Full-sealing casement plastic-steel window

Abstract

The invention provides a full-sealing casement plastic-steel window, belonging to the field of fixed or movable closing device technology used for the opening of a building. The casement plastic-steel window solves the problem that the plastic-steel window has bad sealing performance and large heat dissipation amount and comprises a glass, a glass pressing strip, a sealing strip, a leaf material, an erecting material and a frame material; the leaf material invisible surface consists of a convex arc surface, a U-shaped trough and an inclined surface; the erecting material and the frame material invisible surface consists of a concave arc surface, a flat surface and an inclined surface; the leaf material invisible surface is overlapped to the erecting material or frame material invisible surface by a sealing strip supporter and is matched with the inclined angle surface of the erecting material or frame material; the sealing strip supporter is connected with the erecting material or frame material concave arc surface; and the leaf material or erecting material or frame material invisible surface is provided with a concave trough which is internally provided with the sealing strip. The full-sealing casement plastic-steel window not only shortens the section of the profile material, enlarges the daylighting surface of the window, improves the window yield of the profile, but also improves the wind pressure resistance, the heat-preservation performance and the sound insulation performance of the plastic-steel window, reduces the energy consumption and the cost, and has the advantages of good sealing effect and easy installation.

Description

1. Technical field [0001] The invention belongs to the technical field of fixed or movable closing devices for building openings, in particular to a casement plastic-steel window. 2. Background technology [0002] PVC plastic doors and windows are widely called plastic steel doors and windows in China. Plastic doors and windows are made of polyvinyl chloride (PVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, impact modifiers, ultraviolet rays, etc. Absorbent (shielding agent) and other additives are extruded to make door and window frame leaves by cutting, welding, etc., and are equipped with sealing rubber strips, hollow rubber strips, hardware and other accessories to make doors and windows. Due to the rigidity of the profiles, steel linings need to be added to the cavity of profiles exceeding a certain length. This kind of doors and windows are called plastic steel doors and windows. Divided into a number of closed small s...

Problems solved by technology

[0003] The object of the present invention is to provide a fully sealed casement plastic-steel window, which solves the problems of poor sealing performance and large heat dissipation of the plastic-steel window by changing the overlapping mode of the frame, stile and fan and increasing the overlapping area. It includes glass, Glass bead, sealing strip, fan material, stiff material and frame material, the non-visible surface of fan material is composed of convex arc surface, U-shaped groove and inclined surface, and the invisible surface of stiff material and frame material is composed of concave arc surface, Composed of flat and inclined surfaces, the non-visible surface of the fan material is overlapped with the non-visible surface of the jig material or frame material through the support of the sealing rubber strip, and cooperates with the bevel surface of the jig material or frame material. There are grooves on the non-visible surface of the material. The sealing rubber strip support is connected with the concave arc surface of the straight material or frame material. The sealing rubber strip support is composed of 3 to 5 grooves, long sides and long right-angled sides. A sealing strip is arranged in the groove, and grooves are respectively arranged on the upper and lower parts of the non-visible surface of the stiff material or frame material. In contrast, there are angle irons on the inside and outside of the four corners of the window frame where the frame materials are connected. In the sash assembly process of the present invention, the sealing rubber strip and the glass bead are used to buckle and fix the glass. Sealing strip support and sealing strips are added between the surfaces. After the frame is closed, it is divided into two independent chambers, airtight and watertight, by the sealing strips. At the same time, the airtightness and watertightness level of the plastic-steel window is improved, and rainwater cannot Infiltrated into the inner cavity and quickly discharged from the drain hole of the outer cavity, so that the whole window has good rainwater penetration resistance and excellent air tightness, and also reduces the section of the profile, expands the lighting surface of the window, and improves the profile. Window rate, save raw materials, improve the wind pressure resistance, thermal insulation performance and sound insulation performance of plastic steel windows, reduce energy consumption and cost, have the advantages of good sealing effect and easy installation
