[0004] The utility model discloses a kind of three -layer glass structures which can overcome the problems existing in prior art ordinary hollow glass, frame strength is high, glass and frame are firmly bonded, drying agent is invisibly placed, and good three -layer glass structure of aesthetic degree.

[0005] The utility model is realized by the following technical solutions:

[0006] The utility model discloses a frame and glass, and its characterized in that: the frame is closed frame surrounded by two cross beams and two longitudinal beams, the cross beam and the longitudinal beam adopt the same structure profile, the cross section of the profile is isosceles trapezoidal, and the cross beam and the longitudinal beam are welded connection, a circle of support edge is arranged in the middle of the inner side of the frame, the glass is three, and is fixed on the two sides of the frame and the support edge, forming three -layer hollow glass structure.

[0007] The profile is a PVC hard plastic profile.

[0008] The profile has a width of 5-10cm.

[0009] The frame has a square or rectangular shape.

[0010] The profile has grooves extending along the length on both sides.

[0011] The three pieces of glass and the frame are connected by adhesive.

[0014] The profile has a grid-shaped support rib in the inner cavity.

[0015] The beam or the support rib has a ventilation hole.

[0016] The beam or the support rib has a drying agent in the inner cavity.

[0017] The advantages of the present application are as follows: the welding frame support structure greatly improves the impact resistance of the three-layer glass structure; the glass is fixed on the frame, avoiding the occurrence of hollow glass leakage phenomenon, improving the quality of the hollow glass, reducing heat loss, and increasing the sealing space between the glass pieces. The welding connection between the beam and the support rib has better overall consistency; the frame profile is made of PVC material, and the thermal conductivity is about 0.007W / K, which is lower than the thermal conductivity of aluminum sealing strip, i.e. about 0.112W / K, i.e. the heat preservation performance is better; the cross section of the beam and the support rib profile is isosceles trapezoidal, so that the two side surfaces of the profile form an inclined surface, and the inclined surface also has an extending groove, which has an increased glue space when combined with the glass, and the adhesion strength between the two side glass and the frame is very high. The drying agent is placed in the inner cavity of the beam or the support rib, and the product has higher aesthetic degree. The different thicknesses between the glass pieces also make the sound produce different refraction in the present application, and avoid the resonance of sound waves, so that the sound insulation effect is remarkable.
