Embodiment
[0060] figure 1 It is a structural schematic diagram of the prestressed anchor rod 100 in the embodiment of the present invention; figure 2 yes figure 1 Schematic diagram of the state of use.
[0061] Please refer to figure 1 , figure 2 , The prestressed anchor 100 in this embodiment includes an anchor body 5 , an anchor tray 4 , a carrying tray 2 , a damping pad 3 , and an anchor nut 1 .
[0062] One end of the anchor rod body 5 is set as the anchor segment 6 for anchoring and connecting the supported body, and the other end is the outer end exposed outside the supported body during use, and passes through the anchor rod tray 4 and the damping pad 3 in sequence 1. Carrying tray 2, and threaded anchor nut 1 at the outermost end, so that the outer end of the anchor rod body 5 passes through the carrying tray 2 to press the damping pad 3 and the anchor tray 4 against the supported body.
[0063] In one implementation of this embodiment, the anchor tray 4, the carrying tra...

The invention relates to the field of civil engineering supporting structures, aims at solving the problems that existing anchoring supporting structures cannot absorb dynamic loads and energy well and supported bodies are protected insufficiently, and provides a pre-stressed anchor rod. The pre-stressed anchor rod comprises an anchor rod body, a bearing tray and a damping pad. One end of the anchor rod body is an anchoring end, and the other end of the anchor rod body can press the damping pad to a supported body through the bearing tray. The damping pad comprises a shell, the shell is made of a flexible material, and an inner chamber and an outer chamber are defined by the shell. The outer chamber and the inner chamber are isolated through an annular wall. The inner chamber is filled with particle materials. Clearances of the particle materials in the outer chamber and the inner chamber are full of viscous fluid. Flow guide holes communicating with the inner chamber and the outer chamber are formed in the annular wall, and the flow guide holes allow the viscous fluid to pass in two directions but block the particle materials. Elastic resilience parts are further arranged in the inner chamber. The pre-stressed anchor rod has the advantages that the structure is simple, the cost is low, self stability is good, and dynamic load energy can be absorbed well.
Description
technical field [0001] The invention relates to the field of building support structures, in particular to prestressed anchor rods. Background technique [0002] Bolt support is one of the main means of support for supported bodies such as rock and soil at present. It has the characteristics of convenient construction, good effect, and time-saving and labor-saving. It is widely used in underground engineering support, slope engineering, and foundation pit engineering. use. [0003] Most of the support structures in the prior art can only simply drag the supported body, but cannot well absorb the load and energy that may cause damage to the supported body, and the protection of the supported body is insufficient. Contents of the invention [0004] The present invention aims to provide a prestressed anchor rod to solve the problem that the support structure in the prior art can only simply drag the supported body, but cannot well absorb the load and energy that may cause th...
