This invention discloses a universal concrete slab system with no-removal bottom formwork, its construction method, and a carbon emission reduction calculation method, belonging to the field of prefabricated building technology. The core system consists of prefabricated no-removal bottom formwork units, a coordinating load-bearing steel reinforcement skeleton, a post-cast composite concrete layer, and a support and force transmission system. These are fixedly connected to bidirectional reinforcing bars via embedded connectors to form a coordinating load-bearing skeleton, ensuring a firm bond between the prefabricated bottom formwork and the post-cast layer, creating an overall load-bearing structure with the same strength as a fully cast-in-place slab of the same thickness. The prefabricated bottom formwork can be finished with white cement, achieving a unified attribute of temporary formwork, permanent structure, and finished decorative surface. The supporting construction method is designed to fit the specific characteristics of the system, significantly simplifying construction procedures. The carbon emission reduction calculation method is tailored to the dual / triple attributes of the no-removal bottom formwork, with specific calculation rules. This invention features a safe and reliable structure, wide applicability, and outstanding green and low-carbon effects, making it suitable for various civil and industrial building projects and complying with dual-carbon policy requirements.

This invention provides a high-level photovoltaic module installation platform and its construction method, relating to the field of photovoltaic construction and installation. The high-level photovoltaic module installation platform includes end longitudinal beams at both ends, a middle longitudinal beam, and a connecting crossbeam. The connecting crossbeam is fixedly connected to the end longitudinal beams at both ends. The middle longitudinal beam supports and fixes the connecting crossbeam. When moving the construction platform, the middle longitudinal beam enables the lateral sliding of the supporting connecting crossbeam. After the photovoltaic panels are installed in the construction area, the connecting crossbeam can be automatically transferred by removing and installing the middle longitudinal beam, allowing the construction platform to continuously advance and move to different construction areas. Since most photovoltaic installations are linearly distributed, the construction area can be continuously changed without dismantling the original scaffolding, achieving high efficiency, uninterrupted construction, and better economic benefits.

This invention discloses scaffolding for arch ribs of arch bridges, relating to the field of scaffolding technology. The invention includes four scaffolding poles and two frame plates. Two limiting holes are provided at one end of each scaffolding pole. Two connecting sleeves are provided on the lower surface of each frame plate. One end of each scaffolding pole is in movable contact with the inner wall of the connecting sleeve. U-shaped sleeves are provided on both sides of each frame plate. The surface of the connecting sleeves is provided with a disassembly and assembly mechanism for assembling and disassembling the scaffolding poles. A fixing mechanism is provided inside the U-shaped sleeve. By rotating a lead screw, the lead screw drives a second slider to move horizontally along the inner wall of a second sliding groove. The second slider moves the scaffolding poles horizontally through the connecting sleeves, thus facilitating the horizontal displacement of the scaffolding. This allows construction workers to stand on the scaffolding and perform construction work at different locations on the two arch ribs of the arch bridge. Simultaneously, it effectively reduces the amount of scaffolding used during construction and effectively reduces the time required to erect the scaffolding.

This invention relates to a construction method for a large-span Bailey bridge connecting corridor based on the Midas model, belonging to the field of large-span connecting corridor technology. The method includes: analyzing the stress on the basement roof slab based on the positioning coordinates of pre-embedded steel plates, drawing a foundation node layout diagram, and welding double-section steel foundation beams to form a force-transfer frame. This frame is vertically assembled with Bailey panel columns to form Bailey column units, and adjacent units are horizontally connected using channel steel connecting rods to construct a support skeleton. The stress and deformation of this skeleton are calculated using Midas software to obtain verification data, based on which Bailey crossbeams and longitudinal beams are hoisted to establish a high-altitude load-bearing platform. Finally, the platform is fixed to the I-beam distribution beams using clamping plates to create a distribution beam support layer. Based on this layer, a disc-lock scaffold is erected to complete the construction of the connecting corridor pouring platform. This method solves the problem that existing technical solutions often lack effective utilization assessment of underground space, leading to potential insufficient foundation bearing capacity during construction.
