Abstract
The present invention is a kind of method with welding manner connection polyurethane thermal insulation board, and in this method, the one side of two pieces of polyurethane thermal insulation board connecting sewings (4) uses welding manner, and another side is using sealant sealing.The stainless steel plate (8) of V-groove (9) two sides welds together with the steel pipe (7) of lower section, make weld seam and abutment joint (4) not in a vertical plane, form dislocation, the structure of this kind dislocation is easy to operate when on the one hand making to weld, on the other hand since welding region and two pieces of polyurethane thermal insulation board connecting sewings (4) separate and are located on steel pipe (7), the high temperature that welding generates will not ignite polyurethane foam, in addition, V-groove (9) on stainless steel plate (8) has flexible surplus, inner panel (2) deformation that very good solution is fully welded rear polyurethane thermal insulation board causes the disengaging with polyurethane foam.The structure can also effectively meet environmental test chamber's construction requirements, bear quickly temperature and become impact.
Description
Technical field
The present invention is a kind of method with welding manner connection polyurethane thermal insulation board, belongs to the field shaping technique of product.
Background technique
Laboratory and environmental simulation, quick-freezer, special medicine etc., traditional PVC structure, socket connection structure and extension
Hook connects structure has been unable to meet requirement.In this case, the seam of library plate uses and is welded on library sheetmetal panel
Method together is an effectively method.But library plate will appear 2 problems using welding structure: on the one hand welding generates
Localized hyperthermia will cause the burning of polyurethane foam, on the other hand since using being fully welded, plate, which is easily deformed, causes library plate table
The disengaging of face metal plate and polyurethane foam i.e. shelling phenomenon.Due to traditional PVC structure, socket connection structure and hook connection
On the one hand the library plate of 3 kinds of structures of structure can not be fully welded since plate stitch is larger, on the other hand since plate is relatively thin (generally
0.5mm), therefore the library plate of this 3 kinds of structures is not suitable for welding.Welded library plate must carry out new according to weld characteristics
Structure design.
Summary of the invention
The present invention is exactly directed to above-mentioned problems of the prior art and designs to provide and a kind of connected with welding manner
The method of polyurethane thermal insulation board solves sheet deformation and causes library plate table the purpose is to improve the bonding strength of polyurethane thermal insulation board
The localized hyperthermia that the break-off and welding of face metal plate and polyurethane foam generate causes the burning of polyurethane foam.
The purpose of the present invention is achieved through the following technical solutions:
The present invention provides a kind of method with welding manner connection polyurethane thermal insulation board, which includes outer
The inner panel 2 that protection and invigoration effect are played on the outside plate 1 and inner surface played role in decoration on surface, is filled between outside plate 1 and inner panel 2
There is the layer of polyurethane 3 of foaming, it is characterised in that: the step of this method is as follows:
Step 1: in the outside plate 1 of one piece of polyurethane thermal insulation board connecting sewing 4, the inside of inner panel 2 and being machined with item along connecting sewing
Shape boss 5, in the outside plate 1 of another piece of polyurethane thermal insulation board connecting sewing 4, the inside of inner panel 2 and along connecting sewing to be machined with strip recessed
Slot 6, in docking, strip boss 5 and strip groove 6 coincide two pieces of polyurethane thermal insulation board connecting sewings 4；
Step 2: on the strip boss 5 of 2 inside of inner panel of polyurethane thermal insulation board connecting sewing 4 and the side of strip groove 6,
The preset one rectangular steel pipe 7 parallel with strip boss 5 or strip groove 6, steel pipe 7 is located in polyurethane thermal insulation board and top
The flush of the inner panel 2 of end face and polyurethane thermal insulation board；
Step 3: two pieces of polyurethane thermal insulation board connecting sewings 4 are after docking, in the connecting sewing 4 of the outside plate 1 of polyurethane thermal insulation board
Place is sealed with sealant；
Step 4: two pieces of polyurethane thermal insulation board connecting sewings 4 are after docking, in the connecting sewing 4 of the inner panel 2 of polyurethane thermal insulation board
Place covers the stainless steel plate 8 of a strip above along connecting sewing 4, and the center of stainless steel plate 8 is machined with along its length by curved
The V-groove 9 of foldable type, the V-groove 9 are located at the top of connecting sewing 4, then by the steel of the stainless steel plate 8 of 9 two sides of V-groove and lower section
Pipe 7 welds together.
Technical solution of the present invention not only can solve welding generate localized hyperthermia will cause polyurethane foam burning and
Due to causing the break-off of surface metal plate and polyurethane foam using being fully welded polyurethane thermal insulation board and be easily deformed, additionally it is possible to meet
Environmental test chamber's construction requirements bear fast temperature impact.
The connection structure of the two pieces of polyurethane thermal insulation boards designed in technical solution of the present invention is completed in a plug-in manner, should
Structure flexing resistance is strong, and production is simple, and monolithic polyurethane thermal insulation board length longest can reach 20m, and plate and plate bonding strength are big.
The connection structure uses plane-welding mode, plate and plate and weld seam to form a plane.In technical solution of the present invention,
The one side of two pieces of polyurethane thermal insulation board connecting sewings 4 uses welding manner, and another side is sealed using sealant.9 two sides of V-groove are not
Rust steel plate 8 and the steel pipe 7 of lower section weld together, and make weld seam and connecting sewing 4 not in a vertical plane, form dislocation, should
The structure of kind dislocation is easy to operate when on the one hand making to weld, and is on the other hand connect due to welding region with two pieces of polyurethane thermal insulation boards
Seam 4 separates and is located on steel pipe 7, and the high temperature for welding generation will not ignite polyurethane foam, in addition, the V-type on stainless steel plate 8
Slot 9 has a flexible surplus, the inner panel 2 that very good solution is fully welded rear polyurethane thermal insulation board deform cause it is de- with polyurethane foam
From.The structure can also effectively meet environmental test chamber's construction requirements, bear quickly temperature and become impact.
Detailed description of the invention
Fig. 1 is the attachment structure schematic diagram of two pieces of polyurethane thermal insulation boards in the method for the present invention
