocked after grout outlet discharge;Go to the 6th step;
6th step, grouting material continuation are entered by L-type grout lines, until the grout outlet of L-type observation pipeline has grouting material discharge, are sealed The grout outlet of stifled L-type observation pipeline, finally blocks the grouting mouth of L-type grout lines.
Further, first bottom keyway, the second bottom keyway are arranged in epimere precast concrete vertical member Bottom end, and first bottom keyway, the second bottom keyway are in inner concave shape.
Further, the L-type grout lines include vertical section and horizontal segment, the vertical section and the second bottom keyway phase Even, the horizontal segment extends to column side, and the horizontal segment is higher than the upper end grout outlet 200mm of reinforcing bar grout sleeve.
Further, L-type observation pipeline includes vertical section and horizontal segment, the vertical section and the first bottom keyway phase Even, the horizontal segment extends to column side, and the horizontal segment is higher than the upper end grout outlet 100mm of reinforcing bar grout sleeve.
Further, the reinforcing bar grout sleeve includes vertical sleeve, on the vertical sleeve have upper end grout outlet and Lower end grout outlet, the upper end grout outlet, lower end grout outlet extend horizontally to column side.
The horizontal segment of L-type observation pipeline is higher than reinforcing bar grout sleeve in the present invention, and L-type observes the grout outlet of pipeline in pulp When can determine that grouting material is full, full inside reinforcing bar grout sleeve;The horizontal segment of L-type grout lines is higher than reinforcing bar grouting set Cylinder when the grouting mouth of L-type grout lines blocks, will not lead to steel because grouting material in the horizontal segment of L-type grout lines leaks outside Grouting material leakage in muscle grout sleeve;When the grouting material in reinforcing bar grout sleeve causes thanks to square because of contraction, L-type grout pipe Road and L-type are observed grouting material in the horizontal segment of pipeline and are further ensured that in reinforcing bar grout sleeve because gravity can be compensated by time Grouting material it is closely knit.
The beneficial effects of the invention are as follows grouting material when grouting without leak, constructing operation it is easy, it is vertical to meet precast concrete The quality requirement of component Grouted density.
