Beam bottom bonded rebar feed device and using method thereof

Abstract

The invention belongs to the technical field of building engineering construction and provides a beam bottom bonded rebar feed device and a using method thereof. The beam bottom bonded rebar feed device comprises two parts of a rebar feed component and an extension component, the rebar feed component comprises a support frame, a lever device, a rebar fixing device, a clamp support and connecting bolts. The extension component comprises a standard joint and a telescopic joint. According to the design requirement, the beam bottom bonded rebar feed device is used. The beam bottom bonded rebar feed device has the advantages of being simple in structure, capable of being manufactured on a construction site on a large scale, convenient to use and few in operator, so that the construction progress is accelerated; and the beam bottom bonded rebar feed device is simple in construction method and has the effects that the construction efficiency is high, the potential safety hazard is few, and the construction process is safe and controllable.

Description

technical field [0001] The invention belongs to the technical field of building engineering construction, and in particular relates to a beam bottom planting reinforcement feeding device and a using method thereof. Background technique [0002] Reinforced concrete anchoring technology is usually divided into two types, one is pre-embedded anchoring technology, and the other is post-anchoring technology. Chemical planting bars and screws, referred to as planting bars, belong to the latter. The planting bars use chemical adhesive-anchor glue to fix the ribbed steel bars and long screws in the drilled holes of the concrete substrate. A component that acts to anchor the connected parts. [0003] At first, the technology of planting bars was rarely used in the construction of concrete and reinforced concrete. With the full development of old house renovation, the increase of structural reinforcement projects, and the popularization of building decoration, the technology of plant...

AI Technical Summary

Problems solved by technology

Therefore, the planting bar technology is widely used in the anchorage of reinforced steel bars for various building structures such as additions and changes, the anchorage of stressed steel bars such as beams, column heads, floors, and shear walls in structural reinforcement projects, as well as various auxiliary structures, machinery, etc. Screw anchoring during the installation of equipment, pipes, brackets, etc. During the process of planting bars, for some special parts, especially high-altitude positions such as the bottom of the beam and the bottom of the slab, the operating frame must be moved for each bar planting, resulting in low planting efficiency , which increases the labor cost and affects the construction progress at the same time. After searching the existing literature, it is found that the current research on the technology of planting bars in the engineering field is mostly focused on the pull-out test and the study of the mechanism of force, while the construction of bar planting at high places In terms of methods, there is still no good solution
