Abstract
The invention belongs to building built-in part field, particularly relate to a kind of built-in fitting for underground exterior-protected structure, including spiral-lock helmet on built-in fitting exposed parts, being provided with the jack adaptive with described built-in fitting exposed parts in described helmet, the degree of depth of described jack is 2nd/to three/2nd of the thickness of described helmet；The thickness of described helmet is less than or equal to the thickness of ground-connecting-wall steel reinforcement cage, more than or equal to 3cm.Using the present invention, when ground-connecting-wall concreting, helmet keeps off outside built-in fitting exposed parts, concrete directly contacts with helmet, built-in fitting exposed parts is covered therein by helmet, it is to avoid directly contact with concrete, makes concrete can not stick on built-in fitting exposed parts.When construction in later period agent structure, only helmet need to be cut and built-in fitting can be made to expose, convenient and swift.In sum, patent of the present invention can make construction of underground structure ground-connecting-wall building enclosure built-in fitting be effectively protected, so avoid later stage a large amount of concrete cut workload, facilitate construction in later period.
Description
Technical field
The invention belongs to building built-in part field, particularly relate to a kind of built-in fitting for underground exterior-protected structure.
Background technology
The deep basal pit ground-connecting-wall building enclosure such as urban track traffic and building construction; substantial amounts of reinforcing bar connector or bent-up bar can be buried underground in the ground-connecting-wall construction stage; after steel reinforcement cage puts into ground-connecting-wall groove casting concrete; due to protective measure of not taking the initiative; later stage connect floor or bear down on one (foot) beam time; it is difficult to cut the concrete on built-in fitting surface, or embedded bar connector is filled real by concrete, and cause it to use.Along with the construction amounts such as China's infrastructure and building construction increase year by year, job site needs to design a kind of built-in fitting for underground exterior-protected structure the most urgently, cut work with avoid later stage a large amount of concrete, facilitate the connection construction of underground engineering later stage agent structure.
Patent of invention content
Patent of the present invention, for solving above-mentioned not carrying, the invention provides a kind of built-in fitting for underground exterior-protected structure, and this structure can facilitate the connection construction of underground engineering later stage agent structure.
Patent of the present invention is adopted the technical scheme that by solving technical problem present in known technology: a kind of built-in fitting for underground exterior-protected structure, this structure includes spiral-lock helmet on built-in fitting exposed parts, being provided with the jack adaptive with described built-in fitting exposed parts in described helmet, the degree of depth of described jack is 2nd/to three/2nd of the thickness of described helmet；The thickness of described helmet is less than or equal to the thickness of ground-connecting-wall steel reinforcement cage, more than or equal to 3cm.
Patent of the present invention has the advantages that
By using the structure of spiral-lock helmet on built-in fitting exposed parts, when ground-connecting-wall concreting, helmet keeps off outside built-in fitting exposed parts, concrete directly contacts with helmet, built-in fitting exposed parts is covered therein by helmet, avoid directly contacting with concrete, make concrete can not stick on built-in fitting exposed parts.When construction in later period agent structure, only helmet need to be cut and built-in fitting can be made to expose, convenient and swift.In sum, patent of the present invention can make construction of underground structure ground-connecting-wall building enclosure built-in fitting be effectively protected, so avoid later stage a large amount of concrete cut workload, facilitate construction in later period.
Accompanying drawing explanation
Fig. 1 is the structural representation of patent of the present invention；
Fig. 2 is the A portion enlarged drawing of Fig. 1.
In figure: 1, built-in fitting；2, built-in fitting；3, helmet.
Detailed description of the invention
Below in conjunction with the accompanying drawings patent of the present invention is described further.
Embodiment
As shown in Figure 1, 2, a kind of built-in fitting for underground exterior-protected structure, this structure includes spiral-lock helmet 3 on built-in fitting 2 exposed parts, being provided with the jack adaptive with described built-in fitting 1 exposed parts in described helmet 3, the degree of depth of described jack is 2nd/to three/2nd of the thickness of described helmet 3；The thickness of described helmet 3 is less than or equal to the thickness of ground-connecting-wall steel reinforcement cage 1, more than or equal to 3cm.The effect of built-in fitting is later stage attachment structure floor or bears down on one (foot) beam, the effect of helmet be protection built-in fitting not by concrete embedding, cut operation with avoid later stage a large amount of concrete.
The work progress of patent of the present invention: 1, be first according to design drawing and carry out the colligation of ground-connecting-wall steel reinforcement cage；2, carry out the colligation of built-in fitting or by spot welding, built-in fitting be connected with ground-connecting-wall steel reinforcement cage；3, holing according to the diameter of built-in fitting, the degree of depth is 2nd/to three/2nd of helmet thickness, is then enclosed within embedded bar by helmet.
In the present embodiment, described helmet 3 is made up of EPC, it would however also be possible to employ the flexible materials such as coiled material class make.Built-in fitting can be straight screw sleeve, it is also possible to be bent-up bar.
The operation principle of patent of the present invention: in the ground-connecting-wall steel reinforcement cage process segment; even after good built-in fitting; built-in fitting exposed parts buckles helmet protect; when pouring ground-connecting-wall concrete; the concrete at built-in fitting position directly contacts with helmet; during construction in later period agent structure, only helmet need to be cut and can expose built-in fitting.
Although the preferred embodiment of patent of the present invention being described above in conjunction with accompanying drawing; but patent of the present invention is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematically; it is not restrictive; those of ordinary skill in the art is under the enlightenment of patent of the present invention; in the case of without departing from patent objective of the present invention and scope of the claimed protection, it is also possible to make a lot of form, within these belong to the protection domain of patent of the present invention.
Utilize technical solutions according to the invention, or those skilled in the art is under the inspiration of inventive technique scheme, design similar technical scheme, and reach above-mentioned technique effect, all fall into protection scope of the present invention.
Claims (2)
1. the built-in fitting for underground exterior-protected structure, it is characterized in that, including spiral-lock helmet on built-in fitting exposed parts, being provided with the jack adaptive with described built-in fitting exposed parts in described helmet, the degree of depth of described jack is 2nd/to three/2nd of the thickness of described helmet.
