Abstract

The utility model discloses a prefabricated staircase finished product protection device, and relates to the field of prefabricated stairways. The prefabricated staircase finished product protection device comprises a plurality of corner protection plates, wherein the corner protection plates are tightly attached to the edges of the prefabricated staircase, and a connecting unit is arranged between two adjacent corner protection plates. This prefabricated staircase finished product protection device, the tight laminating of angle bead board can effectively disperse external force in prefabricated staircase's edges and corners department, prevents that the stair edges and corners from damaging because of collision, rubs, extension stair life. The connecting unit is used for firmly connecting two adjacent corner protection plates through the combination of the transverse strip, the vertical strip and the connecting block to form an integral protection structure. The stability of the protection device is enhanced, the protection range is enlarged, the stair corner angle is protected in all directions, and the connecting block is used as a connecting pivot of the transverse strip and the vertical strip, so that the flexible rotation and connection of the transverse strip and the vertical strip are realized.

Description

Prefabricated staircase finished product protection device Technical Field The utility model relates to the technical field of prefabricated stairways, in particular to a prefabricated staircase finished product protection device. Background In the production, transportation and installation processes of the prefabricated stairway, the edge angle part of the stairway is extremely easy to collide and rub due to the protruding structure, so that the prefabricated stairway is damaged. The damage of the edges and corners not only affects the attractiveness of the stair, but also can weaken the structural strength of the stair, and the service life of the stair is reduced. Therefore, the effective protection of the prefabricated stair corner is particularly important. The traditional protection method for the edges and corners of the prefabricated staircase is mainly to simply wrap the prefabricated staircase by using materials such as wood plates, foam and the like. However, the method has the defects that the protective material is easy to fall off, the protective effect is not durable, the method is difficult to adapt to stair corner angles with different sizes and shapes, and the universality is poor. Therefore, there is an urgent need for a prefabricated staircase finished product protection device that is stable in structure, convenient to install, and reusable. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a prefabricated stair finished product protection device, which solves the problem that the traditional prefabricated stair corner protection method is mainly used for simply wrapping by adopting materials such as wood plates, foam and the like.
