Description

Technical Field

[0001] This application relates to the technical field of building crack resistance, and particularly relates to an anti-ground crack structure for fresh air ducts. Background Art

[0002] Building crack resistance is to prevent cracks from appearing on the surface of a building. If the cracks spread to the interior of the building, it will cause damage to the building. To avoid the ultimate damage to the building due to cracks in the building, an anti-ground crack structure is usually set inside or on the surface of the building to prevent cracks from appearing on the building surface and spreading to the interior of the building.

[0003] In modern residential buildings, in order to provide indoor ventilation, a fresh air system is generally installed. The fresh air ducts in the fresh air system are generally buried underground (in the floor) for fixation. The direct contact between the floor material and the fresh air duct will cause defects in the fresh air duct. And due to the ventilation of the fresh air duct, the fresh air duct will vibrate slightly. This slight vibration itself does not cause much harm to the ground structure, but long-term vibration will cause cracks in the floor material covering the fresh air duct, resulting in ground cracking. Summary of the Invention

[0004] Based on this, in view of the problem in the prior art that the ground cracks due to the vibration of the fresh air duct.

The fresh air duct is arranged on the base layer; the anti-ground crack structure includes an anti-crack fiberglass mesh and a steel mesh. The steel mesh covers the fresh air duct, the anti-crack fiberglass mesh covers the steel mesh, and the anti-crack fiber mesh is arranged in multiple layers.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this application more thorough and comprehensive.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific implementations and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0022] Please refer to Figure 1 , in one embodiment, a new air duct anti-cracking structure includes a base layer 5, a new air duct 1, and an anti-cracking structure 2. The new air duct 1 is disposed on the base layer 5; the anti-cracking structure 2 includes an anti-cracking fiberglass mesh 3 and a steel mesh 4. The steel mesh 4 covers the new air duct 1, the anti-cracking fiberglass mesh 3 covers the steel mesh 4, and the anti-cracking fiberglass mesh 3 is provided in multiple layers.

[0023] Specifically, the base layer 5 is a floor. The new air duct 1 of the fresh air system is arranged in the floor, that is, below the ground. A layer of steel mesh 4 is further arranged on the upper side of the new air duct 1, which can improve the strength of the cement foaming layer and prevent cracks from appearing due to the vibration of the new air duct 1. In addition, the steel mesh can also protect the new air duct 1 and prevent it from being deformed by the structure arranged on it. Multiple layers of anti-cracking fiberglass meshes 3 are arranged on the upper side of the steel mesh 4. The anti-cracking fiberglass meshes 3 can increase the strength of the floor material (the floor material covering the new air duct 1, the floor layer 12 in the following text, simply speaking, is the floor part covering the new air duct 1), improve the anti-tensile property of the floor material, and prevent cracks from appearing inside the ground. Then the internal cracks spread to the ground and cause the ground to crack. The multi-layer arrangement of the anti-cracking fiberglass meshes 3 can provide a buffering effect, buffer the impact of the vibration of the new air duct 1 on the floor material, reduce the stress inside the floor material, and prevent cracks from appearing inside the floor material. The width of the steel mesh can also be only about 10 centimeters wider than the width of the new air duct 1, or it can be laid in the whole layer.

[0024] The above new air duct anti-ground crack structure can achieve the following technical effects. A steel mesh 4 is provided on the upper surface of the new air duct 1, and a layer of anti-crack fiberglass mesh 3 is added on the steel mesh 4. Then, floor materials are laid on the anti-crack fiberglass mesh 3. The anti-crack fiberglass mesh 3 and the steel mesh 4 can increase the strength and anti-tensile properties of the floor materials. When affected by external forces, the floor materials have sufficient strength and do not crack; the anti-crack fiberglass mesh 3 also has a buffering effect. Setting multiple layers of anti-crack fiberglass mesh 3 can reduce or eliminate the force of the vibration of the new air duct 1 on the floor materials, thereby reducing or eliminating the damage of the vibration generated by the ventilation of the new air duct 1 to the floor materials. Both the anti-crack fiberglass mesh 3 and the steel mesh 4 are porous structures. When laying the floor materials, the floor layer materials can pour the anti-crack fiberglass mesh 3 and the steel mesh 4 into the floor materials through the mesh holes, thereby improving the strength and anti-tensile strength of the floor materials.

[0025] In addition, the present application also provides some more specific implementation manners to improve the above structure.

[0026] Further, in order to improve the sound insulation effect and the shock absorption effect, the anti-ground crack structure 2 further includes a protective layer 8. The protective layer 8 includes a polyurethane rubber sound insulation pad 6. The polyurethane rubber sound insulation pad 6 covers the base layer 5, and the new air duct 1 is disposed on the polyurethane rubber sound insulation pad 6.

[0027] Specifically, a polyurethane rubber sound insulation pad 6 is provided on the base layer 5, and other structures are all disposed on the polyurethane rubber sound insulation pad 6, so that the polyurethane rubber sound insulation pad 6 can well reduce the noise generated by all the structures disposed on it. At the same time, the polyurethane rubber sound insulation pad 6 can buffer the impact of all the structures on it on the base layer 5 and prevent the base layer 5 from being damaged.

[0028] Further, in order to further buffer the impact generated by the vibration of the new air duct 1, the protective layer 8 further includes a cement foam layer 7. The cement foam layer 7 covers the polyurethane rubber sound insulation pad 6, and the new air duct 1 is disposed in the cement foam layer 7.

[0029] Specifically, a cement foam layer 7 is provided on the polyurethane rubber sound insulation pad 6. The cement foam layer 7 has a large load-bearing capacity and good seismic resistance. The large load-bearing capacity ensures that the cement foam layer 7 can bear the structure above it without being damaged. As long as the cement foam layer 7 is not damaged, the ground will not collapse or crack due to the minor deformation of the base layer 5, thus damaging the integrity and flatness of the ground. The good seismic resistance can ensure that the vibration of the fresh air duct 1 will not cause deformation or cracks in the base layer 5, thus ensuring that the ground will not crack due to the defects of the base layer 5. The polyurethane rubber sound insulation pad 6 provided between the base layer 5 and the cement foam layer 7 can avoid the rigid contact between the base layer 5 and the cement foam layer 7, thereby protecting the base layer 5 and the cement foam layer 7 from large defects.

[0030] Further, a water distribution pipe 9 is provided in the cement foam layer 7.

[0031] Specifically, in general residential buildings, water distribution pipes 9 are generally laid underground for water supply. The laying of the water distribution pipes 9 can also cause the ground to crack. Therefore, in order to prevent the ground from cracking caused by the laying of the water distribution pipes 9, the water distribution pipes 9 are also arranged below the anti-cracking fiberglass mesh 3 and the steel mesh 4 and in the cement foam layer 7. The anti-cracking fiberglass mesh 3 and the steel mesh 4 reduce the impact of the water distribution pipes 9 on the ground and prevent them from damaging the ground from the inside, thereby causing the ground to crack and form cracks. In addition, when the water distribution pipes 9 are in water supply, they will also generate noise. By arranging them in the cement foam layer 7 and above the polyurethane rubber sound insulation pad 6, the polyurethane rubber sound insulation pad 6 reduces the noise generated by the water distribution pipes 9.

[0032] Further, in order to ensure normal heating in winter, the fresh air duct anti-ground cracking structure further includes a floor heating pipe 13, and the floor heating pipe 13 is arranged in the cement foam layer 7.

[0033] Specifically, heating devices are installed in most residential buildings in the north, and floor heating pipes are the heating equipment most commonly used at present. Since hot water flows in the floor heating pipe 13, the flow of hot water in the floor heating pipe 13 will also generate noise. Therefore, the floor heating pipe 13 is arranged above the polyurethane rubber sound insulation pad 6, and the polyurethane rubber sound insulation pad 6 isolates the noise generated by the floor heating pipe 13 from affecting the residents below. The floor heating pipe 13 also generates heat. In order to better transfer the heat to the ground, the floor heating pipe 13 should be arranged in the cement foam layer 7 to fully transfer the heat to the ground for heating. Since vibration will be generated when there is water flow in the floor heating pipe, in order to reduce the impact of the vibration of the water pipe on the ground, the floor heating pipe 13 is arranged below the anti-cracking fiberglass mesh 3 to reduce the impact of the vibration of the floor heating pipe 13 on the ground and prevent the ground from cracking due to the vibration of the floor heating pipe 13.

[0034] Further, to prevent the ground from cracking, the anti-ground-cracking structure of the fresh air duct further includes a floor layer 12, and the floor layer 12 includes a first floor layer 10 which covers the anti-cracking fiberglass mesh 3 and the steel mesh 4.

[0035] Specifically, a first floor layer 10 is covered on the anti-cracking fiberglass mesh 3 and the steel mesh 4. The first floor layer 10 is relatively thin and can cover the anti-cracking fiberglass mesh 3 and the steel mesh 4, ensuring that the anti-cracking fiberglass mesh 3 and the steel mesh 4 can maximize the strength and anti-tensile properties of the floor layer 12. Moreover, the first floor layer 10 has low requirements for the surface smoothness, as long as it is level, which can reduce the construction difficulty and cost to a certain extent.

[0036] Further, to make the floor layer 12 more beautiful, the floor layer 12 further includes a formed floor layer 11 which covers the first floor layer 10, and the thickness of the formed floor layer 11 is 1 cm to 2 cm thicker than that of the first floor layer 10.

[0037] Specifically, the entire floor layer 12 is divided into a first floor layer 10 and a formed floor layer 11. The layered floor can reduce the overall stress inside the floor layer 12 and prevent large cracks from appearing in the floor layer 12 due to stress concentration, finally causing the entire ground to crack. Since the first floor layer 10 is relatively thin and cannot bear too much pressure, when the ground is subjected to a large force, the first floor layer 10 is prone to cracking. Therefore, the thickness of the formed floor layer 11 should be 1 cm to 2 cm thicker than that of the first floor layer 10. When it is too thin, the strength of the entire floor layer 12 is insufficient, and when it is too thick, stress concentration is likely to occur inside the formed floor layer 11 and the formed floor layer 11 is prone to cracking. The surface of the formed floor layer 11 should be as smooth and flat as possible to improve the overall effect of the ground.

[0038] Further, to further reduce the impact of the vibration of the fresh air duct 1 during ventilation on the floor layer 12, a buffer cushion layer is wound around the outside of the fresh air duct 1.

[0039] Specifically, winding a buffer cushion layer around the outside of the fresh air duct 1 can further reduce the impact of the vibration generated by the fresh air duct 1 during ventilation on the floor layer 12, minimizing the impact generated by the vibration at the source of the vibration, and then basically eliminating the impact generated by the vibration of the fresh air duct 1 through other buffer means. The buffer cushion layer can be made of materials such as rubber or sponge.

[0040] Further, to prevent the fresh air duct 1 from rusting when buried underground for a long time, an anti-rust layer is wound around the outside of the fresh air duct.

[0041] Specifically, the fresh air duct 1 is generally made of metal. Setting the fresh air duct 1 underground, the long-term contact between the moisture in the ground and the fresh air duct 1 will cause the fresh air duct 1 to rust. Over time, the fresh air duct is prone to damage. Once the fresh air duct 1 is set underground, it is very difficult to replace. Therefore, an anti-rust layer is wound around the outside of the fresh air duct. The anti-rust layer can be made of waterproof materials such as tin foil or other water-impermeable materials.

[0042] Furthermore, for the convenience of winding around the outside of the fresh air duct 1, the buffer cushion layer and the anti-rust layer can be set as one layer. The fresh air duct is wound with PE foam plastic or geosynthetic materials (non-woven fabric). These two materials can isolate moisture while buffering, and can avoid the contact between the moisture in the ground and the fresh air duct 1 while buffering the vibration of the fresh air duct 1, ultimately causing damage to the fresh air duct 1.

[0043] Through the above implementation methods, the anti-ground crack structure of the fresh air duct in the embodiment at least achieves the following technical effects:

[0044] A steel mesh 4 is provided on the upper surface of the fresh air duct 1, a layer of steel anti-crack fiberglass mesh 3 is added on the steel mesh 4, and then the floor layer 12 is laid on the anti-crack fiberglass mesh 3. The anti-crack fiberglass mesh 3 and the steel mesh 4 can increase the strength and anti-tensile properties of the floor layer 12. When affected by external forces, the floor layer 12 has sufficient loudness without cracking; the anti-crack fiberglass mesh 3 also has a buffering effect. Setting multiple layers of anti-crack fiberglass mesh 3 can reduce or eliminate the force of the vibration of the fresh air duct 1 on the floor layer 12, thereby reducing or eliminating the damage to the floor layer 12 caused by the vibration generated by the fresh air duct 1 due to ventilation. The polyurethane rubber sound insulation pad 6 in the protective layer can buffer while increasing the sound insulation effect, reducing the impact of the force generated by vibration around the fresh air duct 1 on the floor layer 12 and the base layer 5. By setting the floor layer 12 in layers, the stress concentration in the floor layer 12 is reduced, preventing the floor layer 12 from cracking from the inside due to stress concentration, ultimately resulting in the cracking of the floor layer 12 and the cracking of the ground.

[0045] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0046] The above-described embodiments only represent several implementation manners of the present application. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
