Description

Technical Field

[0001] The utility model relates to the technical field of building decoration industry, in particular to a special dry hanging system for overhead stones. Background Art

[0002] With the improvement of living standards, people pay more and more attention to interior decoration. When decorating, they usually make suspended ceilings on the ceiling. In order to pursue decorative effects, most people will choose stone for suspended ceilings. Over-the-top stone is a part that has special requirements for installation methods.

[0003] As the name suggests, overhead stone is the part that is higher than the human head when installed. Its installation method is the same as the conventional stone indoor dry hanging method. It is achieved by opening holes on the back of the stone and using the back bolt technology to connect, fix and reinforce it. Then, by adding bolts and flexible gaskets, the system instability caused by vibration is reduced.

[0004] However, the existing indoor stone dry-hanging system has not completely eliminated the loosening of the dry-hanging stone structure caused by vibration and the failure of the fixed structure caused by the brittleness of the stone itself. At the same time, no anti-fall measures are taken for overhead stones. In addition, it has high requirements for back-bolting technology, a long on-site installation cycle, and complicated procedures. It does not conform to the concept of green construction and is not convenient for subsequent maintenance.

[0005] Although the Chinese patent with authorization announcement number CN106351416B discloses an overhead stone dry hanging structure that can reduce the bending, deformation and brittle cracking of stone, the following problems still exist:

[0006] 1. For super-long stone slabs, there is still a serious risk of falling and cracking in the long direction;

[0007] 2. The structure has slots and holes in a small area, which may cause the stone to break and crack.

[0008] 3. The structure has relatively concentrated fixing points, which poses a risk of stress concentration and does not take into account the uniform stress distribution of the stone as a whole;

[0009] 4. This structure is only a combination of a back bolt and a T-shaped hanger, and the structural functions are repeated and redundant.

[0010] Therefore, how to provide a special dry hanging system for overhead stone that meets the needs of on-site construction has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0011] The purpose of the utility model is to address the deficiencies of the prior art and provide a special dry hanging system for overhead stones, which has stronger stone integrity and lower stone brittleness.

[0012] The utility model provides a special dry hanging system for overhead stones, comprising an angle steel and a stone facing assembly, wherein the angle steel and the stone facing assembly are connected by a plurality of double connection assemblies; the stone facing assembly comprises an overhead stone and a reinforcing rib bonded to the back of the overhead stone, the reinforcing rib is arranged parallel to the long side direction of the overhead stone, a plurality of obliquely arranged plug holes are opened on the overhead stone at the connection with the reinforcing rib, and a bent clamping arm is provided on the side of the reinforcing rib away from the overhead stone; the double connection assembly comprises a connecting hanger and a dry hanging part, a clamping groove arranged corresponding to the clamping arm is provided on the connecting hanger, and a plugging arm arranged corresponding to the plugging hole is provided on the dry hanging part, one end of the connecting hanger is connected to the angle steel, and the other end is clamped and connected to the clamping arm on the reinforcing rib through the clamping groove, and one end of the dry hanging part is connected to the angle steel, and the other end is tightly plugged and connected to the plug hole on the overhead stone through the plugging arm.

[0013] The angle steel is connected to the civil engineering main body through the square tube, and the angle steel and the square tube are connected to form a keel assembly.

[0014] The angle steel and the square tube are fixedly connected by full welding.

[0015] In order to make the connection tighter, a plurality of reinforcing holes are provided on the reinforcing ribs at the junction with the overhead stone. The reinforcing ribs are fixed to the overhead stone by adhesive, and the adhesive passes through the reinforcing holes to form adhesive nails.

[0016] In order to make the connection tighter, the reinforcement hole is in the shape of an elongated strip.

[0017] The cross section of the reinforcing rib is a U-shaped one with the opening being arranged away from the overhead stone. The clamping arms are bent and arranged on the two arms of the reinforcing rib, and the clamping arms on the two arms are arranged face to face.

[0018] In order to reduce installation costs and facilitate installation, the connecting hangers and dry hangers are connected to the same position of the angle steel in groups of two by bolt connectors.

[0019] In order to further improve the earthquake resistance, insulating rubber gaskets are provided between the corresponding connecting hangers and dry hangers.

[0020] In order to make the overall structure light and reduce the weight it bears, the reinforcing ribs and connecting hangers are all made of aluminum profiles.

[0021] In order to make the connection tighter, the plug-in arm is inserted into the plug-in hole and is tightly connected by AB glue.

[0022] The present invention strengthens the overall rigidity of the overhead stone by bonding reinforcing ribs arranged along its long sides to the back of the overhead stone, while avoiding the risk of stone edge collapse and cracking caused by drilling in the prior art. It is particularly suitable for use with extra-long overhead stones. Connecting hangers and dry hanging parts are added between the reinforcing ribs and the angle steel, and between the overhead stone and the angle steel, respectively, to form a double-connection structure, making the force more uniform and the anti-fall effect better. The connecting hangers are connected to the reinforcing ribs by snapping, which improves the earthquake resistance. The dry hanging parts are connected to the overhead stone by plugging, making the fixation more secure, the structure more stable, and the force greater. The present invention is safe and stable, has an effective structure, is economical and environmentally friendly, and fundamentally eliminates the risk of overhead stone dry hanging falling. At the same time, it strengthens the strength and integrity of the stone. It can be widely used in indoor dry hanging stone overhead positions, and is particularly suitable for use in areas with high requirements for earthquake resistance and crack prevention.

[0047] The utility model clamps the dry hanging piece 32 with the overhead stone 21 and fills the connection gap with AB glue 7 to form a whole; at the same time, the overhead stone 21 and the reinforcement rib 22 are also formed into a whole under the pulling of the glue nail 51, and the stone facing component 2 is completely clamped with the connecting hanger 31 through the reinforcement rib 22; at this point, a double connection port appears at the fixed end of the overhead stone 21, and the double connection port is firmly bolted to the keel component on the civil engineering main body through the fixing piece. It has a simple structure, a wide range of applications, and is suitable for large-scale promotion. It can structurally reduce or even eliminate the safety and quality risks brought by the overhead dry hanging stone, and at the same time, solve the problems that the decorative effect is greatly affected by human labor and the later maintenance is difficult.
