The glass greenhouse structure mainly includes the greenhouse foundation, the greenhouse steel structure and the aluminum alloy structure, etc. The editor below will understand with you.

basis

1. Basic classification: The foundation of the glass greenhouse is divided into independent column foundation and strip foundation. Independent foundations can be used for inner columns or side columns, and strip foundations are mainly used for side walls and inner partition walls.

2. Design requirements: Before the foundation is designed, the geological data of the construction site should be carefully analyzed. One is the geological survey report of the site (for important large-scale greenhouse projects); the other is the construction site test (for general projects) ; The third is based on experience and reference geological data of nearby projects (for small projects). When designing the foundation, in addition to meeting the requirements of strength, it should also have sufficient stability and the ability to resist uneven settlement. The foundation connected with the column supports should also have sufficient horizontal force transmission and space stability. The bottom surface of the greenhouse should be located below the frozen soil layer, and the heating greenhouse can consider the influence of heating on the freezing depth of the foundation according to the climate and soil quality. Generally, the bottom of the foundation should be more than 0.5 meters lower than the outdoor ground, and the distance between the top of the foundation and the outdoor ground should be greater than 0.1 meter to prevent the foundation from being exposed and adversely affecting cultivation. Except for special requirements, the distance between the top surface of the greenhouse foundation and the indoor ground should be greater than 0.4 meters. The embedded parts connected with the steel structure of the greenhouse are all set on the top of the foundation, and the design of the embedded parts is also an important part of the foundation design. The connection methods of embedded parts and superstructure mainly include hinged connection, consolidation and elastic connection. According to the different connection methods, the design and construction methods are also different, but all embedded parts must ensure a good connection with the foundation and ensure that the upper structure is transmitted. The coming power is correctly transmitted to the foundation.

3. Basic materials and construction characteristics

(1) Independent foundation. Reinforced concrete is usually used. From the construction method, the independent foundation can be divided into two methods: full cast-in-place and partial cast-in-place. Full cast-in-place adopts the method of construction site support and integral pouring; part of the cast-in-place method adopts the method of foundation short column prefabrication and foundation cushion on-site pouring. The two methods can be selected according to the specific situation. The cast-in-place method has the characteristics of good integrity and low cost; part of the cast-in-place method has a higher cost, but the construction speed is fast, and the construction quality is easier to guarantee.

(2) Strip foundation. Masonry structure (brick, stone) is usually used, and the construction is also carried out by on-site masonry. A reinforced concrete ring beam is often set on the top of the foundation to install embedded parts and increase the rigidity of the foundation. In addition, the side wall foundation can also be used in a mixed way of independent foundation and strip foundation. The bottom surfaces of the two types of foundations can be located at the same elevation, or can be set at different elevations according to the bearing conditions and functions; the independent foundation undertakes the transmission of the bottom of the greenhouse column. With the coming force, the strip foundation is only used as a part of the partition member.

(3) Precautions for foundation construction. During foundation construction, the correctness of the column height and axis position should be ensured. The equipment, pipe openings and installation should be buried in time, and it is strictly forbidden to gouge after construction to damage the foundation.

Aluminum alloy

1. Function: Aluminum alloy is used as the main inlay and covering support member of the glass greenhouse. Its main functions are: (1) cooperate with rubber seals, as a part of the sealing system of the glass greenhouse cover; (2) use alone, as the greenhouse roof support Components and sealing components; (3) Used as a gutter.

2. Design requirements: The main part mainly meets the requirements of strength and rigidity; the support part is used as the support of the glass to reserve some long support grooves or inlay grooves; the part of the inlay part on the outside of the glass needs to be equipped with special rubber for installation The sealed groove can be used to fix rubber seals, and can also be used with small aluminum alloy or stainless steel parts to fix glass.
