Embodiment Construction

[0007] The present invention will be further described with reference to the accompanying drawings.

[0008] 1 in the figure is a stair plate, a step 2 is arranged on the stair plate 1, a transverse blind hole 5 is arranged on one side of the step 2, a longitudinal blind hole 7 is arranged in the length direction of the stair plate 1, and the opening of the blind hole 7 is arranged at the bottom of the stair plate 1 At the end part, at least two sling devices are installed in the length direction of the stairs. The sling devices are arranged on the steps, and the two sling devices are evenly distributed in the length direction of the stairs. In the same direction as the width direction of the steps, the positioning pin 14 passes through the through hole 13 provided on the lower end of the screw sleeve 11. The height of the screw sleeve 11 is connected in a T-shape with the length of the positioning pin 14. The upper part of the screw sleeve 11 is provided with a threaded hole 1...

Abstract

The invention provides a prefabricated hollow staircase which comprises a stair tread, the stair tread is provided with steps, one side of each step is provided with a transverse blind hole, the stair tread is provided with a longitudinal blind hole in the length direction, an opening of the longitudinal blind hole is formed in the bottom end of the stair tread, at least two hanging devices are arranged on the staircase in the length direction and are arranged on the steps, the two hanging devices are uniformly distributed on the staircase in the length direction, each hanging device is provided with a positioning pin, the length direction of each positioning pin is the same as the width direction of the steps, the positioning pins penetrate through holes in the lower ends of threaded sleeves, each threaded sleeve in the vertical direction is connected with the corresponding positioning pin in the length direction in a T-type mode, the upper portions of the threaded sleeved are provided with threaded holes, screws are installed in the threaded holes, the outer ends of the screws are connected with hanging rings, the positioning pins and the threaded sleeves are preburied in the steps, and the hanging rings are located on the upper surface of the steps. The prefabricated hollow staircase can overcome defects in the prior art.

Description

technical field [0001] The invention relates to a building prefabricated component, which is a prefabricated hollow staircase. Background technique [0002] Because there are many deficiencies in cast-in-place stairs, this field has provided a variety of technical solutions for industrially manufacturing staircase products in factories in recent years, so that they can be directly installed on buildings for use. However, this kind of staircase has not yet been approved by the art. The main reason is that the weight of the prefabricated staircase is relatively large, and the loading and unloading and installation are complicated, so that the production cost of the prefabricated staircase is higher than that of the cast staircase. Although prefabricated staircases have many advantages, existing prefabricated staircases cannot be popularized due to the disadvantages of loading and unloading and complex installation. Contents of the invention [0003] The purpose of the pres...
