Abstract
The utility model discloses a steel case roof beam welding seam protector, including U type groove, magnet, magnet distributes at the lower tip on the U type groove both sides edge of a wing. Its simple structure of this device, magnet have passed through the magnetism principle and have attracted mutually with steel case roof beam mother metal, and it is convenient that the installation is dismantled, and device preparation low cost, U type groove and staving be as the receiving arrangement that welding spark and ceramic liner dropped, and it is efficient to have improved the welding, has reduced special messenger's work load on duty, has reduced construction cost.
Description
Technical field
The utility model relates to municipal technical field of bridge construction, is specifically related to a kind of steel box-girder weld seam protective equipment.
Background technique
Along with the needs of urban infrastructure development, the bustling major trunk roads in city are built viaduct express passway to be absolutely necessary trend, particularly in the steel box-girder viaduct Site Welding process of busiest section, city, steel box-girder main body butt joint all adopts ceramic substrate single face welding and double face shaping technology, due in welding process, ceramic substrate electric current when welding is heated or weld of reverse side stickup is excessive burns ceramic substrate, thus welding spark and weld seam ceramic substrate are dropped from high-altitude, this kind of situation often causes the injury to pass by one's way vehicle and personnel, there is larger potential safety hazard, during steel box-girder viaduct construction in the past, only take ground that interim isolating and protecting band is set, arrangement staff on duty is nursed, but this kind of mode easily causes traffic above-ground to block up, and the spark dropped in the air land after cause sputtering, welding spark can not protect completely and put in place.
Summary of the invention
The technical problems to be solved in the utility model is, in view of the foregoing defects the prior art has, provides a kind of steel box-girder weld seam protective equipment, prevents the device that welding spark and ceramic substrate drop, and this device is installed and convenient disassembly, can reuse.
The utility model for solving the problems of the technologies described above adopted technological scheme is:
Steel box-girder weld seam protective equipment, comprises U-type groove, magnet, and described distribution of magnets is in the underpart on the edge of a wing, U-type groove both sides.
By such scheme, described U-type groove outlet bottom is provided with staving.
By such scheme, described U-type groove is spliced by becoming several U-type groove unit seamless.
By such scheme, the U-type groove length of described element length 1.5 meters.
By such scheme, described U-type groove adopts colored steel watt to make.
The utility model has following beneficial effect:
This protective equipment is in the welding of busiest section steel box-girder viaduct, and its structure is simple, and magnet have passed magnetic principles and attracts mutually with steel box-girder mother metal, and installing/dismounting is convenient, and device fabricating cost is cheap; The reception unit that U-type groove and staving drop as welding spark and ceramic substrate, ensures the safety of below traffick and pedestrian, improves welding efficiency high, decrease the workload of staff on duty, reduce construction cost.

Fig. 2 is the elevational schematic view of Fig. 1;
Fig. 3 is the elevational schematic view of the utility model when steel box-girder viaduct skew web plate stands butt joint welding;
In figure, 1-magnet, 2-U type groove, 3-ceramic substrate, 4-base plate, 5-staving, 6-skew web plate.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
With reference to shown in Fig. 1 ~ Fig. 2, steel box-girder weld seam protective equipment described in the utility model, comprise U-type groove 2, magnet 1, described magnet 1 is distributed in the underpart on the edge of a wing, U-type groove 2 both sides; Magnet 1 have passed magnetic principles and attracts mutually with steel box-girder mother metal, the reception unit that U-type groove 2 drops as welding spark and ceramic substrate 3, ensures that U-type groove 2 is even by gravity, and not easily drops.
Described U-type groove 2 bottom outlet is provided with staving 5, and the welding spark that drops voluntarily and weld seam ceramic substrate 3 are pooled in staving 5 by U-type groove 2.
Described U-type groove 2 is spliced by several U-type groove 2 unit seamless of one-tenth.
U-type groove 2 length 1.5 meters (each U-type groove element length can be inconsistent) of described element length.
Described U-type groove 2 adopts colored steel watt to make.
Magnet 1 is single unit piece, and U-type groove 2 waste and old colored steel watt is made into the unit piece of 1.5 meter of one joint, and magnet 1 is whole piece, and consider that in U-type groove 2, foreign material are too much, U-type groove 2 bears incessantly self falling because of deadweight, need ensure the safety coefficient of U-type groove 2.
Working procedure of the present utility model:
U-type groove 2 is aligned in the back of weld bottom steel box girder bridge, magnet 1 whole piece is distributed in the underpart on the edge of a wing, U-type groove 2 both sides, by the magnetic principles of magnet 1 by ceramic substrate 3 reverse side being arranged in butt joint in good order for U-type groove 2, when the flat butt joint welding of steel box-girder viaduct base plate 4, welding spark and weld seam ceramic substrate 3 drop in U-type groove 2 voluntarily; When steel box-girder viaduct skew web plate 6 stands butt joint welding, below steel box-girder skew web plate 6, U-type groove bottom outlet is provided with a staving 5, the welding spark that drops voluntarily and weld seam ceramic substrate 3 are pooled in staving 5 by U-type groove 2, thus prevent from damaging the vehicle on road surface, below and pedestrian.
Above is only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalence change that the utility model claim is done, still belongs to protection domain of the present utility model.
