Description

Technical Field

[0001] The utility model relates to the technical field of light steel wall, in particular to a light steel wall thermal insulation unit structure. Background Art

[0002] The wall skeleton mainly includes load-bearing walls and non-load-bearing walls, which mainly play the role of enclosure and separation of space. The wall of the load-bearing structure building is a combination of load-bearing and enclosure. The function of the wall of the skeleton structure system building is to enclose and separate space. The wall must have sufficient strength and stability, and have the ability of heat preservation, heat insulation, sound insulation, fire prevention and waterproofing. Light steel keel is a new type of building material. With the development of my country's modernization construction, light steel keel is widely used in hotels, terminal buildings, bus stations, stations, playgrounds, shopping malls, factories, office buildings, old building renovation, interior decoration settings, ceilings and other places.

In view of the problem that the prior art lacks effective fixation of thermal insulation and sound insulation materials in light steel walls and that light steel walls are susceptible to moisture or corrosion in humid environments, the utility model provides a corrosion-resistant, heat-insulating, and thermally insulating light steel wall. The utility model includes an inner wall panel, an outer wall panel, a vertical keel vertically arranged between the inner wall panel and the outer wall panel, and two top and bottom keels arranged between the inner wall panel and the outer wall panel, the two top and bottom keels are respectively arranged at the top and bottom of the inner wall panel and the outer wall panel, and glass wool is filled between the inner wall panel and the outer wall panel. The surfaces of the inner wall panel and the outer wall panel are coated with an aluminum-zinc coating, and a positioning strip for fixing the glass wool is arranged between the two top and bottom keels.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 The utility model provides a light steel wall insulation unit structure, including a light steel keel 1, a sound insulation layer 101, a first OSB tension plate 2, a second OSB tension plate 201, a gypsum board 3, a glass wool layer 301, an exterior wall board 4, moisture-proof breathing paper 401, a wooden square 5, an extruded board 501, a putty layer 6 and a latex paint layer 601.

[0023] The sound insulation layer 101 is filled in the light steel keel 1, and the sound insulation layer 101 is made of rock wool. Rock wool originated in Hawaii. The production process of rock wool actually simulates the natural process of Hawaiian volcanic eruption. Rock wool products are made of high-quality basalt, dolomite, etc. as the main raw materials. After being melted at a high temperature of more than 1450°C, they are centrifuged into fibers by an internationally advanced four-axis centrifuge at high speed. At the same time, a certain amount of adhesive, dust-proof oil, and water-repellent are sprayed in, and then collected by a cotton collector, and solidified and cut after the pendulum method and three-dimensional cotton laying to form rock wool products of different specifications and uses. Rock wool board has good thermal insulation and heat insulation properties, and has the characteristics of light weight, low thermal conductivity, heat absorption, and non-combustibility. The sound insulation layer 101 made of rock wool has good thermal insulation and fire resistance, thereby improving the use experience of the staff.

The first OSB tension board 2 and the second OSB tension board 201 are respectively arranged on two opposite side walls of the light steel keel 1. OSB board is a directional structural board made of small-diameter wood, thinning wood, and wood core, processed into long shavings by special equipment, and processed by degreasing, drying, gluing, directional paving, hot pressing and other processes. It has extraordinary ease of processing and moisture resistance. The first OSB tension board 2 and the second OSB tension board 201 cooperate with each other to reduce the probability of water ingress into the room.

[0025] The gypsum board 3 is a plate-like structure, and the gypsum board 3 is arranged on the side wall of the first OSB tension board 2. The glass wool layer 301 is arranged on the side wall of the second OSB tension board 201 to improve the thermal insulation performance of the wall. The exterior wall panel 4 is a plate-like structure, and the exterior wall panel 4 is arranged on the side wall of the glass wool layer 301 away from the light steel keel 1.

[0026] The moisture-proof breathing paper 401 is arranged between the glass wool layer 301 and the exterior wall panel 4. The moisture-proof breathing paper 401 has the characteristics of one-way air permeability and water-tightness, thereby further improving the waterproof performance of the wall and reducing the probability of indoor moisture accumulation, thereby improving the living experience of the house.

[0027] The wooden square 5 is arranged between the moisture-proof breathing paper 401 and the outer wall board 4, and the wooden square 5 is made of pine wood. Pine wood has the characteristics of being hard, rot-resistant, water-resistant, and not easy to crack, and is cheap. The wooden square 5 made of pine wood has good stability.

[0028] The extruded board 501 is a plate-like structure, and the extruded board 501 is arranged between the exterior wall panel 4 and the moisture-proof breathing paper 401. The full name of the extruded polystyrene board is extruded polystyrene foam board, abbreviated as extruded board 501, also known as XPS board, extruded polystyrene board. The extruded board 501 is a rigid foam plastic board that is assisted by polystyrene resin and polymer, and injected with a catalyst while heating and mixing, and then extruded to produce continuous closed-cell foaming. The interior is an independent closed bubble structure, which is an environmentally friendly thermal insulation material with excellent properties such as high pressure resistance, low water absorption, moisture resistance, airtightness, light weight, corrosion resistance, super anti-aging (almost no aging after long-term use), and low thermal conductivity. The extruded board 501 arranged between the exterior wall panel 4 and the moisture-proof breathing paper 401 further enhances the moisture-proof ability of the wall, thereby reducing the probability of water ingress into the putty layer 6, thereby improving the user experience of the staff.

[0029] The putty layer 6 is arranged on the side wall of the gypsum board 3 away from the first OSB tension board 2 , and the latex paint layer 601 is arranged on the side wall of the putty layer 6 .
