Abstract
The present invention relates to a light-weight building material 1 used for a building structural member. The light-weight building material 1 at least comprises three wall plates formed by single block of galvanized iron plates, namely a first wall plate 11, a second wall plate 12 and a third wall plate 13 which form a triangular section. A circular section can also be used, preferably a rectangular section. The galvanized iron plates can be cut to form the light-weight building material 1 by a cold rolling method.
Description
Technical field
The present invention relates to a kind of constructional materials in general, relates in particular to a kind of light-weight building material that is applied to building structural member.
Background technology
Along with our forest promptly reduces, wood supply begins deficiency and is inconsistent on grade.This makes timber must be difficult to accept as the expense cost height of constructional materials.For many years, building contractor and developer are forced is seeking the expense cost that substitution material reduces construction of buildings always.Past has proposed many methods, and the light-weight building material of metal manufacturing is used for building structural member, for example roof framework or similarly structure, however before the present invention, effect also is not very encouraging.In the practice of many prior aries, the assembly of described framework is that the metal sheet by the U-shaped cross section constitutes.In one embodiment, the end of the dual-side in described U-shaped cross section is folded up tightly and is formed an abundant double-layered edges.In the prior art practice, the top chord forms inverted U-shaped cross section, and this inverted U-shaped cross section has from the terminal outwardly directed flange of its each side, so that bigger rigidity to be provided.
One of main difficulty that many prior aries practices of manufacturing metal roof framework exist is that the bottom chord adopts different assemblies with the top chord, causes two different production lines of needs or at least two different production line schemes.And, must the different spare package of stock's two classes.In addition, because described top chord has flange,, should cut away the flange of at least one top chord on described framework top.
Because the not too favourable U-shaped shape of this constructional materials, process and use quite difficulty of this constructional materials, building has been increased unnecessary expense cost.The strength and stiffness of this constructional materials are also doubtful.The present invention now tries hard to address these problems to small part, if not the words of whole solutions.
Summary of the invention
Therefore, first purpose of the present invention provides a kind of light-weight building material and uses for building structural member.
Another object of the present invention provides a kind of building structural member that is applied to, and has the light-weight building material of quite high strength and stiffness.
Another object of the present invention provides a kind of building structural member that is applied to, long-term antirust light-weight building material.
Above these and other objects of the present invention are by a kind of light-weight building material, have a main shaft and a wallboard part, described wall plate is divided into the metal sheet of a lengthwise, this metal sheet forms annular wall in the plane perpendicular to described main shaft, this annular wall comprises at least three wallboards, wherein two wallboards are provided with a ruggedized construction, and this ruggedized construction is a plurality of gauffers or ribs, and each described gauffer or ribs all extend on the direction of cardinal principle perpendicular to described main shaft direction.
Description of drawings
By reading the detailed description of being done in conjunction with the accompanying drawings subsequently, the present invention may be better understood, in the accompanying drawing:
Fig. 1 illustrates a kind of light-weight building material of a kind of embodiment of the present invention.
Fig. 2 illustrates a cross section of described light-weight building material.
The specific embodiment
See Fig. 1 now, it illustrates a kind of light-weight building material of a kind of embodiment of the present invention, and Fig. 2 shows a cross section of this light-weight building material.This light-weight building material 1 has a main shaft and a wallboard part 11, and this wall plate branch comprises at least three wallboards, but is different from the U-shaped cross section of prior art, and the present invention uses a kind of triangular-section.But preferably comprise four wallboards, i.e. the square-section of first wallboard 12, second wallboard 13, the 3rd wallboard 14 and wall plate 15.Perhaps, also can use circular cross-section.The parts in this closed cross section have been eliminated in the prior art practice to increasing the needs that strength and stiffness are folded to form double-layered edges.
This light-weight building material 1 is made of the single metal plate part, and described metal sheet is useful with the zinc plated mild carbon steel plate.Described metal sheet is cut into required size, roll, form described light-weight building material 1.This is simple and easy, a single continuous process operation.
For this light-weight building material 1 is shaped, at first to form one first interlocking structure 31 at an end of metal sheet, form one second interlocking structure 32 at its another end.When metal sheet was rolled on roll forming machine, first interlocking structure 31 and 32 engagements of second interlocking structure were got up, and form described light-weight building material 1.In order further to strengthen described seam, can use rivet along the described path of contact of interlocking structure.
In order further to strengthen this light-weight building material, can make described first and second wallboards 12,13 have a kind of ruggedized construction 2.Described ruggedized construction 2 can be many ribs or the fold that forms on wallboard 12,13.
It will be understood by those skilled in the art that and to carry out some modifications and variations and not break away from the spirit and scope of the invention the present invention.Therefore above stated specification only is for illustrative purposes rather than will limits the spirit and scope of the invention by any way.
