Abstract
The utility model relates to the technical field of an electric power rod, a communication rod, a lamp rod, a pipe pile, and the like, and especially relates to a hollow concrete rod with a concrete flange. The hollow concrete rod with the concrete flange is characterized by comprising the hollow concrete rod which has an end flange and is composed of a reinforcing rib framework and a concrete mortar protective layer poured onto the reinforcing rib framework, wherein the end flange is outward protruded along the radial direction of a hollow concrete rod body; the thickness of a hollow cake which exceeds the outer diameter of the hollow concrete rod body is 2-6 times of the wall thickness of the hollow concrete rod body; and bolt holes are uniformly arranged on the end flange, so that a concrete rod flange is formed. The hollow concrete rod with the concrete flange has the advantages: such a structure is adopted, the concrete flange is formed by the end flange and the bolt holes are uniformly arranged on the concrete flange, so that upper and lower sections of the hollow concrete rod can be conveniently connected and the hollow concrete rod also can be conveniently connected with a base; the hollow concrete rod with the concrete flange has a simple structure, strong bearing capacity and convenience in mounting; the cost is low; and the service life is long.
Description
Technical field
The utility model relates to the technical fields, particularly a kind of hollow concrete bar with the concrete flange such as electric power bar, communication rod, lamp stand, pile tube.
Background technology
The hollow concrete bar is used widely in a plurality of fields such as electric power, communication, illumination, pile foundations, when tradition hollow concrete bar is connected in the upper-lower section connection or with the basis, all be to adopt metal flange to be bolted or to adopt the metal cuff to be welded to connect, this not only makes the cost of hollow concrete bar increase, but also easily corrosion produces potential safety hazard.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of simple in structure, and bearing capacity is strong, the convenient installation, and cost is low, the hollow concrete bar with the concrete flange of long service life.
The purpose of this utility model realizes by following technical proposals:
Hollow concrete bar with the concrete flange of the present utility model; have end flange by cage of reinforcement and be poured in the hollow concrete bar that the cement mortar protective course on this cage of reinforcement forms; described end flange is radially outward outstanding along the hollow concrete club shaft; and the open circles cheese that surpasses this hollow concrete club shaft external diameter; its thickness is 2～6 times of hollow concrete club shaft wall thickness; and on end flange, evenly have bolt hole, form the concrete frame flange.
Bolt hole inner surface built-in metal sleeve pipe in described end flange.
Bolt hole and nut contact surface place built-in metal pad in described end flange.
Outside the bolt hole of described end flange, be arranged with the ring like steel wire net.
Described end flange and hollow concrete club shaft external surface junction are arc surface or chamfered transition.
The end of described hollow concrete club shaft is that an end arranges end flange or two ends all arrange end flange.
Described hollow concrete club shaft is taper hollow concrete club shaft or cylindricality hollow concrete club shaft.
The utility model has the advantages that: owing to having adopted said structure, its hollow concrete bar and end flange adopt cage of reinforcement and concrete directly to build shaping, its end flange has formed the concrete flange, and on the concrete flange, evenly be provided with and have bolt hole, not only made things convenient for the connection of hollow concrete bar upper-lower section, also made things convenient for simultaneously and basic the connection; In addition since the bolt hole inner surface built-in metal sleeve pipe of end flange, with nut contact surface place built-in metal pad and bolt hole outside be arranged with the ring like steel wire net, not only improved bearing capacity, and so that the concrete strength of flange that forms is high, corrosion resistance good.In addition, because end flange thickness of the present utility model is 2～6 times of body of rod wall thickness, guaranteed the concrete strength of flange that end flange forms.
The utility model is simple in structure, and bearing capacity is strong, the convenient installation, and cost is low, long service life.

The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.
As shown in Figure 1 and Figure 2; hollow concrete bar with the concrete flange of the present utility model; it is characterized in that having end flange 4 by cage of reinforcement 3 and be poured in the hollow concrete bar that the cement mortar protective course 2 on this cage of reinforcement 3 forms; described end flange 4 is radially outward outstanding along hollow concrete club shaft 1; and the open circles cheese that surpasses this hollow concrete club shaft 1 external diameter; its thickness is 2～6 times of hollow concrete club shaft 1 wall thickness; and on end flange 4, evenly have bolt hole 5, form the concrete frame flange.
Described end flange 4 is arc surface or chamfered transition with hollow concrete club shaft 1 external surface junction.Because the utility model hollow concrete bar and end flange 4 adopt cage of reinforcement and concrete directly to build shaping, and end flange thickness is 2～6 times of hollow concrete club shaft wall thickness, the concrete frame strength of flange of having guaranteed end flange formation is high, has satisfied the requirement that electric power bar, communication rod or lamp stand are connected or are connected with pipe pile foundation with hypomere.
Such as Fig. 4, shown in Figure 5, the hollow concrete bar with the concrete flange of the present utility model, except pressing concrete force request arrangement of reinforcement, can also be at the bolt hole 5 inner surface built-in metal sleeve pipes 7 of described end flange 4, to increase bearing capacity.
As shown in Figure 6, the utility model can increase bearing capacity equally at the bolt hole 5 and nut contact surface place built-in metal pad 6 of described end flange 4.
In order to increase the impact resistance of end flange 4, the utility model is arranged with ring like steel wire net 8 outside the bolt hole 5 of described end flange 4, as shown in Figure 7.
As shown in Figure 1 and Figure 2, the end of hollow concrete club shaft 1 described in the utility model is that an end arranges end flange, this structure makes things convenient for pile foundation to connect, also can end flange all be set two ends, this structure not only is convenient to pile foundation and is connected, and also is convenient to simultaneously the connection of hollow concrete bar upper-lower section.The utility model is applicable to the requirement of the different hollow concrete bars such as electric power bar, communication rod, lamp stand or pipe pile foundation.
