Embodiment Construction
[0010] Such as figure 1 , 2 The box girder web fixing device shown includes two clamping plates 1, and 2 to 6 bayonets 3 perpendicular to the horizontal plane are arranged on the clamping plates 2 respectively, and the two clamping plates 1 are connected by pin shafts 2 , the whole is flip-chip π type; when used as image 3 First lay the upper panel of the main beam flat and install the small rib plate and the large partition 5, then assemble the web 4 to form an inverted π-shaped beam. After the web 4 is fabricated, the crane in the workshop is hoisted to the upper panel, and then the fixing device is spot-welded On the large partition 5, 4 sets of fixing devices are evenly distributed in the span direction of the main beam, and then the main beam web 4 is clamped in the bayonet 2 by using the pin shaft 2 and the rotatability of the fixing device, and then according to the The lines drawn on the upper panel will position the web 4.

The invention provides a device for fixing a box-shaped girder web and a using method thereof, belonging to the technical field of lifting devices. The device comprises two clamping plates on which 2 to 6 clamping holes vertical to the horizontal surface are arranged respectively; the two clamping plates are connected with each other by a pin shaft and form a shape like an inverted character Pi; when the device is in use, a small reinforced plate and a large clapboard are paved on an upper panel of a main girder; subsequently webs are assembled to form an inverted Pi-shaped girder and are hoisted onto the upper panel by a crane after being fabricated; subsequently the device is welded on a large clapboard in a spot welding way; four groups of fixing groups are uniformly arranged on the main girder in the spanning direction; subsequently the rotation characteristic of the pin shaft and the device are utilized so that a main girder web is clamped in a clamping hole; and subsequently the web is positioned by a line drawn on the upper panel in advance. By adopting the technical scheme, the time occupied by the crane in a fabricating site can be reduced greatly, the manpower and material can be saved, the product quality can be improved, a tool can be manufactured simply, used conveniently and utilized repeatedly, and the cost can be saved.
Description
technical field [0001] The invention relates to a box girder web fixing device and a using method thereof, and belongs to the technical field of crane equipment. Background technique [0002] When the main girder of the U bridge crane project is assembled in the workshop of the Sanli site, due to the large size of the web (6x1600x29000), the crane in the production workshop needs to be used during the assembly spot welding process until the assembly is completed. In this case, the crane in the production workshop The working hours inside are very long, and the assembly is relatively cumbersome. Contents of the invention [0003] In view of the defects in the prior art, the object of the present invention is to provide a box girder web fixing device and its application method which can reduce the working time of the crane in the workshop and facilitate assembly. [0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: box ...
