Benefits of technology

The purpose of this new type of tool for removing castings from buildings was developed by researchers at MIT Laboratories (Massachusetts). It allows for repeated usage over time without requiring expensive equipment that requires maintenance. Additionally, its flexibility makes it suitable for various types of materials like punchouts, bolts, etc., making it ideal for applications such as building foundations. Overall, these tools have improved efficiency and reduced manufacture costs compared to traditional methods.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the efficiency and economics of producing and installing new types of reinforce consistently without requiring unnecessary steps during assembly. Previous methods have resulted in wasted time and increased costs due to excessive labor required at different stages of the project's life cycle. Therefore, these previous solutions were limited because they did not provide flexibility with respectable design options.

Embodiment 1

[0040] Based on the defects of the above prior art, see Figure 1-9 : This embodiment provides a precast concrete beam without pre-embedded multi-functional spreader, relates to precast concrete beam 4, including a detachable spreader assembly 1, the detachable spreader assembly 1 is provided with a lifting ring 11, the The detachable hanger assembly 1 includes a balance bar 12 and a stirrup clip 14 sleeved and fixedly installed on the balance bar 12. The stirrup clip 14 is provided with the stirrup on the precast concrete beam 4. Matching laps 141 .

[0041] The detachable hanger assembly of this embodiment is fixed on the closed hoop or open hoop of the precast concrete beam through the overlapping part of the stirrup clip, so as to grasp the precast concrete beam; the precast concrete beam of this embodiment does not need conventional prefabricated concrete Buried spreader.

[0042] This example proposes to replace the pre-embedded spreader with a multi-functional spreader f

Abstract

The invention provides a pre-embedded-free multi-functional lifting appliance for a precast concrete beam, and relates to a precast concrete beam. The pre-embedded-free multi-functional lifting appliance for the precast concrete beam comprises a detachable lifting appliance assembly, wherein a lifting ring is arranged on the detachable lifting appliance assembly; the detachable lifting appliance assembly comprises a balance rod and a stirrup clamping piece fixedly arranged on the balance rod in a sleeving mode; and a lap joint part matched with a stirrup on the precast concrete beam is arranged on the stirrup clamping piece. According to the pre-embedded-free multi-functional lifting appliance for the precast concrete beam provided by the invention, the multi-functional lifting appliance is used for replacing an embedded lifting appliance for the precast reinforced concrete beam, so that under the condition that the structural performance of a precast beam unit is not affected, a lifting jig which can be repeatedly used and adjusted and is suitable for various types of precast beams is used for grabbing the stirrup of the precast beam to lift, the manufacturing and construction procedures of the precast reinforced concrete beam are reduced, and the production and manufacturing cost of the precast reinforced concrete beam is reduced.
