Description

Technical Field

[0001] The utility model relates to the technical field of spraying construction, in particular to a special net positioning structure for spraying construction. Background Art

[0002] In the construction industry, the development of wall materials has always been a focus of considerable attention. Traditional wall construction techniques present numerous challenges. For example, the construction process is characterized by a low degree of mechanization and reliance on extensive manual labor, resulting in low efficiency. Furthermore, traditional walls suffer from relatively poor integrity, resulting in insufficient seismic resistance in the face of natural disasters such as earthquakes. For a long time, my country's wall materials have primarily consisted of small-block materials such as sintered bricks, small hollow concrete blocks, and autoclaved aerated concrete blocks. However, with the continuous advancement of construction technology and the diversification of building needs, wall materials are gradually developing towards a more diverse range, with the rise of panel-based wall systems such as lightweight slats and composite wall panels.

[0003] In recent years, the rapid industrialization of construction has placed higher demands on wall construction technology. Cast-in-place spray-in-place composite wall systems have emerged in this context and are continuously expanding in practical applications. Lightweight steel frame-gypsum board composite walls represent a representative example of this new wall application technology. These systems help reduce the overall weight of buildings, lowering the load-bearing requirements on foundations. They are also relatively simple to install, shortening construction cycles. While gypsum board and some strips offer some fire resistance, they are susceptible to impact damage and may experience slight deformation over time and environmental changes. Furthermore, gypsum board requires installation and splicing piece by piece, requiring a complex process and resulting in a relatively slow construction process. However, spraying phosphogypsum allows for rapid, large-scale application, saving construction time. It also tightly fills gaps between lightweight steel studs, forming a more robust, integrated structure. The gypsum board and the light steel frame are mainly connected by connectors, and are slightly inferior in terms of stability. For example, when subjected to vibration or uneven external force, local loosening or deformation may occur. The gypsum board composite wall may have weak points such as board seams, which have a certain impact on sound insulation and heat insulation. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the technical problem solved by the present invention is to provide a special net positioning structure for spraying to improve the seismic resistance of traditional walls in the face of natural disasters such as earthquakes, thereby improving the safety of buildings. At the same time, the wall has a high degree of mechanization, high construction efficiency, good integrity and good seismic resistance.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is: a special spray-constructed net positioning structure, which is characterized in that: it includes a light steel keel, which is arranged in multiple arrangements, and a plurality of through holes are provided on the light steel keel, and a plurality of limiting rods are provided in the through holes and pass through the through holes to cooperate with the light steel keel for connection; a limiting groove is provided on one side of the light steel keel, and a glass fiber mesh is provided on the limiting groove, and a pressure plate is provided on the limiting groove to cooperate with the limiting groove; a limiting net is provided on the end of the light steel keel away from the glass fiber mesh, and the limiting net is fixedly connected to the light steel keel through a limiting tube provided on one side of the light steel keel by a limiting rod.

[0006] The beneficial effects of this solution are: combining gypsum-based mortar as spraying slurry, achieving overall spraying and compounding through mechanical spraying method, greatly improving the degree of mechanization and significantly improving construction efficiency. At the same time, due to its good integrity, it performs well in earthquake resistance and can better ensure the safety and stability of the building. The setting of the limit groove provides accurate positioning for the installation of the fiberglass mesh, ensuring that the fiberglass mesh is accurately positioned and laid flat, which is conducive to its reinforcing effect. The limit mesh is fixedly connected to the limit cylinder on one side of the light steel keel through the limit rod, further enhancing the stability and reliability of the structure and being able to withstand larger construction loads.

[0007] Furthermore, the light steel keel is arranged in a T-shaped structure, and a sound insulation board is arranged between the light steel keel and the fixing rod. The light steel keel with a T-shaped structure itself has good bending and torsional resistance, can enhance the stability of the entire wall structure, and withstand greater loads. The light steel keel with a T-shaped structure and the sound insulation board arranged at a specific position are easier to position and install during the construction process, thereby improving construction efficiency.

[0008] Furthermore, the height of the limit groove is less than the height of the light steel keel. The relatively low limit groove makes it easier to install and fix the fiberglass mesh or other materials, thereby improving construction efficiency. At the same time, the low limit groove makes the wall surface smoother, which is beneficial for subsequent decoration and processing.

[0009] Furthermore, the pressure plate is arranged in a U-shaped structure, and the two ends of the pressure plate are connected with the limit groove. The pressure plate is made of galvanized steel plate. The two ends of the U-shaped structure can fit tightly with the limit groove to improve the stability and sealing of the connection. The steel plate material itself has high strength and rigidity, and can provide sufficient pressure to fix materials such as fiberglass mesh to ensure its stable position.

[0010] Furthermore, the limiting net is a long galvanized steel wire mesh. The galvanizing treatment can effectively prevent the steel wire from rusting and corrosion, thereby extending the service life of the limiting net. In particular, it can maintain stable performance in humid or harsh environments, and help to evenly distribute the stress on the wallboard, avoid local stress concentration, and improve the overall stability and durability of the wallboard. At the same time, the long shape enables the steel wire mesh to be combined with the phosphogypsum sprayed wallboard over a larger area to form a whole, thereby enhancing the structural integrity of the wallboard.

[0011] Furthermore, the upper end of the limit rod is arranged in a circular pancake structure, and the limit rod is movably connected to the limit cylinder. The circular pancake structure increases the contact area with the limit cylinder, making the connection more stable and reducing the possibility of loosening. The larger contact area helps to disperse the force, improve the bearing capacity of the connection between the limit rod and the limit cylinder, alleviate the stress concentration at the connection, make the force distribution more uniform, and enhance the reliability of the structure.

[0012] Furthermore, the pressure plate is flush with the end face of the light steel keel after being matched with the limiting groove. Being flush with the end face of the light steel keel can avoid damage to people or objects caused by the protruding part, thereby improving safety in use. During subsequent construction processes, such as applying mortar and installing other components, there will be no obstruction due to the protrusion of the pressure plate, thereby improving construction efficiency. The flush design enables the light steel keel and the pressure plate to form an overall plane, which helps to improve the integrity and stability of the wall structure.

[0016] Example 1 is basically as shown in the attached Figure 1-2 As shown: a special spraying net positioning structure includes a light steel keel 1, which is arranged in multiple pieces and is arranged in a T-shaped structure. A plurality of through holes 2 are provided on the light steel keel 1, and a limiting rod 10 is provided in the through hole 2. The limiting rod 10 passes through the light steel keel 1 through the through hole 2, and a sound insulation board 7 is provided between the limiting rod 10 and the light steel keel 1. The sound insulation board 7 is limited and fixed by the limiting rod 10 and the light steel keel 1.

[0017] Limiting grooves 4 are set on both sides of the light steel keel 1, and the limiting grooves 4 are welded on the sides of the light steel keel 1. A limiting rod 10 is set on the limiting grooves 4. The limiting rod 10 is set in a U-shaped structure, and when the limiting rod 10 is connected with the limiting groove 4, the limiting rod 10 is set flush with the light steel keel 1. A glass fiber mesh 6 is set between the limiting groove 4 and the limiting rod 10, and the glass fiber mesh 6 is fixed between the limiting groove 4 and the limiting rod 10.

[0018] A limiting net 9 is set on the end of the light steel keel 1 away from the glass fiber mesh 6. The limiting net 9 is a long strip limiting net 9. The limiting net 9 is laid on the light steel keel 1, and a plurality of limiting cylinders 8 are set on one side of the light steel keel 1. A limiting rod 10 is set on the limiting net 9. The limiting rod 10 is connected with the limiting cylinder 8, and the circular cake structure set on the limiting rod 10 can better limit and fix the long strip limiting net 9.

[0019] When in use, the glass fiber mesh 6 is fixed at the position of the light steel keel 1 through the pressing plate 5, and the long limiting mesh 9 is fixed on the light steel keel 1 through the limiting rod 10. The phosphogypsum is sprayed on the glass fiber mesh 6 by the spraying equipment. Since there is a gap between the glass fiber mesh 6 and the sound insulation board 7, the phosphogypsum is sprayed in the gap, which makes the wall integrity good, and the glass fiber mesh 6 can be better combined with the phosphogypsum. The phosphogypsum filling in the gap increases the overall density of the wall, further improving the strength and stability of the wall; on the other hand, it makes full use of the space, The structural performance of the wall is optimized, and the sound insulation and heat preservation functions of the wall are enhanced. The positioning structure, glass fiber mesh 6, and long limiting mesh 9 provided on both sides of the single-row light steel keel 1 enable the spraying material to be effectively constrained and positioned when the wall is sprayed by the spraying equipment. The positioning structure ensures the accurate installation of the glass fiber mesh 6 and the long limiting mesh 9, providing a stable foundation for the spraying operation. The glass fiber mesh 6 enhances the crack resistance of the wall, and the long limiting mesh 9 further strengthens the overall structural strength. During the spraying process, the spraying material can be evenly distributed and firmly adhered, reducing material waste. At the same time, they help to form a flat and uniform wall surface, improving the quality and aesthetics of the wall, and have high construction efficiency, good integrity, and good seismic performance.
