An apparatus for use in lifting or pulling an object. The apparatus comprises a female part including a hole extending into the female part. The hole includes a first portion and a second portion, the first portion being narrower than the second portion. The apparatus further comprises a sleeve comprising a plurality of arms, at least one of which is flexible. The plurality of arms define a channel, the arms being configured for insertion into the hole in the female part such that distal portions of the arms are at least partially positioned in the second portion of the hole. The apparatus further comprises a male part, for insertion into the channel of the sleeve, comprising a distal stop.

A collar flange assembly clamping tool is disclosed, including an axle having a long axis, and a pair of arms mounted on the axle. At least one of the arms is slideable along the long axis. Each arm includes a primary axis perpendicular to the long axis of the axle, a proximal end portion, and a distal end portion with a tab. The proximal end portion includes a clamping device that moves in a direction perpendicular to the primary axis of the arm and the long axis of the axle.

A work management system for managing work to be performed on a work subject. The work management system includes multiple work robots, a storage unit, a generator, and an instruction unit. The work robots each include movement means capable of moving to any location. The storage unit stores target information on a target state of the work subject and current state information on a current state of the work subject. The generator generates work procedure information indicating a work procedure to be performed by the work robots so that the work subject is brought close to the target state, on the basis of the target information and the current state information. The work procedure information includes work instruction information for instructing the work robots to perform one or more types of work to be performed on the work subject.

Disclosed herewith a modular integrated building and a construction method thereof. The building comprises multiple prefabricated room units (1). A bottom of a load-bearing structure of the prefabricated room unit (1) is provided with a semi-prefabricated connecting port (2). Reinforcing bars arranged at a top of the prefabricated room unit (1) of a next floor are inserted in the connecting port (2) and thus connected with reinforcing bars arranged therein, so that the prefabricated room units (1) of two adjacent floors are connected with each other through in-situ casting concrete in the connecting port (2). A cast-in-situ concrete interlayer (3) is arranged on a top plate (11) of the prefabricated room unit (1) of a next floor, for connecting adjacent prefabricated room units (1) of a same floor together.

A wall brace system and/or a retainer member thereof that supports a structural member of the wall brace system, as well as a method of forming the retainer member. In particular, the retainer member includes tabs formed from the body of the retainer member. For example, the tabs may be formed from the edges of the retainer body or from within the edges of the retainer body. When installed, the wall brace system with the retainer member provides an apparatus for supporting a wall in a building structure, which has been moved inward by pressure from the earth outside in order to return the wall to a desired position. The wall brace system comprises a structural member, the retainer member, a mounting member, a load member, a jack, and/or a locking member.

A collar flange assembly welding fixture is disclosed, including a stand, a circular mount structure, and a support assembly which are configured to provide access to a front side and a back side of a collar flange assembly held by the support assembly. The stand has a plurality of circumferential bearings equidistant from an axis of rotation, the circular mount structure is rotatably supported by the circumferential bearings, and the support assembly is configured for mounting on the circular mount structure.

An automatic apparatus used for installing a goods delivery terminal comprising a plurality of transporting modules, the transporting module is provided with a first guide rail. The automatic apparatus comprises a sliding assembly. After the transporting modules are joined and installed, the sliding assembly can slide upwards or downwards along the first guide rails from a side of one transporting module to a side of another transporting module. The automatic apparatus further comprises a holding component, a moving mechanism and an operating assembly. The holding component is used for holding the transporting module. After the sliding assembly slides to a position at or near the top portion of installed transporting module, the moving mechanism is used for moving the transporting module to be installed to a position right above the installed transporting module. The operating assembly is used for enabling and/or disabling fixed connection of the adjacent transporting modules.

In several embodiments, the disclosed process may include installing one or more householder devices onto load-bearing structures of a building, installing one or more perimeter beams onto the one or more householders, installing a new exterior assembly onto the one or more perimeter beams, removing an existing roof, and constructing an additional level on the building. In at least one embodiment, installing the one or more householders onto the load-bearing structure may include cutting a hole in the existing roof above the load-bearing structure, attaching the householder onto the load-bearing structure, and sealing the hole around the householder. In some embodiments, the new exterior assembly may be partially or fully constructed on site and may be installed onto the one or more perimeter beams. In some embodiments, once the new exterior assembly is installed, the old roof may be removed from underneath the new exterior assembly.

An apparatus, system, and method for shearing cables, such as those used in concrete support structures, is presented. In one embodiment, an apparatus is presented that can include a casing, a handle, a cutting nose, a torque conversion mechanism, and a cable support. The cable support can be configured to removably couple to a cable, such as to secure the cable within a cable groove of the apparatus. In another embodiment, a system for cable shearing is presented, wherein the system comprises a shearing apparatus and torque-generation apparatus. In another embodiment, a method of clipping cables, such as within a pocket, is presented.
