Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cold storage, in particular to a cold storage partition wall panel bottom breaking cold bridge structure. Background Art
[0002] Cold storage partition walls are important insulation components of the cold storage roof structure. If the sealing treatment of the nodes at the bottom of the partition boards is not done properly, it is very easy to cause cold air to escape, resulting in the failure of cold storage insulation. The existing insulation of the bottom of the partition boards usually adopts the method of directly laying extruded boards close to the storage boards to form an insulation layer. This insulation layer is prone to gaps and has poor insulation effect. Utility Model Content

[0004] The utility model adopts the following technical scheme: a cold storage partition wall panel bottom cold bridge structure, comprising a polyurethane partition wall panel, wherein right-angle steel keels are set on both end surfaces of the bottom of the polyurethane partition wall panel, and are vertically fixed to the ground base surface by steel nails; a moisture-proof and vapor-proof layer is laid between the right-angle steel keel and the ground base surface; a plurality of layers of extruded boards are laid in parallel on the moisture-proof and vapor-proof layer away from both ends of the polyurethane partition wall panel to form an extruded board insulation layer; a plurality of layers of extruded boards are laid with staggered seams; a stepped contact slope is formed at one end of the extruded board insulation layer close to the partition wall panel; a polyurethane cold bridge layer is formed between the two ends of the moisture-proof and vapor-proof layer close to the polyurethane partition wall panel and the contact slope by on-site spraying and foaming; the top surface of the polyurethane cold bridge layer is flush with the extruded board insulation layer, and a waterproof layer and a cement mortar leveling layer are laid in sequence on its upper end; a reinforced concrete surface layer is laid on the upper surface of the cement mortar leveling layer.
[0005] Furthermore, the reinforced concrete surface layer and the contact surface of the polyurethane partition wall panel are vertically and tightly attached to form a vertical supporting surface.
[0006] Furthermore, an inclined sliding surface is arranged on the top of the vertical supporting surface.
[0007] Furthermore, the thickness of the extruded board insulation layer ranges from 100 to 250 mm.
[0008] Furthermore, the thickness of the reinforced concrete surface layer ranges from 120 to 160 mm.
[0009] Compared with the prior art, the advantages of the utility model are:
[0010] The utility model designs a cold storage partition wall panel bottom cold bridge structure. The partition wall panel is vertically erected on the ground base through a right-angle steel keel, and a moisture-proof vapor barrier layer is laid on the ground base for moisture-proof treatment. Several layers of staggered extruded boards are laid in parallel at both ends away from the polyurethane partition wall panel to form an extruded board insulation layer, and the extruded board insulation layer forms a stepped contact slope near one end of the partition wall panel. A polyurethane cold bridge layer is formed between the contact slope and the partition wall panel through on-site spraying and foaming. The staggered paving extends the transmission path of the cold air, and the contact slope further increases the contact area between the cold air and the extruded board insulation layer, avoiding the cold air directly overflowing and causing the cold to escape, thereby improving the insulation effect.

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, which is a schematic diagram of the overall structure of a cold storage partition wall panel bottom cold bridge breaking structure of this embodiment, including a polyurethane partition wall panel 1, and right-angle steel keels 3 are set on both end surfaces of the bottom of the polyurethane partition wall panel 1, and are vertically fixed on the ground base surface 4 by steel nails to form a stable support. During the specific implementation, it is necessary to cut off the metal outer skin of the bottom section of the polyurethane partition wall panel 1 that contacts the bottom surface to prevent the iron sheet at the bottom of the panel from conducting cold, thereby preventing the formation of cold bridges. A moisture-proof vapor barrier layer 5 is laid between the right-angle steel keel 3 and the ground base surface 4 to prevent water vapor from the ground base surface from penetrating into the panel. The moisture-proof vapor barrier layer 5 generally uses SBS waterproof material. Several layers of extruded board are laid in parallel on the moisture-proof vapor barrier layer 5 away from the two ends of the polyurethane partition wall panel 1 to form an extruded board insulation layer 6, and the thickness of the extruded board insulation layer 6 ranges from 100-250mm. Several layers of extruded boards are laid with staggered joints, and the extruded board insulation layer 6 forms a stepped contact slope 7 near one end of the partition wall panel 1. The moisture-proof and vapor-proof layer 5 forms a polyurethane thermal insulation bridge layer 8 between the two ends of the polyurethane partition wall panel 1 and the contact slope 7 by spraying and foaming on site. The top surface of the polyurethane thermal insulation bridge layer 8 is flush with the extruded board insulation layer 6, and a waterproof layer 9 and a cement mortar leveling layer 10 are laid on the upper end in sequence, and a reinforced concrete surface layer 11 is laid on the upper surface of the cement mortar leveling layer 10, and the thickness of the reinforced concrete surface layer 11 ranges from 120 to 160 mm.
[0017] Therefore, the cold storage partition wall panel bottom cold bridge structure designed in this embodiment is vertically erected on the ground base through right-angle steel keels, and a moisture-proof vapor barrier layer is laid on the ground base for moisture-proof treatment. Several layers of staggered extruded boards are laid in parallel at both ends away from the polyurethane partition wall panel to form an extruded board insulation layer, and the extruded board insulation layer forms a stepped contact slope near one end of the partition wall panel. A polyurethane cold bridge layer is formed between the contact slope and the partition wall panel through on-site spraying and foaming. The staggered paving extends the transmission path of the cold air, and the contact slope further increases the contact area between the cold air and the extruded board insulation layer, avoiding the phenomenon of cold air directly overflowing and running away, thereby improving the insulation effect.
[0018] In this embodiment, the contact surface of the reinforced concrete surface layer 11 and the polyurethane partition wall panel 1 are vertically and tightly attached to form a vertical supporting surface 12 for supporting the polyurethane partition wall panel.
[0019] An inclined sliding surface 2 is arranged on the top of the vertical supporting surface 12, and the condensed water formed on the polyurethane partition wall panel 1 can slide along the inclined sliding surface to the reinforced concrete surface layer 11, thereby preventing the condensed water from directly penetrating into the bottom insulation layer through the gap.
[0020] 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.
