[0016] The utility model is described in detail and completely below in conjunction with the accompanying drawings. A person of ordinary skill in the art will be able to implement the utility model based on these descriptions. Before describing the utility model in conjunction with the accompanying drawings, it should be particularly pointed out that the technical solutions and technical features provided in each part of the utility model, including the following description, can be combined with each other without conflict.

[0017] In addition, the embodiments of the present invention involved in the following description are generally only a part of the embodiments of the present invention, rather than all of the embodiments. Therefore, based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0018] The following is a further detailed description of the utility model in conjunction with the accompanying drawings and implementations, and its specific implementation process is as follows:

[0019] like Figure 1 As shown, the utility model provides a construction hanger for a post-cast flange plate 1 of a high-speed railway box girder 2, comprising a plurality of hanger units, the plurality of hanger units being arranged at intervals along the longitudinal direction of the box girder 2, and the hanger units being used for installing the template of the flange plate 1;

[0020] The support beam 6 at the bottom of the hanger unit extends a certain distance to one end away from the flange plate 1 and is installed with a baffle 3, which can protect construction workers and prevent falling objects from high altitude. The extended ends of several hanger unit support beams 6 are connected by connecting beams 13, and steel panels 4 are fixed on the upper surfaces of the extended ends of several hanger unit support beams 6, so that the extended sections of the support beams 6 form a working platform area. In this embodiment, several hanger units are connected by connecting beams 13 to form a whole, thereby improving the integrity of the hanger units. At the same time, the connecting beams 13 and the supporting beams 6 are used as a whole to form a weighing skeleton, and a steel panel 4 is laid and installed on it to form a working platform area, thereby improving the functional attributes of the construction hanger. After the construction of the flange plate 1 is completed, the flange plate 1 needs to be painted. In the prior art, construction workers can only suspend the flange plate 1 from above through slings for painting. After the painting of this area is completed, the construction workers need to return to the top of the box beam 2 and reinstall the slings to paint the next area, which is time-consuming and labor-intensive. The present application uses the bottom area of ​​the hanger unit as a painting construction platform. The construction platforms between the hanger units are connected, and the construction workers can perform continuous painting operations, thereby greatly improving the construction efficiency.

[0021] The technical solution may also include the following technical details to better achieve the technical effect: the hanger unit includes a top beam 5, a support beam 6, an anchor rod unit 7 and a hanger rod unit 8;

[0022] The top beam 5 is spaced above the supporting beam 6, and the anchor rod unit 7 connects the top beam 5 with the box beam 2. In the present embodiment, two groups of anchor rod units 7 are provided, wherein one group of anchor rod units 7 connects the box beam 2 with the top beam 5, and the other group of anchor rod units 7 connects the top beam 5, the box beam 2 and the supporting beam 6; the suspension rod unit 8 connects the top beam 5 with the supporting beam 6.

[0023] The technical solution may also include the following technical details to better achieve the technical effect: the hanger unit also includes a plurality of support structures 9, which are arranged between the box beam 2 and the top beam 5 to support the top beam 5. In this embodiment, it is preferred to set two groups of front and rear support structures 9, which are arranged at intervals along the transverse direction of the box beam 2, and the two groups of support structures 9 form a front support point and a rear support point, wherein one support structure 9 is arranged close to one end of the flange plate 1, and the other support structure 9 is arranged close to one end of the top beam 5 away from the flange plate 1. The anchor rod unit 7 and the hanger rod unit 8 are both precision-rolled threaded steel anchors.

[0024] The present technical solution may also include the following technical details to better achieve the technical effect: the anti-slip pad layer 10 at the bottom of the support structure 9 improves the stability of the support structure 9 and prevents the support structure 9 from directly rubbing against the cast box girder 2 and damaging the surface of the box girder 2.

[0025] The present technical solution may also include the following technical details to better achieve the technical effect: a plurality of longitudinal beams 11 are arranged at the bottom between the hanger units, and the plurality of longitudinal beams 11 are arranged at intervals transversely along the supporting beam 6. The longitudinal beams 11 extend longitudinally along the box beam 2 to support the flange plate 1 and its formwork.
