Description

Technical Field

[0001] The invention relates to an XN light steel keel roof panel and belongs to the technical field of assembled building materials. Background Art

[0002] Currently, people in grasslands of some countries and mountainous areas of some Southeast Asian countries are eager to own a permanent, self-built house. However, due to the difficulty in obtaining steel and concrete in these grasslands and mountainous areas, or the high transportation costs of obtaining these building materials, as well as the lack of construction equipment and construction technology in these countries, it is difficult for people to obtain a low-cost, simple, and permanent living house.

[0003] In the grassland areas of some countries and some Southeast Asian countries, solving people's problem of obtaining low-cost fixed housing (in batches) is a technical problem that people have always been eager to solve.

[0004] Prefabricated buildings generally refer to buildings that have transferred a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods.

[0005] Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc. Because they adopt standardized design, factory production, assembly construction, information-based logistics management, and intelligent applications, they have become the representative of modern industrialized production methods.

[0006] In addition, in the existing technology, the existing prefabricated roof panels are mainly prestressed hollow panels and rock wool sandwich color steel tiles; although the prestressed hollow panels have sound insulation effects, their thermal insulation performance is poor and their weight is relatively high; the waterproof performance of rock wool sandwich color steel tiles is completely dependent on metal tiles. Once water seeps into the joints of the metal tiles, the rock wool core material will lose its thermal insulation performance after absorbing water, and will reduce the durability and safety of the panels; moreover, rock wool sandwich color steel tiles have low strength and weak wind resistance, which can easily cause safety accidents. Summary of the Invention

[0007] In view of the problems currently existing in the prior art, the purpose of the present invention is to provide an XN light steel keel roof panel.

[0008] An XN light steel keel roof panel; the XN light steel keel roof panel comprises the following 9 layers, which are pressed together in sequence:

[0009] Layer 1, the first M15 cement mortar layer;

[0010] The second layer, the first alkali-resistant fiber mesh cloth,

[0011] The third layer is the first high-density rubber powder particle slurry;

[0012] The 4th layer, the second alkali-resistant fiber mesh cloth,

[0013] The fifth layer is a molded polystyrene board 1003. The molded polystyrene board is grooved on both sides. High-density rubber powder granular mortar is added to the grooves to form reinforcing ribs, increasing the strength of the wallboard. Furthermore, the molded polystyrene board 1003 also contains a C-shaped light steel through-keel. This through-keel not only serves to enhance the hardness (strength) of the roof panel, but can also be used to hang heavy objects externally. When heavy objects are planned to be hung externally, expansion bolts are installed on the keel.

[0014] The 6th layer, the third alkali-resistant fiber mesh cloth,

[0015] The 7th layer, the second highest density rubber powder particle slurry,

[0016] The 8th layer, the fourth alkali-resistant fiber mesh cloth,

[0017] 9th layer, second M15 cement mortar layer;

[0018] Here, the high-density rubber powder particle slurry is preferably a rubber powder polystyrene particle slurry with a bulk density of 450 grams (g) or more.

[0019] The present invention provides an XN light steel keel roof panel. Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention has built-in heat preservation and sound insulation core materials, and has good heat preservation and sound insulation effects.

[0021] 2. The present invention contains a through-type galvanized light steel keel, which can be connected to the steel beam / steel purlin through drill thread to form an integral roof. The surface is a waterproof mortar layer, which forms a double waterproof system of the roof with the upper metal tile.

[0022] 3. As a building material for prefabricated houses, the present invention processes and manufactures building components and accessories in the factory and assembles and installs them on site. It has standardized design, unified factory production, and on-site construction, and has the characteristics of fast construction speed, convenient construction, and low cost.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The accompanying drawings are for illustrating the present invention, but not for limiting the present invention.

[0029] Figure 1 This is a schematic diagram of the structure of an assembled integrated house of the present invention. In the figure, 01 is the foundation, 02 is the ground, 03 is the steel structure, 04 is the exterior finishing layer of the exterior wall, 05 is the wall of the exterior wall, 06 is the interior finishing layer of the exterior wall, 07 is the interior partition wall, 08 is the door and window, 09 is the indoor ceiling, 10 is the roof insulation layer, and 11 is the roof waterproof finishing layer; Figure 1 As shown, an assembled integrated house includes a foundation part 01, a ground 02, a steel structure part 03, an exterior wall exterior finishing layer 04, an exterior wall body 05, and an exterior wall interior finishing layer 06: 07 is an interior partition wall, 08 is a door and window, 09 is an indoor ceiling, 10 is a roof insulation layer, 11 is a roof waterproof finishing layer, etc., wherein,

[0030] (1) Foundation part 01: as the supporting structure of the whole house, it ensures the stability and safety of the house; here, the foundation part is the screw pile foundation 013, the foundation short column 014 and its steel platform 015. Figure 2 As shown, Figure 2 This is a structural diagram of the screw pile and its short column, foundation short column 014, and steel platform 015. Figure 2 (a) is a schematic diagram of a screw pile structure, which consists of a screw rod, screw ears, and a mounting cap (fixed and welded, or custom-molded). The screw pile structure is shaped like a large, sharp nail with screw ears, allowing for quick and easy driving into the ground by manpower or machine. Figure 2 (b) is a schematic diagram of the short column structure, as shown in the figure, the short column also has a corresponding mounting plate and its mounting hole; Figure 2 (c) is a schematic diagram of the screw pile foundation 013 structure consisting of a screw pile and its short columns. Figure 2 (a) Figure 2 (b) Installed by bolt combination is as follows Figure 2 Furthermore, in order to increase the supporting force of the screw pile, the screw piles of the present invention can be combined in multiple pieces according to the angle, such as Figure 2 As shown in (d), Figure 2 (d) is a schematic diagram of a large spiral pile and its short column structure, constructed by combining multiple such spiral piles. Spiral pile foundations and large spiral pile foundations can be used in combination (generally, the center spiral pile is driven vertically into the ground, while the corner spiral piles can be combined to enhance the overall stability of the house by using multiple (e.g., three) large spiral piles driven obliquely into the ground, depending on geological conditions). Figure 2 (e) is a schematic diagram of the structure of the basic short column 014 of the present invention. Figure 2As shown in (e), the foundation short column 014 can be a galvanized steel pipe short column with both ends indented toward the middle to facilitate the connection between the foundation short column and the short column, steel column, etc., and the foundation short column 014 is provided with a bolt mounting hole; the steel platform can use square steel and its accessories (for supporting the floor load-bearing plate), and the second steel column 0321 and the foundation short column 014 are first connected by socketing and then connected by bolts; the square steel of the steel platform is also connected to the foundation short column 014 by bolts; further, after the second steel column 0321 and the foundation short column 014 are connected by socketing, an L-shaped angle iron can be first used as a gasket and then connected by bolts, the square steel of the steel platform is connected to the foundation short column 014 by bolts, the L-shaped angle iron is connected to the foundation short column 014 by bolts, and the L-shaped angle iron is connected to the square steel of the steel platform by bolts. Because the steel structure has multiple steel columns (correspondingly, multiple different foundation short columns), the square steel of the multiple steel platforms is connected to the corresponding foundation short columns via bolts to form a steel platform. Furthermore, the second steel column 0321 is connected to the foundation short column 014 via bolts and L-shaped washers. The multiple foundation short columns (multiple steel columns) are connected to each other via square steel (at both ends), L-shaped washers, and bolts (the square steel of the steel platform is connected to the foundation short column 014 via bolts), forming a steel platform. Figure 2 (f) is a schematic diagram of the (partial) connection structure of the screw pile foundation, steel column, foundation short column, and steel platform.

[0031] The use of spiral pile foundation has the advantages of fast pile construction speed, saving construction time, low construction cost, easy installation, strong corrosion resistance, good environmental protection, high strength, high rigidity and strong stability. It is suitable for areas where concrete is scarce or transportation is inconvenient.

[0032] (2) Ground 02: Located above the foundation, it is the flat space for internal activities in the house. For comfortable use, tiles or wooden floors can be laid on the ground (forming the ground finishing layer 023) to decorate the house floor. Furthermore, XN floor bearing plates can be used, laid between the ground and the steel platform as the "ground", and then tiles or wooden floors can be laid on top of them to decorate the house floor.

[0033] (3) Steel structure part 03: It constitutes the skeleton of the house, provides overall stability and support, and is an important part of the house structure. The steel structure includes a second steel column 0321, a steel beam 033, a shear brace, a purlin 034, a connector 035, an overhang, etc. The second steel column 0321 has a hole, which is connected to the screw pile foundation 013 through bolts and a foundation short column 014. Furthermore, the second steel column 0321 has a hole, which is connected to the screw pile foundation 013 through bolts, a foundation short column, and an L-shaped angle iron. The steel structure steel beams 033 are connected horizontally to form a horizontal beam, vertically to form a longitudinal beam, and diagonally to form an oblique beam. In order to improve the stability of the house, a shear brace (using a steel beam) can also be installed between the two beams. (Multiple) second steel columns 0321 and (multiple) steel beams 033 form a fixed, connected, and compact spatial structure of the house. Purlins 034 can be galvanized and are installed on the steel beams 033 via connectors 035. Purlins 034 not only further tighten the steel beams to stabilize the structure, but also serve as the foundation for the roof insulation layer 10 and the waterproof finish layer 11. To facilitate roof drainage and protect the exterior walls, the steel structure 03 may also have overhangs. Connectors 035 are galvanized. The steel columns at the corners are connected to the diagonal beams, longitudinal beams, transverse beams and overhangs through the first galvanized connector 0351; the steel columns in the middle are connected to the diagonal beams, longitudinal beams, transverse beams and overhangs through the second galvanized connector 0352; the scissors braces between two (horizontal or longitudinal) beams are connected through the third galvanized connector 0353; the diagonal ridge beams, horizontal steel beams and their scissors braces are connected through the fourth galvanized connector 0354; the purlins are connected to the steel beams through the fifth galvanized connector 0355; the longitudinal beams, transverse beams and scissors braces are connected through the sixth galvanized connector 0356.

Figure 3 (f) is the sixth galvanized connector 0356. Figure 3 As shown, the first galvanized connector 0351, as Figure 3 As shown in (a), the steel columns used for corners are connected to the diagonal beams, longitudinal and transverse beams and eaves. The opening diameter is 18mm and M16 bolts are inserted. The second galvanized connector 0352, such as Figure 3As shown in (b), it is used to connect the steel column in the middle of the (exterior wall) with the inclined beam, longitudinal beam, horizontal beam and eaves. The opening diameter is 18mm and M16 bolts are inserted. The third galvanized connector 0353, as shown in Figure 3 As shown in (c), the connecting plate of the scissor brace between two beams (horizontal or vertical) has a hole diameter of 18mm and is threaded with M16 bolts. Figure 3 As shown in (d), it is used for connecting the roof ridge beam, horizontal beam and scissor support. The opening diameter is 18mm and M16 bolts are inserted. The fifth galvanized connector 0355, as shown in Figure 3 (e) is used to connect the purlin and the steel beam. The opening diameter is 18mm and M16 bolts are inserted. Figure 3 (f) is used for connecting longitudinal beams, transverse beams, and scissor braces. The opening diameter is 18mm, and M16 bolts are inserted. Using this steel structure offers advantages such as high strength, lighter weight than concrete columns, factory processing, and on-site assembly, resulting in high precision, high production efficiency, fast construction speed, short construction period, and excellent seismic resistance.
