Abstract
The utility model relates to a building material and provides a polyurethane sandwich board for a cold storage, which is simple in structure, stable in performance, long in service life and easy to popularize and apply on a large scale. The polyurethane sandwich board comprises a board body; the board body is composed of two color steel plates and a polyurethane sandwich board part arranged between the two color steel plates; the color steel plates are bonded with the polyurethane sandwich board part through binding agent layers; a wedge-shaped groove and two small grooves are arranged at one side edge of the board body; the wedge-shaped groove is arranged between the two small grooves; and the other side edge opposite to the side edge of the board body is provided in parallel with small lug bosses which are matched with the small grooves.
Description
Technical field
The utility model belongs to constructional materials, and what be specifically related to is a kind of polyurethane freezer sandwiched plate.
Background technology
Existing freezer sandwiched plate has polyurethane sheet, calcium silicate board with microporous, foam glass board, rock cotton board and EPS plate, its weak point: the density of calcium silicate board with microporous, foam glass board, rock cotton board is big, and coefficient of thermal conductivity is big; Though the EPS plate is in light weight, coefficient of thermal conductivity is big, does not reach the purpose of effectively insulating insulation, and energy-saving effect is undesirable.In addition, the sheet material that is used for freezer is polyurethane sheet mostly, and polyurethane sheet generally adopts box and pin or eccentric hook and snap close overlap joint; The back is filling with sealant at the place, slit, and this structure is when temperature of ice house is low, because fluid sealant and polyurethane are foreign peoples's material; The shrinkage ratio there are differences; Cause between freezer plate plate poorly sealedly, heat insulation effect reduces, thus the waste resource.
The utility model content
The purpose of the utility model is in order to overcome above deficiency, a kind of polyurethane freezer sandwiched plate to be provided, and it is simple in structure, stable performance, and long service life is easy to large-scale promotion application.
The purpose of the utility model realizes as follows: polyurethane freezer sandwiched plate; Comprise plate body; Said plate body is made up of two color steels and the polyurethane laminboard be located between two color steels, and said color steel and polyurethane laminboard are bonding through adhesive phase, and said plate body side is provided with wedge-shaped impression and two little grooves; Said wedge-shaped impression between two little grooves, the parallel small boss that matches with little groove that is provided with of the opposite side of said plate body side.
What further, said wedge-shaped impression can be in polygon groove, conical socket, the isosceles trapezoid groove is a kind of.
The beneficial effect of the utility model is: the utility model is used for construction work, the light weight of polyurethane laminboard, and coefficient of thermal conductivity is little, and chemical property is stable. the design of both sides boss and groove; Make it be suitable for interconnecting each other, form continuous structure, install easily; Good sealing effect can reach the very low refrigerator insulation requirement of temperature requirement, reasonable in design; The novelty that is skillfully constructed, cost of manufacture is low, is easy to large-scale promotion application.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Combine the accompanying drawing and the specific embodiment that the utility model is further specified at present.
Referring to Fig. 1; The polyurethane freezer sandwiched plate of the utility model comprises plate body 1, and said plate body 1 is made up of two color steels 2 and the polyurethane laminboard 3 be located between two color steels 2; Said color steel 2 is bonding through adhesive phase 4 with polyurethane laminboard 3; Said plate body 1 side is provided with wedge-shaped impression 11 and two little grooves 12, said wedge-shaped impression 11 between two little grooves 12, the parallel small boss 13 that matches with little groove that is provided with of the opposite side of said plate body 1 side.Described wedge-shaped impression 11 can be in polygon groove, conical socket, the isosceles trapezoid groove a kind of.During two boards body 1 overlap joint, little groove 12 cooperates grafting with small boss 13, and the middle cavity that forms is injecting liquid polyurethane in cavity, treats after overexpansion, cooling, to solidify, and makes the better tightness of plate body 1.Polyurethane laminboard 6 forms the heat-insulation and heat-preservation structure with color steel 2, both can stop the importing of outside heat, can stop internal temperature externally to conduct again.The light weight of polyurethane laminboard 3, coefficient of thermal conductivity is little, and chemical property is stable. the design of both sides small boss 13 and little groove 12; Make it be suitable for interconnecting each other, form continuous structure, install easily; Good sealing effect can reach the very low refrigerator insulation requirement of temperature requirement, reasonable in design; The novelty that is skillfully constructed, cost of manufacture is low, is easy to large-scale promotion application.
Claims (2)
1. polyurethane freezer sandwiched plate; Comprise plate body; Said plate body is made up of two color steels and the polyurethane laminboard be located between two color steels, it is characterized in that: said color steel and polyurethane laminboard are bonding through adhesive phase, and said plate body side is provided with wedge-shaped impression and two little grooves; Said wedge-shaped impression between two little grooves, the parallel small boss that matches with little groove that is provided with of the opposite side of said plate body side.
2. the polyurethane freezer sandwiched plate of telling according to claim 1 is characterized in that: what said wedge-shaped impression can be in polygon groove, conical socket, the isosceles trapezoid groove is a kind of.
