The utility model discloses a fast installation magnetic type LED line lamp which comprises an installation shell, magnetic suction boxes are fixedly installed at the two ends of the installation shell, four round through holes are formed in the top of each magnetic suction box, a rotating cavity is formed in each magnetic suction box, four adsorption magnets are fixedly installed in each magnetic suction box, and the adsorption magnets are arranged in the rotating cavity. A rotating block is rotationally mounted in the rotating cavity; by rotating a hand-rotating button, a rotating column drives a rotating block to rotate, so that a polycarbonate magnetic resistance plate is driven to rotate in a rotating cavity, the polycarbonate magnetic resistance plate and an adsorption magnet are staggered, the polycarbonate magnetic resistance plate does not shield the adsorption magnet, and then the device is close to a position needing to be installed. The device can be attracted and installed on the surface of an iron object with the preset installation position through the attraction magnet, so that the LED line lamp is installed at the needed position, and stable installation can be achieved without any additional fixing tool or complex operation.

This invention relates to the field of fencing technology, specifically disclosing a collision-resistant and buffer-type safety fence, comprising: a fixed pile mechanism, which includes a square hole, a circular hole, a hemispherical groove, a hollow cylindrical tube, and a fixed pile body. Two hollow cylindrical tubes are respectively located on the left and right sides of the top of the fixed pile body. A square hole communicating with the inner cavity of each hollow cylindrical tube is opened in the center of its front side. Circular holes penetrating vertically are opened on both the left and right sides of the bottom of the fixed pile body. Two hemispherical grooves are equidistantly spaced along the circumference at the top of the inner cavity of the fixed pile body. This device is not only easy to install and disassemble, and has excellent buffering performance, but also possesses good environmental adaptability, economy, and reusability. It fundamentally solves the problems of irreversible deformation, difficult maintenance, and inconvenient assembly and disassembly of traditional rigid guardrails, providing an efficient, flexible, and reliable solution for construction safety protection.

This invention relates to the field of concrete construction technology and discloses a formwork support device for concrete pouring construction. It includes two mutually rotatably connected support rods and corner pieces rotatably installed at the ends of the support rods. Both ends of the two support rods are telescopically adjustable. The corner pieces have two rotatably adjustable corner plates that abut against the two sides of the corner of the formwork. A stepped surface is formed on the outer wall of the corner plate, and a support plate abuts between the two opposite stepped surfaces of adjacent corner pieces, with the support plate in close contact with the formwork. This invention can flexibly adapt to various angles of window corners, including acute, right, and obtuse angles. Simultaneously, by utilizing diagonal support to form a closed force transmission path from the center to the four corners, it can further improve the versatility and overall rigidity of the support device, thereby preventing deformation of the window corners.

The invention relates to the technical field of building decorative walls, and particularly discloses a construction method of an assembly type decorative shared wall, which comprises three steps of factory modular prefabrication production, field installation and lossless disassembly and assembly and recombination. A factory adopts a steel plate component assembling mold to form a gel coat outer layer, silica powder cellulose foaming cement is filled and maintained, a cavity, a gel coat surface layer and silica powder cellulose foaming cement are formed through steel plate injection, and finally a finished wallboard with concave-convex structures on the two sides and an inner through oval pipeline is manufactured. Heaven and earth components are positioned and installed on site through infrared rays, the wallboards are assembled in a sliding and meshed mode through a mortise and tenon joint structure, water, electricity and circulating air systems are integrated in internal pipelines, component installation grooves are reserved in the wallboards, and the wallboards can be reused in a lossless mode during disassembly and assembly. The problems that a traditional partition wall is long in construction period, large in waste, high in transformation destructiveness, irreversible, low in integration degree and the like are solved, the technical effects of efficient construction, environment friendliness and flexible layout can be achieved, and the partition wall is suitable for various building decoration indoor partition wall projects.
