Detailed Description
In order that the above-recited objects, features and advantages of the present utility model will be more clearly understood, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, however, the present utility model may be practiced otherwise than as described, and therefore the scope of the present utility model is not limited to the specific embodiments disclosed below.
Referring to fig. 1-4, in one embodiment of the present application, a quick reinforcing apparatus for a dual-limb pier body template is provided, including a pair of stay bars 6 and an ear plate 21 reserved for the pier body template, the pair of stay bars 6 includes a main rod member 4, two ends of the main rod member 4 are provided with nuts 3, the nuts 3 serve as two ends of the main rod member 4, the nuts 3 are internally threaded and connected with an adjusting screw 2, a bolt hole member 1 is fixedly connected on the adjusting screw 2, and a reserved hole 5 is provided in the middle of the main rod member 4.
In this embodiment, the opposite stay bar 6 is a main component, the main rod 4 of the main body part of the opposite stay bar 6 is a steel pipe, the two nuts 3 are welded and fixed with two ends of the main rod 4 respectively, and are connected into a whole, and the through holes of the ear plates 21 and the insertion holes of the bolt hole members 1 are used as connection points of the main rod 4 and the pier body templates.
Further, screw holes matched with the internal threads of the nut 3 are formed in the two ends of the main rod 4, and the adjusting distance of the adjusting screw 2 is further prolonged through the arrangement of the screw holes.
After the concrete is poured, the main rod 4 in the middle of the opposite supporting rod 6 is rotated to unload the force applied to the opposite supporting rod 6, and then the bolt 22 is removed, so that the opposite supporting rod 6 can be removed.
The split pier body template connected by the stay bars 6 has the functions of supporting and pulling simultaneously, so that the templates on two sides form a stable whole, the stay bars 6 are convenient to install and detach, the design requirement can be met by strictly controlling the spacing of the templates, and popularization and use are facilitated.
Further, as the members of the pair stay 6, the screw 2 and the nut 3 are adjusted, and the specifications of each of the members are the same.
