Abstract

The utility model discloses a prestrssed steel rod and the two ends of the steel rod are welded with support boards. The support boards are then connected with prestressed material to reinforce the structure of large flexibility rods. The prestressed steel rod is lighter than the cement rod or other steel rod of the same size. According to the utility model, the stress distribution and the lateral rigidity of the rod body are improved. The prestressed steel rod has the advantages of light weight, low cost, easy recovery and the like, which effectively replaces the existing transmission steel towers and cement rods and is simultaneously used in traffic signal lamp bars, traffic signs, monitoring rods, lighting rods and flagpoles.

Description

A kind of pre-stressed steel pipe bar

Technical field

The utility model patent relates to the steel pipe pole field, relates in particular to a kind of pre-stressed steel pipe bar.

Background technology

All be transmission of electricity shaped steel tower and cement pole now at present in our the power transmission lines system, this type of steel pipe pole class formation is big flexibility structure, in structure design often intensity have more than needed, and insufficient rigidity.The structure of roadway sign bar and monitoring bar and so on also is like this.Cement pole is to use cement to make, and has produced a large amount of not tractable rubbish after scrapping, and environment contaminates society.And the big open-air transportation of bar weight that cement is made is extremely inconvenient.

The utility model content

Technical problem to be solved in the utility model is exactly at above-mentioned deficiency, and provide a kind of in light weight, save the energy, safe and reliable a kind of pre-stressed steel pipe bar.The both sides of central axis are equipped with some prestressed cables in the body of rod.

The purpose of this utility model can be achieved through the following technical solutions, and the pre-stressed steel pipe bar comprises the body of rod and prestressing apparatus.

The pre-stressed steel pipe bar is characterized in that: inboard, body of rod two ends all is welded with gripper shoe;

The pre-stressed steel pipe bar is characterized in that: two gripper shoes are connected by the prestressed cable material;

The pre-stressed steel pipe bar is characterized in that: there is ground tackle at prestressed cable material two;

Compared with prior art, what the utility model adopted is that steel pole two is welded with gripper shoe, connects gripper shoe to add the structure of powerful flexibility bar class rigidity with the prestressed cable material again.The pre-stressed steel pipe bar is lighter than cement pole and other steel pole weight under identical specification.The pre-stressed steel pipe bar has improved the stress distribution of the body of rod, improved body of rod lateral rigidity, have characteristics such as in light weight, that cost is low, material recovery is easy, existing transmission of electricity shaped steel tower and cement pole be can effectively substitute, traffic signals lamp stand, traffic sign bar, monitoring bar, illumination lamp stand and flagpole etc. can be applicable to simultaneously.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing:

Structure of the present utility model is seen Fig. 1-shown in Figure 8, and a kind of pre-stressed steel pipe bar includes the body of rod, gripper shoe and ground tackle.

The body of rod 1 is polygon taper of metal system or taper shape.Rope material hole on upper backup pad and the lower supporting plate and ground tackle are circle distribution.All be welded with gripper shoe at the body of rod 1 upper and lower side, the inside respectively indentation of gripper shoe has certain distance, gripper shoe is simultaneously also as conventional stiffening plate, the rope material hole 10 that some circumference are arranged on the gripper shoe, prestressed cable material 4 is passed the rope material hole 10 of upper backup pad 2 and band reinforcement gusset lower supporting plate 6, one end will pass prestressed cable material 4 usefulness ground tackles 3 anchorings of gripper shoe, after the other end arrives suitable length to 4 stretch-draw of prestressed cable material with prestress tensioning equipment, also will pass prestressed cable material 4 usefulness ground tackles 3 anchorings of gripper shoe.End flange also can be used as lower supporting plate 6 usefulness.

Gripper shoe has two kinds of structures: 1, be cirque structure, on have the rope material hole 10 of some circumference, the outside that stream zinc hole 5 is arranged.2, be single chip architecture, every gripper shoe is welded in the inwall of the body of rod 1, also is circumference, and every gripper shoe all has a rope material hole 10.

For the facility of processing and transporting, when a cover steel pole can be made up of more piece, then adopt flange to connect or socket connection.

When flange connects, steel pole two ends welded flange, joint 7 flange in the bottom are connected by bolton with the following joint of steel pole 8 top flange on the steel pole.Again prestressed cable material 4 is passed the rope material hole 10 of the gripper shoe of two ends correspondence, one end will pass prestressed cable material 4 usefulness ground tackles 3 anchorings of gripper shoe, after the other end arrives suitable length to 4 stretch-draw of prestressed cable material with prestress tensioning equipment, also will pass prestressed cable material 4 usefulness ground tackles 3 anchorings of gripper shoe.

During socket connection, joint 7 bottoms are bigger slightly than the following joint of steel pole 8 top diameters on the steel pole, the top that joint 7 bottoms cover is received joint 8 under the steel pole on the steel pole, and again by the equipment tension, for guaranteeing the prestressing force effect, the suitable position of joint 7 bottom interior wall is welded with block 9 on steel pole.After each pole body 1 grafting finishes, prestressed cable material 4 is passed the rope material hole 10 of the gripper shoe of two ends correspondence, one end will pass prestressed cable material 4 usefulness ground tackles 3 anchorings of gripper shoe, after the other end arrives suitable length to 4 stretch-draw of prestressed cable material with prestress tensioning equipment, also will pass prestressed cable material 4 usefulness ground tackles 3 anchorings of gripper shoe.

If the body of rod 1 each side force-bearing situation difference, then ground tackle 3 distributing positions on the upper backup pad 2 and prestressed cable material 4 stretch-draw length are made corresponding adjustment according to actual state, ground tackle 3 can be an asymmetric arrangement, and the stretch-draw length of every prestressed cable material 4 is also not necessarily identical.

The rope material hole 10 of lower supporting plate 6 also can be directly on end flange in the utility model, anchor slab 3 and intermediate plate 5 are positioned at the bottom surface of lower supporting plate 6 (end flange), central authorities left a sinking space when steel pipe pole basis was pre-buried, after steel pipe pole was installed on the stone bolt, the tail end of ground tackle 3 and prestressed cable material 4 just in time was positioned at this space.

[0027] though the utility model only illustrate and describe by embodiment; but those skilled in the art should understand; in the scope of claims; different profiles and quantity to gripper shoe; the position of the different size of prestressed cable material 4 and quantity and gripper shoe all belongs to protection domain of the present utility model.
