After surface cleaning and concave-convex structure removing operations are conducted on a base wall body, the base wall body is clung to the surface of the horizontal plane body, so as to form a leveling layer; one to five layers of closed air separation layers adopting the structures with PE (Poly Ethylene) films or metal foil films are laid on the outer side surface of the leveling layer; one to six layers of extruded sheets with staggered joint structures are fixedly laid on the outer side surfaces of the air separation layers respectively through riveting or bonding; no gap is formed between the extruded sheets in the transversal direction; the bound edges are not overlapped; an outer decorative layer is arranged on the outer side surface of each extruded sheet; the beginning ends of all the extruded sheets are aligned with each other, and are in sealed butt joint with each other at the bent part of each surface of the inner casing; the bent parts or the corners of the outer decorative layers are in sealed butt joint with each other; the extruded sheets are fixedly laid through expansion blots made of stainless materials; the extruded sheet on the outermost layer is fixed through a self-drilling nail; the horizontal plane body adopts the structure that a steel keel or a grid is additionally arranged in the outer decorative layer of the ceiling surface; and a marble or concrete structure is laid in the outer decorative layer of the bottom surface. As the integral structure of the horizontal plane body is simple, and the butting performance and the leak tightness of plates are good, the raw material and the energy are saved. Therefore, the inner casing is suitable for ceilings and bottom surfaces of heat-insulating warehouses adopting box-type or warehouse-type structures in various heat-insulating occasions.

Description

The board-like heat room inner housing of a kind of extrusion molding horizontal plane body

Technical field:

The utility model belongs to the heat room equipment technical field, relates to a kind of employing extruded sheet splicing structure formula and makes up heat room inner housing, the board-like heat room inner housing of particularly a kind of extrusion molding horizontal plane body.

Background technology:

At present; Employed refrigeration being arranged, heating heat-preserving equipment all is to adopt air partition-type heat preserving mode, and the structure of its heat-preserving equipment generally is divided into shell body and inner housing two large divisions, and shell body is born to reinforce with support function is double and is incubated; And inner housing carries main heat insulation function owing to directly contacting warm source; Freezer is a kind of as heat room, and according to statistics, the power consumption of space enclosing structure or inner housing accounts for about 30% of whole freezer in the freezer; Therefore, the choice relation of the heat insulating material of space enclosing structure or inner housing is to the energy consumption of whole freezer.Existing extruded sheet hexahedron heat-insulation system or title extruded sheet are heat insulating materials (XPS) special-purpose in the freezer space enclosing structure; Can satisfy the requirement of heat insulating material different-thickness in the Refrigerating House Design; Especially can demonstrate fully its outstanding heat-insulating property and energy-saving effect in some low temperature storehouses and quick freezing repository, product is used for low temperature storehouse, quick freezing repository, constant heat storage, high temperature storehouse and various large, medium and small freezer.The heat insulating material of heat room structure use is divided into PU foaming type and extrusion moulding type warming plate usually at present; The structure of PU foaming type warming plate is to be that primary raw material and toluene di-isocyanate(TDI) (TDI) or diphenylmethane diisocyanate fat (MDI) or the different sour fat of polymethine polyphenylene (PA-PI) add blowing agent, catalyzer, foam stabiliser etc. by a certain percentage with mylar or polyethers resin; Under suitable temperature, stir the made foamed plastics that foams through mixing and be polyurethane foam plastics; The structure that plastic extrusion heated board is called for short extruded sheet is with this hard heat-insulated heat-barrier material of extruded polystyrene warming plate; Sheet material by polystyrene resin and other additive extrusion modling; The process of its extruding produces and has continuously the sheet material of epidermis and closed pore formula honeycomb structure uniformly; The interconnect walls of these honeycomb structures is by the thickness of unanimity; The space can not occur, so the uniform formation that forms of extrusion process makes product have superior thermal and insulating performance, good moisture-resistant humidity resistance and high compressive property; Because production technology and material, extruded sheet has light weight, intensity is high, water absorption rate is low, acid and alkali-resistance, heat insulation, sound insulation, good heat preservation performance, shockproof, easy-formation, not by advantages such as biology decomposition, be the preferred material of present heat room heat insulating material.When existing heat insulating material prepares the inner housing of heat room; The structure of its construction technology and formation has nothing in common with each other, and the drawback of existence is that construction technology is complicated, and difficulty of construction is big; Materials are many; Particularly sheet material docks and curves the construction poor sealing at place, and its overall heat insulating ability is difficult to reach the requirement of technical indicator, causes the waste of the energy.

Summary of the invention:

The goal of the invention of the utility model is to overcome the shortcoming that existing heat room inner housing technology exists; It is simple to seek to design a kind of construction technological process, controls flexibly, and sealed butt joint is effective; Save the raw material and the energy; Good heat preservation performance, the heat room inner housing horizontal plane body that accommodation is big, the horizontal plane body of this inner housing comprises ceiling face body and round floor body.

To achieve these goals, the agent structure of the utility model comprises basic unit's body of wall, leveling layer, vapour barrier, extruded sheet, outside finish, steel joist, extruded sheet side and extruded sheet initiating terminal; Basic unit's body of wall is being close to surface formation leveling layer after surface clean and removal concaveconvex structure are handled; Be equipped with the closed vapour barrier of 1-5 layer PE membrane structure or metal foil film structure at the leveling layer outer surface; Vapour barrier lateral surface rivet type is respectively fixed or adhesive type technology is laid the 1-6 layer extruded sheet of fissure of displacement structure; Extruded sheet and mould between the plate laterally no gap, zero lap between the tape edge is shaped on the exterior trim layer on the extruded sheet lateral surface; The alignment of the initiating terminal of every layer of extruded sheet, initiating terminal and initiating terminal inner housing each the bending place, side is sealed docks; The sealed butt joint of the bending place of outside finish or corner; The laying of extruded sheet adopts stainless material expandable nail to fix, and the outermost layer extruded sheet adopts the nail of brill certainly of nonmetals fixing; The horizontal plane body is in the exterior trim layer of ceiling face or adds steel joist, or adopts grid structure; The horizontal plane body is that the exterior trim layer of bottom surface adopts laying marble or concrete structure.

The extruded sheet good heat insulating that the utility model is used, endurance quality is strong, and anti-outlet capacity is good; Anti-pressure ability is high, and resistance to freezing and thawing is excellent, belongs to the low-carbon type environment-friendly materials; The overall structure of its horizontal plane body is simple; Panel material butt joint and good airproof performance are saved the raw material and the energy, are applicable to the ceiling and the bottom surface in the formula structural thermal insulation storehouse, case storehouse of all kinds of insulation occasions.
