Embodiment 1

[0039] Such as figure 1 and figure 2 , Figure 4 and Figure 5 As shown, the anchor built-in locking structure provided in this embodiment is used in conjunction with the shaped steel waist beam, and the shaped steel waist beam includes an upper steel beam 10 and a lower steel beam 11 that are oppositely arranged. The built-in locking structure of the anchor includes the anchor rod and the mounting frame assembly; the mounting frame assembly is embedded in the space formed by the upper steel beam 10 and the lower steel beam 11, and the top surface 201 of the mounting frame assembly located in the space is connected to the upper steel beam 10, The bottom end surface 202 is connected to the lower steel beam 11; one end of the anchor rod is fixed in the anchor hole 60 on the rock and soil layer, and the other end of the anchor rod is passed through the mounting frame assembly and is fastened to the mounting frame assembly.

[0040]Specifically, a space extending along the len...

Embodiment 2

[0066] Such as Figure 3-Figure 5 As shown, this embodiment also provides a built-in locking structure for the anchor rod, which differs from the built-in locking structure for the anchor rod in the embodiment in that the mounting bracket assembly includes a mounting bracket body 20 as described below; the mounting bracket body 20 has a first installation The anchor rod passes through the first installation hole and is firmly connected with the installation frame body 20 .

[0067] Specifically, at this time, the thickness of the backing plate portion 203 is increased, and the side of the backing plate portion 203 close to the support pile 40 and the side surface away from the support pile 40 are all set as inclined surfaces, and then replaced by the backing plate portion 203 with increased thickness. The anchor 21 , the wedge plate and the backing plate part 203 jointly support the anchor rod, and then the force of the anchor rod is tensioned and locked on the upper steel bea...

Abstract

The invention provides an anchor rod built-in locking structure, and relates to the technical field of rock-soil engineering supporting. The anchor rod built-in locking structure is matched with a profile steel waist rail to be used, and located between an upper steel beam and a lower steel beam; the upper steel beam and the lower steel beam are arranged oppositely, and the anchor rod built-in locking structure includes an anchor rod and an installation frame assembly; the installation frame assembly is embedded in the space formed by the upper steel beam and the lower steel beam, the top endface, located in the space, of the installation frame assembly is connected with the upper steel beam, and the bottom end face of the installation frame assembly is connected with the lower steel beam; and one end of the anchor rod is fixedly arranged in an anchor hole of a rock-soil layer, and the other end of the anchor rod is arranged in the installation frame assembly in a penetrating mode andconnected with the installation frame assembly in a fastening mode. According to the anchor rod built-in locking structure, the technical problems that the occupied space of an anchor rod supportingstructure in the prior art is large, the integrality of existing embedded profile steel waist rails is low, and the installation is not convenient are solved.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering support, in particular to a built-in locking structure of a bolt. Background technique [0002] With the continuous development of urban construction, a large amount of underground space is compressed, and the space available for foundation pit engineering support is getting smaller and smaller. In the traditional installation method, two sets of steel beams arranged at intervals up and down are located between the backing plate and the support pile, and the backing plate is fixed on the side of the steel beam away from the support pile, and one end of the anchor rod extends into the side of the support pile. The other end of the anchor rod passes through the backing plate and is fixed by the anchor. However, when the distance between the support pile and the main structure is relatively close, since the end of the anchor rod away from the support pile exceeds the backing plate a...
