Optimizing allocation quick fix general-purpose door pocket as well as manufacturing method thereof

Abstract

A universal door pocket and a manufacturing method for optimally recombining and fast installing, a primary board and a secondary board are a piece of integral board respectively. The secondary board is inserted into box-shaped (with opening toward right) slot of the primary board. The inner edge of the groove near the wall extends a length for installing a connecting piece to fix the primary board on the wall body. The primary board close to the door is opened with a rectangular nick. The head faces of the primary and secondary boards are opened with grooves, in which the decorative L-shaped board is. Only one standard of the primary board, II-shaped board or rectangular board and decorative L-shaped board is made in the factory. Various door pockets of wall thickness can be recombined on the spot. And II-shaped door frame and door, push-in door opening, correcting and regulating, drilling and fixing the primary board, nesting and cutting the secondary board, inserting the secondary board, foaming and coating, regulating clearance and blocking the decorative L-shaped board are recombined continuously and finished once. The integrity of the door pocket is strong, and the verticality is regulated easily. In a factory, the primary board is formed by connecting and bonding three small blocks and the secondary board composed of two small rectangular decorative boards and artificial boards. Each small rectangular board is optimal, which saves material and time. The assembly needs no pre-measurement and does not need to install after solidifying the froth rubber in the next day, which realizes high efficiency and fast speed, and fits for various wall thickness and scale manufacturing locations.

Description

(1) Technical field: [0001] The invention relates to an adjustable universal combined door cover adaptable to various wall thicknesses and a manufacturing method thereof, which belongs to the category of closing devices for building openings (E06B). (two) background technology: [0002] In recent years, a large number of finished combination door covers have been sold in the market. The decorative strips, integrated main board and auxiliary board are made in the factory, and then assembled on site. Since the walls of existing buildings have standard and non-standard specifications, and each wall thickness has manufacturing tolerances, in order to adapt to changes in wall thickness, the manufacturer must first go to the site to accurately measure the size and size of the door opening before making the door cover. Corresponding quantity, and then place an order for factory production, the factory produces various main boards of different widths according to various wall thickn...

AI Technical Summary

Problems solved by technology

[0005] The optimized and quick-installed universal door cover and the manufacturing method provided by the present invention are to solve the problem that the existing combination door cover in the market is used for different wall thicknesses, and there are many main board specifications, which cannot be deployed on site, and the production, transportation and installation cycle is long, making it difficult to realize large-scale production and Adapt to international market operation

Solve the many defects of the existing Chinese patent adjustable universal door frame structure: one is poor integrity, complex installation and low efficiency; the other is the decorative L-shaped plate installed at one end of the door, and this structure is difficult to adjust the verticality of the door and other problems
