Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a thick paper-faced gypsum board roof interior surface system and its construction method. Background Technology

[0002] Paper-faced gypsum board is a type of board made from building gypsum as the main raw material, with appropriate additives and fibers mixed in as the core, and special paper as the facing. Paper-faced gypsum board is characterized by its light weight, sound insulation, heat insulation, strong processing performance, and simple construction method. Paper-faced gypsum board can be divided into four categories: ordinary, water-resistant, fire-resistant, and moisture-proof.

[0003] Thick paper-faced gypsum board has many applications in the construction field due to its easy construction, light weight, sound insulation, and heat insulation properties. The methods of treating the wall surface by laying tiles or latex paint are different. Tiles are expensive, the laying process is more complicated, and problems such as hollowing and chipping are easy to occur. The production of latex paint has high requirements for the flatness and roughness of the wall surface, and multiple processes need to be carried out on the wall surface in the latex paint spraying cavity.

[0004] Therefore, there is a need to provide a thick paper-faced gypsum board roofing surface system and its construction method. The thick paper-faced gypsum board is used as the decorative panel. After the surface of the vertical wall is treated, the thick paper-faced gypsum board is installed. The lightweight aluminum profile is used to provide the installation framework for the interior ceiling, so that the thick paper-faced gypsum board can be installed easily and stably. Summary of the Invention

[0005] To address the existing technical problems, this application provides a thick paper-faced gypsum board roof interior surface system and its construction method.

[0006] This application provides a thick gypsum board roofing interior surface system and its construction method, which adopts the following technical solution: A thick gypsum board roofing interior surface system and its construction method include a galvanized square tube frame. Multiple first thick gypsum boards are arranged on the right side of the galvanized square tube frame. Structural layers are arranged on both sides of the galvanized square tube frame. The structural layers include a concrete leveling layer poured onto the surface of the galvanized square tube frame. An adhesive layer is applied to the left side of the concrete leveling layer. A wall tile layer is laid to the left side of the adhesive layer. A waterproof layer is applied to the right side of the galvanized square tube frame. A wire mesh plaster layer is applied to the right side of the waterproof layer. A magnesium oxide board is installed to the right side of the wire mesh plaster layer. A second thick gypsum board is fixedly connected to the right side of the magnesium oxide board by nail guns. Multiple sets of lifting components are arranged on the top of the first thick gypsum board. Multiple sets of connecting components are arranged on the surface of the aluminum crossbeams. Multiple aluminum crossbeams are arranged on the top of the first thick gypsum board.

[0007] Preferably, the hoisting assembly includes a clamp fitted onto the surface of an aluminum beam, a hoisting screw rod at the top of the clamp, the top of the hoisting screw rod being fixed to the interior ceiling wall by a nail gun, and a threaded sleeve being threadedly connected to the bottom of the hoisting screw rod surface, the bottom of the threaded sleeve being tightly fitted to the top of the clamp.

[0008] Preferably, a threaded rotating rod is rotatably connected to the top of the left side of the clamp's inner cavity, the right end of the threaded rotating rod extends through to the right side of the clamp, and a pressing wedge is threadedly connected to the surface of the threaded rotating rod. The inner cavity of the clamp is provided with a liftable wedge-shaped pressure plate.

[0009] Preferably, a rectangular groove adapted to the wedge-shaped pressure plate is provided on the right side of the clamp. A spring guide post is fixedly connected to the inner cavity of the rectangular groove. The wedge-shaped pressure plate is slidably connected to the surface of the spring guide post. A reset spring is sleeved on the surface of the spring guide post. The top and bottom ends of the reset spring are welded to the wedge-shaped pressure plate and the rectangular groove, respectively.

[0010] By adopting the above technical solution, and through the setting of the hoisting components, the use of positioning slots and threaded sleeves allows the clamps to be quickly fixed to the bottom end of the hoisting screw. At the same time, through the use of threaded rotating rods, extrusion blocks and wedge-shaped pressure plates, downward extrusion force is generated on the aluminum crossbeam, thereby allowing the aluminum crossbeam to be installed more stably in the inner cavity of the clamps.

[0011] Preferably, the connecting assembly includes a longitudinal aluminum plate located on top of the first thick paper-faced gypsum board, and a connecting plate is slidably connected to the inner cavity of the longitudinal aluminum plate, the connecting plate engaging with the aluminum crossbeam.

[0012] Preferably, a positioning bolt is provided through the top of the connecting plate, and multiple positioning holes that are compatible with the positioning bolt are provided at the top and bottom of the aluminum crossbeam.

[0013] By adopting the above technical solution and setting the connecting components, including the longitudinal aluminum plate, the overall stability of the first thick paper-faced gypsum board installation structure is improved. At the same time, with the cooperation of positioning bolts and positioning holes, the longitudinal aluminum plate is connected to the aluminum crossbeam, thereby further reinforcing the structure formed by the aluminum crossbeam and the longitudinal aluminum plate.

[0014] Preferably, the bottom of the galvanized square tube frame is welded with embedded plates, which are embedded in the interior floor wall. The top of the galvanized square tube frame is provided with multiple expansion bolts that penetrate into the interior ceiling wall.

[0015] Preferably, a stiffening plate is fixedly connected to the top of the inner cavity of the clamp, and a limiting groove adapted to the stiffening plate is opened on the top of the extrusion block.

[0016] By adopting the above technical solution, the combination of stiffening plate and limiting slide groove improves the deformation resistance of the clamp cavity and limits and guides the extrusion block, preventing the extrusion block from rotating during horizontal displacement.

[0017] Preferably, the concrete leveling layer has pre-embedded tie bars inside.

[0018] A thick paper-faced gypsum board roofing interior surface system, the construction method of which is as follows: First, the user constructs a partition wall frame by erecting a galvanized square tube frame. Then, the partition wall frame is filled with a concrete leveling layer, and the two sides of the galvanized square tube frame are leveled. At the same time, the bottom and top of the galvanized square tube frame are fixed to the interior wall by using embedded plates and expansion bolts. Next, the user applies an adhesive layer to the left side of the galvanized square tube frame and lays a layer of wall tiles on the surface of the adhesive layer. A waterproof layer is applied to the right side of the galvanized square tube frame. After the waterproof layer solidifies, a wire mesh plaster layer is applied behind it. A magnesium oxide board is installed on the right side of the wire mesh plaster layer, and a second thick paper-faced gypsum board is fixed to the right side of the magnesium oxide board using nail guns. 2. Based on the ceiling area and installation spacing, install the hoisting screw rods onto the interior ceiling wall using a nail gun. Then, install the clamps on the surface of the hoisting screw rods, engage the positioning slots at the bottom of the hoisting screw rod surface, and tighten the threaded sleeves to compress the clamps, thus fixing them in place. Next, install the aluminum beams, inserting them into the inner cavity of the clamps and adjusting them to the appropriate positions. Tighten the threaded rotating rods, which, through their threads, drive the pressing wedges to slide within the clamps. As the pressing wedges slide within the clamps, they are pressed together by the inclined surfaces at their bottom and the top of the wedge-shaped pressure plate, causing the wedge-shaped pressure plate to move downwards and press and fix the aluminum beams. 3. After the aluminum crossbeam is erected, the user will clamp the connecting plate onto the surface of the aluminum crossbeam, slide the connecting plate left and right to the appropriate position, and then turn the positioning bolt into the positioning hole to limit and fix the position of the connecting plate. Insert the longitudinal aluminum plate into the bottom of the longitudinally fixed connecting plate so that the longitudinal aluminum plate can be clamped and fixed. Lift the cut first thick paper-faced gypsum board to the bottom of the longitudinal aluminum plate, and fix the first thick paper-faced gypsum board and the longitudinal aluminum plate by tapping. Fourth, the end user should apply rust inhibitor to the hardware on the surface of the first and second thick gypsum boards, and then level the surface of the first and second thick gypsum boards with putty.

[0019] In summary, this application includes the following beneficial technical effects: This invention provides a stable and waterproof wall surface for the second-thickness gypsum board through the combined use of a galvanized square tube frame and a structural layer. Furthermore, the first-thickness gypsum board is hoisted and fixed using a combination of hoisting and connecting components, providing a structurally stable and lightweight installation framework. This achieves the goals of simple construction, low construction cost, and stable installation structure. It solves the problems associated with using tiles or latex paint for wall treatment, which are expensive, cumbersome to install, and prone to problems like hollow spots and chipping. Latex paint production, on the other hand, requires a high degree of flatness and roughness of the wall surface, necessitating multiple processes in the paint spraying chamber.

Furthermore, through the combined use of hoisting components 5 and connecting components 6, the first thick gypsum board 2 is hoisted and fixed, providing a structurally stable and lightweight installation framework for it. This achieves the goals of simple construction, low construction cost, and stable installation structure. It solves the problems associated with using tiles or latex paint for wall treatment. Tiles are expensive, the laying process is cumbersome, and problems such as hollow spots and chipping are common. Latex paint production, on the other hand, requires a high degree of flatness and roughness of the wall surface, necessitating multiple processes in the latex paint spraying area.
