Description

A kind of composite material connection jiont for net frame point and method
Technical field
The invention belongs to technical field of civil, relate to a kind of composite material connection jiont for net frame point and method.
Background technology
Along with the enhancing of China's economic strength and the urbanization process of population are accelerated, people get more and more to the demand of large-span space structure, require also improving constantly.As everyone knows, the building of certain form of structure built by specific constructional materials, and its span also exists a limit.Current long span building many employings steel, in built building, maximum span can reach more than 200 meter, this span limit of Gonna breakthrough, use fibre reinforced composites that are high-strength, lightweight, and choose reasonable space truss structure form is a kind of feasible approach.The multiple superior functions such as fibre reinforced composites have that specific strength is high, specific modulus is large, performance is easy to design, easily machine-shaping, anticorrosive, endurance, its application also enters civil construction field from Aero-Space, national defence again.
Civil construction field composite material section bar used take epoxy resin as matrix, with non-twist fiber for reinforcing material, adds particular/special requirement auxiliary agent simultaneously, make through pultrusion molding process.At present, the node connected mode of aviation field composite material has been continued to use in the connection of this field composite material section bar substantially: cementing connection, mechanical connection and the Hybrid connections of the two.Aviation field section bar used is layer paving section bar, and layer paving section bar can according to specifically stressed by multi-direction for fiber laying, to realize the most favourable stressed connection.But civil construction field section bar used mainly drawing and extruding section bar, drawing and extruding section bar machine direction is mainly along profile length direction, and the joint efficiency of this kind of section bar bolt connecting mode is lower than 30%, and section bar takes off destruction by cutting of the section bar that mostly occurs after bolt compresses.On the other hand, because the composite material section bar plate face of civil engineering field of traffic is thicker, according to cementing connected mode, for ensureing enough joint efficiencies, required lap length is comparatively large, and because construction problem can not realize enough lap length in more situation.Due to the jointly stressed of two kinds of connected modes can not be realized, cementingly can not to effectively improve with the joint efficiency of mechanical mixture jointing.
And composite material is less in the application in rack field, Main Bottleneck problem does not find suitable joint connecting method.Composite material due to rigidity less, at rack field many employings closed section, as composite tube cross section, composite material Box Section.At present, traditional connected node of this field composite material section bar, if the joint efficiency of cementing connection, mechanical connection and the Hybrid connections of the two is less than 30%, far can not play the advantage of composite material high strength degree.Have recently emerged the composite tube connected node that some are novel, its principle applies pretightning force mainly through butt joint and improves bearing capacity, and composite material creeping under heavily stressed continuous action is very serious, along with the carrying out of creeping, pretightning force can decline gradually, and bearing capacity also just cannot ensure.Also have some novel joints by drilling through screw thread at composite joint place, then connected by screw thread, this form improves bearing capacity to a certain extent, but place drills through screw thread at composite pipe joint, technique is more numerous, and has weakening to composite material tube section, in addition, this form is also only applicable to composite material circular pipe, and inapplicable to composite material square pipe.
Therefore, need a kind of composite material connection jiont for net frame point to solve the problem.
