Problems solved by technology

[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, which restricts the change of the shape of the existing wooden stairs. , 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, the safety of the stairs is poor, and it also affects the beauty of the entire staircase, and the cost of the stairs is very high

Embodiment Construction

[0022] As shown in Fig. 1-4, a kind of wooden stair crossbeam of the present invention, it comprises crossbeam entity, and beam entity is arranged with wooden lath layer 3 at intervals in warp direction, and is provided with wood block dense layer between two adjacent wooden lath layers 2. The fibers of the slats in the slat layer and the fibers of the blocks in the dense layer of wood blocks are intersected in space. The wooden slat layer of the beam entity is composed of at least one wooden slat, and may also be composed of multiple slats. The wood block dense layer 2 of the beam entity is formed by a plurality of wood blocks 5 densely arranged in the weft direction. The wooden lath layer of the beam entity and the dense layer of wood blocks are connected as a whole through connectors and adhesives. The outer surface of the beam entity is covered with upper and lower sealing plates 4 and side sealing plates 1 . The manufacture method of the wooden stair beam of the present...

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 a manufacturing method thereof, in particular to a wooden staircase beam and a manufacturing method thereof. 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, which restricts the change of the shape of the existing wooden stairs. , 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 t...
