Abstract
The utility model discloses a carbon fiber cloth reinforced steel pipe truss tubular joint which comprises a main pipe and a branch pipe of a reinforced node,wherein the branch pipe of the reinforced node is welded at the main pipe of the reinforced node so as to form the tubular joint; the carbon fiber cloth reinforced steel pipe truss tubular joint further comprises a plurality of pieces of carbon fiber cloth, which are formed by knitting fibrous bundles and plastic braided wires and glued layer by layer onto the main pipe of the reinforced node in the circumferential direction and the longitudinal direction in an overlapped manner, intersecting line profiles meshed with the tubular joints of the main pipe and the branch pipe of the reinforced node are respectively arranged on two short edges of the carbon fiber cloth at the tubular joints of the main pipe and the branch pipe of the reinforced node respectively, the pieces of carbon fiber cloth on the other parts of the main pipe of the reinforced nodein the circumferential direction are in end to end closed sticking, and the pieces of longitudinal carbon fiber cloth in the longitudinal directionare all uniformly glued into the reinforced region of the main pipe of the reinforced node. The static performance of the tube joint and the shock resistance and fatigue resistance performance of the joint are improved, and that the pipe truss structure has a higher load-carrying capacity, better earthquake resistance and longer service life can be ensured.
Description
Technical field
The utility model relates to the Welded Node of Steel Pipe Truss that a kind of carbon cloth (CFRP) is reinforced, and it is renovation reinforced that this reinforcing joint is applicable in the military service phase joint reinforcing and the node of welded pipe trussed construction, belongs to construction engineering technical field.
Background technology
At present, welding is passed through pipe node mutually because its graceful moulding and superior performance have been widely used in the large scale structure engineerings such as offshore platform structure, bridge construction and sports palace.For typical truss tubular joint, its arm generally bears axial force, moment of flexure and combining ability effect, therefore panel point mutually the supervisor at the place of passing through bear radial load, moment load and the combined load thereof that arm transmits, because node supervisor's radial rigidity is far smaller than the axial rigidity of arm, add toe of weld position and exist larger stress to concentrate and complicated residual stress, the supervisor of therefore passing through mutually position in panel point destroys the position being prone to most.In order to follow the basic principle of " the weak rod member of strong node ", generally need to pass through mutually position to the primary branch of panel point and reinforce, improve the anti-seismic performance of pipe node and improve its its static performance.At present, have for the conventional reinforcement means of pipe node: built-in stiffening ring reinforcing, the reinforcing of built-in plate, local thickening reinforcing, backing plate reinforcing, the reinforcing of collar extension plate and the reinforcing of adding rib plate etc.
All there is obvious shortcoming in above reinforcement measure, is mainly reflected in:
1, all need to weld with being reinforced node component, can be to impacts such as node cause that time damage, residual stress and stress are concentrated;
2, built-in reinforcing method difficulty of construction is larger, and reinforcing joint supervisor need to be cut, and can weaken supervisor's intensity;
Although 3, external reinforced method is constructed fairly simplely, can affect the usage space that even affects structure attractive in appearance of structure.
Utility model content
The purpose of this utility model is to provide the carbon cloth reinforced Welded Node of Steel Pipe Truss of a kind of use, and it is simple to operate, easy construction, cost are lower, be adapted at small space construction, and can not cause time damage to node.
In order to address the above problem, the technical solution adopted in the utility model is: the Welded Node of Steel Pipe Truss that a kind of use is carbon cloth reinforced, it comprises that being reinforced node is responsible for and is reinforced node arm, the described node branch pipe welding that is reinforced is being reinforced on node supervisor, and formation tubular joint, also comprise some blocks of carbon cloths, described carbon cloth is to weave by fiber bundle and plastic knitting line the haik type forming, described carbon cloth is reinforced on node supervisor along the hoop and the sticking on of longitudinal overlapping multilayer that are reinforced node supervisor, be positioned on two minor faces of the carbon cloth that is reinforced node supervisor and is reinforced node arm tubular joint place and offer respectively and be reinforced node supervisor and be reinforced the intersection profile that node arm tubular joint matches, the carbon cloth of the described hoop that is reinforced upper all the other positions of node supervisor all adopts end to end closed stickup, described longitudinal carbon cloth evenly sticks in the reinforcing area that is reinforced node supervisor, and the length of described reinforcing area is to be reinforced 3～4 times of node arm diameter.
Further, described in, being reinforced node supervisor and being reinforced node arm is round steel pipe or rectangular steel pipe.
Further, described intersection profile is arc notch.
Further, the length of the carbon cloth of described hoop is all than being reinforced the long 30mm of node supervisor's external diameter circumference.
The beneficial effects of the utility model are: this utility model can to the node of welded pipe trussed construction in the military service phase reinforce and node renovation reinforced, simple to operate, easy construction, the cost of this reinforcing joint be lower, be adapted at small space construction and can not produce the concentrated impact of damage, residual stress and stress to reinforcing joint; Can effectively improve pipe node its static performance and improve antidetonation and the anti-fatigue performance of node, and then guarantee that tube truss structure has higher supporting capacity, better anti-seismic performance and more permanent application life.
