Description

Technical Field

[0001] This invention relates to the field of building construction and wall construction, and in particular to a prefabricated fireproof and electromagnetic radiation-proof building interior wall structure and its construction method. Background Technology

[0002] Traditional construction methods are labor-intensive and relatively outdated, making it difficult to control construction quality and resulting in high energy consumption, which places a significant burden on the natural and social environment. Furthermore, construction sites are characterized by high labor intensity and numerous safety hazards, and the exposure to wind and sun during construction exacerbates the shortage of human resources, leading to a year-on-year increase in labor costs. The fire protection and electromagnetic radiation protection designs of prefabricated buildings differ from traditional buildings due to their material properties and the unique characteristics of factory-based assembly. Therefore, the design and safety of fire-resistant and electromagnetic radiation-protected prefabricated buildings face significant challenges.

[0003] Prefabricated interior walls, as key components of prefabricated buildings, offer advantages such as convenient construction and environmental friendliness, and play a role in altering layouts and increasing room size. However, when exposed to high temperatures such as fires, the strength and stability of the internal concrete of prefabricated interior walls can be affected. Without fire protection, the steel structure within prefabricated interior walls can reach temperatures exceeding 813K within 15 minutes, at which point its compressive strength and elasticity will decrease by 50%, potentially leading to building collapse. Furthermore, prolonged exposure to low-voltage electrical equipment such as computers, televisions, and stereos within the room can easily have adverse health effects. Furthermore, the electrical cabinets and related power distribution equipment inside the room, which consist of both strong and weak current circuits, will generate a large amount of electromagnetic interference. Due to the dense and compact equipment inside the room and the small protection distance, such electromagnetic interference signals may cause control system malfunctions and misoperations, seriously affecting the safe and reliable operation of electrical control equipment. In addition, in the common production of prefabricated interior walls, molds are used for casting and molding. The connection between molds is mostly fixed by bolts. When pouring concrete, the concrete squeezes the mold, which can easily cause the bolts at the mold connection points to loosen, resulting in the mold becoming loose and thus affecting the quality of interior wall production.

[0014] This invention also provides a construction method for a prefabricated fireproof and electromagnetic radiation-proof building interior wall structure, including the following specific steps: Step 1: Clean and install the edge mold and movable mold, apply release agent, and initially plan the shape and size of the interior wall; Step 2: Install the prefabricated building interior wall sill. Place the sill mold at the standard line position. After confirming that the dimensions of the left and right ends are correct, fix the clamp with magnets. Note that rubber pads must be used inside the clamp. Step 3: Install stirrups and horizontal bars. Pass the top of the stirrup through the slot of the movable mold, and pass the bottom of the stirrup through the horizontal bar. Keep it at the same level as one of the side molds. Adjust the other side mold and stirrup together to make the dimensions of the horizontal bars extending outward from the left and right ends of the steel cage meet the design requirements. Step 4: Arrange reinforcing ribs. Reinforcing ribs are arranged on both sides of the inner door mold and on the right side of the side guard mold. Step 5: Lay a single layer of wire mesh with a mesh size of 2.5 mm and fix it inside the mold. Pay attention to the tightness of the wire mesh when fixing it. Step Six: Pouring and Vibration.

Otherwise, use a trowel to smooth the concrete and bury it. At the same time, the curing time is 8-16 hours. The concrete strength after leaving the kiln should not be less than 15 MPa. The curing time and concrete strength must be carried out in accordance with the relevant safety manual. Step 8: Lay a single layer of wire mesh with a aperture of 2.5 mm on both sides of the inner wall surface, and fix the wire mesh with expansion bolts to ensure its stability. Pay attention to the tightness of the wire mesh when fixing it. Step 9: Lay radiation-proof mortar on both sides of the interior wall and smooth the surface to ensure a flat interior wall surface; Step 10: Check the surface and dimensions of the interior walls. Once you are sure they are correct, lift and remove all the formwork and clean the interior wall surface.

[0015] The technical effects and advantages of this invention are as follows: (1) The present invention utilizes a combination of stirrups, horizontal bars, reinforcing bars, multi-layer wire mesh and concrete layers. By fixing stirrups, horizontal bars and reinforcing bars between multiple edge molds and movable molds, and fixing wire mesh on the edge molds and movable molds, fireproof concrete is poured into the inner cavity of the edge molds and movable molds. Multi-layer wire mesh is used to shield electromagnetic fields, and the concrete layer plays a fireproof role, thereby improving the fireproof and electromagnetic shielding performance of the prefabricated interior wall. (2) The present invention utilizes the combination of mounting base, bolt one, threaded hole, mounting tube, movable rod, fixed base and bolt two. By moving the fixed block two to the mounting hole position, rotating and tightening bolt two so that its bottom is threadedly connected to the mounting hole, the fixed base is fixed on the upper surface of one end of the lower side mold. Then, the mounting tube and movable rod are rotated, and one end of the movable rod slides in the inner cavity of the mounting tube to adjust the position of the mounting base and fixed block one at the top of the mounting tube so that the fixed block one moves to the position of the corresponding threaded hole. The bolt one is rotated and tightened, and one end of it is threadedly connected to the inner cavity of the threaded hole, thus fixing the mounting base and fixed block one on one side mold. This forms a triangular structure between the mounting tube, movable rod and the two side molds, improving the connection strength between the side molds. (3) The present invention utilizes a combination of mounting base, positioning rod, positioning hole and compression spring. By moving the mounting base, the bottom of the positioning rod is slidably inserted into the inner cavity of the positioning hole. The limiting block slides with the positioning rod in the inner cavity of the sleeve, squeezing the compression spring. When the positioning rod slides upward, it drives the limiting block to compress and deform the compression spring. Furthermore, the elasticity of the compression spring is used to push the positioning rod downward, ensuring that the bottom of the positioning rod is stably inserted into the inner cavity of the positioning hole, which facilitates the positioning and installation of the side flange mold and the bottom flange mold.

[0027] This invention provides, for example Figure 1-9 The prefabricated fireproof and electromagnetic radiation-proof building interior wall structure shown includes multiple edge molds 1, which form a U-shaped frame. An inner door mold 2 is set in the inner cavity of the edge mold 1 and is U-shaped to form a door frame structure on the interior wall. A movable mold 3 is set at the top of the edge mold 1 and is used to cooperate with the edge mold 1 to form an interior wall casting template. The movable mold 3 and the multiple edge molds 1 form a closed interior wall frame. Stirrups 4 are set in the inner cavity of the movable mold 3. Horizontal bars 5 are set between the movable mold 3 and the edge mold 1. Reinforcing bars 6 are set in the inner cavity of the edge mold 1. By fixing the multiple stirrups 4, horizontal bars 5 and reinforcing bars 6 between the edge mold 1 and the movable mold 3, the main frame of the interior wall is formed, ensuring the stability of the assembly cavity. Furthermore, multiple wire meshes 7 are installed in the inner cavities of the edge mold 1 and the movable mold 3 to form an electromagnetic shielding structure inside the building's interior wall. By fixing at least three layers of wire meshes 7 in the inner cavity of the mold, the electromagnetic shielding effect of the wire meshes 7 is utilized to ensure the electromagnetic shielding performance of the interior wall. A concrete layer 8 is filled and installed in the inner cavities of the edge mold 1 and the movable mold 3 to form a fireproof structure inside the building's interior wall. By pouring the proportioned concrete into the inner cavities of the edge mold 1 and the movable mold 3, a concrete layer 8 is formed, which plays a fireproof role. Multiple support mechanisms 9 are arranged on both sides of the baffle mold 1. They are used to form a reinforcing structure on both sides of the baffle mold 1. The support mechanisms 9 form a triangular structure at the end of the multiple baffle molds 1, which plays a reinforcing role and ensures a stable connection between the baffle mold 1 and the movable mold 3. The positioning mechanism 10 is disposed between multiple edge molds 1. It is used to form a limiting and fixing structure at the connection position of multiple edge molds 1, improve the stability of edge mold 1, and facilitate the storage of support mechanism 9 on edge mold 1. Specifically, the support mechanism 9 includes a mounting base 91, a first fixing block 92, a first bolt 93, a threaded hole 94, a first fixing shaft 95, a mounting tube 96, a movable rod 97, a locking block 98, a locking groove 99, a second fixing shaft 910, a fixing base 911, a second fixing block 912, and a second bolt 913. The mounting base 91 is located at one end of the inner cavity of the retaining edge mold 1. The upper surface of the first fixing block 92 is fixedly connected to the mounting base 91, which is used to fix the mounting base 91 on multiple retaining edge molds 1. The mounting base 91 and the first fixing block 92 are located at... The flange mold 1 slides within its inner cavity, adjusting the position of the mounting base 91. Bolt 93 is slidably inserted into one side of the fixing block 92, securing the fixing block 92. Bolt 93 moves together with the mounting base 91 and the fixing block 92, fixing them within the inner cavity of the flange mold 1. Multiple threaded holes 94 are equidistantly arranged within multiple cavities of the flange mold 1, their inner cavities threadedly connected to one end of bolt 93. The multiple threaded holes 94 form... Two rows are arranged in the inner cavity of the retaining mold 1. The two ends of the fixed shaft 95 are rotatably connected to the mounting base 91. The top of the mounting tube 96 is fixedly connected to the middle of the fixed shaft 95. It is rotatably connected to the mounting base 91 through the fixed shaft 95. The mounting tube 96 is used to install the movable rod 97, which moves together with the movable rod 97. The top of the mounting tube 96 rotates around the fixed shaft 95 to adjust the angle of the mounting tube 96. The top of the movable rod 97 is slidably connected to the inner cavity of the mounting tube 96. One end of the rod 97 slides in the inner cavity of the mounting tube 96 to adjust the position of the movable rod 97. One end of the locking block 98 is fixedly connected to the outer wall of the top of the movable rod 97, which is used to limit the movement of the movable rod 97. The locking block 98 moves together with the movable rod 97. The locking groove 99 is provided on the mounting tube 96, and its inner cavity is slidably connected to the locking block 98. As the movable rod 97 slides in the inner cavity of the mounting tube 96, it drives the locking block 98 to slide in the inner cavity of the locking groove 99 to prevent the movable rod 97 from disengaging from the mounting tube 96. The fixed shaft 910 is fixedly inserted into the bottom of the movable rod 97. The fixed seat 911 is rotatably inserted into both ends of the fixed shaft 910, which is used to rotatably connect the fixed seat 911 to the bottom of the movable rod 97. The bottom of the movable rod 97 rotates around the fixed shaft 910, so that the movable rod 97 can rotate together with the mounting tube 96. The upper surface of the fixed block 912 is fixedly connected to the lower surface of the fixed seat 911. The fixed seat 911 is fixed to the lower edge mold 1 by the fixed block 912. The bolt 913 is threadedly inserted into one side of the fixed block 912, and one end of the bolt 913 is threadedly inserted into the top of one end of one edge mold 1. The top of one end of one edge mold 1 has a mounting hole with an internal thread on the inner wall of the mounting hole. The inner cavity of the mounting hole is threadedly inserted into the bottom of the bolt 913. When the two edge molds 1 are connected to the fixed shaft 910, the bolt 913 can rotate together with the fixed shaft 910. When the lower edge mold 1 is connected, the fixing block 2 912 is moved to the mounting hole position, and the tightening bolt 2 913 is rotated to make its bottom threadedly connected to the mounting hole, fixing the fixing seat 911 to the upper surface of one end of the lower edge mold 1. Then, the mounting tube 96 and the movable rod 97 are rotated to adjust the angle of the mounting tube 96 and the movable rod 97, and one end of the movable rod 97 slides in the inner cavity of the mounting tube 96 to adjust the position of the mounting seat 91 and the fixing block 1 92 at the top of the mounting tube 96, so that the fixing block 1 92 moves to the position of the corresponding threaded hole 94. The tightening bolt 1 93 is rotated, and one end of it is threadedly connected to the inner cavity of the threaded hole 94, fixing the mounting seat 91 and the fixing block 1 92 to one side edge mold 1, so that the mounting tube 96, the movable rod 97 and the two edge molds 1 form a triangular structure, which improves the connection strength between the edge molds 1. Furthermore, the positioning mechanism 10 includes multiple sleeves 101, positioning rods 102, limiting blocks 103, compression springs 104, positioning holes 105, mounting blocks 106, mounting shafts 107, movable blocks 108, protrusions 109, and bolts 1010. The top end of the sleeve 101 is fixedly connected to one side of the lower surface of the mounting base 91. The sleeve 101 moves together with the mounting base 91 to install the positioning rods 102. The top end of the positioning rod 102 slides through the inner cavity of the sleeve 101, which is used to position and fix multiple retaining molds 1. The top end of the positioning rod 102 slides in the inner cavity of the sleeve 101 to adjust the position of the positioning rod 102. The lower surface of the limiting block 103 is fixedly connected to the top end of the positioning rod 102, and it slides through the inner cavity of the sleeve 101. The limiting block 103 moves with the positioning rod 102 in the sleeve... The spring 104 is pressed against the inner cavity of sleeve 101, and the positioning rod 102 is prevented from disengaging from sleeve 101. The spring 104 is located in the inner cavity of sleeve 101 and is used to press the positioning rod 102 downward. When the positioning rod 102 slides upward, it drives the limiting block 103 to compress and deform the spring 104. The elasticity of the spring 104 is used to push the positioning rod 102 downward, ensuring that the bottom of the positioning rod 102 is stably inserted into the inner cavity of the positioning hole 105. Multiple positioning holes 105 are located at the top of one end of one of the side-mounted molds 1. The inner cavity of the positioning hole 105 is slidably inserted into the bottom of the positioning rod 102. The positioning hole 105 is used to install the positioning rod 102. By moving the mounting base 91, the bottom of the positioning rod 102 is slidably inserted into the inner cavity of the positioning hole 105, and the side-mounted mold 1 and the lower side-mounted mold 1 are positioned and installed. One side of the mounting block 106 is fixedly connected to the inner wall of the retaining mold 1. The two mounting blocks 106 correspond to the positions of the movable rod 97. One end of the mounting shaft 107 is fixedly connected to the outer wall of one of the mounting blocks 106. The mounting shaft 107 is used to mount the movable block 108. One end of the movable block 108 is rotatably inserted into one end of the mounting shaft 107, which is used to limit and fix the movable rod 97. The movable block 108 is elongated and rotates around the mounting shaft 107. By rotating the mounting tube 96 and the movable rod 97 upward around the fixed shaft 95, one end of the movable rod 97 rotates into the inner cavity of the two mounting blocks 106, and then rotates around the fixed shaft 95. The mounting shaft 107 rotates the movable block 108 so that one end of it is positioned on one side of the movable rod 97, limiting and fixing the movable rod 97. The movable rod 97 and the mounting tube 96 are stably housed in the inner cavity of the side-mounted mold 1. One end of the protrusion 109 is fixedly connected to the outer wall of the mounting shaft 107, which is used to limit one end of the movable block 108. The protrusion 109 is used to install bolt 3 1010. Bolt 3 1010 is threadedly connected to the other end of the protrusion 109. One end of bolt 3 1010 is pressed and fixed to one end of the movable block 108. By rotating and tightening bolt 3 1010, one end of bolt 3 1010 is pressed and fixed to the movable block 108, ensuring the stability of the movable block 108.

Otherwise, use a trowel to smooth the concrete and bury it. At the same time, the curing time is 8-16 hours. The concrete strength after leaving the kiln should not be less than 15 MPa. Step 8: Lay a single layer of wire mesh (7) with a hole diameter of 2.5 mm on both sides of the inner wall surface, and fix the wire mesh (7) with expansion bolts to ensure its stability. Pay attention to the tightness of the wire mesh (7) when fixing. Step 9: Lay radiation-proof mortar on both sides of the interior wall and smooth the surface to ensure a flat interior wall surface; Step 10: Check the surface and dimensions of the interior walls. Once you are sure they are correct, lift and remove all the formwork and clean the interior wall surface.
