A kind of mechanized bolt fastening device for narrow space assembled building module and its using method, comprising: spanner chassis, the top of spanner chassis is fixedly installed with inverted L frame, first gear is rotated by reduction drive assembly, then the first gear of rotation synchronously drives first transmission rod and first rocker at the bottom of first transmission rod, so that transmission rod produces swing, then the transmission rod of swing is driven again in the action of first limiting rod, second limiting rod and sliding groove, drives ratchet spanner and spanner sleeve to move in 30 ° active range and continuously tightens bolt, so that the overall use of the device is light, meet in narrow range Construction, and can be translated and taken out, meet the functional requirements of once living of full renovation building, can achieve module building with hoist and install, improve connection efficiency, reduce operation time, shorten project construction period, greatly reduce on-site construction, improve overall assembly rate.

The present application relates to photovoltaic power generation integrated technical field, and disclose a kind of breath type cooling double waterproof unit photovoltaic power generation integrated roof system and process, the system includes several unit modules and roof structure;The unit module includes metal roof panel and at least two thin-film photovoltaic panels arranged in series, the length direction of the thin-film photovoltaic panel is fixedly connected along the top end of metal roof panel wave crest by structural adhesive, the gap between the two adjacent thin-film photovoltaic panels is sealed by weather-resistant sealant to form double waterproof, the lower surface of the thin-film photovoltaic panel and the wave valley area of the metal roof panel are enclosed to form breath type cavity extending continuously along the length direction of metal roof panel, form chimney effect to quickly export heat, effectively reduce the temperature of thin-film photovoltaic panel, guarantee power generation efficiency, achieve excellent heat insulation.The breath type cooling double waterproof unit photovoltaic power generation integrated roof system and process have the advantages of factory modular assembly processing, on-site rapid installation, improving building assembly rate, etc.

The utility model discloses a kind of steel outer package type sound insulation assembly type wall connecting structure, it is related to assembly type building wall technical field, technical scheme is, including wall, center fixed connecting piece, high-strength tie rod;Four adjacent walls are connected by the center fixed connecting piece, wall four edges are provided with center fixed connecting piece connecting groove, round recess is provided at wall four corners, center fixed connecting piece center is equipped with hollow cylinder, round recess size is 1 / 4 hollow cylinder, high-strength tie rod is set in hollow cylinder, high-strength tie rod both ends are provided with backing plate and high-strength bolt.The beneficial effects of the utility model are: the scheme is provided with sound insulation cotton at connecting place, solve the problem that traditional connection mode is poor in sound insulation effect at joint, ensure the sound insulation effect of wall joint, also ensure the sound insulation effect of whole wall.

This utility model discloses a shaft pre-embedded support scaffolding component, the structure of which includes: bolts, angle steel support components, and I-beams. The bolts transversely penetrate the upper middle and lower left and right sides of the angle steel support components and are spaced together with the I-beams. The I-beams are vertically embedded inside the angle steel support components and their bottoms overlap with those of the angle steel support components. This utility model further improves the process of erecting scaffolding using segmented I-beams by further improving the shaft pre-embedded scaffolding component. It can be used for different elevator shaft sizes, and is fixed to the inner wall of the elevator shaft with pre-embedded bolts. It is easy to assemble and disassemble on site and can be reused in different projects. It is low in cost, highly practical, and has a high assembly rate. It also features convenient construction, easy assembly and disassembly, fast construction speed, shortened construction cycle, high efficiency and economy, convenient turnover, safety and reliability, and green environmental protection.
