Description
Technical field
The utility model relates to bolt field, refers more particularly to a kind of foundation ditch tool type guard rail fixing bolt.
Background technique
Existing tool type railing is fixing all adopts EXPANSION ANCHOR BOLTS, and construction EXPANSION ANCHOR BOLTS needs immovable point concrete to have certain intensity and thickness can fixation, and foundation ditch periphery sprayed concrete cannot meet this installation requirement.As adopted EXPANSION ANCHOR BOLTS scheme, foundation ditch periphery special construction must meet the concrete pier of EXPANSION ANCHOR BOLTS execution conditions, but concrete pier constructed after in order to meet requirement of strength, also need the curing time of a period of time; Therefore the mode of EXPANSION ANCHOR BOLTS is adopted often to need to manufacture cost of labor and the engineering time of a large amount of concrete pier at substantial.
Model utility content
The utility model is for above-mentioned defect, and provide a kind of foundation ditch tool type guard rail fixing bolt, this bolt comprises stud, connecting plate, reinforcing bar, and stud welding is in the upper-end surface of connecting plate, and reinforcing bar is welded on the lower end surface of connecting plate.
Further, described reinforcing bar is round steel or round steel pipe, and external diameter is 1.2 ~ 1.5 times of the nominal diameter D of described stud, and length is 300mm ~ 400mm, and lower end surface becomes 30 ° at vertical direction.
Further, described connecting plate is thickness 6mm ~ 10mm steel plate, and has the tapped hole of M8x1.25 at four drift angles of connecting plate.
The utility model compared with prior art, have tool type railing to fix not need to manufacture concrete pier specially, because this bolt is easy to use, good environmental adaptability, greatly can improve the efficiency that construction fixed by tool type railing, this bolt manufacture is simple simultaneously, cost is low, serves positive promoting effect to whole engineering construction, effectively reduces the cost of production of engineering.
Accompanying drawing explanation
Fig. 1 is that master of the present utility model looks and schematic top plan view;
Description of symbols in figure: 1 stud, 2 connecting plates, 3 reinforcing bars, 4 tapped holes.
Embodiment
Below with reference to accompanying drawing, the utility model is elaborated, so that those skilled in the art understand better and implement the utility model.
As shown in Figure 1, the foundation ditch tool type guard rail fixing bolt of the utility model indication comprises stud 1, connecting plate 2, reinforcing bar 3, and stud 1 is welded on the upper-end surface of connecting plate 2, and reinforcing bar 3 is welded on the lower end surface of connecting plate 2; More specifically, reinforcing bar 3 is round steel or round steel pipe, and external diameter is 1.2 ~ 1.5 times of the nominal diameter D of described stud, and length is 300mm ~ 400mm, and lower end surface becomes 30 ° at vertical direction; During to realize construction be convenient to this bolt to beat into soil horizon, and play good fixation.Further, connecting plate 2 is thickness 6mm ~ 10mm steel plate, and has M8 tapped hole 4 at four drift angles of connecting plate; To realize when dismantling, when being difficult to extract foundation ditch tool type guard rail fixing bolt, the bolt of available M8 coordinates with the tapped hole on connecting plate, by rotating M8 bolt, foundation ditch tool type guard rail fixing bolt can be extracted when continuing rotation after M8 bolt and earth surface.
The utility model low cost of manufacture, Environmental Conditions adaptability is good, using scope is wide, convenient and swift, can improve the efficiency that construction fixed by tool type railing, serve positive promoting effect to whole engineering construction, effectively can reduce the cost of production of engineering.
