Abstract

The utility model provides a structure-improved plastic door panel, which is mainly characterized in that the small squares on both ends of a hollow door panel which is composed of a plurality of equal interval squares are additionally provided with more intensive reinforcing ribs symmetrically to replace solid strip type rods used for fixing hinges on the door panel; the rectangular spaces outside the squares on both ends are respectively provides with an inclined reinforcing rib in order to enhance the bearing force of the door panel, and furthermore, the door panel is not easy to be deformed. The left side and the right side of the door panel are additionally provided with protruding ribs which play the sealing function. When a door frame has smaller deformation and the size of the door frame has errors, the structure-improved plastic door panel can be processed easily.

Description

Structure-improved door panel of plastics

The utility model relates to the plastic door-plate that uses in a kind of building construction.

The door-plate that uses in the building construction at present mostly is timber-work or metal, glass product.Influenced by moisture laden air, the timber damage of ftractureing easily, metal is easily oxidated, and is more apt to rot or get rusty when especially being used in bathroom, lavatory door, influence application life, and cost is higher.

In view of the above-mentioned shortcoming of metal and timber-work, the plastic goods with its be not afraid of water logging, can not get rusty, the life-span is long, bright advantage, is subjected to use more and more widely.Especially its whole compression molding, it is fast to have more speed of production, and the advantage that cost is low, but the north material door-plate of producing at present are because the problem on the structure design also has some shortcomings.(see figure 1) such as door-plate insufficient strength in the time of will adorning hinge (4) on the door-plate (1), in the hollow grid (2) of dress hinge one side, need be put into the solid bar (3) of timber or other material, so that the screw (5) of Fixed hinge is penetrated in advance.In addition, door-plate four limits will be equipped with edge sealing bar (6) and (7) respectively.The edge sealing bar (6) of its left and right sides causing cracking to come off owing to the vibrations of opening in long-term the use at closing time easily.

The purpose of this utility model is to overcome the above-mentioned shortcoming that exists in the plastic door-plate of present production.And its structure is improved.

The purpose of this utility model is achieved in that in the hollow grid at two ends, the door-plate left and right sides, symmetry has increased many concentrated type reinforcing steels, in the hollow grid outside the grid of two ends, respectively is added with an oblique reinforcing steel respectively, remove the edge sealing bar of the left and right sides, increasing on both sides of the edge has outstanding muscle.

Description of drawings:

Fig. 1 is the structural representation of the present plastic door-plate of producing.

Fig. 2 is the structural representation of the utility model plastic door-plate.

Fig. 3 is the plan structure schematic diagram of the utility model plastic door-plate.

The utility model is described in further detail below in conjunction with accompanying drawing:

In the hollow grid (2) at the two ends, the left and right sides of the hollow plastic door-plate (1) that is made of a plurality of uniformly-spaced hollow grids, symmetry has increased many concentrated type reinforcing steels (8) and had replaced the past for the timber hinge is installed packs in advance or the solid bar (3) of other material screw to be passed many reinforcing steel Fixed hinges.The concentrated type reinforcing steel of both sides symmetry is non-directional in order to use, be convenient to install, remove the edge sealing bar of the left and right sides, increased outstanding muscle (9) respectively, both need not worry owing to the aging edge sealing bar fracture that causes of vibrations or binder, come off, and be convenient to again when door-plate is installed door-plate to be processed when meeting doorframe and have small deformation or size that error is arranged.The edge sealing bar (7) of both sides still gives reservation because of stressed little, not easy to crack in using up and down.In order to strengthen door-plate intensity, in other each hollow grid of door-plate, increased an oblique reinforcing steel (10).

The utility model compared with prior art owing to do not need solid bar and edge band (6), has reduced material consumption, has improved production efficiency, is convenient to assembling. Improve door-plate intensity, prolonged service life. And the processing when being convenient to install.

Claims

The plastic door-plate that constitutes by a plurality of uniformly-spaced hollow grids that a kind of building construction is used, it is characterized in that: symmetry has increased many concentrated type reinforcing steels in the hollow grid at door-plate two ends, in the hollow grid outside the grid of two ends, respectively be added with an oblique reinforcing steel, remove the edge sealing bar of the left and right sides, and on both sides of the edge, increased outstanding muscle.
