Description
Technical field
The invention belongs to building engineering field more particularly to a kind of prefabricated concrete structure node connection prefabricated component and its
Connection type.
Background technique
The node linked vector graph between concrete column and column mainly has sleeve connection and slurry anchor connection, existing sleeve at present
When connection, reinforced bar sleeve grouting connector is required to that grouting mouth and grout outlet is arranged in reinforced bar sleeve side wall, but since it is entirely poured
It infuses in precast concrete, is in the milk by exposing the grout pipe outside precast concrete, one side sleeve is cast in mixed
At solidifying earth pillar plastic hinge, since the ductility of sleeve and concrete is different, when vibration, which is easy to concentrate at sleeve both ends, is destroyed, separately
One side grouting quality causes grouting quality to decline vulnerable to the influence of the factors such as execute-in-place environment, can not detect in reinforced bar sleeve
Whether grouting material is filled, and causes the bonding strength of two in reinforced bar sleeve connection reinforcing bars not can guarantee, is further improved.
The mass for starching anchor node depends on the operation level of field worker, and quality of connection can not be verified one by one.
Summary of the invention
Goal of the invention: in view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of prefabricated concrete structure
Node connects prefabricated component.
The present invention also provides a kind of prefabricated concrete structure joint connecting methods.
The innovation of the invention consists in that the case where slurry can not be filled can be prevented, do not set at concrete column plastic hinge
Sleeve is set, it is more preferable to connect reliable anti-seismic performance.
Technical solution: in order to achieve the above object of the invention, the present invention is specifically achieved like this: a kind of assembled is mixed
Xtah Crude Clay structure node connects prefabricated component, including prefabricated upper truncated cylinder, prefabricated lower truncated cylinder, and prefabricated upper truncated cylinder, which is equipped with, runs through its length side
To and stretch out several reserved vertical muscle of its lower end surface, prefabricated lower truncated cylinder is equipped with through its length direction and stretches out end face thereon
Several lower reserved vertical muscle, lower reserved vertical muscle end is machined with external screw thread, and lower reserved vertical muscle end is machined with external screw thread, vertical steel
Upper reserved vertical muscle, lower reserved muscle of indulging are connected and are located at prefabricated upper truncated cylinder, lower section prefabricated with half grouting formula splice by muscle connection
Intercolumniation.Original connection sleeve is arranged at the plastic hinge of prefabricated upper truncated cylinder lower end, due to connection sleeve and prefabricated upper truncated cylinder ductility
Difference, cause easily to concentrate rupture from connection sleeve both ends when vibration, and now by half grouting formula steel of Vertical bar connection
Muscle connector is placed between prefabricated upper truncated cylinder and prefabricated lower truncated cylinder that not only quality of connection is good and shock resistance is more excellent.
Further, the Vertical bar connection includes connection sleeve, nipple, connector sleeve with half grouting formula splice
Cylinder inner wall is elongated to be machined with internal screw thread, and connection sleeve lower end is screwed on nipple, and nipple includes matrix, and matrix one end outer surface adds
Work has external screw thread, matrix other end machining internal thread hole, and nipple external screw thread is screwed on sleeve lower end internal screw thread is connect, internal screw thread
The external screw thread of hole and lower reserved vertical muscle end processing is screwed on fastening, and upper reserved vertical muscle is from connecting sleeve after being in the milk in connection sleeve
Upper end insertion.Cancel grouting mouth and grout outlet, and the structure that one end uses spiral to be screwed on, the other end uses grouting way,
It is tightly connected in sleeve and first fills material filling slurry, be then inserted into upper reserved vertical muscle from connection sleeve upper end, to guarantee that slurry fills
It is full, guarantee bonding strength.
Further, the prefabricated upper truncated cylinder is provided along its length through-hole.It can be incited somebody to action in hoisting prefabricated upper truncated cylinder
It passes through and is lifted in through-hole in rope, it is easy to operate.
Further, the through-hole is located at the center of prefabricated upper truncated cylinder, and through-hole is circular through hole and lower port is horn mouth.
When cast in situs, concreting face is not necessarily in same level, in order to guarantee that all prefabricated upper truncated cylinders are located at same water
It in plane, can adjust and stitch there are piece between prefabricated upper truncated cylinder and concreting face, is filled from grouting mouth in the prior art
Enter and fill piece, side pours into can be there are gap, so that bonding strength reduces.Slurry is now poured into out of top through-hole, under through-hole
End is horn mouth, so that slurry, which fills up, can preferably fill up edge joint position, bonding strength is stronger.
Further, further include two sections of Prefabricated superposed beams, two sections of Prefabricated superposed beams and prefabricated upper truncated cylinder, prefabricated lower truncated cylinder it
Between form node area, two sections of Prefabricated superposed beams are equipped with through its length direction and stretch out the reserved vertical muscle of level of its both ends of the surface,
The reserved vertical muscle of level between two sections of Prefabricated superposed beams is connected by reinforcing steel bar connecting sleeve tube.
A kind of prefabricated concrete structure node connection type, comprising the following steps:
(1) after prefabricated lower truncated cylinder, two sections of Prefabricated superposed beam splicings, spliced node area is filled up with concreting;
(2) several Vertical bar connections are screwed in half grouting formula splice stretch out prefabricated lower truncated cylinder upper surface it is several under
On reserved vertical muscle;
(3) prefabricated upper truncated cylinder is lifted on to the surface of prefabricated lower truncated cylinder, then is connect in Vertical bar connection with half grouting formula reinforcing bar
It is in the milk in the connection sleeve of head, several reserved vertical muscle insertion connections of prefabricated upper truncated cylinder lower end surface will be stretched out after grouting is full
In sleeve, make on the basis of the distance on ground when in upper reserved vertical muscle insertion connection sleeve according to prefabricated upper truncated cylinder upper surface
Prefabricated upper truncated cylinder lower end surface and concreting face form 1-4cm piece;
(4) piece surrounding is blocked with mortar, then be in the milk above through-hole, slurry terminates when overflowing from through-hole.
Beneficial effects of the present invention: compared with traditional technology, the present invention has the advantage that
1, upper reserved vertical muscle is connected with lower reserved vertical muscle with half grouting formula splice by Vertical bar connection in the present invention,
On the one hand it avoids former connection sleeve and is located at concrete plastic hinge level of breakage when causing to shake due to ductility inconsistent
Big situation, still further aspect can guarantee that slurry is filled;
2, it is convenient on the one hand to be lifted in the present invention by the through-hole on prefabricated upper truncated cylinder, on the other hand can effectively fill up spelling
Seam guarantees bonding strength;
3, installation difficulty is enormously simplified in the present invention, longitudinally connected length is adjustable.
