Wooden stair beam and method for making same

Abstract

The present invention relates to a cross beam and its manufacturing method for wooden stairs, and comprises a cross beam entity, which is provided with a wood strip layer with an interval in the radial direction, a dense wood layer is arranged between two adjacent wood strip layers, wood strip fiber in the wood strip layer and wood block fiber in the dense wood layer are crossed and the manufacturing method includes molding, material taking, solid manufacturing, mold disassembly and sealing procedures. In the procedures of mold manufacturing, according to arc of cross beam of the stair, an upper mold beam and an lower mold beam are arranged, a mold frame is formed between the upper and the lower mold beams through a plurality of vertical connecting beams, the upper end of the mold frame is connected and fixed on the ground; during the procedure of solid manufacturing, wood strips of the outermost wood strip layer are fixed on the mold frame with an interval in the radial direction, and a plurality of wooden blocks are arranged and fixed on the outermost wood strip axially to form a dense wood layer, a wood strip layer is fixed on the dense wood layer, and the wood strip fiber in the wood strip layer and the wood block fiber in the dense wood layer are crossed. Repeat the above procedure until required cross beam width is reached.

Description

Technical field: [0001] The invention relates to a staircase and its manufacturing method, in particular to a wooden staircase beam and its manufacturing method Background technique: [0002] At present, the production of wooden stairs is carried out by hand-made on-site production or factory prefabricated on-site installation. Since the raw wood for making wooden stairs is hard wood, it is difficult to bend and deform, so that the change of the shape of the existing wooden stairs is restricted. , people can only express the change of the stairs through additional parts, or splicing the wood in sections to achieve the purpose of bending changes, but this way causes the appearance of the stair beams to be segmented, the firmness is reduced, it is easy to loose, and it cannot withstand over-stressing. High pressure, poor safety of the stairs, also affects the beauty of the whole stairs, the cost of the stairs is very high. Invention content: [0003] The purpose of the pres...
