A safety device is provided. The safety device (100) is for securing an individual to a concrete element (2) of a structure during construction work. The concrete element (2) is of the type comprising a concrete body (4) having one or more lifting pins (6) embedded in respective lifting pin holes (8) in said body. The safety device in the orientation intended during use comprises: -an anchoring element (10); and a top element (12); wherein said anchoring element (10) comprises engagement means (14) configured to releasably engage with the head of a lifting pin of the type comprising a longitudinal stem (18) and a head (20) arranged at an upper end of said stem, said head (20) of said lifting pin (6) is having a larger extension, compared to said stem, in a transversal direction Y; so as to enable said anchoring element (10) and said lifting pin (6) to shift configuration between an engaged configuration with each other and a disengaged configuration and vice versa; wherein said anchoring element (10) comprises a first fastening means (22) configured to be connected to said top element (12); wherein said top element (12) comprises a second fastening means (24) configured to be connected to said anchoring element (10); wherein said safety device comprises fixation means (26) for fixing a safety line thereto.

A connector assembly, which in one embodiment has an upper connector and in another embodiment has a lower connector. The assembly can have a gusset plate sandwiched between the upper and lower connectors. Also, disclosed is a hoistable connector assembly, a lifting frame assembly, a coupling system for modular frame units, a method for assembling a module unit using the connector assembly, and a modular frame unit and building having the connector assembly. Also, a system for coupling adjacent modular frame units for forming a modular building and a method for coupling modular frame units for forming a modular building are provided.

Systems, methods, devices, and other techniques for a dynamic fabrication system. In some implementations, a computing system obtains a digital model of a physical structure. A fabrication plan for the physical structure is generated. The fabrication plan is provided to a fabrication system to execute the automated fabrication procedure according to the fabrication plan. A set of operations are performed for each of at least a subset of tasks from a set of tasks executed by the fabrication system during an automated fabrication procedure to identify an adjusted fabrication plan. The fabrication system is directed to continue execution of the automated fabrication procedure according to the adjusted fabrication plan.

A stripping lifting insert is provided for precast insulated panels having an insulating material layer between opposing wythes, the insulating material layer, wythes, and precast insulated panel having respective widths. The stripping lifting insert includes an elongated connecting shaft having a shaft axis. First and second spaced apart wythe engagement members are connected to the connecting shaft in spaced apart relation to each other. Each wythe engagement member includes a hub and a plurality of three or more protrusions connected to and emanating from hub. Each of the protrusions extending radially outward from the shaft axis. The wythe engagement members have a height less than the width of the wythes, whereby each wythe engagement member can be completely embedded in a respective wythe of the precast insulated panel. A precast insulated panel and a method of making a precast insulated panel are also disclosed.

An installation device used in an elevator shaft has a first carrier with first and second carrier ends, a support element pivotably arranged on the first carrier end, and a holding apparatus holding a displacement apparatus by which installation material can be displaced in the elevator shaft. When the installation device is in an installation position, the first carrier end is supported against a threshold of an elevator shaft door opening by the support element and the second carrier end is supported at least indirectly against a shaft wall that is opposite the door opening. The holding apparatus is arranged on an upper side of the installation device in the installation position such that the displacement apparatus is supported from above on the holding apparatus.

Provided is a shelter floating device which enables an amphibious shelter to stably float on a surface of waters. The shelter floating device is provided on a lower surface of the amphibious shelter, and has a protruding floater, a Scott Russell mechanism unit, and a jack (operating means). The protruding floater is connected to the jack through the Scott Russell mechanism unit, while at the same time, being supported by a support device. The jack is fixed to the lower surface of the amphibious shelter. Consequently, by operating the jack, the protruding floater projects itself to an outside of side surfaces of the amphibious shelter along a perpendicular direction.

A tower section and a wind generating set. The tower section comprises a tower section body and hoisting lugs, wherein through holes are provided in the sidewall of the tower section body, and an inner cavity of the tower section is communicated with the outside by means of the through holes; the hoisting lugs are provided in the through holes, are movable along central lines of the through holes, and can move between a first position where the hoisting lugs extend out of the tower section body and a second position where the hoisting lugs are retracted to the tower section body, so as to hoist the tower section. Because the hoisting lugs can selectively extend out, a tower hoist is not needed to be connected to a flange in a tower section hoisting process, and the hoist is mounted on the hoisting lugs.
