Description

Technical Field

[0001] This utility model relates to the field of building decoration materials technology, specifically to a combined overhead keel. Background Technology

[0002] Developing prefabricated buildings and prefabricated decoration is conducive to saving resources and energy, reducing construction pollution, improving labor productivity and quality and safety levels, accelerating the transformation of the construction industry's production methods, comprehensively improving building quality, and achieving energy conservation, emission reduction and sustainable development.

[0003] Keel is a commonly used building material in prefabricated buildings and decoration, used to support shapes and fix structures. Depending on the materials used, it can be divided into wood keel, light steel keel, aluminum alloy keel, steel keel, etc.; according to the location of use, it can be divided into ceiling keel, vertical wall keel, partition wall keel, floor keel, and hanging keel, etc.; according to different decoration and construction techniques, there are also load-bearing and non-load-bearing keels, i.e., keels that can be walked on and keels that cannot be walked on, etc.

[0004] In the existing technology, the disadvantages of wooden keel are that it is not fireproof or moistureproof, it is easy to deform over time, and the cutting and installation are time-consuming and labor-intensive; steel keel is generally made of 0.6 thick galvanized sheet, with simple shape, low strength, troublesome assembly, and single function, and can generally only be used as ceiling slabs; profile keel does not have installation holes, and drilling is required on the construction site, which is time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the prior art and provide a combined overhead keel to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A modular overhead keel includes several base profiles and several surface profiles; the base profiles have a U-shaped cross-section, and several snap-fits are evenly arranged on their left and right side plates; several assembly holes are evenly arranged on the base plate of the base profile along its length; the surface profiles have a U-shaped cross-section, and the tops of their left and right side plates are bent inwards and then bent downwards to form hooks; during assembly, the surface profiles are perpendicular to the base profiles, and the hooks at the tops of the two side plates of the surface profiles are fastened and fixed to two adjacent snap-fits on the base profiles.

[0008] Preferably, the bottom plate of the bottom profile is provided with an upwardly V-shaped bottom reinforcing rib A along its length; the two side plates of the bottom profile are provided with corrugated side reinforcing ribs A along their length.

[0009] Preferably, the bayonet is shaped like an inverted "V", with the lower part of the bayonet opening upwards in a C shape, and the upper parts of both sides having a smooth arc transition.

[0010] Preferably, the bottom plate of the surface profile is provided with an upwardly V-shaped bottom reinforcing rib B along its length direction; the two side plates of the surface profile are provided with corrugated side reinforcing ribs B along their length direction.

[0011] Preferably, the angle α at the end of the hook of the face profile is 80°-85°.

[0012] Beneficial effects: Compared with the prior art, the keel style of this utility model is novel. It is stronger and more durable by increasing the strength through multiple reinforcing ribs. The assembly is also particularly simple. The two profiles only need to be snapped together. It can be used not only for ceilings, but also for walls or floors. Attached Figure Description

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings and specific embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0020] Reference Figure 1 The combined overhead keel described in this embodiment includes several bottom profiles 1 and several surface profiles 2. Both the bottom profiles 1 and the surface profiles 2 are made of 1.0-thick galvanized sheet. Traditional keels are more durable and stronger.

[0021] like Figure 2-4As shown, the bottom profile 1 has a U-shaped cross-section, and several slots 11 are evenly distributed on its left and right side plates. Correspondingly, as... Figure 5 As shown, the cross-section of the surface profile 2 is U-shaped, and the tops of its left and right side plates are bent inward and then bent downward to form hooks 22.

[0022] During assembly, the face profile 2 is perpendicular to the bottom profile 1, and the hooks 22 at the top of the two side plates of the face profile 2 are fastened and fixed to the two adjacent slots 11 of the bottom profile 1, as shown. Figure 1 As shown.

[0023] To achieve an ideal fastening effect, ensuring easy operation and convenient use during fastening, while maintaining a firm and reliable connection, the latch 11 and hook 22 are cleverly designed. Specifically, the latch 11 is shaped like an inverted "V," with rounded upper parts on both sides for easy fastening, and an upward-opening C-shape at the bottom to prevent the hook 22 from easily falling off after fastening. In other words, the latch design achieves the effect of easy fastening but not easy detachment. Furthermore, the bending angle α at the end of the hook 22 of the surface profile 2 is not 90°, but rather 80°-85° (preferably 80°). This ensures that the end of the hook 22 easily fastens within the latch and is not easily detached, facilitating construction and providing a secure connection.

[0024] The base plate of the base profile 1 has a plurality of mounting holes 14 evenly provided along its length for installing and fixing bolts to the wall, facilitating on-site installation. After the face profile 2 is fastened and fixed to the base profile 1, wall tiles or ceiling decorative panels can be hung on the back of the face profile 2, enabling convenient and quick decoration work.

[0025] The bottom profile 1 has an upwardly V-shaped reinforcing rib A12 on its bottom plate along its length; the two side plates of the bottom profile 1 have corrugated side reinforcing ribs A13 along their length. The top profile 2 has an upwardly V-shaped reinforcing rib B21 on its bottom plate along its length; the two side plates of the top profile 2 have corrugated side reinforcing ribs B23 along their length. The design of the reinforcing ribs greatly enhances the strength of the profile itself, making the profile less prone to deformation.

[0026] The techniques not described in detail in this document are technical means well known to those skilled in the art.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
