The utility model provides a kind of steel structure building installation positioning device, belong to steel structure building construction technical field.The device structure is ingenious, and it is good to guide, it is convenient to clamp, can be flexibly disassembled, it is convenient for engineering construction use.The electric hoist of the device is fixedly installed on the one side board surface of fixed plate, and a plurality of fixed length's pull cable are fixedly connected on the other side board surface of fixed plate, the free end of each fixed length's pull cable is fixedly bolted screw rod, the drum of electric hoist is wound pull cable, and the free end of pull cable on electric hoist is scattered into multiple strands, and the free end end of each pull cable is fixedly bolted clamping assembly.The device clamps more stable, and the pulling capacity is stronger, and the guiding stability is high, and the alignment accuracy is high, and the assembly construction safety is improved.

This invention relates to the field of building electromechanical installation technology, and discloses a BIM-based integrated layout and modular prefabrication and installation system for electromechanical pipelines. The system includes multi-disciplinary pipelines and integrated supports installed under the exterior building roof slab. The integrated supports include columns, combined steel beams, and pipe clamps. The pipe clamps are configured as variable-angle pipe clamp assemblies, comprising a variable-angle base connected to the combined steel beam and a clamp movably connected to the variable-angle base. The clamp has an adjustable degree of freedom to rotate relative to the horizontal direction within the vertical longitudinal section, so that the clamping axis of the clamp is aligned with the inclined axis of the inclined ramp section. This invention achieves zero-collision pre-assembly before construction, eliminates potential hazards from on-site demolition and alteration, precisely ensures the physical clearance height between driveways and parking spaces, and the modular prefabricated variable-angle damping pipe clamps passively adapt to and conform to the 45-degree inclined ramp path adjusted by BIM.

A construction method of an assembly type entrance and exit structure under an inner supporting system comprises the following steps that firstly, a crane installed at the top of a foundation pit is used for hoisting a bottom block of a first ring of a main body structure connecting section into the foundation pit; secondly, bottom blocks of follow-up components are hoisted in till the length of the trolley can fall down, and a walking track and a chain of the trolley are assembled; thirdly, hoisting splicing of the side wall and the top block of the first ring is conducted; fourthly, after the first ring is spliced, hoisting splicing of a side wall and a top block on a bottom plate is conducted subsequently, and splicing of a main body structure connecting section, a civil defense section, a straight section, a corner section, a straight section and an escalator foundation pit section is completed in sequence; 5, the slope lifting sections are spliced, and different slope section heights and lengths are achieved according to modulus combination; and sixthly, the U-shaped open slope lifting section and the U-shaped open section are spliced.
