[0002] As an important insulation component of the cold storage roof structure, the cold storage ceiling must rely on a large number of ceiling structures to bear the load during the construction process. The traditional cold storage ceiling connection structure is a single-hanging point structure. This single-point connection structure has the disadvantages of insufficient strength, small contact surface of the point of force, poor installation stability, easy damage to the top surface structure, and causing cold leakage. Utility Model Content

[0004] The utility model adopts the following technical scheme: a cold storage ceiling support structure, including a plurality of groups of round steel hangers; one end of the plurality of groups of round steel hangers is connected to the top floor, and the other end is vertically arranged downward and connected to a keel frame support net structure at the end; the keel frame support net structure is formed by a plurality of transverse keels and longitudinal keels arranged in a criss-cross pattern; a ceiling enclosure corrugated board is laid on the bottom of the keel frame support net structure; a polyurethane insulation layer is formed on the top of the ceiling enclosure corrugated board by on-site layered spraying; an inorganic glass fiber reinforced plastic protective layer is scraped on the top of the polyurethane insulation layer; a PVC sleeve is set at the contact between the plurality of groups of round steel hangers and the inorganic glass fiber reinforced plastic protective layer; a polyurethane partition block is formed in the PVC sleeve by on-site spraying of polyurethane.

[0005] Furthermore, a steel mesh layer is embedded in the polyurethane thermal insulation layer.

[0006] Furthermore, the transverse keel frame and the longitudinal keel frame located on the side are bolted to the outer wall through an inverted L-shaped angle steel bracket.

[0007] Furthermore, the spacing between a plurality of the transverse keel frames is 1.2-1.5 m; the spacing between a plurality of the longitudinal keel frames is 1.2-1.5 m.

[0008] Furthermore, the round steel hanger has a height of 1.4-1.6 m and a diameter of 12-15 mm.

[0009] Compared with the prior art, the advantages of the utility model are:

[0010] The cold storage ceiling support structure designed by the utility model is to lay an inorganic fiberglass protective layer on the top of the polyurethane insulation layer to protect the top of the ceiling board, and to form a support net structure at the bottom of the polyurethane insulation layer by using the keel frames arranged vertically and horizontally. At the same time, the ceiling enclosure corrugated board is used to support the bottom of the keel frame to avoid single-point connection damaging the insulation layer board surface structure, thereby improving the ceiling bearing capacity and extending the service life. At the same time, polyurethane is sprayed on the ceiling enclosure corrugated board to form a polyurethane insulation layer structure, and the traditional polyurethane sandwich panel ceiling is changed to the on-site spraying of polyurethane. The overall formed polyurethane layer effectively avoids the formation of gaps and the cold bridge phenomenon. In addition, one end of the side keel of the utility model is fixed to the wall, and the top is fixed to the ceiling color steel plate, so that the entire ceiling color steel plate is firmly connected to the wall, avoiding the up and down shaking caused by the internal and external air pressure difference during the later use of the cold storage, thereby enhancing the integrity and firmness.

DETAILED DESCRIPTION

[0014] In order to facilitate those skilled in the art to understand the technical solution of the utility model, further description is now made with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model.

[0015] In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present invention. However, it is apparent that one or more embodiments may be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0016] Please refer to Figure 1, is a structural schematic diagram of the cold storage ceiling support structure of this embodiment, including several groups of round steel hangers 1, the height of the round steel hangers 1 is 1.4-1.6m, and the diameter is 12-15mm, which is specifically set according to the needs of on-site construction. One end of several groups of round steel hangers 1 is connected to the top floor 2, and the other end is vertically downward and connected to the keel support network structure at the end. The keel support network structure is formed by a plurality of transverse keel frames 3 and longitudinal keel frames 4 arranged in a criss-cross pattern, and the transverse keel frames 3 and longitudinal keel frames 4 located on the side are bolted to the outer wall 12 through an inverted L-shaped angle steel bracket 11. During specific implementation, the spacing between several transverse keel frames 3 is set to 1.2-1.5m, and the spacing between several longitudinal keel frames 4 is set to 1.2-1.5m. The corrugated board 5 for ceiling enclosure is laid at the bottom of the keel support net structure. The top of the corrugated board 5 for ceiling enclosure is sprayed on site to form a polyurethane insulation layer 6. In the specific implementation, during the layered spraying, a steel mesh layer 10 is added to each polyurethane insulation layer to improve the overall stability of the insulation layer. The inorganic fiberglass protective layer 7 is scraped on the top of the polyurethane insulation layer 6. PVC sleeves 8 are set at the contact points between several groups of round steel hangers 1 and the inorganic fiberglass protective layer 7. Polyurethane is sprayed on site inside the PVC sleeves 8 to form polyurethane partition blocks 9, which are used to break the cold bridge treatment at the connection to prevent cold escape.

[0017] The cold storage ceiling support structure designed in this embodiment lays an inorganic fiberglass protective layer on the top of the polyurethane insulation layer to protect the top of the ceiling board, and uses the vertically and horizontally arranged keel frames to form a support network structure at the bottom of the polyurethane insulation layer. At the same time, the bottom of the keel frame is supported by the ceiling enclosure corrugated board to avoid single-point connection damage to the insulation layer board structure, thereby improving the ceiling bearing capacity and extending the service life.

[0018] At the same time, polyurethane is sprayed on site on the corrugated board of the ceiling enclosure to form a polyurethane insulation layer structure. The traditional polyurethane sandwich panel ceiling is changed to the on-site spray polyurethane. The overall polyurethane layer effectively avoids the cold bridge phenomenon caused by gaps. In addition, one end of the side keel of the utility model is fixed to the wall, and the top is fixed to the ceiling color steel plate, so that the entire ceiling color steel plate is firmly connected to the wall, avoiding the up and down shaking caused by the internal and external pressure difference during the later use of the cold storage, and enhancing the integrity and firmness.

[0019] The above embodiments are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
