Abstract
The invention discloses a special-shaped metal purline. The purline is an upright Z-shaped beam and is composed of an upper wing plate, an upright plate and a lower wing plate which are mutually connected. The special-shaped metal purline disclosed by the invention, which serves as a constructional element of load-bearing joint steel, is the high-efficiency energy saving roof structure constructional element and can ensure that the maximum rigidity is obtained on the premise of using the fewest steel products.
Description
Technical field
The present invention relates to a kind of purlin, particularly relate to a kind of profiled metal purlin, belong to building field.
Background technology
The leakage problem of Now Domestic flat roof deck becomes owner and complains maximum problems, the most insoluble problem of Ye Shi infrastructure management company.In-depth investigation and research can find why flat roof deck occurs that the basic reason of so many problem adopts roofing technique to fall behind---gravity is superimposed Planting Techniques layer by layer.This roofing system have a large amount of use highly energy-consuming material and reliability low, be difficult to maintenance maintenance, life-span low feature.
The existing purlin installed for roofing, steel consumption is very large, the more complicated and fixed bearing gets up, because the quality of purlin is very large, the corresponding rising of design production difficulty of bearing, improve cost of production, result also in the meaningless waste of metal material, also create purlin space hold volume excessive.
Summary of the invention
For the defect that prior art exists, the invention discloses a kind of profiled metal purlin, improved by shape and structure, effectively control consumption and the spatial volume of steel, can ensure to obtain maximum rigidity, for industrialization fabricated roofing system provides a kind of energy-efficient roof structure component under minimally uses the prerequisite of steel.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of profiled metal purlin, described purlin is upright zigzag beam, is made up of interconnective upper flange, upright plate, lower wing plate.
By said structure, effectively control the consumption of steel, simultaneously because zigzag is as a kind of stable geometry, maintain again enough rigidity.
Further, described upper flange, lower wing plate have crimping at edge, and the crimping being positioned at upper flange edge is given prominence to downwards, and the crimping being positioned at lower wing plate edge projects upwards.
By above-mentioned bead structure, effectively surrounding fixing to being positioned at the support of purlin or other Structure composing, serving the firm effect strengthening roof structure.
In the present invention, the distribution mode of upper flange, upright plate, lower wing plate is not subject to special restriction, as long as it forms z font, preferably, described upper flange is parallel with lower wing plate, described upright plate and upper flange, lower wing plate are vertical, thus more effectively saving steel rolled steel dosage, also prevent the dead angle occurring when using bearing to support purlin not touching.
Similar with above-mentioned reason, described crimping is vertical with upper flange, lower wing plate respectively.
Profiled metal purlin of the present invention, is made up of metal material, and metal material used is not restricted, arbitrarily in this area can metal material all can be used for the present invention, include but not limited to be selected from carbon steel, alloy steel or aluminium alloys.
Further, on the basis of the above, profiled metal purlin of the present invention, also comprise bearing corresponding thereto, described bearing forms fixed support to upper flange, upright plate simultaneously, by forming support to upper flange, upright plate, can make the installation that purlin is stable, and due to the space constraint of crimping, there will not be and move or the contingency of movement.
By above-mentioned improvement, profiled metal purlin of the present invention is a kind of energy-efficient roof structure component as a kind of spandrel girder steel beam column, can ensure to obtain maximum rigidity under minimally uses the prerequisite of steel.
Accompanying drawing explanation
Fig. 1 is the structure chart of profiled metal purlin of the present invention.
Detailed description of the invention
With reference to figure 1, profiled metal purlin of the present invention is z character form structure, is made up of interconnective upper flange 1, upright plate 3, lower wing plate 2, and wherein upper flange 1, lower wing plate 2 are parallel, and perpendicular to upright plate 3.
Wherein, the edge of upper flange 1 has perpendicular outstanding crimping 4 downwards, and lower wing plate 2 edge has the perpendicular crimping 5. projected upwards
Be only one of the present invention shown in the above structure and accompanying drawing preferably to realize, those skilled in the art change the size of each several part on this basis, ratio, material, angle all belong to protection scope of the present invention.
Claims (2)
