Embodiment 2
As shown in Figure 7 and Figure 8, a kind of concrete component connection structure, including concrete component grafting disclosed by the invention
Connector further includes the first end plate 50 and the second end plate 51, and the plug connector 1 is fixed on the first end plate 50, the company
Female connector cylinder 2 is fixed on the second end plate 51, and first end plate 50 and the second end plate 51 are by being bonded or welded mutually
It is fixed, it is in particular fully welded and is fixed by steel bonding glue or edge.
In the present embodiment, the first end plate 50 and the structure having the same of the second end plate 51, as shown in figure 9, described
First end plate is equipped with the first fixation hole 500, and second end plate is equipped with the second fixation hole 510, in the present embodiment,
Due to the first end plate and the second end plate structure having the same, the label of the first fixation hole and the second fixation hole is same
It is labeled in one width figure, the plug connector 1 is threadedly secured on the first fixation hole 500, and the connection sleeve 2 passes through spiral shell
Line is fixed on the second fixation hole 510, and first end plate and the second end plate by welding or are adhesively fixed, and described second
Fixation hole is connected with Bar Anchorage hole by reinforcing bar slideway, and pear-shaped hole structure is formed.First fixation hole can be fixed with second
Hole is identical, is also possible to that threaded hole is separately provided between pear-shaped hole, and preferably the diameter of the first fixation hole is fixed less than second
Bore dia.
It is right according to the requirement of National Standard of the People's Republic of China's GB13476-2009 pretensioned prestressed concrete pipe pile
In the permissible variation in dimension of tubular pole, sloped-end requires to be less than 0.5%D, that is, end face can have certain error model always
Interior inclination is enclosed, the stake for being 500mm for stake end diameter, slant range will control within 2.5mm, then vertically driving piles
In the process, the sum of stake the end inclined possibility, that is, two stake end slant ranges of two docking will be within 5mm, also
To say in grafting, there may be gap between two stake end faces, plug can not grafting it is abundant, thereby increases and it is possible to have oblique cutting and not coaxial
The case where grafting is as shown in Figure 10 and Figure 11 mechanical splice in the prior art during plug connector is with sleeve grafting is connect
Occur due to plug connector with connect cause in the case of sleeve out-of-alignment grafting unsuccessfully schematic diagram, wherein x-x expression plug connector
Axis, y-y indicates the axis of connection sleeve, and as shown in Figure 10, the plug of plug connector 1 passes through intermediate nut 8 and seperated snap ring 5
Contact makes plug connector 1 to during connection sleeve grafting applying external force, the latch elder generation of downside and Plug contact, and upside
After latch with Plug contact, as shown in figure 11, the latch of lower part first with Plug contact and elasticity of compression under the action of plug
Part 9 therefore causes the latch deflection of two sides, when plug is further inserted into, such as Figure 11 with Plug contact after the latch on top
Shown, due to smaller with the inner wall spacing for connecting sleeve on the downside of plug, the latch of downside is further under the promotion of plug
Compression elastic piece and inner fovea part can cannot be introduced by plug ends limitation always, and on the upside of plug with the inner wall that connect sleeve
Spacing is larger, therefore the latch of upside enters inner fovea part under the promotion of elastic component, when removing external force, due to the latch of upside
Recessed portion is entered and has blocked plug, and the latch of downside does not enter recessed portion, and has existed when due to grafting between pile end plate
Certain gap, the latch of downside can not enter back into inner fovea part, or even angle tumble card occurs in sleeve, cause connection failure.
In addition, just as shown in Figure 10 and Figure 11, latch is in the effect of the elastic component of connection sleeve bottom in the prior art
Lower realization rebound and clamping, therefore in insertion process, it needs that latch is first pushed to generate certain stroke, the elasticity of compression in the axial direction
Part after being compressed to a certain degree, is just moved radially outward latch, allows plug to pass through the interstitial hole of seperated snap ring, this just increases
Add the axial stroke of latch during grafting, so that it is matched, need to be arranged longer plug, just it is able to achieve clamping, this
Since sample, in order to guarantee the intensity of entire plug, the taper of the taper type structure at the inner fovea part of plug will be relatively small,
Taper is smaller, and the gradient of the conical surface is smaller, then extraction gap is bigger after grafting, and extraction-resistant behavior is poorer.
In comparison, concrete component grafting connector disclosed in the present embodiment is optimized in the following aspects, solution
It has determined the above problem:
Firstly, being provided with correction chamber on the guide part of the present embodiment, while plug insertion, the position of plug is carried out
Correction reduces the offset of plug core axis to the full extent；Second, seperated snap ring described in the present embodiment is matched with guide groove
It closes, under chuck and the collective effect of guide part, guarantees that latch is caught in the inner fovea part of plug connector simultaneously, simultaneously because latch quilt
It is limited in guide groove, so that seperated snap ring can only slide along guide groove with plug connector contact process, pass through elastic ring
Axial screen resilience realize rebound, the guiding role of guide groove make seperated snap ring latch embrace be rolled on plug, under tension
When, play the role of further correcting, on the basis of correction chamber has completed correction to plug, further realizes plug equilibrium
Stress；Third, the present embodiment are oriented to seperated snap ring by guide groove, and the effect of elastic ring is cooperated to realize seperated snap ring
Opening and closing, during entire grafting, the axial stroke of plug is relatively short, and the taper of frustum at the inner fovea part of plug is set
Set bigger, taper is bigger, and the gradient of the conical surface is bigger, and extraction gap is small when stress after grafting, and extraction-resistant behavior gets a promotion.
Under above 3 points of the comprehensive function, concrete component grafting connector described in the present embodiment significantly promotes the success of grafting
Rate can guarantee the reliability of grafting completely.
Embodiment described above only describe the preferred embodiments of the invention, not to model of the invention
It encloses and is defined, without departing from the spirit of the design of the present invention, those of ordinary skill in the art are to technical side of the invention
The various changes and improvements that case is made should all be fallen into the protection scope that claims of the present invention determines.
