Description
Technical field
The present invention is a kind of method that polyurethane thermal insulation board is connected with welding manner, belongs to the field shaping technique of product.
Background technology
Laboratory and environmental simulation, quick-freezer, special medicine etc., traditional PVC structures, socket connection structure and extension
Hook connects structure can not meet requirement.In this case, the seam of storehouse plate uses and is welded on storehouse sheetmetal panel
Method together is an effectively method.But 2 problems occur using welding structure in storehouse plate：On the one hand welding produces
Localized hyperthermia can cause the burning of polyurethane foam, on the other hand cause storehouse plate table because using full weld, sheet material is easily deformed
The disengaging of face metal plate and polyurethane foam i.e. shelling phenomenon.Due to traditional PVC structures, socket connection structure and hook connection
The storehouse plate of 3 kinds of structures of structure on the one hand due to plate stitch it is larger can not full weld, on the other hand because sheet material is relatively thin (generally
0.5mm), therefore the storehouse plate of this 3 kinds of structures is not suitable for welding.Welded storehouse plate must carry out new according to weld characteristicses
Structure design.
The content of the invention
The present invention is exactly to provide a kind of to be connected with welding manner for above-mentioned problems of the prior art and designing
The method of polyurethane thermal insulation board, the purpose is to improve the bonding strength of polyurethane thermal insulation board, solve sheet deformation and cause storehouse plate table
Localized hyperthermia caused by the break-off and welding of face metal plate and polyurethane foam causes the burning of polyurethane foam.
The purpose of the present invention is achieved through the following technical solutions：
The invention provides a kind of method that polyurethane thermal insulation board is connected with welding manner, the polyurethane thermal insulation board includes outer
The inner panel (2) of protection and invigoration effect, outside plate (1) and inner panel (2) are played on the outside plate (1) and inner surface played role in decoration on surface
Between filled with foaming layer of polyurethane (3), it is characterised in that：The step of this method, is as follows：
Step 1: the inner side of outside plate (1), inner panel (2) in one piece of polyurethane thermal insulation board connecting sewing (4) and adding along connecting sewing
Work has strip boss (5), the inner side of outside plate (1), inner panel (2) in another piece of polyurethane thermal insulation board connecting sewing (4) and along connection
Seam is machined with strip groove (6), and two pieces of polyurethane thermal insulation board connecting sewings (4) are in docking, strip boss (5) and strip groove
(6) it coincide；
Step 2: strip boss (5) and strip groove (6) on the inside of the inner panel (2) of polyurethane thermal insulation board connecting sewing (4)
Side, preset one rectangle or square steel pipe (7) parallel with strip boss (5) or strip groove (6), steel pipe (7) position
In in polyurethane thermal insulation board and the inner panel of top end face and polyurethane thermal insulation board (2) flush；
Step 3: two pieces of polyurethane thermal insulation board connecting sewings (4) are after docking, in pair of the outside plate (1) of polyurethane thermal insulation board
Seam (4) place sealant sealing；
Step 4: two pieces of polyurethane thermal insulation board connecting sewings (4) are after docking, in pair of the inner panel (2) of polyurethane thermal insulation board
Seam (4) place, along abutment joint (4) stainless steel plate (8) of a strip is covered above, stainless steel plate (8) centrally along length side
To the V-groove (9) being machined with by bending forming, the V-groove (9) is located at the top of abutment joint (4), then by V-groove (9) both sides
Stainless steel plate (8) and the steel pipe (7) of lower section weld together.
Technical solution of the present invention can not only solve to weld caused by localized hyperthermia can cause polyurethane foam burning and
The break-off of surface metal plate and polyurethane foam is caused due to being easily deformed using full weld polyurethane thermal insulation board, additionally it is possible to meet
Environmental test chamber's construction requirements, bear fast temperature impact.
The attachment structure of the two pieces of polyurethane thermal insulation boards designed in technical solution of the present invention is completed with inserting mode, should
Structure flexing resistance is strong, makes simply, monolithic polyurethane thermal insulation board length is most long to can reach 20m, and plate and plate bonding strength are big.
The attachment structure uses plane-welding mode, and plate forms a plane with plate and weld seam.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 uses sealant sealing.V-groove (9) both sides
Stainless steel plate (8) and the steel pipe (7) of lower section weld together, make weld seam and abutment joint (4) not in a vertical plane, shape
Into dislocation, the structure of this kind dislocation is easy to operate when on the one hand making welding, on the other hand due to welding region and two blocks of polyurethane
Warming plate connecting sewing (4) separates and on the steel pipe (7), and high temperature caused by welding will not ignite polyurethane foam, in addition, not
The V-groove (9) to become rusty on steel plate (8) has flexible surplus, solves inner panel (2) deformation of polyurethane thermal insulation board after full weld well
Cause the disengaging with polyurethane foam.The structure can also effectively meet environmental test chamber's construction requirements, bear quick temperature and become impact.
