Description

Technical Field

[0001] The utility model relates to the technical field of stairs, in particular to an assembled prefabricated staircase. Background Art

[0002] Stairs are an important part of house construction. They are a transportation hub that solves the vertical connection between different floors and are the main passage for people besides elevators. With the development of the construction industry, prefabricated stairs are gradually replacing the traditional method of on-site construction of concrete stairs due to their advantages such as high installation efficiency and fast construction speed.

[0003] In the Chinese utility model patent application disclosure specification CN218990715U, although it solves the problem that when installing a circular staircase, the pedals need to be installed at equal intervals on the vertical rod in the middle, in order to ensure the effect of the circular staircase, it is necessary to accurately control the spacing between adjacent pedals. The existing technology uses manual measurement and then supports the pedals for welding, but it is not easy to install and it is inconvenient for users to go up and down the stairs when carrying heavy objects. Therefore, a new utility model is needed to solve this problem. Utility Model Content

[0004] The purpose of the utility model is to provide an assembled prefabricated staircase to solve the problems raised in the above background technology.

[0007] Furthermore, the installation mechanism includes an installation groove, an installation block, and a clamping groove. An installation groove is opened on one side inside the two fixed blocks, an installation block is fixedly installed on one side of the two beam bodies, a clamping groove is opened on one side of the top of the two installation blocks, and the installation block is arranged inside the installation groove.

[0008] Furthermore, the fixing mechanism includes a fixing groove, a block, and a spring. A fixing groove is opened at the top of the two installation grooves, a block is arranged inside the two fixing grooves, the bottom end of the block is arranged inside the slot, and a spring is arranged at the top of the block inside the two fixing grooves.

[0009] Furthermore, the limiting mechanism includes a limiting groove and a limiting block. The limiting grooves are provided on both sides of the fixing groove, and the limiting blocks are provided on both sides of the clamping block. The limiting blocks are provided inside the limiting grooves.

[0010] Furthermore, the pushing mechanism includes a support plate, a placement plate, a motor, a threaded rod, a pushing block, a limit rod, and a control button. A support plate is provided at the top of each of the two beam bodies, a placement plate is provided between the two support plates, a motor is installed on one side of the support plate through a mounting seat, a threaded rod is provided at the output shaft end of the motor through a rotating shaft passing through the support plate, a pushing block is provided on the outer side of one end of the threaded rod through a threaded hole, a limit rod is provided at one end of the pushing block through the mounting hole, and a control button is provided at the top of each of the two support plates.

[0013] Furthermore, the surfaces of several of the steps are provided with anti-slip grooves.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The assembled prefabricated staircase uses a hoisting device to align the installation block with the installation slot and push it inward. Since the clamping block is a single-sided trapezoidal setting, the installation block will make the clamping block move upward and squeeze the spring. When the clamping block and the clamping slot are on the same vertical line, the clamping block will be clamped into the inside of the clamping slot under the action of the spring, thereby completing the fixation. The stairs can be quickly installed, the workload is reduced, the work efficiency is increased, and the economic cost is reduced.

[0016] The assembled prefabricated staircase can be used to carry heavy objects on the push block when the user is carrying heavy objects to climb the stairs, and then the control button is activated to start the motor. The output shaft end of the motor will drive the threaded rod to rotate, so that the threaded rod drives the push block to move upward. Some users find it inconvenient to carry heavy objects when going up and down the stairs. The push block is used instead of manual carrying, so that the user can carry heavy objects up and down the stairs more easily, and can also avoid injuries caused by stepping on empty space due to inconvenience in movement when carrying heavy objects.
