Manufacture method of arc rotary solid-wood stair beam

Abstract

The invention relates to a preparation method used for an arc-shaped rotary solid wood stair beam, comprising the steps as follows: preparing solid wood small billets, secondary drying, colour separating and material selecting, material cutting, finger jointing, four-surface plane forming, thin sheet cutting, plate assembling, precise saw width-fixing, sanding thickness-fixing, explosive-proof trough cutting on single plate, assembling and forming; the assembling and forming comprise the steps as follows: 1: a die is firstly adjusted; 2: step (height and width of step) of the stair is determined; 3: the single plate is fixed; 4: when the layer number required by the stair and the thickness of the beam are achieved, the die is locked and pressurized. The stairs produced according to the invention have good stability and no rebounce, are not easy to deform, have smooth and graceful whole lines meeting the requirement of decoration, have high bearing strength, are firm and reliable, have strong impact force resistance, ensure the safety, have high preciseness of the ladder radian, can be adjusted according to the requirement, can be produced industrially and have quick effect.

Description

technical field [0001] The invention relates to a spiral staircase, in particular to a method for manufacturing an arc-shaped curved beam of the spiral staircase. Background technique [0002] With the great improvement of people's living standards and the improvement of the living environment, some families have been able to purchase villas or duplex buildings. The upper and lower floors of this kind of building must be connected by stairs, and the spiral staircase with beautiful form It won the favor of people. At present, domestic stair manufacturers can say that there are various techniques for producing curved solid wood stair beams. It can be said that they have invested a lot of manpower, material resources, and financial resources to improve and update the production process, and they all claim that their technological level is first. First-class, but due to the relative lag of the industry standard, it is still in the groping stage for various manufacturers. It is ...
