Embodiment 1
[0032] The construction method of a spherical warehouse provided in this embodiment includes the step of constructing the annular foundation, the step of laying the membrane body and the step of spraying a polyurethane layer in the membrane body, and between the step of constructing the annular foundation and the step of laying the membrane body Also include the following steps:
[0033] Measure the position of the reserved hole according to the already designed construction data and mark it on the ground of the ring foundation;
[0034] After the step of laying the membrane body, projecting the position of the reserved hole marked on the ground of the annular foundation onto the membrane body and marking on the membrane body;
[0035] During the step of spraying the polyurethane layer inside the membrane, a mold with pre-reserved holes is placed on the mark and the polyurethane layer is sprayed.
[0036] In the above-mentioned embodiment, the reserved hole mold is placed on ...

Abstract
The invention discloses a spherical silo construction method, and relates to the technical field of building construction. The construction method comprises the steps of a step of ring foundation construction, a step of membrane body laying, and a step of painting a polyurethane coating layer in the membrane body. Between the step of ring foundation construction and the step of membrane body laying, the following steps still exist: measuring the positions of preformed holes, and marking the positions on the ground occupied by the ring foundation, after the step of the membrane body laying is completed, the projections of the positions of the preformed holes which are marked on the ground occupied by the ring foundation are projected to the membrane body, and the projection points on the membrane body are marked accordingly. In the step of painting the polyurethane coating layer in the membrane body, the moulds of the preformed holes are placed at the marked points, and painted with the polyurethane layer and / or a concrete layer, after all the painting work is finished, the moulds of the preformed holes are removed, thus the holes are formed above the silo wall or silo cap of the spherical silo in a manner that the integrity of the polyurethane layer and the concrete layer is not undermined. Not only the material is saved, but also the integrity of the polyurethane layer and the concrete layer is not undermined, the overall stress condition is more uniform, the silo produced by the method is more sturdy and durable, and the service life is longer.
Description
technical field [0001] The invention relates to a construction method for a spherical warehouse, which belongs to the technical field of building construction. Background technique [0002] The spherical thin-shell concrete storage silo is the ideal storage silo with the largest storage capacity per unit area. It has a beautiful appearance, is economical and environmentally friendly; it has a high filling rate and can use the space most efficiently; it has a reasonable structure and the highest pressure on the silo body (the maximum load-bearing capacity on the top of the silo) 500t), anti-corrosion, windproof, rainproof, shockproof, sturdy and durable; fully enclosed, well preventing dust pollution; good temperature insulation and moisture resistance, and will not form water vapor. The shell can be applied to soil 50°C. Due to the adoption of the advanced air film support construction method, the shell construction is almost not affected by the weather, which greatly short...
