Description

Fireproof glass window frame

Technical Field

The utility model belongs to the technical field of door and window, concretely relates to fire prevention glass window frame.

Background

The fire-proof window is made of steel window frame, steel window sash and fire-proof glass, and can isolate and prevent fire from spreading. Generally, the opening or the skylight is arranged on the building outer wall at the position with insufficient fireproof space, and the parts needing to be observed and the like and the outer wall opening part needing to be vertically spread in a fireproof manner are arranged on the fireproof wall or the fireproof partition wall in the building. The window frame structure of the fireproof window is a part for fixing fireproof glass, and plays a key role in the fireproof performance of the fireproof window.

In the installation process of the fireproof window body, a fireproof strip is required to be attached to the lap joint of the window frame and the window sash of the fireproof window, and the fireproof strip is mainly used between the door leaf and the door frame of a steel door and a wooden door and between the door leaf and the door leaf. When a fire disaster happens, the fire-proof strips automatically expand to block the gap between the door and block the air circulation between the two spaces, thereby effectively preventing the harm of the early dense smoke, toxic gas and hot gas of the fire disaster to the human body and controlling the fire spread. The fireproof strip can be adhered in the groove of the fireproof door seam by glue (adhesive sticker is adhered), but the fireproof strip is easy to fall off due to long-term opening and closing of the window sash, and the problem needs to be solved urgently.

Detailed Description

The invention will be further explained with reference to the drawings:

example 1:

as shown in figure 1, a fireproof glass window frame comprises a frame body 1, a lap joint rod 2 connected to the lower end of the frame body 1 and a fireproof strip fixedly connected to the tail end of the lap joint rod 2, wherein the fireproof strip is connected with the lap joint rod 2 through a rivet 6, the surface of the lap joint rod 2 is far away from the two ends of the cross section of the fireproof strip to form a tilting 31, the middle part of the fireproof strip is close to the surface of the lap joint rod 2 to form a recess 32, and the rivet 6 is fixed in the recess 32 in the middle.

The tail end of the lap joint rod 2 is wavy and at least comprises two adjacent convex waves 21 and a concave wave 22 positioned between the two convex waves 21, the fire protection strip is fixed in the concave wave 32 through a rivet 6, and two sides of the fire protection strip extend towards the direction far away from the surface of the lap joint rod 2 under the guidance of the convex waves 21 to form a tilting 31.

The tail end of the lap joint rod 2 is designed into a wave shape, the fluctuation of the convex waves 21 and the concave waves 22 is skillfully utilized, the toughness of the fireproof strip is combined, the middle part of the section of the fireproof strip is sunken 32 and fixed in the concave waves 22, two sides of the section of the fireproof strip extend upwards along the convex waves 21, the sunken 21 and the tilting 31 are naturally formed, the tilting 31 can be rapidly expanded in case of fire, the gap between the window sash and the window frame is rapidly filled, and the fireproof effect is good.

In other embodiments, it is within the scope of the present invention to replace the rivet 6 with a screw.

Example 2

As shown in fig. 2, in the same situation as in embodiment 1, the end of the overlapping rod 2 is provided with an open slot, which includes a first slot wall 61 and a second slot wall 62 protruding from the surface of the overlapping rod 2, the middle part of the fire-proof strip is fixed in the open slot by a rivet 5, and the two sides extend towards the first slot wall 61 and the second slot wall 62 and are overlapped on the first slot wall 61 and the second slot wall 62 to form a tilting 31.

The side wall of the open slot is ingeniously utilized, the fire protection strip is not clamped in the open slot but is erected on the side wall of the open slot, an upward tilting 31 is naturally formed, the structure is novel, the fire protection strip can rapidly expand in case of fire, and the fire protection effect is good.

Example 3

As shown in fig. 3 and 4, in the same manner as in example 1 except for the other features, the fire-retardant strip includes a base 33 and protrusions 35 provided on the base 33, the lower surface of the base 33 is disposed to abut against the surface of the lap lever 2, the protrusions 35 are provided on both sides of the upper surface of the base 33, and the protrusions 35 are formed to be raised. The convex body 35 has a hollow structure. The lower surface middle part indent of base member 33 forms interior recess 36, and rivet 5 passes from the centre, compresses tightly the contact with interior recess 36 and overlap joint pole 2 surface, and the overlap joint pole 2 surface is kept away from at fire prevention strip both ends, and the perk is kept away from the overlap joint pole 2 surface more. The structure of fire prevention strip has taken sunken 33 certainly and has stood up, only need with the fire prevention strip fix on the overlap joint pole 2 can, still be equipped with interior concave part 36 on the fire prevention strip, when rivet 5 fixes the fire prevention strip on the overlap joint pole 2, interior concave part is automatic to pressing to overlap joint pole 2, convex body 35 on the fire prevention strip upwarps to both sides more, fire prevention strip can expand rapidly when the conflagration, the fire prevention effect is better.

The above description is the preferred embodiment of the present invention, and for those skilled in the art, modifications of the various equivalent forms of the present invention are within the scope of the appended claims of the present application without departing from the principle of the present invention.
