Abstract
The utility model relates to a quake-proof steel tie bar embedded part, which comprises a sleeve fixing support connected with a concrete embedded steel bar. The sleeve fixing support comprises a sleeve and an extensible elastic cap cover. Inner threads or reverse tooth structures are arranged in the sleeve. The sleeve is fixed on the sleeve fixing support, and the extensible elastic cap cover is butted against a casting concrete formwork in compression mode. By means of the technical scheme, the quake-proof steel tie bar embedded part is embedded inside the concrete without influencing erection of the concrete formwork, particularly not penetrating out of the formwork, thereby facilitating the erection and dismount of the formwork. The formwork does not require hole drilling, thereby avoiding damage to the formwork in constructions. As a customized product which is produced according to a design size in advance, the size accuracy of the quake-proof steel tie bar embedded part is higher than that of methods of hole drilling on the formwork or later rib embedding and the like. As a concealed construction, the quake-proof steel tie bar embedded part can be inspected together with steel bar constructions, and construction quality can be effectively ensured.
Description
Technical field
The utility model relates to a kind of concrete structure tension rib built-in fitting, particularly relates to a kind of reinforced concrete structure antidetonation tension rib built-in fitting.
Background technology
In the anti-seismic construction technical measures of current architecture configuration engineering; Adopt tension rib to realize between the isostructural body of wall of concrete structure and masonry mostly; These technical measures require antidetonation tension rib one end to be embedded in the concrete structure, and the other end is embedded in the masonry structure.For the building of construction masonry structure behind the concrete structure of constructing earlier, template will be cut off tension rib during owing to concrete structure construction, and the punching realization penetrates the tension rib way of concreting again on the employing template; Can destroy template, cause template discarded, do not adopted basically by construction party; And at present more be to adopt the way of planting behind the tension rib, after to plant construction method be main with chemical anchoring agent bar planting, there is following problem in the way of this back bar planting: 1, the back bar planting need punching can destroy structure to a certain extent on concrete structure; 2, the back bar planting is run into reinforcing bar easily and is caused hole to scrap when drilling operation, and makes the bar planting position occur changing, and 3, because tension rib is horizontal positioned basically; The bar planting hole is to be the level of state; Liquid chemical anchoring agent is not easy to fill with, and can influence anchoring effect, and 4, the constructing operation more complicated; Of poor quality, performance guarantees relatively low.
The utility model content
In view of this; The technical problem that the utility model will solve is; A kind of antidetonation tension rib built-in fitting is provided; Through the present technique scheme, with tension rib be designed to built-in fitting install before the concrete construction in construction pre-buried, then when concrete construction is accomplished the back masonry and is constructed with built-in fitting and the latter linked form of tension rib.The tension rib built-in fitting is with the supplied construction of finished product accessory.
The present technique utility model solves the technical scheme that its technical problem adopted: a kind of antidetonation tension rib built-in fitting; Comprise the sleeve fixed support; Said sleeve fixed support is connected with concrete embedded reinforcing bar, comprises sleeve and telescopic elastic cap, is provided with internal thread or pawl structure in the said sleeve; Said sleeve is fixed on the sleeve fixed support, and the cap on the said telescopic elastic cap is pressed on the concreting template.
Said telescopic elastic cap is a column or horn-like; Constitute by adapter sleeve, shell covering, spring and cap; Said adapter sleeve is connected with the shell covering that flexible material is processed, and said spring is arranged in the shell covering, and an end of said spring is pressed on the cap; The adapter sleeve of said telescopic elastic cap is fixed on the sleeve.
As the technical scheme of optimizing, when said telescopic elastic cap was horn-like, said compression spring was a tower compression spring.
Said telescopic elastic cap is processed for the telescopic elastic pipe, and an end of said telescopic elastic pipe is sleeved on the sleeve, and the other end of telescopic elastic pipe is bonded with cap, and said cap is pressed on the concreting template.
Said sleeve one end is set to cecum, in sleeve cecum arranged outside anchor slab or dowel is arranged.Comprise the sleeve fixed support, said sleeve fixed support is concrete embedded, comprises sleeve and telescopic elastic cap; Said sleeve is a cylindrical tube shape, in sleeve, is provided with internal thread or pawl structure, and said telescopic elastic cap is a column or horn-like; Constitute by adapter sleeve, shell covering, spring and cap; Said adapter sleeve is connected with the shell covering that flexible material is processed, and said spring is arranged in the shell covering, and an end of said spring is pressed on the cap; The adapter sleeve of said telescopic elastic cap is fixed on the sleeve, and said sleeve is fixed on the sleeve fixed support, and the cap on the said telescopic elastic cap is pressed on the concrete blinding.
Said sleeve one end is set to cecum, in sleeve cecum arranged outside anchor slab or dowel is arranged.
In practical application, said sleeve is fixed on the sleeve fixed support with certain fixed form, and scalable sleeve cap is fixed on the sleeve; The other end of scalable sleeve cap is pressed on concrete blinding, makes the outer end of cap be adjacent to template, makes cap after form removable, be directly exposed to concrete surface; Thereby can effectively avoid for seeking built-in fitting concrete being picked cutter, process screw thread in the sleeve, the tension rib end is connected through screw thread; When processing the pawl structure in the sleeve or during sleeve lining roughening deformation process; Be full of bar planting glue class anchoring agent in the sleeve, tension rib is through pawl structure and inner wall coarse deformation process, to strengthen the connection effect of using the anchoring agent; Sleeve fixed support and sleeve link together, and are used for fixing the position and the spacing of sleeve.
The technique effect that the utility model reaches is following: a kind of antidetonation tension rib built-in fitting, be embedded in inside concrete, and do not influence installing of concrete blinding; Particularly need not pass template, thereby make things convenient for installing and removing of template, template need not be punched; Thereby avoided in the construction destruction to template; Through the present technique scheme, on concrete component, punch without the later stage, thereby avoided destruction concrete component; Antidetonation tension rib built-in fitting is as the approved product of making by design size in advance, and its size accuracy is superior to the accuracy of way such as punching or back bar planting on template.When antidetonation tension rib built-in fitting when the substructure face is counted size between first sleeve and the structural plane and is not met the masonry modulus because of reasons such as installation cause; On this place's structural level, can increase cement mortar or concrete way and adjust size to satisfy the modulus requirement.Antidetonation tension rib built-in fitting can be used as a concealed work and carries out an acceptance inspection with reinforced bar engineering, can effectively guarantee construction quality.
