Description

Technical Field

[0001] This invention relates to the field of construction safety devices, specifically a safety protection device for construction near stairwells. Background Technology

[0002] Prefabricated construction refers to transferring a large amount of on-site work from traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. Prefabricated buildings mainly include precast concrete structures, steel structures, and modern wood structures. Because they employ standardized design, factory production, assembly-based construction, information management, and intelligent applications, they represent modern industrialized production methods. In prefabricated buildings, the installation of precast stairs is always slower than that of cast-in-place structures, and the stairs cannot reach the construction work surface, making edge protection of stairwells particularly important.

[0003] Most current edge protection systems are constructed using steel pipes and fasteners. However, edge protection systems using steel pipes and fasteners require a large number of components to assemble, resulting in low construction efficiency, complicated disassembly, and inconvenience in relocation. Therefore, a new type of safety protection device for stairwell edge construction is needed to solve these problems. Summary of the Invention

A connecting ring is fixedly connected to the middle of the outer wall of the sliding column. The connecting ring is located to the left of the compression spring. Limit strips are fixedly connected to both ends of the left side of the sliding column. A limit groove is provided on the bottom right side of the first fixed column.

[0008] Preferably, the movable deployment mechanism includes two telescopic columns, one end of each of the two telescopic columns is fixedly connected to the interior of two crossbars on opposite sides, a return spring is provided on the outer wall of each telescopic column, a limit plate is fixedly connected to the other end of each telescopic column, a connecting rod is fixedly connected to one side of the limit plate, a nut is threaded to the middle of the outer wall of the connecting rod, a limit plate is fixedly connected to one end of the outer wall of the connecting rod, and a side column is slidably connected to the left side of the outer wall of the connecting rod through a through groove.

A locking block is rotatably connected to the top of one side of each telescopic crossbar via a rotating rod. A locking groove is provided at the bottom of one side of each telescopic crossbar. Telescopic rods are fixedly connected to the bottom sides of the first fixed column and the top sides of the second fixed column. A spring is provided on the outer wall of each telescopic rod.

[0010] Preferably, both sides of the slots of the first and second fixing posts are provided with straps for limiting and fixing.

[0011] Preferably, a threaded rod is threadedly connected to one side of the inner side of the fixed base, a fixed frame is slidably connected to the middle side of the outer wall of the threaded rod, a fastening nut is threadedly connected to the bottom side of the outer wall of the threaded rod, and the fixed frame is located below the fixed base.

[0015] Working Principle: During use, the disassembly and assembly mechanism allows the fixed base and fixed column one to be separated. For disassembly, first rotate the handle 90 degrees, pulling the handle to move the sliding column outwards, causing the limit strip to slide out of the limit groove, completing disassembly. Installation is similar. By rotating the fastening nut, it loosens and disengages from the threaded rod. After moving the fixing bracket to a suitable position at the bottom of the stair side, rotate the fastening nut to clamp it. At this point, the fixed base is at the top of the stair side, and the fixing bracket is at the bottom, clamped and fixed by the threaded rod and fastening nut. A horizontal connecting piece can be added to connect the fixed bases on both sides, enhancing stability. After fixing, pull the horizontal bar one outwards to disengage it from the inside of fixed column one and fixed column two. After rotating a certain degree, it... The return spring is used for limiting the movement, and the crossbar 2 is pulled to both sides, allowing the side column to be connected through the telescopic column 2, return spring 2, limit plate 2, connecting rod, and through groove. After being disengaged from the interior of the crossbar 2 and rotated a certain angle, it is limited and further fixed by nuts. At this time, the two opposing telescopic crossbars inside the side column are opened by the pivot, and the corresponding locking blocks on the telescopic crossbars are locked to the outer wall of the fixed column 2. Then, the telescopic rod and spring drive the locking plates to move up and align with the locking grooves on the telescopic crossbars to complete the fixation. This protective device is easy to store and move, avoiding the trouble of disassembly and transportation. At the same time, the device can be adjusted to a certain tilt angle during use, which can be adapted to stairs with different inclines. It can also be used for planar protection, expanding its application range.

[0016] This invention provides a safety protection device for construction near the edge of stairwells. It has the following beneficial effects:

[0017] 1. The present invention makes the protective device easy to store and move by setting up a storage mechanism, avoiding the trouble of disassembly and transportation. Through the cooperation of telescopic column one, return spring one and turntables on both sides, the crossbar one can be inserted into the fixed column one and fixed column two, and stored according to the actual situation, which facilitates movement and turnover.

[0018] 2. The present invention, through the setting of the disassembly and assembly mechanism, allows the fixed base and the fixed column to be separated, which facilitates the use of different models of fixed bases to connect the fixed column to the support surface, and further facilitates movement and turnover.

[0019] 3. The present invention, through the setting of the movable unfolding mechanism, enables the side columns on both sides to open, thereby forming a protective device, and at the same time, it can be adjusted to a certain extent for convenient use.

[0020] 4. The present invention, through the setting of the snap-fit ​​mechanism, enables the telescopic crossbar to be fixed while also allowing for a certain degree of tilt angle adjustment, making it easy to adapt to stairs with different inclines. It can also be used for planar protection, thus expanding its scope of application. Attached Figure Description

After moving the fixing bracket 6 to a suitable position at the bottom of the side of the stairs, it is clamped by rotating the fastening nut 32. At this time, the fixing base 4 is located at the top of the side of the stairs, and the fixing bracket 6 is located at the bottom of the side of the stairs. It is clamped and fixed by the threaded rod 5 and the fastening nut 32.

[0045] The top of the fixed column 2 and the two side columns 24 are all equipped with anti-collision pads 3 to prevent collision damage.
