This invention discloses a prefabricated steel formwork device for concrete encapsulation of drainage pipe socket interfaces, belonging to the field of drainage pipe network construction technology. The device includes a modular steel formwork body customized to the pipe dimensions, pins, manual fixing screws, pin fixing holes, a rear handle, an installation handle, and multiple sets of fixing holes. The pins and fixing holes are located at the junction of the steel formwork body. The manual fixing screws are installed in the pin fixing holes. Multiple sets of handles are located on both sides and the rear of the steel formwork body, and the fixing holes are evenly distributed on the sides and rear of the formwork. During construction, the modular formwork is snapped onto the pipe socket interface, the pins are aligned and positioned, and the screws are tightened to form a whole. Steel rods are inserted through the fixing holes for fixation, and concrete is poured to complete the encapsulation. This invention offers quick installation, precise positioning, firm fixation, and resistance to bulging and deformation, resulting in high-quality concrete molding. It is also easy to disassemble and can be reused multiple times, significantly reducing construction costs and improving work efficiency.

The utility model discloses a plastic film shell assembling structure convenient to dismantle and clean, which comprises a template structure, and the template structure is supported at the bottom of a concrete structure and is divided into a top plate supporting area and a dense rib beam supporting area; through holes are formed in the top plate supporting area and the dense rib beam supporting area, and plugging pieces are arranged at the through holes; after the top plate supporting area and the dense rib beam supporting area are coated with a release agent, the film shell is covered with a thin film, and the thin film is provided with a traction part at the position of the through hole; before the concrete structure is poured, the thin film is pulled by the through holes and is separated from the surfaces of the top plate supporting area and the dense rib beam supporting area. The formwork structure coated with the release agent is covered with a transparent plastic film, the transparent plastic film is pulled out of the through holes after steel bars are bound and before concrete is poured, nuts are screwed, and it is guaranteed that the formwork structure coated with the release agent is clean to the maximum extent; the concrete pouring quality of the ribbed beam and the top plate structure is improved, the probability of later reworking is reduced, and the construction efficiency of the ribbed beam and the top plate structure is improved. In addition, when the formwork structure is dismantled, the plugging piece is screwed off, the through hole is pressurized through the air pump, and dismantling of the formwork structure is facilitated.

The utility model discloses a telescopic independent column steel formwork which comprises four steel formworks which are enclosed into a rectangle, each steel formwork comprises a steel panel, a steel plate flange, a channel steel main rib, double rows of channel steel back ridges and connecting angle steel, two rows of vertical variable cross-section adjusting holes are formed in one side of each steel panel, and plastic blocking caps are arranged in the variable cross-section adjusting holes; when a large size is enclosed, two sides of the connecting angle steel are respectively connected with two adjacent steel plate turnups through bolts, and when a small size is enclosed, the fixed connecting holes of the steel plate turnups are connected with the variable cross-section adjusting holes through bolts, openings of the channel steel main reinforcements face the steel plate turnups, and the channel steel main reinforcements are arranged at a plurality of positions on the back face of the steel panel. The channel steel main ribs are flush with the steel plate flanges, and the double-row channel steel back ridges are welded to the ends of the channel steel main ribs and the ends of the steel plate flanges. The steel formwork can be connected with the connecting angle steel or the variable cross-section adjusting holes by adjusting the turned-over edges of the steel plates, so that the size of an enclosed independent column area is changed.
