The most basic configuration of glass greenhouse is external shading system, internal shading system, fan water curtain cooling ventilation system, top window ventilation system, surrounding and top covering materials, greenhouse skeleton and so on. After the greenhouse site selection, the first thing to do is the foundation construction. According to the load-bearing foundation of the greenhouse, the cost per square meter will be 30 to 40 yuan.
Extended data:
Basic materials and structural features:
( 1)? Independent foundation. Reinforced concrete is usually used. From the construction method, the independent foundation is divided into two ways: full cast-in-place and partial cast-in-place. The full cast-in-place is supported by formwork and cast as a whole at the construction site.
The cast-in-place part adopts the method of prefabrication of foundation short columns and on-site pouring of foundation cushion. These two methods can be selected according to the specific situation. The cast-in-place method has the characteristics of good integrity and low cost; Cast-in-place method has high cost, but the construction speed is fast and the construction quality is easy to ensure.
(2) Strip foundation. Masonry structure (brick, stone) is usually adopted, and site masonry is also adopted for construction. Reinforced concrete ring beams are often set at the top of the foundation to install embedded parts and increase the stiffness of the foundation. In addition, the side wall foundation can also be mixed with independent foundation and strip foundation, and the bottom surfaces of the two foundations can be located at the same elevation.
Can also be set at different elevations according to bearing conditions and functions; The independent foundation bears the force from the bottom of the greenhouse column, and the strip foundation is only used as a part of the partition member.
(3) Matters needing attention in foundation construction. During foundation construction, the correctness of column height and axis position should be ensured, and the opening and installation of equipment and pipelines should be embedded in time. It is forbidden to chisel away the damaged foundation after construction.
