10 supporting intensity.
Strengthen on one end connection pile body stirrup 60 of main reinforcement 40, the other end for strengthening main reinforcement 40 is in 40-50 degree angle towards even
Binder 20 extends, and wears to the inside of linking beam 20；Strengthen supporting of the main reinforcement 40 to pile pile 10, Guan Liang 30 and linking beam 20
Degree more uniformly, also, more comprehensively can carry out supporting to the connector of Guan Liang 30 and linking beam 20, so as to be not easy it
Cracking.
The other end for strengthening main reinforcement 40 extends in 45 degree towards linking beam 20, and wears to the inside of linking beam 20,45 degree
When best angle；In this way, can supporting be carried out to the connector of Guan Liang 30 and linking beam 20 to the greatest extent, so as to be not easy out it
It splits.
Strengthening main reinforcement 40 has the anchoring section extended into inside linking beam 20, and the length of anchoring section is not less than 35mm；Effectively
Avoid anchoring section power insufficient, influence to strengthen the supporting effect of main reinforcement 40.
The both sides of linking beam 20 connect the pile pile 10 respectively, and above-mentioned construction technology is respectively adopted in two pile piles 10, this
Sample, the top of two pile piles 10 and the both sides of linking beam 20 can by the supporting for strengthening main reinforcement 40, in Double-row-piles Structure,
The both sides of linking beam 20 is effectively avoided to generate cracking with the connector of Guan Liang 30.
Pile pile 10 is equipped with pile body stirrup 60, and pile body stirrup 60 is used to surround pile body main reinforcement 11 and pile body main reinforcement 11 be played solid
Firm effect is determined, so as to enhance the overall stability of pile pile 10.
Furthermore for the ease of strengthen main reinforcement 40 install and stability, strengthen main reinforcement 40 one end be welded on pile body hoop
On muscle 60, in this way, under the action of pile body stirrup 60, strengthen main reinforcement 40 and form entirety with pile body main reinforcement 11, strengthen so as to enhance
The link stability of main reinforcement 40 carries out supporting so as to ensure to strengthen main reinforcement 40 to the connector of Guan Liang 30 and linking beam 20.
By the construction method of Guan Liang 30 and the connector of linking beam 20, after construction, formed double-row pile apical cap beam 30 with
The joint structure of linking beam 20.
The joint structure of double-row pile apical cap beam 30 and linking beam 20, including two 10 rows of pile pile, 10 row of pile pile is in a row-shaped, pipe
10 rows of stake include multiple pile piles 10, and multiple pile piles 10 are in a row-shaped arrangement；Guan Liang 30, two pile piles are connected at the top of 10 row of pile pile
It is connected between the Guan Liang 30 of 10 rows by multiple linking beams 20.
