Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a wall protection device for building renovation. Background Technology

[0002] During building construction, such as the renovation of the exterior wall, it is necessary to remove the original exterior wall plaster and install basalt fiber composite panels with thermal insulation properties. During the installation of basalt fiber composite panels, it takes a certain amount of time for the basalt fiber composite panels to form a bond with the wall.

[0003] The applicant discovered through a search that a Chinese patent discloses "a wall protection device for building renovation," with publication (announcement) number "CN 216866061." The patent, "U", primarily utilizes a wall panel support assembly. This assembly comprises several wall panel support components spaced vertically, each including a horizontal beam. Several sleeve plates spaced horizontally are mounted on the horizontal beam, with support plates slidably connected to the sleeve plates. The outer ends of the support plates are vertically positioned upwards, and the support plates are fixed to the sleeve plates by positioning screws. The front and rear ends of the horizontal beam are connected by long screws. The wall protection device for building renovation also includes wall panel edge support components fixedly mounted on the top of the long screws. This device design not only efficiently squeezes and positions loosely bonded wall panels during exterior wall renovation but also boasts high squeezing and positioning efficiency and facilitates easy removal after the wall panel is stabilized. However, the device can only be fixed within a predetermined extension distance and cannot adaptively extend or retract, significantly reducing its practicality. Furthermore, the device's fixing method is too simplistic, leading to significant safety hazards during use. Therefore, we propose a wall protection device for building renovation.

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0025] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Please see the appendix Figure 1 -Appendix Figure 6This utility model discloses a wall protection device for building renovation, comprising a main wall 1 and a support rod 2. A basalt fiber composite board 11 is adhered to the surface of the main wall 1. An extrusion assembly 3 is fitted to one side of the basalt fiber composite board 11. A fixing assembly 4 is provided at the bottom of the support rod 2. The extrusion assembly 3 consists of a housing 31, a spring 32, a telescopic rod 33, a push rod 34, and a friction ball 35. A cavity 3101 is provided inside the housing 31 to properly accommodate the spring 32, the telescopic rod 33, and the tail ends of the push rod 34. The bottom of the telescopic rod 33 is firmly fixed to the bottom of the cavity 3101, forming a stable support base and ensuring the stable operation of the extrusion assembly 3. The spring 32 tightly surrounds the outside of the telescopic rod 33, and, due to its elasticity, can adjust the pressure according to the actual thickness of the basalt fiber composite board 11. The push rod 34 is provided with an adaptive extension and retraction elastic force. Its rear end is securely connected to the front end of the telescopic rod 33. Under the synergistic action of the spring 32 and the telescopic rod 33, it can move flexibly back and forth. Friction balls 35 are evenly distributed on the front surface of the push rod 34, designed to significantly increase the friction when in contact with the basalt fiber composite board 11, thereby firmly fixing the basalt fiber composite board 11. Sliding grooves 3601 are precisely opened along the length direction on both sides of the outer shell 31. Correspondingly, matching sliding blocks 36 are installed on both sides of the rear end of the push rod 34. The sliding blocks 36 can slide smoothly within the sliding grooves 3601. This ingenious design effectively ensures that the push rod 34 remains stable during extension and retraction, avoiding wobbling and deviation, and ensuring the smooth operation of the push rod 34 against the basalt fiber composite board 11. The extrusion force of the basalt fiber composite board 11 always follows the correct direction. The outer shell 31 is installed on one side of the crossbar 5. Sliders 51 are provided at both ends of the crossbar 5. The support rod 2 is provided with a sliding rail 52 at the corresponding position. The crossbar 5 can move flexibly on the sliding rail 52 with the help of the sliders 51, so as to flexibly adjust the position of the extrusion component 3 according to the different positions of the basalt fiber composite board 11. The sliding rail 52 has evenly spaced limiting holes 6. Limiters 61 are installed in the limiting holes 6. The top of the limiter 61 is connected to the slider 51. When the slider 51 moves the crossbar 5 and the extrusion component 3 to the appropriate position, the limiter 61 cooperates with the limiting hole 6 to lock it, ensuring the stability of the device during use. The fixing component 4 includes a counterweight 41 and a positioning block 42. The device comprises a fixed rod 43, a base 44, and a triangular retainer 45. The support rod 2 is securely installed inside the triangular retainer 45 with screws 21. The triangular retainer 45 is firmly connected to the center of the base 44, providing stable support for the support rod 2. The fixed rod 43 is tightly fixed to one side of the base 44 via a threaded connection, further enhancing the connection stability between the device and the ground. Positioning blocks 42 are fixedly installed around the bottom of the counterweight 41. At the same time, positioning holes 4201 are precisely drilled at the corresponding positions of the top of the counterweight 41 and the top of the base 44. Through the cooperation of the positioning blocks 42 and the positioning holes 4201, the counterweight 41 and the base 44 can be quickly positioned and installed. In addition, fixing nails 7 are installed on both sides of the bottom of the base 44. During device installation, the fixing nails 7 are driven into the ground.This further strengthens the stability of the entire device on the ground, effectively reducing safety hazards caused by unstable support.

[0027] In the first embodiment, the outer shell 31 is provided with sliding grooves 3601 on both sides, and sliding blocks 36 are installed on both sides of the tail end of the push rod 34. The sliding blocks 36 are located inside the sliding grooves 3601. The fixing component 4 includes a counterweight 41, a positioning block 42, a fixing rod 43, a base 44, and a triangular fixing device 45. The support rod 2 is fixed inside the triangular fixing device 45 by screws 21. The triangular fixing device 45 is fixedly connected to the middle position of the base 44. The fixing rod 43 is fixedly connected to one side of the base 44 by threads. The positioning block 42 is fixedly installed around the bottom surface of the counterweight 41. Positioning holes 4201 are opened on the upper surface of the counterweight 41 and the upper surface of the base 44 at the corresponding positions of the positioning block 42.

[0028] Specifically, the sliding grooves 3601 formed on both sides of the outer casing 31 extend precisely and smoothly along the length of the outer casing 31, providing a reliable path for the smooth sliding of the sliding block 36. The sliding blocks 36 installed on both sides of the rear end of the push rod 34 are adapted in size and shape to the sliding grooves 3601. During the extension and retraction of the push rod 34, the sliding blocks 36, through close contact and good sliding cooperation with the sliding grooves 3601, strictly limit the movement trajectory of the push rod 34, ensuring that it can only move in a straight line along the predetermined direction of the sliding grooves 3601, thereby effectively preventing the push rod 34 from moving during operation. During the process, any shaking, offset, or torsion occurs, ensuring that the push rod 34 can always apply uniform and correct compressive force to the basalt fiber composite board 11 in a stable manner. This greatly improves the stability and reliability of the compressive assembly 3 in fixing the basalt fiber composite board 11. At the same time, positioning blocks 42 are fixedly installed around the bottom of the counterweight 41 by a solid welding or high-strength bolt connection. The distribution of these positioning blocks 42 is carefully designed to ensure the positioning accuracy and stability between the counterweight 41 and the base 44. The top of the counterweight 41 and the top of the base 44 are also fixedly installed. The positioning hole 4201, precisely drilled at the corresponding position, has a diameter matching the outer diameter of the positioning block 42, ensuring that the positioning block 42 can be tightly and accurately embedded in the positioning hole 4201. When it is necessary to install or remove the counterweight 41, the cooperation between the positioning block 42 and the positioning hole 4201 can quickly guide the counterweight 41 to the correct position, achieving rapid positioning and installation, greatly improving the convenience of device assembly and disassembly. Simultaneously, the fixing rod 43, through a fine threading process, achieves a tight threaded connection with the threaded hole on one side of the base 44. During installation, by rotating... Rotate the fixing rod 43 so that it is gradually screwed into the threaded hole of the base 44 until the specified torque value is reached, thereby firmly fixing the fixing rod 43 to the base 44. This connection method between the fixing rod 43 and the base 44 provides an additional support point for the fixation of the entire device on the ground. Combined with the stable support of the support rod 2 by the triangular fixing device 45 and the increased stability by the counterweight 41, the fixation effect of the entire device on the ground is significantly enhanced, effectively reducing the safety hazards that may be caused by unstable support, and ensuring the reliable operation of the wall protection device during building renovation work.

[0029] In embodiment 2, the outer shell 31 is installed on one side of the crossbar 5, and the crossbar 5 is provided with sliders 51 on both sides. The support rod 2 is provided with a sliding track 52 at the position corresponding to the slider 51. The sliding track 52 is provided with limiting holes 6 evenly inside. Limiters 61 are installed inside the limiting holes 6. The slider 51 is fixedly connected above the limiters 61. Fixing nails 7 are installed on both sides of the bottom of the base 44.

[0030] Specifically, the outer shell 31 is securely connected to the crossbar 5, and both ends of the crossbar 5 are equipped with sliders 51. The three work together to flexibly adjust the horizontal position of the extrusion assembly 3 according to the position of the basalt fiber composite board 11, improving the adaptability and ease of operation of the device. High-precision limiting holes 6 are evenly distributed in the sliding track 52, which fit tightly with the limiter 61. The fixing nails 7 on both sides of the bottom of the base 44 can be driven vertically into the ground with tools to anchor it tightly to the ground, enhancing the friction and adhesion between the base 44 and the ground. Combined with the functions of the counterweight 41, the triangular fixing device 45 and the fixing rod 43, the device's fixation effect on the ground is improved in all aspects, reducing safety risks.

[0031] Working principle:

[0032] First, place the fixing component 4 in a suitable ground position. Using the cooperation of the positioning block 42 and the positioning hole 4201, quickly install the counterweight 41 onto the base 44. Then, connect the fixing rod 43 to one side of the base 44 via threads, and simultaneously drive the fixing nail 7 into the ground to enhance the overall stability of the device. Next, fix the support rod 2 inside the triangular retainer 45 using screws 21. The triangular retainer 45 is fixed in the middle of the base 44, providing stable support for the support rod 2. Then, according to the position of the basalt fiber composite board 11, use the sliders 51 on both sides of the crossbar 5 to move it on the sliding track 52 of the support rod 2 to adjust the position. When the horizontal position of the pressing component 3 is reached, the crossbar 5 is locked by the limiter 61 cooperating with the limit hole 6. Then, the outer shell 31 of the pressing component 3 is brought close to the basalt fiber composite board 11. Due to the different thicknesses of the basalt fiber composite board 11, the push rod 34 is pushed, causing the sliding block 36 at the tail end of the push rod 34 to slide in the sliding grooves 3601 on both sides of the outer shell 31. At the same time, the spring 32 is compressed, and the telescopic rod 33 also extends and retracts accordingly. The friction ball 35 at the front end of the push rod 34 is in close contact with the basalt fiber composite board 11, increasing the friction force, thereby adaptively fixing the basalt fiber composite board 11 of different specifications. At this point, the entire process is completed.
