Detailed Description
The first embodiment is as follows: referring to fig. 1, the plastic-steel door and window profile with a multi-layer gap structure according to the present embodiment includes a profile body 1, and a plurality of gaps 101 are sequentially formed in the outer side wall of the profile body 1 from outside to inside.
In this embodiment, the number of the slits 101 is preferably 6, and the number of the slits 101 to be broken is at most 5 when the outer surface of the profile body 1 is impacted by 100 kg force through simulation experiments, so that the outer wall of the profile body 1 is too thick due to the excessive number of the slits 101, thereby not only increasing the weight of the profile body 1, but also increasing the manufacturing cost.
The second embodiment is as follows: referring to fig. 1, the width H of each slot 101 of the plastic steel door and window profile with a multi-layer slot structure according to the present embodiment is 1 mm-2 mm, and the length L1 of the slot 101 is smaller than the width L2 of the inner cavity of the profile body 1 and is larger than half of the width L2 of the inner cavity of the profile body 1.
Too long a slit 101 is unfavorable for extrusion molding, and too short a slit 101 cannot constitute a layer-by-layer stacked structure.
Other components and connection relationships are the same as those of the first embodiment.
And a third specific embodiment: referring to fig. 1, the distance between two adjacent slits 101 of the plastic-steel door and window profile with a multi-layer slit structure according to the present embodiment is 2mm.
The distance between two adjacent slits 101 is too small, and when the outer surface of the profile body 1 is impacted or pressed, a chain reaction occurs between the slits 101, so that all the slits 101 are destroyed.
Other components and connection relationships are the same as those of the first embodiment.
The specific embodiment IV is as follows: referring to fig. 1, the plastic-steel door and window section with the multi-layer gap structure according to the present embodiment further includes a cross-shaped supporting rib 2; the cross-shaped supporting rib 2 is inserted into the inner cavity of the profile body 1, and each supporting leg 201 of the cross-shaped supporting rib 2 is fixedly connected with one side wall of the inner cavity of the profile body 1. Other components and connection relationships are the same as those of the first embodiment.
Fifth embodiment: referring to fig. 1, the thickness of each leg 201 of the cross-shaped supporting rib 2 of the plastic-steel door and window profile with a multi-layer gap structure according to the present embodiment is the same as the wall thickness of the inner cavity of the profile body 1. Other compositions and connection relationships are the same as those of the fourth embodiment.
Specific embodiment six: referring to fig. 1, in the embodiment, two sides of the outer surface of a profile body 1 of a plastic-steel door and window profile with a multi-layer slot structure are provided with outer edges 102, and an inner side surface of each outer edge 102 is provided with a waterproof pressing strip clamping groove 103. Other components and connection relationships are the same as those of the first embodiment.
Principle of operation
