Abstract
A kind of steel structure net rack bar replacing apparatus, it is characterized in that: mounting flange is together with the end winding support of anchor tip, mounting flange and boss are takeed on and are fitted together by the respective inside and outside circle conical surface with it, boss shoulder is connected and fixed with the end of adjustable joint, adjustable joint and rod member are installed together in the mode of threaded engagement, at arranged outside moving flange of boss shoulder, be connected and fixed with set bolt between moving flange and mounting flange, the utility model has rigidity and intensity is all better; And the advantage of easy construction.
Description
Technical field
The present invention relates to steel structure net rack, be specifically related to steel structure net rack bar replacing apparatus, belong to steel structure net rack technical field.
Background technology
The rod member of grid structure, member bending (during pressurized) or rod member fracture (during tension) is there will be under excessive stresses effect, also the disconnected phenomenon of rust is there will be under corrosive environment, for ensureing that overall structure has the ability continuing carrying, meet normal using function, under normal circumstances the rod member destroyed is reinforced or replaced.
The method of existing rod member displacement is: removed by the rod member destroyed, then the rod member of complete (length cannot regulate) is used to carry out installation displacement, but there is following shortcoming in the method: 1, grid structure generation member bending or fracture, the spacing of two nodes of connecting rod will inevitably be caused to change, to bending rod member, two nodal point separation defections diminish, for the rod member broken, two nodal point separation defections become large, with existing method direct replacement, accomplish that part is changed in displacement and original rod member is isometric, very large External Force Acting is needed before displacement, the spacing of two nodes is adjusted to prerupture length, then replace, operation is difficult in Practical Project, 2, install for ease of displacement, generally all displacement rod member length is directly got the nodal distance after destruction, the length of this and original rod member is not etc.This can cause replaced after rod member stressed less or substantially do not stress, only play the effect of support, integral rigidity is difficult to be improved; 3, the method complicated operation, and be difficult to realize and design point identical, Practical Project is also difficult to apply.
In order to overcome defect existing in above-mentioned existing rod member displacement, also there is the length-adjustable rod member for grid displacement apparatus of rod member at present.Although this kind of rod member for grid displacement apparatus is to a certain degree planting the above-mentioned Problems existing of solution, but, because this kind of bar replacing apparatus is mainly regulated by the screw thread being arranged on rod member two ends, because the two ends at rod member arrange screw thread adjusting means, the intensity of rod member, rigidity the poor defect of existence and stability can be weakened to a certain extent, simultaneously, make in advance during bolt fixing hole due to flange position, two ends, be easy to make mutual dislocation between bolt fixing hole in the process of installing adjustment, cause construction peace just.
Summary of the invention
The object of the invention is to: for the above-mentioned defect existing for prior art situation, the invention provides a kind of novel steel structure net rack bar replacing apparatus, overcome above-mentioned defect existing in prior art situation.
The present invention realizes the technical scheme that above-mentioned purpose adopts: described a kind of steel structure net rack bar replacing apparatus, it is by anchor tip, set bolt, mounting flange, moving flange, adjustable joint, rod member, convex shoulder platform formed, it is characterized in that: mounting flange is together with the end winding support of anchor tip, mounting flange and boss are fitted together by the respective inside and outside circle conical surface with it between takeing on, boss shoulder is connected and fixed with the end of adjustable joint, adjustable joint and rod member are installed together in the mode of threaded engagement, at arranged outside moving flange of boss shoulder, be connected and fixed with set bolt between moving flange and mounting flange.
Use procedure of the present invention can be divided into following three kinds of situations to regulate:
(1) when between rod member, (that is: between two bolt sphere be connected) is without spatial position change, any load need not be loaded between rod member now, adjustable joint (5) now need only be regulated to make to keep close contact between the end face of convex shoulder platform (7) and mounting flange (3), and use set bolt (2) by fixing between mounting flange (3) and moving flange (4) simultaneously.
(2) when there is expansion situation in space between two rod members, now can apply the tension contrary with expansion trend, that is: regulate in advance adjustable joint (5) make to keep between the end face of convex shoulder platform (7) and mounting flange (3) between keep suitable distance, meanwhile, with set bolt (2), mounting flange (3) and moving flange (4) are fixed.
(3) with when there is the situation reduced in the space between two rod members, now, the compression contrary with the trend that reduces can be applied, that is: make to keep certain extrusion stress between the end face of convex shoulder platform (7) and mounting flange (3), and use set bolt (2) to be connected and fixed between mounting flange (3) and moving flange (4) simultaneously.
Wherein: being fitted together by the respective inside and outside circle conical surface with it of (7) takeed on by mounting flange (3) and boss, plays the effect of axis direction location.
According to requirement and the different behaviours in service of design and construction, between above-mentioned connector after installation is fixing, the method for welding can be adopted to be permanently fixed.
Beneficial effect: the present invention compared with prior art, has rigidity and intensity is all better; And the advantage of easy construction.
Accompanying drawing explanation
Fig. 1 is principle schematic of the present invention;
Shown in figure: 1 is anchor tip; 2 is set bolts; 3 is mounting flanges; 4 is moving flange; 5 is adjustable joints; 6 is rod members; 7 is convex shoulder platforms; 8 is inside and outside circle conical surfaces.
Detailed description of the invention
Composition graphs 1, the specific embodiment of the present invention is:
Described a kind of steel structure net rack bar replacing apparatus, it is by anchor tip (1), set bolt (2), mounting flange (3), moving flange (4), adjustable joint (5), rod member (6), convex shoulder platform (7) formed, it is characterized in that: mounting flange (3) is together with the end winding support of anchor tip (1), being fitted together by the respective inside and outside circle conical surface with it of (7) takeed on by mounting flange (3) and boss, boss shoulder (7) is connected and fixed with the end of adjustable joint (5), adjustable joint (5) and rod member (6) are installed together in the mode of threaded engagement, arranged outside moving flange (4) of boss shoulder (7), be connected and fixed with set bolt (2) between moving flange (4) and mounting flange (3).
Claims (1)
1. a steel structure net rack bar replacing apparatus, it is characterized in that: mounting flange (3) is together with the end winding support of anchor tip (1), being fitted together by the respective inside and outside circle conical surface with it of (7) takeed on by mounting flange (3) and boss, boss shoulder (7) is connected and fixed with the end of adjustable joint (5), adjustable joint (5) and rod member (6) are installed together in the mode of threaded engagement, arranged outside moving flange (4) of boss shoulder (7), be connected and fixed with set bolt (2) between moving flange (4) and mounting flange (3).
