Embodiment Construction

[0050] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0051] Such as figure 1 As shown, the steel strands 13 are stretched simultaneously by using the center tensioning cylinders 14 on both sides of the bridge.

[0052] Such as Figure 2-Figure 6 As shown, the embodiment of the present invention proposes a piercing tensioning cylinder 14 of a bridge ferrule type tensioning system that uses a force sensor to display, measure and control the tension value, including a piston, a hollow force sensor 10, an outer ferrule 7. Inner ferrule tool anchor assembly 8, tool clip 12, wherein the far end of the hollow core force sensor 10 is fixed on the through-heart tension cylinder 14, and the proximal end of the hollow core force sensor 10 is fixed on the outer ferrule 7 and the proximal end of the outer ferrule 7 i...

Abstract

The invention provides a clip sleeve type tensioning system for a bridge built-in hollow force transducer and a method. A bridge clip sleeve integrated core penetrating tensioning oil cylinder comprises a piston, a hollow force transducer, an external clip sleeve and an inner clip sleeve tool anchorage; an remote end of the hollow force transducer is fixed on the core penetrating tensioning oil cylinder; the near end of the hollow force transducer is fixed on a remote end of the external clip sleeve; a near end of the external clip sleeve is detachably fixed on the inner clip sleeve tool anchorage; the inner clip sleeve tool anchorage center is provided with a hole for steel strand to pass through so that the steel strand is clamped and fixed in the inner clip sleeve tool anchorage hole through the tool clamping piece.

Description

technical field [0001] The invention relates to a bridge digital tensioning method and device for railway, highway and large-tonnage prestressed reinforced concrete tensioning construction, in particular to a bridge tensioning system and method for detecting and feeding back the tensioning force through a large force value sensor. Background technique [0002] In the production of prestressed concrete bridges, the post-tensioning method is commonly used to apply prestress: that is, the concrete bridge body is poured first, and after the concrete has strength, steel strands are inserted into the reserved tunnels of the bridge body, and A work anchor, a piercing tension cylinder and a tool anchor are respectively installed on the heads of the steel strands that protrude from both ends of the body. Then the steel strand is clamped by the tool anchorage, and the oil cylinders are started at both ends of the bridge at the same time. Driven by the tool anchorage, the steel strand ...
