Fracture and slip preventing safety device for deep foundation pit supporting beam

Abstract

The invention relates to a fracture and slip preventing safety device for a deep foundation pit supporting beam. The fracture and slip preventing safety device comprises the supporting beam, lantern rings and connecting ropes. The multiple lantern rings are arranged in the length direction of the supporting beam, and the outer portion of the supporting beam is sleeved with the lantern rings. Each lantern ring is provided with a plurality of through holes symmetric left and right. The number of the through holes formed in one lantern ring is the same as the number of the through holes formed in another lantern ring, and the through holes formed in one lantern ring coaxially correspond to the through holes formed in another lantern ring in a one-to-one manner. The two ends of each connecting rope penetrate the same set of corresponding through holes, and then are fixed to an embedded anchoring device constructed on a crown beam. The fracture and slip preventing safety device has the beneficial effects that the situation that after the supporting beam fractures and slips into a deep foundation pit, consequently the balance of a supporting system of the deep foundation pit is affected is prevented, and the safety of construction work in the deep foundation pit is guaranteed; the structure is simple and reliable, and the service life is guaranteed; hoisting of the supporting beam is stable, and the supporting beam can be prevented from rolling; and the connecting ropes freely slide in the through holes, and the supporting beam smoothly slides to the middle portions of the connecting ropes through the dead load so that the stable hoisting state of the supporting beam can be guaranteed.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a safety device for preventing breakage and slipping of support beams in deep foundation pits. Background technique [0002] Nowadays, the construction of deep foundation pits has been carried out in many places in China, and safety accidents during the construction of deep foundation pits often occur, causing great negative impacts. The control technology in the process of deep foundation pit construction lies in the improvement of the support system, which is the key to ensure the overall stability of the foundation pit. The invention mainly solves the anti-breakage and slippage of the support beams after erection during the construction of deep foundation pits, and prevents safety accidents of deep foundation pits caused by falling from high places or instability of deep foundation pits caused by the falling of the support beams. [0003] The construction of deep foundati...

Problems solved by technology

At present, after the erection of steel supports in many deep foundation pits, the protection of the steel supports rarely plays a role, and the main method is to use wire ropes to suspend them at the ends.
