Description
Technical field
The present invention relates to a kind of reinforcement means, particularly a kind of reinforcement means of grid structure bar.
Background technology
The rod member of space truss structure, under excessive stresses effect, there will be member bending (when pressurized) or rod member fracture (when tension), under corrosive environment, also there will be the disconnected phenomenon of rust, for guaranteeing that overall structure has the ability that continues carrying, meet the normal function that uses, under normal circumstances the rod member destroying is reinforced or replaced.
The method that existing space truss structure is reinforced:
1) rod member Shift Method: for the rod member needing reinforcement, when having ready conditions change rod member in the situation that, original rod member is replaced with to the suitable rod member in cross section; Another kind of mode is exactly to increase rod member at two Nodes.
2) increase bar cross section method: the method for increasing section is reinforced on former rod member, as increased steel pipe, angle steel, channel-section steel, reinforcing bar etc. to improve cross section and the radius of inertia of former rod member on former bar bar, and improves Anti-pull-press supporting capacity.
3) changed structural system method: on original structure, increase a kind of structural system (as arch, external prestressing tendon etc.), change the stress of original structure system, reach the object of reinforcing with this.
The shortcoming of existing space truss structure reinforcement means:
1) rod member Shift Method: space truss structure generation member bending or fracture, will inevitably cause two ball node spacings of connecting rod to change, to bending rod member, two ball nodes diminish apart from meeting, and to the rod member of breaking, two ball nodes become large apart from meeting.Accomplish to replace rod member and original rod member is isometric, before displacement, need very large External Force Acting, the spacing of two ball nodes is adjusted to prerupture length, and then replace, in Practical Project, be difficult to operation; Install for ease of displacement, general all displacement rod member length is directly got to the ball node distance after destruction, the length of this and original rod member is not etc.This can cause rod member after replaced stressed less or substantially do not stress, and original design can not coincide.
2) increase bar cross section method: joint steel pipe, angle steel, channel-section steel, reinforcing bar etc. on former rod member, common way adopts and is welded to connect.Be welded to connect and can produce welding residual stress in various degree, rod member, in localized hyperthermia's state, can have a strong impact on the stress of original rod member simultaneously, therefore higher to the technological requirement of welding, is difficult for meeting the demands.
3) changed structural system method: the method workload is large, wastes time and energy, and reinforcement cost is higher, and changed the stress of original system completely, before and after reinforcing, between original rod member and design bearing capacity, there is larger difference.The stress of all rod members all needs to analyze, and is not suitable for the engineering structures of local stiffening.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, and the reinforcement means that a kind of method is reasonable, can effectively improve the grid structure bar of strut bridging bearing capacity is provided.
