[0002] House renovation is to improve the functionality and safety of the house, especially in many old urban areas or rural areas where there are many old houses, such as bungalow residential buildings, office buildings, etc. Due to their long construction years, these old houses usually have many common problems, such as leakage, serious material aging, poor thermal insulation and other problems. Therefore, these old houses need to be renovated to improve their living performance.

[0003] The main purpose of the thermal insulation structure is to reduce the transfer and loss of energy to maintain the stability of the indoor temperature; the main purpose of the waterproof structure is to prevent moisture from penetrating into the building and protect the building structure and interior decoration from damage; the main purpose of the fireproof structure is to have a certain fire resistance time when a fire occurs inside the building, so as to reduce the damage to the building and casualties.

[0004] A Chinese patent with announcement number CN108678409A provides a method for renovating an old house and a renovation structure thereof. The steps of the old house renovation method are as follows: the roof of the old house is demolished, and at least the old house walls are retained; support columns are installed on the outside of the house walls according to the layout of the house walls; a roof bracket is installed, and the roof bracket is installed on the support column, wherein the support column completely bears the weight of the roof bracket; resin tiles are laid, and the resin tiles are laid on the roof bracket to form a roof.

[0005] Although the above-mentioned technology can solve the problems caused by the deterioration of the wall structure of the house during the construction process, the renovation process mainly tends to strengthen the structural strength of the house, and does not improve the insulation, waterproofing and fire prevention of the renovated house, which has some shortcomings. Summary of the invention

[0006] In order to improve the problems of insufficient insulation, waterproofing and fire prevention in renovated houses, the present application provides a waterproof, fireproof and heat-insulating structure for house renovation.

[0007] The present application provides a waterproof, fireproof and heat-insulating structure for house reconstruction using the following technical solutions: A waterproof, fireproof and heat-insulating structure for house reconstruction comprises a waterproof board, a flame retardant board, a heat-insulating board and a fixing assembly, wherein a plurality of the heat-insulating boards are arranged on the side walls and the top of the house, the walls around the house or the top ceiling are located between the flame retardant board and the waterproof board, the heat-insulating board is located on the side of the flame retardant board facing away from the waterproof board, and the fixing assembly is used to fix the heat-insulating board, the flame retardant board and the waterproof board on the wall of the house.

[0008] By adopting the above technical scheme, the renovation personnel install and fix the waterproof board, flame retardant board and thermal insulation board on the house through fixing components. The waterproof board made of hydrophobic material prevents external rainwater from flowing onto the house body. The thermal insulation board made of thermal insulation material is laid indoors to insulate the house body. The flame retardant board made of high temperature resistant material blocks the spread of fire in the house, thereby improving the waterproof, fireproof and thermal insulation effects of the renovated house.

[0009] Optionally, the fixing assembly includes a reinforcement plate arranged between the house and the waterproof board, the reinforcement plate is used to strengthen the strength of the house wall, the insulation board is detachably provided with a fixing rod, the fixing rod sequentially passes through the insulation board, the flame retardant board, the house wall and the reinforcement plate, the fixing rod is threaded with a fixing nut, the fixing nut is used to tighten the reinforcement plate, and a connecting piece for installation is provided between the reinforcement plate and the waterproof board.

[0010] By adopting the above technical solution, the renovation personnel place the insulation board and the flame retardant board on the wall, then pass the fixing rod through the insulation board and the flame retardant board, then put the reinforcement board on the fixing rod, and finally tighten the fixing nut to fix the reinforcement board to the outside of the house. Finally, fix the waterproof board to the reinforcement board through the connecting parts. The reinforcement board will strengthen the wall strength of the renovated house, which is beneficial to improve the service life of the wall.

[0011] Optionally, the connecting member includes a cross bar arranged on the reinforcement plate, and a plurality of the reinforcement plates are arranged on the same side of the house wall. The plurality of reinforcement plates on the same side of the house wall are arranged along the length direction of the cross bar, and a slot is provided on the cross bar. An elastic clip is provided on the waterproof plate, and the elastic clip is used to be stuck in the slot.

[0012] By adopting the above technical solution, the renovation personnel can quickly install the waterproof board on the cross bar on the reinforcement plate through the plug-in cooperation between the elastic clip strip and the slot. The waterproof board separates the outside of the wall from the outside world, thereby achieving a waterproof effect, which is beneficial to reduce the installation difficulty of the renovation personnel. Since the cross bar and the reinforcement plate are perpendicular to each other, it is beneficial to further improve the structural strength of the wall.

[0013] Optionally, the insulation plate includes a first unit plate and a second unit plate, and the first unit plate and the second unit plate are both provided with a fixing groove for the fixing rod to pass through, and the first unit plate and the second unit plate are rotatably matched, and the rotating contact end surfaces of the first unit plate and the second unit plate are both set to inclined surfaces, and the tip angle formed by the inclined surface and its adjacent side surface is 45°, and a shaft cylinder with a hollow interior and an open end is set on the inclined surface of the first unit plate, and a pull plate is coaxially slidably arranged in the shaft cylinder, and a fixed compression spring is supported between the pull plate and the closed end of the shaft cylinder, and a pull rod is coaxially arranged on the pull plate, and the pull rod slides through the closed end of the shaft cylinder and is detachably arranged on the second unit plate, and a locking member for fixing is set between the first unit plate and the second unit plate.

[0014] By adopting the above technical solution, when it is necessary to lay the insulation board at the angle between the roof and the wall of the house, the renovation personnel release the locking effect of the locking piece, and then pull the first unit plate to move the first unit plate and the second unit plate back to back. The second unit plate drives the pull plate through the pull rod to squeeze the fixed compression spring, and the fixed compression spring is deformed under pressure. Then the second unit plate is rotated to make the first unit plate perpendicular to the second unit plate, so as to adapt to the angle between the roof and the wall of the house, reduce the installation gap caused by installing the insulation board at the angle between the roof and the wall of the house, and help to improve the insulation effect of the house.

[0015] Optionally, the locking member includes a locking pin slidably set on the second unit plate, the second unit plate is provided with a pin groove for the locking pin to slide, the first unit plate is provided with a locking groove for the locking pin to be inserted, the pin groove is threadedly connected to an adjustment block at one end facing away from the first unit plate, and a locking compression spring is supported between the locking pin and the adjustment block.

[0016] By adopting the above technical solution, the reconstruction personnel loosen the adjusting block, and when the first unit plate and the second unit plate move back to back, the second unit plate drives the locking pin to disengage from the locking groove on the first unit plate, thereby facilitating the second unit plate to rotate around the shaft tube on the first unit plate. When the locking pin on the second unit plate is inserted into the locking groove on the first unit plate again, the reconstruction personnel tighten the adjusting block, the locking compression spring is deformed under pressure and presses the locking pin onto the locking groove on the first unit plate, which helps to reduce the possibility of accidental rotation of the first unit plate and the second unit plate.

[0017] Optionally, the waterproof board on the top of the house is surrounded by overflow gutter boards with a U-shaped cross-section, a sealing waterproof strip is arranged between the edge on one side of the overflow gutter board and the waterproof board on the top of the house, a wrapping board is arranged on the edge on the other side of the overflow gutter board, and the wrapping board is wrapped around the parapet on the top of the house, a drainage gutter board with a U-shaped cross-section is arranged on the house, the drainage gutter board is connected with a drainage pipe, and a through pipe is connected between the drainage gutter board and the overflow gutter board.

[0018] By adopting the above technical solution, the renovation personnel welded and installed the overflow gutter plate and the cladding plate on the top of the house. The rainwater falling on the waterproof plate on the top of the house will flow into the overflow gutter plate, and flow into the drainage gutter plate through the through pipe, and finally be discharged to the outside through the drainage pipe, thereby reducing the possibility of direct contact between the house wall and rainwater.

[0019] Optionally, a sealing strip is provided between two adjacent insulation boards, and a seal groove for placing the sealing strip is opened on the insulation board.

[0020] By adopting the above technical solution, the possibility of outdoor moisture entering indoors is further reduced.

[0021] Optionally, an elastic bag is provided in the fixed groove on the side facing the flame retardant plate, and solid sodium bicarbonate is filled in the elastic bag. An air hole with an L-shaped cross-section is provided on the fixed rod, one end of the air hole extends to the outside of the reinforcement plate, and the other end is connected to the elastic bag. A whistle is provided on the air hole of the fixed rod.

[0022] By adopting the above technical solution, when a fire occurs indoors, the indoor temperature rises and the temperature is transmitted to the fixed rod. The temperature rise on the fixed rod causes the solid sodium bicarbonate to decompose by heat to produce a large amount of gas. The large amount of gas produced flows through the air holes to the whistle, causing the whistle to make a sound, thereby promptly reminding people of possible fires, which is beneficial to improving the safety of the residents.

[0023] Optionally, a waterproof membrane is adhered to the end of the air hole where the fixing rod extends outside the reinforcement plate, and the waterproof membrane is easily damaged by expansion.

[0024] By adopting the above technical scheme, the waterproof membrane prevents external moisture from entering the elastic bag through the pores, so that the solid sodium bicarbonate in the elastic bag is decomposed by moisture. When the indoor temperature continues to rise, the gas generated by the heat expands rapidly in the pores, and the pressure in the pores increases until the waterproof membrane is damaged by the expansion. The air pressure in the pores is quickly released, and the air flow passes through the whistle to make a loud sound, which is conducive to improving the timeliness of people's response to indoor fires.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The renovation personnel install and fix the waterproof board, flame retardant board and insulation board on the house through fixing components. The waterproof board made of hydrophobic material prevents rainwater from flowing onto the house. The insulation board made of insulation material is laid indoors to insulate the house. The flame retardant board made of high temperature resistant material blocks the spread of fire in the house, thereby improving the waterproof, fireproof and insulation effects of the renovated house. 2. The renovation personnel can quickly install the waterproof board on the crossbar on the reinforcement board by plugging and matching the elastic clip strip with the slot. The waterproof board separates the outside of the wall from the outside world, thereby achieving a waterproof effect, which is conducive to reducing the installation difficulty of the renovation personnel. Since the crossbar and the reinforcement board are perpendicular to each other, it is conducive to further improving the structural strength of the wall; 3. When it is necessary to lay the insulation board at the angle between the roof and the wall of the house, the renovation personnel release the locking effect of the locking piece, and then pull the first unit board to make the first unit board and the second unit board move back to back. The second unit board drives the pull plate to squeeze the fixed compression spring through the pull rod, and the fixed compression spring is deformed under pressure. Then the second unit board is rotated to make the first unit board and the second unit board perpendicular to each other, so as to adapt to the angle between the roof and the wall of the house, reduce the installation gap caused by installing the insulation board at the angle between the roof and the wall of the house, and help improve the insulation effect of the house; 4. The waterproof membrane prevents external moisture from entering the elastic bag through the pores, causing the solid sodium bicarbonate in the elastic bag to decompose due to moisture. When the indoor temperature continues to rise, the gas generated by the heat expands rapidly in the pores, and the pressure in the pores increases until the waterproof membrane is damaged by the expansion. The air pressure in the pores is quickly released, and the air flow passes through the whistle and makes a loud sound, which is conducive to improving the timeliness of people's response to indoor fires.

An elastic card strip 443 is welded on the waterproof plate 1. The elastic card strip 443 can be made of plastic material and is used to be stuck in the card slot 442.

[0039] The renovation personnel first open holes on the wall and top ceiling of house 0 for the fixing rod 42 to pass through, and then install and fix the flame retardant board 2 and the insulation board 3 inside house 0 through the fixing rod 42, and then put the reinforcement board 41 on the fixing rod 42 outside house 0, and fill the sealing glue around the fixing rod 42 between the reinforcement board 41 and house 0, and finally fix the flame retardant board 2 and the insulation board 3 to house 0 through the fixing nut 43.

[0040] A cross bar 441 is welded to the reinforcement plate 41 on the outer wall and outer top of the house 0 so that the cross bar 441 and the reinforcement plate 41 form a cross-net structure, and then the waterproof board 1 is fixed to the cross bar 441 by plugging and fitting the elastic clip 443 and the slot 442, and sealing glue is applied to the joint between two adjacent waterproof boards 1.

[0041] When it rains, rainwater falling on the waterproof board 1 on the top of the house 0 will flow into the overflow trough board 5, and flow into the drainage trough board 8 through the through pipe 10, and finally be discharged to the outside through the drainage pipe 9, thereby separating the wall from the outside rainwater.

[0042] Reference Figure 2 , Figure 3 and Figure 4 The insulation board 3 includes a first unit board 31 and a second unit board 32. The first unit board 31 and the second unit board 32 are both provided with a fixing slot 33 for the fixing rod 42 to pass through. The first unit board 31 and the second unit board 32 are rotatably matched. The rotational contact end surfaces of the first unit board 31 and the second unit board 32 are both arranged as inclined surfaces 34. The tip angle formed by the inclined surface 34 and its adjacent side surface is 45°.

[0043] Reference Figure 2 , Figure 3 and Figure 4 A shaft cylinder 35 which is hollow inside and opens at one end toward the first unit plate 31 is welded on the inclined surface 34 of the first unit plate 31, a pull plate 36 is coaxially slidably arranged inside the shaft cylinder 35, a fixed compression spring 37 is supported between the pull plate 36 and the closed end of the shaft cylinder 35, a pull rod 38 is coaxially welded on the pull plate 36, the pull rod 38 slides through the closed end of the shaft cylinder 35 and is bolted to the second unit plate 32, and a locking member 39 for fixing is arranged between the first unit plate 31 and the second unit plate 32.

[0044] Reference Figure 2 , Figure 3 and Figure 4 The locking member 39 includes a locking pin 391 slidably connected to the second unit plate 32, a pin groove 392 for the sliding movement of the locking pin 391 is provided on the second unit plate 32, a locking groove 393 for the insertion of the locking pin 391 is provided on the first unit plate 31, an adjustment block 394 is threadedly connected to the end of the pin groove 392 facing away from the first unit plate 31, and a locking compression spring 395 is supported between the locking pin 391 and the adjustment block 394.

[0045] When it is necessary to lay the insulation board 3 at the angle between the top of the house 0 and the wall, the renovation personnel loosen the adjustment block 394, and then pull the first unit plate 31 to make the first unit plate 31 and the second unit plate 32 move back to back, and the second unit plate 32 drives the pull plate 36 to squeeze the fixed compression spring 37 through the pull rod 38, and the fixed compression spring 37 is deformed under pressure. At this time, the second unit plate 32 drives the locking pin 391 to disengage from the locking groove 393 on the first unit plate 31, and then rotates the second unit plate 32 to make the first unit plate 31 and the second unit plate 32 perpendicular.

[0046] Then the second unit plate 32 is loosened, and the reaction force of the fixed compression spring 37 to restore the deformation makes the second unit plate 32 pressed against the first unit plate 31. Then the renovation personnel tighten the adjustment block 394, the locking compression spring 395 is compressed and deformed and presses the locking pin 391 against the locking groove 393 on the first unit plate 31 to adapt to the angle between the top of the house 0 and the wall.

[0047] Reference Figure 2 , Figure 3 and Figure 4 An elastic bag 13 is arranged on the side of the fixed groove 33 facing the flame retardant plate 2, and solid sodium bicarbonate 14 is filled in the elastic bag 13. An air hole 15 with an L-shaped cross-section is opened on the fixed rod 42. One end of the air hole 15 extends to the outside of the reinforcement plate 41, and the other end is connected to the elastic bag 13. A whistle 16 is bolted to the air hole 15 of the fixed rod 42, and a waterproof film 17 is pasted on the end of the air hole 15 extending from the fixed rod 42 to the outside of the reinforcement plate 41. The waterproof film 17 can be made of a plastic material that is easily damaged by expansion.

[0048] When a fire occurs indoors and the temperature inside the room rises, the thermal insulation board 3 made of aluminum silicate board and the flame retardant board 2 made of rock wool board prevent the temperature from diffusing to the wall, thereby causing the temperature inside the room to rise rapidly. The indoor temperature is transferred to the fixed rod 42, and the temperature on the fixed rod 42 causes the solid sodium bicarbonate 14 to decompose rapidly by heat and produce a large amount of gas through heat transfer.

[0049] Due to the obstruction of the waterproof membrane 17, a large amount of generated gas gathers in the pore 15, and the pressure in the pore 15 continues to rise until the waterproof membrane 17 is damaged due to expansion. The air pressure in the pore 15 is quickly released, and the high-speed airflow flows through the whistle 16 and emits a loud sound, thereby reminding people that there is a fire indoors.

[0050] The implementation principle of a waterproof, fireproof and heat-insulating structure for house renovation in an embodiment of the present application is as follows: the renovation personnel first open holes on the wall and top ceiling of house 0 for the fixing rod 42 to pass through, and then install and fix the flame retardant board 2 and the heat-insulating board 3 inside house 0 through the fixing rod 42, and then put the reinforcement plate 41 on the fixing rod 42 outside house 0, and at the same time fill sealant around the fixing rod 42 between the reinforcement plate 41 and house 0, and finally fix the flame retardant board 2 and the heat-insulating board 3 on house 0 through the fixing nut 43.

[0051] A cross bar 441 is welded to the reinforcement plate 41 on the outer wall and outer top of the house 0 so that the cross bar 441 and the reinforcement plate 41 form a cross-net structure, and then the waterproof board 1 is fixed to the cross bar 441 by plugging and fitting the elastic clip 443 and the slot 442, and sealing glue is applied to the joint between two adjacent waterproof boards 1.

[0052] When it rains, rainwater falling on the waterproof board 1 on the top of the house 0 will flow into the overflow trough board 5, and flow into the drainage trough board 8 through the through pipe 10, and finally be discharged to the outside through the drainage pipe 9, thereby separating the wall from the outside rainwater.

[0053] When it is necessary to lay the insulation board 3 at the angle between the top of the house 0 and the wall, the renovation personnel loosen the adjustment block 394, and then pull the first unit plate 31 to make the first unit plate 31 and the second unit plate 32 move back to back, and the second unit plate 32 drives the pull plate 36 to squeeze the fixed compression spring 37 through the pull rod 38, and the fixed compression spring 37 is deformed under pressure. At this time, the second unit plate 32 drives the locking pin 391 to disengage from the locking groove 393 on the first unit plate 31, and then rotates the second unit plate 32 to make the first unit plate 31 and the second unit plate 32 perpendicular.

[0054] Then the second unit plate 32 is loosened, and the reaction force of the fixed compression spring 37 to restore the deformation makes the second unit plate 32 pressed against the first unit plate 31. Then the renovation personnel tighten the adjustment block 394, the locking compression spring 395 is compressed and deformed and presses the locking pin 391 against the locking groove 393 on the first unit plate 31 to adapt to the angle between the top of the house 0 and the wall.

[0055] When a fire occurs indoors and the temperature inside the room rises, the thermal insulation board 3 made of aluminum silicate board and the flame retardant board 2 made of rock wool board prevent the temperature from diffusing to the wall, thereby causing the temperature inside the room to rise rapidly. The indoor temperature is transferred to the fixed rod 42, and the temperature on the fixed rod 42 causes the solid sodium bicarbonate 14 to decompose rapidly by heat and produce a large amount of gas through heat transfer.

[0056] Due to the obstruction of the waterproof membrane 17, a large amount of generated gas gathers in the pore 15, and the pressure in the pore 15 continues to rise until the waterproof membrane 17 is damaged due to expansion. The air pressure in the pore 15 is quickly released, and the high-speed airflow flows through the whistle 16 and emits a loud sound, thereby reminding people that there is a fire indoors.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
