Abstract

An armored concrete electrical pole is composed of main bars, short bars, spiral bars, inner steel hoops, drift bolt pipes and a joint steel ring, wherein the main bars and the spiral bars are made into a steel bar framework which is then arranged in an electrical pole steel mold, is poured with concrete, is processed by a centrifuge, and is made into an armored concrete electrical pole, wherein the drift bolt pipes are transversely installed in the electrical pole according to a certain distance and place, the short bars on the drift bolt pipes are welded with the main bars, and the inner steel hoops are installed under the drift bolt pipes in a binding mode, and the joint steel ring is installed on the bottom of the electricity pole. The utility model has the beneficial effects that the structure is reasonable, HRB400 rolled steel is used for producing the electrical pole, which has few differences with the existing technique, and does not need other investment cost, when the HRB400 rolled steel is used to replace a ton of Q235 rolled steel, the cost is saved about that the HRB400 rolled steel which has the same strength with the Q235 rolled steel costs 0.604T*5300yuan/T=3201.2 yuan, and the Q235 rolled steel costs 1T*5350yuan/T=5350 yuan, namely the cost is saved about (5350-3200)/5350*100% is approximately equal to 40%, namely about forty percent of the cost is saved, thereby about four hundred thousand yuan is saved when the rolled steel with Q235 strength which costs a million yuan is replaced.

Description

A kind of reinforced concrete pole

Technical field

The utility model relates to a kind of reinforced concrete pole, belongs to electric pole structure field.

Background technology

In order to carry out the techno-economic policy of country, accomplish advanced technology, safe and applicable, economical rationality, guarantee quality, honor is according to the requirement of " Code for design of concrete structures " GB50010-2002 national standard, and China's structural safety is lower than world level generally, but material usage is also many, and its reason is that higher in the world degree of safety is to realize by the material of higher-strength.

Summary of the invention

In order to overcome the deficiency of prior art structure, the utility model provides a kind of reinforced concrete pole.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of reinforced concrete pole, comprise main muscle, short muscle, spiral bar, interior stirrup, drift bolt pipe, joint steel ring, main muscle, spiral bar are made into cage of reinforcement, put into steel mould for electric pole, concrete in the cast, centrifugal by centrifuge, make reinforced concrete pole, the drift bolt pipe laterally is contained in the electric pole according to the certain distance position, short muscle on the drift bolt pipe and the welding of main muscle, interior stirrup is equipped with in colligation under the drift bolt pipe, and the joint steel ring is contained in the electric pole bottom.

A kind of reinforced concrete pole is replaced by the HRB-400 new type steel with the main muscle Q235 steel in the existing electric installation national standard SD141-3 atlas.

Benefit of the present utility model is rational in infrastructure, produce electric pole with the HRB400 steel and on technology, do not need other investment cost, reduce expenses with 1 ton of Q235 steel of the every replacement of HRB400: the steel expense 0.604T of equality strength HRB400 * 5300 yuan/T=3201.2 unit, the steel of Q235 take 1T * 5350 yuan/T=5350 unit, and (5350-3200) ÷ 5350 * 100% ≈ 40% that promptly reduce expenses promptly reduce expenses and about 40% that is to say that the steel of the Q235 intensity of 1,000,000 yuan of replacement can reduce expenses about 400,000 yuan.

Description of drawings

Below in conjunction with drawings and Examples utility model is further specified.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model A-A schematic cross-section.

The specific embodiment

Embodiment 1: as shown in Figure 1, 2, a kind of reinforced concrete pole is with main muscle 1, short muscle 2, spiral bar 3, interior stirrup 4, drift bolt pipe 5, joint steel ring 6, main muscle 1, spiral bar 3 are made into cage of reinforcement, put into steel mould for electric pole, concrete in the cast, centrifugal by centrifuge, drift bolt pipe 5 laterally is contained in the electric pole according to the certain distance position, short muscle 2 on the drift bolt pipe 5 and main muscle 1 welding, interior stirrup 4 is equipped with in 5 times colligations of drift bolt pipe, and joint steel ring 6 is contained in the electric pole bottom.Make reinforced concrete pole, the main muscle Q235 steel in the steel concrete are replaced by the HRB400 new type steel.

Claims

1. reinforced concrete pole, it is characterized in that comprising main muscle, short muscle, spiral bar, interior stirrup, drift bolt pipe, joint steel ring, main muscle, spiral bar are made into cage of reinforcement, put into steel mould for electric pole, concrete in the cast, centrifugal by centrifuge, make reinforced concrete pole, the drift bolt pipe laterally is contained in the electric pole according to the certain distance position, short muscle on the drift bolt pipe and the welding of main muscle, interior stirrup is equipped with in colligation under the drift bolt pipe, and the joint steel ring is contained in the electric pole bottom.
