[0008] Furthermore, the two cross bars include an outer rod body close to the outer side of the step stairs and an inner rod body close to the inner side of the step stairs, and the hooking device hooked on the outer rod body is detachably connected to the step board.

[0009] Furthermore, a locking plate is installed at the bottom of the tread, a locking hole is formed between the locking plate and the bottom of the tread, the supporting beam of the hooking device hooked on the outer rod body is inserted into the locking hole, and the locking plate is installed with a locking piece for locking the supporting beam.

[0010] Furthermore, the middle portion of the locking plate is arched downward to form the locking hole between the locking plate and the step plate.

[0011] Furthermore, a threaded hole is opened in the middle of the locking plate, and the locking member is a threaded locking member, which is screwed into the threaded hole and abuts against the supporting beam.

[0012] Furthermore, an anti-slip strip is provided on the upper surface of the tread.

[0013] Furthermore, the cross bar is arranged along the length of the tread.

[0014] Furthermore, the support beam is arranged along the width direction of the tread.

[0015] Furthermore, both ends of the cross bar are respectively installed on the steel pipe frame.

[0024] Reference Figures 1 to 4As shown, the present invention provides a step staircase, comprising: a tread 1, a crossbar 2 and a hooking device 3.

[0025] The number of the treads 1 is multiple layers. The multiple layers of treads 1 are arranged in a stepped shape. In some embodiments, the multiple layers of treads are arranged in an oblique linear stepped shape; in other embodiments, the multiple layers of treads are arranged in a spiral stepped shape.

[0026] There are two cross bars 2. The two cross bars 2 are arranged below each layer of treads 1 in the same direction.

[0027] There are multiple hooking devices 3. The hooking device 3 includes a supporting beam 31 and a hooking member 32. The supporting beam 31 is supported at the bottom of the step board 1. The hooking member 32 is connected to the first end of the supporting beam 31 and hooked on the cross bar 2. The second end of the supporting beam is placed on the cross bar. The supporting beam and the cross bar are arranged at an angle. The hook opening 320 of the hooking member 32 is arranged toward the inner side of the cross bar 2. The hook opening is the opening of the hooking member. The hook openings 320 of the hooking members 32 of two adjacent hooking devices 3 are arranged opposite to each other to lock the step board to the two cross bars.

[0028] The step staircase of the present invention allows the treads to be conveniently and quickly installed by means of the hook and pull member. In addition, the step staircase is applicable to steel pipe stairs and can be used in a revolving manner, thus saving resources and reducing construction costs. Furthermore, the treads are reinforced by the support beams connected to the hook and pull member, thereby improving the structural strength and rigidity of the treads.

[0029] In order to improve the construction efficiency of the temporary steel pipe staircase, in this embodiment, the two crossbars 2 include an outer rod body a near the outer side of the step staircase and an inner rod body b near the inner side of the step staircase. The outer rod body a is arranged on the guest-facing side of the step staircase (i.e., the side where people go up the stairs), and the inner rod body b is arranged on the guest-facing side of the step staircase. The hooking device 3 hooked on the outer rod body a is detachably connected to the step board 1.

[0030] Specifically, a locking plate 11 is installed at the bottom of the step board 1. A locking hole is formed between the locking plate 11 and the bottom of the step board 1. The supporting beam 31 of the hooking device 3 hooked on the outer rod body a is inserted into the locking hole. The locking plate 11 is installed with a locking piece 12 for locking the supporting beam 31.

[0031] A threaded hole is opened in the middle of the locking plate 11 , and the locking member 12 is a threaded locking member 12 . The threaded locking member 12 is screwed into the threaded hole and abuts against the supporting beam 31 .

[0032] The middle portion of the locking plate 11 is arched downward and forms a locking hole with the step plate 1 .

[0033] The lock plate has a U-shaped arched portion, and a mounting portion is connected to each of the two sides of the arched portion. The mounting plate is provided with a bolt hole, in which a self-tapping screw is screwed, and the self-tapping screw is embedded in the bottom of the step plate. The U-shaped arched portion is provided with the threaded hole.

[0034] As a preferred embodiment, an anti-slip strip 13 is provided on the upper surface of the tread 1 .

[0035] In this embodiment, the crossbar 2 is arranged along the length of the tread 1. The support beam 31 is arranged along the width direction of the tread 1.

[0036] In some embodiments, the step staircase of the present invention further comprises a steel pipe frame. The steel pipe frame is constructed by scaffolding. The steel pipe frame has a plurality of vertical poles, and the two ends of the cross bar are respectively installed on the vertical poles on both sides of the steel pipe frame.

[0037] In some embodiments, both ends of the crossbar of the step staircase of the present invention are embedded in the wall.

[0038] In this embodiment, the support beam 31 and the hook member 32 are integrally formed.
