Abstract

The utility model provides a wooden cambered shaped profile, which belongs to the wooden shaped profile technology of the constructional profile technology field. The common method of producing the special profile cambered shaped profile needs massive wooden boards no matter the suit cutting, or the transfiguration after whole board boiling and pressing. A substitute product and technology are badly needed to meet the requirements of balancing the conflict between the sharp increased requirement of the wooden furniture and the slap-up decoration caused by the per capita consumption in China, thus reducing the tree chopping and protecting the ecologic environment. The utility model provides a technical proposal of splicing the wooden cambered shaped profile by adopting the off cut material of the processed timber. The wooden cambered shaped profile is formed by scheduled amount cutting prisms which are spliced together through the longitude or the latitude line section of the cambered buckling point of the wooden cambered shaped profile, wherein, the symmetric center line of the tenon of the splicing surface of the cutting prism parallels with the splicing surface, and the other symmetric center line is perpendicular to the splicing surface.

Description

Wooden curved section bar

Technical field

The novel wooden curved section bar that provides of this usefulness belongs to the wooden profile material technology in the building material technical field.

Background technology

Abnormal curved surface because changeableization of body has certain dynamic effect again, is used in wood furniture or wooden decorative thing widely.But no matter the method for making abnormal curved surface section bar commonly used cuts out a piece of cloth in a way with the minimum material to make two or more articles of clothing, or after the whole plate boiling, the back distortion of exerting pressure, what need all is the plank material of bulk.This utilization rate is low, requires the technology of becoming a useful person of large-sized rickers again, cost height not only, and especially make every effort to improve the human settlement with China, the state basic policy that reduces the forest-tree felling is not inconsistent.How balance because of the growth of China's pre-capita consumption to wood furniture and the high-grade demand that sharply increases of decorating, and reduce trees felling, conflicting of preserving the ecological environment, is badly in need of a kind of substitute products and the technology appearance that can satisfy two sides requirement simultaneously.

Summary of the invention

The technical problem that the invention will solve has been abandoned traditional method of utilizing bulk type timber material to make furniture or the wooden substantially curved section bar of ornament, and a kind of technical scheme that adopts corner bar small powder after the timber processing to be spliced into wooden curved section bar is provided.

Specifically describe and be for solving technical scheme that its technical problem provides: wooden curved section bar is that Mosaic face is spliced by the truncated prism body of predetermined quantity with warp or the parallel cross section of crossing wooden curved section bar curved surface flex point.Wherein, a symmetrical center line of truncated prism body Mosaic face joggle is parallel with Mosaic face, and another symmetrical center line is vertical with Mosaic face.

The invention technology, owing to adopt the little batten of truncated prism shape (piece) to carry out the splicing of tenon formula at the section of the warp of crossing the wooden curved surface flex point of setting or parallel, realized after splicing, replacing the purpose of large scale template material, and can satisfy changeableization of the curved surface requirement of wooden curved section bar with the timber processing little batten of tailing (piece).In wood-processing industry at present, cooperative mechanical mortise technology can make the wooden curved section bar that adopts the invention technology to be obtained cost at a specified future date be starkly lower than the wooden curved section bar process technology of existing timber.

Description of drawings

Fig. 1 is the organigram of the wooden curved section bar that provides of the invention, and Fig. 2 is an organigram of forming the little batten of truncated prism body of wooden curved section bar, and Fig. 3 is the organigram of forming before the truncated prism body splicing of wooden curved section bar.

The technical scheme that the invention provided is further described with following optimal way.

Wooden curved section bar is by the truncated prism body (1) of predetermined quantity, carries out the splicing of tenon formula and constitute on the cross section of the warp (2) of crossing wooden curved surface flex point or parallel (3).Wherein two crossing warps (2) and parallel (3) should at least one be the flex point section line of wooden curved section bar.The bar number of warp (2) and parallel (3), the complexity that changes according to wooden curved section bar curved surface, that is what of curved surface flex point, and the size of available timber processing tailing are decided by simple computation.

Adopt the tenon nuchal plane of each truncated prism body (1) of profile of tooth tenon (4) and the angle β on a surface of wooden curved section bar in this optimal way, should be 180 ° and deduct 1/2nd of turning α.

Claims

1, a kind of wooden curved section bar, it is characterized in that: wooden curved section bar is by the truncated prism body of predetermined quantity, so that the warp or the parallel cross section of wooden curved section bar curved surface flex point are that Mosaic face is spliced excessively, wherein, a symmetrical center line of truncated prism body Mosaic face joggle is parallel with Mosaic face, and another symmetrical center line is vertical with Mosaic face.

2, a kind of wooden curved section bar according to claim 1, it is characterized in that: when adopting the profile of tooth tenon to splice, the angle β on the tenon nuchal plane of each truncated prism body (1) and a surface of wooden curved section bar should be 180 ° and deducts 1/2nd of turning α.
