The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of modular stairway, comprise handrail, junction plate, gripper shoe and connecting rod, fixedly connected with described handrail in the upper end of the gripper shoe of homonymy, described junction plate is provided with at least two junction plate fixing holes along its length, in the described junction plate fixing hole at least one is the junction plate holddown groove that extends along its length, the bottom of described gripper shoe is provided with at least two and the corresponding gripper shoe fixing hole of described junction plate fixing hole along its length, in the described gripper shoe fixing hole at least one be extend along its length with the corresponding gripper shoe holddown groove of described junction plate holddown groove, the bottom of described gripper shoe and described junction plate juxtaposition are fixedly connected on the end of described connecting rod.
Described junction plate is provided with three junction plate fixing holes along its length, two in the described junction plate fixing hole is the junction plate holddown groove that extends along its length, the bottom of described gripper shoe is provided with three gripper shoe fixing holes along its length, and two in the described gripper shoe fixing hole is the gripper shoe holddown groove that extends along its length.
Described junction plate is provided with a junction plate fixing hole and two junction plate holddown grooves along its length, described junction plate fixing hole is arranged on the centre of described junction plate, described two junction plate holddown grooves are separately positioned on the end at the two ends of described junction plate, the bottom of described gripper shoe is provided with a gripper shoe fixing hole and two gripper shoe holddown grooves along its length, and described two gripper shoe holddown grooves are separately positioned on the both sides of described gripper shoe fixing hole.
Described junction plate is provided with a junction plate fixing hole and two junction plate holddown grooves along its length, described junction plate fixing hole is arranged on an end of described junction plate, described two junction plate holddown grooves are separately positioned on centre and the other end of described junction plate, the length that is arranged on the junction plate holddown groove of described junction plate end is the twice that is arranged on the length of the middle junction plate holddown groove of described junction plate, the bottom of described gripper shoe is provided with a gripper shoe fixing hole and two gripper shoe holddown grooves along its length, described gripper shoe fixing hole is arranged on the bottom of described gripper shoe, described two gripper shoe holddown grooves all are arranged on the top of described gripper shoe fixing hole, are twice near the length of the gripper shoe holddown groove of described gripper shoe fixing hole away from the length of the gripper shoe holddown groove of described gripper shoe fixing hole.
Compared with prior art, advantage of the present utility model is that the gripper shoe fixing hole of bottom of gripper shoe and in the junction plate fixing hole on the junction plate at least one are configured to gripper shoe holddown groove and the junction plate holddown groove that extends along its length respectively, when forming stair with such gripper shoe and junction plate, connecting rod can move in gripper shoe holddown groove and junction plate holddown groove, as long as connecting rod is arranged on corresponding position in gripper shoe holddown groove and the junction plate holddown groove, do not need crooked junction plate just can constitute spiral stair, and can regulate easily at height and width equally, and do not need to increase other part between handrail and the junction plate, simple in structure, easy for installation, can be applicable to multiple occasion.
