Problems solved by technology

[0006] In view of the above-mentioned deficiencies in the thermal stability, mechanical properties, water resistance, and aging resistance of the artificial boards made of wood / bamboo natural materials and plastics, some companies also use glass fiber reinforced plastics (glass reinforced plastics) to make plank boards. The mechanical properties, aging resistance and service life are much higher than those of preservative wood and the above two man-made panels, but its high cost and industrialized appearance are not appreciated by the industry, so it is rarely used

Embodiment 1

[0052] Depend on figure 1 As shown, the cross-section of the thermosetting biological fiber composite reinforced plank profile described in this embodiment is a rectangular tube, and the specific dimensions of the cross-section are 145 mm in external width and 25 mm in height; the length of the internal cavity is 135 mm and the internal height is 15 mm. The internal structure is the surface reinforcement layer 1, the strength layer 2 and the main material 3 from the outside to the inside. The thickness of the surface reinforcement layer 1 is 1mm, and the thickness of the strength layer is 1-1.5mm; it uses thermosetting synthetic resin as the base material, and Glass fiber mat, glass fiber roving and biological fiber are longitudinally and continuously laid on the bottom surface 7 of the profile and the elevations 5 on both sides for composite reinforcement; the profile is produced by a pultrusion process.

Embodiment 2

[0082] Depend on figure 2 , Figure 5 As shown, the cross-section of the thermosetting biological fiber composite reinforced plank profile described in this embodiment is rectangular, and the specific dimensions of the cross-section are the width of the upper surface 4 is 145 mm, the height is 12 mm, and the width of the bottom edge band 701 is 12 mm. The upper surface 4 is a plane, and the surface adopts sanding treatment, and there are longitudinal wear marks on it. Both sides of the side facade 5 are respectively provided with an upper clamping strip 502 and a lower clamping strip 503, the upper clamping strip 502 has a horizontal width of 10mm and a thickness of 6mm, and the lower clamping strip 503 has a horizontal width of 8mm and a thickness of 6mm. This embodiment adopts the installation method of bonding the profile and the load-bearing wooden beam with the adhesive 9; it can also be used in combination image 3 Screw direct fastening installation shown. The rest ...

Abstract

The invention discloses a profile and a production technology for a wooden trestle. According to the profile, thermoset resin serves as a matrix, and the technical scheme that a biological fiber and glass fiber composite reinforced internal structure is adopted, high-strength glass fiber felt and rough yarn are placed on the vertical edges and the outer side of the bottom of the profile, and stress faces are especially reinforced is adopted. Compared with anti-abrasion wood, plastic wood, bamboo scrimber and other gallery road pavement materials widely used in the prior art, in various engineering properties, the profile has the advantages that strength is high, weight is low, the profile is resistant to ageing, and energy conservation and environment protection are achieved; meanwhile, the profile has the appearance similar to that of natural wood, anti-abrasion and anti-slip treading texture and the advantages of being low in cost, high in productivity, convenient to construct, long in service life and high in cost performance. After application and popularization, total ownership cost of the service life cycle can be effectively reduced, excessive demand for natural wood can be greatly reduced, and environment protection is benefited.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a thermosetting biological fiber composite reinforced plastic plank profile. Background technique [0002] The plank road originally refers to a kind of plank road built along the cliffs. Our country has built plank roads as early as the Warring States period. The Baoxie plank road in southern Shaanxi starts from Baogukou in Hanzhong in the south and ends at Xieyuguan in Meixian County in the north. 235 kilometers long, it was an important military hub connecting the north and the south in ancient times. It is often said that "the road to Shu is difficult, and it is difficult to go to the blue sky" is to praise the vastness and steepness of its projects. The overhead passages between tall buildings in ancient China are also called plank roads. Plank roads now have a wider meaning. They are usually set up on seashore beaches, lakeside streams, river banks,...
