Abstract

The utility model discloses a fixing device of a bridge guardrail metal stand column base. According to the fixing device, a leveling steel plate used for fixing the stand column base is arranged on a bridge guardrail steel reinforcement framework of a concrete structure, the leveling steel plate is provided with unthreaded holes corresponding to stand column base mounting holes, and two anchoring steel plates corresponding to the leveling steel plate up and down are symmetrically arranged below the top layer of longitudinal steel reinforcements of the steel reinforcement framework. Fixing bolts penetrate through the anchoring steel plates and are exposed out of the upper end of the leveling steel plate, the lower ends of the fixing bolts abut against a bridge girder surface layer, the leveling steel plate is welded on the steel reinforcement framework after being leveled, and then the leveling steel plate and a guardrail of a concrete structure are integrally formed in a pouring mode. According to the fixing device, metal stand column base holes are directly aligned to the exposed ends of the fixing bolts, nuts are screwed down at the exposed ends after stand columns are located, and therefore mounting is simple and fast. Due to the fact that the fixing device and the steel reinforcement framework are welded together, the metal stand columns are stably fixed and are not prone to being pulled out.

Description

The fastening devices of Bridge guardrail metal upright post base
Technical field
The utility model relates to Bridge guardrail, relates in particular to the metal upright post on the Bridge guardrail.
Background technology
At present, the beams of metal post fence is used constantly at bridge increases.Beams of metal post fence structure can effectively be protected errant vehicle, effectively reduces the probability that above-mentioned accident takes place, the loss that the minimizing accident causes, the traffic safety level of raising speedway.In addition, guard bar structure has from anti-dazzle function, can effectively save the antiglare shield expense, and the convenient LED lamp lighting device of installing of guard bar structure can effectively be saved the lamp stand expense simultaneously.
Because guardrail metal upright post opposing horizontal loading design load is bigger, whether except requiring base must have enough intensity, the rigidity, installing firmly also is the decisive factor of keeping beams of metal post fence side direction and vertical stability.Present mounting method is by pre-embedded bolt montant to be fixed on the protective guard, so install and fix not firmly, does not have enough holding capacity to resist external force such as wind-force, automobile impacting, is very easily blown down with external force by wind-force and extracts.
The utility model content
The utility model is exactly to have proposed a kind of simple and practical Bridge guardrail column base fastening devices at the problems referred to above.
For achieving the above object, the utility model adopts following scheme:
A kind of Bridge guardrail metal upright post base fastening devices, it is characterized in that, it is to settle a leveling steel plate that is used for the vertical columns base on the cage of reinforcement of Bridge guardrail concrete structure, the leveling steel plate is provided with the unthreaded hole corresponding with column base installing hole, two anchor plates of symmetrical placement below the top layer longitudinal reinforcement of Bridge guardrail concrete structure reinforcing bars skeleton, two anchor plates are corresponding up and down with the leveling steel plate, also be provided with the unthreaded hole corresponding with column base installing hole on the every anchor plate, the unthreaded hole of leveling steel plate is corresponding up and down with the unthreaded hole of anchor plate; Unthreaded hole by anchor plate is equipped with set bolt, nut on the set bolt is held the back set bolt to anchor plate and is exposed from the unthreaded hole of leveling steel plate, the lower end of set bolt withstands on the bridge main beam surface layer, is welded on the cage of reinforcement of concrete guardrail after the leveling of leveling steel plate; And then build with the concrete structure guardrail and to be integral.
For leveling steel plate and cage of reinforcement are connected firmly, with the bar dowel advance expenditure of the space of cage of reinforcement, by bar dowel the cage of reinforcement of leveling steel plate and concrete guardrail is welded together after the leveling of leveling steel plate.
Good effect of the present utility model is, erect when metal upright post is installed at protective guard, directly with the appearing of metal upright post base aperture secured in alignment bolt, after the stud location on appearing fastening nut get final product, so install simple and fast; Because this device and cage of reinforcement weld together, so the metal upright post fixation is difficult for being pulled out.
Description of drawings
Fig. 1 is the utility model elevation;
Fig. 2 is the utility model lateral view;
Fig. 3 is the utility model vertical view.
Among the figure: 1-leveling steel plate, 2-bar dowel, the top layer reinforcing bar of 3-cage of reinforcement, 4-anchor plate, 5-nut, 6-set bolt, 7-cage of reinforcement.
The specific embodiment
As Figure 1-3, Bridge guardrail metal upright post base fastening devices of the present utility model, be on the cage of reinforcement 7 of bridge concrete structure guardrail, to settle a leveling steel plate 1 that is used for the vertical columns base, leveling steel plate 1 is provided with the unthreaded hole corresponding with column base installing hole, two anchor plates 4 of symmetrical placement below the top layer longitudinal reinforcement 3 of cage of reinforcement, two anchor plates 4 are corresponding about in the of 1 with the leveling steel plate, also be provided with the unthreaded hole corresponding with column base installing hole on the every anchor plate 4, the unthreaded hole of leveling steel plate 1 is corresponding up and down with the unthreaded hole of anchor plate 4; By unthreaded hole set bolt 6 is installed, nut 5 on the set bolt 6 is held back set bolt 6 to anchor plate 4 and is exposed from the unthreaded hole of leveling steel plate 1, the lower end of set bolt 6 withstands on the bridge main beam surface layer, is welded on after 1 leveling of leveling steel plate on the cage of reinforcement 7 of concrete guardrail; And then build with the concrete structure guardrail and to be integral.
For leveling steel plate 1 and cage of reinforcement 7 are connected firmly, use bar dowel 2 advance expenditures of field fabrication after 1 leveling of leveling steel plate with the space of cage of reinforcement 7, by bar dowel 2 leveling steel plate 1 and cage of reinforcement 7 are firmly welded together.
