Description

Technical Field

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

[0002] Stairs are components used for vertical transportation between floors in a building. They are used for transportation when there is a large height difference between floors. Traditional stairs are mostly supported by cast-in-place cement concrete. This type of staircase is strong, but has a long production cycle, complex production process, and cannot be disassembled.

[0003] As disclosed in Chinese patent announcement No. (CN214575218U), an assembled staircase comprises several groups of upper platforms and several groups of stair sections which are detachably connected from top to bottom in sequence, several support columns being connected to the lower surface of the upper platform, and the stair section comprising two mutually parallel side panels and a plurality of pedals for walking up and down, the side of the pedal close to the stepping part when walking up and down being the stepping end, the pedal being rotatably connected between the two side panels, and the pedal and the side panels being an interference fit, a plurality of blocking members being fixed between the two side panels, the blocking members abutting against the pedal and blocking the pedal from rotating downward on the side close to the stepping end. This application has the effect of not requiring the pedal and the side panels to be reinstalled during assembly, and making the assembled staircase installation simpler and more convenient.

[0004] However, the above patent still has the problem of poor fixed support effect for assembled stairs. In the above patent, the stair plate and the support plate are connected by bolts, and the stairs need to maintain high-strength support to ensure that the stairs will not collapse. The connection method using only bolts is likely to cause the stair plate to deviate and rotate along the bolts, affecting the assembly stability of the stairs. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an assembled staircase having the advantages of good fixed support effect, etc., and solves the problem of poor fixed support effect for assembled stairs in the prior art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembled staircase, comprising two assembly uprights, an assembly mechanism for stably assembling the staircase is provided on opposite sides of the assembly uprights, and a support mechanism for improving the support effect is provided on opposite sides of the assembly mechanism;

[0007] The assembly mechanism includes four slide bars, two fixed plates, two support frames and a ladder plate. Two slots are provided on opposite sides of the two assembly vertical plates. The four slide bars are slidably connected to the inner walls of the two slots on the front and rear sides respectively. The two fixed plates are respectively fixed to the opposite sides of the slide bars on the front and rear sides. The two support frames are respectively fixed to the opposite sides of the two fixed plates. The ladder plate is fixed to the upper surfaces of the two support frames.

[0008] Furthermore, the length of the ladder plate is greater than the width of the assembly vertical plate, and the support frame is triangular.

[0009] Furthermore, the width of the slide bar is equal to the distance between the inner walls on the left and right sides of the slot.

[0010] Furthermore, two connecting screw holes are provided on one side of the fixing plate opposite to the assembly vertical plate, and the internal threads of the connecting screw holes are connected with fixing bolts.

[0011] Furthermore, the support mechanism includes fixing holes opened on opposite sides of the two fixing plates, and support holes corresponding to the positions of the fixing holes are opened on opposite sides of the two assembly vertical plates, and support beams are inserted into the support holes and the inner walls of the fixing holes, and studs are fixed to the left and right ends of the support beams, and baffles are slidably connected to the outer sides of the two studs, and fastening nuts are threadedly connected to the outer sides of the two studs and on the side opposite to the two baffles.

[0012] Furthermore, two plug pins are fixed on opposite sides of the two baffles, and plug holes corresponding to the positions of the plug pins are opened on opposite sides of the two assembly vertical plates.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. The assembled staircase is provided with an assembly mechanism, wherein the assembly vertical plate is provided with a slot, and the slide bar is slidably connected to the inner wall of the slot, so that the stair plate can be adjusted and fixed between the assembly vertical plates. The support frame and the fixing plate provide a stable connection between the stair plate and the assembly vertical plate. The stair plate is fixed to the upper surface of the support frame to form the steps of the staircase. The support frame is triangular, providing better support effect and stability. Two connecting screw holes are provided on the side of the fixing plate opposite to the assembly vertical plate, and the internal threads are connected with fixing bolts for firmly connecting the fixing plate to the assembly vertical plate.

[0015] 2. The prefabricated staircase is provided with a support mechanism. The support holes on the assembly vertical plate need to be aligned with the fixing holes on the fixing plate. This is the starting step of the support mechanism installation to ensure that the two can cooperate correctly. After alignment, the two ends of the support beam are respectively inserted into the fixing hole and the support hole. The support beam here serves to connect the two assembly vertical plates and provide additional support. Tightening the nut can increase the stability of the connection and prevent the support beam and the baffle from being displaced during use.

[0026] The working principle of the above embodiment is:

[0027] (1) When assembling and installing the stairs, the assembly vertical plate 1 is provided with a slot 26, and the slide bar 21 is slidably connected to the inner wall of the slot 26, so that the ladder board 24 can be adjusted and fixed between the assembly vertical plates 1. The support frame 23 and the fixing plate 22 provide a stable connection between the ladder board 24 and the assembly vertical plate 1. The ladder board 24 is fixed to the upper surface of the support frame 23 to form the steps of the stairs. The support frame 23 is triangular, providing better support effect and stability. The fixing plate 22 is provided with two connecting screw holes on the side opposite to the assembly vertical plate 1, and the internal thread is connected with a fixing bolt 25 for firmly connecting the fixing plate 22 to the assembly vertical plate 1.

[0028] (2) When the staircase is assembled and installed to improve the support stability, the support hole 32 on the assembly vertical plate 1 needs to be aligned with the fixing hole 31 on the fixing plate 22. This is the starting step of the installation of the support mechanism 3 to ensure that the two can fit correctly. After alignment, the two ends of the support beam 33 are respectively inserted into the fixing hole 31 and the support hole 32. The support beam 33 here serves to connect the two assembly vertical plates 1 and provide additional support. The baffle 35 is connected to the support beam 33 through the stud 34 and can slide along the stud 34 within a certain range to adjust and fix the position of the support beam 33. The fastening nut 36 is tightened on the outer side of the stud 34. Tightening the nut can increase the stability of the connection and prevent the support beam 33 and the baffle 35 from being displaced during use. The plug pin 37 on the baffle 35 is inserted into the plug hole 38 on the assembly vertical plate 1 to further fix the position of the baffle 35 and ensure the stability of the entire support mechanism 3.
