Description

Technical Field

[0001] This application relates to the field of renovation of old residential buildings, and in particular to an alarm device for the renovation of the exterior facade of old residential buildings and its usage method. Background Technology

[0002] The renovation of old buildings is currently an important part of urban planning and construction.

[0003] Over time, the facades of existing older residential buildings have become dirty, peeling, and cracked, affecting the city's aesthetics. Furthermore, the loose structural elements on the facades pose safety hazards to pedestrians. Therefore, in the process of urban modernization, the renovation of old building facades and the establishment of alarm systems for addressing structural loosening are crucial projects. Summary of the Invention

[0004] This application provides an alarm device and its usage method for the renovation of building facades in old residential areas, in order to enable real-time monitoring and alarm of building facade structures and improve the overall aesthetics of the city.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0006] An alarm device for the renovation of the exterior facade of an old residential building includes a leveling layer, an insulation layer, a crack-resistant layer, and a paint layer arranged sequentially from the direction closest to to the exterior facade. Multiple reinforcing bolts are installed on the side of the leveling layer away from the exterior facade, perpendicular to the leveling layer and extending away from the exterior facade. Through holes are provided in both the insulation layer and the crack-resistant layer for the reinforcing bolts to pass through. The end face of the reinforcing bolt away from the leveling layer is flush with the side face of the crack-resistant layer away from the insulation layer. A detection alarm system is installed on the reinforcing bolt to detect the position of the insulation layer and the crack-resistant layer.

[0007] By adopting the above-mentioned solution, when renovating the exterior facades of old residential buildings, reinforcement bolts can be installed on the side of the leveling layer away from the building facade. These bolts provide support for the leveling layer, insulation layer, and crack-resistant layer on the building facade, reducing the likelihood of detachment. Furthermore, the bolts serve as the mounting base for a detection and alarm system. Once installed, the system can detect the location of the insulation and crack-resistant layers. If these layers become loose on the building facade, potentially leading to detachment, the system will trigger an alarm. This allows for prompt repairs to be made to the insulation or crack-resistant layers on the building facade. This not only improves the overall aesthetics of the city but also reduces the possibility of falling objects injuring pedestrians.

[0008] Preferably, the detection alarm system includes a detection element installed on the reinforcing bolt for detecting the movement of the insulation layer and the crack-resistant layer, a control element coupled to the detection element, and an alarm element coupled to the control element.

[0009] Preferably, the thermal insulation layer includes a thermal insulation sheet layer and a thermal insulation mortar layer, the crack-resistant layer includes two crack-resistant mortar layers and a crack-resistant mesh layer disposed between the two crack-resistant mortar layers, and the detection component includes four mounting rings sleeved on the reinforcing bolt and threadedly connected to the reinforcing bolt. The four mounting rings correspond one-to-one with the thermal insulation sheet layer, the thermal insulation mortar layer and the two crack-resistant mortar layers. A transmission rod is provided between the mounting ring and the corresponding building facade layer, and a transmission component is provided on the mounting ring to detect the position of the transmission rod.

[0010] Preferably, the transmission component includes pressure sensors disposed on both sides of the transmission rod near and away from the building facade. The pressure sensors and the end of the transmission rod near the mounting ring are both located inside the circumferential surface of the mounting ring. A compressed spring is disposed between the transmission rod and the pressure sensor. The pressure sensor is coupled to the control component.

[0011] Preferably, multiple sets of alarm devices are set up, and the number of alarm devices is the same as the number of households in each building in the old community, and the two correspond one-to-one.

[0012] Preferably, there is a gap between two adjacent mounting rings, and multiple reinforcing holes are provided on the circumferential surface of the reinforcing bolt. The reinforcing holes are provided in the gap between the two mounting rings, and an injection hole is provided at the center of the reinforcing bolt. The injection hole and the reinforcing hole are connected.

[0013] Preferably, a locking ring is fitted on the reinforcing bolt, the locking ring is threaded to the reinforcing bolt, the reinforcing bolt is made of hard plastic, and the locking ring is provided with a cutting blade for cutting the reinforcing bolt.

[0014] Preferably, the cutting blade includes a cutting edge disposed on the locking ring and capable of reciprocating along the radial direction of the locking ring. The cutting edge is located on one side of the reinforcing bolt and the width of the cutting edge is the same as the outer diameter of the reinforcing bolt. A tightening groove is provided on the side of the reinforcing bolt away from the cutting edge and at a position opposite to the cutting edge, which is used in conjunction with the cutting edge.

[0015] Preferably, the locking ring is provided with a safety pin to fix the position of the cutting blade.

[0016] A method for using an alarm device for the renovation of the exterior facade of an old residential building includes the following steps:

[0017] S1. Cleaning: Clean the exterior facades of old residential buildings, removing dirt and other debris from the building facades.

[0018] S2. Leveling: Apply a concrete leveling layer to the exterior of the building and fix the bolt heads of the reinforcing bolts inside the leveling layer away from the exterior of the building.

[0019] S3. Thermal Insulation: Install thermal insulation sheets and thermal insulation mortar layers on the leveling layer. While installing the thermal insulation sheets, make an insertion hole near the reinforcing bolt for the drive rod to enter. That is, when the thermal insulation sheets are installed, the drive rod on the mounting ring corresponding to the thermal insulation sheets is inserted into the insertion hole; when applying the thermal insulation mortar layer, the drive rod on the mounting ring corresponding to the thermal insulation mortar layer is fixed inside the thermal insulation mortar layer.

[0020] S4. Crack resistance: On the side of the thermal insulation mortar layer away from the thermal insulation sheet, the crack resistance mortar layer, crack resistance mesh layer and crack resistance mortar layer are constructed in sequence. At this time, the transmission rod on the mounting ring corresponding to the crack resistance mortar layer is fixed inside the crack resistance mortar layer.

[0021] S5. Cutting and locking: Install the locking ring on the reinforcing bolt. At the same time, according to the thickness of the insulation layer and crack-resistant layer on the building facade, use a cutting knife to cut off the excess reinforcing bolt so that the reinforcing bolt is flush with the side of the crack-resistant layer away from the insulation layer.

[0022] S6. Adhesive injection: Add adhesive into the reinforcing bolt at the injection hole;

[0023] S7. Completion: After the adhesive has cooled, apply the paint finish to the excavated wall surface.

[0024] In summary, this application has the following technical effects:

[0025] 1. By installing the renovation alarm device, not only can the exterior facade of old residential buildings be renovated, but when the structure on the exterior facade is about to fall off, the renovation alarm device will trigger an alarm. After receiving the alarm, people can promptly repair the structure that is about to fall off. This achieves the goal of further reducing the possibility of people being injured by falling objects from high altitudes while ensuring the aesthetics of the city.

[0026] 2. By setting up multiple alarm devices, when the alarm devices are activated, people can quickly determine the area of ​​the structure that is about to fall off by the location of the alarm device, which can shorten the repair cycle of the structure that is about to fall off.

[0027] 3. By setting reinforcement holes and injection holes, after the crack-resistant layer is completed, adhesive can be added at the injection hole. After the adhesive passes through the reinforcement hole, it will bond with the structure around the reinforcement bolt, which can further improve the structural installation stability on the building facade.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] Reference Figure 1 This application provides an alarm device for the renovation of the exterior facade of an old residential building, including a leveling layer 2, an insulation layer 3, a crack-resistant layer 4, a waterproof layer 5, and a paint layer 6 arranged sequentially from the direction closest to to the exterior facade 1. Multiple reinforcing bolts 7 are provided on the side of the leveling layer 2 away from the exterior facade 1. In this embodiment, the reinforcing bolts 7 are made of rigid plastic and are perpendicular to the leveling layer 2. The reinforcing bolts 7 extend in the direction away from the exterior facade 1. Through holes are provided on both the insulation layer 3 and the crack-resistant layer 4 for the reinforcing bolts 7 to pass through. The end face of the reinforcing bolt 7 away from the leveling layer 2 is flush with the side face of the crack-resistant layer 4 away from the insulation layer 3. A detection alarm system 8 is provided on the reinforcing bolt 7 to detect the position of the insulation layer 3 and the crack-resistant layer 4.

[0035] When renovating the building facade 1, the original structure of the facade 1 must first be cleaned, and the facade 1 should be washed with high-pressure water to wet it. Then, a leveling layer 2 is applied to the facade 1. The leveling layer 2 will keep the facade 1 flush and facilitate subsequent construction. It is important to note that, depending on the size of the facade 1, multiple reinforcing bolts 7 need to be installed and fixed on the leveling layer 2. The bolt heads of the reinforcing bolts 7 must be fully inserted into the leveling layer 2. 2. Keep it vertical; then, on the leveling layer 2, construct the insulation layer 3, crack-resistant layer 4, waterproof layer 5, and paint layer 6 in sequence. The insulation layer 3 can improve the insulation capacity of the old community, and the crack-resistant layer 4 can reduce the possibility of cracking in the old community's houses under excessively high or low temperatures. The waterproof layer 5 is used to reduce the entry of external rainwater into the crack-resistant layer 4 and the insulation layer 3, reducing the possibility of rainwater entering and causing corrosion of the insulation layer 3. The paint layer 6 is the outermost structure of the building facade 1. People can apply some specific colors or patterns to the paint layer 6 to improve the aesthetics of the old community's houses.

[0036] It should be noted that during the construction of insulation layer 3 and crack-resistant layer 4, the detection alarm system 8 needs to be associated with the structures of insulation layer 3 and crack-resistant layer 4. The detection alarm system 8 can detect the position coefficients of insulation layer 3 and crack-resistant layer 4. When the position of insulation layer 3 or crack-resistant layer 4 is deviated, the detection alarm system 8 will issue an alarm command. After receiving the alarm signal, people can determine the specific location of insulation layer 3 and crack-resistant layer 4, and then repair insulation layer 3 or crack-resistant layer 4 according to the actual situation. This can reduce the possibility of people being injured by falling objects from high altitudes and extend the service life of the exterior wall structure of old residential areas.

[0037] In this embodiment, the thermal insulation layer 3 includes a thermal insulation sheet layer 31 and a thermal insulation mortar layer 32, and the crack-resistant layer 4 includes two crack-resistant mortar layers 41 and a crack-resistant mesh layer 42 disposed between the two crack-resistant mortar layers 41.

[0038] Reference Figure 1 and Figure 2The modified alarm device includes a detection component 81, a control component 82, and an alarm component 83. The detection component 81 includes a mounting ring 811, a transmission rod 812, and a transmission component 813. The mounting ring 811 is sleeved on the reinforcing bolt 7 and threadedly connected to the reinforcing bolt 7. The number of mounting rings 811 is related to the total number of insulation sheet layer 31, insulation mortar layer 32, and crack-resistant mortar layer 41. In this embodiment, there are four mounting rings 811. The four mounting rings 811 are connected to the insulation sheet layer 31. The thermal insulation mortar layer 32 and the two crack-resistant mortar layers 41 are one-to-one. Multiple transmission rods 812 are provided along the circumference of the mounting ring 811. The transmission rods 812 extend along the radial direction of the mounting ring 811. The end of the transmission rod 812 away from the mounting ring 811 is fixedly connected to one of the thermal insulation sheet layer 31, the thermal insulation mortar layer 32, and the two crack-resistant mortar layers 41. The transmission component 813 is set on the mounting ring 811 and can detect the position of the transmission rod 812.

[0039] Combined Figure 3 The transmission component 813 includes a pressure sensor 814 and a spring 815. The end of the transmission rod 812 near the mounting ring 811 extends into the mounting ring 811. The mounting ring 811 has a clearance groove for the transmission rod 812 to reciprocate along the axis of the mounting ring 811. Two pressure sensors 814 are provided, both of which are located inside the clearance groove and on both sides of the transmission rod 812. Two springs 815 are also provided, each located on both sides of the transmission rod 812 and both are in a compressed state.

[0040] Reference Figure 4 In this embodiment, the control unit 82 is a single-chip microcomputer, and there are multiple sets of alarm units 83. The number of alarm units 83 is the same as the number of households in the residential building, and each alarm unit 83 corresponds to a residential building. The alarm units 83 are a display 831 and an alarm bell 832 installed indoors. The display 831 can display the pressure value received by the pressure sensor 814 in real time, and the alarm bell 832 will perform an alarm action when the pressure received by the pressure sensor 814 is abnormal.

[0041] After the insulation layer 3 and crack-resistant layer 4 are completed, the transmission rod 812 is in a balanced state under the action of the springs 815 on both sides. At this time, the pressure on the pressure sensors 814 on both sides is approximately equal. The microcontroller has a preset pressure value. When the insulation layer 3 or crack-resistant layer 4 shifts or may fall off later, the pressure values ​​of the pressure sensors 814 on both sides of the transmission rod 812 will change. If the change in pressure value exceeds the preset value in the microcontroller, the alarm bell 832 will start to sound an alarm, and people can then inspect and repair the insulation layer 3 or crack-resistant layer 4. Setting multiple alarm components 83 is mainly to facilitate people to quickly determine the area where the insulation layer 3 or crack-resistant layer 4 is about to fall off, shortening the inspection and repair cycle.

[0042] Reference Figure 1 and Figure 2 In this embodiment, the detection alarm system 8 also enhances the stability of the building facade 1, specifically as follows: There is a gap between two adjacent mounting rings 811 on the reinforcing bolt 7. Multiple reinforcing holes 71 are formed on the circumference of the reinforcing bolt 7, located within the gap between the two mounting rings 811. An injection hole 72 is formed at the center of the reinforcing bolt 7, and the injection hole 72 is connected to the reinforcing hole 71. After the crack-resistant layer 4 is constructed, adhesive can be added into the reinforcing bolt 7 at the injection hole 72. The adhesive will penetrate the reinforcing hole 71 and bond to the surrounding insulation layer 3 or crack-resistant layer 4, thus further enhancing the structural stability of the building facade 1.

[0043] The thickness of the structural components on the building facade 1 varies depending on factors such as the construction area. To facilitate the use of the reinforcing bolt 7, a locking ring 73 is fitted onto the reinforcing bolt 7. The locking ring 73 is threadedly connected to the reinforcing bolt 7, and a cutting blade 74 is provided on the locking ring 73 for cutting the reinforcing bolt 7. After the locking ring 73 is installed on the reinforcing bolt 7, it presses the crack-resistant layer 4 tightly onto the insulation layer 3. To keep the side of the crack-resistant layer 4 away from the insulation layer 3 flush, a clearance groove is provided on the crack-resistant layer 4 for the locking ring 73 to enter. The locking ring 73 makes the structure on the building facade 1 more stable. When the length of the reinforcing bolt 7 is greater than the thickness of the structure on the building facade 1, the excess part of the reinforcing bolt 7 can be cut off using the cutting blade 74, making the reinforcing bolt 7 easier to use.

[0044] In this embodiment, the cutting blade 74 includes a cutting edge 741, a clamping groove 742, and a safety pin 743. The cutting edge 741 is disposed on one side of the locking ring 73. The cutting edge 741 is slidably connected to the locking ring 73, allowing the cutting edge 741 to reciprocate along the radial direction of the locking ring 73. The cutting edge 741 is located on one side of the reinforcing bolt 7, and the width of the cutting edge 741 is the same as the outer diameter of the reinforcing bolt 7. The portion of the cutting edge 741 near the reinforcing bolt 7 is semi-circular. The clamping groove 742 is disposed on the side of the locking ring 73 opposite to the cutting edge 741 and can clamp the reinforcing bolt 7. The sides of the cutting edge 741 and the clamping groove 742 that are close to each other can cooperate with each other. The safety pin 743 is disposed on the locking ring 73 and can fix the position of the cutting edge 741.

[0045] The safety pin 743 on the locking ring 73 can fix the position of the cutting blade 741. The safety pin 743 can prevent the cutting blade 741 from moving and scratching people. When the reinforcing bolt 7 needs to be cut with the cutting knife 74, remove the safety pin 743 from the locking ring 73, and then move the cutting knife 74 towards the top tightening groove 742. The cutting knife 74 will cut the reinforcing bolt 7, making the reinforcing bolt 7 easier to use.

[0046] This application also provides a method for using an alarm device for the renovation of the exterior facade of old residential buildings, including the following steps:

[0047] S1. Cleaning: Clean the exterior facade 1 of the old residential building, removing dirt and other debris from the surface of the exterior facade 1.

[0048] S2. Leveling: Apply concrete to the exterior facade 1 to form a leveling layer 2, and at the same time fix the bolt heads of the reinforcing bolts 7 to the inside of the leveling layer 2 away from the exterior facade 1.

[0049] S3. Thermal Insulation: Install thermal insulation sheet 31 and thermal insulation mortar layer 32 on the leveling layer 2. While installing thermal insulation sheet 31, make an insertion hole for transmission rod 812 to enter at the position of thermal insulation sheet 31 near the reinforcing bolt 7. That is, when thermal insulation sheet 31 is installed, transmission rod 812 on the mounting ring 811 corresponding to thermal insulation sheet 31 is inserted into the insertion hole; when applying thermal insulation mortar layer 32, transmission rod 812 on the mounting ring 811 corresponding to thermal insulation mortar layer 32 is fixed inside thermal insulation mortar layer 32.

[0050] S4. Crack resistance: On the side of the thermal insulation mortar layer 32 away from the thermal insulation sheet layer 31, the crack-resistant mortar layer 41, the crack-resistant mesh layer 42 and the crack-resistant mortar layer 41 are constructed in sequence. At this time, the transmission rod 812 on the mounting ring 811 corresponding to the crack-resistant mortar layer 41 is fixed inside the crack-resistant mortar layer 41.

[0051] S5. Cutting and locking: Install the locking ring 73 on the reinforcing bolt 7. At the same time, according to the thickness of the insulation layer 3 and the crack-resistant layer 4 on the building facade 1, use the cutting knife 74 to cut off the excess reinforcing bolt 7 so that the reinforcing bolt 7 is flush with the side of the crack-resistant layer 4 away from the insulation layer 3.

[0052] S6. Adhesive injection: Add adhesive to the reinforcing bolt 7 at the injection hole 72;

[0053] S7. Completion: After the adhesive has cooled, apply the paint layer 6 to the excavated wall surface.

[0054] This specific embodiment is merely an explanation of this application and is not intended to limit it.
