Description

Rod member for grid composite consolidation device
Technical field
The utility model relates to the reinforcing technique field of rack Lack of support rod member, specifically a kind of rod member for grid
Composite consolidation device, mainly for rack overstressing rod member, slenderness ratio deficiency rod member, lengthening bar etc.
Background technology
The research of steel grid structure reinforcement means lags far behind the actual needs of steel grid structure reinforcing, and some new problems occurred in steel grid structure especially at present, just lack suitable method in current specification.Meanwhile, some new technologies, new method are not also applied in Elements of Space Grid Truss is reinforced.Carrying out reinforcing for the rod member not meeting load bearing requirements in Elements of Space Grid Truss is at present both economical and rational selection, and reinforcement mainly increasing section, but cross section increases deadweight also corresponding increase.In addition, when scene is to when being welded with strict restriction or not allowing welding, the application of these reinforcement means is just greatly limited, and causes component unsightly, does not catch up with the needs of social development.
Existing rod member for grid reinforcing technique, adopt outsourcing and treat the method for the isometric steel pipe of reinforcing network hack lever part or angle steel, there is following problem in the method: 1) rod member deadweight increases more, treating that reinforcing network hack lever part is Bao great Yi specification steel pipe or two panels angle steel, cause rod member to be conducted oneself with dignity to increase, if reinforced pole number of packages amount is more, overall structure must be caused to conduct oneself with dignity and to roll up; 2) adopt the method that is welded to connect to original structure by adverse effect, welding heat affected zone is treated the bearing capacity reinforcing rod member for grid and is had certain influence; 3) application of the method has limitation, in a lot of situation, does not allow or do not possess welding condition during structure of modification, such as petrol filling station or oil depot; 4) the method complicated operation, especially needs Site Welding, and the duration is reinforced in impact, is unfavorable for large-scale promotion application; 5) the method mainly relies on the solder technology of workman, and strengthening quality is larger by artifical influence factor.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of rod member for grid composite consolidation to fill
Put, allow reinforcement means become simple and convenient and practical.
The utility model realizes with following technical scheme: a kind of rod member for grid composite consolidation device, and comprise outside steel pipe and be arranged on for retraining the secure component of outside steel pipe on outside steel pipe, the diameter of outside steel pipe is greater than the diameter treating reinforcing network hack lever part; Described outside steel pipe is two semicircle steel pipes cooperatively interacted, and the inwall of each semicircle steel pipe evenly scribbles structure glue; Described outside steel pipe is arranged on the middle part for the treatment of reinforcing network hack lever part and length is less than the length treating reinforcing network hack lever part.
The beneficial effects of the utility model are: this device is simple to operate, and on-site consolidation is applied widely, can effectively improve reinforcing efficiency, effectively can reduce the very different quality control hidden danger brought of operator's technology.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A sectional view of Fig. 1;
In figure: 1, treat reinforcing network hack lever part, 2, structure glue, 3, outside steel pipe, 4, secure component.
Detailed description of the invention
As illustrated in fig. 1 and 2, a kind of rod member for grid composite consolidation device has an outside steel pipe 3 and is arranged on for retraining the secure component 4 of outside steel pipe 3 on outside steel pipe 3, and the diameter of outside steel pipe 3 is greater than the diameter treating reinforcing network hack lever part 1; Described outside steel pipe 3 is two semicircle steel pipes cooperatively interacted, and the inwall of each semicircle steel pipe evenly scribbles structure glue 2.Outside steel pipe 3 is arranged on the middle part for the treatment of reinforcing network hack lever part 1 and length is less than the length treating reinforcing network hack lever part 1.
The course of work: 1) according to treating the specification of reinforcing network hack lever part 1, stressed, the defect etc. that exists, calculate length needed for outside steel pipe;
2) usually choose than treating that the large specification steel pipe of reinforcing network hack lever part 1 is as outside steel pipe 2, in factory by outside steel pipe by Len req blanking, cut open;
3) spread structure glue 3 in the outside steel pipe 2 inwall painting cut open, structure glue 3 should be smeared evenly;
4) in time the steel pipe bag 2 cut open is being treated outside reinforcing network hack lever part 1, outside steel pipe 2 and the structure glue 3 treating between reinforcing network hack lever part 1 should fill closely knit, must not glue be leaked;
5) secure component described in is carbon cloth, after structure glue 3 is solid, wraps up in one deck carbon cloth outside outside steel pipe, plays constraint outside steel pipe 2, and making outside steel pipe 2 and wait to reinforce steel pipe 1 can better collaborative work;
6) secure component described in is clamp, wales outside steel pipe by clamp, and the quantity of clamp is determined according to the length of outside steel pipe 2, and the spacing between adjacent two clamps is not less than 200mm;
7), after having reinforced, check strengthening quality, as undesirable, reprocess in time.
The length of outside steel pipe is adopted and is calculated with the following method:
Curve differential equation is similar to according to depression bar calculate rod member Buckling Equation , k 2=F/EI, can calculate the position for the treatment of reinforcing network hack lever part critical strain point according to Buckling Equation, the part between corresponding two critical strain points, for exceeding the position of critical strain, takes outside steel pipe to reinforce to this part; Wherein y is the deflection deformation that compression member is corresponding, and x is compression member calculation level distance initial point length, and F is pressure, and E is modulus of elasticity, and I is dynamic moment of inertia, and A, B are the constant calculated according to fringe conditions.
After adopting this device, its fastening method is compared tool with existing method and is had the following advantages: 1) by calculating the length determining outside steel pipe, make rod member for grid field-hardened technology rationally more scientific; 2) outside steel pipe length is less than and treats reinforcing network hack lever part length, can save material, and reduces because reinforcing the space truss structure deadweight recruitment brought as far as possible; 3) the method on-site consolidation connects, and does not need welding, avoids welding and treats the adverse effect of reinforcing rod member for grid supporting capacity; 4) the method is simple to operate, on-site consolidation, applied widely, can effectively improve reinforcing efficiency; 5) the method effectively can reduce the very different quality control hidden danger brought of operator's technology.
