Description
Technical field
The utility model relate to a kind of utilize injection apparatus to prevent to be connected on steel structure bridge bolt or the device that comes off of Bolt, also can be used for preventing being connected to bolt in other Steel Structure Works or Bolt comes off.
Background technique
It is conventional technological means that the top of large-sized structural parts is undertaken being connected and fixed by bolt, but along with the prolongation of life time, prevention bolt falling, avoids damaging personnel, seems and is even more important.
At present, the measure of the bolt falling on large-scale steel structure link is prevented to be prevent bolt falling with bolt catch net around the rod member at firmly bolt or Bolt place.This measure needs first to calculate rod member size, produces catch net, then rod member at Bolt place was around Bolt one week, thus prevention bolt falling.Whole process makes trouble, and repeat usage is low, and cost is high, and construction gets up comparatively to bother, and necessary integral replacing during local damage, uses inconvenience; For the bolt on some special connection parts as bearing, comprehensive protective action can not be played.
Because the defect that above-mentioned existing bolt Drop-proof measure exists, the design people, actively in addition research and innovation, to founding a kind of structure of preventing bolt falling, make it have more practicability.
Model utility content
Main purpose of the present utility model is, overcome the defect that existing bolt Drop-proof measure exists, and provide a kind of structure of novel prevention bolt falling, simplify the operation operation, raises the efficiency, thus be more suitable for practicality, and have the value in industry.
The purpose of this utility model and solve its technical problem and realize by the following technical solutions.According to a kind of structure of preventing bolt falling that the utility model proposes, steel structural rod piece is connected by bolt, described bolt is multiple, the outer surface of described multiple bolt is provided with binding material, described binding material is wrapped in the outer surface of described multiple bolt uniformly, and binding material is the macromolecule polymeric material with thermoplasticity energy being added with epoxy resin.
Further, aforesaid a kind of structure of preventing bolt falling, described binding material is the list structure of many line compositions parallel to each other.
Further, aforesaid a kind of structure of preventing bolt falling, described binding material is multiple, is arranged on the outer surface of described bolt, is connected to form reticular structure mutually, or binding material forms continuous net-shaped structure in one week around steel structural rod piece.
Further, aforesaid a kind of structure of preventing bolt falling, when described bolt outer surface needs to prevent from getting rusty, can be provided with sealing place.
Further, aforesaid a kind of structure of preventing bolt falling, the distance between outermost two parallel lines of described binding material is less than the diameter of described bolt.
By technique scheme, a kind of structure of bolt falling of preventing of the present utility model at least has following advantages:
A kind of structure of preventing bolt falling of the present utility model by the outer surface at bolt by lance ejection one deck binding material, by being attached to the parallel lines of the different direction on bolt and nut, what bolt was adjacent is bolted together, the spacing of outermost two parallel lines is no more than the diameter of bolt, wherein binding material is that injection apparatus ejects three parallel lines, centre with the addition of the macromolecule polymeric material with thermoplasticity energy of epoxy resin, thermoplasticity polymer and steel have good cohesiveencess, be beneficial to and prevent bolt falling, also helpful to preventing the corrosion of bolt.Epoxy resin can improve quality and working life, cohesiveencess, pliability and the stability of high molecular polymer, can increase the cycle that guard is changed.If high molecular polymer guard, because needing to remove or change near working life or other reason, can be scratched with blade, take off, not damage steel, this device is easy to operate, cost is low, easily processes, and repairs also very convenient to the guard formed, also can spray local bolt and form sealing planar, prevent bolt corrosion, when the later stage is changed or removes, available blade is scratched, easily, harmless to steel.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.

Embodiment
For further setting forth the utility model for the technological means reaching predetermined model utility object and take and effect, below in conjunction with accompanying drawing and preferred embodiment, embodiment of the present utility model is described in detail as follows.
A kind of structural representation preventing bolt falling of the utility model, includes steel structural rod piece 1, bolt 2, binding material 3, steel structural rod piece bottom 4, steel structural rod piece top 5 and sealing place 6 as shown in figures 1-4.
Steel structural rod piece 1 is connected by bolt 2, and bolt 2 is multiple, and form Bolt, the outer surface of Bolt is provided with binding material 3, and binding material 3 is wrapped in the outer surface of multiple bolt 2 uniformly.Wherein binding material 3 is three parallel lines gone out by lance ejection, and the distance wherein between outermost two parallel lines is less than the diameter of bolt 2, and binding material 3 is for the addition of the macromolecule polymeric material with thermoplasticity energy of epoxy resin.Binding material 3 mutually between arranged in a crossed manner, form reticular structure, cross one another two with being 90 degree of angles between binding material 3.
After the binding material ejected by injection apparatus as shown in Figures 2 and 33 three parallel lines arrive steel structural rod piece 1 two ends, continue to be bonded in steel structural rod piece bottom 4 and steel structural rod piece top 5, subsequently around the another side to steel structural rod piece 1, be connected and be connected into line, overall formation reticular structure, links together bolt 2 independent of each other simultaneously.Wherein in order to prevent bolt 2 corrosion, also can spray local bolt and forming sealing place 6, as shown in Figure 4.
