Embodiment Construction
[0053] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 As shown, a steel plate surface layer method for heavy-duty air-floating floors, including the following steps:
[0054] 1) Obtain steel plates that meet the requirements according to size and quality;
[0055] (1) The length of each steel plate is 8000mm, the width is 2000mm, and the thickness is 20mm. It is required that the levelness error of the steel plate is less than 1mm / 2m within the normal range;
[0056] (2) The surface of the steel plate is smooth, showing metallic luster, without rust and corrosion;
[0057] (3) The groove size and precision of the steel plate meet the welding requirements.
[0058] 2) Check the flatness / levelness of the concrete base floor
[0059] The ground level error is less than 2mm / 2m. If the error exceeds this range, the concrete layer construction unit must grind the surface to within the allowable error range.
[0060] 3) Open pre-embedded reinforc...

Abstract
The invention relates to a heavy-load type air floatation terrace structure, in particular to a steel plate surface layer structure and method for the heavy-load type air floatation terrace. The method comprises the following steps that 1) a steel plate meeting the requirements is acquired according to the size and the mass; 2) the flatness / levelness of the concrete terrace is inspected, wherein the ground level error is less than 2mm / 2m; (3) pre-embedded steel bar planting holes are opened, (4) pre-embedded part steel plates are laid, (5) steel bars are planted, (6) the pre-embedded steel plates are laid, (7) a surface layer steel plate is laid and tailor-welded, and (8) a polyurethane surface layer is brushed. The steel plate surface layer structure and method for the heavy-load type airfloatation terrace which can meet the requirements for terrace surface layer flatness, cracks, tensile strength and compression resistance when an air cushion vehicle runs are provided.
Description
technical field [0001] The invention relates to a heavy-duty air-floating floor structure, in particular to a steel plate surface layer structure and a method for a heavy-duty air-floating floor. Background technique [0002] Manufacturing enterprises that manufacture products with large weight or large dimensions usually use large-tonnage air-cushion vehicles for transportation in the workshop or across the workshop. Certain flatness, smoothness, compressive strength, tensile strength, most of the current air-floating floor surface layer is implemented on the reinforced concrete base layer to implement the epoxy self-leveling flat layer to meet the requirements of the air-cushion vehicle. However, the inherent cutting joints, expansion joints and natural cracks of the concrete base will cause the epoxy surface to crack, resulting in the inability of the hover vehicle to run smoothly, damage to the airbag and increased maintenance costs.
