And the way of considering usually is: behind the location, after particularly absolute altitude detects, beat horse immediately and eliminate steel plate gap, commissure, implement the discontinuous welding location, and then implement the integral solder of sections weld seam.This way, the technological operation complexity, effect is lower, and running into the tack welding position during integral solder needs to weld once more after excision earlier, the polishing, otherwise occurs defectives such as slag inclusion and pore easily.
Summary of the invention
The purpose of this utility model is in order to improve effect, guarantee alignment quality and weldquality simultaneously, a kind of Wavelike steel webplate positioning adjustment device is provided, this location Adjustment System is constructed, simple to operate, the Wavelike steel webplate degree of amplitude modulation is big, and good positioning effect significantly improves Wavelike steel webplate location and welding procedure effect.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of Wavelike steel webplate positioning adjustment device, it is characterized in that: respectively there is row's equal diameter circular hole the overlapping part centre that sections Wavelike steel webplate and sections Wavelike steel webplate to be installed have been installed, pass circular hole by the minor diameter bolt and be connected, the sections Wavelike steel webplate will be installed and sections Wavelike steel webplate to be installed connects as one with nut thread.
Described equal diameter circular hole is equidistantly arranged along sections Wavelike steel webplate short transverse being installed.
The first hole of described equal diameter circular hole and uropore be respectively apart from having installed sections Wavelike steel webplate top root edge 400mm, and the spacing between up and down between adjacent two circular holes is 500mm.
The aperture of described circular hole is 30mm, and the diameter of minor diameter bolt is 24mm.
The described circular hole both sides that sections Wavelike steel webplate and sections Wavelike steel webplate to be installed have been installed all are fixed with the bolt backing plate.
Be one by the fillet weld seam welding between the described link that sections Wavelike steel webplate and sections Wavelike steel webplate to be installed be installed.
The beneficial effects of the utility model are: when Wavelike steel webplate is installed, utilize the minor diameter bolt to pass the large diameter circular hole, utilize the simple and easy adjusting of the gap realization steel web between circular hole and bolt, steel web to be installed is carried out just connecting and just locating, spirit level detects steel web end absolute altitude, after meeting the requirements, the bolt that screws up with a wrench is eliminated the sheet separation, the beginning welding job, safe and reliable in the practical operation, simple and easy to do, help the assurance of steel web alignment quality and the significantly raising of construction effect.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is further specified.
Fig. 1 is a sections Wavelike steel webplate assembly unit schematic diagram;
Fig. 2 is the A place partial enlarged drawing of Fig. 1;
Fig. 3 is the fixedly structural representation of fillet weld seam of assembly unit end.
Among the figure: 1, concrete; 2, the sections Wavelike steel webplate has been installed; 3, sections Wavelike steel webplate to be installed; 4, circular hole; 5, bolt backing plate; 6, nut; 7, bolt; 8, fillet weld seam.
The specific embodiment
Embodiment 1
Shown in the utility model sections Wavelike steel webplate assembly unit schematic diagram of Fig. 1, the sections Wavelike steel webplate 2 of installing in the casting concrete 1 respectively has one to arrange equal diameter circular hole 4 with the overlapping part of sections Wavelike steel webplate 3 to be installed is middle, equal diameter circular hole 4 is equidistantly arranged along Wavelike steel webplate 2 short transverses, pass circular hole 4 by minor diameter bolt 7 and be threaded, sections Wavelike steel webplate 2 will be installed and sections Wavelike steel webplate 3 to be installed connects as one with nut 6.
When Wavelike steel webplate is installed, utilize the minor diameter bolt to pass circular hole, utilize the simple and easy adjusting of the gap realization steel web between circular hole and bolt, steel web to be installed is carried out just connecting and just locating, spirit level detects steel web end absolute altitude, and after meeting the requirements, bolt screws up with a wrench, eliminate the sheet separation, the beginning welding job.
Can suitably amplify the aperture of circular hole 4 or reduce the diameter of bolt 7 according to the amplitude of the required adjustment of Wavelike steel webplate.
Bolt 7 diameters should not because of the shearing that bolt opposing steel web deadweight in its first connection procedure produces, be avoided the failure by shear of the too small generation bolt of diameter less than 20mm.
The aperture of the default circular hole 4 of this example is 30mm, and the diameter of minor diameter bolt 7 is 24mm, and the gap between bolt 7 and the default circular hole 4 is 6mm like this; One row's circular hole 4 is set in the middle of the joint overlapping part of Wavelike steel webplate front and back end, and first hole and uropore be respectively apart from plate top root edge 400mm, and the spacing between up and down between adjacent two circular holes 4 is 500mm.
The pore size of circular hole 4 is calculated by the amplitude size that sections Wavelike steel webplate 3 to be installed needs to regulate.
The minimum diameter of bolt 7 is calculated by the shearing size that the deadweight of sections Wavelike steel webplate 3 to be installed causes.
Embodiment 2
As shown in Figure 2, circular hole 4 both sides that sections Wavelike steel webplate 2 and sections Wavelike steel webplate 3 to be installed have been installed all are fixed with bolt backing plate 5, come circular hole 4 is carried out shutoff by adding bolt backing plate 5, prevent that bolt 7 from coming off.
As shown in Figure 3, installed between the link of sections Wavelike steel webplate 2 and sections Wavelike steel webplate 3 to be installed and be welded as a whole by fillet weld seam 8.
Embodiment 3
The legal position adjusting of this macropore stove bolt Wavelike steel webplate construction procedure is as follows:
1) presets circular hole 4 in the Wavelike steel webplate precalculated position with setting before the construction;
2) utilize electric block lifting Wavelike steel webplate on the car of cantilever purlin, to position to be installed, transfer sections Wavelike steel webplate 3 to be installed, align with the default circular hole 4 in the end that sections Wavelike steel webplate 2 is installed in being embedded in casting concrete 1 along the track slippage;
3) behind the circular hole 4 cushioning bolt backing plates 5 with alignment, bolt 7 passes circular hole 4 and is threaded with nut 6, and this moment, nut 6 did not screw, and realizes location just.
4) just behind the location when detection absolute altitude and position and different design, start electric block, promote, fall or along bridge vertically before and after slippage sections Wavelike steel webplate 3 to be installed, until reaching designing requirement, tighten all bolts 7, nut 6 successively with spanner, adopt and use spanner fastening nut 6, to reduce lap gap in the standard permissible value.
5) behind sections Wavelike steel webplate to be installed 3 location, weld fillet weld seam 8 immediately, finish between the sections of steel web and connect.
Welding fillet weld in the above-mentioned steps was stitched 8 o'clock, taking " single face welding and double face shaping technology " is that 2 fillet weld seams 8 of the monolithic sections Wavelike steel webplate 3 to be installed and the interior outside that sections Wavelike steel webplate 2 junctions are installed are arranged a welder respectively, welding simultaneously from bottom to top, and keep the speed of welding unanimity, can avoid high temperature to cause the distortion of steel web.
Safe and reliable, simple and easy to do in the Wavelike steel webplate method of adjustment practical operation of the utility model macropore stove bolt method, help the assurance of steel web alignment quality and the significantly raising of construction effect.
