Background
In the bridge erection process, a plurality of parts which need to be connected by high-strength bolts exist. The high-strength bolts are broken and fall, and certain risks exist for the condition that roads exist below the bridge. Although a certain safety margin is left when the bolt is calculated, in general, the bolt will not break. However, due to other factors, factors that cannot be considered by calculation may occur, resulting in breakage of the bolt. Today, there are also more and more situations in which bolt breaks occur on bridges. Security risks are also increasing. Therefore, a convenient and reliable bolt anti-falling structure is needed to be designed.
Today, the bolt anti-falling technology is still immature. The existing bolt anti-falling structure is arranged on a bridge before the bridge is formed. And the bridge body needs to be drilled or welded to finish the installation. Firstly, the workload is large; secondly, once installed, there is substantially no removability. When the bolts need to be overhauled and replaced, the bolts are quite inconvenient. In addition, many existing bridges which are formed into bridges do not have a bolt anti-falling structure, and the existing bolt anti-falling structure is not assembled on the existing bridges which are formed into the bridges. Therefore, there is a need to design a detachable bolt anti-falling structure.

the utility model provides a detachable bolt anti-falling structure, installs in the junction of two adjacent vertical beams, and the bottom pterygoid lamina butt joint of two adjacent vertical beams is fixed through two splint and mounting bolt from top to bottom, and the bolt anti-falling structure is including setting up respectively in two U-shaped fixed frames of adjacent vertical beam junction left and right sides, U-shaped fixed frame is including the symmetry setting up in the constitution angle steel of vertical beam front and back both sides, two constitute the bottom of angle steel passes through connecting angle steel fixed connection, two one side that constitutes the angle steel is close to each other is fixedly connected with connecting plate respectively, two one side that the connecting plate is close to each other can be dismantled respectively and is connected with the location angle steel that the level set up, the location angle steel is located the top of connecting angle steel, the bottom of location angle steel contacts with the top of the splint of pterygoid lamina upper end, two the anti-falling net is installed respectively to the bottom between the U-shaped fixed frame and both sides.
Further, the locating angle steel is provided with a plurality of through holes corresponding to the mounting bolts in a penetrating mode, and the locating angle steel is sleeved at the tops of the mounting bolts through the through holes.
Furthermore, the bottom ends of the constituent angle steels are connected with the connecting angle steels by welding, and the constituent angle steels are connected with the connecting plate by welding.
Further, the connecting plate is connected with the positioning angle steel through a fixing bolt.
Compared with the prior art, the utility model has the beneficial effects that:
1. the anti-falling bolt can be arranged on a bridge after the bridge is formed, so that the anti-falling function of the bolt is realized;
2. when the utility model is installed, the structure of the bridge is utilized for installation, the drilling or welding of the bridge matrix is not needed, and the bridge is not damaged in the installation process.
3. The utility model provides convenience for the overhaul and replacement of the subsequent mounting bolts for the detachable structure.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-4, a detachable bolt anti-falling structure is installed at the joint of two adjacent vertical beams 1, bottom wing plates 2 of two adjacent vertical beams 1 are butted and are fixed through an upper clamping plate 3, a lower clamping plate 3 and a mounting bolt 4, the bolt anti-falling structure comprises two U-shaped fixing frames which are respectively arranged at the left side and the right side of the joint of the two adjacent vertical beams 1, each U-shaped fixing frame comprises constituent angle steel 5 which are symmetrically arranged at the front side and the rear side of the vertical beam 1, the bottom ends of the two constituent angle steel 5 are fixedly connected through a connecting angle steel 6, one sides, which are mutually close, of each constituent angle steel 5 are respectively fixedly connected with a connecting plate 7, one sides, which are mutually close, of the two connecting plates 7 are respectively and detachably connected with a horizontally arranged positioning angle steel 8, the positioning angle steel 8 is positioned above the connecting angle steel 6, the bottom ends of the positioning angle steel 8 are contacted with the top ends of the clamping plates 3 at the upper ends of the wing plates 2, thereby the whole bolt anti-falling structure is hung on the wing plates 2 at the two sides through the positioning angle steel 8, anti-falling nets 10 are respectively installed at the two sides of the bottom ends between the U-shaped fixing frames, and the two sides are used for bearing the falling protection of the bolts 4, so that the falling risk is avoided.
In this embodiment, the anti-falling net 10 of the bottom surface is installed on the lower surface of the connection angle steel 6, so that a certain height difference exists between the upper surface of the connection angle steel 6 and the anti-falling net 10 of the bottom surface, and the connection angle steel 6 can play a role of a fence, so that the installation bolts 4 falling on the anti-falling net 10 are prevented from sliding from the left side and the right side of the anti-falling net 10.
