Climb the hinged securement structure of girder steel in a kind of tower crane
The utility model relates to the technical field of mechanical execution, climbs the hinged securement structure of girder steel in a kind of specifically tower crane, particularly its mechanical connecting structure.
Climbing girder steel in the climbing tower crane (abbreviation inside-climbing tower crane), be connected fixing with building generally be on shear wall, to stay hole to be provided; The flat built-in fitting that discharges water is buried in the bottom, hole; Or on beam, place built-in fitting; Then beam and built-in fitting are fixed, in climb frame and be fixed on the girder steel and realize climbing operation in the tower crane.Inside-climbing tower crane is positioned in the elevator or elevator hall of building usually, the mouth that punches on the shear wall in this method, and the main muscle in the hole is cut off, and also hurts sleeper sometimes, and building is had destruction to a certain degree, after tower crane climbs, reserves the hole and also wants filling-up hole.
Defective that exists in the comprehensive above-mentioned construction and construction hidden danger need further improve the fixed sturcture of existing inside-climbing tower crane.
Summary of the invention
The purpose of the utility model is to provide the hinged securement of climbing girder steel in a kind of tower crane structure; On shear wall, place built-in fitting in the construction, the hinged ear seat of welding on the built-in fitting, in climb the girder steel end and be designed to the articulated form that matches with built-in fitting; Link through bearing pin and shear wall; Need not to punch, avoided the main muscle in the hole is cut off, overcome the shortcoming and defect that exists in the prior art.
To achieve these goals; The technical scheme of the utility model is: the hinged securement structure of climbing girder steel in a kind of tower crane; It comprises building masonry wall, it is characterized in that: said over against the two sides building masonry wall in be equipped with built-in fitting, the built-in fitting end is equipped with two hinged ear seats; In climb main girder steel two ends be equipped with the monaural plate, in to climb the monaural plate at main girder steel two ends hinged with two hinged ear seats through bearing pin.
The utility model discloses the hinged securement structure of climbing girder steel in a kind of tower crane, this hinged securement structure avoids shear wall to punch mouthful to the injury of building, also without filling-up hole; Be convenient to construction; In climb girder steel displacement and install very conveniently, only need get final product with bearing pin is fixing, effectively reduce difficulty of construction; Improve operating efficiency, have good practicability.

The specific embodiment
With reference to the accompanying drawings, the utility model is further described.
The utility model is the hinged securement structure of climbing girder steel in a kind of tower crane; It comprises building masonry wall 1, and described building masonry wall is a shear wall, and the load-carrying capacity of shear wall will pass through designed and checked; Consolidation process in case of necessity; It is different from prior art and is: said over against two sides building masonry wall 1 in be equipped with built-in fitting 2, built-in fitting 2 ends are equipped with two hinged ear seats 3, the employing welding manner is connected between said built-in fitting 2 ends and the two hinged ear seats 3; In climb main girder steel 4 two ends be equipped with monaural plate 11, in climb main girder steel 4 two ends monaural plate 11 hinged through bearing pin 10 with two hinged ear seat 3.
In the specific implementation; Said two hinged ear seat 3 places are provided with bed plate 5, and bed plate 5 surface longitudinals are provided with two symmetrical otic placodes 6, and described otic placode 6 is provided with perpendicular to bed plate 5; The outside of two otic placodes 6 laterally is provided with 1-8 trapezoidal reinforcement gussets 7 respectively; A square edge of trapezoidal reinforcement gusset 7 is perpendicular to bed plate 5, and another square edge of trapezoidal reinforcement gusset 7 is perpendicular to having gap 8 between 6, two otic placodes 6 of otic placode; Two otic placode 6 places are provided with the otic placode axis hole 9 of symmetrical distribution respectively, and described bed plate 5, otic placode 6, trapezoidal reinforcement gusset 7 are into a single integrated structure.
In the specific implementation; The end of climbing main girder steel 4 in said is provided with the monaural plate 11 that matches with gap, two hinged ear seat 3 place 8; Monaural plate 11 both sides are equipped with the otic placode of transverse distribution and strengthen gusset 12; Monaural plate 11 places are provided with the monaural plate axis hole 13 that matches with otic placode axis hole 9, and described monaural plate 11 is into a single integrated structure with otic placode reinforcement gusset 12.
In the specific implementation; Said over against two sides building masonry wall 1 between be provided with two main girder steels 4 of the climbing of same horizontal surface that be parallel to each other and be positioned at; Climb in two be provided with between the main girder steel 4 two be parallel to each other in climb time girder steel 14; In climb time girder steel 14 two ends climb main girder steel 4 tops in being fixed in, in climb time girder steel 14 tops and climb frame 15 in being provided with.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the utility model practical implementation is confined to above-mentioned these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
