Problems solved by technology

[0005] In the prior art, most of the plastic-steel doors directly use the plastic-steel door frame as the threshold or even have no threshold structure. Directly using the plastic-steel door frame as the threshold not only affects traffic, but also has a short service life. After a long period of trampling, the door frame will be deformed and cannot be used normally; If the plastic-steel door directly uses an all-metal threshold, although the strength of the threshold is improved and the service life is prolonged, the thermal insulation of the metal threshold is poor, far inferior to that of plastic steel; performance requirements

Embodiment 1

[0037] Such as Figure 1-4 shown.

[0038] A composite threshold for a plastic-steel door, comprising an aluminum threshold 1, an intermediate plastic threshold 2, and an invisible plastic threshold 3 that are sequentially matched and connected; Supporting feet A1-3 and sealing grooves 1-5; the middle plastic threshold 2 is provided with a corrugated plane B2-1, hardware positioning grooves 2-2, door leaf mating surface B2-3, and L-shaped supporting feet B2-4; It shows that the invisible plastic threshold 3 is provided with a corrugated plane C3-1 and a door leaf mating surface C3-2. When the composite threshold for the plastic-steel door is matched with the door leaf, the side sealing rubber strip on the door leaf is squeezed with the door leaf mating surface B2-3 and the door leaf mating surface C3-2 to ensure the sealing between the threshold and the door leaf.

Embodiment 2

[0040] The composite threshold for a plastic-steel door as described in Example 1 differs in that the aluminum threshold 1 is made of aluminum alloy; the middle plastic threshold 2 and the invisible plastic threshold 3 are made of plastic steel.

Embodiment 3

[0042] The composite threshold for plastic-steel doors as described in Embodiment 1 is different in that the aluminum threshold 1 , the middle plastic threshold 2 and the invisible plastic threshold 3 are connected by buckles.

Abstract

The invention relates to a combined doorsill for a plastic-steel door and a utilization method of the combined doorsill for the plastic-steel door. The combined doorsill comprises an aluminum doorsill, a middle plastic doorsill and a hidden plastic doorsill in sequential matched connection. The aluminum doorsill comprises a waved slope, a waved plane A, L-shaped supports A and a seal groove; the middle plastic doorsill comprises a waved plane B, a hardware positioning groove, a door leaf matching plane B and L-shaped supports B; the hidden plastic doorsill comprises a waved plane C and a door leaf matching plane C. Since the length of the waved slope of the aluminum doorsill can be changed according to different types of doors, and the middle plastic doorsill and the hidden plastic doorsill are in universal structures, the combined doorsill for the plastic-steel door has the advantages of high applicability and high universality.

Description

[0001] Technical field: [0002] The invention relates to a composite threshold for a plastic-steel door and a method for using the same, belonging to the technical field of building doors and windows. [0003] Background technique: [0004] Door frames and thresholds are important components of plastic steel doors; they are an important part to ensure the performance of doors and windows and anti-theft performance. [0005] In the prior art, most of the plastic-steel doors directly use the plastic-steel door frame as the threshold or even have no threshold structure. Directly using the plastic-steel door frame as the threshold not only affects traffic, but also has a short service life. After a long period of trampling, the door frame will be deformed and cannot be used normally; If the plastic-steel door directly uses an all-metal threshold, although the strength of the threshold is improved and the service life is prolonged, the thermal insulation of the metal threshold is p...
