Description
[technical field]
The present invention relates to prefabricated concrete structure field, be specially a kind of there is interior welds fin bar connecting grout sleeve and manufacture method and using method, be mainly used in the bar connecting between assembly concrete building prefabricated components.
[background technology]
In traditional cast-in-place concrete structure, the connection of reinforcing bar adopts overlap joint to connect more, be welded to connect or the mechanical joining methods such as compression sleeve, the construction of bar connecting is comparatively complicated, and the connection of reinforcing bar must be completed before fluid concrete, the connection of reinforcing bar between prefabricated units cannot be realized, thus cannot carry out prefabricated construction.
Bar connecting between assembly concrete building prefabricated components needs to use sleeve grouting to connect, and to be inserted by two velamen connecting reinforcements in metal sleeves and pour into high-performance water cement mortar in the space between sleeve and reinforcing bar.Because reinforcing bar external surface and sleeve interior surface have the horizontal fin of distribution separately, after cement mortar sclerosis, between three, mutual build-in occlusion makes reinforcing bar be difficult to be pulled out, thus realizes the connection of reinforcing bar.This connection does not need welding, does not need wet construction, and the reinforcing bar be connected in two components such as can to reach at the strong ties.
The principal character of bar connecting grout sleeve is the processing method of the fin of sleeve lining.At present, bar connecting grout sleeve mainly contains two kinds, and one is casting, and another kind is the core bore cutting working method of thick walled steel tube or rod iron.The former has high requirement to the cast metal material such as cast iron or cast steel, and need again artificial founding shaping, production efficiency is low, difficult quality guarantee.Although the latter belongs to machining, cut difficulty greatly, waste of material is many, and processing cost is high.
[summary of the invention]
The object of the present invention is to provide a kind of there is interior welds fin bar connecting grout sleeve and manufacture method and using method, solve that the casting production efficiency existed in prior art is low, mechanical processing difficulty large and high in cost of production problem.
Technical scheme of the present invention is:
Have a bar connecting grout sleeve for interior welding fin, this grout sleeve, using universal seamless steel pipe as sleeve base material, is formed with welding manner and is consolidated in sleeve lining and higher than the welding fin of sleeve lining, uses sleeve grouting connecting reinforcement.
