Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete crack control technology, and in particular to a concrete crack control structure. Background Technology
[0002] Water retention curing refers to the curing of concrete by storing water. Water retention curing can effectively keep the concrete surface moist, thereby promoting the hydration reaction of cement, improving the strength and durability of concrete, and preventing the concrete surface from drying and cracking.
[0003] Before water curing concrete, a water-retaining embankment needs to be built around the edge of the initially set concrete surface using bricks or mortar. Then, water is stored inside the embankment to cure the concrete. This increases the number of construction steps for workers. Furthermore, the construction of the embankment and the concrete pouring are not carried out at the same time, which can easily lead to gaps and water leakage.
[0004] Therefore, it is necessary to provide a new concrete crack control structure to solve the above problems. Utility Model Content
[0005] The technical problem solved by this utility model is to provide a concrete crack control structure that is easy to construct and accelerates construction efficiency.
[0006] To solve the above-mentioned technical problems, the concrete crack control structure provided by this utility model includes: a fixing plate, which abuts against the inner side wall of the top of the template, and concrete is poured inside the template; the bottom end of the fixing plate is inclined downward and fixedly connected to a base plate; rubber pads are installed on the side walls of the fixing plate and the base plate, the bottom end of the rubber pads is inclined downward, and the thickness of the bottom end of the rubber pads gradually increases along the template towards the base plate.
[0007] Preferably, the side wall of the fixing plate is fixedly connected to the buckle plate, the side wall of the buckle plate engages with the template, and the side wall cross-section of the buckle plate has an "L" shaped structure.
[0008] Preferably, multiple clamping plates are installed on the top sidewall of the fixing plate, and the sidewalls of the clamping plates are rotatably connected to a rotating plate. The rotating plate, with its sidewall in the shape of an "L", is threadedly connected to a screw, and the screw abuts against the sidewall of the template or the concrete.
[0009] Preferably, the clamp plate is rotatably connected to a rotating shaft, and the rotating shaft is fixedly connected to the rotating plate; the interior of the clamp plate is threadedly connected to a knob, and the knob abuts against the side wall of the rotating shaft.
[0010] Compared with related technologies, the concrete crack control structure provided by this utility model has the following beneficial effects:
[0011] This utility model provides a concrete crack control structure. After the formwork for pouring concrete is erected, a fixing plate is placed on the surface of the formwork. The fixing plate is fixed above the formwork by a buckle plate. The rotating plate is rotated so that it is perpendicular to the fixing plate. The screw is rotated, and the screw gradually moves closer to the formwork and presses against it, thereby fixing the fixing plate to one side of the formwork. Then, concrete is poured inside the formwork. During concrete curing, part of the fixing plate and the rubber pad are poured into the concrete. A waterproof tape is pasted around the joint of the fixing plate to prevent water leakage at the joint. Then, water is poured on the concrete surface. The rubber pad is located above the concrete to prevent water from flowing out of the concrete surface, thus performing water retention curing on the concrete surface and reducing cracks on the concrete surface. No manual labor is required. The construction of the water-retaining embankment is accelerated by manually pouring concrete. After the formwork is removed, the rotating plate is rotated so that one side of the rotating plate abuts against the side wall of the concrete. The screw is rotated so that it tilts upward and squeezes the side wall of the concrete. As the screw rotates, it pushes the rotating plate to pull the top of the fixing plate. The bottom end of the fixing plate is tilted downward to install the base plate and the rubber pad. The top of the fixing plate rotates downward, pushing the base plate and the rubber pad on its surface to move upward and squeeze the interior of the concrete, thereby fixing the base plate and the rubber pad inside the concrete. This prevents the rubber pad and the fixing plate from easily detaching from the concrete during water storage, facilitating water storage. Furthermore, the thickness of the bottom end of the rubber pad gradually increases along the formwork towards the base plate, increasing the stability of the rubber pad inside the concrete and preventing the rubber pad from easily detaching from the concrete.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0019] Please see Figures 1 to 5 , Figure 1 A schematic diagram of a preferred embodiment of the concrete crack control structure provided by this utility model; Figure 2 for Figure 1 The diagram shows an enlarged view of the structure at point A. Figure 3 for Figure 1 The diagram shows a concrete structure. Figure 4 for Figure 2 The diagram shows the structure of the fixed plate. Figure 5 for Figure 2 The diagram shows the internal structure of the formwork. The concrete crack control structure includes: a fixing plate 4, which abuts against the inner top wall of the formwork 1, and concrete 2 is poured inside the formwork 1; the bottom end of the fixing plate 4 is inclined downwards and fixedly connected to a base plate 41; rubber pads 3 are installed on the side walls of the fixing plate 4 and the base plate 41, with the bottom end of the rubber pads 3 inclined downwards, and the thickness of the bottom end of the rubber pads 3 gradually increasing along the formwork 1 towards the base plate 41; a buckle plate 42 is fixedly connected to the side wall of the fixing plate 4, and the side wall of the buckle plate 42 is secured... The template 1 is assembled, and the side wall of the buckle plate 42 has an "L" shaped cross-section; multiple clamping plates 5 are installed on the top side wall of the fixing plate 4, and the side wall of the clamping plate 5 is rotatably connected to the rotating plate 6. The rotating plate 6 with the "L" shaped side wall is threadedly connected to the screw 7, and the screw 7 abuts against the side wall of the template 1 or the concrete 2; the inside of the clamping plate 5 is rotatably connected to the rotating shaft 8, and the rotating shaft 8 is fixedly connected to the rotating plate 6; the inside of the clamping plate 5 is threadedly connected to the knob 9, and the knob 9 abuts against the side wall of the rotating shaft 8. After the formwork for pouring concrete is erected, the fixing plate 4 is placed on the surface of the formwork 1. The fixing plate 4 is fixed above the formwork 1 by the buckle plate 42. The rotating plate 6 is rotated, which drives the rotating shaft 8 to rotate inside the clamping plate 5, making the rotating plate 6 perpendicular to the fixing plate 4. The knob 5 is then turned to press against the side wall of the rotating shaft 8, fixing the rotating plate 6 to one side of the fixing plate 4. Then the screw 7 is rotated, which gradually moves closer to the formwork 1 and presses against the formwork 1, thereby fixing the fixing plate 4 to one side of the formwork 1. Concrete is then poured inside the formwork 1. During concrete curing, part of the fixing plate 4 and the rubber pad 3 are poured into the interior of the concrete (as shown in the attached diagram). Figure 2 As shown in the diagram, a ring of waterproof tape is pasted at the joint of the fixing plate 4 to prevent water leakage at the joint of the fixing plate 4. Then, water is poured on the concrete surface. The rubber pad 3 is located above the concrete, and the fixing plate 4 provides support for the rubber pad 3, preventing water from flowing out of the concrete surface. This water retention and curing of the concrete surface reduces cracks on the concrete surface and eliminates the need for workers to pour a water-retaining sill, thus speeding up construction efficiency. After the template 1 is removed, the knob 5 is rotated to separate from the rotating shaft 8, and then the rotating plate 6 is rotated so that one side of the rotating plate 6 contacts the concrete. Rotate knob 5 to press the rotating shaft 8 to fix the rotating plate 6; then rotate screw 7 to tilt screw 7 upward to press the side wall of concrete 2. As screw 7 rotates, it pushes the rotating plate 6 to pull the top of the fixing plate 4. The bottom end of the fixing plate 4 is tilted downward to install the base plate 41 and the rubber pad 6. The top of the fixing plate 4 rotates downward to push the base plate 41 and the rubber pad 6 on its surface to move upward to press the interior of the concrete, thereby fixing the base plate 41 and the rubber pad 3 inside the concrete (as shown in the attached figure). Figure 3 As shown, this design prevents the rubber pad 3 and the fixing plate 4 from easily detaching from the concrete during water storage, facilitating water storage. Furthermore, the thickness of the bottom end of the rubber pad 3 gradually increases along the template 1 towards the base plate 41, increasing the stability of the rubber pad 3 within the concrete 2 and preventing it from easily detaching. After the concrete 2 has cured, the screw 7 is rotated to separate from the surface of the concrete 2, and the fixing plate 4 is pulled upwards at an angle. The surface of the rubber pad 3 is elastic, and the rubber pad 3 is deformed by the concrete compression, causing the bulge 4 and the rubber pad 3 to slide out from the interior of the concrete.
