Abstract
The utility model provides an end part thickened grouting connector of a steel bar, comprising two connecting steel bars, a metal tubular connecting sleeve, and non-shrinkage cement mortar filled between the steel bar and the sleeve, wherein an anchoring head with the diameter which is 1-10mm greater than the original outer diameter of the connecting steel bar is arranged at the end part of at least one connecting steel bar; and the connecting steel bar and the anchoring head stretch into a grouting part of the connecting sleeve and are combined with the connecting sleeve through the cement mortar hardened in the grouting part to form a connecting body. In a grouting cavity in a cement grouting connector of the steel bar, the anchoring head is arranged at the end of the connecting steel bar and the diameter of the anchoring head is 1-10 mm greater than the original outer diameter of the connecting steel bar to effectively increase a bearing area of the cement mortar in the connector grouting cavity and the connecting steel bar, so that a limit value of a pull force load of the grouting connector is improved.
Description
Technical field
The utility model relates to a kind of structure that prefabricated concrete structure prefabricated units Ribbed Bar connects that is applied to.This structure is superior to existing cementation rebar connecting technology at aspects such as material consumption and manufacturing costs, can connect the reinforcing bar of vertical, horizontal or oblique layout, therefore can be widely used in the fabricated construction system.
Background technology
In the modern prefabricated concrete structure building operations, the steel bar stress of prefabricated units mainly adopts the cementation method of attachment to connect.The cementation bar splice shrinks high-strength cement mortar (or claiming cementation material) by branch sleeve, nothing and the Ribbed Bar of sleeve two ends connection is formed; Its principle is: will not have the high-strength cement mortar of contraction and pour into branch sleeve; Fill the gap between full sleeve and the reinforcing bar; Cement mortar sclerosis back high-strength concrete that forms and the reinforcing bar that has cross rib are combined closely with the sleeve lining that has internal thread, and two reinforcing bars are linked together.
Traditional cement grouting joint all adopts the cast metal branch sleeve, and state-of-the art cementation joint is the joint of compound type of attachment, and branch sleeve is made with round steel or seamless steel pipe; One end of sleeve is connected with cementation with reinforcing bar, and the other end of sleeve adopts with reinforcing bar and is threaded, and is compared to traditional grouting joint; This joint appearance and size is obviously dwindled; Especially length dimension obviously reduces, and the globality of concrete component makes moderate progress, and the length (also claiming anchorage length) of part is still at least at more than 5 times of bar diameter but this joint grouting link reinforcing bar combines with cement mortar; Therefore the length dimension of sleeve is still bigger; High material consumption, the problem that cost is high are solved at all, and for the branch sleeve of the bigger joint of bar diameter, it is outstanding that this problem shows especially.
Industrialized building is the main developing direction of Future in China builing industry; High-rise prefabricated concrete structure building is to having very wide development space in the Urban House field; Key technology-reinforcing bar of resolving the fabricated construction globality connects; Guaranteeing to have on the excellent switching performance basis, research is joint and tube-in-tube structure more reasonably, and the popularization in the industrialized building is had great importance.
In the existing cementation connecting method for reinforcing bars, any bulk processing that adds is not carried out in the termination of connecting reinforcement, and after the cement mortar of treating joint perfusion was solidified, the cross rib of reinforcing bar was embedded in the cement mortar, forms anchor connection.When member is stressed, mainly bear pressure by the concrete of member; When member receives pulling force, then bear pulling force by reinforcing bar in the member and bar splice.The cement mortar of anchor bar is stressed in the joint when reaching its utmost carrying ability, promptly destroys prior to reinforcing bar, between reinforcing bar and the cement mortar relative displacement takes place, and the cement mortar between the reinforcing bar cross rib is sheared and comes off.Because cement mortar depends primarily on the profile of reinforcing bar and the intensity of cement mortar to the anchored force of reinforcing bar; After the intensity of reinforcing bar profile, size and cement mortar was confirmed, the anchorage length of steel bar of cementation reinforcing bar jointing grouting linkage section is just basic to have been confirmed.The profile of reinforcing bar, size are stipulated by its product standard, can not change because of grouting connects; Cement mortar is to be processed by non-shrinkage cement base grouting material and the even mix of water; Certain operable time, multiple performance requirement such as strong, high fluidity and microdilatancy are early arranged; 28 days compressive strength of cement mortar that present reinforcing bar jointing is processed with the cementation material has reached more than the 85MPa; The space of on the basis that guarantees correlated performance, further improving the strength of materials is limited; Therefore, the technology path that shortens anchorage length of steel bar through the intensity that improves the cementation material is difficult to obtain fairly obvious effect.
Summary of the invention
To the deficiency of said cementation method of attachment, the purpose of the utility model is: a kind of end reinforced overstriking grouting joint is provided, through jumping-up, be threaded or mode such as welding, steel bar end is carried out overstriking.This method is through the anchorage head of end reinforced overstriking; The loaded area of the cement mortar in the joint grouting chamber is increased; And it is stressed more reasonable; When reinforced concrete grouting joint bears tensile load, can improve the supporting capacity area of cement mortar effectively, thereby improve the limiting value that joint can bear load.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
