Example (b):

as shown in fig. 1 to 5, the stair structure adopting the plastering-free block of the present invention comprises a support rib 1, a plastering-free block 2 and a wall 3, wherein a part of the support rib 1 is horizontally embedded into the wall 3, and the plastering-free block 2 is horizontally and fixedly sleeved on the support rib (1); the wall body 3 is provided with a plurality of support ribs 1 according to the size requirement of the stair steps, and the plurality of support ribs 1 are fixedly sleeved with the plastering-free building blocks 2 to form the stair steps. In this embodiment, the support rib 1 is used for providing an installation place for the plastering-free block 2, ensuring the installation stability of the plastering-free block 2, and simultaneously ensuring that the plastering-free block 2 can form a stair step structure of a stair after being installed, so that the support rib 1 can be equivalently replaced by a member capable of supporting the plastering-free block 2, such as a support plate; in the embodiment, the support rib 1 is embedded into the wall body 3, the support rib 1 is limited by the wall body, so that the support rib 1 can provide a support force meeting the normal use of the stair, the support rib 1 can be arranged in a preset mode and a post-arranged mode, the preset mode is that the support rib 1 is embedded into the wall body 3 in advance when the wall body 3 is constructed, and then the support rib 1 is fixed in the wall body 1 in a pouring mode, and the mode has the advantage that the support effect of the support rib 1 on the plastering-free building block 2 is better, but the mode is not convenient for the later stage of needing to adjust the step position of the stair due to actual construction; the postposition mode is that after the wall 3 is constructed, when the stair construction is needed, the wall 3 is punched to embed the support rib 1 into the wall 3, or the support rib 1 is anchored on the wall 3, and the mode of the postposition support rib 1 has the advantage that the setting position of the support rib 1 can be determined according to the specific construction condition of the stair construction compared with the mode of presetting the support rib 1. The plastering-free building block 2 adopted in the embodiment replaces the traditional brick, because the surface of the plastering-free building block 2 is originally flat and does not need to be plastered and leveled, and the plastering-free building block 2 also has the advantages of high hardness, light weight, heat preservation, heat insulation and the like, and can effectively realize the function required to be realized by the traditional brick at the position. Compared with the traditional construction mode of a cast-in-place stair, the construction mode of the embodiment is simpler in structure and less in construction procedures, the stair construction workload can be reduced, the difficulty of stair construction can be reduced, and the input of stair construction can be reduced, meanwhile, the plastering-free building block 2 adopted in the embodiment can effectively avoid the procedure of plastering and leveling, and due to the structural characteristics of the plastering-free building block 2, construction such as tiling can be directly performed on the surface of the plastering-free building block 2 after the plastering-free building block is completely installed, so that the construction investment can be effectively shortened, and the construction benefit and efficiency can be further improved.

Each layer of ladder step is horizontally provided with two or more than two support ribs 1. In order to reduce consumptive material reduce cost when guaranteeing the normal safe use of stair in this embodiment, all set up two brace rods 1 with the wall body level perpendicularly to every layer of ladder step, thereby two brace rods 1 can restrict to exempt from to plaster building block 2 and can not take place to rotate and cause the accident under the condition of atress when satisfying the supporting role to exempting from to plaster 2 vertical side of building block. Meanwhile, the number of the support ribs 1 can be more than two, the support ribs 1 can not be arranged in the same horizontal plane, as long as the support ribs 1 can effectively support the plastering-free building block 2, the plastering-free building block 2 can be guaranteed to have the function of serving as a stair step after being stressed, and as equivalent replacement, the support ribs 1 can also be structures which can meet requirements such as support plates.

The plastering-free building block 2 is provided with two or more than two supporting holes 21 along the long axis direction, and the plastering-free building block 2 is sleeved on the supporting ribs 1 through the supporting holes 21. When the plastering-free building block 2 is installed, the supporting hole 21 and the supporting rib 1 are reinforced by a cementing material. In this embodiment the setting position of brace rod 1 on wall body 3 still need satisfy the setting position of brace hole 21 on the block 2 of exempting from to plaster, need guarantee exempt from to plaster block 2 can be smooth and satisfy the cover of demand on brace rod 1, still should consolidate with cementitious material at brace hole 21 and brace rod 1's contact site when exempting from to plaster block 2 installation in addition, guarantee the stability of structure, the cement thick liquids that this preferred job site of cementitious material can make things convenient for the acquisition very much. The design of the support hole 21 is matched with the support rib 1, so that the plastering-free building block 2 can be accurately sleeved and fixed on the support rib 1, and the installation requirement is met.

A convex block 22 is arranged on one side surface of the plastering-free building block 2, and a groove 23 is arranged on the other side surface of the plastering-free building block 2; the convex block 22 and the groove 23 are respectively positioned on two opposite end surfaces of the plastering-free building block 2; when two adjacent non-plastering blocks 2 are connected through the convex block 22 and the groove 23, the two adjacent non-plastering blocks 2 can form a flat step surface. And the adjacent plastering-free building blocks 2 are connected by adopting a cementing material. In order to improve the connectivity of two adjacent non-plastering blocks 2, the two opposite sides of the non-plastering block 2 are respectively provided with a convex block 22 and a groove 23, when two adjacent non-plastering blocks 2 are connected, one of the convex blocks 22 can be perfectly embedded into the other groove 23, after the convex block 22 is matched with the groove 23, the connection between the two adjacent non-plastering blocks 2 is further enhanced, and the connection between the two adjacent non-plastering blocks 2 is reinforced by cement in the embodiment, so that the structure safety is improved.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above description is only the embodiments of the present invention, and is not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
