Abstract
The invention relates to an anti-seismic lacing bar embedded part which comprises a sleeve fixing support, wherein the sleeve fixing support is connected with an embedded concrete reinforcement; the sleeve fixing support comprises a sleeve and a telescopic elastic cover; an internal thread or a revered tooth structure is arranged in the sleeve; the sleeve is fixed to the sleeve fixing support; and the telescopic elastic cover is propped against a concrete pouring formwork. According to such technical scheme, the anti-seismic lacing bar embedded part is embedded into the concrete without influence to the bracing of the concrete formwork, specifically the anti-seismic lacing bar embedded part is not needed to pass through the formwork, so that the formwork is convenient to brace and disassemble; the formwork has no requirement on hole drilling, so the formwork can be avoided being damaged during constructing; the anti-seismic lacing bar embedded part is served as an approved product which is manufactured according to the design dimension, so that the accuracy of the dimension is higher than that under the method of drilling the hole on the formwork or embedding ribs later; and the anti-seismic lacing bar embedded part can be used as a concealed project to be inspected and accepted together with a reinforcing steel project, therefore, the construction quality can be effectively ensured.
Description
Technical field
The present invention relates to a kind of concrete structure steel tie bar embedded part, particularly relate to a kind of Seismic Design of Reinforced Concrete Structure steel tie bar embedded part.
Background technology
In the anti-seismic construction technical measures of current architecture configuration engineering, mostly adopt tension rib to realize between concrete structure and the isostructural body of wall of masonry, these technical measures require that quake-proof steel tie bar one end is embedded in concrete structure, and the other end is embedded in masonry structure.For the building of masonry structure of constructing after concrete structure of first constructing, because template during concrete structure construction will be cut off tension rib, punching in template is adopted to realize penetrating the way of tension rib concreting again, template can be destroyed, template is caused to discard, substantially not adopt by construction party, and more be at present the way of planting after adopting tension rib, after plant construction method based on anchor-holding material bar planting, there is following problem in the way of this rear bar planting: 1, rear bar planting needs punching on concrete structure can destroy structure to a certain extent, 2, rear bar planting is easily encountered reinforcing bar and is caused hole to scrap when drilling operation, and make bar planting position occur change, 3, because tension rib is horizontal positioned substantially, bar planting hole is the level of state, liquid chemical Anchor Agent is not easy to fill, anchoring effect can be affected, 4, constructing operation more complicated, of poor quality, performance guarantee is relatively low.
Summary of the invention
In view of this, the technical problem to be solved in the present invention is, a kind of quake-proof steel tie bar embedded part is provided, pass through the technical program, to carry out installation pre-buried before construction concrete construction tension rib to be designed to built-in fitting, then after concrete construction completes during masonry construction by built-in fitting and the latter linked form of tension rib.Steel tie bar embedded part is constructed with the form supply of finished product accessory.
This technological invention solves the technical scheme that its technical problem adopts: a kind of quake-proof steel tie bar embedded part, comprise sleeve fixed support, described sleeve fixed support is connected with concrete embedded reinforcing bar, comprise sleeve and telescopic elastic cap, internal thread or pawl structure is provided with in described sleeve, described sleeve is fixed on sleeve fixed support, and the cap on described telescopic elastic cap is pressed in concreting template.
Described telescopic elastic cap is column or horn-like, be made up of adapter sleeve, shell covering, spring and cap, the shell covering that described adapter sleeve and flexible material are made is connected, and described spring is arranged in shell covering, and one end of described spring is pressed on cap; The adapter sleeve of described telescopic elastic cap is fixed on sleeve.
As the technical scheme optimized, when described telescopic elastic cap is horn-like, described Compress Spring is tower Compress Spring.
Described telescopic elastic cap is that telescopic elastic pipe is made, and one end of described telescopic elastic pipe is sleeved on sleeve, and the other end of telescopic elastic pipe is bonded with cap, and described cap is pressed in concreting template.
Described sleeve one end is set to cecum, has anchor slab or dowel in sleeve cecum arranged outside.Comprise sleeve fixed support, described sleeve fixed support is concrete embedded part, comprise sleeve and telescopic elastic cap, described sleeve is cylindrical tube shape, is provided with internal thread or pawl structure in sleeve, and described telescopic elastic cap is column or horn-like, be made up of adapter sleeve, shell covering, spring and cap, the shell covering that described adapter sleeve and flexible material are made is connected, and described spring is arranged in shell covering, and one end of described spring is pressed on cap; The adapter sleeve of described telescopic elastic cap is fixed on sleeve, and described sleeve is fixed on sleeve fixed support, and the cap on described telescopic elastic cap is pressed on concrete blinding.
Described sleeve one end is set to cecum, has anchor slab or dowel in sleeve cecum arranged outside.
In actual applications, described sleeve is fixed on sleeve fixed support with certain fixed form, telescopic sleeve cap is fixed on sleeve, the other end of telescopic sleeve cap is pressed on concrete blinding, the outer end of cap is made to be adjacent to template, cap is made to be directly exposed to concrete surface after form removable, thus can effectively avoid picking cutter for finding built-in fitting to concrete, screw thread has been made in sleeve, tension rib end is connected by screw thread, when making pawl structure in sleeve or sleeve lining roughening deformation process time, anchoring adhesive class Anchor Agent is full of in sleeve, tension rib is by pawl structure and inner wall coarse deformation process, to strengthen the connection effect using Anchor Agent, sleeve fixed support is together with sleeve connection, be used for fixing position and the spacing of sleeve.
The technique effect that the present invention reaches is as follows: a kind of quake-proof steel tie bar embedded part, be embedded in inside concrete, do not affect installing of concrete blinding, particularly template need not be passed, thus facilitate installing and removing of template, template need not be punched, thus the destruction avoided to template in construction, pass through the technical program, punch on concrete component without the later stage, thus the destruction avoided concrete component, quake-proof steel tie bar embedded part is as the approved product pressing design size making in advance, its dimensional accuracy is better than the accuracy of the way such as punching or rear bar planting in template.When quake-proof steel tie bar embedded part to count from substructure face size between first sleeve and structural plane because of to install etc. reason cause do not meet masonry modulus time, on this place's structural level, cement mortar can be increased or concrete way carrys out adjust size to meet modulus requirement.Quake-proof steel tie bar embedded part can carry out an acceptance inspection together with reinforced bar engineering as a concealed work, effectively can ensure construction quality.
