Description
Technical field
The utility model belongs to technical field of fixed buildings, discloses a kind of factory building height mid-span structure especially.
Background technology
For general individual layer steel-making continuous casting factory building, the continuous casting zone differs bigger with the factory building height in steel-making zone, generally has the discrepancy in elevation about 15-20m, and in factory building span direction, the horizontal total span of common whole factory building can reach more than the 200m, and total span is longer.When carrying out the design of factory building, according to " Code for design of steel structures " (GB50017-2003) requirement transverse expansion joint need be set.Usually the shrinkage joint is arranged between height strides, and reason has two: 1), for individual layer steel-making continuous casting factory building, in general height is striden and is positioned at whole horizontal middle part substantially; 2), just the place's of striding factory building roof absolute altitude differs bigger, the shrinkage joint is set also relatively rationally.
The processing mode at conventional shrinkage joint, as shown in Figure 1: the low factory building columns 1, height of striding striden low when twin columns are set and striden factory building columns 2, height and stride that height when twin columns are set is striden factory building columns 3 and height is striden factory building columns 4, be twin columns to be set in factory building horizontal span direction, the low roof girder of striding is supported on low factory building columns 1 and the height of striding and strides low striding on the factory building columns 2 when twin columns are set, and height is striden roof girder and is supported on height and strides that height when twin columns are set is striden factory building columns 3 and height is striden on the factory building columns 4.But, this processing mode, first relatively wastes steel; Second since twin columns are set certainly will will increase building area, strengthen construction investment; The 3rd deals with also relatively complexity.Therefore need seek the requirement that another mode of more optimizing satisfies the factory building transversal stretching.
Stride crossing place at height at present, the way of domestic majority is as shown in Figure 2: the low factory building columns 1, height of striding striden the factory building columns 5 and the height of unification and striden factory building columns 4, the low roof girder of striding is bearing in height with pin joint 9 slide hinged or direct articulated forms and strides on the factory building columns 5 of unification, and height is striden roof girder and is supported on height and strides the factory building columns 5 and the height of unification and stride on the factory building columns 4.This mode power transmission is fairly simple clear and definite, but its shortcoming is also arranged.If employing is hinged mode directly, then horizontal span is not just eliminated the measure of thermal stresses, so just needs consideration thermal stresses and the temperature deformation influence to the transverse frame structural internal force.Not only calculation of complex also can increase the factory building steel quantity consumption, causes waste.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, proposes a kind of factory building height mid-span structure.It is characterized in that: the factory building lower prop that height is striden the intersection is connected with the factory building upper prop of just striding the intersection by pin joint, height is striden roof girder one end and is connected on the pin joint of the factory building upper prop of just striding the intersection, the other end and height are striden factory building columns and are rigidly connected, and the low roof girder of striding is rigidly connected with the factory building lower prop of just striding the intersection with the low factory building columns of striding.The utility model has effectively solved the problem of temperature deformation, has played with the same effect in twin columns shrinkage joint, has reached the purpose of saving investment.The utility model structural system can be widely used in having in the steel-structure factory building of just striding.
Utilize factory building roof system difference of height to set up the effect that hinged steel stanchion plays the factory building transverse expansion joint.The utility model is striden the continuous pillar in discrepancy in elevation place with height and is processed into the hinged form in two ends (be commonly called as is the hinge toggle).When laterally having temperature to stretch, can play the effect of release temperature stress by the rotation of hinge toggle.
The utility model is compared with prior art:
(1) compare with traditional way, the transverse temperature that has effectively solved the bigger factory building of total span shrinks problem.
(2) compare with traditional way,, reduce building area, reduced the steel consumption amount because the lower prop of two adjacent temperature sections unites two into one.
(3) compare with traditional way,, reduced the internal force of just striding the adjacent upper prop because two ends are hinged.
The utility model proposes with the hinged steel column connection height in two ends and stride rigid frame, for the bigger industrial premises of total span, effectively solved the problem of temperature deformation, the advance that possesses skills and reliability.
Description of drawings: (because space of a whole page problem, height is striden each and only represented to stride the actual multispan that is)
Accompanying drawing 1 is striden the factory building processing mode for traditional height that twin columns are set;
Accompanying drawing 2 is striden post factory building columns processing mode for traditional low roof girder height that is articulated and connected of striding;
Accompanying drawing 3 is the utility model syndeton schematic diagram;
Accompanying drawing 4 is the utility model syndeton steel column connected node drawing.
Among the figure, 1 strides low when twin columns are set for height and strides factory building columns, 3 and stride height when twin columns are set for height and stride factory building columns, 4 and stride the factory building columns of unification for height for the high factory building columns, 5 of striding for the low factory building columns, 2 of striding, 6 for just striding the factory building lower prop of intersection, 7 for just striding the factory building upper prop of intersection, 8 is pin joint, 9 is pin joint, 10 for rotating double plate, and 11 stride roof girder, 12 for height connects, 17 is stiffening rib for bolt for rotating axillare, 16 for lower prop upper end, 15 for hinged steel stanchion, 14 for pin, 13
The specific embodiment:
