Abstract
This utility model relates to a kind of pre-buried connection assembly for building, it includes that bottom is embedded in the attachment cap that in concrete and the connecting rod of concrete surface of emerging is threadeded with the upper end of connecting rod, particularly, the barb that the bottom with connecting rod is wholely set it is additionally provided with in concrete, wherein barb from the bottom of connecting rod to side or surrounding horizontal expansion, the most threaded in connecting rod have locking cap, and the upper surface of locking cap is mutually flush with concrete surface.This utility model setting by barb, it is possible to reduce the probability loosened between built-in fitting and concrete during construction, eliminate safe hidden trouble, meanwhile, can reduce loosening between built-in fitting and concrete in the case of attachment cap tension by locking cap.
Description
Technical field
This utility model belongs to building field, is specifically related to a kind of pre-buried connection assembly for building.
Background technology
At present, when concreting, use fastener inserts, its very common, but, especially for one end
Straight cutting, for the built-in fitting within concreting, once applies stress to built-in fitting or concreting part excessive, both
Between easily occur loosening, constitute great potential safety hazard.Meanwhile, for fixation steel plate time, attachment cap clamp force is excessive also
Easily cause built-in fitting loosening at inside concrete.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, it is provided that a kind of be not easy to loosen
Pre-buried connection assembly for building.
For solving above technical problem, this utility model adopts the following technical scheme that
A kind of pre-buried connection assembly for building, it includes that bottom is embedded in concrete and concrete surface of emerging
The attachment cap threadeded with the upper end of connecting rod of connecting rod, particularly, be additionally provided with in concrete with under connecting rod
The barb that end is wholely set, wherein barb from the bottom of connecting rod to side or surrounding horizontal expansion, in connecting rod
The most threaded have locking cap, and the upper surface of locking cap is mutually flush with concrete surface.
Preferably, locking cap includes locking cap body and is positioned at the packing ring above locking cap body, and the diameter of packing ring is more than
The diameter of locking cap body.
Preferably, barb extends horizontally.
Concrete, barb is curved or linearity is arranged.
Preferably, connecting rod and barb are reinforcing bar, and barb is welded on the bottom of connecting rod.
Additionally, attachment cap is double nut.This double nut includes upper cap nut body above, is positioned at the lower nut of lower section
Body, wherein the external diameter of upper cap nut body is less than or equal to the external diameter of lower nut body.
Due to the enforcement of technique scheme, this utility model compared with prior art has the advantage that
This utility model setting by barb, it is possible to loosen between minimizing built-in fitting and concrete during construction is general
Rate, eliminates safe hidden trouble, and meanwhile, can reduce in the case of attachment cap tension between built-in fitting and concrete by locking cap
Loosen.

Detailed description of the invention
Below by specific embodiment, this utility model is further described.
As it is shown in figure 1, the pre-buried connection assembly for building that the present embodiment provides, it includes that bottom is embedded in concrete
The attachment cap 3 that in the 1 and connecting rod 2 on concrete 1 surface of emerging is threadeded with the upper end of connecting rod 2, particularly,
Being additionally provided with the barb 5 that the bottom with connecting rod 2 is wholely set in concrete 1, wherein barb 5 is from the lower end of connecting rod 2
Portion is to side or surrounding horizontal expansion, and the most threaded in connecting rod 2 have locking cap 4, the upper surface of locking cap 4 and concrete 1
Surface is mutually flush.
In this example, locking cap 4 includes locking cap body 41 and is positioned at the packing ring 40 above locking cap body 41, packing ring 40
Diameter is more than the diameter of locking cap body 41.
Barb 5 extends horizontally.Meanwhile, barb 5 is uniformly distributed around the circumference of connecting rod 2.
Concrete, barb 5 is curved or linearity is arranged.In this example linearly.
Connecting rod 2 and barb 5 are reinforcing bar, and barb 5 is welded on the bottom of connecting rod 2.
Additionally, attachment cap 3 is double nut.This double nut includes upper cap nut body 30 above, is positioned under lower section
Nut body 31, wherein the external diameter of upper cap nut body 30 is less than or equal to the external diameter of lower nut body 31.
In this example, being provided with screw thread in connecting rod 2 upper end, the external diameter of upper cap nut body 30 is less than outside lower nut body 31
Footpath.
Above this utility model is described in detail, its object is to make the personage's energy being familiar with this art much of that
Solve content of the present utility model and be carried out, protection domain of the present utility model can not be limited with this, all according to this practicality
The equivalence that novel spirit is made changes or modifies, and all should contain in protection domain of the present utility model.
