Description

A frameless glass window sash

Technical field:

The utility model relates to a window sash used for a push-pull window, in particular to a window sash structure with simple structure. the

Background technique:

Sliding windows are the most commonly used window structures in existing buildings, and their advantages are that they take up little space and are relatively convenient to use. The sash structure of the existing sliding windows generally uses profiles to form a frame shape, inserts glass in the groove of the frame profile, and then inserts another strip between the profile and the glass to fix the glass and the profile, or at the same time A sealing strip of rubber and plastic material is built into the groove between the profile and the glass to increase the sealing performance. The above-mentioned basic structure is relatively complex, with many manufacturing process steps, and the width of the profile is large and the amount of material used for the profile is large, and the aging of the rubber and plastic material will reduce the sealing performance and reduce the integrity between the glass and the frame. Cause the reduction of the wind pressure resistance capacity of the whole window sash and correspondingly increase the noise of the window sash in the windy state. Therefore how to solve the defect that the above-mentioned sash structure exists, it is very meaningful to design a new sash structure. the

Invention content:

The purpose of the invention of the utility model is to provide a glass window sash with simple structure, material saving and good structural strength. the

The technical solution for realizing the utility model is as follows: glass, especially the fixed frame for fixing the glass composed of upper edge, lower edge, side edge and middle edge made of at least one cavity profile around the glass , the glass is connected with an adhesive layer inside the concave cavity of the fixed frame. the

The inner surfaces of the side walls of the upper edge, lower edge, side edge and middle edge have concave-convex surfaces. the

A protruding portion is provided in the middle of the bottom edge of the upper edge, lower edge, side edge and middle edge, and the protruding portion has an opening. the

A sealing end is extended from one side of the middle sealing edge, and a strip-shaped groove for installing a sealing strip is also arranged on it. the

The other side wall extends from both sides of the upper edge and the lower edge, and the cross-sections of the upper edge and the lower edge are H-shaped. the

There are grooves on the same side of the upper edge and the lower edge. the

There are one or two grooves on the upper edge and the lower edge. the

The structure of the utility model is simple, and the edge sealing around the glass can be made of a thin metal profile with a concave cavity or an approximate [shaped profile. The strength of the connection is improved, so that the strength of the edge sealing and the glass are combined into one, completely avoiding the space between the glass and the profile in the prior art-that is, the gap that must exist in the embedded strip-shaped clips, resulting in insufficient wind pressure resistance. high defect. Compared with the structure of the prior art, the above-mentioned edge sealing structure can greatly save material and reduce the assembly workload, greatly reduce the total weight of the entire window sash, and improve the sealing performance, making it close to the sealing effect of the casement window. This is the effect that the existing sliding window is difficult to achieve. the

Detailed ways:

Please refer to Fig. 1-Fig. 4, the specific embodiment of the present utility model is as follows: comprise glass 1, the key is that glass 1 is surrounded by upper edge banding 2, lower edge banding 3, side edge banding prepared by at least one cavity profile 4 and the fixed frame of the fixed glass 1 formed by the middle sealing edge 5, the periphery of the glass 1 is placed in the concave cavity, and the adhesive is coated in the concave cavity, so that the glass 1 is connected with the concave cavity of the fixed frame with an adhesive layer 6, and the glue Layer 6 is arranged on both sides and the end face of the end of glass 1, and the adhesive of adhesive layer 6 can be used in multiple choices, depending on the specific use conditions, such as using high viscosity, or high density, or high Extensible or highly weather-resistant, such as silicone glue, neoprene, butyl glue, etc.; the glass 1 is tightly connected to the fixed edge by gluing, and there is no gap between the two that cannot be avoided in the existing technology , so that the overall strength is enhanced, and it can lead to the use of thinner materials for each edge while ensuring the strength requirements. the

There is a concave-convex surface 7 on the inner surface of the side wall of the above-mentioned upper edge seal 2, lower edge seal 3, side edge seal 4 and middle edge seal 5, and the concave-convex surface 7 can be composed of a plurality of grooves, which is beneficial to the preparation of profiles , especially the staggered connection between the above-mentioned uneven surface 7 and the adhesive layer 6 increases the frictional force, bonding performance and sealing performance between the adhesive layer 6 and the edge banding. the

The above-mentioned upper edge 2, lower edge 3, side edge 4 and middle edge 5 are provided with a protruding part 8 in the middle of the bottom edge. There are colloidal materials inside and outside of the space, which can increase the bonding strength between the adhesive layer 6 and the edge banding as a whole, and can also be used to screw the adjacent edge bands immediately after the edge banding and glass 1 are assembled as a whole using the above-mentioned protruding 8 are connected to further increase the strength of the overall frame, and the existence of the adhesive layer 6 can also increase the connection strength between the screw and the protruding part 8, so that the screw does not loosen. the

An approximately L-shaped sealing end 9 is extended from one side of the above-mentioned middle sealing edge 5, and a strip-shaped groove 10 for installing a sealing strip is also provided on it; When the fan sash and the window are in a fully closed state, the middle sealing edge 5 of the two sash has an overlapping area, that is, an approximately L-shaped sealing end 9 extends from one side of the middle sealing edge and has a fitting section with each other, so that through the two middle The air leakage air flow at the edge of edge sealing 5 must pass through multiple bending passages, thus improving the sealing performance of the sliding window, and the sealing strip installed in the strip groove 10 further seals the above-mentioned bending passages, which can make the sealing of the utility model Sex is greatly improved. the

Both sides of the upper edge band 2 and the lower edge band 3 extend the other side wall, the sections of the upper edge band 2 and the lower edge band 3 are H-shaped, and the upper edge band 2 and the lower edge band 3 of the H-type have visible windows Depending on the type or size of the fan, window wheels or window frame rails can be installed in the outer cavity of the H-type, or other required components can be easily installed to meet more structural requirements. the

There are grooves 11 on the same side of the upper edge banding 2 and the lower edge banding 3 above, and the grooves 11 of the upper edge banding 2 and the lower edge banding 3 are set as one or two, and the above grooves 11 are provided with sealing strips Seal the gap between the edge and the window frame; through the above-mentioned various sealing measures, the overall sealing performance of the utility model can basically reach the sealing performance of the casement window, which is considerably improved compared with the existing sliding window. the

The structure of the utility model is simpler than the prior art, but the structural strength is greatly improved. Compared with the existing profile structure, the edge sealing structure can save materials, and the choice of adhesive can be adapted to different regions and different buildings. Therefore, the utility model can be used as a new generation product of sliding windows, and has great economic and social benefits. the
