Abstract
The utility model discloses building square lumber for replacing a wood beam, comprising a square lumber body and a shell coated outside the square lumber body, wherein the square lumber body is formed by superposing two or more strip-shaped plates with the same length; the shell is formed by plates of metal or synthetic materials; and protecting plates are arranged at two ends of the square lumber body. The building square lumber saves timber resources, conforms to the spirit for establishing a 'novel wood beam material industry', has strong bearing capacity and controllable and low manufacturing cost, and is not easy to break, anticorrosive, anti-moth and fire-proof.
Description
Technical field
The utility model relates to a kind of structure material, particularly a kind of square bar for building that replaces flitch.
Background technology
In building and repairs profession, flitch is indispensable material, and the timber major part is all used at building trade, repairs profession, and furniture manufacturing industry.Flitch is processed by trees, though trees are renewable natural resources, trees are grown up to can make the time that flitch really needs decades, growth cycle is long, and the energy consumption of flitch industry is big, output capacity is low, environment pollution is serious, big to the natural resource destructive power.Therefore, the development course of world's flitch material industry has been set forth in Chinese flitch material Study on Industry Development report, has analyzed Chinese flitch material industry development present situation and gap, has proposed " novel flitch material industry " and substitute industrial concept in a creative way.At present, the flitch that uses in building and the repairs profession, price height not only, and, because the character of timber itself has determined low, the easy fracture of flitch bearing capacity, the defective of anticorrosion, mothproof, fire resistance property difference.
Summary of the invention
The purpose of this utility model is exactly at the deficiencies in the prior art, does not provide a kind of bearing capacity by force, easy fracture, anticorrosion, mothproof, fireproof do not replace the square bar for building of flitch.
For achieving the above object, the utility model adopts following technical scheme:
A kind of square bar for building that replaces flitch comprises the square bar body, and it is characterized in that: the external packets of described square bar body is covered with shell.Owing to coated shell in the outside of square bar body, utilize the bearing capacity of the rigidity raising square bar of shell, make not easy fracture of square bar.Simultaneously, shell can also play anticorrosion, mothproof, fireproof effect.
Preferably, described shell is fixedlyed connected with the square bar body.Can use iron nail, wood screw, bonding adhesive etc. fixing between shell and the square bar, make shell and square bar form an integral body, better effects if.
Preferably, described square bar body is by shaving board, density board, fiberboard, veneer, woodwork plate, one or more formations in the plastic plate.Because the square bar body is covered by in the shell, therefore any material that can make sheet material can be as the square bar body, and the material source of square bar is extensive, and it is the square bar body that the user can choose suitable material according to concrete use occasion, and promptly economy is practical again.
Further preferred, described square bar body is made of plastic plate, and described square bar body is a rectangular tubular, and its inside is provided with vertical and/or horizontal reinforcing rib.Plastics, also can be regenerated plastics by extrusion molding, form the square bar body because its inside is provided with quantity and the arrangement mode that vertical and/or horizontal reinforcing rib can design reinforcing rib as required, reach satisfactory supporting capacity.If adopt the PVC material can reach the fireproof requirement.
Preferably, described square bar body is by more than 2 or 2, and the identical rectangular plate of length is formed by stacking.The square bar body can be a material all in one piece, but also can be formed by stacking by the rectangular plate plate of polylith, can adopt the rectangular plate with material, also can adopt the rectangular plate of different materials, material source is extensive, and manufacturing cost can be adjusted according to the needs of use occasion, and is economical and practical.Rectangular plate preferably adopts the length length consistent with outer cover length, but also can adopt short rectangular plate to piece together mutually in the centre, staggers mutually but preferably will piece together head, to guarantee the bearing capacity of square bar.
Preferably, described shell is made of sheet of metallic material or synthetic materials plate; Described sheet of metallic material is a kind of in galvanized sheet, corrosion resistant plate, the cold-reduced sheet; Described synthetic materials plate is a kind of in regenerated plastics plate, the engineering plastics plate.Shell is best with metal material, and bearing capacity is strong, and is easy to process.Use the synthetic materials plate as sheathing material in the low occasion of requirement for bearing capacity, also can satisfy the demand,, can play anticorrosion, mothproof effect, if the PVC material can also play the fireproof purpose such as when fitting up furred ceiling.
Preferably, described shell is two, and shell is spill, fixedlys connected with square bar body two faces up and down respectively in two limits about shell.The spill shell can economical with materials, satisfies the requirement of bearing capacity simultaneously, about two spill shells, in the square bar body is strapped in, even the square bar body that is formed by stacking by the identical rectangular plate of length equally also can form an integral body.
Preferably, the two ends, the left and right sides of described square bar body are provided with backplate.Backplate shields, and prevents from transportation, carrying, installation process the end of square bar is broken.
Further preferred, described backplate is fixedlyed connected with the two ends, the left and right sides of square bar body.Can use iron nail, wood screw, bonding adhesive etc. fixing, make square bar body and square bar form an integral body.
Further preferred, described backplate is made of sheet of metallic material or synthetic materials plate; Described sheet of metallic material is a kind of in galvanized sheet, corrosion resistant plate, the cold-reduced sheet; Described synthetic materials plate is a kind of in regenerated plastics plate, the engineering plastics plate.As long as the material that can play a protective role may be used to backplate, elastomeric material such as rubber also can.
A kind of beneficial effect that replaces the square bar for building of flitch of the utility model is, saves timber resources, meets the spirit of foundations " novel flitch material industry ", the square bar bearing capacity by force, not easy fracture, anticorrosion, mothproof, prevent fires, manufacturing cost is controlled, cost is low.
