It should be noted that by be arranged on the outer wall of the lower column connecting pipe 2 first lateral projection 12 and it is described on
Second lateral projection 11 is set on the inner wall of column inner tube 6, and first lateral projection 12 and second lateral projection 11 are equal
It can be welded in advance in factory, therefore after cement slurry pours into the node and conserves molding, can greatly improve node
Longitudinal draw knot force, be particularly suitable in the pipeline of ocean engineering or the pillar of high-rise, because of two kinds of applied fields
Pillar in conjunction may due to wave or wind-force effect and by biggish load, and in skyscraper, top post
It may be similarly subjected to great pulling force at node, therefore need since wind-force or seismic factors are by by great pulling force
Want can the great node of tensile strength, can guarantee the safety of node, and node of the invention is due to being provided with described
One lateral projection 12 and the second lateral projection 11 when being used cooperatively with super high strength concrete, act on energy by mutual mechanical snap
Biggish tensile bearing capacity is enough provided, to guarantee that improving node has enough intensity.
It should be noted that the section of first lateral projection 12 and the second lateral projection 11 may each be it is round or
Rectangular protrusion can be welded on the outer wall of the lower column connecting pipe 2 by reinforcing bar coiling into shape is adapted to,
And it is welded on the inner wall of the upper prop inner tube 6.
In one embodiment, as shown in Fig. 2, the side lower end of the upper prop outer tube 5 is equipped with injected hole 13, upper end is equipped with
Starch hole 14.When to intra-node slip casting, ultra-high performance concrete slurry is injected from the injected hole 13, it is ensured that the high property of injection
Energy concrete slurry can fill the entire space of full node, then come out from the slurry outlet 14, can stop slip casting.
To achieve the goals above, the embodiment of the invention also discloses a kind of prefabricated concrete structure column steel pipe socket shell rings
The production method of point, includes the following steps:
Step 1, the lower column connecting pipe that outer wall is equably laid with to first lateral projection be welded in it is described under
On substrate, and open up on the lower substrate the vertical muscle of the lower substrate of the upper surface and the lower surface through the lower substrate
The lower surface of the lower substrate, is carried on the upper surface of lower prop by hole, and by the vertical muscle that the lower prop is reserved pass through it is described under
The lower substrate is bolted in the upper surface of the lower prop by the vertical muscle hole of substrate；It should be noted that described first is lateral
Protrusion is regular reinforcement, and is welded on the outer wall of the lower column connecting pipe, and above each step can be made in advance in factory
Make, and transported after factory makes to construction site, the vertical muscle that the lower prop is reserved passes through the vertical muscle of the lower substrate
The lower surface of the lower substrate is connected to the upper surface of the lower prop by hole, so, it is understood that the lower prop connection group
The in-site installation of part is very simple and efficient, significantly reduces field operation difficulty and labor intensity, and the scene of substantially increasing is
The efficiency of confession.
Step 2, the lower surface that the upper surface of the upper substrate of the upper prop connection component is connected to the upper prop, it is described on
The lower end of column outer tube is connected at the top surface edge of the lower substrate, and the lower column connecting pipe enters the upper prop inner tube
Inner space, the upper prop connection component are injected laterally ultra-high performance concrete slurry to form the node.
It should be noted that the upper prop inner tube welds the second lateral projection, second lateral projection is regular reinforcement,
And it is welded at the inside of the upper prop inner tube, above each step can be made in factory's pre-production in factory
It is transported later to construction site, is directly lifted on upper prop on the lower prop connection component together with the upper prop connection component, and
And it is fluted due to being arranged on the lower substrate, it is convenient for fixed and connects.
It should be noted that the upper prop connection component includes upper prop inner tube and upper prop outer tube, the upper prop inner tube be
Factory is welded in the upper prop outer tube in advance.
Connected it should be noted that the lower end of the upper prop outer tube of the upper prop connection component is inserted into the groove
It connects, the shape of the groove is in be adapted with the outer contour shape of the upper prop outer tube.So set, enabling to the upper prop
When connection component is lifted on the lower prop connection component, can be realized it is quick, accurate, position securely, in next step operate,
It gets ready.
It should be noted that the vertical muscle that can in advance reserve the lower prop makes external screw thread, the lower prop is reserved to be indulged
When muscle passes through the vertical muscle hole of the lower substrate, by the vertical muscle that the lower prop is reserved two stop nuts of configuration under described
Substrate is fixed, and the lower substrate is limited between described two stop nuts.Similarly, the upper prop is reserved in advance
Vertical muscle makes external screw thread, when the reserved vertical muscle of the upper prop passes through the vertical muscle hole of the upper substrate, by reserved in the upper prop
Vertical muscle on configuration two stop nuts the upper substrate is fixed, the upper substrate is limited in described two limit spiral shells
Between mother.
It should be noted that by the way that the first lateral projection and the upper prop is arranged on the outer wall of the lower column connecting pipe
Second lateral projection is set on the inner wall of inner tube, and first lateral projection and second lateral projection can exist in advance
Factory's welding, therefore after cement slurry pours into the node and conserves molding, it can greatly improve longitudinal drawknot of node
Power is particularly suitable in the pipeline of ocean engineering or the pillar of high-rise, because of the pillar in two kinds of applications
May due to wave or wind-force effect and by biggish load, and in skyscraper, top post may be due to
Wind-force or seismic factors are similarly subjected to great pulling force at node, it is therefore desirable to being capable of tension by by great pulling force
The node of intensity maximum can guarantee the safety of node, and node of the invention is due to being provided with first lateral projection
With the second lateral projection, when being used cooperatively with super high strength concrete, it is capable of providing by the effect of mutual mechanical snap biggish anti-
Bearing capacity is drawn, to guarantee that improving node has enough intensity.
It should be noted that the section of first lateral projection and the second lateral projection may each be round or rectangular
Protrusion, can directly be by reinforcing bar coiling into adapt to shape, be welded on the outer wall of the lower column connecting pipe, and weldering
It connects on the inner wall of the upper prop inner tube.
In the production method of prefabricated concrete structure column steel pipe socket shell ring point provided by the invention, significantly reduces and apply
Expenses of labour is used and difficulty of construction, substantially increases construction efficiency, simultaneously because upper prop connection outer tube through the invention is under
Column connects inner tube and forms the cooperation of the protrusion in cavity, also avoids avoiding using outer wooden template to construction auxiliary material
Waste.
The above disclosure is only a preferred embodiment of the invention, cannot limit the right of the present invention with this certainly
Range, therefore according to equivalent variations made by scope of the present invention patent, it is still within the scope of the present invention.
