Description

Technical Field

[0001] This utility model relates to the field of construction of pre-reserved holes for the rear suspension rods of a hanging basket, and in particular to a vertical pre-reserved device for the installation holes of the rear suspension rods of a hanging basket. Background Technology

[0002] In cantilever bridge construction, the formwork is a crucial piece of equipment, bearing the load of concrete and materials, and ensuring its stability and safety during construction. The accuracy of the pre-drilled holes for the rear hanger rods, a vital component of the formwork, directly impacts the installation effect and overall stability of the formwork. Therefore, developing a device capable of precisely pre-drilling these holes is of paramount importance.

[0003] Traditional methods for pre-drilling installation holes for the rear hangers of the hanging basket often suffer from problems such as inaccurate hole placement and non-compliant hole shapes. These issues can lead to difficulties in installing the rear hangers and even affect the stability and safety of the entire hanging basket. Furthermore, traditional methods are prone to hole flattening and grout leakage causing blockages, further increasing construction difficulty and costs.

[0004] In view of this, and in response to a series of problems existing in the construction of the installation holes for the rear hanger rods of the hanging basket, there is an urgent need to invent a simple and effective vertical pre-reservation device for the installation holes of the rear hanger rods of the hanging basket, to simplify the construction process, reduce manual operation, thereby improving construction efficiency, ensuring project quality and reducing construction costs.

[0023] like Figures 1-4 The present invention provides a vertical pre-reservation device for the mounting hole of the rear hanging rod of the basket, including a pre-reserved hole 1 for the basket, an upper reinforcing plate 8 at the top of the pre-reserved hole 1, a central embedded sleeve 2 along the circumference in the middle, an upper verticality fine adjustment rod 9 and an upper verticality detector 7 along the circumference of the upper reinforcing plate 8 at the upper part of the pre-reserved hole 1, a central verticality detector 5 in the middle of the pre-reserved hole 1, a lower reinforcing plate 4 at the bottom, and a bottom inclined sleeve 3 and a lower verticality detector 10 along the circumference of the lower reinforcing plate 4.

[0024] Specifically, the angle of the top of the pre-drilled hole 1 is adjusted in all directions by using the upper verticality fine-tuning rod 9 set circumferentially at the upper part of the pre-drilled hole 1. During the adjustment process, the upper verticality detector 7, the middle verticality detector 5 and the lower verticality detector 10 are used for real-time observation to ensure the verticality of the pre-drilled hole 1.
