Description

Technical Field

[0001] This utility model relates to the field of anchors, and in particular to concentric circle anchors for foundation pit engineering piles. Background Technology

[0002] A bow-string beam support mechanism is a support structure that uses steel strands, compression rods, and bearing rods to provide support for the waler of a foundation pit. Anchors are used to fix the ends of the steel strands. Current anchors for large-span foundation pits often have a wide, protruding block at the bottom. In the first layer of support, two-section steel walers are often used, and the support force transmitted from the corner braces is entirely resisted by pre-embedded bolts, failing to form a reliable shear resistance and posing a safety hazard. In the construction of cement-soil mixing piles with inserted steel sections, the spacing of the steel sections is fixed, and the steel sections often conflict with the protruding block at the bottom of the anchors, making construction impossible.

[0024] Combined with appendix Figure 1 and attached Figure 2 As shown, a concentric circle anchor for foundation pit engineering piles includes a foundation frame 1, a trapezoidal frame 2, a protruding block 3, an arc plate 4, and a guide tube 5. Several arc plates 4 arranged vertically are fixed inside the foundation frame 1. A guide tube 5 is provided between two adjacent arc plates 4. A protruding block 3 is fixed at the bottom of the foundation frame 1. A trapezoidal frame 2 is fixed at the notch of the foundation frame 1. A right-angled groove 6 for fitting the end of the bearing rod is provided at the front end of the foundation frame 1.

[0025] The anchor has a right-angled tip at the top and a right-angled groove 6 at the front end that fits and fixes to the end of the bearing rod, thus securing two anchors to both ends of the bearing rod. The steel section of the cement-soil mixing pile is inserted between two protrusions 3, making the anchor connection more stable.

[0026] The trapezoidal frame 2 includes a first crossbeam assembly 21 and a second crossbeam assembly 22.

The upper base of the first crossbeam assembly 21 and the lower base of the second crossbeam assembly 22 are fixed together.

[0027] The trapezoidal frame 2 is a right-angled trapezoidal frame that fits perfectly with the notch of the base frame 1, forming the right-angled tip of the anchor.

[0028] Combined with appendix Figure 3 and attached Figure 4 As shown, both the first beam assembly 21 and the second beam assembly 22 are composed of a cover plate 211, a web plate 212, and a diaphragm plate 213. The web plate 212 is fixed between two parallel cover plates 211, and the diaphragm plate 213 is fixed between the cover plate 211 and the web plate 212.
