Benefits of technology
The present invention is a new type of refrigerated storage that has a special wall structure that brings many benefits. It is built using a quick spraying construction method, which provides better insulation and energy savings compared to combined storage. The construction period is only half that of a civil storage. The wall is made of color steel plates, stainless steel plates, or aluminum plates, which improve fire prevention and collision avoidance. The wall is seamless and has good insulation, making it as safe and reliable as a civil storage. The light steel structure avoids the“cold running” problem, which prolongs the age of the storage.
Problems solved by technology
Though the first type of the refrigerated storage aforementioned has a good sealing and thermal insulation, it takes a long construction period, and thus cost too much and is not flexible enough; the second type of the refrigerated storage takes a short construction period, but it is easy to produce a crack on the joint of the library boards in a long-term process of temperature variation, and this “cold running” problem is particularly serious in a large-sized refrigerated storage with vast proportions; in order to construct this refrigerated storage with a steel frame structure e of the third type aforementioned, it is the most important to dealt with the problem of the broken cold-bridge components inside and / or outside the wall structure and make sure of the Integration and the sealing of the insulation.

Embodiment Construction
[0036]Various preferred embodiments of the invention will now be described with reference to the figures, wherein like reference numerals designate similar parts throughout the various views.
[0037]FIGS. 1-3 illustrate an embodiment of a wall structure of a large-sized refrigerated storage according to the present invention. Referring to FIGS. 1-3, the wall structure of a large-sized refrigerated storage comprises an interior wall color steel plate 1 as an interior wall board, an exterior wall color steel plate 2 as an exterior wall board and a skeleton positioned between the interior wall color steel plate 1 and the exterior wall color steel plate 2. A space formed between the interior wall color steel plate I and the exterior wall color steel plate 2 is filled with polyurethane foam plastic 7. The skeleton is constructed by vertical fixed steel columns 6 and lateral fixed angle steels 5. The vertical fixed steel columns 6 of the skeleton are C-shaped steels which situated at the ex...

A method for constructing a wall structure, which comprises an interior wall board, an exterior wall board and a skeleton positioned between the interior wall board and the exterior wall board. The method for construction the wall comprises the following steps: A. building the wall skeleton; B. mounting a color steel plate on the outer surface of the skeleton to form an exterior wall board of the wall; C. painting the polyurethane spraying material on the exterior wall board layer by layer for multiple times, and reserving a pouring apace at a distance of 40 to 80 mm from the installation position of a interior wall board; and D. taking the color steel plate of the interior wall as a mould plate and pouring space at the color steel plate of the interior wall to form the interior wall board of the wall.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a divisional of U.S. Application Ser. No. 13 / 262,242 filed on Sep. 30, 2011, which application is a national phase entry under 35 U.S.C. §371 of International Application No. PCT / CN2010 / 071436 and filed Mar. 30, 2010, which claims priority from CN 200910038383.0 filed Apr. 3, 2009, all of which are hereby incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to building structure and construction, and more particularly, to a wall structure of a large-sized refrigerated storage and a construction method thereof.BACKGROUND OF THE INVENTION[0003]Currently, the wall construction of large-sized refrigerated storage can be divided into three types: the first kind is a refrigerated storage of Reinforced Concrete Frame Structure by applying the insulation to the outside and / or the inside of the reinforced concrete frame being erected; the second kind is a combined refrigerated storag...
