Problems solved by technology

[0002] With the progress of society and the needs of engineering construction, the application of prestressing technology is increasing, and the prestressing construction technology and equipment are also diverse. For the prestressing construction technology of anchor cables, most of the existing limiting plates are concave Groove ladder, such as figure 1 , this kind of limiting plate is divided into two steps. When the prestress is stretched, the clip is pulled apart by the distance of the step gap. When it is released, the clip will shrink back by the step gap or more, resulting in prestress loss.

Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] like figure 1 As shown, the prestressed tension limiting plate of the embodiment of the present invention adopts a kind of prestressed tension limiting plate. Before the prestressed tensioning of the anchor cable is completed and released, the movable top plate is pushed by the elastic force of the internal spring to make the The anchor clips are clamped to prevent the loss of prestress caused by the retraction of the clips during release, and to make the prestress tension meet the design requirements without over-tensioning.

[0019] The prestressed tension limiting plate is mainly compose...

Abstract

The invention discloses a prestressed tension limiting plate. The prestressed tension limiting plate is disposed between an anchorage device and a jack and comprises a limiting plate body, a detachable spring, a movable top plate and a buckle ring which are arranged inside the limiting plate body. The shape of the limiting plate body is a hollow cylinder with one end open, the top end of the limiting plate body is an open end, the open end is in contact with the anchorage device, and the bottom end of the limiting plate body is in contact with the jack. A step groove is formed in the open endof the limiting plate body, an annular limiting groove is formed in the lower portion of the step groove, and the buckle ring is disposed in the limiting groove. One end of the spring is in contact connection to the bottom end of the limiting plate body, and the other end of the spring is in contact connection with the movable top plate. The movable top plate moves up and down on the inner wall ofthe limiting plate body and is limited by the buckle ring at the top end. A plurality of circular holes are formed in the limiting plate body and the movable top plate. The prestressed tension limiting plate can reduce the loss of the tension prestress, reduce the damage to an anchor cable, and save the cost.

Description

technical field [0001] The invention relates to the technical field of anchorage construction, in particular to a prestressed tension limiting plate. Background technique [0002] With the progress of society and the needs of engineering construction, the application of prestressing technology is increasing, and the prestressing construction technology and equipment are also diverse. For the prestressing construction technology of anchor cables, most of the existing limiting plates are concave Groove stepped, such as figure 1 , This kind of limiting plate is divided into two steps. When the prestress is stretched, the clip is pulled apart by the distance of the step gap. When it is released, the clip will shrink back by the step gap or more, resulting in the loss of prestress. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a prestressed tension limiting plate aiming at the defects in the prior art. [0004] Th...
