Embodiment 1
[0027] The thermal insulation construction method for steel columns in a steel structure cold storage of the present invention comprises the following steps:
[0028] a. After the construction of the cold storage foundation or the concrete structure layer is completed, the upper main steel structure is hoisted. Before the steel structure column 1 insulation construction, the construction of the cold storage wall and roof has been completed; please refer to figure 1 , figure 1 It is a schematic diagram of the thermal insulation structure of the steel structure column in the embodiment of the present invention.
[0029] b. The steel structure column 1 is an H-shaped steel column, and can also be a box-shaped column, a cross column and other materials. After being prefabricated in the structure factory, it is transported to the site for installation; the steel column polyurethane insulation layer 4 has different thickness according to the cold storage refrigeration standards and...

Abstract
A construction method for thermal insulation of steel columns in a steel structure cold storage, which is characterized in that it includes the following steps: a. hoisting the upper main body steel structure after the construction of the cold storage foundation or the concrete structure layer; b. Up to on-site installation, the steel column polyurethane insulation layer (4) is a polyurethane color steel sandwich panel, c, the steel structure column (1) and the cold storage wall board and roof are constructed to form steel column insulation construction conditions, d, in calcium silicate Board (3) outsourcing polyurethane insulation layer (4), e. Polyurethane insulation layer (4) to the suspended ceiling is always covered with color steel plate inner corners; use the same steps above to complete all steel structure columns (1) polyurethane insulation construction. The invention has the advantages of convenient procurement and construction of materials, high construction efficiency, reliable quality, isolation of cold bridges, good isolation of steel structure columns and cold storage, avoiding waste of cold sources, reducing enclosure costs, convenient construction of components on site and ensuring construction safety The advantages.
Description
technical field [0001] The invention relates to a construction method for thermal insulation of a cold storage, in particular to a construction method for thermal insulation of a steel column in a cold storage with a steel structure. Background technique [0002] In recent years, with the increasing demand of Chinese consumers for fresh food, the freshness of food is more valued, and people's consumption of cold chain food is gradually increasing, which brings greater development space for the food cold chain logistics industry , Cold chain logistics has also entered people's daily life. The increase in demand for cold chain food, mainly meat products, quick-frozen products and dairy products, marks people's pursuit and yearning for a high-quality life, which also provides a huge market space for cold chain logistics. [0003] The cold storage with steel structure as the main body is widely used in large and medium-sized cold storage due to the advantages of high steel stru...
