Potential safety hazard.As the development degree of China's economic society is improved constantly, people use building the requirement of function and security
More and more higher, the function of Old building possibly cannot meet new use requirement, or because the requirement of early stage code of building design is low
And new design load demand can not be met, and while Old building use time is long, easily there are various damages, influence its safety
Property.In general, can be rebuild or maintenance, reinforcing two ways using removing when above mentioned problem occurs in existing building.Remove weight
That builds is with high costs, and a large amount of building wastes that are long in time limit and producing also have a strong impact on to environment；And consolidation process relative into
This much lower, short time limit, produces construction waste few, reaches under the premise of new use requirement and will not destroy the original structure of building
Form, therefore be widely applied in recent years.Frame structure is most widely used structure type in Civil structure, its
Bean column node is the key member of connection framework beam and frame column, is the important component for transmitting, distributing internal force, plays guarantee framework
The effect of structural intergrity, destruction of a node often results in the Progressive Collapse destruction of whole frame structure, and consequence is very serious.Cause
, for the concrete frame joint that there is potential safety hazard, it is very necessary to take certain reinforcement measure for this.
It is to improve the performance indications such as the intensity of node, rigidity, ductility that reinforced concrete frame node reinforces purpose.When
Preceding reinforced concrete frame node frequently with reinforcement means have reinforcement method of enlarging section, steel bonding/reinforced with external steel encased, paste fibre
Dimension cloth method for strengthening, anchor patch steel method for strengthening, prestressing, composite consolidation method etc..But these reinforcement means have accordingly
Advantage and disadvantage, such as when using reinforcement method of enlarging section, structure stress clearly, reinforcement performance reliability, but site operation wet trade
Time is more long, and production and living are had a certain impact, and reinforce after building headroom have certain reduction；Using steel bonding plus
Gu or during Strengthening by Steel-Packing, the strength and stiffness of node all improve a lot, but the bonding with epoxy resin as base-material for using
The durability of agent, ageing properties are all difficult to ensure that, the time is long may to cause the steel pasted to depart from；Anchor patch steel method for strengthening
Consolidation effect is preferable, but the damage comparison caused to former bean column node is big, when origin node reinforcement ratio is closeer, constructs more multiple
It is miscellaneous.Paste fiber cloth reinforced process simple, not the original size of concept transfer, fiber cloth has tensile strength very high and corrosion-resistant
Property, but the geometrical construction of existing node may cause the fiber cloth cannot effectively to paste and realize end anchorage so that fiber cloth
Performance cannot be not fully exerted.
