Abstract
The utility model discloses a structure for preventing the deformation of a reinforcing steel plate welded at the upper wing edge of a crane beam, which comprises the reinforcing steel plate (2) welded at the upper wing edge of the crane beam (1), wherein at least three through holes (3) are arranged in the center line position on the reinforcing steel plate (2) in the length direction, the through holes (3) arranged on the reinforcing steel plate (2) are oval holes, and in addition, a space (L) between every two oval holes is between 200 and 500 mm. The utility model can effectively reduce and prevent the possibility of deformation generated while welding the reinforcing steel plate on the upper wing edge of the crane beam, and in addition, the utility model also has the advantages of simple structure and convenient construction.
Description
Technical field
The utility model relates to a kind of structure that prevents crane girder top flange weld reinforcement steel plate deformed, belongs to the crane girder welding technology field.
Background technology
At present, existing many crane girders can't attachment rail because design is narrow, could use behind the reinforcement steel plate of a broad of repair welding thereon, promptly directly the mode of reinforcement steel plate by common welding directly is welded on the top flange of crane girder, but when adopting existing method to weld, often make this reinforcement steel plate cause distortion because of welding, this not only can influence the installation of track, but also can influence the normal operation of crane.Therefore existing method at crane girder top flange weld reinforcement steel plate still is not ideal enough, can not satisfy the needs of use.
Summary of the invention
The purpose of this utility model is: provide a kind of structure that prevents crane girder top flange weld reinforcement steel plate deformed easy to operate, simple in structure, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: a kind of structure that prevents crane girder top flange weld reinforcement steel plate deformed of the present utility model, the reinforcement steel plate that comprises the top flange that is welded on crane girder, along its length position of center line place is provided with at least 3 through holes on the reinforcement steel plate.
Through hole on the above-mentioned reinforcement steel plate is an elliptical aperture, and the distance of being separated by between per two elliptical apertures is 200～500 millimeters.
Owing to adopted technique scheme, the utility model is provided with through hole on the reinforcement steel plate, the welding stress that is produced in the time of can not only eliminating welding so effectively, and can also prevent effectively that the reinforcement steel plate from deforming when welding.Therefore, the utility model compared with prior art, the possibility that the utility model deforms in the time of can not only reducing and prevent on the top flange of crane girder weld reinforcement steel plate effectively, but also have the advantage of processing ease, simple in structure, easy construction.
Description of drawings
Fig. 1 is welded on structural representation on the top flange of crane girder for reinforcement steel plate of the present utility model;
The be staggeredly arranged schematic diagram of Fig. 2 during for the upward view of Fig. 1 and for first step intermittent weld;
Fig. 3 is the plan structure schematic diagram of Fig. 1.
Description of reference numerals: 1-crane girder, 2-reinforcement steel plate, 3-through hole, 4-weld seam.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment of the present utility model: structural representation of the present utility model as shown in figures 1 and 3, when the top flange of existing crane girder 1 being carried out 2 welding of reinforcement steel plate, earlier along its length position of center line place produces at least 3 through holes 3 on reinforcement steel plate 2, through hole 3 on this reinforcement steel plate 2 preferably is made into elliptical aperture, also can be made into circular hole, the width of its elliptical aperture or the diameter of circular hole can be determined as required, generally can in 6～30 millimeters scope, select, the length of elliptical aperture can be selected in 10～60 millimeters scope, during making the distance L of being separated by between per two elliptical apertures is controlled at 200～500 millimeters; Then reinforcement steel plate 2 is placed on the top flange of crane girder 1 (as shown in Figure 1), between the both sides of the edge of the top flange of crane girder 1 and reinforcement steel plate 2, welds then, when welding, weld according to the following steps:
The first step, adopt intermittent weld, promptly between lateral edges of the top flange of crane girder 1 and reinforcement steel plate 2, weld out earlier a segment length and be 100～200 millimeters weld seam 4, and then to weld out another segment length between the opposite side edge of the top flange of car beam 1 and reinforcement steel plate 2 be 100～200 millimeters weld seam 4, the position of both sides weld seam 4 is staggeredly arranged (that is: the weld seam on both sides is not intersected with same straight line, this straight line is and the car beam perpendicular straight line of center line along its length), so replace welding on the both sides, top flange of car beam 1, the weld seam 4(that can weld out discontinuous like this between the both sides of the edge, top flange of crane girder 1 and reinforcement steel plate 2 as shown in Figure 2);
Second step, both sides replace repair welding, weld seam 4 etc. first step discontinuous all cools off back (welding stress is disappeared) naturally, respectively the discontinuities between the weld seam 4 of the discontinuous of the both sides of the edge, top flange of crane girder 1 is carried out the alternately repair welding of dual-side again, up to all residue sections all welding finish (as shown in Figure 3).
Claims (2)
1. structure that prevents crane girder top flange weld reinforcement steel plate deformed, comprise the reinforcement steel plate (2) of the top flange that is welded on crane girder (1), it is characterized in that: along its length position of center line place is provided with at least 3 through holes (3) on reinforcement steel plate (2).
2. the structure that prevents crane girder top flange weld reinforcement steel plate deformed according to claim 1 is characterized in that: the through hole (3) on the reinforcement steel plate (2) is an elliptical aperture, and the distance (L) of being separated by between per two elliptical apertures is 200～500 millimeters.
