Assembled concrete component reinforcement magnetic suspension connecting and positioning device

Abstract

The invention provides an assembled concrete component reinforcement magnetic suspension connecting and positioning device which is used for positioning an upper concrete component and a lower concrete component, so that upper and lower reinforcements to be connected are in coaxial butt joint. The device comprises a control mechanism, at least two groups of support mechanisms, a positioning mechanism and a support mechanism, the supporting mechanism comprises a lower support and an upper support, the upper support comprises a support plate and a limit plate, both the support plate and the lower support are electromagnets, like magnetic poles of the support plate and the lower support are oppositely placed, the positioning mechanism comprises a first mark and a second mark which are arranged at corresponding positions of assembly surfaces of the upper concrete component and the lower concrete component, the lower support is placed at the first mark, the upper support is placed at the second mark, coils in the support plate and the lower support are serially connected onto the same circuit, the support mechanisms can be the same in magnetic force, support stability is ensured, and the control mechanism is used for controlling the magnetic force of the electromagnets. By the aid of the principle of magnetic suspension, the reinforcements of the upper concrete component and the lower concrete component are rapidly and accurately centered.

Description

technical field [0001] The invention belongs to the field of prefabricated buildings, in particular to a magnetic levitation prefabricated concrete member reinforcement connection positioning device. Background technique [0002] The biggest feature of prefabricated buildings is green construction, energy saving and environmental protection. The prefabricated concrete components used are assembled and connected at the construction site, which can avoid or reduce the impact of construction on the surrounding environment. The high degree of mechanization can greatly shorten the construction period and reduce construction costs. On-site labor resource input. From the perspective of the global environment, it is imperative for the construction industry to develop into a prefabricated construction method. [0003] The prefabricated concrete structure refers to the concrete structure assembled by prefabricated concrete components through reliable connection, and then the prefabri...

Problems solved by technology

The core and difficult point of the connection of prefabricated concrete members is the quality of the connection of the steel bars in the upper and lower concrete members. The existing technology and process are difficult to ensure that the non-grouting connecting steel bars and the grouting connecting steel bars are coaxially connected in the grouting sleeve.

According to statistics, in actual engineering, the accurate centering connection rate between the sleeve and the grouted connecting steel bar is about 20%. The main reasons are as follows: 1) It is difficult to insert the grouted connecting steel bar at the end of the same component into the corresponding sleeve, which makes the installation of the component difficult ;2) When the steel bar of the grouting connection section is inserted into the grouting sleeve, it is close to the inner wall of the sleeve. During subsequent grouting, the grout cannot completely wrap the steel bar of the grouting connection section, so that the connection strength of the sleeve is greatly reduced, and the connection part of the component is seriously weakened. load transfer
