With connect side end face of the sleeve far from interior connecting screw hole.
In above-mentioned end-plate-free solid square pile connection sleeve, the lateral profile of the limit convex shoulder cross section is rounded,
Regular polygon or irregular polygon.
In above-mentioned end-plate-free solid square pile connection sleeve, the outer circumferential of the sleeve body is equipped with connection sleeve limit
Position portion.
In above-mentioned end-plate-free solid square pile connection sleeve, the connection sleeve position limiting structure is to be set to sleeve body
Outer circumferential several spaced limiting grooves.
In above-mentioned end-plate-free solid square pile connection sleeve, the connection sleeve position limiting structure is to be set to sleeve body
Outer circumferential several spaced positioning protrusion.
In above-mentioned end-plate-free solid square pile connection sleeve, the sleeve body and limit convex shoulder are integral type knot
Structure.
In above-mentioned end-plate-free solid square pile connection sleeve, the sleeve body is made of screw thread Steel material.
Compared with prior art, this end-plate-free solid square pile connection sleeve has the advantages that the following：
1. end-plate-free solid square pile connection tube-in-tube structure is simple, convenient for manufacture, instead of traditional end plate stake both ends
End plate reduces materials'use amount, reduces production cost.
2. an end-plate-free solid square pile connection sleeve setting limit convex shoulder can when connection sleeve is embedded in pile body both ends
To enhance the bite force between the connection sleeve and pile body, and in pile extension, enhance the anti-pressure ability of pile body end.
3. end-plate-free solid square pile connection sleeve can be used as connector when pile extension, other connectors is cooperated to realize
The pile extension of square pile.
4. an end-plate-free solid square pile connection sleeve will not be exposed in pile extension, will not be corroded by the external world, bonding strength is more
It is high.

Specific embodiment
Embodiment one
As shown in Figs. 1-2, this end-plate-free solid square pile connect sleeve, be embedded in the both ends of solid square pile and for it is solid
Main reinforcement both ends end thread connects in square pile, which is characterized in that this connection sleeve includes sleeve body 1, the sleeve body 1
The inner sidewall of one end is equipped with interior connecting screw hole 2, and the sleeve body 1 is equipped with far from one end of interior connecting screw hole 2 to be connected with outside
The outer connecting screw hole 3 of fitting connection, the aperture of the interior connecting screw hole 2 are more than or equal to the aperture of outer connecting screw hole 3.
Wherein, main reinforcement both ends outer circumferential is equipped with outer connection screw thread, one end of the sleeve body 1 in solid square pile
Inner sidewall be equipped with interior connecting screw hole 2.It is appreciated that being inserted between the connection sleeve and main reinforcement by above-mentioned main reinforcement end
It is threadedly coupled in interior connecting screw hole 2 and with interior connecting screw hole 2, to form mating connection.
In addition, the outer connecting screw hole 3 by being threadedly coupled with other connectors, specifically, cooperates at two
Connection sleeve on, being connected separately on corresponding outer connecting screw hole 3 being capable of mutually matched connector.
Further, the outer connecting screw hole 3 can be directly threadedly coupled with anchor bar, it will be understood that anchored
