Description

Technical Field

[0001] The utility model relates to the field of building technology, in particular to glass installation technology, and specifically to a keel for glass installation. Background Art

[0002] In the aspect of building glass installation, a keel is required. The commonly used keel has a complex structure, consists of two or more parts, and is synthesized into one part by stamping, with poor material stability. Figure 1 The shown keel structure is a relatively simple one in the market. It is only synthesized into one part by stamping after two parts are arranged in a dislocation and back-to-back manner. The two parts are fixed to each other and the structure of each part itself is complex. When in use, more parts need to be added to assist the bolts for fixation, making the installation process cumbersome, not only with low installation efficiency but also with possible installation risks. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a keel for glass installation aiming at the problems existing in the prior art.

[0004] The purpose of the utility model is solved by the following technical solutions:

The contact surfaces of the two steel profiles placed back-to-back and symmetrically are welded by hot melt welding, and the same sides of the two steel profiles can form a keel locking cavity for accommodating a keel locking piece.

[0006] The steel profile is composed of a regular U-shaped structure and two inverted U-shaped structures arranged side by side. The two inverted U-shaped structures are respectively located on both sides of the regular U-shaped structure and share adjacent surfaces. The height of the outer side surface of the inverted U-shaped structure is less than the height of the adjacent surface shared by the inverted U-shaped structure and the regular U-shaped structure.

[0007] The inner cavity width of the regular U-shaped structure is greater than the inner cavity width of the inverted U-shaped structure.

[0008] The inner cavity width of the regular U-shaped structure is not less than twice the inner cavity width of the inverted U-shaped structure.

[0009] The keel locking cavity is composed of the same-side inverted U-shaped structures of different steel profiles that are symmetrically arranged and have opposite opening directions; the middle opening of the keel locking cavity is a keel locking opening, and a connecting piece is inserted into the keel locking cavity from the keel locking opening to connect and fix the keel locking piece; both sides of the keel locking opening are the free edges of the outer side surfaces of the inverted U-shaped structures of different steel profiles.

[0010] The free edge of the outer side surface of the inverted U-shaped structure has a folded edge, and the folded edge integrally formed with the outer side surface of the inverted U-shaped structure can seal part of the opening of the corresponding inverted U-shaped structure.

[0011] The corresponding flanges on the two steel profiles are parallel to each other and can support the keel locking member.

[0012] Threads are arranged on the outer wall of the flange.

[0013] At the bottom of the inner cavity of the positive U-shaped structure of the steel profile, there are evenly spaced hot melt welding spots, and the hot melt welding spots are located on the steel profile above the keel.

[0014] The steel profile is integrally formed by precision continuous cold bending of a single-layer steel plate.

[0015] The utility model has the following advantages compared with the prior art:

[0016] For the keel of the utility model, only two steel profiles with the same structure are placed back to back symmetrically and then welded and bonded by hot melt welding. The bonding strength is high and it is not easy to open when subjected to lateral force.

[0017] The keel of the utility model is fixed by a screw-type tensioning structure composed of a keel locking member and screw studs, so as to realize the four-point balanced fixation of the glass. The structure is stable and the glass will not be damaged; the screw-type tensioning structure will not damage the spraying surface of the keel, so it is not easy to rust; during the production and installation process, the fixation of the screw-type tensioning structure only requires the operator to rotate the screw studs through tools to ensure that the stress points of each screw stud are consistent.

[0025] For a single steel profile 1, the steel profile 1 is composed of a straight U-shaped structure 11 and two inverted U-shaped structures 12 in parallel, the two inverted U-shaped structures 12 are respectively located on both sides of the straight U-shaped structure 11 and share adjacent surfaces, the outer surface height of the inverted U-shaped structure 12 is less than the shared adjacent surface height of the inverted U-shaped structure 12 and the straight U-shaped structure 11, and the inner cavity width of the straight U-shaped structure 11 is greater than the inner cavity width of the inverted U-shaped structure 12; on the basis of the above structure,.

[0026] On the basis of the above structure, the keel locking cavity 2 is composed of the same-side inverted U-shaped structures 12 of different steel profiles 1 that are symmetrically arranged and have openings facing opposite directions. The middle opening of the keel locking cavity 2 is the keel locking opening 21. The connecting piece is inserted into the keel locking cavity 2 from the keel locking opening 21 to connect and fix the keel locking piece 5. At this time, the two sides of the keel locking opening 21 are respectively the free edges of the outer sides of the inverted U-shaped structures 12 of different steel profiles 1.

[0027] On the basis of the above structure, the free edge of the outer side surface of the inverted U-shaped structure 12 has a folded edge 3, and the folded edge 3 integrally formed with the outer side surface of the inverted U-shaped structure 12 can seal the partial opening of the corresponding inverted U-shaped structure 12. The corresponding folded edges 3 on the two steel profiles 1 are parallel to each other and can support the keel locking piece 5, so that the two folded edges 3 support the keel locking piece 5, and the two sides of the keel locking piece 5 of the U-shaped structure support the inner wall of the outer side surface of the keel locking cavity 2, forming a four-point balanced fixation of the glass; a further preferred option is that a thread is arranged on the outer wall of the folded edge 3.

Screws and studs are sequentially passed through the locking pressing plate, the keel locking port 21, and the keel locking member 5. The screws and studs are further rotated, so that the keel locking member 5 is pulled closer to the corresponding locking pressing plate until the two folding edges 3 abut against the inner cavity bottom of the U-shaped keel locking member 5, and the two sides of the U-shaped keel locking member 5 abut against the inner wall of the outer side of the keel locking cavity 2, forming a four-point balanced fixation for the glass; finally, a cover plate is configured on the outer side of the locking pressing plate to complete the arrangement.
