Description

Technical Field

[0001] The present application relates to the field of building wall panel design, and in particular to a composite decorative wall panel. Background Art

[0002] Composite wall panels are a new generation of high-performance building interior partitions produced industrially. They are made of a variety of building materials and replace traditional bricks and tiles. They have the obvious advantages of environmental protection, energy saving, pollution-free, lightweight, earthquake-resistant, fire-proof, heat-insulating, sound-insulating, and quick construction.

[0003] Currently, the front and back sides of existing composite wall panels are generally made of hard material layers, such as natural stone slabs, solid wood boards, etc. During the construction of composite wall panels, attention must be paid to the verticality and flatness of the wall surface, otherwise the composite wall panels will appear uneven after paving. In addition, due to the characteristics of the composite wall panels themselves, there will be certain gaps between the connections of adjacent composite wall panels. When the composite wall panels are uneven after paving, it is very difficult to handle the gaps, which may easily lead to uneven filling or falling off, thereby affecting the overall aesthetics and sound insulation effect of the wall surface, which needs to be improved. Utility Model Content

[0004] Based on this, the present application provides a composite decorative wall panel that can remain flat after each composite wall panel is laid to ensure the quality of subsequent caulking, so that the wall surface has good overall aesthetics and sound insulation effect.

[0005] The composite decorative wallboard provided in this application adopts the following technical solution:

[0006] A composite decorative wall panel comprises a facing plate, a rigid bracket arranged on the back of the facing plate and a base plate arranged on the back of the rigid bracket; a light steel frame is arranged on the inner side of the rigid bracket, a first steel member and a second steel member are elastically connected to two opposite sides of the light steel frame, a first clamping groove and a second clamping groove are arranged on two opposite sides of the rigid bracket, when the light steel frame is fixed to the facing plate, the first steel member is matched and clamped in the first clamping groove, and the second steel member is matched and clamped in the second clamping groove; a first toothed plate exposed to the rigid bracket is arranged on the side of the first steel member, and a second toothed plate exposed to the rigid bracket is arranged on the side of the second steel member, and the first toothed plate and the second toothed plate are bite-fitted with each other.

[0007] By adopting the above-mentioned technical scheme, the base plate is used for paving and bonding with the mortar layer on the building surface, so that the front side of the facing plate can be used as the surface layer of the composite decorative wallboard; by adding a rigid bracket and a light steel frame between the base plate and the facing plate, the weight of the entire composite decorative wallboard can be reduced while maintaining good structural strength, and after the light steel frame is installed on the inner side of the rigid bracket, the first steel member can be exposed in the first slot and the second steel member can be exposed in the second slot; when the composite decorative wallboard is paved, the first toothed plate of the first steel member and the second toothed plate of the second steel member on another adjacent composite decorative wallboard are engaged with each other, which can play a role in in-plane positioning, and is conducive to keeping each composite wallboard flat after paving, so as to ensure the quality of subsequent caulking, and make the wall surface have good overall aesthetics and sound insulation effect.

[0008] Optionally, the light steel frame includes a central base and four diagonal bracing members fixedly connected to the outer peripheral side of the central base, the diagonal bracing members are equidistantly arranged around the central axis of the central base, and when the light steel frame is fixed to the decorative panel material, the diagonal bracing members are respectively arranged corresponding to each diagonal line of the rigid support.

[0009] By adopting the above technical solution, by arranging each diagonal bracing member corresponding to each diagonal line of the rigid bracket, the structural strength of the composite decorative wallboard can be improved as much as possible while reducing the overall weight of the composite decorative wallboard, so that the decorated wall surface can maintain a good service life.

[0010] Optionally, the cross-sectional shape of the diagonal bracing member is a hollow rectangle, and the side of the diagonal bracing member is provided with a mounting groove connected to the interior; the first steel member is movably inserted in the mounting groove, and the outer side surface of the first steel member is provided with an outer retaining ring; a compression spring is connected between the first steel member and the inner wall of the diagonal bracing member, and the compression spring normally forces the outer retaining ring to rest against the rigid bracket, and at this time the first toothed plate is exposed on the rigid bracket.

[0011] By adopting the above-mentioned technical solution, after the diagonal bracing member is installed on the inner side of the rigid bracket, the elastic force generated by the compression spring acting on the first steel member can force the outer retaining ring to lean against the rigid bracket. At this time, the first toothed plate can remain exposed to the rigid bracket. When the composite decorative wall panels are laid, the composite decorative wall panels are directly forced to be laid vertically on the wall. After being subjected to the force, the first toothed plate can move inward and squeeze the compression spring, so as to quickly and conveniently complete the laying of the composite decorative panels and the straightness adjustment between adjacent composite decorative panels.

[0018] Optionally, the rigid bracket is provided with an outer edge plate near the side edge of the veneer plate, the width of the outer edge plate is greater than the width of the veneer plate, and the surface of the outer edge plate is provided with fish scale patterns.

[0019] By adopting the above-mentioned technical scheme, after the composite decorative panels are laid, the outer edge plates of two adjacent rigid brackets located on adjacent composite decorative panels can be pressed against each other. When the gaps between the wall panels are subsequently filled, the outer edge plates can serve as the inner carrier of the filler. The filler is bonded to the fish scale pattern of the outer edge plates and the decorative panels on both sides, which can increase the thickness of the filling and thereby extend the life of the filler.

[0020] Optionally, the facing board material is a natural stone slab, and the front side of the facing board material is provided with a flamed surface.
