Abstract
A kind of double-sleeve prestressed reinforcing steel thimble connector and sleeve pipe thereof connect job practices; connector is made up of big sleeve, protective cap and small sleeve; it is than the major diameter connection chamber that big sleeve has sleeve pipe connection chamber and one end; small sleeve one end that the sleeve pipe connection chamber is arranged be can with the described external screw thread link that is connected than the major diameter connection chamber, the protective cap periphery have with described than the combination of major diameter connection chamber external screw thread and this protective cap with big sleeve in conjunction with after be positioned at this plane, big sleeve connectivity port.The present invention can link together minute time successively twice two prestress steel tendon bush in place, and make that prestress steel tendon bush in place no longer passes template earlier and be exposed, thereby simplification construction technology, improve the accuracy and efficiency and the safety of construction, prevent casing damage, can be widely used in prestressed reinforced concrete construction, secondary prestress combining structure of twice connection in place of prestress steel tendon bush needs etc., also can two prestress steel tendon bushes once in place be linked together.
Description
Technical field
The thimble connector and the sleeve pipe thereof that the present invention relates to prestressed reinforcement in the construction of prestressed concrete structure connect job practices, are meant that further double-sleeve prestressed reinforcing steel thimble connector and sleeve pipe thereof connect job practices.
Background technology
In construction of prestressed concrete structure, there is a large amount of prestress steel tendon bushes to need to connect, the connection of prestress steel tendon bush at present mostly is to adopt disposable overstriking sleeve pipe in place to carry out colligation to solve.Existing prestress steel tendon bush link technique can only link together two while prestress steel tendon bushes in place, can't realize for minute time successively connection of twice two prestress steel tendon bush in place; And the development of the segmented job practices of prestressed reinforced concrete construction, and the appearance of some new form of structure in recent years (such as secondary prestress combining structure), connection to the prestress steel tendon bush is had higher requirement, i.e. requirement can realize the connection of twice two prestress steel tendon bush in place successively of branch time easily, so that no longer passing template, elder generation's prestress steel tendon bush in place is exposed, thereby simplify its construction technology, improve efficiency of construction, construction precision and working security, prevent casing damage, existing prestress steel tendon bush link technique all can't realize this requirement.
Summary of the invention
The technical problem to be solved in the present invention is, defective at the prior art existence, propose a kind of double-sleeve prestressed reinforcing steel thimble connector and sleeve pipe thereof and connect job practices, it can link together minute time successively twice two prestress steel tendon bush in place, and make that prestress steel tendon bush in place no longer passes template earlier and be exposed, thereby simplify its construction technology, improve efficiency of construction, construction precision and working security, prevent casing damage, can be widely used in the prestressed reinforced concrete construction of twice connection in place of prestress steel tendon bush needs, in the form of structure such as secondary prestress combining structure.
One of technical scheme of the present invention is; described double-sleeve prestressed reinforcing steel thimble connector is by big sleeve; protective cap and small sleeve are formed; it is female than the major diameter connection chamber that described big sleeve has prestress steel tendon bush connection chamber and one end; the end that the described small sleeve of prestress steel tendon bush connection chamber is arranged be can with described big sleeve than the major diameter connection chamber with the external screw thread link that is threaded, described protective cap periphery has and is positioned at this plane, big sleeve connectivity port after connecting with described big sleeve than the external screw thread of major diameter connection chamber internal thread combination and this protective cap with described big sleeve.
Two of technical scheme of the present invention is to adopt the step of the sleeve pipe connection job practices of described double-sleeve prestressed reinforcing steel thimble connector to be:
A. first prestress steel tendon bush inserted its prestress steel tendon bush connection chamber from an end of described big sleeve, adjust the distance between prestress steel tendon bush and the big larger-diameter end face of sleeve, be the distance between big sleeve and concrete blinding or the concrete end face, and this prestress steel tendon bush is fixedlyed connected with described big sleeve;
What b. described protective cap is placed big sleeve should hold sealing than major diameter connection chamber one end, entered in this big sleeve in order to stop mortar in concreting; Described protective cap is threaded with big preferably adopting than the major diameter connection chamber of sleeve;
When c. after the dismantling concrete template, needing to connect second prestress steel tendon bush; earlier the described protective cap of big sleeve one end is laid down; with same being threaded of sleeve greatly of the external screw thread link of small sleeve, again the prestress steel tendon bush connection chamber of second prestress steel tendon bush insertion small sleeve and fixedly connected than the major diameter connection chamber.
The described fixedly connected heat-shrink tube heated sealant that adopts connects, and also can adopt traditional colligation to connect.
As known from the above, the present invention can link together minute time successively twice two prestress steel tendon bush in place, and make that prestress steel tendon bush in place no longer passes template earlier and be exposed, thereby simplify its construction technology, improve efficiency of construction, construction precision and working security, prevent casing damage, can be widely used in the form of structure such as prestressed reinforced concrete construction, secondary prestress combining structure of twice connection in place of prestress steel tendon bush needs.Obviously, this connector also can connect while two prestress steel tendon bushes in place.The prestress steel tendon bush can be a metal sleeve, also can be the sleeve pipe of other materials.
