Description

Integrally formed decoration strip component for flat frame glass fiber reinforced plastic door

Technical Field

The invention relates to the technical field of building industry, in particular to an integrally formed decoration strip component for an integrated flat-frame glass fiber reinforced plastic door, which is favorable for improving the production efficiency and the appearance quality of the product.

Background

The glass is installed on the glass-reinforced plastic door by cutting a glass opening on the glass-reinforced plastic door and then installing the glass with a plastic frame at the glass opening, wherein the plastic frame protrudes out of the surface of the glass-reinforced plastic door. The traditional glass fiber reinforced plastic door wastes materials, has high cost, is easy to age and lose efficacy, has poor sealing performance and has a squat and unattractive appearance. The novel flat-frame glass fiber reinforced plastic door is characterized in that glass is directly installed on the door in the process of producing the door, and a glass pressing strip is integrated with a door skin and is flush with the surface of the door skin. The flat-frame glass fiber reinforced plastic door has the advantages of low production cost, excellent sealing performance, long service life, concise and beautiful appearance and the like, and is widely applied to the entrance doors of foreign villa buildings. The decorative glass with the largest usage amount is formed by manually pasting decorative strips on the inner and outer surfaces of the hollow glass of the flat-frame glass reinforced plastic door to simulate the style of the traditional French-style wooden door. The decorative strip used in the current market is an extruded low-foaming plastic section, the bottom surface of the section is provided with a double-sided adhesive tape, and the incoming material is in a fixed length. The method for producing the flat-frame glass fiber reinforced plastic door decorating strip by using the section bar comprises the following steps: the method comprises the steps of cutting incoming materials into required lengths, processing the end parts of the incoming materials into special shapes according to the curved surface shape of a glass pressing strip of the flat-frame door, and adhering each independent decorative strip to the inner surface and the outer surface of the hollow glass of the flat-frame glass fiber reinforced plastic door completely by manpower to form a required pattern. The method for manually bonding each independent decorative strip on the inner surface and the outer surface of the hollow glass of the flat-frame glass reinforced plastic door mainly has two defects: firstly, the decoration strips need to be secondarily processed on site and each independent decoration strip needs to be manually adhered to the surface of the glass, so that the efficiency is low, the time consumption is long, and the labor cost is high. Secondly, the connecting part of the horizontal and vertical decorating strips is provided with a gap, which causes the appearance to be unattractive.

Methods of bonding trim beads to glazing are described in U.S. Pat. Nos. 4,598,520A, 6,898,914 A1 and 4,783,938A. In patent US 4,598,520A, the applicant disclosed a method for gluing, on the internal and external surfaces of the hollow glass of a door, a wooden decorative strip consisting of a plurality of separate strips crossing horizontally and vertically. In the patent US 6,898,914 A1, the applicant disclosed a method of adhering intersecting horizontal and vertical decorative strips to a glazing surface, wherein one strip must be continuous and the remainder broken, and then adhering the separate strips to the glazing surface. In patent US 4,783,938A, the applicant disclosed a window design with a metal inner pane and a wood outer pane, wherein the metal inner pane intersecting in the vertical and horizontal direction is placed between 2 sheets of glass, and then a prefabricated wood outer pane also intersecting in the vertical and horizontal direction is manually glued to the surface of the hollow glass in the position corresponding to the metal inner pane. .

The core of all the disclosed production methods is however the manual gluing of individual cut-to-length decorative strips to the glass surface.
