Description

Technical Field

[0001] The utility model relates to the field of machining, in particular to a tooling device for an auxiliary positioning bracket for installing a temporary bridge support. Background Technique

[0002] During the installation construction of a steel structure bridge, there are often a lack of fulcrums and temporary supports are needed for auxiliary erection. After survey and design, the number of actual concrete columns on site is limited and the span is generally large. After the design of the steel structure bridge is completed, considering factors such as secondary deepening of the drawings, the actual situation of the production and manufacturing factory, the transportation route, and the on-site construction conditions, the bridge needs to be fabricated in sections and installed on site with the assistance of temporary supports, and finally the entire bridge erection can be reasonably completed in accordance with the design drawings.

[0003] The temporary bridge support is one of the essential equipment in bridge construction, which is used to support the bridge structure and plays a role in stabilizing and protecting the bridge during the bridge construction process.

[0029] The auxiliary positioning brackets for the installation of the temporary bridge brackets are usually the same for multiple projects. Except for the different main structures of individual bridges or the influence of environmental factors, specific auxiliary positioning brackets need to be fabricated. To meet the construction requirements, the auxiliary positioning brackets are generally in bolted connection form, which has higher precision and is easier to meet the on-site construction conditions.

[0030] The construction plan of the bridge bracket is an important link in the bridge construction process. Selecting suitable bracket equipment, operating strictly in accordance with the construction plan, and observing safety specifications can ensure the smooth progress of the bridge construction and guarantee the safety of construction personnel and passing vehicles.

[0031] Generally, when the height of the temporary bracket is less than 8m, one pair of auxiliary positioning brackets is used. When the height of the temporary bracket is greater than 8m, two pairs of auxiliary positioning brackets are used. At the construction site, after the auxiliary brackets are pre-fixed and installed on the temporary brackets, the temporary brackets are hoisted using lifting equipment. The auxiliary positioning brackets are composed of a crossbeam H-beam and the remaining channel steels. The baffle plate No. 2 and its corresponding main component are bolted, which is convenient for assembly and disassembly and is conducive to the adjustment of the verticality of the temporary bracket. It can be reused repeatedly during on-site construction.

[0032] Innovatively, each of the above effects exists independently, and a set of structures can also be used to achieve the combination of the above results.

[0033] It should be noted that the multiple solutions provided by this patent include their own basic solutions, which are independent of each other and do not restrict each other. However, they can also be combined with each other without conflict to achieve the co-realization of multiple effects.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and all these changes and improvements fall within the scope of the claimed invention.
