Description

Technical Field

[0001] This invention relates to the field of cement board production technology, and in particular to a rapid paving cement board and its production process. Background Technology

[0002] After cement pavement is laid, the curing time is relatively long, which affects its service life. It is also affected by climate and temperature. Common cement pavement does not have internal reinforcement structures during the laying process, which can easily lead to cracks and bulges after long-term use. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the above-mentioned technologies. The technical solution adopted by this invention is as follows:

[0004] A rapid paving cement board, characterized in that it comprises a cement board, a reinforcing structure, lifting rings, a square steel mesh, grooves II, and anti-slip horizontal stripes. The reinforcing structure includes horizontal and vertical steel bars, with three vertical steel bars welded to one side of two horizontal steel bars. Two reinforcing structures are provided inside the cement board. The bottom ends of four lifting rings pass through the cement board and are connected and fixed to the reinforcing structures upwards. Four grooves II are provided on the upward side of the cement board, all located at the positions of the four lifting rings. The square steel mesh is pressed onto the downward side of the cement board, and multiple anti-slip horizontal stripes are pressed onto the upward side of the cement board.

[0005] A rapid paving cement board production process, characterized by comprising the following raw materials in parts by weight: cement, sand, gravel, recycled and crushed waste cement blocks, cement additives, water, and fly ash.

[0006] The specific production process includes the following steps:

[0007] (5) Place the raw materials in the required proportion into the drum mixer and mix them.

[0008] (6) Place the mixed raw materials into the hydraulic press and vibrate to form the shape;

[0009] (7) The crane is used to load the railcar into the heat treatment solidification workshop for high-temperature curing and cooling hardening.

[0010] (8) Enter the processing workshop for shaping and finishing, and refine the shape according to the customer's construction requirements.

[0011] As an improvement, the length of the horizontal steel bar is greater than that of the vertical steel bar, the two horizontal steel bars are placed relatively parallel, and the three vertical steel bars are all equally spaced and parallel.

[0012] As an improvement, the two reinforcing structures are placed parallel to each other vertically and are positioned close to the top and bottom surfaces of the cement board. The four ends of the two reinforcing structures are all located inside the cement board and are positioned close to the four sides of the cement board.

[0013] As an improvement, the upper-layer reinforcement structure is provided with clips and buckles respectively, the two horizontal steel bars are provided with two clips and two buckles at each end, and the three vertical steel bars are provided with three clips and three buckles at each end.

[0014] As an improvement, each side of the cement board is provided with a groove, which is located at both ends of the two horizontal steel bars and the three vertical steel bars in the upper reinforcement structure.

[0015] As an improvement, the ratio of the recycled crushed cement, sand, gravel and waste cement blocks is 1:1:2.5:3.5, with appropriate amounts of water, fly ash and cement additives.

[0016] As an improvement, the step involves applying intense vibration for 10 minutes.

[0017] As an improvement, the high-temperature curing time in the above steps is 10 hours, and the cooling and hardening time is 7 hours.

[0018] The beneficial effects of this invention are as follows:

[0019] This invention relates to a rapid paving cement slab and its production process. The road surface is constructed by splicing multiple cement slabs together, making installation convenient and quick. The cement slabs are pre-processed into finished products, which are then spliced ​​and fixed together during use, eliminating the need to wait for the cement to harden and shortening construction time. The cement slabs have two layers of reinforcement structure inside, increasing their strength and preventing breakage and bulging. This allows for immediate road opening after paving, facilitating subsequent maintenance. The slabs also have a long service life, saving financial expenditure and labor costs. This effectively solves the construction obstacles caused by prolonged road construction and helps reduce urban construction waste. Attached Figure Description

The bottom ends of the four lifting rings (5) pass through the cement board (1) and are connected and fixed to the reinforcement structure (2) upward. The cement board (1) is provided with four groove two (10) upward, and is set at the four lifting rings (5). The grid steel mesh (8) is pressed on the cement board (1) downward, so that the cement board (1) can better solidify with the auxiliary material, grip the ground tightly, and make the cement block (1) more solid and durable after solidification. The cement board (1) is pressed with multiple anti-slip horizontal lines (11).

[0030] The production process of rapid paving cement slabs is characterized by including the following raw materials in parts by weight: cement, sand, gravel, recycled and crushed waste cement blocks, cement additives, water, and fly ash. The ratio of cement, sand, gravel, and recycled and crushed waste cement blocks is 1:1:2.5:3.5. Appropriate amounts of water, fly ash, and cement additives are added. The required proportions of raw materials are placed inside a drum mixer for mixing. The mixed raw materials are then placed inside a hydraulic press for vibration molding, subjected to high-intensity vibration and pressing for 10 minutes, and finally transported by overhead crane to a railcar for high-temperature solidification in a heat treatment and solidification workshop. After 10 hours of curing and 7 hours of cooling and hardening, the cement board is moved to the processing workshop for shaping and finishing according to the customer's construction requirements. The cement board 1 is then transported to the construction area. A hoisting device is used to connect the cement board 1 to the lifting ring 5 on top. The cement board 1 is then placed on the road surface where it needs to be spliced ​​and installed. When in use, the cement boards 1 are interlocked together so that the clips 6 on the adjacent cement boards 1 engage with the clips 7 on the adjacent cement boards 1. Then, the lifting ring 5 is bent into the groove 2 10. The groove 2 10 is smoothed with cement. Then, multiple grooves 1 9 are smoothed with cement in sequence.
