The invention discloses a reinforcing rib pressing machine for color steel tiles and a method for using the same, and relates to the technical field of color steel tile processing, in particular to a steel plate body and a size adjustment assembly, and a first movable bracket is arranged under the right end of the steel plate body , the output end of the first motor is connected with a first gear, the bottom of the hydraulic press is connected with a second movable support, the output end of the second motor is connected with a second gear, and the second gears are connected by The second transmission belts are connected to each other, and the size adjustment assembly is arranged on one of the main lower pressing roller and the main supporting pressing roller. The reinforced rib pressing machine for color steel tiles and its use method can carry out pressing operations for steel plate bodies of different widths by adjusting the width dimensions of the main support pressure roller and the main lower pressure roller, and repair the steel plate body after pressing In order to improve the aesthetics and improve the size accuracy, the width of the main support roller and the main lower roller can be reduced to the minimum when idle, so as to reduce the volume and facilitate storage.

The invention relates to the technical field of traffic road paving, and discloses a stone slab building block paving structure suitable for traffic loads at all levels. The upper surface of the soilbottom layer is covered with a fine stone concrete layer, the upper surface of the fine stone concrete layer is covered with a sand stone soil layer, the upper surface of the sand stone soil layer isprovided with a fixing component, the upper surface of the fixing component is provided with a building block stone slab component in an embedded mode, and the upper surface of the fixing component isprovided with a fixing anchor rod. According to the structure, the structural strength of paved stone slab building blocks can be increased by arranging the building block stone slab component, the pressure born by the paved stone slab building blocks is increased, the generation of cracks in the surfaces of the paved stone slab building blocks is reduced, the surfaces of the paved stone slab building blocks are provided with anti-slip grooves, the slip of pedestrians can be avoided, and the safety is increased; and the fixing component can maintain the integrity of the shapes of the paved stone slab building blocks when the paved stone slab building blocks are damaged and broken, the pavement is prevented from being uneven and is free of pits, and water accumulating in the rainy days isavoided.

The invention relates to the field of buildings and particularly relates to a production method of sand blast fair-faced concrete. The production method comprises the following steps of a, carrying out sand blast treatment on a molding surface of a mould, wherein the particle size of the blasted fine sand is smaller than 1.5mm, and the color of the sand blasted on the molding surface of the mould is uniform; b, placing a steel reinforcement cage into the mould; c, pouring the stirred concrete into the mould, and screeding the upper surface of the concrete in the mould; and d, dismounting the mould after the strength of the concrete meets the requirement, and spraying a protective agent on the fair-faced surface of the molded concrete to obtain the sand blast fair-faced concrete. The fine sand is sprayed on the molding surface of the mould, and flaws on the molding surface of the mould are removed, so that the molding surface of the mould is more smooth and is uniform in color, pot holes in the surface of the concrete are avoided, the concrete is molded at one time without mending, the concrete is kept uniform in veneering color and free of air bubbles and has a matting effect, the construction cost is further reduced, and the work efficiency is increased.
