Abstract

The utility model discloses a kind of prefabricated PC node structure, and it is combined by prefabricated pile cover, precast beam, preserved pipeline, deformed bar, anchorage, grouting material and rubber blanket；Preserved pipeline is equipped with the prefabricated pile cover and the precast beam, cheated provided with anchor the port of the preserved pipeline, rubber blanket is set between the prefabricated pile cover and the precast beam, the rubber blanket is pasted onto on prefabricated pile cover, the deformed bar passes through the rubber blanket, the prefabricated pile cover and the precast beam, and locked with anchorage in the anchor hole of the precast beam, reaches the prestressing force of deformed bar design, anchor hole and preserved pipeline are blocked by grouting material again, form prestressed node.Advantage of the present utility model is that offshore construction does not need poured in place concrete, and node connection speed is fast.

Description

Prefabricated PC node structure

Technical field

It the utility model is related to port and pier engineering field, and in particular to a kind of prestressed node structure.

Background technology

Fabricated construction is that transportation industry develops irreversible trend, by sending out for many years in the construction of dock structure Exhibition, pile foundation, Liang Heban in high-pile beam dock structure all produce in precast plant substantially to be completed, and field cast-in-place node enters luggage Match somebody with somebody, assembly rate has reached 60%.But as assembling degree further improves, cast-in-place node has not adapted to high stake code The construction speed of head.Off-lying sea operation is particularly gone, because the high and artificial safeguard procedures of local labour cost require high, and it is existing to constructing The environmental requirement of field is relatively harsh, it is therefore desirable to the new node structure of utility model, solves the problems, such as cast-in-place node.With reference to the modern times The development of grouting technique, solves node connectivity problem using high-strength grouting material and deformed bar, thus proposes that assembled is pre- Stress node structure.

Utility model content

The purpose of this utility model is to provide a kind of prefabricated PC node structure, its by prefabricated pile cover 1, precast beam 2, Preserved pipeline 3, deformed bar 4, anchorage 5, grouting material 6 and rubber blanket 7 combine；

Preserved pipeline 3 is equipped with the prefabricated pile cover 1 and the precast beam 2, the port of the preserved pipeline 3 is provided with anchor Hole, rubber blanket 7 is set, the rubber blanket 7 is pasted onto on prefabricated pile cover 1, institute between the prefabricated pile cover 1 and the precast beam 2 State deformed bar 4 and pass through the rubber blanket 7, the prefabricated pile cover 1 and the precast beam 2, and cheated in the anchor of the precast beam 2 It is interior locked with anchorage 5, reach the prestressing force of the design of deformed bar 4, grouting material 6 blocks anchor hole and preserved pipeline 3, is formed pre- Stress node.

Preferably, the preserved pipeline 3 of the middle and upper part of precast beam 2 and deformed bar 4 set quantity to be more than bottom.Because At bearing, top is big by pulling force, lower compression power, so top configuration is more, bottom is few.

Preferably, the anchor hole and the upper and lower ends space of the rubber blanket 7 are all blocked using grouting material 6.

Preferably, the prefabricated pile cover 1 is erected in pile foundation.

Preferably, the preserved pipeline 3 is staggeredly reserved.

Beneficial effect：Advantage of the present utility model is that offshore construction does not need poured in place concrete, node connection speed Degree is fast, and assembling degree is high, reduces the measure cost of off-lying sea operating personnel's quantity and protection.

Embodiment

Embodiment 1

Referring to Fig. 1-3, a kind of prefabricated PC node structure, its by prefabricated pile cover 1, precast beam 2, preserved pipeline 3, Deformed bar 4, anchorage 5, grouting material 6 and rubber blanket 7 combine；It is all provided with the prefabricated pile cover 1 and the precast beam 2 There is preserved pipeline 3, the port of the preserved pipeline 3 is cheated provided with anchor, and rubber blanket is set between the precast beam 2 and prefabricated pile cover 1 7, the rubber blanket 7 is pasted onto on prefabricated pile cover 1；The deformed bar 4 passes through the rubber blanket 7, the prefabricated and of pile cover 1 The precast beam 2, and it is locked with anchorage 5 in the anchor hole of the precast beam 2, reach the prestressing force of the design of deformed bar 4, then Anchor hole and preserved pipeline 3 are blocked by grouting material 6, form prestressed node.

According to sequence of construction, prefabricated pile cover 1 and precast beam 2 first are produced in precast plant, on prefabricated pile cover 1 and precast beam 2 Good preserved pipeline 3 is reserved, rubber blanket 7 is pasted onto prefabricated pile cover 1, after prefabricated pile cover 1 is arranged in pile foundation, hung using crane ship Dress precast beam 2 is placed on prefabricated pile cover 1, is finely tuned prefabricated pile cover 1 and precast beam 2 relative position by jack, is made provided pipe Road 3 aligns, then wears deformed bar 4 and cross rubber blanket 7, prefabricated pile cover 1 and precast beam 2, and uses anchorage in the anchor hole of precast beam 2 5 locked deformed bars 4, and reach the prestressing force of the design of deformed bar 4, then grouting material 6 is poured into by grouting pump by envelope In stifled anchor hole and preserved pipeline 3, prestressed node is formed.
