Abstract
The utility model discloses a polyurethane sandwich lamina joint which comprises a convex plate and a concave plate. The outer layers of the convex plate and the concave plate are metal boards, and the convex plate and the concave plate are filled with foaming polyurethane inside. The width of the front end at the head of the convex plate is more than the width of the back end, and the front end is provided with an outer circular bead. The width of a front port of a groove of the concave plate is less than the width of a back port, and the front port is provided with an inner circular bead. The polyurethane sandwich lamina joint has the advantages of reasonable structure, good connection strength, obvious heat insulation and heat preservation effects etc.
Description
Technical field
The utility model relates to a kind of New Building Materials, and is especially relevant with the polyurethane laminboard joint.
Background technology
It is single lenticular that existing polyurethane laminboard joint is generally, and exists deficiencies such as bonding strength is low, heat insulation and preservation effect difference.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, and bonding strength is good, the significant polyurethane sandwich thin plate of heat insulation and preservation effect joint.
For achieving the above object, the utility model is achieved through the following technical solutions.Polyurethane sandwich thin plate joint, comprise flange and notch board, the skin of flange and notch board is a sheet metal, in fill polyurathamc, the width of the front end of the head of flange is greater than the width of rear end, and the front end place is provided with the Wai Yuan angle, and the width of the front port of the groove of notch board is less than the width of rear port, and the front port place is provided with the Nei Yuan angle.
Described polyurethane sandwich thin plate joint, the sheet metal of the front end of the head of its flange is provided with the garden arc and colludes, and the sheet metal at the rear port place of the groove of notch board is made as notch cuttype.
Described polyurethane sandwich thin plate joint, the rear port place of the groove of its notch board is provided with the layer of polyurethane that exposes to sheet metal.
The utility model compared with prior art has following advantage: (one) be since the width of flange head front end greater than the width of rear end, and the front end place is provided with the Wai Yuan angle, the width of notch board groove front port is less than the width of rear port, and the front port place is provided with the Nei Yuan angle, not only connect easy and conveniently, and bonding strength is good; (2) be that the sheet metal at notch board groove rear port place is made as notch cuttype, has increased the contact area of sheet metal and polyurethane owing to be provided with the garden arc at the sheet metal of flange head front end and collude, thus the bond strength when having improved foaming; (3) be owing to be provided with the layer of polyurethane that exposes to sheet metal, flange is closely contacted with notch board, improve heat insulation effect at notch board groove rear port place.
