Uniting Method of Temporary earth wall with basement exterior Wall using Couplers and Bolts.

摘要

The present invention utilizes the basement outer wall and shear connecting material to post-install the thumb pile (1) or CIP (2) constituting the temporary basement wall for the basement pit erection to be physically integrated to permanently demonstrate the composite strength .;H-beam thumb pile is to insert H-beam into bored hole and fill concrete into empty space, and CIP is to insert concrete after inserting rebar net into bored hole. It is a method to attach a coupler before insertion and integrate it with the basement outer wall to be constructed after gulting. The coupler is used to connect the bolts and tie bars that act as shear connectors. When pouring concrete into the boring hole, a temporary stopper 7 is attached to prevent the end of the free end of the coupler from being blocked with concrete.;After the excavation construction, clean the exposed surface of the thumb pile and CIP, find the position where the coupler is attached, remove the temporary stopper, turn the bolt to use as a shear connector, and construct the reinforced concrete outer wall as a joining wall. At this time, some of the couplers can be utilized for attaching the tie bar for the outer wall formwork if necessary. Naturally, the tie bar also serves as a shear connector as well as a bolt.
