Abstract
The utility model discloses a kind of groove built-in fitting, including steel tank and the dowel being embedded in concrete, is provided with projection on the dowel surface.The end of described projection extends obliquely upward, and the angle between raised and dowel is 30 ° 60 °.The mode that steel tank is connected with dowel for welding or is riveted.The quantity of the dowel is at least provided with 3.The steel tank is c-type, and the inner surface of the opening of the C-type steel groove is inclined plane.Described dowel is processed into for screw-thread steel.The groove built-in fitting of this programme, dowel are up-narrow and down-wide trapezoidal, are embedded in mixed mud, can increase the tension pull out force in mixed mud, while also add weight capacity；Further, since the groove embedded part structure of this programme is simple, processing is more easy, reduces manufacture difficulty, reduces cost.
Description
Technical field
This utility model is related to a kind of connecting elements of building, more particularly to a kind of groove built-in fitting.
Background technology
Built-in fitting (prefabricated embedded part) is to install the component of (burying) in concealed work in advance, pacifies exactly when structure is poured
The component and fitting that puts, for building overlap joint during superstructure by laying bricks or stones, the installation for being beneficial to field engineering equipment Foundations is fixed.
At present, some traditional built-in fittings, such as groove built-in fitting, after being embedded into concrete, its tension pull out force is weaker, holds
Carry power weaker.
Utility model content
In view of this, there is provided the groove built-in fitting with stronger tension pull out force.
This utility model is realized using following technology：A kind of groove built-in fitting, including steel tank and is embedded in concrete
Dowel, including steel tank and the dowel being embedded in concrete, the dowel top connects steel tank, and bottom arranges round platform, described
Dowel surface is provided with projection, and the end of described projection extends obliquely upward, and the angle between raised and dowel is 30 ° -60 °.
The mode that steel tank is connected with dowel for welding or is riveted.
The quantity of the dowel is at least provided with 3.
The steel tank is c-type, and the inner surface of the opening of the C-type steel groove is inclined plane.
Described dowel is processed into for screw-thread steel.
The beneficial effect obtained using scheme of the present utility model is included：
Using the groove built-in fitting of this programme, dowel is up-narrow and down-wide trapezoidal, is embedded in mixed mud, can increase in mixed mud
Tension pull out force in soil, while also add weight capacity.
Further, since the groove embedded part structure of this programme is simple, processing is more easy, reduces manufacture difficulty, reduces
Cost.
Description of the drawings

Fig. 2 is this utility model side view.
Wherein 1- steel tanks, 2- dowels, 3- are raised.
Specific embodiment
For being further understood that this practical new feature and technology contents, refer to practical new detailed below in connection with this
Describe bright and accompanying drawing in detail, but institute's accompanying drawing is only provided and referred to and explanation, be not used for newly being any limitation as to originally practical.
This utility model is related to a kind of groove built-in fitting, and which includes steel tank 1 and dowel 2, and steel tank 1 is cuboid, and section is C
Type, opening up, bottom is connected with dowel 2.In addition, the steel tank 1 of c-opening, its inner surface is inclined plane, specially lean-in
Tiltedly, in hook-shaped, beneficial to other connector clampings.
Dowel 2 is connected with steel tank 1.Specifically, dowel 2 is made using screw-thread steel, and its lower end arranges a truncated cone-shaped, so
After in concrete of nuzzling and after condensation molding, which can prevent dowel 2 from outwards extracting.Further, steel tank 1 is connected with dowel 2
The mode for connecing for welding or is riveted, and in the present embodiment, the mode that steel tank 1 is connected with dowel 2 is welding.
In this utility model, raised 3 on described dowel surface, are provided with, specifically, raised 3 are arranged on dowel
On side surface, described raised 3 arrange some groups from top to bottom, and raised 3 end extends obliquely upward, between raised 3 and dowel 2
Angle be 30 ° -60 °.
In one embodiment, groove built-in fitting also includes that T-bolt (not shown), T-bolt are slided along the opening of steel tank 1
Dynamic.Specifically, the opening clamping of the T-shaped end of T-bolt and C-type steel groove 1, T-bolt can freely be slided and be adjusted.Due to
The inner surface of the opening of C-type steel groove 1 is inclined plane 11, in hook-shaped so that T-bolt is more tight with what steel tank 1 engaged.
In this utility model, 2 surface of dowel can also open up perforation, can also be provided with groove, in other words, on dowel surface extremely
Few setting perforation, groove or one of them of these three raised, further to increase the anti-pulling of groove built-in fitting and concrete
Power, structure are more firm.
In the present embodiment, dowel arranges 3, it is of course possible to which dowel can arrange multiple, adaptable steel as needed
Groove 1 can arrange specific length as needed.
As known by the technical knowledge, embodiment described above can be by other essence without departing from its spirit or essential feature
Embodiment realizing, therefore therefore can not be interpreted as the restriction to this utility model the scope of the claims.Therefore, disclosed above
Specific embodiment, for the person of ordinary skill of the art, is all merely illustrative, and can also have some deformations, not
It is that only the change in the range of this utility model of place or in equivalency range belongs to protection domain of the present utility model.
