Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a heat-insulating and energy-saving steel structure wall. Background Art

[0002] A steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates. Welds, bolts or rivets are usually used to connect between the components or parts. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields.

[0003] For example, the steel structure wall disclosed in the publication number CN208415586U includes an inner wall panel, a steel structure body and an outer wall decoration material layer. The steel structure body is arranged between the inner wall panel and the outer wall decoration material layer. A waterproof and breathable membrane is arranged under the outer wall decoration material layer. A plate body is arranged under the waterproof and breathable membrane. A heat-insulating layer is arranged between the plate body and the inner wall panel.

[0004] However, in the prior art, although steel structure walls are widely popular in the construction field due to their high strength, light weight and convenient construction, when such walls are hit externally, dents are likely to appear on the surface. In addition, the performance of steel structure walls in terms of sound insulation and heat insulation is relatively weak. Steel itself is a good heat conductor, which means that it cannot effectively isolate the change of external temperature, resulting in the indoor temperature being easily affected by the outside and fluctuating. In winter, more energy is required indoors to maintain a suitable temperature; while in summer, the indoor may become stuffy due to the invasion of external high temperature. This high energy consumption not only increases the living cost, but also goes against the concept of energy conservation, emission reduction and green building advocated in today's society. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems of easy appearance of dents on the surface and poor energy-saving effect in the prior art, and to propose a heat-insulating and energy-saving steel structure wall.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a heat-insulating and energy-saving steel structure wall, including a steel plate. Two reinforcing steel frames are symmetrically and fixedly connected to the inner side of the steel plate. A plate body is installed between the two reinforcing steel frames. A fixed reinforcing steel bar is fixedly connected to the inner side of the steel plate. One end of the fixed reinforcing steel bar is fixedly connected to the side wall of the plate body. A backing plate is installed on the side wall of the steel plate. The backing plate is sleeved on the outer surface of the fixed reinforcing steel bar. And a spring is arranged on one side of the backing plate. The spring is sleeved on the outer surface of the fixed reinforcing steel bar. The fixed reinforcing steel bar is lapped on the reinforcing steel frame. One end of the spring abuts against the reinforcing steel frame. A heat-insulating board is installed on the inner side of the plate body.

[0007] Preferably, a cavity is provided on the inner wall of the steel plate, and an anti-corrosion coating is applied on the outer surface of the steel plate.

[0008] Preferably, glass wool layers are fixedly connected to both sides of the plate body, and the side walls of the glass wool layers abut against the steel bar frame.

[0009] Preferably, the thickness of the glass wool layer is the same as that of the plate body.

[0010] Preferably, the insulation board includes a fireproof board, and a polycarbonate board is compound-connected to the inner side of the fireproof board.

[0011] Preferably, the thickness of the polycarbonate board is three times that of the fireproof board.

[0012] Preferably, a sound-absorbing cavity is provided on the inner side of the polycarbonate board.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] 1. In the present utility model, when the steel plate is subjected to extrusion, the fixed steel bars disperse stress, protecting the steel plate from local stress concentration. The spring absorbs impact energy, slowing down the direct action on the plate body, enhancing the self-recovery ability and stability of the structure. The glass wool layer has low thermal conductivity for heat insulation and energy conservation, and its fiber structure absorbs sound and reduces noise, creating a quiet environment. The cavity not only expands space utilization but also enhances the sound insulation effect through multiple attenuation mechanisms, optimizing the building performance.

[0015] 2.

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0023] Embodiment 1: As Figure 1 - Figure 3 shown, the present utility model provides a heat-insulating and energy-saving steel structure wall, which includes a steel plate 1. Two steel bar frames 2 are symmetrically and fixedly connected to the inner side of the steel plate 1. A plate body 3 is installed between the two steel bar frames 2. A fixed steel bar 6 is fixedly connected to the inner side of the steel plate 1. One end of the fixed steel bar 6 is fixedly connected to the side wall of the plate body 3. A base plate 9 is installed on the side wall of the steel plate 1. The base plate 9 is sleeved on the outer surface of the fixed steel bar 6. And a spring 10 is arranged on one side of the base plate 9. The spring 10 is sleeved on the outer surface of the fixed steel bar 6. The fixed steel bar 6 is lapped on the steel bar frame 2. One end of the spring 10 abuts against the steel bar frame 2. A thermal insulation board 4 is installed on the inner side of the plate body 3.

[0024] The following specifically describes the specific settings and functions of this embodiment. When the steel plate 1 is used as an external protective layer or a load-bearing structure and is externally squeezed, the fixed steel bar 6, through its strong tensile and compressive capabilities, evenly disperses and transmits the extrusion force to the plate body 3, thereby effectively reducing the local stress concentration phenomenon of the steel plate 1.

[0025] During this process, the spring 10, as an elastic element, can deform and store energy when subjected to an external force, and can gradually return to its original state when the external force disappears. Therefore, when the steel plate 1 is squeezed, the spring 10 can absorb part of the impact energy, slow down the direct action of the extrusion force on the plate body 3, thereby protecting the plate body 3 from being damaged by instant high stress. At the same time, the energy storage characteristic of the spring 10 also means that after the impact, the system can partially or completely return to its original state, improving the self-recovery ability and overall stability of the structure.

[0026] The glass wool layer 7 has an extremely low thermal conductivity, which can effectively prevent the transfer of heat between the inside and outside of the building, thereby maintaining the stability of the indoor temperature, reducing the energy consumption of equipment such as air conditioners and heaters, and improving the energy efficiency of the building. In addition, the glass wool also has good sound absorption performance. Its fibrous structure can absorb and dissipate sound wave energy, reduce the propagation and reflection of noise inside the building, and create a more peaceful and comfortable environment for the occupants.

[0027] As a part of the building structure, the cavity 5 not only provides additional possibilities for space utilization in the building, but also further enhances the sound insulation effect of the building.

[0028] Example 2: As Figure 2 and Figure 4 shown, a cavity 5 is provided on the inner wall of the steel plate 1, and an anti-corrosion coating 8 is applied on the outer surface of the steel plate 1. Glass wool layers 7 are fixedly connected to both sides of the plate body 3, and the side walls of the glass wool layers 7 are abutted against the steel bar frame 2. The thickness of the glass wool layer 7 is the same as the thickness of the plate body 3. The insulation board 4 includes a fireproof board 12, and a polycarbonate board 13 is compound-connected to the inner side of the fireproof board 12. The thickness of the polycarbonate board 13 is three times the thickness of the fireproof board 12. A sound absorption cavity 11 is provided on the inner side of the polycarbonate board 13.

[0029] The effect achieved by the entire embodiment is that an anti-corrosion coating 8 is applied on the outer surface of the steel plate 1. It not only has excellent isolation effect, can effectively isolate moisture, oxygen and various electrolytes in the air, reduce the occurrence of electrochemical corrosion, but also has excellent weather resistance and can maintain a stable protection effect under long-term sunlight and rain.

[0030] The fireproof board 12 is made of rock wool. With its unique fibrous structure, rock wool not only has excellent sound insulation performance and can effectively reduce noise transmission. At the same time, rock wool also has excellent fireproof performance. It will not burn even at high temperatures and can effectively isolate heat transmission, providing a solid guarantee for building safety. Rock wool not only has excellent performance, but also has good environmental protection. It does not contain harmful substances during the production process and can be recycled, meeting the concept of modern green buildings. In addition, the rock wool board also has good compressive strength and tensile strength, and can meet the strength requirements of different building structures. The polycarbonate board 13 uses polycarbonate resin as the main base material, and by adding reinforcing materials such as glass fiber, the mechanical properties and thermal stability of the board are significantly improved. The polycarbonate board 13 is not only light in weight, convenient for transportation and installation, but also high in strength and can withstand large external force impacts without being easily damaged. In terms of corrosion resistance, the polycarbonate board 13 has excellent chemical stability and can resist the erosion of chemical substances such as acids and alkalis.

[0031] Usage method and working principle of this device: The fixing steel bars 6 can play a role in reinforcement. When the steel plate 1 is extruded by the outer wall, it will simultaneously extrude the fixing steel bars 6, so that the fixing steel bars 6 transfer the received extrusion force to the plate body 3. During this process, the spring 10 plays a buffering role, can store energy, and at the same time can prevent the strong extrusion force from directly acting on the plate body 3.

[0032] The glass wool layer 7, due to its low thermal conductivity, excellent heat insulation and sound absorption performance, and strong corrosion resistance, can effectively isolate the high temperature or low temperature outside, reduce the energy loss, thereby improving the energy efficiency of the building and achieving the effect of energy-saving and heat preservation. In addition, the existence of the cavity 5 further enhances the sound insulation effect.

[0033] The anti-corrosion coating 8 coated on the outer surface of the steel plate 1 can form a protective film, effectively isolate the moisture and electrolytes in the environment, thereby delaying the corrosion process of the steel structure and increasing the service life of the steel plate 1. At the same time, the fireproof board 12 is made of rock wool, which not only has significant sound insulation and fireproof effects, but also the polycarbonate board 13, this kind of board made of polycarbonate resin and glass fiber reinforced material, also has multiple advantages such as light weight, high strength, corrosion resistance, and fireproof.

[0034] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
