Technical Field
[0001] This invention relates to the field of brick masonry reinforcement technology using UHP-ECC material containing PE fibers, specifically to a brick masonry structure reinforced with UHP-ECC material containing PE fibers and its preparation method. Background Technology
[0002] In the field of building construction, brick masonry structures have long been widely used in various buildings such as residences, factories, and ancient buildings due to their convenient material sourcing and low cost. However, with the increase in service life and the influence of factors such as load changes, environmental erosion, and natural disasters, a large number of brick masonry structures have gradually developed problems such as cracking, peeling, and reduced load-bearing capacity. This not only affects the appearance of the building but also seriously threatens the structural safety, and reinforcement and repair are urgently needed. Traditional methods of reinforcing brick masonry often employ techniques such as cement mortar finishing, steel mesh reinforcement, and ordinary concrete encasing. However, these techniques have significant limitations: Cement mortar plastering is prone to cracking due to shrinkage, has poor adhesion to the brick masonry base, and its reinforcement effect is short-term and easily fails. Steel mesh reinforcement requires on-site binding and welding, which is complicated in construction process. In addition, steel bars are prone to corrosion and have high maintenance costs in the later stage. Ordinary concrete itself is brittle and has poor crack resistance. It is difficult to adapt to the small deformation of the brick masonry structure during the stress process, and it is prone to secondary cracking, which cannot guarantee the long-term structural stability. To address the shortcomings of traditional reinforcement technologies, the engineering field has increasingly focused on the research and application of high-performance cement-based composite materials. UHP-ECC, as a new type of high-performance material, features high strength, high toughness, and excellent crack resistance, making it an ideal candidate material for brick masonry reinforcement. However, existing UHP-ECC materials still have shortcomings in preparation and application: on the one hand, the mixing uniformity of mineral admixtures and fine aggregates is poor during material preparation, which easily leads to local component deviations and affects the overall performance of the material; on the other hand, when adding fibers to improve toughness, the fibers are prone to agglomeration and uneven dispersion, resulting in fluctuations in the mechanical properties of the material. Moreover, existing preparation equipment is mostly a single mixing structure, which cannot achieve precise control of dry mixing and wet mixing in stages, resulting in low production efficiency. Therefore, it is necessary to design a UHP-ECC material containing PE fibers to reinforce brick masonry structures and its preparation method to solve the above problems. Summary of the Invention

[0012] Preferably, the feeding tube extends through the interior of the fixed platform, facilitating the feeding of the prepared UHP-ECC material through the feeding tube.
[0013] The preparation method of UHP-ECC material containing PE fiber to reinforce brick masonry includes the following steps: Dry Mix of S1 and UHP-ECC Materials First, the connecting arm and premix box are moved by the second hydraulic cylinder, so that the bottom of the premix box contacts the top of the mixing box. At this time, the proportioned cement, silica fume, fly ash, fine aggregate and other mineral admixtures and fine aggregates can be poured into the premix box. The first servo motor drives the first stirring shaft and the first scraper fixedly connected to the outside of the rotating rod to rotate. Under the action of the first stirring shaft and the first scraper, the aggregate in the premix box can be dry mixed. After the dry mixing is completed, the baffle is moved to the left by the first hydraulic cylinder. At this time, the bottom of the premix box can be opened, and the dry material after dry mixing can enter the mixing box. Because the rotating rod drives the first scraper to rotate and the bottom contacts the bottom of the premix box, the smooth discharge of the dry material can be guaranteed. S2, UHP-ECC material wet mixing When the dry material after dry mixing enters the mixing chamber, the rotating rod will synchronously drive the second stirring shaft and the second scraper to rotate. During the mixing process, the water-reducing agent is pre-dissolved in water and then slowly added to the dry material being mixed through the water injection pipe. The mixing continues. After a certain period of mixing, the proportioned PE fiber can be put into the hopper. The second servo motor drives the rotating shaft and the sealing plate to rotate. By adjusting the angle of the sealing plate inside the hopper, the speed and amount of PE fiber feeding can be controlled, so that the PE fiber enters the dry material being mixed in the mixing chamber in small amounts and multiple times, ensuring that the fiber is evenly dispersed and avoiding clumping. S3 and UHP-ECC material cutting Once the UHP-ECC material is prepared, the collection device can be placed at the bottom of the discharge pipe. The third hydraulic cylinder drives the fixed plate to move forward within the discharge pipe and fixed platform, thus discharging the UHP-ECC material. When the rotating rod rotates, it drives the second scraper to rotate, and the bottom of the second scraper contacts the bottom of the mixing box, ensuring smooth material discharge and avoiding material residue. After the material is discharged, the workers can evenly apply the UHP-ECC material to the cleaned masonry surface.
[0014] Compared with the prior art, the present invention provides a method for reinforcing brick masonry structures with UHP-ECC material containing PE fibers and the same, which has the following beneficial effects: The invention relates to a method for reinforcing brick masonry structures using UHP-ECC material containing PE fibers. The method involves a pre-mixing mechanism where, when reinforcing brick masonry requires the use of UHP-ECC material and the bottom of the premixing tank is positioned at the top of the mixing tank, the proportioned cement, silica fume, fly ash, fine aggregate, and other mineral admixtures and fine aggregates are first poured into the premixing tank. A first servo motor drives a first stirring shaft and a first scraper, which are fixedly connected to the rotating rod, to rotate. Under the action of the first stirring shaft and the first scraper, the aggregates in the premixing tank are stirred. In the dry mixing process, the mineral admixtures and fine aggregates continuously change positions under the stirring action of the first stirring shaft, achieving full contact and mixing between the materials. This provides a uniform base material for subsequent wet mixing, ensuring the stability of the UHP-ECC material performance. After the dry mixing is completed, the first hydraulic cylinder can drive the baffle to move to the left. At this time, the bottom of the premixing box can be opened, and the dry material after dry mixing can enter the mixing box. Because the rotating rod drives the first scraper to rotate, and the bottom of the scraper contacts the bottom of the premixing box, the smooth discharge of the dry material is ensured.
[0015] The invention relates to a method for reinforcing brick masonry structures with UHP-ECC material containing PE fibers and its preparation. A lifting mechanism is used to move the connecting arm and premixing box when UHP-ECC material is needed for reinforcement. Simultaneously, the connecting arm slides on both sides of the support base, moving the premixing box to the top of the mixing tank for subsequent preparation. After preparation, the premixing box is moved away from the top of the mixing tank, facilitating subsequent cleaning and ensuring the quality of the prepared material.
[0016] The method for reinforcing brick masonry structures with PE fiber-containing UHP-ECC material and its preparation involves a feeding mechanism. After the UHP-ECC material is prepared, a collection device is placed at the bottom of the feeding pipe. A third hydraulic cylinder drives a fixed plate to move forward within the fixed plate and platform, thus feeding the UHP-ECC material. When the rotating rod rotates, it drives the second scraper to rotate, and the bottom of the second scraper contacts the bottom of the mixing box, ensuring smooth feeding and avoiding material residue. After feeding, workers can evenly apply the UHP-ECC material to the cleaned masonry surface for reinforcement. Attached Figure Description

[0028] Please see Figure 1-9 Furthermore, based on Examples 1 and 2, the feeding mechanism 4 is further provided, which includes a feeding pipe 41, the feeding pipe 41 being fixedly connected to the bottom of the mixing box 22, a fixing plate 42 being slidably connected inside the feeding pipe 41, the fixing plate 42 being slidably connected inside the fixing platform 21, and a third hydraulic cylinder 43 being fixedly connected to the front side of the fixing plate 42, the third hydraulic cylinder 43 being fixedly connected to the front side of the fixing platform 21.
[0029] The feeding tube 41 extends through the inside of the fixed platform 21, facilitating the feeding of the prepared UHP-ECC material through the feeding tube 41.
[0030] The preparation method of UHP-ECC material containing PE fiber to reinforce brick masonry includes the following steps: Dry Mix of S1 and UHP-ECC Materials First, the second hydraulic cylinder 33 drives the connecting arm 34 and the premix box 23 to move, so that the bottom of the premix box 23 contacts the top of the mixing box 22. At this time, the proportioned cement, silica fume, fly ash, fine aggregate and other mineral admixtures and fine aggregates can be poured into the premix box 23. The first servo motor 26 drives the first stirring shaft 29 and the first scraper 291 fixedly connected to the outside of the rotating rod 27 to rotate. Under the action of the first stirring shaft 29 and the first scraper 291, the aggregate in the premix box 23 can be dry mixed. After the dry mixing is completed, the first hydraulic cylinder 294 drives the baffle 295 to move to the left. At this time, the bottom of the premix box 23 can be opened, and the dry material after dry mixing can enter the mixing box 22. Because the rotating rod 27 drives the first scraper 291 to rotate and the bottom contacts the bottom of the premix box 23, the smoothness of the dry material discharge can be guaranteed. S2, UHP-ECC material wet mixing When the dry material after dry mixing enters the mixing chamber 22, the rotating rod 27 will synchronously drive the second stirring shaft 292 and the second scraper 293 to rotate. During the mixing process, the water-reducing agent is pre-dissolved in water and then slowly added to the dry material being mixed through the water injection pipe 299. The mixing continues. After a certain period of mixing, the PE fiber after the proportioning is completed can be put into the hopper 24. The second servo motor 296 drives the rotating shaft 297 and the sealing plate 298 to rotate. By adjusting the angle of rotation of the sealing plate 298 inside the hopper 24, the speed and amount of PE fiber feeding can be controlled, so that the PE fiber enters the dry material being mixed in the mixing chamber 22 in small amounts and multiple times, ensuring that the fiber is evenly dispersed and avoiding clumping. S3 and UHP-ECC material cutting Once the UHP-ECC material is prepared, the collection device can be placed at the bottom of the discharge pipe 41. The third hydraulic cylinder 43 drives the fixed plate 42 to move forward within the discharge pipe 41 and the fixed platform 21, thus discharging the UHP-ECC material. When the rotating rod 27 rotates, it will drive the second scraper 293 to rotate, and the bottom of the second scraper 293 will contact the bottom of the mixing box 22, which will ensure the smoothness of the discharge and avoid material residue. After the discharge is completed, the workers can evenly apply the UHP-ECC material to the cleaned masonry surface.
[0031] In actual operation, when this device is used, and it is necessary to reinforce the brick masonry by preparing UHP-ECC material, the second hydraulic cylinder 33 drives the connecting arm 34 and the premix box 23 to move. At the same time, the front and rear sides of the connecting arm 34 slide inside the support base 31, which can drive the premix box 23 to the top of the mixing box 22 for subsequent preparation work. The support base 31, the partition plate 32, the second hydraulic cylinder 33 and the connecting arm 34 are provided in two sets to ensure the balance and stability of the premix box 23 when it is raised and lowered. At this point, the proportioned cement, silica fume, fly ash, fine aggregate, and other mineral admixtures and fine aggregates can be poured into the premixing box 23. The first servo motor 26 drives the first stirring shaft 29 and the first scraper 291, which are fixedly connected to the outside of the rotating rod 27, to rotate. Under the action of the first stirring shaft 29 and the first scraper 291, the aggregates in the premixing box 23 can be dry-mixed. After the dry mixing is completed, the first hydraulic cylinder 294 drives the baffle 295 to move to the left. At this time, the bottom of the premixing box 23 can be opened, and the dry material after dry mixing can enter the mixing box 22. Because the rotating rod 27 drives the first scraper 291 to rotate and the bottom is in contact with the bottom of the premixing box 23, the smoothness of the dry material discharge can be ensured. When the dry material after dry mixing enters the mixing chamber 22, the rotating rod 27 will synchronously drive the second stirring shaft 292 and the second scraper 293 to rotate. During the mixing process, the water-reducing agent is pre-dissolved in water and then slowly added to the dry material being mixed through the water injection pipe 299. The mixing continues. After a certain period of mixing, the PE fiber after the proportioning is completed can be put into the hopper 24. The second servo motor 296 drives the rotating shaft 297 and the sealing plate 298 to rotate. By adjusting the angle of rotation of the sealing plate 298 inside the hopper 24, the speed and amount of PE fiber feeding can be controlled, so that the PE fiber enters the dry material being mixed in the mixing chamber 22 in small amounts and multiple times, ensuring that the fiber is evenly dispersed and avoiding clumping. This completes the preparation of UHP-ECC material. Once the UHP-ECC material is prepared, the collection device can be placed at the bottom of the discharge pipe 41. The third hydraulic cylinder 43 drives the fixed plate 42 to move forward within the discharge pipe 41 and the fixed platform 21, thus discharging the UHP-ECC material. When the rotating rod 27 rotates, it will drive the second scraper 293 to rotate, and the bottom of the second scraper 293 will contact the bottom of the mixing box 22, which will ensure the smoothness of the discharge and avoid material residue. After the discharge is completed, the workers can evenly apply the UHP-ECC material to the cleaned masonry surface. When the preparation is completed and it is necessary to clean the inside of the mixing box 22, the premixing box 23 can be moved away from the top of the mixing box 22 by the action of the two sets of second hydraulic cylinders 33, so that the staff can clean the inside of the mixing box and ensure the quality of subsequent material preparation. In this application, all the first hydraulic cylinders 294, the second hydraulic cylinders 33, the third hydraulic cylinders 43, the first servo motor 26, and the second servo motor 296 need to be connected to the same PLC controller near the equipment to ensure the coordinated operation of the equipment. The PLC controller is existing technology, and those skilled in the art are well aware of its operation method, so it will not be described in detail here.

10. A method for preparing UHP-ECC material-reinforced brick masonry containing PE fibers, characterized in that: The above-mentioned method for preparing UHP-ECC material containing PE fiber to reinforce brick masonry includes the following steps: Dry Mix of S1 and UHP-ECC Materials First, the connecting arm (34) and the premix box (23) are moved by the second hydraulic cylinder (33) so that the bottom of the premix box (23) contacts the top of the mixing box (22). At this time, the proportioned cement, silica fume, fly ash, fine aggregate and other mineral admixtures and fine aggregates can be poured into the premix box (23). The first servo motor (26) drives the first stirring shaft (29) and the first scraper (291) fixedly connected to the outside of the rotating rod (27) to rotate. The first stirring shaft (29) rotates. Under the action of the first scraper (291), the aggregate in the premix box (23) can be dry mixed. After the dry mixing is completed, the first hydraulic cylinder (294) can drive the baffle (295) to move to the left. At this time, the bottom of the premix box (23) can be opened, and the dry material after the dry mixing is completed can enter the mixing box (22). Because the rotating rod (27) drives the first scraper (291) to rotate, and the bottom contacts the bottom of the premix box (23), the smoothness of the dry material discharge can be guaranteed. S2, UHP-ECC material wet mixing When the dry material after dry mixing enters the mixing box (22), the rotating rod (27) will synchronously drive the second stirring shaft (292) and the second scraper (293) to rotate. During the mixing process, the water-reducing agent is pre-dissolved in water and then slowly added to the dry material being mixed through the water injection pipe (299). The mixing continues. After a certain period of mixing, the PE fiber after the proportioning is completed can be put into the hopper (24). The rotating shaft (297) and the sealing plate (298) are driven to rotate by the second servo motor (296). By adjusting the angle of rotation of the sealing plate (298) inside the hopper (24), the speed and amount of PE fiber feeding can be controlled, so that the PE fiber enters the dry material being mixed in the mixing box (22) in small amounts and multiple times, ensuring that the fiber is evenly dispersed and avoiding clumping. S3 and UHP-ECC material cutting Once the UHP-ECC material is prepared, the collection device can be placed at the bottom of the discharge pipe (41). The third hydraulic cylinder (43) drives the fixed plate (42) to move forward in the discharge pipe (41) and the fixed platform (21) to discharge the UHP-ECC material. When the rotating rod (27) rotates, it will drive the second scraper (293) to rotate. The bottom of the second scraper (293) contacts the bottom of the mixing box (22), which can ensure the smoothness of the discharge and avoid material residue. After the discharge is completed, the staff can evenly apply the UHP-ECC material to the cleaned masonry surface.
