In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of square anti-corrosion purlin, cross section is
Square, one group opposite side is double-decker, which is formed by connecting in opposite directions by two units that section is groove type.
Further, described two unit sizes are identical, both side walls are cross-linked the square purlin of composition up and down.
Further, another unit is contained within side and forms square purlin by the groove type side wall of one of unit.
Further, it is additionally provided with reinforcing rib inside the square purlin.
Further, the reinforcing rib uses two identical sections to be formed by connecting back-to-back for concave structure, reinforcing rib
It is vertically connected between two units.
Further, the purlin is made of glass-reinforced plastic material.
The invention further relates to the method for the square purlin, comprise the following steps：
Glass fibre is carried out with unsaturated polyester (UP) to mix impregnation, mold cured is then added and is shaped to cellular construction, then in list
Meta structure part to be connected carries out gluing, is finally bonded and is cured, obtains square anti-corrosion purlin.
Further, the glass fibre and unsaturated polyester (UP) are by weight 30-40:60-70 carries out mixing impregnation, impregnation
When be additionally added curing agent and catalyst.
Further, the forming temperature is 70-90 DEG C, molding time 6-9min.
Further, during the gluing, thickness 0.1-0.3mm, the time for being bonded solidify afterwards is more than 5min.
The invention has the advantages that：
1st, square anti-corrosion purlin is formed by connecting in opposite directions using two units that section is groove type, and one group opposite side is double
Rotating fields, compared to traditional one-time formed purlin of drawing, its short side part thickness increases by one, its stretching can be substantially improved
Intensity and flexural strength, and conveniently adopt and be screwed.
2nd, due to using spliced technique, compared to the technique of drawing extrusion, its molding time significantly shortens, using traditional work
One production line of skill square purlin per minute for being only capable of producing 17cm, and structures and methods using the present invention, energy per minute
The square purlin of 9m is enough produced, production capacity is substantially improved, and the repetition that can reduce growth line is set, and significantly saves production cost,
Improve work efficiency.
3rd, square anti-corrosion purlin provided by the invention, has excellent corrosion resistance, is resistant to different degrees of acid, alkali, has
The corrosion of the various liquid mediums such as solvent and salt, it is reasonable in design, it is unlikely to deform, light weight, intensity is high, anti-aging property
It is good, by it is suitable for the high industrial building of requirement for anticorrosion.
