Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular to a method for constructing a steel plate ultra-flat ground for a dark riding device. Background Technology

[0002] Ultra-flat floor construction technology is widely used in building construction, primarily in amusement facilities, logistics companies, large warehousing centers, and large forklift transportation in supermarkets—buildings with extremely high requirements for floor flatness. For example, dark rides in amusement parks integrate multi-degree-of-freedom motion vehicles, intelligent bionic robots, 3D giant screen stereoscopic movies, vertical lifting systems, and themed landscaping decorations. Their required floor flatness is 2 / 3000, meaning the height difference within a 3-meter area should not exceed 2 millimeters, which qualifies as an ultra-flat floor. Currently, large-area ultra-flat floor construction mainly utilizes laser leveling machines for automated leveling, while small-scale construction relies primarily on manual labor combined with high-precision levels, high-precision screeds, and formwork systems. However, for dark rides in amusement parks, it is necessary to construct a curved, ultra-flat floor indoors, which requires the support of curved formwork. This necessitates the overall design and construction of the formwork, as well as the control of key nodes in the measurement and control process of the curved formwork. In addition, the formwork construction and leveling process of the ultra-flat concrete floor is relatively complex, resulting in a long construction cycle and low construction efficiency. Summary of the Invention

[0003] In view of the above problems, the purpose of this invention is to provide a method for constructing a steel plate ultra-flat ground for dark riding equipment, which can reduce the construction difficulty and installation accuracy requirements of ultra-flat ground, and greatly improve the installation efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A method for constructing a steel plate ultra-flat ground for a dark riding device includes the following steps:

[0006] A. Divide the entire project into several construction sections, each of which is in a straight line and / or curved shape;

[0007] B. Concrete construction of the super-flat ground bottom structure within each construction section.

[0008] Reinforcing bars are tied to the ground, the casting formwork is installed and fixed, and then concrete is poured. Two first protrusions and one second protrusion are formed at the top of the construction section. The second protrusion is located between the two first protrusions, and a vertical guide plate is pre-embedded at the top of the second protrusion.

[0009] C. Construct the super-flat ground sections within each construction segment.

[0010] Construction is carried out above the first protrusion using a super-flat device. This device includes a horizontal steel plate with two rows of adjusting devices on its bottom surface, arranged along the length of the plate. Each adjusting device includes a U-shaped channel steel with a through hole at its top. An adjusting nut is fixed to the top surface of the through hole, and an adjusting bolt is installed inside the adjusting nut. A positioning nut is fitted onto the adjusting bolt. The bottom of the channel steel is fixedly connected to the top surface of an anchor plate, and an anchor bolt is fixedly installed at the bottom of the anchor plate. The top of the adjusting bolt is fixedly connected to the bottom surface of the horizontal steel plate. Several U-shaped anchor bars are located on the bottom surface of the horizontal steel plate, between the two rows of adjusting devices. Step C includes:

[0011] C1. Weld the anchor bolt and the anchor plate together, drill an anchor hole on the first protrusion, pour chemical mortar adhesive into the anchor hole, put the anchor bolt into the anchor hole, adjust the height of the anchor plate, and ensure that the elevation error in the forward direction of the dark riding equipment is less than 2mm every 3m, and the elevation error perpendicular to the forward direction of the dark riding equipment is less than 2mm.

[0012] C2. Then weld the channel steel onto the anchor plate;

[0013] C3. Next, weld the adjusting nut onto the top of the channel steel and align the hole of the adjusting nut with the through hole on the channel steel;

Screw the adjusting bolt into the adjusting nut, adjust the height of the upper surface of all adjusting bolts and check to ensure that the elevation error in the forward direction of the dark riding equipment is less than 2mm every 3m, and the elevation error perpendicular to the forward direction of the dark riding equipment is less than 2mm.

[0015] C5. After the top elevation of all adjusting bolts has passed inspection, tighten the positioning nuts on the adjusting bolts to prevent them from loosening, and measure again whether there is any change in the height of the upper surface of each adjusting bolt.

[0016] C6. After the adjustment device passes inspection, the horizontal steel plate and the anchor bar are welded together and laid on top of the adjustment bolts to ensure that the elevation error of the horizontal steel plate in the direction of the dark riding equipment is less than 2mm every 3m, and the elevation error perpendicular to the direction of the dark riding equipment is less than 2mm. The horizontal steel plates on both sides are laid with the center of the guide plate as the reference plane, and the error perpendicular to the direction of the dark riding equipment is not greater than 3mm.

[0017] C7. After passing the inspection, weld the lower surface of the horizontal steel plate to each adjusting bolt, and check the error of the horizontal steel plate again.

[0018] C8. After passing the inspection, install the casting template on both sides of each first and second protrusion and carry out secondary casting. When casting above the first protrusion, fill the entire area under the horizontal steel plate and make the surface flush with the surface of the horizontal steel plate; when casting above the second protrusion, make the surface flush with the surface of the horizontal steel plate.

[0019] Preferably, the concrete strength grade for pouring is C30, and the water-cement ratio is below 0.50; the concrete slump requirement on site is: the final slump shall not exceed 110±5% mm; and the air content in the concrete shall not exceed 3.0%.

[0020] Preferably, the coarse aggregate of the concrete used for pouring is 5mm-25mm, and the sand is medium sand, which is either natural yellow sand or manufactured sand made of pebbles.

[0021] The beneficial effects of the present invention are: the steel plate ultra-flat ground construction method of the dark riding equipment of the present invention utilizes a construction device with stable structure and adjustable height, which reduces the construction difficulty and installation accuracy requirements, and greatly improves the installation efficiency.
