Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a light steel building insulation layer construction structure. Background Art

[0002] Light steel structure is a young and vital steel structure system, which has been widely used in general construction sites, agriculture, commerce, service buildings, such as office buildings, warehouses, stadiums, entertainment, tourism buildings and low-rise and multi-story residential buildings. Insulation is a scientific and efficient energy-saving technical measure to slow down the speed of heat dissipation and conduction. Insulation, keeping warm in winter and insulating in summer, is called real insulation. It is the ability of traditional and new energy-saving decorative panels or products for masonry walls or external fence structures to prevent heat loss in winter, block external heat in summer, and maintain room temperature stability. It usually refers to the ability of the enclosure structure (including roofs, exterior walls, doors and windows, etc.) to prevent heat transfer from indoors to outdoors in winter and conduct heat from outside to inside in summer, so as to maintain an appropriate temperature indoors.

[0003] After searching, the Chinese patent publication number CN214169645U discloses a double-layer light steel building insulation structure, including a main body, a connecting plate, a connecting block, a first support plate, a spring, a second support plate, an insulation layer, an insulation cavity and a rock wool layer. The main body is fixedly installed with a connecting plate inside, the surface of the connecting plate is fixedly installed with a connecting block, the inside of the connecting plate is fixedly installed with a first support plate, the surface of the first support plate is fixedly installed with a spring, the bottom of the spring is fixedly installed with a second support plate, the surface of the second support plate is fixedly installed with an insulation layer, the inside of the connecting plate is provided with an insulation cavity, and the inside of the connecting plate is fixedly installed with a rock wool layer. The above patent has the following shortcomings: Although the patent can achieve the effect of heat insulation stripes through the rock wool layer arranged inside, the spring arranged inside cannot play a buffering role, so the safety of the building structure needs to be improved. In view of this, we propose a light steel building insulation layer construction structure. Utility Model Content

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.

[0023] like Figure 1-3 As shown, a light steel building insulation layer construction structure includes a fiber cement exterior wall hanging board 1 and a concrete layer 3;

[0024] An air pressure buffer structure 2 is provided between the fiber cement exterior wall hanging board 1 and the concrete layer 3;

[0025] The air pressure buffer structure 2 includes a fixed block 21, an inner cavity 22, a first sliding column 23, and a second sliding column 24;

[0026] The inner cavity 22 is opened inside the fixed block 21, and high-pressure gas is arranged inside the inner cavity 22. The bottom of the first sliding column 23 is fixedly connected to the top of the fiber cement exterior wall hanging panel 1, and the top of the first sliding column 23 slides through the inner cavity 22 and is fixedly connected to the limiting plate 25. The top of the second sliding column 24 is fixedly connected to the bottom of the concrete layer 3, and the bottom end of the second sliding column 24 slides through the inner cavity 22 and is fixedly connected to the limiting plate 25.

[0027] Specifically, the limiting plate 25 is provided to prevent the first sliding post 23 and the second sliding post 24 from being separated from the fixing block 21 .

[0028] like Figure 3 As shown, the left and right sides of the fixed block 21 are fixedly connected with sliding grooves 26 , and the interior of the sliding grooves 26 is slidably connected with sliding blocks 27 .

[0029] Specifically, the movement of the slider 27 is limited by providing the slide groove 26 .

[0030] like Figure 3As shown, the top of the concrete layer 3 is hinged to the slider 27 via a first connecting rod 28 , and the bottom of the fiber cement exterior wall hanging board 1 is hinged to the slider 27 via a second connecting rod 29 . The first connecting rod 28 is arranged on the side of the second connecting rod 29 .

[0031] like Figure 1 As shown, a hot-dip galvanized welded steel wire mesh 4 is fixedly connected to the bottom of the concrete layer 3. The steel wire diameter of the hot-dip galvanized welded steel wire mesh 4 is 0.8 mm, and the mesh size is 12.5×12.5 mm.

[0032] Specifically, the hot-dip galvanized welded steel wire mesh 4 can effectively prevent the inorganic fiber spray layer 5 from cracking.
