Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated stair slabs, in particular to an anti-crack assembled prefabricated stair slab. Background Art

[0002] Prefabricated stair slabs are stair slabs produced in factories or prefabrication sites. They have standardized sizes and structures and can be directly transported to the construction site for installation. The need to use prefabricated stair slabs is to improve construction efficiency, ensure quality consistency and structural stability, reduce on-site pouring procedures and time, thereby speeding up project progress, reducing construction costs, and ensuring the safety and durability of the stairs.

[0003] Existing prefabricated stair slabs include reinforced concrete stair slabs, steel stair slabs and fiberglass stair slabs. Cracks in prefabricated stair slabs may be caused by a variety of factors, such as concrete shrinkage, temperature changes, load effects, foundation settlement or improper structural design. These factors will cause the stair slabs to be affected by internal stress, exceeding their bearing capacity and causing cracks.

[0004] Traditional prefabricated stair treads will produce cracks due to the temperature, process and transportation shaking during preparation, which will affect the quality of the stair treads. Prefabricated stair treads will also produce more cracks due to moisture penetration and cannot adapt to various environments. Therefore, a crack-proof assembled prefabricated stair tread is proposed. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a crack-proof assembled prefabricated stair slab, aiming to improve the problem in the prior art that the prefabricated stair slab is prone to cracks, resulting in low practicality of the device.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a crack-proof assembled prefabricated stair slab, comprising a prefabricated slab, a connecting block 1 being fixedly connected inside the prefabricated slab, a sliding block being fixedly connected to the upper surface of the connecting block 1, a plurality of threaded nails being fixedly connected to the lower surface of the sliding block, a fixed block being fixedly connected to one side of the outer wall of the connecting block 1, the internal thread of the fixing block being connected to the outer wall of the threaded nail, a bearing plate being fixedly connected to a lower surface of the connecting block, a deformation block being arranged inside the bearing plate, a mounting plate being slidably connected to one side of the outer wall of the bearing plate, and a fixing component being arranged inside the prefabricated slab.

[0007] Furthermore, a filling rubber is fixedly connected inside the prefabricated board, one side of an outer wall of the filling rubber is fixedly connected to the inside of the prefabricated board, and a waterproof layer is fixedly connected to the lower surface of the filling rubber.

[0008] Furthermore, a mounting groove is provided inside the prefabricated board, and a mounting groove is provided inside the waterproof layer.

[0009] Furthermore, a plurality of springs are arranged inside the filling rubber, and one end of the spring is fixedly connected inside the prefabricated plate.

[0010] Furthermore, a groove is provided inside the mounting plate, and one side of the outer wall of the bearing plate is slidably connected to the inner wall of the groove.

[0011] Furthermore, a second connecting block is fixedly connected inside the mounting plate, and a lower surface of the sliding block is slidably connected to an upper surface of the second connecting block.

[0012] Furthermore, fixing bolts are arranged inside the mounting plate.

[0013] Furthermore, the plurality of mounting grooves are distributed in a rectangular array inside the filling rubber.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, the mounting plate is installed on the wall in advance, and the bearing plate connected to the prefabricated plate is inserted into the groove. After the prefabricated plate is positioned and installed, the deformation block is squeezed and deformed, so that the bearing plate exerts force on the prefabricated plate and the mounting plate, so that the mounting plate can be tightly attached to the wall to prevent gaps from being generated, and moisture enters the interior of the prefabricated plate to cause cracks in the prefabricated plate, thereby achieving the effect of improving the practicality of the device.

[0016] 2. In the utility model, by arranging filling rubber inside the prefabricated board, moisture is prevented from entering the main part of the prefabricated board, which effectively reduces the possibility of cracks inside the prefabricated board. Then, by arranging springs inside the prefabricated board, the force generated by some vibrations is mitigated, thereby achieving the effect of extending the service life of the stair slab.
