Description
Technical Field
The utility model relates to the technical field of building construction, in particular to a length-adjustable bailey beam nondestructive reinforcing vertical rod.
Background
The bailey frame is a truss unit consisting of an upper chord member, a lower chord member, a vertical rod and an inclined rod, can bear a pressure structure above, is formed by connecting a plurality of bailey frames through pin shafts, and is the most widely applied and best assembled bridge in China. Has the characteristics of simple structure, convenient transportation, quick erection, large carrying capacity, good interchangeability and strong adaptability
In the bridge construction process, the Bailey beam, the steel pipe pile, the pile top beam and the like form a temporary support system, the upper load is transferred to the Bailey beam, and then the Bailey beam is transferred to the pile top beam, the steel pipe pile and the like. Under ideal conditions, the upper part of the pile top beam is opposite to the vertical rod of the Bailey beam, but is limited by bridge span and site conditions, and in actual construction, the pile top beam is usually opposite to the chord member instead of the vertical rod, so that the shearing force of the lower chord member of the Bailey beam is overlarge, stress concentration occurs, and damage is caused. In order to prevent damage, vertical bar reinforcement is performed when installing the bailey beam. The conventional bailey beam reinforcing vertical rod needs to be welded with reinforcing accessories on the bailey frame, damage can be caused to the bailey frame, and the length cannot be adjusted.
Disclosure of Invention
The utility model aims to solve the defects of the prior art and provides a length-adjustable bailey beam nondestructive reinforcing vertical rod.
The utility model adopts the following technical scheme to realize the aim: the utility model provides a nondestructive montant of strengthening of bailey beam of adjustable length, includes the I-steel down, and fixed base is all installed at both ends around the I-steel top down, and fixed base is located both sides around the bailey beam web pole, and vertical steel pipe is welded at fixed base top, and adjustable jacking is installed at vertical steel pipe top, and adjustable jacking outside cover is equipped with the nut, and the I-steel is installed at adjustable jacking top.
Further, the fixed base is a channel steel, and the groove of the channel steel is larger than the lower I-steel.
Further, the adjustable jacking is arranged on the inner side of the top of the vertical steel pipe.
Further, the diameter of the cross section of the vertical steel pipe is 60mm.
The beneficial effects of the utility model are as follows: the utility model has the advantages of convenient and quick installation, no need of welding, reduced welding damage to the bailey beam, strong applicability by adjusting the jacking and the length of the reinforcing vertical rod, convenient installation and disassembly by adopting an assembled installation structure, and simultaneously avoids the phenomenon of stress concentration of the bailey beam at the beam of the pile top, and ensures the safety of the bailey beam.

Detailed Description
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
as shown in fig. 1-2, a length-adjustable bailey beam nondestructive reinforcement vertical rod comprises a lower I-steel 6, wherein fixed bases 5 are respectively arranged at the front end and the rear end of the top of the lower I-steel, the fixed bases 5 are positioned at the front side and the rear side of a web member of the bailey beam 7, vertical steel pipes 4 are welded at the tops of the fixed bases 5, adjustable jacking 2 are arranged at the tops of the vertical steel pipes 4, nuts 3 are sleeved outside the adjustable jacking 2, and upper I-steel 1 is arranged at the tops of the adjustable jacking 2. The fixed base 5 is a channel steel, and the groove of the channel steel is larger than the lower I-steel 6. The adjustable jacking 2 is arranged on the inner side of the top of the vertical steel pipe 4. The vertical steel pipe 4 adopts a seamless steel pipe with phi 60 multiplied by 4.5 mm.
And determining the installation position of the reinforcing vertical rod according to the design positions of the steel pipe pile 9 and the pile top cross beam 8, wherein the reinforcing vertical rod is positioned right above the pile top cross beam 8. The lower I-steel 6 is fixed on a lower chord member of the bailey beam 7, the fixed base 5 is welded with the vertical steel pipe 4 and is placed on the lower I-steel 6, the adjustable jacking 2 and the nut 3 are placed on the upper portion of the vertical steel pipe 4, pre-tightening is carried out firstly, after the upper I-steel 1 is installed, final tightening is carried out, so that the upper I-steel 1 and the lower I-steel 6 are respectively propped against the upper chord member and the lower chord member of the bailey beam 7, and the vertical reinforcement of the bailey beam 7 is realized. During the dismantling, only the nut 3 is required to be reversely rotated, the adjustable jacking 2 is loosened, the upper I-steel 1 and the lower I-steel 6 are pulled out, and the dismantling of the reinforcing vertical rod can be completed.
While the utility model has been described above with reference to the accompanying drawings, it will be apparent that the utility model is not limited to the above embodiments, but is intended to cover various modifications, either made by the method concepts and technical solutions of the utility model, or applied directly to other applications without modification, within the scope of the utility model.
