Abstract
The utility model relates to a sectional bar material for doors and windows, particularly a novel energy-saving composite aluminum-plastic co-extruded frame sectional bar. The utility model is formed by combining aluminium linings and plastic materials. A plurality of cavities are added inside an outer plastic layer, and a water chute is arranged on the inner side of the outer plastic layer and forms an independent drainage channel with the cavities. The combining site of the aluminium linings and the plastic is provided with T-shaped or inverted L-shaped or inverted triangle or inverted trapezoid convexities. The utility model adds a plurality of cavities inside the outer plastic layer to cause the novel energy-saving composite aluminum-plastic co-extruded frame sectional bar to form a multiple-cavity structure, and solves the problem that the single-cavity structure of the existing sectional bars is a closing conductor which is not favorable for heat insulation and energy saving. Additionally, the formation of the cavities enables the utility model to be provided with an independent drainage system for smooth drainage. The convexities arranged on the combining site of the aluminium linings and the plastic can strengthen the bonding force of the aluminium linings and the plastic.
Description
One, technical field: the utility model relates to a kind of door-window section bar material, especially novel energy-conserving composite aluminium plastic co-extrusion frame section.
Two, background technology: plastic door-window has excellent heat insulation property and decay resistance, and working service is easy.But modulus of elasticity is little, and the non-deformability of section bar is poor, causes the door and window bulk strength low.The steel-plastic coextrusion door and window has good heat insulating ability, and same because the hardness of steel is big, thin portion moulding difficulty can't be processed too tiny structure, causes the steel-plastic coextrusion door and window not reach corresponding requirement on intensity, and does not have independently drain chamber.
Three, summary of the invention: the purpose of this utility model is exactly the defective that exists at prior art, and a kind of existing heat preservation energy-saving is provided, and increases the novel energy-conserving composite aluminium plastic co-extrusion frame section of its intensity again.
Its technical scheme is: by aluminium lining with plastic material is compound forms, and a plurality of cavitys of the inner increase of outer plastic layer, externally the plastic layer inboard is provided with guiding gutter, forms independently drainage channel with cavity.That the joint portion of described aluminium lining and plastics is provided with is "T"-shaped, inverted "L" shaped, del or the trapezoidal projection of falling.
The utility model externally plastic layer increases many cavitys, solves in the past that section bar list chamber structure is closed conductor, is unfavorable for the problem of heat preservation energy-saving, and the formation of cavity makes it have independently drainage system in addition, makes its draining smooth and easy.The projection that the joint portion of aluminium lining and plastics is provided with can increase its adhesion.
Four, description of drawings: accompanying drawing is this novel energy-conserving composite aluminium plastic co-extrusion frame section profile.
Five, specific embodiment:
By aluminium lining 1 with plastic material is compound forms, outer plastic layer 2 is inner to increase a plurality of cavitys 3, and externally the plastic layer inboard is provided with guiding gutter 4, with the formation of cavity 3 drainage channel independently.That the joint portion of described aluminium lining 1 and plastics is provided with is "T"-shaped, inverted "L" shaped, del or fall trapezoidal protruding 5.
Claims (2)
1, a kind of novel energy-conserving composite aluminium plastic co-extrusion frame section, by aluminium lining with plastic material is compound forms, it is characterized in that: a plurality of cavitys of the inner increase of outer plastic layer, externally the plastic layer inboard is provided with guiding gutter, forms independently drainage channel with cavity.
2, novel energy-conserving composite aluminium plastic co-extrusion frame section according to claim 1 is characterized in that: the joint portion of described aluminium lining and plastics is provided with "T"-shaped, inverted "L" shaped, del or the trapezoidal projection of falling.
