Description

Steel case roof beam U rib butt joint deviation detection chi

Technical Field

The utility model discloses a steel box girder U rib butt joint deviation detection ruler, and belongs to the field of steel box girder U rib matching condition detection.

Background

In recent years, with the rapid development of domestic and foreign traffic engineering, steel structure bridges also meet unprecedented development opportunities, and the steel structure bridges are reasonably utilized worldwide due to the advantages of high strength, light dead weight, short construction period, environmental friendliness and the like. Most of the steel box girder bridge deck slab and the bottom plate are stiffened by adopting U-shaped ribs, and the girder sections are connected by adopting a bolt welding combination mode. Generally speaking, as the steel box girder orthotropic bridge deck is subjected to repeated wheel load stress of passing vehicles, fatigue cracks are easy to appear at the joint position of the U-shaped rib, the U-shaped stiffening rib of the bridge deck is connected by adopting a high-strength bolt with better fatigue resistance, and the influence of the wheel load stress on the bottom plate is smaller, so that the U-shaped rib of the bottom plate is connected by adopting an embedding section. However, the requirement on the matching accuracy of the U ribs of the adjacent beam sections is high during the bolting of the U ribs, and the situation that the U ribs of the adjacent beam sections cannot be matched easily occurs. The specification requires that when the clearance of a friction surface is not more than 3mm, one side of a thick plate is ground into a 1:10 gentle slope, the clearance is smaller than 1mm, when the clearance of the friction surface is larger than 3mm, a base plate is added, the thickness of the base plate is not more than 3mm and at most not more than three layers, no specific detection tool is used for measuring the U rib butt joint deviation, or the used measurement method is not accurate enough, and the problem that the bolted U rib butt joint deviation is difficult to measure accurately is well solved. The steel box girder U rib butt joint deviation detection ruler is by the main scale, the scale draw-in groove, fastening screw, square nut, constitute such as magnet, the scale that uses mm as the unit is carved out on main scale and the scale, the main scale does not establish slide groove side 1/12 and 5/12 two installation magnet, it is firmly fixed with the main scale, the spout is all seted up to the main scale positive and negative, penetrate the scale in the scale draw-in groove, install the scale draw-in groove in the main scale positive spout again, square nut installs in the main scale reverse side spout, it is fixed with fastening screw, this detection ruler makes scale and scale draw-in groove be in the active condition through adjusting fastening screw, paste tight U rib salient side with the one end that the spout was not established to the main scale, adjust main scale opposite side scale, make the most advanced tight opposite side U rib that pushes up, fastening screw screws, take down the detection ruler and can accurately read out U rib butt joint deviation value.

Disclosure of Invention

The utility model aims to provide a detection ruler capable of accurately measuring the butt joint deviation of U ribs of a steel box girder.

In order to achieve the purpose, the utility model adopts the technical scheme that the steel box girder U rib butt joint deviation detection ruler comprises: the scale comprises a main scale 1, a scale 2, a scale clamping groove 3, a fastening screw 4, a square nut 5 and a magnet 6.

One side of the main ruler 1 is provided with a chute, and the other side is not provided with a chute; the top of the main ruler 1, which is not provided with the sliding groove, is provided with a plurality of small holes, the magnets 6 are placed in the small holes, and the main ruler 1 is fixed on the steel box girder through magnetic adsorption; the scale 2 is vertically clamped in the scale clamping groove 3, and the scale clamping groove 3 is in sliding fit with the sliding groove of the main scale 1; the fastening screw 4 connects the scale 2, the scale clamping groove 3, the main scale 1 and the square nut 5 together.

Furthermore, the magnet 6 and the small hole are fixed by glue.

Further, the whole that scale 2 and scale draw-in groove 3 constitute is installed in the main scale 1 openly spout, installs square nut 5 main scale reverse side spout department.

Furthermore, the U-rib scale structures consisting of the scale 2, the scale clamping grooves 3, the fastening screws 4 and the square nuts 5 are totally two, and the two U-rib scale structures are slidably mounted in the sliding grooves in the main scale 1.

Further, the scale on the main scale 1 and the scale 2 is in millimeters.

Compared with the prior art, the U-rib butt joint deviation detection ruler for the steel box girder, which is designed by the utility model, can accurately detect the U-rib butt joint deviation value through the matching of the main ruler and the ruler, can also detect other types of butt joint deviation, can be used as a ruler, has multiple purposes, and is convenient for construction detection of the steel box girder.
