The invention provides a double T-shaped composite beam provided with prestressed steel tube concrete core rods, which is formed by utilizing the prestressed steel tube concrete core rods as tensioned lower flanges, adopting corrugated steel plates as web plates and pouring an upper flange top plate with high-strength concrete. The prestressed steel tube concrete core rods consist of steel tubes, intra-tube concrete and prestressed steel bars, and have high tension capacities; as the prestressed steel tube concrete core rods are combined with the corrugated steel web plates for use, the advantages are complemented, the shear capacity and flexural capacity of a crossbeam are improved, and the crossing ability of the crossbeam is improved. The composite beam has the advantages of light weight, great crossing ability, high bearing ability, high stiffness, low cost and the like, can be suitable for volume production in prefabricated part factories, can serve as a roof beam for constructing a 30-48m oversized-span single-storey industrial factory building, and as a floor beam for constructing a 21-30m large-span multi-storey industrial factory building, meets the requirements of industrial production on a large space, and saves land.

The invention provides a torsion-resisting deformation-resisting 360-degree rotary welding locating tool for a lower cross beam. The torsion-resisting deformation-resisting 360-degree rotary welding locating tool for the lower cross beam comprises supporting stand columns, a rotating platform and portal mechanisms. The rotating platform is provided with a welding station corresponding to the lowercross beam. The rotating platform is installed on the two supporting stand columns. The supporting stand columns are provided with servo motors used for driving the rotating platform to rotate. The portal mechanism are installed on the rotating platform. A welding station is located below the portal mechanisms. Jacks are arranged on the portal mechanisms and used for tightly pressing the lower cross beam. The welding station is provided with a fixing hole corresponding to the lower cross beam. A back cover plate of the lower cross beam penetrates through the fixing hole to reach other side ofthe rotating platform, and this side of the rotating platform is provided with a reversible deformation pre-making mechanism. According to the torsion-resisting deformation-resisting 360-degree rotary welding locating tool for the lower cross beam, the tool rotates, so that weld joints on the front side, back side, left side and right side of the lower cross beam are conveniently welded; the reversible deformation pre-making mechanism can pre-make reversible deformation of materials to counteract deformation generated after welding, and unnecessary adjusting and finishing are reduced.

The invention discloses a fabricated bridge substructure which comprises a foundation structure, a prefabricated bent cap and a quasi-prefabricated pier column unit, and foundation reserved vertical ribs are arranged at the top of the foundation structure; cover beam reserved vertical ribs are arranged on the lower side of the prefabricated bent cap. At least one sprue gate vertically penetrating through the prefabricated bent cap is arranged in the area covered by the reserved vertical ribs of the bent cap; a standard prefabricated pier column unit is a hollow cylinder with openings in the upper portion and the lower portion and penetrates through the foundation reserved vertical ribs to be vertically inserted into the top of the foundation structure; the prefabricated bent cap is in lap joint with the top of the standard prefabricated pier column unit and extends into the hollow area of the standard prefabricated pier column unit through the cover beam reserved vertical ribs to be connected in an inserted mode. Expansion concrete is cast in situ in the sprue gate and the hollow area of the standard prefabricated pier column unit. The construction quality can be controlled in a cast-in-place and prefabricating combined mode, investment of formworks is omitted, the weight is low, installation is convenient and rapid, the aerial work time can be effectively shortened, the construction efficiency is improved, and the construction period is shortened.

The invention belongs to a fireproof isolation device, and particularly relates to a double-layer battery prefabricated cabin structure with a fireproof isolation function, which comprises two batteryprefabricated cabins arranged up and down and independent from each other and a fireproof isolation space, wherein the upper-layer battery prefabricated cabin in the two battery prefabricated cabinsis mounted above the lower-layer battery prefabricated cabin in a suspended manner, so that a fireproof isolation space is formed between the upper-layer battery prefabricated cabin and the lower-layer battery prefabricated cabin; and the fireproof partition plate is mounted in the fireproof isolation space. In conclusion, the double-layer prefabricated cabin can achieve fire prevention and explosion prevention after the energy storage cabins are arranged in a stacked mode.

The invention discloses an intelligent power equipment installation and lifting device, the structure of which comprises casters, a bottom plate, a drive box, a scissor bracket, a movable frame, and a lifting structure. , the scissor-type bracket is embedded and installed between the drive boxes, the movable frame is hinged to the upper end of the scissor-type bracket, and the lifting structure is fixedly installed on the upper end of the movable frame. The lifting structure includes a longitudinal movable structure, a lateral movable structure, a lateral movable plate, Universal wheels, the horizontal movable structure is horizontally installed on the upper end of the longitudinal movable structure, and the lateral movable plate is fixedly installed on the upper end of the horizontal movable structure. The expenditure of manpower makes the installation more convenient; a horizontal movable structure is set at the lower end of the horizontal moving plate, which can better adapt to the power equipment of different widths, thereby reducing the working intensity and facilitating the lifting installation of the power equipment.

The invention discloses a sliding rail of a Christmas tree lowering guide tool. The sliding rail is vertically arranged between a drilling table of a semi-submersible platform and a lower trolley in a moon pool area of the semi-submersible platform. A head structural component and a tail structural component are included in the two longitudinal sides and are two square steel pipes arranged side by side in a spaced manner. A common pipe head and pipe tail are fixedly connected to the upper ends and the lower ends of the two square steel pipes. The tail structural component is a connecting rod of an upper base and a lower base. The head structural component is a motion guide rail of a guide arm sliding base. The upper base, the lower base and the guide arm sliding base each comprise a back plate. A function groove of the sliding rail is formed by a longitudinal clearance between the head structural component and the tail structural component of the sliding rail in space and comprises locating mounting grooves of the upper base back plate and the lower base back plate, a movable connecting groove and a longitudinal sliding groove, wherein the movable connecting groove and the longitudinal sliding groove are between the guide arm sliding base and the sliding rail.
