Description
Technical field
The present invention relates to Structures Reinforced Technique fields.
Background technology
Steel strand wires mesh sheet reinforcement technique is that steel strand wires mesh sheet is laid in the tensile zone for being reinforced component, then on its surface
Polymer mortar is smeared, being formed has certain whole compound cross-section for reinforcing layer thickness.Wherein steel strand wires are the main bodys of stress,
It is played in structure after reinforcing is higher than the tensile strength of regular reinforcement.In structure stress, pass through former component and reinforcing layer
It works together, can effectively improve its rigidity and bearing capacity.The reinforcement technique is to masonry structure brick wall, reinforced concrete structure
Beam, plate, column and node have good consolidation effect, and have " green " is environmentally friendly, intensity is high, dead weight is small, fire protecting performance is good etc.
Feature.
When the currently employed technology carries out strengthening of structural element, there are mainly two types of sides in end anchorage and tensioning for steel strand wires
Formula：First, steel strand wires end metal lantern ring is fixed by bolts in component surface, when using this method, the tensioning of steel strand wires is only
It manually can simply tense, stretching force tends not to meet the requirements, and stretching force deviation is larger from each other for steel strand wires, influences to construct
Quality；Second is that steel strand wires end anchorage is on shaped steel, shaped steel is fixed by bolts again in component surface, and this anchorage style can be with
Reach anchoring effect, when using this method, the tensioning of steel strand wires can only use single tendon stretch technology, and single tendon stretch power can be effective
The size of stretching force needed for ensureing, but inefficiency, increase construction period and difficulty.
Steel strand wires end anchorage is required for making in above two method, is unable to large-scale production application, steel strand wires
Stretching mode it is more original, steel strand wires stress is difficult to accurately control, and affects construction efficiency and construction quality, causes work indirectly
The raising of journey cost.If steel strand anchorage device that is easy and being applicable in construction site can be produced and more steel of simultaneous tension twist
Line and the tensioning equipment that can accurately control steel twisted-line tension-force can reduce Construction Cost and difficulty of construction, shorten construction
Period promotes economic benefit.
