Selection of JL Inserts

At the selection of JL Inserts,please consider below factors and apply the minimum values.

① The bolt (Subject to SS400）
② The Insert
③ Concrete’s tensile strength

Please apply minimum values of ①②③ and fully consider the safety factors.

Concrete’s tensile strength in the chart is base on HANDBOOK of VARIOUS SYNTHE TIC CONSTRUCTIONDESIGN of Archtecural Institute of Japan.
Tensile strength = φ1× ×π×le(le+d)×0.313209（FC = N/mm2）
φ1＝ 0.6（short-term load）

Product Features

● It is inside threaded with a pin hole at its end for jointing reinforcing bars so as to prevent stripping and spread load evenly inside the concrete.

● When the countersunk plate is thin, joint reinforcing bars are used to carry some load, thus the inserts are not heavily-loaded.

● The length of joint bar need to be 10times longer than diameter of the joint bar. (It is recommended to be more than 20times longer.)

● Please use the bar of maximum diameter for pin hole

●Material：SD295A (SD345)

Application

Stripping of precast concrete plates, tumbling of heavy-duty concrete units, construction.
