Description

Technical Field

[0001] The utility model relates to the technical field of staircase surface decoration, and particularly relates to a paving structure for bricks on the surface layer of a steel structure staircase. Background Art

[0002] With the rapid development of the construction industry and the acceleration of the urbanization process, steel structures have been widely used in construction projects due to their advantages such as light weight, high strength, and fast construction speed. However, in the surface treatment of steel structure staircases, especially in brick paving, the traditional direct paving method is adopted. Due to the smooth and non-absorbent surface of the steel plate, as well as poor anti-vibration and sound insulation effects under the influence of vibration, the facing bricks paved on the steel staircase treads are extremely prone to problems such as hollowing, loosening, even falling off and cracking. There are also problems of poor durability and complex construction, which affect the use effect and safety. With the increasingly wide application range of steel structure staircases, the surface treatment methods of steel structure staircases on the market are gradually increasing. Commonly used methods include paving the surface layer of steel staircases through steel mesh sheets, but they generally have problems such as high specific gravity, high cost, complex construction, and poor bonding effect.

[0003] Therefore, it is necessary to develop a new type of paving structure for bricks on the surface layer of a steel structure staircase, which can simplify the construction process, avoid problems such as hollowing, loosening, even falling off and cracking of the facing bricks, so as to improve the construction efficiency, durability and aesthetics of the staircase, reduce the construction cost, and meet the market demand for high-quality and high-safety staircases. Summary of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, a paving structure for bricks on the surface layer of a steel structure staircase is provided. Its structural design is simple and reasonable, the construction process is simple, it can avoid problems such as hollowing, loosening, even falling off and cracking of the facing bricks, improve the construction efficiency, durability and aesthetics of the staircase, and reduce the construction cost.

[0005] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] A paving structure for bricks on the surface layer of a steel structure staircase includes a steel staircase tread, a steel bar support framework, a bidirectional steel wire mesh, cement mortar, and facing bricks. The steel bar support framework is welded with steel bar support legs. One side of the steel bar support framework is welded to the bidirectional steel wire mesh, and the long side is welded to the steel staircase tread. The bidirectional steel wire mesh is tied at the L-shaped external corner intersection of the steel staircase tread. The cement mortar is poured through both sides of the bidirectional steel wire mesh, one side is attached to the steel staircase tread, and the other side is attached to the facing bricks.

[0007] Further, the steel bar support framework is made of φ10-φ12 steel bars, with dimensions adapted to the double-sided wire mesh. The overall structure is in a "mesh" shape and is fixedly connected by welding the long vertical line on one side of the "mesh" to the steel staircase tread plate.

[0008] Further, the grid of the double-sided wire mesh is a square with a side length of 1 cm - 2 cm. The size of the double-sided wire mesh is 3 - 5 cm smaller than the length of the steel staircase tread plate in the length direction and 2 - 3 cm wider than the width of the steel staircase tread plate in the width direction.

[0009] Further, the steel bar support legs are arranged in two rows, parallel to the long side direction of the steel bar support framework, located below the steel bar support framework, with a height of 1 - 2 cm. The first row is located at the intersection of the long vertical line and the short horizontal line of the "mesh", and the distance between the second row and the first row is 2 - 3 cm smaller than the width of the steel staircase tread plate.

[0010] Further, the facing bricks are made of stone or ceramic tiles.

[0013] 2. In the present utility model, the designed steel bar support framework and double-sided wire mesh can be mass-produced modularly in the factory according to the on-site dimensions of the steel staircase into an integrated structure, and then transported to the construction site for installation and welding fixation. Since the steel bar support framework and double-sided wire mesh are already firmly connected to the steel staircase tread plate, after the cement mortar hardens, it forms an integral body with the steel bar support framework and double-sided wire mesh, which can firmly fix the facing bricks. The overall construction process is simplified, the construction is simple, the construction efficiency is improved, and compared with the steel wire mesh commonly used for the facing brick paving on the steel staircase surface layer at present, it has greater bond strength, better crack resistance, lighter specific gravity and lower cost.

[0023] Furthermore, the steel bar support framework 2 is made of φ10 steel bars, with dimensions adapted to the double - layer steel wire mesh, and the overall structure is in the shape of "eye". It is fixedly connected to the steel staircase tread plate 1 by welding the long vertical line on one side of the "eye" character.

[0024] Further, the grid of the double-sided wire mesh sheet 3 is a square with a side length of 1 cm. The size of the double-sided wire mesh sheet 3 is 4 cm smaller than the length of the steel staircase tread in the length direction and 3 cm wider than the width of the steel staircase tread in the width direction.

[0025] Further, the steel bar support legs 21 are arranged in two rows, parallel to the long side direction of the steel bar support framework, located below the steel bar support framework, with a height of 1 cm. The first row is located at the intersection of the long vertical line and the short horizontal line of the "eye" character, and the distance between the second row and the first row is 2 cm smaller than the width of the steel staircase tread.

The distance between the vertical board of the facing brick and the vertical board of the steel staircase tread is about 50 mm. Fill the gap with cement mortar to make the cement mortar stick tightly to the wire mesh sheet. After leveling with a level and a leather hammer, then lay the flat board of the facing brick. The paving thickness is about 50 mm. The cement mortar should completely cover the wire mesh sheet and be 20 - 30 mm higher. Scrape and level the flat board of the laid facing brick, and knock it flat with a level and a leather hammer. Complete the construction of the facing brick on the tread of the single-layer steel staircase in sequence.
