China Fully Threaded Steel Bar in Dia.75mm Grade

The steel bar can be screwed onto the connector with internal threads at any section or screwed with a threaded nut with internal threads for anchoring. The utility model has the advantages of simple connection and anchorage, strong adhesion, safe and reliable tension and anchorage and the like, and is a novel material for developing prestressed concrete component.

Experimental study of a novel precast prestressed

Feb 01, 2018 · After the test, the specimen was retrofitted by replacing mild steel bars and post-tensioned strands. The retrofit procedure is shown in Fig. 11. First, the mild steel bars and the replaceable angles are removed. Buckling of the mild steel bars in the part restrained by the column is observed (Fig. 11c). Then, the post-tensioned strands were Prestressed Concrete Prestressed Concrete ConcreteThis is typically defined as the "anchor head", which generally consists of a steel bearing plate, a hex nut and washer for a bar system, or a wedge plate and wedges for a strand system. For permanent ground anchors it is best to galvanize the hex nut and plates even if the bar is epoxy coated.

Tension Test for Axially Vibrated Prestressing Fine-Rolled

The interface between anchor plate and anchorage nut can be considered as a coupling spring whose stiffness is essentially the contact stiffness related to normal force at the contact surface, thus removing the usual assumption of fixed connection. The nut threads and steel bar are also connected with a coupling spring with the stiffness determined based on the threads treated as cantilever US3300922A - Anchor assembly for prestressed concrete US3300922A US373781A US37378164A US3300922A US 3300922 A US3300922 A US 3300922A US 373781 A US373781 A US 373781A US 37378164 A US37378164 A US 37378164A US 3300922 A US3300922 A US 3300922A Authority US United States Prior art keywords stressed anchor concrete bolt steel Prior art date 1964-06-09 Legal status (The legal status is an assumption and is not a legal Prestressing Steel Screw Bar for Prestressing Concrete
