Problems solved by technology
[0003] Traditionally, the anchor rods installed under the large slab foundation are generally rigid anchor rods, but in fact most of them are steel bars. Since this kind of anchor rods (reinforced bars) are anchor rods of small deformation materials, there cannot be larger anchor rods in the project. The amount of elongation, especially for the case where the transmission tower is built on the ground in the subsidence area, when uneven settlement occurs on the ground, the anchor cannot provide a constant pulling force, which will inevitably cause the sudden break of the anchor, and then cause the foundation of the transmission tower to collapse. damage, affecting the safe and normal operation of transmission lines
[0004] In this regard, in the prior art, there are some bolts that can provide constant tension and large tensile force used in coal mines. However, this type of bolt is mainly used in coal mines, and the tensile properties of bolts are mainly used in coal mines. The pressure-bearing capacity of anchors is very weak, so this type of anchors cannot be adjusted in terms of tension and compression according to the settlement of the ground, so it cannot adapt to the uneven settlement of the ground in the subsidence area

Embodiment Construction
[0034] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0035] In the present invention, in the case of no contrary description, the used orientation words such as "up, down, left and right" usually refer to the up, down, left and right shown in the accompanying drawings; "inside and outside" Refers to the inside and outside of the outline of each part itself.
[0036] According to one aspect of the present invention, the present invention provides a kind of bolt, such as figure 1 As shown, the anchor rod 10 includes a rod body 11, a first hollow sleeve 12 and a pressure-resistant device 13 capable of preventing the rod body 11 from moving to provide pressure resistance, wherein the first end of the rod body 11 is s...

The invention relates to a tool for preventing fixed buildings from being damaged, and discloses an anchor rod and a supporting device for a fixed building. The anchor rod (10) comprises a rod body (11), a first hollow sleeve (12), and a pressure resisting device (13) which can prevent the rod body (11) from moving in order to provide the pressure resistance; the first end of the rod body (11) is glidingly connected with the first hollow sleeve (12); the second end of the rod body (11) extends out from the first hollow sleeve (12). With the adoption of the anchor rod, large pressure can be resisted while large stretching capacity is provided, and therefore, the fixed building can be prevented from unbalancing and damage due to the settlement of the ground; in addition, the performance of the anchor rod under repeated pressing and pulling can be avoided being influenced.
Description
technical field [0001] The invention relates to a tool for preventing damage to a fixed building, in particular to an anchor rod and a supporting device for fixing a building. Background technique [0002] Anchor rods are often set under fixed buildings to support fixed buildings. For example, in order to ensure the safe operation of transmission lines erected on transmission towers, anchor rods are usually set under transmission towers, especially for transmission towers built in subsidence When the ground in the area (caused by coal mining), the biggest hazard of the transmission tower lies in its settlement with the ground (overall settlement and uneven settlement), so it is particularly important to install anchors under the transmission tower at this time. , a large slab foundation (for example, a concrete slab) can be set under the tower foundation of the transmission tower first, and the four foundations at the bottom of the tower foundation can be fixed with the larg...
