Description

Technical Field

[0001] The invention belongs to the technical field of steel structure size detection equipment, and in particular relates to a device for quickly detecting the size of a U-shaped rib of a steel structure bridge. Background Art

[0002] Steel bridge is a bridge whose main load-bearing structure is made of steel. It has the characteristics of high strength and high rigidity. Compared with concrete bridges, it can reduce the beam height and deadweight. Prefabricated steel bridges have been widely used all over the world.

[0003] Due to the isotropy, uniform texture and large elastic modulus of steel, the working conditions of the bridge are consistent with the assumptions in the calculation diagram. In addition, steel bridges are generally prefabricated in factories and spliced ​​on site, with a short construction period, easy processing and no seasonal impact.

[0004] In the field of construction, steel structure bridges are increasingly showing their value. Due to their low cost, good structural performance, fast construction speed, good texture and strength, they are gradually being recognized by people. Steel structure bridges have developed rapidly and have replaced the rigid reinforced concrete structure bridges of the past to a certain extent.

[0005] The U-shaped ribs used in steel structure bridges are produced in factories. According to the requirements of QC / R9211-2015 standard, the size error of the U-shaped ribs of steel structure bridges is as follows: the allowable error of the opening width of the U-shaped rib is -1.0mm~+2.0mm, the allowable error of the bottom width of the U-shaped rib is -1.5mm~+1.5mm, the allowable error of the height of the two limbs of the U-shaped rib is -1.5mm~+1.5mm, the allowable error of the difference between the two limbs of the U-shaped rib is ≤2.0mm, and the allowable error of the lateral bending and vertical bending is <L / 1000 or 6 (the smaller value, L is the rib length). Therefore, after the U-shaped ribs of steel structure bridges are produced in the factory, their dimensions need to be tested so that the U-shaped ribs used in steel structure bridges meet the requirements of QC / R9211-2015 standard. The traditional method of testing U-shaped ribs is generally to use two angle squares and a ruler and two people to cooperate in the detection. Not only is the efficiency low, but it is also easy to cause large errors in the detection results due to insufficient human cooperation, thus affecting the quality of the later steel structure bridge construction.

[0006] Therefore, designing a rapid detection device for the size of U-shaped ribs of steel structure bridges to improve the detection efficiency of the size of U-shaped ribs of steel structure bridges and ensure the detection accuracy has become a technical problem that needs to be urgently solved by technicians in the relevant technical field. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a device for quickly detecting the size of U-shaped ribs of steel structure bridges, so as to at least solve some of the above-mentioned technical problems.

[0008] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0009] A device for quickly detecting the size of a U-shaped rib of a steel structure bridge comprises a U-shaped rib size detection plate for straddling and clamping on the U-shaped rib to be detected, a horizontal magnetic switch for detecting the horizontality of the U-shaped rib size detection plate, and a vertical magnetic switch for detecting the verticality of the U-shaped rib size detection plate; a U-shaped slot is provided on the U-shaped rib size detection plate, and the size of the U-shaped slot is consistent with the size of the outer wall of a standard U-shaped rib.

[0010] Furthermore, the U-shaped rib size detection plate is engraved with a U-shaped rib standard limb height line indicating the standard limb height of the U-shaped rib.

[0011] Furthermore, a vertically distributed center line is engraved on the U-shaped rib size detection plate, and the center line coincides with the center line of the U-shaped slot.

[0012] Furthermore, a first scale ruler distributed horizontally is provided on the U-shaped rib size detection plate, and an edge of the first scale ruler coincides with a standard limb height line of the U-shaped rib.

[0013] Furthermore, a second scale ruler distributed horizontally is provided on the U-shaped rib size detection plate, and the edge of the second scale ruler coincides with the standard limb height line of the U-shaped rib.

[0014] Furthermore, the 0 mark of the first scale and the 0 mark of the second scale both coincide with the center line, and the first scale and the second scale are arranged on both sides of the center line.

[0015] Furthermore, it also includes an angle ruler used to cooperate with the first scale and the second scale to detect the center deviation of the U-shaped rib to be detected.

[0016] Furthermore, the U-shaped rib size detection plate is made of stainless steel, and the thickness of the U-shaped rib size detection plate is 2-5 cm.

[0017] Furthermore, the top two corners of the U-shaped rib size detection plate are rounded structures.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The invention has a simple structure, a scientific and reasonable design, and is easy to use, and can effectively improve the detection efficiency of the U-shaped rib size of steel structure bridges and ensure the detection accuracy.

[0020] The invention mainly comprises a U-shaped rib size detection board, a horizontal magnetic switch, a vertical magnetic switch and a square. The U-shaped rib size detection board is provided with a U-shaped slot, and the size of the U-shaped slot is consistent with the size of the outer wall of the standard U-shaped rib. The U-shaped rib size detection board is engraved with a U-shaped rib standard limb height line, a center line, a first scale and a second scale. When in use, the U-shaped rib size detection board is straddled and placed on the U-shaped rib to be detected, and then the horizontal magnetic switch and the vertical magnetic switch are placed on the U-shaped rib size detection board, and the U-shaped rib size detection board is adjusted to be perpendicular to the length direction of the U-shaped rib to be detected. The opening width of the U-shaped rib can be judged by the gap between the outer wall of the opening end of the U-shaped rib to be tested and the corresponding side of the opening end of the U-shaped slot on the U-shaped rib size detection plate. If the size of the opening end of the U-shaped rib to be tested is larger than the standard value, the U-shaped rib size detection plate will not be installed in place. If the size of the opening end of the U-shaped rib to be tested is smaller than the standard value, the opening width of the U-shaped rib can be judged by the gap between the outer wall of the opening end of the U-shaped rib to be tested and the corresponding side of the opening end of the U-shaped slot on the U-shaped rib size detection plate. If the U-shaped rib limb is high, observe whether the upper end of the U-shaped rib to be tested is flush with the standard limb height line of the U-shaped rib. If they are flush, it meets the requirements. The bottom width of the U-shaped rib to be tested can be directly read from the first scale and the second scale and added. Fit the angle ruler from one side of the U-shaped rib to be tested with its outer wall, with the bottom end of the angle ruler flush with the open end of the U-shaped rib to be tested, and the ruler surface fits with the U-shaped rib size detection plate. The angle ruler and the scale on this side of the U-shaped rib size detection plate (such as the first scale) intersect, read the reading of the scale on the intersection at this time, and read the reading on the other scale (such as the second scale) in the same way. If the two readings are the same, the lateral bend and vertical bend meet the requirements. BRIEF DESCRIPTION OF THE DRAWINGS
