Construction design of new intelligent glass greenhouse

Date：11-07  Hits：  Belong to：Company News
The design of new intelligent glass greenhouse construction refers to the greenhouse with glass as daylighting material. In the cultivation facilities, the new intelligent glass greenhouse construction design as the longest life of a method, suitable for a variety of areas and various climatic conditions. The new type of intelligent glass greenhouse construction design structure mainly includes greenhouse base, greenhouse steel structure and aluminum alloy structure, greenhouse base 1.5% . The foundation classification, the new Intelligent Glass Greenhouse Construction Design Foundation divides into the Independent Column Foundation and the Strip Foundation two kinds. The independent base can be used for inner or side columns, and the strip base is mainly used for side walls and inner partitions. 2. Before planning, the geological materials of the construction site should be carefully analyzed. First, the Geological Survey Statement of the site (for important large-scale greenhouse projects) ; Second, the construction site test (for general projects) ; third, based on experience and adjacent projects of the reference geological material (for small projects) . In the foundation planning, besides meeting the requirements of strength, it should also have the ability of meeting the requirements of stability and resisting uneven settlement, the foundation connected with the inter-column support should also have the satisfactory effect of transmitting horizontal force and spatial stability. The bottom of the greenhouse should be located below the frozen soil layer. The influence of heating on the frozen depth of the root can be considered according to the climate and soil condition. In general, the base of the root should be less than 0.5 m above the outdoor ground, and the distance between the top of the root base and the outdoor ground should be more than 0.1. Rice to avoid root exposure and adverse effects on culture. Except for special requirements, the distance between the bottom and top of the greenhouse and the indoor floor should be greater than 0.4 m.
The embedded parts connected with the greenhouse steel structure are all arranged at the top of the root, and the planning of the embedded parts is also an important part of the root planning. The main methods of connecting the buried parts to the superstructure are articulation, consolidation and elastic articulation, and the planning and structural methods are different depending on the method of articulation, but all buried parts must ensure excellent connection with the foundation, and ensure that the forces from the superstructure are properly transmitted to the base. 3. Root materials and construction features (1) independent root. The general use of reinforced concrete. From the construction method points, the independent foundation is divided into full cast-in-place and part of the cast-in-place two methods. All cast-in-place selection of the construction site formwork, all pouring method; part of the cast-in-place method to select the base short column prefabricated, base cushion on-site pouring method. Two methods can be chosen according to the specific situation.
The cast-in-place method has the characteristics of good overall quality and low cost, and some cast-in-place methods have high cost but high construction speed and easy construction quality. (2) strip bottom. Generally choose masonry structure (brick, stone) , construction also choose site masonry method, often set a reinforced concrete ring beam at the top of the root to install embedded parts and increase the root stiffness. In addition, the side wall foundation can also choose the Independent Foundation and the Strip Foundation mixed use method, two kinds of foundation foundation bottom can be located at the same elevation, can also be set at different elevation according to the bearing status and effect; The independent base bears the force from the bottom of the greenhouse column, and the strip base is only used as part of the separating member. (3) matters needing attention in construction. During the foundation construction, the column height and Axis orientation should be correct, and the equipment, pipe openings and devices should be buried in time.
