Embodiment Construction

[0018] Embodiments of the concrete electric pole tension anchoring device of the present invention:

[0019] like Figure 1-5 As shown, the concrete pole tensioning anchorage device of the present invention comprises a tensioning head 3 for fixing steel bars, a tensioning traction device for connecting with a jack and pulling the tensioning head 3 and threadedly assembled on the tensioning head 3 It is used to stop on the steel mold 7 to keep the tension head 3 in a tensioned threaded fastening support. The threaded fastening support is an anchor plate 4, which includes a plate bottom 402 and a boss 401 protruding from the front end of the plate bottom. The center of the bottom 402 is provided with a threaded hole that is threadedly engaged with the tension head 3 .

[0020] In the above embodiment, the bosses 401 are protrusions fixedly connected to the bottom of the pan and evenly distributed along the circumference of the bottom of the pan.

[0021] In the above embodime...

Abstract

The invention relates to a tensioning and anchoring device for concrete poles and belongs to the technical field of electric power transmission. The tensioning and anchoring device comprises a tensioning head used for fixedly connecting with a rebar, a tensioning puller used for connecting a jack and pulling the tensioning head and a threaded fastening support mounted on the tensioning head through a thread and used for stopping on a steel form to retain tensioning state of the tensioning head. The threaded fastening support is an anchoring plate comprising a plate bottom and bosses protruded on the front ends of the plate bottom. The bosses are provided with front end faces for fitting with the steel form in a blocking way. A thread hole is formed in the center of the plate bottom and matched with the thread of the tensioning head. According to the arrangement, the anchoring plate sleeving the tensioning head is rotated so as to be abutted against the steel form in a rapid and fastened manner. Besides, with large stressed area of the anchoring plate, tensioning force is evenly and stably applied to the steel form.

Description

technical field [0001] The invention relates to a tensioning and anchoring device for a concrete electric pole, which belongs to the technical field of electric power transmission. Background technique [0002] With the rapid development of my country's power industry, the requirements for the bearing capacity and durability of concrete poles are getting higher and higher, especially prestressed concrete poles, which are low in price and have a long service life, and are in great demand in the market. However, prestressed concrete poles with greater bearing capacity will also bear greater tension, which puts forward higher requirements for the processing of prestressed concrete poles. During the production and processing of prestressed concrete poles, tensioning is the key process, which directly affects the product quality of the poles. [0003] A conventional tension anchoring device generally includes a tension traction member, a tension head, a fastening support and the...
