Example one

As shown in fig. 1, an assembled steel-concrete structure stair comprises a bottom plate 7, wherein a sliding plate 11 is slidably connected to the left side of the bottom plate 7, specifically, a cavity is formed inside the bottom plate 7, the sliding plate 11 is inserted into the cavity, a guide rail can be arranged at the bottom of the cavity, and a pulley is arranged at the bottom of the sliding plate to realize the sliding of the sliding plate 11, such as the structure of an existing drawer. The bottom of the sliding plate 11 is rotatably provided with a pulley 12. The top plate 1 is horizontally arranged above the bottom plate 7, and a stair body is obliquely arranged between the bottom plate 7 and the top plate 1. The stair body comprises two groups of side plates 10 which are arranged in parallel, the number of each group of side plates 10 is two, and the two side plates 10 in each group are arranged in parallel. Two ends of the four side plates 10 are respectively hinged on the top plate 1 and the sliding plate 11. The bottom plate 7 is vertically provided with a support column 3, a slide rod 2 is vertically connected in the support column 3 in a sliding manner, and the top end of the slide rod 2 is hinged on the top plate 1. A plurality of fixing holes are formed in the supporting column 3 and the sliding rod 2, and bolts are connected in the fixing holes in a threaded mode to connect the supporting column 3 and the sliding rod 2. The height of the top plate 1 can be adjusted by adjusting the length of the sliding rod 2 extending out of the supporting column 3, so that the high end of the stair body is pulled to move, and the low end of the stair body pulls the sliding plate 11 to move together when the high end of the stair body moves, so that the height of the stair body is adjusted.

A handrail 4 is arranged above each group of side plates 10 in parallel, a plurality of vertical rods 8 are vertically arranged between the handrail 4 and the side plates 10, and two ends of each vertical rod 8 are respectively hinged on the handrail 4 and the side plate 10 which is positioned above the handrail 4 in the figure 1. A plurality of pedals 9 are horizontally arranged between the two groups of side plates 10, four corners of each pedal 9 are respectively connected with a rotating shaft, holes matched with the rotating shafts are formed in positions corresponding to the four side plates 10, the rotating shafts are rotatably connected in the holes, and the pedals 9 are rotatably connected. So set up, the stair body is when adjusting, and montant 8 can remain vertical state throughout, and footboard 9 can keep the horizontality to the user uses. The pedal 9 is of a steel-concrete structure, specifically, the pedal 9 is a shell formed by steel plates, and concrete is poured in the shell. So set up, on the one hand the cost-effective, on the other hand can improve the intensity and the holding power of footboard 9.

The bottom welding of support column 3 has integral key shaft 5, has seted up mounting groove 6 on the bottom plate 7, and the sculpture has a plurality ofly and integral key shaft 5 complex spline on the 6 inner walls of mounting groove. So set up, can realize being connected with dismantling of bottom plate 7 with support column 3. The top end of the sliding rod 2 is hinged to the top plate 1, and the top rod of the sliding rod 2 is provided with a locking mechanism for locking the sliding rod 2, as shown in fig. 2, the locking mechanism in the embodiment comprises a threaded rod 16 in threaded connection with two sides of the top end of the sliding rod 2, and the bottom of the top plate 1 is provided with a threaded hole 15 for connecting the threaded rod 16.

The specific implementation process is as follows:

in the initial state, the stair body, the sliding rod 2 and the supporting column 3 are all folded on the bottom plate 7. During assembly, the bottom plate 7 is arranged on the plane of a lower-layer building, and the top plate 1 is used for being connected with the upper-layer building. The lower end of the support column 3 is inserted into the mounting groove 6, the slide rod 2 is rotated to be in a vertical state, and the threaded rod 16 at the top of the slide rod is screwed into the threaded hole 15 in the top plate 1, so that the slide rod 2 is fixed, and the slide rod 2 is prevented from swinging. When the height of the stair body needs to be adjusted, the sliding rod 2 is pulled manually to move in the vertical direction, so that the top plate 1 is driven to move up and down. The high end of roof 1 pulling stair body reciprocates, because stair body length is fixed, so the low end of stair body can pull slide 11 and move on the horizontal direction. Therefore, the inclination of the stair body is adjusted, and the span of the stair body in the vertical direction, namely the height, is adjusted to meet the use requirements of the stairs in floors with different heights. After the slide bar 2 is adjusted, the fixing holes in the slide bar 2 are aligned with the fixing holes in the support columns 3, and then bolts are screwed into the fixing holes, so that the slide bar 2 and the support columns 3 can be connected, the position of the slide bar 2 is fixed, and the positions of the top plate 1 and the stair body are further fixed.

During transportation, the supporting column 3 is taken out of the mounting groove 6, and the threaded rod 16 is screwed out of the threaded hole 15 to release the sliding rod 2. Then the slide bar 2 is rotated to the lower part of the stair body, the lower end of the stair body is pulled leftwards, and the stair body is rotated to the horizontal state from the inclined state and is horizontally placed on the bottom plate 7. So can effectually reduce the holistic volume of stair, be convenient for transportation and hoist and mount.

Example two

As shown in fig. 3, the difference between the first embodiment and the second embodiment is that the locking mechanism includes locking rods 14 hinged to both sides of the top end of the sliding rod 2, and a locking groove 13 for accommodating the locking rods 14 is formed at the bottom of the top plate 1. During assembly, the locking rod 14 is rotated to be inserted into the locking groove 13, so that the slide rod 2 can be fixed, and the slide rod 2 is prevented from swinging.

EXAMPLE III

The difference between this embodiment and the first embodiment is that the bottom plate 7 and the sliding plate 11 are provided with accommodating grooves for accommodating the supporting columns 3 and the sliding rods 2, and the accommodating grooves on the bottom plate 7 and the sliding plate 11 are communicated. When keeping flat the stair body on bottom plate 7, support column 3 and slide bar 2 can be accomodate in the holding tank, further reduce the holistic volume of stair from this, and it is more convenient to transport.

Example four

The difference of this embodiment and embodiment one lies in, has seted up in the bottom plate 7 and has put the thing chamber, puts the thing chamber and runs through bottom plate 7 top, installs the apron that is used for sealed thing chamber of putting on the bottom plate 7, and the apron is articulated or sliding connection is on bottom plate 7. During the transportation, put the thing chamber and can hold support column 3 and slide bar 2, after the assembly was accomplished, put the thing chamber and can also supply the user to deposit article, kill two birds with one stone. Set up the apron and cover and put the thing chamber, avoid article to pollute on the one hand, on the other hand can improve the holistic pleasing to the eye degree of stair.
